Claims Analysis

Total Claims: 11
Claim 1
Independent Claim 204 words
A unitary fastener plate for use with a fastener in a roof structure, said fastener comprising: (a) a generally disc-shaped plastic member having a generally planar upper face and a generally planar lower face and having an essentially flat-bottomed central portion depending from said lower face and a flange depending from said lower face along the peripheral zone of said plastic member a distance essentially the same as the distance said central portion depends from said lower face of said plastic member and having an opening therein extending from said upper face of said plastic member downwardly through said central portion depending from said lower face of said plastic member; (b) a metal insert seated in said opening within said plastic member and having an opening extending therethrough in communication with the first said opening to provide an opening through said fastener plate through which said fastener can be threaded, the side surface of said opening in said metal insert sloping inwardly as said surface extends downwardly to provide a generally conical-shaped countersink in the upper surface of said metal insert; and (c) retainer means for retaining said metal insert firmly seated within said opening in said plastic member to form a unitary structure.
Claim 2
Dependent Claim 204 words
A unitary fastener plate for use with a fastener in a roof structure, said fastener comprising: (a) a generally disc-shaped plastic member having a generally planar upper face and a generally planar lower face and having an essentially flat-bottomed central portion depending from said lower face and a flange depending from said lower face along the peripheral zone of said plastic member a distance essentially the same as the distance said central portion depends from said lower face of said plastic member and having an opening therein extending from said upper face of said plastic member downwardly through said central portion depending from said lower face of said plastic member; (b) a metal insert seated in said opening within said plastic member and having an opening extending therethrough in communication with the first said opening to provide an opening through said fastener plate through which said fastener can be threaded, the side surface of said opening in said metal insert sloping inwardly as said surface extends downwardly to provide a generally conical-shaped countersink in the upper surface of said metal insert; and (c) retainer means for retaining said metal insert firmly seated within said opening in said plastic member to form a unitary structure.
Claim 3
Dependent Claim 25 words
The fastener plate of claim 1 wherein said depending flange member is an uninterrupted member extending along the entire peripheral zone of said plastic member.
Claim 4
Dependent Claim 32 words
