Abstract

The utility model discloses a sofa framework with an improved structure. The sofa framework comprises a framework body, a spring layer and a net layer. The spring layer comprises a plurality of S-shaped springs distributed on the same plane in the framework parallelly, two ends of each S-shaped spring are both connected with the framework, simultaneously the net layer is fixed above the spring layer, adjacent S-shaped springs are connected through a plurality of parallelly arranged bi-directional spring hooks, and the S-shaped springs adjacent to the framework and the framework are also connected through the plurality of parallelly arranged bi-directional spring hooks. Included angles larger than 0 degree and smaller than or equal to 90 degrees are arranged between the bi-directional spring hooks and the S-shaped springs. All the S-shaped springs are connected and fixed through a plurality of steel bars, and the steel bars are perpendicular to the S-shaped springs. The sofa framework with the improved structure is easy to assemble and maintain, firm in structure, good in elasticity and capable of improving use comfortableness effectively. A sofa cushion can not be deformed after being used for a long time, and service life is greatly prolonged.

Description

The Frame of sofa structure-improved

Technical field

The utility model relates to a kind of sofa, relates in particular to a kind of structure improved Frame of sofa that has.

Background technology

At present, the Frame of sofa of commonly seeing all is to adopt following structure, namely, the some S type springs that connect parallel distribution at wooden frame material, with each S type spring and the elastic cord that is about 3-5cm and wrong the connection, then on the layer of S type spring and elastic cord composition, follow closely again one deck net again, and at this online bonding sponge.Such skeleton elasticity is relatively poor, and is also insecure, and easy distortion of long duration, and can not provide comfortable experience for the user.

The utility model content

The purpose of this utility model is to propose a kind of structure improved Frame of sofa that has, and its sound construction has favorable elasticity, and is not yielding, durable in use, can provide comfortable experience for the user, thereby has overcome deficiency of the prior art.

For achieving the above object, the utility model has adopted following technical scheme:

A kind of Frame of sofa structure-improved, comprise framework, spring layer and lamina reticularis, this spring layer comprises the parallel plural S type spring on the same plane in the framework that is distributed in, and each S type both ends of the spring all is connected with framework, simultaneously, this lamina reticularis is fixed in this spring layer top, all is connected by plural bidirectional spring hook between the adjacent S type spring and between the S type spring of contiguous framework and the framework, have greater than 0 ° between described bidirectional spring hook and the S type spring, and be less than or equal to 90 ° angle; All S type springs are connected and fixed with some reinforcing bars, and described reinforcing bar is vertical with S type spring.

Preferably, the contact site of described reinforcing bar and S type spring is fixed reinforcing bar and S type spring with clip.

Further, the S type spring by framework is walked around at the two ends of reinforcing bar, and bending returns to form a latch closure, also fixes with clip between the reinforcing bar.

Preferably, described reinforcing bar outer surface paper using wrapping.

Preferably, parallel being distributed on the same plane of this plural number bidirectional spring hook.

Described S type both ends of the spring and bidirectional spring hook one end that is connected with framework all are fixedly connected with framework by the spring clip that is arranged on the framework.

Described lamina reticularis adopts ventilative knitmesh, also fixedly is bonded with spongy layer in the described ventilative knitmesh.

Preferably, the grid of described lamina reticularis is circular.

Compared with prior art, the utility model has the advantage of: Frame of sofa has been carried out improvement design, and substitute the structure of elastic cord in the past with the bidirectional spring hook, not only so that the easier assembling of Frame of sofa, and make more fastness of whole Frame of sofa, prolonged its service life, in addition because of the elasticity of bidirectional spring hook than flat degree of tightness with increasing larger elasticity, make the flexible increase of the people who is sitting on the sofa, increase its comfort level, and used reinforcing bar to fix S type spring, so that sofa cushion can not be out of shape because of long-term the seat yet.

The utility model also can be used for mattress, in the similar structures such as cushion.

Description of drawings

Fig. 1 is the structural representation of the utility model one preferred embodiment;

Fig. 2 is the fixedly partial enlarged drawing of S type spring of the utility model reinforcing bar.

Wherein, 1, framework, 2, S type spring, 3, the bidirectional spring hook, 4, spring clip, 5, parallel net, 6, strengthen structure, 7, reinforcing bar, 8, clip.

The specific embodiment

Below in conjunction with accompanying drawing and a preferred embodiment the technical solution of the utility model is further described.

Consulting Fig. 1 is a preferred embodiment of the present utility model, its Frame of sofa that relates to has in length and breadth spring agent structure, namely, S type spring 2 except horizontally-arranged, and between the horizontally-arranged spring, couple together with the S type spring 2 of bidirectional spring hook 3 with front and rear row, S type spring 2 nails were on flitch material (framework 1) before this, spring and flitch material are to pierce into spring clip 4 with spring, then be screwed on the sofa yoke with the word tapping, some reinforcing bars of all S type spring 2 usefulness 7 are connected and fixed, and described reinforcing bar 7 is vertical with S type spring 2.Adopt clip 8 with reinforcing bar 7 and S type spring 2 fixing next be that ventilative knitmesh (parallel net 5) is followed closely on sofa frame with the horse nail again, then be adhesive on the sofa frame with sponge.In addition, for improving the firmness of framework 1, also can arrange in the Qi Sijiao inboard and strengthen structure 6.

This Frame of sofa through improvement design not only is easier to I﹠ M, and structure is fastness more, and elasticity is good, Effective Raise the comfort level of using, and sofa cushion can not be out of shape because of long-term the seat yet, significantly prolong service life.This skeleton also can be used for mattress, in the similar structures such as cushion.

It is to be noted; the above person only is in order to explain the preferred embodiment of the utility model; be not that attempt is done any formal restriction to the utility model according to this; be with; all have in lower any modification or change of making relevant the utility model of identical utility model spirit, all must be included in the category of the utility model intention protection.
