 An embodiment of the present invention will be described below with reference to the drawings.

The assembly-type transport vehicle shown in FIGS. 1 to 3 includes a dolly (1), four shelf members (5), and four columns (9).

The dolly (1) is composed of a base (2) having casters (3) mounted near the four corners thereof, and a pillar insertion square pipe (4) fixed to the four corners of the base (2).

The shelf member (5) is composed of a rectangular shelf board (6) and shelf frames (7) arranged on both sides of the shelf board (6). At both ends of the shelf frame (7), hook portions (8) projecting in the longitudinal direction are provided. The length of the shelf plate (5) is slightly smaller than the interval between the rectangular pipes (4) in the longitudinal direction.

Each of the columns (9) is a rectangular tube having an outer surface shape that matches the inner surface shape of the square pipe (4) and is detachably inserted into each square pipe (4). Each square pipe (4) is provided with a pin insertion hole at the lower end of the opposing side wall, and the pin (1 2) is inserted into this pin insertion hole. A semi-circular cutout (13) is provided at the lower end of each side wall of each strut (9) .By engaging the notch (13) with the pin (12), the strut (9) Is fixed to the square pipe (4).

A large number of hook insertion holes (10) are provided at predetermined intervals on any one of the side walls of each square pipe (4), and another one is provided at predetermined intervals. Three hook insertion holes (11) are provided. If each pillar (9) is fitted into each square pipe (4) so that a large number of hook insertion holes (10) face each other, one of these hook insertion holes (10) with a predetermined height is By selecting, the shelf member (5) can be mounted at any height. Also, by fitting the columns (9) into the square pipes (4) so that the three hook insertion holes (11) face each other, the work of attaching the shelf member (5) becomes easy, and the same item is always placed. It is convenient in such cases.

A reinforcing frame (14) is welded to the upper end of each square pipe (4). The lower end of each square pipe (4) is projected downward from the base (2), and at the lower end of the square pipe is a bottomed rectangular tube with an inner surface shape that matches the outer surface shape of the reinforcing frame (14). The fitting part (15) of is welded. The fitting portion (15) is fitted over the reinforcing frame (14) of the square pipe (4) when the trucks (1) are stacked to prevent the truck (1) from collapsing.

When assembling the above-mentioned truck, after inserting the support columns (9) into the square pipes (4) respectively, insert them into the hook insertion holes (10) (11) at a predetermined height of the support columns (9). Insert the hook part (8) of the shelf member (5) and attach the shelf member (5) to the column (9).

When storing the transport vehicle or moving only the transport vehicle, the transport vehicles are disassembled, and when there are a plurality of transport vehicles, they are stacked as shown in FIG. That is, after removing the column (9) and the shelf member (5) from the carriage (1), the shelf member (5) is slightly displaced so that its hook part (8) does not interfere with the square pipe (4). Stacked on the dolly (1), the columns (9) are stacked side by side on the top shelf (5). When there are multiple vehicles, the carts (1) on which the shelf members (5) and columns (9) are stacked are stacked, but at this time, the square pipes (1) of the carts (1) to be placed on top are stacked. Fit the fitting part (15) provided at the lower end of 4) to the reinforcing frame (14) provided at the upper end of the square pipe (4) of the truck (1) below (see Fig. 5). ). A space equal to the height of the square pipe (4) is secured between the upper trolley (1) and the lower trolley (1), and the shelves (5) and columns (9) are provided in this space. 3) It can be stored without interfering with other things. This prevents the carts (1) from collapsing and allows the carts (1) to be stacked in a stable state.

In the above embodiment, the structure of the shelf member (5) can be variously changed. For example, the length of the shelves can be increased so that the four corners of the shelves are cut out so that they do not get in the way when stacking on the truck (1). In this way, a shelf board with a large mounting space can be obtained. The hook portion of the shelf member may be a member different from the shelf frame. Further, the plurality of insertion holes provided in the support column (9) may have different shapes, for example, every other one. In this way, the work of horizontally attaching the shelf member (5) to the column (9) is facilitated. The fitting part (15) may be provided on the upper end of the square pipe (4).

[Effect of device]

 According to the assembling truck of this invention, when assembling this, after inserting the columns into the pipes respectively, the hooks of the shelf members are inserted into the hook insertion holes at a predetermined height of the columns. Since the shelf members may be attached to the columns, the assembly is easy.

When the carrier is not used or when only the carrier is moved, after removing the columns and the shelf member from the carriage, the shelf member is slightly displaced so that its hook portion does not interfere with the pipe. The storage space is small because the columns can be stacked on top of each other and the columns can be stacked on the shelf members.

Further, when there are a plurality of vehicles, the lower ends of the pipes of the trucks to be placed on the lower trucks are fitted to the upper ends of the pipes of the lower trucks, whereby the trucks can be stacked in a stable state, and Since the rack members and columns are housed between the upper and lower trolleys without interfering with other members, it is possible to reduce the floor area required to store a plurality of transport vehicles.
