Patent number: 11400574Abstract: A fastener driver including a main housing, 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 cylinder housing containing a pressurized gas, and a piston movable relative to the cylinder housing and biased by the pressurized gas from a retracted position toward a driven position. The cylinder housing is displaceable along a longitudinal axis of the piston relative to the main housing and away from the drive blade, while the piston remains stationary relative to the main housing, to reduce the pressure of the pressurized gas within the cylinder housing.Type: GrantFiled: June 20, 2017Date of Patent: August 2, 2022Assignee: Techtronic Power Tools Technology LimitedInventor: Essam Namouz

Patent number: 11345008Abstract: A method of operating a fastener driver comprises initiating a fastener driving operation by moving a driver blade from a retracted position toward a driven position, and detecting that the driver blade has become jammed in an intermediate position between the retracted position and the driven position. The method further includes moving a latch from a locked position, in which a lifter assembly is maintained in an engaged position by the latch for moving the driver blade from the driven position toward the retracted position, to a released position, in which the lifter assembly is movable away from the driver blade. The method further includes driving a motor to rotate a lifter of the lifting assembly, thereby moving the lifter assembly away from the driver blade, then, returning the lifter assembly to the engaged position, and moving the latch from the released position to the locked position.Type: GrantFiled: April 9, 2020Date of Patent: May 31, 2022Assignee: Techtronic Cordless GPInventors: Edward Pomeroy, Zachary Scott, John Schnell, Essam Namouz

Patent number: 10759029Abstract: A powered fastener driver includes a cylinder and a drive piston within the cylinder being acted on by a driving force resulting from a pressure differential. The powered fastener further includes a drive blade coupled to the drive piston and operable to drive a fastener, and an adjustable valve for selectively introducing air from ambient atmosphere into the cylinder, thereby changing the pressure differential acting on the drive piston. By adopting a self-contained vacuum generating means as described above, the present invention does not rely on any external vacuum source and powered fastener driver can be used and carried with conveniently.Type: GrantFiled: September 15, 2016Date of Patent: September 1, 2020Assignee: TECHTRONIC POWER TOOLS TECHNOLOGY LIMITEDInventors: John Schnell, Edward A.

Patent number: 10744630Abstract: A fastener driver comprises a drive blade movable from a retracted position to an extended, 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 drive cylinder and a drive piston attached to the drive blade for movement therewith. The drive piston is acted on by a driving force resulting from a pressure differential created by the gas spring mechanism. The fastener driver also includes an adjustable valve for selectively limiting a flow of gas into the drive cylinder above the drive piston, or a flow of ambient air at atmospheric pressure from the drive cylinder beneath the drive piston, thereby changing the pressure differential acting on the drive piston, as the drive piston and the drive blade move from the retracted position to the extended position.Type: GrantFiled: November 9, 2017Date of Patent: August 18, 2020Assignee: TTI (MACAO COMMERCIAL OFFSHORE) LIMITEDInventors: Edward Pomeroy, Zachary Scott, John Schnell, Essam Namouz
