Abstract
A tool is provided. The tool may include a handle, a frame, and a removable saw blade including at least one hole on one end thereof and at least one hole on another end thereof. The tool may also include a compensating clip configured to attach the removable saw blade to the frame and to provide tension for the removable saw blade. The compensating clip may include a plate including a clip hook, and the plate further includes an opening where a compensator spring is provided. The clip hook is configured to attach onto the at least one hole of the removable saw blade to attach the saw blade to the frame.
Claims14
A saw comprising:
- a frame;
- a handle connected to the frame;
- a saw blade extending between the handle and the frame;
- a compensating clip;
- and
- a bale connecting the compensating clip to the frame;
- wherein a first end of the saw blade is fixedly mounted to one of the handle and the frame, and a second end of the saw blade is linked to the other of the handle and the frame by the compensating clip;
- wherein the compensating clip includes:
- a retention structure;
- a clip member received by the retention structure, the clip member having a clip hook removably received in a hole in the second end of the saw blade;
- and
- a compensator spring acting between the clip member and the retention structure to apply a tensioning force to the saw blade;
- wherein the bale is pivotally mounted to the frame to rotate relative to the frame about a bale rotation axis, and the compensating clip is pivotally mounted to the bale to rotate relative to the bale about a clip rotation axis spaced apart from the bale rotation axis, wherein the bale is rotatable to a closed position such that tension is applied to the saw blade by way of the compensating clip;
- and
- wherein the retention structure, the clip member, and the compensator spring of the compensating clip rotate with the bale relative to the frame when the bale is rotated to the closed position;
- wherein the retention structure and the clip member include respective overlapping openings, and the compensator spring is received in the overlapping openings;
- and wherein the retention structure is a U-shaped bracket defining a central slot, and the clip member is an elongated plate received by the central slot of the retention structure.
A saw comprising:
- a frame having a proximal end and a distal end;
- a handle mounted to the proximal end of the frame;
- a bale pivotally mounted to the distal end of the frame for rotation relative to the frame about a bale rotation axis;
- a compensating clip pivotally mounted to the bale for rotation relative to the bale about a clip rotation axis, the compensating clip including a retention structure, a clip member received by the retention structure, and a compensator spring acting between the clip member and the retention structure;
- and
- a saw blade having a first end removably mounted to the handle and a second end removably mounted to the compensating clip;
- wherein the bale is rotatable relative to the frame to a closed position such that tension is applied to the saw blade by way of the compensator spring, wherein the retention structure, the clip member, and the compensator spring of the compensating clip rotate with the bale relative to the frame when the bale is rotated to the closed position;
- wherein the retention structure and the clip member include respective overlapping openings, and the compensator spring is received in the overlapping openings;
- and wherein the retention structure is a U-shaped bracket defining a central slot, and the clip member is an elongated plate received by the central slot of the retention structure.
