Abstract
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.
Claims18
A button for clothing fabric comprising:
- a metallic dome;
- a metallic bell-shaped part having a hollow tubular portion and a flanged portion depending from an end of said tubular portion, said flanged portion of said bell-shaped part being coupled with said dome;
- a core contained in said hollow tubular portion of said bell-shaped part, said core having a disk-shaped portion and an axial stem connected to said disk-shaped portion at a first end of the stem, said stem having a square cross-section defining respective corners at least at a second free end thereof, the stem being further force-fitted inside said hollow tubular portion of said bell-shaped part which is complementarily shaped by plastic deformation at least at said corners of said stem for providing a coupling in which mutual rotation of said dome and said bell-shaped part is prevented and such that at least a portion of said second free end protrudes out of said hollow tubular portion, and said stem having a blind axial channel;
- a nail being engageable in said axial channel;
- first raised portions for engaging the fabric being provided on a front surface of said second end of said stem such that said first raised portions are positioned outside of said hollow tubular portion for engaging the fabric;
- and
- second raised portions protruding from a facing surface of a head of said nail, said first and second raised portions being mutually positioned for engaging said fabric such that in an engaged fixed configuration of the button said first and second raised portions are mutually axially offset and do not mutually engage.
A button for attachment to fabric comprising:
- a hollow tubular portion having a first end and a second end;
- an axial stem accommodated inside said hollow tubular portion and having a first end and a second free end portion protruding from said second end of said hollow tubular portion;
- wherein said hollow tubular portion and said axial stem form an axial central portion of the button and wherein the button further comprises:
- a button flange portion connected to said axial central portion and arranged adjacent said first ends of said hollow tubular portion and said axial stem;
- a head connectable to said axial central portion in a manner such that the fabric is arranged between the head and the second free end portion of the axial stem in an engaged fixed configuration of the button;
- a first raised protruding structure provided on said second free end portion of said axial stem such that said first raised protruding structure is positioned outside of said hollow tubular portion for engaging the fabric;
- and
- a second raised protruding structure provided on said head such that said first and second raised protruding structures are mutually axially offset and do not mutually engage but engage instead with opposite surfaces of the fabric in the engaged fixed configuration of the button to form a rippled configuration of the fabric.
