ANTECEDENTESDELAINVENCIÓNBACKGROUND OF THE INVENTION
En Ia actualidad, existen en el mercado distintos tipos de salvavidas hinchables, cuya disposición comprende unas paredes internas impermeables, susceptibles de llenarse con un gas a presión, de modo que al hincharse mantiene a flote al usuario. Concretamente, el peticionario del presente Modelo es titular del modelo español U200202540, referido a un sistema de salvavidas de reducido tamaño que se sitúa alrededor del cuello del usuario, y cuyo hinchado se efectúa gracias a un dispositivo de hinchado que actúa sobre el elemento hinchable que se encuentra recogido en su interior.At present, there are different types of inflatable lifeguards on the market, the arrangement of which comprises impervious internal walls, which can be filled with a pressurized gas, so that the swelling keeps the user afloat. Specifically, the petitioner of this Model is the owner of the Spanish model U200202540, referring to a small lifeguard system that is located around the neck of the user, and whose inflation is carried out thanks to a swelling device that acts on the inflatable element that It is collected inside.
Dichos salvavidas, de tipo compacto o concepto similar, están obligados, para alojar el elemento posteriormente hinchable, a utilizar carcasas desmontables, elementos hinchables elásticos carentes de rigidez o sistemas de un solo uso que a menudo dificultan su utilización y/o su posterior uso una vez hinchados.Said lifeguards, of a compact type or similar concept, are required, to accommodate the subsequently inflatable element, to use removable housings, elastic inflatable elements lacking stiffness or single-use systems that often hinder their use and / or their subsequent use. swollen
DESCRIPCIÓN DE LA INVENCIÓNDESCRIPTION OF THE INVENTION
El peticionario de Ia presente invención ha ideado un innovador contenedor para elementos hinchables de un salvavidas de tipo compacto, que viene a subsanar los inconvenientes anteriormente mencionados gracias a Ia utilización de un contenedor que de manera sencilla aloja el elemento hinchabie en su interior y permitiendo su inflado con facilidad, así como su reutilización posterior.The petitioner of the present invention has devised an innovative container for inflatable elements of a lifeguard of compact type, which comes to overcome the aforementioned drawbacks thanks to the use of a container that easily houses the inflatable element inside and allowing its inflated easily as well as your subsequent reuse
Concretamente; el contenedor para elementos hinchables adopta una forma toroidal de sección en forma de "C" que' presenta una abertura longitudinal y cuyo grosor es sensiblemente inferior en los extremos cerca de dicha abertura que en el lado opuesto donde es sensiblemente más grueso. En Ia posición del reposo del salvavidas, el elemento hlnchable permanece enrollado en el interior del contenedor, el cual gracias a su forma, siendo suficientemente flexible, posee Ia rigidez y dureza necesarias para mantenerse cerrado e impedir que el elemento hínchable salga involuntariamente de su alojamiento en su interior.Specifically; the container adopts a toroidal inflatable elements form shaped section "C"'presents a longitudinal opening and whose thickness is substantially less than at the ends near said opening on the opposite side where it is substantially thicker. In the position of the lifeguard rest, the inflatable element remains rolled inside the container, which thanks to its shape, being sufficiently flexible, has the rigidity and hardness necessary to keep closed and prevent the inflatable element from leaving its housing involuntarily. inside.
Independientemente del método que se use para inflar el salvavidas, cuando es hinchado el elemento hiπchable aumenta de volumen y se obliga a sí mismo a desenrollarse desplegándose y abriendo los bordes más delgados y flexibles del contenedor hacia fuera. Los espesores variables de la sección del contenedor, hacen que Ia estructura sólo se deforme parcialmente, para permitir Ia expansión del elemento hinchable que contiene en su interior, permaneciendo el resto del contenedor inalterable.Regardless of the method used to inflate the lifeline, when the hyper-swellable element is swollen, it increases in volume and forces itself to unwind by unfolding and opening the thinner and more flexible edges of the container outward. The variable thicknesses of the section of the container, make the structure only partially deformed, to allow the expansion of the inflatable element that it contains inside, the rest of the container remaining unchanged.
El contenedor para elementos hinchables objeto de la invención es idóneo para ser utilizado en cualesquiera productos que precisen alojar un elemento hinchable de una forma compacta y discreta pero que a Ia vez deban estar siempre listos para su uso inmediato, sin ninguna clase de preparativos.The container for inflatable elements object of the invention is suitable for use in any products that need to house an inflatable element in a compact and discreet manner but at the same time must always be ready for immediate use, without any preparations.
Por otra parte su estructura sirve además de protección contra los punzamientos, desgarros, luz solar, etc. a los que el elemento hinchable puede de otro modo estar expuesto, facilitando su manipulación y uso, manteniéndose plegado y protegido hasta su utilización.Moreover, its structure also serves as protection against punctures, tears, sunlight, etc. to which the inflatable element may otherwise be exposed, facilitating its handling and use, remaining folded and protected until its use.
Una vez utilizado y desinflado, el elemento hinchable se puede volver a colocar enrollado en el interior del contenedor para una próxima utilización, ya que este no ha sufrido alteración por su uso.Once used and deflated, the inflatable element can be re-rolled inside the container for a next use, since it has not been altered by its use.
El contenedor para elementos hinchables objeto de Ia invención, es por tanto un objeto de cuya configuración y estructura se derivan obviamente ventajas en su utilización para los sistemas de salvavidas de tipo compacto para los cuales ha sido concebido, dotándolos así de Ia capacidad de reutilización al no quedar deformado, de mantenimiento de Ia estabilidad del salvavidas una vez hinchado gracias a Ia rigidez de su constitución, asi como de Ia protección del elemento o elementos hinchables que aloja en su interior contra agresiones externas mientras está recogido y de Ia ausencia de carcasas contenedoras desmontables en el momento de uso ya que el contenedor para elementos hinchables de Ia invención Io es en sí mismo sin necesidad de desmontarse para su uso.The container for inflatable elements object of the invention, is therefore an object whose configuration and structure obviously derive advantages in its use for life-saving systems of compact type for which it has been conceived, thus providing them with the ability to reuse by not being deformed, maintaining the stability of the lifeguard once swollen thanks to the rigidity of its constitution, as well as the protection of the inflatable element or elements that it houses inside against external aggressions while it is collected and the absence of removable container housings at the time of use since the container for inflatable elements of the invention is in itself without the need to be disassembled for use.

Haciendo referencia a las figuras, se aprecia en ellas un ejemplo de realización preferida del contenedor para elementos hinchables que está constituido por un contenedor -1«, que en este caso adopta Ia forma de un salvavidas de tipo compacto y reducido tamaño en forma de collar, en el interior de! cual se encuentra recogido el elemento hínchable -2-,Referring to the figures, there is an example of a preferred embodiment of the inflatable container that is constituted by a container -1 «, which in this case takes the form of a lifeguard of compact type and reduced size in the form of a collar, inside! which is the pickable element -2-,
Dicho contenedor -1- se sitúa alrededor del cuello del usuario tal como se aprecia en la figura 1 , pudiéndose fijar mediante sistemas de enganche convencional, siendo de preferencia Ia utilización de un tipo de enganche constituido por sendas piezas cilindricas, una macho -3- y una hembra -4- que se introducen una dentro de Ia otra quedando fijadas gracias a sendas pestañas -5- que existen en su interior. Un caequillo -6- unido a un resorte -7- mantienen cerrado el enganche que se libera al realizar un movimiento hacia atrás del mencionado casquiilo -6-.Said container -1- is located around the neck of the user as seen in Figure 1, being able to be fixed by conventional hooking systems, preferably using a type of hook consisting of two cylindrical pieces, a male -3- and a female -4- that are introduced into the other being fixed thanks to two tabs -5- that exist inside. A bushing -6- attached to a spring -7- keeps the hitch that is released when a backward movement of the aforementioned casquiyl -6- closed.
Este sistema de fijación permite de una parte Ia facilidad de colocación y extracción del salvavidas por el usuario así como el perfecto acoplamiento del contenedor para elementos hinchables al mismo, dada Ia sección circular de ambos ver figura 2 y 3.This fixing system allows part of the ease of placement and removal of the lifeguard by the user as well as the perfect coupling of the container for inflatable elements to it, given the circular section of both see figures 2 and 3.
Otra ventaja adicional del sistema de enganche mencionado viene dada por Ia capacidad de las piezas cilindricas macho -3- y hembra -4- constitutivas del mismo, de alojar en su interior mecanismos adicionales, tai como una botella de CO2, utilizada en los sistemas automáticos de inflado, cuyo tamaño es irreducible, ofreciendo funciones de contenedor, sin incrementar Ia longitud del dispositivo.Another additional advantage of the aforementioned coupling system is given by the capacity of the male -3- and female -4- cylindrical parts constituting the same, to house additional mechanisms inside it, such as a CO2 bottle, used in automatic systems inflation, whose size is irreducible, offering container functions, without increasing the length of the device.
Como puede apreciarse en las figuras 4 a 6 en las que se ve representadas las distintas fases de inflado del elemento hinchable del contenedor para elementos hinchables, Ia sección del contenedor -1- presenta una zona -1a- de pared gruesa y sendas zonas -1b- sensiblemente más finas a ambos extremos de Ia abertura -1c- que presenta el contenedor -1- donde este adquiere Ia flexibilidad suficiente para permitir Ia salida del elemento hinchable -2- al exterior.As can be seen in Figures 4 to 6 in which the different inflation phases of the inflatable element of the inflatable container are represented, the section of the container -1- has a thick wall area -1a- and paths -1b - substantially thinner at both ends of the opening -1c- that the container -1- presents, where it acquires sufficient flexibility to allow the exit of the inflatable element -2- to the outside.
En estado de reposo, el contenedor -1" permanece prácticamente cerrado y el elemento hinchable -2- enrollado en su interior está protegido frente a golpes, rozaduras u otras agresiones que podrían dañarlo (figura 4); al accionarse el mecanismo de inflado del salvavidas, el gas expande el elemento 34In the rest state, the container -1 " remains practically closed and the inflatable element -2- rolled inside is protected against bumps, scratches or other aggressions that could damage it (figure 4); when the lifeguard inflation mechanism is activated , the gas expands the element 3. 4
