Carro de comprashopping cart
SECTOR DE LA TÉCNICATECHNIQUE SECTOR
La presente invención se refiere a un carro de la compra del tipo que comprende una estructura con al menos dos ruedas y una bolsa de tela o una cesta, flexible. Este carro tiene una estructura extremadamente ligera, manteniendo la resistencia.The present invention refers to a shopping trolley of the type that comprises a structure with at least two wheels and a flexible cloth bag or basket. This trolley has an extremely light structure, while maintaining resistance.
ESTADO DE LA TÉCNICASTATE OF THE ART
Se conoce en el estado de la técnica el uso de carros de compra formados por una estructura con ruedas que porta una bolsa. Frecuentemente la estructura es una "U” invertida realizada en aluminio. Este sistema es eficaz, pero el aluminio tiene un alto coste energético en su producción y manipulación y la estructura es relativamente pesada.The use of shopping carts made up of a structure with wheels that carry a bag is known in the state of the art. Frequently the structure is an inverted "U" made of aluminum. This system is effective, but aluminum has a high energy cost in its production and handling and the structure is relatively heavy.
El solicitante no conoce ningún carro que pueda ser considerado similar a la invención, en tanto no se conoce ningún carro con estructura de plástico, fabricada por medios de extrusión, suficientemente resistente.The applicant is not aware of any trolley that can be considered similar to the invention, as no trolley with a sufficiently resistant plastic structure, manufactured by means of extrusion, is known.
BREVE EXPLICACIÓN DE LA INVENCIÓNBRIEF EXPLANATION OF THE INVENTION
La invención consiste en un carro de compra, ligero, según las reivindicaciones. Sus diferentes realizaciones resuelven los problemas del estado de la técnica y proveen ventajas reseñables.The invention consists of a lightweight shopping cart, according to the claims. Its different embodiments solve the problems of the state of the art and provide notable advantages.
El carro de compra ligero está formado por una estructura con ruedas que porta una bolsa. La estructura está formada por barras huecas de plástico fabricadas por medios de extrusión, normalmente PVC, cuya sección tiene una dimensión mayor y una dimensión menor, y contiene travesaños paralelos a la dimensión menor, generalmente 2. La dimensión mayor aporta rigidez longitudinal a la estructura y los travesaños internos aseguran la rigidez transversal.The light shopping cart is formed by a structure with wheels that carries a bag. The structure is formed by hollow plastic bars manufactured by means of extrusion, normally PVC, whose section has a larger dimension and a smaller dimension, and contains crosspieces parallel to the smaller dimension, generally 2. The larger dimension provides longitudinal rigidity to the structure. and internal crossmembers ensure transversal rigidity.
La estructura puede formar un marco de varias formas, pero se prefiere que esté formada por barras rectas unidas por varas que atraviesan cada barra entre los travesaños. Esto optimiza la resistencia de la unión, dado que los travesaños sostienen las varas y la barra no necesita ser doblada.The structure can form a frame in various shapes, but it is preferred that it be formed by straight bars joined by rods that run through each bar between the crosspieces. This optimizes the strength of the joint, since the crosspieces support the rods and the bar does not need to be bent.
A su vez, las patas también pueden estar formadas por barras como la indicada. En ese caso, estarán articuladas a la estructura a través de ejes dispuestos entre los travesaños de las patas y de la estructura.In turn, the legs can also be formed by bars like the one indicated. In this case, they will be articulated to the structure through axes arranged between the crosspieces of the legs and of the structure.
Otras variantes se mostrarán en el resto de la memoria.Other variants will show up in the rest of the memory.

MODOS DE REALIZACIÓN DE LA INVENCIÓNMODES OF CARRYING OUT THE INVENTION
A continuación, se pasa a describir de manera breve un modo de realización de la invención, como ejemplo ilustrativo y no limitativo de ésta.An embodiment of the invention is briefly described below, as an illustrative and non-limiting example thereof.
En las figuras 1 y 2 se aprecia un ejemplo de realización formado por una estructura (1) y una bolsa (2). La estructura (1) está formada por una serie de barras (3) de plástico. La estructura (1) mostrada está formada por dos barras (3) unidas ente sí por varas (31) en diferentes puntos, y rematadas en sendas ruedas (4) y mangos (32) o asideros. De la estructura salen dos patas (5) articuladas, rematadas igualmente en ruedas (4). En el interior de la estructura (1) se dispone la bolsa (2), que tiene un cierre superior. La bolsa (2) está fijada a la estructura (1) y puede ser desmontable de ésta. Las varas (31) pueden ser los ejes de las ruedas (4).Figures 1 and 2 show an example of an embodiment made up of a structure (1) and a bag (2). The structure (1) is made up of a series of plastic bars (3). The structure (1) shown is made up of two bars (3) joined together by rods (31) at different points, and finished off with wheels (4) and handles (32) or handles. Two articulated legs (5) come out of the structure, likewise finished off with wheels (4). Inside the structure (1) the bag (2) is arranged, which has a top closure. The bag (2) is fixed to the structure (1) and can be detachable from it. The rods (31) can be the axles of the wheels (4).
La figura 3 muestra una sección de la barra (3) que forma la estructura (1). Se aprecia que la barra (3) es hueca y de sección ovalada, con una dimensión mayor aproximadamente doble de la dimensión menor. Dos travesaños (6) se disponen paralelos a la dirección menor, separados una distancia reducida (por ejemplo, 15-25% de la dimensión mayor). Estos travesaños (6) tienen dos funciones. Por un lado aportan resistencia mecánica y por otro definen un espacio central que puede ser atravesado por un vástago, tornillo, remache o cualquier otro elemento sin afectar a la resistencia estructural de la barra (3). Así, las patas (5) pueden articularse en ejes que pasan entre los travesaños (6). En la figura 3, se muestra el extremo de una vara (31) y cómo contacta con los travesaños (6) para aumentar la resistencia.Figure 3 shows a section of the bar (3) that forms the structure (1). It can be seen that the bar (3) is hollow and oval in section, with a larger dimension approximately twice the smaller dimension. Two crossbars (6) are arranged parallel to the minor direction, separated by a reduced distance (eg, 15-25% of the major dimension). These crossbars (6) have two functions. On the one hand they provide mechanical resistance and on the other they define a central space that can be traversed by a rod, screw, rivet or any other element without affecting the structural resistance of the bar (3). Thus, the legs (5) can be articulated in axes that pass between the crosspieces (6). Figure 3 shows the end of a rod (31) and how it contacts the crossbars (6) to increase resistance.
Las patas (5) igualmente pueden estar realizadas con barras (3) similares. Como se aprecia en las figuras, tanto las patas (5) como la estructura (1) están formadas por barras (3) rectas, de forma que la unión de ambas está realizada en ejes que atraviesan las barras (3) entre los travesaños (6).The legs (5) can also be made with similar bars (3). As can be seen in the figures, both the legs (5) and the structure (1) are formed by straight bars (3), so that the union of both is made in axes that cross the bars (3) between the crosspieces ( 6).
Es posible fijar una base (7) en la parte inferior de la bolsa (2), fijada a las barras (3), para ayudar a su sujeción.It is possible to fix a base (7) at the bottom of the bag (2), fixed to the bars (3), to help hold it.
La barra (3) puede ser de plástico, por ejemplo PVC, con lo que se pueden fabricar por extrusión. También puede ser utilizado polipropileno, polietileno, poliestireno, ABS y otros materiales cargados formulados especialmente para este uso. The bar (3) can be made of plastic, for example PVC, with which it can be manufactured by extrusion. Polypropylene, polyethylene, polystyrene, ABS and other filled materials specially formulated for this use can also be used.
