TABLE SAW WITH SWING ARM SUPPORT
First Claim
1. A table saw, comprising:
- a latch hold mechanism;
a swing arm pivotable about a pivot along a swing arm path between a first swing arm position and a second swing arm position;
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;
at least one swing path guide extending adjacent to the swing arm path;
at least one swing path tracker positioned to be in opposition to the at least one swing path guide along the swing arm path; 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 includes a table saw with a latch hold mechanism, a swing arm pivotable about a pivot along a swing arm path, a latch movable between a first latch position whereat the swing arm is maintained at a 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, at least one swing arm guide extending adjacent to the swing arm path, at least one swing arm support positioned to be in opposition to the at least one swing arm guide along the swing arm path, and a control system configured to control the actuating device to transfer a force to the swing arm sufficient to move the latch from the first latch position to the second latch position.

11. A power tool comprising:
-
a work piece support surface; a shaping device support shaft automatically retractable along a retraction path from a first shaft position to a second shaft position in response to a sensed condition, wherein the second shaft position is more distal to the work piece support surface than the first shaft position; a latch pin movable between a first latch pin position whereat the shaping device support shaft is maintained at the first shaft position and a second latch pin position whereat the shaping device support shaft is not maintained at the first shaft position; at least one retraction path guide extending adjacent to the retraction path; at least one retraction path tracker positioned to be in opposition to the at least one retraction path guide along the retraction path; and a control system configured to cause the actuator to generate a force causing the latch pin to move from the first latch pin position toward the second latch pin position in response to a sensed condition. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18, 19, 20)
