  • Patent number: 8991675
    Abstract: A dynamic clutch apparatus for an electrical nail gun includes a pair of symmetric direct stroke apertures formed on a gun body support; a firing pin set slidably installed on a side of the gun body support; a guiding base movably installed inside the gun body support; a pair of symmetric oblique stroke apertures formed on the guiding base. Aperture walls of the oblique and direct stroke apertures encircle and form an interconnected through aperture. Two pivot bearings are slidably installed inside the through aperture. A flywheel for accumulating kinetic energy is installed between the pivot bearings coaxially. An electromagnetic driver drives the guiding base to move, causing the through aperture to restrict the pivot bearings and the flywheel to move and press the firing pin set. Then, the firing pin set passes nail-percussion kinetic energy along a nail-percussion axial direction.

  • 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.

  • Publication number: 20130233903
    Abstract: Compression return springs can be mounted on rails between the driver and an impact absorber. The springs include a plurality of wires twisted together to form a multi-stranded twisted wire member, which forms the coils of the spring. The springs can have an inner diameter that resists movement of the coils along the rails when the spring is at its free length, but has a mounted inner diameter that freely allows such movement. The coil-to-coil pitch of the spring can vary along its length. A motor initially rotates the flywheel without engaging the driver. The driver then contacts the rotating flywheel to propel the driver, which compresses the return springs against the impact absorbers as the driver travels from the returned position to the extended position.

  • Publication number: 20120037684
    Abstract: A stapler selectively uses enhanced leverage to break a glue bond of a staple to separate the staple from a rack of staples in the stapler. The staple does not press a working surface during this operating stage. The extra leverage stage occurs through a minority of total handle travel, preferably via a pivoting lever linked to the striker at one end and the opposite end traversing between inner spaced apart ribs underneath the handle. A remaining non-leveraged handle travel stage ejects a staple out from the stapler body against a working surface. A track supports staples from an underside of the top of the staples. The track includes an outward extending bottom support for at least one staple on the track to prevent rotation of a short rack of staples.

  • Patent number: 8011441
    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.
