Definitions

  • the present invention relates to a building panel adapted to be mounted at a ceiling or wall of a room so that a framework of the building panel has a room-facing side and a building-facing side, wherein the framework includes a peripheral frame formed by frame profile members, wherein a textile is extended over the room-facing side of the framework between the frame profile members, and wherein each edge of the textile is attached to a corresponding frame profile member by means of a spring-biased tensioning mechanism.
  • Such building panels can generally be used to cover interior surfaces in buildings, for instance in auditoriums, open-plan offices, etc.
  • buildings for instance in auditoriums, open-plan offices, etc.
  • panels for covering of boundaries of a room, such as the ceiling, the walls or partitions placed within the room.
  • Such panels can serve purely aesthetic purposes but can also be used to actively alter a room's characteristics, for instance relating to acoustic and thermal properties of the room.
  • WO 2005/073482 A2 discloses a system of building panels for suspended ceilings.
  • Each building panel includes a frame composed by profile members, and a room-facing side of the building panel is formed by a textile suspended between the profile members.
  • Different tensioning systems are disclosed whereby the textile may be stretched evenly over the opening of the frame and thereby form a smooth flat surface visible from the room.
  • the building panels disclosed are excellent when a smooth flat textile surface is desired, these building panels are generally not suitable if a curved textile surface is required.
  • building panels having a curved textile surface visible from the room may be required for different reasons, such as for aesthetic or practical purposes.
  • the required dimensions of such building panels may vary greatly.
  • the object of the present invention is to provide a building panel suitable for extending smoothly curved textile surfaces of any desired size.
  • the peripheral frame is composed by two opposed curved frame profile members and by two opposed straight frame profile members so that the extended textile forms a curved surface, each curved frame profile member is provided with a first spring-biased tensioning mechanism for tensioning the textile and each straight frame profile member is provided with a second spring-biased tensioning mechanism for tensioning the textile, and the first spring-biased tensioning mechanisms are of such a different mechanical construction than the second spring-biased tensioning mechanisms that each first spring-biased tensioning mechanism in the tensioned state of the textile provides a first tensioning force per unit edge length of the textile and each second spring-biased tensioning mechanism is adapted to provide a second maximum tensioning force per unit edge length of the textile, the first tensioning force per unit edge length of the textile being greater than the second maximum tensioning force per unit edge length of the textile.
  • the first spring-biased tensioning mechanisms may extend the textile between the two opposed curved frame profile members by means of a relatively greater force per unit edge length of the textile, thereby ensuring that the textile forms an intended curvature over the entire length of the peripheral frame between the curved frame profile members, and the second spring-biased tensioning mechanisms may by means of a relatively smaller force per unit edge length of the textile ensure that the textile is suitably stretched between the two opposed straight frame profile members without negatively influencing the intended curvature of the textile.
  • the second spring-biased tensioning mechanism may be of a simpler construction and may take up less space in the building panel than the first spring-biased tensioning mechanism.
  • the first tensioning force per unit edge length of the textile is at least two times greater, preferably at least five times greater and most preferred at least ten times greater than the second maximum tensioning force per unit edge length of the textile.
  • the two opposed curved frame profile members have identical curvatures.
  • the first tensioning force per unit edge length of the textile provided by said first spring-biased tensioning mechanism is adjustable, preferably steplessly.
  • each first spring-biased tensioning mechanism is arranged at least partly outside the corresponding curved frame profile member, and each second spring-biased tensioning mechanism is arranged inside a channel of the corresponding straight frame profile member.
  • the first spring-biased tensioning mechanism may by means of sturdy components suitably be configured to provide a relatively large tensioning force, whereas the second spring-biased tensioning mechanism may by means of smaller components suitably take up relatively little space in the building panel.
  • each first spring-biased tensioning mechanism includes at least one tension coil spring having a first end attached to a tension profile member forming part of the framework and being spaced from the curved frame profile member and a second end attached to the corresponding edge of the textile.
  • the first end of said tension coil spring is attached to an adjustment mechanism attached to the tension profile member.
  • the first end of said tension coil spring is attached to the eye of an eyebolt inserted through a hole in the tension profile member, and the bolt of the eyebolt is adjustably mounted in the hole of the tension profile member by means of a nut screwed onto the bolt.
  • the second end of said tension coil spring is attached, preferably by means of a hook member, to an elongated profile attached along the corresponding edge of the textile.
  • each curved frame profile member has a building-facing side and a room-facing side connected by means of a rounded edge about which the textile is bent, and the elongated profile is arranged in a channel in the building-facing side of the curved frame profile member and is preferably attached to the second end of said tension coil spring by means of a hook member extending through an opening in the curved frame profile member.
  • the edge of the textile may suitably be attached to the first spring-biased tensioning mechanism at the building-facing side of the curved frame profile member, and at the same time the first spring-biased tensioning mechanism may include a relatively large tension coil spring situated outside the curved frame profile member.
  • each straight frame profile member has a building-facing side and a room-facing side connected by means of a rounded edge about which the textile is bent
  • each second spring-biased tensioning mechanism includes a bracket arranged in a channel in the building-facing side of the straight frame profile member, and the bracket is spring-biased sideward in the track in order to tension the textile between the opposed rounded edges of the opposed straight frame profile members.
  • a suitable maximum tensioning force may be provided by the second spring-biased tensioning mechanism.
  • the distance between the two opposed curved frame profile members is at least 2/3 of, preferably greater than and most preferably at least 4/3 of the distance between the two opposed straight frame profile members.
  • each curved frame profile member is made from an extruded metal profile, preferably made of aluminium
  • each curved frame profile member is provided with a number of lateral slits spaced from each other in the longitudinal direction of the curved frame profile member, each lateral slit extends only partly through the extruded metal profile, and each curved frame profile member is strengthened by means of a flat, curved metal plate attached to the extruded metal profile along its length.
  • the flat, curved metal plate may easily be cut to the desired curvature, for instance by means of a laser cutter, and may compensate for the flexibility of the extruded profile member provided by the lateral slits. In this way, conveniently, the same type of extruded profile member may be employed for producing both the straight frame profile members and the curved frame profile members.
  • the present invention further relates to a method of manufacturing a building panel adapted to be mounted at a ceiling or wall of a room so that a framework of the building panel has a room-facing side and a building-facing side, the framework including a peripheral frame formed by frame profile members, whereby a textile is extended over the room-facing side of the framework between the frame profile members, and whereby each edge of the textile is attached to a corresponding frame profile member by means of a spring-biased tensioning mechanism.
  • the method is characterised in that the peripheral frame is composed by two opposed curved frame profile members and by two opposed straight frame profile members in order for the extended textile to form a curved surface, in that, firstly, the textile is tensioned to a first tensioning force per unit edge length of the textile in relation to each curved frame profile member by means of a first spring-biased tensioning mechanism and, secondly, the textile is tensioned to a second tensioning force per unit edge length of the textile in relation to each straight frame profile member by means of a second spring-biased tensioning mechanism, the first tensioning force per unit edge length of the textile being greater than the second tensioning force per unit edge length of the textile.
  • the first spring-biased tensioning mechanisms may extend the textile between the two opposed curved frame profile members by means of a relatively greater force per unit edge length of the textile, thereby ensuring that the textile forms an intended curvature over the entire length of the peripheral frame between the curved frame profile members, and the second spring-biased tensioning mechanisms may by means of a relatively smaller force per unit edge length of the textile ensure that the textile is suitably stretched between the two opposed straight frame profile members without negatively influencing the intended curvature of the textile.
  • the textile By firstly tensioning the textile by means of the relatively greater force by means of the first spring-biased tensioning mechanisms, it may be ensured that the textile forms said intended curvature over the entire length of the peripheral frame between the curved frame profile members before the textile is attached to the straight frame profile members. Thereby, the length of the textile between the opposed straight frame profile members may be adapted accordingly before attachment by means of the second spring-biased tensioning mechanisms. Therefore, the second spring-biased tensioning mechanisms may not need to be adapted to take up large variations in the length of the textile and may therefore be of a relatively simple construction as compared to the first spring-biased tensioning mechanisms.
  • the second spring-biased tensioning mechanism may be of a relatively simpler construction and may take up less space in the building panel than the first spring-biased tensioning mechanism.
  • the first tensioning force per unit edge length of the textile is at least two times greater, preferably at least five times greater and most preferred at least ten times greater than the second maximum tensioning force per unit edge length of the textile.
  • the first tensioning force per unit edge length of the textile provided by the first spring-biased tensioning mechanism is adjusted, preferably steplessly, by means of the first spring-biased tensioning mechanism.
  • the distance between the two opposed curved frame profile members is at least 2/3 of, preferably greater than and most preferably at least 4/3 of the distance between the two opposed straight frame profile members.

  • the first spring-biased tensioning mechanisms 6 are of a different mechanical construction than the second spring-biased tensioning mechanisms 7, whereby each first spring-biased tensioning mechanism 6 is arranged to provide, in the tensioned state of the textile 9, a first tensioning force per unit edge length of the textile 9, and each second spring-biased tensioning mechanism 7 is adapted to provide a second maximum tensioning force per unit edge length of the textile 9, whereby the first tensioning force per unit edge length of the textile is greater than the second maximum tensioning force per unit edge length of the textile.
  • the textile is extended by a relatively greater force (per unit edge length of the textile) in the direction extending between the two opposed curved frame profile members 13 than in the direction extending between the two opposed straight frame profile member 14.
  • the tensioning force per unit edge length of the textile 9 is understood as the total tensioning force applied to the textile over a certain edge 18 of the textile 9 divided by the length of that edge of the textile.
  • the first tensioning force per unit edge length of the textile is at least two times greater, preferably at least five times greater and most preferred at least ten times greater than the second maximum tensioning force per unit edge length of the textile.
  • the two opposed curved frame profile members 13 have identical curvatures. It is further preferred, as it will be explained in further detail below, that the first tensioning force per unit edge length of the textile provided by said first spring-biased tensioning mechanism 6 is adjustable, preferably steplessly.
  • each first spring-biased tensioning mechanism 6 is arranged at least partly outside the corresponding curved frame profile member 13, and each second spring-biased tensioning mechanism 7 is arranged inside a channel 21 of the corresponding straight frame profile member 14.
  • each first spring-biased tensioning mechanism 6 includes a number of tension coil springs 12 having a first end 23 attached to a tension profile member 26 forming part of the framework 2 and being spaced from the curved frame profile member 13 and a second end 24 attached to the corresponding edge 18 of the textile 9.

  • the adjustment mechanism 27 may be of any other suitable type known to the skilled person.
  • the second end 24 of said tension coil spring 12 is by means of a hook member 34 attached to an elongated profile 35 attached along the corresponding edge 18 of the textile 9.

  • each edge 18 of the textile 9 may be provided with a number of elongated profiles 35 arranged in continuation of each other and possibly spaced.
  • the thickened area 50 along the edge 18 of the textile 9 is formed by means of a hem 54 with a string 55 or rod inside.
  • the elongated profile 35 is particularly well illustrated in Figs. 12 and 13 , and the elongated profile 35 and the thickened area 50 are illustrated in cross-section in Fig. 12 .
  • each curved frame profile member 13 has a building-facing side 17 and a room-facing side 16 connected by means of a rounded edge 15 about which the textile 9 is bent.

  • Each edge 18 of the textile 9 is provided with a bracket 20 arranged in a channel 21 in the building-facing side 17 of the corresponding straight frame profile member 14, and the bracket 20 is spring-biased sideward in the channel 21 by means of the least one spring member 19 in order to tension the textile 9 between the opposed rounded outer edges 15 of the respective straight frame profile members 14.
  • the spring member 19 has the form of an elongated flexible hoop. As illustrated in Figs. 14 to 16 , the edge 18 of the textile 9 is fixed in a serrated track 30 extending longitudinally in the bracket 20 in that a retaining member 22 in the form of a spring is pressed into the serrated track 30, thereby pinching the textile edge 18 against the serrated walls of the serrated track 30.
  • the distance between the two opposed curved frame profile members 13 is at least 2/3 of, preferably greater than and most preferably at least 4/3 of the distance between the two opposed straight frame profile members 14.
  • the above-described arrangement of the first and second spring-biased tensioning mechanisms 6, 7 for tensioning the textile 9 is specifically advantageous for panels having the just mentioned distance between the two opposed curved frame profile members 13, because with such dimensions, by means of already known tensioning systems providing equal tensioning force per unit edge length of the textile in both directions of the textile, it would be very difficult ensuring that the textile forms an intended curvature over the entire length of the peripheral frame between curved frame profile members. Typically, with already known tensioning systems, this would result in the textile flattening out in a central part of the panel.

  • the framework 2 as partly illustrated in Fig. 8 is assembled from the peripheral frame 5 formed by the four frame profile members 13, 14 described above, as well as two tension profile members 26 of which one is seen in the figure, a number of curved framework profile members 42, and a number of straight framework profile members 43.
