  • Patent number: 9636812
    Abstract: A fastener driving apparatus includes a drive mechanism, a drive piston disposed with in a cylinder and operatively coupled to the drive mechanism, and an anvil coupled to the drive piston. The apparatus also preferably comprises a biasing element for temporarily holding the drive piston at BDC of the piston cylinder. The drive mechanism is capable of selectively applying force on the drive piston to move the drive piston away from BDC of the piston cylinder. When the drive mechanism engages the drive piston to move the drive piston away from BDC, a vacuum is generated in the cylinder, which vacuum, after the drive mechanism disengages the drive piston, acts on the drive piston to cause the piston to move toward BDC and the anvil to drive a fastener. A sealed air chamber on the side of the piston opposite the vacuum may assist in generating force.

  • Patent number: 8875969
    Abstract: A fastener driving apparatus for driving fasteners into a substrate. The fastener driving apparatus is a combination of a motor driven linear motion converter; a compression cylinder; an expansion cylinder and a valve arrangement. The linear motion converter converts a rotational motion of a motor to a linear motion of a compression piston within the compression cylinder causing a gas within the compression cylinder to be compressed. The compressed gas is communicated to the expansion cylinder through the valve arrangement wherein the compressed gas expands causing an anvil coupled to an expansion piston within the expansion cylinder to move axially. The axial movement of the anvil causes a fastener to be driven into the substrate. The fastener driving apparatus is an ergonomically designed portable hand held tool providing comfort to a user, meeting safety standards and performance efficiency requirements.

  • Patent number: 8763874
    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. An improved lifter design has modified lifting pins that reduce the side-forces on the driver. A pivotable latch acts as a safety device, by preventing the driver from making a full driving stroke at an improper time. An improved latch design has a more durable catching surface.

  • Patent number: 8418903
    Abstract: A refill for staples, which can not be removed from a cartridge unless all sheet-type connected staples in a stapler body are delivered. A refill for staples is installed in a detachable manner in a stapler body, and includes a refill body which holds the sheet-type connected staples, and a pressing member which presses the sheet-type connected staples. A delivery port delivering the sheet-type connected staples and a locking plate provided with a locking section which locks a locked section in the stapler body are formed in the refill body. When the sheet-type connected staples are pressed, the pressing member is engaged with the locking plate not to allow rotation of the locking plate, and, when the sheet-type connected staples are not pressed, the pressing member is disengaged from the locking plate to allow rotation of the locking plate. Thereby, the locking section of the locking plate can be removed from the locked section in the stapler body.

  • Patent number: 8387718
    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 fastener driving apparatus includes a power source, a control circuit, a motor, a first cylinder, a first piston, a linear motion converter, a second cylinder, a second piston, an anvil, a valve arrangement and at least one sensor. During a compression stroke, the first piston is configured to compress gas in a first cylinder to a predetermined pressure. At the predetermined pressure, the valve arrangement assumes an open position for communicating the compressed gas to the second cylinder, thereby causing the second piston to move linearly and enabling the anvil to drive the fastener into the workpiece. During a return stroke, at a predetermined position of the first piston in the first cylinder, the valve arrangement assumes the open position for communicating a vacuum created in the first cylinder to the second cylinder and thereby causing the second piston and the anvil to retract to their initial positions.
