The seat is generally provided with a synthetic resin seat plate, which is an integrally molded product, and a cushion material for convenience in processing and assembly, and the flat lower surface of the seat plate is rigid. It is designed to be supported on the upper surface of the seat.

の上面に座を配設したものでは、座受が座の下面側に大
きく突出するという不都合を生じ、外観的にすぐれたデ
ザインを採用することが難しくなる問題を生じる。However, it is often the case that a spring mechanism or the like for supporting the backrest is incorporated in the seat support. For this reason, when the seat is disposed on the upper surface of such a seat, there is a disadvantage that the seat greatly protrudes to the lower surface side of the seat, and it is difficult to adopt a design having an excellent appearance. Occurs.
【０００４】このような不具合に対処するために、座板
の下面中央に凹陥部を形成し、その凹陥部内に座受を没
入配置するようにしたものが考えられている。In order to cope with such a problem, it has been considered to form a concave portion in the center of the lower surface of the seat plate and to immerse the seat in the concave portion.

みを伴って肘が左右に傾動し易くなる。However, if a concave portion is formed in the center of the lower surface of the seat plate, the entire seat plate is likely to bend in the vertical direction unless the overall shape and the arrangement structure of the ribs are carefully designed. For this reason, in the type in which the elbows are attached to the right and left sides of the seat plate, it is difficult to increase the support rigidity of the elbow, and the elbow is likely to tilt left and right with the bending of the seat plate.

設けたことを特徴とする。That is, the chair according to the present invention, as shown in FIG. 1, has a seat 3 disposed on a seat receiver 2 supported by a leg 1 and an elbow 6 attached to the seat 3. It is.
The seat 3 includes a seat plate 32 made of synthetic resin.
A concave portion 32 in which the seat receiver 2 is buried under the seat plate 32.
a is formed, and base ends 61 of the elbows 6 are mounted on both left and right sides of the seat plate 32. Then, the concave portion 32a
Between the left and right sides of the seat 32 and the left and right sides of the seat 2 immersed in the recess 32a.
The right and left sides approach and separate from the left and right sides of seat 2
It is characterized in that an engaging portion 7 is provided which engages with concaves and convexes from the upper and lower directions in order to prevent the engagement.

And the like can be smoothly continuous with the lower surface. However, if the seat plate made of synthetic resin is simply provided with a recess, if the elbows are attached to the left and right sides of the seat plate, when an external force acts on the elbow, the entire seat plate will be on both sides of the recess. Warping,
The elbow is likely to be shifted outward or inward. On the other hand, according to the present invention, the left and right sides of the recess 32a and the seat
Is provided between the left and right side portions of the seat 2 so that the right and left inner side surfaces of the recessed portion 32a and the left and right outer side surfaces of the seat receiver 2 come into contact with and separate from each other. It can be prohibited by the joint 7. Therefore, the seat plate 32 bends up and down while the width of the left and right openings of the concave portion 32a fluctuates.
This can be suppressed by the presence of the seat 2. Therefore, the rigidity of the seat plate 32 can be increased, and the support strength of the elbow 6 can be improved.

る。With this configuration, when the seat receiver 2 is buried inside the seat 3, it is possible to reliably prevent the seat receiver 2 from protruding greatly below the seat 3, as shown in FIG. In this embodiment, in particular, the lower surface of the seat plate 32 and the seat
And the lower surface can be smoothly continued. For this reason, it is easy to adopt a design excellent in appearance. In such a configuration, when the external forces F 1 and F 2 act on the elbow 6, the entire seat plate 32 warps upward or downward, and accordingly, the elbow 6 is displaced outward or inward. Easier to do. On the other hand, according to the present embodiment, since the engaging portions 7 are provided between the left and right side portions of the recessed portion 32a and the left and right side portions of the seat receiver 2 so as to fit into the concave and convex from the up and down direction. The engagement between the left and right inner surfaces of the portion 32a and the left and right outer surfaces of the seat receiver 2 can be prevented by the engaging portion 7. Therefore, the seat plate 32 can be suppressed from flexing up and down while the width of the left and right openings of the recessed portion 32a varies with the presence of the seat receiver 2. Therefore, the rigidity of the seat plate 32 can be increased, and the support strength of the elbow 6 can be reliably improved.

It may be formed by a direction engaging element. Further, the seat receiver 2 does not necessarily need to be completely buried in the concave portion 32a of the seat plate 32, and may be partially buried. Further, the seat 2 is not limited to a synthetic resin, but may be a metal die-cast made of aluminum, zinc, or the like. Other configurations can be variously modified without departing from the spirit of the present invention.

る。 As described above, the chair according to the present invention has the above-mentioned structure. By burying the seat in the recess formed in the lower surface of the seat plate, the seat greatly protrudes below the seat. This can be reliably prevented, and a design excellent in appearance can be adopted. Moreover, even if an external force acts on the seat plate provided with such a concave portion through the elbow, the bending of the seat plate can be effectively prevented at the engaging portion, so that the rigidity of the seat plate can be maintained at a high value while maintaining the rigidity of the seat plate at a high value. Can be improved in stability. That is, the engaging portion is located on the left of the concave portion.
The right and left sides approach and separate from the left and right sides of the seat
It is provided in order to prevent the problem. Therefore, on the elbow
The outwardly acting outward force causes the seat plate to bend upward and
The left and right sides of the part and the left and right sides of the seat
Can not only suppress the introvert acting on the elbow
The seat plate bends downward due to the external force of
Also prevents the left and right sides of the seat from separating
be able to. Therefore, by increasing the rigidity of the seat plate,
Support stiffness can be comprehensively improved without difficulty.
