TABLE SAW WITH DROPPING BLADE
First Claim
1. A table saw, comprising:
- a latch hold mechanism;
a swing arm movable along a swing arm path between a first swing arm position adjacent the latch hold mechanism and a second swing arm position spaced apart from the latch hold mechanism;
a latch movable between a first latch position whereat the swing arm is maintained at the first swing arm position and a second latch position whereat the swing arm is not maintained at the first swing arm position;
an actuating device configured to transfer a force to the swing arm when the swing arm is maintained at the first swing arm position resulting in a bias on the latch in a direction toward the second latch position; and
a control system configured to control the actuating device to transfer a force to the swing arm when the swing arm is maintained at the first swing arm position sufficient to move the latch from the first latch position to the second latch position.

Abstract
A power tool in one embodiment is a table saw which includes a latch hold mechanism, a swing arm movable along a swing arm path between a first position adjacent the latch hold mechanism and a second position spaced apart from the latch hold mechanism, a latch movable between a first position whereat the swing arm is maintained at the first position and a second position whereat the swing arm is not maintained at the first position, an actuating device configured to transfer a force to the swing arm when the swing arm is maintained at the first position, and a control system configured to control the actuating device to transfer a force to the swing arm when the swing arm is maintained at the first position sufficient to move the latch from the first position to the second position.

8. A power tool comprising:
-
a work-piece support surface; a swing arm assembly movable along a swing path between a first swing arm position whereat a portion of a shaping device supported by the swing arm assembly extends above the work-piece support surface and a second swing arm position whereat the portion of the shaping device does not extend above the work-piece support surface; an actuator configured to force the swing arm assembly away from the first swing arm position and toward the second swing arm position; and a control system configured to actuate the actuator in response to a sensed condition. - View Dependent Claims (9, 10, 11, 12, 13, 14, 15, 16, 17, 18)

19. A table saw comprising:
-
a work-piece support surface; a frame supporting a carriage, the carriage movable along a first axis which intersects the work-piece support surface to a plurality of positions; a swing arm assembly mounted on the carriage and pivotable about a pivot axis extending generally parallel to the work-piece support surface, and pivotable along a plurality of swing paths, each of the plurality of swing paths associated with a respective on of the plurality of positions; and a stop pad mounted on the frame and configured to intersect each of the plurality of swing paths. - View Dependent Claims (20)
