Abstract
A saw can include a guide for guiding a saw blade. In one embodiment, the guide can be moveable between an active position wherein the guide guides a saw blade and an inactive position wherein the guide does not guide the saw blade. In one embodiment, the guide in the active position limits lateral movement of the blade, and the guide defines a clearance between the guide and the blade, the clearance having a height greater than a height of the blade, the saw being configured so that during cutting at least a portion of the article being cut can be accommodated within the clearance without contacting the guide.
Claims38
A saw for cutting an article, said saw comprising:
- an elongated saw blade having a proximal end and a distal end;
- a driver assembly for moving said elongated saw blade;
- a housing encapsulating said driver assembly;
- and
- a guide for guiding said elongated saw blade, the saw being configured so that said guide is moveable between an active position and an inactive position, the guide in said active position limiting lateral movement of said elongated saw guide blade, the guide in said inactive position not limiting lateral movement of said elongated saw blade, wherein said saw is configured so that said guide, when encountering a force imparted by said article during cutting while said guide is in said active position, is capable of moving from said active position to permit continued cutting of said article after said article is contacted by said guide during cutting, wherein the guide includes a blade limiting assembly for limiting lateral movement of the elongated saw blade when the guide is in said active position, the blade limiting assembly surrounding the elongated saw blade at a position spaced from the housing when the guide is in said active position, wherein the blade limiting assembly includes first and second opposing members that are spaced to a lateral spacing distance greater than a width of the blade, wherein the guide defines a clearance between the guide and the elongated saw blade, the clearance having a height greater than a height of the elongated saw blade, the saw being configured so that during cutting at least a portion of the article being cut can be accommodated within the clearance without the article being cut contacting the guide.

A guide for guiding an elongated saw blade of a saw having a major body and the elongated saw blade extending from the major body, said guide comprising:
- a blade limiting assembly having a pair of opposing surfaces for limiting lateral movement of said elongated saw blade;
- wherein said guide is configured to be mounted to a body of a saw;
- and
- wherein said guide is further configured so that said guide can be moved from an active position wherein said blade limiting assembly surrounds said elongated saw blade to limit lateral movement of said elongated saw blade, wherein the blade limiting assembly is adapted for limiting lateral movement of the elongated saw blade when the guide is in said active position, the blade limiting assembly being adapted to surround the elongated saw blade at a position spaced from the major body when the guide is in said active position, wherein the guide is adapted to define a clearance between the guide and the elongated saw blade, the guide being adapted to include a first arm and a second arm extending forwardly from the major body and delimiting the clearance, the guide being adapted so that the first arm and the second arm are spaced apart from one another in a manner that that the first arm and the second arm are disposed on opposite sides of a vertically extending plane extending coextensively with and encompassing the saw blade the guide being adapted so that the clearance has a height greater than a height of the elongated saw blade, the guide being configured so that during cutting at least a portion of the article being cut can be accommodated within the clearance without an article being cut contacting the guide.
