Abstract

A slide has a pair of identical longitudinally extending and profiled rails each having at least one flange forming two longitudinally extending tracks. The rails are interfitted with the tracks of one rail transversely confronting the tracks of the other rails. Respective longitudinally extending rows of balls engaged in the tracks between the rails.

Claims

1. A slide comprising:

a pair of longitudinally extending and profiled rails of identical section and each having

a center longitudinally extending bight having longitudinally extending first and second edges,

a first flange projecting generally transversely from the first edge;

a second flange projecting generally transversely from the second edge and defining with the first flange a longitudinally extending and transversely open space, the first flange being shaped as an inside hook having an outer leg lying in the space and forming with the first flange a pair of confronting, transversely open, and longitudinally extending tracks, the second flange being shaped as an outside hook having an outer leg lying outside the respective space,

the rails being interfitted with the second-flange outer leg of each rail lying in the space of the other rail, between the tracks of the first flange of the other rail; and

respective longitudinally extending rows of balls engaged in the tracks between the rails.

2. The slide defined in claim 1 wherein the first and second flanges extend transversely in the same direction from the center bight of the respective rail.

3. The slide defined in claim 2 wherein the first flange is shorter than the respective second flange.

4. The slide defined in claim 2 wherein the inside hooks each have an inner leg extending generally parallel to and spaced from the respective outer leg, and a bight portion interconnecting the inside-hook inner and outer legs and extending generally parallel to the center bight.

5. The slide defined in claim 4 wherein the inside hooks each have a connecting inner bight extending at an acute angle to the respective legs and to the center bight, the inner bight connecting the respective inner leg with the respective first edge.

6. The slide defined in claim 2 wherein the second-flange outer leg is generally flat and planar.

7. The slide defined in claim 2 wherein the second-flange outer leg is of flattened S-shape and forms a pair of longitudinally extending second-flange tracks confronting the first-flange tracks.

8. The slide defined in claim 2 wherein the second-flange outer leg is of flattened U-shape and forms a longitudinally extending second-flange track confronting a respective one of the first-flange tracks.

9. The slide defined in claim 2 wherein the second-flange outer leg extends at an acute angle to the respective center bight.
