  • Patent number: 5992434
    Abstract: An enlarged and weighted tip for replacing a multi-pod tip of a cane and for receiving a lower end of the cane and for allowing the cane to stand by itself. The tip includes a body portion that is shaped like a frustrum of substantially a pyramid. The body portion has a cavity therein that is disk-shaped and is disposed axially between the bore in the top surface of the body portion and the base of the body portion, parallel thereto. The tip further includes a plate that completely fills the cavity in the body portion and provides structural integrity, prevents rupturing of the base of the body portion caused by weight bearing on the cane tending to push it downwardly, and which adds sufficient weight to lower the center of gravity enabling the cane to stand by itself.
