DESCRIPCIÓNDESCRIPTION

Dispositivo de seguridad para manilla con cerrojo integrado para puerta con cerradura de pestillo y resbalón Integrated Deadbolt Handle Security Device for Door with Latch and Latch Lock

SECTOR DE LA TÉCNICATECHNIQUE SECTOR

La presente invención se refiere a un dispositivo que ha sido especialmente concebido como un elemento de seguridad adicional vinculable a un mecanismo o manilla con cerrojo integrado para puerta con cerradura y resbalón como el descrito en el modelo de utilidad U202230465. The present invention relates to a device that has been specially designed as an additional security element linkable to a mechanism or handle with integrated latch for a door with lock and latch, such as the one described in utility model U202230465.

El objeto de la invención es por tanto incrementar el nivel de seguridad en este tipo de mecanismos, a través de un módulo adicional que activa uno o mas brazos asociados a elementos de cierre/bloqueo verticales, todo ello con una estructuración fácil de instalar y que se acciona automáticamente a través de la misma llave y pestillo que accionaban el mecanismo original, de manera que las maniobras de apertura y cierre no se vean afectadas, manteniendo por tanto la misma sencillez operativa pero incrementando, como se decía, el nivel de seguridad del conjunto. The object of the invention is therefore to increase the level of security in this type of mechanisms, through an additional module that activates one or more arms associated with vertical closing/locking elements, all with a structure that is easy to install and that It is automatically activated through the same key and latch that operated the original mechanism, so that the opening and closing maneuvers are not affected, therefore maintaining the same operational simplicity but increasing, as was said, the level of security of the set.

ANTECEDENTES DE LA INVENCIÓNBACKGROUND OF THE INVENTION

Como es sabido, por motivos de seguridad es habitual instalar elementos de cierre adicional a las cerraduras como pueden ser los clásicos cerrojos. As is known, for security reasons it is common to install additional closing elements to locks, such as classic deadbolts.

Este tipo de dispositivos si bien aportan un mayor nivel de seguridad en el cierre de las puertas, presentan una problemática entre la que caben destacar los siguientes aspectos: Although these types of devices provide a higher level of security when closing the doors, they present a problem among which the following aspects should be highlighted:

• Requieren de una segunda llave, de accionamiento independiente del de la cerradura, lo que supone una pérdida de tiempo y molestias a la hora de identificar cada una de las llaves a utilizar en la apertura de la puerta y activación de ambos cierres. • They require a second key, operated independently of the lock, which represents a loss of time and inconvenience when identifying each of the keys to be used to open the door and activate both locks.

• El bombillo de accionamiento del cerrojo requiere de un mecanizado adicional en la puerta que atraviese ésta, maniobra que resulta complicada de realizar para personas no expertas. • The bolt actuation cylinder requires additional machining on the door that passes through it, a maneuver that is difficult to perform for non-experts.

Si bien se conocen mecanismos en los que se vincula un cerrojo con una cerradura, se trata de mecanismos que no son aplicables a cerraduras con manilla y resbalón, a lo que hay que añadir que se trata de mecanismos desarrollados específicamente para cada tipo de cerradura, de manera que no presentan un carácter universal, es decir no son aplicables a cualquier cerradura existente. Although there are known mechanisms in which a bolt is linked to a lock, these are mechanisms that are not applicable to locks with handles and latches, to which it must be added that these are mechanisms developed specifically for each type of lock, so they do not have a universal character, that is, they are not applicable to any existing lock.

Tratando de obviar esta problemática, el propio solicitante es titular del modelo de utilidad U202230465, en el que se describe una manilla con cerrojo integrado para puerta con cerradura de pestillo y resbalón que partiendo de la estructuración convencional de cualquier manilla para puerta con cerradura en la que participa un pestillo o elemento de bloqueo accionable mediante llave por medio de un bombillo y que incorporan un resbalón accionado internamente por una manilla y exteriormente por dicho bombillo, centra sus características en el hecho de que incluye una pletina de soporte de la manilla a la puerta, dotada de medios de fijación a la cara interna de la puerta en correspondencia con el cuerpo de la cerradura, pletina de soporte en la que se integra un mecanismo de cerrojo, en el que sobre la cara inferior del pasador del cerrojo se establece una cremallera en la que engrana una rueda dentada solidaria a un eje de cuadradillo que encaja en un cajeado de sección cuadrangular previsto en el extremo interior del cilindro del bombillo de la cerradura, de manera que dicho cilindro se remata por su extremidad opuesta o externa en la clásica ranura de inserción de la correspondiente llave de apertura, estando el pasador del cerrojo asistido por el clásico puente que se fija al marco de la puerta. Trying to avoid this problem, the applicant himself is the owner of the utility model U202230465, which describes a handle with an integrated lock for a door with a bolt and latch lock that, based on the conventional structuring of any door handle with a lock in the that involves a latch or locking element that can be operated by a key using a cylinder and that incorporate a latch operated internally by a handle and externally by said cylinder, focuses its characteristics on the fact that it includes a support plate for the handle to the door, provided with fixing means to the internal face of the door in correspondence with the body of the lock, support plate in which a bolt mechanism is integrated, in which a bolt is established on the lower face of the bolt pin. rack in which a toothed wheel integral with a square axis that fits into a recess with a quadrangular section provided at the inner end of the cylinder of the lock cylinder engages, so that said cylinder ends at its opposite or external end in the classic insertion slot for the corresponding opening key, the bolt pin being assisted by the classic bridge that is fixed to the door frame.

De esta manera, se consigue un mecanismo fácil de instalar, en el que se puede aprovechar gran parte de las cerraduras ya existentes, que ofrece un plus de seguridad, sin necesidad de llaves adicionales, lo que lo hace cómodo y rápido de accionar, mecanismo que además permite la liberación y bloqueo de la puerta sin necesidad de llave cuando se precise de un acceso rápido y/o continuado en el que no se precise de altos niveles de seguridad, a través del accionamiento del resbalón accionando la correspondiente manilla, cuando el cerrojo y el pestillo estén desbloqueados. In this way, an easy-to-install mechanism is achieved, in which a large part of the existing locks can be used, which offers extra security, without the need for additional keys, which makes it comfortable and quick to operate, mechanism which also allows the release and locking of the door without the need for a key when quick and/or continuous access is required in which high levels of security are not required, through the activation of the latch by activating the corresponding handle, when the bolt and latch are unlocked.

EXPLICACIÓN DE LA INVENCIÓNEXPLANATION OF THE INVENTION

El dispositivo de seguridad que se preconiza va un paso más allá en el nivel de seguridad que ofrece el mecanismo anteriormente descrito, constituyendo un elemento modular adicional, fácilmente instalable sobre el mismo y que permite disponer de medios de cierre/bloqueo verticales accionables igualmente a través de la llave y pestillo de manera que se mantenga inalterada la sencillez operativa. The safety device that is recommended goes one step further in the level of safety offered by the previously described mechanism, constituting an additional modular element, easily installed on it and that allows for vertical closing/locking means that can also be operated through of the key and latch so that operational simplicity remains unchanged.

Para ello, partiendo de la manilla con cerrojo integrado para puerta con cerradura de pestillo y resbalón que se describe en el modelo de utilidad U202230465, el dispositivo de la invención se constituye a partir de una carcasa adapatable y fijable por atornillamiento, remachado o cualquier otro medio convencional a la pletina de soporte de dicho mecanismo previsto en el modelo de utilidad U202230465, carcasa en la que se define una cámara interna, accesible a través de la correspondiente tapa practicable, cámara en la que es desplazable verticalmente al menos un brazo que se extiende más allá de la carcasa, sobresaliendo a través de una ventana prevista en dicha carcasa, brazo que se vinculará a una falleba asociada al correspondiente medio de bloqueo vertical de la puerta sobre el suelo y/o sobre el marco superior de la puerta, a través de los correspondientes herrajes en los que encajarán dicha falleba o fallebas en posición de bloqueo. To do this, starting from the handle with integrated lock for a door with latch and latch lock that is described in utility model U202230465, the device of the invention is constituted from an adaptable casing and fixable by screwing, riveting or any other conventional means to the support plate of said mechanism provided in the utility model U202230465, housing in which an internal chamber is defined, accessible through the corresponding practicable cover, chamber in which at least one arm that can be moved vertically is extends beyond the casing, protruding through a window provided in said casing, arm that will be linked to a bolt associated with the corresponding vertical locking means of the door on the floor and/or on the upper frame of the door, to through the corresponding hardware in which said latch or latches will fit in the locking position.

De forma más concreta, se ha previsto que el extremo del citado brazo que juega en el seno de la cámara interna de la carcasa del dispositivo incluya un ramal en cuya cara interna se establece una cremallera que es accionada por una rueda dentada que incluye un vaciado central de sección cuadrangular, por el que se hace pasar el vástago o cuadradillo vinculado al cilindro del bombillo de la cerradura que accionaba el pasador del cerrojo. More specifically, it has been planned that the end of said arm that plays within the internal chamber of the housing of the device includes a branch on the internal face of which a rack is established that is driven by a toothed wheel that includes a recess. central quadrangular section, through which the stem or square linked to the cylinder of the lock cylinder that operated the bolt pin is passed.

Tal y como se ha dicho con anterioridad, el dispositivo podría incorporar dos brazos verticales, uno superior y uno inferior, de modo que ambos brazos incluyan sendos ramales con cremalleras de dentados enfrentados, entre los que se dispone la rueda dentada, de modo que la misma rueda pueda accionar de forma simultánea ambos brazos en su desplazamiento de extensión y retracción en función del sentido de giro de la rueda. As previously stated, the device could incorporate two vertical arms, one upper and one lower, so that both arms include separate branches with opposing toothed racks, between which the toothed wheel is arranged, so that the The same wheel can simultaneously operate both arms in their extension and retraction movement depending on the direction of rotation of the wheel.

De esta forma al accionar la llave se accionará de forma simultánea el pasador del cerrojo y el brazo o brazos verticales de accionamiento de los medios de bloqueo verticales, maniobra sincronizada que se puede realizar igualmente al desplazar lateralmente el tirador del pasador del cerrojo, ya que su desplazamiento lateral obligará a girar al cuadradillo del bombillo de la cerradura, y consecuentemente a la rueda que acciona el brazo o brazos verticales del dispositivo. In this way, when the key is operated, the bolt pin and the vertical arm or arms for actuating the vertical locking means will be activated simultaneously, a synchronized maneuver that can also be carried out by laterally moving the handle of the bolt pin, since Its lateral displacement will force the lock cylinder square to rotate, and consequently the wheel that drives the vertical arm or arms of the device.

Opcionalmente, el cuadradillo podría rematarse en correspondencia con la cara interna de la puerta en un pequeño pomo o rueda de accionamiento manual del mismo, de modo que permita el desplazamiento simultáneo de ambos mecanismos sin tener que actuar sobre el tirador del pasador del cerrojo, elemento que con esta solución resulta innecesario, por lo que podría eliminarse. Optionally, the square could be finished in correspondence with the internal face of the door in a small knob or manually operated wheel, so that it allows the simultaneous movement of both mechanisms without having to act on the handle of the bolt bolt, element which with this solution is unnecessary, so it could be eliminated.

Solo resta señalar por último que, la carcasa incorporará un orificio para paso de la correspondiente manilla de accionamiento del pestillo de la puerta, de modo que ésta no interfiera en dicho accionamiento, permitiendo tener la puerta cerrada con el cerrojo y brazos verticales desbloqueados en base al mecanismo del pestillo cuando se precise de un acceso rápido y/o continuado en el que no se precise de altos niveles de seguridad, lo que lo hace cómodo de usar, ya que no es preciso tener que recurrir siempre a las llaves para abrir la puerta cuando por ejemplo, se pretenden introducir múltiples objetos (compras, mudanzas, etc), o se prevé el acceso de múltiples personas (reuniones, fiestas, etc). Lastly, it only remains to be noted that the casing will incorporate a hole for the passage of the corresponding handle to operate the door latch, so that it does not interfere with said operation, allowing the door to be closed with the bolt and vertical arms unlocked at the base. to the latch mechanism when quick and/or continuous access is required in which high levels of security are not required, which makes it convenient to use, since it is not necessary to always have to resort to the keys to open the door. door when, for example, you intend to introduce multiple objects (shopping, moving, etc.), or the access of multiple people is anticipated (meetings, parties, etc.).

A partir de esta estructuración se consigue un mecanismo adicional de seguridad fácilmente aplicable al mecanismo descrito en el modelo de utilidad U202230465, sencillo de instalar y que no complica ni modifica las maniobras de accionamiento de los diferentes mecanismos de seguridad previstos en el conjunto. From this structure, an additional security mechanism is achieved that is easily applicable to the mechanism described in the utility model U202230465, easy to install and that does not complicate or modify the operation maneuvers of the different security mechanisms provided in the set.

REALIZACIÓN PREFERENTE DE LA INVENCIÓNPREFERRED EMBODIMENT OF THE INVENTION

A la vista de las figuras reseñadas, y en especial de la figura 1, puede observarse como el dispositivo de la invención es aplicable a manillas con cerrojo integrado para puertas con cerradura como la prevista en el modelo de utilidad U202230465 en la que participa una manilla (1) de accionamiento de un resbalón, a la que se vincula una pletina de soporte (2), dotada de medios de fijación a la cara interna de la puerta en correspondencia con el cuerpo de la cerradura, pletina de soporte (2) en la que se integra un mecanismo de cerrojo, en el que sobre la cara inferior del pasador (3) del cerrojo se establece una cremallera en la que engrana un piñón (4) solidario a un eje de cuadradillo que encaja en un cajeado (5) de sección cuadrangular previsto en el extremo interior del cilindro del bombillo de la cerradura, cilindro que se remata por su extremidad opuesta o externa en la clásica ranura de inserción de la correspondiente llave de apertura, estando, como es convencional el pasador (3) del cerrojo asistido por puente en el que encaja lateralmente el pasador del cerrojo, dotado de medios de fijación al marco de la puerta, elemento que no aparece representado en las figuras, por ser convencional. In view of the figures outlined, and especially Figure 1, it can be seen how the device of the invention is applicable to handles with an integrated bolt for doors with locks such as the one provided in the utility model U202230465 in which a handle participates. (1) for actuating a latch, to which a support plate (2) is linked, provided with means of fixing to the internal face of the door in correspondence with the body of the lock, support plate (2) in which integrates a bolt mechanism, in which a rack is established on the lower face of the pin (3) of the bolt in which a pinion (4) engages integrally with a square axis that fits into a recess (5) of quadrangular section provided at the inner end of the cylinder of the lock cylinder, cylinder that ends at its opposite or external end in the classic insertion slot of the corresponding opening key, being, as is conventional, the pin (3) of the bridge-assisted bolt in which the bolt pin fits laterally, provided with means of fixing to the door frame, an element that is not represented in the figures, as it is conventional.

Pues bien, de acuerdo ya con la invención, y como se puede observar en la figura 2, el dispositivo de la invención se constituye a partir de una carcasa (6) de dimensiones en planta acordes a la pletina de soporte (2) sobre la que está destinada a fijarse a través de orificios de atornillamiento (7), remachado, o cualquier otro medio convencional. Well, according to the invention, and as can be seen in Figure 2, the device of the invention is constituted from a casing (6) with dimensions in plan according to the support plate (2) on the which is intended to be fixed through screw holes (7), riveting, or any other conventional means.

La carcasa (6) presentará por tanto una configuración alargada verticalmente, definiéndose una cámara interna (8) obturable mediante una tapa (9) contando en al menos uno de sus extremos, preferentemente en el extremo inferior, con una ventana (10) de la que emerge un brazo (11) desplazable verticalmente, y que se vinculará a través de los correspondientes medios (12) a una falleba o barra de bloqueo vertical, no representada en las figuras por ser un elemento convencional de mercado, que estará asistida, como también es convencional, por unos herrajes de fijación al suelo y/o al marco superior de la puerta. The housing (6) will therefore have a vertically elongated configuration, defining an internal chamber (8) that can be closed by means of a cover (9) with at least one of its ends, preferably at the lower end, with a window (10) of the a vertically movable arm (11) emerges, and which will be linked through the corresponding means (12) to a vertical locking bar or bolt, not represented in the figures because it is a conventional market element, which will be assisted, as It is also conventional, with fixing hardware to the floor and/or the upper frame of the door.

Para accionar el brazo (11), se ha previsto que el mismo se remate en un ramal (13), dotado de una cremallera (14) sobre su cara interna, que es desplazable verticalmente por medio de una rueda dentada (15) susceptible de girar establemente en el seno de la carcasa (8), y que incluye un vaciado o cajeado de sección cuadrangular (5’) de forma análoga al cajeado (5) del mecanismo principal, al que queda enfrentado en su montaje, de modo que a través de ambos cajeados (5-5’) se hace pasar un cuadradillo vinculado al cilindro del bombillo de la cerradura que accionaba el pasador del cerrojo y que se remata en la ranura de inserción de la correspondiente llave, de manera que al accionar la llave se desplace sincronizadamente tanto el pasador (3) del cerrojo en sentido horizontal como el brazo (11) de bloqueo en sentido vertical. To operate the arm (11), it is planned that it ends in a branch (13), equipped with a rack (14) on its internal face, which is movable vertically by means of a toothed wheel (15) capable of rotate stably within the casing (8), and which includes a hollow or recess with a quadrangular section (5') analogous to the recess (5) of the main mechanism, which is faced in its assembly, so that Through both recesses (5-5') a square is passed linked to the cylinder of the lock cylinder that operated the bolt pin and ends in the insertion slot of the corresponding key, so that when the key is actuated Both the bolt pin (3) of the bolt moves horizontally and the locking arm (11) moves synchronously in a vertical direction.

Paralelamente, y en virtud de la estructuración descrita, al accionar manualmente el pasador (3) a través de su correspondiente tirador, éste hará girar a través de su cremallera el cuadradillo de accionamiento de ambas ruedas dentadas, y consecuentemente provocará el desplazamiento sincronizado en uno u otro sentido del brazo (11) de bloqueo de acuerdo con las dos posiciones extremas operativas mostradas en las figuras 2 y 3. In parallel, and by virtue of the described structure, when manually operating the pin (3) through its corresponding handle, it will rotate the drive square of both gear wheels through its rack, and consequently will cause synchronized displacement in one or another direction of the locking arm (11) according to the two extreme operating positions shown in Figures 2 and 3.

No obstante, el cuadradillo podría rematarse en correspondencia con la cara interna de la puerta, es decir en oposición a la ranura de inserción de la llave, en un pequeño pomo o rueda de accionamiento manual de modo que permita el desplazamiento simultáneo de ambos mecanismos sin tener que actuar sobre el tirador del pasador del cerrojo, pudiéndose prescindir de dicho tirador. However, the square could be finished in correspondence with the internal face of the door, that is, in opposition to the slot for inserting the key, in a small knob or manually operated wheel so that it allows the simultaneous movement of both mechanisms without having to act on the handle of the bolt pin, being able to do without said handle.

Esta solución resulta más segura ante una situación de riesgo, ya que además de resultar una solución más intuitiva, no precisa de actuar sobre la llave, ya que el propio bombillo actúa sobre el resbalón. This solution is safer in a risky situation, since in addition to being a more intuitive solution, it does not require acting on the key, since the cylinder itself acts on the latch.

En cuanto al bombillo, y en contra de las dos posibilidades que se barajaban en el modelo de utilidad U202230465, en el presente caso este deberá ser siempre de doble embrague. As for the cylinder, and contrary to the two possibilities that were considered in the utility model U202230465, in this case it must always be double clutch.

De acuerdo con la variante de realización mostrada en la figura 4, el dispositivo es susceptible de incorporar dos brazos (11-11’) de bloqueo vertical, uno superior y otro inferior, de modo que ambos brazos incluyan sendos ramales (13) con sus correspondientes cremalleras (14) enfrentadas a uno y otro lado de la rueda dentada (15), de modo que la misma rueda puede accionar de forma simultánea ambos brazos en su desplazamiento de extensión y retracción en función del sentido de giro de la rueda. According to the embodiment variant shown in Figure 4, the device is capable of incorporating two vertical locking arms (11-11'), one upper and one lower, so that both arms include separate branches (13) with their corresponding racks (14) facing each other of the toothed wheel (15), so that the same wheel can simultaneously operate both arms in its extension and retraction movement depending on the direction of rotation of the wheel.

Para ello, el brazo (11’) superior incluirá una ventana alargada (21) determinante de dos largueros (17) pasantes a través de orificios de guiado (18) previstos en la carcasa (6), ventana que permite el desplazamiento vertical del brazo sin interferir en eje (20) de la manilla (1) jugando el extremo de dicha manilla (1) en un cajeado circular (19) visible en las figuras 2 a 4. To do this, the upper arm (11') will include an elongated window (21) determining two stringers (17) passing through guide holes (18) provided in the housing (6), a window that allows the vertical movement of the arm. without interfering with the axis (20) of the handle (1), playing the end of said handle (1) in a circular recess (19) visible in figures 2 to 4.
