  • Patent number: 4651991
    Abstract: A secondary covering for the gripped portion of manipulative handles having a primary non-slip covering is comprised of an elongated strip of terrycloth fabric having a doubly convergent taper at each extremity and two lengths of strong thin tether line attached to each extremity. The covering is adapted to be wound in spiral fashion about the handle, both extremities being secured by the tether lines to the handle, the tether lines of the upper extremity of the winding being secured with plastic adhesive tape. By virtue of its construction and manner of application, the covering provides a cushioned gripping surface relatively unaffected by moisture, and preserving the natural "feel" of the handle.
