Description

DESCRIPTION

Building panel adapted to be mounted on a ceiling or wall of a room and method of manufacturing such building panel

The present invention relates to a building panel adapted to be mounted on a ceiling or wall of a room such that a frame of the building panel has a side facing the room and a side facing the building, wherein the frame includes a peripheral frame formed by frame profile elements, in which a textile material extends on the room-facing side of the frame between the frame profile elements, and in which each edge of the textile material is attached to a corresponding frame profile element by means of a spring biased tensioning mechanism.

Such building panels can generally be used to cover interior surfaces in buildings, for example, in auditoriums, open-plan offices, etc. In fields such as architecture and interior design, there is often a need for panels to cover the boundaries of a room, such as the ceiling, walls, or partitions placed within the room. Such panels can serve purely aesthetic purposes, but can also be used to actively alter the characteristics of a room, for example in relation to the acoustic and thermal properties of the room.

WO 2005/073482 A2 discloses a building panel system for suspended ceilings. Each building panel includes a frame made up of profile elements, and a room-facing side of the building panel is formed by a textile material suspended between the profile elements. Different tensioning systems are disclosed whereby the textile material can be uniformly stretched over the opening of the frame and thus form a flat smooth surface visible from the room. However, while the disclosed building panels are excellent where a flat, smooth fabric surface is desired, these building panels are generally not suitable where a curved fabric surface is required.

In the fields of architecture and interior design, 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 can vary greatly.

The object of the present invention is to provide a building panel suitable for laying out slightly curved textile surfaces of any desired size.

In view of this object, the peripheral frame is composed of two opposite curved frame profile elements and two opposite straight frame profile elements so that the stretched textile material forms a curved surface, each curved frame profile element is provided with a first spring-biased tensioning mechanism for tensioning the textile material and each straight frame profile member is provided with a second spring-biased tensioning mechanism for tensioning the textile material, 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 fabric-tensioned state provides a first tensioning force per unit edge length of the fabric and each second mechanism spring-biased tensioning mechanism is adapted to provide a second te maximum tension per unit edge length of the textile material, the first tension force per unit edge length of the textile material being greater than the second maximum tension force per unit edge length of the textile material.

In this way, by ensuring said difference between the first and second tensioning forces per unit edge length of the fabric, the first spring-biased tensioning mechanisms can stretch the fabric between the two opposed curved frame profile members by by means of a relatively greater force per unit edge length of the fabric, thereby ensuring that the fabric forms a predicted curvature over the full length of the peripheral frame between the curved frame profile members, and the second tensioning mechanisms biased by springs can, by means of a relatively minor force per unit edge length of the fabric, ensure that the fabric is properly stretched between the two opposite straight frame profile elements without negatively influencing the intended curvature of the fabric . Furthermore, as a consequence of said difference between the first and second tensioning forces per unit edge length of the fabric material, advantageously, the second spring-biased tensioning mechanism can have a simpler construction and can take up less space on the panel. construction than the first spring-biased tensioning mechanism.

In one embodiment, the first tensile force per unit edge length of the fabric is at least two times greater, preferably at least five times greater, and most preferably at least ten times greater than the second maximum tensile force per unit edge length. edge length of the textile material. In this way, it can be further ensured that the textile material forms a planned curvature over the entire length of the peripheral frame between the curved frame profile elements.

In a particularly structurally advantageous embodiment, the two opposite curved frame profile elements have identical curvatures.

In one embodiment, in the attached state of a fabric edge to a corresponding curved frame profile element by means of the first spring-biased tensioning mechanism, the first tensioning force per unit length of fabric edge provided by said first spring-biased tensioning mechanism is preferably continuously adjustable. In this way, by adjusting the first tensioning force as a function of the actual curvature of the curved frame profile elements, it can be further ensured that the textile material forms a planned curvature over the entire length of the peripheral frame between the elements. of curved frame profiles.

In one embodiment, each first spring biased tensioning mechanism is disposed at least partially outside the corresponding curved frame profile member, and each second spring biased tensioning mechanism is disposed within a channel of the corresponding straight frame profile member. . Thus, the first spring-biased tensioning mechanism can, by means of robust components, be suitably configured to provide a relatively large tensioning force, while the second spring-biased tensioning mechanism can, by means of smaller components, suitably take up relatively little space on the building panel.

In a particularly structurally advantageous embodiment, each first spring-biased tensioning mechanism includes at least one helical tension spring having a first end attached to a tension profile element forming part of the frame and spaced apart from the tensioning element. curved frame profile and a second end attached to the corresponding edge of the textile material.

In a structurally particularly advantageous embodiment, the first end of said helical tension spring is attached to an adjustment mechanism attached to the tension profile element. In this way, by adjusting the first tensioning force as a function of the actual curvature of the curved frame profile elements, it can be further ensured that the textile material forms a planned curvature over the entire length of the peripheral frame between the elements. of curved frame profiles.

In a particularly structurally advantageous embodiment, 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 eyebolt bolt is adjustablely mounted on the hole of the tension profile element by means of a nut screwed onto the bolt.

In a particularly structurally advantageous embodiment, the second end of said helical tension spring is attached, preferably by means of a hook element, to an elongated profile attached along the corresponding edge of the textile material.

In one embodiment, each curved frame profile element has a building-facing side and a room-facing side connected by a rounded edge around which the fabric is folded, and the elongated profile is arranged in a channel. on the building-facing side of the curved frame profile element and is preferably attached to the second end of said helical tension spring by means of a hook element extending through an opening in the curved frame profile element . In this way, the edge of the textile material can be suitably attached to the first spring-biased tensioning mechanism on 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 located outside the curved frame profile member.

In one embodiment, each straight frame profile element has a building-facing side and a room-facing side connected by a rounded edge around which the fabric is folded, each second spring-biased tensioning mechanism includes a clamp disposed in a channel on the building-facing side of the straight frame profile element, and the clamp is spring biased sideways on the track in order to tension the fabric between the opposing rounded edges of the elements opposite straight frame profiles. In this way, the second spring biased tensioning mechanism can provide an adequate maximum tensioning force.

In one embodiment, the distance between the two opposite curved frame profile elements is at least 2/3 of, preferably greater than, and most preferably at least 4/3 of the distance between the two opposite straight frame profile elements. . The above-described arrangement of the first and second spring-biased tensioning mechanisms for tensioning the fabric is specifically advantageous for panels having the just-mentioned distance between the two opposing curved frame profile elements, because with such dimensions, for By means of known tensioning systems which provide an equal tensioning force per unit edge length of the fabric in both directions of the fabric, it would be very difficult to ensure that the fabric forms a predicted curvature over the entire length of the peripheral frame between the curved frame profile elements. Typically, with known tensioning systems, this would result in the fabric flattening out in a central part of the panel.

In one embodiment, each curved frame profile element is made of an extruded metal profile, preferably made of aluminium, each curved frame profile element is provided with a number of lateral grooves spaced apart from each other in the longitudinal direction of the frame element. curved frame profile, each side slot extends only partially through the extruded metal profile, and each curved frame profile element is reinforced by means of a flat, curved metal plate attached to the extruded metal profile along its length. In this way, a mass-produced extruded profile member can be easily formed to give any desired curvature of an actual building panel frame. The flat, curved metal plate can be easily cut to give the desired curvature, for example by means of a laser cutter, and can compensate for the flexibility of the extruded profile element provided by the lateral grooves. Thus, conveniently, the same type of extruded profile member can be used to produce 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 on a ceiling or wall of a room such that a frame of the building panel has one side facing the room and one side facing the building. , the frame including a peripheral frame formed by frame profile elements, whereby a textile material is extended on the room-facing side of the frame between the frame profile elements, and whereby each edge of the textile material is attaches to a corresponding frame profile member by means of a spring-biased tensioning mechanism.

The method is characterized in that the peripheral frame is composed of two opposite curved frame profile elements and two opposite straight frame profile elements so that the stretched textile material forms a curved surface, because, first of all, the textile material is tensioned to a first tensioning force per unit edge length of the textile material relative to each curved frame profile element by means of a first spring-biased tensioning mechanism, and secondly, the textile material is tensioned to a second tensioning force per unit edge length of the fabric relative to each straight frame profile element by means of a second spring-biased tensioning mechanism, the first tensioning force per unit edge length being of the textile material greater than the second tensile force per unit edge length of the textile material.

In this way, by ensuring said difference between the first and second tensioning forces per unit edge length of the fabric, the first spring-biased tensioning mechanisms can stretch the fabric between the two opposed curved frame profile members by by means of a relatively greater force per unit edge length of the fabric, thereby ensuring that the fabric forms a predicted curvature over the full length of the peripheral frame between the curved frame profile members, and the second tensioning mechanisms biased by springs can, by means of a relatively minor force per unit edge length of the fabric, ensure that the fabric is properly stretched between the two opposite straight frame profile elements without negatively influencing the intended curvature of the fabric . By first tensioning the textile material by means of the relatively larger force by means of the first spring-biased tensioning mechanisms, it can be ensured that the textile material forms said intended curvature over the entire length of the peripheral frame between the profile elements. curved frames before the textile material is attached to the straight frame profile elements. In this way, the length of the textile material between the opposite straight frame profile elements can be adapted accordingly before joining by means of the second spring-biased tensioning mechanisms. Thus, the second spring-biased tensioning mechanisms may not need to be adapted to accommodate large variations in the length of the fabric and thus may be relatively simple in construction compared to the first spring-biased tensioning mechanisms. Furthermore, also as a consequence of said difference between the first and second tensioning forces per unit edge length of the textile material, advantageously, the second spring-biased tensioning mechanism can have a relatively simpler construction and can occupy less space in the construction panel than the first spring biased tensioning mechanism.

In one embodiment, the first tensile force per unit edge length of the fabric is at least two times greater, preferably at least five times greater, and most preferably at least ten times greater than the second maximum tensile force per unit edge length. edge length of the textile material. Thereby, the characteristics mentioned above can be obtained.

In one embodiment, prior to tensioning the fabric relative to each straight frame profile element by the second spring-biased tensioning mechanism, the first tensioning force per unit edge length of the fabric provided by the first mechanism The spring biased tensioning mechanism is preferably continuously adjusted by the first spring biased tensioning mechanism. Thereby, the characteristics mentioned above can be obtained.

In one embodiment, the distance between the two opposite curved frame profile elements is at least 2/3 of, preferably greater than, and most preferably at least 4/3 of the distance between the two opposite straight frame profile members. Thereby, the characteristics mentioned above can be obtained. The invention will now be explained in more detail below by means of exemplary embodiments with reference to the highly schematic drawing, in which

Figure 9 illustrates part of an embodiment of a building panel 1 according to the present invention, adapted to be mounted on a ceiling or wall of a room such that a building panel frame 2 has a side 3 facing the room and a side 4 facing the building. The frame 2 includes a peripheral frame 5 formed by frame profile elements 13, 14, only two of which are visible in the figure. A textile material 9 extends on the room-facing side 3 of the frame 2 between the frame profile elements 13, 14, and each edge 18 of the textile material 9 is attached to a corresponding frame profile element by means of a spring-biased tensioning mechanism 6, 7. The textile material 9 has a first surface 10 oriented towards the frame 2 and a second surface 11 generally visible from said room, as seen in figure 11.

Peripheral frame 5 is made up of two opposite curved frame profile elements 13 of which only one is illustrated at the bottom of Figure 9 and two opposite straight frame profile elements 14 of which only one is illustrated at the right of the figure. Therefore, it is understood that the part of the building panel 1 illustrated in Figure 9 forms a lower, right part (as seen in the figure) of the entire building panel 1. Thus, as illustrated, the extended textile material 9 forms a curved surface, which in the illustrated embodiment is concave when viewed from the room-facing side 3 of the frame 2. In other embodiments, the extended textile material 9 may form a curved surface that is convex. Depending on the shape of the curved frame profile elements 13, the extended textile material 9 may form a curved surface that is partially cylindrical, such as a partially circular cylindrical surface.

Each curved frame profile element 13 is provided with a first spring-biased tensioning mechanism 6 for tensioning the textile material 9 as illustrated in more detail in Figures 9 to 13. Furthermore, each straight frame profile element 14 is provided with a second spring-biased tensioning mechanism 7 for tensioning the textile material 9 as illustrated in more detail in Figures 14 to 16. As can be seen, the first spring-biased tensioning mechanisms 6 have a mechanical construction different from that of 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 material 9, a first tensioning force per unit length of edge of the textile material 9, and each second spring-biased tensioning mechanism 7 is adapted to provide a second maximum tensioning force per unit length of edge of the textile material 9, whereby the first tensile force per unit edge length of the material fabric is greater than the second maximum tensile force per unit edge length of the fabric. In this way, it is ensured that the textile material is stretched by a relatively greater force (per unit edge length of the textile material) in the direction that extends between the two opposite curved frame profile elements 13 than in the direction that it extends between the two opposite curved frame profile elements 14. It is noted that the tensioning force per unit edge length of the textile material 9 is understood as the total tensioning force applied to the textile material on a given edge 18 of the textile material 9 divided by the length of that edge of the textile material.

It is preferable that the first tensile force per unit edge length of the textile material is at least two times higher, preferably at least five times higher and most preferred at least ten times higher than the second maximum tensile force per unit length. edge of the textile material. As in the illustrated embodiment, it is preferable that the two opposing curved frame profile members 13 have identical curvatures. It is further preferable, as will be explained in more detail below, that the first tensioning force per unit edge length of the fabric provided by said first spring-biased tensioning mechanism 6 is preferably continuously adjustable.

Comparing, on the one hand, figures 9 and 11 and, on the other hand, figures 14 and 16, it can be seen that each first spring-biased tensioning mechanism 6 is arranged at least partially outside the corresponding curved frame profile element 13 , and each second spring-biased tensioning mechanism 7 is disposed within a channel 21 of the corresponding straight frame profile member 14.

As illustrated in Figures 9 to 11, each first spring-biased tensioning mechanism 6 includes a number of helical tension springs 12 having a first end 23 attached to a tension profile member 26 forming part of frame 2 and it is spaced from the curved frame profile element 13 and a second end 24 attached to the corresponding edge 18 of the textile material 9 .

The first end 23 of said helical tension spring 12 is attached to an adjustment mechanism 27 attached to the tension profile element 26 in the following way: the first end 23 of said helical tension spring 12 is attached to the eye 29 of a eyebolt 28 inserted through a hole 31 in the tension profile element 26, and the bolt 32 of the eyebolt 28 is adjustablely mounted in the hole 31 of the tension profile element 26 by means of a nut 33 screwed into the bolt 32. Of course, the adjustment mechanism 27 can be of any other suitable type known to those skilled in the art. The second end 24 of said helical tension spring 12 is attached by means of a hook element 34 to an elongated profile 35 attached along the corresponding edge 18 of the textile material 9 . The elongated profile 35 grips on a thickened zone 50 along the edge 18 of the textile material 9 . The elongated profile 35 has a tubular cross section 51 with a longitudinally extending slot 52 through which the textile material 9 extends, and the elongated profile 35 is attached to the second hook 48 of the hook element 34 because the second hook 48 is inserted into a hole 53 in the flange 49 of the elongated profile 35. Each elongated profile 35 can be provided with several holes 53, each one being connected with an independently tensioned helical spring 12. Furthermore, each edge 18 of the textile material 9 can be provided with several elongated profiles 35 arranged one after the other and possibly separated. The thickened area 50 along the edge 18 of the textile material 9 is formed by means of a hem 54 with a cord 55 or rod inside. The elongated profile 35 is particularly well illustrated in Figures 12 and 13, and the elongated profile 35 and thickened area 50 are illustrated in cross-section in Figure 12.

As best illustrated in Figure 11, each curved frame profile element 13 has a side 17 facing the building and a side 16 facing the room connected by a rounded edge 15 around which the material 9 is folded. textile. The elongated profile 35 is arranged in a channel 21 on the building-facing side 17 of the curved frame profile element 13 and is attached to the second end 24 of said helical tension spring 12 by means of the hook element 34 extending through an opening 36 in the curved frame profile element 13; see also figure 2.

As illustrated in Figures 14 to 16, each straight frame profile element 14 has a rounded outer edge 15 connecting a room-facing side 16 of the straight frame profile element 14 with a building-facing side 17 of the straight frame profile element 14. The textile material 9 is folded around the rounded outer edges 15 of the straight frame profile elements 14, and one edge 18 of the textile material 9 is elastically fixed by means of at least one spring element 19 to the side 17 facing the building of the straight frame profile elements 14. Each edge 18 of the textile material 9 is provided with a clamp 20 disposed in a channel 21 on the building-facing side 17 of the corresponding straight frame profile element 14, and the clamp 20 is spring biased laterally in the channel 21 by by means of at least one spring element 19 in order to tension the textile material 9 between the opposite rounded outer edges 15 of the respective straight frame profile elements 14 . The spring element 19 is in the form of an elongated flexible ring. As illustrated in figures 14 to 16, the edge 18 of the textile material 9 is fixed in a longitudinally extending toothed track 30 in the clamp 20 in which a spring-shaped retaining element 22 is pressed inwardly. of the toothed track 30, thereby pressing the textile edge 18 against the toothed walls of the toothed track 30. By means of this arrangement, due to the maximum possible pressure force of the spring element 19, it can be ensured that the second tensioning mechanism 7 spring biased is adapted to provide a second maximum tensioning force per unit edge length of the textile material 9 .

It is preferable that the distance between the two opposite curved frame profile elements 13 is at least 2/3 of, preferably greater than and most preferably at least 4/3 of the distance between the two opposite straight frame profile elements 14 . The above-described arrangement of the first and second spring-biased tensioning mechanisms 6, 7 for tensioning the textile material 9 is specifically advantageous for panels having the just-mentioned distance between the two opposite curved frame profile elements 13, because with such dimensions, by means of already known tensioning systems that provide an equal tensioning force per unit edge length of the textile material in both directions of the textile material, it would be very difficult to guarantee that the textile material forms a predicted curvature throughout the length of the peripheral frame between curved frame profile elements. Typically, with known tensioning systems, this would result in the fabric being flattened in a central part of the panel.

Preferably, each curved frame profile element 13 is made of an extruded metal profile 37, preferably made of aluminium, and each curved frame profile element 13 is provided with a number of lateral grooves 38 spaced apart from each other in the longitudinal direction. of the curved frame profile element 13, whereby each side slot 38 extends only partially through the extruded metal profile 37. Thus, by providing flexibility to the extruded metal profile 37 via the side slots 38, a mass-produced extruded profile element can be easily formed to give any desired curvature of an actual building panel frame. Subsequent to the bending of the extruded metal profile 37 provided with lateral grooves 38 to give a desired curvature, the flexible extruded metal profile 37 is reinforced by means of a flat, curved metal plate 39 attached to the extruded metal profile 37 along its length . The curved metal plate 39 may be attached to the extruded metal profile 37, for example, by means of rivets 56 or any other suitable fastening device or method, such as welding. In this way, a rigid curved frame profile member 13 suitable for the frame 2 can be obtained from a mass-produced extruded profile member. The flat, curved metal plate 39 can be easily cut to give the desired curvature, for example by means of a laser cutter, and can compensate for the flexibility of the extruded metal profile 37 provided by the lateral grooves. Thus, conveniently, the same type of extruded profile member can be used to produce both the straight frame profile members 14 and the curved frame profile members 13.

Comparing Figures 11 and 16, it is seen that, in the illustrated embodiment, the same type of extruded profile member has been used to produce both the straight frame profile members 14 and the curved frame profile members 13. It is seen that, therefore, for both the straight frame profile elements 14 and the curved frame profile elements 13, the rounded edge 15 connecting the room-facing side 16 of the frame profile elements 13, 14 frame with the side 17 facing the building of the frame profile elements 13, 14 is arranged on the outer edge of a flange portion extending obliquely downwards in the figures of the frame profile elements 13, 14. In this way, it can be guaranteed that the part of the textile material 9 visible from the room only touches the frame 2 at the rounded edges 15 of the frame profile elements 13, 14. Consequently, a very smooth curved visible textile surface can be obtained.

In order to manufacture a building panel 1 according to the present invention, the frame 2 as partially illustrated in Figure 8 is assembled from the peripheral frame 5 formed by the four frame profile elements 13, 14 described above, as well as two tension profile elements 26, one of which can be seen in the figure, several curved frame profile elements 42 and several straight frame profile elements 43. Each tension profile element 26 is arranged parallel to and at a distance from a curved frame profile element 13 in order to support the first spring biased tensioning mechanism 6 . Curved frame profile elements 42 are arranged parallel to and at a distance from a tension profile element 26 in order to support the frame 2 and possibly support several insulating meshes 8 . The straight frame profile element(s) 43 is/are arranged parallel to and at a distance from the straight frame profile elements 14 in order to support the frame 2 and possibly support several insulating meshes 8 .

Subsequent to the assembly of the frame 2, a textile material 9 is stretched on the room-facing side 3 of the frame 2 between the frame profile elements 13, 14, whereby each edge 18 of the textile material 9 is attached to an element corresponding frame profile by means of a spring biased tensioning mechanism 6, 7. In this way, the extended textile material 9 can form a curved surface 10, 11.

Then, firstly, the textile material 9 is tensioned at a first tensioning force per unit edge length of the textile material relative to each curved frame profile element 13 by means of the first spring-biased tensioning mechanism 6 and , secondly, the textile material 9 is tensioned to a second tensioning force per unit edge length of the textile material in relation to each straight frame profile element 14 by means of the second spring-biased tensioning mechanism 7, by means of so that the first tensile force per unit edge length of the textile material is greater than the second tensile force per unit edge length of the textile material.

Preferably, prior to tensioning the textile material 9 relative to each straight frame profile element 14 by means of the second spring-biased tensioning mechanism 7, the first tensioning force per unit edge length of the textile material provided by the first The spring-biased tensioning mechanism 6 is preferably continuously adjusted by means of the first spring-biased tensioning mechanism 6. The textile material 9 can be a non-woven or woven textile material in the form of a flexible material made up of natural or artificial fibres, yarns or strands. The textile material 9 is preferably made of a material or structure that allows air to diffuse through it.
