Pull-out guide for drawers

Abstract

A pull-out guide for drawers consists of two 2 frame sides, U-shaped guide rails and Z-shaped pull-out rails movable therein, both the guide and pull-out rails being provided with a roller each, and the lower guide legs of the U-shaped guide rails having in their end areas run-in slopes adjoined by run-in stops each, and the front end areas of the upper pull-out rail legs, serving as rolling surfaces for the rollers, having a run-in slope each oriented in the same direction and preferably parallel to the run-in slope in the end area of the guide rail on the frame side. This improves the pull-in and staying closed behavior when drawers of little net weight and small load capacity are involved. Because the legs of both rail pairs of the pull-out guide run parallel, the front blind is approximately jointlessly flush with the frame.

I claim: 
     
       1. A pull-out guide .[.to be used in drawers and other similar objects.]. .Iadd.for supporting a drawer in a furniture frame .Iaddend.comprising: (a) a U-shaped guide rail .[.attached to a side wall of.]. .Iadd.mountable in a furniture frame for supporting .Iaddend.the drawer;   (b) a Z-shaped pull-out rail .[.located within.]. .Iadd.secured to the drawer and extending into .Iaddend.said U-shaped guide rail to move in a horizontal direction as the drawer is pulled out of and pushed into the furniture .Iadd.frame.Iaddend.;   (c) a front roller rotatably mounted in a front area of said guide rail .[.allowing the drawer to move in the horizontal direction.].;   (d) .Iadd.said guide rail having .Iaddend.an upper guide leg paired with a lower guide leg .[.fastened to the side wall of the drawer.]., said lower guide leg having a run-in slope in an .Iadd.end .Iaddend.area of said lower guide leg abutted by a run-in stop .[.and this arrangement is used in moving said drawer.].;   (e) a rear roller rotatably fastened to a rear end area of said Z-shaped pull-out rail .Iadd.for .Iaddend.moving in the horizontal direction and guided by a rolling contact along one surface of said lower guide leg and one surface of said upper guide leg;   (f) .Iadd.said pull-out rail having .Iaddend.an upper leg .[.paired with a lower leg of said Z-shaped pull-out rail, said upper leg.]. serving as a rolling surface .[.of.]. .Iadd.on .Iaddend.said front roller and having in a front end area a run-in slope parallel to said run-in slope of said .[.U-shaped.]. .Iadd.lower .Iaddend.guide .[.rail.]. .Iadd.leg.Iaddend., and said run-in slope of said upper leg .[.is.]. .Iadd.being .Iaddend.disposed a short distance from an end of said pull-out rail to enable said .[.front roller.]. .Iadd.drawer .Iaddend.to slide into .[.said drawer.]. .Iadd.the furniture frame by .[.passing.]. a bending edge .[.on.]. .Iadd.of the run-in slope of .Iaddend.said upper leg of said Z-shaped pull-out rail.[.,.]. .Iadd.passing over the front roller .Iaddend.while said rear roller is located along a horizontal area of said lower leg of said guide rail .Iadd.before the rear roller passes over a bending edge onto the run-in slope of the lower guide leg.Iaddend..   
     
     
       2. A pull-out guide according to claim 1, wherein .[.said bending edge on.]. said upper leg of said Z-shaped pull-out rail .[.is used.]. .Iadd.includes a bending edge at the upper end of the run-in slope thereof .Iaddend.to adjust .[.a.]. .Iadd.the .Iaddend.height of the drawer.
