Abstract
An improved drawer slide having a deformable brake to hold the slide in any desired degree of extension. The slide is of the type which has an outer slide member with two inwardly-facing ball-bearing supporting grooves, an inner slide member with two outwardly-facing ball-bearing supporting grooves, a brake block is held on the outer slide member and is deformed so that it contacts the inner slide member when it is desired to lock the slide in position.
Claims11
An improved drawer slide of the type having an outer slide member having a longitudinal axis and a pair of inwardly-facing, ball-bearing supporting grooves, an inner slide member positioned within said outer slide member, said inner slide member having a pair of outwardly-facing, ball-bearing supporting grooves, a plurality of ball bearings held between said pair of grooves on said outer slide member and said pair of grooves on said inner slide member, said ball bearings being positioned by a ball retainer, wherein the improvement comprises:
- a deformable brake block held on said outer slide member and shaped so that said inner slide member may pass freely over said block when said brake block is not deformed, said brake block having an opening therein;
- a movable cam member held by said outer slide member and positioned within said opening in said brake block, said cam member being shaped so that it does not deform said brake block sufficiently to contact said inner slide member when it is in a first position and so that it deforms said deformable brake block so that it does contact said inner slide member when it is in a second position;
- and
- means to move said cam member between said first and second position.
An improved drawer slide of the type having an outer slide member having a longitudinal axis and a pair of inwardly-facing ball-bearing supporting grooves, an inner slide member positioned within said outer slide member, said inner slide member having a pair of outwardly-facing ball-bearing supporting grooves, a plurality of ball-bearings held between said pair of grooves on said outer slide member and said pair of grooves on said inner slide member, said ball-bearings being positioned by a ball retainer, wherein the improvement comprises:
- a deformable brake block, said brake block being held on said outer slide member and oriented so that said inner slide member may pass freely over said block, said brake block having means for deforming the block associated therewith;
- and
- actuating means affixed to said outer slide member and positioned so that it can be operated from the exterior of said outer slide member, said means for deforming the block causing said block to move from a first shape in which shape it does not deform said brake block sufficiently to contact said inner slide member and to move to a second shape so that said brake block contacts said inner slide member.
