Abstract

An assembled structure includes a joint member including a first opening arranged on a first surface, a second opening arranged on a second surface adjacent to the first surface, and a third opening arranged on a third surface adjacent to the first surface and arranged at a position corresponding to the second surface, a first frame member inserted into the first opening and having a first convex portion at an end portion in a longitudinal direction, a second frame member inserted into the second opening and having a second convex portion at an end portion, and a fixing member inserted into the third opening and fixing the first frame member and the second frame member.

Claims (58)

1 . An assembled structure comprising:

a joint member including a first opening arranged on a first surface, a second opening arranged on a second surface adjacent to the first surface, and a third opening arranged on a third surface adjacent to the first surface, the third surface arranged opposite the second surface;

a first frame member axially inserted into the first opening and having a first convex portion at an end portion in a longitudinal direction;

a second frame member inserted into the second opening and having a second convex portion at an end portion; and

a fixing member different from the joint member and inserted into the third opening and fixing the first frame member and the second frame member, wherein

the third opening is arranged opposite the second opening,

the first convex portion protrudes in a direction intersecting the longitudinal direction,

the fixing member has a first concave portion at an end portion, and

the first concave portion and the first convex portion engage.

2 . The assembled structure according to claim 1 , wherein the joint member has a hexahedral structure.

3 . The assembled structure according to claim 1 , wherein the third opening is arranged opposite the second opening.

4 . The assembled structure according to claim 1 , wherein the first convex portion of the first frame member is arranged corresponding to the first concave portion of the fixing member, and the first concave portion and the first convex portion are engaged.

5 . The assembled structure according to claim 1 , wherein one surface of the first convex portion and a side surface of the first concave portion are substantially parallel to each other.

6 . The assembled structure according to claim 1 , wherein

the joint member has a second concave portion provided in the third opening,

the fixing member has a third convex portion provided at an end portion on a first side of a side surface so as to correspond to the second concave portion, and

the second concave portion and the third convex portion engage with each other when the fixing member engages with the first convex portion.

7 . An assembled structure comprising:

a joint member including a first opening arranged on a first surface, a second opening arranged on a second surface adjacent to the first surface, and a third opening arranged on a third surface adjacent to the first surface, the third surface arranged opposite the second surface;

a first frame member axially inserted into the first opening and having a first convex portion at an end portion in a longitudinal direction;

a second frame member inserted into the second opening and having a second convex portion at an end portion; and

a fixing member different from the joint member and inserted into the third opening and fixing the first frame member and the second frame member, wherein

the third opening is arranged opposite the second opening,

the fixing member has a through hole in the direction of insertion into the third opening,

the second convex portion has a screw hole, and

the fixing member fixes the second frame member by inserting a screw into the through hole of the fixing member and the screw hole.

8 . The assembled structure according to claim 7 , wherein

the joint member has a first concave portion provided in the third opening,

the fixing member has a third convex portion provided at an end portion on a first side of a side surface so as to correspond to the first concave portion, and

the first concave portion and the third convex portion engage with each other when the fixing member engages with the first convex portion.

9 . An assembled structure comprising:

a joint member including a first opening arranged on a first surface, a second opening arranged on a second surface adjacent to the first surface, and a third opening arranged on a third surface adjacent to the first surface, the third surface arranged opposite the second surface;

a first frame member axially inserted into the first opening and having a first convex portion at an end portion in a longitudinal direction;

a second frame member inserted into the second opening and having a second convex portion at an end portion; and

a fixing member different from the joint member and inserted into the third opening and fixing the first frame member and the second frame member, wherein

the third opening is arranged opposite the second opening,

the second convex portion of the second frame member has a screw hole at a tip portion,

the fixing member has a screw portion arranged corresponding to the screw hole, and

the screw portion is inserted into the screw hole.

10 . The assembled structure according to claim 9 , wherein

the joint member has a first concave portion provided in the third opening,

the fixing member has a third convex portion provided at an end portion on a first side of a side surface so as to correspond to the first concave portion, and

the first concave portion and the third convex portion engage with each other when the fixing member engages with the first convex portion.

11 . An assembled structure comprising:

a joint member including a first opening arranged on a first surface, a second opening arranged on a second surface adjacent to the first surface, and a third opening arranged on a third surface adjacent to the first surface, the third surface arranged opposite the second surface;

a first frame member axially inserted into the first opening and having a first convex portion at an end portion in a longitudinal direction;

a second frame member inserted into the second opening and having a second convex portion at an end portion; and

a fixing member different from the joint member inserted into the third opening and fixing the first frame member and the second frame member, wherein

the third opening arranged opposite the second opening,

the fixing member has a notch arranged and extending at a position corresponding to the first surface of the joint member,

the first frame member has a columnar portion closer to a base side than the first convex portion,

the first convex portion protrudes in a direction intersecting the longitudinal direction,

a width of the notch is greater than a width of the columnar portion of the first frame member in the direction intersecting the longitudinal direction, and

the width of the notch is smaller than a width of the first convex portion of the first frame member in the direction intersecting the longitudinal direction.

12 . The assembled structure according to claim 11 , wherein

the joint member has a first concave portion provided in the third opening,

the fixing member has a third convex portion provided at an end portion on a first side of a side surface so as to correspond to the first concave portion, and

the first concave portion and the third convex portion engage with each other when the fixing member engages with the first convex portion.
