Abstract: A powered fastener driver includes a housing defining cylinder support portion, a drive unit support portion, and a handle portion that is spaced apart from the drive unit support portion. The handle portion defines a handle axis. A piston is movable within a cylinder from a TDC position to a driven or BDC position. A driver blade is attached to the piston for movement therewith along a driving axis from the TDC position toward the BDC position for driving a fastener into a workpiece. A lifter is operable to move the piston and driver blade, in unison, from the BDC position toward the TDC position. A drive unit is supported by the drive unit support portion and operably coupled to the lifter. The drive unit includes a motor having first output shaft that extends along a motor axis. The motor is positioned below the handle. The handle axis and the motor axis intersect the driving axis.

Abstract: A powered fastener driver includes a driver blade movable from a top-dead-center position to a bottom-dead-center position for driving a fastener into a workpiece, a drive unit for providing torque to move the driver blade toward the top-dead-center position, and a rotary lifter engageable with the driver blade. The rotary lifter having a body and a drive pin coupled to the body. A roller is rotatably coupled to the drive pin and includes a non-cylindrical outer peripheral surface defining a plurality of engagement sections. A tooth of the driver blade is configured to engage one of the engagement sections when moving the driver blade from the bottom-dead-center position toward the top-dead-center position.

Abstract: A fastener driver includes a housing, a cylinder supported by the housing, and a movable piston positioned within the cylinder. A driver blade is attached to the piston and movable therewith between a top-dead-center (TDC) position and a driven or bottom-dead-center (BDC) position. The driver blade includes a body portion extending along a longitudinal axis, and a tip portion configured to contact a fastener. The tip portion is bisected by a central axis that is parallel with the longitudinal axis such that the tip portion is laterally offset relative to the body portion.

Abstract: A power tool including a housing, a trigger disposed on an outside of the housing, the trigger including a magnet, a motor within the housing, the motor configured to produce a rotational output to a drive mechanism, a Hall effect sensor configured to sense a position of the trigger based on a proximity of the magnet to the Hall effect sensor, and an electronic controller connected to the Hall effect sensor. The electronic controller is configured to determine the position of the trigger based on a signal from the Hall effect sensor and control the drive mechanism based on the position of the trigger.

Abstract: A powered fastener driver includes a driver blade movable from a top-dead-center (TDC) position to a bottom-dead-center (BDC) position for driving a fastener into a workpiece and a drive unit for providing torque to move the driver blade from the BDC position toward the TDC position. A kickout arrangement is at least partially defined by an outer surface on one of a torque output member and a torque input member and an aperture formed in the other of the torque output member and the torque input member in which the outer surface is received. The kickout arrangement configured to permit limited rotation of the torque output member relative to the torque input member between a first position and a second position.

Abstract: A fastener driver includes a magazine configured to receive fasteners, a nosepiece including a fastener driving channel from which consecutive fasteners from the magazine are driven, and a workpiece contact element movable relative to the nosepiece between an extended position and a retracted position. A portion of the workpiece contact element is slidably positioned within the fastener driving channel. The portion of the workpiece contact element having an aperture extending therethrough in which the fasteners pass from the magazine through the aperture into the fastener driving channel of the nosepiece to be fired. The portion of the workpiece contact element further includes a guide assembly positioned thereon. The guide assembly configured to guide the fastener along the portion of the workpiece contact element within the fastener driving channel as the fastener is being fired into a workpiece.
