  • Publication number: 20110113565
    Abstract: The present invention is an attachment device that can be placed upon a tool, preferably a cable cutting tool, which replaces a hammer in an electrician's tool supply or eliminating the need for an electrician to carry a hammer around a job site. The attachable hammer head is made from a solid piece of metal in which there is flat hammer head with a set of flanges on the opposite side of the hammer head in which there is a channel between the flanges and one or more threaded holes within the flanges. The back blade of the wire cutters is placed within the channel and a set screw is in the one or more threaded holes. The set screws are tightened onto the blade affixing the solid mass of metal onto a wire cutter and allowing the user to efficiently use one tool for hammering wire cutting. The attachable hammer head is able to be removed as needed by the user.

  • Publication number: 20100139458
    Abstract: A coupling for an elongated handle and a tool head is provided. The coupling may be positioned at the handle upper end after the handle upper end has passed through the tool head eye. The coupling is a frustoconical shape which engages the tool head in a manner of a slip eye coupling. However, because the lower end of the handle does not pass through the tool head eye, the lower end of the handle, i.e., the grip, may have any shape. Thus, the present invention allows for use of a slip eye coupling while also allowing the handle grip to be of any shape.

  • Patent number: 7665390
    Abstract: A striking tool is disclosed that comprises a generally U-shaped or V-shaped handle constructed of a substantially resilient material and having a head fixed at one end thereof. A second end of the handle has a hand grip or gripping region adapted to be grasped by a human hand. The second end of the U-shaped or V-shaped handle includes a flange, or stop member, to inhibit the handle from slipping out of the grasping hand. The hand grip may include a lip at a lower end thereof, such that a pinky finger of the hand may be comfortably placed on either side of the lip while the hand grasps the hand grip. The resilient material construction of the handle permits a first end of the handle to flex slightly towards and away from the second end of the handle. Accordingly, during use, the striking tool provides a damped recoil and improved striking action, imparting less shock to the hand, wrist, elbow, shoulder, and other parts of the body, as compared to a conventional striking tool.

    Abstract: A pulling tool for pulling nails, screws, rivets, pegs, or other protrusions includes a jaw which may be opened to receive the head of the protrusion. The jaw is then at least partially closed against the protrusion, and when the handle of the tool is pulled, the jaw is both urged shut and also away from the surface from which the protrusion extends. Thus, as the protrusion is pulled, its shaft is also more tightly grasped, which helps to pull the protrusion from the surface without stripping off its head/cap. The pulling tool can be provided as a part of a hammer, crowbar, or other conventional tool.

    Abstract: An apparatus for locking the head of a hand tool to the handle of the tool. The apparatus generally includes a tapered handle with one or more groove cut into the handle at the tool end of the handle. The grooves are then filled with a compressible material. The head of the tool (such as a pick axe, a hammer, an axe, etc.) is then placed over handle and moved over the grooves to the end. The compressible material will lock the head into place, fixing a longstanding problem with hand tools of the heads coming loose.

  • Patent number: 7134363
    Abstract: Deadblow hammers capable of minimizing or eliminating recoils when the hammers impact their targets are discussed which have easy access anti-recoil chambers and which have open sockets for receiving handles that extend the length of the hammerhead body. These hammers incorporate filler materials, which function to negate the effects of the hammer recoils, with improved filling port(s) for filling the filler materials. Golf clubs with anti-recoil chamber and insert elements are also discussed.

  • Patent number: 7096761
    Abstract: An ergonomic handle for a hand tool includes a main portion extending in a longitudinal direction between a gripping portion and a tool head supporting portion opposite the gripping portion. Both the gripping portion and the tool head supporting portion are offset at an inclination in relation to the longitudinal direction of the main portion at a compound angle including a lateral angle and a vertical angle to ensure proper alignment while improving the line of sight to the tool head. The handle is suited for a hammer system in which removable fastening means secure the tool head to the handle to permit various adjustments to be made to the tool head. A tension member is also received through the handle under tension so that the handle is pre-stressed under compression for added strength.

  • Patent number: 7080576
    Abstract: A multi-accessory hammer is provided having an rapid release accessory change mechanism that includes a housing mounted to the butt end of a hammer and having an opening therein. A resilient means such as a spring is mounted within the housing, and an accessory locking device is mounted over the spring. One end of this locking device extends through the opening in the housing and is capable of rapidly hooking onto an accessory. The locking device also has a side arm extending along the exterior of housing and is capable of urging the locking device against the resilient means to allow unhooking of the accessory from the locking device.

  • Patent number: 7080577
    Abstract: A marker tag for tree trunks is provided with a flat element bearing indicia adapted to clip onto an applicator hammer. A nail extends perpendicularly through the flat element and is able to slide in a passage opening in the flat element preferably subject to the action of a clamping force and only able to be slid on application of a force. After driving the nail provided with the marker tag into a living tree trunk the trunk continues to increase in diameter and accordingly pushes the marker tag along the nail so that after a certain number of years it is stripped off and drops to the ground.

  • Patent number: 7066052
    Abstract: A hammer includes a handle, a hammer body mounted on an end of the handle and having a side formed with a combination bar inserted into the handle, and a protective jacket integrally formed on the handle to encompass a periphery of the combination bar and a mediate portion of the hammer body entirely. Thus, the protective jacket of the handle encompasses the periphery of the combination bar and the mediate portion of the hammer body entirely, so that the handle and the hammer body are combined with each other rigidly and stably, thereby enhancing the combination strength of the hammer.

  • Patent number: 6986504
    Abstract: A pulling tool for pulling nails, screws, rivets, pegs, or other protrusions includes a jaw which may be opened to receive the head of the protrusion. The jaw is then at least partially closed against the protrusion, and when the handle of the tool is pulled, the jaw is both urged shut and also away from the surface from which the protrusion extends. Thus, as the protrusion is pulled, its shaft is also more tightly grasped, which helps to pull the protrusion from the surface without stripping off its head/cap. The pulling tool can be provided as a part of a hammer, crowbar, or other conventional tool.

  • Patent number: 6983674
    Abstract: An impact device has a handle attached to an impact head. A weight is reciprocatably mounted on a guideway on the impact head. The weight can move along the guideway between a first position and a second position in response to motion of the head. A yielding member such as a spring or elastomeric element can be mounted at the impact head. The weight can recoil against the yielding member in response to motion of the head. The impact head can hit an object in such a manner as to move the weight in a straight line from the first position to the second position.

  • Patent number: 6976406
    Abstract: The present invention provides a hand-held striking tool that has a head disposed forward of the centerline of a handle. The hand-held striking tool of the present invention may further include a flange positioned beneath the head of the tool, the flange functioning as a second area of contact so that the effect of overstrike may be controlled. The present invention also provides a hand-held striking tool that isolates the striking head of the tool from the handle such that the effect of vibrations caused by using the tool are reduced.
