Abstract: A powered fastener driver including a housing defining a cylinder support portion, a drive unit support portion, and a handle portion that is spaced apart from the drive unit support portion. The powered fastener driver includes a cylinder, a piston movable within the cylinder from a top-dead-center (TDC) position to a bottom-dead-center (BDC) position, a driver blade attached to the piston for movement therewith along a driving axis from the TDC position toward the BDC position, a lifter operable to move the piston and driver blade, in unison, from the BDC position toward the TDC position, and a drive unit supported by the drive unit support portion and operably coupled to the lifter. The powered fastener driver further includes a user interface supported by the housing, and a printed circuit board positioned within the housing and positioned between the drive unit support portion and the handle portion.

Abstract: A fastener driver includes a housing, a cylinder supported by the housing, and a moveable piston positioned within the cylinder. A driver blade is attached to the piston and movable therewith between a top-dead-center position and a driven or bottom-dead-center position. The driver blade includes a body having a first side and an opposite, second side with the driving axis passing therebetween, a plurality of teeth extending from the first side of the body, and a plurality of projections extending from the second side of the body. The body and the projections are bisected by a common plane. The teeth extend at an oblique angle from the first side of the body relative to the common plane.

Abstract: A powered fastener driver including a housing, a cylinder, a piston movable within the cylinder from a TDC position to a BDC position, a driver blade 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 operable to move the piston and driver blade, in unison, from the BDC position toward the TDC position, a drive unit operably coupled to the lifter, and a printed circuit board (PCB) positioned within the housing. The PCB receives electrical current from the battery pack and includes power switches for commutating the motor. The PCB defines a length and a width, and a vibration attenuating damper is positioned between the housing and the printed circuit board. The damper is positioned along the length of the PCB and is configured to support the PCB within the housing.

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 lifter having a body and a drive pin coupled to the body. A roller is positioned on the drive pin and engages with a tooth of the driver blade when moving the driver blade from the bottom-dead-center position toward the top-dead-center position. The roller includes a first engagement section that receives an end portion of the tooth and a second engagement section. An engagement member engages the second engagement section for aligning the first engagement section of the roller with the end portion of the tooth to facilitate meshing between the end portion of the tooth and the roller.

Abstract: A powered fastener driver includes a housing, a cylinder supported by the housing, and a moveable piston positioned within and moveable along a driving axis of the cylinder. The piston includes a circumferential groove on an outer peripheral surface thereof. A driver blade is attached to the piston and moveable therewith between a top-dead-center (TDC) position and a driven or bottom-dead-center (BDC) position. A seal assembly is received in the circumferential groove. The seal assembly is configured to create a seal between the piston and the cylinder. The seal assembly includes a biasing member and a seal member positioned radially outwardly of the biasing member relative to the driving axis.

Abstract: A powered fastener driver includes a driver blade and a drive unit having an output shaft for providing torque to move the driver blade from the bottom-dead-center position toward the top-dead-center position. A rotary lifter is engageable with the driver blade and configured to receive torque from the output shaft of the drive unit in a first rotational direction for returning the driver blade from the bottom-dead-center position toward the top-dead-center position. A kickout arrangement is defined between the lifter and the output shaft and configured to permit limited movement of the lifter relative to the output shaft between a first position and a second position. The kickout arrangement having a curvilinear slot defined in the rotary lifter in which a portion of the output shaft is received. Movement of the rotary lifter from the first position toward the second position causes the slot to move relative to the output shaft, while the output shaft remains within the slot.

Abstract: A powered fastener driver including a housing, an inner frame positioned within the housing, and a workpiece contact assembly coupled to the housing and movable from an extended position to a retracted position in response to contact with a workpiece. The workpiece contact assembly includes a biasing element that biases the workpiece contact assembly into the extended position. The workpiece contact assembly is engageable with the inner frame in response to an applied force that moves the workpiece contact assembly beyond the retracted position.
