The invention relates to transport machinery and can be used as individual muscle vehicle.

Known recumbent (Modeler designer, No. 9, 2000, p.2)containing monocoque frame, two front swivel wheels, one rear sprocket with chain drive pedal rigidly mounted seat with back support. The disadvantage of this tricycle is that it no seats not folding and not convenient at transportation in buildings and transport. The distance from the pedals to the seat unregulated and performed under the growth of the owner.

The closest in technical essence adopted for the prototype is foldable recumbent (application No. 2002135878/11(038118)) with a front leading and two rear swivel wheels, containing a foldable frame made of three parts connected by joints, transverse beams connected with the rear part of the frame, and when folded is able to swivel in a horizontal plane relative to the carriage. The drive sprocket is located on the leading front wheel, and the wheel by means of longitudinal tie rod rotates the two rear wheels on the transverse beam.

The disadvantage of this folding design is that there are speakers of the common envelope sharp parts (pedals, horizontal beam steering end of the rack), not fixed swivel wheel in the folded tricycle, making it difficult to move his folded as hand trucks.

The invention solves the problem of compact addition tricycle with rear leading, front swivel wheels and convenience of storage and transportation in the folded position by lock from steering, compact size when folded and the ability to move on its wheels as hand trucks in the longitudinal and transverse directions of rotation around the axis passing through the fulcrum of the drive wheel, the stability of its folded.

To achieve the specified result in folding recumbent containing articulated collapsible frame attached to her seat, one in the rear leading and mounted on the cross beam two front swivel wheels controlled steering wheel through the gear preventing reverse the impact when hitting an obstacle, there is a lever control cables brakes of the front wheels. The frame is made of two articulated folding parts, one of which is telescopic. The sliding of the telescopic frame with holes for locking a spring-loaded clamp with a fixed part of the telescopic frame, the front vertical support attached to the carriage axis leading SV is stocky with rods and pedals with a drive chain drive on the rear wheel. From the top to the body of the carriage axis sprocket attached to the vertical strut in the upper part provided with a sleeve threaded, in which there is a clip with the dog, provide to the addition of hinged backrest to the seat fixing her with a sliding part telescoping frame made through the notch in the upper part of the backrest. In the case of sliding of the telescopic frame has holes for locking its spring-loaded latch in the fixed portion of the telescopic frame. On the body of the carriage axis sprocket fixed bracket attachment chain tensioner, a second bracket mounted on the front of the fixed portion of the telescopic frame that contains: mounting bracket with hole for fixing the folded tricycle spring-loaded clamp with a hole of the fixing bracket mounted on the rear of the frame, brackets, rollers supporting the chain case spring-loaded latch locking the sliding of the telescopic frame with clip telescopic collapsible steering column wheel, gear lever and thrust connected with a rocking chair that has a hole axis of the blocking device from turning the steered wheels in the folded recumbent two hours and a support frame of the seat. On the basis of when Denia attached to the control lever through a system of ropes spring-loaded latch locking the sliding of the telescopic frame. On the rear of the frame attached to the mounting brackets to the axis of the drive wheel, the mounting bracket with a hole and a spring-loaded clamp to secure folded tricycle, two platforms to secure them with clips from "dogs", two stops back seat. One of the clamps lock seat backrest, right in the course of movement, the rod is spring-loaded latch locking the folded hinge frame. Below the fixed portion of the telescopic frame attached to the connecting bracket with hole for fixing the axle and body of a spring-loaded latch locking cross beam from a turn while riding and in the folded recumbent. On the cross beam at the top of the fixed mounting axis, which connects the stationary part of the telescopic frame with cross bar, the ends of which are attached to the vertical carriage brackets swivel axles of the front wheels attached to their brackets, which are attached to the free axis transverse rotary rod connecting between the steered wheels and which are attached to the rocking chair, fixed to a cross beam to which is attached a bracket with a hole for the locking body rocking axis with the dog, which prevents the turning of the steered wheels in the folded recumbent. The rocking chair is now in pomoxis with the dog removed from the pivot point of the tie rod, connected to the rocking chair in the place of its connection with lever gearbox steering column. Cross beam attached to the bracket with the hole by a spring-loaded latch locking cross beam, preventing its spread during the drive. The case of a spring-loaded latch mounted on the connecting bracket. On top of the cross beam made the hole for locking the transverse beams from the reversal in the folded position of the recumbent. Articulated foldable frame is shifted horizontally to the right, while moving from the center of the length of the transverse beams. When folded tricycle drive wheel gets the inclination from the vertical due to the smaller distance from the horizontal axis of the hinge frame to the lower edge of the front wheels in relation to the distance from the horizontal axis of the hinge frame to the lower edge of the drive wheel, providing a reliable resistance recumbent in the folded state, since the center of gravity in the middle of the folded structure, the length of the sliding of the telescopic frame is made equal to 0.86 diameter of the drive wheel, the fixed portion of the telescopic frame - 0.8 diameter of the drive wheel, the rear part of the frame is (0.5+2A) diameter drive wheel, the distance from the hinge to the vertical axis of the drive wheel and from the hinge to the vertical axis mounting axis equal to (0,5+a) diameter of the leading number of the sa, where a is the width of the drive wheel.

The implementation of the cross-beam with wheels length 1.44 diameter of the drive wheel ensures optimal length of the folded tricycle. The location of the mounting axis through the center of the length of the transverse beams and the distance from the axis of the holes for the mounting axis in the connecting bracket attached to the lower part of the stationary telescopic frame to the edge of the open hinge equal to (0,5+a) diameter drive wheel, and the distance from the edge of the open hinge of the rear part of the frame to the axis of the drive wheel is equal to is (0.5+a) diameter of the drive wheel, it finds the drive wheel in the center of the length of the cross beam and does not abut opened the joint in the rotary wheel. Clips from "dogs" on the rear of the frame free lugs backrest and enable when folding recumbent fold hinged backrest and tighten up the clamp with the "dog" on the vertical bar to the sliding of the telescopic frame. The size of the height of the backrest is equal to 1.2 diameter of the drive wheel and prevents the back when folding tricycle to go beyond the dimensions of the folded length of the recumbent. The height of the connection bracket with hole for fixing the axis allows you to install the swivel wheels at the height of providing in the folded recumbent,upright driving wheel located some ground clearance turning wheels when installing folded tricycle three wheel he gets good stability, as the leading wheel gets some incline from the vertical due to the smaller distance from the horizontal axis of the hinge frame to the lower edge of the front wheels in relation to the distance from the horizontal axis of the hinge frame to the lower edge of the drive wheel and the center of gravity in the middle of the folded structure, giving it the most maneuverability when transporting folded velomobile as a handcart. And the distance from the vertical axis of the telescopic frame to the axis of the holes for the mounting axis, the connecting bracket, with the addition of the tricycle, allows you to shift the crossmember from the hinge of the frame, providing for the stability of the folded structure of recumbent length from the vertical axes of the leading and swivel wheels. Center distance vertically open hinge provides the ability to delete from each other and telescopic folding rear frame at a distance, providing not abut the seat in the driver wheel in the folded recumbent. The use of a mounting rack, separate parts of the frames by hinges, spring-loaded clamps, clamps with "dogs" and telescoping frame allows without disassembly recumbent fold.
