"OBLO PER ELETTRODOMESTICI" "PORTHOLE FOR HOUSEHOLD APPLIANCES"

Il presente trovato riguarda obl? per elettrodomestici . Pi? in particolare il presente trovato riguarda obl? per macchine lavatrici o macchine asciugatrici (Air Dryer) . The present invention relates to obl? for household appliances. Pi? in particular, the present invention relates to obl? for washing machines or drying machines (Air Dryer).

Attualmente gl i obl? per questo tipo di macchine sono costituiti da una calotta in vetro o in plastica trasparente avente forma sostanzialmente emisferica. Currently gl i obl? for this type of machines they consist of a glass or transparent plastic cap having a substantially hemispherical shape.

Al bordo di detta calotta ? di solito applicata una cornice estetica mantenuta in posizione da un'apposita controcornice fissata sul vetro o sul materiale plastico con adesivi o con mezzi di bloccaggio tipo viti . At the edge of that cap? usually applied an aesthetic frame kept in position by a special counter frame fixed on the glass or on the plastic material with adhesives or with locking means such as screws.

Nel la figura 1 ? illustrato, a scopo esemplificativo, una sezione verticale di un obl? secondo la tecnica nota. Al bordo (1 ) della calotta in vetro (2) ? applicata una cornice (3) , avente funzione estetica, ed una controcornice (4) provvista di una sagomatura (5) atta ad accoppiarsi ad una scanalatura (6) presente nella cornice. In Figure 1? illustrated, by way of example, a vertical section of an obl? according to the known art. At the edge (1) of the glass cover (2)? applied a frame (3), having an aesthetic function, and a counterframe (4) provided with a shape (5) able to couple to a groove (6) present in the frame.

Quando la controcornice ? fissata al vetro, con mezzi tipo viti , la sagomatura (4) , impegnata nella scanalatura (5), blocca la cornice mantenendol a fissa nel la posizione desiderata. Al bl occo cornice controcornice ? appl icata la cerniera di collegamento al tel aio dell a macchina e , i n posizione di ametralmente opposta, i l sistema di chiusura/apertura costitui to da un dente a mol la comandato manualmente o elettricamente . When is the counter frame? fixed to the glass by means of screws, the shape (4), engaged in the groove (5), blocks the frame keeping it fixed in the desired position. Al bl occo frame counter frame? Applied the hinge for connection to the frame of the machine and, in the opposite position, the closing / opening system consisting of a tooth to spring operated manually or electrically.

Pertanto , la preparazione degli obl? de lla tecnica nota richi ede moltepl ici operazioni qual i lo stampaggio separato del la cornice e del la controcornice e qui ndi l ' assemblaggio dei due pezzi al l a calotta in vetro. Si tratta , perci?, di operazioni che i ncidono negativamente sul costo dell 'articolo finito. Therefore, the preparation of the obl? of the known art it requires multiple operations such as the separate molding of the frame and the counter frame and here the assembly of the two pieces to the glass cap. Therefore, these are operations that negatively affect the cost of the finished article.

E 1 stato ora trovato dal la Richiedente un obl?, ad esempio per l avatrici o per Ai r Dryer, che non presenta gl i inconvenienti sopra menzionati in quanto ? ottenuto con un procedimento che prevede un'uni ca operazione di stampaggio. The Applicant has now found a window, for example for the washing machines or for the Dryers, which does not have the aforementioned drawbacks in that? obtained with a process which involves a single molding operation.

Costitui sce pertanto oggetto del trovato un obl? per elettrodomestici comprendente una calotta trasparente, avente forma sostanzialmente emi sferica, ed un blocco cornice in pezzo unico in materiale termoplastico applicato a cavallo del bordo periferico di detta ca lotta. Is therefore the object of the invention an obl? for household appliances comprising a transparent cap, having a substantially hemi spherical shape, and a frame block in a single piece of thermoplastic material applied across the peripheral edge of said cap.

I l blocco cornice pu? essere applicato sul bordo con qualsiasi tecnica. Ad esempio si pu? stampare il blocco cornice di -rettamente a cavallo del bordo periferico della calotta oppure si pu? stampare a parte il blocco per appl icarlo sul bordo del -la ca lotta in un successivo momento. In questo secondo caso , per fissare i due pezzi i nsieme si pu? uti l izzare uno qualsiasi dei metodi noti nel l 'arte. Ad esempio i due pezzi possono essere saldati a caldo oppure incol l ati tra loro con opportuni adesivi . The frame block can be applied on the edge with any technique. For example, you can? print the frame block directly over the peripheral edge of the cap or you can? print the block separately to apply it on the edge of the fight at a later time. In this second case, to fix the two pieces together, you can? use any of the methods known in the art. For example, the two pieces can be heat welded or glued together with suitable adhesives.

Secondo il presente trovato l a calotta trasparente ? preferibi lmente i n vetro anche se material i plastici trasparenti , come poi i ca rbo n ato , poi i meti lmet acri 1 ato, resine st i ro lo- acr i -lonitrile, ecc . , possono essere impiegati . According to the present invention, the transparent cap? preferably glass even if it is made of transparent plastic materials, such as carbon, then methyl methyl acrylate, styro-acryl-lonitrile resins, etc. , can be used.

Il bordo periferico del la calotta pu? essere svasato verso l 'esterno e formare con l a stessa superficie esterna un angolo di ci rca D0?. In questo modo il bordo del la calotta si presenta come una corona circol are l a cui altezza di pende dalle dimensioni del l 'obl? oggetto del trovato e quindi dal le dimensioni d e l l e l e t t ro do me st i c o su cui l 'obl? deve essere appl icato. Tuttavia altezze comprese tra 1 e 3 cn sono quel le pi? comunemente u s at e . The peripheral edge of the shell can? be flared towards the outside and form an angle of approximately D0? with the same external surface. In this way, the edge of the cap appears as a circular crown whose height depends on the dimensions of the obl? object of the invention and therefore from the dimensions d e l l e l e t ro do me st i c o on which the obl? must be applied. However, heights between 1 and 3 cn are those the most? commonly u s at e.

Quando il bordo della calotta ? svasato verso l ' esterno il blocco cornice ? applicato a caval lo di detta svasatura. When the edge of the shell? flared outwards the frame block? applied astride said flaring.

Il blocco cornice si presenta con una forma essenzialmente toroidal e dato che si svi luppa su tutta la lunghezza del bordo periferico della calotta trasparente ed ?, preferibi lmente, a sezione verticale cava con spessore del le pareti uniforme e compreso fra 1 e 3 min. The frame block has an essentially toroidal shape and since it develops along the entire length of the peripheral edge of the transparent cap and is preferably a hollow vertical section with a uniform wall thickness between 1 and 3 min.
