Abstract
Abstract A drawer assembly comprising a drawer slidably supported on a pair of drawer runners each comprising an elongated member of angle section having a mounting flange by means of which the runner may be mounted at a suitable location in a drawer cabinet or like supporting structure, and a drawer-engaging flange projecting at right angles to the mounting flange and adapted to extend into a runner recess formed in the drawer side, and means for taking up lateral clearance between the drawer and the drawer runners.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
141 words
A drawer assembly comprising a drawer having opposed side walls, a runner recess in each side wall, each runner recess being provided with opposed longitudinally-extending lips projecting across the mouth thereof, a pair of drawer runners each having a bearing member at its forward end for engagement in the associated runner recess and a horizontal flange slidably engageable with a guide and bearing member at the rear end of the drawer to support same during sliding movement of the drawer and a component mounted on said horizontal flange so as to extend into the runner recess in the drawer, the component incorporating at least one resilient projection adapted to act against the inner face of at least one of said longitudinal lips to apply lateral pressure to the drawer and hence take up lateral clearance between the drawer and the runner.
Claim 2
Dependent Claim
141 words
A drawer assembly comprising a drawer having opposed side walls, a runner recess in each side wall, each runner recess being provided with opposed longitudinally-extending lips projecting across the mouth thereof, a pair of drawer runners each having a bearing member at its forward end for engagement in the associated runner recess and a horizontal flange slidably engageable with a guide and bearing member at the rear end of the drawer to support same during sliding movement of the drawer and a component mounted on said horizontal flange so as to extend into the runner recess in the drawer, the component incorporating at least one resilient projection adapted to act against the inner face of at least one of said longitudinal lips to apply lateral pressure to the drawer and hence take up lateral clearance between the drawer and the runner.
Claim 3
Dependent Claim
37 words
