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.

Description

In order to provide a better understanding, a preferred embodiment of the present invention will now be described in detail, by way of example only, with reference to the accompanying drawings, in which:

FIG. 1 is an upper perspective view of a wear indicating foot in accordance with the present invention;

FIG. 2 is a cross-sectional side view of the wear indicating foot of FIG. 1;

FIG. 3 is a cross-sectional side view of the foot of FIGS. 1 and 2, having been worn through use;

FIG. 4 is a cross-sectional side view of an alternative wear indicating foot, in accordance with the present invention, with a pivotal attachment between a base of the foot and a leg coupling means of the foot;

FIG. 5 is the foot of FIG. 4 showing the base in a pivoted position; and

FIG. 6 is an upper perspective view of a mobility assisting device including a wear indicating foot of the present invention.

Claims

1. A wear indicating foot, for use on the bottom of a leg of a mobility assisting device, said foot comprising:

2. A wear indicating foot in accordance with claim 1, wherein the foot includes a plurality of voids spaced around the base.

3. A wear indicating foot in accordance with claim 2, wherein said plurality of voids are in the form of at least one of a notch in the side of the base portion, a recessed hole and a combination of at least one notch and at least one recessed hole.

4. A wear indicating foot in accordance with claim 1, wherein the base includes an attachment portion for connecting the foot to the leg and a replaceable wearing portion that includes the bottom surface, the attachment portion including the upper surface, and said at least one void opening.

5. A wear indicating foot in accordance with claim 1, wherein at said at least one void opening is in the form of at least one of a recessed hole, a notch and a combination of said recessed hole and said notch.

6. A wear indicating foot in accordance with claim 1, wherein a replaceable wearing portion is pivotally attached to the attachment portion.

7. A wear indicating foot in accordance with claim 1, wherein the base is in the form of a glide tip whereby said bottom surface glides over the ground in use.

8. A mobility assisting device, comprising:

9. A mobility assisting device in accordance with claim 8, wherein the mobility assisting device includes a plurality of voids spaced around the base.

10. A mobility assisting device in accordance with claim 8, wherein the base includes a first portion attached to the coupling means and a second portion that includes the bottom surface, the first portion including the upper surface and said at least one void opening.

11. A mobility assisting device in accordance with claim 10 wherein the first portion is pivotally coupled to the second portion.

12. A mobility assisting device in accordance with claim 8, wherein said at least one void opening is in the form of a recessed hole.

13. A mobility assisting device in accordance with claim 8, wherein said at least one void opening is in the form of a notch in the side of the base.

14. A mobility assisting device in accordance with claim 8, wherein the base is in the form of a glide tip whereby said bottom surface glides over the ground in use.

15. A walking frame comprising:
