Abstract
A knockdown metal table having legs and a flanged top and including auxiliary components such as a drop leaf and modesty panel having attaching means which in assembly are clamped between the legs and the table flanges. A lift assembly including casters is attached to the legs and is adapted to be selectively actuated to move first one pair of casters and then the other into or out of engagement with a floor surface to permit rolling of the table over said floor surface or to rest the table on the floor surface in a desired position.

In combination a generally rectangular table and an auxiliary component removably attached thereto, said table including a horizontal member having depending flanges forming a plurality of corners, and a plurality of legs each being defined by four sides with adjacent sides being perpendicular so that said legs are generally square shaped in cross section, a diagonal connecting member at each of said corners, each of said diagonal connecting members having threaded means, a screw member received in each of said threaded means, said screw members being adjustable relative to said legs, a U-shaped member diagonally positioned and engaged by each of said screw members with spaced sides of each of said U-shaped members engaging the innermost right angle corner of one of said legs and adapted to apply pressure against said leg to hold said leg in one of said corners formed by said depending flanges, said screw members when retracted permitting removal of said legs, said auxiliary component including a pair of spaced attaching means each having a flat portion with each such portion being adapted to be received between a corresponding one of said legs and flanges before the screw member is adjusted to secure said leg to one of said corners formed by said depending flanges.
In combination with a table having two pairs of legs, lift means including a plate member secured to each of said pairs of legs, two pairs of lift arms with each of said pairs of lift arms pivotally secured intermediate its ends to one of said plate members with the inner ends of said pairs of lift arms overlapping each other, a caster supported at the outer end of each of said lift arms, a lift rod journalled in said plate members and having a pair of cam elements with one disposed at each end so as to engage the inner ends of a respective pair of said lift arms, means for rotating said lift rods so as to effect sequential engagement of said cam elements first with one of said pairs of lift arms and then with the other of said pairs of lift arms so as to effect substantially vertical movement of said casters, one delayed behind the other, into or away from engagement with a floor space to thereby elevate or lower said table.
