Abstract

The utility model relates to a cylindrical back cushion sofa which comprises a seat surface, a handrail, and a back cushion; the back cushion has a structure that four cylinders bend slightly inside and are arranged in alignment besides one end of the handrail according to the principle of bigger lower part and smaller upper part, longer lower part and shorter upper part; the handrail is a single cylindrical structure which connects the seat surface and a second layer columnar back cushion, wherein, one end of the seat surface is thicker and the other end thereof is thinner; the thicker end is higher while the thinner end is lower. As the back cushion has the structure that four cylinders bend slightly inside and are arranged in alignment besides one end of the handrail according to the principle of bigger lower part and smaller upper part, longer lower part and shorter upper part, , the appearance of the cylindrical back cushion sofa looks like a sail boat, and the design of the cylindrical back cushion sofa is novel; sponges scrap can be fully used as filling, so utility model has strong resilience force, full shape and hard deformation, thereby conforming to the modeling of human lumbar spine, and leading the lumbar spine to be comfortable; as the handrail adopts the single cylindrical structure, the air flow of the sofa seat surface is not affected, and the sweat is not accumulated on the back after long-time sitting or lying.

Description

A kind of cylindrical back pad sofa

One, technical field

The utility model relates to a kind of sofa, especially a kind of cylindrical back pad sofa.

Two, background technology

Existing sofa, its back pad adopt the monoblock sponge to make, and the sponge area is bigger, add easily to produce leftover pieces man-hour, reduce the utilization rate of material; Because of the back pad sponge at each seat is a monomer, and the sponge area is bigger, causes the stressed degree varies of sponge during use easily, and the local compression degree varies of sponge easily reduces service life of sponge; The back pad moulding is too rigorous, lacks decorative effect, is not suitable for the use of leisure space; The back pad moulding does not meet the moulding of human body lumbar vertebrae, and the user is long-time to be used and easily produce the ache sense of discomfort such as sense of lumbar vertebrae; Sofa handrail adopts block, and the air that has a strong impact on the sofa seat surface flows, and easily causes the long-time seat long-pending sweat behind the back of lying, and influences the health of lumbar vertebrae.

Three, summary of the invention

The purpose of this utility model provides a kind of modern design, improves stock utilization, makes the comfortable sofa of lumbar vertebrae.

For achieving the above object, the utility model is achieved in that

It comprises seat surface, handrail, back pad, and described back pad is the past interior slightly warp architectures of four cylinders, presses and goes up little, the following long short handrail one end alignment arrangement of leaning on greatly; Described handrail is single cylindrical structural, connects seat surface and second layer column back pad.

Wherein seat surface is that the thick end of an end is thin, and a thick end height, a thin end are low.

Because the utility model back pad is that four cylinders are toward interior slightly warp architecture, go up little, the following long short handrail one end alignment arrangement of leaning on of down greatly, modern design, can make full use of the sponge leftover pieces, meet the moulding of human body lumbar vertebrae, can make lumbar vertebrae comfortable, handrail is single cylindrical structural, the air that does not influence the sofa seat surface flows, and is difficult for causing the long-time seat long-pending sweat of back of lying.

Four, description of drawings

Concrete structure of the present utility model is provided by the following drawings.

Fig. 1 is according to the cylindrical back pad sofa front view that the utility model proposes.

Fig. 2 is according to the cylindrical back pad sofa left view that the utility model proposes.

Sign in the accompanying drawing is represented respectively:

1. seat surface 2. handrails 3. back pads

Five, the specific embodiment

Can find out that from Fig. 1, Fig. 2 the utility model comprises seat surface 1, handrail 2, back pad 3, described back pad 3 is the past interior slightly warp architectures of four cylinders, presses and goes up little, the following long short handrail 2 one ends alignment arrangement of leaning on greatly; Described handrail 2 is single cylindrical structural, connects seat surface 1 and second layer column back pad 3.Wherein seat surface 1 is that the thick end of an end is thin, and a thick end height, a thin end are low.During manufacturing, be prototype, adopt four cylinders to process combination respectively, adopt the high resilience sponge, also can make full use of to add and produce leftover pieces man-hour, improve the utilization rate of material as filler with traditional sailing boat; It is thin that seat surface 1 is processed into the thick end of an end, and a thick end height, a thin end are low; Handrail 2 is processed into cylindrical, connects seat surface 1 and second layer column back pad 3, can improve the circulation of air effect of sofa seat surface 1.

Claims (2)

1. cylindrical back pad sofa, it comprises seat surface [1], handrail [2], back pad [3], it is characterized in that described back pad [3] be four cylinders toward interior slightly warp architectures, press big little, down long short by handrail [2] one ends alignment arrange; Described handrail [2] is single cylindrical structural, connects seat surface [1] and second layer column back pad [3].
