Abstract

A coupling member includes: first, second, and third portions each having a flat plate-like shape; and a fillet portion. The first portion has a first side and a second side orthogonal to each other. The second portion is bent at the first side relative to the first portion, and extends to an inner surface of the first portion. The third portion is bent at the second side relative to the first portion, and extends to an inner surface of the first portion. A bend radius of an outer surface of the coupling member at the first side is equal to a bend radius of a surface of a first extending member facing the first side. A bend radius of an outer surface of the coupling member at the second side is equal to a bend radius of a surface of a second extending member facing the second side.

First claim

The invention claimed is:

1. A housing comprising:
at least two extending members; and
a coupling member for coupling the at least two extending met bens to each other,
wherein the coupling member includes:
a first portion having a flat plate-like shape, the first portion having a first side extending straightly and a second side orthogonal to the first side and extending straightly;
a second portion having a flat plate-like shape, the second portion being bent at the first side relative to the first portion, the second portion extending perpendicularly to an inner surface of the first portion;
a third portion having a fiat plate-like shape, the third portion being bent at the second side relative to the first portion, the third portion extending perpendicularly to the inner surface of the first portion; and
a fillet portion having a flat plate-like shape, the fillet portion protruding perpendicularly to an inner surface of the second portion, the fillet portion being disposed to face the third portion,

wherein a bend radius of an outer surface of the coupling member at the first side is equal to a bend radius of a surface of a first extending member facing the first side, and
a bend radius of the outer surface of the coupling member at the second side is equal to a bend radius of a surface of a second extending member facing the second side
wherein each of the first portion, the second portion, the third portion, and the fillet portion is formed by a bending process onto a flat plate member, and
wherein each of the first portion, the second portion, the third portion, and the fillet portion is provided with at least one through hole for coupling the first and second extending members to the coupling member through rivet connection, the at least one through hole extending through a corresponding one of the first portion, the second portion, the third portion, and the fillet portion in a thickness direction.

2. The housing according to claim 1 , wherein
the coupling member couples three extending members to one another,
the second portion has a third side orthogonal to the first side and the second side and extending straightly,
the fillet portion is bent at the third side relative to the second portion and protrudes perpendicularly to an inner surface of the second portion, and
a bend radius of the outer surface of the coupling member at the third side is equal to a bend radius of a surface of a third extending member facing the third side.

3. The housing according to claim 2 ,
wherein the first extending member is a beam member extending in a horizontal direction, and
the third extending member is a pillar member extending in a vertical direction.

4. The housing according to claim 1 , wherein a space is formed between the second portion and the third portion.

5. The housing according to claim 1 ,
wherein the first extending member is a first beam member extending in a horizontal direction, and
the second extending member is a second beam member extending in the horizontal direction.
