Definitions

  • the present invention relates to a ceiling comprising a first set of a plurality of tiles and a second set of a plurality of tiles.
  • the invention also relates to a method of arranging such a ceiling.
  • ceilings are normally used not only to provide an acoustical environment but also to conceal cable arrangement, ventilation equipment, lighting installations and other features.
  • One common type of ceilings is made up by a number of tiles being arranged in profiles, which profiles are mounted in hanging suspensions. By the tiles normally being quadrangular a continuous grid pattern is formed. In order to provide an aesthetical appearance, a symmetry should be strived for. However, since the tiles are provided in a limited number of sizes, this means that the tiles along the walls normally have to be cut to fit. In fact, cutting is in most cases necessary no matter if symmetry is a requirement or not.
  • the easiest way to form the symmetry is to make a drawing according to scale and mark a reference point.
  • a reference point could be a centreline or a point of intersection depending on whether the area is a corridor or a room.
  • the continuous grid pattern is adapted to the reference point whereby the perimeter becomes symmetrical, i.e. the width of the tiles along two opposing walls becomes the same.
  • the tiles along a wall are generally known as a perimeter or a frieze.
  • Tiles are provided in a number of dimensions, normally quadrangular.
  • the tiles are provided in a great variety of edge designs, such as geometrical profiles, surface treatments, brackets and trimmings depending on the intended mounting, joint type and visual appearance. Accordingly, two opposing edges may not be identical.
  • the objects of the present invention are to provide a ceiling structure allowing a substantial reduction of the cutting required, a minimum of waste material and a minimum of required restoration of cut edges in order of reducing the total cost of mounting a ceiling.
  • a further object is to improve the acoustic properties of the ceiling.
  • the present invention refers to a ceiling comprising a first set of a plurality of tiles and a second set of a plurality of tiles.
  • the ceiling is characterized in that the tiles in said first set are consecutively arranged, forming along at least one wall in a room a row of tiles having the width of a single tile, said first set forming a perimeter being arranged in a plane different from a plane of the second set, and said perimeter having a free edge facing the room overlapping a free edge of the second set of tiles facing the wall.
  • the cutting required may be kept to a minimum. More precisely, by the first set of tiles having a width of a single tile there is no need of cutting each tile adjacent a wall in said first set. Instead the cutting may be limited to adjust the length of one tile per row. In practice this means that in a corridor having two perimeters (two rows), two perimeter tiles must be cut. Correspondingly, in a quadrangular room four tiles must be cut, i.e. one tile per wall (four rows).
  • walls are more or less irregular or uneven. Such irregularities form aesthetical defects.
  • One known measure is to arrange a gap between the wall and the edge of the tiles. Normally, with prior art technology the cutting at each panel means that the cut edge must be provided with a trimming if the gap makes the cut edge visible. Since the present invention to a very large extent reduces cutting, restoration of the tiles can be reduced.
  • the cutting of the tiles of the second set of tiles may in many cases be avoided, simply by choosing the size of the individual tiles in the second set so that an area is formed that is adapted to the area delimited by the inner circumference formed by the free edges of the first set of tiles.
  • the arrangement allows for large tolerances, i.e. the area formed by the tiles of the second set may be considerably larger than the area delimited by the inner circumference formed by the free edges of the first set of tiles.
  • the overlapping area comprises a superfluous amount of tile material is of no problem when it comes to material savings since that material in prior art arrangements would have been cut off forming waste material. Said cutting would not only form waste material, but is also labour intensive and time consuming and thereby expensive in terms of the total cost for a construction site. Also, the superfluous material forms a concealing sector which is used to conceal, for example, lighting and ventilation arrangements..
  • cut edges may simply be concealed by arranging the second set of tiles above the first set of tiles, or by providing said cut edges with a trimming in the case of the second set of tiles are arranged below the first set.
  • having an overlap area is advantageous for improving the room acoustic properties of the ceiling, especially in the low frequency range.
  • the irregularity of the ceiling in the overlap area in combination with the presence of two layers of tiles and the gap formed between the first and second set of tiles improves the acoustic properties of the ceiling.
  • Said first set of tiles may form a perimeter surrounding the second set of tiles. This arrangement refers to a perimeter wherein the rows form a closed loop.
  • the free edges of the lowest set of tiles may be provided with a trimming.
  • Trimmings may be used in order of restoring cut edges or in order of providing a strictly aesthetical impression. Restoration of cut edges are under some circumstances required in order to avoid dust formation. Trimmings may also be used in order to reflect lights or guiding air in case lighting means or ventilation means are arranged and concealed in the area between the two sets of tiles.
  • the term trimming is not only to be restricted to profiles, ledges or the like but should also include any coating or sealing.
  • Said second set may be arranged in a horizontal plane.
  • the first tile in each row forming the first set of tiles may be a tile having a cut edge, which cut edge is facing a wall in a corner.
  • the reduced amount of cutting results in enormous time and cost savings, not only due to the reduced cutting but also to the reduced amount of work involved when it comes to restoring the cut edges in order of fulfilling different requirements set on the edges.
  • the first and second sets of tiles may be arranged with a vertical gap between the two planes.
  • the vertical gap may be used in order to provide lighting to the room, which lighting may be arranged above at least one of the first and second sets of tiles.
  • the vertical gap may also be used in order to provide inlet and/or outlet air supply for ventilation of the room or strictly as an aesthetical arrangement.
  • the first set of tiles may be arranged in a plane angled to the plane formed by the second set of tiles. Having angled tiles in the perimeter improves the acoustic properties of the ceiling.
  • the angled orientation creates a void of varying size and forms an irregularity of the ceiling, which is advantageous for improving the sound-absorption properties of the ceiling, especially in the low frequency range.
  • the angled orientation of the first set of tiles improves the luminous efficiency of lighting arranged in the void between the first set and the second set of tiles.
  • the angled orientation may also be used for controlling the direction of the light.
  • the invention refers to a method of arranging a ceiling comprising a first set of a plurality of iles and a second set of a plurality of tiles, the method comprising the steps of mounting a first set of tiles forming a perimeter along at least one wall in a room, said perimeter having the form of one row of consecutively arranged tiles, the row having the width of one single tile, and mounting a second set of tiles in the area delimited by the free edges of the first set of tiles, the second set being arranged in a plane different from a plane of the first set, and said free edges of the first set of tiles facing the room overlapping the free edges of the second set of tiles facing the wall.
  • the method may further comprise arranging the first and second set of tiles with a vertical gap between the two planes.
  • the method may further comprise the step of providing the free edges of the lowest set of tiles with a trimming.
  • the method may further comprise arranging the first tile in each row with its cut edge facing a wall in a corner.
  • the tiles in the first set may be mounted following the steps of:
  • the tiles in the first set may be mounted by starting at a first wall by arranging a number of uncut tiles one after the other in a row along a second wall until a gap is formed at a third wall, which gap is smaller than the length of an uncut tile, and arranging a cut tile in said gap with its cut edge facing the third wall.
  • the tiles in the first set may be mounted by starting at a first wall by arranging a number of uncut tiles one after the other in a row along a second wall, said row forming a uniform gap between the first wall and the first tile and a third wall and the last tile respectively, which gaps are smaller than the length of an uncut tile, and arranging a cut tile in each of said gaps, said cut tiles being arranged with their cut edges facing the corners formed between the first and the second wall and the second and the third wall respectively.
  • the method comprises generally the same features as the inventive ceiling and thereby presents the same results and advantages as those previously discussed.
  • Figure 1 discloses a typical ceiling according to prior art.
  • Figures 2a and 2b disclose a ceiling according to one embodiment of the present invention.
  • Figure 3a and 3b disclose two embodiments of the ceiling suitable to be used in a corridor.
  • the room 102 being quadrangular has four walls 101 limiting an area. Further, the room 102 has a ceiling 100, the ceiling being viewed from below.
  • the ceiling 100 comprises a number of tiles 103 being arranged side by side in rails 104 forming a continuous grid pattern starting from a centrally arranged reference point P.
  • the reference point P is constituted by the geometrical centre point of the ceiling.
  • the reference point P may by way of example be positioned in a tile 103 such as disclosed or in a point of intersection between four tiles in the middle of the ceiling. This means that in most cases all tiles adjacent a wall have to be cut in order of fitting the available area.
  • the row of tiles closest to the walls are generally referred to as a perimeter 105 or a frieze.
  • Cutting a tile 103 means that the cut off portion generally becomes waste material for a number of reasons. In most cases, the cut off portion is simply too small to be re-used in the perimeter 105. Also, in most cases, the opposing edges of a tile are not symmetrical, whereby it is not possible to turn the cut off tile portion 180 degrees to fit an adjacent tile. Also, when cutting a tile, the cut must generally be restored, either in the form of a sealing or a trimming. Restoration is required not only for aesthetical reasons but also for a number of technical reasons, such as avoiding formation of dust. Restoration in the form of a trimming may also be required to form a connecting means suitable to fit adjacent tiles or wall fittings.
  • the ceiling 1 comprises two sets 2, 3 of tiles 4a-4c.
  • the first set 2 of tiles is arranged one tile 4a, 4b after the other in a continuous row 6 along the walls 101 forming a perimeter 7.
  • the perimeter 7 is divided into four rows 61-64, i.e. one row along each wall 101.
  • the four rows 61-64 are together forming a closed loop.
  • the perimeter 7 has a width W corresponding to the width V of the individual tiles 4a, 4b that are making up the perimeter 7. Further, only one tile per row is cut, i.e. tiles 4b.
  • a number of uncut tiles 4a are consecutively arranged one after the other starting on a distance Y from the first wall 1011.
  • the distance Y corresponds to the width V of a tile 4a, 4b.
  • the uncut tiles 4a are arranged along the second wall 1012 in a first row 61.
  • a gap 8 is formed between the last tile in the first row 61 and the third wall 1013 which gap is smaller than the length L of an uncut tile 4a
  • the following tile 4b is cut to a length X corresponding to said gap and arranged to fill the gap.
  • the cut tile 4b is arranged in the corner 9 between the second wall 1012 and the third wall 1013 with its cut edge 10 facing the third wall 1013.
  • This pattern is then repeated, following that in the subsequent, second row 62, the first tile is an uncut tile 4a whereas the last tile in said row is a cut tile 4b having its cut edge 10 arranged in the corner 9 between the third wall 1013 and the fourth wall 1014 with its cut edge 10 facing the fourth wall 1014.
  • This pattern is repeated along all four walls 1011-1014 until a perimeter 7 in the form of a closed loop is formed. In the resulting perimeter 7 only four tiles 4b have to be cut.
  • the second set of tiles 3 forms a continuous grid pattern of tiles 4c having an area B.
  • the area B is larger than the area A.
  • the two sets 2, 3 of tiles are arranged extending in different planes. By area B being larger than area A, an overlap C is formed between the two sets 2, 3 of tiles.
  • the second set 3 of tiles is arranged below the first set 2 of tiles.
  • the second set 3 of tiles may be arranged above the first set 2 of tiles.
  • the ceiling 1 allows for large tolerances, i.e area B may be considerably larger than area A since such overlap is not visible when the ceiling is looked at from below.
  • area B may be considerably larger than area A since such overlap is not visible when the ceiling is looked at from below.
  • the overlap improves the acoustic properties of the ceiling.
  • the fact that the overlapping area comprises a superfluous amount of tile material is of no problem when it comes to a question of material savings since such cut off material would form waste material of no use to the ceiling. It is to be understood that the amount of overlapping may be adjusted by choosing the size of the tiles in the first and second sets of tiles.
  • the first set 2 of tiles i.e. the perimeter 7 is mounted to the wall 101 by using fixing means and rails 12 generally known in the art.
  • the rails 12 are fixed to the walls and the tiles 4a, 4b are supported by the rails 12 along their edges 13.
  • the opposite free edges 11 of the tiles 4a are suspended from the inner ceiling 15 by well known fixing means 14.
  • the second set 3 of tiles are suspended in the inner ceiling 15 by using fixing means 14 well known in the art.
  • fixing means 14 such as wires may be used.
  • a space D is formed to accommodate and conceal such features.
  • Such gap may be used to form a light scattering or to form an air diffusion.
  • Lighting or air supply means may also be arranged in lead-troughs in the tiles.
  • Trimmings 17 may be used to enhance the effect of light scattering or air diffusion.
  • the corridor may either be provided with a ceiling wherein the tiles in the first set 2 form a closed loop as disclosed above or with a ceiling wherein the tiles in the first set 2 are arranged according to a principle to be disclosed below.
  • the perimeter 7 is divided into two separate rows 61, 62, one row along each wall of the longer walls 1011, 1013.
  • a number of uncut tiles 4a are arranged consecutively in a row along the walls 1011, 1013 starting at one of the short walls 1012 until a gap 8 results at the opposing short wall 1014, which gap is smaller than the length of an uncut tile 4a.
  • This gap 8 is filled by a cut tile 4b.
  • the cut tile 4b is arranged in the corner 9 with its cut edge 10 facing the short wall 1014. The same procedure is repeated along the opposing wall. For aesthetical reasons the cut tiles 4b could be arranged in the same end of the corridor.
  • the perimeter 7 has a width W corresponding to the width of a single tile V.
  • the first and the last tiles in each row 61, 62 may be cut tiles 4b in accordance with the principles discussed above with reference to Figure 3a .
  • four tiles in the first set 2 of tiles must be cut. This might be aesthetically favourable depending on the length of the corridor.
  • the area A' between the two rows 61, 62 i.e. the area delimited by the free edges 11 of the rows 61, 62 facing the corridor and the short walls 1012, 1014 of the corridor, is filled with a second set 3 of tiles that is arranged overlapping the first set of tiles 2.
  • the second set 3 of tiles have an area B' being larger than area A'.
  • such second set of tiles 4c may either be a single row of juxtaposed tiles 4c as disclosed or a number of tiles arranged in a grid pattern along the corridor. According to such principle the only tiles that have to be cut in the second set 3 of tiles are those at the ends of the corridor. Those tiles may be provided with a trimming or similar in a conventional manner.
  • the panels are made of compressed fiber material, preferably mineral fibers, such as glass wool or stone wool, or gypsum.
  • all tiles have had the same properties. It is though to be understood that the tiles in the first and second sets may have different properties such as acoustical properties or visual appearance. Also, the tiles either individually or in the two sets may have different geometries, sizes, colour and/or visual appearance etc.
