Description

The present invention relates to a sofa having a replaceable cushion member and outer surface.

A typical sofa is formed by fixing a spring material or cushion member to a wooden frame frame, covering the surface with a surface material, pulling the edge of the surface material to hold the surface material, and fixing it to the wooden frame frame with a nail or the like. ing. For this reason, replacement and replacement of parts when the outer material is soiled or the cushion member is damaged, etc., require craftsmen who have specialized skills by taking them to the factory, which requires high costs and a long repair period. .
Therefore, there are many sofas that are discarded without changing the tension or replacing members.

In addition, since it is not easy to replace the outer material, the entire sofa is often covered with a removable cover while leaving the outer material as it is. When covered with a cover in this way, it is possible to remove only the cover and wash it, or to change the interior to a wallpaper, curtain, etc., or a cover that suits the season.
However, simply covering a large cover different from the sofa shape will break the original design, which is an important value of the sofa, and changing the functions of the sofa itself such as air permeability and heat retention It was not possible to remove dirt and ticks that permeated the outer material and cushion members, and it was not possible to easily replace damaged parts.

Due to the emergence of hook-and-loop fasteners, sofas that are stopped with hook-and-loop fasteners without using hooks or nails when fixing the outer material to the frame are generally called “covering sofas” and distributed, and the outer surface is made of hook-and-loop fasteners. Because it is attached, it is said that there is an effect that can be easily removed, washed and replaced.
However, the manufacturing method that uses hook-and-loop fasteners has the main purpose of increasing the production efficiency of sofas, and it is not easy to attach and detach outer surfaces with complicated shapes such as armrests from large sofas. At the same time, changing the function of the sofa itself has not been realized by changing the outer surface alone.

Conventionally, a sofa is known in which an insertion tool is provided in a central recess surrounded by a backrest and an armrest, and a loop that passes through the insertion tool is provided with a fastener that detachably locks a jacket covering the entire sofa. (Patent Document 1).
In the above conventional sofa, the jacket covering part, the back covering part, and the arm rest covering part are continuously formed and locked with the fastener provided in the central recess, so the jacket is beautifully tensioned. It is difficult to stretch, and when a person sits on the sofa, the jacket is loose and prone to wrinkles.

No. 7-25083

  The problem to be solved by the present invention is that the outer material or cushion member can be easily replaced, and not only the damaged parts can be replaced, but also the overall design and function can be easily changed according to the season and interior. It is to provide a sofa that is beautifully stretched and hard to loosen.

  The sofa of the present invention has a frame, a cushion member, and an outer material, and the cushion member is attached to the frame, and the outer material is attached from above, the frame is composed of a seat frame and a backrest frame, It consists of a seat cushion member that can be attached to and detached from the frame and a back cushion member, and the outer surface is composed of a seat surface that covers the seat and a back surface that covers the back, and the front part of the seat is the cushion Covers the front of the member and is detachably attached to the seat frame or seat cushion member, and the upper part of the backrest part covering the upper surface of the backrest part is detachably attached to the backrest part frame and the rear part of the seat part And the lower part of the backrest part outer material is both pulled out backward from between the seat cushion member rear part and the back cushion member lower part, Please caution attached to the frame in a tension state.

A long horizontal bar in the width direction of the sofa is provided on the frame on the back side of the sofa, a hook is provided at the rear end of the seat surface and the lower end of the front of the backrest surface, and the hook is detachable from the horizontal bar. May lock.
Alternatively, a frame side belt is provided on the frame on the back side of the sofa, a front side belt is provided on the rear end of the seat surface and the lower end of the front surface of the backrest, and the front side belt and the frame side belt are attached and detached by a buckle. They can be connected freely.

The cushion member includes a cushioning material having a three-layer structure in which an intermediate layer made of insulator fiber is sandwiched between a surface layer made of a soft foam urethane having a large number of through holes and a back layer on which a large number of coil springs are arranged. Sometimes.
An armrest portion having an armrest portion frame may be provided, and an armrest portion outer surface may be detachably attached to the armrest portion frame.
The sofa shape may be changed by attaching a pad to the back surface of the outer material and changing the shape of the pad.

The cushion member is detachably attached to the frame, and the outer material is detachably attached to the frame or cushion member, so even if you are not a skilled craftsman, you can easily change the cushion member and outer material. In addition to the appearance of the sofa, functions such as breathability and heat retention can be easily changed according to the interior and interior, and even if the cushion member or outer material becomes dirty or damaged, it is easy to wash and replace parts Can do.
By changing to a surface with a change in shape by inserting a pad, it is possible to easily change the design of the entire sofa including the solid shape while leaving the wooden frame forming the design as it is,
Since the lower end of the front part of the back part of the seat part and the back part is pulled and attached to the back side of the sofa through the seat part and the back part, the seat part and the back part are tensioned so that no wrinkles come It can be stretched beautifully, and even if a person sits on the seat, the seat surface and backrest surface are difficult to loosen.
