Abstract
A collapsible or folding saw is provided as a compact hand tool that when folded covers and protects the blade. The folding saw is movable between an extended useable condition and a folded condition. The saw comprises a frame having a longitudinal telescoping upper member, and first and second collapsible side supports depending from the upper member. A blade is coupled between the first and second collapsible side supports, whereby a tensioning mechanism is provided to tension the blade. Further, a handle is provided having a first portion pivotably coupled to the frame and wherein the handle pivots between a first condition to form a free-end handle and a second handle condition where the handle engages the upper member and encapsulates the blade.

A folding hacksaw movable between an extended useable condition and a folded condition comprising:
- a frame having:
- a longitudinal upper member comprising a first upper member and a second upper member, one or both of said upper members slidable relative to the other upper member in a single degree of freedom in a longitudinal direction, the first and second upper members are constrained from rotating,
- a first collapsible side support depending from a front end of said frame and coupled to the first upper member at a first frame attachment point, and
- a second collapsible side support depending from a back end of said frame and coupled to the second upper member at a second frame attachment point,
- a blade having a first blade end coupled to the first collapsible side support and a second blade end coupled to the second collapsible side support, and
- a handle coupled to the frame having a first handle portion and a second handle portion, and
- an over-centre tensioning mechanism located on the upper member to move the frame between an unlocked position and an over-centre locked position, and
- wherein the over-centre tensioning mechanism moves the first frame attachment point and second frame attachment point away from each other to tension and lock the blade and
- wherein a proximal end of the first handle portion is pivotably coupled to the frame and a distal end of the first handle portion is pivotably coupled to the second handle portion, and
- wherein a distal end of the second handle portion pivots towards the proximal end of the first handle portion to the first handle condition to form a free-end handle.
