Abstract
A floor system has removable floor panels resting at their corners on support rings provided by vertically adjustable pedestal units. The upper ends of the pedestal units have hex-heads for receiving a height adjusting tool. Access to the hex-heads is obtained by removing cornercaps held in place by screws threaded into the hex-heads. The support rings do not turn while the pedestal units are being adjusted in height.
Claims18
A floor system comprising:
- a pedestal including a base member and a column screw-mounted on said base member for up and down movement responsive to turning of said column relative to said base member about a vertical axis, said column having a head portion adapted to receive a tool for turning said column;
- coplaner horizontal panels partly supported on said column, and leaving a top access area to the top of said column such that said column can be turned by said tool for height adjustment relative to said panels and base member, the upper surface of said panels being at a level higher than the upper end of said head portion;
- a removable cap overlapping portions of said panels in said access area and flush at the top with surfaces of said panels,
- and a hold-down screw extending through said cap into said head portion of the column.

A floor system comprising:
- like generally rectangular floor panels arranged in like rows forming a floor surface interrupted by square openings at regular intervals where adjacent corner portions of four of said panels meet;
- square caps filling said square openings;
- and respective gaskets surrounding each of said panels and said caps, said gaskets being arranged such that adjacent of said gaskets engage one another to seal between said panels and between said panels and caps.
A pedestal for supporting floor panels in a floor system, said pedestal comprising:
- a base member;
- a column screw-mounted on said base for up and down movement responsive to turning of said column relative to said base, said column having a head adapted to receive a tool for turning, said column, and having an upwardly facing annular seat;
- and
- a panel support ring sleeved on said column below said head and carried by said seat such that said column can be turned relative to said ring for height adjustment of the ring and related panels supported thereon.
