Abstract
A collapsible multipurpose hand saw is useful for camping, hunting, backpacking, tree pruning, wood cutting and like outdoor uses. The saw comprises two handles, a crosspiece, a saw blade, a tensioning strap and a tensioning rod. The hand saw is easily assembled and disassembled for storage. The saw blade can be mounted in a vertical or horizontal cutting position. The assembled hand saw can be combined with the case to form an emergency snow shovel. The hand saw has no small parts which are easily lost. The saw tensioning strap can be used to carry firewood bundles and can be used as an emergency sling or tourniquet. The handles and crosspiece can be used as emergency splints.
Claims20
A multipurpose outdoor tool comprising:
- a first handle and a second handle parallel to said first handle;
- said first and second handles each having an upper end and a lower end;
- a crosspiece extending between said first handle and said second handle;
- said crosspiece having a first end with a first extending projection, an opposing second end with a second extending projection and an upward facing hole in the middle portion of said crosspiece;
- said crosspiece being beveled on the bottom;
- said first handle having a hole in the middle portion;
- said second handle having a hole in the middle portion;
- said first extending projection fitting into said middle hole of said first handle, and said second extending projection fitting into said middle hole of said second handle;
- a saw blade having a first hole at a first end and a second hole at an opposing second end;
- said first handle having a first retaining pin at the side of the lower end, and having a second retaining pin at the bottom of the lower end;
- said second handle having a first retaining pin at the side of the lower end, and having a second retaining pin at the bottom of the lower end;
- said saw blade first hole fitting onto said first retaining pin of said first handle, and said second hole fitting onto said first retaining pin of said second handle, thereby allowing vertical mounting of the saw blade;
- said saw blade first hole alternatively fitting onto said second retaining pin of said first handle and said second hole fitting onto said second retaining pin of said second handle, thereby allowing horizontal mounting of the saw blade;
- tensioning strap of sufficient length to wrap around the upper end of said first handle and the upper end of said second handle;
- a tensioning rod;
- whereby said tensioning rod may be inserted into said tensioning strap and circularly rotated about an axis parallel to said crosspiece such that said tensioning strap twists and winds up when said tensioning rod is circularly rotated so as to pull the upper ends of said handles toward one another, thereby putting said saw blade under tension by creating a fulcrum at said crosspiece;
- and
- said tensioning rod further comprising removable engagement in said hole in said crosspiece, thereby securing said tensioning strap;
- and
- said tensioning strap further comprising a loop on one end and an opposing free end.

The multipurpose outdoor tool of claim wherein:
- said tensioning strap further comprises a length of at least three feet.
A multipurpose outdoor tool selectively positionable in one of an assembled working mode and a disassembled storage mode, said multipurpose outdoor tool comprising:
- a first handle and a second handle;
- said first and second handles each having an upper end and a lower end;
- a crosspiece beveled toward the bottom;
- said crosspiece having a first end with a first extending projection, an opposing second end with a second extending projection and an upward facing hole in the middle portion of said crosspiece;
- said crosspiece extending perpendicular between said first handle and said second handle when said multipurpose outdoor tool is in its assembled working mode;
- said first handle having a hole in the middle portion;
- said second handle having a hole in the middle portion;
- said first extending projection fitting into said middle hole of said first handle, and said second extending projection fitting into said middle hole of said second handle when said multipurpose outdoor tool is in its assembled working mode;
- saw blade having a first hole at a first end and a second hole at an opposing second end;
- means for mounting said saw blade to said lower ends of said first and second handles in a vertical position or alternatively in a horizontal position when said multipurpose outdoor tool is in its assembled working mode;
- a tensioning strap of sufficient length to wrap around the upper end of said first handle and the upper end of said second handle when said multipurpose outdoor tool is in its assembled working mode;
- a tensioning rod;
- said tensioning rod positionable into the middle portion of said tensioning strap when said multipurpose outdoor tool is in its assembled working mode such that said tensioning strap twists and winds up when said tensioning rod is circularly rotated about the long axis of said tensioning strap so as to pull the upper ends of said handles toward one another, thereby putting said saw blade under tension by creating a fulcrum at said crosspiece;
- said tensioning rod further comprising removable engagement in said hole in said crosspiece, thereby securing said tensioning strap;
- a carrying case for holding said multipurpose outdoor tool when said multipurpose outdoor tool is in the disassembled storage mode;
- said carrying case further comprising means for fastening said carrying case to said multipurpose outdoor tool in the assembled working mode such that said assembled multipurpose outdoor tool can be placed in the carrying case and secured, thereby forming a tool suitable for digging and scooping snow.
