Definitions

  • the present invention relates to a panelling system and to carriers for supporting a panelling system.
  • One type of panelling system 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 portion.
  • 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 carriers are conventionally provided with lugs, usually bent down and back parallel to the flanges in the same direction.
  • a panel is mounted with the arm being supported on one lug and the rim on the adjacent lug and the next panel is then introduced, 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 satisfactory, at least 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.
  • the lugs are made resilient and urge the panels up against the flanges of the carriers. It will be appreciated that if the panels are removed in one or two occasions to attend to wiring or plumbing or the like behind the panelling, then the lugs will become progressively weakened and experience has shown that very often they tend to snap off. This is, of course, totally unsatisfactory.
  • a general purpose carrier which may receive different panels, that is panels of a different shape and or dimensions, and which can also cope with a variety of installation requirements, such as severe fire regulations.
  • a general purpose carrier several widths and shapes of panels 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 carrier.
  • Increased fire resistance regulations, for certain kinds of installations are met by optional locking elements which may be in the form of tabs, which are to be bent behind an internal panel side portion if positive locking of such panel is desired.
  • FR-A-2484505 describes a further form of carrier which comprises an elongate body securable to 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 form one another along the length of the carrier, the lugs of each pair being spaced from one another laterally, 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 first lug.
  • a retaining element to be provided on said body and to be positionable, after the rim of one panel and the arm of an 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 to be formed by one of the lugs of an adjacent pair of lugs.
  • the first lug of a pair is rigid and the second lug of a pair is resilient and advantageously the retaining element is formed by the second or resilient lug of a pair. It is also conceivable that it could be formed by a first more rigid lug of a pair.
  • 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 suid side portion.
  • 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 other lug can abut against the side portion of the adjacent panel to hold said side portion and its associated arm in place. . .
  • the first and second lugs are formed by punching out of one or more flanges associated with said body, whereby the first lugs include a connecting portion and said tongue and are provided with a reinforcing rib whereby the second lug includes a connecting portion and a leg, the leg being positioned to hold the arm and the rim of adjacent panels in place on the tongue of the associated first lug.
  • the body comprises two flanges each of which is provided with a series of pairs of lugs.
  • the leg may have, adjacent to its free end, a shaped portion adapted to engage behind a projecting part formed on the arm of the panel to prevent rattling.
  • the invention also relates to a panelling system comprising a carrier and two panels which each have a main panel portion with an inturned side portion having, at its free edge, a rim turned towards the other side portion and the side portion having, at its free edge, an arm turned away from the one side portion, a plurality of carriers each comprising an elongate body securable to a support structure, a plurality of 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 carriers, the lugs of each pair being spaced from one another laterally, 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 the rim of adjacent panels in place on the tongue of the first lug.
  • the present invention 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 side 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 from disengaging from said space.
  • Figure 1 is a schematic perspective view showing a panel ceiling structure using a carrier according to the invention, the two panels mounted thereon and with the retaining element about to be bent in place;
  • Figure 2 is a schematic side elevation of the ceiling structure of Figure 1 with the lug forming the retaining element shown bent into place.
  • a carrier 10 which comprises a body 11 of inverted U-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.
  • the body has openings 14A, 14B to enable the carrier to be supported, openings 14C for the passage of bars to interconnect adjacent carriers and openings 14D for ease of reference in cutting a carrier to the length corresponding to that of a full panel.
  • the flanges 12 and 13 are each provided with a longitudinally extending row of lugs.
  • the lugs alternate so that they include a first type of lug 15 and a second type of lug 16.
  • Both the lugs 15 and 16 are punched out of the flanges 12 and 13.
  • the lugs 15 are rigid lugs and consist of a connecting portion 18 and a tongue 17. Both the connecting portion and tongue are reinforced by a rib 19. It will be noted that the free end 20 of the tongue is 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 Figure 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.
  • the connecting portion 22 Adjacent the junction of the connecting portion 22 with the flange 12, 13, the connecting portion 22 is provided with a hole 28. Adjacent to or at its free end the leg 24 is provided a curved projection 23.
  • the panels which the carrier supports include a main portion 30 which is substantially flat and side portions 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 is formed, adjacent its free end, the projecting part in the form of a bead 34.
  • a backturned ledge 36 At the junction of the side portions 32 with the arm 33, there is formed a backturned ledge 36.
  • the first of the panels is engaged so that its arm 33 is above one rigid lug 15 and the rim 35 is above another of the lugs 15 and the panel is moved to the right, as seen in Figure 2.
  • the next panel is then taken and its arm 33 is pushed over the rim 35 of the previously assembled panel and so that its bead 34 engages the leg of the lug 16 there- above.
  • the leg being somewhat longer than the tongue, is resilient and flexed upwardly until the bead 34 has moved beyond the projection 23 which then snaps down behind the bead.
  • the rim 35 engages behind the next tongue 17.
  • the panelling system is built up successively.in this way.
  • the curved down end portion 20 facilitates the introduction of the arm 33 and of the rim 35.
  • the pitch of the panels is such that they are greater than the pitch and, as shown, equal to two or more pitches between adjacent sets of lugs 15, 16.
  • the lugs 15, 16 of the right hand pair are used to support the left side of the right panel 30 and the right side of the left panel 30 and the left hand of the lugs 15 shown in Figure 2 is not used at all, but rather the left hand panel 30 is supported at its free end by another pair of lugs 15, 16 (not shown).
  • a screwdriver is inserted, as shown in Figure 1, into the hole 28 and is rotated slightly as shown by the arrow in Figure 1, so that the left hand of the lugs 16 illustrated in Figure 2 is bent down so that it extends in a substantially vertical plane, that is somewhat under the associated rigid first lug 15 of that pair.
  • the retaining element 27 can abut against the side portion 32 to prevent the side portion from moving to the left, thereby retaining the panels in position even though they may be subjected to wind or to buckling from overheating for example as a result of fire. Rattling of the panels is also reduced by the ledge 36 engaging in the notch 29 above retaining element 27.
  • the construction of the carrier according to the present invention makes it suitable for use with various panels of different panel width. It also reduces the overall cost of the carrier due to its general simplicity.
  • the locking option which is available due to forming the retaining elements 27 integrally with either the lug 16, as shown, or with the lug 15, is 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 retaining facility would then not be available.
  • the carrier 10 has been shown as having two flanges 12, 13, the invention also 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.
  • the body could then be of inverted U- or V-cross-section, with the lugs formed in the lower edges of the inverted U- or V-cross-section body.
