Abstract

A slide assembly is disclosed herein which comprises a free-sliding member received within a pair of rails. The free-sliding member has a generally Z-shaped cross section, and includes a body and flanges extending from opposite edges of the body. The rails are identical and each includes a channel and retainer flange. The flanges of the free-sliding member are received within and bear against the included channel of the respective rails. The retainer flanges engage projections extending from the body of the free-sliding member, thereby restricting relative sliding movement thereof.

Claims

1. A slide assembly which comprises:

a first rail and a second rail, each of said rails including a channel having first and second sides formed by mutually facing first and second surfaces, each of said rails further comprising a retainer flange extending generally from the first side to the second side, the retainer flange being spaced apart from the second surface and forming an acute angle with a plane parallel to the first surface; and

an elongated, free-sliding member having a generally Z-shaped cross section, the free-sliding member comprising a flat, elongated body having two longitudinal edges and further comprising a first and a second leg, each leg extending from opposite longitudinal edges of the body, the first leg forming an acute angle with a first surface of the body and the second leg forming an acute angle with a second surface of the body, the first leg being received within and bearing against the channel of said first rail, the retainer flange on said first rail being positioned near the second surface of the body, the second leg being received within said bearing against the channel of said second rail, the retainer flange on said second rail being positioned near the first surface of the body.

2. The slide assembly of claim 1 in which each of said rails comprises a first vertical flange having a top and bottom horizontal edge and a second vertical flange, the second vertical flange being attached to one of the horizontal edges of the first vertical flange, the retainer flange being attached to the other of the horizontal edges of the first vertical flange and forming an acute angle therewith.

3. The combination of:

a support structure;

a sliding structure operable to move relative to said support structure; and

the slide assembly of claim 1, one of said rails being attached to said support structure and the other of said rails being attached to said sliding structure.

4. The combination of claim 3 which further comprises a second slide assembly, said second slide assembly comprising a third rail and a fourth rail, each of said third and fourth rails including a channel having first and second sides formed by mutually facing first and second surfaces, each of said third and fourth rails further comprising a retainer flange extending generally from the first side to the second side, the retainer flange being spaced apart from the second surface and forming an acute angle with a plane parallel to the first surface, said second slide assembly further comprising a second, elongated, free-sliding member comprising a flat, elongated body having two longitudinal edges and further comprising a first and a second leg, each leg of the second free-sliding member extending from opposite longitudinal edges of the body of the second free-sliding member, the first leg forming an acute angle with a first surface of the body of the second free-sliding member and the second leg forming an acute angle with a second surface of the body of the second free-sliding member, the first leg being received within and bearing against the channel of said third rail, the retainer flange on said third rail being positioned near the second surface of the body of the second free-sliding member, the second leg being received within and bearing against the channel of said fourth rail, the retainer flange on said fourth rail being positioned near the first surface of the body of the second free-sliding member, one of said rails of said second slide assembly being attached to said support structure and the other of said rails of said second slide assembly being attached to said sliding structure.

5. The combination of claim 4 in which each of said rails comprises a first vertical flange having a top and bottom horizontal edge and a second vertical flange, the second vertical flange being attached to one of the horizontal edges of the first vertical flange, the retainer flange being attached to the other of the horizontal edges of the first vertical flange and forming an acute angle therewith.

6. The combination of claim 5 in which each of said rails comprise a single piece of sheet metal, the sheet metal being bent to form the three flanges.

7. The combination of claim 6 in which said rails are identical.

8. The combination of claim 7 in which all of the acute angles are approximately equal.

9. The combination of claim 8 in which said rails further comprise stop means for preventing at least one of said free-sliding members from sliding relative said rails beyond a preselected point.

10. The combination of claim 8 in which said stop means includes a first projection extending from one surface of the body of said free-sliding member near one end and a second projection extending from the other surface of the body of said free-sliding member near the other end, each projection being engaged by the retainer flange positioned near the surface of the body from which the projection extends when the rail which includes the retainer flange is slid relative the free-sliding member in the direction of the projection.
