The invention relates to transport machinery, namely, rental, driven by human muscle force.

In today's world more and more attention is dropped to the development of environmentally friendly transport modes, which include Transpo, as traditional, environmentally friendly mode of transport, aimed at the present time to expand their scope (tricycle, cargo design, sports wheelchairs, etc), manufacturability, razornet for storage in apartments, increasing the efficiency of human muscle force, improving the weight and size characteristics, finding new efficient schemes drive, etc.

The most interesting of these to create new design concepts of the drive to improve the physical abilities of a person.

Known construction tricycles with lever actuator as foot /1/, manual /2/ in which is used a chain.

Characteristic of these structures is low by modern standards, the percentage usage of the physical capabilities of a person, nerazborite design.

Known construction tricycles with lever actuator as foot /3/, manual /4/ in which is used Krivoshapko-rod mechanisms of transmission to the drive wheels.

The disadvantages of these designs are the increased weight and size of structures and again nedostatocnym lever actuator, as foot and hand, which used human muscle force. In this design significantly deteriorated security (leading star hand chain transfer is in front of the chest and the face of a cyclist), and, most importantly, control of the bike, because the hands, performing two movements, twist pedals and turn, take anatomically not very pleasant for a man of position, causing discomfort and fatigue.

A known construction of a Bicycle /6/ with integrated lever drive pedal and manual, the first of which traditional foot-and-chain transmission, and the second connected to the upper branches of a chain ratchet mechanism with a toothed wheel driven by a rocking lever that is moved by the hand of the cyclist in the longitudinal plane of the Bicycle.

The disadvantage of this design are as in the previous case, with some increase in the utilization of human muscle force, the deterioration of the controllability of the bike (can be controlled with one hand when using the manual drive), increased design complexity due to the presence of a host of manual drive.

A known construction of a Bicycle /7/, select the one drive to transfer forces the cyclist to the drive wheels through a flexible connection.

The movement of the cyclist utrirovannoe movement of the rower on the academic boat, because when the movable seat, moving along the inner pipe legs (the carriage with the feet moving at a constant angle of 45 60oto the trajectory of the bike) the hands of the cyclist hold the wheel in the same position.

Despite the fact that in the security plan for the movement of the rower is one of the most powerful movements of the person on the energy, its constructive embodiment of this bike was not sufficiently successful.

Indeed, at sufficiently wide amplitude of movement of the legs, it is not used powerful pulling back muscles due to the rolling of the hands holding the steering wheel, which almost negates the positive aspects in substantial improvements in the design of the utilization of the physical capabilities of the person.

The task was set by the author in developing the proposed physical abilities of the person using the principle of the motion of the rower as the most powerful on the energy movement, without complication of the structure.

This problem is solved in the proposed design of the bike contains a frame, front controlled the most important drive sprocket, associated with two freewheel clutches closed by a flexible connection including chain Galya around the roller and the cable, due to the fact that in it the foot actuator is made in the form of a lever mounted at one end on the top rail of the frame, with the ability to swing around a horizontal axis in the longitudinal plane of the Bicycle and provided with supports for the legs of a cyclist on the other end, also, a manual actuator in the form of a lever mounted in a tubular guide, the lower end of which is placed with the opportunity to swing in the longitudinal plane of the Bicycle around a horizontal axis mounted on the lower crossbar of the frame, and provided with operating handles in the top and bottom end kinematically, for example, via a cardan suspension and chain transmission connected to the fork of the front wheel, with frame roller closed flexible connection mounted on the horizontal axis, mounted on the front frame, for example, on the sleeve fork of the front wheel, with the possibility of rotation in the longitudinal plane of the Bicycle, and foot-operated lever connected with one branch of a closed flexible links containing chain Galya and the rope thrown over the envelope of the roller, on the first coupling light foot levers and manual actuators are connected to the opposite branches of the second flexible connection to the second freewheel through the ropes and the second circuit Galya.

In addition, to reduce the longitudinal size when transporting the bike, it can be made in the embodiment where the frame it is made of two parts, front and rear, while the front part of the frame, together with a front wheel is mounted to rotate around the axis of the lever actuator clockwise from the operating position to lock the front wheel to the shaft with freewheel clutches, and the upper crossbar of the front frame mounted to rotate on the axis of the roller counterclockwise from the operating position to another in the bottom rail, thus the free end of the upper crossbar of the front frame provided with a hub bearing on the rear part, for example, in the form of the corresponding projection below the neckline in the back of the frame.

Distinctive features of the proposed design are:

running foot drive lever mounted at one end on the top rail of the frame with the ability to swing around a horizontal axis in the longitudinal plane of the Bicycle and provided with supports for the legs of a cyclist on the other end,

introduction to the design manual actuator in the form of a lever mounted in a tubular guide, the lower end of which is and the lower crossbar of the frame and provided with operating handles at the top, and the lower end of kinematically, for example, via a cardan suspension and chain transmission connected to the fork of the front wheel.

installation around the roller closed flexible connection on the front of the frame, for example, on the sleeve fork of the front wheel, for rotation on a horizontal axis in the longitudinal plane of the Bicycle

new structural design of flexible connections in the drive, where the foot-operated lever connected with one branch of a closed flexible connection to the first freewheel, containing the first circuit Galya and the rope thrown over the envelope of the roller, with the other branch of which is fastened a lever actuator, with the attachment of a flexible connection with the foot levers and manual actuators are connected to the opposite branches of the second flexible connection to the second freewheel through the ropes and the second circuit Galya.

Distinctive features in a variant of the folding bike are: execution frame of two parts, front and rear, while the front part of the frame together 2 front wheel is mounted to rotate around the axis of the lever actuator clockwise from the operating position to lock the front wheel to the shaft with freewheel clutches, and the position on the axis of the roller until it stops at the bottom of the crossbar, thus the free end of the upper crossbar of the front frame provided with a hub bearing on the rear part, for example, in the form of the corresponding projection below the neckline in the back of the frame.

According to the author, the above distinctive features in the criterion level of inventiveness, because despite the generally known lever actuators with a flexible coupling (for example, in the prototype), in known designs of bikes in comparison with the proposed unable to achieve this level of usage of the physical capabilities of a person that has been achieved at the expense of a new execution and layout nodes to implement the motion of the rower, due to the transmission of the movement of the torso and arms through the manual actuator, and movement of the legs through the leg, and through appropriate timing of these movements, performed a new flexible connection.

The designs feature the ability to transfer motion to the wheel and in the reverse, preparatory course manual lever forward, back foot, although this phase of the energy, of course, inferior to the first (the rower second phase is idle), but it is characteristic of the growth efforts of all muscles in the second phase as to operate the food in the convertible version, where the elastic connection brings a new function in addition to the transmission of motion - it is also the element of force holding the front and rear parts of the frame, because the front part in this option, as if supported on the rear when hitting an obstacle or a frontal impact flexible connection works as a shock absorber.

The constructive scheme of the proposed tricycle shown in Fig. 1; Fig. 2 and Fig. 3 shows the sections of the manual drive its placement interaction with shaft drive gear and chain transmission to the fork of the front wheel; Fig. 4 and Fig. 5 the interaction of the hand and foot levers with flexible connections for forward and reverse strokes of the cyclist; Fig. 6 phase the motion of a cyclist.

The bike frame consists of a front 1 and rear 2 parts. The front part includes an upper crossbar 3, which is installed on the axis of the roller 5 mounted on the sleeve 6 on the front forks 7 with the wheel 8.

The lower crossbar 9, on the one hand, connected with the sleeve 6, on the other hand, with the sleeve 10 of the swing lever 11 manual drive.

On the top rail 3 is mounted for oscillation in the longitudinal plane on a horizontal axis 12 of the lever 13 foot-operated the stations in the tubular guide 15, the lower part placed in the sleeve 10 on the horizontal axis 16 perpendicular to the longitudinal plane of the Bicycle.

In the upper part of the lever 11 provided with a handle 17 for the arms of the cyclist, the lower part of the lever 11 through the drive transmission 18 and the chain transfer 19 kinematically connected with the front fork 7 wheels 8.

On the handle 17 mounted levers 17A hand brakes on the front and rear wheels (brakes drum type not shown in the figure).

The rear part of the frame is a U-shaped cross member 20, on the top rail 21 which is placed the saddle 22, the shaft 23 with freewheel clutches 24, 25 and the rear wheels 26 and 27.

The vertical beam of the cross member 20 through a pipe 28 connected to the sleeve 10 manual drive.

The asterisks free-wheel clutches 24, 25 posted by chain Galya 29 and 30, which are connected through cables 31, 32 respectively to the manual levers 11 and 13 foot actuator, and a lever 13 foot-operated, bonded with the upper branch, the Scion of a closed flexible connection on the clutch 24 freewheel containing chain Galya 27 and the cable 31, thrown through the envelope of the roller 5, with the lower branch of which is fastened a lever 11 manual drive, with designated 33, 34 of the flexible mounting is and the second clutch 25 free running through the cable 32 and the second circuit Galya 30.

The operation of the device is as follows.

When riding, the rider sits on the saddle 22, the hand holding arm 17, and setting foot on a support 14 (Fig. 6, POS. 6).

When performing basic power movement the movement of the rower implemented in this design, the cyclist, his feet in the lugs 14 starts to pull the lever 11 manual drive themselves, consistently deflecting back ago, i.e., performs like a "stroke" (Fig. 6 POS. a).

In the result of the efforts of the hands and body of the cyclist, the lever 11 of the manual actuator, rotating on its axis 16 begins to move the lower branch cable flexible connection 31 to the left (Fig. 4).

In the result of the efforts of the foot lever 13 foot drive starts to rotate counterclockwise on its axis 12 and

The resulting displacement of the lever is converted into the movement of the flexible connection flow through the circuit Galya 29 is transmitted to the freewheel 24 and shaft 23, the rotation of which is transmitted to the drive wheels 26, 27.

At the same time move the levers 11 and 13 produce the transfer of motion through the second flexible connection on the freewheel 25, which slips and does not transmit motion to the shaft 23.

During the reverse movement of the arms velo. 5 left).

When this happens the transmission of the labour movement through the second flexible connection 32 on the shaft 23 and wheels 26, 27 through the freewheel 25, while the clutch 24 slips.

Thus, it is alternately transferring motion to the driving wheels in direct and backward movement of the manual levers 11 and 13 foot drives.

For the best transmission of the feet during the reverse movement possible alternative mounting legs and pedal type pedal in drivers-cyclists or using special shoes with a sleeve which when riding a bike clothes on the axis on the lever 14.

To rotate the bike to the right or to the left of the cyclist turns over the control arm 17 of the lever 11, which rotation is through a cardan suspension 18 is transmitted through the chain drive 17 on the front fork 7 with the wheel 8.

Braking when driving through a manual brake, Shoe type, actuators 17A mounted on the front fork 7 with the wheel 8.

For disassembly of the bike during transportation it is necessary to disconnect the locks flexible ties to fasten the flexible connection in the clamps (Fig. 1 locks and clamps not shown), and further, to produce rotation of p is P> Then turn the upper crossbar 3 counterclockwise until it stops at the bottom of the crossbar 9.

The transverse dimensions of the bike can be reduced by performing the lever 11 of the manual actuator and the shaft 23 sliding.

Currently, the author constructed a prototype bike, tested with a positive result, and is working on the commercial development design.
