Description

Mecanismo para la apertura y cierre controlado de puertas para automóviles.Mechanism for controlled opening and closing of car doors.

Más concretamente, la invención se refiere a un mecanismo integrado en el eje de giro de la puerta de un automóvil, de manera que obliga a dicha a puerta a girar para abrirse y cerrarse de manera escalonada, y siempre en contra de una fuerza intermitente, suministrada por dicho mecanismo sobre el citado eje de la puerta.More specifically, the invention relates to a mechanism integrated in the axis of rotation of the door of a car, so that forces said door to turn to open and close staggered, and always against a force intermittent, supplied by said mechanism on said axis of the door.

La finalidad del mecanismo es evitar que en condiciones de funcionamiento desfavorable de la puerta del automóvil, la puerta se abata sobre el usuario y le golpee inopinadamente, o bien lo aprisione entre la puerta y el marco de la puerta, o bien la puerta golpee una pared, columna, o la puerta de otro automóvil cuando está aparcado en las proximidades de otro.The purpose of the mechanism is to prevent unfavorable operating conditions of the door car, the door locks on the user and hits him unexpectedly, or else imprison him between the door and the frame of the door, or the door knocks on a wall, column, or the door of another car when parked in the vicinity of other.

En el sector del automóvil la disposición habitual en estos casos, es montar la puerta a la carrocería por tres puntos de equilibrio mediante el auxilio de las correspondientes bisagras, existiendo un tirante de seguridad que evita que la puerta pueda girar más de un ángulo determinado, cuando la misma se abre, dicho tirante tiene uno de sus extremos montado en la puerta y el otro montado en la carrocería.In the automotive sector the provision usual in these cases, is to mount the door to the body by three balance points by the help of corresponding hinges, there is a safety strap that prevents the door from rotating more than a certain angle, when it opens, said brace has one of its ends mounted on the door and the other mounted on the body.

Esta disposición que denominaremos como convencional permite a la puerta girar libremente con solo empujarla, o bien atraerla hacia la carrocería, con lo cual la única fuerza que hay que vencer al abrir o cerrar es la del propio peso de la puerta y el rozamiento propio de las bisagras, con lo cual con un golpe de viento, o bien cuando la puerta se abre estando el coche inclinado, es posible que la puerta a la que se deja de empujar hacia fuera se abata rápidamente sobre el usuario golpeándolo y ocasionándole daños corporales, principalmente en las extremidades
inferiores.This provision that we will call as conventional allows the door to rotate freely by simply pushing it, or attracting it towards the body, with which the only force that must be overcome when opening or closing is that of the door's own weight and the friction of the hinges, with which with a blow of wind, or when the door is opened while the car is tilted, it is possible that the door to which it stops pushing out quickly collapses on the user hitting it and causing bodily harm, mainly in the extremities
lower.

En otros casos cuando la inclinación del coche es inversa a la descrita en el párrafo anterior, la puerta que gira impelida hacia fuera por el empuje transmitido por el usuario se le suma la acción de la gravedad, si bien no daña al usuario si que puede dañar objetos próximos al coche además de la cara exterior de la propia puerta.In other cases when the inclination of the car It is the opposite of the one described in the previous paragraph, the door that turns impelled out by the push transmitted by the user will be adds the action of gravity, although it does not harm the user if can damage objects near the car in addition to the outer face from the door itself.

El mecanismo objeto de la presente invención suministra en el propio eje de giro de la misma una fuerza de retención de carácter intermitente, tanto cuando se abre como cuando se cierra, de manera que el giro al contrario de lo que sucede en el estado de la técnica no es libre y la puerta se queda siempre en la posición que la deja el usuario, tanto cuando la abre como cuando la cierra, evitando que la puerta gire libremente con los efectos no deseados para el usuario y para la propia puerta, anteriormente descritos.The mechanism object of the present invention supplies a force of at the same axis of rotation intermittent retention, both when opened and when it closes, so that the opposite turn of what happens in the state of the art is not free and the door stays always in the position left by the user, both when opened like when you close it, preventing the door from turning freely with unwanted effects for the user and for the door itself, previously described.

Dicho mecanismo está formado por unos medios de presión sobre el eje de giro de la puerta, que actúan como medios de retención del giro del eje del mecanismo que es el eje de la puerta, dichos medios de presión perpendiculares al eje de la puerta, están formados por una palanca que gira alrededor del eje exterior al eje de giro de la puerta previsto en las proximidades de un extremo de dicha palanca, mientras que en el extremo opuesto finaliza en una superficie convexa que está en contacto con un empujador.Said mechanism is formed by means of pressure on the axis of rotation of the door, acting as means of retention of the rotation of the axis of the mechanism that is the axis of the door, said pressure means perpendicular to the axis of the door, are formed by a lever that rotates around the axis outside the axis of rotation of the door provided in the vicinity of one end of said lever, while at the opposite end ends on a convex surface that is in contact with a pusher

En el interior de esta palanca se ha previsto una cavidad preferentemente cilíndrica que incorpora en su interior una funda con un muelle, cuya acción expansiva empuja la funda cuya base presenta una protuberancia que encaja o no con la superficie cóncava de la base superior del empujador.Inside this lever is planned a preferably cylindrical cavity that incorporates in its inside a cover with a spring, whose expansive action pushes the cover whose base presents a protuberance that fits or not with the concave surface of the upper base of the pusher.

Los medios de retención comprenden dos ruedas dentadas cilíndricas, (una para cada movimiento de la puerta: apertura-cerramiento), cuya superficie lateral incluye un dentado, que trabaja en combinación con dos mordazas, cuyas protuberancias (una por mordaza) siguen el dentado de las ruedas dentadas, cuando la puerta se abre o bien cuando la puerta se cierra. Los dientes del casquillo quedan aprisionados por las dos protuberancias de las mordazas alineados en posición diametral.The retention means comprise two wheels cylindrical toothed, (one for each movement of the door: opening-closing), whose lateral surface includes a serrated, which works in combination with two jaws, whose protuberances (one per jaw) follow the teeth of the gear wheels, when the door opens or when the door closes. The teeth of the bush are imprisoned by the two protrusions of the jaws aligned in position diametral.

Cuando la puerta gira y también su eje que es el de la rueda dentada, los medios de presión ejercen una fuerza dirigida hacia dicho eje y perpendicular al mismo, de forma que la protuberancia presente en la base de la funda, sale de la cavidad prevista en la base superior cóncava del empujador, de manera que se libera la rueda dentada por uno de sus puntos de inmovilización, de forma que actúa sobre un simple mecanismo de "trinquete", es decir la base lateral de la palanca empuja los salientes previstos en la parte interior presente en unos de los extremos de la mordaza, y los dientes previstos en la parte interior de las mordazas resbalan sobre el dentado proyectado en la superficie lateral del casquillo.When the door rotates and also its axis which is the of the cogwheel, the pressure means exert a force directed towards said axis and perpendicular to it, so that the protuberance present at the base of the sheath, leaves the cavity provided on the upper concave base of the pusher, so that the cogwheel is released by one of its points of immobilization, so that it acts on a simple mechanism of "ratchet", that is to say the lateral base of the lever pushes the projections provided in the inner part present in one of the jaw ends, and the teeth provided in the part inside the jaws slide on the projected teeth in the lateral surface of the bushing.

Cuando la puerta gira en una dirección, se impide el giro del casquillo en el sentido opuesto, para ello las mordazas giran levemente hacia afuera merced a un bulón previsto en una de las extremidades de las mismas, por el empuje recibido de la propia puerta por intermedio de una palanca que gira respecto de un eje exterior y cuyo extremo trabaja en colaboración con un empujador en contacto por sus bases laterales con la parte interior de las mordazas, es decir, es necesario un pequeño movimiento en sentido opuesto al que se está llevando a cabo, por tal de bloquear el mecanismo y que la puerta quede en aquella posición.When the door turns in one direction, it prevents the rotation of the bushing in the opposite direction, for this the jaws turn slightly outwards thanks to a bolt provided in one of the extremities thereof, for the thrust received from the own door through a lever that rotates with respect to an outer axis and whose end works in collaboration with a pusher in contact by its lateral bases with the inner part of the jaws, that is, a small movement in opposite direction to the one being carried out, by such block the mechanism and the door is in that position.
