Description

The invention initially relates to a plurality of plate-shaped sound absorption elements for ceiling or wall-parallel installation in a room, each sound absorption element having a base plate and a plurality of applied to the base plate, spatially free-standing structural elements.

Furthermore, the invention relates to a plate-shaped sound absorption element for ceiling or wall-parallel installation in a room, wherein the sound absorption element has a base plate and a plurality of applied to the base plate, room side freestanding structural elements.

Sound absorption elements of the type in question are known. These are initially plate-shaped, with free from the plate in the direction of the space freely projecting structural elements, in particular absorber structural elements. It is further known in this respect to design the structural elements differently with respect to a length considered perpendicular to the base plate so as to achieve an overall structured surface of the sound absorption element facing the space.

To cover large ceiling or wall surfaces several, preferably the same design plate-shaped sound absorption elements are arranged like a tile. The mutually facing edge edges, in particular in the region of the baseplates of the sound absorption elements, preferably lie against one another over the entire area.

With regard to the known prior art, a technical problem of the invention is seen in further improving a sound absorbing element of the type in question.

A possible solution of the problem is given according to a first concept of the invention in a plurality of plate-shaped sound absorption elements, which is based on the fact that the plurality of sound absorption elements with respect to the formation of an edge contour are the same, which over a length of the edge of a base plate deviating from a straight line extending edge contour with the edge contour of a peripheral edge of another sound absorbing element mates.

It is thus in the assembled and assembled state of the plurality of sound absorbing elements a homogeneous appearance of the overall construction achievable. The structures of the individual sound absorption elements can thus be designed to run into one another.

It can further be provided that the edge contour deviating from a straight line is formed two or more times on the same sound absorption element, but with the difference between two configurations that a positive projection of one edge edge profile fits into a negative projection of the other edge edge profile, so that several more configured sound absorption elements in a ceiling or wall design at the marginal edges are fit together into one another.

The marginal edges of a sound absorption element along an imaginary, corner regions of the base plate connecting lines in a floor plan, in which plan the edge represents a line may have positive or negative protrusions in the manner of projections and / or recesses relative to the straight line in the assembled state can engage with corresponding rear and / or projections or negative and / or positive projections of the adjacent sound absorption element. In this way, an at least not immediately recognizable edge contour between two adjacent sound absorption elements is given, which results in a closed, optically not by straight, continuous edge edge lines possibly disturbed appearance.

The positive and / or negative projections may be formed in the plan view circular or polygonal edge section contours.

Furthermore, in particular projections of the edge contour can be formed in continuation beyond the base plate by structural elements, in particular absorber structural elements.

The plate-shaped sound absorption elements engage positively in the region of the mutually facing edge edges. This offers advantages in the course of assembly. In addition, the design claim of a "closed" ceiling can be fulfilled.

A further solution of the problem is given in a plate-shaped sound absorption element, in which is based on that a structural element is designed as a cylinder, with a preferably perpendicular to the plane of the base plate body axis and that on the sound absorption element, a plurality of cylinders of different diameters and / or Lengths are arranged.

The structural elements may be circular cylindrical elements. Thus, a structural element may have a circular floor plan. Also elliptical or oval floor plans can be given. The elements, in particular the absorber structural elements, preferably consist of a foam material, such as, for example, open-cell foam, preferably melamine resin foam.

The body axis of a structural element may also be at an acute angle to the base plate plane, for example an angle of 5 to 89 degrees, further including, for example, 30 to 75 degrees of base plate plane.

The structural elements are exposed on the room side, so that there is an immediate transition from the outside to the room. In a ceiling arrangement of the sound absorption element then the base plate above and the structural elements below, pointing to the room.

The cylindrical structural elements of a sound absorption element may have different diameters and / or lengths measured perpendicular to the plane extent of the base plate. It can be provided on a sound absorbing element several structural elements with the same diameters and equal lengths, but possibly also with the same diameters and different lengths or different diameters and equal lengths.

The length of a structural element may correspond to 0.2 to 20 times or more, up to, for example, 100 times the diameter of the structural element.

Especially with structural elements that are round in plan, different depths result, also due to the possible different lengths, which also lead to a large surface area and thus to an advantageous absorber effect.

Also, one or more structural elements may be formed as functional parts. Such a functional part preferably also has a cylindrical, for example circular-cylindrical shape, corresponding optically adapted to the shape of the further structural elements possibly surrounding the functional part.

Functional elements are in particular active or activatable elements, more preferably electrically, mechanically or electromechanically activatable elements.

A functional part may be a lighting element and / or a smoke detector and / or a loudspeaker and / or a heating element and / or a fan or contain such an element.

The functional part can also have absorption properties in one embodiment.

A structural element (absorber structural element and / or structural element in the form of a functional part) may, for example, be connected to the base plate as a result of adhesive bonding. Such bonding can be made blunt on the surface of the base plate facing in the use position of the room side.

Also, a structural element can be embedded in the base plate. For this purpose, the base plate may, for example, have a depression which, in terms of plan view, is preferably adapted to the cross-sectional configuration of the structural element to be retained. In a preferred circular cylindrical design of the structural element may be provided correspondingly a cup-shaped, circular in plan view recess.

In a further embodiment, the structural element can also enforce the base plate. For this purpose, the base plate has an opening passing through the broad surfaces of the base plate, for example a circular opening in the form of a bore whose diameter is preferably adapted to the outer diameter of the cylindrical structural element to be accommodated. The structural element can pass through the base plate and aligned with its end face with the broadside of the base plate facing away from the room in the use position.

Also, the structural element may extend beyond the in use position facing away from the room broadside surface of the base plate outstanding.

Each structural element and / or a functional part may have a closing surface parallel to the plane of the base plate on the room side. In a preferred circular-cylindrical configuration of the structural elements and / or the functional parts, correspondingly circular-disk-shaped end surfaces result accordingly. These end surfaces are in the use position of the sound absorption elements visible surfaces.

The end surface may also extend at an acute angle to a longitudinal axis of the structural element beyond. In a circular cylindrical element, this results in an elliptical end surface.

Gaps or spacing spaces remaining between the structural elements and / or functional parts can be formed continuously up to a room-side surface of the base plate. It revealed so correspondingly deep spaces, which contribute to a beneficial absorber effect.

Also, individual structural elements may be arranged adjacent to each other over their length. A structural element or even a functional part can touch one, two, three or four, possibly even more, up to ten neighboring structural elements and / or functional parts. This contact can be given like a line to the room-side surface of the base plate.

The base plate may consist of a foam, for example a particle foam, in particular a high-density particle foam having a weight of 30 to 100 kg / m ³ .

Also, the base plate made of wood, for example. From a solid wood panel or further example. Chipboard. Furthermore, the base plate of a plastic material, such as. ABS exist. It is also possible to form the base plate as a plasterboard.

The base plate of the sound absorption element may have a round, oval or polygonal, such as square, elongated rectangular, dreioder pentagonal floor plan. The floor plan here refers to a straight line connecting by corner points of the base plate on the shortest path.

The floor plan surfaces of several sound absorbing elements for clothing a wall or a ceiling can be chosen differently.

The structural elements of a sound absorption element may have the same or different ground plan geometries and / or colors.

In addition, in the case of a plurality of sound absorption elements for arrangement, for example, on a ceiling, the structural elements of a sound absorption element may be the same in plan view but at least different from another sound absorption element.

The diameter d of a structural element 3 preferably corresponds at least to the thickness b of the base plate 2 , more preferably a multiple of the thickness b. Thus, the diameter d may be 1.5 to 6 times or more the base plate thickness b.

The length c considered perpendicular to a floor plan surface preferably corresponds to 0.5 to 20 times the diameter d.

They are structural elements 3 different diameter d and lengths c provided. Part of the structural elements 3 may in this case have the same diameter and / or lengths.

The arrangement in the position of the sound absorption element 1 the surface facing the room 5 of each structural element 3 can according to the configuration of the structural element 3 be disc-shaped, in this case preferably parallel to the plane of the base plate 2 (see. 26 ,

The closing surface 5 can also be at an acute angle, for example. At an angle of 30 ° or 45 °, to the body axis x of the structural element 3 run, so that in a circular cylindrical structural element 3 an elliptical finish 5 results (cf. 27 ).

The arrangement of the structural elements 3 on the base plate 2 can be further selected so that adjacent structural elements 3 over its length c, in particular over the length c of the shorter structural element 3 , abut each other. This results from the circular cylindrical design of the structural elements 3 a preferred line-like touch.

A structural element 3 can touch one or more adjacent structural elements. Also, a structural element 3 with transverse to the longitudinal distance considered distance to an adjacent structural element 3 be arranged.

Anyway arise between the structural elements 3 gore 6 or space spaces extending to the room side surface 7 the base plate 2 extend continuously.

The attachment of the structural elements 3 at the base plate 2 Can be done by gluing.

According to the sectional view in 10 Can be a dull arrangement and bonding be provided. For this sits the structural element 3 on the room side facing surface 7 the base plate 2 on and is glued to this.

Also, as shown in FIG 11 the structural element 3 partly in the base plate 2 be admitted. For this purpose, one to the outline contour of the structural element 3 adapted recess 8th provided, which of the area 7 goes out and about one third to two thirds, for example, more than half of the base plate thickness b extends. The structural element 3 is, for example, in the depression 8th glued.

Further alternatively, the structural element 3 as shown in 12 the base plate 2 push through. For this purpose, the base plate 2 one to the outline contour of the structural element 3 adapted breakthrough 9 on. In this sits the structural element 3 one foot and is, for example, circumferentially along the breakthrough edge with the base plate 2 bonded.

The the closing surface 5 opposite end face of the structural element 3 preferably closes with the rear surface of the base plate in such an embodiment 2 flush off. Further alternatively, the structural element 3 be arranged also protruding beyond the rear surface.

The structural elements 3 are preferably absorber structural elements. These may, as also preferred, consist of a melamine foam. More preferably, such a melamine foam is not laminated.

The structural elements 3 can be formed differently colored or colored.

Next can be structural elements 3 also as functional parts 10 be formed or such functional parts 10 contain. So are the functional parts 10 preferably the same design the absorber structural elements 3 , namely preferably as a circular cylinder.

functional parts 10 can be, for example, odor filters, smoke detectors, lighting elements or motion detectors. Next, such functional parts 10 also serve for extraction or as heating or air conditioning connections.

As shown in 1 can use several sound absorbing elements 1 to increase the total sound absorption area are arranged side by side.

According to the in the 1 to 12 The first embodiment shown are the marginal edges 4 formed rectilinearly, extend along a straight line accordingly.

The 13 to 22 show embodiments in which the edge contour over the length of the peripheral edge 4 deviating from a straight line. It is about the longitudinal extent of the marginal edge 4 with respect to an imaginary straight line G, projections and recesses or positive projections 11 and negative protrusions 12 provided in the edge contour.

These positive projections 11 and negative protrusions 12 may have circular disc segment-like shapes, alternatively polygonal shapes.

The over the straight line G beyond positive projections 11 the edge contour are preferably formed by over the straight line extending beyond structural elements 3 and their axial extension in the base plate 2 , With reference to a floor plan according to 15 the straight line G penetrates these structural elements 3 secant.

The over the straight line G protruding structural elements 3 or the contour projections formed thereby are received by appropriately adapted trained negative projections 12 an adjacent base plate 2 or an adjacent sound absorption element 1 ,

Every positive advantage 11 a marginal edge 4 a sound absorption element 1 is a negative lead 12 a to be applied adjacent sound absorption element 1 assigned.

This results in an arrangement of a plurality of sound absorption elements 1 a spreading of structural elements 3 in the plane defined by the straight line G surface of the adjacent sound absorption element 1 ,
