Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a transportation box such as a van truck, a ban trailer, and a container, and more particularly to a structure of left and right side walls and a mounting structure thereof.

[0002]

2. Description of the Related Art Conventionally, the structure of a carrying box having a roof portion, left and right side walls, and a front wall has a structure in which the upper and front ends of an outer plate are fixed to the upper and lower end frames of the left and right side walls with rivets. However, since the head of the rivet protrudes to the outside, the rivet has a bad appearance, and the fixing part of the rivet becomes loose during long-term use, causing problems such as intrusion of rainwater.

[0003]

In order to solve this problem, as shown in Japanese Utility Model Publication No. 6-20716, the head of the rivet was covered with a cover member. As a result, the outer wall of the side wall and the cover were covered. A step was formed between the member and the side wall on which advertising letters and pictures were drawn, and the man-hours required for manufacturing were increased.

Further, instead of fixing with a rivet, an adhesive or an adhesive tape has been used for adhesion. However, as an inevitable problem in this case, it is easy to peel off from the end of the adhesive portion.
There was an inherent problem such as a noticeable dimensional error at the end.

The object of the present invention is to improve the appearance by increasing the difference between the outer plate surface of the left and right side wall portions and the mounting portions of the roof portion and the front wall portion as much as possible in order to improve the appearance. The purpose of the present invention is to provide a structure for a transportation box that requires less man-hours.

[0006]

In order to achieve the above object, there is provided a carrying box body comprising a roof portion, left and right side wall portions, and a front wall portion, and upper ends of the side wall portion and the front wall portion extend upward. It is composed of a frame member composed of an aluminum shape member provided with a protruding piece, and an inner upper edge or a front edge of a side wall outer plate is adhered to the protruding piece with an adhesive or an adhesive tape, and the upper end and the adhesive of the protruding piece are adhered. An inner upper edge or a front edge of the side wall outer plate is inserted into one edge, and the other edge is provided with a mounting portion fixed to the roof or the edge of the front wall. Provided is a structure of a carrying box body, characterized in that an end portion of the roof portion or the front wall portion and left and right side wall portions are joined by a cover member made of an aluminum profile having a relatively large radius of curvature. .
