Abstract
A cane system having an adjustable shock absorber, a multi-angle handle, a straight handle, and a knob.
Claims6
A cane system, relating to minimizing jarring shock and maximizing comfort of a user during use of a cane, comprising:
- a) at least one handle structured and arranged to permit user gripping of the cane;
- b) at least one walking-surface contactor structured and arranged to contact a walking surface;
- c) at least one continuous height adjuster structured and arranged to adjust the height of the cane continuously from a minimum height to a maximum height;
- and
- d) at least one shock absorber structured and arranged to absorb shock occurring, during use of the cane, between said at least one walking-surface contactor and said at least one handle;
- e) wherein said at least one shock absorber comprises at least one force adjuster structured and arranged to adjust a compression force of said at least one shock absorber;
- f) wherein said at least one continuous height adjuster comprises at least two telescoping tubes;
- g) wherein said at least one continuous height adjuster further comprises at least one friction-lock nut;
- h) wherein said at least one shock absorber comprises at least one compression spring;
- i) wherein said at least one shock absorber further comprises at least one shock compression-distance limiter structured and arranged to limit change in the compression distance of said at least one compression spring between said at least one walking-surface contactor and said at least one handle;
- j) wherein said at least one force adjuster comprises at least one compression adjuster structured and arranged to adjust the compression of said at least one compression spring while at minimum shock-compression;
- k) wherein said at least one force adjuster further comprises at least one adjustment limiter structured and arranged to limit adjustment distance;
- l) wherein said at least one force adjuster comprises at least one adjustment stop structured and arranged to adjustably stop one end of said at least one compression spring;
- m) wherein said at least one shock absorber compresses said at least one compression spring between at least one end of one tube of said at least two telescoping tubes and said at least one adjustment stop;
- n) wherein said at least one shock compression-distance limiter comprises
- i) at least one slot near said at least one end of said one tube, and
- ii) at least one pin structured and arranged to slide along the length of said at least one slot;
- o) wherein said at least one shock compression-distance limiter limits the compression distance to about the length of said at least one slot;
- p) wherein said at least one force adjuster alters the maximum distance between said at least one end of said one tube of said at least two telescoping tubes and said at least one adjustment stop;
- q) wherein said at least one adjustment limiter comprises
- i) at least one adjustment slot, and
- ii) at least one fastener rod structured and arranged to slide along the length of said at least one adjustment slot;
- r) wherein said at least one fastener rod couples with said at least one adjustment stop.
