Press-stud

Abstract

A press-stud comprises a male component which is selectively insertable by snap-fitting into a female component. The female component ( 10, 10′, 40 ) comprises a main body ( 11, 11′, 41 ) in which is housed a resilient annular member ( 13, 43 ), held within the main body by a cap ( 12, 12′, 42 ) fixed to the peripheral end of an annular appendage ( 23, 23′, 48 ) of the main body ( 11, 11′, 41 ). Different caps can be attached by modifying the configuration of the annular appendage ( 23, 23′, 48 ) only.

1 . A press-stud comprising a male component which is selectively insertable by snap-fitting into a female component, the female component comprising a main body in which is housed a resilient annular member, held within the main body by a cap fixed to the peripheral end of an annular appendage of the main body, different caps being attachable by modifying the configuration of the annular appendage only. 
     
     
         2 . A press-stud according to  claim 1 , wherein modifying the configuration of the annular appendage only comprises the inclination and/or curving of the appendage with respect to a plane orthogonal to the direction of buttoning. 
     
     
         3 . A press-stud according to  claim 1 , wherein the cap comprises an edge tightly turned around an end of the annular appendage. 
     
     
         4 . A press-stud according to  claim 1 , wherein the annular appendage also acts as a support for at least part of the cap. 
     
     
         5 . A press-stud according to  claim 1 , wherein the annular appendage also acts as a support for an outer flange of the resilient annular member. 
     
     
         6 . A press-stud according to  claim 1 , wherein the resilient annular member comprises a relatively massive outer annular portion, from which radial lips, having a cross section relatively thinner than that of the outer annular portion, extend inwards. 
     
     
         7 . A press-stud according to  claim 6 , wherein the radial lips have a hook-like configuration, with a tip substantially aligned with the upper face of the outer annular portion and separated therefrom by a circumferential groove. 
     
     
         8 . A press-stud according to  claim 6 , wherein the radial lips are separated from one another by deep longitudinal indentations which also extend into part of the outer annular portion. 
     
     
         9 . A press-stud as described and illustrated and for the specified purposes.
