Description

ACCESS FLOORING SYSTEM, PEDESTAL AND PEDESTAL CAP THEREFOR
Introduction
The invention relates to access flooring systems of the type comprising a plurality of floor panels and a plurality of support pedestals for supporting the floor panels. Such flooring systems are used to define an underfloor chamber through which various conduits and wiring can be led, for example for various electrical or computer services and/or for conduits of an air conditioning system. The pedestals are distributed over a subfloor, such as a floor of a multi-storey building and they are arranged to support the floor panels such that floor panels can be individually removable to gain access to the chamber below the panels. When assembled, the panels provide a relatively flat and strong floor to support office personnel and furniture.
The current method of locating a floor panel onto a supporting pedestal is to use a plastic moulded pedestal cap, which has at its centre a cruciform moulded feature intended to help locate the panel during the laying process. This cruciform also helps reduce the phenomenon known as windowing at the junction of four panels by maintaining each panel square to panels adjacent to it.
There is a potential problem of floor panels contacting adjacent ones and whilst being walked upon causing a noise to be created in the form of a metallic squeak. The problem is exacerbated by small particles of grit which gravitate between the joints.
There is therefore a need for an improved access flooring system which address this problem. Statements of Invention
According to the invention there is provided an access flooring system comprising a plurality of floor panels and a plurality of support pedestals for supporting the floor panels, the pedestal having a spigot projection extending upwardly therefrom and the underside of the panels at the corners thereof having an indent complementary to the spigot projection, the spigot projection engaging with the underside panel indent, on assembly, to control the gap between adjacent panels, wherein the spigot projection extends radially of a longitudinal axis of the pedestal.
In one embodiment the pedestal has a number of spigot projections which are spaced-apart around the top of the pedestal.
In another embodiment there are four spigot projections which are equi-spaced apart around the top of the pedestal.
In a further embodiment the pedestal has a cap and the spigot projection is provided by the cap.
In one embodiment the floor panel comprises an envelope encapsulating a core and the indent is formed in the underside of the envelope.
In another embodiment at least the underside of the envelope is of metal and the indent is formed in the metal.
In a further embodiment the indent is formed after encapsulating the substrate in the envelope.
According to another aspect of the invention there is provided a pedestal for an access flooring system, the pedestal having a spigot projection extending upwardly therefrom for engagement in an indent complimentary to the spigot projection in the underside of a flooring panel, wherein the spigot projection extends radially of a longitudinal axis of the pedestal.
In one embodiment the pedestal has a number of spigot projections which are spaced-apart around the top of the pedestal.
In another embodiment there are four spigot projections which are equi-spaced apart around the top of the pedestal.
In a further embodiment the pedestal has a cap and the spigot projection is provided by the cap.
According to a further aspect of the invention there is provided a pedestal cap for an access flooring system, the pedestal cap having a spigot projection extending upwardly therefrom for engagement in an indent complementary to the spigot projection in the underside of a flooring panel, wherein the spigot projection extends radially of a longitudinal axis of the pedestal cap.
In one embodiment the pedestal cap has a number of spigot projections which are spaced-apart around the top of the pedestal cap.
In another embodiment there are four spigot projections which are equi-spaced apart around the top of the pedestal cap.
Brief Description of the Drawings The invention will be more clearly understood from the following description thereof given by way of example only with reference to the accompanying drawings, in which:-
Fig. 1 is a perspective view of a pedestal cap according to the invention;
Fig. 2 is a top plan view of the cap of Fig. 1; Fig. 3 is a perspective view of the underside of the cap of Figs. 1 and 2;
Fig. 4 is a plan view of the underside of the cap of Figs. 1 and 2;
Fig. 5 is a side view of the cap of Figs. 1 and 2;
Fig. 6 is a plan view of the underside of a floor panel;
Fig. 7 is an enlarged schematic cross sectional view of the floor panel of Fig. 6;
Fig. 8 is an enlarged schematic cross sectional view of the pedestal cap of Figs. 1 and 2;
Fig. 9 is a cross sectional view of adjacent floor panels and pedestal cap, on installation; and
Fig. 10 is a schematic perspective view of an access floor system of the invention. Detailed Description
Referring to the drawings there are illustrated various elements of an access flooring system of the invention comprising a plurality of floor panels 1 and a plurality of support pedestals 2 for supporting the floor panels 1. Each pedestal 2 has a pedestal cap 3 as illustrated in Figs. 1 to 5. The cap 3 has at least one and in this case four equi-spaced apart radially extending spigot projections 5. The underside 6 of the panels have an indent 10, in this case at each of the four corners 7. The indents 10 are of complementary shape and size to the spigot projections 5 and, on assembly, a corner indent 10 of a floor panel 1 engages with a spigot projection 5 as illustrated in
Figs. 7, 8 and 9. In this way, the gap between adjacent panels is controlled and inter- panel contact is prevented.
In more detail, and referring to Fig. 7 a panel 1 comprises a central core or substrate 20 which may be of chipboard or the like, and an envelope enclosing the core 20.
The envelope may comprise a lower tray part 21 and an upper flooring surface lid part 22. The parts 21, 22 may be separately formed, for example from metal sheets and may be folded together (not shown) at a joint therebetween on enveloping of the core 20. The core 20 may be adhesively bonded to the upper and/or lower parts 21, 22. The indents 10 are formed in the lower panel part 21 by pressing a tool into the metal. Each indent 10 is accurately positioned with respect to the top edge of the panel such that it is pressed in during the panel encapsulation process. The indents
10 are preferably formed in the panel whilst the adhesive is uncured to enhance the structural strength of the panel at the corners.
The indents 10 are elongate in form and are tapered to minimise potential tearing of the metal in the region of the indent. By keeping deformation within the plastic limit of the metal, potential engagement of the indent with the core is also maximised.
Thus, the invention provides positive locations on the underside of the panels which are datumed from the upper edge of the panel. In combination with the pedestal projections 10, the engagement of adjacent panels with the associated pedestal is accurately controlled to thereby control the gap between adjacent panels and avoid adjacent panels touching. This minimises the risk of squeaking or grinding noises at the joints between panels when personnel walk over the panels.
The invention is not limited to the embodiments hereinbefore described which may be varied in detail.
