FIELD OF THE INVENTION

This invention relates to bicycle parking devices, especially to bicycle parking devices for fixing and holding a bicycle, in particular in vertical position.

DESCRIPTION OF THE RELATED ART

A variety of bicycle parking devices and equipment, such as the widespread horizontal U- shaped bicycle parking stands or hooks on the walls for hanging bicycles, are known and used. These U-shaped stands are inconvenient because bicycles parked in this way occupy a large space that could be used for other purposes. Using bicycle parking when bicycles are hanged on a hook in the wall, it is difficult to lift and move a bicycle, it requires high physical strength, the bicycle may fall, during lifting or lowering bicycles can be damaged, thus this method is not very convenient.

A bicycle parking device for parking several bicycles in vertical position, forming a structure constructed from the column mounted on a platform, and which has a base plate at the top and a lifting unit automatically lifting and lowering the front wheel, with the aid of a screw, coupled with the corresponding nuts, bushings and motor mounted on a base plate, are known (see the description of the invention according to the Patent WO / 2014/184817 published on 20 November 2014).

A shortage of the known bicycle parking device is that the device is for parking several bicycles, therefore it takes up a lot of space, has a complex structure that requires a large amount of various structural elements and a motor which needs electric power sources or other power generation systems.

A bicycle parking device for lifting the bicycle using guides from horizontal position to vertical position, where a device is mounted on the L-shaped vertical wall, with a lifting unit connected to a drive shaft which can be driven by an electric motor, and having a controlled brake system is known (EP 1609708 published on 28 December 2005). A shortage of this bicycle parking device is that the motor, preferably an electric motor is used to lift a bicycle and for the brake system, and therefore power sources and other power generation systems are needed, and this causes the increase in the price of a device, moreover, it requires a special parking place which would be provided with power sources to lift the bicycle, thus its use is limited.

SUMMARY OF THE INVENTION

This invention aims to simplify and cheapen the bicycle parking device with a design to simplify and facilitate the bicycle parking, to expand opportunities for its usability, e.g. to provide a bicycle parking device, which can be positioned and used in different rooms or parking areas, optionally parking the bicycle in any position from horizontal to vertical, depending on the room space, and use of the parking device is simple ensuring parking stability and safety.

The object of the solution is that in the bicycle parking device comprising a stand, trolley mounted in the stand with the possibility to move in it on guides and connected to a lifting unit, a wheel fixing mechanism mounted on the mentioned trolley, where the lifting unit has at least one elastic element connected with one end to the upper part of the stand, and the other end fixed to the trolley, the elastic element is tight when the trolley is in lower position, and when the bicycle is positioned to its initial parking position, its elasticity ensures the lifting of the trolley to upper position, in the lower part of the stand the trolley fixing unit connected with the wheel fixing mechanism which is constructed in the way that when the bicycle is in initial parking position with the wheel placed into a wheel fixing mechanism, fixes the wheel and affects the trolley in such a way that it releases and allows the elastic element to transfer a bicycle with a wheel fixed in a wheel fixing mechanism from initial parking position to rear parking, preferably vertical position by transferring the wheel from rear parking position to initial, preferably horizontal position, the wheel fixing mechanism affects the trolley fixing unit by transferring a trolley to the fixed position and releases the wheel.

Under this invention, a construction of the bicycle parking device with a stand, where the bicycle is lifted to rear, for example, vertical position, with the aid of an elastic element without requiring high human physical strength and power, which is needed for power sources or other fuel-powered energy sources, additional electrical inputs, is proposed and the proposed construction of the device can be mounted in various locations on the wall or to the floor, the balcony railing, parking sites or in different rooms, and also small spaces, such as multi-story apartment house balconies, cellars or garages, and the bicycle parked in any position from horizontal to vertical, depending on the room space.

A wheel fixing mechanism in the bicycle parking device proposed under this invention comprises a base where a wheel holder is mounted in its upper part, the lever is mounted springily on the horizontal axis in the central part and cinematically interacts with a wheel holder and the wheel in such a way that when the wheel is placed in a fixing mechanism, the wheel presses the upper arm of the lever by transferring the lever to the second position where the lever affects a wheel holder, which presses the wheel rim at the spokes from the both sides and the lever has a lever fixer, which fixes the lever in the second position at the same time releasing the trolley fixing unit and allowing the tight elastic element to lift the trolley together with the wheel fixing mechanism mounted on it and a wheel placed in it by transferring a bicycle to rear parking position, preferably to vertical position, and lowering the wheel from rear parking position, preferably vertical position, to initial parking position, preferably horizontal position, a lever fixer interacting with the trolley fixing unit affects the lever by returning it to its initial position where the trolley fixing unit fixes the trolley in the lower position, and the wheel holder releases the wheel, allowing the wheel to displace from the parking device.

Using the proposed wheel fixing mechanism, a wheel rim is fixed at the spokes and the trolley is released and the bicycle is lifted toward rear, for example, vertical position, and when the wheel is lowered to its initial parking position, the trolley is fixed and the wheel is automatically released, and a bicycle parking becomes simple and straight forward, the user does not perform the actions associated with a bicycle fixing, bicycle parking time is reduced, and the stability of the lifted bicycle is ensured.

In the bicycle parking device proposed under this invention, the mentioned wheel holder comprises two side arms pivotally and springily attached to the base of the wheel fixing mechanism placed against each other and cinematically interacting with a the lever in such a way that depending on the position of the lever may press or release the wheel. In the bicycle parking device proposed under this invention, the mentioned side arms of the wheel holder comprises pads, which press the wheel rim at the spokes from the both sides in parking position.

The construction of a wheel support comprising two side arms suits for a various types of wheels with tires of different width. Using pads a wheel rim is more pressed by providing stability for the lifted bicycle, and pads protects from scratches and other types of damage.

A lever fixer in the bicycle parking device proposed under this invention has the lever mounted on an axis and the plate pivotally and springily mounted on it, where when the trolley is in lower fixed position, the mentioned lever connected to a trolley fixing unit fixedly attached to the stand with the aid of a hanging unit when the wheel is placed in the wheel fixing mechanism in initial position, the plate is located perpendicular to the base and rests on it with a free end and fixes the lever in the mentioned second position, the lever disconnects from the trolley fixing unit enabling the trolley to lift to rear parking position and when the trolley is transferred from rear parking position to initial parking position, the plate of the lever fixing unit rests on the trolley fixing unit fixedly attached to the stand, which pushes the plate by turning it and returning the lever to initial position in which the lever releases the wheel holder and the hanging unit of the lever connects with the trolley fixing unit. A wheel is attached to the end of the plate of the lever fixer which rests against the base of the wheel fixing mechanism

In the bicycle parking device, a trolley fixing unit is a hook, and a hanging unit of the lever can be the axis attached to the lever with a space from it or a hole in the lever.

In the bicycle parking device, the approach path and side supports of the wheel are attached to the trolley.

In the bicycle parking device the trolley has wheels which can roll on guides, preferably on rails mounted in the stand.

In the bicycle parking device, an elastic element (4) is optionally at least one rubber or at least one spring. The bicycle parking device proposed under this invention is provided with the trolley stopper mounted on the trolley and is designed as a pedal, one end of which is lifted and the other end rigidly fixes the trolley in its initial position, until the wheel is not placed in a wheel fixing mechanism, and when the wheel is placed in it, it is pressed by the wheel holder and at the same time the wheel presses the mentioned lifted end of the pedal allowing the trolley with the wheel fixing mechanism and the wheel mounted in it to lift to rear parking position.

DESCRIPTION OF THE EMBODIMENT

The bicycle parking device 1 comprises a stand 2, trolley 3 mounted in the stand with the possibility to move in it on guides 4 and connected to the lifting unit 5. The wheel fixing mechanism 6 is mounted on the mentioned trolley 3. The lifting unit 5 is an elastic element, for example, two springs 5 or a rubber connected with the upper end to the upper part of the stand 2, and the other end is fixed to the trolley 3 and the elastic element is tight when the trolley 3 is in lower position. Elasticity of the lifting unit 5 is selected such as to ensure rising of the wheel to rear parking position, which depending on the chosen elasticity of a spring or rubber may be any position from horizontal to vertical position. A trolley fixing unit 7 fixedly mounted in the stand 2 may be a hook 7. The wheel fixing mechanism 6 has the base 8 attached to the trolley 3 where a wheel holder 9 is attached to its upper part; the lever 11 is mounted on the horizontal axis 10 in the central part, which has a lever fixer 12 in the lower part. The lever 11 is provided to interact cinematically with a wheel during the initial bicycle parking, and a wheel holder 9, fixating a wheel. The wheel holder 9 comprises two L- shaped side arms 13, 14 springily and pivotally attached to the base 8 of a wheel fixing mechanism 6 located opposite to each other and connected to the spring 15 and cinematically interacting with a lever 11. The mentioned side arms 13, 14 of the wheel holder 9 have pads 16 which press the wheel rim at the spokes from the both sides during the parking.

The lever fixer 12 comprises an axis 17, which is attached to the lower part of the lever 11, the plate 18, which is mounted on it and is connected to a spring 19 which is tight during the parking. A wheel is attached to the end of the plate 18 which rests against the base 8.

The approach path 20 and side wheel supports 21 are pivotally attached to the front part of the trolley 3. The trolley 3 comprises wheels 22 which can roll on guides 4, preferably on rails mounted in the stand 2.

The lever has the hanging unit 23 which optionally is the axis 17 mounted to the lever with a space or a hole 24 in the lever.

A stopper is mounted on the trolley (3) and designed as a pedal (25) which at one end has rubber pads, which are pressed against the stand in the lower initial position of the trolley when the other end of the pedal is lifted.

DEVICE OPERATING PRINCIPLE

In the case of horizontal parking, the wheel is placed in the wheel fixing mechanism 6 of the bicycle parking device 1. In this way, the front wheel on both sides of the wheel rests on the side supports 21 and stands in horizontal position.

When the bicycle parking position is selected vertically, the wheel is pushed into the wheel fixing mechanism 6 completely until it rests on the pedal 25 and the lever 11 , located in the central part of the wheel fixing mechanism 6. The wheel fixing mechanism 6 is mounted on the trolley 3 in the stand rails 4 and which may move upwards and downwards. The lower part of the trolley 3 and the upper part of the stand are connected by two springs 5. When the wheel fixing mechanism 6 is located in lower position of the device, springs 5 are tight and a wheel fixing mechanism 6 is hang with the hook 7, attached to the lower part of the stand of the bicycle parking device 2 that the fixing mechanism 6 would not lift upwards, optionally through an axis 17 or the hole (24) in the lower part of a lever. Axis 17 is mounted in the lower part of a lever 11 of the wheel fixing mechanism.

When the front wheel is pushed in completely, the wheel presses the pedal 25 having an end with rubber pads which is lifted and releases the trolley. At the same the wheel presses the upper arm of the lever 11 and at the same time the upper arm of the lever presses lower parts of side arms 13, 14 of L-shaped wheel holder 9 located below the lever. Then the upper parts of side arms 13, 14 of the wheel holder 9 move towards each other and stands parallel to the plane of the wheel. Rubber pads 16 located in the upper part of the side arms 13, 14 press the front wheel against both sides at the spokes of the wheel rim and thus fix it. As the lever 11 is mounted on the axis, then when the upper arm of the lever 11 is pressed, the lower arm of the lever lifts, and a plate 18 which is pivotally and springily mounted on the lever fixer and connected to the tight spring 19 is located perpendicular to the base 8 and fixes the lever 11 preventing the lever 11 return to its initial parking position. When the lower arm of the lever lifts, at the same time a hanging unit which is optionally either an axis 17 or the hole in the lever that holds the trolley 3 and a wheel fixing mechanism 6 is uncoupled. The released trolley 3 and a wheel fixing mechanism 6 together with the fixed wheel are lifted upwards by rails 4 with the aid of springs 5. The rear wheel is pushed by hand into the lower part of the stand 2, and the bicycle is placed in vertical position.

When the bicycle is lowered to horizontal position, the bicycle is taken by the saddle and pulled towards you. Because of the weight of the frontal part of the bicycle, a wheel fixing mechanism 6 goes down. When a wheel fixing mechanism 6 goes down, the plate 18 of the lever fixer 12 rest on the hook 7, which with its upper part pushes the plate 18 of the lever fixer 12 by turning it and the lever 11 returns to its initial position with the aid of springs. When the lever 11 returns to initial position, the lower arm goes down and the axis 17 or hole 24 connects with a hook 7 and thus fixes the wheel fixing mechanism 6 and hence the upper part of the lever 11 releases side arms (13, 14) of the wheel holder with rubber pads 16, they also return to its initial position with the aid of springs. The lever 11 pushes the wheel from the wheel holder 9 and the side supports 21 with the aid of springs, and the wheel easily leaves the wheel fixing mechanism 6. Pushed wheel releases the end pressed by a pedal and the other end of the pedal 25 with rubber pads goes down and rests on the stand (2).
