DESCRIZIONE del Modello Industriale di Utilità' dal titolo: "Dispositivo di protezione e antiscasso, particolarmente per cassette di sicurezza, casseforti e simili" DESCRIPTION of the Industrial Utility Model entitled: "Protection and anti-burglary device, particularly for safety deposit boxes, safes and the like"

TESTO DELLA DESCRIZIONE TEXT OF THE DESCRIPTION

Il presente ^trovato si riferisce alle cassette di sicurezza delle banche, casseforti e simili. The present invention relates to safe deposit boxes for banks, safes and the like.

Attualmente tali cassette, malgrado i sistemi di sicurezza, risultano ancora piuttosto vulnerabili ad azioni di scasso, in quanto le zone critiche rappresentate dalle toppe delle chiavi che dispone il cliente e la banca , potrebbero essere soggette ad introduzione di attrezzi di scasso, ad esempio di grimaldelli, oppure esplosivo o liquidi infiammabili con conseguente possibilità di scasso, Scopo del trovato è quello di ovviare a tale inconveniente prevedendo di proteggere da azioni esterne tali zone critiche delle toppe, intervenendo pertanto sulla parte frontale di dette cassette di sicurezza o simili, al fine di aumentare la protezione contro lo scasso e comunque di aumentare il tempo di scasso stesso necessario per portare a termine l’eventuale rapina, detto trovato evitando laboriosi interventi sulle cassette già esistenti, senza addirittura dover convocare il cliente della cassetta di sicurezza che sì intende proteggere secondo il trovato, evitando altresì operazioni di saldatura, ma limitandosi a semplici fissaggi con viti, prevedendo però il loro completo occultamento allorché il trovato si trova nella configurazione di protezione delle dette toppe, con una soluzione altresì di minimo ingombro. Currently these boxes, despite the security systems, are still quite vulnerable to burglary actions, as the critical areas represented by the key locks that the customer and the bank have, could be subject to the introduction of burglary tools, for example lock picks, or explosive or flammable liquids with consequent possibility of break-in. The purpose of the invention is to obviate this drawback by providing to protect these critical areas of the patches from external actions, thus intervening on the front part of said safety boxes or the like, in order to to increase the protection against burglary and in any case to increase the burglary time necessary to complete the possible robbery, said found avoiding laborious interventions on the already existing boxes, without even having to summon the customer of the safe that is intended to be protected according to the invention, also avoiding welding operations , but limiting itself to simple fastenings with screws, providing however their complete concealment when the invention is in the configuration of protection of said patches, with a solution also of minimum bulk.

Un ulteriore scopo è quello di .costituire una soluzione pratica, semplice, funzionale, affidabile e vantaggiosa, sia come realizzazione e come comodità d’impiego. A further object is to provide a practical, simple, functional, reliable and advantageous solution, both in terms of construction and as a convenience of use.

Questi scopi vengono ottenuti dal trovato prevedendo un dispositivo di protezione e antiscasso, particolarmente per cassette di sicurezza, casseforti e simili, caratterizzato dal fatto di comprendere due piastre quadrilatere, di cui una destinata ad essere fissata, in adatto modo, sulla superficie esterna dello sportello della cassetta di sicurezza o simili e l’altra piastra mobile sulla detta piastra fissa ed in grado di assumere una posizione di chiusura e cioè di protezione andando a sovrapporsi e quindi occultare le toppe per le chiavi di apertura e chiusura- di detta cassetta di sicurezza o simili, per assumere poi un’altra posizione di apertura, previa manovra e consenso dell’operatore, destinata a mettere a vista dette toppe per consentire l’introduzione e l’estrazione delle chiavi dello sportello della cassetta, prevedendo mezzi che consentano di mantenere la piastra mobile nella posizione di apertura per il normale svolgimento delle operazioni di introduzione ed estrazione delle chiavi dalle toppe, nonché mezzi per ripristinare la posizione di chiusura ad operazioni terminate ed altresì mezzi atti ad assicurare il bloccaggio della piastra mobile alla piastra fissa nella posizione di chiusura, assumendo il dispositivo, nella posizione di chiusura, una conformazione antiscasso e cioè consentendo di occultare le zone favorevoli allo scasso rappresentate soprattutto dalle toppe delle chiavi, proprio grazie alla piastra mobile che va invece a sovrapporsi a dette zone, occultandole completamente nella posizione di chiusura, ivi compresi, contemporaneamente anche tutti i mezzi di fissaggio della prima piastra allo sportello della cassetta. These objects are achieved by the invention by providing a protection and anti-burglary device, particularly for safety boxes, safes and the like, characterized in that it comprises two quadrilateral plates, one of which is intended to be fixed, in a suitable way, on the external surface of the door. of the safety box or the like and the other movable plate on said fixed plate and capable of assuming a closing position, i.e. of protection, overlapping and thus hiding the patches for the opening and closing keys of said safety box or similar, to then assume another opening position, subject to maneuver and consent of the operator, intended to show said patches to allow the introduction and extraction of the keys of the box door, providing means that allow to maintain the movable plate in the open position for the normal carrying out of the insertion and extraction operations of the the keys from the patches, as well as means for restoring the closing position when the operations are finished and also means for ensuring the locking of the movable plate to the fixed plate in the closed position, assuming the device, in the closed position, a burglar-proof conformation, i.e. allowing to conceal the areas favorable to break-in represented above all by the key patches, thanks to the movable plate which instead overlaps said areas, hiding them completely in the closed position, including, at the same time, all the means for fixing the first plate to the door of the cassette.

Queste ed altre caratteristiche del trovato ed i vantaggi che ne derivano appariranno evidenti dalla seguente descrizione dettagliata di un preferito esempio esecutivo, non limitativo, con riferimento alle allegate tavole di disegni, in cui: These and other characteristics of the invention and the resulting advantages will become evident from the following detailed description of a preferred, non-limiting example, with reference to the attached drawings, in which:

Con riferimento alle figure il dispositivo secondo il trovato comprende una piastra fissa 10 ed una piastra mobile 11. With reference to the figures, the device according to the invention comprises a fixed plate 10 and a movable plate 11.

La piastra fissa 10 è destinata ad essere applicata alla superficie esterna dello sportello S (fig. 5) della cassetta di sicurezza per l’esempio esecutivo illustrato, oppure casseforti o simili, sfruttando vantaggiosamente i due fori F già esistenti ai lati delle toppe T, detti fori F filettati destinati a ricevere viti, preferibilmente viti 12 di adatta testa svasata e di opportuno diametro, previa foratura della piastra fissa 10 con fori passanti 13 cilindrici, ossia senza svasature, per il solo passaggio dei gambi delle viti 12. Detta testa svasata delle viti 12 di fissaggio della piastra fissa 10, per effetto della sua sottostante conicità risulta opportunamente aggettante ossia sollevata rispetto alla superficie della piastra 10, allorché i gambi di dette viti 12 sono impegnati nei fori F dello sportello 5 e nei fori 13 della piastra 10. The fixed plate 10 is intended to be applied to the external surface of the door S (fig. 5) of the safety box for the illustrated executive example, or safes or the like, advantageously exploiting the two holes F already existing on the sides of the patches T, said threaded holes F intended to receive screws, preferably screws 12 with a suitable countersunk head and suitable diameter, after drilling the fixed plate 10 with cylindrical through holes 13, i.e. without countersinking, for the passage of the screw shanks 12 only. of the fixing screws 12 of the fixed plate 10, due to its underlying conicity it is suitably projecting or raised with respect to the surface of the plate 10, when the stems of said screws 12 are engaged in the holes F of the door 5 and in the holes 13 of the plate 10 .

In detta piastra fissa 10 sono previamente ricavate delle sfinestrature 14 e 15 opportunamente disposte e conformate, in maniera tale che a sovrapposizione avvenuta della piastra fissa 10 sulla superficie esterna dello sportello S (fig. 8), rendano accessibili le toppe T dello sportello S stesso, cosi da consentire l’introduzione delle chiavi per le normali manovre di apertura e chiusura dello sportello S della cassetta di sicurezza. In said fixed plate 10 there are previously formed slots 14 and 15 suitably arranged and shaped, in such a way that once the fixed plate 10 has overlapped on the external surface of the door S (fig. 8), they make the patches T of the door S itself accessible , so as to allow the introduction of the keys for the normal opening and closing operations of the door S of the safety box.

Comunicante con la sfinestratura 14 vi è un’ulteriore sfinestratura 16' di opportuna forma complementare alla sezione trasversale di un cilindro antimanipolazione 17 destinato a passare, con accoppiamento mobile assiale in detta sfinestratura 16. Adiacente alla sfinestratura 16 vi è un’incavatura 18 ricavata sulla faccia esterna della piastra fissa 10 e pressoché a metà altezza di essa. Communicating with the cutout 14 there is a further cutout 16 'of suitable shape complementary to the cross section of an anti-manipulation cylinder 17 intended to pass, with an axial mobile coupling in said cutout 16. Adjacent to the cutout 16 there is a recess 18 obtained on the external face of the fixed plate 10 and almost at half the height thereof.

Sulla faccia esterna della piastra fissa 10 e cioè rivolta verso la piastra mobile 11 è preventivamente applicata una vite 19 a testa svasata aggettante, posizionata superiormente e pressoché centralmente (figg. On the external face of the fixed plate 10, i.e. facing the movable plate 11, a countersunk head screw 19 is previously applied, positioned above and almost centrally (figs.

2 e 5). 2 and 5).

Al disotto dei fori 13 e della sfinestratura 16 è previsto, sulla faccia esterna della piastra fissa 10, un bordo aggettante 20 di lunghezza pari alla larghezza della piastra mobile 11, risvoltante poi ad angolo retto per almeno un certo tratto 201 verso l’alto , detto tratto 201, secondo una forma esecutiva non illustrata, previsto prolungantesi anche per tutta l’altezza della piastra mobile 11 e cioè fino al lato superiore della piastra fissa 10. Below the holes 13 and the cutout 16 there is provided, on the external face of the fixed plate 10, a projecting edge 20 of a length equal to the width of the movable plate 11, then tilts at right angles for at least a certain length 201 upwards, said section 201, according to an embodiment not shown, is foreseen to extend also for the whole height of the movable plate 11, that is to say up to the upper side of the fixed plate 10.

Contro il bordo 20 e tratto 201 è destinata ad .andare a far riscontro la piastra mobile.11 nella posizione di chiusura. Sostanzialmente assialmente rispetto alla sfinestratura 16 è previsto superiormente nella piastra fissa 10 un foro passante 21 a due diametri differenziati di cui quello a diametro maggiore ricavato sulla faccia interna della piastra fissa 10 rivolta verso lo sportello S. Against the edge 20 and the portion 201 it is intended to abut the movable plate 11 in the closed position. Substantially axially with respect to the cutout 16 there is provided at the top in the fixed plate 10 a through hole 21 with two differentiated diameters, of which the one with a larger diameter is obtained on the internal face of the fixed plate 10 facing the door S.

Nella piastra fissa 10 sono previsti poi fori passanti 22 per il passaggio di ulteriori spine di fissaggio allo sportello S e non illustrate. In the fixed plate 10 there are then through holes 22 for the passage of further fastening pins to the door S and not shown.

La piastra mobile 11 è vantaggiosamente destinata a traslare sulla piastra fissa 10, da una posizione di chiusura (fig. 7) (occultamento ed inaccessibilità delle toppe T) sino ad una posizione di apertura (fig. 8) (accessibilità delle toppe T) e viceversa. The movable plate 11 is advantageously intended to translate on the fixed plate 10, from a closed position (fig. 7) (concealment and inaccessibility of the patches T) to an open position (fig. 8) (accessibility of the patches T) and vice versa.

La piastra mobile 11 è traslabile sulla piastra fissa 10, grazie ad almeno una gola a coda di rondine 23 (figg. 4 e 7), chiusa alle due testate e ricavata sulla faccia interna della piastra mobile 11 destinata ad andare a contatto con la piastra fissa 10, in maniera da impedire lo sfilamento della piastra mobile 11 dalla piastra fissa 10, detta gola 23 a coda di rondine (figg, 7 e 9) di adatta sezione e dimensioni, tali da consentire che vada ad impegnarsi, in modo scorrevole, la testa svasata aggettante, analoga a quella delle viti 12 di fissaggio, della suddetta vite 19 (fig. 2), in maniera che la piastra mobile resti vincolata traslabile sulla piastra fissa 10, detta guida 23 il cui asse risulta ortogonale all’asse passante per le due toppe T (fig. 8). The movable plate 11 can be moved on the fixed plate 10, thanks to at least one dovetail groove 23 (figs. 4 and 7), closed to the two heads and obtained on the internal face of the movable plate 11 intended to come into contact with the plate fixed 10, so as to prevent the movable plate 11 from slipping off the fixed plate 10, said dovetail groove 23 (figs, 7 and 9) of suitable section and dimensions, such as to allow it to engage, in a sliding manner, the projecting countersunk head, similar to that of the fixing screws 12, of the aforementioned screw 19 (fig. 2), so that the movable plate remains movable constrained on the fixed plate 10, said guide 23 whose axis is orthogonal to the through axis for the two T patches (fig. 8).

La testa svasata aggettante della vite 19 prevista sulla piastra fissa 10 può andare ad impegnarsi nella gola di guida 23 della piastra mobile 11, grazie ad un foro cieco 24 (figg. 7, 8 e 9) ricavato sulla faccia interna di detta piastra mobile 11, di diametro leggermente superiore a quello della testa svasata aggettante della vite 19 e di profondità pari ad almeno a quello di tale testa aggettante svasata, detto foro 24 comunicante con la gola 23 tramite un breve tratto 25 a coda di rondine ed ortogonale ad essa, in maniera da poter allogare la testa svasata nel foro cieco 24, andando poi detta testa della vite 19 a scorrere nel breve tratto 25 a mezzo di un movimento laterale traslatorio della piastra mobile 11 (figg. 6 7 e 0), sino a poter cosi entrare nella gola 23 di guida cosi da permettere che la piastra mobile 11 possa traslare vincolata sulla piastra fissa in direzione ortogonale all’asse passante per le due toppe T, aumentando contemporaneamente le prestazioni antiscasso del dispositivo per l’ accoppiamento coda di rondine-testa svasata aggettante. The projecting countersunk head of the screw 19 provided on the fixed plate 10 can engage in the guide groove 23 of the movable plate 11, thanks to a blind hole 24 (figs. 7, 8 and 9) obtained on the internal face of said movable plate 11 , with a diameter slightly greater than that of the jutting countersunk head of the screw 19 and with a depth equal to at least that of this jutting countersunk head, said hole 24 communicating with the throat 23 through a short dovetail section 25 and perpendicular to it, so as to be able to accommodate the countersunk head in the blind hole 24, then said head of the screw 19 to slide in the short section 25 by means of a lateral translational movement of the mobile plate 11 (figs. 6, 7 and 0), until it is thus possible enter the guide groove 23 so as to allow the movable plate 11 to translate constrained on the fixed plate in a direction orthogonal to the axis passing through the two patches T, simultaneously increasing the anti-burglary performance of the dovetail-protruding countersunk head coupling device.

Nella piastra mobile 11 sono ulteriormente ricavate, nella faccia interna, due tratti di gola 26 e 27 a coda di rondine, risultanti aperti su una testati e precisamente su quella destinata a far battuta contro il bordo aggettante 20 della piastra fissa 10 e paralleli alla gola 23 di guida principale, disposti lateralmente ad essa, detti tratti di gola 26 e 27 i cui assi coincidono con i centri delle viti a testa svasata 12 di fissaggio della piastra fissa 10 (figg. 4 , 7 e 0), cosi da poter accogliere, detti tratti di gola 26 e 27, le teste svasate aggettanti di tali viti 12, allorché la piastra mobile 11 si trova in posizione di chiusura (fig. 7), in maniera da restare occultate anche le teste svasate di dette viti 12, aumentando ulteriormente le prestazioni antiscasso del dispositivo grazie agli accoppiamenti code di rondine-teste svasate aggettanti ed aumentando le prestazioni antisfilamento della piastra mobile 11 da quella fissa 10. In the mobile plate 11 there are further formed, in the internal face, two portions of the groove 26 and 27 in the shape of a dovetail, resulting open on a head and precisely on the one destined to abut against the projecting edge 20 of the fixed plate 10 and parallel to the groove 23 of main guide, arranged laterally to it, said throat sections 26 and 27 whose axes coincide with the centers of the countersunk head screws 12 for fixing the fixed plate 10 (figs. 4, 7 and 0), so as to be able to accommodate , said throat sections 26 and 27, the protruding countersunk heads of said screws 12, when the movable plate 11 is in the closed position (fig. 7), so as to remain hidden also the countersunk heads of said screws 12, increasing the anti-burglary performance of the device is further enhanced thanks to the dovetail-protruding countersunk heads couplings and by increasing the anti-slip performance of the movable plate 11 from the fixed one 10.

La piastra mobile 11 è mantenuta nella posizione di apertura, grazie a mezzi a scatto consistenti preferibilmente in un perno 28 a molla antagonista 29 (figg. 5 , Il e 12), impegnantesi nel foro 21 andando con la sua testa a far battuta in corrispondenza al diametro minore di detto foro 21, in maniera che detto perno 21 possa automaticamente introdursi in un corrispondente foro passante 30 ricavato nella piastra mobile 11. Tale foro 30, analogamente al foro 21, è previsto a diametri differenziati ed è ricavato a diametro maggiore sulla faccia interna della piastra mobile 11 ed è in grado di accogliere un perno 31 con funzione di pulsantino posizionato in maniera che il suo gambo possa fuoriuscire dalla faccia esterna della piastra mobile 11, mentre la sua testa va a poter far riscontro in corrispondenza al diametro minore interno di tale foro 30. The movable plate 11 is kept in the open position, thanks to snap means preferably consisting of a pin 28 with an antagonist spring 29 (figs. 5, II and 12), engaging in the hole 21 and its head abuts in correspondence to the smaller diameter of said hole 21, so that said pin 21 can automatically insert itself into a corresponding through hole 30 obtained in the movable plate 11. Such hole 30, similarly to hole 21, is provided with different diameters and is obtained with a larger diameter on the inner face of the movable plate 11 and is able to accommodate a pin 31 with the function of a small button positioned so that its stem can protrude from the outer face of the movable plate 11, while its head can be matched in correspondence with the smaller diameter interior of this forum 30.

Ne consegue vantaggiosamente che allorché il detto perno 28 va ad introdursi nel foro 30 della piastra mobile 11, quest'ultima resta cosi vincolata in tale posizione sollevata (posizione di apertura) mettendo in vista ed accessibili le toppe T (figg. 8 e 12), mantenendo in tale posizione la piastra mobile 11 per poter comodamente effettuare le operazioni di introduzione ed estrazioni delle chiavi dalla toppe T per le manovre di apertura e chiusura dello sportello S. It advantageously follows that when said pin 28 enters the hole 30 of the movable plate 11, the latter thus remains constrained in this raised position (opening position), making the patches T visible and accessible (figs. 8 and 12). , keeping the movable plate 11 in this position in order to be able to comfortably carry out the operations of inserting and extracting the keys from the patches T for the opening and closing operations of the door S.

Per disattivare invece i mezzi a scatto che mantengono la piastra mobile 11 nella posizione di apertura basta intervenire sul pulsantino 31, azionabile dall’esterno, in grado di far arretrare il perno di vincolamento 28 fino a disimpegnarlo dal foro 30 della piastra mobile 11, la quale resta cosi svincolata e libera di poter traslare, andando a ripristinare la posizione di chiusura (figg. 7 e 11), fino a poter far battuta contro il bordo aggettante 20 di riscontro della piastra fissa 10. On the other hand, to deactivate the snap means which keep the movable plate 11 in the open position, it is sufficient to act on the push button 31, which can be operated from the outside, which is able to make the locking pin 28 retract until it disengages from the hole 30 of the movable plate 11. which thus remains released and free to be able to move, restoring the closed position (figs. 7 and 11), until it can abut against the jutting edge 20 of abutment of the fixed plate 10.

Sulla faccia esterna della piastra mobile 11 è previsto un blocchetto 32 provvisto di sfinestratura 33 per accogliere, in modo complementare, il cilindro antimanipolazione 17 e ad elevata cifratura, azionabile da chiave esterna, destinato a consentire e ad assicurare l’operazione di bloccaggio della piastra mobile 11 nella posizione di chiusura, nonché lo sbloccaggio di detta piastra mobile 11 da tale posizione di chiusura. On the external face of the movable plate 11 there is a block 32 provided with a cutout 33 to accommodate, in a complementary way, the anti-manipulation and high-coding cylinder 17, operated by an external key, intended to allow and ensure the locking operation of the plate. movable 11 in the closed position, as well as the release of said movable plate 11 from said closed position.

La piastra mobile 11 presenta una sfinestratura 34 coincidente con quella 33 del blocchetto 32 e con quella 1É> della piastra fissa 10, comunque di opportuna forma complementare alla sezione trasversale del cilindro 17 cosi da poterla accogliere con accoppiamento mobile assiale. The movable plate 11 has a cutout 34 coinciding with that 33 of the block 32 and with that 1É> of the fixed plate 10, however of a suitable shape complementary to the cross section of the cylinder 17 so as to be able to accommodate it with an axial movable coupling.

Il detto cilindro 17 è traslabile assialmente (figg. 5, 11, 12 e 14), previa corrispondente manovra di relativa chiave d’azionamento, entro il detto blocchetto 32 e relative sfinestrature 16 e 34 previste sulle piastre rispettivamente 10 fissa e mobile li, in maniera da poter assumere una posizione di bloccaggio andando a traslare fino a raggiungere la sfinestratura 16 della piastra fissa 10 e a penetrare in essa, sino a far riscontro contro la faccia esterna dello sportello S della cassetta ; determinando la posizione di bloccaggio nella posizione di chiusura, mentre è in grado di traslare in direzione opposta, cosi da svincolare la piastra mobile 11 da quella fissa 10 per la traslazione di apertura. Said cylinder 17 can be moved axially (figs. 5, 11, 12 and 14), after corresponding operation of the relative operating key, within said block 32 and relative slots 16 and 34 provided on the fixed and movable plates 10, respectively, in such a way as to be able to assume a locking position by moving until it reaches the cutout 16 of the fixed plate 10 and penetrates into it, until it abuts against the outer face of the door S of the box; determining the locking position in the closed position, while it is able to translate in the opposite direction, so as to release the movable plate 11 from the fixed one 10 for the opening translation.

Adiacente alla sfinestratura 34 della piastra mobile 11 è ricavata una sede incavata 35 pressoché a metà altezza della piastra mobile 11, in maniera che dall’accoppiamento e combinazione con l’incavatura 18 della piastra fissa 10,si ottenga una sede destinata ad accogliere l’elemento a nasello 36 solidale alla rotazione della chiave del cilindro 17 (figg. 13 e 14), dette incavature 18 e 35 di opportuna profondità cosi che l’elemento a nasello 36 possa restare impegnato contemporaneamente nella piastra fissa 10 e nella piastra mobile 11, consentendo nel contempo che il cilindro 17 possa traslare nella sfinestratura 16 della piastra fissa 10 ed assicurare l’ancoraggio antisfilamento del cilindro 17 dalla piastra mobile 11 per il fatto che l’elemento a nasello 36 è poi trattenuto dalla restante paretinà della relativa incavatura 35 della piastra mobile 11, assicurando cosi il bloccaggio della piastra mobile 11 alla piastra fissa 10 nella posizione di chiusura ed assicurando l’antisfilamento del cilindro 17 dalla piastra mobile 11. Per ottenere lo sbloccaggio della piastra mobile 11 dalla piastra fissa 10, per effetto del corrispondente azionamento della chiave del cilindro 17 ne consegue che l’elemento a nasello 36 ruoti sino ad inserirsi a scomparsa nel corpo del cilindro 17, così che quest’ultimo può traslare assialmente verso l’esterno, fuoriuscendo dalla sfinestratura 16, svincolando cosi la piastra mobile 11 dalla piastra fissa 10 per consentire la traslazione di detta piastra 11 sulla piastra 10 . Adjacent to the cutout 34 of the movable plate 11 there is a recessed seat 35 almost halfway up the movable plate 11, so that by coupling and combining with the recess 18 of the fixed plate 10, a seat is obtained which is intended to accommodate the nib element 36 integral with the rotation of the key of the cylinder 17 (figs. 13 and 14), said recesses 18 and 35 of suitable depth so that the nib element 36 can remain engaged simultaneously in the fixed plate 10 and in the movable plate 11, at the same time allowing the cylinder 17 to translate into the opening 16 of the fixed plate 10 and ensuring the anti-slip anchoring of the cylinder 17 from the movable plate 11 due to the fact that the nose element 36 is then held by the remaining wall of the relative recess 35 of the movable plate 11, thus ensuring the locking of the movable plate 11 to the fixed plate 10 in the closed position and of the cylinder 17 from the movable plate 11. To obtain the unlocking of the movable plate 11 from the fixed plate 10, by effect of the corresponding actuation of the key of the cylinder 17 it follows that the nose element 36 rotates until it disappears into the body of the cylinder 17, so that the latter can translate axially outwards, emerging from the cutout 16, thus releasing the movable plate 11 from the fixed plate 10 to allow the translation of said plate 11 onto the plate 10.

Nella posizione di sbloccaggio il cilindro 17 è munito di mezzi antisfilamento dal blocchetto 32 di limitazione della propria traslazione assiale, ad esempio costituiti da un perno filettato 37 di arresto (fig. 12) inserito sulla testata del blocchetto 32 della piastra mobile 11 in grado di impegnarsi in una fresatura 38 prevista ricavata longitudinalmente sul corpo del cilindro 17 (figg. 5 e 12). In the unlocking position, the cylinder 17 is equipped with anti-extraction means from the block 32 limiting its axial translation, for example consisting of a threaded stop pin 37 (fig. 12) inserted on the head of the block 32 of the movable plate 11 capable of engage in a provided milling 38 obtained longitudinally on the body of the cylinder 17 (figs. 5 and 12).

Secondo una forma esecutiva non illustrata, il dispositivo secondo il trovato può essere già previsto in fase di fabbricazione della cassetta di sicurezza, cassaforte o simili, prevedendo in tal caso monopezzo la piastra fissa 10 con il relativo sportello S. According to an embodiment not shown, the device according to the invention can already be provided in the manufacturing phase of the safety deposit box, safe or the like, providing in this case the fixed plate 10 with the relative door S.

Device according to the preceding claims, characterized in that the fixed plate, according to a preferred embodiment, is applied to the door of the safe or the like, advantageously exploiting the two holes already existing on the sides of the patches, said threaded holes intended to receive screws, preferably screws with a suitable countersunk head and suitable diameter, after drilling the fixed plate with cylindrical through holes, ie without countersinking, for the passage of the screw shanks only. 4) - Device according to Claim 3, characterized in that the countersunk head of the fixing screws of the fixed plate, due to its underlying conicity, is suitably projecting or raised with respect to the surface of the fixed plate. 5) - Device according to the preceding claims, characterized by the fact that in the fixed plate there are previously cutouts, suitably arranged and shaped, in such a way that once the fixed plate has overlapped on the external surface of the door, they make the patches of the door itself accessible , so as to allow the introduction of the keys for the normal opening and closing operations of the safety box door. 6) - Device according to the preceding claims, characterized in that the movable plate is intended to translate on the fixed plate, from a closed position (concealment and inaccessibility of the patches) to an open position (accessibility of the patches) and vice versa. 7) - Device according to Claim 6, characterized in that the movable plate can be moved on the fixed plate, thanks to at least one dovetail guide groove, closed to the two heads and obtained on the internal face of the movable plate intended to go to contact with the fixed plate, in such a way as to prevent the movable plate from slipping off the fixed plate, called dovetail groove, of suitable section and dimensions, such as to allow it to engage, in a sliding manner, the protruding countersunk head, analogous to those of the fixing screws, of a member such as screw or similar, previously applied on the fixed plate and on the side facing the movable plate, so that the movable plate remains movable constrained on the fixed plate, said guide whose axis is orthogonal to the axis passing through the two patches. 8) - Device according to Claim 7, characterized in that the countersunk head of the screw provided on the fixed plate can engage in the guide groove of the movable plate thanks to a blind hole obtained on the internal face of said movable plate, of diameter slightly higher than that of the said countersunk head projecting of said screw and with a depth equal to at least the height of said protruding countersunk head, said hole communicating with the groove through a short dovetail section and orthogonal to it, so as to be able to the countersunk head in the blind hole, then said head moving in the short distance by means of a lateral translational movement of the movable plate, until it can thus enter the guide groove so as to allow the movable plate to translate constrained on the fixed plate in direction orthogonal to the axis passing through the two patches, simultaneously increasing the anti-burglary performance of the device for the dovetail-jutting countersunk head coupling. 9) - Device according to the preceding claims, characterized in that in the mobile plate there are further formed, in the internal face, two portions of dovetail grooves, resulting open on a head and parallel to the main guide groove, arranged laterally to it , said groove portions whose axes coincide with the centers of the countersunk head screws for fixing the fixed plate as per claim 4, so as to be able to accommodate, said groove portions, the projecting countersunk heads of said screws, when the movable plate is in the closed position, so that the countersunk heads of said screws are also hidden, further increasing the anti-burglary performance of the device thanks to the dovetail-protruding countersunk heads coupling and increasing the anti-slip performance of the movable plate from the fixed one. 10) - Device according to the preceding claims, characterized in that the movable plate, in the closed position, abuts, at the head, against a projecting edge provided on the external face of the fixed plate, which turns at right angles for at least a certain section on at least one side, possibly for a length equal to that of one side of the movable plate-11) - Device according to the preceding claims, characterized in that the movable plate is kept in the open position, thanks to snap means consisting preferably in a pin and antagonist spring so that said pin can automatically be housed in a corresponding through hole made in the movable plate, thus remaining constrained and maintained, in this position, the movable plate to the fixed plate, showing and accessible the patches for the introduction of the keys. 12) - Device according to Claim 11, characterized in that it is possible to deactivate the snap means which keep the movable plate in the open position, thanks to a small button arranged in said through hole, which can be activated on the external face of the movable plate, able to to move the locking pin back until it disengages from the mobile plate, which thus remains released and free to be able to move, restoring the closed position, until it can abut against the protruding abutment edge. 13) - Device according to the preceding claims, characterized by the fact that on the external face of the movable plate there is a block provided with a cutout to accommodate, in a complementary way, an anti-manipulation and highly encrypted cylinder, which can be activated by an external key by the operator , designed to allow and ensure the locking operation of the movable plate in the closed position, as well as the release of said movable plate from said closed position. 14) - Device according to the preceding claims, characterized in that both the mobile plate and the fixed plate have coincident openings of suitable shape complementary to the cross section of the cylinder so as to be able to accommodate it with an axial mobile coupling. 15) - Device according to the preceding claims, characterized by the fact that the said anti-manipulation cylinder can be axially translated, after a corresponding operation of the relative operating key, within the said block of the movable plate and relative coincident slots provided on the plates, respectively movable and fixed , in such a way as to be able to assume a locking position by moving until it reaches the cutout of the fixed plate and penetrates into it until it abuts against the external face of the door of the safe deposit box or the like, determining the locking position in the position of closing, while it is able to translate in the opposite direction, so as to release the movable plate from the fixed one for the opening translation. 16) - Device according to Claim 15, characterized by the fact that in the locking position, the nib element integral with the rotation of the key of the anti-manipulation cylinder is provided that it can be inserted into a special recessed seat obtained almost at half height respectively of the fixed plate and of the movable plate and adjacent to the slot for insertion of the anti-manipulation cylinder, so that this seat thus composed of the coupling and the combination of said recesses can accommodate the nib element, said recesses of suitable depth so that the 'nose element can remain engaged simultaneously in the fixed plate and in the movable plate, at the same time allowing the anti-manipulation cylinder to translate in the opening of the fixed plate and ensure the anti-slip anchorage of the cylinder from the movable plate due to the fact that the element a nosepiece is then retained by the restan the wall of the relative recess of the movable plate itself, thus ensuring the locking of the movable plate to the fixed plate in the closed position and ensuring the anti-extraction of the cylinder from the movable plate. 17) - Device according to the preceding claims, characterized by the fact that in the unlocking position the cylinder is equipped with means that prevent the block from slipping off its axial translation, for example consisting of a stop pin inserted on the head of the block of the movable plate, capable of engaging in a foreseen milling obtained longitudinally on the cylinder body. 18) -
