Abstract

The utility model relates to a sponge spring cushion/sofa cushion. It includes upper and lower cladding and spring layer. The upper and lower cladding layers are sponge sheets and non-woven fabrics, and the middle spring layer is a sponge spring which is densely arranged. The sponge spring is a sponge cylinder, and through holes are uniformly distributed on the cylinder wall of the sponge cylinder, so that the cylinder wall is in a cut flower shape. The utility model adopts the sponge spring, has low manufacturing cost, long service life, soft and elastic feeling during use and comfortable use.

Description

Sponge spring cushion/sofa cushion

Technical Field

The utility model relates to an elastic cushion/sofa cushion, in particular to a sponge spring cushion/sofa cushion.

Background

As is known, spring cushions/sofa cushions are generally constructed of an upper and lower covering and an intermediate spring layer, which is typically constructed of uniformly distributed cylindrical wire springs. The steel wire spring is pressed when in use and makes a sound, the steel wire can rust to influence the service life of the steel wire spring, and the manufacturing cost of the steel wire spring is relatively high.

SUMMERY OF THE UTILITY MODEL

The utility model aims to provide a sponge spring cushion/sofa cushion to prior art not enough, manufacturing cost is lower, long service life uses and feels comfortable.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a sponge spring cushion/sofa cushion, includes upper covering, underclad and middle spring layer, its characterized in that: the upper cladding layer and the lower cladding layer are made of sponge sheets/non-woven fabrics, and the middle spring layer is made of sponge springs which are densely distributed and arranged.

The sponge spring is a sponge cylinder, and through holes are uniformly distributed on the cylinder wall of the sponge cylinder, so that the cylinder wall is in a cut flower shape.

The perforations are rhombic perforations, so that the cylinder wall forms a twill-grid-shaped cut flower shape.

The cut flower shape is provided with spacing widening strips.

The longitudinal length a of the rhombic perforation is 3-6 mm, and the interval between two longitudinally adjacent holes is 2-5 mm; the diameter d of the outer wall of the sponge cylinder is 4-10 cm, and the wall thickness b of the sponge cylinder is 1-3 cm; the longitudinal length h of the sponge cylinder is 5-10 cm.

The raw material of the sponge spring can be common sponge, slow-return memory sponge or high-resilience sponge according to the elastic requirements of the cushion/sofa cushion.

Compared with the prior art, the utility model has the following obvious substantive characteristics and technical progress;

the utility model discloses a sponge spring cushion/sofa cushion, middle spring layer wherein adopts sponge spring, and this sponge spring is a sponge section of thick bamboo, and the perforation that has even cloth on the section of thick bamboo wall makes the bobbin wall form the cut flower shape to very increase elasticity on the original elasticity basis of sponge. The supporting strength of the cut flower is enhanced by the spacing widening strips in the shape of the cut flower. The utility model provides a sponge spring can select different raw and other materials sponge and unidimensional section of thick bamboo size and cut flower shape and size to and choose for use unidimensional interval widening strip, thereby can constitute the sponge spring of unidimensional, different elasticity and different support hardness, with the design demand who satisfies the different elasticity and the hardness of cushion/sofa cushion. The sponge spring cushion/sofa cushion of the utility model has low manufacturing cost, long service life and comfortable use feeling.

Detailed Description

The preferred embodiments of the present invention are described in detail below with reference to the accompanying drawings:

the first embodiment is as follows:

referring to fig. 1-5, the sponge spring cushion/sofa cushion comprises an upper covering layer (1), a lower covering layer (3) and a middle elastic layer (2), wherein the upper covering layer (1) and the lower covering layer (3) are sponge sheets/non-woven fabrics; the middle spring layer (2) is a sponge spring (4) which is densely distributed and arranged.

Example two: the present embodiment is substantially the same as the first embodiment, and is characterized in that:

the sponge spring (4) is a sponge cylinder (5), and through holes (6) are uniformly distributed on the cylinder wall of the sponge cylinder (5) to enable the cylinder wall to form a cut flower shape (7). The perforation (6) is a diamond perforation, so that the cylinder wall forms a twill grid cut flower shape (7).

Example three: this embodiment is substantially the same as the second embodiment, except that:

the cut flower shape (7) is provided with spacing widening strips (8).

Example four: this embodiment is substantially the same as the second or third embodiment, and is characterized in that:

the longitudinal length a of each diamond-shaped perforation is 3-6 mm, the interval between every two adjacent longitudinal holes is 2-5 mm, the diameter d of the outer wall of the sponge cylinder (5) is 4-10 cm, and the wall thickness b of the sponge cylinder (5) is 1-3 cm; the longitudinal length h of the sponge cylinder (5) is 5-10 cm. The raw materials of the sponge spring (4) are common sponge, slow-return memory sponge or high-resilience sponge according to the elastic requirements of the cushion/sofa cushion.
