Abstract
An improved crutch includes an improved shock absorbing mechanism, lighting components, and an improved tip component. The improved shock absorber mechanism utilizes compressible spheres that are compressed when a person supports all or partial of their body weight onto the crutch and are uncompressed when the weigh is removed. This compression of the spheres absorbs any impact from the walking surface to the person's body. The elasticity of the compressible spheres is adjusted by forming a central through-opening through the sphere, varying the number of the sphere, their diameter and material.
Claims19
An improved crutch comprising:
- a first shock absorbing post comprising a first elongated tube, a second elongated tube and an intermediary tubular component positioned between the first elongated tube and the second elongated tube and wherein the intermediary tubular component comprises a central opening extending between a first end and a second end and is sized and shaped to slidably receive a first end of the first elongated tube into the first end of the central opening and a first end of the second elongated tube into the second end of the central opening;
- wherein the first elongated tube comprises an opening and the intermediary tubular component comprises an elongated slot and wherein the first elongated tube is configured to be secured to the intermediary tubular component via a removable pin that is inserted into the elongated slot of the intermediary tubular component and the opening of the first elongated tube;
- wherein the intermediary tubular component further comprises one or more shock absorbing components that are positioned within the central opening and wherein sliding of the first elongated tube into or out of the central opening of the intermediary tubular component compresses or decompresses the shock absorbing components, respectively;
- and
- wherein the shock absorbing components comprise compressible spheres and the compressible spheres are solid and comprise a center through-opening.
