Abstract
Abstract A drawer of the sort used in cabinets, desks, files and the like is supported for sliding movement by a single self-aligning center rail. The rail is mounted to the cabinet frame preferably above the drawer, extending from front to back. It is supported at its forward end by a bracket in fixed position and at the rear end by a cup-shaped receptacle allowing limited lateral movement of the rail end. A bifurcated drawer guide is attached at its lower end to the back wall of the drawer and at its upper end slidably engages the rail. The rail is tubular for the major portion thereof while the forward end is flattened to provide a partial stop action for the drawer and also provide means for the drawer to be fully removed. Low friction guide plates are mounted about the drawer opening for quiet, easy movement thereof.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
148 words
A system for mounting a drawer to a cabinet or the like, comprising a. an elongated rail substantially coextensive with the length of said drawer and mountable to said cabinet in a horizontal plane between the front and back walls of said cabinet parallel to the path of travel of said drawer, b. said rail being cylindrical over a substantial portion thereof and being formed with a vertically and longitudinally flattened portion at the forward end thereof, and, c. a unitary guide fixed to the back wall of said drawer and slidably engaging said rail, d. said guide being formed with a pair of spaced legs with inwardly extending end portions defining a restricted opening therebetween less than the diameter of said cylindrical portion and greater than the thickness of said flattened portion to allow separation of said guide and drawer from said rail at said flattened portion.
Claim 2
Independent Claim
148 words
A system for mounting a drawer to a cabinet or the like, comprising a. an elongated rail substantially coextensive with the length of said drawer and mountable to said cabinet in a horizontal plane between the front and back walls of said cabinet parallel to the path of travel of said drawer, b. said rail being cylindrical over a substantial portion thereof and being formed with a vertically and longitudinally flattened portion at the forward end thereof, and, c. a unitary guide fixed to the back wall of said drawer and slidably engaging said rail, d. said guide being formed with a pair of spaced legs with inwardly extending end portions defining a restricted opening therebetween less than the diameter of said cylindrical portion and greater than the thickness of said flattened portion to allow separation of said guide and drawer from said rail at said flattened portion.
Claim 3
Dependent Claim
35 words
A system according to claim 1 wherein said rail is formed with a tapered shouler between said cylindrical portion and said flattened portion to provide a yieldable stop for said guide moving against said shoulder.
Claim 4
Dependent Claim
28 words
A system according to claim 1 including front and rear brackets mountable to the front and rear walls of said cabinet and supporting opposite ends of said rail.
Claim 5
Dependent Claim
31 words
A system according to claim 3 wherein said rear bracket is formed with a relatively wide socket to receive the rear end of said rail and allow limited lateral movement thereof.
Claim 6
Dependent Claim
25 words
A system according to claim 1 including low friction corner glides mountable to the front of said cabinet at the corners of the drawer opening.
Claim 7
Dependent Claim
29 words
A system according to claim 1 wherein said guide is of a low friction molded plastic material the legs of which are adapted to yield slightly under applied pressure.
Claim 8
Dependent Claim
59 words
A system according to claim 5 wherein each of said corner glides is formed with an L-shaped flat plate adapted to be mounted to the vertical inner face of the front cabinet wall and a tapered lip formed perpendicularly to the inner edge of each leg of the plate to bear against the corner edges of the drawer opening.
Claim 9
Dependent Claim
41 words
A system according to claim 1 wherein said guide is formed with integral arcuate bosses on the inner opposing sides of said legs and at opposite ends thereof to slidably engage the cylindrical portion of said rail at different angular positions.
Claim 10
Dependent Claim
28 words
A system according to claim 8 wherein said guide is formed with an integral transverse shoulder adapted to engage the edge of the back wall of said drawer.
Claim 11
Dependent Claim
61 words
A system according to claim 3 wherein said front bracket is formed with a flat flange adapted to be mounted against the inner face of the cabinet front wall, a lip along an edge of said flange to engage the cabinet edge defining the drawer opening and an inwardly projecting socket dimensioned to snugly receive the flattened end of said rail.
