Abstract: A tack button utilizes a pivot tack that has a long taper on its shank which prevents buckling and a subsequent loose connection of the assembled button parts, particularly the assembly of the back member of the button with the fabric to which the button is being attached. The long tapered shank curls as the assembly process is carried out so that a curled structure is within the button shell and is positioned to clinch the back member to the fabric.

Abstract: A panel retainer comprises a one-piece, integrally formed member, formed from a resilient, elastically bendable material, and having a fastener-receiving portion and a panel-gripping portion. The fastener-receiving portion comprises a body portion having a top surface and a substantially flat bottom surface spaced from the top surface and defining a through aperture for receiving a fastener to secure the retainer to a given surface. The panel-gripping portion comprises a further body portion projecting from the first body portion and having a tapered surface portion diverging from the first body bottom flat surface for engagement with a panel to be retained thereby. The gripping portion is flexible in the area where it joins with the fastener-receiving portion to permit resilient, elastic bending thereof for engagement of the tapered surface in a surface-to-surface engagement with the panel.
