Plural Tools Pivotal With Respect To Plural Handles Patents (Class 72/409.11)
  • Patent number: 11679519
    Abstract: A light-weight bolt cutter tool includes a pair of opposing pivotally mounted jaws, each made from a fiber-reinforced composite body jacketed by a blade having a hardened metal outer surface oriented to forcibly engage the other one of said jaws. Each jaw can have pair of indentations proving the jaw with an I-beam-type cross-sectional shape. The bolt cutter tool can be actuated by a pair of elongated, hollow fiber resin composite handles. Each handle can include an elastomeric damping plug to prevent debris entering the hollow handle and reduce material fatigue. A quick-deployment, quiver-style backpack can conveniently carry the colt cutters when not in use.

  • Publication number: 20140245807
    Abstract: The present invention discloses a crimping tool, which comprises a first rod, a second rod, a transmission unit and a crimping portion. The first rod includes a first rod body. The second rod includes a second rod body and an abutting element, and the second rod body includes a guiding groove. The transmission unit comprises a transmission unit body, an adjustable portion, a sliding element and a linking element, wherein the adjustable portion is disposed on one end of the transmission unit body, which is external to the second rod body. The crimping portion is connected with the transmission unit body. When the crimping tool is used, the adjustable portion can be adjusted and thus the crimping portion is moved, thereby changing the distance between the crimping portion and the abutting element.

  • Patent number: 8522830
    Abstract: A crimping device for securing a seal member onto overlapped end portions of a strap material includes at least a tool head, operating and stationary handles, two rows of crimping elements having at least a pair of shears and oppositely situated pair of jaws extended between the pair of shears. The crimping elements may be disposed in the tool head and connected with the handles so that at least one row of crimping elements crimps a seal while at least one row is idle when the handles move away from each other. In an embodiment, the handles can make an inward stroke only when a full jaw-closing outward crimping stroke is completed. At least one row of crimping elements crimps the seal with an inward movement of the handles while at least one previously actuated row of crimping elements is not involved in closing the seal.

  • Publication number: 20080134747
    Abstract: The tool reduces or stops the flow of liquid or gas through a conduit and includes a crimping section, comprised of a first and second crimping member pivotally engaged with each other, and a handle section, comprised of a first and second handle member pivotally connected to each other. Each crimping member has a blunt section extending partially along an edge thereof. The first and second handle members are connected to the first and second crimping members. The conduit is crimped by applying a force to the handle members causing the handle members and the crimping members to pivot in a direction opposite each other so that the blunt sections of crimping members crimp a conduit placed therebetween thereby reducing or stopping the flow of the liquid or gas flowing through the conduit. The tool may also hold objects and be locked via separate locking mechanisms.

    Abstract: A tool for the cutting or coining of metal, including two jaws connected to parallel links by two jaw joint bolts. Two handles are connected to each other by a handle bolt and are connected to respective jaws by two middle bolts. Each jaw joint bolt is provided with an eccentric bearing surface situated between two coaxial bearing surfaces. The distance and parallelism of the jaws can be adjusted by producing rotating of the eccentric bearing surface by rotating one or more of the jaw joint bolts. The angular motion of the jaws is synchronized by a cylindrical roller retained axially between the links, and guided in a slot formed by overlapped fingers of the jaws.
