Spring mattress sponge side frame

Abstract

The invention relates to a spring mattress sponge side frame. The sponge side frame is in a square shape formed by sequentially connecting four sponge side plates of the same height end to end. The spring mattress sponge side frame is characterized in that every two adjacent sponge side plates are marked as the sponge side plate A and the sponge side plate B, wherein a protrusion stretching out in the long-axis direction is arranged on the end face of the sponge side plate A, and a gap capable of just containing the protrusion in an embedded mode is formed in the end face of the sponge side plate B; the protrusion is provided with at least one horizontal bonding surface making contact with the sponge side plate B, and the horizontal bonding surfaces of the sponge side plate A and the sponge side plate B is adhesively fixed through an adhesive. The protrusion is embedded into the horizontal bonding surface behind the sponge side plate B and coated with the adhesive for fixation. Due to the fact that the adhesive is located on the horizontal bonding surface, the contact surfaces coated with the adhesive is pressed more and more tightly due to external extrusion, the phenomenon that sponge restoration in the perpendicular direction is affected due to dislocation of the contact faces is avoided, and then normal springback of sponge is ensured.

Description

technical field [0001] The invention relates to a mattress, in particular to a sponge side frame of a spring mattress. Background technique [0002] With the improvement of people's living standards, people's requirements for quality of life are getting higher and higher. Spring mattresses have the advantages of good elasticity, good support, strong air permeability, and durability, and are widely loved by people. [0003] The spring-packed spring mattress is filled with spring layers in the sponge frame, and the spring layers are made of independent springs packed into non-woven bags and then connected and arranged, and then glued together. The spring layer is generally glued with a sponge layer. When in use, each spring pack can be stressed evenly and has a strong sense of comfort. [0004] There are certain defects in the current spring-encased spring mattresses: the sponge frame outside the spring layer is composed of four rectangular sponge sides or ends connected seq...

Problems solved by technology

[0004] There are certain defects in the current spring-encased spring mattresses: the sponge frame outside the spring layer is composed of four rectangular sponge sides or ends connected sequentially by adhesives. Or after the package is rolled and pressed, the connection on the vertical surface is bonded together due to a slight misalignment of the bonding surface and cannot be restored.
