Description

CARRO DE SUPERMERCADOS SUPERMARKET CAR
En los supermercados y establecimientos semejantes, es convencional la disposición de carros al servicio de los clientes, para facilitar la recogida y el traslado de los productos que se adquieren.In supermarkets and similar establishments, the provision of cars at the service of customers is conventional, to facilitate the collection and transfer of products purchased.
Estos carros se han venido realizando generalmente por estructuras metálicas, a base de barras y varillas soldadas, solución ésta que recientemente se ha superado mediante construcciones en plástico. La presente invención hace mención a un carro de supermercado del tipo de los de plástico. Estos carros poseen una pared posterior de la cesta de carga en un montaje que permite su basculamiento respecto de una articulación superior, para permitir asi la inserción de un carro en otro durante el estacionado de los mismos; de manera que ocupen asi los carros un mínimo espacio. La cesta de carga de los carros requiere además una configuración en estrechamiento hacia la parte delantera, para que la inserción entre los carros sea posible, lo cual hace necesario que la pared posterior basculable de la cesta deba presentar un estrechamiento de su dimensión en anchura hacia abajo. Debido al estrechamiento de la pared posterior basculable de la cesta, se originan entre los bordes de dicha pared y las paredes laterales de la cesta unas aberturas inferiores, por las que pueden escapar objetos de la carga que se lleve alojada en el interior.These cars have been made generally by metal structures, based on bars and welded rods, this solution that has recently been overcome by plastic constructions. The present invention refers to a supermarket cart of the type of plastic. These cars have a rear wall of the cargo basket in an assembly that allows its tilting with respect to an upper joint, thus allowing the insertion of a car in another during the parking of the same; so that the cars occupy a minimum space. The loading cart of the carriages also requires a configuration in narrowing towards the front, so that the insertion between the carriages is possible, which makes it necessary for the rear tiltable wall of the basket to have a narrowing of its dimension in width towards down. Due to the narrowing of the tiltable rear wall of the basket, lower openings originate between the edges of said wall and the side walls of the basket, through which objects of the load that is housed inside can escape.
Para evitar estas aberturas se conoce ya una solución a base de unas piezas en escuadra, tal y como se describe en la Patente Española 9400444/7 de la solicitante.To avoid these openings, a solution based on square pieces is already known, as described in the Spanish Patent 9400444/7 of the applicant.
Por otro lado, en la mencionada pared posterior basculable de la cesta de los carros, suele incorporarse además un asiento para niños pequeños, formado por dos placas que forman un conjunto plegable y desplegable determinante del mencionado asiento. Estos asientos resultan en las realizaciones conocidas poco resistentes, debido a que el mantenimiento en la posición desplegada únicamente se determina por la retención de tope que establecen las dos partes que componen el asiento.On the other hand, in the aforementioned tiltable rear wall of the cart of the carts, a seat for small children, usually formed by two plates that form a folding and folding set determinant of the mentioned seat. These seats result in poorly known known embodiments, because maintenance in the deployed position is only determined by the stop retention established by the two parts that make up the seat.
En otro orden, nos encontramos con que se han hecho diversos intentos para disponer publicidad en estos carros, pero ninguno de estos intentos ha dado un resultado final satisfactorio.In another order, we find that various attempts have been made to arrange publicity in these cars, but none of these attempts have given a satisfactory end result.
En efecto, en el caso de los carros metálicos, no es posible colgar publicidad por fuera de las paredes laterales de la cesta, porque ello impide la penetración de una cesta dentro de otra, cuando se dispone un carro detrás de otro en su almacenaje.Indeed, in the case of metal cars, it is not possible to hang advertising outside the side walls of the basket, because this prevents the penetration of one basket into another, when a car is placed behind another in its storage.
Ello obliga a que en estos carros metálicos sólo puede ir la publicidad en el frente de su cesta, lo cual no es suciente y por lo tanto esta solución no ha sido aceptada. En el caso de los carros de plástico los carteles de publicidad se colocan de forma sobrepuesta en las paredes de las cestas, sujetándose por cualquier medio adecuado. Esto determina una disposición sobresaliente respecto de las mencionadas paredes, dando lugar a la posibilidad de enganches en el manejo de los carros y a roces en la inserción entre ellos, sufriendo por su parte los carteles publicitarios un rápido deterioro; por lo que tampoco esta solución ha sido debidamente aceptada. De acuerdo con la presente invención se propone un nuevo carro de los del tipo indicado, el cual se halla desarrollado según una realización que aporta características constructivas y funcionales uy ventajosas, solucionando eficazmente todos los mencionados problemas e inconvenientes de los carros de ese tipo actualmente conocidos .This forces that in these metallic cars only the advertising in the front of their basket can go, which is not enough and therefore this solution has not been accepted. In the case of plastic cars, the advertising posters are placed superimposed on the walls of the baskets, held by any suitable means. This determines an outstanding disposition with respect to the mentioned walls, giving rise to the possibility of hooks in the handling of the cars and friction in the insertion between them, the advertising posters suffering a rapid deterioration; Therefore, this solution has not been properly accepted. In accordance with the present invention, a new car of the type indicated is proposed, which is developed according to an embodiment that provides constructive and functional and advantageous characteristics, effectively solving all the aforementioned problems and disadvantages of carriages. That guy currently known.
Este carro objeto de la invención, se constituye por un cuerpo monopieza de plástico que define la cesta de carga y la base soporte a la que se acoplan las ruedas de apoyo, comprendiendo la cesta igualmente una pared posterior basculable, con la particularidad de que inferiormente entre dicha pared bascul ble y las paredes laterales se incorporan unas plaquetas que cierran los huecos inferiores resultantes entre la mencionada pared basculable y las paredes laterales, disponiéndose dichas plaquetas en un montaje abisagrado que permite su abatimiento contra las paredes laterales para posibilitar la inserción de los carros, con tendencia sin embargo a autoposicionarse esas plaquetas en la posición de cierre de los mencionados huecos.This carriage object of the invention is constituted by a single-piece plastic body that defines the loading basket and the support base to which the support wheels are coupled, the basket also comprising a tiltable rear wall, with the peculiarity that inferiorly between said tiltable wall and the side walls are incorporated platelets that close the resulting lower gaps between said mentioned tiltable wall and the side walls, said platelets being arranged in a hinged assembly that allows its folding against the side walls to enable the insertion of the cars, with a tendency however to self-position those platelets in the closed position of the mentioned holes.
En este carro objeto de la invención, las paredes del contorno de la cesta quedan definidas además con unas nervaduras sobresalientes hacia el exterior. Gracias a estas nervaduras las paredes de la cesta adquieren la consistencia necesaria, resultando por el interior una superficie totalmente lisa, mientras que exteriormente se determinan zonas remetidas para la colocación de carteles de publicidad en una disposición protegida, que no recibe golpes al insertarse la cesta de un carro dentro de la cesta de otro carro.In this carriage object of the invention, the contour walls of the basket are further defined with protruding ribs towards the outside. Thanks to these ribs, the walls of the basket acquire the necessary consistency, resulting in a completely smooth surface on the inside, while externally recessed areas are determined for the placement of advertising posters in a protected arrangement, which does not receive bumps when the basket is inserted of a car inside the basket of another car.
En la parte superior de las paredes laterales de la cesta se han previsto sendos entrantes en forma de escalón, en los cuales se alojan unas alas laterales de la placa de respaldo del asiento para los niños determinándose así unos topes que mantienen establemente al respaldo del asiento para los niños en la posición de uso del mismo.In the upper part of the side walls of the basket, two step-shaped recesses are provided, in which lateral wings of the seat back plate for children are housed, thus determining stops that keep the back of the seat stably for children in the position of use of it.
La base de soporte del carro se halla provista con una prolongación posterior que rebasa el plano vertical de la trasera de la cesta, incorporándose las ruedas de ] apoyo posteriores en esa prolongación, con lo cual se logra una disposición que reduce la posibilidad de vuelco del carro, hacia su parte posterior.The carriage support base is provided with a rear extension that exceeds the vertical plane of the rear of the basket, incorporating the wheels of ] support later in this extension, which achieves a provision that reduces the possibility of overturning the car, towards its rear.
Las ruedas de apoyo del carro se montan mediante un dispositivo de compresión de un casquillo elástico que al expansionarse queda comprimido, permitiendo un montaje rápido y a la vez seguro de esas ruedas con respecto a la base del carro; resultando posible el desmontaje con igual facilidad. Q Por todo ello, este carro objeto de la invención resulta con unas características muy ventajosas, con respecto a los carros conocidos del mismo tipo.The support wheels of the carriage are mounted by means of a compression device of an elastic bushing which, when expanded, is compressed, allowing a quick and safe assembly of those wheels with respect to the carriage base; resulting in disassembly with equal ease. Q For all these reasons, this car which is the object of the invention has very advantageous characteristics, with respect to known cars of the same type.

El objeto de la invención es un carro de los que se disponen en supermercados y establecimientos similares . De acuerdo con la presente invención este carro se constituye por un cuerpo monopieza de plástico que incluye la cesta (1) de carga y una base portante (2) en la que se acoplan las correspondientes ruedas de apoyo (3) para el desplazamiento del carro.The object of the invention is a car available in supermarkets and similar establishments. In accordance with the present invention, this car is constituted by a single-piece plastic body that includes the load basket (1) and a supporting base (2) in which the corresponding support wheels (3) for the carriage movement are coupled .
Como en los carros convencionales de este tipo, la cesta (1) de carga comprende una pared posterior (4) dispuesta en montaje basculable respecto de una articulación superior (5) , para posibilitar así la inserción de unos carros en otros en el estacionamiento de los mismos. Para ello, la cesta (1) determina también una configuración que se va estrechando hacia la parte delantera, con el fin de que resulte posible la referida inserción de los carros .As in conventional cars of this type, the cargo basket (1) comprises a rear wall (4) arranged in a swiveling assembly with respect to an upper joint (5), thus enabling the insertion of some cars in others in the parking lot. the same. For this, the basket (1) also determines a configuration that narrows towards the front, in order to make possible the aforementioned insertion of the carriages.
Esta configuración de la cesta (1) condiciona a que la pared basculable posterior (4) deba presentar una forma en estrechamiento hacia abajo, para que su dimensión en anchura le permita bascular por el interior de la cesta (1) , cuando se inserta la cesta (1) de un carro dentro de la cesta (1) de otro.This configuration of the basket (1) determines that the rear tilting wall (4) must have a narrowed down shape, so that its Dimension in width allows you to swing around the inside of the basket (1), when you insert the basket (1) of a car into the basket (1) of another.
Ello da lugar a que inferiormente entre la mencionada pared basculante posterior (4) y las paredes laterales de la cesta (1) queden unos huecos (6) , por los que pueden caer los productos de la carga que se alojen en el interior de la cesta (1) .This results in that inferiorly between the aforementioned rear tilting wall (4) and the side walls of the basket (1) there are some gaps (6), through which the products of the load that are housed inside the interior can fall. basket (1).
Para solucionar este problema, en el carro objeto de la presente invención se incorporan unas plaquetasTo solve this problem, platelets are incorporated in the carriage of the present invention
(7) coincidiendo en una cierta altura con los mencionados huecos (6) , de forma que éstos quedan así cubiertos en su parte de mayor anchura, evitando que los objetos de la carga puedan salirse a través de dichos huecos (6) .(7) coinciding at a certain height with the mentioned recesses (6), so that they are thus covered in their part of greater width, preventing the objects of the load from being able to exit through said recesses (6).
Esas plaquetas (7) se sujetan a través de un montaje abisagrado. Para ello existe una conformación cilindrica (8) lateralmente abierta que dichas plaquetasThese platelets (7) are fastened through a hinged assembly. For this there is a laterally open cylindrical conformation (8) that said platelets
(7) poseen en un borde; de manera que esta conformación cilindrica (8) encaja sobre un correspondiente vastago(7) own on an edge; so that this cylindrical conformation (8) fits on a corresponding rod
(9) de sujeción configurado en el cuerpo monopieza del carro.(9) clamping set on the car's one-piece body.
La mencionada conformación cilindrica (8) de las plaquetas (7) queda definida con un chaflán (10) en la parte inferior, mientras que los vastagos (9) para el montaje de esas plaquetas (7) se definen entre un par de lengüetas (11) y (12) , quedando la inferior (12) en posición inclinada, preferentemente con la misma inclinación del chaflán (10) de las conformaciones cilindricas (8) de las plaquetas (7) .The aforementioned cylindrical conformation (8) of the platelets (7) is defined with a chamfer (10) at the bottom, while the rods (9) for mounting these platelets (7) are defined between a pair of tabs ( 11) and (12), the lower one (12) being in an inclined position, preferably with the same chamfer inclination (10) of the cylindrical conformations (8) of the platelets (7).
En tales condiciones, dichas plaquetas (7) tienden a posicionarse en el montaje en una situación estable determinada por la coincidencia de la inclinación del chaflán (10) de las conformaciones (8) con la lengüeta inclinada inferior (12) de los vastagos (9) , según se - 7 -Under such conditions, said platelets (7) tend to be positioned in the assembly in a stable situation determined by the coincidence of the chamfer inclination (10) of the conformations (8) with the lower inclined tongue (12) of the stems (9). ) , is according - 7 -
representa en la figura 11; situación esa que se halla prevista para que las plaquetas (7) queden cubriendo los huecos (6) en la función para la que están destinadas, es decir para evitar que por los huecos (6) se salgandepicted in figure 11; situation that is planned so that the platelets (7) are covering the holes (6) in the function for which they are intended, that is to avoid that the holes (6) leave
5 los productos alojados dentro de la cesta (1) .5 products housed in the basket (1).
Desde esa posición de cierre de las mencionadas plaquetas (7) , éstas pueden bascular hacia las paredes laterales de la cesta (1) , quedando así retiradas; de manera que no impiden ni dificultan la inserción entre Q las cestas (1)" de los carros, con la particularidad de que gracias a los planos inclinados del chaflán (10) y de la lengüeta (12) al producirse el giro de dichas plaquetas (7) éstas se ven obligadas a ascender, según puede observarse en la figura 12, quedando así las 5 plaquetas (7) en una posición inestable que hace que las mencionada plaquetas (7) tiendan a volver por sí mismas a la posición estable inferior de cierre cuando quedan libres .From that closed position of said platelets (7), they can swing towards the side walls of the basket (1), thus being removed; so that they do not prevent or hinder the insertion between Q the baskets (1) " of the carriages, with the particularity that thanks to the inclined planes of the chamfer (10) and of the tongue (12) when the rotation of said platelets occurs (7) these are forced to ascend, as can be seen in Figure 12, thus leaving the 5 platelets (7) in an unstable position that makes the said platelets (7) tend to return themselves to the lower stable position of closing when they are free.
De esta forma, cuando se saca la cesta (1) de un 0 carro del interior de la cesta (1) del carro delantero, automáticamente las plaquetas (7) tienden a volver por sí mismas a la posición de cierre, asegurando así siempre el cierre de los huecos (6).Thus, when the basket (1) of a 0 carriage is removed from the inside of the basket (1) of the front carriage, the platelets (7) automatically return to the closed position by themselves, thus always ensuring the closing of the gaps (6).
Las paredes del contorno de la cesta (1) por los laterales y el frente, quedan definidas con unas 5 nervaduras (13) que sobresalen hacia el exterior. Gracias a estas nervaduras (13) el contorno de la cesta (1) adquiere una consistencia adecuada, resultando por otra parte las paredes con un plano de fondo liso y un plano exterior en relieve definido por las crestas de 0 las nervaduras (13) , lo cual permite la determinación de zonas remetidas (14) por dicha parte exterior, para la colocación en estas zonas remetidas (14) de carteles publicitarios. De esta forma al encajar una cesta (1) ^ r dentro de la cesta (1) de otro carro, los carteles publicitarios quedan a salvo de roces , debido a su situación remetida con respecto al plano exterior que definen las nervaduras (13) ; en tanto que la superficie interna de las paredes resulta perfectamente lisa, permitiendo la inserción de una cesta (1) en la cestaThe contour walls of the basket (1) by the sides and the front, are defined with about 5 ribs (13) protruding outwards. Thanks to these ribs (13), the contour of the basket (1) acquires an adequate consistency, resulting in the walls with a smooth bottom plane and an outer relief plane defined by the ridges of the ribs (13), which allows the determination of areas tucked in (14) by said outer part, for the placement in these areas tucked (14) of advertising posters. In this way, by placing a basket (1) ^ r inside the basket (1) of another car, the posters advertising are safe from friction, due to their location with respect to the outer plane defined by the ribs (13); while the inner surface of the walls is perfectly smooth, allowing the insertion of a basket (1) in the basket
(1) del carro de delante.(1) of the car in front.
En cada zona remetida (14) destinada para la incorporación de publicidad, existe, al menos un orificio (15) pasante hasta el interior de la cesta (1) , a través del cual resulta posible la actuación con cualquier elemento punzante para ejercer un empuje hacia afuera sobre los carteles de publicidad que se hallen colocados, permitiendo iniciar fácilmente la extracción de dichos carteles para la retirada de los mismos. La superficie lisa de las paredes por el interior de la cesta (1) , permite además que sobre la pared extrema frontal resulten incorporables así mismo carteles de publicidad en la cara interna, con el fin de que éstos queden a la vista de la persona que lleva el carro .In each enclosed area (14) intended for the incorporation of advertising, there is at least one hole (15) through to the inside of the basket (1), through which it is possible to act with any sharp element to exert a thrust. outwards on the advertising posters that are placed, allowing to easily start the extraction of said posters for their removal. The smooth surface of the walls inside the basket (1) also allows advertising posters on the inner side to be incorporated on the front end wall, so that they are visible to the person who Take the car
En la pared basculable posterior (4) se incorpora un asiento para niños formado por sendas placas (17) yIn the rear tiltable wall (4) a child seat consisting of two plates (17) and
(18) relacionadas entre sí mediante un acoplamiento deslizante y articuladas ambas sobre la mencionada pared (4) ; en la determinación de un conjunto plegable y desplegable entre sendas posiciones de recogida y de uso. Una de las placas (17) constituye la base de asiento, en tanto que la otra (18) se constituye como respaldo . La referida placa de respaldo (18) tiene unas aletas laterales (19) en la parte superior. Estas aletas(18) related to each other by means of a sliding coupling and articulated both on said wall (4); in the determination of a folding and folding set between two collection and use positions. One of the plates (17) constitutes the seat base, while the other (18) is constituted as a backrest. The aforementioned back plate (18) has lateral fins (19) in the upper part. These fins
(19) se corresponden con unos remetidos (20) en forma de escalones definidos por la parte interior de las paredes laterales de la cesta (1) , en la determinación con ello de unos topes que permiten un firme apoyo del respaldo (18) en la posición desplegada del asiento, manteniéndose así estable dicha posición, tal y como se observa en la figura 13.(19) correspond to recesses (20) in the form of steps defined by the inside of the side walls of the basket (1), in this way determining stops that allow a firm support of the backrest (18) in the deployed position of the seat, thus maintaining said position, as seen in Figure 13.
La incorporación de las ruedas (3) en la base (2) del carro, se establece mediante un acoplamiento, formado por un vastago (21) con cabeza ensanchada (22) en uno de los extremos y rosca para la incorporación de una tuerca (23) en el otro extremo, pasando dicho vastago (21) axialmente por un casquillo cilindrico (24) de material elástico y a través del correspondiente soporte (25) de la respectiva rueda (3) .The incorporation of the wheels (3) in the base (2) of the carriage is established by means of a coupling, formed by a rod (21) with a widened head (22) at one end and thread for the incorporation of a nut ( 23) at the other end, said rod (21) passing axially through a cylindrical bushing (24) of elastic material and through the corresponding support (25) of the respective wheel (3).
De esta forma, para efectuar el montaje de las ruedas (3) en la base (2) del carro, solamente es necesario introducir el conjunto del casquillo (24) con el vastago (21) axialmente incorporado a través de él, en un alojamiento (26) definido en la base (2) , según representa la figura 14 , para una vez efectuada la introducción apretar la tuerca (23) . Al apretar la tuerca (23) se tira del vastago (21) provocando un ensanchamiento del casquillo (24) que se aprieta contra la pared del alojamiento (26) , lo que asegura la sujeción de la rueda (3) .Thus, to mount the wheels (3) on the base (2) of the car, it is only necessary to insert the bushing assembly (24) with the rod (21) axially incorporated through it, in a housing (26) defined in the base (2), as shown in figure 14, for once the insertion is made, tighten the nut (23). When tightening the nut (23), the rod (21) is pulled causing a widening of the bushing (24) that is pressed against the wall of the housing (26), which ensures that the wheel is secured (3).
El desmontaje resulta efectuable a su vez con la misma facilidad, ya que sólo es necesario aflojar la tuerca (23) , de manera que al dejar de comprimir el vastago (21) axialmente al casquillo elástico (24) , éste recupera su forma original dejando de presionar contra la pared del alojamiento (26) . Esto supone como consecuencia la posibilidad de sustituir muy fácilmente cualquiera de las ruedas (3) del carro, cuando así sea necesario.The disassembly is effective in turn with the same ease, since it is only necessary to loosen the nut (23), so that by stopping compressing the rod (21) axially to the elastic bushing (24), it recovers its original shape leaving to press against the wall of the housing (26). This results in the possibility of replacing any of the wheels (3) of the car very easily, when necessary.
De acuerdo con una particularidad de la invención, la base (2) del carro se conforma con una prolongación posterior (27) que rebasa el plano vertical posterior de la cesta (1) , yendo las ruedas de apoyo (3) de esa parte trasera incorporadas en la mencionada prolongación (27) , lo cual determina una ampliación del espacio longitudinal entre los apoyos del carro, quedando el centro de gravedad a una mayor distancia de dichos apoyos , con lo que se consigue una mayor estabilidad del carro, reduciéndose la posibilidad de vuelco por el esfuerzo del empuje ejercido sobre el manillar (16) , por parte del usuario del carro, el cual en muchos casos efectúa un empuje hacia abajo que tiende a provocar el vuelco del carro hacia atrás. In accordance with a particular feature of the invention, the base (2) of the carriage is formed by a rear extension (27) that goes beyond the rear vertical plane of the basket (1), the support wheels (3) leaving that part rear incorporated in the mentioned extension (27), which determines an extension of the longitudinal space between the supports of the car, leaving the center of gravity at a greater distance from said supports, thereby achieving greater stability of the car, reducing the possibility of overturning by the effort of the thrust exerted on the handlebar (16), by the user of the car, which in many cases makes a downward push that tends to cause the car to overturn.
