ES293801U - Perfected spring for mattresses (Machine-translation by Google Translate, not legally binding) - Google Patents

Abstract

Improved spring for mattresses, essentially characterized by being constituted from a wire element of adequate elasticity, whose turns progressively increase from their extreme zones towards their middle area, such turns being included in the imaginary surface of a barrel body, having been foreseen that said wired element or spring itself is assisted by a bag of breathable fabric, antiallergic and waterproof, of great strength, which frees each spring from the adjacent ones in the context of the mattress, said bag constituting a physically independent element, for each one of the springs, or forming part of a textile band, considerably elongated, which closes on itself determining a tubular housing for a longitudinal or transverse alignment of springs themselves, which are separated by vertical seam lines, established between each pair of mue lles and compartmentalizing the tubular housing, with the particularity that the different tubular housings for the springs themselves, which participate in the mattress, are also fixed by sewing lines, through the laterally prominent areas of the same, in correspondence with the repeatedly quoted springs themselves.
