The technical field to which the invention relates.

The invention relates to velotron, namely to design the side of the trailer connected to the bike, which is foldable and which is used to transport people and cargo.

The level of technology

Known foldable stroller-trailer for a Bicycle having a chassis comprising an outer rectangular frame and two internal frames that are attached to the outer frame in the plane of the chassis parallel to the sides of the stroller. On the sides of the chassis are mounted supports for fastening axes of the two wheels, and the plane of rotation of each wheel is located between the outer and inner frames. Chassis hinged two U-shaped beams, which can be rotated from a folded position parallel to the chassis in extended position perpendicular to the chassis. Beams fastened with loops, each of which has a base connected to the chassis between the outer and inner frames, and the axis on which it rotates the butt of the beam. The base of the loops have a cylindrical protrusion, which is included in the end face of the inner frame; a hole aligned with the hole in the outer frame, and a screw, which passes through the hole of the outer frame and the hole in the base. Screw screwing in the connector of the inner frame, securing the base of the loop on the outside of the frame, while cylindrical in the stupas provides the installation of the inner frame. A hinged vertical stops that limit the rotation to a vertical position. The stroller also has a mechanism for holding the side rails in the extended position, the bracket connected to the Bicycle, and a host of hinge fastening bracket on the chassis can be rotated from a folded position parallel to the chassis in extended position on the front side of the chassis (see U.S. patent No. 5020814, CL VC 27/02, 1993).

The disadvantage of this folding stroller-trailer for a Bicycle are the design complexity, the limited functionality.

Known volokolamka containing a Bicycle frame for shipping, wheel, mounted on the side of the frame on an axis, and fastening elements, and the frame is made in the form of a tubular frame, U-shaped, smoothly curved upward from the middle and constitutes the basis of a stroller, comprising three transverse tube, with the latter two pipes are located on the gently curved upward tubular frame and have the seat Adjuster and shock-absorbing springs can be moved along the tubular frame, a curved outer side pipe for mounting the wheel, the curved pipe for mounting wing reflector, curved at an angle of 90°front and rear tubes and front and rear connecting rods for fastening the number of the ski to the bike, the curved angle of 90° front and rear tubes of the upper part are attached by means of fixing elements made in the form of castles, to the pipe steering steering column and seat tube, and the lower part is fixed to the tubular frame, the front link rod to its upper part is attached to the steering column of the Bicycle, and the lower part to the base curved at an angle of 90° front tube of the stroller, the rear connecting rod one end of which is attached to the lower bridge to the Bicycle frame and at the other end to the tubular frame at the base of the curved at an angle of 90° rear tubes of the stroller, while the front part of the tubular frame connected with the first cross pipe by means of a vertical pipe that carries the carriage, and the third pipe is made as of the beginning of the trunk for cargo, while the carriage is further provided with a pedal-operated, consisting of pedals with rods, mounted coaxially on the carriage, the two leading domestic and foreign stars and two slaves inner and outer sprocket installed on the brake hub wheel, and the driving and the driven sprocket coupled between a chain transmission, which is equipped with shields, and stretch the chain gear set with wheels and roller, the leading internal asterisk installed on the axis of the cradle and leading external is Yaya star and led internal installed on the shaft, the latter is mounted on two bearings (see U.S. Pat. Of the Russian Federation No. 2161577, CL VC 27/00, UK 7/00, publ. 10.01.2001,).

The disadvantage of this Volokolamsky are high energy costs while pedaling and load distribution.

The closest in technical essence and the achieved positive effect and adopted by the authors for the prototype is the side of the trailer to the bike, containing the skeleton, forming the cargo capacity, wheel, mounted on the side of the frame on an axis, and fastening elements made in the form of a rigid plate with holes for the axle of the rear wheel of the Bicycle and two clamps for connection of a trailer in accordance with the receiver chain of the fork and the top element of the frame of the bike, with the fastening elements mounted on one side of the frame, the bottom of which is mounted a rigid plate on which is fixed a clamp for connecting the trailer with a tube chain fork and yoke for connection with the upper part of the frame of the Bicycle is mounted on the upper edge of the side frame, and in the lower part of the opposite side of the last fixed additional hard plate under the axle of the wheels of the trailer (see A.S. USSR №1206166, CL WK 27/12, 7/04).

The disadvantage of this side of trailer single-track vehicles are limited functionality, as well as nevoso the ability to use muscle power of another person, involved when riding together.
