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.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
208 words
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.
Claim 2
Dependent Claim
208 words
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.
Claim 3
Dependent Claim
28 words
The improved drawer slide of claim 1 wherein said brake member is supported at the ends thereof which lie along the longitudinal axis of said outer slide member.
Claim 4
Dependent Claim
17 words
Ihe improved drawer slide of claim 1 wherein said brake member is fabricated from a urethane elastomer.
Claim 5
Dependent Claim
16 words
The improved drawer slide of claim 1 wherein said brake member is generally rectangular in shape.
Claim 6
Dependent Claim
23 words
The improved drawer slide of claim 1 wherein said opening in said brake block is located in the center of the brake block.
Claim 7
Dependent Claim
27 words
The improved drawer slide of claim 1 wherein said means to move said cam member comprises a cam handle affixed to said cam member through a shaft.
Claim 8
Dependent Claim

The improved drawer slide of claim 1 wherein said brake block has a generally oval opening therein and said cam is about the same size and shape as said opening.
Claim 9
Dependent Claim
59 words
The improved drawer slide of claim 1 wherein said brake block is generally rectangular in shape and is held at the ends thereof which lie along the longitudinal axis of said outer slide member and said brake block has a generally rectangular opening therein and said cam member is generally about the same size and shape as said opening.
Claim 10
Dependent Claim
22 words
The improved drawer slide of claim 1 wherein said brake block is located near the exterior end of said outer slide member.
Claim 11
Dependent Claim
196 words
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.
Claim 12
Dependent Claim
196 words
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.
Claim 13
Dependent Claim
15 words
The improved drawer slide of claim 10 wherein said means for deforming comprise cam means.
