Description

[0001] A Support Member for a Suspended Ceiling

[0002] Field of Invention

[0003] The present invention is in the field of support members for a suspended ceiling. More specifically, the present invention is in the field of support members for suspended ceilings that are to be used in data centres.

[0004] Background

[0005] A suspended ceiling is a secondary ceiling feature often attached to the main structural ceiling of a building. Data centres benefit from suspended ceilings for many reasons. One such reason is that suspended ceilings provide a plenum above a room that can be used for expelling hot air. This in turn allows cooler air to enter the room to replace the hot air. Such airflow management systems provide efficient cooling means to service rooms with large amounts of heat generating sources, such as computers or other pieces of machinery. The above described is a simple airflow management system comprising only a single air channelling means. However, these systems can be further developed into a more comprehensive aisle containment systems that comprise additional plenums for transferring hot and cool air by introducing vertical (and horizontal) panels implemented to channel such air in a more constrained manner.

[0006] Furthermore, suspended ceilings are also able to suspend items that are usually necessary in data centres in a more stable manner than by suspension through the main structural ceiling of a building. This is because the use of a suspended ceiling enables the use of a shorter suspending means (since suspended ceilings are closer to ground level). Said items may be pieces of machinery, aisle containment system panels, conduits for cooling or cable management baskets for connectivity.

[0007] Suspended ceilings are integral pieces of infrastructure for data centres however current suspended ceilings are prone to instability issues and weak structural points in their support members. These issues can severely hamper their function and pose a security risk for people standing underneath the suspended items or increase the risk of damaging the suspended items themselves. The main issue relates to the deformation of support members at attachment points (either the attachment to the ceiling or to items suspended from the suspended ceiling).

[0008] The present invention addresses at least this issue and more.

[0191] Figure 1 shows a support member 10 for a suspended ceiling (not shown), wherein the support member 10 comprises an elongate body extending in a longitudinal direction, wherein the support member 10 comprises a cross section in a plane orthogonal to the longitudinal direction, the cross section comprising; a first internal shelf 11; a first side wall 13; a second side wall 15; a first channel 17; a second channel 19; a first pair of ledge members 21; wherein the first internal shelf 11 is configured to extend between the first side wall 13 and the second side wall 15 and define a boundary between the first 17 and second channels 19; wherein the first channel 17 is adjacent a proximal end (annotated P in Figure 1) of the cross section of the support member 10, and wherein the second channel is adjacent a distal end (annotated D in Figure 1) of the cross section of the support member 10; wherein the first channel 17 and the second channel 19 are configured to extend in the longitudinal direction; wherein the first channel 17 comprises a first opening 23, and wherein the second channel 19 comprises a second opening 25; wherein the first opening 23 and the second opening 25 are configured to extend in the longitudinal direction; wherein the first opening 23 is adjacent the proximal end, and wherein the second opening is adjacent the distal end; wherein the first channel 17 and / or the second channel 19 comprises the first pair of ledge members.

[0192] A suspended ceiling relates to a second ceiling feature that is positioned below and suspended from the main structural ceiling of a building (not shown). The support members 10 described above and herein are the main structural and load carrying components of said suspended ceilings. In this sense, the support members 10 are also positioned below and suspended from the main structural ceiling of the building. The proximal end P as referred to above relates to a top end (or top side) of the support member in its use orientation. Here, "use" is described in the context of when a support member 10 is part of a suspended ceiling or part of a grid system for such suspended ceilings. As such, this proximal end P is the top end that is closest to the main structural ceiling of the building in use. In line with this, the distal end D as described above relates to a bottom end (or side) of the support member in use (with "use" following the same definition as above). This is the end of the support member 10 that is closest to the ground in use. Although not seen in the embodiment of the support member 10 of Figure 1 (by virtue of the support member 10 comprising external flanges at its distal end), other embodiments (those without these external flanges) and those that comprise symmetry in a horizontally extending central axis, or a high level of such symmetry, may have proximal and distal ends that areinterchangeable in use. This means that the support member 10 may be oriented either way up as part of a suspended ceiling. This may make assembly of such suspended ceilings more efficient and convenient for an assembler.

[0193] Figure 1 shows a cross section of a first embodiment of the support member 10. The base profile of said cross section comprises parallel, or substantially parallel first 13 and second side walls 15, that are separated by a first internal shelf 11. In this embodiment, the first internal shelf 11 is situated approximately at the centre of the height of the support member 10. In other embodiments, it may be situated closer to either the proximal P or distal ends D. This base profile is particularly efficient at carrying vertical, horizontal, compressive and tensile loads without the high weight cost. Therefore, with such a base profile, a weight efficient and structurally robust support member 10, that is not prone to deformation, can be used alongside other support members 10 of the same to form grid systems to make reliable and secure suspended ceilings.

[0194] This base profile naturally enables channels to be formed within the internal portion of the cross section. A first channel 17 is located at the top (proximal to the proximal end of the support member) and the second channel 19 is located at the bottom (proximal to the distal end of the support member). These first 17 and second channels 19 enable openings 23, 25 from both the proximal end and the distal end to the centre of the support member's cross section. These first 23 and second openings 25 enables an attachment element (not shown) to have access to an internal portion of the support member 10. Such access enables the attachment element to more completely clamp, or grip, a portion (flange) of the support member 10 when used in conjunction with a lock nut placed on a second side of the flanges. This in turn leads to a more secure attachment than if the attachment element was to merely attach by virtue of external abutment with the support member 10. This complete grip also distributes loads more evenly and prevents localised deformation of the support member 10 at the attachment location.

[0195] An attachment element (not shown) as herein described relates to a channel nut. Said channel nut may comprise a cuboidal shape with one dimension of its planform longer than the other or it may comprise a more uniform square planform. A lock nut is used in conjunction with the channel nut and is placed on an external side of the support members. Said lock nut and channel nut may compress / clamp flanges of the support member to provide a comprehensive attachment. This mechanism is described in greater detail later.In this embodiment of Figure 1, the support member 10 comprises both a first 21 and a second pair 27 of ledge members that reside within the first channel 17 and the second channel 19 respectively. Each ledge member of the first 21 and second pair 27 of ledge members extend from an inner (lateral) surface of the first 13 and second side walls 15 respectively and towards the centre of the support member 10. In doing so each ledge member provides a thick geometry region within these channels at locations from where they extend from the side walls. This additional local thickness further reinforces the geometry of the support member 10 in regions that may otherwise be prone to deformation, for example, regions at the centre point of the first 13 and second side walls 15 which comprise long unsupported stretches of geometry.

[0196] In the embodiment seen in Figure 1, a free end of the first and second ledge members of both pairs of ledge members (first 21 and second 27), are separated by 35mm. This range of separation in other embodiments may be between 30-40mm. The extension of the first ledge member towards the centre of the support member is the same as the second ledge member for both the first 21 and second pairs 27 of ledge members. In other embodiments this may not be the case. Such embodiments may comprise the first and second ledge members of each pair of ledge members extending different amounts to one another. This may result in an offset separation with respect to the centre of the cross section of the support member 10. Such embodiments may therefore be asymmetric down a vertical axis extending through a centre line of the cross section of the support member 10.

[0197] Furthermore, the embodiment seen in Figure 1 shows that the extension of the first and second ledge members towards the centre of the support member 10 of both the first 21 and second pairs 27 of ledge members is the same. Hence, the separation of the free ends of each pair of ledge members are the same. Other embodiments may comprise of a different separation between the free ends of the first and second ledge members of the first pair of ledge members 21 when compared to the second pair of ledge members 27. Said support members 10 may comprise symmetry in a vertical axis extending through the centre of the support member 10 but not in a horizonal axis (disregarding any flange features to be described herein).

[0198] Figure 1 shows first and second ledge members of both the first 21 and second pairs of ledge members 27 comprising a thickness of 3mm. In other embodiments this thickness may be between 2 and 5mm. Figure 1 also shows the first and second ledge members of each pair of the first and second ledge members 21, 27 being arranged at the same height as their counterpart. However, it is possible that in otherembodiments each ledge member of the pair may be arranged at differing heights. This may aid in compressing attachment elements of differing thicknesses and hence being able to accommodate attachment elements of differing thicknesses.

[0199] Also seen in Figure 1 are a pair of first flanges 29 that are situated at a proximal end of the support member. These first flanges 29 extend inwardly across the opening 23 of the first channel 17. These first flanges 29 provide a surface for mechanically engaging with an attachment element (not seen in Figure 1). This mechanical engagement is described in more detail later. Said attachment elements on this proximal side of the support member 10 attach the support member with a suspending element (not shown), wherein the suspending element is attached to the main structural ceiling of a building. The first flanges 29 also extend along the elongated profile of the support member 10 and this enables multiple attachment elements to be implemented along the length of the support member 10 should they be needed. Similarly, the support member 10 of Figure 1 comprises a pair of second flanges 31 situated at a distal end of the support member 10. In line with the pair of first flanges 29, these second flanges 31 also extend inwardly and partially across the opening 25 of the second channel 19 and provide a surface for mechanically engaging with a second attachment element (not shown). These second attachment elements on this distal side of the support member attach the support member 10 to an item (not shown) suspended from the suspended ceiling or support member 10. Alternatively, attachment on this distal end of the support member may be with panels for air plenums or aisle containment systems (not shown).

[0200] This distal end of the support member 10 also comprises a pair of external flanges 33. The free ends of each individual flange of these external flanges 33 extend laterally from the support member 10 in opposing direction to one another. These external flanges 33 are configured to provide a flat surface onto which a portion of a perimeter of a ceiling tile (not shown) is to be seated. In a suspended ceiling formed of a grid of the described members, these external flanges 33 form a platform (comprising of flat surfaces) onto which a ceiling tile or group of ceiling tiles can sit. The external flanges may extend between 5-15mm beyond the external sides of the first and second walls. In the particular embodiment seen in Figure 1, the external flanges extend beyond this reference point by 10mm.

[0201] Not seen in the cross section view of Figure 1 is the extension of the support member 10 in the longitudinal direction. This is instead best seen in the perspective view of the suspended ceiling of Figure 5. The support members used to form such suspended ceiling comprise cross sections consistent with that seen in Figure 1 along the entirelength of the support member. In alternative embodiments, the cross section of the support member may only take this exact described form at proximal locations to attachment points, whereas in between said attachment points, the support member may comprise a cross section of a more regular shaped beam.

[0202] Figure 2 shows an exemplary attachment arrangement between a suspending element as described (and attached to the main structural ceiling of a building) with the first flanges 29 of the support member 10 when utilising an attachment element 35 as described. Figure 2 shows the attachment element 35 residing within the first channel 17 and in a position where it abuts a first surface of the first flange 29. Here, first surface refers to an internal face (i.e. one facing the centre of the support member 10) of the first flange. In its simplest form therefore, the mechanical engagement between the first flange and the attachment element simply comprises of the first faces of the first flanges 29 being utilised to contact the attachment element.

[0203] This attachment arrangement also comprises the attachment element 35 being mechanically constrained to a portion of the suspending element, i.e. via a threaded connection 37 or other. Here, the weight of the support member 10 is therefore partially supported by the attachment element 35 which in turn is supported by the constrained suspending element.

[0204] Another aspect of this attachment is a lock nut 36 placed on an external side of the first flanges 29. The lock nut 36 is configured to provide a force onto a second face (or second faces) of the first flanges such that the first flanges are compressed between the lock nut and the channel nut (the attachment element 35). Said compression of the first flanges 29 provides a particularly firm attachment without the need of complicated geometry built into the support member 10 such as threaded profiles or the like.

[0205] Alternative embodiments to that seen in Figure 2 may comprise additional, optional aspects to said attachments. Such alternative embodiments may further utilise the first pair of ledge members to provide addition mechanical support to the attachment element 35 by constraining the attachment element 35 between the first faces (or at least one face) of the first flanges 29 via a compression of the attachment element 35. For such attachment mechanism, the attachment elements need be sized to fit within this space.

[0206] In the embodiment of Figures 1 and 2 the distance between the first face of the first flange and the upwards facing face of the ledge member (of the first pair) is 3.5mm. In other embodiments this may be in the range of 3 to 4mm. Attachment elements35 will need to have a thickness that matches these dimensions to an acceptable tolerance for a snug fit in such attachment arrangements.

[0207] Although not seen in Figure 2, the attachment mechanism between the second flanges 31 at the distal end of the support member 10 and a second attachment means (not shown but of similar construction to the attachment means 35 of Figure 2) is much the same as the first flanges described above. However, in this scenario it is the weight of the item that is being suspended that is being supported by the support member as opposed to the reverse arrangement with the suspending element 10. Furthermore, in line with that mentioned in the description of Figure 1, the first flanges 29, second flanges 31 and external flanges 33 too extend in the longitudinal direction in the embodiments seen thus far. In other embodiments, they may only extend in this direction, or be present, in areas proximal to attachment portions. In other portions of the elongate body that aren't proximal to the attachment regions these flanges 29, 31, 33 may be absent.

[0208] Figure 3 shows a second embodiment 40 of the support member described in Figures 1 and 2. This second embodiment 40 is largely similar to the first embodiment 10 in terms of its base profile. However, one key difference is that this second embodiment 40 comprises a second internal shelf 41a. This second internal shelf 41a is situated between the second pair of ledge members 27a in the second channel 19a and the first internal shelf 11a. This second internal shelf 41a partitions the second channel 19a as described in Figures 1 and 2 into a third channel 43a that extends between the first internal shelf 11a and the second internal shelf 41a and wherein the second channel 19a in this reference system now extends from the second internal shelf 41a to the second opening 25a at the distal end of the support member 40.

[0209] In the embodiment seen in Figure 3, this second internal shelf 41a is split into a first shelf portion and a second shelf portion by virtue of comprising a central opening 45a. This may alternatively be described as a separation of the free ends of the first and second shelf portions. The first and second shelf portions each extend from the first and second side walls 13a, 15a respectively in the same manner described above for the first and second pairs of ledge members 21a, 27a. There may also be embodiments where the second internal shelf 41a is not split and instead is a complete shelf that extends between the first and second side walls 13a, 15a in line with the first internal shelf 11a described above.

[0210] In the embodiment seen, the second internal shelf 41a, or the first and second shelf portions of the second internal shelf, is / are 4mm thick. In other embodiments, thesecond internal shelf 41a, or the first and second shelf portions of the second internal shelf 41a may be any thickness between 2 to 5mm.

[0211] In the embodiment seen, the free end of the first shelf portion is spaced from the free end of the second shelf portion by 22mm, in other embodiments they be spaced by any distance between 20-25mm. The free ends of the first and second internal shelf portions may extend further than the free ends of the first and second ledge members of either the first and second pair of ledge members 21a, 27a. Alternatively, there may be no free ends of the first and second shelf portions in which the second internal shelf is a complete shelf that extends without break between the first and second side walls 13a, 15a.

[0212] In line with the first and second channels 17a, 19a, the third channel 43a seen in Figure 3 also extends in the longitudinal direction of the elongate body. Due to the location of the third channel 43a being between the first internal shelf 11a and the second internal shelf 41a, the third channel 43a is substantially concentric with the support member's 40 cross section.

[0213] The separation between the first internal shelf 11a and the second internal shelf 41a in the embodiment seen is 23mm. However, this can be any value between 20-25mm in other embodiments. This distance defines the height of the third channel 43a. It is to be noted that this second embodiment of the support member 40 is taller in height than the first embodiment 10. This increase in height enables the accommodation of the second internal shelf 41a by creating additional vertical space for it and does so whilst maintaining appropriate tolerances of the cross section features described above and herein. It is also to be noted that the first internal shelf 11a now resides in a more proximal location with respect to the support member 40 (towards the proximal end of the support member) to create additional vertical space for the second internal shelf 41a.

[0214] The width of the support members of both embodiments 10, 40 are consistent with one another and are circa 50mm at a portion that does not comprise the external flanges 33, 33a or circa 70mm when considering the width from the free end of a first external flange 33, 33a to a free end of a second external flange 33,33a.

[0215] This third channel 43a is also substantially rectangular and dimensioned so as to accommodate a reinforcement bar (not shown) of a complementary cross section or an undersized cross sectional area with respect to the third channel 43a. The reinforcement bar (not shown) is to be used to stiffen the support member 40 along its extended length. This may be useful when the support member 40 is to suspendheavier items from itself. This reinforcement bar may reduce the amount of deformation as a result of such suspension. The described reinforcement bars may only be implemented in portions along the elongate body at which the items are suspended or at specific load prone stretches along the elongate body thereof. The third channel 43a may also be useful in accommodating any other long slender item such as a conduit of acceptable size (not shown).

[0216] Both the external lateral sides of the first and second side walls 13, 13a, 15, 15a of both embodiments described thus far comprise straight and level sides. This yields a uniform external profile that can form compact structures and / or enable flush abutment with the perimeter of a tile.

[0217] Figure 4 shows the attachment between the second embodiment of the support member 40 seen in Figure 3 with a suspending element via an attachment element 35. This mechanism is consistent with that as explained in Figure 2 and is not repeated once again for the sake of conciseness. Once again, this same attachment mechanism applies should any item (not shown) be suspended from the support member 40 at its distal end. It is noted in Figure 4 that the external flanges 33a extend laterally such that an item can accommodated to the side of the support member. In this case a ceiling tile 47a is accommodated here.

[0218] Figure 5 shows a portion of a suspended ceiling 50 formed from a grid of second embodiment support members 40 described in Figures 3 and 4. Similarly, it is entirely possible to construct a suspended ceiling of the same general form as that seen in Figure 5 utilising the first embodiment of the support member 10 described in Figure 1.

[0219] The suspended ceiling portion seen in Figure 5 comprises a grid of length defining support members and width defining support members. The length defining support members 40L are of a first length and are suspended parallel to each other. These are the support members that extend in a direction that is diagonal across the top left and the bottom right of the Figure. Six length defining support members are seen in the portion of Figure 5 and are herein described as lengthwise support members 40L. The suspended ceiling portion seen in Figure 5 also comprises width defining support members of a second, shorter length to the lengthwise support members. These width defining support members 40W are arranged orthogonally and in between the lengthwise support members. These are referred to herein as the width wise support members 40W.Additional embodiments of the suspended ceiling 50 may comprise another pattern of placing the support members 40 to that seen in Figure 5 and to form the suspended ceiling 50 or they may maintain this same pattern. For example, the suspended ceiling seen in Figure 5 comprises four (two on each side) lengthwise support members 40L defining the edge of the suspended ceiling 50 with a central pair of lengthwise members 40L arranged in. Shorter width wise support members 40W are arranged in between these lengthwise members defining a web. Other embodiments may comprise only one length of support members 40 throughout.

[0220] Figure 5 only shows a portion of a suspended ceiling 50. It is entirely possible that the suspended celling comprises more support members 40 than those shown and extend in any of the lengthwise or width wise directions shown in Figure 5.

[0221] Figure 5 also shows supporting ribs 51 that extend in the width wise direction for additional stability for the suspended ceiling. Other embodiments may not comprise these supporting ribs 51.

[0222] The suspended ceiling 50 of Figure 5 also comprises tiles that sit atop the square platform. Here, the square platform refers to that formed between adjacent width wise 40W and lengthwise support members 40L.

[0223] Seen best in the exploded infographic of Figure 6, the suspended ceiling 60 also comprises attachment elements 35 within the first channel 17a of each support member 40, wherein these attachment elements 35 are used to attach or mechanically constrain the support members to the main structural ceiling of a building via suspending elements 61 (metallic rods in Figure 5 but may be cables in other embodiments). Such attachment may be directly with the suspending element (i.e. the suspending element 61 attaching to the support member with an attachment element 35 and sharing a common axis) or via an attachment plate 63 that is used to attach together adjacent support members 40 (at or proximal to the intersection points of said support members).

[0224] The suspending elements in Figure 5 comprise rectangular shaped connectors 53 whereas the suspending elements in Figure 6 comprise C-shaped connectors 65. Either of these two embodiments may be compatible within suspended ceilings 50, 60. A benefit of the rectangular shaped connectors 53 may be uniform loading when suspending the support members 40 (or suspended ceiling altogether) from the suspending elements 61.

[0225] Depending on the intersection points, these attachment plates 63 may be T shaped or L shaped or shaped like an addition sign "+" (referred to as cross shape). Figure 7best shows these various types of attachment plates along with their use configuration in the suspended ceiling of Figure 5. A T shaped attachment plate 63b can attach together with up to three support members (two co-linear and one orthogonal) and is best implemented on the central edge portions of a suspended ceiling. An L shaped attachment plate 63c can attach together with up to two orthogonal support members and is best implemented at a corner of a suspended ceiling. A cross shaped attachment plate 63a may attach with up to four orthogonal support members together and best implemented in the centre portion of the suspended ceiling.

[0226] The attachment plates themselves in the embodiment seen in Figure 5 are configured to be placed atop the support members 40 and overlapping the support members 40 that they are to constrain together.

[0227] Although not seen in Figure 5, the suspended ceiling may further comprise a suspended item (not shown) that is suspended from one or more of the support members 40. Such suspended items may be attached to the support members 40 at points near coaxial with the suspending elements or proximal to the support members intersections. Suspending items from these locations may reduce loads that may otherwise be applied to the long straight stretches of the support members. This may lead to deformation more readily. These suspended items may be attached to the support member 40 through the attachment plates located on the distal ends of the support members (following the same convention as described above).

[0228] Such suspended items may be conduits used for ventilation, baskets for holding cables or other items needed in data centres. They may even be heavy machinery components. In some embodiments, the suspended items need not be suspended so as to have their weight supported by the support members and may instead relate to items merely attached to the support members on their distal ends and otherwise contacting or attached to the floor. Such items may be aisle containment system panels used to form compact pods of data centre rooms.

[0229] Figure 8 shows a support member clip 80 of a first embodiment. This support member clip 80 may be used to stiffen portions of the support member 40 in use, or as a means of attaching elements to the support member. The cross section of the support member clip 80 (best seen in Figure 8a) comprises geometry suited to partially clamping the support member 40 described above. Particularly, when considering the cross section of the support member clip 80, the support member clip 80 comprises a top (proximal) side 81 that is substantially horizontal and configured to abut the top side (proximal end of the support member). The cross section further comprises first and second clip side walls 83, 85 that extend vertically in the first direction(downwards in use or the direction as defined from the proximal end to the distal end of the support member or support member clip thereof) or substantially in such direction. These first and second side clip walls 83, 85 are configured to abut and lightly clamp the side walls 13a, 15a of the support member 40 on an exterior side. The distance between the first and second clip side walls 83, 85 tapers down from the proximal end to the distal end so as to aid such clamping.

[0230] The top side 81 of the support member clip and the first and second clip side walls 83, 85 form a shell that lightly clamps the support member 40 from the top or proximal side. The distal end of the support member clip or more particularly the distal end of the first and second clip side walls comprise lateral flanges 87. Said lateral flanges 87 may enable an easier grip for a user from which to expand the support member clip to fit atop the support member to remove it therefrom. The extension of the each of the lateral flanges in the embodiment seen is towards the second and third direction respectively, wherein the second and third direction are lateral directions towards the right and left of the figure respectively.

[0231] The support member clip 80 further comprises a first angled portion 89a and a second angled portion 89b that extend from a proximal end of the support member clip 80 (when viewed in its cross section). The distal ends of these first and second angled portions 89a, 89b are configured to contact and maintain a slight pressure on the first surfaces of the first flanges 29a of the support member 40 (arrangement best seen in Figure 8b). This mechanism preserves the shape of the first flanges 29a and provides additional protection to deformation since the first flanges 29a are largely unsupported over the length in which they extend across the first opening 23a of the first channel 17a. The first flanges 29a are also exposed to the external environment and thus prone to external forces or impulses.

[0232] The first and second angled portions 89a, 89b comprise a vertical element that extends in the first direction, wherein the first direction is once again downwards (or the direction between the proximal end and the distal end of the support member). The first and second angled portions each comprise a distal end that is upturned 91a, 91b (and therefore extends back towards the proximal end). These distal ends also extend in laterally opposite directions to one another, wherein the distal end of the first angled portion 89a extends in the second direction and wherein the distal end of the second angle portion 89b extends in the third direction. The second direction extends partially to the right in Figure 8 and the third direction extends partially to the left. Furthermore, the angle between the first direction and the second direction is the same as the angle between the first direction and the third direction. Theseangles in the embodiment seen in Figure 8 are 32 degrees but may be any angle between 30-35 degrees.

[0233] In terms of manufacturing these first and second angled portions 89a, 89b, it is of a preferred embodiment that the support member clip 80 be formed of a unitary piece of material to ensure flexibility and clamping performance. In line with this, the first and second angled portions 89a, 89b may be formed of the top side of the support member clip that has been partially cut (leaving the proximal ends of the angled portions integral with the top side 81) and bent in the first direction and angled therefrom. These manufacturing steps result in a void 93a, 93b adjacent to the angled portions when viewed from a top side of the support member clip. This is best seen in Figures 8c and 8d.

[0234] Furthermore, the support member clip 80 itself is also an elongate body. The support member clips 80 may comprise a substantially shorter elongate body as opposed to the support member 40. In this embodiment the support member clip is 70 mm long. In other embodiments, it may be longer or shorter than this value. The support member clip 80 may be placed along the elongate body of the support member 40 at regular locations or placed at specific locations predicted to be prone to deformation. Figure 9 is a flowchart outlining a method 100 of operating a support member clip. Method 100 commences with step 101 of first aligning the first and second angled portions of the support member clip with the opening of the first channel of the support member. Due to the central location of the first and second angled portion within the support member clip, this may naturally or more conveniently be achieved by simply placing (by expanding and releasing) the support member clip side walls onto the exterior of the side walls of the support member. Step 102 then involves moving the first and second angled portions into the first channel. Once again, this may be achieved simply by lowering the support member clip until the top side of the support member clip abuts the top side of the support member. This may be a more convenient visual / physical feedback event. Steps 103 relates to the distal ends of the first and second angled portions of the support member clip contacting the free ends of the first flanges upon their entry into the first channel and flexing inwards towards the centre of the support member (step 104) by virtue of this contact. The "give" in the angled portions aids such flexion. Step 105 relates to a re-flex of the first and second angled portions back to their original position (that of before step 104) and away from the centre of the support member upon the complete entry of the first and second angled portions into the first channel, wherein complete entry comprises the top side of the support member clip abutting the proximal end of the support member.Step 104 and 105 are passive processes that occur due to the predefined dimensions of the angled portions and the support member clip. Neither of these flexions require active movement of the flanges and result passively as a result of the relative geometry of the support member clip and the support member.

[0235] Upon complete entry of the first and second angled portions into the first channel, the method further comprises the step of the distal ends of the first and second angled portions contacting the first surface of the first flanges. This is a final position of the support member clip within the support member.

[0236] Figures 10 a-d show a second embodiment of a support member clip 80' to that seen in Figures 8a-d. Like the first embodiment, this second embodiment 80' too comprises of a clip body that extends in the longitudinal direction with a cross section that is orthogonal to this direction of extension. Also in line with the first embodiment of the support member clip 80, this second embodiment too takes the form of a shell comprising three distinct portions. This three portion shell arrangement aids in placing the support member clip 80' atop the support member 40 (best seen in Figure 10b). The cross section of the support member clip 80' seen in Figure 10a shows a first of these portions as a top side 81', wherein the top side 81' is a substantially horizontal surface located at the proximal end of the cross section of the support member clip 80'. The 'proximal' end refers to the top end of the support member clip 80' in its use orientation atop the support member and thus follows the convention set out above. Also seen are first and second clip side walls 83', 85' (constituting the remaining two portions of this shell) that extend in substantially the first direction from the top side 81'. Here, the first direction is the vertical direction and is consistent with that described above too. Figure 10b shows the top side abutting the proximal end of the support member 40 during use and all three portions (the top side 81', the first 83' and the second clip side walls 85') clamping the support member 40 from a proximal side. The tapering (decreasing) distance between the first and second side walls 83', 85' further assisting this clamping by providing a compressive force to a distal portion of the support member, in particularly to distal portion of the first and second side walls of the support member 40. This arrangement allows for the support member clip 80' to both mechanically support the support member 40 in the contacted regions and aid in constraining the support member clip 80' atop the support member without additional means. Additional means may otherwise include adhesives or mechanical fixings (these may however be used in alternative embodiments for additional attachment strength). The distance between the distal end of the first clip side wall 83' and the second clip side wall 85' in this embodiment is 48 mm. This coincides with (or is undersized to a small degree from) a support member 40 width of circa 50 mm(in a non-flange portion). This enables the desired compression due to the slightly flexible (or giving) nature of the support member clip 80'. This distance in other embodiments of the support member clip 80' may be between 43 and 53mm and be sized dependant on the support member width.

[0237] Like the first embodiment 80 described in Figures 8a-d, this second embodiment of the support member clip 80' may also be used to stiffen portions of the support member 40 in use, or as a means of attaching elements to the support member 40. In addition to the clamping arrangement described, the distal end of the support member clip 80' or more particularly the distal end of the first 83' and second clip side walls 85' comprise lateral flanges 87'. Said lateral flanges 87'may enable an easier grip for a user from which to expand the support member clip 80' to fit atop the support member 40 or remove it therefrom. The extension of each of the lateral flanges 87' in the embodiment seen is towards the second and third directions respectively, wherein the second and third directions are lateral directions towards the right and left of the figure respectively. The angle between the lateral flanges 87' and the first and second clip side walls is 88 degrees in the embodiment seen. In other embodiments this angle may be in the range between 83 and 93 degrees. This angle range may enable sufficient protrusion from the first and second clip side walls so as to enable convenient handling or gripping by a user.

[0238] The support member clip 80' of this embodiment comprises first and second protruding portions 89', 89b' that are configured to extend from an internal face of the support member clip 80' and towards the support member 40. This internal face of the support member clip 80' referring to surfaces that face the support member during use i.e. when the support member clip is placed atop the support member. These protruding portions 89a', 89b' are additional contacting points between the support member clip 80' and the support member 40 and are used to provide structural support for deformation in prone areas (such as portions of the support member adjacent a flange). They also aid in constraining the support member clip 80' atop the support member 40' in the vertical plane. This functionality was provided by the first and second angled portions 89a, 89b in the embodiment describe in Figures 8a-d, and as such the first and second angled portions 89a, 89b can constitute first and second protruding portions 89a', 89b' in some embodiments. In Figures lOa-d, however, these first and second protruding portions 89a' 89b' extend from the first and second clip side walls 83', 85' (as opposed to the top side or proximal end) and towards the proximal end of the support member. The proximal ends of the first and second protruding portions being integral or extending from the first and second sideclip walls 83', 85'. Figure 10b shows these first and second protruding portions 89a', 89b' as extending towards and having their distal (or free) ends residing underneath an external flange of the support member, wherein the external flange is one defined by the external extension of the first flanges. In some embodiments, the distal ends of the these protruding portions 89a', 89b' may additionally contact an underside of these external flanges along with the side walls of the support member. In Figure 10a, the angle between the direction in which the first and second protruding portions 89a', 89b' extend and the direction in which each of the first and second clip side walls 83', 85' extend is 20 degrees (respectively) when taken from the proximal side of the support member clip (or 160 degrees when taken from the distal side). In other embodiments, this angle may be in the range of 15-25 degrees from a proximal side (or 155-165 degrees from the distal side).

[0239] Once more, in terms of manufacturing these first and second protruding portions 89a', 89b', it is of a preferred embodiment that the support member clip 80' be formed of a unitary piece of material to ensure flexibility and clamping performance. In line with this, the first and second protruding portions 89a', 89b' may be formed from a portion of the top side 81' and a portion of the first 83' and second clip side walls 85' (respectively) that have been partially cut and bent so as to achieve the abovementioned angular extension. These manufacturing steps result in a pair of voids 93a', 93b' being formed adjacent each of the first and second protruding portions and from the removal of the first and second protruding portions 89a', 89b' from the support member clip 80'. A first void extending 93a' across a portion of the top side 81' and the first clip side wall 83' and a second void 93b' extending across a portion of the top side 81' and the second clip side wall 93b'.

[0240] As mentioned, the support member clip 80' of this second embodiment is also an elongate body. The support member clips 80' may comprise substantially shorter elongate bodies when compared to the support members themselves. In this embodiment the support member clip 80' is 70 mm long. In other embodiments, it may be longer or shorter than this value. The support member clips 80' may be placed along the elongate body of the support member 40 at regular locations or placed at specific locations predicted to be prone to deformation.

[0241] Figure 11 shows a flowchart outlining a methodology 110 of positioning a support member clip onto a support member for a suspended ceiling. The support member and the support member clip referred to herein this methodology may be those as described above. Other support members or support member clips comprising of a number but not all of features for these elements as described above may also utilisethe same method steps described below for attachment. Method step 111 relates to expanding the first and second clip side walls so as to increase the (lateral) distance between the first and second clip side walls. This achieves the desired clearance to place the support member clip upon the support member by ensuring the width between the first and second clip side walls is greater than the width of the support member. This step may further utilise contact between the distal ends of the support member clip side walls and the support member side walls. This may be after an initial user forced expansion and wherein this contact may further ensures the required (expanded) distance is maintained across the entire lengths of the first and second clip side walls. This method step may be implemented by a user simply holding and manually separating the first and second clip side walls or it may include the utilisation of a chamfered corner (or other curved geometry), such as that between the support member clip side walls and the lateral flanges, to guide the support member clip into expansion when a downwards / translating force is applied. Method step 112 relates to positioning the support member clip onto the support member, such that the top side of the support member clip abuts the proximal end of the cross section of the support member. This is the use case configuration and clamping position of the support member clip atop the support member. Method step 113 relates to abutting the first and second side walls of the supporting member with a portion of the first and second clip side walls, when the top side of the support member clip abuts the proximal end of the cross section of the support member. This step achieves the required flush, clamping positioning of the support member clip atop the support member and the associated compression provided by the support member clip. This final abutment may further comprise the abutment of the support member with the first and second protruding portions of the support member clip. This abutment may take place between the distal (free) ends of the protruding portions and a portion of each of the side walls of the support member. This may be a portion of the side walls that reside directly underneath external flanges (the external extension of the first flanges) or an underside portion of these external flanges themselves.

[0242] Prior to this final abutment and after the initial expansion of the first and second clip side walls, the support member clip may be translated downwards (in the first direction). During said translation the method steps may further include the flexing of the first and second protruding portions away from a centre axis of the support member clip (or their initial unflexed position) upon contact with the proximal end of the support member, for example, the externally extending portion of its first flanges. Once the distal ends of these protruding portions are clear of this initial contacted region (during the translation), the method steps may further include flexing the firstand second protruding portions back towards the centre axis of the support member clip, i.e. from their flexed position to their unflexed or less flexed positions.

[0243] The above embodiments are to be understood as illustrative examples. Further embodiments are also envisaged. It is to be understood that any feature described in relation to any one embodiment may be used alone, or in combination with other features described and may also be used in combination with one or more features of any other of the embodiments, or any combination of any other of the embodiments. Furthermore, equivalents and modifications not described above may also be employed without departing from the scope of the invention, which is defined in the accompanying claims.
