  • Patent number: 4730632
    Abstract: A cane having a one piece molded handle with a roughened area on the handle's top surface to increase gripping friction with the user's hand, upstanding shoulders at the front and rear ends of the handle that prevents the user's hand from slipping off the handle, and index finger support ribs to enhance control of the cane during use. The handle is preferably connected to a tubular shaft by a fastenerless lock that includes a stub shaft formed integral with the handle, that stub shaft having a series of lock flanges oriented generally normal to the stub shaft's axis that, prior to assembly, are of a slightly greater outside diameter than the inside diameter of the tubular shaft, so that the lock flanges are deformed upwardly in generally dish-shaped configuration when the handle's stub shaft is inserted into the tubular shaft.
