Abstract

Claims (27)

1 . A hand tool comprising:

a longitudinally extensive handle;

a first coupler half selectively secured to and terminating said handle;

a second coupler half selectively removable from said first coupler half and having a mounting stop,

a threaded tube, a central axis of said threaded tube that defines a second coupler half longitudinal axis, and wherein said threaded tube comprises threads helically wound around said second coupler half longitudinal axis, and

an anti-rotation member displaced radially from said second coupler half longitudinal axis;

an implement affixing knob having a knob body, an outer surface configured to be manually grasped and rotated, and a threaded bore configured to selectively thread on to said threaded tube; and

a fastener passing through a hollow longitudinal internal passage within said threaded tube from said second coupler half to said first coupler half, said fastener selectively securing said first and second coupler halves together;

wherein said fastener further comprises a bolt; and

wherein said first coupler half is located at least in part within said longitudinally extensive handle and comprises a threaded ramped wedge configured to expand radially when said bolt is rotated in a first direction about said second coupler half longitudinal axis and configured to contract radially when said bolt is rotated in a second direction opposite to said first direction about said second coupler half longitudinal axis.

2 . The hand tool of claim 1 , wherein said mounting stop comprises a plate extending in a plane transverse to said second coupler half longitudinal axis.

3 . The hand tool of claim 1 , wherein said threads further comprise a semi-circular thread form.

4 . The hand tool of claim 1 , wherein said threaded ramped wedge comprises:

a first wedge; and

a second wedge;

said first wedge and said second wedge configured to slide relative to each other responsive to said rotation of said bolt.

5 . The hand tool of claim 4 , further comprising a threaded body affixed to said second wedge and threaded about said bolt, wherein said second wedge reciprocates longitudinally along an axis parallel to said second coupler half longitudinal axis responsive to rotation of said bolt.

6 . The hand tool of claim 1 , further comprising an implement head releasably secured between said implement affixing knob and said second coupler mounting stop.

7 . The hand tool of claim 1 , wherein said longitudinally extensive handle comprises at least one cylindrical handle segment; and said hand tool further comprises a plurality of internal ramped cylindrical compression wedges affixing at least one of a handle, an implement, and an offset coupler to said at least one cylindrical handle segment.

8 . The hand tool of claim 7 , further comprising:

an offset connector; and

at least two cylindrical handle segments.

9 . The hand tool of claim 8 , further comprising a terminal hand grip affixed to said longitudinally extensive handle distal to said second coupler half.

10 . The hand tool of claim 1 , wherein said implement affixing knob outer surface further comprises a textured surface.

11 . The hand tool of claim 10 , wherein said implement affixing knob further comprises a longitudinal extension parallel to said second coupler half longitudinal axis, said longitudinal extension having at least one generally flat surface.

12 . The hand tool of claim 1 , wherein said anti-rotation member further comprises a protrusion displaced radially from said second coupler half longitudinal axis and rising from said mounting stop.

13 . The hand tool of claim 1 , wherein said anti-rotation member further comprises a fastener hole formed in said mounting stop and displaced radially from said second coupler half longitudinal axis.
