Abstract
An articulating plate assembly for retaining sheets of roofing material on a roof surface includes a plate defining (i) a generally hemispherically-shaped recess in a central portion of a first surface thereof, and (ii) an aperture disposed in the recess and extending through the plate, and a fastener having (i) a shank portion configured to pass through the aperture and to engage the roof surface, and (ii) a head portion having an underside of a curved configuration generally complementary to the recess.
Claims31
An articulating plate assembly for retaining sheets of roofing material on a roof surface, said assembly comprising:
- a plate defining (i) a generally hemispherically-shaped recess in a central portion of a first surface thereof, and (ii) an aperture disposed in said recess and extending through said plate, wherein said plate is provided with an upstanding crown on the first surface thereof and said recess is disposed centrally of said crown;
- and
- a fastener having (i) a shank portion configured to pass through said aperture and to engage the roof surface, and (ii) a head portion having an underside of a curved configuration generally complementary to said recess.
An articulating plate assembly for retaining sheets of roofing material on a roof surface, said assembly comprising:
- a plate defining (i) a generally hemispherically-shaped recess in a central portion of a first surface thereof, and (ii) an aperture disposed in said recess and extending through said plate, wherein said plate is provided with a generally planar second surface, a peripheral portion of said second surface sloping toward said first surface;
- and
- a fastener having (i) a shank portion configured to pass through said aperture and to engage the roof surface, and (ii) a head portion having an underside of a curved configuration generally complementary to said recess.
An articulating plate assembly for retaining sheets of roofing material on a roof surface, said assembly comprising:
- a plate defining (i) a generally hemispherically-shaped recess in a central portion of a first surface thereof, and (ii) an aperture disposed in said recess and extending through said plate;
- and
- a fastener having (i) a shank portion configured to pass through said aperture and to engage the roof surface, and (ii) a head portion having an underside of a curved configuration generally complementary to said recess;
- wherein said plate is of an elongated configuration, said aperture is elongated, and a lengthwise axis of said aperture extends transversely of a lengthwise axis of said plate.

A roof structure comprising:
- a deck of rigid material;
- a sheet of elastomeric material disposed over said deck;
- a sheet of roof membrane material disposed over said sheet of elastomeric material;
- and
- a plate assembly disposed on said roof membrane material for retaining said sheet of roof membrane material, said plate assembly comprising:
- a plate defining (i) a generally hemispherically-shaped recess in a central portion of a first surface thereof, and (ii) an aperture in said recess and extending through said plate, wherein said plate is provided with an upstanding crown on the first surface thereof and said recess is disposed centrally of said crown, and
- a fastener having (i) a shank portion extending through said aperture and engaging said deck, and (ii) a head portion disposed in said recess and having an underside of a curved configuration generally complementary to said recess;
- wherein upon lifting of said roof membrane sheet, said plate is pivotally movable about said fastener head portion, and said sheet of elastomeric material permits the movement of said plate.
