La invención, tal como expresa el enunciado de la presente memoria descriptiva, se refiere a una carretilla porta-bombonas para su carga y descarga de un vehículo aportando, a la función a que se destina, ventajas y características, que se describen en detalle más adelante, que suponen una mejora del estado actual de la técnica.The invention, as stated in the present specification, refers to a cart-holder for loading and unloading of a vehicle, contributing, to the function to which it is intended, advantages and characteristics, which are described in more detail. forward, which represent an improvement in the current state of the art.

Más concretamente, el objeto de la invención se centra en una carretilla manual de dos ruedas destinada a facilitar el reparto de bombonas de GLP (gas licuado de petróleo, comúnmente conocido como butano-propano), desde el camión en que se transportan al domicilio de los clientes, la cual presenta la particularidad de contar con una configuración estructural que incluye una base móvil accionable a través de un sistema hidráulico para efectuar sin esfuerzo el descenso de la bombona llena desde la plataforma de carga del camión en que se transportan, así como la elevación de la bombona vacía que se suele devolver al comprar la llena para colocarla igualmente sin esfuerzo en dicha plataforma, evitando con ello sobreesfuerzos que puedan perjudicar la salud de los repartidores de este tipo de bombonas.More specifically, the object of the invention is centered on a two-wheel manual truck designed to facilitate the distribution of LPG cylinders (liquefied petroleum gas, commonly known as butane-propane), from the truck in which they are transported to the domicile of customers, which has the peculiarity of having a structural configuration that includes a mobile base that can be operated through a hydraulic system to effortlessly lower the full cylinder from the loading platform of the truck in which they are transported, as well as the elevation of the empty cylinder that is usually returned when buying the full one to place it equally effortlessly on said platform, thereby avoiding over-efforts that may harm the health of the distributors of this type of bottles.

CAMPO DE APLICACIÓN DE LA INVENCIÓNFIELD OF APPLICATION OF THE INVENTION

El campo de aplicación de la presente invención se enmarca dentro del sector de la industria dedicada a la fabricación de carretillas manuales, centrándose particularmente en el ámbito de las conformadas por estructura con dos ruedas para empuje y/o arrastre de cargas manualmente.The field of application of the present invention is part of the industry sector dedicated to the manufacture of hand trucks, particularly focusing on the field of two-wheel structure for pushing and / or dragging loads manually.

ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION

Como es sabido, las bombonas de GLP, más conocidas como bombonas de butano o propano, aunque tienen diferentes tamaños, dado el material con que están hechas, suelen pesar bastante, incluso cuando están vacías. Ello hace que el movimiento de las mismas, especialmente por parte de los repartidores u operarios que las tienen que cargar y descargar continuamente de los camiones en que se distribuyen a los clientes, suponga un esfuerzo físico importante que, además, a menudo se traduce en lesiones indeseables debido a sobreesfuerzos y malas posturas adoptadas en los movimientos a realizar para proceder a su colocación en la carretilla de transporte.As is known, LPG cylinders, better known as butane or propane cylinders, although they have different sizes, given the material with which they are made, usually weigh a lot, even when they are empty. This makes their movement, especially by the distributors or operators who have to load and continuously unloading the trucks in which they are distributed to customers, supposes an important physical effort that, in addition, often translates into undesirable injuries due to overexertion and poor postures taken in the movements to be carried out to proceed to its placement in the truck transport.

De hecho, el movimiento que requiere mayor esfuerzo es, por una parte, la descarga de la bombona llena que se ha de entregar, para bajarla desde la plataforma de carga del camión en que se transportan este tipo de bombonas a la carretilla de mano con que se trasladan hasta el domicilio del cliente, y, por otra parte, la carga de la bombona vacía, que a cambio suele devolver el cliente, desde la carretilla con que se ha recogido del domicilio a la plataforma de carga del camión, ya que aún estando vacía, la bombona tiene un elevado peso.In fact, the movement that requires more effort is, on the one hand, the unloading of the full cylinder to be delivered, to lower it from the loading platform of the truck in which these types of cylinders are transported to the hand truck with that are moved to the customer's address, and, on the other hand, the empty cylinder's cargo, which in return is usually returned by the customer, from the truck with which it has been collected from the address to the truck's loading platform, since Even when empty, the bottle has a high weight.

El objetivo de la invención es, pues, proporcionar un medio para evitar que dichos movimientos deban realizarse cargando y descargando las bombonas a pulso a través del desarrollo de una carretilla mejorada para dotarla de tales medios.The objective of the invention is therefore to provide a means to prevent said movements from being carried out by loading and unloading the freehand cylinders through the development of an improved truck to provide it with such means.

Por otra parte, y como referencia al estado actual de la técnica, cabe señalar que, al menos por parte del solicitante, se desconoce la existencia de ninguna otra carretilla portabombonas que presente unas características técnicas, estructurales y constitutivas iguales o semejantes a las que presenta la que aquí se reivindica.On the other hand, and as a reference to the current state of the art, it should be noted that, at least on the part of the applicant, it is unknown the existence of any other bottle carrier that has technical, structural and constitutive characteristics equal or similar to those presented which is claimed here.

EXPLICACIÓN DE LA INVENCIÓNEXPLANATION OF THE INVENTION

La carretilla porta-bombonas para su carga y descarga de un vehículo que la invención propone permite alcanzar satisfactoriamente los objetivos anteriormente señalados, estando los detalles caracterizadores que lo hacen posible y que la distinguen convenientemente recogidos en las reivindicaciones finales que acompañan a la presente descripción.The cart-holder truck for loading and unloading a vehicle that the invention proposes allows to satisfactorily achieve the aforementioned objectives, the characterizing details making it possible and distinguishing it conveniently collected in the final claims that accompany the present description.

Más concretamente, tal como se ha apuntado anteriormente, lo que la invención propone es una carretilla manual, del tipo que de manera convencional cuenta con dos ruedas, una base inferior y una estructura tubular de dos pilares con respectivos mangos en su parte superior, la cual, con la finalidad de facilitar el transporte de bombonas de GLP, presenta la particularidad de contar con una configuración estructural mejorada que incluye una base móvil accionable a través de un sistema hidráulico para procurar su elevación y descenso, permitiendo efectuar sin esfuerzo el descenso de la bombona llena desde la plataforma de carga del camión en que se transporta, así como la elevación de la bombona vacía que se devuelve al comprar la llena para colocarla igualmente sin esfuerzo en dicha plataforma.More specifically, as noted above, what the invention proposes is a manual truck, of the type that conventionally has two wheels, a lower base and a two-pillar tubular structure with respective handles on its upper part, the which, in order to facilitate the transport of LPG cylinders, has the particularity of having an improved structural configuration that includes a mobile base that can be operated through a hydraulic system to ensure its elevation and descent, allowing to effortlessly lower the full cylinder from the loading platform of the truck in which it is transported, as well as the elevation of the empty cylinder that is returned when buying the full one to place it equally effortlessly on said platform.

Es objeto de la invención es, pues, incorporar en una carretilla tradicional de dos ruedas un sistema de elevación hidráulico, en concreto un amortiguador telescópico asociado a una base móvil que se desliza sobre unas guías incorporadas en los pilares de la estructura tubular de la carretilla, de manera que por medio de este amortiguador se consigue el descenso controlado de la bombona por el propio efecto de la gravedad desde el vehículo donde se transportan hasta el suelo. Una vez cambiada la botella, la vacía, una vez colocada en la base móvil, será impulsada por el amortiguador ascendiendo hasta la altura adecuada para poder colocarla en la plataforma de carga del vehículo que la transporta, valiéndose para ello del menor peso de la misma al encontrarse vacía de la carga de gas.The object of the invention is, therefore, to incorporate a hydraulic lifting system into a traditional two-wheeled truck, specifically a telescopic shock associated with a mobile base that slides on guides incorporated in the pillars of the tubular structure of the truck , so that through this shock absorber the controlled descent of the cylinder is achieved by the effect of gravity from the vehicle where they are transported to the ground. Once the bottle is changed, the empty one, once placed on the mobile base, will be driven by the shock absorber rising to the appropriate height to be able to place it on the loading platform of the vehicle that transports it, using the lowest weight of the same to be empty of the gas load.

Además, en la realización preferida, la carretilla cuenta también con sendos seguros en las partes superior e inferior del recorrido que efectúan las guías en que se desliza la base móvil, los cuales están controlados mediante un gatillo situado en el mango de la carretilla, a fin de poder controlar el descenso de las botellas llenas y el ascenso de las vacías, quedando anclada la base móvil al finalizar cada una de dichas operaciones.In addition, in the preferred embodiment, the truck also has two secure parts in the upper and lower parts of the path made by the guides on which the mobile base slides, which are controlled by a trigger located in the handle of the truck, a in order to control the descent of the full bottles and the rise of the empty ones, the mobile base being anchored at the end of each of these operations.

El elemento esencial del sistema es el amortiguador incorporado a la carretilla que debe soportar el peso de la botella (llena) y hacer posible que, al accionar el seguro, se produzca el descenso lento y seguro hacia el suelo para proseguir con el transporte manual sobre ruedas de la carga durante la distribución.The essential element of the system is the shock absorber incorporated into the truck that must support the weight of the bottle (full) and make it possible, when the safety is activated, the slow and safe descent to the ground occurs to continue with manual transport over Load wheels during distribution.

De igual forma, una vez efectuado el cambio de envases y colocada la botella (vacía), tras accionar el seguro inferior la botella subirá para permitir la posterior colocación de la misma en la plataforma de carga del vehículo.In the same way, once the packaging change has been carried out and the bottle (empty) is placed, after activating the lower insurance, the bottle will rise to allow its subsequent placement on the vehicle's loading platform.
