Description
Descrizione dell’invenzione industriale dal titolo: GIUNTO A SNODO A SPAZIO VARIABILE PER DOGHE METALLICHE DI SERRANDE AVVOLGIBILI; Description of the industrial invention entitled: VARIABLE SPACE JOINT FOR METALLIC SLATS OF ROLLING SHUTTERS;
La presente invenzione concerne il settore delle serrande metalliche avvolgibili costituite da una pluralità di doghe reciprocamente vincolate a quelle adiacenti per la realizzazione di un manto di persiana, per chiudere in sicurezza aperture d’accesso ad ambienti e luci di edifici civili e industriali. The present invention relates to the sector of metal rolling shutters consisting of a plurality of slats mutually constrained to the adjacent ones for the construction of a shutter, to safely close access openings to environments and lights of civil and industrial buildings.
Le serrande avvolgibili attualmente note sono costituite da una pluralità di doghe, ciascuna delle quali (a parte le due doghe di estremità) è vincolata alla doga che la precede e a quella che la segue in modo articolato, per consentire l’avvolgimentosvolgimento di detta serranda al rullo di raccolta della serranda stessa. Currently known rolling shutters consist of a plurality of staves, each of which (apart from the two end staves) is linked to the stave that precedes it and to the one that follows it in an articulated way, to allow the winding-up of said shutter to the collection roller of the shutter itself.
E’ noto che quando piove, specialmente se piove a vento, purtroppo l’acqua piovana trafila tra una doga e quelle adiacenti delle attuali serrande in quanto: It is known that when it rains, especially if it rains in the wind, unfortunately the rainwater seeps between a plank and the adjacent ones of the current shutters because:
- in configurazione di totale chiusura, le doghe sono semplicemente appoggiate tra loro; - in a completely closed configuration, the slats are simply placed against each other;
- in configurazione di sollevamento, le doghe risultano scostate da quelle adiacenti lasciando un piccolo spazio, che peraltro può essere utile quando si vuole arieggiare l’ambiente senza però aprire la serranda. - in the lifting configuration, the slats are separated from the adjacent ones, leaving a small space, which can also be useful when you want to ventilate the environment without opening the shutter.
Un altro svantaggio delle serrande attualmente note, è relativo al fatto che è possibile sollevare il manto semplicemente afferrando la doga inferiore e applicando una forza verso l’alto in modo da traslare l’intero manto, fino ad ottenere un varco che consente di accedere all’interno della serranda stessa. Per evitare questo inconveniente, solitamente si cerca di bloccare lateralmente una o più doghe, nel tentativo di impedirne il sollevamento indesiderato, ad esempio con dei piccoli catenacci laterali. Another disadvantage of currently known shutters relates to the fact that it is possible to lift the curtain simply by grasping the lower stave and applying an upward force in order to translate the entire curtain, until a passage is obtained which allows access to the inside the damper itself. To avoid this inconvenience, an attempt is usually made to block one or more slats laterally, in an attempt to prevent unwanted lifting, for example with small side bolts.
Scopo principale della presente invenzione è, quindi, quello di superare i suddetti svantaggi della tecnica nota. The main object of the present invention is therefore to overcome the aforementioned disadvantages of the known art.
Un altro scopo della presente invenzione è quello di realizzare una serranda avvolgibile in cui le doghe, in configurazione di chiusura, si dispongano a guisa di persiana, in modo che - in caso di pioggia - non ci siano infiltrazioni di acqua sul lato interno della serranda. Another purpose of the present invention is to realize a rolling shutter in which the slats, in the closed configuration, are arranged in the manner of a shutter, so that - in case of rain - there are no water infiltrations on the internal side of the shutter. .
Un ulteriore scopo del trovato è di fornire una serranda in cui ciascuna doga, in caso di sollevamento del manto dal basso verso l’alto, si disponga in modo da contrastare il movimento di scorrimento verso l’alto cooperando con le guide laterali presenti alle estremità delle doghe stesse. A further object of the invention is to provide a shutter in which each slat, in case of lifting of the curtain from the bottom upwards, is arranged in such a way as to oppose the upward sliding movement by cooperating with the lateral guides present at the ends. of the staves themselves.
Questi ed altri scopi sono stati raggiunti dalla presente invenzione, fornendo un giunto snodato a luce variabile per doghe metalliche configurato in modo tale che, durante il sollevamento dall’alto del manto avvolgibile, le doghe risultano sostanzialmente allineate su uno stesso piano e distanziate tra loro, mentre al termine dell’abbassamento per la chiusura del manto, le doghe risultano inclinate e parzialmente sovrapposte in modo simile alle tegole di un tetto, così che in caso di pioggia, l’acqua scorra sul lato esterno del manto senza poter passare all’interno. These and other purposes have been achieved by the present invention, providing an articulated joint with variable span for metal slats configured in such a way that, during the lifting from above of the rolling shutter, the slats are substantially aligned on the same plane and spaced apart from each other. , while at the end of the lowering to close the mantle, the slats are inclined and partially overlapped in a similar way to the tiles of a roof, so that in case of rain, the water flows on the external side of the mantle without being able to pass to the internal.
Ciò è stato ottenuto, secondo il trovato, prevedendo un giunto a snodo, fissabile ad ognuna delle due estremità di ciascuna doga e collegabile alla doga adiacente, in cui ciascun giunto è dotato di una piastrina oscillante vincolabile - in modo parzialmente scorrevole ed oscillante - al corrispondente giunto a snodo della doga adiacente, ed in cui è presente un nottolino che mantiene detta piastrina di poco inclinata rispetto al corpo del giunto stesso. In tal modo, quando le doghe sono distaccate, la loro distanza massima è determinata dalla piastrina oscillante, mentre quando le doghe sono accostate, l’inclinazione della piastrina aumenta per far ruotare parzialmente una doga rispetto a quella adiacente. This has been achieved, according to the invention, by providing an articulated joint, which can be fixed to each of the two ends of each slat and can be connected to the adjacent slat, in which each joint is equipped with an oscillating plate that can be fixed - in a partially sliding and oscillating way - to the corresponding articulated joint of the adjacent slat, and in which there is a pawl which keeps said plate slightly inclined with respect to the body of the joint itself. In this way, when the slats are detached, their maximum distance is determined by the oscillating plate, while when the slats are side by side, the inclination of the plate increases to partially rotate a slat with respect to the adjacent one.
Nella presente descrizione, i termini “serranda avvolgibile” e “manto avvolgibile” sono utilizzati come sinonimi per indicare l’insieme delle doghe che costituiscono, appunto, la serranda o il manto. In this description, the terms "roller shutter" and "roller shutter" are used interchangeably to indicate the set of slats that make up the shutter or curtain.
Una migliore comprensione dell’invenzione si avrà con la seguente descrizione dettagliata e con riferimento ai disegni allegati che illustrano, a puro titolo esemplificativo e non già limitativo, una preferita forma realizzativa. A better understanding of the invention will be obtained with the following detailed description and with reference to the attached drawings which illustrate, purely by way of example and not limiting, a preferred embodiment.
Nei disegni: In the drawings:
la figura 1 è una vista esplosa di un giunto a snodo laterale a luce variabile secondo la presente invenzione, nella quale sono mostrate le parti principali; Figure 1 is an exploded view of a variable span lateral joint according to the present invention, in which the main parts are shown;
le figure 2, 3 e 4 , corrispondenti alla fig. 1, mostrano le modalità di assemblaggio del giunto prima di fissarlo all’estremità di una doga; figures 2, 3 and 4, corresponding to fig. 1, show how to assemble the joint before fixing it to the end of a plank;
la figura 5, mostra in sequenza 3D le modalità di fissaggio del corpo del giunto all’estremità di una doga, mediante dei perni laterali disposti longitudinalmente alla doga stessa; Figure 5, shows in 3D sequence the methods of fixing the joint body at the end of a plank, by means of lateral pins arranged longitudinally to the plank itself;
la figura 6 mostra, in una vista parziale, alcune doghe disposte in configurazione di sollevamento, mentre sono distanziate tra loro; figure 6 shows, in a partial view, some slats arranged in a lifting configuration, while they are spaced apart;
la figura 7, analoga alla precedente, mostra alcune doghe disposte in configurazione di chiusura, mentre sono accostate tra loro e inclinate a guisa di persiana o di tegole di un tetto. Figure 7, similar to the previous one, shows some staves arranged in a closed configuration, while they are placed side by side and inclined like a shutter or roof tiles.
Con riferimento alle figure sopra descritte, il giunto snodato G a luce variabile, fissabile a ciascuna estremità di doghe metalliche D comprende: With reference to the figures described above, the articulated joint G with variable span, which can be fixed to each end of metal slats D comprises:
- un corpo 1 di forma sostanzialmente parallelepipeda, in cui due spigoli corti 7 contrapposti lungo una diagonale sono smussati, il quale corpo 1 è configurato per essere fissato all’estremità di una doga D; - a body 1 of substantially parallelepiped shape, in which two short edges 7 opposite each other along a diagonal are beveled, which body 1 is configured to be fixed to the end of a stave D;
- una piastrina laterale 2 a sviluppo longitudinale, dotata di un foro 5A per il suo fissaggio al corpo 1 - sul lato opposto a quello della doga D - mediante una vite V avvitabile in almeno un apposito foro filettato laterale interno 5 del corpo 1 stesso; detta piastrina laterale 2 è configurata per essere vincolata girevolmente al corpo 1 inserito in una prima doga D e girevolmente e scorrevolmente al corpo 1 inserito in una seconda doga D adiacente alla prima. - a lateral plate 2 with longitudinal development, equipped with a hole 5A for its fixing to the body 1 - on the side opposite to that of the stave D - by means of a screw V which can be screwed into at least one specific internal lateral threaded hole 5 of the body 1 itself; said side plate 2 is configured to be rotatably constrained to the body 1 inserted in a first stave D and rotatably and slidingly to the body 1 inserted into a second stave D adjacent to the first.
Secondo una prima caratteristica peculiare del trovato, detta piastrina laterale 2 è dotata di un’asola 4A, disposta longitudinalmente alla piastrina stessa, la quale asola 4A è fissabile in modo scorrevole al corpo 1 del giunto corrispondente alla doga D adiacente alla precedente mediante una vite V, a tale scopo detto corpo 1 essendo dotato di almeno un ulteriore foro filettato laterale interno 5 nel quale viene avvitata detta vite V passante nell’asola 4A. According to a first peculiar characteristic of the invention, said side plate 2 is equipped with a slot 4A, arranged longitudinally to the plate itself, which slot 4A can be slidably fixed to the body 1 of the joint corresponding to the stave D adjacent to the previous one by means of a screw V, for this purpose said body 1 being provided with at least one further internal lateral threaded hole 5 into which said screw V passing through slot 4A is screwed.
Una seconda caratteristica peculiare del trovato, consiste nel fatto che detta piastrina laterale 2 è dotata di un incavo perimetrale 3B, collocato in prossimità della mezzeria della piastrina tra detto foro 5A e detta asola 4A, il quale incavo è configurato per cooperare con un nottolino 3 saldamente inserito in un rispettivo foro d’angolo 3A, predisposto nel corpo 1 con asse parallelo a quello di detti fori laterali interni 5 ed esterni 4. Detto nottolino 3 e detto incavo perimetrale 3B sono posizionati in modo tale che la piastrina laterale 2 ostacoli l’allineamento delle due doghe D a cui è vincolata girevolmente: in altre parole, grazie all’azione delle piastrine laterali 2 disposte alle due estremità di ogni doga D, le doghe stesse non possono giacere su uno stesso piano, ma sono sempre inclinate - seppur in modo esiguo – nella stessa direzione rispetto al piano del manto avvolgibile. Questo consente vantaggiosamente di ottenere che, quando la serranda avvolgibile viene abbassata fino ad accostare tra loro le doghe D, queste ultime si dispongono in posizione inclinata sempre e solo da una stessa parte. A second peculiar feature of the invention consists in the fact that said side plate 2 is equipped with a perimeter recess 3B, located near the center line of the plate between said hole 5A and said slot 4A, which recess is configured to cooperate with a pawl 3 firmly inserted in a respective corner hole 3A, arranged in the body 1 with axis parallel to that of said internal 5 and external 4 lateral holes. '' alignment of the two slats D to which it is rotatably linked: in other words, thanks to the action of the side plates 2 arranged at the two ends of each slat D, the slats themselves cannot lie on the same plane, but are always inclined - albeit in a small way - in the same direction with respect to the plane of the roller shutter. This advantageously allows to obtain that, when the rolling shutter is lowered until the slats D approach each other, the latter are always and only in an inclined position on the same side.
Una terza caratteristica peculiare del trovato, consiste nel fatto che le dimensioni delle doghe D e delle piastrine laterali 2 sono tali che ogni tentativo di sollevare spingendo dal basso verso l’alto il manto avvolgibile (fig. 7), anziché tirandolo dall’alto (fig. 6), causi l’impuntamento delle piastrine laterali 2 all’interno delle guide laterali (non mostrate) del manto stesso, fornendo intrinsecamente una efficace azione antiscasso. A third peculiar characteristic of the invention consists in the fact that the dimensions of the slats D and of the side plates 2 are such that any attempt to lift by pushing the roller shutter from the bottom upwards (fig. 7), instead of pulling it from above ( fig. 6), causes the side plates 2 to jam inside the side guides (not shown) of the mantle itself, intrinsically providing an effective anti-burglary action.
In altre parole, le doghe dotate alle loro estremità del giunto G secondo il presente trovato, costituiscono nel loro insieme una serranda autobloccante, che impedisce intrinsecamente il sollevamento del manto in caso di spinta dal basso verso l’alto. In other words, the slats equipped at their ends with the joint G according to the present invention, as a whole constitute a self-locking shutter, which intrinsically prevents the door from lifting in the event of a push from the bottom up.
Con riferimento alla figura 5, nella preferita forma realizzativa che si descrive, le doghe D sono tubolari, cioè cave, e il fissaggio dei giunti G alle due estremità di ciascuna doga D viene effettuato tramite l’impiego di coppie di perni longitudinali 6 che sono avvitabili sui fori laterali esterni 4 ed inseribili scorrevolmente all’interno delle doghe D. Una volta che il giunto G è stato inserito nella rispettiva doga D, è preferibilmente bloccato in sede mediante un punto di saldatura, realizzato tra il corpo 1 e l’estremità della doga G, o mediante altro mezzo idoneo a tale scopo. With reference to Figure 5, in the preferred embodiment that is described, the slats D are tubular, i.e. hollow, and the fixing of the joints G to the two ends of each slat D is carried out through the use of pairs of longitudinal pins 6 which are screwable on the external side holes 4 and slidably inserted inside the slats D. Once the joint G has been inserted in the respective slat D, it is preferably locked in place by means of a welding point, made between the body 1 and the end of stave G, or by other means suitable for this purpose.
Per semplicità costruttiva, i due fori filettati laterali esterni 4 e i due fori filettati interni 5, presenti nel corpo 1 del giunto G, sono preferibilmente fori passanti. For constructive simplicity, the two external lateral threaded holes 4 and the two internal threaded holes 5, present in the body 1 of the joint G, are preferably through holes.
E’ evidente che all’esempio di realizzazione fin qui descritto, a puro titolo illustrativo e non limitativo, potranno essere apportate modifiche, adattamenti, integrazioni, varianti e sostituzioni di elementi con altri funzionalmente equivalenti, senza peraltro uscire dall’ambito di protezione delle seguenti rivendicazioni. It is evident that the embodiment example described so far, for illustrative and non-limiting purposes, may be modified, adapted, integrated, modified and replaced with other functionally equivalent elements, without however departing from the scope of protection of the following claims.
