  • Impact responsive extendible arm pick-up for walking canes or the like
    Patent number: 6068007
    Abstract: A retrieval mechanism for extending an arm from a fallen elongated walking appliance, such as a walking cane or crutch, to enable the appliance to be retrieved without requiring any bending over by the person retrieving the appliance. An elongated arm is spring biased to an actuator mechanism and the actuator mechanism includes structure for retaining the arm in non-extended relation parallel to the axis of the elongated walking appliance and for extending the arm therefrom responsive to impact of a transverse member on the extendible arm with the surface upon which the walking appliance has fallen.
    Type: Grant

  • Impact responsive extendiable arm pick-up for walking cane or the like
    Patent number: 6039064
    Abstract: An arm extending assembly for attachment to a walking appliance such as a walking cane, to enable the appliance to be retrieved without requiring the user to bend over. The device extends an extendible arm upwardly in a direction normal to the surface upon which the walking appliance has fallen. The arm is extended responsive to impact of the assembly on the surface, such as the ground. The arm extending assembly includes a base member for attachment to a cane, an actuating mechanism including a spring biased rotatable arm for imparting rotation to the extendible arm, a spring biased locking mechanism for releasably locking the actuating mechanism to the housing and ground engaging means operatively connected to the spring biased locking mechanism for release of the locking mechanism to permit rotation of the rotatable arm of the actuating mechanism and, thus, rotation of the extendible arm responsive to impact of said ground engaging means with the ground or surface.
