DESCRIZIONE DESCRIPTION
annessa alla domanda di brevetto per Invenzione Industriale dal titolo: attached to the patent application for Industrial Invention entitled:
“Soletta monoblocco per calzature”, "Monobloc insole for footwear",
Il presente trovato concerne una soletta monoblocco per calzature ed il relativo procedimento di realizzazione. The present invention relates to a monobloc insole for footwear and the related manufacturing process.
Le tecniche note per realizzare questo tipo di accessori per calzature comprendono tradizionalmente più fasi, che generalmente prevedono la preparazione di una soletta a dima in materiale cellulosico o naturale, di un cartone fibrato di spessore compreso tra 2 e 4 millimetri, di una lamina metallica adeguata alla forma. The known techniques for making this type of accessories for footwear traditionally comprise several steps, which generally involve the preparation of a template insole in cellulosic or natural material, of a fiber cardboard with a thickness of between 2 and 4 millimeters, of a suitable metal sheet. to form.
Innanzitutto, la lamina viene rivettata al cartone che poi viene incollato alla soletta; questo semilavorato viene poi introdotto in uno stampo per acquisire la curvatura desiderata, e successivamente fresato per eliminare gli eccessi di cartone. Sono note anche soluzioni realizzative, come descritto nella domanda di brevetto MC2010A000042, in cui la lamina può essere annegata in un materiale polimerico termoplastico, quale, ad esempio l’ABS. First of all, the foil is riveted to the cardboard which is then glued to the insole; this semi-finished product is then introduced into a mold to acquire the desired curvature, and subsequently milled to eliminate excess cardboard. Implementation solutions are also known, as described in patent application MC2010A000042, in which the sheet can be embedded in a thermoplastic polymeric material, such as, for example, ABS.
In molti casi, specie per calzature femminili con tacco, alla parte anteriore della soletta deve essere associato un rialzo, gergalmente definito “plateau”: in tali circostanze, la soletta viene fornita ad un altro artigiano che progetta un plateau ad essa compatibile per poi procedere all’associazione tra plateau e soletta ed alla loro rifinitura manuale. In many cases, especially for women's shoes with heels, the front part of the insole must be associated with a rise, jargonally defined as a "plateau": in such circumstances, the insole is supplied to another craftsman who designs a compatible platform to then proceed to the association between plateau and insole and their manual finishing.
Altri prodotti, anche diversamente definiti, utilizzano parte della lavorazione sopra descritta, ma, in presenza di plateau, necessitano tutti di realizzare in momenti distinti soletta e plateau, provocando diversi ineliminabili svantaggi. Other products, even differently defined, use part of the processing described above, but, in the presence of plateaus, they all need to realize the slab and plateau at different times, causing various unavoidable disadvantages.
Innanzitutto, per ogni modello e per ogni numero, sono necessari due coppie di stampi: una per il plateau ed una per la porzione posteriore della soletta. Infatti, gli stampi utilizzati definiscono sia la forma che la curvatura del prodotto finale. First of all, for each model and for each number, two pairs of molds are required: one for the plateau and one for the rear portion of the insole. In fact, the molds used define both the shape and the curvature of the final product.
Inoltre, la presenza di una giunzione di due prodotti diversi comporta che la successiva fase di fasciatura in pelle, o altro materiale, nel tempo provochi una segnatura decisamente antiestetica. Furthermore, the presence of a junction of two different products means that the subsequent wrapping phase in leather, or other material, over time causes a decidedly unsightly signature.
Infine, il prodotto finito presenta un peso notevole a causa dell’elevata quantità di ABS, o di altro materiale termoplastico, utilizzato. Finally, the finished product has a considerable weight due to the high amount of ABS, or other thermoplastic material, used.
Lo scopo del presente trovato è pertanto quello di eliminare gli inconvenienti sopra menzionati. The object of the present invention is therefore to eliminate the aforementioned drawbacks.
Il trovato, quale esso è caratterizzato dalle rivendicazioni, raggiunge lo scopo realizzando una soletta in una sola fase operativa. The invention, as it is characterized by the claims, achieves the object by providing an insole in a single operating step.
Il principale vantaggio ottenuto mediante il presente trovato consiste essenzialmente nel fatto che, per ogni modello e per ogni numero, è sufficiente una sola coppia di stampi: infatti, la forma finale è determinata dallo stampo in cui viene inserita la lamina metallica provvista di un proprio rivestimento. The main advantage obtained by means of the present invention essentially consists in the fact that, for each model and for each number, only one pair of molds is sufficient: in fact, the final shape is determined by the mold in which the metal sheet is inserted, provided with its own coating.
Inoltre, la realizzazione in un unico pezzo evita automaticamente la presenza di giunzioni di materiali diversi, e di conseguenza qualsiasi possibile inestetismo dovuto alla fasciatura esterna. Furthermore, the construction in one piece automatically avoids the presence of joints of different materials, and consequently any possible imperfection due to the external bandage.
Infine, la soletta e la calzatura risultano notevolmente più leggere, a parità di volume, sia per il ridotto impiego di polimeri termoplastici, quali l’ABS, sia per l’uso di un polimero termoindurente assai leggero. Finally, the insole and the shoe are considerably lighter, for the same volume, both due to the reduced use of thermoplastic polymers, such as ABS, and to the use of a very light thermosetting polymer.
Ulteriori vantaggi e caratteristiche del trovato saranno maggiormente evidenti nella descrizione dettagliata che segue, fatta con riferimento ai disegni allegati, che ne rappresentano un esempio non limitativo di esecuzione, in cui: Further advantages and characteristics of the invention will be more evident in the detailed description that follows, made with reference to the attached drawings, which represent a non-limiting example of execution, in which:
- la figura 1 illustra il trovato secondo una vista laterale; Figure 1 illustrates the invention according to a side view;
- la figura 2 illustra il trovato secondo una vista prospettica dall’alto; - Figure 2 illustrates the invention according to a perspective view from above;
- la figura 3 illustra il trovato secondo una vista dall’alto, con alcune parti asportate per meglio evidenziarne altre; - Figure 3 illustrates the invention according to a top view, with some parts removed to better highlight others;
- la figura 4 illustra dei particolari del trovato; Figure 4 illustrates details of the invention;
- la figura 5 illustra i particolari di cui in figura 4 assemblati per l’uso. - Figure 5 illustrates the details referred to in Figure 4 assembled for use.
Come si può osservare dalle figure, il presente trovato concerne una soletta monoblocco per calzature comprendente una porzione anteriore (11) in materiale omogeneo semirigido, preferibilmente un polimero termoindurente, ed una porzione posteriore (12) non omogenea, all’interno della quale è annegato un elemento (13) di irrigidimento, atto a conferire a detta porzione posteriore (12) la curvatura desiderata. Nel procedimento di realizzazione, ottenuto per colatura di materiale semirigido in un unico stampo, è sufficiente che la curvatura della porzione posteriore (12) sia compatibile con quella dello stampo. As can be seen from the figures, the present invention relates to a monobloc insole for footwear comprising a front portion (11) made of homogeneous semi-rigid material, preferably a thermosetting polymer, and a non-homogeneous rear portion (12), inside which it is embedded a stiffening element (13), able to give said rear portion (12) the desired curvature. In the manufacturing process, obtained by pouring semi-rigid material into a single mold, it is sufficient that the curvature of the rear portion (12) is compatible with that of the mold.
L’elemento (13) di irrigidimento comprende una lamina (14) metallica curva ed un rivestimento (15), preferibilmente realizzato con un polimero termoplastico, atto ad avvolgere la lamina (14). The stiffening element (13) comprises a curved metal sheet (14) and a coating (15), preferably made with a thermoplastic polymer, suitable for wrapping the sheet (14).
Specie nel caso di scarpe con tacco, la porzione anteriore (11) comprende una base (16) spessorata, spesso definita “plateau”. Per assicurare un maggior comfort all’utente, è vantaggioso che la soletta (10) comprenda una sede (17) superficiale, atta ad alloggiare un rivestimento anti-urto. Especially in the case of shoes with heels, the front portion (11) includes a thickened base (16), often referred to as a “plateau”. To ensure greater comfort for the user, it is advantageous for the insole (10) to include a surface seat (17), suitable for housing an anti-impact coating.
Tra i molti materiali che possono essere utilizzati nella realizzazione delle solette (10) in questione, una combinazione ottimale si ottiene se la porzione anteriore (11) è realizzata in poliuretano ed il rivestimento (15) è realizzato in ABS. Among the many materials that can be used in making the insoles (10) in question, an optimal combination is obtained if the front portion (11) is made of polyurethane and the covering (15) is made of ABS.
Il procedimento di realizzazione di questo tipo di soletta (10) monoblocco per calzature, comprende almeno le seguenti fasi: The manufacturing process of this type of monobloc insole (10) for footwear comprises at least the following steps:
- preparazione di un elemento (13) di irrigidimento comprendente una lamina (14) metallica curva ed un rivestimento (15) in materiale rigido, atto ad avvolgere la lamina (14); - preparation of a stiffening element (13) comprising a curved metal sheet (14) and a coating (15) made of rigid material, suitable for wrapping the sheet (14);
- colatura di un materiale semirigido in uno stampo contenente l’elemento (13) di irrigidimento. - casting of a semi-rigid material into a mold containing the stiffening element (13).
In generale, il materiale rigido è un polimero termoplastico, quale l’ABS, mentre il materiale semirigido è un polimero termoindurente, quale il poliuretano. In general, the rigid material is a thermoplastic polymer, such as ABS, while the semi-rigid material is a thermosetting polymer, such as polyurethane.
Il trovato così concepito è suscettibile di numerose modifiche e varianti, tutte rientranti neN’ambito del concetto inventivo. Inoltre, tutti i dettagli possono essere sostituiti da elementi tecnicamente equivalenti. The invention thus conceived is susceptible of numerous modifications and variations, all falling within the scope of the inventive concept. Furthermore, all the details can be replaced by technically equivalent elements.
Nella pratica sono ovviamente possibili delle modifiche e/o delle migliorie rientranti comunque neN’ambito delle seguenti rivendicazioni. In practice, modifications and / or improvements are obviously possible, however, falling within the scope of the following claims.
