INFERRIATA MODULARE CON REGOLAZIONE DELLA LUNGHEZZA E DELLA LARGHEZZAâ€ MODULAR RAILS WITH LENGTH AND WIDTH ADJUSTMENTâ €

Lâ€™invenzione riguarda unâ€™inferriata modulare con regolazione della lunghezza e della larghezza, per applicazioni di diverso genere, come ad esempio per realizzare cancelli, recinzioni di abitazioni, grate di protezione per porte e finestre, e simili. The invention relates to a modular grating with length and width adjustment, for applications of various kinds, such as for making gates, house fences, protective gratings for doors and windows, and the like.

Sono note inferriate metalliche per le applicazioni piÃ¹ disparate, le quali sono costituite sostanzialmente da barre profilate di lunghezze diverse, che normalmente vengono disposte e fissate parallele fra loro nei sensi longitudinale e trasversale della relativa inferriata e sono realizzate con dimensioni tali da permetterne lâ€™adattamento per la rispettiva applicazione, ed in particolare tutte le barre longitudinali e trasversali vengono prima tagliate alle dimensioni fisse prestabilite e poi tutte queste barre vengono orientate nei relativi sensi longitudinale e trasversale e saldate fra loro, ed infine montate in modo tradizionale nelle corrispondenti posizioni di applicazione. Metal gratings are known for the most disparate applications, which substantially consist of profiled bars of different lengths, which are normally arranged and fixed parallel to each other in the longitudinal and transverse directions of the relative grating and are made with dimensions such as to allow their adaptation for the respective application, and in particular all the longitudinal and transverse bars are first cut to the predetermined fixed dimensions and then all these bars are oriented in the relative longitudinal and transverse directions and welded together, and finally mounted in a traditional way in the corresponding positions of application.

Questi tipi di inferriate, quindi, richiedono delle specifiche lavorazioni per venire installate nelle rispettive posizioni dâ€™applicazione, e non si prestano per venire utilizzate anche per applicazioni diverse, qualora si rendesse necessario. These types of railings, therefore, require specific processes to be installed in the respective application positions, and are not suitable for use also for different applications, should it be necessary.

La presente invenzione si propone lo scopo di eliminare gli inconvenienti descritti, mediante unâ€™inferriata sagomata in modo tale da poter regolare in misura diversa la lunghezza e la larghezza della stessa, per poterla impiegare cosÃ¬ in applicazioni comportanti dimensioni di installazione diverse. The present invention has the purpose of eliminating the drawbacks described, by means of a grating shaped in such a way as to be able to adjust its length and width to a different extent, in order to be able to use it in applications involving different installation dimensions.

Questâ€™inferriata Ã ̈ realizzata secondo lâ€™invenzione con le caratteristiche costruttive sostanzialmente descritte, con particolare riferimento alle allegate rivendicazioni del brevetto. This grating is made according to the invention with the construction characteristics substantially described, with particular reference to the attached patent claims.

Nelle suddette figure, viene rappresentata schematicamente unâ€™inferriata metallica modulare 7 con regolazione della lunghezza e della larghezza conforme alla presente invenzione, sagomata in modo da potere venire adattata ed installata in diverse posizioni dâ€™applicazione, per le applicazioni piÃ¹ disparate come ad esempio per realizzare cancelli, recinzioni di abitazioni, grate di protezione per porte e finestre, e simili. In the aforementioned figures, a modular metal railing 7 is schematically represented with length and width adjustment according to the present invention, shaped in such a way as to be adapted and installed in different application positions, for the most diverse applications such as example for making gates, house fences, protective gratings for doors and windows, and the like.

Come visibile particolarmente dalle fig. 1 e 2, questâ€™intelaiatura metallica modulare 7 Ã ̈ sostanzialmente costituita da una serie di barre profilate rettilinee allungate 8, nellâ€™esempio realizzate di forma quadrangolare, oppure anche di altre idonee forme, e da una serie di profili sagomati rettilinei allungati 9, 10 e 11 di forma piana oppure anche di altre idonee forme, che sono conformati e fissabili alle barre 8 nel modo e per la funzione che verranno descritti. As can be seen particularly from figs. 1 and 2, this modular metal framework 7 is substantially constituted by a series of elongated rectilinear profiled bars 8, in the example made of quadrangular shape, or also of other suitable shapes, and by a series of elongated rectilinear shaped profiles 9, 10 and 11 of flat shape or also of other suitable shapes, which are shaped and fixable to the bars 8 in the manner and for the function that will be described.

Le barre profilate 8 vengono tagliate alla grandezza desiderata e disposte parallele fra loro, distanziate delle distanze desiderate, e vengono poi appoggiate sui profili sagomati 9, 10 e 11 e sostenute dagli stessi, che ne determinano Î“ unione reciproca come verrÃ descritto. The profiled bars 8 are cut to the desired size and arranged parallel to each other, spaced by the desired distances, and are then placed on the shaped profiles 9, 10 and 11 and supported by the same, which determine mutual union as will be described.

Come visibile anche dalla fig. 4, in cui vengono mostrate due porzioni di barre profilate 8 parallele e distanziate fra loro, assieme ai profili sagomati 9, 10 e 11 separati dalle barre ed in fase di montaggio rispetto ad esse, si nota che tali profili sagomati sono costituiti sostanzialmente da un primo profilo metallico inferiore 9, da un secondo profilo metallico superiore 10 adattabile sul profilo inferiore 9 e da un terzo profilo metallico 11 adattabile sul secondo profilo 10. In particolare, il primo profilo 9 Ã ̈ piegato a forma di C per tutta la sua lunghezza, definendo un Iato piano inferiore 12 di grandezza maggiore dei restanti lati, e due corti lati piani superiori 13 e 14 di grandezza minore, leggermente distanziati dal lato piano maggiore 9 e raccordati alle estremitÃ dello stesso mediante relative superfici laterali piane 15 e 16, detti lati superiori 13 e 14 essendo allineati e complanari e distanziati fra loro in modo da definire un intervallo vuoto 17 comunicante con la cavitÃ intema 18 delimitata dai vari lati del primo profilo a C 9. As can also be seen from fig. 4, in which two portions of profiled bars 8 are shown parallel and spaced apart, together with the shaped profiles 9, 10 and 11 separated from the bars and in the assembly phase with respect to them, it is noted that these shaped profiles are substantially constituted by a first lower metal profile 9, a second upper metal profile 10 adaptable to the lower profile 9 and a third metal profile 11 adaptable to the second profile 10. In particular, the first profile 9 is bent in the shape of a C along its entire length , defining a lower flat side 12 of greater size than the remaining sides, and two short upper flat sides 13 and 14 of smaller size, slightly spaced from the greater flat side 9 and connected at the ends thereof by means of relative flat side surfaces 15 and 16, called upper sides 13 and 14 being aligned and coplanar and spaced apart so as to define an empty interval 17 communicating with the internal cavity 18 delimited. a from the various sides of the first C profile 9.

Come visibile sempre dalla fig. 4, nella cavitÃ interna 18 di ogni profilo sagomato 9 risultano scorrevoli in senso alternato svariati ganci di ancoraggio 19, identici fra loro e atti allâ€™appoggio ed al sostegno delle estremitÃ delle diverse barre profilate 8, ogni gancio di ancoraggio essendo sagomato con due corte e sottili piastrine piane e rettilinee 20 e 21 di forma parallelepipeda ed identiche fra loro, che vengono disposte parallele e leggermente distanziate e risultano unite fra loro da una piastrina trasversale 22 solidale alle stesse, e sono altresÃ¬ orientate e dimensionate in modo da venire alloggiate ed inserite scorrevolmente nella suddetta cavitÃ interna 18 del primo profilo sagomato 9. Tali piastrine piane 20 e 21 e piastrina trasversale 22, inoltre, sono solidali o fissate con due corti e sottili gambi verticali 23 e 24, interposti fra esse e simmetrici fra loro, i quali sono leggermente sporgenti verso lâ€™alto dalle piastrine stesse, e formati rispettivamente da una porzione rettilinea verticale 25 e 26 e da una porzione rettilinea orizzontale 27 e 28, piegata ortogonalmente rispetto alla relativa porzione verticale, e piÃ¹ corta della stessa, ed entrambe di forma parallelepipeda, dette porzioni orizzontali 27 e 28 essendo dirette verso lâ€™esterno in direzioni opposte fra loro ed orientate parallele alle relative piastrine piane 20 e 21, ed essendo dotate di un rispettivo foro passante filettato 29 e 30 per il passaggio del corrispondente gambo filettato 31 e 32 di una relativa vite 33 e 34, dotata di testa incavata 35 e 36, per lâ€™inserimento di una chiave (non mostrata) atta ad avvitare e svitare la vite stessa. As always visible from fig. 4, in the internal cavity 18 of each shaped profile 9 various anchoring hooks 19 slide alternately, identical to each other and suitable for supporting and supporting the ends of the different profiled bars 8, each anchoring hook being shaped with two short and thin flat and rectilinear plates 20 and 21 of parallelepiped shape and identical to each other, which are arranged parallel and slightly spaced and are joined together by a transverse plate 22 integral with them, and are also oriented and sized so as to be housed and slidably inserted in the aforementioned internal cavity 18 of the first shaped profile 9. These flat plates 20 and 21 and transverse plate 22, moreover, are integral with or fixed with two short and thin vertical legs 23 and 24, interposed between them and symmetrical to each other , which are slightly protruding upwards from the platelets themselves, and formed respectively by a vertical rectilinear portion 25 and 26 and by a straight horizontal portion 27 and 28, bent orthogonally with respect to the relative vertical portion, and shorter than the same, and both parallelepiped in shape, said horizontal portions 27 and 28 being directed outwards in opposite directions between them and oriented parallel to the relative flat plates 20 and 21, and being equipped with a respective threaded through hole 29 and 30 for the passage of the corresponding threaded shank 31 and 32 of a relative screw 33 and 34, equipped with a recessed head 35 and 36 , for the insertion of a key (not shown) suitable for tightening and unscrewing the screw itself.

Infine, le porzioni verticali 25 e 26 dei gambi 23 e 24 sono dotate di una relativa superficie di fondo dentellata 37 e 38 e sono distanziate fra loro di una misura tale da permettere l alloggiamento fra esse di una corrispondente barra profilata 8, in modo che questa venga appoggiata su tale superficie di fondo e risulti cosÃ¬ sostenuta dal relativo gancio dâ€™ancoraggio 19 e, dopo il suo fissaggio in posizione come verrÃ descritto, non possa sfilarsi orizzontalmente da tale posizione dâ€™applicazione grazie allâ€™attrito esercitato fra la superficie di contatto della barra stessa e detta superficie di fondo dentellata. A sua volta, il secondo profilo rettilineo 10 Ã ̈ sagomato a U ed Ã ̈ formato per tutta la sua lunghezza da un lato piano inferiore 39, dotato di una serie di asole passanti allungate 40 ad intervalli regolari, previste per la funzione che verrÃ descritta, e raccordato con due corti bordi laterali piani verticali e rialzati 41 e 42, definendo con ciÃ² una sede aperta per l alloggiamento di una serie di sottili piastre piane di bloccaggio 43, di forma parallelepipeda ed identiche fra loro, che in questa posizione alloggiata si dispongono a filo con la loro superficie superiore con la superficie superiore dei bordi laterali verticali 41 e 42. Tali piastre di bloccaggio 43 sono dotate di due rispettivi fori passanti 44 e 45 aventi lo stesso interasse dei fori filettati 29 e 30 dei gambi 23 e 24, per lâ€™inserimento dei gambi filettati delle viti 33 e 34, passanti anche attraverso una corrispondente asola passante 40 di detto secondo profilo 10. Tali piastre di bloccaggio 43 vengono alloggiate nella sede aperta del profilo superiore 10 e fatte scorrere nella stessa fino alla posizione di disposizione della sottostante barra 8, dove poi i fori filettati 29 e 30 di detti gambi 23 e 24 vengono fatti coincidere con i corrispondenti fori passanti 44 e 45 della relativa piastra di bloccaggio 43, in modo che i gambi filettati delle viti 33 e 34 vengano poi avvitati strettamente attraverso tutti questi fori filettati, serrando cosÃ¬ la piastra contro la corrispondente barra 8 e bloccandola pertanto in posizione. Infine, il terzo profilo 11 Ã ̈ sagomato in modo da risultare adattabile sopra il relativo profilo superiore 10 e le piastre di bloccaggio 43 alloggiate in questâ€™ultimo, dopo che tali piastre sono state serrate come sopra descritto sopra le diverse barre 8 disposte parallele ed opportunamente distanziate fra loro, in modo che lâ€™assieme profilo 10- piastre 43 venga coperto per tutta la sua estensione da ogni profilo superiore 11. Allo scopo, tale profilo superiore 11 Ã ̈ formato per tutta la sua lunghezza da un lato piano superiore 46 piegato ortogonalmente alle sue estremitÃ , per definire due bordi laterali piani verticali e ribassati 47 e 48 adattabili a scorrimento sui corrispondenti bordi piani verticali e rialzati 41 e 42 del secondo profilo 10, in modo che quando il profilo superiore 11 Ã ̈ completamente infilato sopra il profilo 10, questâ€™ultimo risulti coperto e non piÃ¹ visibile dallâ€™esterno. Nella fig. 3 viene illustrata una porzione di una barra 8 bloccata nella sua posizione di applicazione dallâ€™assieme profilo inferiore 9- gancio dâ€™ancoraggio 19-profilo superiore 10-piastra di bloccaggio 43, con il profilo di copertura 11 nella fase di scorrimento sul profilo superiore 10. Ogni inferriata modulare viene formata, come visibile particolarmente dalle fig. 1 e 2, unendo le estremitÃ superiori e le estremitÃ inferiori di tutte le barre 8, tagliate alla grandezza desiderata e disposte parallele e distanziate opportunamente fra loro, con un corrispondente assieme del tipo sopra specificato, nel quale tutti i ganci dâ€™ancoraggio 19 e tutte le piastre di bloccaggio 43 sono stati spostati lungo il relativo profilo 9 e 10, nelle posizioni corrispondenti fra loro e con le barre 8 e anche con una relativa asola passante 40, per permettere il fissaggio delle piastre contro i corrispondenti ganci dâ€™ancoraggio 19 nel modo sopra descritto. Finally, the vertical portions 25 and 26 of the shanks 23 and 24 are provided with a relative indented bottom surface 37 and 38 and are spaced apart by such a measure as to allow the housing between them of a corresponding profiled bar 8, so that this is placed on this bottom surface and is thus supported by the relative anchoring hook 19 and, after fixing it in position as described, cannot slip out horizontally from this application position thanks to the friction exerted between the contact surface of the bar itself and said notched bottom surface. In turn, the second straight profile 10 is U-shaped and is formed along its entire length by a lower flat side 39, equipped with a series of elongated through slots 40 at regular intervals, provided for the function that will be described , and joined with two short vertical and raised flat lateral edges 41 and 42, thereby defining an open seat for housing a series of thin flat locking plates 43, parallelepiped in shape and identical to each other, which in this housed position they arrange flush with their upper surface with the upper surface of the vertical lateral edges 41 and 42. These locking plates 43 are equipped with two respective through holes 44 and 45 having the same center distance as the threaded holes 29 and 30 of the stems 23 and 24 , for the insertion of the threaded stems of the screws 33 and 34, which also pass through a corresponding through slot 40 of said second profile 10. Said locking plates 43 are positioned in the open seat of the upper profile 10 and made to slide in it up to the position of arrangement of the underlying bar 8, where then the threaded holes 29 and 30 of said stems 23 and 24 are made to coincide with the corresponding through holes 44 and 45 of the relative locking plate 43, so that the threaded shanks of the screws 33 and 34 are then screwed tightly through all these threaded holes, thereby tightening the plate against the corresponding bar 8 and thereby locking it in place. Finally, the third profile 11 is shaped in such a way as to be adaptable above the relative upper profile 10 and the locking plates 43 housed in the latter, after these plates have been tightened as described above above the different bars 8 arranged parallel and suitably spaced from each other, so that the profile 10-plates 43 assembly is covered for its entire extension by each upper profile 11. For this purpose, this upper profile 11 is formed along its entire length on a flat side top 46 folded orthogonally at its ends, to define two flat vertical and lowered lateral edges 47 and 48 adaptable to sliding on the corresponding vertical and raised flat edges 41 and 42 of the second profile 10, so that when the upper profile 11 is completely inserted above profile 10, the latter is covered and no longer visible from the outside. In fig. 3 illustrates a portion of a bar 8 locked in its position of application by the lower profile assembly 9-anchoring hook 19-upper profile 10-locking plate 43, with the cover profile 11 in the sliding phase on the upper profile 10. Each modular railing is formed, as can be seen in particular from figs. 1 and 2, joining the upper ends and the lower ends of all the bars 8, cut to the desired size and arranged parallel and suitably spaced from each other, with a corresponding assembly of the type specified above, in which all the anchoring hooks 19 and all the locking plates 43 have been moved along the relative profile 9 and 10, in the positions corresponding to each other and with the bars 8 and also with a relative through slot 40, to allow the fixing of the plates against the corresponding hooks of anchor 19 in the manner described above.

Al termine del fissaggio di tutte queste parti componenti, lâ€™inferriata viene sollevata e di conseguenza le barre 8 vengono orientate in senso verticale, mentre i tre rispettivi profili 9, 10 e 11 situati alle due estremitÃ delle barre vengono orientati in senso orizzontale, rispettivamente nella posizione superiore e nella posizione inferiore delle barre stesse. At the end of the fastening of all these component parts, the railing is raised and consequently the bars 8 are oriented vertically, while the three respective profiles 9, 10 and 11 located at the two ends of the bars are oriented horizontally, respectively in the upper and lower positions of the bars themselves.

Allo scopo, i vari profili 9, 10 e 11 vengono normalmente fomiti dal produttore con misure di lunghezza standard, per poterli adattare alle lunghezze richieste della rispettiva inferriata In questo modo, se lâ€™inferriata da installare in una determinata posizione di montaggio presenta la stessa lunghezza od una lunghezza minore di tali profili 9, 10 e 11 , Ã ̈ sufficiente impiegare profili di lunghezza standard, mentre se tale inferriata presenta una lunghezza maggiore di quelle fomite, Ã ̈ necessario collegare ira loro, mediante opportuni connettori, i profili con le stesse e/o con diverse lunghezze standard, tagliando in senso longitudinale i profili cosÃ¬ collegati che dovessero risultare piÃ¹ lunghi della lunghezza richiesta.. For this purpose, the various profiles 9, 10 and 11 are normally supplied by the manufacturer with standard length measurements, in order to be able to adapt them to the required lengths of the respective grating. same length or a shorter length of these profiles 9, 10 and 11, it is sufficient to use profiles of standard length, while if this grating has a length greater than those provided, it is necessary to connect them, by means of suitable connectors, the profiles with the same and / or with different standard lengths, longitudinally cutting the profiles so connected that they should be longer than the required length.

Infine, ogni inferriata cosÃ¬ realizzata viene sostenuta in posizione eretta fissando le estremitÃ laterali, tagliate a misura, dei tre profili superiori e dei tre profili inferiori 9, 10 e 11 contro muri, colonne od altri idonei sostegni verticali, e questo fissaggio di ogni estremitÃ viene ottenuto impiegando la parte componente mostrata nelle fig. 5 e 6, che Ã ̈ sostanzialmente costituita da un supporto dâ€™ancoraggio 49 e da una placca di serraggio 50, di cui ogni supporto dâ€™ancoraggio 49 Ã ̈ formato da una sottile piastra piana 51 di forma quadrangolare o di altra idonea forma, di grandezza maggiore di quella dei tre profili 9, 10 e 11 uniti fra loro, la quale Ã ̈ dotata di una serie di fori passanti 52, nellâ€™esempio indicato formati da quattro fori, per rinserimento di relativi bulloni filettati (non mostrati), i cui gambi vengono avvitati in corrispondenti fori filettati (non indicati) praticati nel relativo sostegno verticale. Per eseguire questa operazione, la piastra piana 51 Ã ̈ dotata di superfici maggiori lisce 53 e 54 opposte fra loro e di un manicotto di sostegno 56 di forma quadrangolare, saldato alla piastra 51 in corrispondenza della sua superficie 53 e delimitante una cavitÃ passante assiale longitudinale 57, e provvisto di un foro passante 58 nella sua superficie laterale 59, detta piastra essendo appoggiata e fissata con lâ€™altra sua superficie (in questo caso, la superficie 54) contro il relativo sostegno verticale, al quale viene fissata tramite detti bulloni. A sua volta, la cavitÃ passante 57 del manicotto di sostegno 56 Ã ̈ dimensionata per alloggiare le corrispondenti estremitÃ sia del profilo inferiore 9, che viene disposto sul fondo piano della cavitÃ passante e sia dei profili 10 e 11 agganciati fra loro, che vengono disposti contro il cielo piano della cavitÃ passante stessa. In ogni manicotto di sostegno 56 viene poi inserita la placca di serraggio 50, per mantenere e fissare in posizione i rispettivi profili. Allo scopo, ogni placca di serraggio 50 Ã ̈ sostanzialmente costituita da due gambi verticali 60 e 61 identici e simmetrici e separati fra loro, i quali sono sagomati con una relativa porzione rettilinea verticale 62 e 63, le cui estremitÃ sono piegate ortogonalmente in modo da definire due corrispondenti corte porzioni orizzontali 64, 65 e 66, 67 rivolte verso lâ€™esterno in direzioni opposte fra loro, detta porzione verticale 63 essendo dotata di un foro passante filettato centrale 68 per linserimento di una vite di fissaggio 69, dotata di una testa incavata 70 per rinserimento di una chiave (non mostrata) atta ad avvitare e svitare la vite stessa. Ogni placca di serraggio 50 Ã ̈ dimensionata in modo da adattarsi fra i vari profili 9, 10 e 11, inserendo le porzioni verticali di gambo 62 e 63, le porzioni orizzontali inferiori di gambo 64 e 66 e le porzioni orizzontali superiori di gambo 65 e 67 nelle relative cavitÃ interne 18 e nelle sedi aperte di detti primo e secondo profilo 9 e 10, e facendo scorrere longitudinalmente la placca fino a fare coincidere fra loro i fori passanti 58 e 68 rispettivamente del manicotto di sostegno 56 e della placca di serraggio 50, ed avvitando poi completamente in questi fori la vite di fissaggio 69 con conseguente bloccaggio in posizione della placca di serraggio 50 contro i profili 9, 10 e 11. Finally, each railing made in this way is supported in an upright position by fixing the lateral ends, cut to size, of the three upper profiles and of the three lower profiles 9, 10 and 11 against walls, columns or other suitable vertical supports, and this fixing of each end is obtained by using the component part shown in figs. 5 and 6, which is substantially constituted by an anchoring support 49 and by a clamping plate 50, of which each anchoring support 49 is formed by a thin flat plate 51 of quadrangular shape or other suitable shape, larger than that of the three profiles 9, 10 and 11 joined together, which is equipped with a series of through holes 52, in the example indicated formed by four holes, for re-insertion of relative threaded bolts (not shown), the stems of which are screwed into corresponding threaded holes (not indicated) made in the relative vertical support. To carry out this operation, the flat plate 51 is equipped with larger smooth surfaces 53 and 54 opposite each other and with a support sleeve 56 of quadrangular shape, welded to the plate 51 at its surface 53 and delimiting a longitudinal axial through cavity. 57, and provided with a through hole 58 in its lateral surface 59, said plate being supported and fixed with its other surface (in this case, surface 54) against the relative vertical support, to which it is fixed by means of said bolts . In turn, the through cavity 57 of the support sleeve 56 is sized to house the corresponding ends of both the lower profile 9, which is arranged on the flat bottom of the through cavity, and the profiles 10 and 11 hooked together, which are arranged against the flat sky of the through cavity itself. The clamping plate 50 is then inserted into each support sleeve 56 to maintain and fix the respective profiles in position. For this purpose, each clamping plate 50 is substantially constituted by two vertical legs 60 and 61 identical and symmetrical and separated from each other, which are shaped with a relative vertical straight portion 62 and 63, the ends of which are bent orthogonally so as to define two corresponding short horizontal portions 64, 65 and 66, 67 facing outwards in opposite directions, said vertical portion 63 being provided with a central threaded through hole 68 for the insertion of a fixing screw 69, equipped with a recessed head 70 for reinserting a key (not shown) suitable for screwing and unscrewing the screw itself. Each clamping plate 50 is sized so as to fit between the various profiles 9, 10 and 11, by inserting the vertical stem portions 62 and 63, the lower horizontal stem portions 64 and 66 and the upper horizontal stem portions 65 and 67 in the relative internal cavities 18 and in the open seats of said first and second profiles 9 and 10, and making the plate slide longitudinally until the through holes 58 and 68 of the support sleeve 56 and of the clamping plate 50 coincide with each other. , and then completely screwing the fixing screw 69 into these holes with consequent locking in position of the clamping plate 50 against the profiles 9, 10 and 11.

Questa fase di installazione dellâ€™ inferriata viene eseguita dopo avere determinato la lunghezza e lâ€™altezza desiderate rispettivamente dei tre profili superiori e dei tre profili inferiori 9, 10 e 11 uniti fra loro e di tutte le barre profilate 8. This step of installing the railing is carried out after having determined the desired length and height respectively of the three upper profiles and the three lower profiles 9, 10 and 11 joined together and of all the profile bars 8.

Lâ€™inferriata conforme allâ€™invenzione puÃ² cosÃ¬ venire regolata nella sua lunghezza e larghezza in modo semplice e rapido, variando in misure diverse sia la disposizione reciproca dei tre profili superiori e dei tre profili inferiori 9, 10 e 11 lungo le relative barre profilate 8 e sia la disposizione delle diverse barre profilate 8 lungo tali profili superiori ed inferiori, il tutto con una serie di operazioni consistenti nell 'allentare i ganci di ancoraggio 19 e le relative piastre di bloccaggio 43, e nello spostare tali ganci dâ€™ancoraggio 19 in posizioni diverse lungo i relativi profili superiori ed inferiori, per variare cosÃ¬ la distanza fra le diverse barre profilate 8, e nello spostare i profili superiori ed inferiori in posizioni diverse lungo le barre profilate stesse, per variare cosÃ¬ la distanza fra i profili stessi, e nel fissare nuovamente il tutto nelle posizioni desiderate fissando le piastre di bloccaggio 43 contro i corrispondenti ganci dâ€™ancoraggio 19. The railing according to the invention can thus be adjusted in its length and width in a simple and rapid way, by varying in different sizes both the mutual arrangement of the three upper profiles and of the three lower profiles 9, 10 and 11 along the relative profiled bars 8 and the arrangement of the different profiled bars 8 along these upper and lower profiles, all with a series of operations consisting in loosening the anchoring hooks 19 and the relative locking plates 43, and in moving said hooks ™ anchor 19 in different positions along the relative upper and lower profiles, to thus vary the distance between the different profiled bars 8, and in moving the upper and lower profiles in different positions along the profiled bars themselves, to thus vary the distance between the profiles themselves, and in fixing everything again in the desired positions by fixing the locking plates 43 against the corresponding anchoring hooks 19.
