Abstract
Abstract A drawer has longitudinally extending tracks in its opposite sides, each of which is adapted to co-operate with a drawer runner mounted in a cabinet in which the drawer is supported in use, a roller carriage being engaged in each track and co-operable with the associated runner to support the drawer on the runner, the roller carriage being freely movable relative to the track and the runner, and each of the tracks incorporating means to stabilize the drawer against rocking or tilting movement about the roller carriage during opening and closing. One form of stabilizing means comprises a shelf raised from the base of the associated track and extending rearwardly from the forward end thereof to engage beneath the runner and prevent upward movement of the front of the drawer during initial opening and final closing movement.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
149 words
A drawer having longitudinally extending tracks in its opposite sides, each of which is adapted to co-operate with a drawer runner mounted in a cabinet in which the drawer is supported in use, a roller carriage engaged in each track and co-operable with the associated runner to support the drawer on the runner, the roller carriage being freely movable relative to the track and the runner, and each of said tracks incorporating a formation formed within the track in the form of a shelf raised from the base of the track and extending rearwardly from the forward end thereof, the shelf being adapted to engage beneath the associated runner and limit upward movement of the track and hence the drawer relative to the associated runner during initial opening and final closing movement of the drawer, whereby to stabilise the drawer against rocking or tilting movement during opening and closing.
Claim 2
Dependent Claim
149 words
A drawer having longitudinally extending tracks in its opposite sides, each of which is adapted to co-operate with a drawer runner mounted in a cabinet in which the drawer is supported in use, a roller carriage engaged in each track and co-operable with the associated runner to support the drawer on the runner, the roller carriage being freely movable relative to the track and the runner, and each of said tracks incorporating a formation formed within the track in the form of a shelf raised from the base of the track and extending rearwardly from the forward end thereof, the shelf being adapted to engage beneath the associated runner and limit upward movement of the track and hence the drawer relative to the associated runner during initial opening and final closing movement of the drawer, whereby to stabilise the drawer against rocking or tilting movement during opening and closing.
