Description

[Detailed description of the invention] Industrial application field This invention is designed to store and store a large number of items that are often handled mainly in stores, etc.
This relates to an article transport device used for loading and transporting articles on a truck or the like.

BACKGROUND ART Conventionally, as this type of article conveyance device, a structure disclosed in, for example, Japanese Utility Model Application Publication No. 56-63665 has been provided. In other words, the article carrier has a rear frame (rear frame body) and two side frames (side frame bodies) facing each other at the front on both left and right sides of the rear frame in a gate shape in plan view. Wheels for movement are provided at the bottom of each horizontal frame member that connects the lower end sides of both side frames, and a bottom frame for carrying goods (bottom frame body) located horizontally or almost horizontally is arranged between both horizontal members. It is set up. The rear frame and side frame are made of an external member formed by bending a pipe material into a gate shape, a plurality of vertical wire members arranged between the top of this external member and a horizontal member, and a plate-shaped member. It is formed from multiple horizontal members. One side frame and the rear frame are connected to each other by a short connecting member so as to be relatively swingable, and the other side frame and the rear frame are connected to each other by a long connecting member so as to be relatively swingable. It is connected. The bottom frame for carrying items is made of a rectangular outer member and a wire rod fixed between a pair of opposing sides of this outer member, and can be placed between horizontal members or placed on the rear frame. It is mounted so that it can swing freely.

In addition to such a trolley-type article conveyance device, for example, as seen in Japanese Utility Model Publication No. 55-37474,
A box pallet type with support legs at the bottom and no wheels is also available. In this case, the four sides are side frames, and each side frame has a mesh shape in which a plurality of vertical wire rods and a plurality of horizontal wire rods are disposed orthogonally.

Problems to be solved by the invention According to the conventional structure of the former mentioned above (Japanese Utility Model Application Publication No. 56-63665), sufficient strength can be expected because the external material is a pipe material, but it is expensive.
Furthermore, since multiple types of parts such as pipe materials, wire rods, and plate-shaped materials must be prepared, processing operations to obtain each part are troublesome, and processing equipment for each is required. Since the free ends of the vertical wires and horizontal members are fixed to the portal-shaped inner surface of the external material by welding, they are vulnerable to internal pressure from stored items and external pressure from collisions with other objects. Sometimes it comes off easily.

Furthermore, the conventional structure of the latter (Japanese Utility Model Publication No. 55-37474) is similarly weak against pressure, and the portion corresponding to the external material is also a welded combination of vertical wire rods and horizontal wire rods. Therefore, the overall strength becomes weak.

The purpose of the present invention is to provide an article carrier whose side frame body can be formed without using pipe materials or plate-like plates, and which can be expected to have sufficient strength against pressure, etc. .

Means for Solving the Problems In order to achieve the above object, the article carrier of the present invention has a plurality of side frames and a bottom frame, in which the side frames are made of rod material in the form of a gate. a pair of external members on the inside and outside that are integrally formed; a horizontal wire member disposed between a pair of opposing vertical sides of the external member, and whose both ends are fixed between the pair of external members on the inside and outside;
It is constituted by a vertical wire rod which is disposed to intersect with this horizontal wire rod and whose upper ends are fixed between a pair of outer members on the inside and outside.

Effects According to the configuration of the present invention, since the side frame body is formed of the rod material and the wire material, pipe materials and plate-like materials can be made unnecessary, and the processing equipment for these materials can also be made unnecessary. The side frame body has a gate shape and is integrally formed with a pair of external members on the inside and outside to obtain the overall strength, and furthermore, the mesh portion consisting of the horizontal wire material and the vertical wire material has both ends of the horizontal wire material and the vertical wire material.
