Fastener for mounting objects on plates

Abstract

The invention relates to a fastener intended for mounting objects on plates, comprising two mutually movable tongues ( 2, 4 ), which are pressable against opposite sides of a plate. The two tongues ( 2, 4 ) are included in separate parts ( 1, 3 ), a first one ( 1 ) of which includes two male-like, elastic resilient fingers ( 5, 5 ′) having first serrations ( 6 ), while the second part ( 3 ) comprises a seat ( 11 ), which is delimited by second serrations ( 12 ). The two fingers ( 5, 5 ′) are insertable in the seat ( 11 ) to a depth which is determined by the thickness of the plate, the fingers ( 5, 5 ′) as a consequence of the inherent elasticity thereof being kept resiliently pressed in the seat with the first serrations ( 6 ) in engagement with the second serrations ( 12 ) in order to lock the parts in relation to each other.

1 . Fastener for mounting objects on plates, including two mutually movable tongues ( 2 ,  4 ), a first one ( 2 ) of which is pressable against the bottom side of a plate and the second one ( 4 ) is pressable against the top side of the plate, characterized in that the two tongues ( 2 ,  4 ) are included in separate parts ( 1 ,  3 ), a first one ( 1 ) of which includes two male-like, elastic resilient fingers ( 5 ,  5 ′), of which at least one includes a first serration ( 6 ), while the second part ( 3 ) comprises a seat ( 11 ), which is delimited by at least one second serration ( 12 ), and that the two fingers ( 5 ,  5 ′) are insertable in the seat ( 11 ) to a depth which is determined by the thickness of the plate, the fingers as a consequence of the inherent elasticity thereof being kept resiliently pressed in the seat with a first serration ( 6 ) in engagement with a second serration ( 12 ) in order to lock the parts in relation to each other.  
     
     
         2 . Fastener according to  claim 1 , characterized in that the fingers ( 5 ,  5 ′) are formed with a first, outwardly facing serration ( 6 ) each, and that the seat ( 11 ) is delimited by two second serrations ( 12 ) turned towards each other.  
     
     
         3 . Fastener according to  claim 1  or  2 , characterized in that the individual finger ( 5 ) on one hand includes a web ( 8 ), and on the other hand a bead ( 9 ) on which the first serration ( 6 ) is formed, and that the seat ( 11 ) is delimited between two flanges ( 13 ), which together with a rear wall ( 14 ) in the second part ( 3 ) define a through gap ( 15 ) in which the web ( 8 ) of the first part ( 1 ) is insertable.  
     
     
         4 . Fastener according to  claim 3 , characterized in that the two fingers ( 5 ,  5 ′) at the top have recesses ( 10 ) for a tool by means of which the fingers may be approached each other against the action of the inherent elasticity of the fingers, more precisely with the purpose of releasing the locking engagement between the serrations ( 6 ,  12 ).  
     
     
         5 . Fastener according to any one of the preceding claims, characterized in that the second part ( 3 ) includes a cross-section-wise U-shaped bracket ( 14 ,  17 ,  18 ).
