  • Patent number: 9687968
    Abstract: A wrench-type tool that utilizes a plurality of engagement features to efficiently transfer torque to a fastener in order to rotate said fastener. The wrench-type tool includes a wrench-type torque-tool body. The wrench-type torque-tool body is the physical structure used to apply a torque force onto the fastener and includes a plurality of internal sidewalls and a plurality of engagement teeth. The plurality of internal sidewalls is radially distributed about a pivot axis of the wrench-type torque-tool body. Each of the plurality of engagement teeth is adjacently connected to a corresponding sidewall from the plurality of internals sidewalls in order to directly engage the sidewalls of the fastener. To increase the total contact surface with the fastener, a prismatic altitude for each of the plurality of engagement teeth is aligned parallel to the pivot axis. Furthermore, each of the plurality of engagement teeth is oriented towards the pivot axis.

    Abstract: An improved open end wrench having wrench heads at both ends of a shank whereon both wrench heads have arcuate surfaces and backup jaws coplanar with a common torqueing jaw whereby the torqueing jaw is a machined surface of the wrench shank that extends into the wrench heads and is terminated at reliefs at a depth less than half the thickness of the shank, at the intersection of the arcuate surfaces and said torqueing jaw, therein, when excessive torque is applied the relief tends to close whereby the backup jaw and torqueing jaw become nonplanar to each other, therefore wedging the polygonal fastener being worked.

  • Patent number: 8459153
    Abstract: A wrench including an inward opening that has a multi-point configuration for partially-surrounding engagement in a torque-transmitting manner on a polygonal profile of a nut or a bolt head, a radial jaw opening being associated with the inward opening and at least two corners of the multi-point configuration each having a stop for a portion of an end face of the polygonal profile. In order to extend the range of use of the wrench, the jaw opening has oppositely-disposed jaw cheeks as the opening of an open-end wrench for torque-transmitting engagement on the polygonal profile, the jaw cheeks extending over the corners of the multi-point configuration on only one wide face (of the wrench).

  • Patent number: 8443701
    Abstract: An open wrench includes a handle which is flat relative to a horizontal plane and a driving head is connected to the head. The driving head has a clamping opening with an opening communicating therewith. The driving head has two flat portions located on top and bottom of the driving head respectively and the flat portions each have an outer face, an inner face and a recess, all of which are located around the clamping opening and arranged in U shape. The inner face is located close to the clamping opening and the outer face is located close to the inner face. The outer face is raised, relative to the horizontal plane, from the mediate portion thereof and toward two ends of the outer face so as to define an inclined angle between the outer face and the horizontal plane.

  • Patent number: 8413551
    Abstract: An open-end wrench includes a jaw portion having two engaging portions and an opening between the engaging portions. Each engaging portion includes a driving face having a tip. A corner is formed between a bottom end of the opening and each driving face. A first length is defined between the bottom end in a direction perpendicular to an imaginary line passing through the tips. A spacing between the tips is larger than 0.95 times the first length and smaller than 1.05 times the first length. Two corners of a fastener received in the opening are located on the imaginary line and flush with the tips. Each engaging portion has a width at an associated corner in a direction perpendicular to an associated driving face. The width is the maximum distance from each driving face to an outer surface of the associated engaging portion. The width is larger than 0.2975 times a width between two parallel sides of the fastener and smaller than 0.4025 times the width of the fastener.
