という問題があつた。 Conventional folding chairs have been folded by connecting the front and rear legs with a hinge, but if armrests are attached to the backrest of such a folding chair, the armrests will not move away from the backrest when the chair is folded. There was a problem in that the armrests remained protruding forward and became a hindrance when storing or transporting the chair.

あつた。 A pipe chair as shown in Japanese Utility Model Publication No. 44-24983 has recently been proposed as a folding chair with armrests to solve this problem. In this pipe chair, the lower end of the rotating rod is rotatably supported by the rear legs, and the rear part of the seat is rotatably supported by the upper end of the rotating rod, and the upper end of the rotating rod is rotatably supported. As a result, the seat and backrest are folded close together. However, since this pipe chair supports the rear part of the seat via a freely rotatable rotating rod, when the upper end of the rotating rod is located behind the lower end of the rotating rod, the lower part of the backrest or the seat If weight was applied to the rear part, the rotating rod would rotate and fold up carelessly, creating a safety problem.

うにしている。 In the figure, reference numeral 1 denotes a rear leg, and this rear leg 1 is connected to the upper end of a front leg 2 by a hinge 3 at a position below the upper end of the rear leg 1 at a required length. As shown in Figure 2, the hind legs 1
The upper part of the front leg 2 extends obliquely upward from the rear to the front from the connection point with the front leg 2. In order to connect the rear leg 1 and the front leg 2, in this embodiment, the hinge 3 is attached inside the rear leg 1 and the front leg 2.
This is done so that it will not be exposed and make you look bad. 4
is a seat part, and this seat part 4 is rotatably attached to the front leg 2 with a pin 5 at a position on its side, and at the rear thereof, a locking rod 6 projecting laterally is attached upwardly to the inner surface of the rear leg 1. , is installed by being fitted into a guide groove 7 recessed along the downward direction,
This prevents the front legs 2 and the rear legs 1 from opening too much. Reference numeral 8 denotes a backrest, and the lower end of the side frame 9 of the backrest 8 is attached to a position at a required height on the back side of the rear leg 1 with a hinge 10. Also in this case, the hinge 10 is attached inside the rear leg 1 and the side frame 9 so as not to be exposed. Reference numeral 11 denotes a hinge type connecting member attached from the upper end of the rear leg 1 to the side frame 9 of the backrest 8, and an armrest 12 is attached on top of this connecting member 11. Here, the connecting member 11 is made up of a front member 13 and a rear member 14 connected by a pin 15, and in this embodiment, an armrest 12 is attached to the front member 13.
2 on the rear member 14, or attach the armrest 1 on the rear member 14.
It is also possible to cut 2 at the center and separately attach them to the respective members 13 and 14. Further, in this embodiment, the rear member 14 is formed in a concave shape to prevent fingers from being jammed between the rear member 14 and the armrest 12.

場合はこれと逆の手順で行なう。 When folding the armrest folding chair with such a configuration, when the backrest 8 is rotated forward and the armrest 12 is rotated and lifted forward, the hinge type connecting member 11 is connected to the pin 15 as shown in FIG. At the position, the front member 13 and the rear member 14 are bent into a mountain shape, and when the backrest 8 is further rotated forward and the side frame 8 of the backrest 8 is brought into contact with the back side of the rear leg 1, the connecting member 11 is bent. is bent at a more acute angle, and the armrest 12 becomes parallel to the rear leg 1 and comes into contact with the front side of the rear leg 1 (see Figure 3). When the front legs 2 are rotated backward in this state, the locking rod 6 of the seat 4
moves downward along the guide groove 7, the seat 4 rotates upward, and when the front legs 2 are in contact with the rear legs 1, the seat 4 becomes substantially in a straight line above the front legs 2, as shown in FIG. A folding chair with armrests can be folded into a board.
If you want to return this folding chair with armrests to its original state, follow the steps in reverse.

る。 As detailed above, in the folding chair with armrests according to this invention, when the backrest is rotated forward and the armrests are lifted forward so as to rotate, the hinge-type connecting member is folded into a chevron shape, and the backrest is placed on the back side of the rear legs. When they touch, the armrests become parallel to the rear legs and touch the front side of the rear, and the armrests are folded against the backrest, making it easier to store and transport without only the armrests protruding forward like in the past. This eliminates the need for the armrests to get in the way, and because the rear legs of the seat directly support the seat in a rotatable manner, it is extremely safe.
