Abstract

Claims20
An anchor nail fastener for use with roof deck systems having composite materials comprising;
- a tubular sheet metal shank defining a hollow cavity which extends from an open upper end toward a penetrating end thereof,
- a pair of generally opposing openings in said shank spaced from said penetrating end thereof,
- said shank being formed tapering outwardly from said penetrating end and beyond said opposing openings toward said upper end such that a tapered portion of said shank intermediate said opposing openings and said upper end will compact a composite material in an area adjacent to said opposing openings when said shank is driven into a wedged engagement therein, and
- a generally U-shaped locking staple having bendable leg portions each having a free end of a size to pass through one of said opposing openings in said shank.
An anchor nail fastening system for use with roof decks having composite materials comprising;
- a plurality of tubular sheet metal shanks of separate lengths, each shank defining a hollow cavity which extends from an open upper end toward a penetrating end thereof,
- a pair of generally opposing openings in each shank spaced from said penetrating end thereof,
- each shank tapering outwardly from said penetrating end and beyond said opposing openings toward said upper and such that a tapered portion of said shank intermediate said opposing openings and said upper end will compact a composite material in an area adjacent to said opposing openings when said shank is driven into a wedged engagement therein,
- a plurality of generally U-shaped locking staples of substantially the same size and configuration and each having bendable leg portions having a free end of a size to pass through one of said opposing openings in one of said shanks, and
- each of said leg portions including inwardly oriented and generally opposing bent segments which engage one another as one of said locking staple is driven into one of said shanks so as to drive said free ends of said leg portions through said opposing openings to thereby inhibit said locking staple from backing out of said cavity through said upper end of said shank.
