“DISPOSITIVO DI APERTURA, PARTICOLARMENTE PER CASSETTE ED ARMADIETTI DI CONTENIMENTO PER APPARECCHIATURE ANTINCENDIO E/O ANTINFORTUNI-STICHE” "OPENING DEVICE, PARTICULARLY FOR BOXES AND CONTAINMENT CABINETS FOR FIRE AND / OR ACCIDENT PREVENTION EQUIPMENT"

D E S C R I Z I O N E DESCRIPTION

Il presente trovato ha per oggetto un dispositivo di apertura, particolarmente per cassette, armadietti e in genere di vani richiudibili di contenimento per apparecchiature antincendio e/o antinfortunistiche, quali, ad esempio, estintori, manichette per acqua, dispositivi di protezione, kit di pronto soccorso. The present invention relates to an opening device, particularly for boxes, cabinets and in general for reclosable containment compartments for fire and / or accident prevention equipment, such as, for example, fire extinguishers, water hoses, protection devices, ready kits rescue.

Oggigiorno sono in uso cassette ed armadietti dotati di uno sportellino apribile e richiudibile mediante una maniglia o una leva. Cassettes and cabinets equipped with a door that can be opened and closed by means of a handle or lever are in use today.

Le vigenti normative antincendio prevedono l’utilizzo di dispositivi di chiusura muniti di sigillo di sicurezza oppure di una serratura con dispositivo di apertura di emergenza protetto da materiale frangibile e trasparente. Current fire regulations provide for the use of closing devices equipped with a safety seal or a lock with an emergency opening device protected by breakable and transparent material.

In tal modo, l’accesso al vano, che deve avvenire solamente in casi di necessità o di emergenza, è sempre segnalato dalla rottura del sigillo o del vetro frangibile. In this way, access to the compartment, which must take place only in cases of necessity or emergency, is always signaled by the breakage of the seal or the breakable glass.

In tal modo vengono inoltre rese evidenti eventuali manomissioni o furti alle apparecchiature contenute nella cassetta o nell’ armadietto. In this way, any tampering or theft of the equipment contained in the box or locker is also made evident.

Sono noti dispositivi di apertura costituiti da una serratura apribile mediante una chiave alloggiata in un vano chiuso ma visibile; tale vano può essere ad esempio ricavato nello sportello della cassetta, ed è usualmente chiuso mediante un vetro frangibile e trasparente, in modo da consentire, all’ evenienza, la rottura del vetro, la il prelievo della chiave ivi contenuta e la successiva apertura della serratura e quindi dello sportello stesso. Opening devices are known consisting of a lock that can be opened by means of a key housed in a closed but visible compartment; this compartment can be obtained, for example, in the door of the box, and is usually closed by means of a breakable and transparent glass, so as to allow, if necessary, the glass to break, the removal of the key contained therein and the subsequent opening of the lock and therefore of the door itself.

Altri dispositivi di apertura di tipo noto comprendono ad esempio un sigillo, quale un elemento filiforme chiuso, opportunamente associato alla cassetta e allo sportello in modo da impedire la apertura di quest’ultimo. Other known type opening devices include, for example, a seal, such as a closed filiform element, suitably associated with the box and the door in order to prevent the latter from opening.

In questo caso l’utilizzatore potrà avere accesso al vano solamente dopo aver compiuto la rottura del sigillo stesso. In this case, the user will be able to access the compartment only after having broken the seal itself.

Il principale svantaggio di tali dispositivi di apertura di tipo noto consiste nel fatto di non risultare pratici e veloci nellutilizzo, soprattutto anche considerando le situazioni di urgenza nelle quali attivati. The main disadvantage of these known opening devices consists in the fact that they are not practical and quick to use, especially also considering the urgent situations in which they are activated.

Un altro inconveniente che i tipi noti presentano riguarda il fatto che risulta spesso difficile o complesso il ripristino dei sigilli, siano essi costituiti da un vetro frangibile, da un elemento filiforme o da altro. Another drawback that the known types have concerns the fact that it is often difficult or complex to restore the seals, whether they consist of a breakable glass, a thread-like element or other.

Un ulteriore svantaggio che deriva da questo inconveniente riguarda il fatto che tali dispositivi di apertura sono dotati di sigilli anche molto differenti l’uno dall’altro, questo provocando difficoltà nella ricerca di ricambi. A further disadvantage that derives from this drawback concerns the fact that these opening devices are equipped with seals that are also very different from each other, this causing difficulties in the search for spare parts.

Un altro importante svantaggio dei tipi noti consiste nel fatto di presentare un impatto estetico spesso poco gradevole. Another important disadvantage of the known types consists in the fact that they have an often not very pleasant aesthetic impact.

Ancora un inconveniente presentato da molti dispositivi di apertura di tipo noto è dato dal fatto che essi risultano poco intuitivi ed immediati nell’utilizzo. Another drawback presented by many known type opening devices is the fact that they are not very intuitive and immediate in use.

Altri armadietti antincendio e antinfortunistica di tipo noto prevedono l’utilizzo di lastre in materiale plastico frangibile e trasparente, con le quali proteggere l’accesso al vano. Other known fire and accident prevention cabinets provide for the use of sheets of breakable and transparent plastic material, with which to protect access to the compartment.

Di conseguenza l utilizzatore, in caso di necessità, deve frangere la lastra prima di accedere al materiale contenuto all’interno dell’ armadietto. Consequently, the user, if necessary, must break the slab before accessing the material contained inside the cabinet.

Oltre a presentare alcuni degli inconvenienti sopra citati, questi dispositivi di tipo noto risultano molto costosi, in quanto dopo l’apertura dell’ armadietto è necessario sostituire l’intera lastra. In addition to presenting some of the aforementioned drawbacks, these known devices are very expensive, as after opening the cabinet it is necessary to replace the entire plate.

Per di più tali lastre, realizzate in particolari materiali e con particolari specifiche tecniche di lavorazione, in modo da non essere pericolosi per l’utilizzatore, presentano un costo unitario alquanto elevato. Moreover, these plates, made of particular materials and with particular specific processing techniques, so as not to be dangerous for the user, have a rather high unit cost.

Compito principale di quanto forma oggetto del presente trovato è quindi quello di risolvere i problemi tecnici evidenziati, eliminando gli inconvenienti di cui alla tecnica nota citata e quindi escogitando un trovato il quale consenta di ottenere un dispositivo di apertura che sia semplice e pratico da utilizzare, risultando nel contempo robusto e gradevole nell’aspetto. The main aim of the subject matter of the present invention is therefore to solve the technical problems highlighted, eliminating the drawbacks of the cited known art and therefore devising an invention which allows to obtain an opening device which is simple and practical to use, resulting at the same time robust and pleasant in appearance.

Nell’ambito del compito sopra esposto, un altro importante scopo è quello di realizzare un trovato che permetta di effettuare il ricambio del sigillo, dopo Γ apertura, in modo semplice ed economico. Within the scope of the aforementioned task, another important object is to provide an invention that allows the replacement of the seal, after opening, in a simple and economical way.

Ancora un importante scopo è quello di realizzare un trovato che consenta all’utilizzatore l’uso di differenti tipologie di sigillo, a seconda delle necessità, senza alcun cambiamento strutturale nel dispositivo di apertura. Another important object is to provide an invention that allows the user to use different types of seals, as needed, without any structural change in the opening device.

Uno scopo ulteriore consiste nel realizzare un trovato che sia intuitivo e rapido da utilizzare. A further object is to provide an invention which is intuitive and quick to use.

Non ultimo scopo è quello di realizzare un trovato che risulti strutturalmente semplice, il medesimo presentando costi realizzativi contenuti. Not least object is to provide an invention which is structurally simple, the same having contained manufacturing costs.

Il compito e gli scopi accennati, nonché altri che più chiaramente appariranno in seguito, vengono raggiunti da un dispositivo di apertura, particolarmente per cassette ed armadietti dotati di almeno uno sportellino girevole di accesso ad uno o più vani interni, che si caratterizza per il fatto che detto almeno uno sportellino comprende una maniglia girevole presentante primi mezzi di serraggio temporaneo di detto sportellino, e secondi mezzi di presa per la rotazione parziale di detta maniglia stessa, a consentire la apertura di detto sportellino e la simultanea rottura di terzi mezzi di segnalazione della avvenuta apertura di detta cassetta o armadietto. The aforementioned aim and objects, as well as others which will appear more clearly below, are achieved by an opening device, particularly for boxes and cabinets equipped with at least one revolving door for access to one or more internal compartments, which is characterized by the fact that said at least one door comprises a revolving handle having first means for temporarily locking said door, and second gripping means for the partial rotation of said handle itself, to allow the opening of said door and the simultaneous breaking of third means for signaling the opening of said box or cabinet.

Ulteriori carateristiche e vantaggi del trovato risulteranno maggiormente dalla descrizione dettagliata di una particolare forma di realizzazione, illustrata a titolo indicativo e non limitativo nelle tavole di disegni allegate, in cui: Further characteristics and advantages of the invention will become clearer from the detailed description of a particular embodiment, illustrated by way of non-limiting example in the attached drawings, in which:

Con riferimento alle figure precedentemente citate, si è indicato con il numero 1 un dispositivo di apertura, particolarmente utilizzabile per cassete ed armadietti di contenimento per apparecchiature antincendio e/o antinfortunistiche. With reference to the aforementioned figures, the number 1 indicates an opening device, particularly usable for drawers and containment cabinets for fire and / or accident prevention equipment.

In figura 8 è illustrato a titolo di esempio un armadieto, indicato con il numero 2, costituito da un corpo scatolare cavo 3 richiudibile mediante uno sportellino 4 girevolmente associato a detto corpo scatolare 3 mediante una coppia di cardini, indicati con il numero 5. Figure 8 illustrates by way of example a cupboard, indicated with the number 2, consisting of a hollow box-like body 3 that can be closed by means of a door 4 rotatably associated with said box-like body 3 by means of a pair of hinges, indicated with the number 5.

Il dispositivo di apertura 1 risulta associato allo sportellino 4, di accesso ad uno o più vani interni, circa in prossimità di un primo bordo, indicato con il numero 6, opposto alla coppia di cardini 5. The opening device 1 is associated with the door 4, for accessing one or more internal compartments, approximately in proximity to a first edge, indicated with the number 6, opposite the pair of hinges 5.

Tale dispositivo di apertura 1 comprende un telaio 7, di forma approssimativamente anulare, associabile entro una controsagomata prima sede, non illustrata, ricavata in detto sportellino 4. Said opening device 1 comprises a frame 7, of approximately annular shape, which can be associated within a counter-shaped first seat, not shown, obtained in said door 4.

Il telaio 7 è costituito da una cassa 8 dotata di almeno una coppia di alette laterali, indicate con il numero 9, aventi sezione trasversale circa triangolare e sporgenti da parti opposte ad una distanza tra loro di poco maggiore al diametro di detta prima sede. The frame 7 consists of a case 8 equipped with at least one pair of lateral fins, indicated with the number 9, having an approximately triangular cross section and protruding from opposite sides at a distance slightly greater than the diameter of said first seat.

Detta almeno una coppia di alette 9 sono parzialmente elasticamente deformabili, in modo da consentire linserimento della cassa 8 in detta prima sede dello sportellino 4, a conseguire il successivo bloccaggio della medesima. Said at least one pair of fins 9 are partially elastically deformable, so as to allow the casing 8 to be inserted into said first seat of the door 4, to achieve subsequent locking thereof.

Tale cassa 8 presenta una corona perimetrale 10 sporgente frontalmente a posizionarsi esternamente allo sportellino 4, avente in pianta forma approssimativamente circolare e lateralmente aperta in corrispondenza di una prima zona, indicata con il numero 11 . Said case 8 has a perimeter crown 10 projecting frontally to position itself externally to the door 4, having an approximately circular shape and laterally open in correspondence with a first area, indicated with the number 11.

La cassa 8 e la corona 10 definiscono una prima apertura centrale, indicata con il numero 12, entro cui si posiziona una maniglia 13 costituita da una base piana 14, controsagomata a detta prima apertura 12, dalla quale sporge circa perpendicolarmente e posteriormente un gambo 15, di forma vantaggiosamente parallelepipeda. The case 8 and the crown 10 define a first central opening, indicated by the number 12, within which a handle 13 is positioned consisting of a flat base 14, counter-shaped to said first opening 12, from which a stem 15 protrudes approximately perpendicularly and posteriorly. , advantageously parallelepiped in shape.

Ad una prima estremità libera 16 di detto gambo 15 è associata o resa solidale una ala arcuata, indicata con il numero 17, sporgente circa perpendicolarmente e rivolta verso la prima zona aperta 11. An arched wing, indicated by the number 17, projecting approximately perpendicularly and facing the first open area 11, is associated or made integral with a first free end 16 of said shank 15.

Da parte opposta rispetto alla ala arcuata 17 sono opportunamente ricavati dei primi mezzi di serraggio temporaneo di detto sportellino 4, preferibilmente costituiti da un dente, indicato con il numero 18, sporgente circa perpendicolarmente da detta prima estremità libera 16 del gambo 15. On the opposite side with respect to the arched wing 17, first means for temporary clamping of said door 4 are suitably formed, preferably consisting of a tooth, indicated with the number 18, protruding approximately perpendicularly from said first free end 16 of the shank 15.

Tale dente 18 è atto ad impegnarsi temporaneamente con una superficie di battuta 19 ricavata internamente ad un secondo bordo perimetrale, indicato con il numero 20, di detto corpo scatolare cavo 3. Said tooth 18 is able to temporarily engage with an abutment surface 19 obtained inside a second perimeter edge, indicated with the number 20, of said hollow box-like body 3.

Trasversalmente a detto gambo 15, da parte opposta al dente 18, è ottenuto un perno 21 le cui estremità sono associate alla cassa 8 del telaio 7, così da costituire un elemento di fulcraggio per la rotazione parziale della maniglia 13 rispetto al telaio 7. Transversely to said shank 15, on the side opposite to the tooth 18, a pin 21 is obtained, the ends of which are associated with the case 8 of the frame 7, so as to constitute a pivot element for the partial rotation of the handle 13 with respect to the frame 7.

Il perno 21, allocato quindi in posizione contrapposta rispetto alla prima zona aperta 11 della corona 10, è vantaggiosamente passante entro una coppia di feritoie 22, ricavate in detta cassa 8. The pin 21, therefore located in an opposite position with respect to the first open area 11 of the crown 10, is advantageously passing through a pair of slots 22, obtained in said casing 8.

In tal modo, la maniglia 13 può essere fatta ruotare parzialmente attorno al perno 21, vantaggiosamente mediante la presenza di secondi mezzi di presa, in questa particolare forma realizzativa costituiti ad esempio da una seconda apertura, indicata con il numero 23, ricavata nella base piana 14 della maniglia 13 da parte opposta rispetto al perno 2 1. In this way, the handle 13 can be partially rotated around the pin 21, advantageously by means of the presence of second gripping means, in this particular embodiment consisting for example of a second opening, indicated with the number 23, obtained in the flat base 14 of the handle 13 on the opposite side with respect to the pin 2 1.

Tale seconda apertura 23 presenta dimensioni sufficienti a consentire il passaggio di almeno un dito, indicato nelle figure 11, 12 e 13 con il numero 24, dellutilizzatore, così da consentire a quest’ultimo di ruotare la maniglia 13 attorno al perno 21 fino a disaccoppiare il dente 18 dalla superficie di battuta 19 (come illustrato nelle figure 12 e 13). This second opening 23 has sufficient dimensions to allow the passage of at least one finger, indicated in figures 11, 12 and 13 with the number 24, of the user, so as to allow the latter to rotate the handle 13 around the pin 21 until it is uncoupled. the tooth 18 from the abutment surface 19 (as illustrated in Figures 12 and 13).

La maniglia 13 è preferibilmente dotata di almeno un elemento elasticamente deformabile, precaricabile durante la rotazione della maniglia 13 stessa, atto a consentire il suo ritorno in posizione originaria dopo il rilascio da parte dellutilizzatore. The handle 13 is preferably provided with at least one elastically deformable element, which can be preloaded during the rotation of the handle 13 itself, able to allow it to return to its original position after release by the user.

In particolare, tale elemento elasticamente deformabile è vantaggiosamente costituito da detta ala arcuata 17, la quale presenta una seconda estremità libera 25 che va a contatto su di un piano di scorrimento 26 solidale o associato trasversalmente a detta cassa 8, circa in prossimità della prima zona aperta 11, da parte opposta alla corona perimetrale 10. In particular, this elastically deformable element is advantageously constituted by said arched wing 17, which has a second free end 25 which comes into contact with a sliding plane 26 integral with or associated transversely to said box 8, approximately in proximity to the first area open 11, on the opposite side to the perimeter crown 10.

Ad una rotazione della maniglia 13 consegue una deformazione elastica della ala arcuata 17, la cui curvatura tende a ridursi; nel contempo si ha la forzata traslazione della seconda estremità 25 lungo il piano di scorrimento 26, fino a raggiungere una condizione di equilibrio tra la forza esercitata dallutilizzatore sulla maniglia e la forza elastica sviluppata dalla ala 17 deformata. A rotation of the handle 13 results in an elastic deformation of the arched wing 17, the curvature of which tends to be reduced; at the same time there is the forced translation of the second end 25 along the sliding plane 26, until a condition of equilibrium is reached between the force exerted by the user on the handle and the elastic force developed by the deformed wing 17.

Una ulteriore trazione sulla maniglia 13 impone la apertura dello sportellino 4 (vedi fig. 13), possibile in quanto viene a mancare la interposizione di parti tra il dente 18 e la superficie di battuta 19. A further traction on the handle 13 forces the opening of the door 4 (see fig. 13), possible since there is no interposition of parts between the tooth 18 and the abutment surface 19.

Il dispositivo di apertura 1 prevede anche lutilizzo di terzi mezzi di segnalazione della avvenuta apertura dell’ armadietto 2. The opening device 1 also provides for the use of third means of signaling the successful opening of the locker 2.

Tali, terzi mezzi possono essere ad esempio costituiti da un sigillo filiforme, indicato nella figura 9 con il numero 50, posto tra la maniglia 13 ed il telaio 7. Such third means can for example consist of a thread-like seal, indicated in figure 9 with the number 50, placed between the handle 13 and the frame 7.

In questa forma realizzativa, in prossimità della seconda apertura 23 della maniglia 13 sporge esternamente una prima appendice, indicata con il numero 27, avente una forma vantaggiosamente controsagomata alla prima zona aperta 11 della corona perimetrale 10. In this embodiment, near the second opening 23 of the handle 13 protrudes externally a first appendage, indicated with the number 27, having a shape advantageously counter-shaped to the first open area 11 of the perimeter ring 10.

A maniglia 13 posta in posizione non ruotata, la prima appendice 27 è atta a dispomi circa esattamente tra le pareti laterali 28a e 28b della prima zona aperta 11 della corona perimetrale 10. With the handle 13 placed in the non-rotated position, the first appendix 27 is adapted to be arranged approximately exactly between the side walls 28a and 28b of the first open area 11 of the perimeter ring 10.

Tali prima appendice 27 e pareti laterali 28a e 28b presentano un primo, un secondo ed un terzo foro 29a, 29b e 29c passanti, adiacenti tra loro ed ottenuti lungo il medesimo asse, il quale è disposto circa parallelamente al perno 2 1. Said first appendix 27 and side walls 28a and 28b have a first, second and third hole 29a, 29b and 29c which pass through, adjacent to each other and obtained along the same axis, which is arranged approximately parallel to the pin 2 1.

Lungo detti primo, secondo e terzo foro 29a, 29b e 29c è posizionabile il sigillo filiforme 50, in modo che ad una prima rotazione della maniglia 13 corrisponda la contemporanea rottura del sigillo medesimo. The thread-like seal 50 can be positioned along said first, second and third holes 29a, 29b and 29c, so that a first rotation of the handle 13 corresponds to the simultaneous breaking of the seal itself.

In alternativa od in aggiunta a tale sigillo filiforme 50 può essere impiegata una serratura costituita da un cilindro, non illustrato, posizionabile entro una sede costituita da una terza apertura 30, cilindrica, ricavata in detta base piana 14 di fianco alla seconda apertura 23 . Alternatively or in addition to this thread-like seal 50, a lock consisting of a cylinder, not illustrated, can be used which can be positioned within a seat consisting of a third cylindrical opening 30 formed in said flat base 14 next to the second opening 23.

Tale cilindro è atto ad interagire selettivamente con detto piano di scorrimento 26, solidale o associato trasversalmente alla cassa 8, consentendo o meno la apertura dello sportellino 4. Said cylinder is able to selectively interact with said sliding plane 26, integral with or associated transversely to the casing 8, allowing or not the opening of the flap 4.

L’attivazione del cilindro avviene mediante una chiave 31 opportunamente posta all’interno di un primo vano, indicato con il numero 32, associato inferiormente a detto telaio 7. The cylinder is activated by means of a key 31 suitably placed inside a first compartment, indicated with the number 32, associated below said frame 7.

La interconnessione tra il primo vano 32 ed il telaio 7 avviene mediante il posizionamento di una coppia di seconde appendici 33, entro controsagomate seconde sedi, indicate con il numero 34, ricavate inferiormente al telaio 7 stesso in corrispondenza della corona perimetrale 10. The interconnection between the first compartment 32 and the frame 7 takes place through the positioning of a pair of second appendages 33, inside counter-shaped second seats, indicated with the number 34, obtained below the frame 7 itself in correspondence with the perimeter ring 10.

Tali seconde appendici 33, di forma preferibilmente arcuata verso Γ esterno, presentano delle zone di cedimento costituite ad esempio da un intaglio 35, ricavato in prossimità della zona di interconnessione a detto primo vano 32. Said second appendages 33, preferably of a shape arched towards the outside, have areas of yielding constituted for example by a notch 35, obtained in proximity of the area of interconnection to said first compartment 32.

La chiave 31 è alloggiata internamente al primo vano 32, nella intercapedine 36 presente tra il medesimo e la superficie anteriore dello sportellino 4; tale intercapedine 36 è lateralmente chiusa per mezzo di un terzo bordo perimetrale, indicato con il numero 37, presente in detto primo vano 32. The key 31 is housed inside the first compartment 32, in the interspace 36 present between it and the front surface of the door 4; this interspace 36 is closed laterally by means of a third perimeter edge, indicated with the number 37, present in said first compartment 32.

In questa particolare forma realizzativa la chiave 31, disposta verticalmente, poggia vantaggiosamente su di una coppia di supporti, indicati con il numero 38, costituiti da due lamelle verticali, parallele tra loro, sporgenti internamente a detta intercapedine 36. In this particular embodiment, the key 31, arranged vertically, advantageously rests on a pair of supports, indicated with the number 38, consisting of two vertical blades, parallel to each other, protruding internally to said interspace 36.

L’utilizzatore, agendo su di una terza appendice 39, sporgente da detto primo vano 32 da parte opposta rispetto alle seconde appendici 33, potrà imporre una rotazione del medesimo attorno ai punti di interconnessione al telaio 7, in modo da provocare il conseguente cedimento della coppia di seconde appendici 33 in corrispondenza degli intagli 35. The user, acting on a third appendix 39, protruding from said first compartment 32 on the opposite side with respect to the second appendages 33, can impose a rotation thereof around the points of interconnection to the frame 7, so as to cause the consequent yielding of the pair of second appendages 33 in correspondence with the notches 35.

Una volta separato il primo vano 32 dal telaio 7, sarà possibile accedere alla chiave 31 e con essa agire sulla serratura in modo da aprire lo sportellino 4. Once the first compartment 32 has been separated from the frame 7, it will be possible to access the key 31 and with it act on the lock in order to open the flap 4.

In alternativa all’impiego del primo vano 32 sopra descritto, è possibile utilizzare un secondo vano, illustrato in fig. 8, di tipo noto in quanto costituito da una terza sede 41, usualmente di forma cilindrica, ricavata in detto sportellino 4. As an alternative to the use of the first compartment 32 described above, it is possible to use a second compartment, illustrated in fig. 8, of known type since it consists of a third seat 41, usually cylindrical in shape, obtained in said door 4.

Tale terza sede 41 è atta ad alloggiare la chiave 31, ed è anteriormente chiusa da una lastrina 42, realizzata in materiale plastico frangibile, la quale funge da sigillo, dovendo essere infranta per consentire l’accesso alla chiave 31 stessa. This third seat 41 is suitable for housing the key 31, and is closed at the front by a plate 42, made of breakable plastic material, which acts as a seal, having to be broken to allow access to the key 31 itself.

Nel caso non si utilizzi la serratura né il primo od il secondo vano, la terza apertura 30 per Γ alloggiamento del cilindro della serratura può essere vantaggiosamente chiusa mediante l’utilizzo di un controsagomato tappo, indicato in figura 2 con il numero 43 . If neither the lock nor the first or second compartment are used, the third opening 30 for housing the lock cylinder can be advantageously closed by using a counter-shaped cap, indicated in figure 2 with the number 43.

Il funzionamento è quindi il seguente: con riferimento alle figure dalla 11 alla 13, si nota come l utilizzatore, in caso di necessità, possa conseguire la apertura dello sportellino 4 in modo estremamente rapido ed intuitivo, semplicemente ruotando la maniglia 13 e tirandola a se. The operation is therefore as follows: with reference to figures 11 to 13, it can be seen that the user, in case of need, can open the flap 4 extremely quickly and intuitively, simply by rotating the handle 13 and pulling it to himself. .

Durante la prima rotazione della maniglia, la appendice 27 si allontana dalle pareti laterali 28a e 28b della corona perimetrale 10, provocando la repentina rottura del sigillo filiforme 50, preventivamente posto lungo il primo, il secondo ed il terzo foro 29a, 29b e 29c. During the first rotation of the handle, the appendix 27 moves away from the side walls 28a and 28b of the perimeter crown 10, causing the sudden breaking of the thread-like seal 50, previously placed along the first, second and third holes 29a, 29b and 29c.

La presenza della ala arcuata 17, precaricata durante la attivazione della maniglia 13, consente, dopo il rilascio dell’utilizzatore, il ritorno della medesima entro la prima apertura 12 del telaio 7. The presence of the arched wing 17, preloaded during the activation of the handle 13, allows, after the release of the user, the return of the same within the first opening 12 of the frame 7.

Nel caso in cui si preferisca utilizzare una serratura ed una chiave 31 posta entro un primo vano 32, le operazioni da eseguire per aprire larmadietto 2 consistono nel tirare la terza appendice 39 fino a provocare la rottura della coppia di seconde appendici 33, aventi la finizione di sigillo, e quindi costituenti terzi mezzi di segnalazione della apertura di detta cassetta o armadietto. If it is preferred to use a lock and a key 31 placed inside a first compartment 32, the operations to be carried out to open the cabinet 2 consist in pulling the third appendix 39 until the pair of second appendages 33, having the finish of seal, and therefore constituting third means for signaling the opening of said box or cabinet.

Una volta rimosso il primo vano 32, si può prelevare la chiave 31 e quindi conseguire la apertura della serratura e quindi dello sportellino 4. Once the first compartment 32 has been removed, the key 31 can be removed and the lock and therefore the flap 4 can be opened.

Si è così constatato come il trovato abbia raggiunto il compito e gli scopi prefissati, essendosi escogitato un dispositivo di apertura alquanto semplice e pratico da utilizzare.
