Remote Control Ground Exchangeable Tips Patents (Class 135/70)
  • Patent number: 10413026
    Abstract: A reacher attachment assembly of use with a cane. The attachment assembly attaches a reacher to a cane such that the reacher is stored out of the way of the tip of the cane so as not to interfere with the cane when the reacher is not in use, but allows the reacher to be slid into position for use so that the cane tip does not interfere with the reacher. The attachment assembly may comprise a distal mount securely attached to the cane and slidingly attached to the reacher, a spring mount securely attached to the reacher, and a spring between the distal mount and the spring mount, such that the spring retains the reacher out of the way when not needed but allows the reacher to be extended downward relative to the cane for use.

  • Patent number: 8978677
    Abstract: An improved cane with an internal grasping apparatus including an actuator on the cane handle and a plurality of clamps that extends from the foot or base of the cane. A cord system within the casing of the cane connects the actuator to the clamps so that when the actuator is in use, the clamps close or open to either grasp or release objects, depending on the amount of pressure applied to the actuator. Applying pressure to the actuator extends a plurality of clamps from the distal end of the cane that can be used to assist with grasping of objects. Releasing pressure to the actuator on the cane handle will retract the clamps back into the distal end of the cane to where the clamps are hidden.

  • Patent number: 6386216
    Abstract: An upper tubular member is telescoped within a lower sleeve or sheath having a cane foot at its lowermost end. The sleeve is adjustably set along the member to set the length of the cane by a detent assembly employing a pawl and aperture arrangement. An article grasping mechanism is located at the lower end of the upper tubular member and includes a pair of toothed jaws with meshing teeth. The jaws extend from the tubular member at one end, opposite a handle attached to the tubular member at the other end. A lever is attached at the handle end and is coupled to the jaws via cables and pulleys. The jaws are biased open and are closed by the cables as the handle is squeezed closed. The sleeve encloses the jaws in the closed state when not in use. When the sleeve is removed from juxtaposition over the jaws, the jaws are biased open by torsion springs. The handle and lever are then used to close the open jaws over an article to be grasped.

  • Patent number: 5636651
    Abstract: A controller for wheeled vehicles includes a mechanism which selectively shifts the vehicle between a mobile and a stable state. The vehicle may be a walker for easing an operator's efforts in walking and includes a selectively actuable stabilizer which fixes the position of the walker or releases it for rolling motion, thus providing a stable state or a mobile state, respectively. An actuator such as a button, pressure sensor, or lever, electrically and/or mechanically actuates a stabilizer brake mechanism to engage or release the brake and thereby allow the walker's mobility to be controlled when the actuator operates the brake to stabilize or to slow the motion of the walker. Preferably, lift applied to the vehicle itself releases the brake and allows mobility. The actuator may control an electrically actuated braking mechanism, in response to a sensor such as a strain gauge that may be adjusted to the needs of the patient; alternatively, lifters may be provided to act in response to the lifting force.
