Detailed description of preferred embodiments of the invention the First reference will be made to Fig.1, showing the vehicle 100, that is, e is uccio 102, has an arm 103 management, and transporting device 104 corresponding to the variant embodiment of the invention. As will be clear from the following description, the hand truck is just one example of a vehicle that can be fitted with a moving mechanism corresponding to the invention, other examples would be car, truck, wheelchair, motorcycle, trucks, snowmobile vehicle, etc.

Transporting device 104 contains a closed caterpillar 106 supported by supporting rollers 108 and 110, rotatably mounted on opposite ends of the telescopic arm 112, which creates a bias force, pushing rollers from each other. The lever 112 pivotally connected to the shifting mechanism 114, which consists of a shifting lever 116, pivotally connected to the cargo carrier structure 102, and may be selectively rotated by the user around a point 118 of support. Caterpillar 106 flexible, but has a built-in banana device for moving it in a circular configuration, such as a steel strip or wire (not shown), as in conventional tires, embedded in elastic material caterpillars. In addition t is, described below, as well as many others.

In the position of the shifting mechanism shown in Fig.1, the lever 112 is in the upright position, causing the support roller 108 against the caterpillar in its lower part which is in contact with the ground, and the support roller 110 is pressed against the caterpillar in its upper part. In this position, the resistance of the transporting device is minimal, whereby the vehicle gently rolls along the ground surface.

As can be seen in Fig.2, the flexible nature of the tracks 106 allows her to easily overcome obstacles, such as step 120. When approaching the stage of the caterpillar is bent in the shape dictated by the shape of the obstacles. Preferably bias mechanism 114 is actuated, either manually or automatically, or by rotation of the lever 116 around the point 118 of rotation, either by rotation of the lever 112 around a point 115 rotation position 108' and 110', respectively, shown in Fig.2 by broken lines. In this position, the support roller 110 is already on the surface of the stage 120, and the support roller is in position 108', in which it does not interfere to overcome this obstacle.

The specialist will be clear that the bias mechanism may sabathias can be for example, electric, hydraulic or pneumatic and can be associated with known means to actuate and control.

Fig. 3 depicts a vehicle 100 in another position of the transporting device 104. In this position, the lever 116 is rotated 90oaround the point 118 of rotation, whereby the lever 112 is in a horizontal position so that the support rollers 108 and 110 are located in a horizontal plane and each rests on a caterpillar 106 in the two ends of the elongated portion 122, which is in contact with the ground surface. By extension of the piston rod 113 of the lever 112 two support roller 108 and 110 move the caterpillar 106 in the position shown in Fig.4, in which the caterpillar is stretched to its full length. In this position, the contact with the ground surface maximum. While the position shown in Fig.1, suitable for transportation on a firm and level surfaces, the positions shown in Fig. 3 and 4, suitable for transportation on uneven and loose surfaces, and to overcome various obstacles, for example, for ascending and descending the staircase, as will be shown below, etc.

The vehicle 130, which for illustration is presented as a manual phone is the embodiment of the invention, it is shown in Fig.1, but differs from it in that it has a different conveying device 132. In this case, the conveying device 132 includes three bearing rollers 134, 136 and 138. The support roller 134 is located at the end of the first telescopic arm 140, and the support roller 136 is located at the end of the second telescopic arm 142, with two telescopic arm rotatably connected at point 144 with the hinge located on the end 146 of the shifting lever 148 (best seen in Fig.6), similar to the lever 116 variant embodiment of the invention shown in Fig.1, which is hinged at point 150 with the loading structure 102. The support roller 138 can rotate around the axis 152, coaxially with the axis 144.

In the position shown in Fig.5, caterpillar 154, which may be similar to the caterpillar 106 variant embodiment of the invention shown in Fig. 1-4, has a round configuration, and each of the support rollers 134, 136 and 138 against the caterpillar 154 at different points, and the support roller 138 rests on the track at the point of contact caterpillars 154 with the ground. The vehicle 130 has a bias mechanism rotated to retract the levers 140 and 142 from each other in the position shown in Fig.6, where they are, there is she stretched out full length and most of it is in engagement with the ground surface. This provision is applicable when driving on loose ground or for the movement on the stairs, and in this case, the vehicle 130 is optionally contain a mechanism for holding cargo carrier structure 102 is essentially in a horizontal position or at any other angle or to keep the center of gravity is fixed regardless of the angular position of the transporting device. Take into account that the specialist in the art is familiar with such a mechanism, as well as its design and operation.

Fig. 7 depicts a flexible caterpillar 180, corresponding to the variant embodiment of the invention. Caterpillar corresponding to this variant of the invention, made from a variety of links 182 and means of imparting flexibility, and attributed the trend to take a round configuration with connection of the links with each other, which will be described later with reference to Fig.9 and 10. The position of the belt shown in Fig.7 corresponds to the position of the tracks 106, shown in Fig.5, with support rollers 184 support the caterpillar in her round position. However, the support rollers can be moved in the position shown in Fig. 8, which corresponds to the position of the tracks 106, shown in finity 180 refer to Fig.9 and 10, demonstrating part 188 caterpillars in assembled and exploded views, respectively.

The links are arranged in two sets, the first set 190 and the second set of 192. The links of the two sets are identical. Each link has a first surface 194 and a second surface 196, and the first surface of the links of the two sets facing each other. Each link also has a first radial line 198, the second radial face 200, and the first radial face of one of the link facing and adjacent to the second radial faces of the other link and also contains peripheral edge 202 and the inner face 204.

Each link one set of hinge connected to the first angle formed by the faces 198 and 202, with the corresponding angle of the link of the second set by means of hinge pins 210, which are held at the other end washers 212. Each link is also pivotally connected by its second angle formed by the faces 200 and 204, with the corresponding angle of the link in the other set adjacent to the link to which it is pivotally connected to a different angle, and this connection is made by means of pins 214 and washers 216, which may be the same as the pins 210 and washers 212, respectively, or other.

In the first applied coil springs 226 with two terminal branches 228 and 230, and the springs are inserted in the slots 220 and 222 coaxial pins 210 and 214, and their branches 228 and 230 are inserted into the grooves 224 of the two facing each other links. The springs preferably are preloaded so that they create a force tending to bring together the two chains with which they are associated. As a consequence, the caterpillar is spring-loaded so that the links tend to close approach to each other, as can be seen in Fig.9, whereby it takes a round configuration, as shown in Fig.7.

As you can see, each of these angles is smoothed and rounded corner edge, which helps smooth rotary motion.

An alternative embodiment of a caterpillar that is similar to the variant shown in Fig.7-10, it can be seen in Fig.11 and 12. The main difference between these options is that each link 140 has a flat configuration, a L-shaped cross-section, allowing for interaction with a support roller with a groove or two rollers connected to each other, and, in addition, the outer surface 142 can easier be equipped with a rubber cushion to improve the friction force or strip for coupling with the soil.

Another difference from the options shown in figlet in Fig.10, and they are accordingly given the same number as in the original designation. In the coupling mechanism between links of different sets 190' and 192' applied torsion strip 240, which is inserted into the slot 242 and received at each end of the connector 244, firmly planted in the neckline a way as to prevent its rotation. Twisting this band creates a bias force tending to bring together the opposing links. One advantage of this device over the spring device is that the strip may be replaced without requiring disassembly of the caterpillar.

Caterpillar corresponding to another variant of the invention, it is possible to see in Fig. 13-16. Caterpillar 150 corresponding to this variant, has lots of trapezoidal segments 152 are connected to each other by their corners by means of connections 154, each of which forms an elongated hole 156 that receives the pins 158 in opposite corners of the adjacent links. Thus, every two adjacent link can change the distance and angle relative to each other.

Also applied a flexible tie strip 160, which is deducted (and pressed against him), a set of pins 162, located in the inner corners signshow the elasticity of the strip, or is supplied with a tension device, such as a key 166, which turns tightening the wheel 168 on which is wound the end of the tape 160. The other end of the tape 160 is rigidly attached, for example, to one of the pins 162.

As you can see again Fig.13, by loosening the belt tension 160 caterpillar can be translated from its round the positions shown in Fig.13, in its elongated position shown in Fig.14.

Wheelchair 180, provided with a transporting device 182 can be seen in Fig.17. The position shown in Fig.17, like the position of a variant embodiment of the invention shown in Fig.5. As in the case with the embodiment of the invention shown in Fig.5, the transport device can receive an elongated position, which can be seen in Fig. 18, allowing the wheelchair is better to go up and down a flight of stairs 184 and move on various rough terrains.

Two other types of vehicles, motorcycle 190 and off-road vehicle 192, equipped with a transporting device 194 and 196, respectively, according to the invention can be seen in Fig.19-21, each in two different positions: with round position caterpillars (Fig.1E wheelchair 250 in General, consisting of a transporting device 252 and the loading structure 254, which in this version of application is the landing element of the wheelchair. Transporting device 252 includes a closed caterpillar 256 supported by supporting rollers 258, 260 and 262, which are installed on the bias mechanism 264.

Bias mechanism 264 includes a frame element 265 in General, having the form of a sector of a circle, and formed on its periphery element 266 part 268 in the form of a curved rail. The roller 258 rotatably mounted on the end of the peripheral element 266, and the roller 260 rotatably mounted atop the frame 265 in the form of a sector. Item 270 in the form of arcuate slats mounted coaxially with part 268 in the form of a rail and sliding into it, and the roller 262 rotatably mounted on its free end. Boarding element 254 with the possibility of displacement of the supported element 266 in the form of a segment, as will be made clear hereinafter.

In position, which can be seen in Fig.23, item 270 in the form of arcuate slats entirely included in part 268 in the form of a rail, whereby the caterpillar 256 takes her round configuration, as described in the previous variadic contact with the ground.

In the position shown in Fig. 24, the element 270 in the form of arcuate slats retracted from part 268 in the form of a curved rail with simultaneous displacement of the frame element 265 clockwise around the axis of the roller 260, whereby the rollers 258 and 262 are aligned with roller 260, shifting the caterpillar so that it is drawn at full length, and in this position she is in maximum contact with the ground surface and is suitable for transporting a wheelchair on uneven terrain and obstacles, as a rule, to climb or descend several flights of stairs.

As can be further noted that the frame element 265 is equipped at its rear end free wheel 272, which in the position shown in Fig. 23, is in contact with the ground, whereas in the position shown in Fig. 24, it is raised from the ground. Also it will be clear that the mutual offset curved rail 270 relative to the arcuate portion 268 is facilitated by the electric motor, which is in itself known. A typical wheelchair, corresponding to a variant of implementation of the present invention, will be equipped with a mechanism for retaining the essentially horizontal position or to maintain a stable CEM to a person skilled in the art.

Difference in speeds of faster-moving and slower-moving tracks depends on position of control common for wheels and tracks. Current values of movement of steering gear elements are recorded in matching device. Said matching device, with due account of speed of movement of vehicle center of masses, forms control action onto unit which controls stepless steering mechanism. Said control unit provides values of speeds of faster-moving and slower moving tracks required for coincidence of centers of turning of wheel and track drives.

EFFECT: improved steerability of wheel-and-track vehicle and accuracy of cornering.
