HAND SAW

摘要

A hand saw including a blade, a frame that supports the blade, and a tensioning mechanism. The frame including a first leg having a first blade support, a second leg spaced from the first leg, a cross member extending between the first leg and the second leg, and a handle. The tensioning mechanism including a bracket having a second blade support, the bracket pivotable with respect to the frame in a first direction to increase a distance between the blade supports and in an opposite direction to decrease the distance between the blade supports, a lever actuatable between a tension position and a release position, and a linkage that couples the lever to the bracket such that movement of the lever towards the tension position pivots the bracket in the first direction, and movement of the lever towards the release position pivots the bracket in the second direction.

主权项

1. A hand saw comprising:
a blade including a first end, a second end, and a longitudinal axis that extends between the first and second ends; a frame that supports the blade, the frame including
a first leg having a first blade support that removably couples the first end of the blade to the frame,a second leg spaced from the first leg,a cross member extending between the first leg and the second leg, anda handle configured to be grasped to reciprocate the blade along the longitudinal axis to cut a workpiece; and a tensioning mechanism including
a bracket pivotally coupled to the frame and having a second blade support that couples the second end of the blade to the frame, the bracket pivotable with respect to the frame in a first direction to increase a distance between the first and second blade supports and in a second, opposite direction to decrease the distance between the first and second blade supports,a lever actuatable between a tension position and a release position, anda linkage that couples the lever to the bracket such that movement of the lever towards the tension position pivots the bracket in the first direction to apply tension to the blade, and movement of the lever towards the release position pivots the bracket in the second direction to release tension from the blade.
