  • Patent number: 9718179
    Abstract: A striking tool having an improved attachment mechanism to safely and securely attach the head of the tool to the tool handle. In one configuration, the attachment mechanism has a key at the upper end of the handle that is sized and configured to be received in and engage a cooperatively configured keyway on the lower side of the head. In another configuration, the attachment mechanism has a connecting element with an elongated body that extends through a tubular body portion at an upper section of the handle and into a passageway in the head. In yet another configuration, the striking tool has both attachment mechanisms. A striking member made out of harder material can be utilized for the striking portion of the head. The connecting element can connect to an aperture in the striking member. A side nail puller can be positioned on the outer surface of the handle.

  • Publication number: 20130247722
    Abstract: Disclosed is a nail-in anchor pin setting device that is used in conjunction with a hammer to set an anchor into a surface prior to driving the setting nail thereinto to expand the anchor. The device comprises an elongated, largely cylindrical device having an impact end and a driving end. The impact end receives driving loads from a hammer, while the driving end comprises an internal bore to accept the anchor pin therethrough. The driving end is placed against the collar of the anchor while the anchor pin is accepted through the device bore. The hammer end is driven against the collar to force the anchor into a wall surface substrate, whereafter the tool can be removed from the anchor to reveal the set anchor and exposed nail pin to be driven into the anchor for expansion and securement thereof.

    Abstract: The hammer system of an embodiment may allow a user to start driving a nail (e.g., into a board or the like) without having to hold the nail with their other, non-hammering hand. For example, the hammer system may accept and detachably couple to a nail. Once coupled, the hammer system may partially drive the nail, for example with a moderate strike and/or multiple taps, such that the nail is substantially secure and/or stable enough to accept subsequent driving strikes without the user having to hold the nail in place.

    Abstract: A hammer assembly having means for holding a nail includes a hammer and a nail holder. The nail holder is detachably mounted to the hammer to expose its one part or entirety outside an external surface of the hammer. When the nail holder is separated from the hammer, the nail holder can be used for holding a nail which is to be hit by the hammer. In this way, the user does not need to hold the nail by his or her hand to prevent the user's hand from any accidental hit of the hammer. Besides, when the nail holder is not needed, the user can mount it to the hammer. Therefore, the hammer assembly can be operated safely and stored conveniently.

    Abstract: This tested invention, for use with an unmodified hammer (402), is a simple attachment (31) whose fastener-receiving region (57), and fastener-holding apparatus (54), along with a magnetism and support extender (542), allow safe, one-handed starting of a wide range of size and types of fasteners (562), including nails, screws, tacks, and staples. With the attachment, a fastener can be easily started with the usual initial hammer swing and then driven to the desired depth by striking it with the hammer face in the conventional manner with an unbroken rhythm. The attaching mechanism (72) enables attaching to and detaching from a hammer with only one hand. Spacers (202), or tailor forming of the attachment body (32), allow it to fit all of the common household hammers. Alternative holding fingers (314, 316, 318 FIG. 20) handle nonmagnetic fasteners.

  • Patent number: 5213023
    Abstract: A hammer having unique structure in the handle receiving central portion of its hammer read unit. A wedge unit is formed from two intersecting wedge sections driven into the top end of the handle of the hammer causing the wood to be wedge outwardly in four directions within the handle receiving central portion of the hammer head unit. The wedge unit has a groove in the top surface of one of the wedge sections that allows a nail to be layed horizontally along the top surface of the wedge with part of the nail passing through grooves in the side walls of the handle receiving central portion of the hammer head unit. The wedge unit is also made of magnetic material thereby allowing the nail to be temporarily captured by the wedge unit during the initial stroke of the hammer.

  • Patent number: 5119699
    Abstract: A hammer including an elongate hammer head mounted orthogonally to a handle. The hammer head includes an impact head, wherein the impact head is defined by an impact face that defines an acute angle relative to the elongate handle axis of substantially 8 to 11.5 degrees to minimize strain and deflection upon an individual impacting a nail in use of the hammer. The impact face includes a semi-spherical recess to receive the nail and minimize deflection of various portions of the nail that may be fractured upon impact. A modification of the invention includes deformable inserts mounted within the semi-spherical recess for minimizing abrasion to various upholstery nails and the like upon impact.

  • Patent number: 4890518
    Abstract: A hammer having an improved head assembly. The hammer head assembly has a head portion, a shank portion, and a claw portion. The head portion has a front face having a triangular configuration. The head portion also has a horizontally oriented top wall and two side walls that converge downwardly toward their bottom ends where they meet. The center of the front face of the head portion lies on an axis that is perpendicular to the longitudinal axis of the handle and they intersect at the center of gravity of the hammer head assembly. The top end of the shank portion is flat so that the hammer can free stand on the surface. There is a rounded indentation between the shank portion and the claw portion so that it may be rested upon a block or cats paw for extra leverage. A T-shaped slot may be formed in the top end of the handle and it may have a related magnet for detachably capturing the head of a nail therein for hammering purposes.

  • Patent number: 4718313
    Abstract: A hammer head for a hammer which includes a nail-holding part which allows a nail to be initially driven in a wall by a worker using only one hand. The nail-holding part includes a striking surface which engages the head of a nail and a pair of pinching pieces which engage opposite sides of the shank of the nail therebetween. The pair of pinching pieces permit nails of various diameters to be held therebetween and the pair of pinching pieces are disposed adjacent to the striking wall for tightly holding the nail with the head of the nail in tight engagement with the striking wall. A groove is provided in the hammer head at a location further from the striking wall than the pinching pieces for supporting the shank of the nail. The nail-holding part is disposed within a recess in the hammer head and does not interfere with the normal operation of the hammer head.

  • Patent number: 4658679
    Abstract: A nail holding accessory for a hammer includes a body member having an upstanding pair of gripping fingers formed at a forward end thereof and an arcuate surface defined at a rearward end thereof. The pair of gripping fingers establish therebetween an open-ended slot for receiving and retaining a nail forwardly of a striking face of the hammer. An elastomeric band having a portion connected to the body member forwardly of the arcuate surface and a remaining portion adapted to encompass a transverse exterior section of the hammer rearwardly of the striking face thereof is provided for coupling the body member to the hammer such that the pair of gripping fingers are positioned forwardly of the striking face of the hammer. Rebound of the hammer away from a nail initially driven into a wooden board or like workpiece causes the gripping fingers to exert a pivot force on the body member thereby responsively pivoting the gripping fingers away from the striking face of the hammer to release the nail.
