Patent ID: 8534527

Claim:
A driving tool comprising: a frame defining a rotational axis and a driver axis; a motor coupled to the frame; a flywheel rotatably driven by the motor about the rotational axis; a rail coupled to the frame; a driver that is slidably mounted on the rail and movable along the rail between a returned position and an extended position; and a follower coupled to the frame and movable between a first position, in which the follower drives the driver into engagement with the flywheel when the driver is in the returned position to transfer energy from the flywheel to the driver to propel the driver on the rail relative to the flywheel along the driver axis toward the extended position, and a second position in which the follower, the driver and the flywheel are not engaged to one another; wherein the rail is configured to guide the driver when the driver is moved from the extended position to the returned position wherein a return spring is mounted on the rail, the return spring biasing the driver toward the returned position.
