DESCRIZIONE DI INVENZIONE INDUSTRIALE DESCRIPTION OF INDUSTRIAL INVENTION

Avente per titolo: Cerniera elastica a bielle a triplo effetto ed asta così ottenuta, particolarmente per montature di occhiali. Entitled: Triple effect elastic hinge with connecting rods and rod thus obtained, particularly for eyeglass frames.

II presente trovato ha per oggetto una Cerniera elastica a bielle a triplo effetto ed asta così ottenuta, particolarmente per montature di occhiali. The present invention relates to an elastic hinge with triple effect connecting rods and rod thus obtained, particularly for eyeglass frames.

L’innovazione trova particolare se pur non unica applicazione, nel settore dell’ occhialeria. Innovation finds particular, if not the only application, in the eyewear sector.

Detto dispositivo, applicato su ambo i lati dell’occhiale, ha il vantaggio di consentire una maggiore adattabilità della montatura alla anatomia, diversa per ciascuno di noi, del possibile fruitore. Lo stesso richiedente, nell’invenzione industriale n° 01279461 e nelle domande di brevetto per invenzione industriale n° TV95A000039, n° TV96A000163, n° TV97A000177 e n° TV98A000110 propone diverse soluzioni a questo problema. In particolare, nella domanda n° TV98A000110 si affronta la questione della cerniera flessibile in modo molto simile alla presente. La differenza sostanziale è data dalla diversa complessità meccanica dei due dispositivi, in virtù delle curiose situazioni di mercato presenti ai nostri giorni: occhiale “minimalista” con pulizia e semplicità di design (vedi domanda n° TV9SA000110 ), e occhiale “tecnologico” con particolari meccanici complessi (vedi oggetto deila presente). This device, applied on both sides of the glasses, has the advantage of allowing greater adaptability of the frame to the anatomy, different for each of us, of the possible user. The same applicant, in industrial invention no. 01279461 and in patent applications for industrial invention no. TV95A000039, no. TV96A000163, no. TV97A000177 and no. TV98A000110 proposes various solutions to this problem. In particular, in application n ° TV98A000110 the question of the flexible hinge is addressed in a very similar way to the present one. The substantial difference is given by the different mechanical complexity of the two devices, by virtue of the curious market situations present today: "minimalist" glasses with cleanliness and simplicity of design (see question n ° TV9SA000110), and "technological" glasses with details complex mechanics (see object of the present).

Entrando nel merito della domanda di brevetto per invenzione industriale si può procedere alla descrizione della Cerniera elastica a bielle a triplo effetto ed asta così ottenuta, particolarmente per montature di occhiali. Entering into the merits of the patent application for industrial invention, it is possible to proceed with the description of the triple effect elastic hinge with rods and rod thus obtained, particularly for eyeglass frames.

Detto dispositivo è visibile nell’allegata Tav. 1, in condizione di equilibrio stabile in chiusura (Fig.J ), in condizione di equilibrio instabile ( Fig . 2) e in condizione di equilibrio stabile in apertura (Fig. 3). Vi è poi l’allegata Tav. 2, con rappresentata la condizione di funzionamento dinamico (Fig. 1) i particolari di esecuzione nei disegni, la loro forma, le dimensioni, la loro posizione ecc. pur influenzando il funzionamento corretto del meccanismo (essendo tutte intimamente legate fra loro), non sono da ritenersi vincolanti o limitativi ai principi sotto esposti ma puramente descrittivi. This device is visible in the attached Table 1, in a stable equilibrium condition in closing (Fig.J), in an unstable equilibrium condition (Fig. 2) and in a stable equilibrium condition in opening (Fig. 3). Then there is the attached Table 2, with the dynamic operating condition represented (Fig. 1), the execution details in the drawings, their shape, dimensions, position etc. while influencing the correct functioning of the mechanism (as they are all intimately linked to each other), they are not to be considered binding or limiting the principles set out below but purely descriptive.

Ogni astina (M) è composta essenzialmente da: una anima monolitica o composita (D), comprendente, ad una sua estremità, una semicemiera per fissaggio ad una cerniera (B) ricavata in un muso (B): una biella (C) avente alle due estremità due occhielli (C e C”) atti ad essere vincolati non rigidamente (tramite le viti V” e V") rispettivamente al muso (B) nel punto (B ") e al barilotto scorrevole (Af un barilotto scorrevole (A), posto fra due elementi elastici a memoria di forma, costituito essenzialmente da un cilindro metallico avente un foro filettato assiale atto ad alloggiare la vite (V") ed un foro perpendicolare passante atto a garantire, senza giochi eccessivi, lo scorrimento dello stesso lungo l’anima (D): due elementi esastici a memoria di forma nella forma tradizionale per compressione (G ’ e G"), che per comodità chiameremo molle, infilati nell’anima (D), due fermi contenitori delle molle (E‘ e E”) infilati nell’anima (D) e poi bloccati con le opportune lavorazioni meccaniche (brasatura, cianfrinatura, bulinatura ecc. ecc.) un muso (lì) di forma appropriata avente lungo un ramo un alloggiamento per l’unione con il frontale (B") e dall’altro ramo una cerniera (B) atta ad ospitare la semicemiera dell’anima (D) ed un foro filettato (B ”) quale sede per la vite (V”) che vincola l’occhiello (C) della biella (C). Each rod (M) is essentially composed of: a monolithic or composite core (D), comprising, at one end, a half-cup for fixing to a hinge (B) obtained in a muzzle (B): a connecting rod (C) having at the two ends two eyelets (C and C ") suitable for being not rigidly constrained (by means of the screws V" and V ") respectively to the nose (B) at point (B") and to the sliding barrel (Af a sliding barrel (A ), placed between two elastic elements with shape memory, essentially consisting of a metal cylinder having an axial threaded hole able to house the screw (V ") and a perpendicular through hole able to guarantee, without excessive play, the sliding of the same along the core (D): two hexastic shape memory elements in the traditional form by compression (G 'and G "), which for convenience we will call springs, inserted into the core (D), two retainers for the springs (E' and E ") inserted into the core (D) and then blocked with the appropriate mechanical processing ( brazing, crimping, punching etc. etc.) a muzzle (1) of appropriate shape having along one branch a housing for the union with the front (B ") and on the other branch a hinge (B) suitable for housing the half-cup of the core (D) and a threaded hole (B ") as a seat for the screw (V") that holds the eye (C) of the connecting rod (C).

Entrando più in dettaglio nel funzionamento e facendo riferimento anche alle figure diciamo che la condizione di equilibrio stabile in chiusura (asta chiusa) di Tav. 1 - Fig. 1, è data dal contrapporsi delle forze delle due molle (G‘ e G”) che, essendo identiche, spingono con uguale intensità sul barilotto scorrevole (A) mantenendolo stabile in centro fra le due molle stesse. La biella (C) (o le bielle, una sopra e una sotto) vincolata al barilotto (A) tramite la vite (V ”), manterrà la parte (B ”) del muso (B) parallela all’asta stessa. Going into more detail in the operation and also referring to the figures we say that the stable equilibrium condition in closing (closed rod) of Table 1 - Fig. 1, is given by the opposing forces of the two springs (G 'and G ") which, being identical, push with equal intensity on the sliding barrel (A) keeping it stable in the center between the two springs themselves. The connecting rod (C) (or connecting rods, one above and one below) bound to the barrel (A) by means of the screw (V "), will keep the part (B") of the nose (B) parallel to the rod itself.

Da questa condizione di equilibrio stabile in chiusura, il muso (B) (per semplicità descrittiva ruoteremo il muso anziché l’asta) ruotando in senso orario, comprime la molla (G ") (opponendosi al movimento F) tramite la biella (C) fino ad una posizione intermedia di equilibrio instabile (Tav. 1 - Fig. 2), corrispondente alla massima distanza V' - V". Superata questa fase e continuando la rotazione oraria del muso (B) la molla (G ’ ’) tende, estendendosi, ad assumere la condizione primitiva portandosi appresso il muso (B) per mezzo della biella (C). Questa nuova condizione di equilibrio stabile in apertura la possiamo vedere in Tav. 1 - Fig. 3. Il punto (B”) del muso (B) ha compiuto una rotazione di 90°. Mantenendo intatta la conformazione del muso (B) è possibile variare l’angolo suddetto, From this stable equilibrium condition in closing, the nose (B) (for simplicity of description we will rotate the nose instead of the shaft) by rotating clockwise, compresses the spring (G ") (opposing movement F) through the connecting rod (C) up to an intermediate position of unstable equilibrium (Table 1 - Fig. 2), corresponding to the maximum distance V '- V ". After this phase and continuing the clockwise rotation of the nose (B), the spring (G '') tends, extending, to assume the primitive condition, bringing the nose (B) with it by means of the connecting rod (C). This new condition of stable equilibrium in opening can be seen in Table 1 - Fig. 3. The point (B ”) of the nose (B) has made a rotation of 90 °. Keeping the shape of the muzzle intact (B) it is possible to vary the aforementioned angle,

Claims

simply by lengthening or shortening the distance between the points (C and C ") of the connecting rod (C). From the position of Table 1 - Fig. 3, applying a further bending movement (F ") (effective operation of the elastic rod), to the nose (B), there is (through the connecting rod (C)) the compression of the spring ( G) (shorter distance (V '- V "')). Compression will end when the coils of the spring (G) touch. By removing the bending moment (F ") from the nose (B), the spring (G), returning to its original condition, will bring the assembly back into stable equilibrium in opening (Table 1 - Fig. 3).
