Abstract
A screw form anchor device (10) intended for screwed penetration into a host material. The anchor device (10) includes a body (11) having a manipulating end (12) and a distal end (13). A screw thread (22) is formed by a plurality of tapering angular helix thread forms (22a) which extend from the distal end. Each angular helix thread form (22a) has an outward facing surface (24) and, relative to the distal end, a downward facing surface (25). In the preferred form an emergent helix thread (26) commences from a point distant from the distal end (13). This emergent helix thread (26) extends toward the manipulating end (12) of the body (11).
Claims22
A screw form anchor device (10) including a body (11) having a manipulating end (12) and a distal end (13), a screw thread (22) formed by a plurality of tapering angular helix thread forms (22a) extending away from said distal end (13) toward said manipulating end (12), each angular helix thread form (22) having an outward facing surface (24) and, relative to the distal end, a downward facing surface (25).
An anchor device as claimed in any one of the preceding claims wherein an emergent helix thread (26) commences from a point distant from the distal end (13) and extends toward the manipulating end (12).
An anchor device as claimed in any one of the preceding claims wherein all vertices associated with the angular helix threads (22a) and emergent helix thread (26) are rounded.
