ABSTRACT:
A molded one-piece elastomeric anchor member for securing and apertured workpiece to a mating edge of a normally extending panel by means of a fastener. The anchor member has an elongated body comprising a pair of opposed arcuate wall portions defining a central bore for receiving a threaded shank of the fastener. The arcuate wall portions are interrupted by a pair of diametrically opposed living hinge gaps bridged by an arcuate web portion and a wedge-shaped portion, respectively. A cut-out, formed in the panel mating edge, is adapted to receive the anchor member therein. A flange section extends from each juncture of the web portion with the body so as to contact one side of the panel. The wedge-shaped portion defines a pair of cam shoulders adapted to snap outwardly and lock the anchor member in the cut-out after being manually compressed about its living hinges during insertion in the cut-out. Upon the threaded shank being inserted through the workpiece aperture and threaded in the central bore the anchor member is mechanically locked in the panel cut-out while the workpiece is secured to the panel mating edge.
