  • Publication number: 20120132040
    Abstract: A hand tool includes a rigid levers having a handle portions and jaw portions. The levers are pivotably interconnected to allow the jaws to move between an open position and a closed position. The hand tool further includes a resilient handle member having a first end and a second end opposite the first end. The first end of the resilient handle member is joined to the handle portion of the first lever, the second end of the resilient handle member is joined to the handle portion of the second lever. The resilient handle member extends in a substantially U-shaped configuration from the handle portions of the first and second levers. Pivoting of the first and second levers moving the jaws to the closed position causes temporary deformation of said handle member, and resiling of the handle member moves the jaws toward the open position.

  • Publication number: 20120011970
    Abstract: Pliers with a restoring function include an elastic element and two pliers bodies. The elastic element has two urging ends. The two pliers bodies have two pinching heads, two handles, and two pivotal parts. Each of the pivotal parts has a recess and a pivotal hole. A pivotal element goes through the two pivotal holes. The elastic element is disposed in the two recesses and penetrated by the pivotal element. Both urging ends of the elastic element are on opposite sides of the two recesses to urge sidewalls of the recesses, thereby opening the pliers. A buffer region is designed in each of the recesses for the corresponding urging end. When the opening angle of the pliers is greater than that is supported by the elastic element, at least one urging end of the elastic element releases its urging against the recess sidewall and moves in the buffer region. The pliers become relaxed then.

  • Patent number: 7140278
    Abstract: A pair of manual tongs comprising two limbs which are rotatably connected in a common first rotational axis. The first limb is separated into two levers in its lever section, the two levers being rotatably connected in a first articulation, in a second rotational axis parallel to the common first rotational axis. A means of traction connects the second limb to the lever of the first limb, which is situated at a distance from the handle. The means of traction can be shortened by means of a pivotal movement of the lever of the first limb, which is situated close to the handle, above the second rotational axis. The areas of use of the manual tongs are often difficult to access. According to the invention, the second limb of the inventive manual tongs is thus separated into a lever situated at a distance from the handle and a lever situated close to the handle and the two levers are rotatably connected in a second articulation, in a third rotational axis which is parallel to the common first rotational axis.

  • Patent number: 6941628
    Abstract: The invention comprises tools for forming beads on one or more filaments using a malleable material for the bead. The tools exert bead-forming forces radially inward toward the filament and axially along the filament toward the center of the bead. The tools comprise pliers with jaws which meet flush with each other over at least a portion of the jaw face. Aligned cavities are formed in each jaw face wherein each cavity's dimension across the jaw face is less than the width of the jaw face. Grooves, aligned generally transverse to the width of the jaw face provide a filament-receiving channel between the cavity and the edge of the jaw face. Malleable material encompassing the filament is aligned between the aligned cavities and the jaws are closed. The radial force of the cavity walls on the malleable material deforms the malleable material radially and the walls of the cavity exert a force axially to form a bead.

The jaws are dimensioned to be slightly elastic and have their meeting faces angled so the faces diverge from the front back toward the hinge and increased pressure on the handle will clamp and deflect the jaws until the faces are in abutment and stops on the handle side of the hinge limit and prevent the jaw deflection movement beyond their full abutment disposition. A plastic resilient member acts on the handles to urge them apart. Auxiliary gripping devices can be attached to extend beyond the nose portions of the jaws.
