Abstract

Claims (31)

1. An apparatus for aiding walking along a surface, comprising:

a handle for engaging a hand of a user of the apparatus;

a shaft coupled to the handle at a first end and extending away from the handle, the shaft including one or more shaft sections;

a base coupled to the shaft at a second end of the shaft, the base having an upper housing and a lower housing that define an internal cavity therebetween;

three flexible footpads mounted to a main body of the base and configured to interface with the surface, each footpad having concentric rings of raised and recessed portions, the three flexible footpads arranged substantially equidistant from a central axis of the internal cavity of the base such that the three flexible footpads form a substantially equilateral triangle;

an elastically bendable member at least partially enclosed within the internal cavity of the base such that an axis of the elastically bendable member is generally aligned with a central axis of the internal cavity of the base;

a fastener extending along the axis of the elastically bendable member and through at least a portion of the base so as to coupled the base and the elastically bendable member to a lowermost shaft section of the shaft;

wherein the fastener includes: (i) a bolt extending along the axis of the elastically bendable member and through at least a portion of the base, and (ii) at least one securing nut disposed within a lowermost shaft section of the shaft, the at least one securing nut affixed to the bolt and configured to engage an inner wall of the lowermost shaft section to secure the base to the lowermost shaft section.

2. The apparatus of claim 1 , wherein at least one recessed portion of each footpad is defined by at least two raised portions of each footpad.

3. The apparatus of claim 1 , wherein each footpad contacts a portion of the base so as to restrict rotation of each footpad.

4. The apparatus of claim 1 , wherein the elastically bendable member biases the shaft to a first orientation relative to the base and elastically flexes in response to pivoting movement of the shaft from the first orientation to a second orientation relative to the foot.

5. The apparatus of claim 1 , wherein the elastically bendable member is located between the upper housing and the lower housing.

6. The apparatus of claim 5 , wherein a bottom portion of the fastener extends below the elastically bendable member.

7. The apparatus of claim 6 , wherein the bottom portion of the fastener is disposed within the internal cavity defined by the upper housing of the base and the lower housing of the base.

8. The apparatus of claim 1 , wherein the fastener is configured to impart torque upon the elastically bendable member in response to an angular movement of the shaft with respect to the base.

9. The apparatus of claim 8 , wherein at least a portion of the elastically bendable member is configured to elastically compress in response to the angular movement of the shaft with respect to the base.

10. The apparatus of claim 1 , wherein the at least one securing nut engages the inner wall of the lowermost shaft section by digging into material of the lowermost shaft section to anchor the at least one securing nut within the lowermost shaft section.

11. The apparatus of claim 10 , wherein the at least one securing nut digs into the material of the lowermost shaft section in response to tension created by tightening of the bolt.

12. The apparatus of claim 1 , wherein:

the shaft comprises three shaft sections configured to detachably release from each other; and

the apparatus is configured to fold into a collapsed configuration in which central axes of each of the shaft sections are substantially parallel and not aligned, wherein the handle is positioned at a top portion of the apparatus and the base is positioned at a bottom portion of the apparatus when the apparatus is in the collapsed configuration.

13. The apparatus of claim 12 , further comprising an attaching member configured to engage each of the three shaft sections and secure the three shaft sections to each other when the apparatus is in the collapsed configuration.

14. An apparatus for aiding walking along a surface, comprising:

a handle for engaging a hand of a user of the apparatus;

a shaft coupled to the handle at a first end and extending away from the handle, the shaft including one or more shaft sections;

a base coupled to the shaft at a second end of the shaft, the base having an upper housing and a lower housing that define an internal cavity therebetween;

three flexible footpads mounted to a main body of the base and configured to interface with the surface, each of the three flexible footpads having concentric rings of raised and recessed portions;

an elastically bendable member at least partially enclosed within the internal cavity of the base such that an axis of the elastically bendable member is generally aligned with a central axis of the internal cavity of the base;

a fastener extending along the axis of the elastically bendable member and through at least a portion of the base so as to couple the base and the elastically bendable member to a lowermost shaft section of the shaft;

wherein the fastener includes: (i) a bolt extending along the axis of the elastically bendable member and through at least a portion of the base, and (ii) at least one securing nut disposed within a lowermost shaft section of the shaft, the at least one securing nut affixed to the bolt and configured to engage an inner wall of the lowermost shaft section to secure the base to the lowermost shaft section;

wherein the at least one securing nut engages the inner wall of the lowermost shaft section by digging into material of the lowermost shaft section to anchor the at least one securing nut within the lowermost shaft section.
