Abstract:
Elevation mechanisms for table saws and anti-backdrive mechanisms for use in elevation mechanisms for table saws are disclosed. The anti-backdrive mechanisms typically include three sub-assemblies: an input assembly, an output assembly, and a fixed assembly. The anti-backdrive mechanisms prevent a torque related to the output assembly from changing the blade elevation. For example, the weight of the blade and the structure supporting the blade is prevented from backdriving the elevation mechanism and allowing the blade to drop.

Claim (Index 1):
A table saw comprising:\n a table defining a work surface; a substantially planar, circular blade configured to extend at least partially above the work surface; a blade support structure configured to support the blade; a motor to spin the blade; and an elevation system to change the elevation of the blade and blade support structure relative to the work surface, where the elevation system includes a handwheel adapted to be turned by a user to change the elevation of the blade and blade support structure relative to the work surface; and a cable spool operatively associated with the handwheel to turn as the handwheel turns; and a cable assembly comprising a first cable section with two ends and a second cable section with two ends, where one end of each section is operatively connected to the cable spool and the other end of each section is operatively connected to the blade support structure, and where the cable sections wind and unwind on the cable spool as the cable spool turns; where the winding and unwinding of either the first or second cable section raises or lowers the blade.
