Abstract

A table saw guard assembly for guarding a blade on a table saw is provided. The table saw guard assembly includes a support structure and a hood assembly including at least one of a front curtain, first side curtain, second side curtain and top curtain, wherein each of said curtains are independently moveable and/or removable from the hood assembly. Furthermore, a table saw guard assembly is provided including a quick release mechanism for connecting the hood assembly to the support structure.

First claim

What is claimed is:

1. A table saw guard assembly for guarding a blade on a table saw, said guard assembly comprising:
a riving knife; and
a hood assembly mounted to said riving knife including a first side curtain and a second side curtain, wherein each of said first and second side curtains are independently movable relative to said riving knife, wherein said first and second side curtains include a plurality of apertures for providing a sight line therethrough.

2. The guard assembly of claim 1 , wherein said hood assembly further includes a quick-release mechanism for selectively engaging said hood assembly to said riving knife.

3. A table saw guard assembly for guarding a blade on a table saw, said guard assembly comprising:
a riving knife; and
a hood assembly mounted to said riving knife including a first side curtain and a second side curtain, wherein each of said first and second side curtains are independently movable relative to said riving knife, wherein said first and second side curtains include an aperture for providing a sight line therethrough, wherein said hood assembly further includes a quick-release mechanism for selectively engaging said riving knife,
wherein said quick-release mechanism includes a fixed tab and a push tab pivotally connected to a pivot pin, wherein said push tab includes a lock pin and said riving knife includes an aperture for receiving said lock pin.

4. The guard assembly of claim 1 , wherein said hood assembly further includes a locking mechanism adapted to selectively engage and secure said at least one of said first and second side curtains.

5. The guard assembly of claim 4 , wherein said locking assembly includes a screw and a wing nut.

6. The guard assembly of claim 1 , wherein said first and second side curtains independently move in response to a force applied by a workpiece.

7. The guard assembly of claim 4 , wherein said first and second side curtains are moveable in accordance with said engagement of said locking mechanism.

8. The guard assembly of claim 1 , wherein said first side curtain includes a first coupler, and said second curtain includes a second coupler adapted to engage said first coupler thereby connecting said first and second side curtains.

9. A table saw guard assembly for guarding a blade on a table saw, said guard assembly comprising:
a riving knife; and
a hood assembly mounted to said riving knife including a first side curtain and a second side curtain, wherein each of said first and second side curtains are independently movable relative to said riving knife, wherein said first and second side curtains include an aperture for providing a sight line therethrough,
wherein said first side curtain includes a first coupler, and said second curtain includes a second coupler adapted to engage said first coupler thereby connecting said first and second side curtains,
wherein said first coupler includes a female snap-fit connector and said second coupler includes a male snap-fit connector adapted to selectively interconnect with the first coupler providing for codependent movement of said first and second side curtains.

10. The guard assembly of claim 1 , wherein each of said first and second side curtains are independently removable from said hood assembly.

11. A table saw guard assembly for guarding a blade on a table saw, said guard assembly comprising:
a support structure; and
a hood assembly mounted to said support structure including a first side curtain and a second side curtain, wherein each of said first and second side curtains are independently movable relative to said support structure, wherein said first and second side curtains include an aperture for providing a sight line therethrough, wherein said hood assembly further includes a quick-release mechanism for selectively engaging said support structure, wherein said quick-release mechanism includes a fixed tab and a push tab pivotally connected to a pivot pin, wherein said push tab includes a lock pin and said support structure includes an aperture for receiving said lock pin.

12. A table saw guard assembly for guarding a blade on a table saw, said guard assembly comprising:
a support structure; and
a hood assembly mounted to said support structure including a first side curtain and a second side curtain, wherein each of said first and second side curtains are independently movable relative to said support structure, wherein said first and second side curtains include an aperture for providing a sight line therethrough, wherein said hood assembly further includes a quick-release mechanism for selectively engaging said support structure, wherein said quick-release mechanism includes a fixed tab and a push tab pivotally connected to a pivot pin wherein said first side curtain includes a first coupler, and said second curtain includes a second coupler adapted to engage said first coupler thereby connecting said first and second side curtains, wherein said first coupler includes a female snap-fit connector and said second coupler includes a male snap-fit connector adapted to selectively interconnect with the first coupler providing for codependent movement of said first and second side curtains.
