Abstract
The present invention relates to an extendable folding saw that is lightweight and compact when retracted yet rigid when extended. In one embodiment, the extendable folding saw can have a folding saw and a removably attached extension. The folding saw can have a grip and a pivotally attached saw. The extension can comprise several members that are compactable to a length not much greater than the length of the longest individual member. The members of the extension can have a generally I shaped profile. The extension rod can be attached to the folding saw in a snap-fitting manner for use. A retracted folding saw can be snapped side-by-side to a retracted to extension rod for storage.
Claims18
A pole saw comprising:
- a pole assembly including an elongate pole having a proximal end portion, a distal end portion, and a longitudinal center axis, the elongate pole including a plurality of pole sections, the plurality of pole sections including a first pole section and a second pole section, the elongate pole having an extended configuration and a retracted configuration, the first pole section being movable with respect to the second pole section for changing the configuration of the elongate pole between the extended and retracted configurations;
- a saw including a blade and a blade support, the blade including a cutting edge adapted for cutting, the blade support including a proximal end and a distal end opposite the proximal end, the blade having a proximal end, a distal end, and a length extending therebetween, the proximal end of the blade being connected to the distal end of the blade support, the blade support including a cavity in which the pole assembly is receivable for mounting the folding saw on the pole assembly, the cavity having an opening at the proximal end of the blade support, said opening facing away from the distal end of the blade support, the cavity extending distally in the blade support toward the distal end of the blade support, the cavity opening out of the blade support on opposing sides of the blade support to define first and second side openings in the opposing sides of the blade support, the first and second side openings extending from the opening of the cavity at the proximal end of the blade support distally along the blade support toward the distal end of the blade support;
- wherein the pole assembly includes an anchor configured to mate with the blade support to mount the folding saw on the pole assembly, the anchor including a transverse part having a first end portion, a second end portion, and a length extending therebetween generally transverse to the longitudinal center axis of the elongate pole, the anchor including an abutment part at the first end portion of the transverse part, the abutment part defining an abutment surface facing toward the second end portion of the transverse part, the transverse part being receivable in the cavity and side openings of the blade support and the abutment surface being located to abut the blade support to mount the saw on the pole assembly;
- wherein when the anchor is mated with the blade support to mount the saw on the pole assembly:
- the first end portion of the transverse part is received in the first side opening;
- the second end portion of the transverse part is received in the second side opening;
- the anchor inhibits the blade support from separating from the pole assembly in a direction extending distally away from the distal end of the elongate pole;
- the abutment part at least partially overlies an edge of the first side opening and an outer surface of the blade support facing laterally with respect to the longitudinal center axis of the elongate pole and away from the second side opening;
- the abutment surface abuts said outer surface of the blade support;
- the elongate pole extends from the proximal end portion of the elongate pole to the distal end portion of the elongate pole in a direction toward the blade, the blade support extends from the proximal end of the blade support to the distal end of the blade support in a direction away from the proximal end portion of the elongate pole, and the blade extends from the distal end of the blade support.
