First Claim
Patent Images
1. A router for cutting workpieces with one or more router bits, the router comprising:
- an operative structure configured to support a router bit in a nominal operating position to cut workpieces;
a motor assembly coupled to rotate at least a portion of the operative structure; and
a safety system including a detection subsystem configured to detect one or more dangerous conditions between a person and a router bit supported by the operative structure, and a reaction subsystem configured to retract the router bit at least partially away from the nominal operating position if one or more dangerous conditions are detected by the detection subsystem.

Abstract
A router is described for cutting workpieces with router bits. The router includes a safety system configured to detect one or more dangerous conditions between a person and a router bit. The safety system includes a reaction subsystem configured to perform one or more predetermined actions in the event a dangerous condition is detected. In one embodiment, the safety system is configured to detect accidental contact between a person and the router bit, and then at least partially retract the router bit the person.

11. For use with a router adapted to rotationally drive a router bit, a method for minimizing injury from a router bit coupled to the router, the method comprising:
-
detecting accidental contact between a person and the router bit; and
at least partially retracting the router bit away from the person in the event accidental contact between the person and the router bit is detected. - View Dependent Claims (12, 14, 15)
