Description

[Detailed description of the invention] The present invention relates to a foldable carrier, in which a plurality of parallel base materials are successively connected by a connecting body crossed in an X shape, and the base materials are expandable and contractible. A board is formed, and a frame is provided around the plywood that expands and contracts together with the plywood, and casters are attached to the four corners of the base, and a handle for pushing by hand is attached to the base material located at one end of the base. By doing so, the purpose is to obtain a carrying tool that can be used for multiple purposes as a handcart, container, etc. when the whole is unfolded, and that can be folded into a small size when not in use.

An embodiment of the present invention will be explained below with reference to the drawings.As shown in Fig. 1, two pipes 1 and 2 with different diameters are fitted together to be expandable and contractible, and the free ends of the pipes 1 and 2 are connected to each other. A base material 5 is formed by bending into bent portions 3 and 4.

A plurality of such base materials 5 are arranged in parallel with the bent portions 3 and 4 facing upward, and the pipes 1 and 2 of adjacent base materials 5 are connected by two connecting bodies 6 that intersect in an X shape. In order to make the connecting part 7 rotatable and to further strengthen and reduce the gap between the base materials 5, a connecting body 8 similar to the above is provided and its X-shaped center part is connected to the pipe 1. A base plate 9 is formed between each base material 5 so that it can be expanded and contracted.

Then, as shown in FIG.
A cylindrical sliding body 10 is fitted into each of the bent portions 3 and 4 so as to be movable up and down, and the adjacent bent portions 3 or 4 and the sliding body 10 are connected by a connecting body 11 that crosses in an X shape. A frame 12 is formed around the base plate 9 to expand and contract together with the base plate 9, and casters 13 are attached to the four corners of the base plate 9. 2 bending part 3,
A U-shaped hand handle 14 is placed between the 4 corners, and in some cases, a foldable horizontal bar 15 is placed between the sliding bodies 10 at the four corners, between the bent portions 3, and between the bent portions 4. You can leave it there.

When this carrying tool is unfolded as shown in Figure 2, it can be used as a handcart for transporting equipment 9, foodstuffs, etc., and when not in use, it can be used as a handcart as shown in Figure 3. It can be folded into a small size.

FIGS. 4 and 5 are views showing other embodiments, in which the frame 12 of the above-mentioned embodiment has been removed.

Even in this manner, it is possible to fully fulfill its function as a handcart.

In addition, as another example, by removing the casters 13 and handles 15 in Figs. 2 and 3 and making it box-shaped, it can also be used as a container for storing various equipment, etc. Furthermore, by placing a plate of the same shape on the base plate 9 or providing a bag-shaped sheet that fits within the frame 12, it is also possible to use it for transporting thin articles.

Furthermore, as another embodiment, as shown in FIG. 6, an annular sliding body 10 is fitted into the bent portions 3 and 4 of the pipes 1 and 2, and the bent portions 3 or 4 and the sliding body 10 are connected in an X-shape. Concatenation body 1 of
1 may be connected to form the frame 12.

As explained above, the present invention involves fitting two pipes with different diameters, arranging a plurality of stretchable base materials formed by bending each pipe upward in parallel, and A plywood board is formed by connecting the substrates with intersecting connectors in a shape that allows expansion and contraction between the base materials, casters are provided at the four corners of the base plate, and a frame that expands and contracts integrally with the plywood is provided around the plywood, Furthermore, since the base material at one end of the plywood is equipped with a handle for pushing by hand, when it is unfolded, it can be used for multiple purposes such as a handcart or container, and when not in use, it can be folded into a small size. Since it can be stored in a bag, it is extremely convenient as a simple transportation device.
