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.
