Abstract

A stacked junction-type bagged spring for manufacturing spring mattresses comprises coil springs (1) and cloth (2), an upper row of cloth bags (3) in an upper layer and a lower row of cloth bags (4) in a lower layer being formed by the cloth (2), and the coil springs (1) being separately accommodated in the upper row of cloth bags (3) and the lower row of cloth bags (4). A composite bagged spring mattress with different softness on two sides can be realized by combining the stacked junction-type bagged springs into a mattress, providing greater comfort for sleeping or sitting. In addition, the structure is simple and reasonable, soft springs and hard springs are well linked and fixed, displacement cannot occur, and the strength is high. Moreover, the two layers of the mattress do not require any adhesion process, so that glue is saved, the costs are reduced, and the spring mattress is more durable and environmentally-friendly.

Description

Superimposed jointed pocket spring for making spring pad

Technical field

The present invention relates to a pocket spring, and more particularly to a superposed engagement pocket spring for making a spring pad.

Background technique

In order to increase the comfort of sleeping or sitting, the process of producing mattresses and sofa cushions in the past is to superimpose two independent soft spring pockets of different hardnesses to achieve different hardness and hardness on the front and back sides; or The softness and comfort of the top soft bottom layer is achieved, so that the user feels like a sponge when sleeping or sitting, and has sufficient support when jumping or pressing. However, there are two implementations of two different soft-packed pocket spring pads: one is stacked directly without connection, but this method will be phased out because the two pocket spring pads are not connected easily. Produce cushion displacement and deformation. The other is by sticking together with glue (see Figure 11). This method requires a lot of glue to be wasted and increases the cost. Moreover, it is also difficult to make the adhesion process. The glue also has a taste and is not environmentally friendly.

Summary of the invention

The object of the present invention is to provide a superimposed jointed pocket spring for making a spring pad with a simple and reasonable structure, a good connection and fixing between the soft and hard springs, and a cost saving, environmentally friendly and durable.

The object of the present invention can be attained by the following measures: a superposed jointed pocket spring for making a spring pad, comprising a coil spring, a cloth, characterized in that the cloth forms an upper row and a lower row of upper and lower layers The cloth bag and the coil spring are respectively installed in the upper row bag and the lower row bag.

The object of the present invention can also be achieved by the following measures: forming a top row and a bottom row of upper and lower layers with a piece of cloth. Two pieces of cloth are used to form the upper and lower cloth bags of the upper and lower layers. The upper and lower rows of the upper and lower layers are separated by a cloth joint. Each of the adjacent upper rows of bags is separated from each other by a cloth joint point, and each of the adjacent lower row of bags is also separated from each other by a cloth joint point to form two separate upper and lower pocket springs. The coil springs located in the upper row and the lower row of bags are formed by springs having different hardnesses. The cloth forms an upper row, a middle row and a lower row of upper, middle and lower layers, and the spiral springs are respectively arranged in the upper row, the middle row and the lower row.

The present invention has the following advantages over the prior art:

1. Combine the superimposed jointed pocket springs into a pad to realize a bagged spring composite pad with different softness on both sides to increase the comfort of sleeping or sitting. Moreover, the structure is simple and reasonable, and the soft and hard springs have good connection and fixation, no displacement, and high strength.

2, no glue process is needed, which saves glue, reduces cost, and is more durable and environmentally friendly.

detailed description

The invention will be further described in detail below with reference to the accompanying drawings (embodiments):

1 to 8, the present invention includes a cloth 2 and a coil spring 1. The upper row bag 3 and the lower row bag 4 of the upper and lower layers can be formed by using one or two pieces of the cloth 2; the coil springs 1 are respectively installed in the upper row bag 3 and the lower row bag 4. The upper and lower rows of the upper and lower panels 4 are separated by a cloth joint 5 . Each of the adjacent upper rows of bags 3 is separated from each other by a cloth joint point 9; each adjacent lower row of bags 4 is also separated from each other by a cloth joint point 10 to form upper and lower two separate pocket springs. The plurality of rows of the upper row of bags 3 and the lower row of bags 4 are bonded to each other by bonding points 11 to form a pad body. The coil springs 1 located in the upper row of bags 3 and the lower row of bags 4 are formed by springs having different hardnesses.

Referring to Figures 9 and 10, one or two pieces of cloth 2 may be used to form upper, middle and lower three layers of upper row bag 6, middle row bag 7 and lower row bag 8. The coil springs 1 are housed in the upper row of bags 6, the middle row of bags 7, and the lower row of bags 8, respectively. This structure is equivalent to a combination of three mats.
