Background of the invention

En el ámbito de aplicación práctica de la invención, son conocidos múltiples soluciones en los enganches de bola para remolques, presentando todos ellos como denominador común el hecho de que suponen un peligro cuando el vehículo remolcado, por la causa de que se trate vuelca, de manera que los medios de enganche, si bien permiten una cierta basculación entre los mismos, dicha basculación está seriamente limitada, sobretodo en lo que se refiere al plano vertical, de manera que, como se decía, el movimiento de vuelco se transmite, ligeramente desfasado al vehículo tractor, pudiendo provocar igualmente su volcado, con el consecuente riesgo para la vida del operario.In the practical scope of the invention, multiple solutions are known in the hooks of ball for trailers, presenting all of them as common denominator the fact that they pose a danger when the towed vehicle, by the cause in question overturns, so that the means of hitch, although they allow some tilt between them, such tilting is seriously limited, especially as regards refers to the vertical plane, so that, as they said, the rollover movement is transmitted, slightly out of date to the vehicle tractor, and can also cause its dump, with the consequent risk to the life of the operator.

Description of the invention

El dispositivo que se preconiza ha sido concebido para resolver la problemática anteriormente expuesta, merced a una solución sencilla, pero de gran eficacia.The device that has been recommended has been designed to solve the problem described above, thanks to a simple solution, but of great efficiency.

Para ello, y de forma más concreta, el dispositivo de la invención está constituido a partir de un cuerpo de configuración diédrica, en el que se define una superficie horizontal, con un orificio en el que se recibe a la bola a la que se adapta el enganche del remolque o vehículo de que se trate, mientras que en el plano vertical del diedro se dispone un brazo basculante, arqueado, cuyo extremo libre queda enfrentado superiormente al centro de la bola de enganche, extremo en el que es ajustable verticalmente un tornillo, que en situación de montaje inmoviliza la bola.To do this, and more specifically, the device of the invention is constituted from a body of dihedral configuration, in which a surface is defined horizontal, with a hole in which you receive the ball to which the trailer hitch or vehicle in question is adapted, while in the vertical plane of the dihedral one arm is arranged tilting, arched, whose free end faces superior to the center of the hitch ball, end where it is vertically adjustable a screw, which in mounting situation immobilizes the ball

El citado brazo es bloqueable mediante el empleo de un pasador, que se dispone transversalmente al mismo, y paralelo al eje de basculación del brazo, ligeramente por debajo de éste, siendo pasante a través de dos paredes laterales y paralelas que emergen de la pared vertical, afectadas de orificios para paso del eje de giro y del pasador, y que definen el alojamiento y los medios de basculación para el brazo.The aforementioned arm is lockable by use of a pin, which is arranged transversely to it, and parallel to the arm tilt axis, slightly below it, being through two side and parallel walls that emerge from the vertical wall, affected by holes for passage of axis of rotation and pin, and defining the housing and the means of tilt for the arm.

El pasador, tendrá una resistencia a la cizalladura sensiblemente menor que el resto de componentes que participan en el dispositivo, de manera que, a partir de esta estructuración, cuando se produzca un vuelco accidental del remolque o elemento remolcado de que se trate, el propio elemento de enganche del remolque conjuntamente con la bola, ejercerán una presión sobre el tornillo asociado al extremo libre del brazo arqueado, y consecuentemente sobre éste, el cual se transmitirá por efecto palanca al pasador, a través del correspondiente eje de giro, presión que se ve multiplicada por dicho efecto palanca sobre el citado pasador, el cual partirá a cizalladura, liberando el movimiento basculante del brazo, el cual, basculará ascendentemente, liberando al dispositivo de enganche del remolque, evitando así el vuelco del vehículo tractor.The pin will have a resistance to shear significantly less than the other components that participate in the device, so that, from this structuring, when an accidental tipping of the trailer occurs or towed element in question, the hitch element itself of the trailer together with the ball, will exert pressure on the screw associated with the free end of the arched arm, and consequently on this one, which will be transmitted by effect lever to the pin, through the corresponding axis of rotation, pressure that is multiplied by said lever effect on the said pin, which will split into shear, releasing the swing arm movement, which, will rock up, releasing the trailer hitch device, thus avoiding Tipping of the tractor vehicle.

Se consigue de esta manera, y mediante una estructuración sencilla, un dispositivo sumamente eficaz y rápido en su manejo, totalmente seguro frente a posibles vuelcos del elemento remolcado.It is achieved in this way, and through a simple structuring, an extremely efficient and fast device in its handling, totally safe against possible overturning of the element towed.

Preferred Embodiment of the Invention

A la vista de las figuras referidas, puede observarse como el dispositivo de la invención está constituido a partir de un bastidor (1), diédrico, en el que se define un plano horizontal (2) y un plano vertical (3), plano horizontal en cuya zona media anterior se establece un orificio (4) en el que juega el vástago (5) de la bola (6) en la que está destinada a acoplarse los medios de enganche del vehículo a remolcar, no representados en las figuras.In view of the referred figures, you can observe how the device of the invention is constituted to starting from a dihedral frame (1), in which a plane is defined horizontal (2) and a vertical plane (3), horizontal plane in whose middle anterior zone a hole (4) is established in which the rod (5) of the ball (6) in which it is intended to engage the means for hitching the vehicle to be towed, not represented in the figures.

Por su parte, en el plano vertical (3), se define un alojamiento (7) para un brazo arqueado (8), delimitado por dos paredes verticales (9), que emergen perpendicularmente de dicho plano vertical (3), en su zona media superior, paredes que están afectadas de dos orificios pasantes, un primer orificio pasante superior (10) receptor del eje de giro (11) para el brazo arqueado (8), el cual bascula a partir de su zona de acodamiento, brazo que por su extremidad superior se remata en un orificio roscado en el que es regulable en altura un tornillo (12), que queda enfrentado a la bola (6), impidiendo su desplazamiento cuando el brazo arqueado (8) está inmovilizado, para lo cual se ha previsto que con el mismo participe un pasador (13), el mostrado en detalle en la figura 6, destinado a introducirse a través de respectivos orificios inferiores (14) practicados en las paredes verticales (9), y que quedan enfrentados en situación de bloqueo con un orificio pasante (15) practicado en correspondencia con la extremidad inferior del brazo arqueado (8).On the other hand, in the vertical plane (3), defines a housing (7) for an arched arm (8), delimited by two vertical walls (9), which emerge perpendicularly from said vertical plane (3), in its upper middle area, walls that are affected from two through holes, a first through hole upper (10) pivot shaft receiver (11) for the arched arm (8), which swings from its cornering area, which arm by its upper extremity it is finished off in a threaded hole in the which is a height adjustable screw (12), which faces the ball (6), preventing its displacement when the arched arm (8) is immobilized, for which it is expected that with the same a pin (13) participates, the one shown in detail in figure 6, intended to be introduced through respective holes lower (14) practiced on the vertical walls (9), and that they face each other in a blocking situation with a through hole (15) practiced in correspondence with the lower extremity of the arched arm (8).

Así pues, y tal y como se puede observar en la figura 5, cuando el pasador (13) rompe por cizalladura, el brazo arqueado (8) queda liberado, permitiendo extraer el conjunto bola-enganche de remolque, y evitando así que dicho elemento remolcado pueda provocar el vuelco del vehículo tractor.So, and as can be seen in the Figure 5, when the pin (13) breaks by shear, the arm arched (8) is released, allowing to extract the set tow ball-hitch, and avoiding so said towed item may cause the vehicle to tip over tractor.
