The present invention relates to a surface forming system intended to be supported by a structural ceiling and/or a wall of a room. The invention further relates to a method for installation of a surface forming system supported by a structural ceiling and/or wall of a room.

Technical background

Suspended ceilings, or other interior surfaces, 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 structural ceiling of a room, or to provide an aesthetically appealing surface.

It is known to install a suspended ceiling in buildings by using a grid system mounted to the ceiling to which grid system ceiling tiles are fastened.

Suspended ceilings typically consist of a plurality of tiles suspended from the structural ceiling. It is a problem to achieve well defined gaps between the tiles, and to achieve parallel side edges of adjacent tiles of suspended ceilings. It is particularly problematic to achieve well defined gaps and parallel side edges with non-planar ceilings, irregularly shaped structural ceilings, non-rectangular tiles, and/or irregularly shaped or sized tiles.

There is a need for a surface forming system supported by a structural ceiling which efficiently may be used with irregularly shaped structural ceilings, non-rectangular tiles, and/or irregularly shaped or sized tiles. Summary of the invention

It is an object of the present invention to provide an improvement over the above described techniques and prior art.

It is a further object of the present invention to provide a surface forming system intended to be supported by a structural ceiling which efficiently may be used with irregularly shaped structural ceilings, non- rectangular tiles, and/or irregularly shaped or sized tiles. According to an aspect, there is provided a surface forming system intended to be supported by a structural ceiling and/or a wall of a room. The surface forming system comprises a first tile and a second tile, each tile comprising a front major surface, an opposing back major surface and at least one edge surface extending along the perimeter of the tile and connecting the front and back major surfaces, a first connecting member and a second connecting member, each comprising a tile connector and a pivot connector, wherein the tile connector of the first connecting member and the second connecting member are connected to the first tile and the second tile, respectively, and wherein the pivot connector of the first and the second connecting members are pivotably connected to each other such that the tiles are foldable relative each other.

With such a system a surface comprising a plurality of tiles of desired shapes may be formed. Adjacent tiles may be efficiently connected with predetermined gaps and parallel side edges, even when they are part of an un-even, such as non-planar, surface, and even when the structural ceiling and/or wall is irregularly or non-planar shaped. A first connecting member and a second connecting member are efficient for connecting of adjacent tiles. The tile connectors makes it possible to connect the connecting members to tiles. The pivot connectors makes it possible to pivotably connect the connecting members, and, thus, efficiently make the tiles foldable relative to each other. The connecting members, further, Such a surface forming system with tiles being foldable relative each other provides for efficient forming of surfaces including non-planar surfaces. The surface forming system may be supported by a structural ceiling and/or a wall of a room by hinge member(s) being connectable to the structural ceiling and/or the wall of a room. It will be understood that such a system efficiently allows the surface to be formed, at least in part due to the hinge members which allows the tiles to efficiently be connected such that they form a planar or a non-planar surface with desired angling between adjacent tiles. In addition, the system provides for control of the gap between adjacent tiles. The tiles being foldable relative each other allows the tiles to adapt to desired and/or predetermined shape of the formed surface. The first and the second tile may be comprising of compressed fibre material.

The compressed fibre material may be compressed mineral fibre material.

Such compressed fibre materials provides efficient properties to the tiles.

The pivot connector of the first and the second connecting members may be pivotably connected to each other for forming a hinge joint. Such a hinge joint efficiently makes the tiles foldable relative each other. Further, the system with such a hinge joint efficiently allows adjacent tiles to be installed with parallel edge surfaces.

The hinge joint may be positioned in a space formed between the at least one edge surface of the first and the second tiles. The system with such a hinge joint efficiently allows adjacent tiles to be installed with parallel edge surfaces.

The surface forming system may further comprise a first hinge member, and the pivot connector of the first and the second connecting members may be pivotably connected to each other via the hinge member. Thus, an efficient pivotable connection between the pivot connectors may efficiently be provided.

The hinge member may be connectable to the structural ceiling and/or the wall. Thus, a surface, for example in the form of a ceiling and/or wall, may efficiently be formed. Further, the surface forming system may efficiently be supported by a structural ceiling and/or a wall of a room

The tile connector of the first and second connecting members may be inserted in a slit or groove of the at least one edge surface of the first and the second tiles, respectively, or attached to a major surface of the first and the second tiles, respectively. Thus, tiles may be connected in an efficient and predetermined manner.

Each of the first and the second connecting members may have a lip or shoulder arranged to abut the at least one edge surface of the first and the second tiles, respectively, such that a predetermined space is formed between the at least one edge surface of the first and the second tiles. The first and the second connecting members may be made of sheet structure or wire structure.

The sheet structure may be sheet metal or sheet plastic.

The wire structure may be bent metal wire or bent plastic wire or rod. Such connecting members may efficiently be produced and are durable and efficient.

One or both of the front major surface and the opposing back major surface of each of the first tile and the second tiles may be planar.

The first and the second connecting members may be made of bend metal wire, the tile connectors of the first and the second connecting members may each comprise a planar portion inserted in a slit or groove of the at least one edge surface of the first and the second tiles, respectively, and the pivot connectors of the first and the second connecting members may each comprise at least one protruding member inserted in corresponding orifices of the first hinge member whereby the pivot connector of the first and the second connecting members are pivotably connected to each other via the hinge member.

According to another aspect, there is provided a method for installation of a surface forming system supported by a structural ceiling and/or wall of a room. The method comprises attaching a first hinge member to the structural ceiling and/or wall; connecting a tile connector of a first connecting member to a first tile; connecting a tile connector of a second connecting member to a second tile; connecting a pivot connector of the first connecting member to the first hinge member; and connecting a pivot connector of the second connecting member to the first hinge member, whereby the first and second tiles are foldable relative each other by pivoting about said first hinge member.

The method may further comprise attaching a second and a third hinge member to the structral ceiling and/or wall; connecting a tile connector of a third connecting member to the first tile; connecting a tile connector of a fourth connecting member to the second tile; connecting a pivot connector of the third connecting member to the second hinge members; and connecting a pivot connector of the fourth connecting member to the third hinge member. With the method a surface comprising a plurality of tiles may efficiently be formed.

The fastening the hinge members to the structural ceiling and/or wall may be prior to the remaining steps of the method, and connecting the connecting members to the tiles may be made prior to connecting the connecting members to the hinge members.

Detailed description With the embodiments it is made possible to efficiently form a surface, such as a suspended ceiling or wall, from a plurality of tiles, wherein the surface is having a desired shape. The tiles being foldable relative each other enables efficient formation of, for example, non-planar surfaces. Further, a

predetermined gap between adjacent tiles may efficiently be realised. The surface forming system benefits from from the tiles being foldable relative each other and, thus, efficiently may adapt to a non-plain or irregularly shaped surface, and, in addition, that adjacent tiles are connected to each other with a predetermined gap.

With reference to figure 1 , a surface forming system 1 intended to be supported by a structural ceiling 2 and/or a wall 3 of a room 4 will now be discussed. The surface forming system 1 has a first tile 6a and a second tile 6b. Each tile 6a, 6b has a front major surface 8a, 8b, an opposing back major surface 10a, 10b and at least one edge surface 12a, 12b extending along the perimeter of the tile 6a, 6b and connecting the front and back major surfaces 8a,8b,10a,10b. The surface forming system 1 further has a first connecting member 14a and a second connecting member 14b, each comprising a tile connector 16a, 16b and a pivot connector 18a, 18b, wherein the tile connector 16a, 16b of the first connecting member 14a and the second connecting member 14b are connected to the first tile 6a and the second tile 6b, respectively. The pivot connector 18a, 18b of the first and the second connecting members 14a, 14b are pivotably connected to each other such that the tiles 6a, 6b are foldable relative each other. The connection of the surface forming system 1 to the structural ceiling 2 and/or a wall 3 of a room 4 is not illustrated in figure 1 .

Figure 2 illustrates a cross-section of a room 4 having a surface in the form of a suspended ceiling formed by the surface forming system 1 according to an embodiment. The surface is supported by the structural ceiling 2 and wall 3 of a room 4, by structure connectors 50a-f linking the connecing members 14a-j and the structural ceiling 2 and wall 3, although other suitable ways of supporting the surface may be used. Structure connectors 50a-f provides a fixed reference point for the tiles, and thereby allowing fastening of the tiles in a fixed relationship with the room 4. Further, the structure connectors may be designed to provide a surface with any suitable shape and essentially independent of the shape of the structural ceiling and/or wall. Alternatively, the connecing members 14 may be directly linked to the structural ceiling 2 and/or wall 3 by suitable fastening means. Such direct linking may be used, for example, if the surface formed by the tiles 6 is intended to follow the shape of the structural ceiling 2 and/or wall 3.

The embodiment discussed with reference to figure 2 illustrates that a non-planar surface, in this example a curved surface, efficiently may be formed. Although figure 2 only illustrates a curved line of the cross section of the ceiling it is realised that the surface may be curved in three dimensions. For example, the surface may be spherical, or take any suitable form. Tiles being foldable relative to adjacent tiles as a result of the pivot connectors results in efficient installation of the curved ceiling. In addition, predetermined gaps and parallel side edges between adjacent tiles may be realised. By suitable selection of structure connectors 50, and sizes and shapes of tiles, a desired shape of the surface may be formed.

According to an embodiment, the surface is supported by the structural ceiling and/or wall 2 of a room 4, by structure connectors 50 linking the connecing members 14 and the structural ceiling 2 and/or wall 3.

By selecting suitably designed structure connectors 50 and connecting them suitably to the structural ceiling 2 and/or wall 3, the form of the surface may be formed simply by installing the tiles to the connectors, and, thus, efficient installation is realised.

Different surface forming systems according to embodiments will now be described with reference to figures 3 to 6. It will be realised that different connecting membes and hinge joints may provide foldable tiles with parallel side edges, which, thus, may be used for forming surfaces of desired shapes.

With reference to figure 3, a surface forming system 1 intended to be supported by a structural ceiling 2 and/or a wall 3 of a room 4 according to an embodiment will now be discussed. In order to improve clarity, the tiles are not illustrated. The first and second connecting members 14a,b has tile connectors 16a,b and pivot connectors 18a,b. The connecting

members 14a,b according to this embodiment are made of bent metal wire defining a major portion in planes 26a, b. Although the connecting members 14a,b each is made of a single piece of bend metal wire it is realised that it may be comprised of a plurality of bent metal wires suitably connected to form the connecting member.

The pivot connectors 18a,b each comprises at least one protruding member 40a-d inserted through holes 22a-d of the hinge member 20, which hinge member 20 is made of sheet metal. Thereby, the first and the second connecting members 14a,b are foldable relative each other. The pivot connectors 18a,b are pivotably connected for forming a hinge joint. The illustrated connecting members 14a,b each has a pivot connector 18a,b each comprising two protruding members 40a-d. The tile connectors 16a,b are connectable to tiles 6a, b, which, for clarity reasons, are not illustrated in figure 3. In this embodiment, the tile connectors 16a,b are intended to be inserted in slits or grooves of the at least one edge surface 12a, b of each tiles 6a, b, respectively, similar to discussions referring to figure 4, but, alternatively, they may each be attached to a major surface of a tile.

The connecting members 14a,b have shoulders 24a, b arranged to abut edge surfaces 12a,b of the tiles, thereby predetermined spaces are formed between the edge surface 12a of the first tile 6a connected to the

first connecting member 14a and the edge surface 12b of the second tile 6b.

It is realised that according to alternative embodiments, the first and the second connecting members 14a,b may be pivotably connected to each other such that the tiles 6a,6b are foldable relative each other without a hinge member 20.

The hinge member 20, such as the hinge members 20 illustrated in figures 3 to 6, may be connectable directly to the structural ceiling 2 and/or the wall 3; or may be connecatable indirectly via a structure connector, thereby providing a fixed reference point for the tiles 6a, b, and thereby allowing fastening of the tiles 6a, b in a fixed relationship with the room 4.

With reference to figure 4, a surface forming system 1 supported by a structural ceiling 2 and/or wall 3 (not illustrated) is illustrated to indicate one embodiment of connecting a tile 6b. The system 1 is illustrated with one tile 6b, although it is realised that the system may comprise further tiles. Both connecting members 14a,b are identical, and made of bent metal wire similar to the embodiment illustrated with reference to figure 3. A part of connecting member 14b is obscured by the tile 6b. The hinge member 20 of the illustrated embodiment comprises metal wire comprising spirals, and according to this embodiment two structure connectors 50a, b are linking the connecing members 14a,b to a structural ceiling 2 and/or wall 3. The structure connector 50a, b are linked to different points of the structural ceiling 2 and/or wall 3a. The tile connector 16b of connecting member 14b is inserted into a slit 52 of the tile 6b, and shoulders 24b of connecting member 14b abuts one edge surface 12b of the tile 6b. Although only one tile, tile 6b, is illustrated to improve visibility of details of the system 1 , it will be understood from figure 4 that, thus, a predetermined space or gap efficiently is provided between tiles connected to the connectors 14a,b, as indicated by arrow 54. Further it may be noted from figure 4 that the embodiment is illustrated with part of a triangularly shaped tile 6b.

With reference to figure 5, a surface forming system 1 intended to be supported by a structural ceiling 2 and/or a wall 3 of a room 4 will now be discussed. First and second tiles 6a, 6b have not been illustrated in an attempt to improve the visibility of details of the system. I will be understood that the tile connectors 16a,b may be connected to tiles for example by being inserted in slits 52 of tiles 6a, b similarly to what is illustrated and discussed with reference to figure 4. The system 1 has a first connecting member 14a and a second connecting member 14b, both made of sheet metal. Each connecting member 14a,b has a tile connector 16a,b which is inserted into a slit 52 of the tile it connects. A corrugation 28a, b of the tile connectors 16a, b are provided for locking the tile connectors 16a,b in place when inserted into the slits. Each of the first and the second connecting members 14a,b have a lip or

shoulder 24a, b which abut the edge surface of the first and the second tiles 6a, b, respectively, such that a predetermined space is formed between the at least one edge surface of the first and the second tiles, as indicated by arrow 30. Each of the first and the second connecting members 14a,b further have pivot connectors 18a,b pivotably connected to each other such that the tiles are foldable relative each other. The pivot connectors 18a,b are connected to hinge member 20. The pivot connectors 18a,b comprise resilient clips which in part circumferes the hinge member 20 which is in the form of a spring or spiral secured to structure connector 50 linking the connecing members 14a, 14b and the not illustrated structural ceiling/wall 2. It is realised that one or both of the tile connectors 16a, b could have been attached to a major surface of the tile(s) 6a, b instead of having been inserted into slits. The connecting members 14a,b have planar portions 32a, b in a shape of a circular segment, thereby facilitating efficient insertion in the slits of the tiles 6a, b.

With reference to figure 6, first and second connecting members 14a,b and a hinge member 20 of a surface forming system 1 according to an embodiment will now be discussed. In order to improve clarity, the tiles are not illustrated. The connecting members 14a,b are made of sheet metal. The connecting members 14a,b have tile connectors 16a,b similar to the tile connectors 16a, b discussed with reference to figure 5. The tile

connectors 16a,b are intended to be inserted into slits of the tiles, or to major surfaces of the tiles. The connecting members 14a,b further have pivot connectors 18a,b connectable to the hinge member 20 by inserting through corresponding openings 34 until resilient locking members 36 snaps such that it releasably locks pivot connectors 18a,b to hinge member 20. It will be appreciated that the connecting members 14a,b thereby are pivotably connected to each other such that connected tiles are foldable relative each other.

It will be realised from the discussions above with reference to figures 1 to 6 that a surface comprising tiles, such as a suspended ceiling, efficiently may be installed. As one result of the connecting members well defined gaps between the tiles, and parallel side edges of adjacent tiles may efficiently be realised and non-planar ceilings, irregularly shaped structural ceilings, may be realised, even with non-rectangular tiles, and/or irregularly shaped or sized tiles.

The tile connector of the first and the second connecting members may be made of metal wire defining a major portion in a plane. The tile connector of the first and the second connecting members may be made of sheet metal and comprises a planar portion, preferably tapered in a plane. Thereby, efficient insertion in the slit is facilitated.

The tile connector may be profiled, such as by comprising

corrugations, for locking the tile connector in place when inserted into a slit of the tile.

The tile connector may be in/comprise the shape of a circular segment.

The tiles of a system may have any suitable form, such as cirvular, oval, squared, rectangular, pentagonal, hexagonal, and combinations thereof.

Each of the first and second connecting members may be provided with at least one aperature, and secured to the first and second tiles, respectively, by fastening means through the at least one aperatures.

The number of connecting members in connection with a tile may vary. Although two may be sufficient for one tile, one, or more than two, may be used. It may be suitable to have, for example, one connector for each short side in a case of a tile having a plurality of short sides. It may be suitable with a system having a pair of connectors for each gap between adjacent tiles. Such as essentially four connectors per tile for an example with a surfrace comprised of squared tiles.
