摘要:
A button for clothing, comprising a metallic dome associated with an equally metallic bell-shaped part, which contains a core and is associable with the fabric of the item of clothing by means of a nail. The core is provided with a disk-shaped portion with which an axial stem is associated; the free end of the stem has a square cross-section and is force-fitted inside the bell-shaped part, which becomes complementarily shaped by plastic deformation at least at its corners, producing an association in which mutual rotation of the parts is prevented. The stem is provided with a blind axial channel for the engagement of the nail and the front surface of its end is provided with first raised portions adapted to engage the fabric and to cooperate with second raised portions that extend from the facing surface of the head of the nail.

It is foreseen a button formable for initial setting out, on the hollow bottom of a boasting face (1) of a thermoplastic seal with central separator part (2), with upward balanced curvature, for obstructing the opening (3) of the same bottom. Said seal comes out from said opening (3) with pressing notckes system (4) determining a surface radial pattern (5) on the same plane, insisting on cloth to protect it from driving effect in fabrication phase and to permit the button permanent junction, centrally forming the centring structure (6) to direct the nail penetration. Said seal is held on bottom from its superior bucket part (7) with radial holding on the initial wall part. On the upper part the toothed form (8) of the alloy core base (9) determines an overall constraint seat making by channel (10), with initial conversion hollow to act as guide for nail penetration, and by terminal (11), with spherical sector in introduction wider than said channel, to permit during the nail sharp hollow part (12) deformation the bloxking realization by its incorporation being impossible the interchange for unthreading. The button completion is attainable by cap (13) application.
摘要:
The male component (10) of a press-stud has a dome (11) that extends, so as to form an undercut region (14), from a first base (15) that is formed by blanking and plastic deformation from a metal plate. An intermediate tubular element (12), which is also formed by blanking and plastic deformation from a metal plate, is inserted axially in the dome, affecting part of its internal extension. The intermediate tubular element (12) extends from a second base (16) to be seamed to the first base (15) by folding the perimetric edge of the first base (15). A stem (13) protrudes from a third base (17) and has such a cross-section and length as to pass through the intermediate element (12), perforating the fabric (20) to which the male component (10) of the press-stud is fixed, and to deform against the dome (11), interposing a wider region between the dome (11) and the end of the intermediate element (12).
摘要:
A pivoted button including a head (10) with an axial tubular stem (14) ending with an annular edge (15) that is folded outward and is retained by the edge (16) of a hole (17) provided on a disk-shaped base (18) cooperating with a clawed ring (23) for fixing to the fabric (25). The fabric (25) is arranged between the disk-shaped base (18) and the clawed ring (23) and the claws (24) penetrate the fabric (25) and clinch themselves in a recess (22) of the base (18) by compression. The button is characterized in that the region (14a) of the tubular stem (14) that is retained by the edge (16) of the hole (17) of the base (18) is limited not only by the folded edge (15) but also by a portion (14b) of the stem (14) that is raised with respect to the rest.
