The panels form a panel system with adjacent edges having longitudinally running connectors facilitating connection of adjacent edges of adjacent panels by relative sliding in the longitudinal direction of the adjacently arranged edges. The panel system includes a panel support, the panel and support being configured for releasable connection to the one another by an interlocking connection in which limited relative movement of the support across the face of the panel is permitted between a release orientation, in which connection and separation of the panel and support is facilitated, and an interlocked orientation in which separation of the panel and support is restricted.

Description

Panel and Panel System
The present invention relates to a panel and panel system, particularly to a panel and panel system for use in staging, decking, or display applications such as in constructing staging, exhibition platforms or set design.
Decking panel systems for use in providing elevated staging systems are known and for example disclosed in EP- A-0851073. Another such system comprises an expandable aluminium support riser framework (disclosed in EP-A- 0884425) over which is laid steel or aluminium framed plywood decking panels. The decking panels of the system are heavy and cumbersome. Furthermore, the interconnection arrangement (including connection pegs) permitting connection of adjacent panels is relatively inflexible permitting matching panels to be connected coextensive edge to co-extensive edge. Furthermore, connection is facilitated at panel corners only, such that there exists no solid coupling along the majority of the length of the edge to edge panel interface. Differential loading of adjacent panels tends to cause relative displacement and separation of panel edges at the edge to edge interface of adjacently laid panels.

The edge element preferably includes a respective flange portion arranged to abut the terminal edge of one (or more preferably both) of the spaced first and second layers.
The edge portion preferably includes a connection formation permitting connection of complementary edge portions provided on adjacently arranged panels, thereby permitting edge to edge connection of panels in a connected panel/decking system. The connection formation preferably comprises a longitudinally running formation
(for example a groove or recess) arranged to locate with a transverse marginal portion of a longitudinally running connection element, the other transverse marginal portion of the connection element being arranged to locate with a complementary connection formation provided for the edge element of an adjacently laid panel.
The connection element is preferably arranged -to slidingly engage with the edge elements of adjacent panels, with marginal portions of the connection element subsequently being held captive relative to respective edge elements of adjacently laid panels, inhibiting separation of said panels .
The connection element is preferably of a material providmg a degree of rigidity (particularly m the direction transverse to the longitudinal edge direction.
In a preferred embodiment, the connection element is configured to include transverse marginal portions of greater thickness than a web portion connecting the marginal portions. The increased thickness marginal portions are preferably received m respective slot formations m respective panel edge elements, which slot formations include a relatively narrower mouth opening to a relatively larger marginal portion receiving recess. The respective slot formations preferably run substantially along the entire longitudinal extent of the respective panel edge element, and are preferably open proximate at least one (preferably both) longitudinal ends of the slot m order to permit sliding insertion of the connection element. It is believed that such an arrangement is novel and inventive per se.
According to a second aspect, the invention provides a panel system comprising a plurality of panels arranged m edge to edge adjacent relationship, adjacent edges being provided with a respective longitudinally running connection formation facilitating connection o-f adjacently arranged edges of ad acent panels by relative sliding m the longitudinal direction of the adjacently arranged edges causing mating of a connection element with a panel edge connecting formation.
Desirably, preferred features of the edge connection are as described above m relation to the first aspect of the invent ion .
The panel system is preferably provided with support means arranged to be positioned beneath the decking panels in order to support the panels in an elevated position.
Each decking panel is preferably provided with a respective support module arranged to underlie a respective panel . The support modules may comprise collapsible support frame modules (as known in the art) which are expandable from a collapsed configuration to an expanded configuration in order to underlie substantially the entire area of a respective panel.
Desirably the decking panel according to the invention is provided with location means to locate the support means in position. The location means is preferably provided on the underside of the panel, preferably proximate the edge of the respective panel .
The feature described above of the edge element of the panel fitting in a recess defined by the edge of the body layer and one or both of the first and second layers permits the location means for the support -means to be positioned extremely close to the edge of the panel. This has advantages in minimising the degree of possible deflection at the adjacently arranged edges due to panel loading. A preferred embodiment of support and panel connection is defined below. According to a further aspect the invention provides a panel system comprising a panel and a support for the panel, the panel and support being configured for releasable connection to one another by means of an interlocking connection in which limited relative movement of the support across the face of the panel is permitted between a release orientation, in which connection and separation of the panel and support is facilitated, and an interlocked orientation in which separation of the panel and support is restricted.
Desirably the panel and support are guided in relative movement between the release and interlocked positions, preferably by guide formations carried by the support and/or panel.
It is preferred that the relative movement of the support and panel between the release orientation and the interlocked orientation is substantially translational movement .
It is preferred that the relative movement of the support and panel between the release orientation and the interlocked orientation is substantially relative sliding movement .
The interlocking connection inhibits separation of the support from the panel in a direction transverse to the plane of the panel when the panel and support are orientated in the interlocked orientation. Sliding the support to the release orientation relative to the panel permits separation of the support from the panel in a direction transverse to the plane of the panel.
The interlocking connection between the panel and the support as defined permits convenient and rapid assembly/disassembly of panel systems according to the invention.
It is preferred that the interlocking connection includes a captive portion (preferably comprising the support) and a capture portion (preferably comprising the panel), the capture portion being arranged to retain the captive portion when the panel and support are orientated in the interlocked orientation. The captive portion preferably comprises a head portion arranged to be slidably received in the capture portion.
The capture portion preferably includes a mouth aperture or recess into which the captive portion may be introduced (and out of which the captive portion may be withdrawn) , and a detent portion having detent formations arranged to lie adjacent the captive portion and inhibit separation of the panel and support. The detent portion preferably comprises a slot or channel communicating with the mouth aperture or recess of the capture portion. In the interlocked orientation a neck portion of the support (preferably connected to the head portion) desirably extends through the slot or channel.
It is preferred that the interlocking connection is facilitated proximate the edge of the panel, preferably proximate a corner of the panel . Desirably interlocking connection between panel and support is facilitated proximate a plurality of corners of the panel. Where the panel s substantially square or rectangular m configuration, an interlocking connection between support and panel is facilitated at each corner of the panel.
The support preferably comprises a support limb, preferably provided with a bolster element arranged to be positioned adjacent the face of the panel when the support limb is connected to the panel. The bolster element typically supports the panel where the panel is utilised m load bearing applications. The bolster element is preferably arranged to be positioned about the interlocking connection. The bolster element and panel are preferably provided with complementary engageable formations to ensure location of the interlocking connection particularly, preferably, m the interlocked orientation.
Desirably, the support comprises an expandible/collapsible framework including a plurality of support limbs arranged to be spaced when the framework is m expanded configuration. Desirably a plurality of 1-ιmbs m the expandible framework are configured to provide the interlocking connection with the panel.
In a preferred embodiment the interlocking connection comprises :
male captive head carried by the support; and, a female capture recess provided for the panel, the recess including a mouth portion into which the captive head may be introduced and a slot portion adjacent to and communicating with the mouth portion, the slot portion being configured to retain the captive head against separation from the panel in a direction transverse to the plane of the panel.
The panel system can be utilised in situations where the panel is load bearing (where the panel will rest on the support interlocked with the support) or where the panel is suspended from the support. Additionally the panels may be oriented vertically. The interlocking connection which is the subject of the invention permits such a wide variety of arrangements to be utilised. Prior art arrangements (such as the arrangement disclosed in EP-A-
0884425) are suitable for use as panel bearing supports only. Furthermore there is a danger of the panels slipping out of alignment with the underlaying support which can result in destabilisation of a supported panel system.
The panel system having interlocking connection between the support and panel has particular advantage in providing rapid assembly/disassembly for supported panel systems. Synergy is provided in using such a feature with the earlier defined aspects of the invention in providing well supported, lightweight edge connected supported panel systems. It is therefore preferred that the panels and edge connection aspects of earlier defined aspects are utilised in combination with the interlocking support/panel aspect of the invention.
The invention will now be further described, by way of example only, m specific embodiments and with reference to the accompanying drawings, m which:
Figure 1 is a schematic sectional view of panels comprising a panel system according to the invention;
Figure 2 is a perspective view of the panel system of figure 1 m assembly;
Figure 3 is a schematic view of a panel/support connection arrangement according to the invention;
Figure 4 is a plan view of a panel side portion of the connection shown m figure 3 ;
Figure 5 is a perspective view of an alternative embodiment of a connector element useable m a panel system according to the invention; and,
Figures 5 and 6 are side and perspective views (corresponding to figures 1 and 2) of the panel system utilising the connector element of figure 5.
Referring to the drawings and initially to figures 1 and
2 m particular, there is shown a staging system
(generally designated 1) comprising a pair of substantially identical rectangular decking panels 2, 3 connected along a marginal edge interface 4. Each decking panel 2, 3 comprises respective upper and lower plywood panel skins 5, 6 spaced by an intermediate cellular body layer 7 of honeycomb (hexagonal) shaped cells in extruded polypropylene. The cell axes of the hexagonal cells comprising the integrally formed cellular layer 7 extend in the direction of spacing of the plywood panel layers 5, 6.
Respective sheets 8 of flexible absorbent material are bonded over opposed upper and lower extents of cellular body layer 7. During manufacture of the decking panels 2, 3, the sheets 8 have curable bonding material applied before plywood panels 5, 6 are pressure bonded to the upper and lower extents of the intermediate honeycomb cellular body layer 7.
As will be seen from the drawings, the marginal portions of plywood panels 5, 6 extend beyond the extent of the intermediate cellular body layer 7, defining a revetment or recess within which a stem portion 9 of a respective elongate plastics edge element 10 is received. Each elongate edge element 10 is formed of extruded rigid plastics material and includes a flange portion extending outwardly from the stem 9 and terminating at *a surface at a level with the respective outer surface of plywood panels 5, 6. The outer edges of respective edge elements 10, abut one another at interface 4.
Each elongate edge element 10 includes a longitudinally running central channel 11 spaced from the outer edge surface of edge element 10, and communicating therewith ia a narrow slot or mouth 12.
The stem portion 9 of respective edge elements 10 is bonded along upper and lower surfaces to respective plywood panels 5, 6, and along its transverse edge to the upwardly extending edge of honeycomb cellular structure body layer 7.
The "composite" construction of the panel results in a lightweight panel with high modulus of rigidity. When a respective panel 2,3 is loaded bending moments are set up in the composite 'sandwich' panel which resolve into shear forces on the plywood panel skins 5,6. The shear forces are transferred via the bonded connection to the cellular body layer 7 and resolved at the terminal edges of the panel by the elongate edge elements 10 which are bonded to the marginal portions and edges 15 of panels 5. The periphery of the decking panel is typically entirely bounded by such bonded edge elements.
Respective panels 2, 3 are connected at the edge interface 4 by means of an elongate extruded plastics connection element 13 comprising a relatively narrow web portion 14 interconnecting spaced thickened (bulbous) marginal portions 15. Bulbous marginal portions 15 are received in the respective channels 11 in adjacent edge elements 10, the web portion 14 spanning the edge interface 4 extending through slots 12.
In use, the respective edge elements 10 of panels are arranged adjacent one another. The bulbous marginal portions 15 of the connection element 13 are then inserted via an open end of respective channels 11 and slide in the channels 11 in the longitudinal direction of the respective edge elements 10. The connection element 13 is of sufficient rigidity to ensure that relative loading of one panel (causing deflection of that panel) causes corresponding deflection of the edge connected panel and results in a substantial avoidance of trip edges. The deflectional load of one panel is transmitted via the connection element 13 so as to be distributed partially to the connected panel .
The embodiment of connection element 113 shown in figures 5 to 7 comprises an elongate metallic element having upturned marginal portions 115 and an interconnecting spanning portion 114 comprising upwardly inclined spanning portions meeting at a common longitudinally running crest - line 201. The arrangement shown enables the element to flex in a spring-like manner (to a small degree) about the crest-line 201, thereby permitting slight deflection of the upturned marginal portions 115. As shown in figure 6, when the connector element 113 is in position with marginal portions 115 received in respective channels 11, the marginal portions 115 act to prevent separation of the longitudinally joined edges of the adjacent panels 2,3. Flat surface disc portions 202,203 aid in the secure location and alignment of panel edges 10 and also inhibit the release of marginal portions 115 from respective channels 11.
An important feature of the edge elements is that the stem portion 9 is matched m thickness to the thickness of the body layer 7. This ensures secure bonding of the edge element to the plywood panels 5, 6. The edge element has flange return 15 to which the terminal edges of plywood panels 5, 6 are bonded; the return 15 further protects the terminal edges of the plywood skin panels from damage.
The nature and configuration of the slots 11 and connecting element 13 are such that the system enables connection of panels which are not entirely co-extensive (and differently shaped panels) providing portions of adjacent panel edges are co-extensive . Furthermore connection of adjacent panels is effectively continuous along co-extensive edge portions. Differential deflection of adjacent panel edges is therefore substantially ameliorated.
The edge element and connection element enables other structural features to be connected to panels so configured. Such features may comprise kick-edges, walls, stairs, and guard rails.
The decking panels 2,3 are typically supported m an elevated position on riser structures, which may comprise expandable riser arrangements as known m the prior art from, for example EP-A-0884425.
In a preferred embodiment and m accordance with a further aspect of the invention, panels 2/3 are provided with female receiving recesses 20 arranged to receive and retain captive a male head 21 provided on support limb 22. Support limb 22 may, for example, comprise an edge limb of a riser arrangement as disclosed m EP-A-0884425.
The female recess 20 is defined through a circular metallic plate 23 which is partially sunk into the surface of panel skin 6 and secured to the panel skin 6 (typically by screws 30) . The recess 20 is defined by a shaped aperture m plate 23 comprising a circular mouth aperture portion 24 and a slot aperture portion 25 extending away from mouth aperture portion 24 and of a width less than the diameter of mouth aperture portion 24. The aperture m plate 23 is consequently 'key hole' shaped m appearance .
Adjacent plate 23 a recessed slot 26 is formed m the skin 6 of panel 2/3 the slot having a width corresponding to the diameter of mouth aperture portion 24. The dimensions of mouth aperture portion 24 and slots 25, 26 are selected such that a terminal flange of 27 of male head 21 is msertable via mouth aperture portion 24 to be received m recess 26 m skin 6. The limb 22 is then moved sideways
(m the direction of arrow A m figure 3) causing flange portion 27 of head 21 to slide in slot 26 such that the flange portion is held captive by the edges .of the slot aperture portion 25 of the plate 23. Neck portion 33 extends through the slot aperture portion 25 of the plate 23. In such a condition the limb 22 cannot be separated from interlocking engagement with panel 6 by simple movement perpendicular to the plane of panel 2/3. It is necessary to purposefully slide limb 22 relative to panel 2/3 m the reverse direction (opposed to arrow A m figure 3) in order to enable the limb 22 to be separated from panel 2/3.
Limb 22 carries a bolster element 29 which in use engages with plate 23 and provides a bearing surface, particularly where panel 2/3 is used in load bearing applications. Plate 23 is provided with projections (typically the heads of screws 30 securing plate 23 to skin 6) . Projections 30 mate with corresponding recesses 31 provided on the upper surface of bolster element 29 to ensure accurate location of limb 22 with the female capture recess 20 when in the interlocked position.
In view of the fact that the edge elements are flush with the plywood skin 6 underside, the riser locators (female sockets 20 may be positioned close to the panel interface 4. This aids in minimising the differential deflection of adjacent panels due to differential loading.
Whilst described primarily in relation to load bearing panel systems, the invention is also suited to, and makes possible the use of supported suspended panels and also the use of panels supported in a vertical orientation. Such adaptability makes the panel system of the invention particularly useful for constructing temporary display structures and the like. The panel system having interlocking connection between the support and panel has particular advantage in providing rapid assembly/disassembly for supported panel systems. Synergy is provided in using such a feature in combination with a composite, edge connected panel arrangement in providing well supported, lightweight edge connected supported panel systems .
