Drawer guide rail assembly with releaseably secured bumpers

Abstract

A guide rail assembly is used with a drawer to guide the movement of the drawer into and out of an article of furniture. The assembly has a supporting rail attached to a supporting surface and a pull-out rail attached to the drawer. At least one carriage is positioned between the supporting rail and the pull-out rail, and the supporting rail and the pull-out rail have stops for limiting movement of the pull-out rail and the carriage with respect to the supporting rail. The impact associated with closing the drawer is absorbed and suppressed by releaseably secured bumpers which engage stops controlling each of the drawers during opening and closing. The bumpers may be changed to adjust to drawers or drawer contents of varying weights.

         6 . The assembly as claimed in  claim 5  wherein the third carriage is held between the stop of the intermediate rail and the stop of the pull out rail when the pull out rail is in forward position thereof.  
     
     
         7 . The assembly as claimed in  claim 5  wherein the second carriage has at least one bumper at the forward edge of one wall and at least one bumper at the rearward edge of one wall.  
     
     
         8 . The assembly as claimed in  claim 1  wherein the resilient bumper is rubber.  
     
     
         9 . The assembly as claimed in  claim 1  wherein the resilient bumper is soft plastic.  
     
     
         10 . The assembly as claimed in  claim 1  wherein each wall of the U-shaped member has two roller cages and a single roller in each roller cage.  
     
     
         11 . The assembly as claimed in  claim 7  wherein the resilient bumper is rubber.  
     
     
         12 . The assembly as claimed in  claim 7  wherein the resilient bumper is soft plastic.  
     
     
         13 . The assembly as claimed in  claim 8  wherein each wall of the U-shaped member has two roller cages and a single roller in each roller cage.
