(57) Abstract:The inventive bike made in the form of two-wheeled machine and consists of a frame, steering, seat, spring spring belt driven gear attached to the rim of the rear wheel, pinion, mounted on the shaft above the rear wheel and mating with an asterisk, the rotation mechanism comprising two coils with ratchet, hinge mounted on a shaft, the connecting coil the rope, working the ropes and blocks, through which the cables are missing, two long rods, mounted on a shaft located in front of the frame, to which are attached the ends of the working cables, two pedals, located on the rods, two hand brakes. 8 Il. The invention relates to the technique, namely the rental.Known bike, containing the saddle, handlebars, frame, supported on two wheel drive bike, the frame is equipped with long, curved rods made with the possibility of reciprocation, which has a pedal for movement thereon, a crank with pedals connected by means of a working rope thrown across the blocks associated kinematically through freewheel with TV and mount gears.In Fig. 1 shows a Bicycle, side view; Fig. 2 bike rear view; Fig. 3 pedal on the truck; Fig. 4 the profile of the rod; Fig. 5 - cover in section; Fig. 6 coil with the ratchet flange; Fig. 7 - flange; Fig. 8 circle-wedge.The bike (Fig. 1 and 2) consists of a triangular frame 1, supported on two wheels. In the rear stands the tripod 2, in which three springs relies saddle 3. In the front part of the frame welded shaft 4, which planted a long, curved rods 5. Above the rods rise of the pedal 6, attached to the trolley (Fig. 3) established in the rod (Fig. 4). Another shaft 7 is installed in the plug above the rear wheel so that sitting on it leading gear 8 were linked with a sprocket wheel 9 attached to the wheel rim. At the ends of the shaft, with the sides of the fork, install the coil with the star wheels 10, having at the edges near the ends of the shaft, drives like flanges (Fig. 6). The perimeters of the flanges sawn through four symmetrical tapered groove 11 (Fig. 7), and on the sides of the flanges (Fig. 6) attached to the sides 12. In cells laid metal circles-wedges 13 (Fig. 8) one per cell. On both sides of the coils with the star wheels on the shaft are installed gaskets. The ends of the shaft are attached to the cover 14 that the speaker cable 15, thrown across the blocks 16, which connects the left and right coils in the mechanism of rotation of the shaft. Working cables 17 wound on the reel with star wheels next to the connecting cable in the direction opposite him, cut through the block-coil 18 and are attached to the ends of the rods 19. Bike short. Brakes manual.Description of the operation of the invention.When the cyclist's foot on the pedal 6 last through the truck pushes the connecting rod 5 and at the same time rolls on it (Fig. 1 and 2). End of the connecting rod moves down and the rope through the block-coil 18, which rotates the spool ratchet 10, which started moving in the opposite direction of the cones (Fig. 7), jams slices wedges 13 (Fig. 8) on the cover 14 and, thus, moves together with the shaft 7 and pinion 8. The wheel is rolling. At the same time, the other coil with the ratchet 10, separated from the other by a cap 7 moves in the direction opposite to the shaft direction, winding the cable 17 to its working half and picking up another rod up. When the cyclist's foot on the other pedal, the left and right coil switch roles.On manufacturing techniques offer the bike is no more difficult today. Improving the pedal; more efficient use of the pedals; more efficient use of the power of the cyclist. Bike, containing the saddle, handlebars, frame, supported on two wheel drive bike, the frame has an arched rods made with the possibility of reciprocation, which has a pedal for movement thereon, a crank with pedals by means of the working rope thrown across the blocks, kinematically connected through a freewheel with a sprocket wheel, characterized in that the saddle is installed on the frame by means of a tripod, on which three springs relies saddle, and on the front part of the frame is welded to a shaft that has a long, curved rods, on top of the wheel fork has a drive shaft with a pinion connected with a sprocket wheel attached to the wheel rim, and at the ends of the drive shaft on each side of the fork set freewheel, each of which is made in the form of a coil with the ratchet, it is equipped with additional blocks for connecting the coils with the star wheels to each other through a connecting cable and work cable wound on the reel with star wheels next to the connecting cable in the opposite direction to him, Pere
