The invention relates to vehicles driven by human muscle force.

Known vehicle driven by human muscle force /U.S. Patent N 1653889, 1927/, containing frame set ne end pivotally mounted on one side of the frame and provided with a platform for the feet, flexible rod, one end of which is mounted on the drive lever, hanging his, covering the support pulley, then flexible rod wound on one of the overrunning clutches, pair mounted on a drive axis, and then covering the intermediate pulley is wound in the opposite direction to the second overrunning clutch and covering the second support pulley, a flexible rod mounted on the second drive lever, suspending it.

Known also Drive mechanism with rocking pedal" /application UK N 2044194, 1980/, containing a frame, a driving wheel mounted on the axis of the sleeve type, which has two overrunning clutches mounted with them bevel gears and related third bevel gear and overrunning clutch connected with the swinging pedals flexible rods. Swinging pedals interconnected three bevel gears. And as a variant of the Actuator swing pedals", made a driving wheel mounted on the axis of the sleeve type, which has two overrunning clutches mounted on their ends of the flexible rod, covering the intermediate pulley mounted on a frame.

The disadvantage is characterized by the first vehicle is prokhladnyy moisture overrunning clutch, what causes erratic operation of the device and its rapid wear. Raising both platforms up, the release from the tension of the intermediate pulley and slide flexible rod on the surface of the winding it on the overrunning clutch occurs when moving the device back and this makes possible the falling flexible rod with a pulley or overrunning, tangles and accelerated its deterioration.

The disadvantage "of the Drive mechanism with rocking pedal" are: runout bevel gears as bearing wear overrunning, the difficulty of adjustment and quick disorder, meshing bevel gears mounted on the overrunning clutch, with the third bevel gear, a characteristic noise of bevel gears, their need for constant lubrication, significant power losses on their work, all this contributes to the instability of their work, accelerated wear, difficult maintenance, and lowering the efficiency of the device. The lack of options "of the Drive mechanism with rocking pedal" are: the need to use this option in conjunction with the swinging pedals connected three gears, which have all the disadvantages related to the use of three bevel gears described above.

This task is solved in that in the vehicle driven by human muscle force, containing a frame mounted on it the steering wheel from the steering fork, front and top rear wheels, a pair of actuating levers, each of which is a front end pivotally mounted on one side of the frame and provided with a platform for the feet, a pair of flexible rods, each of which is attached to the drive lever and covering the supporting pulley fixed to the overrunning clutch, pair mounted on a drive axis, and overrunning clutch their ends fastened flexible traction covering the intermediate pulley, mounted on the frame, according to the invention mounted on the frame overrunning clutch to lock the drive axis during movement of the device in reverse.

The application is attached to the chassis overrunning clutches are allowed to block rotation of the drive axis ago, and therefore to exclude the rotation of each overrunning back, raising both drive levers up to lock the spool with both overrunning flexible rod to the intermediate pulley and release it from Flex is ultimately the device is reliable in operation, durable, simplifies its manufacture and maintenance.

The invention is further explained in the description of example with reference to the accompanying drawings, in which:

Fig. 1 depicts a vehicle according to the invention, side view.

Fig. 2 - the same device according to the invention, the view from the top.

The vehicle, driven by human muscle force, according to the invention includes a frame 1 /Fig. 1, 2/, mounted on it, the steering wheel 2 to the steering fork 3, a front wheel 4 and the rear wheels 5, a pair of actuating levers 6, each of which is supplied by the platform 7 feet with an attached flexible shaft 8. Flexible rod 8, to suspend one drive levers 6, covering the supporting pulleys 9, mounted with their ends on the overrunning clutch 10, mounted on the drive axis 11, the flexible rod 12, envelope mounted on the frame 1 intermediate pulley 13 by winding and fixing of its ends to the overrunning clutch 10, and the overrunning clutch 14 fixed to the frame 1 with the opportunity to interact with the drive axle 11.

The proposed vehicle is used as follows.

In the em to another platform 7, while the flexible rod 8 attached to the drive lever 6 around the supporting pulley 9, causes the rotation of the attached overrunning clutch 10, with the drive axle 11 and rear wheels 5, overrunning clutch 10 is wound a flexible rod 12 and around the intermediate pulley 13, is unwound from the second overrunning clutch 10, simultaneously twisting this overrunning clutch 10, attached to it a flexible rod 8 attached to the second drive lever 6, the first lever 6 is raised. Clicking on the second platform 7 of the drive lever 6 and the process repeats.

When moving the device back overrunning clutch 14, mounted on frame 1, blocks rotation of the drive axis 11, thereby does not allow you to cheat on both overrunning clutch 10 flexible rod 8 and unwinding with them flexible rod 12, freeing her intermediate pulley 13.

It should be understood that the above-described exemplary embodiment of the vehicle are given in a purely illustrative purposes and does not limit the invention, which can be made various changes or modifications not beyond its size, which is determined by the proposed formula.

For example, the device may be equipped with a saddle DL is Proposed, the vehicle may find application in transportation engineering, domestic, medical and sports equipment.

The vehicle, driven by human muscle force, containing a frame mounted on it the steering wheel from the steering fork, front wheel, rear wheel, mounted on the drive axis with a pair of overrunning clutches, a pair of actuating levers, each of which is a front end pivotally mounted on one side of the frame and has a platform for the feet, a pair of flexible rods, each of which is attached at one end to the drive lever, the other end of the covering anchor pulley mounted on a frame fixed to the overrunning clutch, the intermediate pulley mounted on the frame, and more flexible traction covering the intermediate pulley, characterized in that it is provided with an additional overrunning clutch, which is mounted on the frame and is intended for fixing the drive axis when reversing.
