Abstract
The magnetic button, comprises a male element and a female element which cooperate magnetically with one another, and fixing elements for rearwardly fixing the male and female elements to flaps of fabric. The male element comprises a disk-like body in material sensitive to magnetic attraction and the female element comprises a disk-like body and a magnetic element for attracting the male element. The male element has, on its rear side, a recess tapering towards a hole for the insertion of a tubular end of a fixing element which has, on the opposite side to the tubular end, a collar adapted to retain a flap of fabric, or of other material, arranged on the rear side of the male element. On the bottom of said recess, at the hole, there is a substantially conical protrusion which penetrates into the tubular end pushed into the recess, through the hole, to open out and upturn the tubular end along the walls of the recess to rigidly associate the fixing element and the male element to one another.
