Abstract
A reciprocating saw includes a housing, a motor positioned within the housing and configured to drive a reciprocating saw blade, and a shoe coupled to the housing. The shoe is configured to engage a workpiece. The reciprocating saw also includes a proximity sensor configured to detect the workpiece when engaged with the shoe. The proximity sensor is positioned on a forward end of the housing in a facing relation with the workpiece. In response to the proximity sensor detecting formation of a gap between the shoe and the workpiece, the proximity sensor is operable to deactivate the motor.
Claims11
A reciprocating saw comprising:
- a housing;
- a motor positioned within the housing and configured to drive a reciprocating saw blade;
- a trigger configured to selectively activate the motor;
- a shoe coupled to the housing and including a workpiece contact surface at a distal end thereof configured to engage a workpiece during a workpiece cutting operation;
- a workpiece detection system configured to detect rearward movement of the housing away from the workpiece;
- and
- a controller in communication with the workpiece detection system, the motor, and the trigger;
- wherein, in response to the workpiece detection system detecting the rearward movement of the housing exceeding a predetermined value while the trigger is depressed, the controller is operable to deactivate the motor,
- wherein the shoe is moveable relative to the housing between a retracted position, in which the shoe is configured to engage the workpiece, and an extended position in which a gap is defined between the shoe and the workpiece, in response to rearward movement of the housing;
- and
- wherein the workpiece detection system further includes a switch operable to communicate to the controller to deactivate the motor in response to being actuated by movement of the shoe from the retracted position to the extended position.
A reciprocating saw comprising:

- a motor positioned within the housing and configured to drive a reciprocating saw blade;
- a trigger configured to selectively activate the motor;
- a shoe coupled to the housing and including a workpiece contact surface at a distal end thereof configured to engage a workpiece during a workpiece cutting operation;
- a workpiece detection system configured to detect rearward movement of the housing away from the workpiece and formation of a gap between the shoe and the workpiece, the workpiece detection system supported by the housing;
- and
- a controller in communication with the workpiece detection system, the motor, and the trigger;
- wherein, in response to the workpiece detection system detecting the rearward movement of the housing exceeding a predetermined value or formation of a gap while the trigger is depressed, the controller is operable to deactivate the motor;
- and
- wherein the shoe is moveable relative to the housing between a retracted position, in which the shoe is configured to engage the workpiece, and an extended position in which a gap is defined between the shoe and the workpiece.
