Abstract

PROBLEM TO BE SOLVED: To produce a sofa with smaller number of component parts, efficiently, at a low cost, sturdily, and light in weight, by forming the framework through folding and welding of metal pipes. SOLUTION: The side end members 3 of the sofa framework having a seat bottom part 1 and seat back part 2 are formed from metal pipes. Between these side end members 3, metal pipes 4-7 in the form of straight pipe are parallel installed as stretching by welding in the positions between oversurface front parts of the seat bottom part 1, between its oversurface rear parts, and between the upper parts of the seat back part 2. On the seat back side of the seat bottom 1, metal plates 8 as shape holder are inserted and fastened, and a metal pipe 9 is installed as stretching by welding between the bottoms of this metal plate 8, and a number of thin bands of metal 10 are welded between the metal pipes 4 and 5 and the ones 5 and 6 so that the intended sofa framework 11 is built.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sofa. More specifically, the present invention relates to a sofa in which a framework of a sofa can be quickly and lightly and robustly assembled.

[0002]

2. Description of the Related Art Conventionally, a sofa is formed by using wood to form a sofa frame, pasting a required elastic material to the sofa frame, and wrapping it with a covering material such as cloth leather. .

[0003]

However, the formation of a sofa frame made of wood requires a high degree of skill in processing, assembling and assembling many fine pillars and plates, and also requires a great deal of labor and time. However, there was a problem that it became expensive.

[0004]

SUMMARY OF THE INVENTION The object of the present invention is to solve the problem by forming a sofa frame with a reduced number of parts by bending and welding a metal pipe.

[0005]

BRIEF DESCRIPTION OF THE DRAWINGS FIG.

The side end members 3 and 3 of the sofa frame having the stool 1 and the backrest 2 are formed by metal pipes.

[0007] Between the side end members 3, 3 of the sofa frame, straight pipe-shaped metal pipes 4, 5, 6, between the upper front portion and the upper rear portion of the seating portion 1 and between the upper portions of the backrest portion 2. 7 are welded in parallel, and metal plates 8, 8 for shape retention are sandwiched and attached to the backrest side of the stool 1. A metal pipe 9 is welded between the lower ends of the metal plates 8, 8. A large number of metal strips 10 are welded between the metal pipes 4, 5 and 5, 6 to form the sofa frame 11. Reference numeral 12 denotes a reinforcing plate welded and mounted between metal pipes 5 and 9.

[0008] The entire sofa frame 11 is covered with a sheet 13, and a cover member 14 made of a resilient urethane material is mounted on the stool 1, and elbow supports 15, 15 protruding on both sides are provided. Formed, and a number of coil springs 17
The spring cushions 17, 17 formed by wrapping the combination of a in the net 17b are mounted as elastic mats, and the cushions are slightly hardened on the spring cushions 17, 17 with palm fiber or the like. A material 18 is placed on the backing portion 2, and an inner covering member 19 made of urethane is attached to the backing portion 2. These outer surfaces are tension-wrapped with a covering material 20 such as leather or cloth, and the lower end thereof is covered with a sofa. A couch 23 is fixed to a wooden frame 21 attached to the lower end of the frame by screws or rivets with a stapler-like nail 22.

[0009]

According to the present invention, since the frame of the sofa is formed by bending and welding a metal pipe, the number of members can be reduced, and the sofa can be formed efficiently, inexpensively, and ruggedly and lightly. Is generated.

[0010] Since a metal plate for shape retention is sandwiched and attached to the backrest side of the stool of the metal pipe on both sides of the sofa frame,
The sofa frame has the effect of not crushing and deforming even under load.

[0011] Since the wooden frame was attached to the bottom of the sofa frame,
Regardless of whether the skeleton is made of metal, an effect is obtained in that the surface material can be nailed and fixed as before.
