Title:
FOLDABLE TENSION SPRING MATTRESS
Document Type and Number:
WIPO Patent Application WO/2019/019919
Kind Code:
A1
Abstract:
The invention relates to the field of mattresses, and particularly, discloses a foldable tension spring mattress. In the spring mattress, a vertical pressure is converted into a tension by means of a packaging carpet, the tension acts on the periphery of a spring net and is converted into a pull force acting on coil springs and coiling springs, and then the force is uniformly dispersed to each of the coil springs, so that the local overstressing of the coil springs and the coiling springs is avoided, and in turn the situation where the spring net and the coiling springs are arched and sunken is avoided. As a result, the mattress can always have good elasticity, and therefore, the comfort level of the spring mattress is increased. According to the solution, the plastic deformation of the coil springs can be reduced, so that the comfort level of the spring mattress is increased, and the elasticity and durability of the spring mattress are improved.
