DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a novel sofa with good sitting comfort and non-stickiness.

[0002]

2. Description of the Related Art Conventionally, a sofa is formed by using a wood or metal pipe to form a sofa frame, and a required elastic material is attached to the sofa frame to form a sofa body as a core. It has been formed by wrapping.

[0003]

However, the formation of a sofa frame made of wood or metal pipe and the formation of a sofa body by attaching an elastic material require a high degree of skill and a great deal of time and labor. There is a problem that the production is expensive because it hinders efficient production, and there is a problem that it is heavy and difficult to handle.

[0004] In addition, there is a problem that the seating surface is made to sit down due to the repetition of the seating by the user, and that settling occurs.

[0005]

According to the present invention, a sofa body having a horizontally long stool portion and a backrest portion is formed of urethane or the like whose elasticity is adjusted, and an upper surface is formed on the entire inner surface of the stool portion of the sofa body. An open concave portion is provided, a spring cushion and an elastic mat are overlapped in the concave portion to form a seating surface, and the sofa body is covered and covered with a surface material such as leather, cloth, or synthetic resin. This problem was solved.

[0006]

BEST MODE FOR CARRYING OUT THE INVENTION A combination of molding materials such as urethane and urethane chips of which elasticity has been adjusted is a thick part having a horizontally long stool 1 and a backrest 2 and elbow rests 3a and 3b on both sides. The sofa body 4 having a moderate elasticity is formed.

[0007] The seat 1 of the sofa body 4 has elbow rests 3a,
A concave portion 5 having an open upper surface is formed on the entire inner surface except for 3b,
A plurality of coil springs 6 arranged in parallel in the vertical direction in the form of a bed and a spring cushion 8 wrapped around the coil spring 6 with a net 7 are fitted and laid in the recesses 5, and urethane is placed on the spring cushion 8 with urethane. The elastic mat 9 to be formed is superimposed to form the seating surface 10. Reference numerals 11a and 11b denote flaw-proof surfaces which are laid on the upper and lower surfaces of the spring cushion 8, respectively.
And the elastic mat 9 is protected from being damaged. As the flaw-proof surface bodies 11a and 11b, use is made of palm fiber, synthetic resin fiber or the like which is strong against pressure and excellent in flexibility.

The sofa body 4 provided with the seating surface 10 is wrapped and covered with a surface material 12 such as leather which is separately manufactured. Reference numeral 13 denotes a cover sheet for protecting the bottom surface of the stool 1.

The sofa 14 thus formed does not require a frame such as wood or metal pipe, and can be formed by a simple process of covering the outer surface of the sofa body 4 with a covering material. In addition, since the seating surface 10 is formed by overlapping the spring cushion 8 and the elastic mat 9, the user touches the soft elastic mat 9 first when the user sits down, and then the user has a strong waist. Since the spring cushion 8 works, the seating comfort is good, and the presence of the spring cushion 8 makes it difficult for the user to sit down. Will not occur.

Although the drawings show a two-seat sofa, a single-seat chair can be formed in the same manner as a three-seat or four-seat sofa.

[0011]

According to the present invention, as described above, a sofa body whose elasticity is adjusted with an elastic material such as urethane is formed, and the sofa body is wrapped and covered with a surface material such as leather. Since the sofa can be formed in the process, there is an effect that the sofa can be efficiently produced.

The stool portion of the sofa body is recessed so that a spring cushion and an elastic mat are superimposed to form a stool surface. There is an effect that no sagging occurs.

Since the spring cushion is wrapped in the net and the upper and lower surfaces are covered with the flaw-proof surface body, it is possible to prevent the sofa body from being damaged due to the protrusion of the spring end.

Claims (1)

(57) [Claims] 1. A sofa body integrally having a horizontally long stool, an elbow rest on both sides of the stool and a backrest on the back is made of urethane or the like having adjusted elasticity. The body is provided with a concave part with an open top on the entire inner surface except for the elbow rest part of the stool, and a spring cushion formed by wrapping a number of coil springs arranged vertically in a net in the concave part is fitted and laid. An anti-scratch surface is laid on the upper and lower surfaces of the spring cushion, an elastic mat is superimposed on the anti-scratch surface to form a seating surface, and the sofa body is made of leather, cloth or synthetic resin. A sofa characterized by being covered and covered with materials.
