    Abstract: A tool extension for a socket wrench includes a jointed, articulated series of square-drive male/female adapter ends with intermediate couplers having hex ball-head and socket joints. Three such intermediate couplers together in one series allow for an overall 90-degrees of flex. Each coupler has a bell body over which a pliable control cover is stretched. Each hex ball head and socket joint is bridged over by a corresponding pliable control cover which then snaps over a retaining lip just under a neck.

  • Patent number: 8070377
    Abstract: A quick-release coupler includes a rod having first and second sections. The first section includes an end for coupling with a pneumatic tool. The second section extends from the other end of the first section. A sleeve is slideably mounted around the rod and includes an end for releasably coupling a bit. The sleeve includes an axial bore having larger and smaller sections. The larger section has polygonal cross sections corresponding to polygonal cross sections of the first section. A radial bore is formed in the sleeve and in communication with the smaller section. A ball is moveably received in the radial bore and moveably received in a recess of the second section of the rod to releasably engage the sleeve with the bit. A spring is mounted in the larger section of the sleeve for biasing the sleeve towards the other end of the rod.

  • Patent number: 8065938
    Abstract: A shaft has a driving end and a driven end. A plurality of driving adaptors with various handles are releasably connected to the shaft driving end. A plurality of driven adaptors with various tools for performing operations within a limited space work area, such as an inaccessible space, a confined space, or keyhole excavation, are releasably connected to the shaft driven end. The driving adaptors are positioned outside of the limited space work area. The driven adaptors are positioned within the limited space work area. The handle is manipulated at the shaft driving end to transmit selected rotational and translational movements through the shaft to the tool to perform operations in the limited space work area.

  • Publication number: 20110283841
    Abstract: A hand tool includes a tool head and a handle connected to the tool head. The tool head is adapted to drive a fastening member. The handle includes an external tube adapted to be held by a user, and an internal rod inserted into the external tube. One end of the internal rod is connected to the tool head. The external tube can be selectively moved relative to the internal rod between a first position and a second position. While in the first position, the external tube is securely engaged with the internal rod. While in the second position, the external tube is rotatable relative to the internal rod so that the user can regulate the external tube of the handle in the first position or the second position upon demands, thereby obtaining comfortable and power-saving operation.

  • Patent number: 8033200
    Abstract: A universal ratcheting tool provides improved handling of tools that are difficult to use on their own, specifically, hexagonal wrenches. The universal ratcheting tool includes a handle and a body with a ratcheting mechanism within the handle. The body includes a first aperture for receiving a tool, and the first aperture includes slots to accept a plurality of sizes of tools. The body also includes a second aperture where the tool extends out of the body. A retaining component is coupled with the body to retain the tool and a retaining tab is able to be used to open and close the retaining component. Once the tool is positioned and retained within the universal ratcheting tool, a user is able to easily install or remove an object such as a screw with the benefit of a comfortable handle and the ease of use of the ratcheting mechanism.

  • Patent number: 7975576
    Abstract: A low clearance drive system includes a low clearance socket and/or a low clearance male driver (50). The socket has a reduced depth drive receptacle and a reduced-depth output fastener receiving receptacle. Each of the male driver and the socket drive receptacle has an axial length (L3) or depth which is less than its nominal transverse width (w). The male driver may have a detent ball (55) adapted to be engaged in a detent recess in the female drive receptacle, such that the ball diameter is less than half the nominal transverse drive width and may be either equal to or less than the diameter of the detent recess.

  • Publication number: 20110132153
    Abstract: A torque driver includes a driver arm with a pivot mounting hole formed adjacent one end, a driver spindle mounting slot or sockets spaced from the pivot mounting hole providing multiple mounting positions for retaining the driver spindle, and a locking detent. A locking element engages the locking detent, a load applicator generates a selected load onto the locking element, and a handle is pivotally attached to the driver arm at the pivot mounting hole and has finger groove for applying a tightening force. The locking detent, the locking element and the load applicator cooperate to permit relative movement between the driver arm and the handle when the tightening force applied at the finger groove is at a pre-determined value.

  • Patent number: 7956711
    Abstract: Tool attachments and extensions handles may be removably connected to each other. In an example embodiment, a tool attachment is capable of being connected to an extension handle having an extension handle connector, which includes a first field emission structure. The tool attachment has a tool implement and a tool attachment connector, which includes a second field emission structure. The tool attachment connector is adapted to be mated to the extension handle connector with the second field emission structure in proximity to the first field emission structure such that the first and second field emission structures have a predetermined alignment with respect to one another. Each of the first and second field emission structures include multiple Field emission sources having positions and polarities relating to a predefined spatial force function that corresponds to the predetermined alignment of the first and second field emission structures within a field domain.
