Clip

Abstract

A clip comprises a bush ( 20 ) and a pin ( 10 ) to be inserted into the bush. The pin includes a flange ( 11 ), a shank ( 12 ) extending downward from the lower surface of the flange, and an enlarged portion ( 15 ) at the lower end of the shank. The bush includes a ring portion ( 21 ) having a step for receiving the flange therein, a holding portion ( 23 ) provided on the downside of the periphery of the ring portion, a pair of opposed legs ( 25 ) each provided on the downside of the ring and on the inside of the holding portion, the legs are inclining inwardly. The bush also includes a pair of retaining portions ( 27 ) each provided at the lower end of the corresponding leg. After the pin and the bush are assembled, the assembled pin and bush are inserted into respective mounting holes of plate members to be fastened. Then, when the pin is pushed into the bush, the legs and the retaining portions are adapted to be moved outward by the enlarged portion of the pin so as to allow the plate members to be fastened between the lower surface of the holding portion of the bush and the respective upper surfaces of the retaining portions. Three surfaces consisting of the lower surface of the enlarged portion of the pin and the two lower surfaces of the retaining portions of the bush are substantially coplanar to form a continuous flash surface thereacross.

1 . A clip for fastening a plurality of plate members, said clip comprising a bush and a pin to be inserted into said bush, wherein 
 said pin includes a flange, a shank extending downward from the lower surface of said flange, and an enlarged portion at the lower end of said shank,    said bush includes a ring portion having a step for receiving said flange therein, a holding portion provided on the downside of the periphery of said ring portion, a pair of opposed legs inclining inwardly and provided on the downside of said ring portion and on the inside of said holding portion, and a pair of retaining portions each provided at the lower end of the corresponding leg, wherein    in an assembled state after said pin and said bush are assembled by inserting said enlarged portion of said pin into said bush, said pair of legs of said bush are adapted to maintain inward inclining, and    in a pushed-in state after said pin is fully pushed into said bush, said legs and said retaining portions are adapted to be moved outward by said enlarged portion of said pin so as to allow said plate members to be fastened between the lower surface of said holding portion of said bush and the respective upper surfaces of said retaining portions, and to allow the lower surface of said enlarged portion of said pin to be substantially coplanar with the respective lower surfaces of said retaining portions of said bush.    
     
     
         2 . A clip as defined in  claim 1 , wherein in said pushed-in state, the lower surface of said enlarged portion and the respective lower surfaces of said retaining portions are adapted to form a continuous flat surface thereacross.  
     
     
         3 . A clip as defined in  claim 2 , wherein said continuous flat surface has an oval shape.  
     
     
         4 . A clip as defined in  claim 1 , wherein said pin and said bush are provided with engagement means for allowing said pin and said bush to be engaged with one another so as to be held in said respective assembled and pushed-in states.  
     
     
         5 . A clip as defined in  claim 1 , wherein each of said legs of said bush is provided with a rib.  
     
     
         6 . A clip as defined in  claim 1 , wherein said ring portion of said bush is provided with a detaching groove for detaching said pin from said bush in said pushed-in state.
