Mounting device of the guide rail of a drawer slide

Abstract

Mounting device ( 10 ) of the cabinet-internal end of the guide rail ( 14 ) of a roller drawer slide for drawers and the like disposed inside a cabinet body and spaced from the adjacent sidewall of the cabinet body on the rear wall of the cabinet body by a mounting fitting ( 12 ), which includes a mounting plate ( 16 ) attachable to the rear wall of the cabinet and a rail support ( 18 ) adjustably supported on the mounting plate ( 16 ), wherein the rail support ( 18 ) is formed by an adjustment plate ( 26 ) movably secured on the mounting plate ( 16 ), with a mounting profile receiving the cabinet-internal end of the guide rail protruding from the adjustment plate ( 26 ) towards the open cabinet side. The mounting profile is formed as a profile section ( 34 ) with an end that is open toward the front side of the body for insertion of the cabinet-internal end of the guide rail ( 14 ), wherein the profile section ( 34 ) surrounds the guide rail on the side facing the cabinet sidewall as well as on the top and bottom side and is open on the side facing the drawer slide. The partial sections of the profile section ( 34 ) which surround the top and bottom side of the guide rail ( 14 ) have an unobstructed spacing from each other that is a greater than the vertical height of the guide rail ( 14 ) as measured across the outside. The end section of the guide rail ( 14 ) received in the profile section ( 34 ) is deformed downwardly in at least a partial section by an amount corresponding to the difference between the unobstructed height between the sections of the profile section ( 34 ) surrounding the guide rail ( 14 ) and the outside height of the guide rail ( 14 ).

     characterized in 
 that the mounting profile is formed as a profile section ( 4 ), which is open on its end facing the front side of the body for insertion of the cabinet-internal end of the guide rail ( 14 ), surrounds the guide rail on the side facing the cabinet sidewall as well as on the top and bottom side, and is open on the side facing the drawer slide,  
 that the partial sections of the profile section ( 34 ) which surround the guide rail ( 14 ) on the top and bottom side have an unobstructed spacing from each other that is a greater than the vertical height of the guide rail ( 14 ) as measured across the outside, and  
 that the end section of the guide rail ( 14 ) received in the profile section ( 34 ) is deformed downwardly in at least a partial section by an amount corresponding to the difference between the unobstructed height between the sections of the profile section ( 34 ) surrounding the guide rail ( 14 ) and the outside height of the guide rail ( 14 ).  
 
   
   
       2 . Mounting device according to  claim 1 , wherein the guide rail ( 14 ) is formed by a metal profile with an elongated wall ( 40 ), which in a desired mounting position is essentially vertical, wherein strip-like sections ( 42   a ;  42   b ) forming tracks for at least one rotatably supported roller are bent over on the upper and lower edge of the wall, which sections ( 42   a ;  42   b ) are encompassed by the upper and lower partial section of the profile section of the rail support, characterized in that at least the lower strip-like section ( 42   b ) of the guide rail has in the insertion direction of the drawer a downward slope in the downwardly deformed region ( 42   d ).  
   
   
       3 . Mounting device according to  claim 2 , characterized in that channel-like grooves ( 44 ) are formed in the transition region of the profile section ( 34 ), which extend in the insertion direction between the vertical wall ( 36 ) and the strip-like sections ( 38   a ;  38   b ) surrounding the guide rail, and that tab-like projections ( 46   a ;  46   b ), which are provided in the downwardly deformed region and which protrude perpendicular from the guide rail ( 14 ) in the opposite direction, engage with the grooves ( 44 ).  
   
   
       4 . Mounting device according to  claim 3 , characterized in that the distance measured in the vertical direction over the free end faces of the tab-like projections ( 46   a ;  46   b ) is essentially equal to the distance measured between the bottom surfaces of the grooves ( 44 ).  
   
   
       5 . Mounting device according to  claim 3 , characterized in that the tab-like projections ( 46   a ;  46   b ) are offset from each other in the longitudinal direction of the guide rails.  
   
   
       6 . Mounting device according to  claim 5 , characterized in that the vertically upwardly projecting tab-like projection ( 46   a ) is offset towards the rear against the insertion direction relative to the vertically downwardly projecting tab-like projection ( 46   b ).  
   
   
       7 . Mounting device according to  claim 3 , characterized in that the tab-like projections ( 46   a ;  46   b ) protrude integrally from the essentially perpendicular wall ( 40 ) of the guide rail ( 14 ).  
   
   
       8 . Mounting device according to  claim 3 , characterized in that in the region of the projections engaging in the grooves ( 44 ), the width of the grooves ( 44 ) is essentially equal to the thickness of the material of the tab-like projections ( 46   a ;  46   b ) measured perpendicular to the insertion direction.
