FIELD OF THE INVENTION

The disclosure relates to a scooter having two front wheels more specifically, to scooters having two front and wheels controlled by a steering post that is coupled with a steering mechanism such that, when the steering post is pivoted, the steering mechanism synchronizes the tilt of the steering post to incline towards the inside periphery of the turning curve. The scooter may further be a foldable scooter.

BACKGROUND

Scooters are means of transport that are typically of small dimensions, allowing the rider to carry it by hand, when not in use, and in some cases, also capable of collapsing from running position into carry-on/storage position or vice versa (herein after also referred to as “folding”).

US patent US 9272739 by Amir Zaid et al, discloses a scooter including a deck portion mounted on a pair of front wheels; at least one tail portion foldably coupled to the deck portion and being narrower than the deck portion and mounted on at least one rear wheel thereby providing the deck portion with stability. The scooter further includes a steering post coupled to the front wheels and being foldable with respect to the deck portion.

US patent US 10322767 by Costel Dragomir, discloses an improved pedal driven scooter may have a mainframe, a joint-frame, a front balance and steering mechanism, one or two front steering wheel (s), a rear drive wheel, and a drive mechanism. The pedals are pushed rearward and move independent of each other within an adjustable angle range. The drive mechanism translates the alternative movement of the pedals into unidirectional rotation, which is further multiplied, and drives the real wheel. A leaning control mechanism allows a rider to stay mounted when the vehicle is stopped. The scooter can be folded with the joint frame pivoting at both ends, such that the rear- wheel docks between or near the front wheel (s) and the scooter can be carried as if it were a carry-on luggage. The scooter may be further folded for storage with the help of a folding hinge which connects a lower part and an upper part of the front steering mechanism. The term ‘scooter’ as used herein in the specification and claims is used to denote any of a variety of vehicles, scooters, motorized scooters, mopeds, etc. or any transportation device, having a steering post and at least two front wheels, for carrying one or more riders.

One of the drawbacks of prior art scooters is the small dimensions of such vehicle that may render it unsafe to ride. Some prior art scooters, when turning, the steering post remain in an upright orientation. Therefore, often, when riding a vehicle having two front wheels and doing a turn, due to centrifugal forces, the wheel disposed at the inside periphery of the turning curve, tend to lose grip of the road including being lifted in the air. Furthermore, the front wheels incline towards the inside periphery of the turning curve, to further lose grip of the road.

Hence, there is a need, and it would be advantageous to have a mechanism that when the driver pivots the steering post to make a turn, the mechanism automatically and synchronously, tilts the steering post towards the inside periphery of the turning curve, while keeping the two front wheels upright orientation, when riding in reasonable speed. It would be further advantageous for the scooter to be foldable and be stored away, or into a trolley that can be carried as if it were a carry-on luggage.

The teachings provided herein can be applied to other systems, not only the systems described herein. The elements and acts of the various embodiments described above can be combined to provide further embodiments.

According to one aspect of the present disclosure there is provided a scooter having two front wheels that are controlled by a steering post that is part of a steering mechanism that, when the steering post is rotated, the steering mechanism synchronizes the tilt of the steering post to incline sideways towards the inside periphery of the turning curve. Furthermore, the standing board of the scooter is configured to incline sideways towards the inside periphery of the turning curve. Furthermore, steering mechanism is designed to keep the two front wheels upright, including when turning.

According to another aspect of the present disclosure there is provided a foldable scooter that can fold into a trolly, including the deck assembly. The foldable scooter may further include a detachable bag, wherein the scooter can fold into a trolly, including the deck assembly and the detachable bag.

Reference is now made to the drawings. Fig. 1 schematically illustrates a first, non-limiting example embodiment of a scooter 100, including a steering post 110, a deck assembly 120 having a standing board 121 and a rear wheel assembly 170, a steering mechanism 130 and an optional detachable bag 199, according to aspects of the present disclosure, wherein the steering post 110 is in straight, upright position. Standing board 121 is configured to incline sideways towards the inside periphery of the turning curve, and configured for supporting a rider, typically standing thereon.

Steering post 110 can include a handle-bar 118 having two handle-grips 116 aiding a rider of scooter 100 to turn either to the left or to the right by pivoting steering post 110 accordingly. A main aspect of the present disclosure us to provide a mechanism that, when steering post 110 is pivoted, steering post 110 is also forced to incline sideways towards the inside periphery of the turning curve. Typically, the pivotal axis 115 of steering post 110 is operatively situated on the longitudinal axis 105 of scooter 100.

Hence, steering mechanism 130 facilitates the rider, when turning steering post 110 to turn scooter 100 either to the left or to the right, at his/her will. Fig. 2 schematically illustrates the scooter 100 in a state where the steering post 110 is pivoted to the left, in direction 117, and thereby also tilted to the left, according to aspects of the present disclosure. Fig. 3 is a rear perspective view, schematic illustration of the scooter 100, according to aspects of the present disclosure, wherein the steering post 110 is pivoted to the right and thereby also tilted to the right. The tilting measure dictates the tilting measure at a constant preconfigured rate. In one embodiment, steering post 110 is subdivided into an upper-post 112 and a lower-post 114, wherein upper-post 112 may slide over lower-post 114, telescopically. Steering mechanism 130 further includes a pair of front wheels 132 interconnected by a steering mechanism to steering post 110, wherein when steering post 110 is pivoted, each of the front wheels (132L, 132R) is also pivoted in the same direction by a wheel s-pivoting-mechanism 150, as shown in Fig. 4. Fig. 4 is a top perspective view, schematic illustration of the front section of the scooter 100 as shown Fig. 3, according to aspects of the present disclosure, wherein the non-limiting example shown for the wheel s-pivoting-mechanism 150 is based on the Ackerman Steering Principle (ASP). In such an ASP steering mechanism, the inner front wheel needs to turn at a different angle than the outer wheel because they are turning on different radii. The ASP steering mechanism is a geometric arrangement of linkage components (such as 146, 154, 156) in wheel s-pivoting-mechanism 150 designed to turn the inner and outer wheels at the appropriate angles. Any other mechanism known in the art for coordinately pivot both front wheels, such as in cars, may be used (and not as, for example, in a “carriage” mechanism). The example wheel s-pivoting-mechanism 150 includes pivoting receiving linkage component 146, receiving the pivotal motion from steering post 110, whereas the motion is transmitted to front wheels 132L and 132R, respectively, by the respective rods 154, to respective linkage components 156, to which respective linkage component 156 the respective front wheel 132 is rotatably attached. It should be appreciated that while the scooter 100 is in a turn instance position, the pivoted front wheels (132L, 132R) remain in an upright orientation, wherein both wheels remain firmly on the road, when riding in reasonable speed. Each linkage components 156 (156L, 156R) further include a respective independent shaft 158 (158L, 158R), about which shaft 158 the respective front wheel (132L, 132R) pivots, when making a turn.

Rear wheel assembly 170 includes a rear wheel 172 rotatable connected to a rear shaft. Rear wheel assembly 170 includes may further include a brake mechanism 174. Rear wheel assembly 170 may be operated by a motor, such as an electric motor (not shown).

Similarly, Fig. 6a is a front view of the scooter 100, schematically illustrating steering mechanism 130, wherein for visibility purposes only, some occluding parts have been removed for illustration purposes only, and wherein scooter 100 is shown in a left turn instance position.

Fig. 5b is a front view, schematic illustration of steering mechanism 130 of the scooter 100, shown in a deployed position. Fig. 5b illustrates components that take part in facilitating scooter 100 to turn either left or right. Similarly, Fig. 6b is a front view, schematic illustration of the steering mechanism 130 of the scooter 100, shown in a left turn instance position. Fig. 6b illustrates components that take part in facilitating scooter 100 to turn (left turn in the non-limiting example shown in Fig. 6b). The steering mechanism 130 components that take part in facilitating scooter 100 to turn, with automatic tilt of the steering post 110, include steering post 110, a pair of front wheels 132, a tilt-synchronizing unit 140 and a pair of balancing-actuators 148, shown as a pair of springs, by way of example only. Balancing-actuators 148 may also be embodied, for example, as a pair of pneumatic or hydraulic mechanisms.

The steering mechanism 130 further includes two frame elements: pivotal-frame element 188 and non-pivotal-frame element 180. Pivotal-frame element 188 is configured to receive the pivotal motion from tilt-synchronizing unit 140, wherein pivotal-frame element 188 is pivotally connected to non-pivotal-frame element 180 at a bearing 185 disposed at a laterally central location of non-pivotal-frame element 180. The lower ends 149 (149R, 149L) of balancing-actuators 148 are securely connected to non-pivotal-frame element 180 at respective locations, and the upper ends 147 (147R, 147L) of balancingactuators 148 are securely connected to non-pivotal-frame element 180 at respective locations. Hence, balancing-actuators 148 actuate the relative rotational power forces between non-pivotal-frame element 180 and balancing-actuators 148, and asserting a steering-post-return-force counter to the pivotal force applied by the driver on the steering post 110. Once the driver weakens or releases the pivotal force (or turns back the steering post 110), the balancing-actuators 148 pivots the steering post 110 towards a straight, upright position of steering post 110. It should be appreciated that a balancing-actuators 148 may store a biasing force by either compressing compressible balancing-actuators 148, or by pulling balancing-actuators 148. The present disclosure is described as if balancing-actuators 148 pulled, and biasing force tries to return to its idle, non-stretched state. It should be further appreciated that standing board 121, being attached to pivotal- frame element 188, is configured to incline sideways towards the inside periphery of the turning curve, together with pivotal-frame element 188 (for example, see Fig. 6a).

To further clarify the steering mechanism 130 and the inter-relation between pivotal-frame element 188 and non-pivotal-frame element 180, a steering-tilt assembly 131a and 131b is introduced, with reference to Figs. 7a and 7b, respectively. While Fig. 7a shows also pivotal-frame element 188, in Fig. 7b pivotal-frame element 188 has been removed for illustrative purposes only, to unveil a tilt-synchronizing unit 140 and a pair of truncated rotating-cones 142, that together, facilitate automatic tilt of the steering post 110, when pivoting steering post 110. Fig. 7c shows a detailed A view of a tiltsynchronization assembly 155 including tilt-synchronizing unit 140 and non-pivotal- frame element 180 that are pivotally interconnected via a shaft 185. Fig. 8a is a front view schematic illustration of tilt-synchronizing unit 140 of an example steering mechanism 130, the scooter 100 being in a deployed position. Tilt-synchronizing unit 140 includes a post interface section 141 having a rotational axis the coincides with pivotal axis 115 of steering post 110, a pivoting receiving linkage component 146, and a synchronizing body

143. Fig. 8b is a side elevated view of an exemplary tilt-synchronizing unit 140 of steering mechanism 130, the scooter 100 shown in a deployed position, being in a straight, upright position. Fig. 8c is a bottom perspective view, schematic illustration of tilt-synchronizing unit 140 of steering mechanism 130, the scooter 100 shown in a deployed position.

Synchronizing body 143 includes two arched walls 145, wherein arched walls 145 are shown to be part of an imaginary cylindrical thick wall 139 having a thickness W1 and an axis that operatively coincides with pivotal axis 115 of steering post 110. The arched walls 145 are diagonally truncated at their bottom, at an angle a (see Fig. 8b), with respect to an imaginary plane that is perpendicular to pivotal axis 115, forming flat faces

144, including right face 144R and left face 144L. It should be noted that angle a may vary along flat faces 144. Flat faces 144 are also sloped laterally (with respect to pivotal axis 115), going downwardly at an angle P (see Fig. 8a), as extending from the periphery of arched walls 145 inwardly towards pivotal axis 115.

Fig. 9a is a front view schematic illustration of tilt-synchronizing unit 140 of steering mechanism 130, the scooter 100 being in a deployed position, wherein tiltsynchronizing unit 140 is operatively paired, respectively, with a pair of truncated rotating-cones 142. Fig. 9b is a side elevated view schematic illustration of tiltsynchronizing unit 140 of scooter 100, the scooter 100 being in a deployed position. A truncated rotating-cone 142 has a slope p with respect to its central axis 113, such that when the sloped periphery of truncated rotating-cone 142 is operatively placed against the respective inclined flat face 144, axis 113 is substantially perpendicular pivotal axis 115

Fig. 10a is a front perspective view schematic illustration of tilt-synchronizing unit 140 of steering mechanism 130, the scooter 100 shown, by way of example, in a left turn instance position, as described with reference to Fig. 8a, tilt-synchronizing unit 140 includes a post interface section 141 having a rotational axis the coincides with pivotal axis 115 of steering post 110, a pivoting receiving linkage component 146, and a synchronizing body 143. Fig. 10b is a rear perspective view of tilt-synchronizing unit 140 of steering mechanism 130, the scooter 100 shown, by way of example, in a left turn instance position.

Synchronizing body 143 includes, for example, two arched walls 145, wherein arched walls 145 are part of an imaginary cylindrical thick wall 139 having a thickness W1 and an axis that operatively coincides with pivotal axis 115 of steering post 110. The arched walls 145 are diagonally truncated at their bottom, at an angle a (see Fig. 8b), with respect to an imaginary plane that is perpendicular to pivotal axis 115, forming flat faces 144, including right face 144R and left face 144L. Flat faces 144 are also sloped laterally (with respect to pivotal axis 115), going downwardly at an angle p (see Fig. 10a), as extending from the periphery of arched walls 145 inwardly towards pivotal axis 115.

Fig. I la is a front perspective view schematic illustration of tilt unit 140 of steering mechanism 130, the scooter 100 is shown, by way of example, in a left turn instance position, wherein tilt-synchronizing unit 140 is operatively paired, respectively, with a pair of truncated rotating-cones 142. Fig. 1 lb is a rear perspective view schematic illustration of tilt-synchronizing unit 140 of scooter 100, the scooter 100 shown, by way of example, in a left turn instance position. A truncated rotating-cone 142 has a slope P with respect to its central axis 113, such that when the sloped periphery of truncated rotating-cone 142 is operatively placed against the respective inclined flat face 144, axis 113 of the truncated rotating-cone 142 is substantially perpendicular pivotal axis 115. It should be appreciated that when scooter 100 is in the deployed position, the scooter 100 is in an idle state, including balancing-actuators 148. Balancing-actuators 148, having an initial tension force F, balance each other such that truncated rotatingcones 142 are positioned adjacent to the respective sloped flat faces 144 at a central section of sloped flat faces 144, substantially at the same respective location of flat faces 144, as shown in a non-limiting example in Figs. 9a and 9b.

It should be further appreciated that while the scooter 100 is in a turn position, the pivoted front wheels (132L, 132R) remain in an upright orientation, wherein both wheels remain firmly on the road, when riding in reasonable speed. Furthermore, each of the pivoted front wheels (132L, 132R) is configured to pivot about a respective independent shaft 158 turning radius. Referring back to Fig. 6a that illustrates a front view of the scooter 100, wherein scooter 100 is shown in a left turn instance position. It can be clearly seen that while pivotal-frame element 188 is tilted, along with steering post 110, into the side of the turn, pivotal-frame element 188 tilts about shaft 185 of non-pivotal-frame element 180, and non-pivotal-frame element 180 remains non-tilted, generally parallel to the ground surface. Thereby, pivoted front wheels (132L, 132R) remain in an upright orientation, wherein both wheels remain firmly on the road, when riding in reasonable speed. Furthermore, each of the pivoted front wheels (132L, 132R) is configured to pivot about a respective independent shaft 158.

In order to bring scooter 100 from the idle state to the left turn instance position desired direction, as shown by way of example in Figs. I la and 1 lb, (the left turn being a non-limiting example to any desired direction of the driver), the driver of scooter 100 pivots steering post 110 to the left about pivotal axis 115, while applying a pivotal force FP, typically, by using one or both handle-grips 116. The driver’s pivotal action initiates to following chain of reaction: a. steering post 110 pivots to the left, about pivotal axis 115, against a resisting force Fs of balancing-actuators 148. b. tilt-synchronizing unit 140, being securely attached to steering post 110 pivots with steering post 110. c. as tilt-synchronizing unit 140 pivots, sloped flat faces 144 pivots too, applying friction force FF onto the sloped periphery of truncated rotatingcone 142 d. truncated rotating-cones 142 (142R and 142L), being mounted on respective stationary shafts 138 (see Figs. 7b and 7c, 138R and 138L) that are secured to non-pivotal-frame element 180, are free to rotate about the respective stationary shafts 138, sloped flat faces 144 pivot while rolling over the sloped periphery of the freely rotating truncated rotating-cones 142 (142R and 142L). It should be appreciated that the group: tilt-synchronizing unit 140, truncated rotating-cones 142 (142R and 142L) and the respective stationary shafts 138 (138R and 138L), may be referred to as tilt-synchronization assembly 155 (see Fig. 7c).

It should be further appreciated that sloped flat faces 144 roll over the respective sloped periphery of the freely rotating truncated rotating-cones 142, because of the friction force FF that exists between the two sloped surfaces. It should be further appreciated that the friction force FF may cause erosion of surfaces of flat faces 144 and/or 142, which erosion can be calibrated by a calibration mechanism (for example calibrating the attaching bolt of the respective stationary shaft 138, see Figs. 7b and 7c) that moves the sloped periphery of the freely rotating truncated rotating-cones 142 along rotational axis 113, while sloped flat faces 144 remains stationary. e. because of the angle a (see Fig. 8b) of sloped flat faces 144, one arched wall 145 moves upwards (145R in this example) as the respective flat face 144 (the right face 144R in this example) the right arched wall 145R (in this example) moves upwards, while rolling over the respective sloped periphery of truncated rotating-cones 142R(in this example), and the other arched wall 145 moves downwards or remains idle (145L in this example) as the respective flat face 144 (the left face 144L in this example) moves downwards, while rolling over the respective truncated rotating-cone 142L.

As long as the driver keeps pivoting steering post 110, pivoting steering post 110 also tilts into the selected turn side.

As steering post 110 continues to tilt, one balancing-actuator 148 (the right balancing-actuator 148R in this example) increases its tension with respect to initial tension force F, while the other balancing-actuator 148 (the left balancing-actuator 148L in this example) decreases its tension with respect to initial tension force Ft. It should be appreciated that the balancing-actuators 148 being unbalanced, tend to balance their tension forces, that is return the idle state where their initial tension force Fi. therefore, once the driver weakens or releases the pivotal force, the balancing-actuators 148 pivots the steering post 110 towards a straight, upright position of steering post 110.

Fig. 22 schematically illustrates a second, non-limiting example embodiment of a scooter 500, including a steering post 510, a deck assembly 520 having a standing board 521 and a rear wheel assembly 570, a steering mechanism 530 and an optional detachable bag 599, according to aspects of the present disclosure, wherein the steering post 510 is in straight, upright position. Standing board 521 is configured to incline sideways towards the inside periphery of the turning curve, and configured for supporting a rider, typically standing thereon.

Steering post 510 can include a handle-bar 518 having two handle-grips 516 aiding a rider of scooter 500 to turn either to the left or to the right by pivoting steering post 510 accordingly. A main aspect of the present disclosure is to provide a mechanism that, when steering post 510 is pivoted, steering post 510 is also forced to incline sideways towards the inside periphery of the turning curve. Typically, the pivotal axis 515 of steering post 510 is operatively situated on the longitudinal axis 505 of scooter 500.

Hence, steering mechanism 530 facilitates the rider, when turning steering post 510 to turn scooter 500 either to the left or to the right, at his will. Fig. 23 schematically illustrates the scooter 500 in a state where the steering post 510 is pivoted to the left, in direction 517, and thereby also tilted to the left, according to aspects of the present disclosure. Fig. 24 is a rear perspective view, schematic illustration of the scooter 500, according to aspects of the present disclosure, wherein the steering post 510 is pivoted to the left and thereby also tilted to the left. The tilting measure dictates the tilting measure at a constant preconfigured rate. In one embodiment, steering post 510 is subdivided into an upper-post 512 and a lower-post 514, wherein upper-post 512 may slide over lower- post 514, telescopically.

Steering mechanism 530 further includes a pair of front wheels 532 interconnected by a steering mechanism to steering post 510, wherein when steering post 510 is pivoted, each of the front wheels (532L, 532R) is also pivoted in the same direction by a wheel s-pivoting-mechanism 550, as shown in Fig. 25. Fig. 25 is a top perspective view, schematic illustration of the front section of the scooter 500, according to aspects of the present disclosure, wherein the non-limiting example shown for the wheels- pivoting-mechanism 550 is based on the Ackerman Steering Principle (ASP). In such an ASP steering mechanism, the inner front wheel needs to turn at a different angle than the outer wheel because they are turning on different radii. The ASP steering mechanism is a geometric arrangement of linkage components (such as 567, 552, 554, 556) in wheels- pivoting-mechanism 550 designed to turn the inner and outer wheels at the appropriate angles. Any other mechanism known in the art for coordinately pivot both front wheels, such as in cars, may be used (and not as, for example, in a “carriage” mechanism). The example wheel s-pivoting-mechanism 550 includes pivoting receiving linkage components 556, receiving the pivotal motion from steering post 510, whereas the motion is transmitted to front wheels 532L and 532R, by a pair of axially moving rods, 552 and 554, to respective linkage components 556, to which respective linkage component 556 the respective front wheel 532 is rotatably attached. It should be appreciated that while the scooter 500 is in a turn instance position, the pivoted front wheels (532L, 532R) remain in an upright orientation, wherein both wheels remain firmly on the road, when riding in reasonable speed. Each linkage components 556 (556L, 556R) further include a respective independent shaft 558 (558L, 558R), about which shaft 558 the respective front wheel (532L, 532R) pivots, when making a turn.

Rear wheel assembly 570 (see for example Figs. 22, 23 and 25) includes a rear wheel 572 rotatable connected to a rear shaft. Rear wheel assembly 570 may further include a rear-wheel cover 574. Rear wheel assembly 570 may be operated by a rear wheel motor, such as, with no limitations, an electric motor (not shown) powered for example by a battery 999 (see, for example Figs. 26b, 36c). Rear-wheel cover 574 may also serve as a brake mechanism or a part thereof. It should be appreciated that the wheel motor may be configured to drive the scooter apparatus either forward or backwards or both forward and backwards.

Fig. 26a is a front partial view of scooter 500, schematically illustrating a nonlimiting example of steering mechanism 530, wherein for visibility purposes only, some parts (related to steering post 510) have been removed for illustration purposes only, and wherein scooter 500, is shown in a deployed position (state). Similarly, Fig. 27a is a front view of the scooter 500, schematically illustrating steering mechanism 530, wherein for visibility purposes only, some occluding parts have been removed for illustration purposes only, and wherein scooter 500 is shown in a left turn instance position.

Fig. 26b is a front view, schematic illustration of steering mechanism 530 of the scooter 500, shown in a deployed position. Fig. 26b illustrates components that take part in facilitating scooter 500 to turn either left or right. Similarly, Fig. 27b is a front view, schematic illustration of the steering mechanism 530 of the scooter 500, shown in a left turn instance position. Fig. 27b illustrates components that take part in facilitating scooter 500 to turn (left turn in the non-limiting example shown in Fig. 27b).

The steering mechanism 530 components that take part in facilitating scooter 500 to turn, with automatic tilt of the steering post 510, include steering post 510, a pair of front wheels 532, a tilt-synchronizing unit 540 and a pair of balancing-actuators 592 (592UP, 592LW), shown as a pair of springs, by way of example only. Balancing-actuators 592 may also be embodied, for example, as a pair of pneumatic or hydraulic mechanisms. The steering mechanism 530 further includes the following interfacing components: a pivotal-interface unit 560 a tilt-conveyor unit 590, and a non-pivotal-frame element 580.

It should be appreciated that while the rider pivots steering post 510, pivotal- interface unit 560, being securely attached to steering post 510, pivots along with steering post 510, while tilt-conveyor unit 590, being pivotally connected to non-pivotal-frame element 580 at bearing 585, tilts sideways in sync with the pivotal motion of steering post 510

The pair of similar balancing-actuators 592 (592UP, 592LW) are mounted on a mutual vertical carrying rod 595 (see for example Fig. 26a), and wherein a pair endstoppers (upper end-stopper 591UP, and lower end-stopper 591LW) limit the motion of balancing-actuators (592UP, 592LW) disposed there between the end-stoppers (591UP, 591LW) on vertical carrying rod 595, having an upper open end and a lower open end (see for example Figs. 27a and 27b). When a balancing-actuator (592UP, 592LW) is pressed (or extended) by an external force balancing-actuator (592UP, 592LW) the external force is stored there inside, wherein the balancing-actuator (592UP, 592LW) uses stored force to try and return to its idle state. The balancing-actuators 592UP and 592LW are separated by a force conveying ring 594 disposed therebetween, and wherein the force conveying ring 594 receives a forceful motion vector along vertical carrying rod 595 and towards either balancing-actuators 592UP or 592LW, from tilt-conveyor unit 590 that is securely attached to the steering post 510 and is configured to pivot about a bearing 585 disposed at a laterally central location of non-pivotal-frame element 580. When no tilt is asserted onto steering post 510, force conveying ring 594 applies equal pressing force onto both balancing-actuators 592 (592UP, 592LW).

It should be appreciated that the respective position of upper end-stopper 591UP and lower end-stopper 591LW, may be adjusted, for example by a respective nut 593UP or 593LW (see for example Figs. 27a and 27b).

The force conveying ring 594 is securely and operatively connected to the tiltconveyor unit 590. Hence, force conveying ring 594 actuates the relative rotational power forces between non-pivotal-frame element 580 and the respective balancing-actuator 592 (592UP and/or 592LW), and asserting a steering-post-return-force counter to the pivotal force applied by the driver on the steering post 510. Once the driver weakens or releases the pivotal force (or turns back the steering post 510), the balancing-actuators 592 assert a counter force onto force conveying ring 594 that cause the steering post 510 to pivot towards a straight, upright position of steering post 510. It should be appreciated that balancing-actuators 592 may store a biasing force by either compressing a compressible balancing-actuators 592, or by pulling a balancing-actuators 592. The present disclosure is described as if a respective balancing-actuator 592 is compressed, and the stored biasing force within the respective balancing-actuator 592 tries to return to its idle, noncompressed state (or a balance compression state between both balancing-actuators 592UP and 592LW)

It should be further appreciated that standing board 521, also being attached to tilt-conveyor unit 590, is configured to incline sideways towards the inside periphery of the turning curve, together with tilt-conveyor unit 590 (for example, see Figs. 27a and 27b as well as a scooter-folding-interface assembly 600 shown, for example, in Fig. 28a below).

Figs. 28a and 28b are provided to further clarify the steering mechanism 530 and the inter-relation between pivotal-interface unit 560, tilt-synchronizing unit 540, tiltconveyor unit 590 and non-pivotal-frame element 580. Fig. 28a is a rear elevated perspective view illustration of the steering mechanism 530 components while scooter 500 is in a left turn instance position, and Fig. 28b is a front elevated perspective view illustration of the same. Together, the tilt-synchronizing unit 540 and a truncated rotatingcone 542, facilitate automatic tilt of the steering post 510, when pivoting steering post 510 (to the left, in the shown non-limiting example).

The non-pivotal-frame element 580 includes a tilt-synchronizing-unit-holding- ring 582 that is configured to affix the tilt-synchronizing unit 540 to non-pivotal-frame element 580. The pivotal-interface unit 560, on the other hand, is affixed to steering post 510, and thereby pivots with the steering post 510, when steering post 510 is pivoted by the rider or otherwise. Fig. 28c is a rear, vertical cross-section view illustration of a portion of the steering mechanism 530 components, wherein steering post 510 is in an upright position.

Reference is also made to Fig. 29a that illustrates a front, top perspective view of tilt-synchronizing unit 540, and to Fig. 29b that illustrates a front, bottom perspective view of tilt-synchronizing unit 540. Tilt-synchronizing unit 540 includes two parallel arched shaped deep ribs: top arched-rib 544 and bottom arched-rib 546. Reference is also made to Fig. 29c that illustrates a side view of tilt-synchronizing unit 540, facing top arched-rib 544 and bottom arched-rib 546. Each arched-rib (544 and 546) has a respective inner flat face (543 and 547) that is laterally slopped inwardly, wherein the intemal- arched-gap Din is wider than the external-arched-gap D _ex t, remaining operatively even along the full operative length of both arched-ribs (544 and 546).

It should be appreciated that when steering post 510 is in an upright position, the pair of arched-rib (544 and 546) has an initial inclination angle with respect to the horizon.

Reference is also made to Fig. 29d that illustrates a front, vertical cross-section view of tilt-synchronizing unit 540, wherein a truncated rotating-cone 542 is disposed there between top arched-rib 544 and bottom arched-rib 546. The sloped periphery 548 of truncated rotating-cone 542 and those of the inner flat faces (543 and 547) are operatively of the same angle y, allowing truncated rotating-cone 542 to freely and fittingly, roll there inside the internal space formed between the inner flat faces (543 and 547), from one end of one inner flat face (543 or 547) of the respective arched-rib (544 and 546) to the other end of the inner flat face (543 or 547) of the respective arched-rib (544 and 546).

Reference is also made to Fig. 29e, illustrating a front, lateral cross-section view of tilt-synchronizing unit 540. Fig. 29f, illustrates a top view, of the cross-section shown in Fig. 29e, wherein the arched inner flat face 547 of arched-rib 546 is fully shown, and wherein arched-rib 546 (implying also to arched-rib 544) is shown to be part of an imaginary cylindrical ring 539 having a depth W2 and a transverse axis that operatively coincides with pivotal axis 515 of steering post 510.

It should be appreciated that when the steering post 510 is in and upright position, the truncated rotating-cone 542 is disposed between the top arched-rib 544 and the bottom arched-rib 546, at (or proximal to) the center of the inner flat faces (543 and 547). Fig. 30a illustrates a top perspective view of tilt-synchronizing unit 540, wherein truncated rotating-cone 542 is disposed between the top arched-rib 544 and the bottom arched-rib 546, at (or proximal to) the center of the inner flat faces (543 and 547). Fig. 30b illustrates a bottom perspective view of tilt-synchronizing unit 540 shown in Fig. 30a. Reference is also made to Fig. 30c that illustrates a top perspective view of tilt-synchronizing unit 540, wherein truncated rotating-cone 542 is disposed between the top arched-rib 544 and the bottom arched-rib 546, proximal the front end of the inner flat faces (543 and 547), demonstrating a left turn instance position. Fig. 30d illustrates a bottom perspective view of tilt-synchronizing unit 540 shown in Fig. 30c.

Reference is also made to Fig. 31a that is a front, elevated, perspective view schematic illustration of pivotal-interface unit 560, according to the present disclosure. Pivotal-interface unit 560 includes a post interface section 564 having a rotational axis that coincides with pivotal axis 515 of steering post 510, a pivoting receiving linkage arm 566, a pivoting receiving linkage component 567, a rotating-cone linkage arm 562, and a rotating-cone linkage assembly 561. The rotating-cone linkage assembly 561 includes a stationary shaft 531, wherein truncated rotating-cone 542 is rotatably mounted on the stationary shaft 531, as illustrated in Fig. 31b. Pivoting receiving linkage arm 566 is securely attached to pivotal-interface unit 560, as shown in Fig. 28b.

Fig. 32a is a front and slightly elevated perspective view schematic illustration of tilt-synchronizing unit 540 of steering mechanism 530, the scooter 500 being in a deployed position, wherein steering post 510 is in an upright position, and wherein tiltsynchronizing unit 540 is operatively paired with the truncated rotating-cone 542 that is rotatably mounted on the stationary shaft 531 of rotating-cone linkage assembly 561, of rotating-cone linkage arm 562, of pivotal-interface unit 560. It should be appreciated that since steering post 510 is in an upright position, truncated rotating-cone 542 is disposed between the top arched-rib 544 and the bottom arched-rib 546, at (or proximal to) the center of the inner flat faces (543 and 547).

Fig. 32b is a bottom-front perspective view schematic illustration of a front perspective view schematic illustration of a tilt-synchronizing assembly 555, the assembly 555 including tilt-synchronizing unit 540 of steering mechanism 530, the scooter 500 being in a deployed position, wherein scooter 500 is shown, by way of example, in a left turn instance position. The tilt-synchronizing unit 540 is operatively paired with the truncated rotating-cone 542 that is rotatably mounted on the stationary shaft 531 of rotating-cone linkage assembly 561, of rotating-cone linkage arm 562, of pivotal-interface unit 560. It should be appreciated that since steering post 510 has been pivoted in the example to the left, truncated rotating-cone 542 is disposed between the top arched-rib 544 and the bottom arched-rib 546, proximal the front end of the inner flat faces (543 and 547), demonstrating a left turn instance position. When the rider pivots steering post 510 to the left, truncated rotating-cone 542, being disposed between the top arched-rib 544 and the bottom arched-rib 546, rolls there in between arched-ribs 544 and 546 towards the front end of the inner flat faces (543 and 547), proportionally to the pivoting angle.

It should be appreciated that when making a right turn (in this example embodiment), by pivoting steering post 510 to the right, truncated rotating-cone 542 rolls between arched-ribs 544 and 546 towards the rear end of the inner flat faces (543 and 547).

Tilt-synchronizing unit 540 of steering mechanism 530 may further include a tilt biasing mechanism of steering post 510, as a function of the driving speed of scooter 500, in addition to the degree of pivoting steering post 510. A speed-biasing motor 549 is pivotally attached to tilt-synchronizing unit 540 via a central shaft 541, whose rotational axis 545 (see Figs. 29d and 29e, for example) coincides with the rotational axis of speedbiasing motor 549.

Typically, with no limitations, the tilt degree is preset to a balanced (with no bias) state predesigned for some average riding velocity. If the current speed is higher than that average riding velocity, then speed-biasing motor 549 may be activated to pivot tiltsynchronizing unit 540 to thereby increase the tilt angle of arched-ribs (544 and 546) and the tilt angle of steering post 510; and if the current speed is lower than that average riding velocity, then speed-biasing motor 549 may be activated to pivot tilt-synchronizing unit 540 to thereby decrease the tilt angle of arched-ribs (544 and 546) and the tilt angle of steering post 510.

It should be appreciated that when scooter 500 is in the deployed position, the scooter 500 is in an idle state, including balancing-actuators 592. Balancing-actuators 592, having an initial tension force F), balance each other such that rotating-cone 542 is positioned adjacent to the sloped inner flat faces (543 and 547), at a central section of sloped flat faces (543 and 547), as shown in a non-limiting example in Figs. 29a, 29f, 30a and 30c.

It should be further appreciated that while the scooter 500 is in a turn position, the pivoted front wheels (532L, 532R) remain in an upright orientation, wherein both wheels remain firmly on the road, when riding in reasonable speed. Furthermore, each of the pivoted front wheels (532L, 532R) is configured to pivot about a respective independent shaft 558 turning radius. Referring back to Fig. 27a that illustrates a front view of the scooter 500, wherein scooter 500 is shown in a left turn instance position. It can be clearly seen that while pivotal-interface unit 560 is tilted, along with steering post 510, into the side of the turn, pivotal-interface unit 560 tilts about shaft 585 of non-pivotal-frame element 580, and non-pivotal-frame element 580 remains non-tilted, generally parallel to the ground surface. Thereby, pivoted front wheels (532L, 532R) remain in an upright orientation, wherein both wheels remain firmly on the road, when riding in reasonable speed. Furthermore, each of the pivoted front wheels (532L, 532R) is configured to pivot about a respective independent shaft 558 (see Fig. 25). In order to bring scooter 500 from the idle state to the left turn instance position desired direction, as shown by way of example in Figs. 22 and 23 , (the left turn being a non-limiting example to any desired direction of the driver), the driver of scooter 500 pivots steering post 510 to the left about pivotal axis 515, while applying a pivotal force Fp, typically, by using one or both handle-grips 516. The driver’s pivotal action initiates to following chain of reaction: a. steering post 510 pivots to the left, about pivotal axis 515, against a resisting force Fs of balancing-actuators 592. b. tilt-synchronizing unit 540, being securely attached to steering post 510 pivots with steering post 510. c. as tilt-synchronizing unit 540 pivots, inner flat faces (543 and 547) of the arched-ribs (544 and 546, respectively) pivots too, applying friction force FF onto the sloped periphery 548 of truncated rotating-cone 542. d. truncated rotating-cone 542, being mounted on stationary shaft 531 (see Figs. 31a and 31b) that is secured to rotating-cone linkage arm 562, of pivotal- interface unit 560, is free to rotate about stationary shafts 531, while the inner flat faces (543 and 547) roll over the sloped periphery of the freely rotating truncated rotating-cone 542.

It should be appreciated that the group: tilt-synchronizing unit 540, truncated rotating-cone 542 and pivotal-interface unit 560, may be referred to as tiltsynchronizing assembly 555 (see Figs. 26b, 27b, 28b, 32a and 32b).

It should be further appreciated that sloped inner flat faces (543 and 547) roll over the sloped periphery of the freely rotating truncated rotating-cone 542, because of the friction force Fp that exists between the two sloped surfaces. It should be further appreciated that the friction force FF may cause erosion of surfaces of sloped inner flat faces (543 and/or 547), which erosion can be calibrated by a calibration mechanism (for example calibrating-bolt 538, see Fig. 31b) that moves the sloped periphery of the freely rotating truncated rotating-cone 542 along rotational axis 565, while sloped inner flat faces (543 and 547) remains stationary. e. pivotal-interface unit 560, being securely attached to steering post 510, pivots along with steering post 510 about the pivotal axis 515 of steering post 510. Pivotal-interface unit 560 is also securely attached to tilt-conveyor unit 590 that is pivotally connected to non-pivotal-frame element 580 at bearing 585. Thus, as pivotal-interface unit 560 pivots about the pivotal axis 515 of steering post 510, the pivotal motion of pivotal-interface unit 560 is also converted by tilt-conveyor unit 590 into a tilt motion (about bearing 585) of tilt-conveyor unit 590, and also of pivotal-interface unit 560 and of steering post 510.

Hence, steering post 510 tilts sideways in sync with the pivotal motion of steering post 510, and as long as the driver keeps pivoting steering post 510, the pivoting steering post 510 also tilts into the selected pivotal motion side. As steering post 510 continues to tilt, one balancing-actuator 592 (the right balancing-actuator 592LW in this example) increases its tension with respect to initial tension force J), while the other balancing-actuator 592 (the left balancing-actuator 592UP in this example) decreases its tension with respect to initial tension force Fj.

It should be appreciated that the balancing-actuators 592 being unbalanced during while the steering post 510 is tilted, seek to balance their tension forces, and return to their idle state in which state their initial tension force is Fj. therefore, once the driver weakens or releases the pivotal force asserted upon the steering post 510, the balancing-actuators 592 pivots the steering post 510 towards a straight, upright position of steering post 510.

Preferably, scooter 500 includes a folding mechanism facilitating folding scooter 500 to a folded state, such that rear wheel 572 docks between or near the front wheels 532, wherein rear wheel 572 is situated higher that front wheels 532, and wherein scooter 500 can be carried as if it were a carry-on luggage or a trolley carrier.

Fig. 33a is a front perspective view schematic illustration the folded scooter 500, according to embodiments of the present disclosure, the scooter being in a folded state. Folded scooter 500 is shown in an upright position, which is the idle state of scooter 500. Fig. 33b is a rear perspective view of the folded scooter 500, wherein the folding process is facilitated after locking mechanisms of an interfacing-profile-arm 610 of a scooter- folding-interface assembly 600 (shown, for example, in Fig. 34a below) are unlocked. It should be appreciated that the folded components may also be locked in the folded state. It should be appreciated that scooter 500 may further include a utility case 599, configured to be attached to steering post 510, including in a folded state, according to embodiments of the present disclosure. Fig. 33c is a side view of the folded scooter 500 shown in Fig. 33b. It should be appreciated that the folded components may also be locked in the folded state.

Fig. 34a is a rear, elevated, perspective view schematic illustration of a lower portion of scooter 500, according to embodiments of the present disclosure. During the folding process were scooter-folding-interface assembly 600 has been activated, interfacing-profile-arm 610 folds upwardly, pivoting about axis 615, while the front end of deck assembly 520 rises upwardly with respect to the pivotally connected interfacingprofile-arm 610, pivoting about axis 625 (shown, for example, in Fig. 34c below). While folding, rear wheel 572 remains on the ground, but when folding is complete, the rear wheel 572 is situated in the air, facilitating comfort use of front wheels 532 to park the scooter or to carry the scooter as a trolley carrier. The rear lower end of interfacingprofile-arm 610 is pivotally attached to a lower rear-pivotal-joint (620RR see below, for example, with respect to Figs. 34c, 34d, 35a, 35b and 36a), that is securely attached to deck assembly 520, facilitate pivotal motion between interfacing-profile-arm 610 and deck assembly 520. It should be noted that the front upper end of interfacing-profile-arm 610 is pivotally attached to an upper front-revolute-joint (620FR see below, for example, with respect to Figs. 34e, 35a and 36a), that is securely attached to tilt-conveyor unit 590, facilitate pivotal motion between interfacing-profile-arm 610 and steering mechanism 530.

Fig. 34b is a side view schematic illustration of a frontal lower portion of scooter 500, according to embodiments of the present disclosure, wherein the scooter 500 is an upright, deployed balanced state. In the shown state, the front end of deck assembly 520, which is, with no limitations, generally parallel to the road surface, and is interconnected to frontal tilt-conveyor unit 590 (see also Fig. 28a) by interfacing-profile-arm 610, facilitating tilt of the deck assembly 520, while scooter 500 is in a deployed position.

Fig. 34c is a cross-section view of detailed C, illustrating a non-limiting example of a lower, rear locking-pin assembly 630RR of the deck assembly 520, wherein lower locking-pin assembly 630RR is shown in a locked state. Similarly, Fig. 34d is a cross- section view of detailed C, illustrating a non-limiting example of lower, rear locking-pin assembly 630RR of the deck assembly 520, wherein lower, rear locking-pin assembly 630RR is shown in an unlocked state. In this a non-limiting example of a locking mechanism, the locking element is a lower, rear latch-threaded-bolt 638RR (being a deck- locking-pin), that is operatively coupled with a lower section motor 635RR configured to control the lock/unlock state of lower, rear latch-threaded-bolt 638RR by power driving lower, rear latch-threaded-bolt 638RR into and out of a selected receiving cavity (a deployed, rear receiving threaded cavity 621RR or a folded, rear receiving threaded cavity 622RR), using a rotating bold driving element, for example a fitted-driving-socket 632RR that fits the latch-threaded-bolt head. When a vacant receiving cavity faces the end of lower, rear latch-threaded-bolt 638RR, to lock the respective folding joint in position, lower section motor 635RR rotates fitted-driving-cavity 632RR that in turn drives lower, rear latch-threaded-bolt 638RR into that selected receiving thread (deployed, rear receiving cavity 621RR or folded, rear receiving cavity 622RR). Fig. 34e is a vertical crosssection view of a non-limiting example of an upper, front locking mechanism 630FR of the front upper portion scooter-folding-interface assembly 600, in which an upper, front latch-threaded-bolt 638FR (being a post-locking-pin) is locked into folded, front threaded receiving cavity 622FR.

When scooter 500 is in a deployed position, the lower section receiving threaded cavity 621RR is facing the end of lower, rear latch-threaded-bolt 638RR. Thereby, to lock deployed, rear receiving threaded cavity 621RR in the deployed position, lower section motor 635RR rotates fitted-driving-socket 632RR that in turn drives lower, rear latch- threaded-bolt 638RR into the deployed, rear receiving threaded cavity 621RR; and to unlock deployed, rear receiving threaded cavity 621RR, lower section motor 635RR rotates fitted-driving-socket 632RR that in turn drives lower, rear latch-threaded-bolt 638RR out of deployed, rear receiving threaded cavity 621RR. When scooter 500 is in a folded state, the lower section folded, rear receiving threaded cavity 622RR is facing the end of lower, rear latch-threaded-bolt 638RR. Thereby, to lock folded, rear receiving threaded cavity, rear 622RR in the folded state, lower, rear section motor 635RR rotates fitted-drivingsocket 632RR that in turn drives lower, rear latch-threaded-bolt 638RR into that folded, rear receiving threaded cavity 622RR; and to unlock folded, rear receiving threaded cavity 622RR, lower section motor 635RR rotates fitted-driving-socket 632RR that in turn drives lower, rear latch-threaded-bolt 638RR out of folded, rear receiving threaded cavity 622RR. Fig. 35a is a side, vertical, cross-section view schematic illustration of interfacing- profile-arm 610, according to some non-limiting example embodiments of the present disclosure. Interfacing-profile-arm 610 includes the lower locking mechanism 630RR and a similar front locking mechanism 630FR, both are shown in an unlocked state, wherein the respective latch-threaded-bolt (638RR, 638FR) is in an unlocking position (also shown in Fig. 34d). In the example state shown in Fig. 35a, deployed receiving threaded cavities (621RR, 621FR) are shown facing the end of the respective latch-threaded-bolt (638RR, 638FR), while folded receiving threaded cavities (622RR, 622FR) are shown away from the respective latch-threaded-bolt (638RR, 638FR).

Fig. 35b is a side, schematic illustration of the internal elements of interfacingprofile-arm 610, according to some non-limiting example embodiments of the present disclosure, wherein the interfacing-profile 610 has been removed for illustrative purposes only. As revealed in Fig. 35b, both section motors 635RR and 635FR are part of a respective motor-gear assembly (636RR, 636FR), which assemblies may further include a respective gear (637RR, 637FR).

Fig. 35a further illustrates lower section motor 635RR and front section motor 635FR, each interfaced with the respective fitted-driving-socket (632RR, 632FR), wherein the respective bolt-head (631RR, 631FR) is accommodated there inside the respective fitted-driving-socket (632RR, 632FR). Hence, in example embodiment shown, the front motor-gear assembly 636FR and a lower motor-gear assembly 636RR are interfaced with the respective fitted-driving-socket (632RR, 632FR). In the example unlocked state shown in Figs. 34d and 35a, when a selected motor-gear assembly (636RR and/or 636FR) is activated, the respective fitted-driving-socket (632RR, 632FR) is rotated, to thereby drive the respective latch-threaded-bolt (638RR, 638FR) into the respective deployed receiving threaded cavity (621RR, 621FR).

Fig. 22, for example, illustrates scooter 500 in a deployed position, wherein typically, in a deployed position, the rear, lower locking mechanism 630RR is preferably in a locked state (see Fig. 34c), wherein lower, rear latch-threaded-bolt 638RR is locked in deployed, rear receiving threaded cavity 621RR; and the front locking mechanism 630FR is preferably in a locked state, wherein front, upper latch-threaded-bolt 638FR is locked in deployed, front receiving threaded cavity 621FR. The folding of scooter 500 is preferably, with no limitations, may be a fully automatic. Reference is also made to Fig. 36a that illustrates the scooter-folding-interface assembly 600, wherein scooter 500 is in a deployed position, including a folding motor 640. Fig. 36b illustrates the scooter-folding-interface assembly 600 shown in Fig. 36a, wherein the folding motor 640 has been removed for illustration purposes only.

The transformation of scooter 500 from a deployed position (see Fig. 22) to a folded state (see Fig. 33c) and from a folded state to a deployed position, typically includes two basic motions: 1) the motion of the scooter-folding-interface assembly 600 towards steering post 510 and back; 2) the motion of the deck assembly 520 towards the scooter-folding-interface assembly 600 and back. The paths these two elements perform simultaneously are not the same and not equal: the motion performed by the deck assembly 520 towards the scooter-folding-interface assembly 600 and back is longer than the motion performed by the scooter-folding-interface assembly 600. The methodology of transforming of scooter 500 from a deployed position to a folded state and from a folded state to a deployed position, is configured to synchronize the motions of these two elements.

The folding and unfolding mechanism described in the present disclosure, with respect to scooter 500, further includes an upper front-pivotal-joint 620FR, a lower rear- pivotal-joint 620RR, and a non-elastic tension-cable (or belt) 650 that is wrapped over a pair of cable-wheels: a (see for example Figs. 36a and 36b)a pivotal rear cable-wheel 654. Tension-cable 650 is anchored to front cable-wheel 652 by a front-anchor element 651 and to rear cable-wheel 654 by a lower anchor element 653. Each pivotal -joint 620 (620FR, 620RR) includes a shaft-holding-hinge-device 628 (628FR, 628RR) and a ring (or bearing) element 624 (624FR, 624RR). It should be appreciated that tension-cable 650 can be replaced by a timing belt or a chain coupled with a pair of cog-wheels.

Fig. 36c is a rear, bottom perspective view illustration of the interconnectivity of scooter-folding-interface assembly 600 and other units of scooter 500, according to aspects of the present invention. Fig. 36d is a rear cross-section DD’ (see Fig. 36a) view of lower rear-pivotal-joint 620RR, wherein lower rear-pivotal-joint 620RR includes rear shaft-holding-hinge-device 628RR and rear ring element 624RR. Fig. 36e is a perspective view illustration of shaft-holding-hinge-device 628RR. Shaft-holding-hinge-device 628RR includes an attachment-body 626RR configured to be securely attached to the rear lower end of interfacing-profile-arm 610 by a rear joint interface element 634RR. Rear joint interface element 634RR is also configured to accommodate lower, rear latch-threaded- bolt 638RR and fitted-driving-socket 632RR (see for example Figs. 36a, 36b). Shaft- holding-hinge-device 628RR further includes a pair of rear hinge-walls (627RR and 629RR), wherein a rear hinge-shaft 623RR is secure therebetween. Similarly, front shaft- holding-hinge-device 628FR includes an attachment-body 626FR configured to be securely attached to the front upper end of interfacing-profile-arm 610 by a front joint interface element 634FR. Front joint interface element 634FR is also configured to accommodate upper, front latch-threaded-bolt 638FR and fitted-driving-socket 632FR (see for example Figs. 36a, 36b). Shaft-holding-hinge-device 628FR further includes a pair of front hingewalls (627FR and 629FR), wherein a front hinge-shaft 623FR is secure therebetween.

Since, while folding or unfolding, the motion path that the scooter-folding- interface assembly 600 performs simultaneously towards steering post 510, and the motion path that the deck assembly 520 performs towards the scooter-folding-interface assembly 600 are not of equal diameter, rear cable-wheel 654 is of smaller diameter than the diameter of front cable-wheel 652 by a ratio that brings motion path of the scooter- folding-interface assembly 600 and the deck assembly 520 to a preconfigured simultaneous rest state.

Tension-cable 650 is stretched between the pivotal rear cable-wheel 654 and the stationary front cable-wheel 652, building a tension r, wherein tension-cable 650 is anchored onto both cable-wheels, respectively, such that tension-cable 650 does not slip over either cable-wheel (652, 654) but rather wraps thereover, respectively. When folding or unfolding scooter 500, both moving elements (scooter-folding-interface assembly 600 towards steering post 510 or away therefrom) will start and finish their respective motion simultaneously, since the non-elastic tension-cable 650 remains stretched.

According to variations of the present disclosure, the inner locking mechanism of may be implemented using various locking/unlocking mechanisms known in the art. Another locking/unlocking mechanism of interfacing-profile-arm 610. Reference in now made to Figs. 37a-37c. Fig. 37a is a side, vertical, cross-section view schematic illustration of an interfacing-profile-arm 611, according to some non-limiting example embodiments of the present disclosure. Interfacing-profile-arm 611 includes a lower, rear locking-pin mechanism 670RR and a similar upper, front locking-pin mechanism 670FR of steering post 510, both are shown in an unlocked state, wherein the respective latchbolt (678RR (being a deck-locking-pin), 678FR (being a post-locking-pin)) is in an unlocking position. In the example state shown in Fig. 37a, deployed receiving-cavities (661RR, 661FR) are shown facing the end of the respective locking-ends (671RR, 671FR) of latch-bolts (678RR, 678FR), while folded receiving-cavities (662RR, 662FR) are shown away from the respective latch-bolts (678RR, 678FR). Locking-ends (671RR, 671FR) are fittingly housed inside the respective locking-pin-housing (672RR, 672FR), that direct the respective locking-ends (671RR, 671FR) into and out of the respective receiving-cavities (662RR, 662FR).

Fig. 37b is a side, schematic illustration of the internal elements of interfacingprofile-arm 611, according to some non-limiting example embodiments of the present disclosure, wherein the interfacing-profile 611 has been removed for illustrative purposes only. As revealed in Fig. 37b, both lower section motor 675RR and upper section motor 675FR are part of a respective motor-gear assembly (676RR, 676FR), which assemblies may further include a respective gear (677RR, 677FR). Each motor-gear assembly (676RR, 676FR) is configured the rotate the respective latch-bolt (678RR, 678FR), to thereby either drive the respective latch-bolt (678RR, 678FR) into the receiving-cavities (661RR/662RR, 661FR/662FR), to thereby lock them, or drive the respective latch-bolt (678RR, 678FR) out of the receiving-cavities (661RR/662RR, 661FR/662FR), to thereby unlock them.

Fig. 37c is a vertical cross-section view of a non-limiting example of a front, upper locking-pin mechanism 670UP of the upper portion scooter-folding-interface assembly 600, in which upper locking-end 671UP of latch-bolt 678UP is locked into folded receiving cavity 661UP.

Figs. 37a-37b further illustrate a respective example spring (679RR, 679FR), being a biasing force that pushes locking-ends (671RR, 671FR) of latch-bolts (678RR, 678FR) into the respective receiving-cavity (661RR/662RR, 661FR/662FR).

Fig. 38a is a side view illustration of scooter 500 in a deployed position; Fig. 38b is a side view illustration of scooter 500 in an initial folding instance; Fig. 38c is a side view illustration of scooter 500 in an intermediate folding; Fig. 38d is a side view illustration of scooter 500 in an intermediate folding instance; Fig. 38e is a rear perspective view illustration of scooter 500 in a folded state; and Fig. 38f is a front perspective view illustration of scooter 500 in a folded state. The folding of scooter 500 may be a fully automatic, with no limitations. Reference is also made to Fig. 36a that illustrates the scooter-folding-interface assembly 600 wherein scooter 500 is in a deployed position, including a folding motor 640. Fig. 36b illustrates the scooter-folding-interface assembly 600 shown in Fig. 36a, wherein the folding motor 640 has been removed for illustration purposes only.

It should be appreciated that although the folding motor 640 is shown attached to deck assembly 520, folding motor 640 may be secured to other locations along tensioncable 650.

It should be further appreciated that the folding of scooter may also be fully or partially manual, as will be described further below.

Fig. 39a is a front, side perspective view schematic illustration of the interface of the rear cable-wheel 654 and folding motor 640, according to some non-limiting example embodiments of the present disclosure, wherein folding motor 640 is configured to power pivot cable-wheel 654 via a rear-wheel shaft 645, to thereby wrap or unwrap a portion of tension-cable 650 over or off rear cable-wheel 654. Fig. 39b is a rear, side, partial crosssection perspective view schematic illustration of the interface of the rear cable-wheel 654 and folding motor 640, wherein various elements have been removed for illustration purposes only. Fig. 39c is a rear, elevated perspective view schematic illustration of the interface of the lower rear-pivotal-joint 620RR, including folding motor 640.

After the scooter-folding-interface assembly 600 is unlocked by driving lower latch-threaded-bolt 638RR out of the selected receiving threaded cavity (lower deployed receiving threaded cavity 621RR or folded receiving threaded cavity 622RR), and driving front latch-threaded-bolt 638FR out of the selected receiving threaded cavity (front deployed, front receiving threaded cavity 621FR or folded, front receiving threaded cavity 622FR), an automatic fol ding/unfol ding process can take place. For example, in a deployed position, lower, rear latch-threaded-bolt 638RR is driven out of the lower deployed, rear receiving threaded cavity 621RR and front latch-threaded-bolt 638FR is driven out of the front deployed, front receiving threaded cavity 621FR. Then, the automatic folding/unfolding process may be activated by activating the folding motor 640

As described hereabove, folding motor 640 is configured to power pivot cablewheel 654 via rear-wheel shaft 645, rear cable-wheel 654 being secured to rear-wheel shaft 645. Since rear-pivotal -joint 620RR and front-pivotal -joint 620FR have been unlocked, rear ring element 624RR is free to pivot, with respect to shaft-holding element 628RR, about axis 655. Hence, once folding motor 640 is activated, rear cable-wheel 654 is pivoted and tension-cable 650, being anchored onto rear cable-wheel 654, begins to wrap about rear cable-wheel 654 and thereby inflicts tension onto tension-cable 650. The built tension of tension-cable 650 is transferred to lower rear-pivotal-joint 620RR, and since rear ring element 624RR is free to pivot with respect to shaft-holding element 628RR, and front ring element 624FR is free to pivot about axis 656, with respect to shaft-holding element 628FR. Front ring element 624FR, being secured to a tilt-conveyor unit 590, remains in position, while the front end of interfacing-profile-arm 610, being secured to front hinge-walls (627FR and 629FR, see Fig. 36a) pivots via front hinge-shaft 623FR inside front ring element 624FR.

Thereby, the folding process begins: the front end of standing board 521, being secured to rear ring elements 624RR, begins to incline upwards and forward towards steering post 510 (see Figs. 36a, 36b, path-curve 618), along with the rear end of interfacing-profile-arm 610.

Rear-wheel cover 574 of scooter 500 may also serve as a kickstand. Fig. 40a illustrates an example rear-wheel cover 574, in a perspective, slightly elevated view. Fig. 40b is a side view illustration of the example rear-wheel cover 574. Referring is now made to Fig. 40c, scooter 500 is illustrated in a side view, wherein scooter 500 is shown in an instance just before a folding process is completed, and wherein rear wheel 572 is still situated on the surface of a road 50. Referring is also made to Fig. 40d, where the scooter 500 shown in Fig. 40c has just reached the end of the folding process is completed, and wherein rear wheel 572 is preferably in the air, above the ground level, and scooter 500 leans back on rear-wheel cover 574 that now serves as a kickstand.

It should be appreciated that since scooter 500 includes at least two front wheels 532, scooter 500 is capable of standing still without any support. Thereby, it is also possible to facilitate scooter 500 to drive autonomously. Scooter 500 may be equipped with sensors such as, with no limitation, camera, GPS, a controller, means for remote communication, etc., and thereby enable operation using remote communication.

Reference is now made to Fig. 41a, showing elements of a non-limiting example embodiment of an autonomous driving mechanism 680 that includes an autonomous motor 682 disposed inside the upper-post 512 of steering post 510, a rotation- transmission-rod 684 and a rotation-receiving-rod 686 that is secured to lower-post 514, wherein rotation-transmission-rod 684 and rotation-receiving-rod 686 are operationally disengaged. Fig. 41b is a rear, cross-section view of the autonomous driving mechanism 680 shown in Fig. 41a. Fig. 41c is a rearview illustration of autonomous driving mechanism 680, wherein rotation-transmission-rod 684 and rotation-receiving-rod 686 are operationally engaged. Fig. 41d is a rear, cross-section view of the autonomous driving mechanism 680 shown in Fig. 41c.

Hence, in this example embodiment, in order to activate driving mechanism 680, the upper-post 512 is moved downwards over (or inside) lower-post 514, until rotation- transmission-rod 684 engages with rotation-receiving-rod 686, for example, when a tip 685 at the lower end of rotation-transmission-rod 684 is secured inside a receiving opening formed at the upper end of rotation-receiving-rod 686. Then, when activating autonomous motor 682, rotation-transmission-rod 684, being rotational connected to rotation-transmission-rod 684, begins to pivot in a selected direction; rotation-receiving- rod 686, being secured to rotation-transmission-rod 684, pivots with rotation- transmission-rod 684. Since rotation-receiving-rod 686 is secured to lower-post 514, steering post 510 pivots with rotation-receiving-rod 686. To disengage the autonomous driving, the drive can simply lift the upper-post 512.

It should be appreciated that by using sensors such as, with no limitation, a camera unit and a GPS, and by remote controlling a scooter motor that is coupled with the rear wheel 572, scooter 500 can be remotely driven in any direction, deliver goods, engage with a battery charging unit, and a variety of other tasks.

According to variations of the present disclosure, Figs. 42a and 42b schematically illustrates a third, non-limiting example embodiment of a scooter 700 and a scooter 701, including a steering post 710, a deck assembly 720 having a standing board 721 and a rear wheel assembly 770, a steering mechanism 730 and an optional detachable bag 799, according to aspects of the present disclosure, wherein the steering post 710 is in straight, upright position. Standing board 721 is configured to incline sideways towards the inside periphery of the turning curve, and configured for supporting a rider, typically standing thereon. It should be noted that scooter 700 differs from scooter 701 in that that the scooter 700 includes a motorized folding mechanism and scooter 701 includes a manual folding mechanism. Otherwise, scooter 700 and scooter 701 are identical. Therefore, when referring to mechanisms that do not involve the folding mechanism, the description related to scooter 700 also applies to scooter 701.

Scooter 700 (and scooter 701) is similar to scooter 500, but in particular (with no limitations), scooter 700 differs from scooter 500 in the implementation of the following mechanisms: a steering mechanism 730 compared with steering mechanism 530; a tiltsynchronizing unit 740 compared with tilt-synchronizing unit 540; a tilt-synchronizing assembly 755 compared with tilt-synchronizing assembly 555; a pivotal-interface unit 760 compared with pivotal-interface unit 560; and a tilt-conveyor unit 790 compared with tilt-conveyor unit 590.

Scooter 700 is illustrated in Figs. 42a - 54d which are respectively similar (with no limitations) to Figs. 22 - 41d of scooter 500. The following describes the variations in the embodiment of scooter 700 compared, respectively, with the embodiment of scooter 500.

Reference is made to Figs. 42a - 52d that relate to steering mechanism 730. Steering mechanism 730 facilitates the rider, when turning steering post 710 to turn scooter 700 either to the left or to the right, at his will. Fig. 42b schematically illustrates the scooter 700 in a state where the steering post 710 is pivoted to the left, in direction 717, and thereby also tilted to the left, according to aspects of the present disclosure. Fig. 43 is a rear perspective view, schematic illustration of the scooter 701, according to aspects of the present disclosure, wherein the steering post 710 is pivoted to the left and thereby also tilted to the left. The tilting measure dictates the tilting measure at a constant preconfigured rate. In one embodiment, steering post 710 is subdivided into an upperpost 712 and a lower-post 714, wherein upper-post 712 may slide over lower-post 714, telescopically.

Steering mechanism 730 further includes a pair of front wheels 732 interconnected by a steering mechanism to steering post 710, wherein when steering post 710 is pivoted, each of the front wheels (732L, 732R is also pivoted in the same direction by a wheel s-pivoting-mechanism 750, as shown in Fig. 44. Fig. 44 is a top perspective view, schematic illustration of the front section of the scooter 701, according to aspects of the present disclosure, wherein the non-limiting example shown for the wheels- pivoting-mechanism 750 is based on the Ackerman Steering Principle (ASP). In such an ASP steering mechanism, the inner front wheel needs to turn at a different angle than the outer wheel because they are turning on different radii. The ASP steering mechanism is a geometric arrangement of linkage components (such as 767, 752, 754, 756) in wheels- pivoting-mechanism 750 designed to turn the inner and outer wheels at the appropriate angles. Any other mechanism known in the art for coordinately pivot both front wheels, such as in cars, may be used (and not as, for example, in a “carriage” mechanism). The example wheel s-pivoting-mechanism 750 includes pivoting receiving linkage components 756, receiving the pivotal motion from steering post 710, whereas the motion is transmitted to front wheels 732L and 732R, by a pair of axially moving rods, 752 and 754, to respective linkage components 756, to which respective linkage component 756 the respective front wheel 732 is rotatably attached. It should be appreciated that while the scooter 700 is in a turn instance position, the pivoted front wheels (732L, 732R) remain in an upright orientation, wherein both wheels remain firmly on the road, when riding in reasonable speed. Each linkage components 756 (756L, 756R) further include a respective independent shaft 758 (758L, 758R), about which shaft 758 the respective front wheel (732L, 732R) pivots, when making a turn.

Fig. 45a is a front partial view of scooter 700/701, schematically illustrating a non-limiting example of steering mechanism 730, wherein for visibility purposes only, some parts (related to steering post 710) have been removed for illustration purposes only, and wherein scooter 700, is shown in a deployed position (state). Similarly, Fig. 46a is a front view of the scooter 700, schematically illustrating steering mechanism 730, wherein for visibility purposes only, some occluding parts have been removed for illustration purposes only, and wherein scooter 700 is shown in a left turn instance position.

Fig. 45b is a front view, schematic illustration of steering mechanism 730 of the scooter 700/701, shown in a deployed position. Fig. 45b illustrates components that take part in facilitating scooter 700/701 to turn either left or right. Similarly, Fig. 46b is a front view, schematic illustration of the steering mechanism 730 of the scooter 700/701, shown in a left turn instance position. Fig. 46b illustrates components that take part in facilitating scooter 700/701 to turn (left turn in the non-limiting example shown in Fig. 46b). The steering mechanism 730 components that take part in facilitating scooter 700/701 to turn, with automatic tilt of the steering post 710, include steering post 710, a pair of front wheels 732, a tilt-synchronizing unit 740 and a pair of balancing-actuators 792 (792UP, 792LW), shown as a pair of springs, by way of example only. Balancingactuators 792 may also be embodied, for example, as a pair of pneumatic or hydraulic mechanisms. The steering mechanism 730 further includes the following interfacing components: a pivotal-interface unit 760 a tilt-conveyor unit 790, and a non-pivotal-frame element 780.

It should be appreciated that while the rider pivots steering post 710, pivotal- interface unit 760, being securely attached to steering post 710, pivots along with steering post 710, while tilt-conveyor unit 790, being pivotally connected to non-pivotal-frame element 780 at bearing 785, tilts sideways in sync with the pivotal motion of steering post 710

The pair of similar balancing-actuators 792 (792UP, 792LW) are mounted on a mutual vertical carrying rod 795 (see for example Fig. 45a), and wherein a pair endstoppers (upper end-stopper 791UP, and lower end-stopper 791LW) limit the motion of balancing-actuators (792UP, 792LW) disposed therebetween the end-stoppers (791UP, 791LW) on vertical carrying rod 795, having an upper open end and a lower open end (see for example Figs. 46a and 46b). The balancing-actuators 792UP and 792LW are separated by a force conveying ring 794 disposed therebetween, and wherein the force conveying ring 794 receives a forceful motion vector along vertical carrying rod 595 and towards either balancing-actuators 792UP or 792LW, from tilt-conveyor unit 790 that is securely attached to the steering post 710 and is configured to pivot about a bearing 785 disposed at a laterally central location of non-pivotal-frame element 780. When no tilt is asserted onto steering post 710, force conveying ring 794 applies equal pressing force onto both balancing-actuators 792 (792UP, 792LW)

It should be appreciated that the respective position of upper end-stopper 791UP and lower end-stopper 791LW, may be adjusted, for example by a respective nut 793UP or 793LW (see for example Figs. 46a and 46b).

The force conveying ring 794 is securely and operatively connected to the tiltconveyor unit 790. Hence, force conveying ring 794 actuates the relative rotational power forces between non-pivotal-frame element 780 and the respective balancing-actuator 792 (792UP and/or 792LW), and asserting a steering-post-return-force counter to the pivotal force applied by the driver on the steering post 710. Once the driver weakens or releases the pivotal force (or turns back the steering post 710), the balancing-actuators 792 assert a counter force onto force conveying ring 794 that cause the steering post 710 to pivot towards a straight, upright position of steering post 710. It should be appreciated that balancing-actuators 792 may store a biasing force by either compressing a compressible balancing-actuators 792, or by pulling a balancing-actuators 792. The present disclosure is described as if a respective balancing-actuator 792 is compressed, and the stored biasing force within the respective balancing-actuator 792 tries to return to its idle, noncompressed state (or a balance compression state between both balancing-actuators 792UP and 792LW)

It should be further appreciated that standing board 721, also being attached to tilt-conveyor unit 790, is configured to incline sideways towards the inside periphery of the turning curve, together with tilt-conveyor unit 790 (for example, see Figs. 46a and 46b as well as a scooter-folding-interface assembly 800 shown, for example, in Fig. 47a below).

Figs. 47a and 47b are provided to further clarify the steering mechanism 730 and the inter-relation between pivotal-interface unit 760, tilt-synchronizing unit 740, tiltconveyor unit 790 and non-pivotal-frame element 780. Fig. 47a is a rear elevated perspective view illustration of the steering mechanism 730 components while scooter 700 is in a left turn instance position, and Fig. 47b is a front elevated perspective view illustration of the same. The tilt-synchronizing unit 740 includes a set of four truncated rotating-cones 742, that together with a fitted mountable-arched-rib 744, facilitate automatic tilt of the steering post 710, when pivoting steering post 710 (to the left, in the shown non-limiting example).

The non-pivotal-frame element 780 includes a tilt-synchronizing-unit-holding- ring 782 that is configured to affix the tilt-synchronizing unit 740 to non-pivotal-frame element 780. The pivotal-interface unit 760, on the other hand, is affixed to steering post 710, and thereby pivots with the steering post 710, when steering post 710 is pivoted by the rider or otherwise. Fig. 47c is a rear-view illustration of a portion of the components of steering mechanism 730, wherein steering post 710 is in an upright position. Reference is also made to Fig. 48a that illustrates a front, top perspective view of tilt-synchronizing unit 740, and to Fig. 48b that illustrates a front, bottom perspective view of tilt-synchronizing unit 740. Tilt-synchronizing unit 740 includes, as an example embodiment, four truncated rotating-cones 742 is disposed such that operatively, the wide round side of the truncated rotating-cones 742 face the steering post 710. At the narrow side of the truncated rotating-cones 742 that face away from steering post 710, two truncated rotating-cones 742UP are rotatably disposed at the upper section of tiltsynchronizing unit 740, and the other two truncated rotating-cones 742LW are rotatably disposed at the lower section of tilt-synchronizing unit 740. All of the truncated rotatingcones 742 have the same dimensions, wherein the flat dimension of the cone surface forms an angle y with the rotational axis of the respective truncated rotating-cone 742.

It should be appreciated that in the example embodiment shown with respect to scooter 700/701, the number of the truncated rotating-cones 742 may vary, wherein at least one upper rotating-cone 742UP is used, and at least one lower rotating-cone 742LW is used.

A arched shaped tunnel 747 is formed between the upper truncated rotating-cones 742UP and the lower truncated rotating-cones 742LW Reference is also made to Fig. 48c that illustrates a side view of tilt-synchronizing unit 740, as viewed from the steering post 710. Fig. 48d illustrates a rear, vertical, cross-section view of tilt-synchronizing unit 740. Figs. 48c and 48d illustrates the dimensions of tunnel 747 having a narrow dimension D _ex t and a wide dimension Dm. Fig. 48e illustrates a partial, lateral cross-section, top view of tilt-synchronizing unit 740, showing the front lower truncated rotating-cones 742LW and the rear lower truncated rotating-cones 742LW.

It should be appreciated that when steering post 710 is in an upright position, the tunnel 747 has an initial inclination angle with respect to the horizon. Tilt-synchronizing unit 740 of steering mechanism 730 may further include a speed-biasing motor 749 configured to bias the tilt degree of steering post 710 when making a turn, as a function of the scooter’s 700 riding speed, in addition to the degree of pivoting steering post 710. Speed-biasing motor 749 is pivotally attached to tilt-synchronizing unit 740 via a central shaft 741, whose rotational axis 745 (see Fig. 48e, for example) coincides with the rotational axis of speed-biasing motor 749. Reference is also made to Fig. 49a-49b. Fig. 49a illustrates mountable-arched-rib 744 having an inclined upper flat face 797UP and an inclined lower flat face 797LW, wherein both the inclined upper flat face 797UP and the inclined lower flat face 797LW are inclined by angle y. Fig. 49b, illustrates a top view of the mountable-arched-rib 744, wherein the inclined upper flat face 797UP of mountable-arched-rib 744 is fully shown, and wherein mountable-arched-rib 744 is shown to be part of an imaginary cylindrical ring 739 having a width W3 and a pivotal axis that operatively coincides with pivotal axis 715 of steering post 710.

Reference is also made to Fig. 50a-50c. Fig. 50a illustrates a top perspective view of tilt-synchronizing unit 740, wherein mountable-arched-rib 744 is disposed between the upper pair of truncated rotating-cones 742UP and the lower pair of truncated rotatingcones 742. when scooter 700/701 is in an idle state, mountable-arched-rib 744 has an initial inclination angle with respect to the horizon and situated at (or proximal to) the pivotal axis 745 of mountable-arched-rib 744. Fig. 50b illustrates a vertical cross-section view of the assembly of tilt-synchronizing unit 740 and mountable-arched-rib 744, as shown in Fig. 50a. Fig. 50c illustrates a top perspective view of the assembly of tiltsynchronizing unit 740 and mountable-arched-rib 744, as shown in Fig. 50a, wherein mountable-arched-rib 744 is shown pivoted, to there by facilitate biasing the tilt of steering post 710 according to the speed of driving. The tilt motion is typically performed by an electric speed-biasing motor 749, similar to speed-biasing motor 549 of scooter 500, wherein speed-biasing motor 749 is configured to pivot body 746, onto which truncated rotating-cones 742 are mounted.

Pivotal-interface unit 760 is quite similar to pivotal-interface unit 560, except that the rotating-cone linkage assembly 561 is replaced by an arched-rib linkage assembly 761 that is configured to mount mountable-arched-rib 744, such that mountable-arched-rib 744 will pivot according the any pivotal motion of steering post 710. In one embodiment, the mountable-arched-rib 744 is mounted onto pivotal-interface unit 760 by a calibratingbolt 738 that can be tightened as required via threads of stationary shaft 731, as shown in Fig. 51a.
