A cross rail to which one or more battens of a suspended ceiling system can be secured, the cross rail comprising an elongate channel having an upper wall via which one or more ceiling suspension clips are engageable to support the cross rail; opposed lateral walls extending downwardly from the upper wall; and pairs of opposed latching members via which one or more battens are securable to the cross rail, each latching member of a pair extending downwardly from a respective lateral wall such that, in use, a batten is securable substantially perpendicularly to the cross rail between two adjacent pairs of opposed latching members.
Description
- The present patent specification discloses a cross rail for use in a suspended ceiling system.
- In assembling suspended ceiling systems, cross rails (also referred to as top cross rails) are used to interconnect ceiling suspension clips and battens. In particular, the cross rail is supported from one or more ceiling suspension clips, and in turn, one or more battens are secured to and supported by one or more cross rails.
- Certain prior art cross rails are configured such that battens are securable thereto via an intermediate member. In one example, an additional clipping member must first be secured across an upper end of the elongate batten, and then the clipping member is itself inserted into the channel of the cross rail. This arrangement involves additional components and thus complexity and labour; provides an interconnection between the cross rail and batten that may not be able to withstand higher ceiling loads, particularly if seismic activity is to be considered; and positional adjustments of the batten relative to the cross rail can be cumbersome, particularly after the clipping member is already secured to the batten and inserted into the cross rail.
- There is a need to address the above, and/or at least provide a useful alternative.
- According to a first aspect of the present invention, there is provided a cross rail to which one or more battens of a suspended ceiling system can be secured, the cross rail comprising:
-
- an elongate channel having an upper wall via which one or more ceiling suspension clips are engageable to support the cross rail;
- opposed lateral walls extending downwardly from the upper wall; and
- pairs of opposed latching members via which one or more battens are securable to the cross rail, each latching member of a pair extending downwardly from a respective lateral wall such that, in use, a batten is securable substantially perpendicularly to the cross rail between two adjacent pairs of opposed latching members.
- In embodiments of the cross rail, the latching members project downwardly from the lateral walls. For example, adjacent latching members may be spaced apart from one another along a length of the lateral walls, which spacing is shaped and sized to receive at least an upper end of the batten. In certain embodiments, each latching member comprises one or more teeth configured for latching to a corresponding flange of the batten.
- In embodiments of the cross rail, the upper wall comprises apertures for reception of a respective ceiling suspension clip such that the cross rail can be hung therefrom. Each aperture may comprise a slit configured to receive an engagement end of the suspension clip. In certain embodiments, each aperture may further comprise a central opening extending through the slit to permit rotation of the suspension clip about a longitudinal direction thereof relative to the cross rail.
- In embodiments of the cross rail, the upper wall further comprises one or more openings associated with a respective aperture, each opening being configured to locate a corresponding projection of the suspension clip when inserted so as to retain an orientation of the cross rail relative to the suspension clip(s) from which it depends.
- The present cross rail may be integrally formed. In one example, the cross rail may be formed from galvanised steel.
- According to a second aspect of the present invention, there is provided a suspended ceiling system formed from:
-
- suspension rods;
- ceiling suspension clips secured to respective suspension rods;
- cross rails according to a first aspect of the present invention, the cross rails hanging from the suspension clips and being spaced apart in a transverse direction; and
- battens spanning across and being secured to two or more adjacent and spaced apart cross rails.
- According to a third aspect of the present invention, there is provided a method of securing a batten to a cross rail according to a first aspect of the present invention, the batten comprising an elongate channel having opposed side walls, the method comprising:
-
- orienting the batten such that it is below the cross rail and substantially perpendicular thereto;
- urging the side walls of the batten toward one another such that a width of the urged batten is less than that between adjacent latching members;
- inserting at least an upper end of the side walls of the batten between adjacent latching members of two adjacent pairs of opposed latching members; and
- releasing said urging such that the side walls move away from one another and the batten is held in position between adjacent latching members.
- An embodiment of the invention will now be described, by way of example only, with reference to the accompanying drawings in which:

FIG. 1B is a front view of the cross rail ofFIG. 1A ; -

FIG. 6 is a top perspective view showing the cross railFIG. 1A interconnecting a ceiling suspension rod and a batten; -
FIG. 7 is a side perspective view of a ceiling suspension clip configured to engage a cross beam according to embodiments of the present invention; -
FIG. 8 is a bottom perspective view of the clip ofFIG. 7 ; and -
FIG. 9 is a side view of the clip ofFIG. 7 . -
FIGS. 1A and 1B show across rail 6 according to embodiments of the present invention. Thecross rail 6 is in the form of an elongate channel, having anupper wall 30 and a pair of opposedlateral walls 44 extending downwardly therefrom. As will be discussed, theupper wall 30 is configured for engagement with one or more ceiling suspension clips 2 such that thecross rail 6 can be supported thereby. Thecross rail 6 also comprises pairs of opposed latchingmembers 46 via which one ormore battens 48 are securable to thecross rail 6. In the depicted embodiment, each latchingmember 46 of an opposed pair extends downwardly from a respectivelateral wall 44. -
FIGS. 2 to 4 show example battens 48 secured to thepresent cross rail 6. The depicted batten is anelongate furring channel 48 having a generally U-shaped cross section. The upper end of eachside wall 50 of the furring channel comprises an outwardly projectingflange 52 extending along the length of thefurring channel 48. Anouter end 54 of eachflange 52 curves downwardly such that the flange generally has a C-shaped cross section, the C facing downwards. - The
present cross rail 6 is configured to releasably and adjustably secure the depictedfurring channel 48 thereto. Referring toFIG. 4 , thecross rail 6 is held in place between twoadjacent latching members 46 a of onelateral wall 44 a, and the corresponding and opposedadjacent latching members 46 b of the otherlateral wall 44 b. As such, thebatten 48 is securable substantially perpendicularly to thecross rail 6 between two adjacent pairs of opposed latchingmembers - Referring to
FIGS. 1A and 3 , each latching member is in the form of a downwardly projectingtab 46. At least one side of eachtab 46 extends laterally outwardly (in the direction of the elongate cross rail) and carries an upwardly projecting hook-like tooth 56. Eachtooth 56 is configured to be received in the C-shapedflange portion 54 extending outwardly from theside walls 50 of thefurring channel 48, thereby latching to and under arespective flange 52. In other words, to secure afurring channel 48 to thecross beam 6, thefurring channel 48 is inserted into aspace 58 between adjacent latchingmembers 46, whereinopposed teeth 56 of theadjacent latching members 46 locate and latch against respectiveelongate flanges 52 of thefurring channel 48. - In certain embodiments, the width of the spacing 58 between adjacent latching
members 46 may correspond to that of thefurring channel 48 such that thechannel 48 can be slotted along the longitudinal axis thereof between the latchingmembers 46 without resistance therefrom. However, in such embodiments, thechannels 48 may be vulnerable to inadvertent movement in the longitudinal direction thereof. As such, in other embodiments, a width of thespace 58 between adjacent latchingmembers 46 is narrower than that of thefurring channels 48. In these embodiments, theside walls 50 of thefurring channel 48 are first resiliently urged (e.g., squeezed) toward one another to reduce the width therebetween, thereby allowing thefurring channel 48 to be moved vertically upwardly toward the cross rail 6 (rather than fed longitudinally) and inserted between adjacent latchingmembers 46. Once inserted, the urging can be removed, thereby allowing theside walls 50 of thefurring channel 48 to expand away from one another toward their original positions. However, during the expansion, theside walls 50 are obstructed by and thus abut and urge against respective adjacent latchingmembers 46 of thecross rail 6, which urging helps to fix the position of thefurring channel 48 relative to thecross rail 6. Advantageously, if a position of thefurring channel 48 relative to thecross rail 6 is to be adjusted, one can simply urge theside walls 50 of thefurring channel 48 together once again, thereby allowing for adjustment of thefurring channel 48 along the longitudinal direction thereof relative to thecross rail 6. - The
upper wall 30 of thecross rail 6 is configured to receive asuspension clip 2 so that thecross rail 6 can be hung therefrom.FIGS. 6 to 9 show an exampleceiling suspension clip 2 configured to interconnect asuspension rod 4 and thecross rail 6. In use, anupper clipping portion 8 of theclip 2 is adjustably engaged with a downwardly extendingsuspension rod 4 of the ceiling system, and alower portion 10 of theclip 2 is configured to engage with thecross rail 6 so that therail 6 can hang from theclip 2. Thelower portion 10 of theclip 2 is generally planar and comprises anengagement end 11 for securing to thecross rail 6. - The
engagement end 11 is configured to be inserted through a correspondingly shapedaperture 22 of thecross rail 6 for engagement therewith. Theengagement end 11 comprises acentral portion 24 that extends downwardly from the centre of the planarlower portion 10 of theclip 2. Thecentral portion 24 has a curvature along its length which extends out of the plane of the lowerplanar portion 10; this profile can provide theengagement end 11 with additional rigidity and strength so that it does not inadvertently detach from the lowerplanar portion 10 when loaded. - Extending laterally outwardly from the curved
central portion 24 are a pair oftabs 26. Thetabs 26 are in the same plane as that of the lowerplanar portion 10 but are vertically spaced from a bottom edge thereof. In this way, each tab defines an upper surface or edge 28 from which thecross rail 6 is configured to abut against and hang. To this end, the upper wall of thecross rail 6 comprises a series of spaced-apart apertures 22 configured to receive theengagement end 11 of theclip 2. Theapertures 22 are shaped and sized to receive the generallyplanar engagement end 11 of the depictedclip 2. In particular, theapertures 22 comprise a centralcircular opening 32, sized to rotatably receive the curvedcentral portion 24 of theengagement end 11. Extending outwardly from thecircular opening 32 are a pair ofslits 34, each sized to receive a respectiveplanar tab 26 of theengagement end 11. - To engage the
clip 2 with thecross rail 6, theclip 2 is moved into a first orientation wherein thelateral tabs 26 thereof are aligned with and can thus be inserted through the correspondingslits 34 of thecross rail 6. Once inserted, and with reference toFIG. 6 , theclip 2 is rotated about the longitudinal direction thereof into a second orientation wherein thetabs 26 are no longer aligned with theslits 34, and thus theengagement end 11 cannot be withdrawn from thecross rail 6. In the depicted example, theclip 2 is rotated approximately 90 degrees in the longitudinal direction thereof such that the plane of thetabs 26 is generally perpendicular to that of theslits 34 in thecross rail 6. This rotation of the insertedclip 2 is achieved via rotation of the curvedcentral portion 24 thereof within thecircular opening 32 of theaperture 22 in thecross rail 6. The space orclearance 36 between the tabs 18 and the planarlower portion 10 is sized to admit or receive theupper face 30 of thecross rail 6 adjacent to theapertures 22 thereof. - When the
clip 2 is moved into the second orientation, as shown inFIG. 6 , theupper edge 28 of eachtab 26 abuts against an interior surface of theupper wall 30 of thecross rail 6. Moreover, the weight of thecross rail 6, and any additional ceiling components that are attached thereto, cause thecross rail 6 to bear downwardly against and hang from theupper edges 28 of the tabs 18, thereby impeding against relative rotation between thecross rail 6 and theclip 2. In this way, theclip 2 cannot inadvertently escape or be withdrawn from thecross rail 6. Of course, if such withdrawal were desired, a user can raise thecross rail 6 slightly relatively to theclip 2 so that thecross rail 6 no longer bears downwardly upon thetabs 26, and then rotate theclip 2 back into the first orientation such that theengagement end 11 is aligned with theaperture 22 of the cross rail to permit withdrawal therefrom. - Referring to
FIGS. 1 and 2 , the outer end of theupper edge 28 of eachtab 26 is provided with an upwardly extending tooth orprojection 38. Meanwhile, on opposite sides of eachaperture 22 of thecross rail 6 are a pair ofopenings 40. When theengagement end 11 of theclip 2 is inserted into thecross rail 6 and rotated into position (as perFIG. 6 ), theprojection 38 of eachtab 26 is configured to be located in a respective one of theopenings 40 in thecross rail 6; this location helps to further resist inadvertent relative rotation between thecross rail 6 and theclip 2 from which it hangs. - Many modifications of the above embodiments will be apparent to those skilled in the art without departing from the scope of the present invention. For example, with reference to
FIG. 1A , it will be appreciated that the end latching members of the cross rail may simply have one tooth, whereas the inner or central tabs comprise two. The latching members may of course have other shapes and configurations, provided that they work to hold therebetween a batten. Preferably, thecross rail 6 is integrally formed from a material such as galvanised steel, though of course other constructions and materials are considered within the scope of the present specification. - The
present cross rails 6 may also be used to form the frame of a wall. For example, with reference toFIG. 5 ,certain cross rails 6 are shown clipped to a wall and extending vertically upwardly so as to function as a wall stud. The versatility of the cross rail in its ability to be used not only as ceiling components, but also wall components, provides opportunities for reducing the amount of material waste on-site, particularly when used in respect of multistory buildings. E.g., rather than having unused prior art cross rails or wasted offcuts thereof which need to be transported back down the multistory building for disposal, there are opportunities forcross rails 6 embodying the present invention to be utilised in other applications, such as in wall framing and the like. - Throughout this specification and the claims which follow, unless the context requires otherwise, the word “comprise”, and variations such as “comprises” and “comprising”, will be understood to imply the inclusion of a stated integer or step or group of integers or steps but not the exclusion of any other integer or step or group of integers or steps.
- The reference in this specification to any prior publication (or information derived from it), or to any matter which is known, is not, and should not be taken as an acknowledgment or admission or any form of suggestion that that prior publication (or information derived from it) or known matter forms part of the common general knowledge in the field of endeavour to which this specification relates.
Claims (12)
1. A cross rail to which one or more battens of a suspended ceiling system can be secured, the cross rail comprising:
an elongate channel having an upper wall via which one or more ceiling suspension clips are engageable to support the cross rail;
opposed lateral walls extending downwardly from the upper wall; and
pairs of opposed latching members via which one or more battens are securable to the cross rail, each latching member of a pair extending downwardly from a respective lateral wall such that, in use, a batten is securable substantially perpendicularly to the cross rail between two adjacent pairs of opposed latching members.
2. The cross rail of claim 1 , wherein the latching members project downwardly from the lateral walls.
3. The cross rail of claim 2 , wherein adjacent latching members are spaced apart from one another along a length of the lateral walls, which spacing is shaped and sized to receive at least an upper end of the batten.
4. The cross rail of claim 1 , wherein each latching member comprises one or more teeth configured for latching to a corresponding flange of the batten.
5. The cross rail of claim 1 , wherein the upper wall comprises apertures for reception of a respective ceiling suspension clip such that the cross rail can be hung therefrom.
6. The cross rail of claim 5 , wherein each aperture comprises a slit configured to receive an engagement end of the suspension clip.
7. The cross rail of claim 5 , wherein each aperture further comprises a central opening extending through the slit to permit rotation of the suspension clip about a longitudinal direction thereof relative to the cross rail.
8. The cross rail of claim 5 , wherein the upper wall further comprises one or more openings associated with a respective aperture, each opening being configured to locate a corresponding projection of the suspension clip when inserted so as to retain an orientation of the cross rail relative to the suspension clip(s) from which it depends.
9. The cross rail of claim 1 , wherein the cross rail is integrally formed.
10. The cross rail of claim 1 , wherein the cross rail is made from galvanised steel.
11. A suspended ceiling system comprising:
suspension rods;
ceiling suspension clips secured to respective suspension rods;
cross rails, the cross rails hanging from the suspension clips and being spaced apart in a transverse direction; and
battens spanning across and being secured to two or more adjacent and spaced apart cross rails, wherein each of the cross rails comprise:
an elongate channel having an upper wall via which one or more ceiling suspension clips are engageable to support the cross rail;
opposed lateral walls extending downwardly from the upper wall; and
pairs of opposed latching members via which one or more battens are securable to the cross rail, each latching member of a pair extending downwardly from a respective lateral wall such that, in use, a batten is securable substantially perpendicularly to the cross rail between two adjacent pairs of opposed latching members.
12. A method of securing a batten to a cross rail the batten comprising an elongate channel having opposed side walls, the method comprising:
orienting the batten such that it is below the cross rail and substantially perpendicular thereto;
urging the side walls of the batten toward one another such that a width of the urged batten is less than that between adjacent latching members;
inserting at least an upper end of the side walls of the batten between adjacent latching members of two adjacent pairs of opposed latching members; and
releasing said urging such that the side walls move away from one another and the batten is held in position between adjacent latching members.
