  • Patent number: 10820936
    Abstract: Disclosed is a universal pedicle screw removal tool comprising a tapered shaft having an “L” shaped tip on one end and a generally square head on an opposite end. A lower section leads to a tapered section which is connected to a handle. The handle may include a set of serrations to provide increased grip. The handle is connected to the head. The tip is sized to engage the channel of a tuliped pedicle screw while the head is sized to engage a ratchet or other torque producing tool. In an alternate embodiment, the tip is “T” shaped. In another alternate embodiment, the handle section includes opposing members extending from the shaft to form a “T” shaped handle. In use, the tip is inserted into the channel of a tuliped pedicle screw while the shaft is rotated to unscrew the pedicle screw from a patient's bone.

  • Patent number: 10377030
    Abstract: A tool handle for holding multiple tools of different sizes during use. A wedge and body which, when placed together, creates a handle with a generally cylindrical shape and internal cavities for retaining hexagonal wrenches. A sliding wedge holds the hexagonal wrench and itself into place. A plurality of slots that allow each size tool to be indexed to the underside of the sliding member/wedge. There are two grouping arrangement of tools within the handle: a large group and a small group facing the opposite direction. The purpose for the two groups is to optimize the function of the wedge. If all of the tools were oriented in the same main slot then the smallest tools would not protrude from the end of the handle/body in a screwdriver mode to facilitate good function. Therefore the two groupings are arranged back to back to stabilize the tools laterally.

  • Patent number: 8887599
    Abstract: A socket extension and related methods of utilizing a socket extension that improves upon conventional designs through the use of a shaped body allowing the socket extension to be manipulated with an appropriate tool at any point along the shaped body. Through the use of the shaped body, a user is provided multiple engagement points such that interference due to the proximity of other structures or other accessibility issues can be overcome. In addition, the shaped body presents the opportunity to utilize a plurality of tools on the same socket extension when additional force/torque is necessary to loosen and/or tighten a bolt.

  • Patent number: 8826781
    Abstract: A screwdriver includes a grip defining an accommodation chamber, an inner tube with interference holes mounted in the accommodation chamber, a rod member movable in and out of the inner tube and having interference grooves corresponding to the interference holes and a neck and carrying a latching member, an operating device set, which includes an operating member rotatably mounted at the front side of the grip, interference members and an actuation member having a pressure wall for holding down the interference members, a first elastic member, a ring cap having an axial hole and a stop wall around the axial hole for stopping the latching member, and a second elastic member. Thus, the screwdriver is operable by rotating the operating member and effectively prevents the rod member from being ejected out of the grip.

  • Patent number: 8820196
    Abstract: A safety block that includes a drive member on a lower face for attaching a socket or other tooling for applying torque to a screw, bolt, nut or other fastener. The safety block has a pair of drive pockets in an upper face of the block on opposed sides of a drive axis that passes through the drive member. The pair of drive pockets are sized and arranged to accept a square-shaped driver of a separately-provided wrench or breaker bar, to permit applying opposed, co-directional torque upon the socket or other tooling, thereby obviating the need to use a breaker bar or similar makeshift arrangement for breaking loose nuts and bolts in the field or on machinery.

  • Patent number: 8806994
    Abstract: A tool for manipulating the hand brake controls on a railroad car by a user standing on the ground generally comprises an elongate handle and a split collar swivelly attached to the distal end of the handle. The collar includes split for passage of the rim of a brake wheel, and a central bore for retaining the rim while the user turns the brake wheel with the collar bearing against a spoke. A cavity in distal end of handle is adapted for engaging the free end of a brake release handle for moving it to release the brakes. Each side of the collar includes a concave portion adapted for engaging a spoke of the brake wheel for turning the wheel for final tightening of the brakes. Preferably, the handle includes a plurality of telescopingly coupled sections and locks for locking the handle at an extended position.

  • Patent number: 8757033
    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: 8739662
    Abstract: A telescopic handle for a hand tool includes a main shank connected to a tool head at a distal end and insertable into an outer sleeve which a user grips. The main shank has a plurality of axially spaced retained regions such that a radially movable retaining member is engageable with a selected one of the retained regions. A key-and-keyway mechanism is disposed to guide axial movement of the outer sleeve and to guard against rotation of the outer sleeve relative to the main shank so as to permit delivery of an appropriate torque to the main shank. An operating member is disposed on and movable axially relative to the outer sleeve to radially move the retaining member.

  • Patent number: 8733215
    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.
