MECANISMO ANTICAÍDA DE BLOQUEO AUTOMÁTICO DE PUERTAS VERTICALESANTI-CHECK MECHANISM FOR AUTOMATIC LOCK DOORS

La presente invención se refiere a un mecanismo automático de bloqueo de puertas verticales, para evitar la caída de estas por la pérdida de tensión o rotura del elemento de suspensión de dicha puerta, permitiendo el movimiento ascendente de la misma pero no el descendente.The present invention relates to an automatic vertical door locking mechanism, to prevent their fall due to the loss of tension or breakage of the suspension element of said door, allowing the upward movement thereof but not the downward movement.

Antecedentes de la invenciónBackground of the invention

Son conocidos y, por tanto, forman parte del estado de la técnica, sistemas de freno automáticos que evitan la caída libre de puertas verticales ante la rotura de los medios de sustentación de la misma, donde dichos sistemas de freno conocidos discurren por el interior de la guía de desplazamiento de la puerta, y en caso de perder la tensión de los medios de sustentación de la puerta, despliegan unos frenos laterales que se encuentran retraídos en el normal funcionamiento de la puerta, gracias a la acción de tensión sobre el mecanismo que se desplaza con la puerta por la guía.They are known and, therefore, are part of the state of the art, automatic brake systems that prevent the free fall of vertical doors before the breaking of the support means thereof, where said known brake systems run through the interior of the door movement guide, and in case of losing the tension of the support means of the door, they deploy lateral brakes that are retracted in the normal operation of the door, thanks to the tension action on the mechanism that travels with the door through the guide.

La utilización de dichos sistemas de freno implica la instalación de un dispositivo de frenado en cada guía, teniendo que ser capaces de soportar el peso de la puerta en su frenado sobre la guía.The use of said brake systems implies the installation of a braking device in each guide, having to be able to support the weight of the door when braking on the guide.

Para evitar tener que instalar estos sistemas anteriores de freno, costosos y de eficacia sometida a dicha acción de freno, existen en el estado de la técnica sistemas de bloqueo automáticos en puertas seccionales que actúan sobre el eje de giro de la puerta vertical, realizando un bloqueo del eje de giro por trinquete ante la rotura del muelle. Los mecanismos conocidos que realizan este bloqueo automático, actúan sobre un trinquete solidario al eje de giro de la puerta vertical, mediante un mecanismo compuesto de diversos elementos intermedios, por un lado los elementos de paso de los medios de sustentación de la puerta o de detección de la perdida de dicha tensión y por otro lado los elementos de actuación sobre el gatillo que bloquea al trinquete, ante la pérdida de tensión de los medios de sustentación de la puerta, actúan uno detrás de otro, teniendo por ello una mayor probabilidad de fallo de los sistemas, al depender de diversos elementos intermedios para la actuación del gatillo, teniendo el coste de producción del mecanismo relativo a dichaTo avoid having to install these previous brake systems, expensive and efficient subject to said brake action, there are in the state of the art automatic locking systems in sectional doors acting on the axis of rotation of the vertical door, performing a ratchet shaft lock due to spring breakage. The known mechanisms that perform this automatic locking act on a ratchet integral with the axis of rotation of the vertical door, by means of a mechanism composed of several intermediate elements, on the one hand the passage elements of the means for supporting the door or detecting of the loss of said tension and on the other hand the elements of action on the trigger that blocks the ratchet, before the loss of tension of the means of support of the door, act one behind the other, thus having a greater probability of failure of the systems, depending on various intermediate elements for trigger action, having the production cost of the mechanism related to said

Descripción de la invenciónDescription of the invention

Con el mecanismo anticaída de bloqueo automático de puertas verticales, descritos en la presente invención, se consiguen resolver los inconvenientes citados, presentando otras ventajas que se describirán.With the anti-fall mechanism for automatic locking of vertical doors, described in the present invention, the aforementioned drawbacks are resolved, presenting other advantages that will be described.

La presente invención se basa en un mecanismo instalado en puertas verticales, preferentemente del tipo rápidas, aunque puede instalarse en otras puertas que dispongan de unos medios de sustentación de la puerta que utilicen correas, cintas, cadenas o elementos similares que están en tensión ya sea, o traccionando dicho eje de la puerta, o directamente traccionando sobre la puerta, o sustentando elementos de contrapeso de la misma de forma coordinada con el movimiento del eje de la puerta, o unidos a un muelle de efecto contrapeso, siendo dichos medios de sustentación, en dichas opciones, solidarios al giro del eje que desplaza la puerta verticalmente, referido en la presente descripción como eje de la puerta. Es decir, que dichos medios de sustentación actúan directamente sobre el aguante en una posición concreta de un elemento del sistema, ya sea, eje traccionado, puerta, muelle o contrapeso y que, ante la rotura del mismo, la puerta puede caer libremente.The present invention is based on a mechanism installed in vertical doors, preferably of the fast type, although it can be installed in other doors that have means of supporting the door using belts, belts, chains or similar elements that are in tension either , or by pulling said door axis, or directly by driving on the door, or by supporting counterweight elements thereof in a coordinated manner with the movement of the door axis, or attached to a counterweight spring, said support means being , in said options, integral to the rotation of the axis that moves the door vertically, referred to in the present description as the axis of the door. That is to say, said support means act directly on the endurance in a specific position of an element of the system, whether it is a driven shaft, a door, a spring or a counterweight and that, in the event of a breakage thereof, the door can fall freely.

Ya sea mediante el propio eje de la puerta, o mediante un elemento que se acople solidariamente a él, dicho eje de la puerta dispone de un elemento de anclaje para un trinquete, es decir que preferentemente dispone de un elemento con cavidades o protuberancias, o encajes de forma general, que permiten el bloqueo del eje de la puerta por la retención, en dichas aberturas o protuberancias, que realiza un gatillo o similar efectuando la acción del tipo trinquete.Either by means of the axis of the door itself, or by means of an element that fits in solidarity with it, said axis of the door has an anchoring element for a ratchet, that is to say that it preferably has an element with cavities or protuberances, or general fittings, which allow the blocking of the door axis by retention, in said openings or protuberances, which a trigger or the like performs by performing the action of the ratchet type.

Preferentemente, en las proximidades del elemento de anclaje, fijado a la estructura de la puerta o cualquier otro punto que permita hacerlo de forma independiente al movimiento giratorio de dicho elemento de anclaje, se tiene el sistema de trinquete, el cual dispone de un gatillo o elemento similar de bloqueo del elemento de anclaje, donde la pieza que contiene dicho gatillo se puede desplazar entre una posición de contacto y bloqueo en las cavidades o protuberancias, o encajes en general, del elemento de anclaje y una posición de separación de no contacto con dichas aberturas o protuberancias.Preferably, in the vicinity of the anchoring element, fixed to the structure of the door or any other point that allows it to be done independently of the rotating movement of said anchoring element, there is a ratchet system, which has a trigger or similar locking element of the anchoring element, where the part containing said trigger can be moved between a contact and locking position in the cavities or protuberances, or fittings in general, of the anchoring element and a non-contact separation position with said openings or protuberances.

De manera ventajosa para la invención, es la misma pieza que contiene el gatillo la que dispone de un elemento de contención del desplazamiento de dicha pieza, y por tanto del gatillo, en donde el elemento de contención se pone en contacto directamente con los medios de suspensión de la puerta, sin otros elementos auxiliares de actuación o transmisión de movimiento entre los medios de sustentación y la pieza del gatillo, quedando una única pieza que engloba el gatillo de bloqueo, y el elemento de contención.Advantageously for the invention, it is the same piece that contains the trigger which has a containment element for the movement of said piece, and therefore the trigger, where the containment element is directly in contact with the means of door suspension, without other auxiliary elements of actuation or transmission of movement between the support means and the trigger piece, leaving a single piece that encompasses the blocking trigger, and the containment element.

Este contacto entre los medios de sustentación, los cuales pueden estar preferentemente formados por la correa, cinta, cadena o similar y el elemento de contención, se realiza haciendo pasar dichos medios de sustentación en tensión por un punto en el que entran en contacto con el elemento de contención, impidiendo con la tensión de funcionamiento de los medios de sustentación el avance automático de la pieza de gatillo en la dirección y sentido de la posición de contacto y bloqueo, ya que la pieza del gatillo sufre la acción de un elemento impulsor que empuja siempre en dicha dirección y sentido de boqueo. En la presente invención se entiende como dirección y sentido de bloqueo el camino que ha de seguir la pieza del gatillo desde una posición separada de no-bloqueo, a la posición de bloqueo, ya sea un desplazamiento rectilíneo, curvado o radial, o combinado de los anteriores.This contact between the support means, which may preferably be formed by the belt, belt, chain or the like and the containment element, is made by passing said tension support means through a point where they come into contact with the containment element, preventing the automatic advance of the trigger piece in the direction and direction of the contact and lock position with the operating voltage of the lift means, since the trigger piece undergoes the action of a driving element that always push in that direction and direction of boque. In the present invention, the direction and direction of blocking is understood as the path to be taken by the trigger part from a separate non-blocking position, to the blocking position, whether a rectilinear, curved or radial, or combined movement of the above

El elemento impulsor, formado habitualmente por medios elásticos del tipo muelle o elementos que crean una fuerza en un sentido, como por ejemplo un contrapeso, se encuentra fijado a la pieza del gatillo desplazable de manera que en el momento que pierden tensión dichos medios de sustentación y, por tanto, deja de existir la fuerza contraria al desplazamiento de bloqueo que ejerce el elemento impulsor, la pieza del mecanismo anticaída que contiene al gatillo realiza un movimiento en la dirección y sentido de bloqueo anclándose dicho gatillo en el elemento de anclaje, bloqueando el giro del eje solidario a la puerta e impidiendo la caída libre de la misma, como causa de dicha perdida de tensión que habrá sido producida a su vez por la rotura de la cadena, cinta, correa o similar. Una vez activado el bloqueo automático, el dispositivo permite el giro del eje que desplaza la puerta en el sentido ascendente, para poder abrir la misma.The driving element, usually formed by spring-like elastic means or elements that create a one-way force, such as a counterweight, is fixed to the movable trigger part so that at the moment said lift means lose tension and, therefore, the force contrary to the blocking displacement exerted by the driving element ceases to exist, the piece of the fall arrest mechanism that contains the trigger makes a movement in the direction and direction of blockage by anchoring said trigger in the anchoring element, blocking the rotation of the shaft integral to the door and preventing the free fall of the same, as a cause of said loss of tension that will have been produced in turn by the breakage of the chain, tape, belt or the like. Once the automatic locking is activated, the device allows the rotation of the axis that moves the door in the upward direction, in order to open it.

El desplazamiento de la pieza de gatillo se puede realizar, de manera preferente, ya sea siguiendo unos medios de guiado o realizando un movimiento articulado por un punto, siempre teniendo un desplazamiento automático en un sentido y en dirección al bloqueo delThe displacement of the trigger piece can be carried out, preferably, either following a guide means or performing a movement articulated by a point, always having an automatic movement in one direction and in the direction of blocking the

De este modo el mecanismo anticaída de bloqueo automático de puertas verticales, consigue de manera ventajosa, mediante una configuración simple, con lo que más barata de construcción y de funcionamiento, realizar el bloqueo automático de la puerta en la que se instala, utilizándose una única pieza que engloba el gatillo de bloqueo, y el elemento de contención para evitar, en el funcionamiento normal, dicho bloqueo, y solamente bajo la perdida de tensión de las cintas, cuerdas, correas, cadenas o similares, se realiza dicho desplazamiento automático de la pieza del gatillo hacia la posición de bloqueo.In this way, the automatic locking mechanism for automatic locking of vertical doors, advantageously, by means of a simple configuration, makes it cheaper to build and operate, to automatically lock the door on which it is installed, using a single piece that includes the blocking trigger, and the containment element to avoid, in normal operation, said blocking, and only under the loss of tension of the tapes, ropes, belts, chains or the like, is said automatic displacement of the trigger part towards the locked position.

Descripción de una realización preferidaDescription of a preferred embodiment

En la presente realización preferida de la invención, se tiene que el mecanismo (10) anticaída de bloqueo automático de puertas verticales, tal y como puede verse en las figuras de la 1 a la 3, se monta en una puerta rápida (11) que se enrolla en un eje (12), el cual se encuentra motorizado y dispone de un contrapeso (13) para ayudar a la elevación de la puerta rápida (11). Como es conocido en puertas que usan un elemento, como el contrapeso (13), que ejerce una fuerza de ayuda a la ascensión de dicha puerta, dicho contrapeso (13) se puede sustituir por un muelle o elemento elástico similar.In the present preferred embodiment of the invention, it is necessary that the automatic locking mechanism (10) for automatic locking of vertical doors, as can be seen in figures 1 to 3, be mounted on a rapid door (11) which It is wound on a shaft (12), which is motorized and has a counterweight (13) to help lift the rapid door (11). As is known in doors that use an element, such as the counterweight (13), which exerts a force to aid the ascension of said door, said counterweight (13) can be replaced by a spring or similar elastic element.

La puerta rápida (11), como se ha dicho, dispone de un contrapeso (13), y unido solidariamente a él (13) se tienen los medios de sustentación de dicho contrapeso (13), donde dichos medios de sustentación están formados por una correa (14) de sustentación que por un extremo se une solidariamente al contrapeso (13) y por el otro extremos se une solidariamente al giro del eje (12) donde se enrolla y desenrolla la puerta (11) para que pueda realizar el efecto propio de contrapeso.The rapid door (11), as has been said, has a counterweight (13), and joined in solidarity with it (13) there are the means of support of said counterweight (13), where said means of support are formed by a support belt (14) that at one end joins the counterweight (13) in solidarity and at the other end joins the shaft (12) in rotation where the door (11) is wound and unwound so that it can perform its own effect Counterweight

Esta correa (14) de sustentación se encuentra en tensión, para poder transmitir a través de ella el movimiento del giro del eje (12), así como la fuerza de la gravedad del contrapeso (13) a dicho eje (12). Una rotura de dicha correa (14) de sustentación implicaría una pérdida de tensión inmediata, así como la falta de empuje por gravedad del contrapeso (13), con lo que el motor que sostiene el eje (12) de la puerta (11), contra su caída y que realiza su levantamiento vertical, no podría realizar el aguante de dicha puerta (11) con lo que caería.This support belt (14) is in tension, in order to be able to transmit through it the movement of the rotation of the axis (12), as well as the force of the gravity of the counterweight (13) to said axis (12). A rupture of said support belt (14) would imply an immediate loss of tension, as well as the lack of thrust due to gravity of the counterweight (13), whereby the motor that supports the axis (12) of the door (11), against its fall and carrying out its vertical lifting, it could not hold the endurance of said door (11) with what would fall.

Para evitar esto, solidario al eje (12) de giro de la puerta (11) se encuentra un elemento de anclaje (15) formado por un disco fijado en el eje que dispone de encajes (16) para el anclaje de una pieza de forma complementaria a dicho rebaje en el disco, que forma el encaje (16). El mecanismo (10) anticaída de bloqueo automático se forma, en la presente realización por una pieza (20) que puede realizar un desplazamiento radial al tener un punto de articulación/giro (24) fijo, donde dicha pieza (20) engloba en ella misma tres elementos, un gatillo (21) que encaja en la forma correspondiente de los medios de anclaje (15), un elemento de contención (22) que entra en contacto con la correa (14) de sustentación enTo avoid this, attached to the axis (12) of rotation of the door (11) is an anchoring element (15) formed by a disk fixed on the shaft that has fittings (16) for the anchoring of a shape piece complementary to said recess in the disc, which forms the socket (16). The automatic locking mechanism (10) in the present embodiment is formed by a piece (20) that can perform a radial displacement by having a fixed point of articulation / rotation (24), where said part (20) encompasses it same three elements, a trigger (21) that fits in the corresponding form of the anchoring means (15), a containment element (22) that comes into contact with the support belt (14) in

tensión y un elemento de conexión a un elemento impulsor (23) que ejerce una fuerza sobre la pieza (20) para que ésta (20) realice su desplazamiento. El elemento impulsor (23) no tiene porqué formar parte estrictamente de la misma pieza (20), ya que como se puede ver, dicha pieza (20) lo que dispone es un elemento conectado a dicho elemento impulsor (23), bastando con una abertura, o de forma general, un elemento de anclaje para su acción sobre la pieza (20).tension and a connecting element to a driving element (23) that exerts a force on the part (20) so that it (20) makes its displacement. The driving element (23) does not have to be strictly part of the same part (20), since as it can be seen, said part (20) what it has is an element connected to said driving element (23), just a opening, or generally, an anchoring element for its action on the piece (20).

Como se ha dicho, la pieza (20) que incorpora el gatillo (21) se puede desplazar radialmente pivotando en el punto de articulación/giro (24) fijo. El gatillo (21) se encuentra en uno de los extremos de la pieza (20) desplazándose radialmente entre una posición en la que no entraría en contacto con el movimiento de los medios de anclaje (15), hasta una posición en la que dicho gatillo (21) entraría en contacto con los encajes (16) de dichos medios de anclaje (15) bloqueando el movimiento del disco y, por tanto, impidiendo el movimiento del eje (12) de giro de la puerta (11) y por tanto evitando el desplazamiento del eje (12) en el sentido de giro de bajada de la puerta y por tanto su caída, manteniendo la posibilidad de giro del eje (12) en el sentido de subida de la puerta.As mentioned, the part (20) incorporating the trigger (21) can be moved radially by pivoting at the fixed point of articulation / rotation (24). The trigger (21) is located at one of the ends of the part (20) moving radially between a position where it would not come into contact with the movement of the anchoring means (15), to a position in which said trigger (21) would come into contact with the fittings (16) of said anchoring means (15) blocking the movement of the disk and, therefore, preventing the movement of the axis (12) of rotation of the door (11) and therefore avoiding the displacement of the axis (12) in the direction of rotation of the door down and therefore its fall, maintaining the possibility of rotation of the axis (12) in the direction of the door's rise.

Para que se produzca de manera automática este bloqueo del giro del eje (12) de la puerta (11), el elemento impulsor (23) ejerce una fuerza en el sentido desplazamiento del gatillo (21) hacia la posición de bloqueo de los elementos de anclaje (15), y es el elemento de contención (22), formado por una superficie de contacto, en la presente realización un estribo de la misma pieza (20) del gatillo (21), que al entrar en contacto con la correa (14) de sustentación en tensión, dicha correa (14) en tensión impide que la pieza (20) avance hacia la posición de bloqueo hacia donde la impulsa un muelle, como elemento impulsor (23). Dicho contacto se produce porqué el recorrido de la correa (14) de sustentación se hace pasar cortando el camino de desplazamiento que ha de seguir la pieza (20) del gatillo (21).In order to automatically produce this blockage of the rotation of the axis (12) of the door (11), the impeller element (23) exerts a force in the direction of movement of the trigger (21) towards the blocking position of the elements of anchor (15), and is the containment element (22), formed by a contact surface, in the present embodiment a stirrup of the same piece (20) of the trigger (21), which when coming into contact with the belt ( 14) of tension support, said tension belt (14) prevents the piece (20) from moving towards the locked position towards which a spring drives it, as the driving element (23). Said contact occurs because the travel of the support belt (14) is passed by cutting the path of travel that the trigger part (20) has to follow (21).

De forma alternativa, el elemento de impulsor (23) puede ser un peso que gracias a la fuerza de gravedad impulse a la pieza (20) del gatillo (21) en el sentido de bloqueo.Alternatively, the impeller element (23) can be a weight which, thanks to the force of gravity, drives the trigger part (20) (21) in the blocking direction.

Por otro lado, y también de manera alternativa, tal y como se muestra en las figuras 4 y 5, el desplazamiento de la pieza (20) del gatillo (21) se puede hacer a través de unos medios de guiado (25) que describan la trayectoria a seguir por la pieza (20) del gatillo (21) entre las dos posiciones, la separada de los medios de anclaje (15) y la de bloqueo, donde la correa (14) de sustentación del contrapeso (13) se hace pasar cortando el camino deOn the other hand, and also alternatively, as shown in Figures 4 and 5, the displacement of the trigger piece (20) (21) can be done through guiding means (25) that describe the path to be followed by the trigger piece (20) (21) between the two positions, the one separated from the anchoring means (15) and the locking means, where the counterbalance support belt (14) (13) is made pass by cutting the path of

desplazamiento del elemento de contención (22) de la pieza (20) y el elemento impulsor (23) impulsa del mismo modo en el sentido de bloqueo, ya sea mediante muelle o peso.displacement of the containment element (22) of the part (20) and the impeller element (23) drives in the same way in the blocking direction, either by spring or weight.

Como se ha indicado en la descripción, los medios de sustentación que se cruzan en la 5 trayectoria de desplazamiento de la pieza del gatillo pueden ser de diferente origen y función, tanto estando formados por correas, cintas, cadenas, cuerdas o similares, así como elemento de sujeción del contrapeso o muelle/contrapeso, tal y como se ha indicado en la realización anterior, así como alternativamente formando parte de la transmisión de la tracción del motor al eje de giro, o de la sujeción/tracción directa de la puerta estando 10 solidarizados a dicha puerta en su parte inferior/media y realizando la tracción directamente de la puerta los medios de sustentación. Todos estos posibles medios de sujeción necesitan que el elemento sustentador del tipo correa, cuerda, cinta, cadena o similar, se solidarice al eje de giro que arrastrará la puerta y se mantenga en tensión durante el funcionamiento normal de la puerta vertical y una rotura o perdida de tensión pueda desembocar en la caída 15 de la puerta.As indicated in the description, the support means that intersect in the movement path of the trigger piece can be of different origin and function, both being formed by belts, ribbons, chains, ropes or the like, as well as fastening element of the counterweight or spring / counterweight, as indicated in the previous embodiment, as well as alternatively forming part of the transmission of the traction of the motor to the axis of rotation, or of the direct attachment / traction of the door being 10 in solidarity with said door in its lower / middle part and carrying out the support directly from the door. All these possible fastening means require that the support element of the type belt, rope, tape, chain or the like, be in solidarity with the axis of rotation that will drag the door and be held in tension during normal operation of the vertical door and a break or Loss of tension can lead to the fall 15 of the door.

A pesar de que se ha hecho referencia a una realización concreta de la invención, es evidente para un experto en la materia que el mecanismo anticaída de bloqueo automático de puertas verticales descrito es susceptible de numerosas variaciones y modificaciones, y 20 que todos los detalles mencionados pueden ser substituidos por otros técnicamente equivalentes, sin apartarse del ámbito de protección definido por las reivindicaciones adjuntas.Although reference has been made to a specific embodiment of the invention, it is apparent to one skilled in the art that the described automatic vertical door locking anti-fall mechanism is susceptible to numerous variations and modifications, and that all the mentioned details they can be replaced by technically equivalent ones, without departing from the scope of protection defined by the appended claims.
