Abstract
A wear indicating foot for use on the bottom of a leg of a mobility assisting device having a coupler for coupling the foot to the leg. A ground engaging base opposite the leg has a bottom surface for contact with the ground. An upper surface extends laterally from the coupler opposite the bottom surface. At least one void opening on the upper surface extends into the ground engaging base in a direction towards the bottom surface. The at least one void opening has a predetermined depth so that excessive wear of the bottom surface is indicated by the bottom surface contacting the void opening.
Claims15
A wear indicating foot, for use on the bottom of a leg of a mobility assisting device, said foot comprising:
- a coupling means for coupling the foot to said leg;
- a ground engaging base attached to an end of the coupling means opposite the leg, said base having a bottom surface for contact with the ground and an upper surface extending laterally from the coupling means substantially opposite the bottom surface;
- and
- at least one void opening on the upper surface and extending into the base to a predetermined depth in a direction generally towards the bottom surface,
- whereby, in use, excessive wearing of the bottom surface is indicated when the bottom surface of the base is worn away to the extent that the bottom surface meets the void.
A mobility assisting device, comprising:
- at least one leg;
- and a wear indicating foot, coupled to an end of at least one leg, paid wear indicating foot including:
- a coupling means for coupling the foot to said leg;
- a ground engaging base attached to the coupling means, said base having a bottom surface for contact with the ground and an upper surface extending laterally from the coupling means substantially opposite the bottom surface;
- and
- at least one void opening on the upper surface and extending into the base to a predetermined depth in a direction generally towards the bottom surface,
- whereby, in use, excessive wearing of the bottom surface is indicated when the bottom surface of the base is worn away to the extent that the bottom surface meets the void opening.
A walking frame comprising:
- a framework having at least two support legs;
- at least one of said support legs having a respective wear indicating foot coupled thereto;
- paid wear indicating foot including;
- a coupling means for coupling said respective foot to said leg;
- a ground engaging base attached to the coupling means, said base having a bottom surface for contact with the ground and an upper surface extending laterally from the coupling means substantially opposite the bottom surface;
- and
- at least one void opening on the upper surface and extending into the base to a predetermined depth in a direction generally towards the bottom surface,
- whereby, in use, excessive wearing of the bottom surface is indicated when the bottom surface of the base is worn away to the extent that the bottom surface meets the void.
