Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a hand truck that moves while pushing a track.

[0002]

[Prior art]

 As shown in FIG. 4, the conventional hand truck is composed of a hinge a, which is foldably connected, and an L-shaped metal fitting provided on the lower surface of the cart to form a carriage d. Further, generally, wheels e and f traveling on tracks are provided at the ends of the frames b and c on shafts g and h, respectively, and are attached to the frames b and c by bearings.

[0003]

[Problems to be solved by the device]

 In the conventional trolley, in order to transport the dolly, the above-mentioned metal fittings of the frame are released, then the frame is folded around the hinges and piled up and then moved by two people, but only folding is required. Therefore, it is heavy and difficult to convey. In particular, it is not possible to carry it into a narrow space (subway, etc.), and it has to be disassembled into individual parts. However, once disassembled, there is the inconvenience that it takes time to assemble, etc., and disassembly is easy and further assembly is possible. There was a demand for a convenient dolly.

[0004]

[Means for Solving the Problems]

 In view of such circumstances, the present invention disassembles the frame body into two in order to deal with the above-mentioned problem, and fits two guide shafts provided with wheels to the guide supports provided in the two frame bodies. (EN) Provided is a trolley having a structure in which the respective members can be easily assembled or disassembled so that they can be inserted and removed from the mating groove and the guide portion.

[0005]

[Action]

 In order to assemble the bogie 1, the present invention includes wheels 2 and 2 mounted on a rail R in a fitting groove 6a of a guide support 6 attached to the front and rear lower surfaces of one of the two divided frames 1a and 1b. And the rectangular bearing bodies 7 arranged on the respective axles 4 and 5 of 3 and 3 are fitted, and the groove 7a provided in the bearing body 7 is fitted so as to be guided by the guide portion 6b of the guide support body 6, and the frame body 1a is fitted. Support.

The guide support 6 provided in front of and behind the other frame 1b has the rectangular bearings 7 and the grooves 7a arranged on the axles 4 and 5 in the same manner as described above, and the guide groove 6a and the guide support 6 are guided. The bogie 1 is assembled by being fitted so as to be guided by the portion 6b and supporting the frame 1b. Further, if necessary, the trolley 1 can be further strengthened and assembled by using the tightening mechanism 12 arranged before and after the frame bodies 1a and 1b, but the tightening mechanism 12 is not always necessary. Further, when disassembling, by reversing the assembling work, the two axles 4 and 5 and the two frame bodies 1a and 1b can be easily disassembled to facilitate carrying.

[0007]

【Example】

 1 to 3 show an embodiment of a hand truck according to the present invention, which will be described in detail with reference to the drawings.

1 is a dolly, and the dolly 1 is composed of two frame bodies 1a and 1b on which floor materials are laid and two axles 4 and 5 with wheels 2, 2 and 3, 3 arranged on the left and right sides. To be done. A guide support 6 is attached to each of the frame bodies 1a and 1b on the front and rear lower surfaces on the left and right end sides, and on the front and rear lower surfaces on the other end side of one frame body 1, respectively. The guide support 6 is provided on each of the left and right sides and the center of the axles 4 and 5, and a fitting groove 6a for guiding and fitting a rectangular bearing body 7 which bears the axles respectively, and a groove provided on the bearing body 7. A guide portion 6b for fitting and guiding 7a is provided, and a bearing body 7 is fitted to this guide support body 6 to support the frame bodies 1a and 1b.

Further, the front and rear joints of the frame bodies 1a and 1b are joined to each other on one frame body 1b side by an annular metal fitting 9 for hooking a hook 8a, and on the other frame body 1a side, an annular metal fitting. Corresponding to No. 9, a pull rod 8 provided with the hook 8a at the tip, a handle 10 in which the base end of the pull rod 8 is pivotally supported in the center through a pin, and a frame body in which the tip of the handle 10 is pivotally supported A tightening mechanism 12 including a metal fitting 11 attached to the No. 1 is provided. In this case, when the tightening mechanism 12 is tightened, the line connecting the hook and the pin at the proximal end of the pulling rod is located inside the dead end of the tip shaft support of the handle 10, and when tightening and releasing the shaft. After passing through the dead point of the branch, it becomes an external position, and the tightening is easily released by operating the handle 10.

Reference numeral 13 denotes a handle portion provided on the side of the frame bodies 1a and 1b, which serves as a handle when disassembled and carried, and a pawl engaging member when inserting a pawl when the carriage 1 is stopped and braking. It is also designed to function as a stop ring.

[0011]

[Effect of device]

 As described above, the present invention has two divided frame bodies and two axles arranged on the front and rear wheels that move on the rails. The axles are supported on the left and right sides and in the center, respectively. A bearing body having a groove to be formed, and further, on the lower front and rear surfaces of the frame body, a guide support piece for fitting and guiding the groove of the bearing body with a fitting groove interposed is attached to the bearing body. The trolley is configured so that it can be fitted and supported.By dividing it into small parts, it is convenient to carry it especially in a narrow space, and the trolley can be used at night and from the last train. Since it is used within a limited time of 2 to 3 hours, it is necessary to be able to easily assemble and disassemble. Therefore, the present invention has an effect that it can be assembled and disassembled easily and it does not take time because the assembly is supported only by fitting without using screws or the like.
