Claims10
An adjustable leg comprising
- a tubular housing having an internal thread;
- a tubular toe having a collar at one end thereof threadably mounted in said tubular housing for movement of said tubular toe between a retracted position within said tubular housing and an extended position projecting from said tubular housing, said tubular toe having an internal thread and at least a pair of oppositely disposed flats on an outer surface thereof;
- a cylindrical toe having a collar at one end thereof threadably mounted in said tubular toe for movement between a retracted position within said tubular toe and an extended position projecting from said tubular toe;
- a base secured to a bottom end of said cylindrical toe and being of larger diameter than said cylindrical toe and having a flat bottom for resting on a flat support surface;
- and
- an externally threaded rod mounted in and projecting from said tubular housing.
