Description

STRUTTURA DI ANTA APRIBILE A SPORGERE SU FACCIATE CONTINUE VETRATE CON APPOGGIO PUNTUALE E SNODO SFERICO; DOOR STRUCTURE OPENABLE TO PROJECT ON CONTINUOUS GLASS FACADES WITH POINT SUPPORT AND BALL JOINT;

La presente invenzione riguarda il settore dell'edilizia, ed in particolare le facciate continue a vetri. The present invention relates to the building sector, and in particular to glass curtain walls.

In edilizia sono molto diffuse le facciate vetrate con appoggio puntuale del vetro e relativo snodo sferico, sistema a rotulle, spider glass, ò altri sistemi con calotte sferiche chiamati S.J.S. (Spheric Jaws System), sia per vetro semplice che per vetro camera. In construction, glass facades with punctual support of the glass and relative spherical joint, rotulle system, spider glass, or other systems with spherical caps called S.J.S. (Spheric Jaws System), both for single glazing and for double glazing.

Le facciate continue a vetri attualmente note sono fisse, senza la possibilità di realizzare ante apribili. The glass curtain walls currently known are fixed, without the possibility of making opening doors.

Scopo principale della seguente invenzione è la realizzazione di ante apribili a sporgere verso l'esterno, utilizzabili sia per vetro singolo che per vetro camera. The main purpose of the following invention is to produce doors that can be opened and protrude outwards, which can be used both for single glazing and for double glazing.

Ciò è stato ottenuto, secondo il trovato, prevedendo sostanzialmente di installare il vetro apribile su un telaio interno di supporto, il quale non insiste ne poggia sui vetri circostanti ma scarica gli sforzi sulla struttura di sostegno della vetrata continua senza sovraccaricare i vetri stessi. This has been achieved, according to the invention, by substantially providing for the installation of the glass that can be opened on an internal support frame, which does not insist on or rests on the surrounding glass panes but relieves the stresses on the support structure of the continuous glass pane without overloading the panes themselves.

Una migliore comprensione dell'invenzione si avrà con la seguente descrizione dettagliata ed i disegni allegati, che si riferiscono ad una preferita forma realizzativa relativa ad una facciata continua a vetro camera. A better understanding of the invention will be obtained with the following detailed description and the attached drawings, which refer to a preferred embodiment relating to a curtain wall with double glazing.

le figure 11 e 12 sono delle assonometrie che mostrano, rispettivamente dal lato esterno ed interno, un supporto atto a collaborare con gli elementi delle figure 9 e 10 per vincolare l'anta apribile alla struttura della facciata continua. Figures 11 and 12 are axonometries showing, respectively from the external and internal side, a support able to collaborate with the elements of Figures 9 and 10 to constrain the opening door to the structure of the curtain wall.

Con riferimento alle figure suddette, l'anta apribile Vi è costituita sostanzialmente da un modulo vetrato della facciata stessa, complanare esternamente con i vetri circostanti (fig. 1). With reference to the aforementioned figures, the opening door Vi is substantially constituted by a glazed module of the facade itself, externally coplanar with the surrounding glass (fig. 1).

Il vetro apribile VI è circondato da quattro vetri laterali fissi V2, V3, V4, V5 i quali hanno lo stesso spessore del vetro apribile VI, sono complanari ad esso e costituiscono, con i rispettivi lati adiacenti all'anta apribile VI, il telaio di battuta dotato di un'apposita guarnizione perimetrale 6 (Figg. 2, 3 e 6-8). The opening glass VI is surrounded by four fixed side windows V2, V3, V4, V5 which have the same thickness as the opening glass VI, are coplanar to it and constitute, with the respective sides adjacent to the opening door VI, the frame of stop equipped with a special perimeter gasket 6 (Figs. 2, 3 and 6-8).

La guarnizione 6 è atta ad incastonarsi nei vetri laterali V2-V5, in corrispondenza dei loro bordi che circoscrivono il vetro apribile Vi. The gasket 6 is able to fit into the side windows V2-V5, in correspondence with their edges which circumscribe the opening glass Vi.

A tale scopo, detti vetri laterali V2-V5 sono realizzati in modo tale che il listello separatore 5 interposto tra il vetro interno ed esterno del vetro camera, sia incassato rispetto al bordo di questi ultimi . For this purpose, said side windows V2-V5 are made in such a way that the separator strip 5 interposed between the internal and external glass of the double glazing is recessed with respect to the edge of the latter.

Secondo una caratteristica peculiare dell'invenzione, il vetro apribile VI va in battuta sulla guarnizione perimetrale 6 tramite un opportuno profilo perimetrale esterno 7 in plastica ed un opportuno profilo perimetrale interno 8 in estruso di alluminio, i quali sono uniti tra loro a ricoprire tutto il bordo dello stesso vetro apribile VI. According to a peculiar feature of the invention, the opening glass VI abuts against the perimeter gasket 6 by means of a suitable external perimeter profile 7 in plastic and an appropriate internal perimeter profile 8 in extruded aluminum, which are joined together to cover the entire edge of the same opening glass VI.

Il profilo in plastica 7 e il profilo in alluminio 8 sono accoppiati fra di loro preferibilmente tramite un incastro a coda di rondine; l'unione di questi profili 7 e 8 si ottiene pressando le appendici dell'incastro a coda di rondine del profilo in alluminio 8 contro il profilo in plastica 7. The plastic profile 7 and the aluminum profile 8 are coupled together preferably by means of a dovetail joint; the union of these profiles 7 and 8 is obtained by pressing the appendages of the dovetail joint of the aluminum profile 8 against the plastic profile 7.

Secondo una ulteriore caratteristica peculiare del trovato, detti profili perimetrali 7 e 8 accoppiati tra loro, costituiscono il telaio portante del vetro apribile VI. According to a further peculiar feature of the invention, said perimeter profiles 7 and 8 coupled together, constitute the bearing frame of the opening glass VI.

Vantaggiosamente, detto telaio che cinge il vetro apribile VI risulta essere a taglio termico ed è incastonato allo stesso, in quanto il vetro VI (che è preferibilmente un vetro camera) è lavorato nei bordi perimetrali in modo che i due vetri che lo compongono definiscano una sagoma che è complementare (a meno del gioco) a quella generata dall'unione dei due profili accoppiati 7 e 8. Advantageously, said frame that surrounds the opening glass VI has a thermal break and is embedded in it, since the glass VI (which is preferably a double glazing) is worked in the perimeter edges so that the two glasses that compose it define a shape that is complementary (except for the clearance) to that generated by the union of the two coupled profiles 7 and 8.

Dal punto di vista pratico, il serraggio dei profili accoppiati 7 e 8 intorno al vetro apribile VI, avviene applicando del sigillante siliconico nel piccolo spazio (gioco) esistente fra il vetro Vi ed i detti profili, inoltre questi ultimi vengono uniti con viti autofilettanti inserite nelle cave 9-10 del profilo estruso 8, e nella cava 11 del profilo in plastica, previo taglio a 45° dei profili stessi. From a practical point of view, the tightening of the coupled profiles 7 and 8 around the opening glass VI, takes place by applying silicone sealant in the small space (play) existing between the glass Vi and the said profiles, furthermore the latter are joined with self-tapping screws inserted in the grooves 9-10 of the extruded profile 8, and in the groove 11 of the plastic profile, after cutting the profiles at 45 °.

In questo modo il vetro apribile VI (preferibilmente vetro camera), è intelaiato su tutto il perimetro in maniera rigida e stabile. In this way, the opening glass VI (preferably double glazing) is framed around the entire perimeter in a rigid and stable manner.

I due vetri singoli (esterno ed interno) che compongono il vetro camera apribile VI, sono trattenuti meccanicamente dai profili perimetrali accoppiati 7 e 8. The two single glasses (external and internal) that make up the opening double glazing VI, are mechanically held by the paired perimeter profiles 7 and 8.

L'insieme del vetro apribile Vi e dei profili perimetrali 7 e 8 costituiscono l'anta apribile a sporgere . The set of the opening glass Vi and the perimeter profiles 7 and 8 constitute the opening to protrude door.

Secondo l'invenzione, tale anta è incernierata ad un supporto superiore 12 {vedi figg. 2 e 4-6) tramite almeno ,due tiranti in acciaio 13, alla cui estremità superiore è avvitato un occhiello 14, unito al supporto 12 tramite un perno filettato 15 che va a mordere sul supporto 12 stesso. According to the invention, this door is hinged to an upper support 12 (see figs. 2 and 4-6) by means of at least two steel tie rods 13, at the upper end of which an eyelet 14 is screwed, joined to the support 12 by means of a threaded pin 15 which bites into the support 12 itself.

Nell'esempio illustrato, ogni anta apribile VI ha due tiranti 13 verticali disposti in prossimità dei lati verticali dell'anta stessa. In the example illustrated, each opening door VI has two vertical tie rods 13 arranged in proximity to the vertical sides of the door itself.

I tiranti 13 sono filettati alle due estremità per essere collegati rigidamente alle appendici del profilo perimetrale in alluminio 8, tramite dei dadi e contro dadi 16, 17. Inoltre, il supporto 12 è fissato alla struttura portante tramite una barra filettata 18 in acciaio ed una staffa 19, mediante dadi e controdadi 20 di tipo noto. The tie rods 13 are threaded at both ends to be rigidly connected to the appendages of the aluminum perimeter profile 8, by means of nuts and counter nuts 16, 17. Furthermore, the support 12 is fixed to the supporting structure by means of a threaded steel bar 18 and a bracket 19, by means of known nuts and locknuts 20.

In particolare, la staffa 19 è fissata ad un montante 21 di tipo noto che costituisce la struttura portante dell'intero sistema. In particular, the bracket 19 is fixed to an upright 21 of a known type which constitutes the supporting structure of the entire system.

All'anta vetrata VI è preferibilmente collegato un motore elettrico 22, a sua volta fissato ad un'apposita staffa 23 solidale al montante 21, in modo che azionando il motore 22 l'anta Vi si apre a sporgere verso l'esterno. An electric motor 22 is preferably connected to the glazed sash VI, which is in turn fixed to a suitable bracket 23 integral with the upright 21, so that by operating the motor 22 the sash Vi opens to protrude outwards.

Nell'esempio illustrato, il vetro superiore V4 è sostenuto da una mensola 24 facente parte integrante del supporto 12. In the example illustrated, the upper glass V4 is supported by a shelf 24 which is an integral part of the support 12.

La guarnizione perimetrale 6, oltre che costituire la battuta fissa per l'anta apribile VI, funge anche da isolamento per il vetro V4 soprastante all'anta ed evita il contatto diretto fra vetro e metallo in corrispondenza della mensola 24. The perimeter gasket 6, in addition to constituting the fixed stop for the opening leaf VI, also acts as insulation for the glass V4 above the leaf and avoids direct contact between glass and metal at the shelf 24.

Nell'esempio illustrato, il tirante 13 e l'occhiello 14 che sostengono l'anta, sono decentrati rispetto all'asse della barra filettata 18, a cui è ancorato il supporto 12. In the example illustrated, the tie rod 13 and the eyelet 14 which support the door are off-centered with respect to the axis of the threaded bar 18, to which the support 12 is anchored.

Vantaggiosamente, per evitare che il peso dell'anta VI provochi la rotazione del supporto 12, sullo stesso viene avvitato un perno in acciaio 25, il quale si inserisce in un'asola orizzontale 26, ricavata nella staffa 19, impedendo la rotazione del supporto 12 e consentendo altresì la manovra di apertura dell'anta VI tramite il tirante 13 e del relativo occhiello 14. Advantageously, to avoid that the weight of the leaf VI causes the rotation of the support 12, a steel pin 25 is screwed onto it, which fits into a horizontal slot 26, obtained in the bracket 19, preventing rotation of the support 12 and also allowing the opening maneuver of leaf VI through the tie rod 13 and the relative eyelet 14.

Allo scopo di favorire il disimpegno in fase di apertura dei punti di contatto della guarnizione 7 con la guarnizione 6, il punto di rotazione dell'anta apribile Vi, corrispondente all'asse del perno filettato 15, si trova più in alto di circa 15÷30 mm rispetto all'asse della barra filettata 18, che è anche l'asse mediano fra il vetro fisso V4 e l'anta apribile VI. In order to facilitate the disengagement of the contact points of the gasket 7 with the gasket 6 during the opening phase, the pivot point of the opening leaf Vi, corresponding to the axis of the threaded pin 15, is about 15 ÷ higher. 30 mm with respect to the axis of the threaded bar 18, which is also the median axis between the fixed glass V4 and the opening leaf VI.

A tale proposito, giova osservare che detta posizione dell'asse del perno filettato 15 più alta dell'asse della barra filettata 18, è necessaria per favorire il disimpegno - in fase di apertura - della guarnizione 7 rispetto alla guarnizione 6. In caso contrario la prima guarnizione dovrebbe compenetrare la seconda. In this regard, it should be noted that said position of the axis of the threaded pin 15 higher than the axis of the threaded bar 18, is necessary to facilitate the disengagement - during the opening phase - of the gasket 7 with respect to the gasket 6. Otherwise, the the first seal should interpenetrate the second.

Secondo una caratteristica peculiare del trovato, con la soluzione tecnica ora descritta tutto il peso dell'anta apribile VI si scarica sulla staffa di sostegno 12, ed i quattro vetri perimetrali V2, V3, V4, V5 fungono, tramite la guarnizione 6, da semplice battuta per l'unta apribile VI senza essere sollecitati dall'azione di apertura e di chiusura dell'anta VI stessa. According to a peculiar feature of the invention, with the technical solution described above all the weight of the opening leaf VI is discharged onto the support bracket 12, and the four perimeter glasses V2, V3, V4, V5 act, through the gasket 6, as a simple stop for the opening anoint VI without being stressed by the opening and closing action of the wing VI itself.

Nell'esempio realizzativo che si descrive; la guarnizione 6 ed i profili accoppiati 7 - 8 vengono in contatto in tre punti: sul lato esterno il profilo perimetrale 7 comprime tre baffi 26 della guarnizione 6; in posizione intermedia la guarnizione 6 ha una pinna 27 che viene compressa in fase di chiusura da una appendice rigida (battuta) 28, facente parte del profilo rigido 7; mentre sul lato interno la guarnizione 6 fa battuta sul profilo perimetrale in alluminio 8. In the embodiment that is described; the gasket 6 and the coupled profiles 7 - 8 come into contact in three points: on the external side the perimeter profile 7 compresses three whiskers 26 of the gasket 6; in the intermediate position the gasket 6 has a fin 27 which is compressed in the closing phase by a rigid appendix (abutment) 28, forming part of the rigid profile 7; while on the internal side the gasket 6 abuts against the aluminum perimeter profile 8.

Secondo l'invenzione, si prevede che l'anta apribile VI sia registrabile secondo tre assi ortogonali: infatti sono previsti dei dadi e controdadi 16—17 tramite cui si effettuano le regolazioni verticali, inoltre nel profilo di alluminio 8, in corrispondenza dei tiranti 13, sono ricavate delle asole longitudinali che consentono la regolazione orizzontale dell'anta VI, ed infine sono previsti dei dadi e controdadi 20 che, agendo sulla barra filettata 18, consentono di effettuare delle regolazioni in senso ortogonale al vetro dell'anta apribile Vi. According to the invention, it is envisaged that the opening leaf VI can be adjusted according to three orthogonal axes: in fact there are nuts and locknuts 16-17 through which the vertical adjustments are made, furthermore in the aluminum profile 8, in correspondence with the tie rods 13 , longitudinal slots are obtained which allow horizontal adjustment of the leaf VI, and finally nuts and locknuts 20 are provided which, by acting on the threaded bar 18, allow adjustments to be made orthogonal to the glass of the opening leaf Vi.

La presente invenzione è stata descritta ed illustrata in una sua preferita forma di realizzazione, ma è chiaro che qualunque tecnico esperto del ramo potrà apportarvi modifiche e/o sostituzioni tecnicamente e/o funzionalmente equivalenti, senza peraltro esulare dall'ambito di tutela della presente privativa industriale. The present invention has been described and illustrated in a preferred embodiment thereof, but it is clear that any technician skilled in the art will be able to make changes and / or replacements that are technically and / or functionally equivalent, without however going beyond the scope of protection of this patent. industrial.
