[Action]

FIG. 1 shows the product in use, and the product is folded from this condition to the portable condition shown in FIG.

〔Example〕

The pair of left and right pipe leg rods 1, 1 are made to cross in an X shape when viewed from the side, and the crossing portion is pivotally attached by a pivot shaft 2 so that the pipe leg rods 1, 1 can be freely folded. Provided, the pipe rods 3, 3 are installed between the front left and right ends and the rear left and right ends of the pipe leg rods 1, 1, and a seat is seated between the left and right pipe rods 3, 3. 4 is stretched, and similarly, pipe-shaped armrest rods 5 are formed between the front left and right ends and the rear left and right ends of the pipe leg rods 1 and 1 with a pivot shaft 6 to pivotally attach the pipes. The armrest rods 5 made of 5 are provided so that they can be folded on the back side of the seat 4, and the backrest rods 7, 7 made of pipe are pivotally attached to the rear ends of the pipe armrests 5, 5 by means of pivot shafts 8. Pipe armrest rod 5,
5 is a foldable chair made of a pipe, which is provided so as to be foldable on 5, and a backrest sheet 9 is stretched on the pipe backrests 7, 7 and has a U-shaped connecting plate 10 and shaft holes 11 at both ends thereof. The pivotally projecting piece 12 is projected, the leg rod inserting rod 13 is integrally provided on the inner lower portion so as to project obliquely downward, and the bar rod inserting rod 14 is oriented at a right angle on one side of the connecting plate 10. Die-cast molding is performed on the joint a which is integrally provided, and shaft holes 16 are also formed at both ends of the U-shaped connecting plate 15, and a back rod insertion pipe 17 is integrally projected on the rear end. The installed joint b is also die-cast, and the four joint a are used to insert and secure the leg rod insertion rod 13 into the upper ends of the pipe leg rods 1 and 1, and the pipe rod insertion rod 14 to the pipe. It is inserted and fixed in the front and rear ends of the steel bar 3, and the lower end of the arm arm 5 made of pipe is inserted between the pivoting projections 12 and pivoted by the pivot shaft 6. Similarly, using the four joints b, the lower end of the pipe back rod 7 is inserted into the back rod rod insertion pipe 17 and fastened, and the pipe back rod 5 of the pipe back rod 5 is fixed between the U-shaped connecting plates 15. The front and rear end portions are fitted and pivotally attached by a pivot shaft 8 to form a folding chair body A.

The pipe leg rods 1, 1, the pipe bar rods 3, 3, the pipe armrest rods 5, 5, and the pipe back rods 7, 7 are lightweight type chairs when aluminum pipes are used, but other iron pipes , Stainless steel pipe, etc. may be used.

Although the seats 4 and the backrest seats 9 are cloth sheets, vinyl sheets or the like may be used.

The joint a and the joint b are made of aluminum die cast, but may be made of plastic using a plastic material having strength.

In the figure, 18 is an armrest cushion, and 20 is an insertion part of a backrest seat.

Since the present embodiment is configured as described above, in assembling the folding chair body A, the joints a and b are used and one of the joints a is used to make the pipe leg 1, the pipe armrest 5, and the pipe. Since the foldable chair body A can be easily assembled in a short time by connecting the bar 3 and the pipe armrest 5 and the pipe back rod 7 by the other joint b, the folding chair body A can be easily assembled. The work will be streamlined, and the products will be mass-produced and provided at low cost.

Since the joints a and b themselves are also molded products, they are uniform parts, and there is no variation in accuracy, which facilitates assembly and further mass production.

Further, since the joints a and b are also strong in strength, they can withstand a large load sufficiently, and have excellent practical effects such as providing a durable folding chair that is used durable. Is.

[Effect of device]

Since the present invention is configured as described above, the pipe backrest rods 7, 7 are folded over the pipe armrest rods 5, 5 for folding and storing, the pipe leg rods 1, 1 are folded, and the pipe armrests are also folded. Rotate the rods 5 and 5 to the outside to the left and right to arrange them on the back side of the seat 4 and fold them in a flat shape with the pipe bars 3, 3 as the upper end. The upper end of this flat product The hand-held suspension portions 19 are arranged in the length direction of the pipe-shaped rods 3 and 3 on the pipe-shaped rods 3 and 3 located in the section. Simply hold the hand-held suspension portion 19 in this hand to It will be a pipe foldable chair with excellent practicality that can be easily carried and moved while being flatly folded.
