Abstract

An injection-molded plastic roofing membrane plate includes a body and multiple cleats. The cleats extend from a bottom surface of the body. Each of the cleats has a rounded terminal end with a rounded terminal surface. The rounded terminal surfaces make surface-to-surface abutment with an underlying membrane in installation. The rounded terminal surfaces reduce wear on the underlying membrane that may otherwise occur.

Claims (13)

1. An injection-molded plastic roofing membrane plate, comprising:

a body;

wherein said body has a bore defined therethrough, said bore constructed for receiving a fastener;

wherein said body has a central region with a substantially uniform thickness dimension, and said body has a peripheral region spanning from said central region and having a tapered thickness dimension narrowed in dimension toward a periphery of said body; and

a plurality of cleats extending from a bottom surface of said body, each of said plurality of cleats having a rounded terminal end with a rounded terminal surface, said rounded terminal surfaces making surface-to-surface abutment with an underlying membrane in installation and at least reducing wear on the underlying membrane via said plurality of cleats.

2. The injection-molded plastic roofing membrane plate of claim 1 , wherein each of said plurality of cleats has a tapered portion spanning from said rounded terminal end, said tapered portion narrowing in dimension toward said rounded terminal end.

3. The injection-molded plastic roofing membrane plate of claim 2 , wherein each of said plurality of cleats has a base portion spanning from the bottom surface of said body to said tapered portion, said base portion having a substantially uniform dimension throughout its extent from the bottom surface to said tapered portion.

4. The injection-molded plastic roofing membrane plate of claim 1 , wherein each of said plurality of cleats extend unitarily from said body at the bottom surface and are free of a hinge thereat.

5. A method of manufacturing a plastic roofing membrane plate, the method comprising:

injection molding the plastic roofing membrane plate to have a body and a plurality of cleats extending from said body, said body having a single bore defined therethrough and having a tapered thickness dimension narrowed in dimension toward a periphery of said body, each of said plurality of cleats having a rounded terminal end, having a tapered portion spanning from said rounded terminal end, and having a base portion spanning from said tapered portion that has a substantially uniform dimension throughout its extent.

6. An injection-molded one-piece plastic roofing membrane plate, comprising:

a body having a bore defined therethrough for receiving a fastener, said body having a peripheral region that is narrowed in dimension toward a periphery of said body; and

a plurality of cleats spanning unitarily from said body at a bottom surface of said body, each of said plurality of cleats having a rounded terminal end with a rounded terminal surface, said rounded terminal surfaces making surface-to-surface abutment with an underlying membrane in installation, each of said plurality of cleats having a tapered portion spanning generally from said rounded terminal end, said tapered portion narrowing in dimension toward said rounded terminal end, and each of said plurality of cleats having a base portion spanning generally from the bottom surface of said body and generally to said tapered portion, said base portion having a substantially uniform dimension throughout its extent from the bottom surface and to said tapered portion.
