Patent ID: 7441378

Claim:
A cover for covering a deck plank, said deck plank having a top surface, two side surfaces, and two lower radial portions, said cover comprising: a top portion which has a length and width and covers said top surface of said deck plank, said top portion having an outer surface which is remote from said deck plank, an inner surface which is adjacent said deck plank; two side portions, each of which has a length and a height and covers one of said side surfaces of said deck plank, said side portions attached to said top portion such that the length dimension of said top portion and said side portions coincide, both of said side portions projecting from said top portion in a direction generally opposite that of said outer surface of said top portion and at angles that deviate from perpendicular such that each of said side portions angles inward toward each other, the inward angle providing said cover with a frictional adhesion to said two side surfaces of said deck plank; and wood engaging fillets attached to the edges of said side portions which are distant from the top portion, said fillets curving radially inward toward each other and not extending parallel to said top portion beyond the radius of curvature of said fillets, thus said fillets are designed to grip only said lower radial portions of said deck plank thereby providing for additional frictional adhesion to said deck plank.
