Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a chair with a seat plate and an armrest that can be freely attached, and in particular, an object of the present invention is to provide a chair in which the seat plate and armrest can be easily attached and assembled. be.

Embodiments of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a perspective view of an example of a pine surge chair constructed by incorporating a chair pine surge device according to an embodiment of the present invention.
A backrest 10 is attached to the backrest 10, a cushioned seat plate 2 is fixed on the frame 1 in front of the backrest 10, and the frame 1 is fixed on both sides of the seat plate 2.
Armrests 4, 4 are erected against the vehicle. The backrest 10 is pivotally supported on the frame 1 by a shaft 11, and the lower end of the backrest 10 and the frame 1
1, the backrest 10 is rotated relative to the frame 1 by operating a reclining lever 13, which is connected to the front part of the reclining lever 10 by a gas spring 12, and which operates a valve mechanism (not shown) within the gas spring 12. It has a reclining function. The seat plate 2 has a shape so as to be placed on the frame 1, and has convex portions 7, 7 that protrude laterally at the center on both sides. Frame 1 when plate 2 is placed
The receiving pipe 6 is placed upright between the pipes 6 and 6. As shown in the figure, a pair of receiving pipes 6 are provided upright on both sides of the frame 1, and one of each pair of receiving pipes 6 is formed to have an oval pipe hole. The receiving pipes 6 are provided with slots 14. The pair of armrests 4, 4 are formed with upper end edges as shoulder rests 3, 3, and recesses 5, 5 in the lower ends of their opposing inner surfaces. The insertion pipes 8, 8 are arranged in a downwardly hanging manner. By fitting these insertion pipes 8 into the receiving pipes 6, the armrest 4 is erected with respect to the frame 1, and at the same time, the convex portion 7 of the seat plate 2 is placed above the recess 5 as shown in FIG. It is press-fixed by the edge, and since the slot 14 is formed in the receiving pipe 6, the insertion pipe 8 can be press-fitted to eliminate wobbling when attaching the armrest 4, and each pair Since the pipe hole of one of the receiving pipes 6 is oval, it is possible to absorb errors in the mounting pitch of the insertion pipe on the armrest 4 side.

Furthermore, in the above embodiment, a pair of hook holes 15 are formed in the lower part of the insertion pipe 8 in the diametrical direction, and the hooks 9a of the clip 9 protrude from the hook holes 15 so as to be freely retractable. In each of both armrests 4, a hook hole 15 is drilled in a direction parallel to the armrest 4 for one insertion pipe 8, and a hook hole 15 is bored for the other insertion pipe 8 corresponding to the oval receiving pipe 6. A hook hole 15 is bored in a direction perpendicular to the armrest 4.
FIG. 5 shows a U-shaped clip made of an elastic material such as plastic, and has hooks 9a, 9a at the upper end, which are inserted through the aforementioned hook holes 15. A clip 9 is detachably attached to the lower end of the insertion pipe 8 so as to protrude freely and retractably, and the hooks 9a, 9a are inserted into the hook holes 15, 1 as shown in FIG. 6a.
When the insertion pipe 8 is inserted into the receiving pipe 6 and the hook hole 15 portion protrudes from the lower end of the receiving pipe 6, the hooks 9a, 9a protrude from the hook holes 15, 15, and these hooks 9a,
9a is locked to the lower ends of the receiving pipes 6, 6 to prevent them from coming off. Note that FIG. 7 shows an example of the configuration of the armrest 4, in which a cover 17 is attached to a core material 16 of a hollow molded product with a set screw 18, and a cushion 19 is fixed with a tension material 20, so that the arm rest 4 is attached to the arm rest 3.
The insertion pipe 8 is fixed to the core material 16 with a fixing screw 21.

As described above, in the present invention, a connecting fitting is arranged in the recess formed in the lower end of the opposing inner surface of the armrest, and the receiving pipe on the frame side is connected to the connecting fitting. Therefore, the armrest is attached to the frame. The connecting member for erecting the seat plate is not visible from the outside, giving it a good appearance and ease of assembly.Moreover, the protrusions on both sides of the seat plate fitted into the recess are connected to the upper edge of the recess. Since the seat plate is fixed with a presser foot, the seat plate can be fixed at the same time by simply placing the seat plate on the frame and then fixing the armrest upright on the frame, which greatly improves the ease of assembly. It has the effect of providing improvement.

[Brief explanation of the drawing]

Fig. 1 is a perspective view of an embodiment of the present invention, Fig. 2 is an exploded perspective view of the same, Fig. 3 is an enlarged top view of the main part of the frame of the above, and Fig. 4 is a presser fixing the protrusion of the seat plate of the above. Fig. 5 is an enlarged perspective view of the same clip as above, Fig. 6 a and b are enlarged sectional views of main parts during insertion of the insertion pipe and when the connection is completed, Fig. 7 is an enlarged sectional view of the main part of the same as above.
