Abstract
A drawer slide member including raceways formed of folded or solid material providing additional thickness while utilizing thin material may provide for increased strength of the drawer slide.
Claims10
A friction drawer slide, comprising:
- an outer slide member having a longitudinal web bounded by inwardly facing arcuate raceways;
- an inner slide member having a longitudinal web bounded by outwardly facing arcuate raceways;
- and
- an intermediate slide member, the intermediate slide member extendably coupled to the inwardly facing arcuate raceways of the outer slide member, the intermediate slide member extendably coupled to the outwardly facing arcuate raceways of the inner slide member, the intermediate slide member having a longitudinal web bounded by inward facing arcuate raceways, with abutments extending outwardly from about edges of material forming the inward facing arcuate raceways, and outward facing arcuate raceways between the abutments, and an extra layer of material abutting an outer surface of the inward facing raceways;
- wherein the intermediate slide member is extendably coupled to the outer slide member by at least one friction rod in the inwardly facing arcuate raceways of the outer slide member and outward facing arcuate raceways of the intermediate slide member, and the intermediate slide member is coupled to the inner slide member by at least one further friction rod in the outwardly facing arcuate raceways of the inner slide member and inward facing arcuate raceways of the intermediate slide member.

A friction drawer slide, comprising:
- an outer slide member having a longitudinal web bounded by inwardly facing arcuate raceways;
- an inner slide member having a longitudinal web bounded by outwardly facing arcuate raceways;
- and
- an intermediate slide member having:
- a longitudinal web longitudinally bounded by inward angled bends forming inward frictional contact surfaces for riding in the outwardly facing arcuate raceways of the inner slide member, and
- outward frictional contact surfaces for riding in the inwardly facing arcuate raceways of the outer slide member, wherein the outward frictional contact surfaces are each formed in a hemmed edge.

A friction drawer slide, comprising:
- an outer slide member having a longitudinal web bounded by inwardly facing arcuate raceways;
- an inner slide member having a longitudinal web bounded by outwardly facing arcuate raceways;
- an intermediate slide member extendably coupling the outer slide member and the inner slide member, the intermediate slide member including a longitudinal web bounded by triangular lobes, with an apex of each of the triangular lobes providing an outward frictional contact to ride in the inwardly facing arcuate raceways of the outer slide member and a base of each of the triangular lobes providing an inward frictional contact to ride in the outwardly facing arcuate raceways of the inner slide member;
- and
- a protruding ledge proximate the base of each triangular lobe, each corresponding protruding ledge and base providing a notch to receive a corresponding flange of the inner slide member providing the outwardly facing arcuate raceways.
2 more elements
An intermediate drawer slide member for use in a friction drawer slide, the intermediate slide member comprising:
- a longitudinal web,
- opposing lobes longitudinally bounding the longitudinal web, the opposing lobes having a generally oval cross-section;
- wherein the opposing lobes are attached to the longitudinal web by way of fasteners.
