Description
~7~
The present invention relates to a panelling system and to carriers for suppor~ing a panelling system.
One type of panelling sys~em has panels which are each formed with a main, substantially flat, panel portion, which has an inturned side portion on each of two opposite sides. One of these side portions has, at its free edge, a rim which is turned inwards and the other side portion has, at its free edge, an arm which is turned away from the one side portionv These panels are conventionally mounted on carriers which themselves are mounted on a wall or ceiling structure to be clad by the panelling. The flanges of the ca~riers are convention~lly provided with lugs, usually bent down and back parallel to the flanges in the same direction. A panel is mounted with the arm being ~upported on one lug and the rim on the adjacent lug and the next panel is then introauced, so that its arm engages above the rim of the already fitted panel and abuts against the flange, the rim and arm being urged upwardly by the resilience of the lug. This arrangement is generally ~atisfactory, at lea~t in the short term, in that it provides a pleasant appearance to the panelling, the arm in each case bridging the gap between the main panel portions, so that the carriers cannot be seen.
Various problems arise with this construction, ~irstlyr in order to ensure that the panels are held ,.
~ ''`".

~7~
firmly, the lugs ~re made resilient and urge the panels up against the flanges of the carriers~ It will be appreciated that if the panels are removed on one or two occasions to attend to wiring or plumbing or the like behind the panelling, then the lugs will become progressively weakened and ~xperience has shown that very often they tend to snap offl This is) of course, totally unsatisfactory.
An example of such a system is illustrated in lQ GB-2118988A r In this arrangement, a general purpose carrier is provided which may receive different panels, that is panels of a different shape and o dimensions, and which can also cope with a variety of installation requirements, such as severe fire regulations~ To achieve this general purpose carrier, several widths and shapes of pan21s are available to cooperate with one type of carrier, often in the form of single and multiple pitch panels spanning one or more sets of lugs based at regular intervals along the ~arrier. Increased fire resistance regulations, for ~ertain kinds of installation~ are met by optional locking elements which may be in the form of tabs, which are to be bent behind an intérnal panel side portion if positive locking of sush panel i~ desired.
~lthough such further provisions render a ~5 certain carrier more generally usable and obviate the need ;~ , for further types of earriers, ~hey also account for increased costs and decreased stability of the assembly.
In general, therefore~ such carriers may be considered to comprise an elongate body securable ~o a support structure; a plurality of lugs on said body, the lugs being arranged in at least one series of pairs, the pairs of lugs of the or each series being spaced from one another along the length of the carrier, the first lug of each pair being substantially rigid and including a tongue spaced from the adjacent body portion to accommodate in the thus formed space the rim of one panel and the arm of an adjacent panel, the second lug of a pair being adapted to hold the arm and rim of adjacent panels in place on the tongue of the Pirst lug.
lS In order to overcome the problem o~ increased cost and decreased stability of such device, it is now proposed, according to the present invention, for a retaining element to be provided on said body and to be posltionable, a~ter the rim of one panel and the arm of an : 20 adjacent: panel have been inserted in said space, behind the other portion of said adjacent panel to prevent the arm from disengaging from the space and for the retaining element ~o be formed by one of the lugs of an adjacent pair of lugsO Usually the first lug o~ a pair is rigid and the second lug of a pair is resilient and advantageously the retaining element is ormed by the second or resilient lug of a pair. It is al50 conceivable ~hat i~ could be formed by a first more rigid lug of a pair.
With such a construction the total cost can be significantly reduced while providing the nece~sary flexibility of operation.
Advantageously the lug forming the retaining element is provided with a hole into which may be inserted a screwdriver or similar tool by means of which said lug may be bent to extend in a plane different from that in which it would normally extend to cooperate with the other lug of the pair, so that, when so bent, said retaining element can engage behind said side portion,- Thus, the second lug which is not being used as part of a pair of lugs to support a panel? can readily be bent, usually downwardly, so that the retaining element surface of this second or o~her lug can abut against the s1de portion of the adjacent p~nel to hold said side por~ion and its associated arm in place.
Preferably the fir~t and second lugs are formed by punching out o~ one or more flanges associa~ed with said body, whereby the first~lugs înclude a connecting portion and said tongue and are provided with a reinforcing rib whereby the second lug includes a connecting portiQn and a leg, the leg being positioned to hold the arm and the rim oP adjacent panels .~.

in place on the tongue of the associated first lug.
Desirably the body comprises two flan~es each of which is provided with a series of pairs of lugs.
The leg may have, ad j aren'c to its f ree end, a 5 shaped portion adapted to engase behind a projecting part formed on 'che arm of the panel to prevent rattling, The invention also relates to a panelling sys'cem comprising panels which each have a main panel portion with an inturned side portion having, at it~ ree edge, 10 rim turned ~owards the other side portion and the side portion having, at its free edge, an arm turned away from the one side portion, a plurality o~ carriers each ~ompri~ing an elongate body securable to a support structure, a plurality of lugs being arranged in at least 15 one series of pairs, the pairs of lugs of the or eacll serie~ being spa ::ed from one another along the length of the carrier, the first luy o each pair being substantially rigid and including a tongue spaced from the adjacent body portion to accommodate in the 'chus formed 20 space ~he rim of one panel and the arm of an adjacent panel, the second lug of a pair being adapted to hold the arm and the rim of adjacent panels in p;lace on the tongue of the first lug.
According to this aspect~ the present invention ':, ', > ~ ~
l~lb proposes a retaining element is provided on said body and is positionable, after at least the arm of an adjacent panel have been entered in said space behind the other sids portion of said adjacent panel to prevent the arm from disengaging from the space and the width of the panels between side portions is greater than the pitch between the pairs of lugs, and the retaining element is formed by one of the lugs of an adjacent pair of lugs to that pair which is holding at least the arm of an adjacent panel, whereby the retaining element on one of the lugs of a pair which is intermediate where the pairs of lugs supporting the panel, can engage behind the side portion, to prevent the arm of that panel rom disengaging from said space.
In order that the present invention may more readily be understood, the following description .is given, merely by way of example, reference being made to the accompanying drawings in which:-Figure 1 is a schematic perspective view showing a panel ceiling structure using a carrier according to the invention, with two panels mounted thereon and with the retaining element about to be b~nt in place; and Figure 2 is a schematic side elevation of the ceiling structure of Figuee 1 with the lug forming ~he retaining element shown bent into placP.
Referring ~o the drawings, there is illustrated . ~
i7~i.3L
a carrier 10 which comprises a body 11 of inverted ~ shaped cross section provided with two side flanges 12 ; and 13 which extend outwardly away from one another from the free ends of the U~shaped cross-section body. As can be seen more c1early in Figure 1, the body has openings 14A, 14B to enable the carrier to be supported, openings 14C for the passage of bar~ to inter~onnect adjacent carriers and openings 14D for ease of reference in cut~ing a carrier to he length corresponding to that of a full panel.
The flanges 12 and 13 are each provided with ~
longitudinally extending row of lugs, The lugs alternate so that they iw lude a first type of lug 15 and a ~econd type of lug 16.
Both the lugs 15 and 16 are punched out of the flanges 12 and 13. rhe lugs 15 are rigid lug~ and consist of a connecting portion 18 and a tongue 17. Both the connecting portion and tongue are reinforced by a rib 19.
It wil7 be noted that the free end 20 of the tongue is : 20 bent down to provide a curved end portion extending away from the flange 12, 13.
The lugs 16 have a connecting portion 22 and an elongate leg 24 having a reinforcing rib 25. On the right as seen in Flgure 2, the lug 16 forms a retaining element 27. As shown, the retaining element 27 is defined by a notch 29 removed from the right side of lug 16. It is . ~ ~
,, ~ . ................ .
' contemplated, however, that the notch could be omitted and the right hand side of the lug 16 could be straight and this straight side then form the retaining element.
. _ Adjaeent the junction of the connectiny portion 22 with the flange 12, 13, the connecting portion 22 is provided with a hole 2&. Adjacent to or at its free end the leg 24 is provided a curved projection 23.
As shown in Figure 1, the panels which the carrier supports include a main portion 30 which is substantially flat and side port~ons 31 and 32. One side portion 31 has an inturned rim 35. The other side portion 32 is provided with an arm 33 which extends away from the side portion 31 and i5 formed, adjacent its free end, the projecting part in the form of a bead 34. At the junction of the side portions 32 with the arm 33, there is formed a backturned ledge 360 In o~der to mount the panels on the carrier, the first of the pan~l~ is engaged so that its arm 33 is above one rigid lug lS and the rim 35 is above another of the lugs 15 and the panel is moved to the right, as s en in Figure 2. The nex~ panel is then taken and its arm 33 is pushed over the rim 3~ of the previously assembled panel and so that its bead 35 engages the leg of the lug 1 : thereabove. The leg, being somewhat longer than the tongue, is resilient and flexed upwardly until the bead 34 ha~ moved beyond the projection 23 which then snaps down : -`
~ , ''.
~ 7~
behind the beadO At ~he same ~ime, the rim 35 engages behind the ne~t tonyue 18. The panelling system is built up ~ucces~ively in this way.
The curved down end portion 20 facilitates the introduction of the arm 33 and of the rim 35.
It will be appreciated that the pitch of the panels is suoh that they are greater than the pitch an~, as shown, egual to two or more pitches between adjacent sets o lugs 15, 16~ As can be seen, for example, in Figure 2, the lug~ 15, 16 of the right hand pair are used to support the left side of ~he right panel 30 and the right side of the left panel 30 and the left hand of the lugs 15 shown in Figur~ 2 is not used a~ all, but rather the left hand panel 30 is supported at its free end by another pair of lugs lS, 16 (not shown)~ ~ow in order to hold the assembled panels in place, a scre~driver is inserted, as ~hown in Pigure 1, into the hole 28 and is rotated sIi~htly as shown by the arrow in ~igure 1, so that the left hand of the lugs 16 illustrated in Figure 2 is bent down so that it exten~s in a substantially vertical plane, that is somewhat under the associated rigid first lug 15 of that pair. In this position, the retaining element 27 can abut agai~st the side portion 32 to prevent the side portion from moving to the left, thereby retainin~ the panels in position even thcu~h they may be subjected to wind or to buckling from overheating "~
':
~7~
for example às a result of fire. Rattling o the panels is also reduced by the ledge 36 engaging in the notch 29 above retaining elemen~ 27.
It will be seen ~hat further tabs 40 of S trapezium cross-section are al~o provided bent down slightly from ~he associated flange 12g 13 and these limit the move~ent o~ the panel arm towards ~he sarrier body under wind load~ The additional tab 42 which remains has no function and i5 only let remaining as a result of punching out from the ori~inal flange 12, 13.
The construction of the carrier accordiny to the present invention makes it suitable for use with various panels of different panel width. It ~lso redu~es the overall cost of the carrier due to its general simplicity~
15 The locking option which is available due to forming the retaining elements 27 integrally with eikher the lug 16, as shown, or with the lug 15, i~ only available for panels having a width spanning a multiple pitch. However, other panels having the same pitch as the pitch between the lugs, can be mounted but the locking or ret~ining facility would then no~ be availableO
: While the carrier 10 has been shown as having two flanges 12, 13, the invention al~o contemplates the use of only one flange, with the carrier body 10 of-L- or other cross-section, as well as the carrier body having no flanges at all~ For example, the body could then be of `:

Both the lugs 15 and 16 are punched out of the flanges 12 and 13. rhe lugs 15 are rigid lug~ and consist of a connecting portion 18 and a tongue 17. Both the connecting portion and tongue are reinforced by a rib 19.
It wil7 be noted that the free end 20 of the tongue is : 20 bent down to provide a curved end portion extending away from the flange 12, 13.
The lugs 16 have a connecting portion 22 and an elongate leg 24 having a reinforcing rib 25. On the right as seen in Flgure 2, the lug 16 forms a retaining element 27. As shown, the retaining element 27 is defined by a notch 29 removed from the right side of lug 16. It is . ~ ~
