  • Patent number: 10676037
    Abstract: A roof rack system has a clamping system comprised of handles, an actuator, and a pair of jaws. The jaws provide a universal clamping system that will attach to most roof rack cross bars with an easy-on/easy-off, quick-release actuator, such as a ratcheting mechanism or lever system, that will integrate with a wide variety of accessories. The preferred actuator includes a lever mechanism with a linkage between the trigger handle and the elongated handgrip. An adjustment knob is used to adjust the longitudinal distance of the distal end of the linkage from the back end of the handgrip. This system is easier to use, more versatile, and less expensive than conventional roof rack accessory systems.

  • Publication number: 20080072716
    Abstract: A tool structure composed of two pivotally connected handles and a tool head. The handle pivot shaft of the handles is spaced from the head pivot shaft of the tool head by a certain distance to form a double-lever structure for saving strength. A pin member is fitted through each handle in parallel to the handle pivot shaft, whereby the pin members can be forced to axially move within the handles. Each pin member has a large diameter section and a small diameter section. When replacing the tool head, a user only needs to press the pin members of the handles with a hand. At this time, the large diameter sections of the pin members are detached from the insertion notches of the tool head to easily replace the tool head with another tool head with different usage. The replacement can be completed without using any tool. Therefore, the tool head can be quickly assembled with the handles.

  • Patent number: 7216523
    Abstract: The invention relates to a pair of pressing jaws for hydraulic or electric pressing tools for pressing fittings onto pipes or for the press connection of electric cables, the two pressing jaws being disposed for rotation about a common axis and each pressing jaw forming a bearing eye for this purpose. In order to configure a pair of pressing jaws of the type in question in a more functionally advantageous manner, it is proposed that each pressing jaw forms two bearing eyes with coaxial bearing openings, and the bearing eyes are disposed in an interengaging manner in the assembled state.

  • Patent number: 7156004
    Abstract: An adjustable wrench for gripping and rotation of a generally cylindrical canister, such as an oil filter canister, includes handles which are pivotally connected to each other for rotation about a first axis. Each handle is also connected by an articulatable joint to a gripping jaw that may be positioned about the canister or body, to thereby alter the angle of the handles with respect to the jaws in order to enable use of the tool in confined spaces.

  • Patent number: 6748830
    Abstract: A pliers having a replaceable gripping member for pliers jaws in the form of a threaded cylinder received in a threaded bore with part of the threaded cylinder extending out of the jaw in which it is mounted to provide a gripping surface formed of a segment of the threaded cylinder. The mating jaw has a recess to receive the projecting segment. A method of renewing the gripping surface includes rotating the threaded member to expose a different portion of the threads in the projecting segment, after removal of damaged threads in the projecting segment by filing the cylinder, if necessary. A hexagonal recess is formed in the end of the cylinder to enable installation, renewal of the segment and replacement of the entire cylinder using an Allen wrench. For non-sparking applications, the pliers are formed of aluminum bronze and the gripping member is formed of beryllium copper.
