<p>The walker glide is a spherical attachment for removable installation over the lower end of a walker leg or other legged article. The glide is formed of a hollow, resilient ball and includes a plurality of leg attachment holes therethrough. No two holes are aligned directly and diametrically opposite one another. Any hole always has an unbroken ball surface directly diametrically across therefrom. This allows any given hole of the ball to be placed over the end of the leg, while assuring that the leg tip will bear against the opposite unbroken surface of the ball. When the bearing surface of the ball becomes worn, the user need only remove the ball and reorient it by installing it on the leg using another hole to provide a fresh bearing surface for the ball. While any suitable type of ball may be used, tennis balls have been found to work well.</p> |
