Description

[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a mounting structure for a cushion used on the seat or backrest of a chair or the like.

(Prior Art) Conventionally, a cushion made of plastic foam or cotton is placed on the seat or back of a chair, the upper surface of which is covered with a covering material such as leather or woven fabric, and the cushion is fixed to a mounting plate.

However, there is a drawback that the cushion sandwiched between the upholstery and the mounting plate shifts from its predetermined position after long-term use. For this purpose, for example, there is a method in which a through hole is provided at a predetermined location in the cushion, and this is fixed using fastening means such as a bolt or screw with a washer inserted directly into the mounting plate that is assembled to the frame. In this case, a strong tightening force is applied only to the fastening part of the cushion, which causes cracks in the cushion hole part and easily damages the cushion.Also, since there is virtually no cushion part at the fastening part, no cushion effect can be expected. There were problems such as.

Incidentally, in recent years, seats or backrests have become integral structures in which a cushion layer of polyurethane foam or the like is directly formed on the back surface of an upholstery material using a vacuum forming method or the like.

In such cases, to secure the upholstery with cushions to the mounting plate, use another frame to secure the periphery of the upholstery and the mounting plate, or fix the upholstery from the top surface using fastening means. However, it had the drawback of being restricted in terms of design.

(Purpose of the invention) The present invention is intended to solve the problems of the conventional method, and by reinforcing the periphery of the cushion and fitting the cushion and its mounting member with one touch, the invention can be used as a seat or backrest of a chair. An object of the present invention is to provide a cushion mounting structure that can perform the following functions.

(Structure of the invention) In order to achieve the above object, the present invention exposes a wire buried around a cushion of a chair or the like through a plurality of recesses provided in the cushion, and attaches appropriate fittings to the periphery of the cushion mounting member. The cushion and the mounting member are assembled by fitting each mounting tool into the exposed wire rod. With this configuration, the cushion can be reinforced without exposing any protrusions to the outside by embedding the wire in the perishable periphery of the cushion covered with the covering material.

Moreover, the cushion and the cushion mounting member can be fitted and assembled with one touch using the mounting tool.

(Example) Embodiments of the present invention will be described based on the drawings.

FIG. 1 shows a backrest 1 of a chair, which is composed of two members: a cushion 2 and a mounting member 3. As shown in FIG.

The cushion 2 is made of foamed polyurethane, and its surface is covered with a covering material 4 such as leather.An arch-shaped steel wire 5 is buried on the inner periphery of the cushion 2, and the cushion is wrapped so that the steel wire 5 is exposed. 2 is provided with an appropriate number of recesses 6.

These can be integrally molded using a vacuum forming method or the like.

Further, as shown in FIG. 2, the mounting member 3 is provided with a mounting tool 7 at a predetermined position on the peripheral edge that fits into the recess 6, and when the mounting tool 7 is inserted into the recess 6, the cushion 2 The steel wire 5 is fitted into the exposed steel wire 5 in a plurality of recesses 6 provided in the holder.

The mounting tool 7 (see Fig. 3) is made of synthetic resin, and its holding part 7a has a groove part 8 fitted into the edge part 3a of the mounting member 3 from the side, and a steel wire is attached to the outside of one side of the holding part 7a. A grip portion 9 having a C-shaped cross section is integrally provided to be fitted into the grip portion 5 . The opening 10 of each gripping part 9 is arranged parallel to the steel wire 5 to be fitted.

The assembly of the backrest portion 1 constructed in this way will be explained together with its operation.

A cushion 2 whose surface is covered with a covering material 4 has a steel wire 5 buried therein, and a recess 6 where the steel wire 5 is exposed. In order to fit the position of this recess 6,
The mounting tool 7 is inserted into the edge portion 3a of the mounting member 3.

When the cushion 2 is fitted to the mounting member 3, the opening 10 of the C-shaped grip 9 provided on the synthetic resin fixture 7 is elastic, so it is pressed by the steel wire 5 and expands. 7 and the steel wire 5 are fitted together.

This fixture 7 is simply fitted into the mounting member 3 when the cushion 2 is not attached to the mounting member 3, but once it is fitted to the steel wire 5 inside the cushion 2, its movement is restricted. , the mounting member 3 and the cushion 2 are firmly fixed.

(Effects) As explained above, according to the present invention, by embedding steel wires in the inner periphery of the cushion, the easily damaged periphery can be reinforced, and there is no need to use other fasteners on the surface of the cushion. This is advantageous in terms of design and can fully exhibit the cushioning effect.

Furthermore, at the back end of the periphery of the cushion, there is usually a joint between the covering material and the cushion, or a folded part of the covering material, but since the steel wire is embedded in the cushion, this occurs when the cushion is assembled to the mounting member. Then, the attachment member sinks into the cushion and acts to cover the joints, etc., and the edge portion of the attachment member is also wrapped by the cushion. Therefore, it is possible to eliminate the trouble of using another band-shaped frame to fix the edge portion as in the conventional case.

In other words, the work of assembling the cushion to the mounting member becomes simple and easy.
