METODO PER LA REALIZZAZIONE DI UN CUSCINO GONFIABILE E CUSCINO GONFIABILE OTTENUTO CON TALE METODO. METHOD FOR MAKING AN INFLATABLE CUSHION AND INFLATABLE CUSHION OBTAINED WITH THIS METHOD.

DESCRIZIONE DELL’INVENZIONE DESCRIPTION OF THE INVENTION

La presente invenzione si inserisce nel settore tecnico concernente i cuscini gonfiabili. The present invention is part of the technical sector concerning inflatable cushions.

E’ noto il brevetto IT n.1334853 della stessa richiedente in cui viene difeso un cuscino-poggiatesta gonfiabile ad uso dei passeggeri di mezzi di trasporto pubblico. Il cuscino difeso con il suddetto documento è ottenuto dalla termosaldatura, secondo percorsi predefiniti, di due facciate contrapposte di un foglio tubolare ad individuare una o due sacche e rispettivi condotti che mettono in comunicazione le sacche con l’esterno; ogni sacca e ogni condotto viene delimitato sull’interno dalla linea di termosaldatura e sull’esterno dal bordo del foglio che costituisce il cuscino. La parte terminale di ogni condotto è opportunamente conformata ad individuare una valvola di chiusura definita da una corrispondente appendice tubolare, ottenuta da un operazione di fustellatura e definente un boccaglio per l’introduzione deN’aria all’interno del condotto e della corrispondente camera; l’appendice, successivamente al gonfiaggio del cuscino viene ripiegata su se stessa il che impedisce la fuoriuscita di aria dalla camera: tale configurazione viene stabilizzata a seguito dell’introduzione dell’appendice medesima in un’apposita asola prevista nel foglio. Patent IT No. 1334853 of the same applicant is known, in which an inflatable headrest-pillow for use by public transport passengers is defended. The cushion defended with the aforementioned document is obtained by heat-sealing, according to predefined paths, two opposite sides of a tubular sheet to identify one or two pockets and respective ducts that connect the bags with the outside; each bag and each duct is delimited on the inside by the heat-sealing line and on the outside by the edge of the sheet that makes up the cushion. The terminal part of each duct is suitably shaped to identify a closing valve defined by a corresponding tubular appendix, obtained by a punching operation and defining a mouthpiece for the introduction of air into the duct and the corresponding chamber; the appendix, after the inflation of the cushion is folded back on itself, which prevents the escape of air from the chamber: this configuration is stabilized following the introduction of the appendix itself in a special slot provided in the sheet.

Tale cuscino presenta degli inconvenienti derivanti da fatto che sia le sacche che i condotti sono parzialmente delimitati dai bordi di detto foglio. This cushion has drawbacks deriving from the fact that both the bags and the ducts are partially delimited by the edges of said sheet.

Nel caso in cui lungo il/i bordo/i del foglio siano presenti dei difetti, quali ad esempio una lacerazione, il cuscino o non potrebbe essere gonfiato o l’aria introdotta all’interno del corrispondente condotto e relativa camera, verrebbe gradualmente rilasciata dal punto in cui si riscontra il difetto: il cuscino, pertanto risulterebbe imperfetto e inutilizzabile. In the event that defects are present along the edge (s) of the sheet, such as a tear, the cushion either could not be inflated or the air introduced into the corresponding duct and relative chamber, would be gradually released from the point where the defect is found: the cushion, therefore it would be imperfect and unusable.

Un altro inconveniente associato alla conformazione di detto cuscino deriva dal fatto che l’appendice definente la valvola di chiusura prevista nella parte terminale di ogni condotto, in seguito all’utilizzo del cuscino, può divincolarsi dall’apposita asola prevista nel foglio. Another drawback associated with the conformation of said cushion derives from the fact that the appendix defining the closing valve provided in the terminal part of each duct, following the use of the cushion, can free itself from the appropriate slot provided in the sheet.

La stabilizzazione dell’appendice è, infatti, unicamente demandata all’ancoraggio con la sede, pertanto in seguito al movimento della testa/spalle dell’utilizzatore tale appendice può sfilarsi dalla corrispondente sede e, quindi, si determina una perdita di tenuta del condotto e conseguentemente la corrispondente sacca si sgonfia gradualmente e il cuscino non svolge più la sua funzione. The stabilization of the appendix is, in fact, solely entrusted to the anchoring with the seat, therefore following the movement of the user's head / shoulders this appendix can come off from the corresponding seat and, therefore, a loss of seal of the duct is determined and consequently the corresponding bag gradually deflates and the cushion no longer performs its function.

La presente invenzione è quella di proporre un metodo per realizzare un cuscino gonfiabile che permetta di superare gli inconvenienti citati in premessa e nello specifico un metodo ottenuto con la combinazione di semplici fasi operative che velocizzano il ciclo produttivo. The present invention is to propose a method for making an inflatable pillow that allows to overcome the drawbacks mentioned in the introduction and specifically a method obtained with the combination of simple operating steps that speed up the production cycle.

Ancora una prerogativa dell’invenzione è quella di proporre un metodo che permetta di ottenere un cuscino gonfiabile realizzato in modo tale da garantire, in seguito al suo utilizzo, una pressione equilibrata al suo interno. Another prerogative of the invention is to propose a method that allows to obtain an inflatable pillow made in such a way as to ensure, following its use, a balanced pressure inside it.

Un’ulteriore prerogativa dell’invenzione è quella di fornire un metodo che permetta la realizzazione di un cuscino gonfiabile sia da un foglio tubolare sia da due fogli sovrapposti. A further prerogative of the invention is to provide a method that allows the creation of an inflatable pillow both from a tubular sheet and from two overlapping sheets.

Un'altra prerogativa dell’invenzione è quella di proporre un metodo che consenta di realizzare un cuscino gonfiabile di costo limitato. Another prerogative of the invention is to propose a method that allows to create an inflatable pillow of limited cost.

Le caratteristiche dell’invenzione risulteranno evidenti dalla seguente descrizione di una preferita forma di realizzazione del dispositivo in oggetto, in accordo con quanto riportato nelle rivendicazioni e con l’ausilio delle allegate tavole di disegno, nelle quali: The characteristics of the invention will become evident from the following description of a preferred embodiment of the device in question, in accordance with the contents of the claims and with the aid of the attached drawing tables, in which:

- la fig. 1 illustra una vista in pianta di un cuscino gonfiabile ottenuto con il metodo proposto; - fig. 1 shows a plan view of an inflatable pillow obtained with the proposed method;

- la fig. 2 illustra una vista ingrandita prospettica del cuscino gonfiabile ottenuto con il citato metodo; - fig. 2 shows an enlarged perspective view of the inflatable pillow obtained with the aforementioned method;

- la fig. 3 illustra una vista ingrandita prospettica dell’utilizzo del cuscino gonfiabile ottenuto con il metodo in oggetto. - fig. 3 shows an enlarged perspective view of the use of the inflatable pillow obtained with the method in question.

Il metodo per la realizzazione di un cuscino gonfiabile 1 prevede la sovrapposizione delle facciate contrapposte di un foglio tubolare di materiale plastico, ad esempio polietilene, o la sovrapposizione di due facciate. The method for making an inflatable pillow 1 provides for the overlapping of the opposite sides of a tubular sheet of plastic material, for example polyethylene, or the overlapping of two sides.

Si procede provvedendo alla termosaldatura delle facciate contrapposte secondo un percorso ad anello aperto, con la linea di saldatura S tale da delimitare almeno una camera C e un canale di adduzione D centrale, con quest’ultimo previsto per mettere in comunicazione la camera C con l’esterno. We proceed by heat sealing the opposite facades according to an open loop path, with the welding line S such as to delimit at least one chamber C and a central adduction channel D, with the latter provided to put chamber C in communication with the 'external.

La linea di saldatura S ad anello aperto segue un percorso predefinito che individua in corrispondenza del bordo trasversale superiore Bs, come illustrato nella fig. 1, una rientranza R che si sviluppa verso il canale di adduzione D a suddividere la camera C in due lobi L1, L2, distinti comunicanti tra loro e con detto canale di adduzione D. The open loop welding line S follows a predefined path which it identifies at the upper transverse edge Bs, as shown in fig. 1, a recess R which extends towards the adduction channel D to divide the chamber C into two distinct lobes L1, L2, communicating with each other and with said adduction channel D.

Successivamente si procede con la recisione del foglio superiormente ed inferiormente alla camera C e al canale di adduzione D a definire i corrispondenti bordi trasversali, superiore Bs ed inferiore Bi, del cuscino 1. Subsequently, the sheet is cut above and below the chamber C and the adduction channel D to define the corresponding transversal edges, upper Bs and lower Bi, of the cushion 1.

In prossimità del canale di adduzione D, contestualmente alla recisione di detto foglio, si recide quest’ultimo a costituire una valvola di chiusura K per detto canale di adduzione D; tale recisione prevede il taglio delle facciate del foglio in prossimità dell’uscita del canale di adduzione D ad originare due appendici 2, che definiscono un boccaglio per 1’introduzione deN’aria all'interno del canale di adduzione D, ed un’asola 3 lateralmente a quest’ultimo. In the vicinity of the adduction channel D, at the same time as the cutting of said sheet, the latter is cut to form a closing valve K for said adduction channel D; this cutting involves cutting the sheet faces near the outlet of the adduction channel D to give rise to two appendages 2, which define a mouthpiece for introducing the air into the adduction channel D, and a slot 3 lateral to the latter.

Si evidenzia che la valvola di chiusura K può essere realizzata successivamente all’ottenimento del cuscino 1, ossia dopo la recisione del foglio. It should be noted that the closing valve K can be made after obtaining the cushion 1, ie after cutting the sheet.

Il metodo proposto, come sopra descritto, permette di ottenere un cuscino gonfiabile che presenta caratteristiche particolarmente vantaggiose. The proposed method, as described above, allows to obtain an inflatable pillow which has particularly advantageous characteristics.

La linea di saldatura ad anello aperto delimita sia il canale di adduzione D sia i lobi L1 , L2, della camera C; tale delimitazione riduce la possibilità di difetti costruttivi, in quanto eventuali imperfezioni saranno legate esclusivamente alla linea di saldatura S e non più, come accadeva per il cuscino descritto in premessa, anche da eventuali lacerazioni dei bordi longitudinali del foglio tubolare costituente il cuscino noto. The open-loop welding line delimits both the adduction channel D and the lobes L1, L2, of the chamber C; this delimitation reduces the possibility of constructive defects, since any imperfections will be linked exclusively to the welding line S and no longer, as was the case for the cushion described in the introduction, also by possible tears of the longitudinal edges of the tubular sheet constituting the known cushion.

Il fatto di prevedere una camera C suddivisa in due lobi comunicanti tra loro e con un unico canale di adduzione D rende il cuscino più funzionale, in quanto l’aria immessa mediante l’unico canale di adduzione va ad interessare simultaneamente i due lobi L1 , L2. The fact of providing a chamber C divided into two lobes communicating with each other and with a single supply channel D makes the cushion more functional, as the air introduced through the single supply channel simultaneously affects the two lobes L1, L2.

L’aria all’interno del canale di adduzione D e dei lobi L1, L2, in seguito alla chiusura della valvola 3, si distribuisce al loro interno in modo equilibrato, proporzionalmente alla pressione esercitata dal collo e dalle spalle dell’utilizzatore sul cuscino, rendendo quest’ultimo maggiormente modellabile alla posizione più comoda per l’utilizzatore. The air inside the adduction channel D and the lobes L1, L2, following the closure of the valve 3, is distributed inside them in a balanced way, in proportion to the pressure exerted by the neck and shoulders of the user on the pillow, making the latter more moldable to the most comfortable position for the user.

Un unico canale di adduzione D previsto centralmente al cuscino con un’unica valvola di chiusura K dello stesso risulta vantaggioso, in quanto, successivamente all’utilizzo del cuscino, la valvola di chiusura viene riscontrata e mantenuta chiusa dalla pressione esercitata dalla schiena dell’utilizzatore, garantendone la tenuta e conseguentemente il cuscino sempre gonfio. A single adduction channel D provided centrally to the cushion with a single closing valve K of the same is advantageous, since, after the cushion is used, the closing valve is encountered and kept closed by the pressure exerted by the user's back , ensuring its tightness and consequently the pillow always swollen.

Un ulteriore vantaggio associato al metodo proposto deriva dal fatto che per la realizzazione del cuscino in oggetto può essere indistintamente utilizzato un foglio tubolare o due fogli sovrapposti; il canale di adduzione D e i lobi L1, L2, della camera C sono delimitati esclusivamente dalla linea di saldatura ad anello aperto di due facciate contrapposte. A further advantage associated with the proposed method derives from the fact that a tubular sheet or two superimposed sheets can be used without distinction to make the pillow in question; the adduction channel D and the lobes L1, L2 of the chamber C are delimited exclusively by the open-loop welding line of two opposite faces.

Altro vantaggio del metodo proposto deriva dal fatto che lo stesso è ottenuto dalla combinazione di semplici fasi operative che velocizzano il ciclo produttivo, in quanto con un'unica linea di saldatura S si ottengono le “parti” necessarie per definire un cuscino gonfiabile che sia funzionale e realizzato a bassi costi. Another advantage of the proposed method derives from the fact that it is obtained from the combination of simple operating phases that speed up the production cycle, since with a single welding line S, the necessary "parts" are obtained to define an inflatable cushion that is functional and made at low cost.

Va evidenziato vantaggiosamente che il foglio utilizzato per la realizzazione del cuscino 1 può essere o un foglio tubolare o due fogli sovrapposti che si svolgono in continuo da una bobina. Advantageously, it should be pointed out that the sheet used for making the cushion 1 can be either a tubular sheet or two superimposed sheets which are continuously unwound from a reel.

Si intende che quanto sopra è stato descritto a titolo esemplificativo e non limitativo per cui eventuali variazioni di natura pratico applicativa si intendono rientrare neN’ambito protettivo come sopra descritto e nel seguito rivendicato. It is understood that the above has been described by way of non-limiting example so that any variations of a practical applicative nature are intended to fall within the protective scope as described above and claimed hereinafter.
