Fastener head cover assembly

Claim 1

A two piece, resilient plastic head cover assembly for decoratively covering the head of a conventional screw, bolt, or the like installed in or through a workpiece, at least a portion of said workpiece being substantially planar, said assembly comprising: an anchor member adapted to be secured in operative position by said screw, bolt or the like upon said planar portion of said workpiece, said anchor member comprising: a planar flange-like base of generally circular cross section having a central orifice defined therein for admitting said screw or the like therethrough, said base having an outer peripheral edge; a bottom comprising a flat underside of said base; an integral peripheral rim rising upwardly from the outer peripheral edge of said base, said rim coaxially surrounding said central orifice, said rim having a top and an external circumferential periphery; a plurality of radially spaced apart petals integrally formed upon said rim, said petals being generally in the form of an inverted conic section intersecting the periphery of said rim, and each of said petals having an outermost inclined edge; and, each of said petals comprising a horizontal top coplanar and contiguous with the top portion of said anchor member base rim and oriented substantially parallel with the planar surface of said workpiece when said assembly is installed upon said workpiece; and, a cup-like, resilient plastic cover plate adapted to be yieldably snap fitted to said anchor member to decoratively cover a head of said screw, fastener or the like, said cover plate comprising: a generally convex top portion; a peripheral downwardly projecting rim integral with said top portion, the last mentioned rim having an internal snap-fit groove defined therewithin for receiving said petals, said snap fit groove having a notch-like cross section conformed generally to frictionally contact the outermost inclined edges of each of said petals whereby to secure said cover plate to said base; and, an expansion groove defined interiorly of said cover plate rim in spaced-apart, generally parallel relation with respect to said snap fit groove and separated therefrom by an apex, said expansion groove adapted to expand said cover plate rim and initially slightly compress said petals when said cover plate is forcibly fitted to said anchor member.
