Abstract

A comfort cane includes a cane shaft having an upper end and lower end thereof, and a two-piece handle affixed to the upper end of the cane shaft. The handle includes a rigid body portion substantially defining a profile of the handle in a top view of the handle, and a top portion attached to the body portion. The top portion is soft and resilient with respect to the body portion.

Claims (16)

1. A cane comprising

a cane shaft having an upper end and a lower end thereof; and

a two-piece handle affixed to the upper end of the cane shaft, the handle including a rigid body portion defining a low gripping surface of the handle, and a top portion attached to the body portion, the top portion being of soft and resilient material with respect to the body portion, thereby forming a hand grip having soft and resilient top and rigid bottom sides opposite to each other, the soft and resilient top portion in a longitudinal cross-sectional view of said top portion, having a middle area thicker than an area around the middle area to form an upward projection of the soft and resilient material extending from the top side, in order to allow impact absorption and solid gripping when a user's hand grasps the top and bottom sides of the hand grip, whereby the top portion mates substantially seamlessly with a cut off area of the body portion.

2. The cane as defined in claim 1 wherein the handle in a top view thereof comprises an increasing width from a front section of the handle towards a rear end of the handle.

3. The cane as defined in claim 2 wherein the handle comprises an upstanding shoulder at the rear end extending upwardly from the top portion of the handle and a heel at the rear end extending downwardly from the body portion of the handle.

4. The cane as defined in claim 1 wherein the top portion comprises a surface having more frictional resistance than a surface of the body portion.

5. The cane as defined in claim 1 wherein the body portion defines a hole therein, the upper end of the cane shaft being engaged in the hole such that the cane shaft is oriented in a desired angle with respect to an axis of the hand grip.

6. The cane as defined in claim 5 wherein the hole is defined in a front end of the handle formed by the body portion, the hole extending into the body portion substantially along the axis of the hand grip while an upper section of the cane shaft is bent to provide the desired angle between the upper end and the lower end of the cane shaft.

7. The cane as defined in claim 6 wherein the front end of the handle is formed by an end section of the body portion including a radially protruding annular ridge.

8. The cane as defined in claim 5 wherein the handle comprises a downward section formed by the body portion, the downward section extending downwardly in the desired angle with respect to an axis of the hand grip, the hole being defined in an end of the downward section and extending thereinto for engagement with the upper end of the cane shaft.

9. The cane as defined in claim 8 wherein the handle comprises a front section substantially formed by the body portion, the downward section of the handle being located between the front section and the hand grip.

10. The cane as defined in claim 1 wherein the cane shaft is adjustable in length.

11. The cane as defined in claim 1 comprising a tip of soft and resilient material attached to the lower end of the cane shaft.

12. The cane as defined in claim 11 wherein the tip comprises a body defining a hole in a top thereof for engagement with the lower end of the cane shaft and having a substantially triangular bottom thereof, the body tapering from the substantially triangular bottom towards the top and changing into a substantially round shape at the top.
