STRAP WRENCH
A strap wrench comprising a gripping member, a flexible member, an end of the gripping member comprising a first slot for receiving the flexible member, a locking member engagable within a flexible member wrap portion, the flexible member wrap portion and locking member having an interference engagement within the first slot, a second slot parallel to the first slot for receiving another end of the flexible member, and the locking member having a tapered cross-sectional form and having a surface texture for frictionally engaging the flexible member wrap portion within the first slot.
1 . A strap wrench comprising:
a gripping member ( 10 );
a flexible member ( 150 );
an end of the gripping member comprising a first slot ( 51 ) for receiving the flexible member;
a locking member ( 151 ) engagable within a flexible member wrap portion ( 152 );
the flexible member wrap portion and locking member having an interference engagement within the first slot;
a second slot ( 52 ) parallel to the first slot for receiving another end of the flexible member; and
the locking member having a tapered cross-sectional form and having a surface texture ( 156 ) for frictionally engaging the flexible member wrap portion within the first slot.
2 . The strap wrench as in claim 1 further comprising a textured surface disposed adjacent to the first slot for engaging the flexible member.
3 . The strap wrench as in claim 1 , wherein the flexible member comprises a multi-ribbed belt.
4 . The strap wrench as in claim 1 , wherein the end extends normally from the end of the gripping member.
5 . The strap wrench as in claim 2 , wherein the second slot is disposed between the first slot and the textured surface.
6 . The strap wrench as in claim 1 , wherein the locking member major axis is oriented parallel to a flexible member tensile load vector.
7 . The strap wrench as in claim 1 , wherein the surface texture comprises parallel elongate grooves extending normal to the taper direction.
8 . A strap wrench comprising:
a gripping member having a first slot disposed radially outward from a gripping member axis;
a flexible member;
a locking member having a predetermined cross-sectional form and having a plurality of elongate grooves for gripping the flexible member within the first slot; and
a second slot for receiving another end of the flexible member, the second slot disposed between the first slot and the gripping portion axis.
9 . A strap wrench comprising:
a gripping member having a first slot, and a second slot parallel to the first slot;
a flexible member having a flexible member wrap portion receivable by the first slot, the flexible member receivable by the second slot; and
a locking member having a surface texture feature for an interference fit when engaged with the flexible member wrap portion within the first slot.
10 . The strap wrench as in claim 9 , wherein the flexible member comprises a multi-ribbed belt.
11 . The strap wrench as in claim 9 , wherein the surface texture feature comprises a plurality of grooves.
12 . The strap wrench as in claim 9 , wherein the locking member comprises a tapered form.
13 . The strap wrench as in claim 9 , wherein the locking feature comprises a triangular form.
14 . The strap wrench as in claim 9 further comprising a ribbed surface adjacent the second slot.
15 . The strap wrench as in claim 9 , wherein the gripping member further comprises a knurled surface.
16 . The strap wrench as in claim 9 , wherein the second slot is disposed between the first slot and the gripping member.
17 . The strap wrench as in claim 9 , wherein the first slot is disposed radially outward from the second slot with respect to a gripping member axis (A-A).
18 . The strap wrench as in claim 9 , wherein the first slot is wider at one end.
19 . The strap wrench as in claim 9 , wherein the flexible member comprises tensile cords.
20 . The strap wrench as in claim 9 , wherein an end of the flexible member is disposed for pressing engagement against the gripping member.
