System and method for rapidly stopping a spinning table saw blade
First Claim
1. A system for stopping a spinning saw blade, comprising:
- a pin assembly disposed adjacent to a saw blade assembly for stopping the spinning saw blade, the pin assembly including a first end, the first end including a pointed tip for piercing the saw blade;
a receiving block disposed on a side of the saw blade opposing the pin assembly for receiving the tip of the pin assembly;
a driving assembly coupled to the pin assembly for driving the pin assembly into the spinning saw blade and into the receiving block; and
a sensing assembly coupled to at least one of the saw blade assembly and the driving assembly for sensing encroachment of a user'"'"'s hand in a pre-defined zone, wherein upon sensing a user'"'"'s hand the sensing assembly signals the driving assembly to stop the spinning saw blade by driving the pin assembly through the saw blade and into the receiving block.

Abstract
A system for stopping a spinning table saw blade is comprised of a pin assembly disposed adjacent to a saw blade assembly for stopping a spinning saw blade. A receiving block is disposed on a side of the saw blade opposing the pin assembly for receiving the tip of the pin assembly. A driving assembly is coupled to the pin assembly for driving the pin assembly into the spinning saw blade into the receiving block. Finally, a sensing assembly is coupled to at least one of the saw blade assembly and the driving assembly for sensing encroachment of a user'"'"'s hand in a pre-defined zone. In use, upon sensing a user'"'"'s hand the sensing assembly signals the driving assembly to stop the spinning saw blade by driving the pin assembly through the saw blade and into the receiving block.

20. A saw, comprising:
-
a pin assembly disposed adjacent to a saw blade assembly, the saw blade assembly being configured for receiving a saw blade, the pin assembly including a first end, the first end including a pointed tip for piercing the saw blade;
a receiving block disposed on a side of the saw blade opposing the pin assembly for receiving the tip of the pin assembly;
a driving assembly coupled to the pin assembly for driving the pin assembly into the saw blade and into the receiving block; and
a sensing assembly coupled to at least one of the saw blade assembly and the driving assembly for sensing encroachment of a user'"'"'s hand in a pre-defined zone, wherein upon sensing a user'"'"'s hand the sensing assembly signals the driving assembly to stop the saw blade by driving the tip of the pin assembly through the saw blade and into the receiving block.
