초록 ▼

A self-centering wall anchor 10, 100 having an outwardly threaded hollow cylindrical body 101, 111 with a flanged proximal end and a cutting distal end. The hollow cylindrical body diminishes in diameter toward the distal cutting end 20, 110 in the form of a pointed dome with a pointed centering tip 22, 103 at the center axis of the anchor. An inner bore 14, 105 extends continuously from its opening at the proximal end of the anchor along the center axis of the cylindrical body to the centering tip at the distal end where it is partially closed because of the disposition of the centering tip at the center axis. The distal end of the bore is in the form of a deep flute 21, 105a which communicates and is part of the inner bore and is defined at its outer edges by a leading cutting edge 23, 107 and a trailing edge 24, 108 of the single cutter, with the leading cutting edge extending from the pointed tip in a curved distention. In one instance, the outer thread extends to the centering tip and is interrupted in the area of the bore opening to assure optimum access to material cut from the wall as the anchor is rotated.

대표청구항 ▼

[ I claim:] [1.] A wall anchor for insertion in wall board material, said wall anchor comprising a cylindrical body extending along a center axis and having a radially extending flange at a proximal end, said cylindrical body diminishing in diameter along a distal cutting end and forming a pointed dome with a centering tip disposed at the center axis of said anchor, an outer thread extending substantially along the length of said cylindrical body and an axial passage extending from an opening at said proximal end of said body to an opening at said distal cutting end of said body where said axial passage is partially closed because of the diminishing diameter of said cylindrical body and the disposition of said centering tip at the center axis of said anchor, means extending axially along said axial passage from said proximal end for receiving and for being tapped by the threads of a screw fastener, recess means at said proximal end for receiving a drive tool for rotating said anchor for cutting through the wall board with said distal cutting end, said opening of said axial passage at said distal cutting end of said anchor extending along only one side of said distal cutting end and comprising access means along said only one side of said distal cutting end communicating with said axial passage for passing material cut from the wall board into said axial passage, said opening of said axial passage at said distal end of said anchor being defined by a leading edge and a trailing edge of a single cutter, said edges extending from said centering tip in diverging spiral paths, said outer thread extending from said proximal end adjacent said flange to adjacent said single cutter and comprising means for tapping the wall board material and for pulling said anchor through the wall board material as said single cutter rotates without drilling a hole through the wall board in advance of said thread, said outer thread having a high turn adjacent said flanged proximal end, said high turn and said flanged end comprising means, when embedded in the wall material because of rotation of said anchor, for compressing wall material for resisting further distal movement of said anchor when a screw fastener is tapping said means for receiving and for being tapped by the threads of a screw fastener.
