Description

Recubrimiento para bastidores de carritos de compra.Coating for trolley frames purchase.

La presente invención tiene por objeto un cuerpo de recubrimiento para ser instalado sobre los bastidores tubulares que conforman algunos carritos de compra, particularmente en la zona de asido por el usuario, que tiene un reducido coste y que presenta una gran facilidad de montaje.The present invention aims at a body of coating to be installed on the tubular racks that make up some shopping carts, particularly in the user-seized area, which has a reduced cost and that It presents a great ease of assembly.

Existen distintos tipos de recubrimientos que se sitúan en los bastidores para los carritos de compra.There are different types of coatings that are They place on the racks for shopping carts.

Son conocidos recubrimientos formados por dos piezas que se adaptan a la estructura tubular del carrito, que mediante un conjunto de tetones pasantes o no por dicha estructura tubular, permiten la unión de dichas dos piezas conformando un único cuerpo, una vez montado.Coatings formed by two are known pieces that adapt to the tubular structure of the cart, which by means of a set of through pins or not by said structure tubular, allow the union of said two pieces forming a Single body, once mounted.

Sin embargo, dicho tipo de recubrimiento es caro por exigir la fabricación de dos piezas, y la aplicación de medios de unión, tales como una unión química por medio de adhesivos. Además, la unión de las dos piezas deja inevitablemente una grieta entre ambas piezas que llega a resultar incómodo para el usuario.However, such a coating is expensive. for demanding the manufacture of two pieces, and the application of means of union, such as a chemical union by means of adhesives. In addition, the union of the two pieces inevitably leaves a crack between both pieces that becomes uncomfortable for the Username.

Existe un tipo de recubrimiento que está formado por una pieza que se dispone y ajusta interiormente en el arco que forma el bastidor, y cuyo medio de sujeción consiste en unos tetones conformados en dicha pieza que se insertan en unos orificios practicados en la correspondiente zona del bastidor. Esta solución exige un mecanizado del tubo para realizarle los orificios, y la posición en la que queda dispuesto no resulta especialmente cómoda para el usuario.There is a type of coating that is formed by a piece that is arranged and adjusted internally in the arc that It forms the frame, and whose fastening means consists of shaped lugs in said piece that are inserted in some holes made in the corresponding area of the frame. This solution requires a machining of the tube to perform the holes, and the position in which it is arranged is not Especially comfortable for the user.

Otro tipo de recubrimiento consiste en un tubo flexible que se dispone envolviendo el tubo y que se coloca normalmente con la ayuda de inyección de aire comprimido. Si bien la comodidad de este recubrimiento es plenamente satisfactoria, el montaje resulta caro debido a las operaciones necesarias para su montaje.Another type of coating consists of a tube flexible that is arranged by wrapping the tube and placed normally with the help of compressed air injection. While The comfort of this coating is fully satisfactory, the assembly is expensive due to the operations necessary for its mounting.

La invención que se propone tiene por objeto un recubrimiento que envuelve casi totalmente el tubo que conforma el bastidor de un carrito de compra portador de una bolsa, está conformado en una sola pieza, no requiere mecanizado del bastidor y tiene un montaje muy sencillo.The proposed invention aims at a coating that almost completely envelops the tube that forms the frame of a shopping cart carrying a bag, is formed in one piece, does not require machining of the frame and It has a very simple assembly.

Detailed description of the invention

Consiste, pues, la presente invención en una pieza única de recubrimiento del tubo que conforma un bastidor de un carrito de compra, que comprende una parte superior correspondiente a la zona en la que se unen las dos ramas del bastidor, y una zona inferior, orientada hacia los extremos de dichas ramas del bastidor.The present invention therefore consists of a unique piece of tube covering that forms a frame of a shopping cart, which comprises a top corresponding to the area where the two branches of the frame, and a lower area, oriented towards the ends of said branches of the frame.

El recubrimiento 1 tiene una sección 2 de una porción tubular, es decir, de "C" más o menos cerrada en función de la presión que se deba ejercer en la sujeción. A más cerrada mayor esfuerzo en el cierre y mayor seguridad en la sujeción. Sin embargo, la fabricación resultará más compleja conforme la sección resulte más cerrada. Por el contrario, cuanto más abierta sea la "C" más facilidad de fabricación y montaje, pero menor seguridad en la sujeción. La presente invención cubre todo el espectro desde una "C" muy cerrada a una muy abierta. Normalmente dicha sección alcanzará aproximadamente la mitad de la sección del tubo, salvo en las zonas de pinzamiento 3 y 4, en las que la "C" será más cerrada. Denominamos zonas de pinzamiento a aquellas en las que el arco de la "C" es mayor de 180º.The coating 1 has a section 2 of a tubular portion, that is, of "C" more or less closed in function of the pressure that must be exerted in the restraint. To more closed greater effort in closing and greater security in the subjection. However, manufacturing will be more complex as the section becomes more closed. On the contrary, how much the "C" is more open, the easier to manufacture and assemble, but less security in the subjection. The present invention covers the whole spectrum from a "C" very closed to a very open. Normally said section will reach approximately half of the tube section, except in pinch zones 3 and 4, in the that the "C" will be more closed. We call pinch zones to those in which the arc of the "C" is greater than 180º.

Debido a la naturaleza del material plástico empleado, el pinzamiento es elástico, es decir, que cuando dicha pinza 3,4 envuelve al tubo 7 que constituye el bastidor se abre para acogerlo y posteriormente, una vez abrazado, vuelve elásticamente a la posición de reposo, impidiendo así que dicho tubo salga con facilidad.Due to the nature of the plastic material used, the grip is elastic, that is, when said clip 3.4 wraps around tube 7 which constitutes the frame opens to welcome him and later, once embraced, he returns elastically to the resting position, thus preventing said tube come out easily.

Los medios de pinzamiento estarán situados normalmente al menos en la parte superior, y preferentemente en su zona central, pero puede también haberlos en las ramas laterales, y preferentemente en los extremos inferiores de dichas ramas laterales.The clamping means will be located normally at least at the top, and preferably at its central area, but there may also be them in the lateral branches, and preferably at the lower ends of said branches lateral.

Conforme a la realización preferente representada los extremos inferiores de cada una de las dos ramas de la pieza que conforma el recubrimiento comprende sendos anillos 5, a través de los cuales se hace pasar el bastidor con sus extremos libres para el montaje de la pieza. Una vez pasados dichos extremos del bastidor por dichos anillos 5, se aproxima el recubrimiento hasta que alcance la posición de fijación permanente, momento en que a modo de articulación sobre los anillos, se fuerza el recubrimiento sobre el tubo del bastidor, produciendo el pinzamiento deseado. Salvo que se realiza una fuerza fuera de lo normal en la utilización del carro, la fijación resultará permanente.In accordance with the preferred embodiment represented the lower ends of each of the two branches of the piece that makes up the covering includes two rings 5, through which the frame is passed with its ends free for the assembly of the piece. Once these extremes have passed of the frame by said rings 5, the coating is approached until you reach the permanent fixation position, moment in that by way of articulation on the rings, the coating on the frame tube, producing the grip wanted. Unless an unusual force is performed in the use of the car, the fixation will be permanent.

Para dotar al conjunto de una adecuada solidez estructural, los extremos próximos a los de los anillos inferiores se encuentran unidos entre sí por medio de una riostra 6.To provide the set with adequate solidity structural, the ends close to those of the lower rings They are linked together by a brace 6.
