Descrizione statica dell'esempio di realizzazione Static description of the example of realization
Con riferimento a tali figure, ed in particolare alla figura 1, con 1 e 2 sono indicate due semisuole materializzate in essenza lignea, la prima destinata a contraffacciare e/o contattare e/o riscontrare la porzione anteriore del piede dell’ utilizzatore, sostanzialmente le dita; la seconda destinata a contraffacciare e/o contattare e/o riscontrare la porzione posteriore del piede dell’utilizzatore, sostanzialmente arcatura e tallone. With reference to these figures, and in particular to figure 1, 1 and 2 indicate two half-soles materialized in wooden essence, the first intended to counter-face and / or contact and / or find the front portion of the user's foot, substantially fingers; the second intended to counterfeit and / or contact and / or detect the rear portion of the user's foot, essentially arch and heel.
Le due semisuole 1 e 2 sono reciprocamente associate gemellate, per adesione e/o annegamento, in una suola di materia plastica 3, preferibilmente elastomerica, che ne ricalca la sagoma in pianta; The two half-soles 1 and 2 are mutually associated twinned, by adhesion and / or drowning, in a sole of plastic material 3, preferably elastomeric, which traces its shape in plan;
in tal quadro le due semisuole 1 e 2 sono preferibilmente accorpate alla suola elastomerica 3 sin dal relativo stadio costitutivo, ovvero in fase di stampaggio di questa, tramite inserimento delle due semisuole 1 e 2 medesime aH’intemo dello stesso stampo entro il quale viene iniettato l’elastomero componente la suola plastica 3. in this framework, the two half-soles 1 and 2 are preferably merged with the elastomeric sole 3 from the relative constitutive stage, or in the molding stage of the latter, by inserting the two half-soles 1 and 2 themselves in the interior of the same mold within which it is injected the elastomer component of the plastic sole 3.
Tra le due semisuole 1 e 2, la suola plastica 3 presenta un ispessimento locale 4, sino a concorrenza del livello superiore delle stesse due semisuole 1 e 2, costituente giunto elastico tra esse, da intendersi indicato con stesso riferimento numerico 4, posizionato in sostanziale corrispondenza dell’articolazione delle falangi dell’ utilizzatore. Between the two half-soles 1 and 2, the plastic sole 3 has a local thickening 4, up to the level of the upper level of the same two half-soles 1 and 2, constituting an elastic joint between them, to be understood as indicated with the same numerical reference 4, positioned substantially correspondence of the articulation of the user's phalanges.
Il giunto elastico 4 si insinua sui due fronti, tramite una pluralità di proprie appendici 5, entro ricettacoli 6 di relativo ritegno praticati sugli spessori contrappostamente prospicienti di dette due semisuole lignee 1 e 2. The elastic joint 4 insinuates itself on the two fronts, through a plurality of its own appendages 5, into receptacles 6 of relative retention made on the opposite facing thicknesses of said two wooden half-soles 1 and 2.
La semisuola lignea posteriore 2 presenta in sostanziale corrispondenza del calcagno dell’ utilizzatore un forame circolare 7, dal quale emerge a livello un complementare risalto circolare 8 della suola plastica 3. The rear wooden half-sole 2 has a circular foramen 7 in substantial correspondence with the user's heel, from which a complementary circular prominence 8 of the plastic sole 3 emerges at level.
Nell’alternativa di realizzazione illustrata nelle figure 3 e 4 la suola plastica 3 presenta una sagoma perimetrale più estesa rispetto alle due semisuole 1 e 2, risolventesi in una cornice 9 che circonda queste tutt’attomo e, preferibilmente, risalta superiormente a livello delle due semisuole 1 e 2 stesse, le quali risultano cosi ivi annegate, per le funzioni che qui di seguito si passano a specificare. In the alternative embodiment illustrated in figures 3 and 4, the plastic sole 3 has a wider perimeter shape than the two half-soles 1 and 2, resolving into a frame 9 that surrounds these all around and, preferably, stands out above the level of the two semisoles 1 and 2 themselves, which are thus drowned therein, for the functions that are specified below.
Descrizione dinamica dell'esempio di realizzazione Avendo così terminato la descrizione statica di un preferito esempio di realizzazione della struttura di suola lignea elasticizzata secondo il presente trovato, come appresso se ne passa infatti ad operare quella dinamica, ovvero il relativo funzionamento: Dynamic description of the example of embodiment Having thus completed the static description of a preferred example of embodiment of the elasticized wooden sole structure according to the present invention, as follows in fact the dynamic one passes to operate, that is the relative operation:
la suola elastica 1 secondo il presente trovato può, ovviamente, esser prodotta in qualsivoglia dimensione ed utilizzata dalPindustria calzaturiera quale una suola secondo la tecnica nota, per assemblarvi qualsiasi tipo e genere di sovrastruttura di ritegno al piede; the elastic sole 1 according to the present invention can obviously be produced in any size and used by the footwear industry as a sole according to the known art, to assemble any type and kind of superstructure for retaining the foot;
altrettanto ovviamente siffatta suola à ̈ però particolarmente adatta a costituire l’elemento portante di calzature aperte e simili, in particolare sandali, e potrà esser corredata di ogni tipo di combinazione di lacci e strisce che servono a tenerli fermi intorno al piede. just as obviously, this sole is however particularly suitable for constituting the load-bearing element of open shoes and the like, in particular sandals, and can be equipped with any type of combination of laces and strips that serve to keep them firm around the foot.
Nell’utilizzo la calzatura ed in particolare il sandalo corredato con la suola elastica 1 secondo il presente trovato, offrirà all’utilizzatore il confort, l’igiene ed il pregio del legno al contatto con il piede, nel contempo ovviando tramite l’inserto elastico 4 alla rigidità che delle suole lignee costituisce lo svantaggio e garantendo salda presa al suolo per Γ interposizione della suola plastica 3. In use, the shoe and in particular the sandal equipped with the elastic sole 1 according to the present invention, will offer the user the comfort, hygiene and value of wood in contact with the foot, at the same time obviating through the € ™ elastic insert 4 to the rigidity of the wooden soles which constitutes the disadvantage and ensuring firm grip on the ground by means of the interposition of the plastic sole 3.
