"PANNELLO FONOASSORBENTE" "SOUND ABSORBING PANEL"

DESCRIZIONE DESCRIPTION

Il trovato si riferisce al campo dei pannelli per arredamento. Sono noti e già usati pannelli per arredamento a fori passanti costituiti da uno strato centrale di fibra di legno o pasta di legno o simili, ad alta o media densità e una impiallacciatura sulle due superfici maggiori. Un tipo di tali pannelli è posto sul mercato da Locatelli Laminati SaS di Locatelli Uberto & C. Tali pannelli hanno uno spessore inferiore o uguale a 6 mm. Vengono generalmente utilizzati a scopo decorativo, per ante di armadi per separazione di ambienti e dove in genere si desideri permettere un certo passaggio di luce ed aria e una visione parziale. The invention relates to the field of furniture panels. Through-hole furnishing panels are known and already used consisting of a central layer of wood fiber or wood pulp or the like, of high or medium density and a veneer on the two major surfaces. One type of such panels is placed on the market by Locatelli Laminati SaS of Locatelli Uberto & C. These panels have a thickness of less than or equal to 6 mm. They are generally used for decorative purposes, for cabinet doors to separate rooms and where a certain passage of light and air and a partial vision are generally desired.

Sono anche noti materiali fonoassorbenti a foglio, ad esempio tessuti non tessuti, espansi e simili, di cui però la possibilità di assorbimento del rumore è significativa al di sopra dei 20 mm. Foil sound-absorbing materials are also known, for example non-woven fabrics, foams and the like, of which however the possibility of noise absorption is significant above 20 mm.

Un obiettivo nel campo dell'edilizia è ottenere effetti di fonoassorbenza sempre migliori con un ingombro e un peso relativamente esigui. A goal in the building field is to obtain better and better sound absorption effects with a relatively small footprint and weight.

Il trovato, come è definito nella rivendicazione 1, risolve il problema sopra posto e consegue un'ottima fonoassorbenza con uno spessore esiguo e un buon aspetto estetico. The invention, as defined in claim 1, solves the above problem and achieves excellent sound absorption with a small thickness and a good aesthetic appearance.

Il nuovo pannello comprende uno strato d'anima di materiale di legno compresso rivestito su entrambe le facce di impiallacciatura di legno, tale strato essendo dotato di fori passanti, e uno strato di materiale fonoassorbente, comprendente un foglio . di tessuto non tessuto, incollato su una faccia impiallacciata. I fori passanti possono essere in forma quadrata, rettangolare o rotonda, preferibilmente con un rapporto vuoti su pieni non inferiore al 15%. The new panel comprises a core layer of compressed wood material coated on both faces with wood veneer, this layer being provided with through holes, and a layer of sound-absorbing material, comprising a sheet. of non-woven fabric, glued on a veneered face. The through holes can be square, rectangular or round, preferably with a void to full ratio of not less than 15%.

Il trovato consegue gli obiettivi menzionati sopra. The invention achieves the objectives mentioned above.

Un esempio di realizzazione del trovato sarà dato in seguito con riferimento ai disegni allegati in cui è illustrato e nei quali: An example of embodiment of the invention will be given below with reference to the attached drawings in which it is illustrated and in which:

La figura 1 è una vista prospettica di un pannello fonoassorbente secondo il trovato, illustrato interrotto; Figure 1 is a perspective view of a sound-absorbing panel according to the invention, illustrated interrupted;

la figura 2 è una sezione secondo il piano indicato con 2-2 in figura 1, ingrandita rispetto a detta figura; Figure 2 is a section along the plane indicated with 2-2 in Figure 1, enlarged with respect to said figure;

la figura 3 è una sezione, simile alla figura 2, di una variante del pannello. Il pannello del trovato è indicato complessivamente con il riferimento 10. Esso comprende uno strato 12 in legno o materiale tipo legno e uno strato 14 in materiale fonoassorbente. Lo strato in materiale ligneo 12 comprende un'anima 16 in fibra di legno o simili, compatto, vale a dire con una densità da 500 a 1100 kg/m^ e due fogli di impiallacciatura sulle due facce maggiori, indicati rispettivamente con 18 e 20. Lo strato 12 in materiale ligneo presenta una distribuzione di fori passanti 22, in questo caso una distribuzione regolare di fori quadrati con un rapporto vuoto/pieno di circa il 25%. Ovviamente la forma dei fori può essere differente, ad esempio rotonda, poligonale, ecc... I fori dello strato 12 risultano coperti o chiusi, su una faccia dello strato di legno, dal foglio di materiale fonoassorbente 14. Figure 3 is a section, similar to Figure 2, of a variant of the panel. The panel of the invention is indicated as a whole with the reference number 10. It comprises a layer 12 made of wood or a wood-like material and a layer 14 of sound-absorbing material. The layer of wood material 12 comprises a core 16 in wood fiber or similar, compact, that is to say with a density from 500 to 1100 kg / m ^ and two sheets of veneer on the two major faces, indicated respectively with 18 and 20 The layer 12 of wooden material has a distribution of through holes 22, in this case a regular distribution of square holes with an empty / full ratio of about 25%. Obviously the shape of the holes can be different, for example round, polygonal, etc ... The holes of the layer 12 are covered or closed, on one face of the wood layer, by the sheet of sound-absorbing material 14.

Preferibilmente lo strato di legno ha uno spessore da 0,5 a 1 mm. Preferably the wood layer has a thickness of 0.5 to 1 mm.

Il materiale fonoassorbente 14 può essere un materiale a foglio reperibile sul mercato ad esempio un tessuto non tessuto in poliestere, e/o cellulosa, e/o polipropilene, ecc. In aggiunta al foglio 14 può essere applicato sul pannello un ulteriore foglio o lastra 24 di materiale fonoassorbente (figura 3) per migliorare la resa. L'applicazione del foglio 14 e del foglio 24 può essere realizzata in qualsiasi modo noto, ad esempio mediante incollaggio. The sound-absorbing material 14 can be a sheet material available on the market, for example a non-woven fabric made of polyester, and / or cellulose, and / or polypropylene, etc. In addition to the sheet 14, a further sheet or plate 24 of sound-absorbing material (Figure 3) can be applied to the panel to improve the yield. The application of the sheet 14 and of the sheet 24 can be carried out in any known way, for example by gluing.

Si è rilevato che il pannello fonoassorbente 10 così realizzato presenta livelli di assorbimento del rumore particolarmente elevati, superiori a quello che sarebbe logico aspettarsi da una combinazione dei due elementi di base (pannello forato e foglio), e superiori a quelli ottenibili con pannelli noti di uguale spessore. It has been found that the sound-absorbing panel 10 thus produced has particularly high levels of noise absorption, higher than what it would be logical to expect from a combination of the two basic elements (perforated panel and sheet), and higher than those obtainable with known panels of equal thickness.
