Abstract:
1. A fastener for attaching two panels having aligned apertures, comprising: an elongate retainer having a longitudinal axial bore, a base at one end, and a mouth at an opposite end; an attachment means for rigidly affixing the retainer to a first panel; a first cam integral with said retainer, said cam radially disposed around the mouth of said retainer and extending longitudinally therefrom; a shaft having a head at one end, said shaft extending through said bore and beyond the base of said retainer; a second cam in frictional engagement with said first cam, said second cam extending longitudinally from an underside of said head of said shaft; an elastomeric sleeve located around a portion of said shaft which extends beyond the base of said retainer, said sleeve having an outside diameter greater than said bore and being in axial abutment with said base; and a cap affixed to a second end of said shaft, said cap being in abutment with the sleeve whereby rotation of said shaft causes retraction of said shaft from the mouth of the retainer and bulging of said elastomeric sleeve such that when said fastener is installed through aligned apertures in the first panel and a second panel, a bulge created by turning the shaft applies an axial clamp force against an opposite side of the second panel.
