annessa a domanda di breveto per INVENZIONE INDUSTRIALE avente per titolo: SERIE DI ELEMENTI PER CREARE PANNELLI IN TESSUTO TESO TRA PROFILATI METALLICI E PROCEDIMENTO PER attached to a patent application for INDUSTRIAL INVENTION entitled: SERIES OF ELEMENTS TO CREATE PANELS IN FABRIC STRETCHED BETWEEN METALLIC PROFILES AND PROCEDURE FOR
L’UNIONE DI DETTI ELEMENTI AL TESSUTO . THE UNION OF THESE ELEMENTS TO THE FABRIC.
Formano oggeto del presente trovato una serie di elementi per creare pannelli in tessuto teso tra profilati metallici e il procedimento per l’unione di deti elementi al tessuto. The present invention relates to a series of elements for creating fabric panels stretched between metal profiles and the procedure for joining said elements to the fabric.
I pannelli in tessuto trovano la maggior applicazione per creare controsoffiti, pareti divisorie in stand, pannelli pubblicitari, pannelli per insegne luminose, schermi per proiezioni ed altro. The fabric panels are most used to create false ceilings, partitions in stands, advertising panels, panels for luminous signs, projection screens and more.
Sono noti diversi sistemi per agganciare un tessuto ad un profilato metallico; il più semplice e tradizionale è quello di fissare degli occhielli al bordo del tessuto e di inserire delle corde elastiche in deti occhielli e avvolgerle attorno al profilato metallico. Il sistema sopra descritto risulta esteticamente alquanto discutibile ed inoltre tra tessuto e profilato non esiste un collegamento continuo ma solo per punti favorendo la formazione nel tessuto di pieghe od ondulazioni non desiderate. Various systems are known for hooking a fabric to a metal section; the simplest and most traditional is to attach eyelets to the edge of the fabric and insert elastic cords in said eyelets and wrap them around the metal profile. The system described above is aesthetically somewhat questionable and furthermore there is no continuous connection between fabric and profile, but only by points, favoring the formation of unwanted folds or undulations in the fabric.
Un altro sistema prevede di unire il tessuto al profilato mediante rivettatura o aggraffatura con la conseguenza di non poter recuperare elasticamente l’eventuale telo lasco dovuto all’ inevitabile allungamento del tessuto. Another system involves joining the fabric to the profile by riveting or seaming with the consequence of not being able to elastically recover any loose sheet due to the inevitable stretching of the fabric.
Altri sistemi, utilizzati principalmente per creare pannelli adibiti ad insegne luminose, prevedono di appinzare il tessuto mediante clips che vengono inserite in appositi profilati in alluminio che prevedono una pluralità di dentelli che possono bloccare dette clips in varie posizioni per effettuare la tesatura. Other systems, mainly used to create panels used as luminous signs, provide for the fabric to be stiffened by means of clips which are inserted in special aluminum profiles which provide a plurality of teeth which can block said clips in various positions to carry out the stringing.
Anche con questi sistemi nel caso di allungamento del tessuto non si ha un recupero automatico del lasco ma occorre intervenire manualmente sulle clips per spostarle in corrispondenza dei dentelli più bassi. Even with these systems, in the case of stretching the fabric, there is no automatic recovery of the slack but it is necessary to manually intervene on the clips to move them in correspondence with the lower teeth.
Scopo del presente trovato è quello di eliminare i suddetti inconvenienti e di rendere disponibile una serie di elementi per creare pannelli di facile montaggio, esteticamente gradevole e con autotensionatura del tessuto in qualsiasi punto per garantire che il pannello si presenti sempre perfettamente piano. The purpose of the present invention is to eliminate the aforementioned drawbacks and to make available a series of elements for creating panels that are easy to assemble, aesthetically pleasing and with self-tensioning of the fabric at any point to ensure that the panel is always perfectly flat.
Detto scopo è pienamente raggiunto dalla serie di elementi per creare pannelli in tessuto teso tra profilati metallici, oggetto del presente trovato, che si caratterizza per quanto contenuto nelle rivendicazioni sotto riportate. Said object is fully achieved by the series of elements for creating fabric panels stretched between metal profiles, object of the present invention, which is characterized by the contents of the claims reported below.
Concorre al raggiungimento degli scopi prefissati anche il procedimento per l’unione di detti elementi al tessuto anch’esso caratterizzato per quanto contenuto nelle sotto riportate rivendicazioni. The procedure for joining said elements to the fabric also contributes to the achievement of the intended purposes, which is also characterized as contained in the claims below.
In particolare, la serie di elementi si caratterizza per il fatto che comprende un profilato strutturale che presenta una cavità interna e comunicante con l’esterno in cui vengono alloggiati dei barilotti di graffette elastiche provviste di steli elastici che sono a loro volta uniti ad un nastro che viene fissato al tessuto. In particular, the series of elements is characterized by the fact that it includes a structural profile which has an internal cavity communicating with the outside in which barrels of elastic clips are housed, provided with elastic stems which are in turn joined to a tape. which is fixed to the fabric.
Il procedimento prevede di realizzare una pluralità di graffette elastiche unite al nastro mediante iniezione di materiale plastico elastico in uno stampo in cui viene inserito anche un bordo di detto nastro. The method provides for making a plurality of elastic staples joined to the tape by injection of elastic plastic material into a mold in which an edge of said tape is also inserted.
Questa ed altre caratteristiche risulteranno meglio evidenziate dalla descrizione seguente di una preferita forma di realizzazione illustrata, a puro titolo esemplificativo e non limitativo, nella unita tavola di disegno, in cui: This and other characteristics will be better highlighted by the following description of a preferred embodiment illustrated, purely by way of non-limiting example, in the accompanying drawing table, in which:
- la figura 1 illustra in una sezione trasversale laverie di elementi che concorrono alla creazione del pannello; Figure 1 illustrates a washing cross section of elements which contribute to the creation of the panel;
- la figura 2 una pluralità di graffette elastiche di ancoraggio del tessuto ad un profilato metallico; - figure 2 a plurality of elastic clips for anchoring the fabric to a metal section;
- le figure 3 e 4 illustrano due viste, rispettivamente frontale e laterale, di una graffetta elastica in scala doppia di quella di figura 2. - figures 3 and 4 show two views, respectively front and side, of an elastic clip on a double scale of that of figure 2.
Con riferimento alle figure, con 1 è stato indicato un profilato strutturale in alluminio atto a formare una cornice di un pannello in un tessuto 2. With reference to the figures, 1 indicates an aluminum structural section suitable to form a frame of a panel in a fabric 2.
Il profilo strutturale 1 ha una cavità la sezione sostanzialmente circolare comunicante con una feritoia lb attraverso un canale le. The structural profile 1 has a cavity with a substantially circular section communicating with a slot 1b through a channel 1a.
Con 3 è stata indicata, nel suo complesso, una graffetta elastica che comprende un barilotto 4, sostanzialmente cilindrico, collegato tramite un peduncolo o stelo 5 elastico ad una pinzetta 6. Number 3 indicates, as a whole, an elastic clip which comprises a barrel 4, substantially cylindrical, connected by means of an elastic peduncle or stem 5 to a tweezers 6.
Il diametro del barilotto è leggermente inferiore al diametro della cavità la per consentirne il facile inserimento di lato in modo da bloccare le graffette elastiche al profilato strutturale 1. The diameter of the barrel is slightly less than the diameter of the cavity la to allow it to be easily inserted from the side in order to lock the elastic clips to the structural profile 1.
Le graffette elastiche 3 sono disposte lungo il bordo perimetrale del tessuto 2 ad un interasse di circa quindici millimetri e sono unite al tessuto in corrispondenza delle pinzette 6, con l'interposizione di un nastro 8, come sarà meglio evidenziato nella successiva descrizione del procedimento. The elastic staples 3 are arranged along the perimeter edge of the fabric 2 at a center distance of about fifteen millimeters and are joined to the fabric at the tweezers 6, with the interposition of a tape 8, as will be better highlighted in the subsequent description of the process.
Tutti i barilotti 4 delle graffette 3 sono tra di loro collegati da un cordone 7 per facilitare l'inserimento dei barilotti nella cavità la del profilato strutturale. All the barrels 4 of the clips 3 are connected to each other by a cord 7 to facilitate insertion of the barrels into the cavity la of the structural section.
Con 9 è stato indicato un profilato in alluminio che costituisce una scocca di copertura del profilato strutturale, detta scocca si innesta, tramite alette 10 al profilato strutturale che prevede delle sedi 11 per l'inserimento di dette alette. With 9 an aluminum section has been indicated which constitutes a body for covering the structural section, said body is coupled, by means of fins 10, to the structural section which provides seats 11 for the insertion of said fins.
La scocca di copertura è provvista , lungo <">la superficie esterna contrapposta alla feritoia lb, di una sede circolare 12 per l'inserimento di elementi cilindrici di collegamento di un altro pannello contiguo non illustrato. The covering body is provided, along the external surface opposite the slot 1b, with a circular seat 12 for the insertion of cylindrical connecting elements of another contiguous panel not shown.
Il procedimento, che forma pure oggetto del presente trovato, si riferisce alla formazione delle graffétte elastiche e all’unione delle stesse al tessuto. The process, which is also the subject of the present invention, refers to the formation of the elastic staples and to the union of the same to the fabric.
Il procedimento prevede la formazione di un nastro 8 comprendente una fascia 8a in poliestere o materiale sintetico equivalente e una fascia 8b in materiale misto poliestere e PVC o comunque un altro materiale facilmente termosaldabile. The process provides for the formation of a tape 8 comprising a band 8a in polyester or equivalent synthetic material and a band 8b in a mixed polyester and PVC material or in any case another easily heat-sealable material.
La fascia 8a del nastro 8 così formato viene inserita contemporaneamente al cordone 7 tra le due conchiglie di uno stampo che comprende le impronte di un gruppo di graffette elastiche, ad esempio dieci graffette. The band 8a of the band 8 thus formed is inserted simultaneously with the bead 7 between the two shells of a mold which comprises the impressions of a group of elastic staples, for example ten staples.
Effettuato l'inserimento di fascia e cordone tra le conchiglie, si procede alla chiusura dello stampo e all’ iniezione di un materiale plastico elastico come ad esempio un elastomero termoplastico. L’inserimento è effettuato in modo tale che il cordone 7 viene a trovarsi sostanzialmente al centro dei barilotti 4 e la fascia 8a tra le pinzette 6. Once the band and cord have been inserted between the shells, the mold is closed and an elastic plastic material such as a thermoplastic elastomer is injected. The insertion is carried out in such a way that the cord 7 is substantially located in the center of the barrels 4 and the band 8a between the tweezers 6.
Preferibilmente , ma non esclusivamente, l’elastomero impiegato è HYTREL (marchio registrato della Du Pont). Preferably, but not exclusively, the elastomer used is HYTREL (Du Pont registered trademark).
Effettuata l’iniezione si possono aprire le due conchiglie dello stampo e fare avanzare di un passo il nastro e il cordone per procedere ad una nuova iniezione di un gruppo di graffette elastiche. Once the injection has been made, the two shells of the mold can be opened and the tape and the bead can be advanced one step to proceed with a new injection of a group of elastic staples.
Si viene così a creare un nastro a cui sono saldamente ancorati per iniezione diretta le graffette elastiche per l’ancoraggio di un telo al profilato strutturale. This creates a tape to which the elastic clips for anchoring a sheet to the structural profile are firmly anchored by direct injection.
Occorre unire a questo punto il nastro 8 al tessuto 2 e questa unione avviene sovrapponendo il bordo del tessuto alla fascia 8b comprendente anche filamenti di PVC e sottoponendo detta fascia ad una saldo-pressatura ad alta frequenza che provoca la fusione del filamenti in PVC e la compenetrazione di detti filamenti nel tessuto sovrapposto. At this point it is necessary to join the tape 8 to the fabric 2 and this union takes place by superimposing the edge of the fabric to the band 8b also comprising PVC filaments and subjecting said band to a high frequency firm-pressing which causes the fusion of the PVC filaments and the interpenetration of said filaments in the superimposed fabric.
Ovviamente modifiche e varianti potranno essere previste , come ad esempio i barilotti delle graffette elastiche 3 potranno assumere una forma sferica o sostanzialmente sferica, così come l’unione del nastro 8 con il tessuto 2 potrebbe essere effettuata anche con l’impiego di adesivi, senza per altro uscire dall’ambito di tutela delle sotto riportate rivendicazioni. Obviously, modifications and variations can be provided, such as for example the barrels of the elastic staples 3 can assume a spherical or substantially spherical shape, as well as the union of the tape 8 with the fabric 2 could also be carried out with the use of adhesives, without however, to go beyond the scope of protection of the claims listed below.
