Description

"CERRADURA CORTAFUEGOS CON BLOQUEO DE PICAPORTE"  "FIRE CLOSURE LOCK WITH PICAPORTE LOCK"
CAMPO DE LA INVENCIÓN  FIELD OF THE INVENTION
Esta invención concierne a una cerradura cortafuegos con bloqueo de picaporte de las que disponen de una caja de cerradura con un eje central de simetría y aberturas de inserción equidistantes para cilindros de cerradura arriba y abajo del eje central para su uso indistinto en puertas con apertura a derechas o izquierdas, y un picaporte que sobresale a la altura de un eje central a partir del frente de cerradura.  This invention concerns a fire lock with latch lock, which has a lock box with a central axis of symmetry and equidistant insertion openings for lock cylinders above and below the central axis for indistinct use in doors with opening to right or left, and a handle that protrudes at the height of a central axis from the front of the lock.
ESTADO DE LA TÉCNICA ANTERIOR  STATE OF THE PREVIOUS TECHNIQUE
En la actualidad y como referencia al estado de la técnica, es habitual y conocido en las cerraduras cortafuegos el uso de un picaporte centrado, con dos nuecas y bombillos distribuidos simétricamente respecto al eje central de la cerradura. Además del picaporte, existen modelos que incorporan una palanca accionada mediante la leva existente en el cilindro de cerradura. Estos modelos de cerradura cortafuegos presentes en el mercado, suelen usar dos tipos de soluciones que presentan los siguientes inconvenientes. En primer lugar, en las cerraduras cortafuegos actuales es habitual el bloqueo del giro de la nueca que activa la retracción del picaporte. Este bloqueo de la nueca puedo provocar que se produzcan daños en los mecanismos internos de la cerradura si se aplica un par excesivo sobre la manilla. El segundo de los inconvenientes que presentan las soluciones existentes para cerraduras cortafuegos e n la actualidad es que existe la posibilidad de retirar el picaporte actuando sobre la manilla o mediante manipulación para su apertura fraudulenta, aun teniendo la palanca proyectada. Esta acción de retraer el picaporte provoca que la puerta se descoloque respecto al marco donde se alojaba dicho picaporte, a pesar de tener la palanca proyectada, ya que estas palancas presentan holguras excesivamente grandes con respecto al marco y por lo tanto, las juntas intumescentes ya no realizan su función correctamente en caso de incendio. Por ejemplo la patente EP 2584124 muestra una cerradura reversible con una caja de cerradura y un pestillo que sobresale a la altura del eje central, incorporando aberturas para alojar el cilindro de cerradura a ambos lados del eje. Añadidamente, dispone de un cerrojo que puede desplazarse dos vuelta y quedar bloqueado mediante una guarda en las que engrana el paletón. At present and as a reference to the state of the art, it is usual and known in the fire locks the use of a centered latch, with two nuts and lightbulbs distributed symmetrically with respect to the central axis of the lock. In addition to the latch, there are models that incorporate a lever operated by the existing cam in the lock cylinder. These models of firewall lock present in the market, usually use two types of solutions that have the following drawbacks. In the first place, in the current fire locks, it is usual to block the rotation of the nut that activates the retraction of the latch. This nut lock can cause damage to the internal mechanisms of the lock if excessive torque is applied to the handle. The second of the disadvantages of existing solutions for fire locks at present is that there is the possibility of removing the handle acting on the handle or by manipulation for fraudulent opening, even having the lever projected. This action of retracting the latch causes the door to discolor with respect to the frame where said latch was housed, despite having the projected lever, since these levers have excessively large clearances with respect to the frame and therefore, the intumescent joints already They do not perform their function correctly in case of fire. For example, EP 2584124 shows a reversible lock with a lock box and a latch that protrudes at the height of the central axis, incorporating openings to accommodate the lock cylinder on both sides of the axis. Additionally, it has a bolt that can move two turns and be locked by a guard in which the pallet engages.
La patente EP 2484851 describe una cerradura de embutir para uso a derechas e izquierdas que comprende internamente en la carcasa de la cerradura al menos un pestillo trasladable, al menos un perno trasladable, una primera y seg u nda barra trasladables en direcciones transversalmente opuestas a la dirección de traslación del perno y el pestillo entre una posición de desbloqueo de la puerta, en la cual la primera y segunda barra están retraídas hacia el interior de la carcasa, y una posición de puerta bloqueada, en la cual se prolonga hacia el exterior de la carcasa.  EP 2484851 describes a mortise lock for right and left use internally comprising in the lock housing at least one transferable latch, at least one translatable bolt, a first and second transposable bar in transversely opposite directions to the direction of translation of the bolt and the latch between an unlocking position of the door, in which the first and second bars are retracted into the housing, and a locked door position, in which it extends outwards from the housing
EXPLICACIÓN DE LA INVENCIÓN Y VENTAJAS  EXPLANATION OF THE INVENTION AND ADVANTAGES
Frente a este estado de cosas la presente invención hace referencia a una cerradura cortafuegos con bloqueo de picaporte que incorpora una palanca vinculada al balancín y a la campanera susceptible de desplazarse horizontal y solidariamente al actuar sobre la leva del cilindro de cerradura en su posición de bloqueo, impidiendo el contacto del extremo de accionamiento de la nueca en su desplazamiento de giro con la pestaña accionadora del balancín.  In the face of this state of affairs, the present invention refers to a fire lock with a latch lock that incorporates a lever linked to the rocker arm and the bell that can move horizontally and jointly when acting on the cam of the lock cylinder in its locked position, preventing contact of the driving end of the nut in its rotation movement with the rocker actuator flange.
Cabe destacar que la palanca es capaz de desactivar el mecanismo de retracción de picaporte mediante interacción de nueca y balancín tanto si dispone de salientes de bloqueo como si carece de ellos.  It should be noted that the lever is able to deactivate the latch retraction mechanism by means of nut and rocker interaction whether it has locking projections or if it lacks them.
Gracias a esta configuración, al desplazar la palanca a la posición de bloqueo, la nueca gira en vacio, no pudiendo retirar el picaporte al no existir contacto entre el extremo de accionamiento de la nueca y la pestaña accionadora del balancín. De este modo, se evita que al aplicar un excesivo par en la manilla se pueda dañar alguna parte del mecanismo interno de la cerradura, o bien la retracción del picaporte y una consecuente descolocación del mismo en su alojamiento en el marco, provocando la consiguiente pérdida de presión sobre las juntas intumescentes que aseguran el aislamiento contra el fuego. Thanks to this configuration, when the lever is moved to the locked position, the nut rotates in a vacuum, and the latch cannot be removed as there is no contact between the nut's drive end and the rocker arm. In this way, it is avoided that by applying excessive torque on the handle, some part of the internal mechanism of the lock can be damaged, or the retraction of the latch and a consequent dislocation of the same in its housing in the frame, causing the consequent loss of pressure on the intumescent joints that ensure the insulation against fire.
Otra característica de la invención es que la palanca dispone de una cara bloqueante susceptible de vincularse con la zona activa de bloqueo del picaporte impidiendo la retracción de dicho picaporte cuando se encuentra en la posición de bloqueo.  Another feature of the invention is that the lever has a blocking face capable of being linked to the active locking area of the latch preventing the retraction of said latch when it is in the locked position.
Gracias a la configuración de la palanca, el picaporte no puede retraerse de su posición impidiendo de esta forma que pueda ser forzado violentamente por medio de una tarjeta o similar. Al actuar sobre el bombillo de cerradura, la leva desplaza horizontalmente el conjunto de campanera y palanca desde la posición de reposo, en la que el picaporte puede retraerse al actuar sobre la nueca, hasta la posición de bloqueo en la cual la cara bloqueante de la palanca entra en contacto con la zona activa del picaporte ejerciendo de tope e impidiendo que el mismo pueda retraerse.  Thanks to the configuration of the lever, the handle cannot be retracted from its position, preventing it from being violently forced by means of a card or similar. When acting on the lock bulb, the cam horizontally moves the bell and lever assembly from the rest position, in which the latch can be retracted when acting on the nut, to the locked position in which the blocking face of the Lever comes into contact with the active area of the latch acting as a stop and preventing it from retracting.
Es de señalar que la palanca admite diferentes ejecuciones, pudiendo incluir unos salientes de bloqueo que se proyectan en el marco de la puerta una vez que se ha activado la posición de bloqueo, o p udiendo carecer de ellos, siendo ambas configuraciones capaces de desactivar la interacción entre la nueca y el balancín y del bloquear el picaporte.  It should be noted that the lever supports different executions, and may include blocking projections that project into the door frame once the locking position has been activated, opting to lack them, both configurations being able to deactivate the interaction between the nut and the rocker arm and lock the latch.

EXPOSICION DE UNA REALIZACIÓN PREFERENTE  EXHIBITION OF A PREFERRED EMBODIMENT
Con relación a los dibujos y referencias arriba enumerados, se ilustra en los planos adjuntos un modo de ejecución preferente del objeto de la invención, referido a una cerradura cortafuegos con bloqueo de picaporte de las que incorpora una palanca (6) vinculada al balancín (7) y a la campanera (8) susceptible de desplazarse horizontal y solidariamente al actuar sobre la leva (13) del cilindro de cerradura (12) en su posición de bloqueo impidiendo el contacto del extremo de accionamiento (2a) de la nueca (2) en su desplazamiento de giro con la pestaña accionadora (7a) del balancín (7).  In relation to the drawings and references listed above, a preferred embodiment of the object of the invention is illustrated in the attached drawings, referring to a fire lock with latch lock of which incorporates a lever (6) linked to the rocker arm (7). ) and to the bell (8) capable of moving horizontally and jointly when acting on the cam (13) of the lock cylinder (12) in its locked position preventing contact with the driving end (2a) of the nut (2) in its rotation movement with the rocker arm (7a) (7).
Como se observa en las figura 1 y 2, cuando la cerradura se encuentra en posición de reposo, al actuar sobre la nueca (2) el extremo de accionamiento (2a) entra en contacto con la pestaña accionadora (7a) del balancín (7) desplazándolo verticalmente. En su desplazamiento la pestaña accionadora (7a) del balancín (7) actúa contra la pestaña (4a) del brazo accionador del picaporte (5), el cual a su vez desplaza horizontalmente el picaporte (5) al actuar el extremo accionador (4b) en el vaciado en " U" del picaporte (5).  As can be seen in figures 1 and 2, when the lock is in the rest position, when acting on the nut (2) the operating end (2a) comes into contact with the actuating flange (7a) of the rocker arm (7) moving it vertically. In its displacement, the actuator flange (7a) of the rocker (7) acts against the flange (4a) of the actuator arm of the latch (5), which in turn displaces the latch (5) horizontally when the actuator end (4b) is actuated. in the "U" emptying of the latch (5).
En la figura 3 y la figura 4 se observa como al actuar sobre el cilindro de cerradura (12) la leva (13) desplaza horizontalmente la palanca (6) a la posición de bloqueo. En dicha posición, el balancín (7) y la campanera (8) vinculados a la palanca (6) se desplazan horizontal y solidariamente impidiendo el contacto del extremo de accionamiento (2a) de la nueca (2) en su desplazamiento de giro con la pestaña accionadora (7a) del balancín (7). In figure 3 and figure 4 it is observed how when acting on the lock cylinder (12) the cam (13) moves the lever (6) horizontally to the locked position. In this position, the rocker (7) and the bell (8) linked to the lever (6) move horizontally and jointly preventing the contact of the drive end (2a) of the nut (2) in its rotation movement with the actuating flange (7a) of the rocker arm (7).
En esta posición se observa co mo e l extre mo d e accionamiento (2a) no puede interactuar con la pestaña accionadora (7a) del balancín (7) impidiendo que el picaporte (5) se retraiga. De este modo, se evita que al aplicar un excesivo par en la manilla se pueda dañar alguna parte del mecanismo interno de la cerradura, o bien que el picaporte (5) se retraiga, pudiendo causar esto u na descolocación de dicho picaporte (5) con respecto a su alojamiento en el marco y la consiguiente pérdida de presión en las juntas intumescentes, que aislan contra el fuego.  In this position, it is observed how the drive end (2a) cannot interact with the actuator flange (7a) of the rocker (7) preventing the latch (5) from retracting. In this way, it is avoided that when applying excessive torque on the handle, some part of the internal mechanism of the lock can be damaged, or that the latch (5) is retracted, which can cause this to be a dislocation of said latch (5) with respect to its housing in the frame and the consequent loss of pressure in the intumescent joints, which isolate against fire.
Otra característica de la invención, como se observa en las figuras 3 y 4 es que al actuar sobre el cilindro de cerradura (12) la leva (13) desplaza la palanca (6) horizontalmente y la cara bloqueante (6a) entra en contacto con la zona activa de bloqueo (5b) del picaporte (5) bloqueándolo e impidiendo que pueda retraerse.  Another feature of the invention, as seen in Figures 3 and 4, is that when acting on the lock cylinder (12) the cam (13) moves the lever (6) horizontally and the blocking face (6a) comes into contact with the active locking zone (5b) of the latch (5) blocking it and preventing it from retracting.
Este bloq ueo de picaporte (5) aseg ura que cuando la palanca (6) se encuentra en posición de bloqueo no pueda darse la retracción del picaporte (5) ante u n i ntento de apertura fraudulenta.  This latch lock (5) ensures that when the lever (6) is in the locked position, the latch retraction (5) cannot occur before a fraudulent opening attempt.
Otra característica de la invención, como se observa en las figuras 5a y 5b, es que la palanca (6) admite dos ejecuciones diferentes, pudiendo disponer de salientes de bloqueo (6b) o carecer de ellos.  Another feature of the invention, as seen in Figures 5a and 5b, is that the lever (6) admits two different executions, being able to have or not have locking projections (6b).
