attachment means for attaching said anchoring plate to said structure;
a cap for securing the roof membrane to said anchoring plate by inserting the roof membrane in said cylindrical axial opening and snapping said cap in said cylindrical axial opening thereby interlocking said cap and said anchoring plate, said cap comprising;
a cylindrical body having a top end, a bottom end, an outer wall, an inner wall and a longitudinal axis, said inner wall defining a downwardly opening cylindrical cavity concentric about said longitudinal axis, said outer wall having a first outside diameter;
a V-shaped flange tapering inwardly from a top to a bottom attached to the bottom end of said cylindrical body and extending radially beyond said outer wall around the entire circumference of said cylindrical body, said V-shaped flange and said cylindrical body having a greatest diametrical dimension at said top;
a compression cut extending longitudinally through the cylindrical body and the V-shaped flange said compression cut having sides;
a second disk attached to the top end of said cylindrical body and concentric about said longitudinal axis, said second disk having a second outside diameter greater than the greatest diametrical dimension of said cylindrical body and said V-shaped flange; and
,said cap having a first state wherein said greatest diametrical dimension is slightly greater than said second inside diameter and slightly less than said first inside diameter and wherein said first outside diameter is slightly less than said second inside diameter, said cap also having a second state wherein said greatest diametrical dimension is slightly less than said second inside diameter.

Abstract
A roof membrane anchoring system in accordance with the present invention includes an anchoring plate with a substantially planar bottom surface and convexly radiused top surface that can be attached to an existing structure. The anchoring plate is disk-shaped and has a cylindrical axial opening in the center into which a lip and a bottom flange extend to form a channel. A cap with a resilient cylindrical body having V-shaped flanges at the bottom and either a disk or ring attached to the top is inserted into the anchoring plate once a roofing membrane is inserted into the axial opening in the plate. The resilient cylindrical body has a cylindrical cavity therein and compression cuts which extend through the body and to the V-shaped flange to allow for the resilient body to assume a first state wherein the greatest diametrical dimension of the resilient cylindrical body and the V-shaped flange is slightly less than the inside diameter of the lip extending into the axial opening. These compression cuts then allow the body to expand to a first state wherein diametrical dimension of the resilient body is slightly less than the inside diameter of the lip which extends into the axial opening. One modification of the anchoring system is to use a plug which may be inserted into the cap after the cap has assumed its first state so that the cap is locked into the first state and cannot inadvertently be removed from the anchoring plate.
