ABSTRACT:
A pivoting tip assembly for a walking cane, which accommodates both tilting and rotation of the shaft of the cane while the base of the tip remains in stationary engagement with the floor. A disk member is mounted to the lower end of the shaft for rotation about the long axis thereof, and has a rounded outer edge which engages the inner surface of a socket formed in the rubber tip. The disk member is sized to have a sliding fit with the inside surface of the socket, so that the disk is able to tilt within the socket as the shaft of the cane tilts back and forth. The opening at the top of the socket is sized larger than the shaft, so that the shaft can tilt through a predetermined range of angular movement before striking the lip of the cup; at the limit of travel, the shaft comes into contact with the resilient material of the cup, which provides a yielding stop to the tilting motion. A radial skirt is mounted to the shaft above the tip assembly, which permits the operator to retrieve the cane without having to bend over, by stepping on the tip of the cane and then sliding a foot under the upper end of the shaft so as to pivot the cane to a position in which the handle is within reach.
