Abstract
Abstract A side-mount drawer slide with a floating wheel permitting lateral movement of the drawer to compensate for skewness in the drawer and/or supporting cabinet. A drawer slide of the type having a track attached to the drawer and a corresponding track attached to the adjacent wall is provided with a pair of wheels, one secured at an end of each track. On one side the wheels have only minimal lateral play. On the other side the wheels have a substantial predetermined lateral play to compensate for lack of parallelism in the walls of the cabinet and/or drawer so as to avoid the need for shimming the tracks when the drawer and/or cabinet are not parallel.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
159 words
In a drawer slide for mounting a drawer in a cabinet having nominally parallel sidewalls, the drawer slide being of the type comprising a first, cabinet member adapted to be affixed to the cabinet, a second, drawer member adapted to be affixed to the drawer, and a wheel assembly, having a wheel mounted on an axle, mounted to a first of said cabinet and drawer members, said cabinet and drawer members and said wheel assembly being structured and arranged such that the other of said cabinet and drawer members rolls against said wheel as said drawer is moved in and out of said cabinet, the improvement wherein: said wheel assembly is structured and arranged to permit unbiased free travel of said wheel along said axle over a predetermined range of at least about 3/32 inch, whereby said wheel assembly provides for automatic lateral self-adjustment of said drawer slide to compensate for cabinets having sidewalls deviating significantly from parallel configuration.
Claim 2
Dependent Claim
159 words
In a drawer slide for mounting a drawer in a cabinet having nominally parallel sidewalls, the drawer slide being of the type comprising a first, cabinet member adapted to be affixed to the cabinet, a second, drawer member adapted to be affixed to the drawer, and a wheel assembly, having a wheel mounted on an axle, mounted to a first of said cabinet and drawer members, said cabinet and drawer members and said wheel assembly being structured and arranged such that the other of said cabinet and drawer members rolls against said wheel as said drawer is moved in and out of said cabinet, the improvement wherein: said wheel assembly is structured and arranged to permit unbiased free travel of said wheel along said axle over a predetermined range of at least about 3/32 inch, whereby said wheel assembly provides for automatic lateral self-adjustment of said drawer slide to compensate for cabinets having sidewalls deviating significantly from parallel configuration.
Claim 3
Dependent Claim
60 words
The invention of claim 1, wherein: said axle is formed with a stop at its distal end; and said wheel is mounted to slide laterally on said axle and is formed with a centrally disposed recessed region for receiving said stop and having a depth sufficient to provide said at least about 3/32 inch of lateral movement on said axle.
Claim 4
Dependent Claim
33 words
The invention of claim 1 wherein one of said cabinet and drawer members includes a lip formed for capturing said wheel and sized and configured to urge said wheel longitudinally along said axle.
Claim 5
Dependent Claim
223 words
In a drawer slide for mounting a drawer in a cabinet having nominally parallel sidewalls, the drawer slide being of the type comprising a first, cabinet member adapted to be affixed to the cabinet, a second, drawer member adapted to be affixed to the drawer, a first wheel assembly, having a wheel mounted on an axle, mounted to a first of said cabinet and drawer members generally at the forward portion thereof, a second wheel assembly, mounted on an axle, mounted to the other of said cabinet and drawer members generally in the rear portion thereof, and a lip formed for capturing one of said wheels, said cabinet and drawer members and said wheel assemblies being structured and arranged such that said members roll against said wheels as said drawer is moved in and out of said cabinet, the improvement wherein: each said wheel assembly is structured and arranged to permit unbiased free travel of the included wheel along the included axle over a predetermined range of at least about 3/32 inch, and said lip is sized and configured to urge said captured wheel longitudinally along its respective axle, whereby said wheel assemblies and lip provide for automatic lateral self-adjustment of said drawer slide at both the forward and rear portions thereof to compensate for cabinets having sidewalls deviating significantly from parallel configuration.
Claim 6
Dependent Claim
223 words
In a drawer slide for mounting a drawer in a cabinet having nominally parallel sidewalls, the drawer slide being of the type comprising a first, cabinet member adapted to be affixed to the cabinet, a second, drawer member adapted to be affixed to the drawer, a first wheel assembly, having a wheel mounted on an axle, mounted to a first of said cabinet and drawer members generally at the forward portion thereof, a second wheel assembly, mounted on an axle, mounted to the other of said cabinet and drawer members generally in the rear portion thereof, and a lip formed for capturing one of said wheels, said cabinet and drawer members and said wheel assemblies being structured and arranged such that said members roll against said wheels as said drawer is moved in and out of said cabinet, the improvement wherein: each said wheel assembly is structured and arranged to permit unbiased free travel of the included wheel along the included axle over a predetermined range of at least about 3/32 inch, and said lip is sized and configured to urge said captured wheel longitudinally along its respective axle, whereby said wheel assemblies and lip provide for automatic lateral self-adjustment of said drawer slide at both the forward and rear portions thereof to compensate for cabinets having sidewalls deviating significantly from parallel configuration.
Claim 7
Dependent Claim
70 words
The invention of claim 4, wherein: each said axle is formed with a stop at its distal end; and each said wheel is mounted to slide laterally on its respective axle and is formed with a centrally disposed recessed region for receiving the respective stop as the wheel moves laterally on its respective axle and having a depth sufficient to provide said at least about 3/32 inch of lateral movement.
