Description
A PLANAR SUSPENDED CEILING SYSTEM AND A METHOD FORINSTALLING THE CEILING SYSTEM Field of the invention The present invention relates to a planar suspended ceiling system and amethod for installing such a suspended ceiling system. The invention morespecifically relates to such a suspended ceiling system comprising foldableceiling tiles.
Background artSuspended ceilings are well known and may serve a variety of purposes. One purpose may be to provide sound absorption or other insulation in andoutside of a room. Typically, a suspended ceiling system comprises a grid ofprofiles supporting a plurality of ceiling tiles arranged in frames formed by thegrid of profiles.
Ceiling tiles are normally provided with groove arrangements adaptedto receive flanges of the grid of profiles. Present grove arrangements typicallyallow lifting and lateral displacement of ceiling tiles. Typical ceiling systemsmay provide concealed mounting, i.e. the groove arrangements of the ceilingtiles being such arranged that the grid of profiles become concealed. Theseceiling systems may be complex to install and the edges of the ceiling tilesmay be fragile and thus easily harmed during handling. Also disassembly ofan installed suspended ceiling system may be cumbersome requiring carefulmanipulation of each ceiling tile for enabling dismounting. ln US2011146183 a foldable ceiling tile for providing an inclination of aceiling tile is disclosed.
Summary of the invention ln view of that stated above, the object of the present invention is to provide asuspended ceiling system that reduces the possibility of weakened sideedges.
Another object is to provide a suspended ceiling system reducingcomplexity of mounting and/or dismounting ceiling tiles.
To achieve at least one of these objects and also other objects that willbe evident from the following description a suspended ceiling system havingthe features defined in claim 1 and a method for installation ofa suspendedceiling system having the features defined in claim 7 are provided accordingto the present invention. Preferred embodiments of the suspended ceilingsystem and the method will be evident from the dependent claims.
According to a first aspect of the present inventive concept, there isprovided a planar suspended ceiling system comprising a ceiling tile having afront side, a rear side and at least one side edge extending between the frontside and the rear side, the ceiling tile comprising an acoustical absorbingbody, and a front cover arranged at the front side of the ceiling tile, wherein a slit is provided extending across the entire rear side of theacoustical absorbing body thereby dividing said acoustical absorbing bodyinto a first and a second body section, and having a depth such that theceiling tile is foldable along the slit with the front cover acting as a joint, wherein the at least one side edge is provided with a pair of groovesarranged in an opposing manner on opposite sides of the slit and extending inparallel with the slit, and a grid of profiles supporting said ceiling tile in a planar, non-folded statein which flanges of the grid of profiles extend into the grooves therebysupporting the ceiling tile.
The suspended ceiling system thus comprises a foldable ceiling tilewhich reduces the complexity of installing the ceiling system. Complexity ofmounting is reduced by the system being installable without additional tools.The mounting is performed with a simple act of unfolding the folded ceiling tileinto its position in the grid of profiles. Hence the proposed ceiling system willallow for a simple mounting of ceiling tiles. lt follows that the disassemble ofthe ceiling system is of the same simple character. The grooves at theopposing portions of the at least one side edge may be formed by a singleelongated recess. Thereby the cost and time for manufacturing of the ceilingtiles may be reduced.
A possible embodiment of the concept is that the ceiling tile maycomprise a compressed fiber material such as glass wool. The compressedfiber material may enhance the acoustical insulation or absorption capacity ofthe ceiling tile. Further, compressed fiber material may enable a variety ofproportions of the ceiling tiles due to the weight of the material.
The grid of profiles of the planar ceiling system may further have aninverted T-shape, thus enabling the use of present commonly used grid ofprofiles for mounting ceiling tiles. Hence the manufacturing process may besimplified.
Another possible embodiment of the system is that the front cover maycomprise a woven or nonwoven glass fiber fabric. Glass fiber fabric mayprovide the ceiling system with sturdiness and may expand the life-span ofthe ceiling system. The use of a glass fabric may enable the ceiling tiles to befolded and unfolded without leaving visible tracks of the slits in the installedceiling.
The ceiling tiles may further be comprised such that the front cover isglued to the acoustical absorbing body. By using glue to attach the front coverto the acoustical body, the manufacturing process may be time reduced.Previously used manufacturing processes may further be used since glue is acommon method for attachment.
To avoid visibility of the grid of profiles in an installed ceiling, thegrooves of the ceiling tile may have a configuration enabling concealedmounting.
According to a second aspect of the inventive concept, there isprovided a method for installation of a suspended ceiling system comprising aceiling tile having a front side, a rear side and at least one side edgeextending between the front side and the rear side, and a grid of profilescomprising flanges for supporting the ceiling tile, the ceiling tile comprising anacoustical absorbing body, and a front cover arranged at the front side of theceiling tile, wherein a slit is provided extending across the entire rear side ofthe acoustical absorbing body thereby dividing said acoustical body into a firstand a second body section, and having a depth such that the ceiling tile isfoldable along the slit with the front cover acting as a joint, wherein the at least one side edge is provided with a pair ofgrooves arranged in anopposing manner on opposite sides of the slit and extending in parallel withthe slit, the method comprising: installing the grid of profiles in a room of a building, mounting the ceiling tile in the grid of profiles by arranging the ceiling tile in a folded state by folding the ceiling tile alongthe slit with the front cover acting as a joint, directing an apex of the folded ceiling tile in an upward direction, advancing the folded ceiling tile from below to position in which thegrooves are aligned with an opposing pair of flanges of the grid of profiles,and straightening the folded ceiling tile to a planar, non-folded state suchthat the flanges are received by the grooves of the ceiling tile.
The foldable ceiling tile may be mounted without additional tools, thusreducing the complexity of mounting the ceiling tile into the grid of profiles.
The ceiling tile may be displaced and moved around with a reducedrisk of weakening the side edges.

Description of Embodiments The present invention will now be described more fully hereinafter withreference to the accompanying drawings, in which currently preferredembodiments of the invention are shown. lt is to be understood that thepresented figures are to illustrate a close view of an example of the inventiveconcept. The figures are not designed to any certain scale, and any otherproportions than disclosed in the drawings will be obvious to the skilledperson. This invention may, however, be embodied in many different formsand should not be construed as limited to the embodiments set forth herein;rather, these embodiments are provided for thoroughness and completeness,and fully convey the scope of the invention to the skilled person.
Fig 1 illustrates mounted ceiling tiles 10 in a grid of profiles 11. The gridof profiles 11 comprises main runners 12 and cross girders 13 having a U-shaped cross section. The grid of profiles 11 is suspended from a buildingstructure by suspension means (not shown). The main runners 12 haveflanges 7 for providing support to the ceiling tiles 10. The main runners 12may have an inverted T-shape. The main runners 12 are arranged such that aceiling tile 10 fits, in a planar, non-folded state, in the space defined betweentwo adjacent main runners 12. Each cross girder 13 is provided with spacedapart slots enabling mounting of the cross girder 13 on top of, and thus at anelevated level, main runners extending in parallel. The cross girders 13 thusprovide rigidity to the grid of profiles 11 and assure the main runners 12 arespaced apart in a fixed manner while at the same time not occupying thespace defined between each pair of adjacent main runners 12.
Fig 2 illustrates a ceiling tile 10 mounted in the space defined betweentwo main runners 12 of a grid of profiles 11. The ceiling tile 10 has a front side1 intended to face the interior of a room and a rear side 2, and at least oneside edge extending between the front side 1 and the rear side 2. ln theshown embodiment, the ceiling tile 10 comprises four side edges.
The ceiling tile 10 comprises a front cover 3 and an acousticalabsorbing body 4.
The front cover 3 is arranged at the front side 1 of the ceiling tile 10.The front cover 3 may be arranged to the acoustical absorbing body 4 withattaching means, such as glue.
The front cover 3 comprises a material that is foldable and maycomprise a woven or nonwoven glass fiber fabric.
The acoustical absorbing body 4 may comprise a compressed fibermaterial such as glass wool. lt is to be understood that the acousticalabsorbing body 4 may comprise other materials.
The acoustical absorbing body 4 is provided with a slit 5. The slit 5extends across the entire rear side 2 of the ceiling tile 1. The slit 5 thusdivides the acoustical absorbing body 4 into a first and second body section4a, 4b. The slit 5 has a depth such that the ceiling tile 10 is foldable along theslit 5 with the front cover 3 acting as a joint between the first and second bodysection 4a, 4b.
Opposing portions of the at least one side edge of the ceiling tile 10 areprovided with each a groove 6. As mentioned above, the shown embodimentof the ceiling tile 10 comprises four side edges, and in this case the opposingportions of the at least one side edge are represented by a first side edge andan opposing second side edge.
Each groove 6 is configured such that the flange 7 of a profile extendsinto or is received by the groove 6 when the ceiling tile 10 is mounted. Eachgroove 6 may be configured as a single elongated recess. Further it is to beunderstood that the grooves 6 may be configured differently. lt is also to beunderstood that the groove 6 may be configured to restrict any substantiallifting or lateral displacement of the ceiling tile.
The groove 6 may further be configured such that when mounting theceiling tiles 10, the grid of profiles 11 may become concealed. ln the planar non-folded state of the ceiling tile 10, the flanges 7 of thegrid of profiles extend into the grooves 6 thereby providing support for theceiling tile 10. When in the planar non-folded state, a stopper may bearranged in the slit 5, thus defining the non-folded state of the ceiling tile 10 inthe mounted non-folded position such that sagging is counteracted, which willbe described below more in detail.
Fig 3 illustrates the process of mounting the ceiling tile 10 in the grid ofprofiles. The process is started by arranging the ceiling tile 10 in a foldedstate. When folding the ceiling tile 10 along the slit 5, the front cover 3 acts asa joint.
To mount the ceiling tile 10 into the grid of profiles 11, an apex of thefolded ceiling tile 10 is to be in an upward direction and then the folded ceilingtile 10 is advanced from below into the space defined between two adjacentmain runners 12 of the grid of profiles. The folded ceiling tile 10 is advancedto a position in which the groves 6 are aligned with the opposing pair offlanges 7 of the grid of profiles 11. Subsequently, the ceiling tile is unfolded orflattened, thus allowing the flanges 7 to be received by and to extend into thegrooves 6 of the ceiling tile 10. When straightening the folded ceiling tile 10 tothe planar state, the flanges 7 consequently extend into correspondinggrooves 6 thereby enabling the grid of profiles to support the ceiling tile 10.
The ceiling tiles 10 may be dismounted or removed in a reversedprocedure to the installing. To remove a ceiling tile 10, the part of the ceilingtile 10 comprising the slit 5 may be pressed in an upward direction, causingthe ceiling tile 10 to fold along the slit 5 with the front cover acting as a joint.As a consequence, the flanges of the grid of profiles will be retracted from thegrooves and the ceiling tile will become disengaged. By maintaining theceiling tile 10 in a folded state, the ceiling tile may be removed by movementin a downward direction from the grid of profiles 11.
The slit 5 extends in a straight extension across the entire rear surfaceof the ceiling tile 10 and has a depth which essentially corresponds to thethickness of the acoustical absorbing body 4 such that the ceiling tile 10foldable with the front cover acting as a joint. The slit 5 may be configured inmany different ways as illustrated in Figs 4a-e.
For instance, the slit 5 may, as illustrated in Fig 4a, be a simpleelongated cut having no essential width.
Alternatively, the slit 5 may be formed as an elongated recess, asillustrated in Figs 4b and 4d, having a certain width. Such a slit 5 may forinstance be formed by a sawing or milling operation. The slit 5 formed as a recess thus provides a gap 5b spanning between the first and second bodysection 4a, 4b of the acoustical absorbing body 4.
The recess may as shown in Figs 4b and 4d have a rectangular or atriangular cross section, respectively. A rectangular cross section will result ina more undefined joint axis, which may counteract formation folding marks ortracks in the front cover. On the other hand, a triangular cross section resultsin a well-defined folding axis, which may promote controlled folding of theceiling tile.
According to another embodiment, a stopper 5a may be arranged inthe slit as shown if Figs 4c and 4e.
The stopper 5a is arranged to clearly define the non-folded state of theceiling tile 10 and to prevent sagging in said non-folded state.
The stopper 5a may further be arranged to act as a biasing elementand may in this case for instance be formed as a spring element. Hereby, therisk for sagging may be further reduced. lt will be appreciated that the present invention is not limited to theembodiments shown. Several modifications and variations are thusconceivable within the scope of the invention which thus is exclusively definedby the appended claims.
