  • Patent number: 11241776
    Abstract: A portable linear fastener driving tool is provided that drive staples, nails, or other linearly driven fasteners. The tool uses a gas spring principle, in which a cylinder filled with compressed gas is used to quickly force a piston through a driving stroke movement, while a driver also drives a fastener into a workpiece. The piston/driver is then moved back to its starting position by use of a rotary-to-linear lifter, and the piston again compresses the gas above the piston, thereby preparing the tool for another driving stroke. The driver has protrusions along its edges that contact the lifter, which lifts the driver during a return stroke. A pivotable latch is controlled to move into either an interfering position or a non-interfering position with respect to the driver protrusions, and acts as a safety device, by preventing the driver from making a full driving stroke at an improper time.

    Abstract: A fastening tool is provided, wherein a relief valve piston (65) is arranged that blocks an air passage from an air plug (58) to an accumulator chamber (50) and that opens/closes a flow path of a discharge port of compressed air from the accumulator chamber (50) to the atmosphere. When a state in which a trigger lever (21) is pulled while a push lever is released continues for a prescribed time or longer, a portion of the compressed air in the accumulator chamber (50) is released to the outside from the discharge port to notify the operator that the trigger lever (21) has not returned. If the trigger lever (21) is not returned even after the notification, the compressed air in the accumulator chamber (50) is discharged to the atmosphere at once and an air passage from an air plug (58) to the accumulator chamber (50) is blocked.

  • Patent number: 11224959
    Abstract: A driving tool for driving fasteners into a workpiece and operable in a single shot mode and in a bump fire mode, wherein the driving tool includes a resetting assembly including a control volume, wherein the resetting assembly is activatable in the bump fire mode by movement of a piston during each fastener driving-in cycle so that a fluid path from a cylinder to the control volume facilitates an increase in pressure to the control volume, and wherein responsive to a pressure in the control volume falling below a limit value due to venting of air from the control volume, the resetting assembly is operable to prevent actuation of a workpiece contact element from causing a valve piston to move to an actuation position until a trigger lever is released.

  • Patent number: 11179158
    Abstract: A handle assembly and a surgical stapler including the handle assembly is provided, wherein the handle assembly includes a first handle and a second handle. A first limit portion and a second limit portion are provided on one end of the first handle and one end of the second handle, respectively. The first limit portion is on a proximal end side of the second limit portion. As the first handle is at its initial position, the first limit portion abuts the second limit portion to prevent the first handle from rotation in a second direction. In an invalid state, the first handle can still be squeezed; meanwhile, the first and the second limit portions limit the initial angular position of the first handle and the initial position of the second handle. When the first handle is not rotated, the second handle cannot be rotated and the stapler cannot be fired.

  • Patent number: 11090794
    Abstract: A self-adjusting cable guide can be coupled to a nosepiece assembly having a contact end and can be movable between an extended guide position and a retracted guide position relative to the contact end of the nosepiece assembly. A contact trip arm can be adjacent the cable guide and can have a distal end positioned to contact a cable received within a guide recess of the cable guide. The contact trip arm can be movable between an extended arm position corresponding to an inactive state of the tool and a retracted arm position corresponding to an active state of the tool. In addition, the cable guide can have a non-aligned orientation, in which cooperating misalignment stop surfaces can engage each other to stop movement of the self-adjusting cable guide toward the retracted guide position and an aligned orientation in which movement into the retracted guide position is permitted.

  • Patent number: 11065749
    Abstract: A pneumatic fastener driver is operable in a single sequential mode and a bump-fire mode. The pneumatic fastener driver includes a housing, a nosepiece extending from the housing from which fasteners are ejected, and a trigger moveable between a default position, in which a drive cycle is inhibited from initiating, and a depressed position, in which the drive cycle is permitted to be initiated. The pneumatic fastener driver further includes a contact arm movable relative to the nosepiece between an extended position and a retracted position, and a timeout mechanism operable in the bump-fire mode to inhibit the drive cycle from being initiated in response to inactivity of the contact arm over a preset time interval that begins once the trigger is actuated from the default position to the depressed position.

  • Patent number: 10888983
    Abstract: A powered nailer includes a power source including a driving element reciprocating within a cylinder between a prefiring position and a fastener driving position, the latter occurring when the driving element engages a bumper disposed at the bottom of the cylinder. A reciprocating valve element defines a combustion chamber in fluid communication with the cylinder, and is configured for receiving a dose of fuel and air prior to a user-generated ignition. A return chamber at least partially surrounds the cylinder and is in fluid communication with the cylinder, being configured for receiving a supply of pressurized air generated by the driving element as it moves from the prefiring position to the fastener driving position, the pressurized air acting on an underside of the driving element for returning it to the pre-firing position.
