DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to furniture in which a wall material is devised.

[0002]

2. Description of the Related Art There are moving furniture such as chairs and wagons in which moving means such as casters are attached to the lower surface of a furniture body and used at appropriately changed places of use. Conventionally, in general furniture including such moving furniture, the wall material forming the outer wall of the furniture main body is generally formed of a metal plate such as a steel plate.

[0003]

However, if the wall material is made of a metal plate such as a steel plate, the user's feet or the like come into contact with each other to generate a collision sound, and at that time, the wall material becomes plastic. There have been problems such as deformation, the appearance is damaged, and the user feels pain at the time of collision due to lack of cushioning effect. In particular, some people feel extremely unpleasant about the metal sound generated when metal comes into contact with others. In addition, there are disadvantages such as a cold and unpleasant contact sensation at the time of contact, and the appearance of the whole furniture feels inorganic. In particular, in the case of mobile furniture that is frequently moved and used, there are extremely many opportunities to come into contact with the user or other furniture as compared with ordinary furniture that is fixedly used. Therefore, in the case of moving furniture, especially in the case of moving furniture, including the problem that the furniture comes into contact with and damages other furniture when moving, the above-described problems are more remarkable than ordinary furniture.

[0004]

In order to solve the above-mentioned problems, the furniture of the present invention employs a synthetic resin material provided with a cushion layer on a wall material.

[0005]

[0006] With such a structure, even if it comes into contact with the user or other furniture, no loud collision sound is generated, and since there is a shock absorbing function of absorbing shock, other furniture and other furniture are used. Not only is it difficult for people to be hurt, but it is also difficult for plastic deformation. Furthermore, there is no cold and unpleasant contact sensation unlike a metal plate, and the contact sensation is good, and the appearance of the furniture as a whole is warm without being inorganic. Moreover, if the material is made of a synthetic resin, a hinge for attaching the wall material to the furniture body can be formed integrally with the wall material. By providing such a hinge portion, the fastening portion can be formed. Can be folded to a position that is not visible from the outside to improve the appearance, and compared to the case where the wall material is fixed to the furniture body without bending, the wall material may be stretched or external force may act on the wall material In such a case, an excessive force is not applied to the fastening portion, and a simple fastening tool such as a one-touch clip can be used.

In a preferred embodiment, the furniture body is
It has backup material, and this backup material has wall
Some of them are attached to some of the materials.
You. In a preferred embodiment of the wall material, the wall material forms a curved outer wall by fixing at least both side ends thereof to the furniture body. In this way, when the wall material is used for the curved portion, compared with the case where the wall material is used for the straight portion, a continuous beautiful curved surface using the smooth bending deformation of the wall material itself in the intermediate portion even at the minimum fastening portion. Can be formed.

In order for the wall material to maintain a good shape with a minimum fastening portion, the wall material has at least a pair of hinge portions, and these hinge portions are connected to the furniture body. The wall material is fixed to the furniture main body in correspondence with the predetermined corner portion, so that tension is applied to a portion of the wall material located between the corner portions. Is desirable. At this time, if the wall material forms a curved outer wall, it is preferable to provide a curved backup material on the furniture body and attach the wall material to the backup material.

As a concrete embodiment of such a wall material, the wall material has hinge portions near both side ends, and the hinge body is used to form a rectangular cross section of the furniture body. One in which both side ends of the wall material are densely wound around the support and fastened thereto can be cited. As a specific structure of the wall material, a material having a three-layer structure in which a cushion layer is interposed between a backing layer and a surface layer is exemplified.

[0010] As a specific configuration of the hinge portion, there can be cited one in which the hinge portion is a concave groove formed on the outer surface of the backing layer. As a specific method of forming the concave groove, there is a method of forming the concave groove by pressing a pressing blade against the outer surface of the backing layer while applying heat energy.
In order to make the above-mentioned wall material more effective, it is desirable to apply the wall material to a movable furniture body.

Since both side edges 4a and 4b are tightly wound and fixed, the columns 91 and 9 which are one of the frames of the chair body 1 and the memo table body 1 are provided.
By using 3, 23, and 25, a member for separately fixing the wall material is not required, and the number of components can be reduced, and the bending of the wall material 4 using the hinge 18 can be appropriately performed.

The wall material 4 comprises a backing layer 15 and a surface layer 16.
Since it has a three-layer structure in which the cushion layer 17 is interposed therebetween, each layer can be constituted by a combination of various materials. For example, as in the present embodiment, a material having a relatively high shape-retaining property is used for the backing layer 15, a material having an excellent cushioning effect is used for the cushion layer 17, and a material having an appearance meeting various needs is used for the surface layer 16. The degree of freedom of the configuration such as use is obtained.

Since the hinge portion 18 is formed by forming a concave groove on the outer surface of the backing layer 15, the hinge portion 18 can be integrally formed only by performing simple processing on the wall material. Since the hinge portion 18 is formed by pressing the pressing blade 19 against the outer surface of the backing layer 15 while applying heat energy, the processing can be completed instantaneously without impairing the effective material strength. it can.

Further, since the wall member 4 is used for a movable chair with a memo table, the above-mentioned effects are more effective. The specific configuration of each unit is not limited to the embodiment described above. For example, in this embodiment, a case where a chair is used as moving furniture has been described. However, a wagon or a desk having a rectangular shape in plan view may be used. In addition, furniture that is not fixed and that is used without moving means may be used. In addition, the configuration of each part can be variously modified without departing from the spirit of the present invention.

[0027]

The present invention is embodied in the form described above and has the following effects. That is, the furniture of the present invention includes a furniture body and a wall material provided on the furniture body, and the wall material is made of a synthetic resin material having a cushion layer, and the wall material Ri Na formed integrally with the hinge portion at positions corresponding to the corners of the furniture body in the corresponding said hinge portion to a predetermined angle section of the furniture body
Then, the wall material is wound around the corner in a bent state and
By attaching to the furniture body, tension is applied to the wall material.
That the furniture is placed on the furniture body
Features .

With such a configuration, even when the wall material comes into contact with the user or other furniture, no loud collision noise is generated, and since the wall material has a cushioning effect of absorbing the impact, it has another effect. Not only is it less likely to damage furniture and users, but it is also less prone to plastic deformation. Furthermore, there is no cold and unpleasant contact sensation unlike a metal plate, and the contact sensation is good, and the appearance of the furniture as a whole is warm without being inorganic. Moreover, if the material is made of a synthetic resin, a hinge for attaching the wall material to the furniture body can be formed integrally with the wall material. By providing such a hinge portion, the fastening portion can be formed. Can be folded to a position that is not visible from the outside to improve the appearance, and compared to the case where the wall material is fixed to the furniture body without bending, the wall material may be stretched or external force may act on the wall material In this case, too, no excessive force is applied to the fastening portion, and a simple fastening tool such as a one-touch clip can be used.

If the wall material forms a curved outer wall by fixing at least both ends thereof to the furniture main body, even if the wall material is used for a straight portion, even a minimum fastening portion is required. A continuous beautiful curved surface can be formed in the intermediate portion by utilizing the smooth bending deformation of the wall material itself. The wall material has at least a pair of hinges, and the hinges are fixed to the furniture main body in such a manner that the hinges correspond to predetermined corners of the furniture main body. If a setting is made so that tension can be applied to a portion located between the corners, a fixed shape can be satisfactorily held with the minimum fastening portion. In this case, when the wall material forms a curved outer wall, it is more effective to provide a curved backup material on the furniture body and attach the wall material to the backup material.

The wall member has hinge portions near both side ends, and the both end portions of the wall member are densely wound around a pillar having a rectangular cross section of the furniture body by using the hinge portions. If it is fastened, using a pillar that is one of the frameworks of the furniture main body eliminates the need for a separate member to fasten the wall material, reducing the number of parts and reducing the hinge part of the wall material. The used bending can also be appropriately performed.

If the wall material has a three-layer structure in which a cushion layer is interposed between a backing layer and a surface layer, each layer can be composed of a combination of various materials. The degree of freedom of the configuration is obtained such that a relatively high shape-retaining material is used for the backing layer, a cushioning layer having excellent cushioning effect is used, and a surface layer having an appearance that meets various needs is used.

If the hinge portion has a groove formed on the outer surface of the backing layer, the hinge portion can be integrally formed only by performing a simple processing on the wall material. If the concave groove is formed by pressing the pressing blade against the outer surface of the backing layer while applying heat energy, the processing can be completed instantaneously without impairing the effective material strength.

If the furniture main body is movable, the above-mentioned effects become more effective.
