  • Patent number: 8555907
    Abstract: A retractable, non-slip tip system for support devices such as canes and crutches is provided. The system includes a hollow body having openings on each of a proximal end and a distal end. The body is configured to slide over the shaft of a support device and affix to the support device in either an extended position, wherein the distal end of the body extends beyond a terminal end of the support device, or a retracted position, wherein the terminal end of the support device extends beyond the distal end of the body. Suitably placed apertures in each of the body and the support device facilitate the attachment of the body to the support device in the extended and retracted positions. When the body is in the extended position, gripping protrusions on the distal end of the body are exposed and provide extra traction for the support device on soft slippery surfaces.

  • Patent number: 7377551
    Abstract: A collapsible snowboard pole is presented. In exemplary embodiments of the present invention a snowboard pole can be provided with a manually expandable and compressible shaft, a basket at the tip, and a handle at the top. The basket can slide between a lower tip-ward (distal) position for storage and an upper top-ward (proximal) position for use. In exemplary embodiments of the present invention the pole can be expanded to full length and disengaged from a docking mechanism located at the back of a snowboard with one hand, while a user is in motion on the snowboard. Once disengaged, the user can easily deploy the basket to its full upward extension for use. Additionally, a user can dock a collapsed pole and secure it in a docking mechanism, or can insert the pole tip in a docking mechanism, then collapse the pole and then secure it in the docking mechanism, all with one hand while in motion on the snowboard.

  • Patent number: 6488042
    Abstract: A walking cane having a multifunctional handle, where the handle, which outwardly appears to be a conventional handle, is comprised of articulating elements which can be rotated outwardly, therein transforming the handle into a tripod like structure. The cane then becomes self-standing when inverted. Magnets are used to hold the articulating elements in position in the unified form, and the proximity of these magnets may have some therapeutic value.

  • Patent number: 4977914
    Abstract: A slip resistent apparatus for walking aids such as canes, crutches and walkers is disclosed. The apparatus provides a spring biased, lever actuated, selectively operable, ground engaging probe slidingly displaced within the vertical structure of the walking aid. The probe is a pointed elongate rod. A hand operated lever with attached actuating arm is affixed to the walking aid and rests against the upper portion of the rod. Actuation of the lever transmits a compressive force to the spring biased probe extending the pointed tip to make engagement with the ground, thus providing a slip resistant walking aid. The sliding rod is adjustable in length to accommodate different heights of walking aids and is adapted to fit the different types of walking aids including canes, crutches and walkers.
