Abstract: A connector insert is installed into two panels, one non-metallic and one metal, effectively locking them together and finishing flush with the surfaces of each panel. Both sheets have aligned apertures through which the connector is installed. The connector is a clinch-type fastener including a shank having a displacer head at one end and an endface at the opposite end, the head having a planar top surface and being the largest diameter of the fastener. An undercut groove is located on the shank immediately below the head and a plurality of axially-extending broaching teeth on the shank are located immediately below the undercut groove. The diameter of the broaching teeth is greater than the diameter of the undercut groove but less than the diameter of the head. At the end of the shank is a planar endface immediately below the broaching portion.

Abstract: 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.

Abstract: A double flush clinch stud includes adjacent clinch means of different diameters with planar end surfaces. The stud may be employed in forming an assembly wherein two metal sheets are joined in face-to-face contacting relationship. This assembly can provide a flush attachment on the outside surfaces of both sheets when the length of the stud is equal to the combined widths of the sheets. In an alternative embodiment, the top undercut groove can be adapted to be underfilled with the material of the top sheet. In this alternate configuration, the top sheet is effectively constrained between the head of the fastener and the second sheet while permitting the top sheet to pivot with respect to the second sheet.
