CINTURA SALVAGENTE AUTOGONFIABILE SELF-INFLATABLE LIFEBAND BELT

INTRODUZIONE : Cintura salvagente autogonfiabile per bagnanti e nuotatori azionabile in situazioni di emergenza e pericolo di annegamento a causa di malori, stanchezza, fondo marino insidioso, onde e correnti , anche nella pratica di sport acquatici come vela e windsurf. INTRODUCTION: Self-inflating life belt for swimmers and swimmers that can be operated in emergency situations and danger of drowning due to illness, fatigue, treacherous seabed, waves and currents, even in the practice of water sports such as sailing and windsurfing.

Il ritrovato Ã ̈ costituito da una camera d' aria stagna floscia di materiale gonfiabile elastico suddivisa in due scomparti alle cui estremitÃ sono applicate due bombolette ognuna delle quali Ã ̈ allacciata da un lato ad una semifÃ¬bbia , dall' altro lato alla camera d' aria mediante un blocchetto di immissione in cui Ã ̈ inserito l'otturatore a stelo della valvola di gonfiamento azionato da una trazione della cintura. The device consists of a watertight, watertight air chamber of elastic inflatable material divided into two compartments at the ends of which are applied two cans, each of which is connected on one side to a semi-fog lamp, on the other side to the chamber. air by means of an inlet block in which the stem shutter of the inflation valve is inserted, activated by a traction of the belt.

STATO DELLA TECNICA^ Sono noti svariati tipi di salvagente autogonfiabili nelle varie forme come giubbotti e cinture con vari sistemi di gonfiaggio come reagenti o bombole di gas compresso che azionati in caso di necessitÃ sviluppano un aumento di volume per favorire il galleggiamento . BACKGROUND OF THE INVENTION Various types of self-inflating life jackets are known in various forms such as vests and belts with various inflation systems such as reagents or compressed gas cylinders which, activated in case of need, develop an increase in volume to favor buoyancy.

INCONVENIENThdei dispositivi sopra descritti : DRAWBACK of the devices described above:

-eccessivo ingombro, da cui risulta l' impossibilita di utilizzo durante il nuoto - excessive bulk, resulting in the impossibility of use during swimming

- scarsa praticitÃ di azionamento per mezzo di leve o pulsanti difficili da manovrare in momenti di panico - poor operating convenience by means of levers or buttons that are difficult to maneuver in moments of panic

-costi di ricarica eccessivi per la sostituzione dÃ¬ bombolette e difficoltÃ di preparazione -sviluppo circonferenziale eccessivo, dopo il gonfiamento, che ostacola il nuoto - scarsa sicurezza per difficoltÃ di controllo per difetti o guasti non visibili. - excessive refill costs for the replacement of cans and preparation difficulties - excessive circumferential development, after inflation, which hinders swimming - poor safety due to difficulties in checking for defects or faults that are not visible.

VANTAGGI del ritrovato : ADVANTAGES of the invention:

-minimo ingombro e massima sicurezza con la separazione in due scompartÃ¬ -praticitÃ di azionamento con una semplice trazione della cintura -minimal bulk and maximum safety with the separation into two compartments -practical operation with a simple pull of the belt

-semplicitÃ di ricarica e costo modesto con l'utilizzo di una bombola di rifornimento senza alcuna operazione di sostituzione - ease of refilling and modest cost with the use of a refueling cylinder without any replacement operation

-allungamento modesto per lo sviluppo differenziato a lobi della camera d' aria -facile verifica delle cariche delle bombolette grazie al materiale trasparente. - modest elongation due to the differentiated lobe development of the air chamber - easy verification of the cans charges thanks to the transparent material.

ELEMENTI COSTRUTTIVI: CONSTRUCTION ELEMENTS:

Camera d'aria tubolare di forma lineare allungata in due scompartÃ¬ con estremitÃ chiuse allacciate a semifibbie assieme a bombolette di gas liquido le quali presentano ognuna una valvola di gonfiaggio { con otturatore a stelo inserito in un punto di immissione alla camera d'aria) ed un'altra valvola con cui alla fine dell'utilizzo la cintura autogonfiabile puÃ² essere facilmente sgonfiata ed in seguito ricaricata. ESEMPIO COSTRUTTIVO Tubular bladder of elongated linear shape in two compartments with closed ends fastened to semi-buckles together with liquid gas cylinders which each have an inflation valve {with stem plug inserted in an entry point to the bladder) and another valve with which at the end of use the self-inflating belt can be easily deflated and subsequently recharged. CONSTRUCTION EXAMPLE

Le figure 1) e 2) rappresentano la cintura salvagente nel suo insieme con la camera d' aria (1) con la sigillatura di separazione (2) costituente due scompartÃ¬ con alle estremitÃ le semifibbie (3) e (4) ove si trovano le bombolette(5) allacciate mediante fettucce inestensibili e flessibili (10) assieme alle estremitÃ della camera d' aria stessa (1) fissate da anelli piatti di bloccaggio (6). Figures 1) and 2) represent the life belt as a whole with the air chamber (1) with the separation seal (2) constituting two compartments with the semi-buckles (3) and (4) at the ends where they are located the cans (5) fastened by inextensible and flexible straps (10) together with the ends of the air chamber itself (1) fixed by flat locking rings (6).

Al lato opposto delle bombolette (5) le valvole di gonfiamento con blocchetto di immissione (8)applicate alla camera d' aria estensibile (1) costituiscono un abbinamento di un sistema inestensibile ad un tratto elastico che, alla trazione, provoca l' apertura dell' otturatore della valvola solidale col blocchetto di immissione (8) ed il gonfiamento dovuto al passaggio del gas. On the opposite side of the cans (5), the inflation valves with inlet block (8) applied to the extendable air chamber (1) constitute a combination of an inextensible system with an elastic section which, upon traction, causes the opening of the valve obturator integral with the inlet block (8) and the swelling due to the passage of gas.

Le linee tratteggiate (7) della figura 1) indicano la forma che assumerÃ la camera d' aria formando quattro lobi di rigonfiamento a causa della deformazione differenziata predeterminata . The dotted lines (7) of figure 1) indicate the shape that the air chamber will take, forming four swelling lobes due to the predetermined differentiated deformation.

Le figure 8) 9) 10) mostrano le fasi di gonfiamento della cintura salvagente e la risalita della stessa dalla vita dell' utente alla posizione sotto le ascelle. Figures 8) 9) 10) show the phases of inflation of the life jacket and its ascent from the user's waist to the position under the armpits.

La figura 5) mostra Î“ operazione di ricarica che avviene premendo il cappellotto della valvola (9) per mezzo del beccuccio erogatore del contenitore del gas liquido di rifornimento (dopo aver effettuato lo sgonfiamento e la chiusura della valvola di immissione premendo il blocchetto (8). Figure 5) shows Î "refilling operation which takes place by pressing the valve cap (9) by means of the dispensing spout of the liquid refueling gas container (after having deflate and closed the inlet valve by pressing the block (8 ).

La figura 6} mostra la posizione di chiusura di ambedue le valvole. Figure 6} shows the closed position of both valves.

La figura 7 ) mostra la posizione di apertura delle due valvole in fase di sgonfiamento della cintura salvagente dopo l'utilizzo; mostra inoltre il sistema di molle a lamina a scatto (18) che determina la posizione aperto/chiuso degli otturatori (12) e (14)alla applicazione di una certa forza. Figure 7) shows the opening position of the two valves during the deflation phase of the life jacket after use; it also shows the snap leaf spring system (18) which determines the open / closed position of the shutters (12) and (14) when a certain force is applied.

Il funzionamento risulta evidente cosi come la praticitÃ delle operazioni. Il materiale trasparente delle bombolette e del contenitore di rifornimento permette di controllare visivamente lo stato della carica del dispositivo. The functioning is evident as well as the practicality of the operations. The transparent material of the cans and the refill container allows you to visually check the charge status of the device.

Il trovato puÃ² venire modificato mantenendo il concetto inventivo che ne Ã ̈ alla base potendosi sostituire ogni dettaglio con altro tecnicamente equivalente. The invention can be modified while maintaining the inventive concept underlying it, being able to replace every detail with another technically equivalent.
