[Effect]

When using the tire transport trolley of this invention, it is first necessary to assemble it. However, at this time, the side frames are assembled to the back frame, and then the back frame and side frames are supported. Attach it to the stand. At this time, open the mating holes in the back frame one by one from the long mating pins. The short mating pins must be mated one after another, so if multiple locations are mated at the same time, This makes the work easier and improves work efficiency compared to the case where the Then assemble like this After stacking multiple tires horizontally one after another on a cart, the side frame is closed and the The side frames are connected to each other or the side frames and the back frame by a connecting tool to prevent the side frames from being opened. In this state, it is loaded onto the bed of a truck, and the tires and trolley are transported. And the truck When the truck arrives at its destination, the tires and truck are lowered, and then the tires are removed from the truck. vinegar. After that, the cart is stored or returned, but at this time, the cart is Since it is broken down into small parts and side frames, the bulk becomes smaller and easier to handle. , the occupied space can also be reduced.

[0007] Further, if configured as described in claim 2, the fitting length between the fitting pin and the back frame is long. Therefore, even if the diameter of the mating hole is slightly larger than that of the mating pin to facilitate the mating process, the back The frame does not wobble at all. Furthermore, if the diameter of the wheels is increased as claimed in claim 3, there will be a concave surface on the transfer path. Even if there is a bump, it can be easily overcome and the transfer becomes smooth.

It has a large diameter of over 100mm. In addition, the base 1 has upper and lower The lower ends of two or more fitting pins 6, here two fitting pins 6, extending in the direction are fixed, and these The fitting pins 6 are arranged at the tips of the base 1, respectively. The length of these mating pins 6 are quite long, more than 150 mm, and have different lengths (here, the mating pin pin 6a is longer than mating pin 6b). 11 is a back frame extending in the vertical direction; The back frame 11 extends vertically and has two vertical frames separated by the same distance as the distance between the fitting pins 6. 12, and a support plate 8 that connects the upper ends and center parts of these vertical frames 12. It is composed of two horizontal frame bodies 13 that curve along the outer edge. These vertical frame bodies 12 The vertical frame body 12 and the horizontal frame body 13 are each composed of a hollow pipe, and thereby the vertical frame body 12 is It will have a fitting hole 14 at the end. This back frame 11 is located at the lower end of each vertical frame body 12. That is, by fitting the fitting hole 14 into the fitting pin 6, it is removably attached to the support base 3. I'm being kicked. 18 and 19 are side frames formed by bending hollow pipes. The side frames 18 and 19 each have a vertical frame body 20 extending vertically, and a vertical frame body 20 extending from the top and bottom ends of the vertical frame body 20. It is composed of horizontal frame bodies 21 and 22 that extend horizontally, and has a U-shape as a whole. . Ring-shaped bosses 24 and 25 are attached to the base ends of the side frames 18 (inside ends of the horizontal frames 21 and 22). The base end of the side frame 19 (the inner end of the horizontal frame bodies 21 and 22) has a ring-shaped bolt. 26 and 27 are fixed respectively. The side frame 18 has bosses 24 and 25 as a back frame. The back frame 11 is fitted to the upper and lower ends of the vertical frame 12 that constitutes one side end of the back frame 11. The side frame 19 is detachably and rotatably attached to the back frame 11, while the bosses 26 and 27 are attached to the back frame 11. By fitting into the upper and lower ends of the vertical frame body 12 constituting the other end, the back frame 11 They are detachably and rotatably connected. Above the free end of each side frame 18, 19 (vertical frame body 20) Hooks 30 and 31 are fixed to the lower central part, respectively, and the hook 31 has a connecting tool and a One end of the chain 32 is connected. And this chain 32 is the side frame 18, 19 is closed as shown by the imaginary line in FIG. 2, the other end is pulled to the hook 30 of the side frame 18. By being hung, the free ends (vertical frame bodies 20) of the side frames 18 and 19 are connected to each other, and the side frames 18 and 19 Prevents rotation in the opening direction. The support stand 3, back frame 11, and side frames 18 and 19 mentioned above are the entire The tire transport trolley 34 is configured as follows.

[0009] Next, the operation of one embodiment of this invention will be explained. When using the tire transport trolley 34 as described above, first Needs to be assembled. At this time, attach bosses 24, 25, 26, and 27 of side frames 18 and 19 to the back frame. The side frames 18 and 19 are connected to the back frame 11 by fitting the upper and lower ends of the vertical frame 12 of 11, respectively. Next, fit the lower end of the back frame 11 (fitting hole 14) into the fitting pin 6, and Attach frames 18 and 19 to support stand 3. At this time, open the fitting holes 14 of the back frame 11 one by one In order to fit sequentially from the longer fitting pin 6a to the shorter fitting pin 6b, connect multiple locations at the same time. Compared to the case where they fit together at the same time, the work becomes easier and work efficiency improves. Also, this When , the length of both mating pins 6 is 150 mm or more, so mating pin 6 and back frame 11 As a result, the mating hole 14 has a slightly larger diameter than the mating pin 6. Even if the fitting operation is facilitated, the back frame 11 will hardly wobble.

0010 Next, after rotating the side frames 18 and 19 in the opening direction to the position shown by the solid line in Figure 2, the tie While pressing the roller T against the two vertical frames 12 of the back frame 11, place it on the support plate 8 as shown in Figures 4 and 5. Lay them horizontally and stack them one after another. Then, a predetermined number of tires T are placed on support stand 3. When the tires T are stacked up, the side frames 18 and 19 are closed until the vertical frame body 20 comes into contact with the outer circumference of the tire T. direction. As a result, the tire T is moved outward by the back frame 11 and side frames 18 and 19. It is supported at 3 points or more, here at 4 points. Then the chain 32 Hang the other end on the hook 30 to connect the free ends of these side frames 18 and 19, and Prevents frames 18 and 19 from rotating in the opening direction. Next, move the truck 34 along with the tires T. However, since the cart 34 has large-diameter wheels 7, the transportation process is slow. Even if there are bumps in the road, it can be easily overcome, making transportation smoother. . Next, after loading this truck 34 along with the tires T onto the truck bed, The truck 34 and the tires T are transported by the truck. Then, when the truck reaches its destination , lower the truck 34 and the tire T, and then remove the chain 32 from the hook 30. At the same time, the side frames 18 and 19 are rotated in the opening direction. Next, place the tire T on support stand 3. Take out one by one. After all the tires T have been taken out, the trolley 34 is stored. Otherwise, it is returned, but at this time, the cart 34 is moved to the support base by the reverse operation of the above-mentioned assembly. 3. It can be broken down into the back frame 11 and side frames 18 and 19, making it smaller and easier to handle. At the same time, the space occupied can also be reduced.

[0011] In the above embodiment, the side frames 18 and 19 are connected to both ends of the back frame 11. However, in this invention, the side frame is connected to either side end of the back frame 11. You may also do so. In this case, the free end of the side frame and the side frame may be connected by a coupling device. This will connect the other side end of the back frame that has not been connected. Also, this idea In this case, tires T with different outer diameters are loaded on the same tire transport trolley 34. You may.
