Abstract:
1. A kit for a crutch having a tubular main body of a first predetermined diameter defining a lower end of said tubular main body and an extension member of a second predetermined diameter able to freely telescopically slide into and out of said tubular main body, said kit comprising: a sleeve attachable to said lower end of said tubular main body; a recess in said sleeve to receive said lower end of said tubular main body; an opening in said sleeve to receive said extension member therethrough; an interior ledge formed inside said sleeve between said recess and said opening to engage against said lower end of said tubular main body; an extension boss extending from said sleeve around said opening; a collar attachable to said extension member, in turn comprising: a resilient device positioned on said boss of said sleeve and on said formation of said collar whereby pressure on said tubular main body will cause telescoping movement of said extension member into said tubular main body and will stress the said resilient device, and release of pressure will permit movement of said extension member from said tubular main body and will relax such stress.
