Abstract

A pedestal head for a floor panel comprises includes a base for a lower part of a floor panel and an upper support for receiving an upper part of a floor panel. The pedestal head has a receiver or projection for receiving and locating a corresponding projection or receiver of the floor panel The pedestal head may be die formed from a single piece of metal.

Claims

1. A method of locating and fastening an access floor panel to a pedestal, the access floor panel having a bottom and a top with a peripheral flange extending therefrom, the floor panel having a hole therethrough adjacent to a corner thereof, a pedestal head having a base with a threaded hole extending therethrough and an upper support, the floor panel having a receiver formed in the base thereof for engagement with a projection on the base of the pedestal head, the method comprising the steps of:

disposing the corner of said floor panel over the pedestal head so that the flange is resting on the upper support of the pedestal head and the bottom of the floor panel is spaced slightly above the base of the pedestal head;

locating the floor panel relative to the pedestal head so that the receiver is aligned with the projection;

inserting a fastener through the hole of the floor panel and said threaded hole of said base of said pedestal head; and

tightening the fastener so that the base of the pedestal head comes into contact with the bottom of the floor panel and the projection on the base of the pedestal head extends into the receiver of the floor panel while the fastener separately extends through the hole of the floor panel and said threaded hole of said base.

2. An access flooring system comprising:

a pedestal head; and

a plurality of floor panels to be supported by the pedestal head, each of the floor panels including

a floor panel top having a hole for receipt of a bolt or a screw; and

a floor panel base,

the floor panel base having a projection, said projection including a cone depending from a peripheral corner of said floor panel,

the pedestal head including

a pedestal base portion; and

a pedestal upper support portion extending from the pedestal base portion,

a threaded hole for receipt of the bolt or the screw extending through the hole of the floor panel top,

the pedestal upper support portion having a receiver,

the pedestal upper support portion having a support surface,

the receiver of the pedestal upper support portion being engagable with the projection of the floor panel base seperated from the threaded hole and an underside of a peripheral flange of the floor panel top being supported on the support surface of the pedestal support portion on mounting of the floor panel on the pedestal head.

3. The access flooring system as claimed in claim 2, wherein the pedestal head is formed from a single piece of metal.

4. The access flooring system as claimed in claim 3, wherein the pedestal head is stretch formed.

5. The access flooring system as claimed in claim 3, wherein the pedestal head is die formed.

6. The access flooring system as claimed in claim 2, wherein a length of the pedestal head between the pedestal base and the upper support portion is slightly greater than a depth of said floor panel.

7. The access flooring system as claimed in claim 6, wherein a difference between the length of the pedestal head and the depth of the floor panel is less than about 50 thousands of an inch.

8. The access flooring system as claimed in claim 2, wherein said peripheral flange extends to substantially a central longitudinal axis of the pedestal head.

9. The access flooring system as claimed in claim 2, wherein said pedestal base portion includes a threaded hole, and said floor panel includes a hole alignable with said threaded hole for coaxially receiving a fastener.

10. The access flooring system as claimed in claim 2, wherein said pedestal base portion supports a bottom of said floor panel.

11. The access flooring system as claimed in claim 2, wherein said pedestal head is disposed at an upper end of a pedestal resting on a surface.

12. The access flooring system as claimed in claim 11, wherein said pedestal includes means for adjusting a height of said pedestal head relative to said surface.
