DETAILED DESCRIPTION

[0062] The present inventive concept will now be described more fully hereinafter with reference to the accompanying drawings, in which preferred variants of the inventive concept are shown. This inventive concept may, however, be embodied in many different forms and should not be construed as limited to the variants set forth herein; rather, these variants are provided for thoroughness and completeness, and fully convey the scope of the inventive concept to the skilled person. Like reference numerals refer to like elements throughout the description.

[0063] Initially a tile system in form of a suspended ceiling system 100, including absorber tile elements, will be described with reference to FIGS. 1-4. Followingly a baffle system 200 will be described with reference to FIG. 5.

[0064] FIG. 1 is a schematic perspective view of conceptually depicting a tile system 100 including in form of a suspended ceiling system 100. For reasons of simplicity there are six planar absorber tile elements or objects in form of ceiling tiles 102a-f illustrated in FIG. 1. It is however to be understood that any number of absorber tile elements, e.g. ceiling tiles, may be used according to the present inventive concept. Each ceiling tile 102a-f has a first major surface intended to face an interior of a room and an opposing second major surface. Further, each ceiling tile 102a-e has four side edge surfaces 109a-e extending between the respective first and second major surfaces. However, ceiling tile 102f has a single side edge surface 109f circumferencing the ceiling tile 102f at an outer periphery thereof and extending between the first and second major surfaces.

[0065] FIG. 1. Illustrates how the ceiling tiles 102a-f, forming a suspended ceiling, are suspended from a structural ceiling of a building, not shown.

[0066] Each ceiling tile 102a-f is suspended by means of suspension elements 104a-f, 104x in form of wires. Other relevant examples of suspension elements are a line, a cable, a cord, a thread, a rod, a string, a chain, a rope or a combination thereof. The ceiling tiles 102a-d are suspended using four suspension elements 104a-d each. Ceiling tile 102e is suspended using five suspension elements 104e, whereas ceiling tile 102f is suspended using three suspension elements 104f. Each suspension elements 104a-f are attached to the ceiling tiles in corresponding attachment points. Each attachment point includes an anchor element 106a-f.

[0067] Ceiling tile 102f is suspended below ceiling tile 102e, in the sense that ceiling tile 102f is located further below the structural ceiling and partially under ceiling tile 102e. Ceiling tiles 102e and 102f share one suspension element 104x, which is used for suspending both ceiling tile 102e and ceiling tile 102f. The depicted suspension element 104x is a wire like suspension elements 104a-f.

[0068] The ceiling tiles 102a-f comprises compressed fiber material. Suitable examples of compressed fiber material are mineral fiber material, such as glass wool, mineral wool and stone wool. Other examples of suitable compressed fiber material are wood fiber, textile fiber, polymer fiber and metal fiber. However other materials are also conceivable without departing from the scope of the inventive concept. Ceiling tiles comprising the exemplified materials are known to exhibit acoustic properties such as sound absorbing properties.

[0069] As can be seen in FIG. 1, the ceiling tiles 102a-f are of different sizes and different shapes. Ceiling tiles 102a-d are all of a square shape and are of the same size. Ceiling tile 102e on the other hand is larger compared to ceiling tiles 102a-d. Also, ceiling tile 102e is in the form of a square. Ceiling tile 102f on the other hand is exhibiting a circular shape. As is evident, the size of and shape of the ceiling tiles 102a-f may be altered into any size and shape without departing from the scope of the present inventive concept. Also, the arrangement in terms of how the respective ceiling tiles 102a-f are suspended with respect to each other and the room in which they are present may be altered to suit the needs presently at hand. For instance, the ceiling tiles 102a-f may be arranged at different heights and/or may be inclined relative each other.

[0070] In FIG. 1 the ceiling tiles 102a-f are illustrated as being free hanging, meaning that the respective ceiling tiles 102a-f are not in contact with each other. It is however possible to arrange the ceiling tiles 102a-f such that the respective ceiling tiles 102a-f are in contact with neighboring ceiling tiles or some of the neighboring ceiling tiles.

[0071] Further, the ceiling tiles 102a-f may be provided with a layer, not shown, on the side facing the interior of the room in which the ceiling tiles 102a-f are suspended. The layer may in turn be provided with decorative elements such a paint, a print, a sticker or similar. In other words, the appearance of the ceiling tiles 102a-f may be altered to suit the needs of a particular installation.

[0072] It will now be described in greater detail, with reference to FIGS. 2a and 2b, how suspension element 104a is used to suspend ceiling tile 102a by being connected to the ceiling tile 102a by means of anchor element 106a. Also, the design of the anchor element 106a will be described in greater detail. Although the below description will be made with reference to ceiling tile 102a, suspension element 104a and anchor element 106a, the below description is equally valid for any of the ceiling tiles 102a-f, any of the suspension elements 104a-f and any of the anchor elements 106a-f.

[0073] In FIGS. 2a and 2b it is depicted how anchor element 106a is screwed into ceiling tile 102a, at the second major surface 108a thereof. The first major surface 107a is facing the interior of the room in which the ceiling tile 102a is suspended. The anchor element 106a is screwed into the ceiling tile 102a such that the anchor element 106a becomes completely recessed in the ceiling tile 102a. As is depicted, the second major surface 108a is deflected at the location of the anchor element 106a, such that the anchor element 106a becomes recessed in the ceiling tile 102a.

[0074] The depicted anchor element 106a of FIGS. 2a and 2b comprises a head portion 110a and a threaded portion 112a. The head portion 110a is located above the threaded portion 112a.

[0075] The threaded portion 112a includes a thread 120a.

[0076] In the depicted anchor element 106a the head portion 110a and the threaded portion 112a partially overlap in a direction along a central axis CA of the anchor element 106a. In other words, the thread 120a of the threaded portion 112a extends onto the head portion 110a.

[0077] The thread of the depicted anchor element 106a is conical in the sense that its radius increases towards the head portion 110a. The depicted thread 120a has a radius of 10 mm at its starting point and a radius of 16.6 mm at its end point, i.e. where the thread 120a terminates at the head portion 110a. The pitch of the thread 120a is 6 mm. This means that the separation between consecutive turns of the thread 120a is 6 mm. Examples of feasible pitches are between 4 and 10 mm. The periphery of the thread 120a is preferably relatively speaking sharp so as to cut through the material of the ceiling tile 102a, thereby facilitating its insertion into the ceiling tile 102a. Also, the conical design of the thread 120a facilitates its insertion into the material of the ceiling tile 102a.

[0078] In the depicted anchor element 106a the head portion 110a and the threaded portion 112a are integrally formed by being molded. Suitable materials for the anchor element 106a include polymers, fiber reinforced polymers and metals to give a few non-limiting examples. However other materials are also conceivable without departing from the scope of the inventive concept. Anchor elements 106a comprising the exemplified materials are known to exhibit desirable material properties. The head portion of the depicted anchor element 106a has a diameter of 37 mm. However, diameters in the range of 10-100 mm are generally feasible depending e.g. on the thickness and weight of the ceiling tile 102a to be suspended.

[0079] The depicted anchor element 106a of FIGS. 2a and 2b comprises a wire lock 114a arranged in the anchor element 106a. The wire lock 114a is arranged in the anchor element 106a such that the wire lock 114a is recessed in the ceiling tile 102a together with the head portion 110a. The wire lock 114a has an access port 118a accessible from a top side 116a of the head portion 110a. The depicted wire lock 114a is of a one-way type meaning that suspension element 104a may be inserted and fed through the access port 118a without having to release the wire lock 114a. However, the suspension element 104a is prevented from being pulled back and out of the wire lock 114a without releasing the wire lock 114a.

[0080] The depicted wire lock 114a comprises a biased release member 119a. The release member 119a of the depicted wire lock 114a is protruding beyond the top surface 116a of the head portion 110a. The release member 119a is provided with the access port 118a. The release member 119a may be pushed back in order to release the suspension element 104a or suspension wire 104a. The release member 119a may be pushed back such that it becomes flush with the top surface 116a of the head portion 110a. This implies that absorber tile elements 102a may be stacked on top of each other with a reduced risk that the anchor elements 106a of the absorber tile elements 102a damages neighboring absorber tile elements 102a. Hence, the anchor element 106a is suitable for being pre-mounted to absorber tile elements 102a.

[0081] The depicted wire lock 114a is threaded into the anchor element 106a. For that reason, the wire lock 114a is provided with an external thread and the head portion 110a of the anchor element 106a is provided with a cavity having an internal corresponding thread.

[0082] Different types of wire locks 114a may be used. Wire locks 114a locking the wire in both directions may be used to advantage. For instance, wire locks 114a utilizing screws to lock the wire 104a may be used.

[0083] As is seen in FIGS. 2a and 2b, in particular in FIG. 2b, the wire lock 114a defines an internal wire lock channel 115a terminating in the access port 118a at a first end and in an outlet port 117a at a second end. The anchor element 106a defines an internal anchor element channel 105a. In the depicted wire lock 114a the anchor element channel 105a is adjoining the outlet port 117a. The anchor element channel 105a is configured to guide a suspension wire 104a through the anchor element 106a. Hence, the anchor element channel 105a is configured to guide a suspension wire 104a which has been passed through the wire lock 114a and introduced into the anchor element channel 105a through the anchor element 106a. This means that a suspension wire 104a may be passed into the access port 118a, through the internal wire lock channel 115a, into and through the anchor element channel 105a and finally out of the anchor element 106a, as can be seen in FIG. 2b.

[0084] As is seen in FIGS. 2a and 2b, in particular in FIG. 2b, the anchor element channel 105a of the depicted anchor element 106a is configured to guide the suspension wire 104a through the anchor element 106a such that the suspension wire 104a is deflected in a direction towards the top side 116a of the head portion 110a. Hence, the anchor element channel 105a will deflect and bend a suspension wire 104a being fed therethrough such that the suspension wire 104a exits the anchor element channel 105a in a direction out of the top side or top surface 116a of the head portion 110a. The anchor element channel 105a will typically deflect the suspension wire 104a with a bending radius in the range of 5-20 mm. A bending radius range of 5-mm allows for that a suspension wire 104a having a desired thickness may be used in the sense that the suspension wire 104a is bent and deflected easily when being fed and guided through the anchor element channel 105a. However, any bending radius in the range of 3-40 mm may be used to advantage.

[0085] The depicted suspension wire 104a of FIGS. 2a and 2b typically has a diameter in the range of 0.5-3 mm. Preferably a diameter of 0.7-1.2 mm is chosen since a diameter within this range allows for a desired strength while still providing a wire flexible enough to easily be fed and guided through the anchor element channel 105a. A diameter in the range of 0.5-3 mm may be used to advantage for any of the suspension elements 104a-f, 104x of FIG. 1.

[0086] As is seen in FIGS. 2a and 2b the head portion 110a of the depicted anchor element 106a is provided with mounting tool recesses 126a. More specifically, the head portion 110a is provided with two mounting tool recesses 126a. Any number of mounting tool recesses 126a may be used to advantage. By providing at least one mounting tool recess 126a accessible by a mounting tool from a top side 116a of the head portion 110a, mounting of the anchor element 106a to the absorber tile element 102a may be significantly simplified since a tool may be used to screw the anchor element 106a into the absorber tile element 102a. A tool having two protrusions may conveniently be inserted into the two mounting tool recesses 126a where the tool may engage the head portion 110a of the anchor element 102a, thus enabling a simplified turning of the anchor element 102a.

[0087] The depicted anchor element 106a has a length, i.e. an extension along the central axis CA of the anchor element 106a, of 32.5 mm. Typical feasible lengths are between 10-150 mm, depending e.g. on the thickness of the ceiling tiles to be suspended.

[0088] It will now be described in greater detail, with reference to FIGS. 3a and 3b, how suspension element 104b is used to suspend ceiling tile 102b by being connected to the ceiling tile 102b by means of anchor element 106b. The design of the anchor element 106b which is different from the anchor element 106a of FIGS. 2a and 2b will be described in greater detail. Although the below description will be made with reference to ceiling tile 102b, suspension element 104b and anchor element 106b, the below description is equally valid for any of the ceiling tiles 102a-f, any of the suspension elements 104a-f and any of the anchor elements 106a-f.

[0089] In FIGS. 3a and 3b it is depicted how anchor element 106b is screwed into ceiling tile 102b, at the second major surface 108b thereof. The anchor element 106b is screwed into the ceiling tile 102b such that the anchor element 106b becomes recessed in the ceiling tile 102b. As is depicted, the second major surface 108b is flat, i.e. not deflected, at the location of the anchor element 106b. Hence, a top portion of the anchor element 106b protrudes slightly above the second major surface 108b.

[0090] The depicted anchor element 106b of FIGS. 3a and 3b comprises a head portion 110b and a threaded portion 112b, like the anchor element 106a of FIGS. 2a and 2b.

[0091] The head portion 110b is located above the threaded portion 112b. In the depicted anchor element 106b the head portion 110b and the threaded portion 112b are integrally formed by being molded. The head portion of the depicted anchor element 106b has a diameter of 37 mm. However, diameters in the range of 10-100 mm are generally feasible depending e.g. on the thickness and weight of the ceiling tile to be suspended, as discussed above.

[0092] The length of the anchor element 106b is similar to the length of the anchor element 106a of FIGS. 2a and 2b, as described above.

[0093] The threaded portion 112b includes a thread 120b. The thread 120b is similar to the thread 120a of FIGS. 2a and 2b described above, why the thread 120b will not be described in greater detail to avoid undue repetition.

[0094] In the depicted anchor element 106b of FIGS. 3a and 3b, the head portion 110b comprises a wire lock holding member 124b supporting the wire lock 114b. The depicted wire lock holding member 124b is a socket which is attached to the head portion 110b. Hence, the wire lock holding member 124b is formed separately from the head portion 110b and the threaded portion 112b of the anchor element 106b, and subsequently fastened to the head portion 110b. The depicted wire lock holding member 124b includes the anchor element channel 105b. The wire lock holding member 124b may include the anchor element channel 105b or may not include the anchor element channel 105b. The wire lock 114b is in turn press fitted into the wire lock holding member 124b. More specifically, the wire lock 114b is press fitted into the wire lock holding member 124b of the anchor element 106b such that the wire lock 114b is recessed in the ceiling tile element 102b together with the head portion 110b. Different designs, sizes and fastening techniques of the wire lock holding member 124b may be used to advantage. Other fastening techniques include soldering, welding or gluing to give a few non-limiting examples.

[0095] In the depicted anchor element 106b of FIGS. 3a and 3b, a biased release member 119b is located below the top surface 116b of the head portion 110b. Hence, the complete wire lock 114b is located below the top surface 116b of the head portion 110b such that the wire lock 114b is housed within the anchor element 106b.

[0096] The depicted wire lock 114b of FIGS. 3a and 3b defines an internal wire lock channel 115b like the wire lock 114a of FIGS. 2a and 2b. The internal wire lock channel 115b will consequently not be described in greater detail to avoid undue repetition.

[0097] Similarly, the anchor element 106b of FIGS. 3a and 3b defines an anchor element channel 105b like the anchor element 106a of FIGS. 2a and 2b. The anchor element channel 105b will consequently not be described in greater detail to avoid undue repetition.

[0098] As is seen in FIGS. 3a and 3b the head portion 110b of the depicted anchor element 106b is provided with a mounting tool recess 126b. More specifically, the head portion 110a is provided with a mounting tool recess 126b in form of a hexagonal recess. Hence, a hex-key may be used to screw the anchor element 106b into the absorber tile element 102b.

[0099] Now referring to FIG. 4, here it is conceptually depicted in greater detail how ceiling tiles 102e and 102f are suspended using the common suspension element 104x, and respective anchor elements 106e and 106f.

[0100] Anchor element 106f used for suspending ceiling tile 102f is of the same type as anchor element 102a described above in relation to FIGS. 2a and 2b. Hence, anchor element 102f will not be described in greater detail to avoid undue repetition.

[0101] Anchor element 106e used for suspending ceiling tile 102e is similar to anchor element 102a described above in relation to FIGS. 2a and 2b. The anchor element channel 105e of anchor element 106e is formed differently as compared to the anchor element channels 105a and 105f. However, the wire lock channels 115e and 115f are both formed as the wire lock channel 115a of FIGS. 2a and 2b.

[0102] More specifically, the anchor element channel 105e of anchor element 106e is a straight anchor element channel 105e. The anchor element channel 105e extends along a central axis CA of the anchor element 106e.

[0103] Anchor element channel 105e is configured to guide the suspension wire 104x through the anchor element 106e such that the suspension wire is guided in a direction towards a bottom side 113e of the threaded portion 112e. Hence, when suspension wire 104x is guided through the anchor element 106e the suspension wire 104x will exit the anchor element 106e at the bottom thereof. The suspension wire 104x may as is depicted in in FIG. 4 penetrate the absorber tile element 102e and exit the absorber tile element 102e at its first major surface 107e i.e. the surface facing the interior of the room in which the ceiling tile 102e is suspended. From there the suspension wire 104x may continue to another anchor element, like anchor element 106f in FIG. 4.

[0104] By this arrangement, ceiling tile 102e is suspended above ceiling tile 102f using the common suspension element 104x, as described above. It is to be understood that three or more ceiling tiles may be suspended after each other in a vertical direction using a common suspension element 104x as described above.

[0105] Now referring to FIG. 5, here is conceptually depicted a tile system 200 in form of a baffle system 200. For reasons of simplicity there is a single planar tile in form a baffle 202a illustrated in FIG. 5. It is however to be understood that any number of baffles 202a may be used according to the present inventive concept. The baffle 202a has a first major surface 207a and an opposing second major surface. Further, the baffle 202a has four side edge surfaces 209a extending between the respective first 207a and second major surfaces.

[0106] The baffle 202a, comprises compressed fiber material. Suitable examples of compressed fiber material are mineral fiber material, such as glass wool, mineral wool and stone wool. Other examples of suitable compressed fiber material are wood fiber, textile fiber, polymer fiber and metal fiber. However other materials are also conceivable without departing from the scope of the inventive concept. Ceiling tiles comprising the exemplified materials are known to exhibit acoustic properties such as sound absorbing properties.

[0107] The baffle 202a is suspended by means of two suspension elements 204a in form of wires. Other relevant examples of suspension elements are a line, a cable, a cord, a thread, a rod, a string, a chain, a rope or a combination thereof. Each suspension element 204a is attached to the baffle 202a in corresponding attachment points. Each attachment point includes an anchor element 206a. The anchor elements 206a are of the type described above in conjunction with FIGS. 2a and 2b. Accordingly, the anchor elements 206a will not be described in detail below to avoid undue repetition.

[0108] The anchor elements 206a are screwed into one of the side edge surfaces 209a of the baffle 202a. By screwing the anchor elements 206a into one of the side edge surfaces 209a the baffle 202a may be vertically suspended as illustrated in FIG. 5.

[0109] As is understood, the respective types of anchor elements 106a-f described above may be interchanged with each other to suit specific installation needs. Hence, a suspended ceiling may include a plurality of types of anchor elements 106a-f. Similarly, a suspended ceiling may include a single type of anchor elements 106a-f. The anchor elements 106a-f described may advantageously be used to fasten or suspend vertically arranged panels or tiles, such as sound absorbing baffles 202a, as described above. Also, a tile system 100, 200 may include different types of tiles, such as ceiling tiles 102a-f and baffles 202a. In other words, a single tile system 100, 200 may for instance include a number of ceiling tiles 102a-f and a number of baffles 202a to give an example.

[0110] It will be appreciated that the present inventive concept is not limited to the variants shown. Several modifications and variations are thus conceivable within the scope of the invention which thus is defined by the appended claims.
