Abstract
A walking aid device is disclosed which permits a user to increase his stride without requiring auxiliary elements that slide or roll, and makes use only of the muscles normally used in walking. The device has a lower part-circular base made of non-skid material and extending over an angular sector corresponding to a subtending chord of length equal to 1.5 times its radius of curvature, and a board fixed across the base equidistantly from the ends of the base, to receive the users foot. The board is equal in length to the radius of curvature of the base.
Claims3
A walking aid device which facilitates the normal forward movement of a walker on foot, without requiring a sliding movement or a rolling movement of auxiliary elements, and which requires use only of the muscles normally used in walking, the device comprising;
- a lower part-circular base which is made of a non-skid material, has a width which is slightly less than that of the foot of a potential user, and extends over an angular sector corresponding to at least a subtending chord of a length equal to essentially 1.5 times the radius of curvature of said part-circular base;
- a platform of essentially the same width as said part-circular base, and firmly fixed to the base and equidistant from the ends of said part-circular base, said platform being within said base and having an upwardly facing foot supporting surface lying essentially along a chord of said base of a length equal to said radius of curvature and which subtends an angular sector of 60 degrees of the base and is equidistant from the ends of said base;
- and
- means for securing the user's foot to said platform against movement relative to said base.
