CLINCHING LINEAR SLIDE DEVICE
The present invention permits linear slide motion as well as rotational motion between two sheets or panels of metal. This linear rail system utilizes clinching end stays to hold a loop of wire taut in a milled or stamped slot in a sheet metal panel. The loop of wire is stretched in the milled slot, being wrapped through the undercuts of the clinching end stays. When the stays are pressed into the milled slot with the wire in place, the wire is locked in due to the cold flow of metal around it. The taut spring wire captivates a round follower with flanges above and below the wire runs. The follower is then free to move linearly and rotate in the panel. This follower is self-clinching and can attach a second sheet to the assembly by pressing a hole in the second sheet onto the follower.
1 . A slide assembly, comprising:
a first planar sheet having a circular aperture therethrough;
a follower including clinch means rigidly affixed into said first sheet through said first aperture;
a second panel having an elongate linear slot therethrough, said slot having opposing first and second ends;
two stays, each attached to the second panel at one end of said slot ends;
a flexible elongate wire loop captured by and tensively extending between said stays; and
wherein said follower engages said slot and includes a groove which receives said wire between diametrically opposed sides thereof, thereby joining said first sheet to said second panel rotatably and slidably.
2 . The slide assembly of claim 1 wherein said stays are fixed to said second panel by clinch attachment.
3 . The slide assembly of claim 2 further described in that said first sheet is moveable while said second panel is stationary.
4 . The slide assembly of claim 2 wherein said first sheet and said second panel are composed of metal.
5 . The slide assembly of claim 1 including two followers affixed to said first sheet, each engaging said slot and said wire.
6 . The slide assembly of claim 1 wherein end portions of said wire loop lie within clinch undercuts of said stays.
