BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a stackable chair in which a backrest is folded.

[0002]

2. Description of the Related Art Stackable chairs and folding chairs which are convenient to store and carry are well known. However, in these conventional products, the following inconveniences occur because the backrest remains in the upright state. In meetings and the like, many rows of long tables are arranged vertically, and when chairs are arranged on this table, the backrest and rear legs are exposed from both sides between the tables, so that it is not obstructed by traffic.

For this reason, there is a defect in terms of effective use of space, such as an extra space is required because a wide passage is required.

[0003]

SUMMARY OF THE INVENTION In the present invention, the above-mentioned drawbacks are intended to be improved by folding the backrest of the stackable chair.

[0004]

Means for Solving the Problems The lower ends of a pair of vertical front legs (1) having an interval of the seat width are lower end portions curved outward,
Connect this part to the lower end of the rear leg (2) wider than the front leg (3)
With the front seat support rod on the upper row of the left and right front legs.
(4) is attached, the upper end extends rearward diagonally upward to form a backrest receiving portion (5), and the upper ends of the left and right rear legs (2) are bent in an inverted U shape to form a pair of right and left backrest mounting portions. (6) is formed, a connecting portion connecting the mounting portion is a rear seat supporting rod (7) corresponding to the seat supporting rod (4), and a plurality of mounting plates ( 8), fix the seat (10) to this with screws (9), and fix the backrest mounting bracket (13) to the lower part on both sides of the backrest (11) with screws (12). (14), and the shaft is provided in the insertion hole (1) provided in the backrest mounting portion (6).
5) is foldably inserted, and a nut (16) is screwed to the shaft end to obtain a required chair (17).

[0005]

[Function] Since the present invention has the above configuration, the backrest (1
When 1) stands up, it is stable because it is supported by the backrest receiving part (5). When the backrest (11) is folded, the user can easily fold the backrest (11) by gripping the upper end of the backrest and pushing it forward, using the mounting shaft (14) as a fulcrum. The folded chair can be stored under the table (18). Further, since the distance between the pair of rear legs (2) of the chair is wider than that of the seat (10), the chair can be stored in any number of layers.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring to the drawings, one embodiment of the invention will be described with reference to the drawings. The lower ends of a pair of vertical front legs (1) having an interval of a seat width are curved lower ends, and the rear legs are wider than this portion and the front legs. Connect the lower end of (2) with the connecting part (3), attach the front seat support rod (4) to the upper part of the front legs on both left and right, and extend the upper end of the front leg (1) diagonally upward and rearward. A backrest receiving portion (5) is formed, and the upper end of the rear leg is bent in an inverted U shape to form a pair of right and left backrest mounting portions.
(6), the connecting portion of the mounting portion is a rear seat supporting rod (7) corresponding to the front seat supporting rod, and the seat (10) is a plurality of mounting plates provided on each supporting rod. (8) is fixed with screws (9), and the backrest (11) is attached with the mounting shaft (14) provided at the center of the outside of the mounting bracket (13) fixed with screws (12) on both sides of the lower stage. A required chair (17) is obtained by foldably inserting into an insertion hole (15) provided in the section (6) and screwing a nut (16) to a shaft end.

[0007]

[Effects of the Invention] As described above, the present invention allows the backrest to be easily folded, and the folded chairs can be stored under the table of the desk or the meeting room. There is no difficulty in walking and there is an advantage that the space can be used effectively. Also, when storing, it is convenient because it can be stacked. In addition, there is an advantage that the product is inexpensive because the structure is simple.
