Abstract
Box spring with plastic band support for mattress consisting of a frame (1) and a set of bands (2) made of extruded plastic positioned one by one so as to enclose the frame (1), tightened mechanically under a specific tension and joined at their ends by heat sealing, the majority of the bands being arranged transversely on the frame (1) but with some bands longitudinally arranged and interlaced with the former.
Claims3
A high-resistance box spring for supporting a mattress, said box spring comprising:
- a frame made of tubes, said tubes arranged to form said frame such that said tubes constitute a perimeter for an area on which the mattress would be supported;
- and
- a set of separate first plastic bands, each of said first plastic bands being made of a material that is slightly flexible but highly resistant to deformation, each of said first plastic bands being positioned around said tubes in an annular fashion and tightened to a tension of 15 to 18 kilograms so that ends of each of said first plastic bands overlap and the overlapped ends are heat sealed, and each of said first plastic bands is positioned on said frame so that said set of separate first plastic bands completely covers said area for supporting the mattress so as to form a continuous closed surface.
