Abstract
A sound-absorbing assembly comprising at least one sound-absorbing panel (2) and at least one interwoven cover (4) stably coupled to at least one face of the sound-absorbing panel (2). Said cover comprises two or more swelling elements (7) and two or more fabrics (8) each at least partially wrapped around the visible surface (11) of at least a respective one of the swelling elements (7).
Description
- The present invention is generally applicable to the furniture and services sector and refers to elements of interior cladding, for example, of walls and ceilings.
- In more detail, the present invention refers to a sound-absorbing assembly.
- In the field of furniture, in particular in interior furniture, the use of sound-absorbing panels which are used to clad ceilings and walls is known.
- Generally, the sound-absorbing panels are built by applying a surface decoration (a cover) to the surface of a base material having sound-absorbing performance such as, for example, a rock wool panel.
- Such a surface decoration, in a conventional sound-absorbing panel, can be made by applying a paint directly onto the sound-absorbing substrate. However, by directly applying a paint to the base substrate, a film is formed which impairs its performance, as the sound incident on the sound-absorbing panel is reflected by the paint film itself.
- As a countermeasure to the decrease in the acoustic absorption performance in the prior art, many holes are made on the surface to suppress the reflection of the sound by the coating film. However, this solution is to the detriment of the design which, as a result of the holes, is not appreciated.
- Alternatively, such base panels made of sound-absorbing material may be covered by applying a surface layer to the sound-absorbing substrate to form a surface coating, or by wrapping a breathable material around the panels themselves.
- However, even in these cases, the ability of the sound-absorbing panels to absorb the sounds is greatly impaired by such coatings. In addition, the conventional sound-absorbing panel has a low strength and stiffness and, therefore, the application of such coatings can lead to the bending of the panels themselves with the consequent decrease in the sound-absorbing capacity.
- The object of the present invention is to provide a sound-absorbing assembly that allows to overcome at least partially the drawbacks highlighted above.
- In particular, the object of the present invention is to provide a sound-absorbing assembly comprising a coating that can be coupled to a sound-absorbing panel.
- Another object of the present invention is to provide an assembly whose coating limits, if not eliminates, the decrease in the sound-absorbing performance.
- A further object of the present invention is to provide a sound-absorbing assembly which does not damage the structural integrity of a panel, i.e. which does not cause a decrease in the strength and in the stiffness of the latter.
- Said objects, as well as others which will become clearer below, are achieved by a sound-absorbing assembly according to the following claims, which are to be considered an integral part of the present patent.
- In particular, it comprises at least one sound-absorbing panel and at least one interwoven cover stably coupled to at least one face of the sound-absorbing panel itself.
- According to another aspect of the invention, such a cover comprises two or more swelling elements and two or more fabrics each at least partially wrapped around the visible surface of at least one respective swelling element.
- Advantageously, the assembly of the invention allows to obtain a sound-absorbing panel coupled to a cover that improves its design.
- Unlike the sound-absorbing panels present in the prior art, the fabrics of the invention are not wrapped directly on the sound-absorbing panels, so that, still advantageously, the structural integrity of the sound-absorbing panels is not altered in any way.
- Furthermore, given the presence of the swelling elements, the cover takes on a rounded shape that still advantageously allows to limit the decrease in the sound-absorbing performance compared to the equivalent devices present in the prior art.
- Further features and advantages of the invention will become more evident in light of the detailed description of a preferred but non-exclusive embodiment of a sound-absorbing assembly according to the invention, illustrated by way of nonlimiting example with the aid of the accompanying drawings, in which:
-
FIG. 1 represents the sound-absorbing assembly according to the invention in a view from above; -
FIG. 2 represents a portion of the assembly ofFIG. 1 in an axonometric view. -
FIG. 3 represents a section of the cover of the sound-absorbing assembly ofFIG.1 ; -
FIGs. 4 and 5 represent details of the section ofFIG. 3 . - With reference to the aforementioned figures, a sound-absorbing
assembly 1 is described, as can be seen inFIG. 1 , according to the invention In particular, it comprises a sound-absorbingpanel 2 and aninterwoven cover 4. - According to one aspect of the invention, said
cover 4 is stably coupled to aface 6 of the sound-absorbingpanel 2, generally in the visible face. - According to another aspect of the invention, the
interwoven cover 4, as can be seen inFIG. 3 and in the detail ofFIGs. 4 and 5 , comprisesswelling elements 7 andfabric 8. Obviously, the number of swelling elements and fabrics should not be considered limiting for different embodiments of the invention. - According to the embodiment of the invention that is described, each of the
swelling elements 7 is made as a single flexible body. This advantageously makes it possible to simplify the interweaving operations of thecover 4. - Obviously, this aspect also should not be considered as limiting for different embodiments of the invention where, for example, the swelling elements comprise a plurality of non-homogeneous particles such as polystyrene balls/chips or feathers.
- According to a further aspect of the invention, each
fabric 8 is, at least partially, wrapped around thevisible surface 11 of arespective swelling element 7. - In other words, the
interwoven cover 4 consists of theswelling elements 7 wrapped by means offabrics 8. Theseswelling elements 7 advantageously allow to create acover 4 with a rounded shape, as can be seen inFIG. 2 , which is then coated by thefabrics 8 so as to realize a particular design. - Furthermore, the typical rounded shape of the
cover 4 of theassembly 1 allows, still advantageously, to limit the decrease in the sound-absorbing capacity with respect to the equivalent panels present in the prior art, since, as can be seen in the mentionedFIG. 2 , thecover 4 creates a convexity such as to direct the sound waves towards the sound-absorbing panel and, thus, not to reflect them in the environment. - Furthermore, still advantageously, the weave characterizing the
cover 4 has, unlike the sound-absorbing panels present in the prior art,interstices 15 in thecover 4 that allow the sound waves to reach the sound-absorbingpanel 2. - In addition to this, the sound-absorbing
assembly 1 of the invention allows thecover 4 to be coupled to the sound-absorbingpanel 2 without compromising its structural integrity. - According to the embodiment of the invention that is described, the
fabrics 8 are tubular 18 shaped to contain theswelling elements 7 therein. - In other words, by using the
tubulars 18 thefabrics 8 are no longer wrapped around theswelling elements 7 but the latter are inserted therein. - This advantageously means that the
swelling elements 7 are not compressed by the wrapping of thefabrics 8 and, therefore, there is no risk of deforming or damaging them. - Furthermore, since the
swelling elements 7 are inserted inside thetubulars 18, the risk of them being removed is eliminated, or at least limited. - Moreover, in the event that, as mentioned, such swelling elements are not made as a single body, the use of tubulars allows them to be filled with a plurality of elements since it is the tubular itself that guarantees the compactness and the shape of the swelling elements.
- With regard to the
swelling elements 7, according to an embodiment variant of the invention, not represented in the figures, they also comprise sound-absorbing material. - Advantageously, the presence of sound-absorbing material also in the swelling elements improves the capacity of the
assembly 1. - According to a further aspect of the invention, the
fabrics 8 wrap, at least partially, also the sound-absorbingpanel 2. Advantageously, this makes it possible to improve the coupling between thecover 4 and thepanel 2. - Obviously, also such an aspect must not be considered as limiting for different embodiment variants of the invention where, for example, the fabrics only concern the cover.
- In addition to this, according to different embodiments of the invention not represented in the figures, the assembly also comprises coupling means and a framework that is typically, but not necessarily, constituted by a frame.
- These means are stably coupled to the sound-absorbing panel and are shaped to fix the assembly of the invention to a wall, or to a ceiling, so as, advantageously, to facilitate the operations of implementation of the sound-absorbing assembly of the invention.
- As regards the framework, it is stably coupled to the cover so as to stiffen it in order to advantageously avoid bendings and deformations of the swelling elements and, consequently, of the cover.
- In light of the foregoing, it is therefore understood that the sound-absorbing assembly of the invention achieves all the intended objects.
- In particular, the assembly of the invention allows a sound-absorbing panel to be coated with a cover.
- Furthermore, this is done by limiting the loss of sound-absorbing capacity of the panel compared to equivalent panels present in the prior art.
- Moreover, the cover included in the assembly of the invention is coupled to the panel without damaging its structural integrity or, in any case, limiting possible deteriorations.
- The invention is subject to numerous modifications and variants, which are all included in the appended claims. Moreover, all the details and steps may furthermore be replaced by other technically equivalent elements, and the materials may be different depending on needs, without departing from the protection scope of the invention defined by the appended claims.
