DESCRIZIONE DI INVENZIONE INDUSTRIALE DESCRIPTION OF INDUSTRIAL INVENTION

L'oggeto del presente trovato non ha mai avuto pratica atuazione e conseguente vasta diffusione allo stato attuale della tecnica. Il dispositivo in oggetto, particolarmente studiato per disporre di un elemento galleggiante in acqua espansibile automaticamente a pressione atmosferica con ridottissime dimensioni di ingombro verticale, è fondamentalmente costituito da due parti: un involucro esterno di materiale plastico, impermeabile all’acqua e recante un’apertura per il passaggio dell’ ari a, costituita da un supporto munito degli atacchi per tubetti termoplastici, e un insieme di elementi di superficie costituenti le facce di un solido poliedrico, che, messe in tensione con precipui elementi elastici, vengono orientate e bloccate da un esclusivo pulsante scorrevole lungo una funicella flessibile fissata ad uno dei suddeti elementi. Lo sblocco del pulsante ed il suo relativo scorrimento lungo la fune consente ai suddetti elementi, costituenti le facce del solido geometrico, di conformarsi quasi istantaneamente in guisa di solido poliedrico, con la conseguente espansione dell’involucro plastico esterno. Ad espansione avvenuta, l’estremità del tubeto interno che ha consentito T immissione d’aria viene compressa tra un incavo di due pareti del poliedro, tale pressione blocca eventuali infilrazioni di altri fluidi, siano essi liquidi o gassosi. Per garantire maggiore sicurezza di ermeticità del dispositivo galleggiante, il pulsante che blocca e ativa la sua rapida espansione a pressione atmosferica, è realizzato in modo da costituire un’ulteriore chiusura sulla parte esterna del suddetto flessibile. Il suddetto pulsante, essendo anche galleggiante, esclude ogni possibile infiltrazione d’acqua durante la rapida espansione dell’involucro galleggiante. The object of the present invention has never had practical implementation and consequent wide diffusion in the current state of the art. The device in question, particularly designed to have a floating element in water that can be automatically expanded at atmospheric pressure with very small vertical dimensions, is basically made up of two parts: an outer casing of plastic material, impermeable to water and having an opening for the passage of the air, consisting of a support equipped with attachments for thermoplastic tubes, and a set of surface elements constituting the faces of a polyhedral solid, which, when put in tension with particular elastic elements, are oriented and blocked by a exclusive push-button sliding along a flexible cord fixed to one of the aforementioned elements. The release of the button and its relative sliding along the cable allows the aforementioned elements, constituting the faces of the geometric solid, to conform almost instantly in the guise of a polyhedral solid, with the consequent expansion of the external plastic casing. Once the expansion has taken place, the end of the internal tube that allowed the intake of air is compressed between a recess of two walls of the polyhedron, this pressure blocks any infiltration of other fluids, be they liquid or gaseous. To ensure greater safety of the hermetic seal of the floating device, the button that blocks and activates its rapid expansion at atmospheric pressure, is made in such a way as to constitute an additional closure on the outside of the aforementioned flexible. The aforementioned button, being also floating, excludes any possible infiltration of water during the rapid expansion of the floating envelope.

Queste ed altre caratteristiche di natura funzionale e costruttiva del dispositivo in oggetto, potranno essere meglio intese attraverso un esame particolareggiato delle figure del disegno allegato di cui: These and other functional and constructive characteristics of the device in question can be better understood through a detailed examination of the figures in the attached drawing of which:

in fig. (1) è rappresentato il dispositivo galleggiante visto in sezione ad espansione avvenuta; in fig. (1) the floating device is shown in section after expansion;

in fig. (2) è raffigurato il dispositivo galleggiante visto in sezione in fase di chiusura; in fig. (2) the floating device is shown seen in section during the closing phase;

in fig. (3) è raffigurato il medesimo dispositivo visto in pianta con raggiunta di una cintura per il fissaggio del medesimo alla vita di una persona. in fig. (3) the same device is shown seen in plan with a belt joining it for fastening it to a person's waist.

Con particolare riferimento alle figure del disegno allegato il dispositivo galleggiante in acqua, espansibile automaticamente a pressione atmosferica, risulta costituito da un involucro esterno in materiale plastico impermeabile all’acqua 1, recante un’apertura per il passaggio dell’aria, costituito da un supporto munito di attacchi 6 per tubetti termoplastici 5 e da un insieme di superfici tra loro interconnesse e idonee a formare un solido poliedrico 2 disposte su due piani, vedi fig. 3, e bloccate in tensione per l’azione di esclusivi elementi elastici 3 fissati alle superfici piane mediante gli agganci 4. La rapida espansione del dispositivo di galleggiamento è azionata dal pulsante 8 che consente lo scorrimento del medesimo lungo il filo flessibile 7. Ad espansione avvenuta, il tubetto flessibile 5 che consente il riempimento d’aria dell’involucro ermetico esterno 1 viene automaticamente compresso tra gli elementi di superficie costituenti le facce del poliedro 2. In fig. 3 è rappresentato il dispositivo galleggiante munito di passanti 10 per contenere la cintura 11 adatta all’eventuale sostentamento del medesimo in vita. Nella stessa figura è pure rappresentato il pulsante 8 munito di un galleggiante 9. With particular reference to the figures of the attached drawing, the floating device in water, which can be automatically expanded to atmospheric pressure, is constituted by an external casing in waterproof plastic material 1, with an opening for the passage of air, consisting of a support equipped with connections 6 for thermoplastic tubes 5 and by a set of interconnected surfaces suitable for forming a polyhedral solid 2 arranged on two planes, see fig. 3, and locked in tension by the action of exclusive elastic elements 3 fixed to the flat surfaces by means of the hooks 4. The rapid expansion of the flotation device is activated by the button 8 which allows it to slide along the flexible wire 7. Expansion once the flexible tube 5 which allows the air-tight filling of the external hermetic envelope 1 to be filled is automatically compressed between the surface elements constituting the faces of the polyhedron 2. In fig. 3 shows the floating device equipped with loops 10 to contain the belt 11 suitable for the eventual support of the same at the waist. The same figure also shows the button 8 equipped with a float 9.

Il trovato in oggetto è stato in precedenza descritto a puro titolo di esempio indicativo ma non limitativo delle caratteristiche del presente tovato. Da quanto in precedenza esposto, si deve dedurre che al dispositivo in oggetto potranno essere portate numerose varianti e modifiche senza uscire dall’ambito del presente trovato. The present invention has been previously described purely by way of indicative but not limitative example of the characteristics of the present invention. From the foregoing, it must be deduced that numerous variations and modifications may be made to the device in question without departing from the scope of the present invention.
