  • Shackle element for clamping a fixation rod, a method for making a shackle element, a hook with a shackle element and a rode connector with a shackle element
    Patent number: 6749361
    Abstract: A shackle element, a method of making a shackle element, a hook and a rod connector. The shackle element (18) is used for fastening a hook (12), or respectively a rod connector, on a fixation rod (10). The shackle element (18) forms a groove with a lateral opening for inserting the fixation rod (10). The groove is delimited by a groove bottom (18.1) and two lateral walls (18.2, 18.3). After mounting the groove bottom (18.1) encloses the fixation rod (10) over an angle of 180° plus a partial angle. The lateral walls are arranged under a small angle; their distance increases with growing distance from the groove bottom so that the lateral opening is large enough for introducing the rod. The lateral walls are intended to be pushed together by means of a screw device (20.1, 20.2) for clamping the fixation rod (10). The groove bottom (18.1) encloses the fixation rod (10) over an angle of 180° plus a partial angle.
