Claim 2

A support and leveling arrangement comprising an adjustable leg portion; a socket for receiving said adjustable leg Portion and having a generally oval shaped cross section, said socket formed intergral with and deformed from a web and comprised of one semi-oval band projecting out of said web in one direction and a pair of upstanding semi-oval bands located on either side of said one band and projecting out of said web in the other direction; said adjustable leg portion having a longitudinal member having a substantially oval cross section along at least a part of its length, said adjustable leg portion being relatively freely movable axially in said socket when the oval cross sections of said socket and said adjustable leg portion are in registry, said oval cross sections of said socket and said adjustable leg portion providing an interference lock between said socket portion and said adjustable leg portion in any adjusted position of said adjustable leg portion when said adjustable leg portion is rotated relative to said socket portion; and means for rotating said adjustable leg portion relative to said socket portion.

Claim 3

A support and leveling arrangement comprising: a leg having a top and bottom end; means forming an axially extending socket in which said leg is received for axial adjustment therewithin, said socket formed intergral with and deformed from a web and comprised of one semi-oval band projecting out of said web in one direction and a pair of upstanding, semi-oval bands located on either side of said one band and projecting out of said web in the other direction, said socket having in its projected cross section a generally oval shape; said leg having along at least that part of its length subject to being in facing relation with said socket in the range of adjustment of said leg relative to said socket, a generally oval shaped cross section of a transverse dimension permitting relatively free axial movement of said leg within said socket when said oval shaped cross sections are in registry, and providing an interference lock between said leg and socket when said leg is rotated relative to said socket; and a foot extending generally at a right angle at said bottom end of said leg for facilitating rotation of said leg within said socket.

Claim 4

A support and leveling arrangement comprising: a leg having a top and bottom end; means forming an axially extending socket in which said leg is received for axial adjustment therewithin, said socket formed intergral with and deformed from a web and comprised of one semi-oval band projecting out of said web in one direction and a pair of upstanding, semi-oval bands located on either side of said one band and projecting out of said web in the other direction, said socket having in its projected cross section a generally oval shape; said leg having along at least that part of its length subject to being in facing relation with said socket in the range of adjustment of said leg relative to said socket, a generally oval shaped cross section of a transverse dimension permitting relatively free axial movement of said leg within said socket when said oval shaped cross sections are in registry, and providing an interference lock between said leg and socket when said leg is rotated relative to said socket; and a foot extending generally at a right angle at said bottom end of said leg for facilitating rotation of said leg within said socket.

Claim 5

The arrangement of claim 2 wherein: said foot includes an upwardly inclined toe to facilitate rotation of said leg when said leg is resting on a surface.
