También se contempla la posibilidad de montar dos dispositivos en el mismo eje transversal de la plataforma del carro compartiendo la misma palanca, con el pedal en el 15 and an open grape-shaped plate with a torsion and interlocking spring, actuated by the lever, whose base is a vertical support rod with a rubber stop and a damping spring, which is the one that exerts the braking action against the ground when the operator presses the pedal. It also contemplates the possibility of mounting two devices on the same transverse axis of the carriage platform sharing the same lever, with the pedal in the

20 centro de ambos, todo ello según se describe en detalle más adelante. 20 center of both, all as described in detail below.

En una u otra variante, la invención tiene como ventaja principal el dotar de un sistema de frenado a unos carros ligeros que normalmente no llevan freno, sin menoscabo de su funcionalidad. In one or another variant, the invention has as its main advantage the provision of a braking system to light cars that normally do not have a brake, without compromising their functionality.

CAMPO TÉCNICO.-TECHNICAL FIELD.-

El campo técnico en que se encuadra la invención es el de los mecanismos de frenado y dispositivos de inmovilización adaptables a vehículos propulsados a mano. The technical field in which the invention is framed is that of braking mechanisms and immobilization devices adaptable to hand-propelled vehicles.

ESTADO DE LA TÉCNICA.-STATE OF THE TECHNIQUE.-

Los carros de manutención en sistema de producción en cadena son carros de pequeño tamaño que sirven para suministrar a los diferentes puestos de trabajo de la cadena Maintenance trucks in a chain production system are small cars that serve to supply the different jobs in the chain

35 aquellos componentes que se precisan para el montaje o ensamblaje de los productos finales. En el sector de la automoción, por ejemplo, son muy utilizados en las líneas de ensamblaje de los vehículos, para el suministro de los escapes, manillas, manguitos, piezas metálicas, o accesorios plásticos, entre otros componentes. 35 those components that are required for the assembly or assembly of the final products. In the automotive sector, for example, they are widely used in vehicle assembly lines, for the supply of exhausts, handles, sleeves, metal parts, or plastic accessories, among other components.

Dadas sus características estructurales y funcionales, estos carros de manutención no Given their structural and functional characteristics, these maintenance cars do not

5 disponen normalmente de freno alguno, sino que como se ha dicho, son conducidos por los operarios, desplazándolos y deteniéndolos por sus propios medios. Esta forma de trabajo es evidente que no está exenta de riesgos e inconvenientes, derivados de atropellos, vuelcos, o descontrol en estado de parados. Sin embargo, la solución de dotarles de un sistema de freno no es fácil, debido a su ligereza y a la poca distancia entre la base y el suelo; de hecho 5 normally have some brake, but as stated, they are driven by the operators, moving and stopping them by their own means. This form of work is evident that it is not free of risks and inconveniences, derived from abuses, overturns, or uncontrolled state of unemployed. However, the solution of providing them with a brake system is not easy, due to its lightness and the short distance between the base and the ground; in fact

10 muchos de los sistemas convencionales de frenado de carros de la compra o portaequipajes en general no son aquí aplicables, y otros resultan inadecuados o incómodos para el operario. 10 many of the conventional braking systems for shopping carts or luggage carriers in general are not applicable here, and others are inadequate or uncomfortable for the operator.

Con el freno en cuestión se solventa el referido problema de los carros de logística y With the brake in question, the aforementioned problem of logistics cars and

15 manutención, ya que es un pequeño dispositivo adaptable a la parte inferior de la plataforma del carro, que se acciona con el pie, de modo que no entorpece el movimiento y funcionalidad del mismo, y además cuenta con un mecanismo de enclavamiento que permite al operario abandonar momentáneamente el carro sin riesgo de que salga rodando. 15 maintenance, since it is a small device adaptable to the lower part of the carriage platform, which is operated with the foot, so that it does not hinder the movement and functionality of the same, and also has an interlocking mechanism that allows the Operator leave the car momentarily without risk of rolling.

20 El dispositivo se considera de invención respecto a los sistemas y medios de freno habitualmente utilizados en los referidos carros impulsados a mano, teniendo en cuenta que en el desarrollo del producto no se ha adaptado un sistema de freno utilizado o concebido para carros de la compra, de mercancías o portaequipajes, a un carro de logística o manutención de las señaladas características, sino que se ha diseñado un dispositivo The device is considered to be an invention with respect to the brake systems and means commonly used in the aforementioned hand-driven cars, taking into account that in the development of the product a brake system used or designed for shopping carts has not been adapted , from merchandise or luggage carrier, to a logistics or maintenance cart of the aforementioned characteristics, but a device has been designed

25 completamente nuevo para este tipo de carros, y para otros cuya estructura lo permita. 25 completely new for this type of car, and for others whose structure allows it.

En efecto, dentro del estado de la técnica relativo a los mecanismos de frenado e inmovilización para vehículos propulsados a mano, el más próximo al dispositivo de freno en cuestión lo constituyen aquellos mecanismos en los que el freno se acciona con el pie, entre 30 los que son muy conocidas las piezas en forma de pestaña montadas sobre el eje de una de las ruedas, que al pisarlas descienden y bloquean el giro. Una búsqueda en la base de datos Invenes de la OEPM sobre patentes relativas a esta cuestión técnica, de frenos para carros accionables con el pie, revela la existencia de únicamente tres documentos, en dos de los cuales, el modelo de utilidad ES1037445U “Freno de doble acción simplificado” y la 35 patente europea para España ES2038360T3 “Mecanismo de freno para ruedas giratorias”, el freno actúa directamente sobre las ruedas, presionándolas para detener e impedir su giro. Sólo Indeed, within the state of the art relating to braking and immobilization mechanisms for hand-propelled vehicles, those closest to the brake device in question are those mechanisms in which the brake is operated with the foot, between 30 that the tab-shaped pieces mounted on the axle of one of the wheels are well known, which, when stepped on, descend and block the turn. A search in the SPTO's Youth database on patents related to this technical issue of brakes for foot-operated cars reveals the existence of only three documents, in two of which, the utility model ES1037445U “Brake of Simplified double action ”and the European patent for Spain ES2038360T3“ Brake mechanism for rotating wheels ”, the brake acts directly on the wheels, pressing them to stop and prevent its rotation. Alone

el tercer documento de los encontrados, la patente española ES2291082-B1 “Freno para carros de carga, palets y similares”, divulga un sistema de freno accionado con el pie y cuyo mecanismo de frenado se produce por fricción de un tope contra el suelo, de similar operativa que la presente invención. Sin embargo, es un sistema esencialmente distinto, ya the third document found, the Spanish patent ES2291082-B1 "Brake for cargo cars, pallets and the like", discloses a brake system operated with the foot and whose braking mechanism is produced by friction of a stop against the ground, similar in operation as the present invention. However, it is an essentially different system, since

5 que, entre otras diferencias, la articulación que permite descender al tope para que contacte con el suelo responde a otro tipo de estructura. 5 that, among other differences, the articulation that allows to descend to the top so that it contacts the ground responds to another type of structure.

Por tanto, tampoco se conocen, al menos con efectos en España, patentes que anticipen un sistema de frenado para carros de manutención similar al dispositivo preconizado. Therefore, patents that anticipate a braking system for handling cars similar to the recommended device are not known, at least with effects in Spain.

LA INVENCION.-THE INVENTION.-

El freno en cuestión, concebido como primera utilidad para su acoplamiento fijo y estable en los carros de manutención en líneas de producción en cadena descritos, consiste en un 15 dispositivo mecánico de pequeño tamaño fijado a la parte inferior de la plataforma de este tipo de carros, constituido por una estructura soporte formada por una placa horizontal con taladros para su fijación al carro mediante tornillos pasantes con tuerca, y dos lados laterales simétricos en forma de escuadra, entre los que va montada, por la parte entre vértices de catetos verticales, una placa en forma de uve abierta con un vástago transversal 20 roscado con muelle de torsión y enclavamiento en uno de sus extremos, por el que va unida a la estructura soporte por sendos taladros practicados en dichos vértices de catetos verticales, mediante tuercas de apriete, y un vástago vertical de apoyo con tope de goma y muelle de compresión en el otro extremo; y por la parte entre vértices de catetos horizontales de escuadras laterales, una palanca con dos vástagos transversales roscados, The brake in question, conceived as the first utility for its fixed and stable coupling in the handling trolleys in production lines described, consists of a small mechanical device fixed to the bottom of the platform of this type of carriage , constituted by a support structure formed by a horizontal plate with holes for its attachment to the carriage by means of bolt-through bolts, and two symmetrical lateral sides in the shape of a square, between which it is mounted, by the part between vertices of vertical legs, a Open-shaped plate with a transverse rod 20 threaded with a torsion spring and interlocking at one of its ends, whereby it is attached to the support structure by two drills made in said vertices of vertical legs, by means of tightening nuts, and a vertical support rod with rubber stop and compression spring at the other end; and for the part between vertices of horizontal legs of lateral squares, a lever with two threaded transverse stems,

25 uno superior por el que va unida a la estructura soporte por sendos taladros practicados en dichos vértices de catetos horizontales, mediante tuercas de apriete, y otro inferior por el que va unida a la placa en forma de uve por sendos ojales practicados a ambos lados de su eje de inflexión, mediante tuercas de apriete, y con una pedalera de accionamiento en su extremo. 25 a superior one by which it is attached to the support structure by two drills made in said vertices of horizontal legs, by means of tightening nuts, and a lower one by which it is attached to the plate in the form of a grape by two eyelets made on both sides of its axis of inflection, by means of nuts of tightening, and with a pedal of drive in its end.

30 De esta manera, el freno se acciona cuando el operario pisa la pedalera, desciende la palanca y el tope de goma entra en contacto con el suelo, a la vez que se produce el enclavamiento del muelle de torsión por acción simultánea de la placa en uve, que impide el retroceso de la palanca y, por tanto, la desactivación del freno, hasta que el operario levanta 30 In this way, the brake is activated when the operator steps on the pedalboard, the lever descends and the rubber stop comes into contact with the ground, at the same time as the interlocking of the torsion spring by simultaneous action of the plate in uve, which prevents the reverse of the lever and, therefore, the deactivation of the brake, until the operator lifts

35 con el pie la pedalera para desenclavar el muelle de torsión, y retornar el dispositivo a su posición de descanso. 35 with the foot the pedalboard to unlock the torsion spring, and return the device to its resting position.

La base del vástago vertical de apoyo en el suelo está realizada en goma para proporcionar una mayor adherencia sobre la superficie de frenado, y el vástago cuenta con un muelle de amortiguación que permite compensar las variaciones que puedan existir en la superficie, tales como baches, resaltes, etc. The base of the vertical ground support rod is made of rubber to provide greater grip on the braking surface, and the rod has a damping spring that compensates for variations that may exist on the surface, such as potholes, highlights, etc.

En una variante de diseño, el freno puede estar constituido por dos dispositivos fijados en el mismo eje transversal de la plataforma inferior del carro, unidos mediante una misma palanca con pedalera en el centro de ambos, por prolongación de los dos vástagos transversales roscados de la palanca, pasante el superior por los vértices de los catetos In a design variant, the brake can be constituted by two devices fixed on the same transverse axis of the lower platform of the carriage, connected by a same lever with pedalboard in the center of both, by prolonging the two threaded transverse rods of the lever, through the upper one through the vertices of the legs

Este sistema de frenado presenta la ventaja de que es compacto y de tamaño reducido, lo que permite que se pueda adaptar a diferentes alturas de carro. Es un dispositivo útil, en This braking system has the advantage that it is compact and small in size, allowing it to adapt to different carriage heights. It is a useful device, in
