CARRO DE LA COMPRA SHOPPING CART

OBJETO DE LA INVENCIÓN OBJECT OF THE INVENTION

La invención, tal como expresa el enunciado de la presente memoria descriptiva, se refiere a un carro de la compra, el cual aporta innovadoras características estructurales y 5 constitutivas, que se describirán en detalle más adelante, que suponen una mejora del estado actual de la técnica dentro de su campo de aplicación. The invention, as expressed in the statement of the present specification, refers to a shopping cart, which provides innovative structural and constitutive characteristics, which will be described in detail below, which imply an improvement of the current state of the technique within its field of application.

Más en particular, el objeto de la invención se centra en un carro de la compra del tipo destinado a uso particular para incorporar y llevar de manera cómoda los productos, normalmente de alimentación, droguería, perfumería, etc. adquiridos en comercios o 10 supermercados, el cual presenta una configuración estructural diseñada para mejorar su utilidad y proporcionar ventajas frente a los carros de la compra convencionales existentes en el mercado, en especial enfocados a un más fácil acceso a su contenido y una mejor manejabilidad. More particularly, the object of the invention is centered on a shopping cart of the type intended for private use to incorporate and comfortably carry the products, usually food, drugstore, perfumery, etc. purchased in stores or 10 supermarkets, which has a structural configuration designed to improve its usefulness and provide advantages over conventional shopping carts in the market, especially focused on easier access to its content and better manageability.

CAMPO DE APLICACIÓN DE LA INVENCIÓN 15 FIELD OF APPLICATION OF THE INVENTION 15

El campo de aplicación de la presente invención se enmarca dentro del sector de la industria dedicada a la fabricación de accesorios para el hogar, centrándose particularmente en el ámbito de los carros o carritos de la compra para uso particular. The field of application of the present invention is part of the industry sector dedicated to the manufacture of home accessories, particularly focusing on the field of shopping carts or carts for private use.

ANTECEDENTES DE LA INVENCIÓN BACKGROUND OF THE INVENTION

En general, los carros de la compra existentes en el mercado suelen consistir en una bolsa o 20 cesta de configuración alta y estrecha, con una embocadura en su parte superior, la cual se incorpora sobre una estructura metálica de tubo con dos o cuatro ruedas que se puede arrastrar o empujar. In general, the shopping carts in the market usually consist of a bag or 20 basket with a high and narrow configuration, with a mouthpiece in its upper part, which is incorporated on a metal tube structure with two or four wheels that It can be dragged or pushed.

Uno de los principales inconvenientes de este tipo de carro es la dificultad, para ciertas personas, especialmente personas mayores, de acceder al fondo del carro para colocar o 25 extraer los productos. Además la manejabilidad del carro no es óptima, pues, aunque los hay con cuatro ruedas, éstas no son giratorias y ello dificulta su empuje y maniobrabilidad. One of the main drawbacks of this type of car is the difficulty, for certain people, especially older people, of accessing the bottom of the car to place or remove the products. In addition, the maneuverability of the car is not optimal, because, although there are four wheels, they are not swivel and this makes it difficult to push and maneuver.

Por otra parte, el segundo inconveniente esencial que tienen los carros existentes es el hecho de que en los supermercados hay que utilizar un carro para incorporar los productos a comprar y, tras pasar por caja, recolocarlos en el carro propio, debiendo, por tanto, 30 conseguir uno de los carros que proporciona el establecimiento, lo cual no siempre es fácil pues se agotan y/o hay que buscarlos en determinados puntos del centro comercial y, además, a menudo requiere de la utilización de monedas. Por último, tras la compra, se debe volver a colocar el carro del supermercado en su lugar. Esto, especialmente en centros de grandes dimensiones puede suponer un largo desplazamiento hasta dicho punto. 35 On the other hand, the second essential disadvantage that existing cars have is the fact that in supermarkets you have to use a car to incorporate the products to buy and, after going through the box, reposition them in your own car, therefore, you must 30 to get one of the cars provided by the establishment, which is not always easy because they are sold out and / or you have to look for them in certain points of the shopping center and, in addition, often requires the use of coins. Finally, after the purchase, the supermarket cart must be put back in its place. This, especially in large centers, can be a long displacement to that point. 35

En cualquier caso, es evidente que sería deseable poder contar con un carro de la compra del propio usuario que pueda servirle tanto para trasladar sus compras desde el establecimiento a su domicilio, como para usarlo dentro del propio establecimiento para ir llenándolo mientras recorre los pasillos, permitiendo, además, que sea apto para transportar dichos productos a pie por la calle o en el maletero del coche. 40 In any case, it is clear that it would be desirable to be able to have a shopping cart of the user himself who can serve both to transfer his purchases from the establishment to his home, and to use it within the establishment itself to go filling it while traveling the aisles, also allowing it to be suitable for transporting these products on foot in the street or in the trunk of the car. 40

Por otra parte y como referencia al estado actual de la técnica, cabe señalar que, si bien se conocen diferentes tipos de carros de la compra del tipo que aquí concierne, al menos por parte del solicitante, se desconoce la existencia de ninguno que presente unas características técnicas, estructurales y constitutivas semejantes a las que concretamente presenta el que aquí de preconiza, según se reivindica. 45 On the other hand and as a reference to the current state of the art, it should be noted that, although different types of shopping carts of the type that concern here are known, at least on the part of the applicant, the existence of none that presents some technical, structural and constitutive characteristics similar to those specifically presented here, as claimed. Four. Five
