Description

[Detailed Description of the Invention] The present invention relates to a folding chair that can be easily opened and closed, and can be folded compactly.

Embodiments of the present invention shown in the drawings will be described in detail below. Reference numeral 1 denotes a front leg body formed by bending a metal pipe or a metal rod into a shape and curving it at approximately the middle position between the upper and lower sides.On both sides of the front leg body, there are screw holes 2 that open inward at appropriate positions in the middle part. 2
Fitting holes 3, 3 opening inward are formed at positions appropriately spaced downward from the fitting holes 3, 3, respectively.
Reference numeral 4 denotes a rear leg body formed by bending a metal pipe or a metal rod into a shape, and through holes 5, 5 are formed on both sides of the rear leg body at appropriate positions in the middle. The front and rear leg bodies 1 and 6 are assembled by sequentially inserting the through hole 5 and the washer 7 from the inside and screwing them into the screw hole 2 with the front and rear leg bodies 1 and 4 intersecting each other at an intermediate position. 4 is a screw shaft that is mutually rotatably supported. Reference numeral 8 denotes a plurality of wooden seat members provided at the front part of the rear leg body 4, which are fixed with a plurality of screws 8' or the like. Reference numeral 9 denotes a support shaft which holds the seat part attached to the rear leg body 4 when the legs are opened by inserting both ends into the fitting holes 3, 3 of the front leg body 1. The support shaft 9 is inserted into the fitting holes 3, 3 by pushing the front leg body 1 apart to the left and right. 10 is a backrest made of cloth and has cylindrical parts 11, 11 whose upper ends are closed on both sides,
The cylindrical parts 11, 11 are installed by covering the upper ends of both sides of the front leg body 1. Numeral 12 is a stopper A provided below the rear leg body 4 which, when the leg is closed, engages with a stopper B13 provided on the front leg body 1 to prevent the leg from opening after folding and during transportation. Reference numerals 14 and 14 denote rubber feet fitted onto the front and rear leg bodies 1 and 4.

Next, the order of assembling the folding chair configured as described above will be explained. Spread the front leg body 1 to the left and right and insert the fitting holes 3, 3.
After fitting both sides of the support shaft 9 to the bottom, the rubber feet 14, 14 are fitted to the lower part, and the stopper B13 is fitted. Next, a plurality of seat members 8 are attached to the front left and right sides of the rear leg body 4 on which the rubber feet 14, 14 and the stoppers A12 are fitted, using screws or the like with appropriate gaps. Then, before
The rear leg bodies 1 and 4 are crossed so that the screw holes 2 and 2 match the through holes 5 and 5, and the screw shaft 6 is screwed into the screw hole 2 after sequentially inserting the through hole 5 and the washer 7. As a result, the front and rear leg bodies 1 and 4 are pivotably supported relative to each other. Finally, the chair is completed by attaching the backrest 10 to the upper end of the front leg body 1 with the cylindrical parts 11, 11.

As the chair is assembled in this way,
No tools are required for the assembly, and it can be easily assembled at home. Further, the chair can be disassembled by reversing the above-mentioned assembly order.

FIGS. 1 and 2 show the chair in the open leg state. In this state, the front part of the rear leg body 4 having the seat body 8 is supported by the support shaft 9, so that it is difficult to sit on the seat body 8. The weight applied to this part when hanging is received by the support shaft 9, and the front and rear leg bodies 1,
This ensures that the predetermined leg-spread state of No. 4 is maintained. Furthermore, since the backrest 10 is made of cloth, the back is stable and is extremely comfortable to use for long periods of time.

The chair is folded by rotating the rear leg body 4 with respect to the front leg body 1.
This is done by holding the front and rear leg bodies 1 and 4 with the arms 2 and 13 and closing the legs.

The materials for the front and rear leg bodies 1, 4, the seat body 8, and the backrest 10 are not limited to those mentioned above, and can be selected arbitrarily.

Since the folding chair of the present invention has the above-mentioned configuration, the front leg body, backrest, seat body, and rear leg body can be easily formed into simple shapes, and this type of folding chair tends to be complicated. Even in the area where the hind leg body and the seat body are connected, it is only necessary to attach the seat body to the hind leg body, and moreover, the predetermined leg position can be maintained by using the support shaft of the front leg body, so it is structurally simple. It is extremely simple to operate, and furthermore, the stopper can reliably maintain the closed state of the legs, which is extremely useful in practice.
