Campo de la invención Field of the Invention

La presente invención se engloba dentro del campo de los aparatos de medición, y más en concreto, se refiera a un aparato que informa visualmente sobre el volumen de gas en 5 una bombona o botella. The present invention falls within the field of measuring devices, and more specifically, refers to an apparatus that visually informs about the volume of gas in a bottle or bottle.

Antecedentes de la invención Background of the invention

En la actualidad, se conocen medidores similares. At present, similar meters are known.

La patente US 8171784 se refiere a un indicador del volumen de gas residual en una bombona de gas. El indicador dispone de un elemento portador que tiene una parte para 10 contener peso y una parte para aplicar presión, un cilindro hidráulico, el cual tiene un cuerpo de cilindro que contiene a un fluido hidráulico y un pistón del cilindro sujeto contra la parte para aplicar presión del elemento portador, siendo el pistón móvil con respecto a dicha parte para aplicar presión de manera que se fuerza al fluido hidráulico a salir del cilindro cuando se recibe un cierto peso en la parte contenedora de peso. Además se 15 dispone un medidor hidráulico de tipo mecánico que tiene una aguja rotatoria sobre una escala y una tubería que conduce el fluido desde el cilindro hidráulico hasta el medidor hidráulico. Es decir, la determinación del volumen de gas contenida dentro de la bombona se realiza por un simple pistón, relleno de fluido, de forma que cuando una bombona se sitúa en la zona correspondiente del dispositivo, dicho peso mueve el émbolo del pistón y 20 a su vez se mueven fluido fuera de dicho pistón y dicha presión hace girar la aguja del medidor hidráulico. Por tanto, este sistema se basa en la utilización de un fluido contenido dentro de un pistón para indicar la cantidad de gas en el interior de una bombona. US Patent 8171784 refers to an indicator of the volume of waste gas in a gas cylinder. The indicator has a carrier element that has a part to contain weight and a part to apply pressure, a hydraulic cylinder, which has a cylinder body containing a hydraulic fluid and a cylinder piston held against the part to apply pressure of the carrier element, the mobile piston being relative to said part to apply pressure so that the hydraulic fluid is forced out of the cylinder when a certain weight is received in the weight-containing part. In addition, a mechanical type hydraulic meter is provided that has a rotating needle on a scale and a pipe that conducts the fluid from the hydraulic cylinder to the hydraulic meter. That is, the determination of the volume of gas contained within the cylinder is performed by a simple piston, filled with fluid, so that when a cylinder is located in the corresponding area of the device, said weight moves the piston piston and 20 a in turn, fluid is moved out of said piston and said pressure rotates the needle of the hydraulic meter. Therefore, this system is based on the use of a fluid contained within a piston to indicate the amount of gas inside a cylinder.

El dispositivo comprende de una manera 25 concéntrica un soporte 2 que coopera con el fondo de la botella y de un zócalo 1 en cuyo interior se monta el soporte 2 y que está relacionado con el mismo a través de unos resortes 3. Siendo el soporte 2 apto para descender bajo el efecto del peso de la botella con respecto al zócalo 1, comprimiendo los resortes 3, los cuales cuando la botella se va consumiendo van empujando verticalmente al soporte 2 el cual dispone de medios de 30 indicación visual 6 del volumen de gas restante que hay en el interior de la botella. El dispositivo presenta, en el soporte 2, tres elementos 2c que contienen en su interior a los resortes 3, también el soporte presenta elementos 2d para centrar la posición de la botella y de una superficie de apoyo de la bombona 2a la cual está más baja que los elementos 2c y 2d. 35 EP 1271113 describes a permanent device for visually assessing the level of consumption of a gas bottle. The device comprises in a concentric manner 25 a support 2 that cooperates with the bottom of the bottle and a socket 1 inside which the support 2 is mounted and which is related to it through springs 3. The support 2 being suitable to descend under the effect of the weight of the bottle with respect to the socket 1, compressing the springs 3, which when the bottle is consumed are pushing vertically to the support 2 which has means of 30 visual indication 6 of the volume of gas remaining inside the bottle. The device has, on the support 2, three elements 2c containing inside the springs 3, the support also presents elements 2d to center the position of the bottle and a support surface of the bottle 2a which is lower than elements 2c and 2d. 35

La patente EP 0853235 describe un indicador de nivel para una botella de gas licuado presurizado. El indicador comprende un anillo inferior sobre el que se dispone la botella y que presenta tres pies de apoyo 5, 6 y 7/8. Uno de los pies de apoyo 7/8 incorpora un sistema para medir el peso de la botella y su contenido. El sistema de medición está programado con un peso inicial de la botella llena o con un peso final de la botella vacía. 40 El sistema de pesado puede ser de tipo mecánico utilizando una palanca 12 que actúa sobre un resorte comprimido que indica el nivel sobre una escala 16 (ver figura 3). El sistema de medición también puede ser de tipo electrónico con un dispositivo sensor de peso electrónico convencional. EP 0853235 describes a level indicator for a bottle of pressurized liquefied gas. The indicator comprises a lower ring on which the bottle is arranged and which has three support feet 5, 6 and 7/8. One of the 7/8 support feet incorporates a system to measure the weight of the bottle and its contents. The measuring system is programmed with an initial weight of the full bottle or with a final weight of the empty bottle. 40 The weighing system can be mechanical using a lever 12 that acts on a compressed spring that indicates the level on a scale 16 (see figure 3). The measurement system can also be of the electronic type with a conventional electronic weight sensing device.

La patente CN 201277441 describe una base de sujeción de cualquier objeto, pero 45 especialmente diseñada para apoyar una botella de gas licuado. Dicha base contiene una CN patent 201277441 describes a support base for any object, but specially designed to support a bottle of liquefied gas. That base contains a

plataforma superior móvil y una plataforma inferior fija que descansa sobre suelo, entre las cuales se disponen una pluralidad de resortes 1, y asociada a la plataforma móvil hay una aguja indicadora que señala el nivel da gas sobre una escala fija dispuesta en un lateral de la base (ver figura 1). El funcionamiento de la base de medición es muy simple, cuando se deposita una bombona encima de la misma los muelles se comprimen y la 5 aguja indicadora se desplaza verticalmente con respecto a la escala indicando el nivel de peso o cantidad de gas en el interior de la botella. Este dispositivo es de gran simpleza puesto que básicamente es una báscula mecánica basada en la utilización de resortes. upper mobile platform and a fixed lower platform resting on the ground, between which a plurality of springs 1 are arranged, and associated with the mobile platform is an indicating needle that indicates the level of gas on a fixed scale arranged on one side of the base (see figure 1). The operation of the measuring base is very simple, when a cylinder is deposited on top of it, the springs are compressed and the indicator needle moves vertically with respect to the scale indicating the level of weight or quantity of gas inside the bottle This device is very simple since it is basically a mechanical scale based on the use of springs.

En ninguno de dichos documentos se ha encontrado referencia alguna a la existencia de un dispositivo de medida del volumen de gas en el interior de una botella o bombona de 10 gas que esté basado en la utilización conjunta de al menos un resorte y de la comprensión de un fluido y que a su vez lo haga a través de un recipiente que contiene a la propia bombona, y no sobre platillos o plataformas sobre las que se deposita la bombona. Esto tiene la ventaja de que es el propio peso de la bombona que mueve uno de los dos recipientes cooperantes y su desplazamiento relativo hace las veces de 15 indicador sin costosos sensores o indicadores hidráulicos que actúan sobre sus correspondientes medidores. Cualquier sensor o indicador de palanca puede estropearse o trabarse originando un fallo en la lectura. In none of these documents has any reference been found to the existence of a device for measuring the volume of gas inside a gas bottle or cylinder that is based on the joint use of at least one spring and the understanding of a fluid and that in turn do it through a container that contains the bottle itself, and not on saucers or platforms on which the bottle is deposited. This has the advantage that it is the weight of the cylinder that moves one of the two cooperating vessels and its relative displacement acts as an indicator without expensive sensors or hydraulic indicators acting on their corresponding meters. Any sensor or lever indicator can be damaged or locked causing a reading failure.

Otras ventajas que tiene el medidor objeto de la invención son las siguientes: los materiales con los que se construyen los recipientes cooperantes y el fluido utilizado en 20 su interior son convencionales y baratos, lo que hace que el precio final del medidor sea muy competitivo. Es un medidor que puede acoplarse a cualquier tipo de bombona bien sea de camping, de soldadura, submarinismo o de las utilizadas en el hogar. La variación entre los modelos del medidor será mínima, añadiendo únicamente algún complemento de fijación para las bombonas grandes y complementos como un asa y una tapa para las 25 bombonas pequeñas. Y por último, el dispositivo de medida es ligero, sin mecanismos ni aparatos de medida electrónicos y no representa un peso adicional a las ya pesadas bombonas. Other advantages of the meter object of the invention are the following: the materials with which the cooperating vessels are constructed and the fluid used in its interior are conventional and cheap, which makes the final price of the meter very competitive. It is a meter that can be attached to any type of cylinder, whether camping, welding, diving or those used in the home. The variation between the meter models will be minimal, adding only some fixing complement for large bottles and accessories such as a handle and a cover for the 25 small bottles. And finally, the measuring device is lightweight, without electronic devices or measuring devices and does not represent an additional weight to the already heavy cylinders.

Descripción de la invención Description of the invention

Es un objeto de la invención informar del volumen de gas que tiene una bombona 30 mediante un sencillo indicador visual y sin necesidad de sopesarla de forma subjetiva alzándola o agitándola. Esto se logra con un recipiente que contiene a la bombona. Este recipiente es interior a otro recipiente que lo contiene y que se denomina recipiente exterior. Entre ambos recipientes cooperantes se dispone un líquido y un elemento elástico. El elemento elástico es necesario porque el peso de la bombona es alto y para 35 realizar un medidor únicamente con líquido y el principio de Arquímedes, el volumen de líquido sería muy grande y el medidor inviable por su gran tamaño. Así que se calcula la constante K del muelle para que el volumen del líquido que se desaloja en la base existente entre los dos recipientes sea el mínimo necesario para marcar en el visor el estado de llenado de la bombona. 40 It is an object of the invention to report the volume of gas that a bottle 30 has by means of a simple visual indicator and without the need to weigh it subjectively by raising or stirring it. This is achieved with a container containing the bottle. This container is inside another container that contains it and is called the outer container. Between both cooperating vessels a liquid and an elastic element are arranged. The elastic element is necessary because the weight of the bottle is high and to make a meter with only liquid and the Archimedes principle, the volume of liquid would be very large and the meter unfeasible because of its large size. So the constant K of the spring is calculated so that the volume of the liquid that is dislodged in the existing base between the two containers is the minimum necessary to mark the filling status of the bottle in the viewfinder. 40

Es otro objeto de la invención que sea el propio líquido el que constituya el indicador sin necesidad de resortes que muevan flechas o de sensores de peso. El desplazamiento del líquido hacia arriba y hacia abajo, visto a través de un visor externo calibrado, presenta en todo momento la cantidad de gas que hay en la bombona. La información se presenta en tanto por ciento, correspondiendo el 100% a LLENO y el 0% a VACIO. 45 It is another object of the invention that it is the liquid itself that constitutes the indicator without the need for springs that move arrows or weight sensors. The displacement of the liquid up and down, seen through a calibrated external viewfinder, presents at all times the amount of gas in the bottle. The information is presented as a percentage, corresponding 100% to FULL and 0% to EMPTY. Four. Five

Y por último es otro objeto de la invención dotar a los recipientes cooperantes de una junta estanca que impida que el líquido pueda escapar de su interior durante el manipulado del medidor y de la bombona. Por motivo de transporte es posible que la And finally, it is another object of the invention to provide the cooperating vessels with a sealed gasket that prevents the liquid from escaping from its interior during the manipulation of the meter and the cylinder. For transportation reasons it is possible that the

bombona tenga que inclinarse o voltearse, un neopreno elástico evita la salida del líquido y a su vez permite el desplazamiento relativo entre los recipientes a medida que la bombona tiene menos gas y la distancia entre los recipientes se agranda. El desplazamiento entre los recipientes es vital para lograr una correcta lectura en el visor y con la finalidad de afianzar dicho desplazamiento se disponen unos topes de alineación 5 entre las paredes de los recipientes, ya que las paredes deben estar a la suficiente distancia para que el líquido fluya adecuadamente y lo suficientemente cerca para evitar desplazamientos relativos que dañen las paredes de los recipientes o incluso el muelle dispuesto en la base. bottle has to be tilted or turned, an elastic neoprene prevents the liquid from flowing out and in turn allows relative displacement between the containers as the cylinder has less gas and the distance between the containers is enlarged. The displacement between the containers is vital to achieve a correct reading in the viewfinder and in order to strengthen said displacement there are some alignment stops 5 between the walls of the containers, since the walls must be at a sufficient distance for the Liquid flow properly and close enough to avoid relative displacements that damage the walls of the containers or even the spring arranged at the base.

En relación al muelle, se ha comprobado que es más efectivo un único muelle en el 10 centro de la base que tres muelles distribuidos periféricamente como los mostrados en el estado de la técnica. Al utilizar un único muelle, este será más consistente y se calibrará mejor que si se usan varios. In relation to the spring, it has been proven that a single spring in the center of the base is more effective than three peripherally distributed springs such as those shown in the prior art. When using a single spring, it will be more consistent and will be better calibrated than if several are used.

Descripción detallada de la invención Detailed description of the invention

Tal y como se muestra en la figura 1 el dispositivo tiene los siguientes elementos: Dispone de un recipiente interior (2) el cual va a contener a la bombona (3). Dispone de un recipiente exterior (1), de mayor diámetro que el recipiente interior (2) y que a su vez 25 contiene al recipiente interior (2). De esta forma se define un cierto hueco o espacio perimetral (4) entre el recipiente interior (2) y el exterior (1) definido por la diferencia en sus diámetros y un hueco establecido entre sus bases inferiores (5). As shown in figure 1, the device has the following elements: It has an inner container (2) which will contain the bottle (3). It has an outer container (1), larger in diameter than the inner container (2) and which in turn contains the inner container (2). In this way a certain hole or perimeter space (4) is defined between the inner container (2) and the outer one (1) defined by the difference in its diameters and a gap established between its lower bases (5).

Con la finalidad de lograr un indicador visual entre el recipiente interior (2) y el recipiente exterior (1) se dispone a una cierta cantidad de fluido (6) en el hueco (4) existente entre 30 los recipientes. In order to achieve a visual indicator between the inner container (2) and the outer container (1) a certain amount of fluid (6) is disposed in the recess (4) between the 30 containers.

Por una parte el fluido (6) presenta un nivel inicial, cuando la bombona de gas (3) no está introducida en el recipiente interior (2) del dispositivo. Y por otra parte entre la base inferior del recipiente interior (2) y la base inferior del recipiente exterior (1) se disponen al menos un resorte (7) que se comprime en función del peso de la bombona (3) que se 35 introduce en el recipiente interior (2). De esta forma, cuando se introduce una bombona (3) en el recipiente interior (2) su peso comprime el muelle o resorte (7) de la base inferior de dicho recipiente interior (2) y por el principio de Arquímedes, el líquido o fluido (6) desalojado existente entre las bases de los recipientes, se eleva por el hueco (4) perimetral entre ambos recipientes elevándose su nivel. En función de la constante K del 40 muelle (7), de las distancias entre ambos recipientes y del tipo de fluido se calcula el volumen del mismo necesario para que el fluido (6) desalojado en el caso de una bombona llena y una vacía coincidan con nivel que marquen el 100% y 0% respectivamente en una escala dispuesta en un visor (8) del recipiente exterior (1). El resorte utilizado es un muelle (7) cuyos extremos se introducen en unos receptáculos que 45 On the one hand the fluid (6) has an initial level, when the gas cylinder (3) is not introduced into the inner container (2) of the device. And on the other hand, between the lower base of the inner container (2) and the lower base of the outer container (1) there is arranged at least one spring (7) which is compressed according to the weight of the cylinder (3) that is introduced in the inner container (2). In this way, when a bottle (3) is introduced into the inner container (2) its weight compresses the spring or spring (7) of the lower base of said inner container (2) and by the Archimedes principle, the liquid or fluid (6) dislodged between the bases of the containers, rises through the perimeter gap (4) between both containers, raising their level. Depending on the constant K of the 40 spring (7), the distances between both vessels and the type of fluid, the volume of the same is calculated so that the fluid (6) dislodged in the case of a full and empty cylinder match with level that mark 100% and 0% respectively on a scale arranged in a viewfinder (8) of the outer container (1). The spring used is a spring (7) whose ends are inserted into receptacles that 45

lo albergan evitando su desplazamiento lateral o desalineamiento. they house it avoiding its lateral displacement or misalignment.

El fluido (6) utilizado es preferentemente un anticongelante porque tiene color y es más fácil de visualizar que cualquier líquido transparente. También ayuda a que no se congele o empañe el visor (8). The fluid (6) used is preferably an antifreeze because it has color and is easier to visualize than any transparent liquid. It also helps to keep the viewfinder from freezing or fogging (8).

La distancia entre los recipientes es un factor importante en la invención. Si están muy 5 juntos el fluido (6) no circula entre ellos y las paredes del recipiente interno (2) y el externo (1) rozan y no se pueden desplazar adecuadamente. Para que esta distancia sea la apropiada se realiza el cálculo adecuado de la constante K del muelle (7) y se disponen en la pared interna del recipiente exterior (1) unos tacos de neopreno (9) que evitan el contacto entre las paredes de los recipientes y los mantienen siempre a la 10 distancia apropiada. The distance between the containers is an important factor in the invention. If they are very close together, the fluid (6) does not circulate between them and the walls of the inner container (2) and the outer one (1) rub and cannot move properly. For this distance to be appropriate, an adequate calculation of the constant K of the spring (7) is carried out and neoprene plugs (9) are arranged on the inner wall of the outer container (9) that prevent contact between the walls of the containers and always keep them at the appropriate distance.

En el detalle (a) de la figura 1 se muestra una banda de neopreno plástico (10) que actúa como elemento sellador entre ambos recipientes (1 y 2) evita la salida del fluido (6) hacia el exterior. La banda de neopreno plástico (10) se ancla a ambas paredes en la parte superior de los recipientes (1 y 2) y tiene una longitud tal que permite el desplazamiento 15 relativo entre las paredes cuando la bombona aligera su peso y los recipientes se separan (detalle b). In the detail (a) of Figure 1 a plastic neoprene band (10) is shown that acts as a sealing element between both containers (1 and 2) prevents the outflow of the fluid (6) to the outside. The plastic neoprene band (10) is anchored to both walls at the top of the containers (1 and 2) and has a length such that it allows relative displacement 15 between the walls when the cylinder lightens its weight and the containers are separated (detail b).

En la figura 2 se muestra una primera realización práctica donde el dispositivo dispone de un asa (11) para el transporte del mismo y de la bombona contenida en él. De la misma forma el dispositivo tiene una tapa (12) que se fija entre las paredes de ambos recipientes 20 (1 y 2) dejando un hueco para acceder a la válvula de emisión (13). Figure 2 shows a first practical embodiment where the device has a handle (11) for transporting the same and the bottle contained therein. In the same way the device has a lid (12) that is fixed between the walls of both vessels 20 (1 and 2) leaving a gap to access the emission valve (13).

En la figura 3 la bombona (3) es de mayores dimensiones y el dispositivo de medida sólo abarca la parte inferior. Para fijar el dispositivo a la bombona (3) se utilizan unas correas (14) que se aplican sobre un borde o un asa evitando que los recipientes (1 y 2) se desprendan de la citada bombona (3) al transportar el conjunto. 25 In figure 3 the cylinder (3) is larger and the measuring device only covers the lower part. To fix the device to the cylinder (3), belts (14) are used that are applied on an edge or a handle, preventing the containers (1 and 2) from detaching from said cylinder (3) when transporting the assembly. 25
