The invention relates to vehicles with a muscular drive, namely, folding bikes to recumbents with landing support on the backrest.

Widely known folding bike, having a hinged connector in the middle of the frame with a vertical axis and the latch that secures the frame in working condition.

(see, for example, the bike Stels Pilot 750 htttp://www.stelsvelo.ru/).

However, this bike has no bearing on the back and inconvenient in the long drive.

Closest to the claimed is a Bicycle that includes a frame with a seat mounted on the rear drive wheel and front swivel wheel the hub of which is provided with a bearing mounted on the axis with a through hole, which is fixed to the swivel fork axle which is fixed in bearings of the frame and provided with a wheel on the end. Thus to the frame in bearings attached to the shaft with cranks and pedals on the ends so that the shaft passes through the hole of the wheel axle. When this shaft is connected with a chain and freewheel with the rotation of the rear wheels.

The plug is provided with two feathers covering the wheel with two sides, one pen which is attached a detachable connection, such as a screw, nut, wound on an axle hole, and the other fork feather attached plug connection, for example by screws, to a lug with a hole, thrown over the axle with the hole at back is receiving and having at one end a flange, when this nut presses the bearing mounted on the axle with a hole for the eyelet and through it to the flange on the end of the axis

(see application No. 2008140541, Lukyanov. S.N.).

However, this bike doesn't work.

The aim of the present invention is to make this bike folding in half.

This goal is achieved by folding the bike recumbent, comprising a frame with a seat mounted on the rear drive wheel and front swivel wheel the hub of which is provided with a bearing mounted on the axis with a through hole, and the axis is fixed to the steering fork of the front wheel with two feathers, the axis of which is fixed in bearings of the frame and provided with a wheel on the end, to the frame in bearings attached to the shaft with cranks and pedals on the ends so that the shaft passes through the hole of the wheel axis, the shaft is connected with a chain and freewheel with the rotation of the rear wheels while one feather plugs attached plug connection, for example a screw, nut, wound on an axle hole, and the other fork feather attached plug connection, for example by screws, to a lug with a hole, thrown over the axle hole, and having at one end a flange, while the frame has two deflecting roller for the two branches of the circuit. What's new is that the frame is provided with a detachable hinge with vertical the y axis and the latch, locking the frame in the working position and the deflecting rollers are located on the same axis, which, with the possibility of longitudinal displacement is installed in the housing, and the housing is mounted to rotate on a horizontal axis, is rigidly attached to the frame, the horizontal axis is equipped with two perpendicular holes, which can include the axis of the rollers by springs connecting the axis of the rollers with the case.

The invention is illustrated by drawings.

Folding bike recumbent includes a frame with a seat 1, mounted on the rear drive wheel 2 and the front swivel wheel 3. The frame consists of frames 4 and 5, connected by a hinge 6 with a horizontal transverse axis. To the frame 4 by a hinge 7 is attached to the absorber 8, which hinge 9 is attached to the frame 5. To the frame 5 in bearings 10 are attached to the axis 11 of the rotary plug 12 and provided with a wheel 13 at the upper end. The plug 12 is equipped with feathers 14 and 15, covering the wheel 3. One feather 14 detachable connection is a group of for example, the screw 16, is attached to the nut 17, wound on the axis 18 with a through hole along it. Another feather 15 plug 12 attached plug connection, for example by screws 19, to the eyelet 20 with a hole, thrown over the axle 18. The axle 18 has at one end a flange 21, which is provided with slots for twisting axis 18 in the nut 17. Between the nut 17 and the ring 18 are clamped two bearings 22, which are mounted in the sleeve 23 of the front wheel 3. To the frame 5 at the sides of the front wheel 3 attached two pipes 24 and 25, in which the ends of the fixed bearings 26 and 27. In bearings mounted shaft of the carriage 28, provided at the ends of the rods 29 and 30 with pedals 31 and 32. Pipes 24 and 25 for rigidity attached to the frame 5 additional spacers 33. The shaft of the carriage 28 is kinematically connected with a chain and freewheel 34 with the rotation of the rear wheels 2. Chain transmission consists of a sprocket 35 and sprocket unit 36 with monetary the shifter 37, on which was drawn the circuit 38. Frame 5 under the seat 1 has a swivel connector 39, which connects it with the second part 40 with a vertical axis, which is provided with a lock 41 in the form of a screw or used in folding bikes eccentric collar. In order not to spoil the foot of the chain 38 to the upper branch of the circuit 38 is thrown over the plastic tube 42, one end of which is attached to the pipe 26. The plug 12 is attached to the stop 43, deflecting both in the Twi chain from the wheel 3 at the turn of the fork 12.

The connecting rods 29 and 30 are mounted on the shaft of the carriage 28 by nuts 44 and 45. Seat 1 is equipped with a guide 46 which is inserted in the clamp 47, attached to the frame 4. The seat is also attached to the clamp 48 mounted on the guide 49, attached to the frame 4. This allows you to move the seat 1 and fix it with clamps 47 and 48 under the length of the legs of the driver.

To part 40 of the frame 5 is rigidly attached to the axle 50 with two perpendicular holes 51 and 52, which can be rotated fixed housing 53. In the housing 53 with the possibility of longitudinal displacement of the installed axle 54 with a handle 55 on the end. On the axis 54 mounted rollers 56 and 57 on the bearings 58 and 59 for the lower and upper branches of the circuit 38. The axis 54 is connected to the housing 53 by a spring 60. The axis 54 can enter the hole 51 in the working position of the bike or in the hole 52 when putting the bike in half. In order for the chain 38 will not slip out of the rollers 57 and 58 above it is limited by the stop 61, attached to the housing 55. When the rotation of the rollers 56 and 57 in the lower position, the chain is twisted by 90 degrees due to backlash in the chain and allows you to fold the bike in half.

Stated the bike has a comfortable fit, provides a comfortable ride on any road and can be folded in half.
