Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a chair that is suitably used as a reception chair or the like that is stored in a stacked manner.

[Prior Art] The bottom of a seat covered with an upholstery material is generally comprised of a seat plate made of a relatively rigid material such as wood. However, since such a seat plate is covered with an upholstery material and cannot be directly seen or touched from the outside, only the minimum required molding process is performed. That is, in the conventional chair seat, as shown in a side cross section in FIG. 3, the front edge of the seat plate 22 has an angular shape. Upholstery material 21 is provided on the outside.

[Problems to be Solved by the Invention] However, since the upper surface of the front edge of the seat, including the front corners, is not protected by the legs or backrest, there is a high possibility that external objects will directly collide with it. However, if a hard object hits the front edge of the seat,
The upholstery will be squeezed between the collision object and the angular front edge of the seat plate, and concentrated stress will be applied to the upholstery, making that part likely to break. There's a problem.

Particularly in reception chairs and the like designed to be stacked and stored when not in use, the breakage of the top material is noticeable.
That is, in this type of chair, as shown in FIG. 4, a large number of chairs are stacked by repeating the process of placing the next chair from the front side on top of the chairs that have already been stacked. At this time, the tips of the chair legs 20 to be placed tend to collide with the front edges of the chair seats 10 that are already stacked. Therefore, in this type of chair, early breakage of the upholstery at the front edge of the seat frequently occurs, which is a serious problem.

In particular, in this type of chair, the tips of the two left and right legs 20 of the chair to be placed are placed at the front edge corners of the seats 10 of the chairs that are already stacked in the posture shown in FIG. The frequency of collisions is high,
There is a problem in that the covering material is likely to break at this portion.

The present invention aims to solve these problems.

[Means for Solving the Problems] In order to achieve the above object, the present invention provides a chair in which the bottom of the seat is made of a cushion material covered with an upholstery material, and the bottom of the seat is formed of a flat seat board. A chamfered portion is continuously formed on the upper surface of the front edge including the front corner portion to eliminate angularity, and a space is formed between the chamfered portion and the lower surface of the cushion material. There is.

[Function] With this structure, even if a hard object collides with the front edge of the seat, the upholstery will not be locally compressed between the colliding object and the seat plate. It's over. Therefore, it is possible to effectively avoid applying concentrated stress that could lead to breakage to the covering material.

In particular, the chair of the present invention has a chamfered part on the front edge corner of the seat, so when stacking,
Even if the left and right leg tips of another chair collide, the upholstery will not be intensively compressed between the leg tips and the upper surface of the angular front edge of the seat, which will prevent the chair from breaking. can be prevented.

Furthermore, since the chamfered portion and the lower surface of the cushion material are not attached and a space is formed between them, the provision of the chamfered portion imposes a restriction that the cushion material must be made into a special shape. Instead, a cushion material with a flat bottom surface can be used as before. Moreover, by doing this, the cushion material is no longer restrained by the seat plate at the front edge of the seat, and can be deformed not only in thickness but also in bending, so the front edge of the seat can be deformed more softly. It also alleviates the feeling of pressure on the legs of the seated person, which tends to occur at the front edge of the seat, and further enhances the feel when using the seat.

[Example] An example of the present invention will be described below with reference to FIGS. 1 and 2.

The chair of this embodiment is used, for example, as a reception chair, and as already shown in FIG. 4, it is constructed so that a large number of chairs can be stacked compactly and stored.

As shown in FIGS. 1 and 2, the seat 1 of this chair is equipped with a cushion material such as urethane on the top surface of a seat plate 12 that forms the bottom of the seat 1 to be installed on legs 2.
3, and an upholstery 11 made of cloth, synthetic resin, or the like is placed over it, and the upholstery 11 is secured to the back surface of the seat plate 12 with tassels 14. On the upper surface of the front edge of the seat plate 12 including the front corner portion 12b, a chamfered portion 12a that slopes toward the front of the seat 1 continues to extend to the side edge supported by the leg 2. It is formed as follows.

Therefore, this chamfered portion 12a and the cushion material 1
A space S is formed between the lower surface 13a of 3 and the lower surface 13a of 3.

When this chair is not in use, the front side of the legs 2 is held and the next chair is placed on top of the already stacked chairs, which is repeated, so that a large number of chairs are stacked and stored.

However, if the chair has seat 1 as described above, the tips of relatively hard legs 2 may collide with the front edge of seat 1 during stacking, or other hard objects may collide with the front edge of seat 1. Even if there is a collision, the upholstery 11 will not be locally pinched between the colliding object and the seat plate 12. Therefore,
No concentrated stress is applied to the upholstery 11, and early breakage of the upholstery 11 at the front edge of the seat 1 can be effectively prevented. Furthermore, when the upholstery 11 is fixed to the back surface of the seat 1, the front edge is not sharp, so it will not break during the assembly stage.

Note that the present invention is not limited to the embodiments described above, and various modifications can be made without departing from the spirit of the present invention.

[Effects of the Invention] Since the present invention has the above-described configuration, it is possible to provide a chair that can effectively prevent early breakage of the upholstery.

In particular, the present invention has a chamfered part on the front edge corner of the seat, so even if the left and right leg tips of other chairs collide when stacked, the leg tips and the seat plate will not overlap. The top covering material is locally compressed between the top surface side of the angular front edge and can be effectively prevented from being broken due to impact. Therefore, even though it is equipped with a flat plate-shaped seat plate that is easy to manufacture, the upholstery is not easily damaged even after repeated stacking.
This makes it possible to dramatically improve durability without difficulty.

In addition, since a space is formed between the chamfered portion and the lower surface of the cushion material, there is no restriction that the cushion material must be made into a special shape due to the provision of the chamfered portion. A cushion material with a flat underside can be used. Therefore, no complications are caused in manufacturing the cushion material. In addition, by doing this, the cushion material is more likely to deform at the front edge of the seat, which alleviates the feeling of pressure on the legs of the seated person that tends to occur at the front edge, further enhancing the feel when using the seat. You can also do it.
