Abstract
A fastener for securing two sheets of material each comprises a binding bar having pointed barbs at each end of said binding bar, said barbs each directed substantially perpendicular to said binding bar; a stem fixably attached to said binding bar, means at said stem end to urge said barb ends into said material planar surface. The device is particularly effective to join fire barrier panels without requiring their removal.
Claims14
A panel system, comprising:
- at least two panels, each panel having a top surface and an edge, wherein the panels are abutted adjacent each other along the edges with the top surfaces being generally aligned, and wherein the panels when abutting have a portion removed to define at least one elongate aperture near the edges;
- at least one fastener including an elongate binding bar having first and second barbs, and a stem attached at a first end thereof to said binding bar at a position between said first and second barbs, said stem extending substantially perpendicular to said binding bar;
- wherein the elongate aperture is sized sufficiently to allow the binding bar to pass therethrough, whereby the binding bar can be positioned against the top surfaces bypassing the bar through the elongate aperture from the bottom surfaces and rotating the binding bar about the stem, and wherein said stem is disposed in the aperture with one of said barbs extending into the top surface of one of the panels and another of the barbs extending into the top surface of the adjacent panel;
- and
- means at a second end of said stem for urging said barbs into the top surfaces to secure the panels at the abutting edges.

- at least two panels, each panel having a top surface, a bottom surface, and an edge therebetween, wherein the panels are abutted adjacent each other along the edges with the top surfaces being generally aligned, and wherein the panels when abutting have a portion removed to form at least one elongate slot between the edges, the elongate slot being sized sufficiently to allow the binding bar to pass therethrough, whereby the binding bar can be positioned against the top surfaces by passing the bar through the slot from the bottom surfaces and rotating the binding bar about the stem;
- and
- wherein the stem extends through the slot with one of the barbs extending into the top surface of one of the panels and another of the barbs extending into the top surface of the adjacent panel;
- and
- means at a second end of the stem for urging the barbs into the top surfaces to secure the panels at the abutting edges.
