Description

Titolo: "Pannelli per uso esterno" Title: "Panels for external use"

TESTO DELLA. DESCRIZIONE TEXT OF. DESCRIPTION

Il presente trovato concerne un pannello per uso esterno, in particolare per l'uso in balconi e recinzioni o staccionate in montagna. The present invention relates to a panel for external use, in particular for use in balconies and fences or fences in the mountains.

E' noto da anni l'uso di stecche di legno per l'uso in esterno in tali applicazioni per molteplici ragioni tra cui il notevole risultato estetico. Malgrado guesto uso continuativo da anni del legno, esso richiede una continua manutenzione e ormai da anni si cerca di diminuirne l'uso per problematiche ambientali. Una valida alternativa sul mercato sono i prodotti in materia plastica. In particolare è noto l'uso del PVC rigido o PVC espanso o PVC riciclato che hanno sostituto i pannelli in legno benché a differenza di questi si siano dimostrati non solo esteticamente notevolmente inferiori, ma anche più fragili. Per ovviare a questi inconvenienti sono stati progettati pannelli multistrato. Per esempio nel documento JP 10180776 viene descritta una struttura multistrato, avente un nucleo di materiale interno di PVC e almeno uno strato poliuretanico in grado di migliorare l'estetica e le proprietà di resistenza alle intemperie di un tavolato. The use of wooden slats for outdoor use in such applications has been known for years for many reasons including the remarkable aesthetic result. Despite this continuous use of wood for years, it requires continuous maintenance and for years we have been trying to reduce its use due to environmental problems. A viable alternative on the market are plastic products. In particular, it is known the use of rigid PVC or expanded PVC or recycled PVC which have replaced wooden panels although unlike these they have proved not only aesthetically considerably inferior, but also more fragile. To overcome these drawbacks, multilayer panels have been designed. For example in the document JP 10180776 a multilayer structure is described, having a core of internal PVC material and at least one polyurethane layer capable of improving the aesthetics and weather resistance properties of a plank.

Nel documento MI-,2000U000024 della stessa richiedente viene descritto un pannello multistrato, nel quale un nucleo interno di PVC viene rivestito su tutti i lati da una struttura bistrato comprendente un ulteriore strato di PVC di spessore di circa 150μm e uno strato di polimetilmetacrilato di circa 50μm. Questi pannelli se da una costituiscono una valida alternativa ai prodotti legnosi, essi si sono dimostrati poco adatti per l'ottenimento di pannelli con differenti sagomature tipiche di strutture abitative di montagna . In document MI-, 2000U000024 of the same applicant, a multilayer panel is described, in which an inner core of PVC is coated on all sides by a two-layer structure comprising a further layer of PVC with a thickness of about 150μm and a layer of polymethylmethacrylate of approximately 50μm. While these panels constitute a valid alternative to wood products, they have proved unsuitable for obtaining panels with different shapes typical of mountain living structures.

Scopo della presente invenzione è pertanto fornire un pannello per uso esterno sagomabile che sia esteticamente gradevole e che pertanto assomigli ai pannelli di legno, ma non presenti i suoi inconvenienti. The object of the present invention is therefore to provide a shapeable panel for external use that is aesthetically pleasing and therefore resembles wooden panels, but does not have its drawbacks.

La presente invenzione ha brillantemente risolto questo problema prevedendo un pannello multistrato con adatte dimensioni degli strati stessi che può quindi essere sagomato risultando esteticamente simile ad un prodotto di legno sagomato e non con separazione di colori o ancora distacco o deformazione seppur parziale dello strato più esterno del pannello. The present invention has brilliantly solved this problem by providing a multilayer panel with suitable dimensions of the layers themselves which can therefore be shaped, resulting aesthetically similar to a shaped wood product and not with color separation or even detachment or deformation, even if partial, of the outermost layer of the panel.

Tale scopo è raggiunto da una pannello come alla rivendicazione 1, alla quale si rimanda per brevità. This object is achieved by a panel as in claim 1, to which reference is made for the sake of brevity.

Il presente trovato viene qui di seguito dettagliatamente descritto, a titolo esemplificativo e non limitativo, con riferimento agli allegati disegni, nei quali: The present invention is described in detail below, by way of non-limiting example, with reference to the attached drawings, in which:

la Figura 1 è una vista frontale di un pannello sagomato secondo il trovato; Figure 1 is a front view of a shaped panel according to the invention;

la Figura 2 è una vista in sezione del pannello della Figura 1; Figure 2 is a sectional view of the panel of Figure 1;

La figura 3 è una vista frontale del pannello prima della sagomatura; Figure 3 is a front view of the panel before shaping;

Il pannello secondo il presente trovato, mostrato in figura 1, è indicato globalmente con il riferimento numerico 10 e presenta un nucleo interno 12 e uno strato esterno 14. The panel according to the present invention, shown in Figure 1, is globally indicated with the reference number 10 and has an internal core 12 and an external layer 14.

11 nucleo interno 10 è PVC, preferibilmente PVC espanso. Può essere anche impiegato PVC riciclato, il quale però richiede una verniciatura totale a causa del effetto multicolore proprio del PVC riciclato. The inner core 10 is PVC, preferably expanded PVC. Recycled PVC can also be used, which however requires a total painting due to the multicolored effect of recycled PVC.

Secondo la presente invenzione lo spessore del detto nucleo interno di PVC è tra circa 15 mm a 30 mm, preferibilmente 20 mm. Questo intervallo di spessore è essenziale al fine di procedere di un ottenere un pannello sagomato. Infatti al di sopra di 30mm i costi del PVC sono così alti da rendere non economica la produzione di tali pannelli e quindi la sostituzione con essi del prodotto legnoso, mentre al di sotto di 15 mm il nucleo di PVC è troppo flessibile. Il detto strato 14 è una pellicola di polimetilmetacrilato che permette protezione verso gli agenti atmosferici e che risulta inalterabile nei colori per almeno 10 anni. Essa è già prestampata con la caratteristica venatura del legno e quindi quando applicata sul nucleo interno 12 forma un pannello rassomigliante ad un pannello di legno. Al fine di permettere la sagomatura del pezzo senza dare origine a difetti esterni visivi di distacco, lo spessore dello strato 14 deve essere al massimo 0,2 mm. According to the present invention, the thickness of the said internal PVC core is between about 15 mm and 30 mm, preferably 20 mm. This range of thickness is essential in order to proceed to obtain a shaped panel. In fact, above 30mm the costs of PVC are so high as to make the production of these panels and therefore the replacement of the wood product with them uneconomical, while below 15 mm the PVC core is too flexible. Said layer 14 is a polymethylmethacrylate film which allows protection against atmospheric agents and which is unalterable in colors for at least 10 years. It is already pre-printed with the characteristic wood grain and therefore when applied to the inner core 12 it forms a panel resembling a wooden panel. In order to allow the shaping of the piece without giving rise to external visual defects of detachment, the thickness of the layer 14 must be a maximum of 0.2 mm.

L'applicazione di detta pellicola avviene attraverso metodi noti quali per esempio mediante pellicolatrice a rulli su un nucleo di PVC ottenuto mediante estrusione a caldo. The application of said film takes place by known methods such as for example by means of a roller film-forming machine on a PVC core obtained by means of hot extrusion.

La struttura di strati di dimensione definita secondo il trovato permette l'ottenimento di pannelli per uso esterno, particolarmente per recinzioni e balconi, che si presentano esteticamente come i pannelli di legno, sono facilmente sagomabili, ma rispetto a questi resistono alle intemperie e non necessitano di manutenzione continua. The structure of layers of defined size according to the invention allows to obtain panels for external use, particularly for fences and balconies, which appear aesthetically like wooden panels, are easily shaped, but with respect to these they are resistant to bad weather and do not require of continuous maintenance.

Il presente trovato è infine suscettibile di numerose modifiche e varianti, tutte rientranti nel concetto innovativo espresso nelle rivendicazioni allegate, mentre i dettagli tecnici potranno variare a seconda delle esigenze. The present invention is finally susceptible of numerous modifications and variations, all falling within the innovative concept expressed in the attached claims, while the technical details may vary according to requirements.
