Description

[Detailed description of the invention] (Field of industrial application) This invention is applicable to the transportation, storage, sorting, etc. of industrial parts, processed textile products, rubber, leather raw materials, processed meat products, processed marine products, food products, medicines, etc. This relates to mainly resin container trolleys used for processing purposes, government offices, department stores, supermarkets, markets, distribution centers, etc.

(Prior art) Containers are used in a wide variety of industries as mentioned above, and the sizes of containers vary depending on the industry and are not standardized. A device with dimensions and configuration as shown in Figure 5 was manufactured. The trolley in the figure consists of long L-shaped members 11, 11, short L-shaped members 11',
11' are assembled into a rectangular shape and fixed by welding or tightening with bolts and nuts to form an underframe, and casters 12 are attached to each corner of the underframe to form a dolly,
It came to be used by placing a container on the inside edge of the underframe.

Therefore, it was necessary to manufacture each cart according to the size of the container to be loaded, and the manufacturing cost was high. The truck shown in FIG. 6, which eliminates this drawback, is constructed by inserting four connecting members 14 into four cylindrical corner members 13 to which casters 12 are attached via receiving plates. Connect it to the underframe, tighten it with screws 15, and expand and contract the underframe in the range of 100 mm to 160 mm in the front and back, left and right directions.
Those with adjustable configurations and Utility Models published in 1986-19096
As in the invention of No. 1, the corner member 13 is provided with a through hole, and the connecting member 14 is provided with a pin that is biased outward so as to protrude and hang in the through hole, so that the corner member and the connecting member can be expanded and contracted. Some are connected to form an underframe.

(Problem to be solved by the invention) In the conventional extensible and adjustable trolley mentioned above, the connection between the corner member and the connecting member is fixed by the pressing force of the screws and pins, so the weight of the container constantly placed on it is reduced. If the container is large or used frequently, the screws and pins may come loose or break, resulting in insufficient strength to connect and fix the underframe, which may cause problems such as the risk of the container collapsing or the inability to transport it. It was hot.

The present invention aims to eliminate the above-mentioned drawbacks of the prior art and to provide a container that is robust and has a structure that is easy to assemble, connect, and disassemble at a low cost.

(Means for Solving the Problems) The cart of the present invention includes four corner members constituting an underframe, and a plurality of holes that communicate with a plurality of holes drilled on two orthogonal sides of each corner member. A plurality of connecting members having holes drilled therein, a plurality of fixing frames whose tips are inserted and fixed across each of the corner members and the plurality of holes of the connecting member, and a caster attached to the bottom of the corner member. Consists of.

(Function) The ends of the connecting members are stacked on the two sides of each corner member to form a rectangular underframe, the holes of both members are communicated, and the two sides of each corner of the underframe are Insert the fixing member in an upwardly projecting manner across the plurality of communication holes, attach a nut to the threaded part formed at the protruding end of the fixing frame, and tighten it to fix it to the underframe. At the same time, casters are attached to the bottom of the corner member. Attach it to form a container trolley.

(Example) To explain the example in detail with reference to the drawings, Fig. 1 is a perspective view of a truck, 1 is a corner member, 2 is a connecting member, 3 is a fixed frame, and the corners of each corner member 1 are perpendicular to each other. At the bottom of the two sides, the ends of the connecting members 2, 2 are stacked to form a rectangular underframe, and the fixed frames 3, 3 are opposed to the communicating holes of the two members at each corner. It is attached so that it protrudes upward. The caster 4 is attached to the corner member 1.

In the figure, the corner member 1 has a substantially triangular shape in plan, with concave grooves 1 on two orthogonal sides as shown in FIGS. 2a and 2b.
Two holes 1b and 1b are bored in each of holes 1a and 1a, and a hole 1c for attaching a caster 4 is provided in a triangular receiving plate portion surrounded by the two sides.

As shown in FIGS. 3a and 3b, the connecting member 2 is a bent rod having a substantially concave shape with a cutout in the lower end piece, and has 9 grooves near both ends of the recessed groove portion 2a sandwiched between the receiving plates on both sides of the upper end piece. The holes 2b are formed in close proximity to each other. Note that the number and spacing of the holes 2b can be changed depending on the purpose, and the diameter of the holes is not limited, but the length of the connecting member 2 can be changed to 5 lengths of 260 mm, 360 mm, 460 mm, 560 mm, and 660 mm.
By drilling nine holes 2b at 10 mm intervals on each end of each type, by combining the long and short types and moving the hole of the connecting member forward and backward with respect to the hole of the corner member, The constructed underframe can be adjusted to accommodate almost all commercially available container sizes.

The fixed frame 3 has a gate shape as shown in FIGS.
It forms.

The container is conveyed by being surrounded by fixing frames 3, 3, which protrude upward from each other at each corner of the truck constructed as shown in FIG. 1, and placed on the upper surface of the corner member.

(Effects of the invention) The container truck of the present invention having the above-mentioned configuration and operation has the following features: (1) A plurality of holes are provided corresponding to the corner members and the connecting member, and the holes through which these two members communicate are formed into a portal shape. Unlike fixing with thin screws or pins, by connecting with a bent fixing frame, the underframe can be fixed easily, robustly, and reliably with great strength and no fear of bending or damage. (2) The fixing frame not only connects the corner member and the connecting member, but also protrudes upward from each other at each corner and is securely attached, so each corner is secure when placing a container on it. It is now possible to guide the container and place it on a receiving plate so that it can be firmly held without fear of it shifting or falling during transportation. (3) Furthermore, since the fixed frame is removable, by removing it when not in use, the trolley can be disassembled and stored in a low-volume manner. (4) During transportation, it has become easier to attach ropes or other traction means to the fixed frame.
