Press stud

Abstract

A press stud ( 10 ) comprises a male component ( 12 ) which can engage selectively by a snapping action in a female component ( 14 ) which comprises a resilient ring ( 15 ) which, in a closed condition of the press stud, keeps the male component ( 12 ) in connection with the female component ( 14 ). The female component ( 14 ) comprises a base structure ( 24 ) with a housing seat ( 30 ) for the resilient ring ( 15 ). A cover cap ( 34 ) is fixed to the base structure ( 24 ) so as to cover it at least partially and close off, at least partially, the housing seat ( 30 ) for the resilient ring ( 15 ).

1 . A press stud comprising a male component ( 12 ) which can engage selectively by a snapping action in a female component ( 14 ), wherein the female component comprises a resiliently deformable member ( 15 ,  16 ) which, in a closed condition of the press stud, retains the male component ( 12 ) in connection with the female component ( 14 ), characterized in that the female component ( 14 ) comprises a base structure ( 24 ) with a housing seat ( 30 ) for the resiliently deformable member ( 15 ,  16 ), cover cap means ( 34 ) being fixed to the base structure ( 24 ) to cover it at least partially and close off, at least partially, the housing seat ( 30 ) for the resiliently deformable member ( 15 ,  16 ). 
     
     
         2 . A press stud according to  claim 1 , characterized in that the female component ( 14 ) of the press stud is composed solely of the base structure ( 24 ), the resiliently deformable member ( 15 ,  16 ), and the cap means ( 34 ) fixed to the base structure ( 24 ) by bending a peripheral edge ( 44 ) of the cap means ( 34 ) around a portion of the base structure ( 24 ), the resiliently deformable member ( 15 ,  16 ) being housed in the housing ( 30 ) formed by the base structure ( 24 ) and at least partially closed by a portion of the cap means ( 34 ). 
     
     
         3 . A press stud according to  claim 1 , characterized in that the housing seat ( 30 ) is substantially cylindrical and is partially closed by an annular retaining edge ( 32 ) of the base structure ( 24 ). 
     
     
         4 . A press stud according to  claim 3 , characterized in that the housing seat ( 30 ) and the annular retaining edge ( 32 ) are made in one piece from the same bent sheet or plate. 
     
     
         5 . A press stud according to any  claim 1 , characterized in that the cap means ( 34 ) comprise an annular front face ( 36 ) which is substantially flat with a central hole ( 38 ), at least part of the annular front face ( 36 ) forming a stop element for the resiliently deformable member ( 15 ,  16 ). 
     
     
         6 . A press stud according to  claim 5 , characterized in that a rear surface ( 37 ) of the annular front face ( 36 ) of the cap means ( 34 ) bears against at least two support portions ( 48 ,  50 ) of the base structure ( 22 ). 
     
     
         7 . A press stud according to  claim 6 , characterized in that said at least two support portions ( 48 ,  50 ) are located on the same plane orthogonal to an axial direction (Z-Z) along which the male component ( 12 ) is introduced into the female component ( 14 ) and extracted therefrom. 
     
     
         8 . A press stud according to  claim 7 , characterized in that said at least two support portions ( 48 ,  50 ) are spaced apart radially with respect to said axial direction (Z-Z). 
     
     
         9 . A press stud according to  claim 8 , characterized in that said at least two support portions ( 48 ,  50 ) comprise a first, radially outer, support area ( 48 ), composed of the outer surface of the wall of the peripheral circumferential groove ( 28 ), and a second, radially inner, support area ( 50 ), formed by a front edge of the housing ( 30 ).
