Telescoping adjustable leg
The telescoping adjustable leg comprises a tubular housing, a tubular toe, a cylindrical toe, a base and an externally threaded rod. The adjustable leg 10 is expandable from a fully retracted position to a fully extended position by rotation of the housing and cylindrical toe relative to the tubular toe.
1. 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.
2. An adjustable leg as set forth in claim 1 wherein said tubular housing has a radially inwardly directed flange at a lower end thereof for abutment of said tubular toe thereon in said extended position of said tubular toe.
3. An adjustable leg as set forth in claim 2 wherein said tubular toe has a radially inwardly directed flange at a lower end thereof for abutment of said collar of said cylindrical toe thereon in said extended position of said cylindrical toe.
4. An adjustable leg as set forth in claim 1 wherein said base is fixedly secured to said cylindrical toe and is of larger diameter than said tubular toe.
5. An adjustable leg as set forth in claim 1 wherein said externally threaded rod is fixedly mounted in said tubular housing.
6. An adjustable leg as set forth in claim 1 further comprising a washer having an internally threaded bore secured within an upper end of said tubular housing and having said rod threaded into said bore.
7. An adjustable leg comprising:
a tubular housing having an internal thread and at least a pair of oppositely disposed fiats on an outer surface thereof;
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;
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.
8. An adjustable leg comprising
a tubular housing having an internal thread, an annular recess at an upper one end and a radially inwardly directed flange at an opposite lower end thereof;
a tubular toe having an internal thread, a collar at one an upper 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, a radially inwardly directed flange at an opposite lower end thereof 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;
a washer having an internally threaded bore secured within said annular recess of said tubular housing; and
an externally threaded rod threaded into said bore and projecting from said washer and said tubular housing.
9. An adjustable leg as set forth in claim 8 wherein said base has at least a pair of oppositely disposed flats on an outer surface thereof.
10. An adjustable leg comprising
a tubular housing having an internal thread, an annular recess at an upper one end, a radially inwardly directed flange at an opposite lower end thereof and at least a pair of oppositely disposed flats on an outer surface thereof;
a tubular toe having an internal thread, a collar at one an upper 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 and a radially inwardly directed flange at an opposite lower end 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;
a washer having an internally threaded bore secured within said annular recess of said tubular housing; and
an externally threaded rod threaded into said bore and projecting from said washer and said tubular housing.
