Description

[Detailed Description of the Invention] The present invention relates to a case with a reinforcing frame, such as a camera equipment storage case, a travel goods storage case, a cash transportation case, etc.

The applicant of this application has been in the business of manufacturing the case shown in Figure 4 for some time, and this case is
The outer edges of the xy plane wall plate 1, the yz plane wall plate 2, and the zy plane wall plate 3 are orthogonal to each other on the xyz line, and each orthogonal edge portion 4 is provided with L-shaped reinforcing frames 5, 5' made of metal such as aluminum. ，
5'' with their ends gathered at the intersection of the xyz lines, and the corner reinforcing member 7 having the shape of a right triangular pyramid covers the gathering portion 6 of the ends of the reinforcing frames 5, 5', and 5''. The corner reinforcing member 7 and the reinforcing frames 5, 5', 5'' are fixed to the case body using only the rivets 11 that pass through the reinforcing frames 5, 5', 5'' and the corner reinforcing member 7. The head of this rivet 11 is the corner reinforcing member 7.
For example, if the case is thrown onto the floor, etc. when the case is transported as cargo, the head of the rivet 11 will receive a direct impact from the floor, etc., resulting in this. The rivets 11 may be damaged by the impact and the corner reinforcing member 7, the reinforcing frame 7, and the reinforcing frames 5, 5', 5'' may lose their fixing function to the case body, or the rivets 11 may be damaged by the impact.
The tightening of the reinforcing frames 5, 5', 5'' from the outside by the corner reinforcing members 7 becomes loose, and a situation often occurs in which looseness occurs in these parts.

The purpose of the present invention is to eliminate the occurrence of such a situation, and the corner reinforcing frame 5,
The gathering portion 6 at the ends of 5' and 5'' is covered by a corner reinforcing member 7 having a right pyramid shape, and stop pieces 8, 8', and
8" and each stopper 8, 8', 8"
A stepped portion 13 is provided at the base end of the frame, and the stepped portion 13 is engaged with the inner edge of each reinforcing frame 5, 5', 5'', and the stop pieces 8, 8', 8'' are attached to the xy plane wall. Reinforcement frames 5, 5' in plate 1, yz plane wall plate 2 and xy plane wall plate 3,
Rivets 12, 12', 1 on the inside of the intersection of 5"
The rivets 12, 12', which have at least the retaining pieces 8, 8', 8'' secured by securing them with 2''.
This prevents the rivet 11 from being damaged due to direct collision with the floor etc. when the rivet 12'' is thrown out, thereby damaging the corner reinforcing member 7 and the reinforcing frames 5, 5', 5. '' may lose its fixing function to the case body, or the tightening of the rivet 11 may become loose, and the corner reinforcing member 7 that holds both ends of the reinforcing frame 5, 5', 5'' from the outside may become loose, causing play in the same area. This is intended to avoid such a situation and achieve the above-mentioned purpose.

In the illustrated embodiment, the xy-plane wall plate 1, the yz-plane wall plate 2, and the zy-plane wall plate 3 of the aluminum case body is constructed of a wall material in which the outer surface of plywood is covered with an aluminum plate. An aluminum L-shaped reinforcing frame 5 whose edges are orthogonal to each other on the xyz line and which has protrusions 15, 15' on the outer surface of both side edges of each orthogonal ridge 4,
5', 5'' with their ends converging at the intersection of the above xyz lines, and reinforcing frames 5, 5',
A corner reinforcing member 7 having a right triangular pyramid shape is wrapped around the gathering part 6 at the end of the 5", and stop pieces 8, 8',
8" integrally extending, and each stopper 8, 8', 8"
A step 13 is provided at the base end of the yz plane wall plate, and the step 13 is engaged with the inner edge of each reinforcing frame 5, 5', 5'', and the stop pieces 8', 8'' are connected to the yz plane wall plate. The reinforcing frames 5, 5', and 5'' are fixed to the inner side of the intersection of the reinforcing frames 5, 5', and 5'' on the flat wall plates 3 and 2 with rivets 12, 12', and 12''.

As described above, the present invention is such that the outer edges of the xy plane wall plate 1, the yz plane wall plate 2, and the zy plane wall plate 3 are orthogonal to each other on the xyz line, and each orthogonal edge portion 4 is made of metal such as aluminum. The L-shaped reinforcing frame 5, 5', 5'' is
The corner reinforcing member 7 is applied so that the reinforcing frames 5, 5', and 5'' meet at the intersection of the xyz lines, and the corner reinforcing member 7 has a right triangular pyramid shape. At the same time, stop pieces 8, 8', 8'' are integrally extended at three points on the bottom edge of the hem, and a step 13 is provided at the base end of each stop piece 8, 8', 8''. The above-mentioned retaining pieces 8, 8', 8'' are engaged with the inner edges of each reinforcing frame 5, 5', 5'', and the above-mentioned xy plane wall plate 1, yz plane wall plate 2 and zy plane wall plate 3 The reinforcing frame 5, 5', 5'' is fixed to the inner side of the intersection with the rivets 12, 12', 12''. It has excellent effects that can be fully achieved.
