Description

CILINDRO MOTORIZADO PARA CERRADURA DE SEGURIDAD MOTORIZED CYLINDER FOR SAFETY LOCK
OBJETO DE LA INVENCIÓN.OBJECT OF THE INVENTION
La siguiente invención, según se expresa en el enunciado de la presente memoria descriptiva, se refiere a un cilindro motorizado para cerradura de seguridad, cuya finalidad consiste en proporcionar un sistema para la apertura automática de cerraduras por medio de la motorización del dispositivo de cilindros, pudiéndose incorporar en las cerraduras ya existentes con cilindro de perfil europeo de accionamiento manual mediante llave, que actúan sobre puertas peatonales, tanto domésticas como de otros usos, donde es necesario tener en cuenta los niveles de seguridad y estéticos exigibles, así como la previsión de medios para que el dispositivo motorizado de cilindros se pueda utilizar, según las posibles versiones, tanto de montaje como de instalación, de las cerraduras de seguridad en puertas convencionales, permitiendo la integración de la puerta en un sistema de control de accesos mediante mandos a distancia, lectores de tarjeta y de proximidad, teclados y otros medios electrónicos de una forma rápida y fiable.The following invention, as expressed in the statement of the present specification, refers to a motorized cylinder for security lock, the purpose of which is to provide a system for the automatic opening of locks by means of the motorization of the cylinder device, being able to incorporate in the existing locks with a European profile cylinder with manual operation by means of a key, which act on pedestrian doors, both domestic and other, where it is necessary to take into account the required safety and aesthetic levels, as well as the provision of means so that the motorized cylinder device can be used, according to the possible versions, both assembly and installation, of the security locks on conventional doors, allowing the integration of the door into an access control system by means of remote controls , card and proximity readers, keyboards and other elec media tronics in a fast and reliable way.
Además, el dispositivo de cilindro motorizado propuesto está previsto para funcionar en las cerraduras tanto de cerradero que tienen un resbalón y/o un cerrojo, como en las de tipo multipunto.In addition, the proposed motorized cylinder device is intended to operate in both locks of the locks that have a slip and / or a bolt, as in those of the multipoint type.
Así, dicho cilindro motorizado para cerradura de seguridad permite el accionamiento manual de la cerradura en la que se ha incorporado, por un lado, por ejemplo el lado exterior, con la ayuda de una llave, y, por el otro lado, por medios motores.Thus, said motorized cylinder for safety lock allows manual operation of the lock in which it has been incorporated, on the one hand, for example the outer side, with the help of a key, and, on the other hand, by motor means .
La particularidad está en la necesidad de separar ambos accionamientos para evitar funcionamientos incorrectos, manteniendo los criterios de seguridad y estéticos y con capacidad para permitir la apertura y cierre del resbalón y de uno o varios cerrojos de la cerradura mediante la motorización del cilindro.The particularity is the need to separate both drives to avoid malfunctions, maintaining the safety and aesthetic criteria and with the capacity to allow the opening and closing of the slip and one or more locks of the lock by means of the motorization of the cylinder.
La separación de ambos accionamientos se realiza mediante un sistema convencional de embrague de los utilizados para el accionamiento manual de las cerraduras, ventajosamente adaptado para funcionar en el cilindro motorizado. Estos sistemas de embrague convencional, tienen la particularidad de trabajar en reposo, ya que, son utilizados en algunas cerraduras de accionamiento manual, por ambos lados del cuerpo de cilindro a través de una llave, que permite el giro de los cilindros internos, montados de manera giratoria en el cilindro externo que forma el cuerpo, de manera independiente entre ellos según su accionamiento por medio de la llave, para su movimiento giratorio de acoplamiento con una leva a través de dos piezas de embrague con chavetas de arrastre y sin separación entre éstas, con movimiento relativo lineal en el eje longitudinal de los cilindros, dentro de la zona circular de acoplamiento con la leva y con transmisión a ésta del movimiento de giro por medio de los dos cilindros internos, estando la leva conectada al pestillo y/o cerrojos de la cerradura.The separation of both drives is carried out by means of a conventional clutch system of those used for the manual operation of the locks, advantageously adapted to operate in the motorized cylinder. These conventional clutch systems have the particularity of working at rest, since, they are used in some manually operated locks, on both sides of the cylinder body through a key, which allows the rotation of the internal cylinders, rotatably mounted on the external cylinder that forms the body, independently of each other according to its actuation by means of the key, for its rotating coupling movement with a cam through two clutch parts with drag keys and without separation between them, with linear relative movement on the shaft longitudinal of the cylinders, within the circular zone of coupling with the cam and with transmission to it of the turning movement by means of the two internal cylinders, the cam being connected to the latch and / or locks of the lock.
Este sistema de embrague está caracterizado por permitir que el acoplamiento de las chavetas de arrastre de los embragues sobre la leva, por el lado de uno u otro cilindro, sea posible independientemente de la posición relativa entre ambos cilindros y de la posición de la leva respecto de ellos, por medio de un resorte que fuerza a los embragues hacia sus posiciones de unión, es decir, hacia la leva, y que al mismo tiempo permite la introducción de la llave por uno u otro cilindro interno y su posterior giro, con lo que dicho resorte es cargado para forzar a los embragues a sus respectivas posiciones antes mencionadas.This clutch system is characterized by allowing the coupling of the clutches of the clutches on the cam, on the side of one or the other cylinder, to be possible regardless of the relative position between both cylinders and the position of the cam relative to of them, by means of a spring that forces the clutches towards their joining positions, that is, towards the cam, and that at the same time allows the introduction of the key by one or another internal cylinder and its subsequent rotation, with that said spring is loaded to force the clutches to their respective positions mentioned above.
Un objeto de la presente invención es permitir el acoplamiento de las chavetas de arrastre de los embragues de ambos cilindros giratorios sobre la leva independientemente de la posición relativa de los cilindros y de la leva, teniendo en cuenta que en este caso uno de los cilindros está acoplado de forma permanente a un sistema de motorización y el otro cilindro es accionado por un sistema convencional de llave, tratándose por tanto, de un embrague no de reposo debido al sistema de motorización acoplado a uno de los cilindros.An object of the present invention is to allow the coupling of the driving keys of the clutches of both rotating cylinders on the cam regardless of the relative position of the cylinders and the cam, taking into account that in this case one of the cylinders is permanently coupled to a motorization system and the other cylinder is driven by a conventional key system, thus being a non-resting clutch due to the motorization system coupled to one of the cylinders.
Debido a la particularidad de la motorización de uno de los cilindros internos y el accionamiento del otro por medio de una llave, es necesario adaptar este sistema de embrague, ya que, su funcionamiento ya no es en reposo. De esta forma, es posible la introducción de la llave por un lado estando el otro con movimiento de giro debido a la motorización, con lo que existiría riesgo de lesión ó de fallo del mecanismo. Esta cuestión es solucionada mediante la separación entre las chavetas de arrastre de ambas piezas de embrague con lo que se logra un espacio de punto muerto, previo al acoplamiento del embrague de la zona de accionamiento manual mediante llave con la leva.Due to the particularity of the motorization of one of the internal cylinders and the actuation of the other by means of a key, it is necessary to adapt this clutch system, since its operation is no longer at rest. In this way, it is possible to introduce the key on one side, the other being in a turning movement due to the motorization, which would result in a risk of injury or failure of the mechanism. This issue is solved by separating the drag keys of both clutch parts, thereby achieving a neutral space, prior to the clutch coupling of the manually operated area by means of a key with the cam.
Además, el accionamiento manual alternativo por el lado de la motorización, se ha tenido en cuenta en previsión de la posibilidad de la actuación manual del cilindro desde el lado interior.In addition, the alternative manual drive on the motor side has been taken into account in anticipation of the possibility of manual actuation of the cylinder from the inner side.
Por otra parte, los niveles de seguridad exigidos se logran por medio de una placa base que protege a los medios motores y que prevé la protección de los hilos de control del motor por medio del acoplamiento de una conducción blindada hasta el extremo de la hoja de la puerta, hasta su límite en la zona de las bisagras, y dicha placa base está construida de forma que permite el amarre de un escudo convencional de seguridad en el exterior de la puerta utilizado para la protección del cilindro de la cerradura.On the other hand, the required safety levels are achieved by means of a base plate that protects the motor means and that provides for the protection of the motor control wires by means of the coupling of an armored conduit to the end of the sheet of the door, to its limit in the area of the hinges, and said base plate is constructed in such a way that it allows the mooring of a conventional security shield on the outside of the door used for the protection of the lock cylinder.
Asimismo, los niveles estéticos alcanzados son apropiados para los entornos de tipo doméstico y se logran mediante la construcción de un marco en previsión de los inconvenientes estéticos derivados de la posibilidad de instalación del cilindro motorizado en diferentes espesores de puerta, lo que permite la utilización de un único cilindro de longitud fija. También se ha tenido muy en cuenta el nivel estético exigido en el diseño del volante para accionamiento alternativo manual por el lado de la motorización, el cual se ha fijado sin necesidad de tornillos ni elementos de fijación visibles.Likewise, the aesthetic levels achieved are appropriate for domestic environments and are achieved through the construction of a framework in anticipation of aesthetic inconveniences arising from the possibility of installing the motorized cylinder in different door thicknesses, which allows the use of a single fixed length cylinder. It has also taken into account the aesthetic level required in the design of the handwheel for manual alternative drive by the side of the motorization, which has been fixed without the need for visible screws or fasteners.
Otras cuestiones estéticas, relacionadas con diferentes posibilidades de sustitución del cilindro motorizado por el convencional de la cerradura, según las variantes de manillas interiores existentes, se han tenido en cuenta en la presente invención.Other aesthetic issues, related to different possibilities of replacing the motorized cylinder with the conventional one of the lock, according to the variants of existing interior handles, have been taken into account in the present invention.
CAMPO DE APLICACIÓN. El cilindro motorizado para cerradura de seguridad que se presenta es de especial aplicación para la apertura automática de puertas peatonales, tanto domésticas como de otros usos, mediante la sustitución del cilindro convencional de accionamiento manual de la cerradura por el cilindro motorizado objeto de la invención, teniendo en cuenta los niveles de seguridad y estéticos exigibles.

The internal cylinder to which the motorization system is coupled, allows its clutch to be permanently coupled to the cam, by rotating the motor, by means of a spring, so that the introduction of the key, through the other internal cylinder, originates the decoupling of the clutch from the internal cylinder coupled to the motorization system due to the drive made by the key on the clutch through a pivot-axis.
Para permitir que el embrague del cilindro interno del lado de accionamiento manual mediante llave pueda ser acoplado a la leva, existe un resorte que fuerza a un embrague a juntarse con el otro axialmente sobre el pivote-eje, para prevenir la interferencia del embrague del cilindro interno de la llave con la leva por no coincidencia con el alojamiento de acoplamiento, lo que además de permitir la correcta posición de la llave en el cilindro interno, permite mediante el giro de dicho cilindro interno la coincidencia del embrague con el alojamiento de acoplamiento en la leva y el acoplamiento es originado por la carga previa del resorte mencionado del embrague debido a la interferencia con la leva al ser impulsado el embrague del cilindro interno del sistema de motorización por medio de la llave a través del pivote-eje mencionado. De esta manera el accionamiento por llave siempre es permitido con independencia del sistema de motorización y de las posiciones relativas de cilindros internos y la leva.In order to allow the clutch of the internal cylinder of the manually operated side by key to be coupled to the cam, there is a spring that forces one clutch to join the other axially on the pivot-axis, to prevent interference of the cylinder clutch internal of the key with the cam for not coinciding with the coupling housing, which in addition to allowing the correct position of the key in the internal cylinder, allows by turning said internal cylinder the coincidence of the clutch with the coupling housing in the cam and the coupling is caused by the previous loading of the mentioned clutch spring due to interference with the cam when the clutch of the internal cylinder of the motorization system is driven by means of the key through the mentioned pivot-axis. In this way the key drive is always allowed regardless of the motorization system and of the relative positions of internal cylinders and cam.
Dichos embragues, con resorte y pivote-eje, de impulsión mediante llave, son acoplados en la leva según su coincidencia con el alojamiento de acoplamiento en la misma, donde un resorte impulsa de forma permanente al embrague del cilindro interno de motorización y permite su acoplamiento en la leva, por medio del giro del motor, y donde el resorte de los embragues y el pivote de impulsión del embrague del cilindro interno de accionamiento por llave, permite el accionamiento por medio de la llave en caso de interferencia del embrague del cilindro interno de la llave con el alojamiento de acoplamiento de la leva, donde ambos embragues se encuentran convenientemente separados para permitir un estado de punto muerto en previsión de una situación de no interferencia del embrague del cilindro interno de la llave con el alojamiento de acoplamiento de la leva.Said clutches, with spring and pivot-axis, of key drive, are coupled in the cam according to their coincidence with the coupling housing therein, where a spring permanently drives the clutch of the internal motorization cylinder and allows its coupling on the cam, by means of the rotation of the engine, and where the clutch spring and the clutch drive pivot of the internal key-operated cylinder, allows the actuation by means of the key in case of interference of the internal cylinder clutch of the key with the cam coupling housing, where both clutches are conveniently separated to allow a neutral state in anticipation of a non-interference situation of the clutch of the internal cylinder of the key with the cam coupling housing .
Dichos cilindros internos se encuentran dentro de un cuerpo de cilindro externo de perfil europeo y de funcionamiento dentro de una cerradura de seguridad, cuyo cilindro interno de motorización se encuentra acoplado a un conjunto de sistema reductor con un motor eléctrico, con lo que dicho conjunto se encuentra encarado a uno de los lados del cuerpo de cilindro externo, normalmente en el lado interior de la cerradura de la puerta.Said internal cylinders are located within an external cylinder body of European profile and operating within a safety lock, whose internal motorization cylinder is coupled to a reduction system assembly with an electric motor, whereby said assembly is It faces one of the sides of the outer cylinder body, usually on the inner side of the door lock.
La integración del cilindro externo y del conjunto de sistema reductor en la puerta se lleva a cabo por medio de una placa base que protege tanto al motor como a los hilos de control a través de la hoja de la puerta y que permite la sujeción de un escudo protector del cilindro por el lado exterior de la puerta, preferentemente el escudo convencional de la cerradura existente.The integration of the external cylinder and the reduction system assembly in the door is carried out by means of a base plate that protects both the motor and the control threads through the door leaf and allows the attachment of a protective shield of the cylinder on the outer side of the door, preferably the conventional shield of the existing lock.
La integración del conjunto en la puerta, permite por medio de un marco, la utilización de un único cilindro externo para puertas de diferentes espesores, con lo que dicho marco absorbe las inconveniencias estéticas de los montajes sobre diferentes espesores de puerta. Este marco puede ser para integración del sistema respetando la manilla existente en la cerradura o para la integración mediante una manilla propia del sistema de cilindro motorizado objeto de la presente invención.The integration of the assembly into the door allows, through a frame, the use of a single external cylinder for doors of different thicknesses, thereby absorbing the aesthetic inconveniences of the assemblies on different door thicknesses. This frame can be for system integration respecting the handle existing in the lock or for integration using a handle of the motorized cylinder system object of the present invention.
Asimismo, para mejorar la funcionalidad del sistema, manteniendo los criterios estéticos, se han previsto medios para un accionamiento manual alternativo desde el interior, por medio de un volante. Dicho volante se encuentra con giro solidario al cilindro interno del lado de la motorización por medio de un eje con extremo de acoplamiento de giro y está sujeto por medio de un pasador radialmente insertado en el eje de acoplamiento del volante y forzado por un pequeño resorte hacia una garganta circular en el interior del volante, con lo que la interferencia entre el pasador y la garganta, permiten la sujeción del volante en el eje y siendo dicho pasador accesible por medio de un pequeño orificio en el exterior del volante a través de una aguja o similar para la extracción y colocación del volante, con lo que la sujeción se lleva a cabo sin tornillos o elementos de fijación visibles en el volante.Likewise, in order to improve the functionality of the system, while maintaining the aesthetic criteria, means are provided for an alternative manual drive from the inside, by means of a steering wheel. Said flywheel is integral with the internal cylinder on the motor side by means of an axis with a turning coupling end and is secured by means of a pin radially inserted in the flywheel coupling shaft and forced by a small spring towards a circular throat inside the steering wheel, whereby the interference between the pin and the throat, allows the steering wheel to be held on the shaft and said pin being accessible by means of a small hole outside the steering wheel through a needle or similar for the removal and placement of the steering wheel, whereby the fastening is carried out without screws or fasteners visible on the steering wheel.

DESCRIPCIÓN DE UNA REALIZACIÓN PREFERENTE. A la vista de las comentadas figuras y de acuerdo con la numeración adoptada podemos observar como el dispositivo de cilindro motorizado queda integrado en una puerta 14, de forma que el cuerpo 1 de cilindro de perfil europeo del sistema de cilindro motorizado, sustituye al cilindro existente sobre la cerradura 25 convencional. Dicho cuerpo de cilindro externo 1 incluye dos cilindros internosDESCRIPTION OF A PREFERRED EMBODIMENT. In view of the aforementioned figures and according to the numbering adopted we can see how the motorized cylinder device is integrated in a door 14, so that the European profile cylinder body 1 of the motorized cylinder system replaces the existing cylinder on the conventional lock 25. Said external cylinder body 1 includes two internal cylinders
2 y 3 giratorios para accionamiento manual mediante una llave 12 desde el exterior y para accionamiento motorizado desde el interior. Ambos cilindros internos 2 y 3 están diseñados para acoplamiento con una leva 4 conectada a los pestillos y cerrojos de la cerradura 25 por medio de dos piezas de embrague 5 y 6 provistas de chavetas de arrastre 7 y 8 como se detalla en la figura 3 de los diseños, con acoplamiento independiente en los alojamientos de la leva 4 y accionadas de manera giratoria mediante los cilindros internos 2 y 3 de accionamiento manual mediante llave o accionamiento por acoplamiento a un sistema motorizado, respectivamente.2 and 3 swivels for manual operation by means of a key 12 from the outside and for motorized drive from the inside. Both internal cylinders 2 and 3 are designed for coupling with a cam 4 connected to the latches and bolts of the lock 25 by means of two clutch parts 5 and 6 provided with drag keys 7 and 8 as detailed in Figure 3 of the designs, with independent coupling in the housings of the cam 4 and rotatably operated by means of the internal cylinders 2 and 3 of manual operation by means of a key or drive by coupling to a motorized system, respectively.
Dicho cilindro interno 3 de motorización se encuentra acoplado a un conjunto de sistema reductor 24 con un motor eléctrico 16 por medio del eje 21, con lo que dicho conjunto 24 se encuentra encarado a uno de los lados del cuerpo de cilindro externo 1, normalmente, en el lado interior de la puerta 14.Said internal motoring cylinder 3 is coupled to a reduction system assembly 24 with an electric motor 16 by means of the axis 21, whereby said assembly 24 faces one of the sides of the external cylinder body 1, normally, on the inner side of the door 14.
El resorte 10 del embrague 6 de acoplamiento del cilindro interno 3 motorizado, mantiene a aquél en la posición permanente de acoplamiento con la leva 4. Únicamente, mediante la introducción de la llave 12, a través del cilindro interno 2 de accionamiento manual, el embrague 6 de acoplamiento del cilindro interno 3 motorizado es desacoplado de la leva 4.The spring 10 of the coupling clutch 6 of the motorized internal cylinder 3 keeps the latter in the permanent position of coupling with the cam 4. Only, by inserting the key 12, through the internal cylinder 2 of manual operation, the clutch 6 coupling of the motorized internal cylinder 3 is disengaged from cam 4.
El acoplamiento a la leva 4 del embrague 5 del cilindro interno 2 de accionamiento manual, se realiza por medio de un resorte 9 que trabaja entre una superficie plana interior del embrague 5 y la superficie plana de tope del pivote-eje 11, con lo que la introducción de la llave 12, en caso de interferencia del embrague 5 con la leva 4, es permitida por medio de la carga del resorte 9 y el giro del cilindro interno 2 junto con el embrague 5 también es permitido, con lo que el acoplamiento del embrague 5 en la leva 4 se produce por la fuerza del resorte 9 cargado, al coincidir la chaveta de arrastre 7 del embrague 5 con su alojamiento sobre la leva 4.The coupling to the cam 4 of the clutch 5 of the internal cylinder 2 of manual actuation is carried out by means of a spring 9 that works between an inner flat surface of the clutch 5 and the flat abutment surface of the pivot-axis 11, whereby the introduction of key 12, in case of interference of the clutch 5 with the cam 4, it is allowed by means of the loading of the spring 9 and the rotation of the internal cylinder 2 together with the clutch 5 is also allowed, whereby the clutch coupling 5 on the cam 4 it is produced by the force of the loaded spring 9, when the driving key 7 of the clutch 5 coincides with its housing on the cam 4.
Una separación entre las chavetas de arrastre 7 y 8 de ambos embragues 5 y 6, tal y como se detalla en la figura 3 de los diseños, prevé la no interferencia del primero con la leva 4, en caso de introducción de la llave 12, con lo que un estado de punto muerto se da tras el desacoplo del embrague 6 del cilindro interno 3 motorizado previo al acoplamiento manual del embrague 5.A separation between the cotter pins 7 and 8 of both clutches 5 and 6, as detailed in Figure 3 of the designs, foresees the non-interference of the first with the cam 4, in case of introduction of the key 12, whereby a neutral state occurs after decoupling the clutch 6 from the motorized internal cylinder 3 prior to manual clutch engagement 5.
Tal y como se representa en la figura 1 adjunta, el cilindro interno 2 de accionamiento manual, por el lado exterior de la puerta 14, es protegido mediante un escudo 13 sujetado mediante tornillos a la placa base 15 del dispositivo de cilindro motorizado. Dicha placa base 15 incluye una zona de protección 15a del motor 16 conectada a una conducción blindada 17 que atraviesa la puerta 14, para proteger a los hilos de control del motor 16, pudiendo observar dicha conducción blindada 17 en la figura 2 de los diseños, y la cual esta conectada a la zona de protección 15a del motor 16.As shown in the attached figure 1, the manually operated internal cylinder 2, on the outer side of the door 14, is protected by a shield 13 fastened by screws to the base plate 15 of the motorized cylinder device. Said base plate 15 includes a protection zone 15a of the motor 16 connected to an armored conduit 17 that passes through the door 14, to protect the control threads of the motor 16, said armored conduction 17 being able to be observed in Figure 2 of the designs, and which is connected to the protection zone 15a of the motor 16.
Mediante el marco 18, representado en la figura 1, es posible la utilización de un único cilindro externo 1 de longitud fija para la integración del sistema en puertas de diferentes espesores. Por otra parte, el marco 18 puede presentar diferentes diseños, y, así, puede tener diferente altura, corta o larga, en función de si se quiere o no mantener la manilla original 19 de la cerradura, tal y como se ha representado en la figura 2.By means of the frame 18, represented in figure 1, it is possible to use a single external cylinder 1 of fixed length for the integration of the system into doors of different thicknesses. On the other hand, the frame 18 can have different designs, and thus, can have different height, short or long, depending on whether or not to keep the original handle 19 of the lock, as represented in the figure 2.
También es posible el accionamiento manual desde el interior por medio de un volante 20, con lo que los cerrojos y el pestillo pueden ser retirados. Este volante 20, representado en la sección de la figura 1, se encuentra sujeto al eje 21 de acoplamiento al cilindro interno 3 de motorización por medio de un pasador 22 radialmente insertado en el eje 21 de acoplamiento del volante 20 y forzado por un pequeño resorte 23 hacia una garganta circular 20a en el interior del volante 20, con lo que la interferencia entre el pasador 22 y la garganta 20a del volante 20, permite la sujeción de éste en el eje 21, siendo dicho pasador 22 accesible por medio de un pequeño orificio 20b en el exterior del volante 20 para la extracción y colocación del mismo. En la figura 3 está representado el conjunto formado por los embragues 5 y 6 de acoplamiento del cilindro interno 2 de accionamiento mediante llave 12 y el cilindro interno 3 de accionamiento motorizado, donde se puede observar el pivote-eje 11 sobre el que giran. Asimismo, es apreciable la separación existente entre las chavetas de arrastre 7 y 8 de las piezas de embrague 5 y 6, a fin de garantizar un estado de punto muerto.Manual operation from the inside is also possible by means of a handwheel 20, whereby the bolts and the latch can be removed. This steering wheel 20, represented in the section of figure 1, is attached to the coupling shaft 21 to the internal motoring cylinder 3 by means of a pin 22 radially inserted in the coupling shaft 21 of the steering wheel 20 and forced by a small spring 23 towards a circular throat 20a inside the steering wheel 20, with that the interference between the pin 22 and the throat 20a of the flywheel 20, allows it to be held on the shaft 21, said pin 22 being accessible by means of a small hole 20b on the outside of the flywheel 20 for the removal and placement thereof . Figure 3 shows the assembly formed by the coupling clutches 5 and 6 of the internal cylinder 2 by means of a key 12 and the internal cylinder 3 of the motorized drive, where the pivot-axis 11 on which they rotate can be seen. Likewise, the separation between the drag keys 7 and 8 of the clutch parts 5 and 6 is appreciable, in order to guarantee a neutral state.
En la vista en sección de la figura 4 se puede apreciar el resorte cónico interior 9 de la figura 1 para el acoplamiento del embrague 5 del cilindro interno 2 de accionamiento manual con la leva 4 y la posibilidad de introducción de la llave 12 en dicho cilindro interno 2 para el giro del mismo. El pivote-eje 11 tiene unas superficies de tope en su eje para garantizar el giro de las piezas de embrague 5 y 6 sobre él.In the sectional view of Figure 4, the inner conical spring 9 of Figure 1 can be seen for coupling the clutch 5 of the manually operated internal cylinder 2 with the cam 4 and the possibility of introducing the key 12 into said cylinder internal 2 for its rotation. The pivot-axis 11 has stop surfaces on its axis to guarantee the rotation of the clutch parts 5 and 6 thereon.
En las figuras 3 y 4 se puede observar que ambos embragues 5 y 6 tienen distinto número de chavetas de arrastre 7 y 8, con lo que su acoplamiento sobre la leva 4 se realiza de forma diferente, principalmente, debido a que es necesario restringir a una única posición las posibilidades de acoplamiento del embrague 5 del cilindro interno 2 de accionamiento mediante llave 12 con los alojamientos de la leva 4, para un correcto funcionamiento mediante llave 12. In Figures 3 and 4 it can be seen that both clutches 5 and 6 have different numbers of drag keys 7 and 8, whereby their coupling on cam 4 is carried out differently, mainly, because it is necessary to restrict In a single position, the coupling possibilities of the clutch 5 of the internal cylinder 2 operated by means of a key 12 with the housings of the cam 4, for a correct operation by means of a key 12.
