Abstract
The present invention is directed to a blade guard assembly capable of allowing increased capacity for saws, such as radial arm saw, miter saws, and the like. The assembly includes a U-shaped guard and a pivot pin for allowing the guard to obtain a plurality of positions including a guarding orientation and a cutting orientation. The guard may pivot so as to allow a larger dimension workpiece to be cut without exposing the saw blade unnecessarily. Additionally, a biasing device may be included for generally forcing the guard into a guarding orientation.
Claims18
A saw, comprising:
- a base;
- a table rotatably attached to the base;
- a saw assembly rotatably attached to the table via hinge, the saw assembly being pivotable about a first axis and along a first direction between an upper position away from the table and a lower position engaging a workpiece disposed on the table, the saw assembly comprising a support arm pivotably attached to the table via the hinge, a first guard attached to the support arm for at least partially covering an upper portion of a saw blade having a rotational axis substantially parallel to the first axis;
- a second guard pivotally attached to the support arm for at least partially covering a rear portion of the saw blade, the second guard being pivotally attached to the support arm at a location outside of a periphery of the saw blade and between the hinge and the rotational axis of the blade, the second guard having two side walls and a bottom portion, the second guard being pivotable in a second direction opposite to the first direction when the saw assembly is moved to the lower position or when the second guard contacts the workpiece so that the saw blade extends through the bottom portion.
