Description

The invention relates to vehicles with a muscular drive and can be used for movement and for training.

A vehicle with a muscular drive is known, comprising a frame, driving rear wheels, a steered front wheel fixed in the bearings of the frame, a rotary guide consisting of two guides with carriages with handles mounted on them, connected with turning the front wheel fork, and two guides for carriages with foot rests, and the movement of the carriages with handles and foot rests is kinematically connected with the rear wheel drive (see copyright certificate SU 1017580. SN Lukyanov 11.01.82.).

However, this vehicle does not allow switching speeds.

A vehicle with a muscular drive with reciprocating pedals is known, comprising two guides with carriages mounted on them with foot rests on which blocks with flexible rods are wound thereon, the axis of the blocks being offset parallel to the axis of the block and placed outside the contour of the block groove . The rods with their other ends are wound on blocks with spiral grooves that are connected to the shafts of the drive wheels through a freewheel.

Speed switching is achieved by winding flexible couplings onto self-braking blocks with displaced axes and switching working sections of flexible couplings to other sections of blocks with spiral grooves. The guide frames and the seat are mounted on the rear drive wheels and front swivel (see copyright certificate SU 1373619. SN Lukyanov 08/19/86.).

This vehicle is the closest to the declared.

However, this gear change is not convenient enough and this vehicle does not allow changing the landing and applying the movement of rowing to the drive.

The aim of the present invention is the ability to change the landing during the movement and automatic speed switching when changing landing.

This goal is achieved by the fact that a bicycle with a linear drive with pedaling and academic rowing movement consists of a frame in the form of two guides, on which carriages with stops for legs, one or two rear drive wheels and a front swivel wheel, the fork of which is fixed in the frame bearings, are installed , the rotation of which is associated with the rotation of the steering wheel and seat with backrest. In this case, the rear wheels are equipped with blocks with spiral grooves for cables connected to the carriages, and the blocks are connected to the drive wheels by freewheels.

What is new is that in order to conveniently automatically change gears when changing the landing, a carriage with a seat is installed on the guide frame, and a back is attached to the seat by a hinge, supported by a roller attached to the frame. At the same time, a number of holes are made on the guide, and a stopper interacting with one of these holes is fixed on the carriage. At the same time, the steering wheel is hinged to the frame under the seat, with the arms covering the sides on the sides and connected with the rotation of the fork by a draft.

The invention is illustrated by drawings.

Figure 4 is a section aa in figure 3.

Figure 5 is a section bB in figure 1, which shows a carriage with emphasis for legs.

A bicycle with a linear drive with pedaling and academic rowing movement includes a frame 1 made in the form of guides 2 and 3 for carriages 4 and 5 with stops for legs 6 and 7. Frame 1 is mounted on one or two drive rear wheels 8 and 9 and a front swivel a wheel 10, the plug of which 11 is fixed in the bearings of the frame 1. The drive wheel 8 has a shaft 12 mounted in the bearings 13 of the frame 1, at the end of which a block 14 with a spiral groove is mounted on the bearing. Block 14 is connected to the shaft 12 by a freewheel 15.

The drive wheel 9 has a shaft 16 mounted in the bearings 17 of the frame 1, at the end of which a block 18 with a spiral groove is mounted on the bearing. Block 18 is connected to the shaft 16 by a freewheel 19. In the case of a version with one rear wheel, blocks 14 and 18 are installed on its sides.

A cable 20 is wound on the block 14, which is connected at the other end to the carriage 4. A cable 21 is wound on the cable 21, which is connected at the other end to the carriage 5. On the guides 2 and 3, the carriage 22 is installed with the seat 23, to which the back is attached by the hinge 24 25, which is supported by a roller 26 attached to the frame 1. The roller 26 is attached to the frame 1 through a pipe 27, clamped by the clamp 28, which makes it possible to install the roller at different heights and adjust the desired inclination of the backrest 25. The carriages 4 and 5 are equipped with axes 28 in in the form of screws and rollers 29.

The carriage 22 is provided with axles 30 in the form of screws and rollers 31.

A stopper 32 is mounted on the carriage, made in the form of a two-shouldered lever 33, mounted on a hinge 34 to the carriage 22. The lever 33 is connected at its other end to a pin 35 installed in the guide sleeve 36 on the carriage 22. The lever 33 is connected to the carriage 22 by a spring 37. The guide 3 is equipped with a series of holes 38, with one of which the pin 35 interacts, thereby fixing the seat 23 on the guides 2 and 3.

A steering wheel 41 with handles 42 and 43 covering the seat 23 laterally is attached to the frame 1 by a hinge with an axis 39 mounted in bearings 40. The steering wheel 41 is connected to the fork 11 by a ball joint 44, a rod 45 and a ball joint 46.

Block 46 is attached to block 14, on which a cable 47 is wound, which is connected to one end of the rubber bundle 48 thrown over block 49 attached to the frame 1.

A block 50 is attached to block 18, on which a cable 51 is wound, which is connected to the other end of the rubber bundle 48. Due to the bundle 48 and winding the cables 47 and 51 onto blocks 46 and 50, the cables 20 and 21 are wound onto blocks 14 and 18 during idle carriages 4 and 5.

The bike works as follows. The driver alternately moves the legs of the carriage 4 and 5, which through cables 20 and 21, blocks 14 and 18, freewheels 15 and 19, shafts 12 and 16 cause the rotation of the drive wheels 8 and 9.

To switch the speed, the driver by the handles 42 and 43 causes the seat to move along the guides 2 and 3, while the cables 20 and 21 go to other sections of the spiral grooves, more remote or closer to the axis of rotation of the blocks 14 and 18. After which he stops the seat 23 stop 32 on rails 2 and 3.

Moreover, with a more horizontal streamlined landing, the gear ratio of the transmission automatically increases. And with a more vertical landing, which is needed when climbing uphill and in difficult road conditions, it decreases. What is needed if the driver wants to use the motion of rowing, he disengages the stop 32 from the guides 2 and 3 and can load the muscles of the arms of the back and abdomen.

The proposed bike allows you to automatically change speeds when changing the landing and allows you to use the pedal as well as the movement of rowing on the drive.

The proposed bike can be used for movement and as a simulator to promote health.
