AP3USTIBLE HOLDER FOR MOTORCYCLES 1. AREA OF APPLICATION According to the International Patent Classification, the Invention is classifiable as follows: B62H 3/04 - Separate supports or holders for parking or storing cycles B62H 3/04 - .involving forked supports or brackets for holding a wheel 2. TECHNICAL PROBLEM The technical problem addressed by this Invention is how to design a holder with which it will be possible to: easily lift the rear part of several types of motorcycles having a pedal support on their side, - lift the rear part at an inclination in order to bring the cycle into the best parking position, shift the cycle with its rear part raised, together with the holder, secure the cycle in place, bring the cycle into a position best suited for maintenance and repair works. The defined technical problem has been solved through a holder design proposed in the present Invention. 3. STATE-OF-THE-ART Of known solutions for lifting the rear part, below mentioned are the following two types of holders available on the market: 1. Mountable holder for cycling sport consisting of two bent parallel tubes cross-connected at their ends by means of an element. The bent tube has a larger and a smaller arm which together close an angle smaller than 90 degrees. The cross element regulates the distance between the bent tubes. Weaknesses: - complicated lifting /at the same time you have to hold the cycle with one hand, with the other hand place the hanging-up device in its position and raise the cycle by using leverage. All the time you have to keep the balance, which is not as simple as that considering the weight of the cycle. Indeed, there is a risk for the cyclist to get hurt when trying to prevent the cycle from falling or when it does fall, apart from damage that any such fall may cause to the cycle; - the holder is unstable, because even a slight force applied to the rear part of the cycle /such as giving the cycle a slight push forward/, may cause the cycle to topple; - with the holder the rear part of the cycle is raised only to a certain level, which involves problems in performing repair works on the rear part or other operations on the rear wheel and thus necessitates an extra effort; - the cycle, once lifted, can no longer be relocated or turned around; - safe lifting of the cycle requires two persons. 2. Holder consisting of a sectional 4-wheeled stand and a single-wheeled longitudinal tube. The stand is U-shaped, made of sheet plate, with bent ends directed outwards. Mounted on the bent ends are wheels which raise the stand above the ground level. Weaknesses: - the wheel is mounted on the stand; - due to the small height of the stand's central part from the ground level, resistance is likely to occur in moving the cycle if the surface is uneven or an obstruction, a pebble for example, is encountered; - storing of the cycle is not quite trouble-free, with the tire resting on the stand (not in «midair») - which is rather inconvenient especially in winter when damage is more likely to occur on the tire; - the cycle is slanted, so it is not possible to make full use of the available parking (storing) space. 4. DESCRIPTION OF THE INVENTION The cycle holder, according to this Invention, consists of a stand and a cycle lifting mechanism. The design of the Invention enables jack-type hoisting of the cycle's rear part, with the following operations being also possible: - moving the cycle in all directions without a risk of causing it to fall, - adjusting the distance between the forks, depending on the width of the cycle's rear part, /applicable to different types of cycles - inclining the cycle as required, - locking the holder wheels, i.e., securing the holder from accidental movement. Lifting of the cycle involves the following operations: - resting the cycle on the pedal support - placing the holder under the rear wheel - adjusting the forks on cycle supports, and - turning the bolts with handles The parts of the holder: 1. stand 10. cycle support 2. wheels 11. nut 3. lever 12. cycle support 4. support 13. axle 5. handle-fitted bolt 14. fork 6. bearing 15. rest 7. nut 16. axle 8. plate 17. cycle support 9. sleeve The cycle holder in the present design version is shown in the attached sketches as follows: • Dwg. 1 - holder, front view • Dwg. 2 - detail «A», cross-section • Dwg. 3 - detail «B», cross-section • Dwg. 4 - holder without the bolt, top view • Dwg. 5 - detail «C», side view • Dwg. 6 - detail «C», sectional front view With reference to the above drawings, it can be seen that the holder comprises the stand (1) with wheels (2) and the cycle hoisting mechanism. The stand (1) is 85 made of metal tubes bent to form a U-shaped design, wider than the width of the rear part of the cycle. On the lower side of the stand (1) are four wheels (2) of which at least two are fitted with locks. Attached to the stand on the upper side are cycle supports (10) and (17). Cycle supports (10) are made of sheet plate, substantially U-shaped, welded to the stand, with a borehole to receive the 90 plate (8). Cycle supports (17) are tube-shaped, welded to the stand, serving to receive the axles (16) carrying the levers (3). The hoisting mechanism consists of two identical, mutually independent assemblies. The assemblies are set in parallel and are connected to the stand (1). One of these assemblies is described below: It consists of a lever (3), a handle-fitted bolt (5), a nut (11), a plate (8), a 95 sleeve (9), a bearing (10), a nut (7) and a support (4). The lever (3) has two parallel arms made of sheet plate. Welded to them are the cycle supports (12) and the rest (15). The rest (15) connects the arms into a whole. The arms have boreholes on their upper and lower parts. Through the boreholes on the lower part passes the axle (16), around which moves the lever (3), whereas through 100 the boreholes on the upper part moves the axle (13) which enables the movement of the support (4). The axle (16) is seated in the cycle support (17). Cycle supports (12), made of sheet plate, have boreholes for fixing the nut (11). Through the nut (11) passes the handle-fitted bolt (5). The body of the handle- fitted bolt (5), which almost along its whole length contains a self-locking 105 threading, has a narrowing on the lower part ending in the threading to which the nut (7) is attached preventing the bolt from slipping out. The bolt (5), through the sleeve (9) and the bearing (6), leans on the plate (8). The plate (8), accommodated in the cycle support (10), has a mid-point borehole. By applying manual force on the handle-fitted bolt (5), the lever (3) is moved together with 110 the support (4) and the fork (14), which causes the lifting of the rear part of the cycle. The support (4), made of sheet plate, Z-shaped, contains the fork (14) and the axle (13) which is non-detachably connected to the body of the support (4). Via the axle (13) the support leans on the lever (3), and on the rest (15) via the middle part of its body. The axle (13) serves for moving the support (4) in the 115 direction of the lever's transverse axis, whereas the rest (4) restrains it and keeps it in place. Advantages of the proposed design in relation to the existing ones: - the rear wheel is raised above the ground, - easy lifting of cycles having just a pedal support on the side, 120 - it is possible to lift the cycle from a slanted position, which is not possible with other devices, - lifting on either side helps bring the cycle into the best parking position, - the cycle can be moved in all directions, 125 - the lifting and storing operation takes little time, - the holder has wheels which can be locked, so no accidental movement of the cycle can occur, - with the holder it is possible to bring the cycle into optimum position for maintenance and repair works, 130 - versatile, suitable for several types of cycles. The Invention offers a flexible, durable, useful and low-cost device which incorporates essential improvements compared with other products of this kind. To experts it will be obvious that particular components can be provided in different versions (e.g., hydraulics can replace mechanical hoisting), without 135 departing from the scope and essence of the Invention.
