The invention relates to convertible transporting device, adaptable to various types of terrain and overcome various obstacles.

It is known to be converted transportable device (see U.S. Pat. No. 2215664 (CL B62B 9/02; B62D 55/02, 04, 075) from 22.10.1998 and Engineer, 2008, No. 9, p.15 /containing prohibitative wheel and levers inside the wheel with rollers on the end, drop down into different directions and transformative prohibitative wheel in the caterpillar.

With all the advantages of the device of the prototype payload his limited due to progettisti wheel-tracks.

To eliminate the marked shortage of convertible transporting device containing the wheel and the system of levers with rollers on the end, drop down in different directions, the lever system made according to the type of crank-slider mechanism of breaking the lock, in which the rotary parts of the levers carrying rollers at the end of revolve axis, pivotally connected with the wheel shaft, and the piston rod snap lock has freedom of axial movement on the shaft of the wheel, enabling the position of the rollers in contact with the periphery of the wheel.

The invention is illustrated in Fig., where simplistically depicted convertible transporting device.

Convertible transporting device offers the proposed design, containing from each sides of the wheel 1 and the system of levers with rollers on the end, drop down in different directions, has a system of levers made the type of a crank-slider mechanism of breaking the lock, in which the rotary parts of the levers 2 and 5, the carrying rollers 7 and 8 on the end, revolve around the axes E and D, pivotally connected with the shaft 9 of the wheel, and the piston rod 6 breaking the lock with levers, respectively 3 and 4 has freedom of axial movement on the shaft 9 of the wheel, enabling the position of the rollers 7 and 8 in contact with the periphery of the wheel 1 (see Fig.).

While the links of the crank-slider mechanism satisfy the conditions: BE=CD; AB=AC.

Working position of the rollers 7 and 8 in contact with the periphery of the wheel 1, as in Fig., provided in the conditions of overcoming the transporting device loose terrain or obstacles like stairs for General use. In such conditions pursed to the wheel 1, the rollers 7 and 8 will rotate along with the wheel 1, performing the role of an additional lug without loss of load-carrying capacity of each side of the wheel 1. Thus in Fig. simplistically shown only two rollers of at least six possible in the current design of the device.

Non-operating position of the parts-levers 2 and 5, the supporting rollers 7 and 8, shown as a broken line (the drive mechanism of breaking the lock on the IG. not represented is the author's know-how).

Thus, the proposed technical solution, according to the applicant, is new, involves an inventive step and is industrially applicable.

Convertible transporting device containing the wheel and the system of levers with rollers on the end, drop down in different directions, characterized in that the lever system made according to the type of crank-slider mechanism of breaking the lock, in which the rotary parts of the levers carrying rollers at the end of revolve axis, pivotally connected with the wheel shaft, and the piston rod snap lock has freedom of axial movement on the shaft of the wheel, enabling the position of the rollers in contact with the periphery of the wheel.
