Drawer slide

Abstract

A drawer slide, having a plurality of slide members is provided. The slide members have a first elongate linear member and a second elongate linear member to slide within a channel defined by an interior surface of the first slide member. The first and second slide members each have a first end portion, a second end portion, and the interior surface defining the first and second channels, respectively. The first slide member is milled from a single piece of material and includes a wall located transversely across the second end portion. Preferably, the interior side edges of the first linear member and the exterior side edges of the immediate linear member further define a first pair of raceways within which a plurality of ball bearings and bearing spacers are alternately disposed to provide a smooth slide motion of the second slide member. The noise damper is a noise-absorbing cushion mounted to the interior surface of the second linear member at the second end portion thereof.

         9 . The drawer slide of  claim 1 , wherein the wall extends through an entire depth of the first channel. 
     
     
         10 . (canceled) 
     
     
         11 . The drawer slide of  claim 1 , wherein the first end portion of the first elongate linear member includes a first alignment notch. 
     
     
         12 . (canceled) 
     
     
         13 . The drawer slide of  claim 1 , further comprising a third linear member to slide within the second channel, the third elongate linear member having a first end portion and a second end portion. 
     
     
         14 . The drawer slide of  claim 13 , wherein exterior side edges of the third elongate linear member and interior side edges of the second elongate linear member defines a pair of second bearing raceways. 
     
     
         15 . The drawer slide of  claim 14 , further comprising a plurality of bearings and bearing spacers alternatively disposed within each of the second bearing raceways. 
     
     
         16 . The drawer slide of  claim 15 , wherein the third elongate linear member includes a pair of roll pins extending into the second channel at the second end portion thereof, and the second elongate linear member includes a pair of roll pins extending into the second channel from the first end portion thereof to confine the bearings and bearing spacers within the second bearing raceways. 
     
     
         17 . The drawer slide of  claim 15 , wherein the third elongate linear member has an interior surface defining a third channel. 
     
     
         18 . The drawer slide of  claim 17 , further comprising a fourth elongate linear member fitted within the third channel, the fourth elongate linear member having a first end portion aligned with the first end portion of the third elongate linear member and a second end portion positioned between the first and second end portions of the third elongate linear member.
