Description
- The present invention relates to a suspended ceiling system, and more particular to such a suspended ceiling system comprising a polygon-shaped ceiling tile and a grid of profiles supporting the ceiling tile.
- Ceilings being suspended from a ceiling structure, which henceforward is referred to as suspended ceilings, can be installed in many different types of buildings for various reasons. Examples of reasons are to absorb sound, to reflect light, to lower the ceiling height or to conceal installations such as cable arrangements, ventilation equipment, lighting installations and other devices arranged in the space between the suspended ceiling and the ceiling structure of a building.
- A common type of suspension is to use a grid of profiles for suspending a plurality of ceiling tiles. The grid of profiles is suspended from a ceiling structure. The profiles are arranged to support and thus uphold the ceiling tiles. The profiles can for example be formed by T-beams with laterally extending flanges, wherein the ceiling tiles are placed so that the flanges support the edges of the ceiling tiles. The ceiling tiles are thus embedded in the grid of profiles.
- As an alternative to suspension of ceiling tiles by means of a grid of profiles, free-hanging units of ceiling tiles forming ceiling islands are one way of creating acceptable acoustic environments. The ceiling tiles may have sound-absorbing properties. An advantage with free-hanging ceiling tiles are that they often are regarded as more esthetically appealing due to their exposed edges and floating impression, when compared to ceiling tiles being embedded in a grid of profiles.
- Free-hanging ceiling tiles can be installed in large, noisy environments such as open-plan areas, restaurants, shopping centers etc., close to working areas or other locations where acoustical treatment is needed in order to achieve suitable conditions for communication, concentration or recovery.
- Free-hanging units can also be used as a complement to an overall suspended ceiling in order to improve the acoustic environment with a reduction of the sound level and a diminishing of sound as distance increases.
- Free-hanging ceiling tiles may be mounted by means of suspension members connecting the ceiling tiles to a ceiling structure. This mounting causes the free-hanging ceiling tiles to be sensitive to air flows which may set the ceiling tiles in motion.
- The ceiling tiles may be arranged according to various designs depending on the application. In order to achieve a particular ceiling arrangement by means of free-hanging tiles suspended by suspension members, a precise and accurate mounting process is required. Each ceiling tile, typically being suspended by four suspension members, needs to be aligned with adjacent ceiling tiles in order to achieve the desired design. This is particular important for designs in which it is easy for the human eye to spot deviations, which makes the ceiling appear defective and/or incorrectly mounted. An example of such a sensitive design is ceiling tiles being arrange adjacent to each other and distanced with an even distance. Even a tiny deviation from this distance makes the ceiling tiles appear slanted in relation to each other. An esthetically appealing configuration is to let the distance be equal to the thickness of the ceiling tile. Thus, the distance may be quite small which makes a deviation even more easy to spot. Small distances between the ceiling tiles are also desirable in order to increase the acoustic performance, i.e. the sound absorption capacity, of the ceiling. In this case, a high cover ratio of the ceiling tiles is desired which is achieved by having a small distance between the ceiling tiles.
- Consequently, when designing a suspended ceiling system, one has to choose between embedded ceiling tiles providing an easier alignment and a more stable system, and free-hanging ceiling tiles providing a more appealing esthetical appearance and higher design freedom.
- EP2902559 discloses a ceiling system comprising a grid of profiles having a plurality of fixing points, ceiling tiles each provided with attachment points on a rear surface thereof and connections member each connected to a fixing point of grid of profiles, wherein the connection members are releasably connectable to the attachment points in response to pushing the ceiling tiles in an upward direction. Hereby a ceiling system is provided with a high degree of design freedom having the controlled and stable mounting enabled by the grid of profiles and at the same time the esthetic value of free-hanging ceiling tiles. However, in some cases the ceiling system may be associated with an increased cost and may be time consuming to install.
- DE2457806 discloses a ceiling system in which a joint between two adjacent ceiling panels is provided with a cover strip. Each ceiling panel is provided with groove configurations extending along side edges of the ceiling tile, enabling mounting of the ceiling panels from below by a tilting movement.
- Thus, there is a need for an improved way of mounting ceiling tiles.
- It is an object of the present invention to provide an improvement over the above described techniques and prior art.
- A particular object is to provide a suspended ceiling system enabling simple and efficient mounting of the ceiling tiles in an improved manner.
- A it also an object to provide such a suspended ceiling system having the aesthetic value of a group or cluster of free-hanging ceiling tiles arranged with small gaps therebetween.
- To achieve at least one of the above objects and also other objects that will be evident from the following description, a suspended ceiling system having the features defined in claim 1 is provided according to the present invention. Preferred embodiments will be evident from the dependent claims.
- More specifically, there is provided according to the present invention a suspended ceiling system comprising a polygon-shaped ceiling tile and a grid of profiles supporting the ceiling tile. The grid of profiles defines a frame in which the polygon-shaped ceiling tile is arranged and supported by supporting flanges of the grid of profiles. The polygon-shaped ceiling tile comprises at front surface, a rear surface and at least three side edges extending between the front surface and the rear surface, wherein a side edge portion associated with each side edge comprises a top tongue, a bottom tongue, and a groove extending along the side edge portion and separating the top tongue and the bottom tongue. The top tongues comprise engagement surfaces resting on the supporting flanges of the grid of profiles. A distal end of each top tongue extends beyond a distal end of the bottom tongue such that a bottom section of the polygon-shaped ceiling tile comprising the bottom tongue and the groove of each side edge portion is insertable from above into the frame defined by the grid of profiles.
- Hereby, a suspended ceiling enabling simple and efficient mounting of the ceiling tiles is provided.
- The provision of top tongues having distal ends extending beyond the distal ends of the associated bottom tongues enables insertion from above of the ceiling tile into the frame of the grid of profiles such that that the bottom portion of the ceiling tile is passed through the frame and such that the engagement surfaces of the top tongues are placed on the supporting flanges.
- The provision of a groove extending along each side edge portion and separating the top tongue from the bottom tongue enables the formation of a shadowed void extending along the side edges and thus encircling the front surface of the ceiling tile. Hereby, the ceiling tile may have the aesthetic value of a group or cluster of free-hanging ceiling tiles arranged with small gaps therebetween while still being installed in a frame of a grid of profiles.
- Each frame of the grid of profiles is configured for reception of one ceiling tile.
- The ceiling tile may be made of a porous material.
- The ceiling tile may have sound or acoustical absorbing properties.

By the provision of a first coating on the front surface having a light reflectance above 0.8 (for instance a white paint) the contrast between the front surface and the shadowed void may be enhanced, which will increase the impression of the ceiling tile being free-hanging.
- By “light reflectance” is in this application meant the proportion of incident visible light being reflected. Thus, a front surface provided with a coating having a light reflectance above 0.8 will reflect above 80% of the incident visible light.
- Each side edge portion may comprise a side edge surface adjoining the front surface and being provided with a first coating having a light reflectance above 0.8. By providing the side edges surfaces adjoining the front surface of the ceiling tile with the first coating, the thickness of the perceived free-hanging ceiling tile may correspond to the thickness of the bottom tongue.
- According to another embodiment, each side edge portion may comprise a side edge surface provided with a second coating having a light reflectance below 0.2. By providing some or all side edge surfaces with a second coating having a light reflectance below 0.2, such as a black paint, the shadowing effect of the void may be enhanced, thereby increasing the impression of the ceiling tile to be free-hanging.
- According to yet another embodiment, the front surface may be provided with a first coating and each side edge portion may comprise a side edge surface provided with a second coating, wherein the difference between the light reflectance of first coating of the front surface and the light reflectance of the second coating of the side edge surface is at least 0.5. Hereby the shadowing effect of the void may be further enhanced.
- Each supporting flange of the grid of profiles may comprise a bottom surface provided with a third coating having a light reflectance below 0.2. By providing the bottom surfaces of the supporting flanges with a third coating having a light reflectance below 0.2, such as black paint, the shadowing effect of the void may be further enhanced.

FIG. 2 , to which reference now also is made, illustrates installation of a suspendedceiling system 50 comprisingceiling tiles 10 of the type described above and a grid ofprofiles 30. - The grid of
profiles 30 is configured to be supported by a structural ceiling of a room. - The grid of
profiles 30 defines a plurality offrames 31 in which theceiling tiles 10 are arranged. Theceiling tiles 10 are supported by supportingflanges 32 of the grid ofprofiles 30. - More specifically, the supporting flanges are configured to support the
ceiling tiles 10 via the engagement surfaces 18 of thetop tongues 14 of theceiling tiles 10. - Each supporting
flange 32 may comprise abottom surface 33 provided with a third coating such as paint. The third coating may have a light reflectance below 0.2. - In the shown embodiment, the grid of
profiles 30 comprises a plurality of primary profiles extending in parallel and having an inverted T-shape with anupstanding web 34 and two supportingflanges 32 extending laterally in opposite directions. The free end of theweb 34 may be provided with a reinforcing bulb (not shown). - The grid of profiles further comprises a plurality of secondary profiles (not shown) extending transversely to the primary profiles such that the frames are defined by the primary profiles and the secondary profiles.
- Each
frame 31 is configured for reception of a single ceiling tile. - For installation of a
ceiling tile 10 in aframe 31 of the grid ofprofiles 30, theceiling tile 10 is inserted from above into theframe 31 such that theengagement surface 18 of eachtop tongue 14 comes to rest against an associated supportingflange 32 of the grid ofprofiles 30, as evident from the detached enlargement inFIG. 2 . - In the figure, the
ceiling tile 10 to the left is being lowered from above into aframe 31 defined between the left primary profile and the middle primary profile, and theceiling tile 10 to the right is arranged in a frame defined between the middle primary profile and the right primary profile. - A
distal end 19 of eachtop tongue 14 extends beyond adistal end 20 of the associatedbottom tongue 15 such that abottom section 21 of the polygon-shapedceiling tile 10 comprising thebottom tongue 15 and thegroove 16 of each side edge portion is insertable from above into and through theframe 31 defined by the grid ofprofiles 30. Thus, when theceiling tile 10 is lowered from above into theframe 31, thebottom section 21 of theceiling tile 10 will pass through theframe 31 such that the engagement surfaces 18 of thetop tongues 14 may be brought into engagement with the supportingflanges 32 of the grid ofprofiles 30 for support of theceiling tile 10. - For the embodiment shown in
FIG. 2 , theceiling tile 10 has a first width W1 as measured between the distal ends 19 of the opposing pair oftop tongues 14 and a second width W2 as measured between the distal ends 20 of the opposing pair ofbottom tongues 15. Further, distal ends 35 of two supportingflanges 32 facing each other and each associated with a respective primary profile are separated by a distance D. The first width W1 of theceiling tile 10 is greater than the distance D and the second width W2 of theceiling tile 10 is smaller than the distance D. -
FIG. 3 a-b illustrate the installation of arectangular ceiling tile 10. A grid ofprofiles 30 comprises supportingflanges 32 defining arectangular frame 31. For sake of clarity, the webs associated with the supportingflanges 32 have been left out. - In
FIG. 3 a, theceiling tile 10 is positioned above theframe 31. As evident from the figure, eachtop tongue 14 has adistal end 19 extending beyond thedistal end 20 of the associatedbottom tongue 15 whereby theceiling tile 10 may be lowered into theframe 31 such that thebottom section 21 of theceiling tile 10 may be inserted and passed through theframe 31 until the engagement surfaces 18 of thetop tongues 14 come to rest against the supportingflanges 31, as illustrated inFIG. 3 b. -
FIG. 4 illustrates an embodiment of the suspendedceiling system 50 comprisingrectangular ceiling tiles 10 installed inframes 31 defined by a grid ofprofiles 30. For sake of clarity, only the supportingflanges 32 of the grid ofprofiles 30 are illustrated. - The ceiling tiles have been installed in accordance with what has been described above, i.e. by inserting the
ceiling tiles 10 from above into theframes 31 of the grid ofprofiles 30. - The design of a
ceiling tile 10 with side edge portions each comprising atop tongue 14 and abottom tongue 15 separated by agroove 16 extending along the associatedside edge 13, wherein adistal end 19 of eachtop tongue 14 extends beyond adistal end 20 of thebottom tongue 15, results in aceiling tile 10 which is easy to install in aframe 31 of a grid ofprofiles 30. Theceiling tile 10 is simply inserted from above into theframe 31 such that thebottom section 21 of theceiling tile 10 is passed through theframe 31 and the engagement surfaces 18 of thetop tongues 15 come to rest on the supportingflanges 32. - The
groove 16 extending along each side edge portion and separating thetop tongue 14 from thebottom tongue 15 enables the formation of a shadowed void extending along the side edges and thus encircling the front surface of each ceiling tile. Hereby, an impression is created of the ceiling tiles being arranged in a free-hanging manner while still being installed in frames of a grid of profiles. - The fact that the
front surface 11 of theceiling tile 10 and, in the shown embodiment, also the adjoining side edge surfaces 17′ of the side edge portions, are provided with a first coating and the remaining side edge surfaces 17 are provided with a second coating makes it possible to further enhance the impression of theceiling tiles 10 to be installed in a free-hanging manner, despite the fact that theceiling tiles 10 are in fact arranged in aframe 31 of a gird ofprofiles 30. - The impression is enhanced by ensuring that the difference in light reflectance between the first coating and the second is at least 0.5. The first coating may have a light reflectance above 0.8 and the second coating may have a light reflectance below 0.2. The first coating may be a white paint and the second coating may be a black paint.
- In the shown embodiment, tt is thus the part of the ceiling tile provided with the first coating which form the part of the ceiling tile appearing to be installed in a free-hanging manner.
- The
bottom surface 33 of each supportingflange 32 may be provided with a third coating having a light reflectance below 0.2. - In
FIGS. 5 a, b another embodiment of theceiling tile 10 is disclosed. In this case, the polygon-shapedceiling tile 10 is triangular. Theceiling tile 10 thus comprise afront surface 11, arear surface 12 and threeside edges 13 extending between thefront surface 11 and therear surface 12. Like before, a side edge portion associated with eachside edge 13 comprises a top 14 tongue provided with anengagement surface 18, abottom tongue 15 and agroove 16 extending along theside edge 13 and separating thetop tongue 14 and thebottom tongue 15. Also, thedistal end 19 of eachtop tongue 14 extends beyond thedistal end 20 of thebottom tongue 15. Thus, theceiling tile 10 is insertable from above into aframe 31 of a grid ofprofiles 30 such that thebottom section 21 of theceiling tile 10 is passed through theframe 31 and the engagement surfaces 18 of thetop tongues 14 come to rest on the supportingflanges 32. A suspendedceiling system 50 comprisingtriangular ceiling tiles 10 of this type is illustrated inFIG. 6 . - As evident from the figures, in the shown embodiment, it is only the
front surface 11 of theceiling tile 10 that is provided with the first coating and all side edge surfaces 17 of each side edge portion is provided with the second coating. Such a configuration will create an impression of free-hanging sheets. - It will be appreciated that the present invention is not limited to the embodiments shown.
- For instance, the groove may be shaped in any desired manner, such as V- or U-shaped. The purpose of the groove is to create a void which enhances the impression of a free-hanging installation.
- Also, the groove may be utilized for additional installation. For instance, a lighting strip may be arranged in the groove.
- A suspended ceiling system comprising ceiling tiles provided with lighting strips in some or all the grooves may still be perceived as arranged in a free-hanging manner. However, for a ceiling tile provided with a lighting strip in each or all grooves, the void formed by each groove comprising a lighting strip will not be shadowed but illuminated, and as long as the contrast between front surface of each ceiling tile and the void is sufficiently strong, the impression of a free-hanging ceiling tile may be maintained.
- Further, in the embodiments described above, the side edge surfaces forming the distal ends of the top and the bottom tongues extend have an extension perpendicular to the front and rear surfaces of the ceiling tile. It is understood that these side edge surfaces may be formed differently.
- Several modifications and variations are thus conceivable within the scope of the invention which thus is exclusively defined by the appended claims.
