Attachment Arrangement for Releasable Attachment of Pull-Out Guides on Drawers

Abstract

Disclosed is a fastening arrangement for detachably fixing the forward end of the sliding rail ( 16 ) of drawer draw-out guides to an associated drawer by means of a fastening mounting ( 10 ) which can be mounted on the drawer at the forward end of the sliding rail ( 16 ) facing the front cover, “forward” being in relation to the direction of extraction. Said fastening mounting comprises a housing ( 18 ) in which the free end of a spring-biased locking protrusion ( 24 ) that is movably guided within the housing is mounted so as to engage into an elongate locking receiving device ( 30 ) that is provided in the sliding rail while being retractable from said locking receiving device counter to the spring bias. The housing ( 18 ) of the fastening mounting ( 10 ) is disposed on the bottom face of the drawer bottom ( 12 ), directly next to the sliding rail ( 16 ). The locking protrusion ( 24 ) that engages into the locking receiving device in the facing wall of the sliding rail is provided with a bordering edge ( 28 ) in the area that protrudes from the housing ( 18 ) and points in the direction of extraction of the sliding rail. Said bordering edge ( 28 ) extends regularly, runs at an angle from the direction of extraction, and is urged into contact with the forward end of the locking receiving device in the appropriate locked position, “forward” once again being in relation to the direction of extraction.

       2 . An attachment arrangement according to  claim 1 , characterised in that the bordering edge ( 28 ) of the locking projecting pressing on the front end of the locking retainer ( 30 ) in the pull-out direction has an edge area, conically tapering or knife-like, sharpened toward the bordering edge. 
   
   
       3 . An attachment arrangement according to  claim 1 , characterised in that the bordering edge ( 28 ) of the locking projection running obliquely to the pull-out direction has a linear course. 
   
   
       4 . An attachment arrangement according to  claim 1 , characterised in that the bordering edge ( 28 ) of the locking projection running obliquely to the pull-out direction has a curved course. 
   
   
       5 . An attachment arrangement according to  claim 1 , characterised in that the locking projection ( 24 ) is held, guided in the housing ( 18 ) so as to move at a right angle to the pull-out direction of the slide rail. 
   
   
       6 . An attachment arrangement according to  claim 5 , characterised in that the locking projection ( 24 ) is tensioned in the locking position through a spring ( 26 ) supported at a housing wall. 
   
   
       7 . An attachment arrangement according to  claim 6 , characterised in that the locking projection ( 24 ) is made of plastic, and the spring ( 26 ) is a plastic spring integrally attached to the locking projection. 
   
   
       8 . An attachment arrangement according to  claim 6 , characterised in that the plastic spring is a spiral spring ( 26 ) that is integrally attached to the end of the locking projection ( 24 ) opposite to the end of the locking projection that protrudes from the housing ( 18 ) and that is supported on the housing wall opposite to that end of the locking projection. 
   
   
       9 . An attachment arrangement according to  claim 1 , characterised in that the housing ( 18 ) is made of plastic. 
   
   
       10 . An attachment arrangement according to  claim 1 , characterised in that the housing ( 18 ) has a low height and is provided with a surface that can contact the underside of the bottom of the associated drawer ( 12 ) and that means are provided for attaching the housing ( 18 ) to the bottom, and/or to the interior side of a front face of a drawer that overlaps the bottom in the downward direction beyond the underside of the bottom. 
   
   
       11 . An attachment arrangement according to  claim 10 , characterised in that in the area of the housing ( 18 ) facing the front face, recesses ( 20 ) are provided that are open at the underside, and in which additional holes ( 22   a;    22   b ) with reduced diameter are provided for passage of the shafts of attachment screws. 
   
   
       12 . An attachment arrangement according to  claim 11 , characterised in that holes ( 22   a ) are provided passing from the bottom of the recesses ( 20 ) to the underside ( 12 ) of the associated drawer, and/or holes ( 22   b ) are provided passing from the end wall, facing the front face, of the recesses ( 20 ) to the front face. 
   
   
       13 . An attachment arrangement according to  claim 1 , characterised in that, in addition to the locking projection ( 24 ), a height-adjustment slide is arranged at a right angle to the pull-out direction of the slide rail, parallel to the drawer bottom, between the drawer bottom ( 12 ) and the top side of the slide rail ( 16 ), which can be moved forward or back into the housing ( 18 ), where the height-adjustment slide tapers like a wedge in the direction toward its free front end pointing to the slide rail ( 16 ).
