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 5 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, and The structure was such that a caster 22 was fixed directly to the inner side of the intersection of the reinforcing frames 5 and 5' on the xy plane wall plate 1.

In the conventional case described above, the head of the rivet 11 is located on the outer surface of the corner reinforcing member 7 in a state that protrudes from the same surface, and for example, when the case is transported as cargo, if the case is thrown onto the floor etc. As a result, the head of the rivet 11 receives a direct impact from the floor, etc., and the rivet 11 is damaged by this impact, causing the corner reinforcing member 7 and reinforcing frames 5, 5',
5'' to the case body, or the tightening of the rivet 11 becomes loose, and the corner reinforcing member 7 that holds both ends of the reinforcing frame 5, 5', 5'' from the outside loosens, causing looseness in the same part. In addition, the mounting portion of the castor 22 was not sufficiently strong.

The object of the present invention is to eliminate the above-mentioned defects and to provide a case with a new reinforcing frame in which the mounting portion of the castor 22 is reinforced.

In order to achieve the above object, the present invention covers the gathering portions 6 at the ends of the reinforcing frames 5, 5', 5'' with a corner reinforcing member 7 having a right pyramid shape, and the hem edge of this corner reinforcing member 7. At the three-point location, there is a stopper 8,
8', 8'' are integrally extended, and each stopper piece 8, 8',
A stepped portion 13 is provided at the base end of each reinforcing frame 5, 5', and 5'', and the stepped portion 13 is engaged with the inner edge of each reinforcing frame 5, 5', and 5''. Reinforcement frame 5 in xy plane wall plate 1, yz plane wall plate 2 and xy plane wall plate 3,
Rivets 12 and 1 on the inside of the intersection of 5' and 5''
2 and 24, and a metal backing plate 16 is brought into contact with the inner side of the intersection of the reinforcing frames 5 and 5' on the xy plane wall board 1, and a gutter-shaped groove is formed on the two edges of this backing plate 16. The bent edges 19, 19' are provided to form the gutter-like bent edges 19,
19' is the protrusion 15, 1 provided on the reinforcing frame 5, 5'.
5', the corners of this plate 16 are fixed with rivets 20, and a caster 22 is arranged on the outside of the plate 16, and the caster 22 is attached to the plate 16.
It is fixed by rivets 23 and rivets 24 at the reinforced points and the fixing points of the stopper piece 8.

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 attached to the gathering part 6 at the end of the corner 5" by fixing it with rivets 11 together with the reinforcing frames 5, 5', 5", and the corner reinforcing member 7 is The retaining pieces 8, 8', 8'' are integrally extended at the three points on the hem edge, and the two retaining pieces 8', 8'' are attached to the above-mentioned yz plane wall plate 2 and zy plane wall. The reinforcing frames 5, 5', 5'' are fixed to the inside of the intersection of the reinforcing frames 5, 5', 5'' in the plate 3 by means of rivets 12, and a stepped portion 13 is provided at the base end of each stopper piece 8, 8', 8''. 13 to the inner edge of each reinforcing frame 5, 5', 5'', and a metal contact plate 16 is brought into contact with the inner side of the intersection of the reinforcing frames 5 on the xy plane wall board 1, Reinforcing protrusions 17, 17' are provided on the two inner edges of this plate 16,
Similarly, the above-mentioned stopper piece 8 is attached to the corner near the intersection of the reinforcing frame 5.
A notch 18 having the same shape as , and gutter-like bent edges 19 and 19' are respectively provided on the two outer edges, and the notch 18 and the stopper 8 are fitted and the gutter-like bent edges 19 and 19' are reinforced. It is placed over the protrusions 15, 15' of the frames 5, 5', and each corner of the backing plate 16 other than the corner near the intersection of the reinforcing frames 5 is fixed with rivets 20, and the outer side of the backing plate 16 is A caster 22 is placed on the base plate 16, and several rivets 2 are attached to the reinforced part of the caster 22 by the above-mentioned backing plate 16.
3, and one of the rivets 24 of the rivets 23 in the fixing, and the notch 18.
A retaining piece 8 fitted with the above is fixed to the xy plane wall plate 1.

As described above, the outer edges of the xy plane wall plate 1, the yx plane wall plate 2, and the zy plane wall plate 3 are perpendicular to each other on the xyz line, and each orthogonal edge portion 4... The mold reinforcing frame 5, 5', 5'' is
In a case with a reinforcing frame, the corner reinforcing member 7 in the shape of a right pyramid covers the gathering part 6 at the end of the reinforcing frames 5, 5', 5''. , stop pieces 8, 8', 8'' are integrally extended at three locations on the hem edge of this corner reinforcing member 7, and a stepped portion 1 is provided at the base end of each stop piece 8, 8', 8''.
3, and the stepped portion 13 is connected to each reinforcing frame 5, 5',
5'' and the above-mentioned stop pieces 8, 8',
8″ to the above xy plane wall plate 1, yz plane wall plate 2 and
Since the reinforcing frames 5, 5', and 5'' are fixed to the inner side of the intersection of the xy plane wall board 3 with the rivets 12, 12, and 24, at least the retaining pieces 8, 8', and 8'' are fixed. This prevents the rivets 12, 12, and 24 from colliding directly with the floor or the like during the above-mentioned throwing and causing damage, thereby causing the rivets 11 to be damaged and the corner reinforcing member 7 and reinforcing frame 5 to be damaged. , 5', 5'' may lose their fixing function to the case body, or the rivets 1
This is not only effective in avoiding situations such as when the corner reinforcing member 7 loosens the clamping of the reinforcing frames 5, 5', and 5'' from the outside and causes looseness in the same parts. A metal backing plate 16 is brought into contact with the inner side of the intersection of the reinforcing frames 5 and 5' on the xy plane wall board 1, and gutter-like bent edges 19 and 19' are provided on two edges of this backing plate 16. The gutter-like bent edge 19,1
9′ is the protrusion 15, 1 provided on the reinforcing frame 5, 5′.
5', the corners of this plate 16 are fixed with rivets 20, and a caster 22 is placed on the outside of the plate 16, and the caster 22 is attached to the plate 16.
Since the rivet 23 and the rivet 24 are used to secure the castor 22 to the reinforced area and the fixing area of the stopper plate 8, the mounting part of the castor 22 can be sufficiently reinforced. The gutter-like bent edges 19, 1 are provided with trough-shaped bent edges 19, 19'.
9′ is the protrusion 15, 1 provided on the reinforcing frame 5, 5′.
5', so the backing plate 16 and reinforcing frame 5,
The overlapping part with 5' strongly reinforces the edge of the case body and more reliably supports the load applied to the same part, which in turn reduces the force applied to the xy plane wall plate 1.
This has effects such as being able to eliminate damage to the xy plane wall plate 1.
