Abstract
A fastener driver includes a drive blade movable from a retracted position to a driven position for driving a fastener into a workpiece and a gas spring mechanism for driving the drive blade from the retracted position to the driven position. The gas spring mechanism includes a piston movable between a retracted position and a driven position. The fastener driver further includes a first return mechanism for moving the drive blade from the driven position toward the retracted position, and a second return mechanism for moving the piston from the driven position toward the retracted position.
Claims20
A fastener driver comprising:
- a drive blade movable from a retracted position to a driven position for driving a fastener into a workpiece;
- a gas spring mechanism for driving the drive blade from the retracted position to the driven position, the gas spring mechanism including a piston movable between a retracted position and a driven position;
- a first return mechanism for moving the drive blade from the driven position toward the retracted position;
- and
- a second return mechanism for moving the piston from the driven position toward the retracted position.
A method of operating a fastener driver, the method comprising:
- initiating a drive cycle;
- releasing a gas spring mechanism for driving a drive blade from a retracted position to a driven position, the gas spring mechanism including a piston moveable from a retracted position toward a driven position for driving the drive blade;
- moving the drive blade from the driven position toward the retracted position with a first return mechanism;
- and
- moving the piston from the driven position toward the retracted position with a second return mechanism simultaneously with movement of the drive blade toward the retracted position.
