PROCEDIMENTO PER REALIZZARE COMPONENTI DI MONTATURE DI OCCHIALI E COMPONENTI REALIZZATI CON TALE PROCEDIMENTO PROCEDURE FOR MAKING COMPONENTS OF GLASSES FRAMES AND COMPONENTS MADE WITH THIS PROCEDURE
DESCRIZIONE DESCRIPTION
Il presente trovato ha per oggetto un procedimento per realizzare componenti di montature di occhiali ed i componenti realizzati con tale procedimento. Ad oggi sono note montature di occhiali realizzate in materiale metallico o in materia plastica, trasparente o colorata. The present invention relates to a method for making components for eyeglass frames and components made with this method. To date, eyeglass frames made of metal or plastic material, transparent or colored, are known.
I componenti della montatura in plastica sono tipicamente prodotti per fresatura o per stampa a iniezione. Plastic frame components are typically produced by milling or injection molding.
Nel procedimento che prevede la fresatura una macchina computerizzata ricava la sagoma del componente da fogli di plastica colorata, più o meno spessi. Di solito i semilavorati così ottenuti sono poi destinati a successive lavorazioni di rifinitura. In the procedure that involves the milling, a computerized machine obtains the shape of the component from sheets of colored plastic, more or less thick. Usually the semi-finished products thus obtained are then destined for subsequent finishing processes.
Con questo procedimento si ricavano varie parti dell'occhiale, ovvero il frontale, le aste e talvolta anche i naselli, che vengono quindi assemblati e rifiniti. With this procedure various parts of the glasses are obtained, namely the front, the temples and sometimes even the nose pads, which are then assembled and finished.
Nel procedimento di produzione che prevede la stampa a iniezione la materia plastica liquefatta viene iniettata nello stampo, riportante l'impronta finale del componente da produrre. In the production process that involves injection molding, the liquefied plastic material is injected into the mold, showing the final impression of the component to be produced.
Entrambi i procedimenti sono molto diffusi e consentono di produrre montature in plastica trasparente o colorata, monocolore o con una varietà limitata di possibili fantasie. Nessuno dei due procedimenti consente infatti di ottenere fantasie come quelle, ad esempio, dei tessuti o delle carte colorate, né un effetto, al tatto o alla vista, simile a quello del tessuto. Both processes are widespread and allow the production of frames in transparent or colored plastic, one-color or with a limited variety of possible patterns. In fact, neither of the two procedures allows to obtain patterns such as those, for example, of fabrics or colored papers, nor an effect, to the touch or sight, similar to that of the fabric.
Il compito del presente trovato à ̈ quello di proporre un procedimento per realizzare componenti di montature di occhiali con particolari effetti di fantasia e materiali, non ottenibili con i procedimenti noti. The object of the present invention is to propose a method for making components for eyeglass frames with particular fancy effects and materials, which cannot be obtained with known methods.
Nell'ambito di tale compito, uno scopo del trovato à ̈ quello di mettere a punto un procedimento mediante il quale realizzare componenti di montature di occhiali strutturalmente resistenti. Questo compito, nonché questo ed altri scopi che meglio appariranno in seguito, sono raggiunti da un procedimento per realizzare componenti di montature di occhiali, caratterizzato dal fatto di comprendere le seguenti fasi: Within the scope of this aim, an object of the invention is to provide a method by which structurally resistant components of spectacle frames are made. This task, as well as this and other purposes which will appear better later, are achieved by a process for making components of eyeglass frames, characterized in that it comprises the following steps:

- la chiusura ed il riscaldamento dello stampo con applicazione e mantenimento della temperatura e della pressione di formatura fino a completa polimerizzazione di detta resina, detto stampo riportando detta impronta sostanzialmente piattiforme, - closing and heating of the mold with application and maintenance of the forming temperature and pressure until the complete polymerization of said resin, said mold bearing said substantially flat impression,
- l'apertura di detto stampo e l'estrazione del manufatto da detto stampo, - opening said mold and extracting the product from said mold,
- il taglio di detto manufatto, a definire detto componente o un suo semilavorato. - the cutting of said manufactured article, to define said component or a semi-finished product thereof.
Ulteriormente formano oggetto del brevetto anche i componenti realizzati secondo tale procedimento, caratterizzati dal fatto di comprendere un frontale o aste di dette montature di occhiali. The patent also includes the components made according to this process, characterized in that they comprise a front or temples of said eyeglass frames.
Ulteriori caratteristiche e vantaggi del trovato risulteranno maggiormente dalla descrizione di una forma di esecuzione preferita, ma non esclusiva, del procedimento e dei componenti secondo il trovato, illustrati, a titolo indicativo e non limitativo, negli uniti disegni, in cui: Further characteristics and advantages of the invention will become clearer from the description of a preferred but not exclusive embodiment of the method and of the components according to the invention, illustrated, by way of non-limiting example, in the accompanying drawings, in which:

Con riferimento alle figure citate, il procedimento secondo il trovato comprende una fase di sovrapposizione sull'impronta 11 di un semistampo 12a, nella seguente successione, di almeno un primo tessuto 13a, almeno un primo strato di fibre di vetro o di carbonio 14a, almeno un tessuto di fibre di vetro o di carbonio 14c, almeno un secondo strato di fibre di vetro o di carbonio 14b ed almeno un secondo tessuto 13b. With reference to the aforementioned figures, the method according to the invention comprises a step of overlapping on the impression 11 of a half-mold 12a, in the following succession, of at least a first fabric 13a, at least a first layer of glass or carbon fibers 14a, at least a glass or carbon fiber fabric 14c, at least a second layer of glass or carbon fibers 14b and at least a second fabric 13b.
Un complementare semistampo 12b, preposto a chiudersi sul semistampo 12a, completa lo stampo 12 illustrato in figura 1. A complementary mold half 12b, designed to close on the mold half 12a, completes the mold 12 illustrated in Figure 1.
In particolare, come risulta evidente dalle figure 1 e 3, la fase di sovrapposizione genera una struttura a sandwich 15 secondo la quale uno strato centrale 16, comprendente il tessuto di fibre di vetro o di carbonio 14c tra il primo ed il secondo strato di fibre di vetro o di carbonio 14a e 14b, Ã ̈ chiuso tra un primo multistrato di tessuto 17a ed un secondo multistrato di tessuto 17b. In particular, as is evident from Figures 1 and 3, the overlapping step generates a sandwich structure 15 according to which a central layer 16, comprising the glass or carbon fiber fabric 14c between the first and the second layer of fibers made of glass or carbon 14a and 14b, it is closed between a first multilayer of fabric 17a and a second multilayer of fabric 17b.
Ciascuno strato di fibre di vetro o di carbonio, primo 14a e secondo 14b, presenta rispettive fibre orientate in un'unica direzione. Each layer of glass or carbon fibers, first 14a and second 14b, has respective fibers oriented in a single direction.
In particolare, nella presente forma realizzativa, qui descritta a titolo esemplificativo e non limitativo del trovato stesso, il primo ed il secondo strato di fibre di vetro o di carbonio 14a e 14b sono disposti con le rispettive fibre orientate secondo la medesima unica direzione. In particular, in the present embodiment, described here by way of non-limiting example of the invention itself, the first and second layers of glass or carbon fibers 14a and 14b are arranged with their respective fibers oriented in the same single direction.
È da intendersi che in altre forme realizzative, per semplicità non illustrate, gli strati di fibre di vetro o di carbonio, primo 14a e secondo 14b, sono disposti con le rispettive fibre unidirezionali orientate secondo direzioni differenti da uno strato all'altro. It is to be understood that in other embodiments, for simplicity not illustrated, the layers of glass or carbon fibers, first 14a and second 14b, are arranged with their respective unidirectional fibers oriented in different directions from one layer to another.
Il primo multistrato di tessuto 17a comprende due strati del primo tessuto 13a ed il secondo multistrato di tessuto 17b comprende due strati del secondo tessuto 13b. The first fabric multilayer 17a comprises two layers of the first fabric 13a and the second fabric multilayer 17b comprises two layers of the second fabric 13b.
Opportunamente, i tessuti 13a e 13b sono impregnati con resina, preferibilmente sintetica, del tipo epossidico o acrilico oppure biologica naturale o bioplastica o alimentare. Conveniently, the fabrics 13a and 13b are impregnated with resin, preferably synthetic, of the epoxy or acrylic type or natural biological or bioplastic or food grade.
Ancora secondo quanto illustrato, questo particolare esempio riportato prevede anche l'impiego di un primo ed un secondo film di materia plastica, rispettivamente 18a e 18b, del tipo poliammidico, o polietilenico o bioplastico. In particolare, la fase di sovrapposizione prevede inizialmente l'applicazione del primo film di materia plastica 18a sull'impronta 11, che viene seguito dagli altri strati sopra elencati, sui quali viene infine sovrapposto il secondo film di materia plastica 18b. Still according to what has been illustrated, this particular example reported also provides for the use of a first and a second film of plastic material, respectively 18a and 18b, of the polyamide, polyethylene or bioplastic type. In particular, the overlapping step initially provides for the application of the first plastic film 18a on the impression 11, which is followed by the other layers listed above, on which the second plastic film 18b is finally superimposed.
In tal modo la struttura a sandwich 15 risulta coperta, in corrispondenza del primo e del secondo multistrato di tessuto 17a e 17b, rispettivamente dal primo e dal secondo film di materia plastica 18a e 18b. In this way, the sandwich structure 15 is covered, in correspondence with the first and second fabric multilayers 17a and 17b, respectively by the first and second plastic film 18a and 18b.
Nella seconda fase del procedimento secondo il trovato lo stampo 12, che riporta un'impronta 11 sostanzialmente piattiforme, viene chiuso e riscaldato, applicando e mantenendo una particolare temperatura ed una particolare pressione di formatura per tutto il tempo in cui esso rimane chiuso, ovvero il tempo necessario affinché la resina migri verso gli altri strati e polimerizzi completamente, incollandoli in tal modo uno all'altro. In the second phase of the method according to the invention, the mold 12, which bears a substantially flat impression 11, is closed and heated, applying and maintaining a particular temperature and a particular forming pressure for the entire time in which it remains closed, i.e. the time required for the resin to migrate to the other layers and cure completely, thus bonding them to each other.
Successivamente lo stampo 12 viene aperto e il manufatto, indicato con 19 in una sua prima forma realizzativa, viene estratto dallo stampo 12. Subsequently, the mold 12 is opened and the product, indicated with 19 in a first embodiment thereof, is extracted from the mold 12.
Infine il manufatto 19 viene tagliato a definire il componente 10. Finally, the article 19 is cut to define the component 10.
La figura 2 illustra il manufatto 19, sul quale à ̈ ritagliata una porzione A il cui ingrandimento riportato in figura 3 ne mette in evidenza le parti sopra descritte. Figure 2 illustrates the article 19, on which a portion A is cut out, the enlargement of which shown in Figure 3 highlights the parts described above.
L’esempio riporta un manufatto 19 dal quale verranno ricavati una serie di frontali di occhiali, su cui non mancheranno pertanto le sedi per le lenti. The example shows an artifact 19 from which a series of spectacle fronts will be obtained, on which there will therefore be no lack of seats for the lenses.
Infatti, come illustrato nelle figure 4 e 5, la fase di taglio prevede sostanzialmente il taglio e l'estrazione dal manufatto 19 delle parti che verranno occupate dalle lenti dell’occhiale e successivamente completa la sagoma del componente. L’impronta 11 dello stampo 12 à ̈ sostanzialmente piattiforme e di sezione sostanzialmente ad U, la quale sezione presenta una gobba centrale 20 che si sviluppa per tutta la lunghezza dell'impronta 11 e genera una sagomatura centrale 21 del profilo del manufatto 19, corrispondente al ponte 22 del componente 10, ovvero il frontale della montatura, destinato all’appoggio sul naso. In fact, as illustrated in figures 4 and 5, the cutting step essentially involves cutting and extracting from the manufactured article 19 the parts that will be occupied by the lenses of the glasses and subsequently completing the shape of the component. The impression 11 of the mold 12 is substantially flat and of a substantially U-shaped section, which section has a central hump 20 which extends along the entire length of the impression 11 and generates a central shaping 21 of the profile of the product 19, corresponding to bridge 22 of component 10, that is the front of the frame, intended for resting on the nose.
Più in particolare, il manufatto 19 comprende vantaggiosamente una porzione centrale 23 dalla quale viene ricavato il frontale della montatura e comprende anche due porzioni laterali 24, corrispondenti alle parti parallele del profilo ad U dell’impronta 11, dalle quali vengono ricavati gli attacchi 25 del frontale per le cerniere con cui assemblare le aste alla montatura. More specifically, the product 19 advantageously comprises a central portion 23 from which the front of the frame is obtained and also includes two side portions 24, corresponding to the parallel parts of the U-shaped profile of the footprint 11, from which the attachments 25 are made. of the front for the hinges with which to assemble the temples to the frame.
Modificando opportunamente la sezione dell’impronta à ̈ possibile ricavare con il medesimo procedimento non solo i frontali ma anche le aste delle montature. By appropriately modifying the footprint section it is possible to obtain with the same procedure not only the fronts but also the temples of the frames.
Come illustrato in figura 6 il componente 10, ovvero il frontale della montatura, comprende due sedi 26, a cornice, per le lenti ed il ponte 22, sagomato secondo la sagomatura centrale 21 del profilo del manufatto 19. As shown in Figure 6, component 10, i.e. the front of the frame, comprises two frame seats 26 for the lenses and the bridge 22, shaped according to the central shape 21 of the profile of the product 19.
In una seconda forma realizzativa del componente secondo il trovato l’impronta à ̈ sprovvista di protuberanza centrale e genera quindi un manufatto 119 privo di sagomatura centrale per il ponte del frontale. In a second embodiment of the component according to the invention, the impression is devoid of a central protuberance and therefore generates an article 119 without a central shape for the front bridge.
È infatti da notare che in base alle esigenze, modificando la forma e le dimensioni dell’impronta ma seguendo il medesimo procedimento, à ̈ possibile ottenere componenti (e quindi frontali) di forma e dimensioni diverse, ad esempio sprovvisti della parte inferiore della cornice delle lenti oppure più o meno larghi secondo le misure previste per la montatura. In fact, it should be noted that according to the needs, by modifying the shape and size of the footprint but following the same procedure, it is possible to obtain components (and therefore fronts) of different shapes and sizes, for example without the lower part of the frame of the lenses or more or less wide according to the measures provided for the frame.
È da notare che il componente potrà essere prodotto con strato centrale 16 in fibre di vetro o in fibre di carbonio, a seconda delle esigenze, e proprio questo strato collabora con i tessuti 13a e 13b nell'assicurare la resistenza strutturale ricercata. It should be noted that the component can be produced with a central layer 16 in glass fibers or carbon fibers, depending on the needs, and this layer collaborates with the fabrics 13a and 13b in ensuring the required structural strength.
Inoltre, come si può constatare dalle figure 1 e 3, gli strati di fibre di vetro o di carbonio 14a e 14b vengono sovrapposti così che le stesse fibre risultino disposte nel componente 10 secondo la direzione della dimensione prevalente, che in questo caso va da un attacco 25 all'altro del frontale. Furthermore, as can be seen from Figures 1 and 3, the layers of glass or carbon fibers 14a and 14b are superimposed so that the same fibers are arranged in component 10 according to the direction of the prevailing size, which in this case goes from one attack 25 to the other of the front.
Questa accortezza assicura maggiore resistenza della montatura all'eventuale piegatura. This foresight ensures greater resistance of the frame to any bending.
È anche da notare che i tessuti 13a e 13b potranno vantaggiosamente essere in lino, in cotone o in altri materiali naturali, che conferiscono al prodotto un aspetto più naturale rispetto ai modelli in commercio. It should also be noted that the fabrics 13a and 13b can advantageously be in linen, cotton or other natural materials, which give the product a more natural appearance than the models on the market.
Inoltre tali tessuti 13a e 13b possono riportare delle particolari fantasie che a produzione ultimata rimangono visibili, essendo ricoperti con un film di materia plastica 18a e 18b sostanzialmente trasparente, oppure quest’ultima potrà essere essa stessa colorata secondo la fantasia ricercata dal produttore. Furthermore, these fabrics 13a and 13b may have particular patterns which remain visible when the production is completed, being covered with a substantially transparent plastic film 18a and 18b, or the latter may itself be colored according to the fantasy sought by the manufacturer.
L'applicazione dei film di materia plastica 18a e 18b conferisce al prodotto un aspetto lucido, ma questi potranno anche non essere impiegati, oppure potranno essere applicati solo da un lato del manufatto, cosicché l'acquirente percepisca anche al tatto l'effetto naturale del tessuto.
