Definitions
- the present invention relates to a ceiling tile unit and a method for forming such a ceiling tile unit.
- the ceiling tile unit comprises a groove and a guide adapted to form a fold guidance for inclination of a first tile body section in relation to a second tile body section.
- Suspended ceilings can be installed in many different types of buildings for various reasons, for example 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.
- Suspended ceilings often comprise tiles and a supporting structure.
- the supporting structure normally comprises supporting profiles, which are arranged in a grid defining compartments for individual tiles or groups of tiles.
- the tiles may have sound-absorbing and/or sound-insulation properties in order to improve the acoustic environment of the room.
- the tiles for instance, may be made of a compressed fibre material such as mineral wool.
- the tiles may also be made of gypsum.
- plasterboards and a filler material may be used to visually cover the ventilation tube. This task is time-consuming and the result may not match the visual impression of the rest of the suspended ceiling.
- ceiling tiles being pre-formed to a specific curvature for this purpose.
- These tiles especially tiles made of a mineral fibre material, are pressed to a specific shape and curvature.
- These tiles may have a cross-sectional shape corresponding to a segment of a circle, or be essentially S- shaped or L-shaped in cross-section.
- Common for these tiles is that they have a large radius of curvature and a large portion of the tile is curved, which may not be desirable from an architectural or aesthetical point of view.
- a pre-formed curved ceiling tile is considerably more expensive.
- the tiles are formed and pressed to the desired shape during manufacture, they are also space requiring during transport and distribution.
- ceiling tiles having a glass wool core being bendable to a desired shape when mounting the tile to the support structure. Similar to ceiling tiles of the type described above, these ceiling tiles are only bendable to a large radius of curvature. In addition, these ceiling tiles must be attached to the support profile by clips. In order to maintain the desired shape of the profile, a clip must be fixed at every 100-300 mm depending of the radius of curvature, which is a time-consuming task.
- a further object is to provide a ceiling tile unit which enables forming of small radius of curvature and which enables efficient transportation and distribution of the tile unit.
- a ceiling tile unit comprising a tile body made of mineral fibre material, a surface layer and a guide.
- the tile body has a front side, a rear side and at least one side edge.
- the surface layer is arranged on said front side of said tile body.
- a groove is provided in said rear side of said tile body dividing said tile body into a first tile body section and a second tile body section.
- the guide is adapted to form a fold guidance for inclination of said first tile body section in relation to said second tile body section by folding about an axis parallel to the longitudinal extension said groove.
- a ceiling tile unit is meant a set comprising the tile body, the surface layer and the guide.
- the guide may be provided separately from the tile body, or may be provided together with the tile body.
- An advantage of the present invention is that the tile unit can be delivered and transported in a flat state. Thereby, the tile unit requires no extra space during transportation compared to a conventional flat tile. Since the tile unit may be transported in a flat state, the risk for damages caused by the transport is reduced. Not until the tile unit is to be mounted in a specific room the first tile body section is inclined about the axis in relation to the second tile body.
- the guide is adapted to guide the position and direction of the folding between the first and second tile body portions and to relieve the forces affecting the surface layer when inclining the second tile body portion in relation to the first tile body portion. Furthermore, the guide strengthens the transition between the first and second tile body sections and improves the impact resistance of the transition.
- the tile unit offers great flexibility.
- a ceiling tile unit having a shape and inclination adjusted to accommodate a specific detail of a room may be formed.
- the architect for example, is free to create a specific shape of the tile unit without having to select between a limited numbers of pre-formed tiles.
- the flexibility includes varying the angle of inclination, the position of the groove, the number and relative positions of the inclinations, the radius of curvature etc.
- a horizontal portion of the suspended ceiling may extend from any position along the extension of the first tile body portion. It is not necessary that the horizontal portion of the suspended ceiling starts at the end of the first tile body portion. Thereby, the level of the horizontal portion of the suspended ceiling is variable.
- a further advantage is that it is possible to obtain a small radius of curvature when forming the inclination between the first and second tile body sections.
- the transition between the first and second tile body sections may be restricted to a small area. It is thus possible to obtain a distinct transition between the first and second tile body sections.
- the groove may be formed in connection with the manufacturing of the tile body, or may be formed just before mounting the tile unit. If the groove is formed on the building site, adjustments to the specific room are possible by varying the number of grooves and the position of the groove or grooves.
- An inclined tile unit according to the present invention requires no clips in order to maintain its shape and inclination. Once inclined and suspended by a supporting structure, the tile unit will maintain its shape. Thereby, the time-consuming task of attaching clips at certain distance from each other along the edge of the tile unit is avoided.
- the tile unit is comparably more stable and the risk that the tile unit becomes damaged by an object making contact with the tile unit is reduced. Since no clips are required, the tile unit is easily demountable.
- a ceiling tile unit according the present invention is less expensive since it is formed from a conventional ceiling tile body.
- the guide may comprise a crease formed in said surface layer.
- the crease such as a crease line reduces the risk that the surface layer cracks or splits when the first tile body section is inclined in relation to the second tile body section. Thereby, folding the first tile body in relation to the second tile body is facilitated and the visual impression of the folding is improved. Further, the crease forms a distinct transition between the first and second tile body sections.
- the crease may be formed by means of a knife or by means of a tool compressing a portion of the surface layer.
- the crease may be formed just before mounting the tile unit, thereby allowing flexibility. Alternatively, the crease may be formed in connection to the manufacturing of the tile body.
- the guide may comprise a guide body of a compressible material, the guide body being adapted to be arranged in the groove.
- the guide body of the compressible material forms guidance for folding and a smooth transition between the first and second tile body sections. Further, the guide body protects and strengthens the surface layer in the transition between the first and second tile body sections.
- the guide may comprise a profile insertable in said groove.
- the profile reduces the risk that the surface layer cracks or splits when the first tile body section is inclined in relation to the second tile body section. Furthermore, the profile improves the strength and rigidity of the folded portion of the tile unit. The risk is reduced that the tile unit is damaged if an object hits the folded portion.
- the profile may be provided in the same package as the tile body or may be provided separately. Nevertheless, the profile, the tile body and the surface layer form a ceiling tile unit irrespectively if they are provided in the same package or not.
- the profile may be used in combination with a crease. Depending of the desired radius of curvature and properties of surface layer, it may be advantageous to form a crease line and insert a profile in the groove.
- the profile may at least be partially enclosed by the tile body when inserted in said groove and when the first tile body section is inclined in relation to the second tile body section. Thereby, the profile cannot be separated from the tile unit when being mounted.
- the profile may form part of a supporting grid for supporting said tile body.
- the tile unit is supported by the profile also used to form the guide. Consequently, it is possible to suspend the profile to the soffit or as a part of the supporting grid and then arrange the tile unit about the profile.
- the surface layer may comprise a layer of paint.
- the front surface of the ceiling tile body adapted to be faced towards the interior of a room is usually coated by a layer of paint. Further, the surface layer may be air-permeable.
- the groove may have a depth corresponding to the thickness of the tile body.
- the ceiling tile unit may further comprise an angle bar for locking the first tile body section in relation to the second tile body section in an inclined position.
- the angle bar secures the tile unit in its inclined position.
- the angle bar may also be used to attach two adjacent tile units to each other.
- the profile may comprise protrusions forming the angle bar.
- the ceiling tile unit may further comprise an additional groove provided in said rear side of said tile body, said groove and said additional groove dividing said tile body into said first tile body section, said second tile body section and a third tile body section, and wherein an additional guide may adapted to form a fold guidance for inclination of said third tile body section in relation to said first tile body section by folding about an axis being parallel to said additional groove.
- an additional guide may adapted to form a fold guidance for inclination of said third tile body section in relation to said first tile body section by folding about an axis being parallel to said additional groove.
- a Z-shaped tile unit may be formed, or part of box may be formed. Forming more than one groove and guide allows further adaptation to the architecture of a specific room.
- the groove may have a square cross section and may have a width corresponding to a thickness of the tile body.
- the surface layer covers a side edge of the second tile body section.
- a suspended ceiling comprising at least one ceiling tile unit of the above described type.
- the suspended ceiling incorporates all the advantages of the inventive ceiling tile unit, which previously has been discussed. Thereby, the previous discussion is applicable also for the inventive suspended ceiling.
- a method for forming a ceiling tile unit comprises:
- the method incorporates all the advantages of the inventive ceiling tile unit, which previously has been discussed. Thereby, the previous discussion is applicable also for the inventive method.
- the method is advantageous since the step of forming the groove may be performed both in connection with the manufacturing of the tile body or just before the tile unit is to be mounted in a building, thereby offering flexibility and adjustment possibilities.
- the guide may be provided as a part of the tile body or may be provided as a separate part which is to be arranged in the tile body before the first tile body section is to be inclined in relation to the second tile body section.
- the method may further comprise inclining said first tile body section in relation to said second tile body section about said axis.

Description
- The present invention relates to a ceiling tile unit and a method for forming such a ceiling tile unit. The ceiling tile unit comprises a groove and a guide adapted to form a fold guidance for inclination of a first tile body section in relation to a second tile body section.
- Suspended ceilings can be installed in many different types of buildings for various reasons, for example 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.
- Suspended ceilings often comprise tiles and a supporting structure. The supporting structure normally comprises supporting profiles, which are arranged in a grid defining compartments for individual tiles or groups of tiles. The tiles may have sound-absorbing and/or sound-insulation properties in order to improve the acoustic environment of the room. In order to obtain a relatively lightweight ceiling with satisfactory sound absorption, the tiles, for instance, may be made of a compressed fibre material such as mineral wool. The tiles may also be made of gypsum.
- Sometime it is desirable to create a smooth transition between different levels of the suspended ceiling, for example to accommodate various installations such as ventilation equipment in the ceiling void, or to achieve a special effect of the suspended ceiling. It may also be desirable to create a smooth transition between a wall and the suspended ceiling or to create a special curvature of the suspended ceiling.
- In order to hide for example a ventilation tube, plasterboards and a filler material may be used to visually cover the ventilation tube. This task is time-consuming and the result may not match the visual impression of the rest of the suspended ceiling.
- Alternatively, there is provided ceiling tiles being pre-formed to a specific curvature for this purpose. These tiles, especially tiles made of a mineral fibre material, are pressed to a specific shape and curvature. These tiles may have a cross-sectional shape corresponding to a segment of a circle, or be essentially S- shaped or L-shaped in cross-section. Common for these tiles is that they have a large radius of curvature and a large portion of the tile is curved, which may not be desirable from an architectural or aesthetical point of view. Further, compared to the cost of a conventional ceiling tile, a pre-formed curved ceiling tile is considerably more expensive.
- Since the tiles are formed and pressed to the desired shape during manufacture, they are also space requiring during transport and distribution.
- As an alternative, there is provided ceiling tiles having a glass wool core being bendable to a desired shape when mounting the tile to the support structure. Similar to ceiling tiles of the type described above, these ceiling tiles are only bendable to a large radius of curvature. In addition, these ceiling tiles must be attached to the support profile by clips. In order to maintain the desired shape of the profile, a clip must be fixed at every 100-300 mm depending of the radius of curvature, which is a time-consuming task.
- It is an object of the present invention to provide a ceiling tile unit and a method for forming such a ceiling tile unit which facilitate forming of an inclined tile unit. A further object is to provide a ceiling tile unit which enables forming of small radius of curvature and which enables efficient transportation and distribution of the tile unit.
- This and other objects and advantages that will be apparent from the description have been achieved by a ceiling tile unit comprising a tile body made of mineral fibre material, a surface layer and a guide. The tile body has a front side, a rear side and at least one side edge. The surface layer is arranged on said front side of said tile body. A groove is provided in said rear side of said tile body dividing said tile body into a first tile body section and a second tile body section. The guide is adapted to form a fold guidance for inclination of said first tile body section in relation to said second tile body section by folding about an axis parallel to the longitudinal extension said groove.
- With a ceiling tile unit is meant a set comprising the tile body, the surface layer and the guide. The guide may be provided separately from the tile body, or may be provided together with the tile body.
- An advantage of the present invention is that the tile unit can be delivered and transported in a flat state. Thereby, the tile unit requires no extra space during transportation compared to a conventional flat tile. Since the tile unit may be transported in a flat state, the risk for damages caused by the transport is reduced. Not until the tile unit is to be mounted in a specific room the first tile body section is inclined about the axis in relation to the second tile body.
- The guide is adapted to guide the position and direction of the folding between the first and second tile body portions and to relieve the forces affecting the surface layer when inclining the second tile body portion in relation to the first tile body portion. Furthermore, the guide strengthens the transition between the first and second tile body sections and improves the impact resistance of the transition.
- Since the groove may be arranged at any position on the tile body, the tile unit offers great flexibility. By varying the position and shape of the groove, a ceiling tile unit having a shape and inclination adjusted to accommodate a specific detail of a room may be formed. The architect, for example, is free to create a specific shape of the tile unit without having to select between a limited numbers of pre-formed tiles. The flexibility includes varying the angle of inclination, the position of the groove, the number and relative positions of the inclinations, the radius of curvature etc.
- Another advantage compared to a pre-formed ceiling tile having a large radius of curvature is that a horizontal portion of the suspended ceiling may extend from any position along the extension of the first tile body portion. It is not necessary that the horizontal portion of the suspended ceiling starts at the end of the first tile body portion. Thereby, the level of the horizontal portion of the suspended ceiling is variable.
- A further advantage is that it is possible to obtain a small radius of curvature when forming the inclination between the first and second tile body sections. The transition between the first and second tile body sections may be restricted to a small area. It is thus possible to obtain a distinct transition between the first and second tile body sections.
- It is to be understood that the groove may be formed in connection with the manufacturing of the tile body, or may be formed just before mounting the tile unit. If the groove is formed on the building site, adjustments to the specific room are possible by varying the number of grooves and the position of the groove or grooves.
- Mounting a ceiling tile unit according to the present invention is easy and fast compared to the prior art solutions. When the groove and guide are provided, the tile unit is ready to be mounted and no additional step is required.
- An inclined tile unit according to the present invention requires no clips in order to maintain its shape and inclination. Once inclined and suspended by a supporting structure, the tile unit will maintain its shape. Thereby, the time-consuming task of attaching clips at certain distance from each other along the edge of the tile unit is avoided. The tile unit is comparably more stable and the risk that the tile unit becomes damaged by an object making contact with the tile unit is reduced. Since no clips are required, the tile unit is easily demountable.
- Compared to a pre-formed ceiling tile, a ceiling tile unit according the present invention is less expensive since it is formed from a conventional ceiling tile body.
- The guide may comprise a crease formed in said surface layer. The crease such as a crease line reduces the risk that the surface layer cracks or splits when the first tile body section is inclined in relation to the second tile body section. Thereby, folding the first tile body in relation to the second tile body is facilitated and the visual impression of the folding is improved. Further, the crease forms a distinct transition between the first and second tile body sections. The crease may be formed by means of a knife or by means of a tool compressing a portion of the surface layer. The crease may be formed just before mounting the tile unit, thereby allowing flexibility. Alternatively, the crease may be formed in connection to the manufacturing of the tile body.
- The guide may comprise a guide body of a compressible material, the guide body being adapted to be arranged in the groove. The guide body of the compressible material forms guidance for folding and a smooth transition between the first and second tile body sections. Further, the guide body protects and strengthens the surface layer in the transition between the first and second tile body sections.
- The guide may comprise a profile insertable in said groove. The profile reduces the risk that the surface layer cracks or splits when the first tile body section is inclined in relation to the second tile body section. Furthermore, the profile improves the strength and rigidity of the folded portion of the tile unit. The risk is reduced that the tile unit is damaged if an object hits the folded portion.
- Additionally, by varying the cross-sectional shape of the profile, different radius of curvature and shapes of the transition between the first and second tile body sections are obtainable.
- It is to be understood that the profile may be provided in the same package as the tile body or may be provided separately. Nevertheless, the profile, the tile body and the surface layer form a ceiling tile unit irrespectively if they are provided in the same package or not.
- The profile may be used in combination with a crease. Depending of the desired radius of curvature and properties of surface layer, it may be advantageous to form a crease line and insert a profile in the groove.
- The profile may at least be partially enclosed by the tile body when inserted in said groove and when the first tile body section is inclined in relation to the second tile body section. Thereby, the profile cannot be separated from the tile unit when being mounted.
- The profile may form part of a supporting grid for supporting said tile body. Thereby, the tile unit is supported by the profile also used to form the guide. Consequently, it is possible to suspend the profile to the soffit or as a part of the supporting grid and then arrange the tile unit about the profile.
- The surface layer may comprise a layer of paint. The front surface of the ceiling tile body adapted to be faced towards the interior of a room is usually coated by a layer of paint. Further, the surface layer may be air-permeable.
- The groove may have a depth corresponding to the thickness of the tile body. Thereby, folding of the first tile body in relation to the second tile body is further facilitated since the material of the tile body is removed in this portion.
- The ceiling tile unit may further comprise an angle bar for locking the first tile body section in relation to the second tile body section in an inclined position. The angle bar secures the tile unit in its inclined position. The angle bar may also be used to attach two adjacent tile units to each other.
- As an alternative, the profile may comprise protrusions forming the angle bar.
- The ceiling tile unit may further comprise an additional groove provided in said rear side of said tile body, said groove and said additional groove dividing said tile body into said first tile body section, said second tile body section and a third tile body section, and wherein an additional guide may adapted to form a fold guidance for inclination of said third tile body section in relation to said first tile body section by folding about an axis being parallel to said additional groove. Thereby, a Z-shaped tile unit may be formed, or part of box may be formed. Forming more than one groove and guide allows further adaptation to the architecture of a specific room.
- The groove may have a square cross section and may have a width corresponding to a thickness of the tile body. When the first tile body section is inclined in relation the second tile body section, the surface layer covers a side edge of the second tile body section.
- According to a second aspect of the invention, a suspended ceiling comprising at least one ceiling tile unit of the above described type is provided. The suspended ceiling incorporates all the advantages of the inventive ceiling tile unit, which previously has been discussed. Thereby, the previous discussion is applicable also for the inventive suspended ceiling.
- According to a third aspect of the invention, a method for forming a ceiling tile unit is provided. The method comprises:
- providing a ceiling tile unit comprising a tile body made of mineral fibre material and a surface layer, said tile body having a front side, a rear side and at least one side edge, and said surface layer being arranged on said front side of said tile body,
- forming a groove in said rear side of said tile body dividing said tile body into a first tile body section and a second tile body section,
- providing a guide adapted to form a fold guidance for inclination of said first tile body section in relation to said second tile body section by folding about an axis parallel to the longitudinal extension of said groove.
- The method incorporates all the advantages of the inventive ceiling tile unit, which previously has been discussed. Thereby, the previous discussion is applicable also for the inventive method. In addition to the advantages already discussed, the method is advantageous since the step of forming the groove may be performed both in connection with the manufacturing of the tile body or just before the tile unit is to be mounted in a building, thereby offering flexibility and adjustment possibilities. The guide may be provided as a part of the tile body or may be provided as a separate part which is to be arranged in the tile body before the first tile body section is to be inclined in relation to the second tile body section.
- The method may further comprise inclining said first tile body section in relation to said second tile body section about said axis. The step of inclining the first tile body section in relation to the second tile body section may be performed separately from the forming of tile unit. During distribution, the tile unit is in its flat and unfolded state, but when mounting the tile unit, the tile unit is inclined.
