Description

DESCRIPCIONDESCRIPTION

Dispositivo para proteger cerraduras.Device to protect locks.

La presente invencion se refiere a un dispositivo para proteger cerraduras.The present invention relates to a device for protecting locks.

Actualmente se conocen cerraduras que estan adaptadas para permitir el cierre y la apertura de una puerta o de una verja, que comprenden, esencialmente, un cilindro de apertura provisto de un asiento para insertar una llave adecuada que esta adaptada para permitir la activacion del cilindro y, por tanto, el desbloqueo de la cerradura. Tales cilindros de tipos conocidos estan fabricados, habitualmente, de laton o en cualquier caso de materiales que no presentan una resistencia mecanica elevada, provocando que los mismos, por tanto, se traspasen por medio de perforacion y/o rotura y/o palanca.At present, locks are known that are adapted to allow the closing and opening of a door or a gate, which essentially comprise an opening cylinder provided with a seat for inserting a suitable key that is adapted to allow the activation of the cylinder and , therefore, unlocking the lock. Such cylinders of known types are usually made of brass or in any case of materials that do not have a high mechanical resistance, causing them, therefore, to be transferred by means of perforation and / or breakage and / or lever.

Con el fin de proteger tales cilindros de tipos conocidos frente a una posible entrada forzada, es habitual fijar un elemento de cubierta especial o base a la cerradura, en una posicion que es tal como para enrollar un extremo del cilindro, siendo tal elemento de cubierta especial o base esencialmente cilmdrico y presentando una abertura frontal que esta parcialmente obstruida por un disco de proteccion rotatorio en el que se define una ranura que esta adaptada para permitir la insercion de la llave.In order to protect such cylinders of known types against a possible forced entry, it is customary to attach a special cover element or base to the lock, in a position that is such as to wind one end of the cylinder, such cover element being special or essentially cylindrical base and having a front opening that is partially obstructed by a rotating protection disc in which a slot is defined which is adapted to allow the insertion of the key.

Por tanto, tal disco de proteccion constituye una defensa para el cilindro frente a una perforacion llevada a cabo con brocas helicoidales, pero al mismo tiempo permite la insercion y rotacion de la llave en el cilindro que se mantiene en la base.Therefore, such a protection disk constitutes a defense for the cylinder against a drill carried out with helicoidal drills, but at the same time allows the insertion and rotation of the key in the cylinder that is maintained in the base.

Sin embargo, tales bases de tipos conocidos presentan una desventaja: estan montadas desde el exterior y se fijan a la cerradura por medio de tornillos que estan integrados en el panel de la puerta, que esta constituido por diversos materiales tales como madera, plastico, laminas de metal, etc.However, such bases of known types present a disadvantage: they are mounted from the outside and are fixed to the lock by means of screws that are integrated in the door panel, which is constituted by various materials such as wood, plastic, sheets of metal, etc.

Normalmente, entre el panel y la base existe un espacio, o “huelgo”, que esta cubierto y ocultado por una placa decorativa que esta fijada al panel.Normally, between the panel and the base there is a space, or "gap", that is covered and hidden by a decorative plate that is fixed to the panel.

Habitualmente, la entrada forzada se hace posible retirando la placa decorativa del panel de la puerta, ya que la placa se fija generalmente a la puerta con dos tornillos que pueden retirarse desde el exterior, y entonces insertar un tubo u otra herramienta bajo el embellecedor de tal manera que, al forzarlo, los dos tornillos de fijacion de la cerradura se arrancan y, al mismo tiempo, el cilindro se rompe, facilitando, por tanto, la apertura de la puerta desde el exterior.Usually, forced entry is made possible by removing the decorative plate from the door panel, since the plate is usually fixed to the door with two screws that can be removed from the outside, and then inserting a tube or other tool under the trim. such that, when forced, the two fastening screws of the lock are started and, at the same time, the cylinder is broken, thus facilitating the opening of the door from the outside.

Una desventaja de las soluciones descritas anteriormente esta constituida, por tanto, por la facilidad de retirar la placa decorativa del panel de la puerta o verja.A disadvantage of the solutions described above is therefore constituted by the ease of removing the decorative plate from the panel of the door or gate.

La solicitud de patente italiana n° TV2007A000195 que fue presentada el 7 de diciembre de 2007, divulga una estructura de un dispositivo de proteccion antientrada forzada y antipalanca, particularmente para una cerradura. Ventajosamente, la estructura comprende una base que es sustancialmente cilmdrica y que esta asociada o que puede asociarse axialmente con el cilindro de la cerradura, y en cuya superficie lateral, comenzando desde el extremo de la base orientado hacia el lado opuesto a la cerradura, se forman unos primero y segundo rebajes anulares.The Italian patent application No. TV2007A000195 that was filed on December 7, 2007, discloses a structure of a forced and anti-lever anti-entrapment protection device, particularly for a lock. Advantageously, the structure comprises a base that is substantially cylindrical and that is associated or that can be associated axially with the cylinder of the lock, and on whose side surface, starting from the end of the base facing the side opposite the lock, is they form first and second annular recesses.

De manera axial a la base, se forma un primer asiento para fijar el cilindro que esta dispuesto de tal manera que el orificio de llave de acceso para una llave adecuada esta en una posicion que esta desviada del eje central longitudinal de la base.Axially to the base, a first seat is formed to secure the cylinder which is arranged in such a way that the access key hole for a suitable key is in a position that is offset from the longitudinal central axis of the base.

En la base se forman orificios, lateralmente con respecto al primer asiento y de manera axial con respecto a la propia base, que estan adaptados para la insercion de tornillos adecuados.In the base, holes are formed, laterally with respect to the first seat and axially with respect to the base itself, which are adapted for the insertion of suitable screws.

Ventajosamente, de manera axial con respecto a la base, se forma un ojal que es preferentemente de planta circular y, en utilizacion, esta orientado hacia el orificio de llave formado en el cilindro de la cerradura.Advantageously, axially with respect to the base, an eyelet is formed which is preferably circular in plan and, in use, is oriented towards the key hole formed in the cylinder of the lock.

De manera conveniente, el ojal presenta dimensiones que son tales como para permitir la insercion y rotacion del vastago de la llave que, de esta manera, puede insertarse en el orificio de llave del cilindro de la cerradura. Ventajosa pero no necesariamente, un disco de proteccion de orificio de llave se inserta de manera rotatoria en el ojal, y de manera diametral a este disco existe una abertura adecuada que presenta una forma y disposicion que son tales como para permitir el paso del vastago de la llave a su traves.Conveniently, the eyelet has dimensions that are such as to allow insertion and rotation of the key stem, which can thus be inserted into the key hole of the lock cylinder. Advantageously but not necessarily, a keyhole protection disk is inserted rotatably in the eyelet, and diametrically to this disk there is a suitable opening having a shape and arrangement that are such as to allow the passage of the stem the key to your crossing.

Tambien existe una placa decorativa que esta provista de un cuerpo cilmdrico en cuya parte inferior sobresalen radialmente dos aletas, que se conforman aproximadamente de manera complementaria a los primero y segundo rebajes anulares en la base.There is also a decorative plate that is provided with a cylindrical body in the bottom of which protrude radially two fins, which conform approximately complementarily to the first and second annular recesses in the base.

La placa decorativa se inserta en la base en la parte trasera, mediante la insercion de las aletas en los primero y segundo rebajes, al tiempo que tornillos especiales cierran la base y la placa decorativa a la cerradura que se dispone, por ejemplo, en la puerta.The decorative plate is inserted into the base at the rear, by inserting the fins into the first and second recesses, while special screws close the base and decorative plate to the lock that is available, for example, in the door.

Las aletas insertadas en los primero y segundo rebajes anulares tienden a impedir la salida de la placa decorativa de su asiento, aunque los tornillos esten sueltos, impidiendo por tanto que la placa se arranque, lo que permite que la base de la cerradura se arranque con herramientas de ladrones.The fins inserted in the first and second annular recesses tend to prevent the decorative plate from leaving its seat, even though the screws are loose, thus preventing the plate from starting, which allows the base of the lock to be started with thieves tools.

La principal desventaja que puede encontrarse en este dispositivo conocido consiste en el hecho de que las aletas, cuando se realiza un intento de forzar una entrada, pueden doblarse facilmente; esto produce un nivel de huelgo con respecto a los primero y segundo rebajes en los que estan insertadas, lo que permite la extraccion de la placa decorativa si se tira de la misma axialmente.The main disadvantage that can be found in this known device consists in the fact that the fins, when an attempt is made to force an entrance, can be easily bent; this produces a level of clearance with respect to the first and second recesses in which they are inserted, which allows the extraction of the decorative plate if it is pulled axially.

El documento US n° 1.579.139 divulga una placa de bloqueo para recibir y mantener frente a rotacion una cerradura cilmdrica. En los documentos DE 426263 C y DE 29503138 U1 se divulgan disposiciones adicionales que impiden una actuacion mediante fuerza de una cerradura de puerta.US Patent No. 1,579,139 discloses a blocking plate for receiving and maintaining a cylinder lock in front of rotation. DE 426263 C and DE 29503138 U1 disclose additional provisions that prevent a force action of a door lock.

El objetivo de la presente invencion es el de resolver los problemas tecnicos mencionados anteriormente, eliminando por tanto las desventajas en la tecnica anterior, proporcionando un dispositivo que impide la extraccion de la placa decorativa de la base.The objective of the present invention is to solve the aforementioned technical problems, thus eliminating the disadvantages in the prior art, by providing a device that prevents the removal of the decorative plate from the base.

Dentro de este objetivo, un objeto de la invencion es proporcionar un dispositivo que puede realizarse con sistemas y maquinaria conocidos.Within this aim, an object of the invention is to provide a device that can be realized with known systems and machinery.

Con referencia a la figura 1, el numero de referencia 1 indica un dispositivo de proteccion que puede aplicarse a una cerradura 2 adecuada para insertarse en una puerta 3.With reference to Figure 1, the reference number 1 indicates a protection device that can be applied to a lock 2 suitable for insertion in a door 3.

Con referencia a la figura 2 y las siguientes, el numero de referencia 4 indica una base, preferentemente pero no de manera exclusiva cilmdrica, que presenta en su superficie frontal 5 por lo menos dos primeros orificios axiales roscados 6, diametralmente opuestos, para alojar dos tornillos prisioneros 7.With reference to Figure 2 and the following, the reference number 4 indicates a base, preferably but not exclusively cylindrical, having on its front surface 5 at least two first threaded axial holes 6, diametrically opposed, to accommodate two captive screws 7.

La base 4 presenta, comenzando en la superficie trasera 8, un primer asiento axial 9 que presenta esencialmente una forma de T, cuya pata 9a no pasa a traves de la base 4 y cuyo cabezal 9b esta conectado a un segundo orificio 10 que esta formado sobre la superficie frontal 5.The base 4 has, starting at the rear surface 8, a first axial seat 9 having essentially a T shape, whose leg 9a does not pass through the base 4 and whose head 9b is connected to a second hole 10 that is formed on the front surface 5.

Un localizador 11 elastico se inserta en el cabezal 9b del primer asiento 9, localizador 11 que presenta forma de C y funciona radialmente para retener axialmente un disco 12 de proteccion de orificio de llave que se inserta de manera rotatoria en una posicion desviada del eje de la base 4.An elastic locator 11 is inserted into the head 9b of the first seat 9, locator 11 having a C-shape and radially operating to axially retain a key hole protection disc 12 which is inserted rotatably in a position offset from the axis of the key. the base 4.

El disco 12 de proteccion de orificio de llave presenta diametralmente una primera ranura 13 para el paso de un vastago 14 de una llave 15 que se insertara en un cilindro 15a que forma la cerradura 2.The key hole protection disk 12 has diametrically a first slot 13 for the passage of a rod 14 of a key 15 that is inserted in a cylinder 15a forming the lock 2.

La base 4 presenta, en su superficie exterior lateral 4a y comenzando en la superficie trasera 8, por lo menos dos asientos axiales; en la forma de realizacion particular mostrada, se tienen en consideracion cuatro asientos axiales 16a, 16b, 16c, 16d, que presentan una longitud mas corta que la de la base 4.The base 4 has, on its lateral outer surface 4a and starting at the rear surface 8, at least two axial seats; in the particular embodiment shown, four axial seats 16a, 16b, 16c, 16d are considered, which have a shorter length than that of the base 4.

El eje de los primeros dos orificios roscados 6 que alojan los dos tornillos prisioneros 7 coincide con el eje de los cuatro asientos axiales 16a, 16b, 16c, 16d que se disponen diametralmente entre sfThe axis of the first two threaded holes 6 which house the two grub screws 7 coincides with the axis of the four axial seats 16a, 16b, 16c, 16d which are arranged diametrically to each other

Cada uno de los cuatro asientos axiales 16a, 16b, 16c, 16d presenta, en una seccion transversal, y, por tanto, en una vista en planta, un perfil con una forma irregular; una forma semicircular esta excluida de manera explfcita de las posibles formas.Each of the four axial seats 16a, 16b, 16c, 16d has, in a cross section, and, therefore, in a plan view, a profile with an irregular shape; a semicircular shape is explicitly excluded from the possible forms.

De esta manera, para cada uno de los cuatro asientos, se define un primer borde perimetral 17 que presenta una posicion no lineal en el sentido de que sigue una trayectoria que, en su posicion, produce por lo menos un cambio de direccion.In this way, for each of the four seats, a first perimeter edge 17 is defined which has a non-linear position in the sense that it follows a trajectory which, in its position, produces at least one change of direction.

La forma del primer borde perimetral 17 puede, por tanto, oscilar y variar de manera extensa, ya que es suficiente con que presente un perfil con por lo menos un cambio de direccion en su posicion.The shape of the first perimetric edge 17 can therefore oscillate and vary extensively, since it is sufficient for it to present a profile with at least one change of direction in its position.

El primer borde perimetral 17 presenta, en la forma de realizacion particular mostrada, una posicion simetrica que define un primer arco central 17a que esta conectado a dos segundos arcos laterales 17b conectados, en un extremo, a la superficie lateral 4a.The first perimeter edge 17 has, in the particular embodiment shown, a symmetrical position defining a first central arc 17a that is connected to two second lateral arcs 17b connected, at one end, to the lateral surface 4a.

Naturalmente, tal posicion tambien puede ser asimetrica; ademas, la forma del borde perimetral puede ser la que mas cumpla los requisitos espedficos.Naturally, such a position can also be asymmetrical; In addition, the shape of the perimeter edge may be the one that most meets the specific requirements.

El radio de curvatura de los primero y segundo arcos 17a, 17b debe ser diferente para lograr un cambio en la direccion en la region de conexion entre los mismos.The radius of curvature of the first and second arcs 17a, 17b must be different to achieve a change in direction in the region of connection between them.

La base 4 presenta, en su superficie trasera 8, en una region que esta desviada de los cuatro asientos axiales 16a, 16b, 16c, 16d, dos terceros orificios ciegos axiales 18, que estan roscados en su interior y dispuestos diametralmente entre sf; los terceros orificios 18 alojan dos tornillos 19 para fijar la base 4 a la puerta 3.The base 4 has, on its rear surface 8, in a region that is offset from the four axial seats 16a, 16b, 16c, 16d, two third axial blind holes 18, which are threaded therein and arranged diametrically to each other; the third holes 18 house two screws 19 for fixing the base 4 to the door 3.

En la superficie lateral 4a de la base 4 tambien se encuentra, en una region no afectada por los cuatro asientos axiales 16a, 16b, 16c, 16d, un asiento anular 20, para alojar una junta 21 del tipo junta torica, y un anillo 22 de limitacion, en relieve, contra el que descansa una cubierta 23 de proteccion haciendo tope que cubre la superficie frontal 5 de la base 4.On the lateral surface 4a of the base 4 there is also, in a region not affected by the four axial seats 16a, 16b, 16c, 16d, an annular seat 20, for receiving a gasket 21 of the toric joint type, and a ring 22 of relief, in relief, against which rests a protective cover 23 with a stop covering the front surface 5 of the base 4.

La cubierta 23 de proteccion, que presenta una forma que es complementaria a la base 4 y hueca, presenta un cuarto orificio 24, que es axial y esta desviado, para que la primera ranura 13 sea accesible desde el exterior. Una placa 25 decorativa, realizada preferentemente a partir de una placa de metal prensada, presenta un cuerpo 26 hueco que esta conformado de manera complementaria a la superficie lateral exterior de la base 4 y, por tanto, en la forma de realizacion particular mostrada, es cilmdrico con un diametro interior aproximadamente igual al diametro exterior de la base 4; tambien existe un armazon 27 frontal y un quinto orificio o abertura trasera 28. El quinto orificio o abertura 28 se conforma de manera complementaria a la superficie lateral exterior de la base 4; en la forma de realizacion mostrada, el diametro del quinto orificio 28 es tal como para permitir el paso de la base 4.The protective cover 23, which has a shape that is complementary to the base 4 and hollow, has a fourth hole 24, which is axial and is offset, so that the first slot 13 is accessible from the outside. A decorative plate 25, preferably made from a pressed metal plate, has a hollow body 26 that is shaped in a complementary manner to the outer lateral surface of the base 4 and, therefore, in the particular embodiment shown, is Cylindrical with an inner diameter approximately equal to the outer diameter of the base 4; there is also a front frame 27 and a fifth hole or rear opening 28. The fifth hole or opening 28 is shaped in a complementary manner to the outer side surface of the base 4; in the embodiment shown, the diameter of the fifth hole 28 is such as to allow the passage of the base 4.

En el cuerpo 26 hueco existe ademas un borde perimetral trasero 26a, que sobresale en la direccion de la base 4 y a partir del cual sobresalen cuatro aletas 29a, 29b, 29c, 29d, radialmente y hacia el interior del quinto orificio o abertura 28, que se conforman de manera complementaria a los cuatro asientos axiales 16a, 16b, 16c, 16d formados en la base 4.In the hollow body 26 there is also a rear perimeter edge 26a, which protrudes in the direction of the base 4 and from which four fins 29a, 29b, 29c, 29d protrude, radially and into the interior of the fifth orifice 28, which they conform in a complementary manner to the four axial seats 16a, 16b, 16c, 16d formed in the base 4.

Cada una de las aletas 29a, 29b, 29c, 29d define, en una seccion transversal, un segundo borde perimetral 30 que presenta una geometna equivalente a la de los cuatro asientos axiales 16a, 16b, 16c, 16d. Por tanto, en la forma de realizacion espedfica mostrada, se define un segundo arco central 30a que esta flanqueado por dos segundos arcos laterales 30b conectados en un extremo a terceros arcos de descarga 30c que a su vez estan conectados al borde perimetral trasero 26a del cuerpo 26 hueco.Each of the fins 29a, 29b, 29c, 29d defines, in a cross section, a second perimeter edge 30 having a geometry equivalent to that of the four axial seats 16a, 16b, 16c, 16d. Therefore, in the specific embodiment shown, a second central arc 30a is defined which is flanked by two second lateral arches 30b connected at one end to third discharge arcs 30c which in turn are connected to the rear perimeter edge 26a of the hollow body 26.

El funcionamiento del dispositivo segun la invencion es de la siguiente manera.The operation of the device according to the invention is as follows.

La placa 25 decorativa se inserta en el orificio de alojamiento 10, que esta presente en la puerta 3, desde el exterior, de manera que el armazon 27 esta colocado en el exterior de la puerta 3.The decorative plate 25 is inserted into the receiving hole 10, which is present in the door 3, from the outside, so that the frame 27 is placed outside the door 3.

Posteriormente, la base 4 se inserta, yendo en primer lugar la superficie trasera 8, en el cuerpo 26 hueco de modo que las aletas 29a, 29b, 29c, 29d de la placa 25 decorativa pueden deslizarse axialmente al interior de los asientos axiales 16a, 16b, 16c, 16d correspondientes que estan ubicados en la base 4.Subsequently, the base 4 is inserted, with the rear surface 8 first, into the hollow body 26 so that the fins 29a, 29b, 29c, 29d of the decorative plate 25 can slide axially into the axial seats 16a, 16b, 16c, 16d corresponding that are located in base 4.

La disposicion de los cuatro asientos axiales 16a, 16b, 16c, 16d y de las aletas 29a, 29b, 29c, 29d correspondientes puede variar a voluntad, en el sentido de que puede haber, por ejemplo, dos en un mismo eje diametral, y dos en ejes diferentes.The arrangement of the four axial seats 16a, 16b, 16c, 16d and the corresponding fins 29a, 29b, 29c, 29d may vary at will, in the sense that there may be, for example, two on the same diametral axis, and two on different axes.

El numero de estas aletas y asientos tambien puede variar, siendo suficiente con que haya por lo menos dos. Por medio de los tornillos 19, la base 4 se fija a la puerta 3 junto con la cerradura 2 y posteriormente se ajusta de manera ventajosa la posicion de la placa 25 decorativa, por medio de los tornillos prisioneros 7, de modo que hace tope contra la superficie exterior de la puerta 3. Esta operacion puede llevarse a cabo en una amplia variedad de grosores de puertas o verjas.The number of these fins and seats may also vary, being sufficient that there are at least two. By means of the screws 19, the base 4 is fixed to the door 3 together with the lock 2 and subsequently the position of the decorative plate 25 is advantageously adjusted, by means of the captive screws 7, so that it stops against the exterior surface of the door 3. This operation can be carried out in a wide variety of thicknesses of doors or gates.

En este punto, la cubierta 23 de proteccion se aplica, desde el exterior, en la base 4, para cubrir el acceso a los tornillos prisioneros 7 y alineando el segundo orificio 10 con la primera ranura 13 con el objetivo de permitir que la llave 15 se utilice.At this point, the protective cover 23 is applied, from the outside, on the base 4, to cover the access to the captive screws 7 and aligning the second hole 10 with the first slot 13 in order to allow the key 15 be used.

La forma de las aletas 29a, 29b, 29c, 29d y la forma de los asientos axiales 16a, 16b, 16c, 16d determina regiones recortadas entre los segundos arcos laterales 30b y los arcos que constituyen el primer borde perimetral 17 y el segundo borde perimetral 30; estas regiones, en parte gracias a la presencia del borde perimetral trasero 26a que confiere robustez a las aletas 29a, 29b, 29c, 29d, no permiten que estas aletas se deslicen fuera de los asientos axiales 16a, 16b, 16c, 16d, tambien como resultado de deformaciones que se imprimen sobre la placa 25 decorativa, diferentes de las del procedimiento en la tecnica conocida.The shape of the fins 29a, 29b, 29c, 29d and the shape of the axial seats 16a, 16b, 16c, 16d determine regions cut between the second side arches 30b and the arcs constituting the first perimeter edge 17 and the second edge perimeter 30; these regions, in part thanks to the presence of the rear perimetral edge 26a which confers robustness to the fins 29a, 29b, 29c, 29d, do not allow these fins to slide out of the axial seats 16a, 16b, 16c, 16d, also as result of deformations that are printed on the decorative plate 25, different from those of the process in the known art.

De esta manera, se impide que se determine un nivel de huelgo entre los asientos axiales 16a, 16b, 16c, 16d y las aletas 29a, 29b, 29c, 29d, porque la deformacion de incluso uno de los primeros, segundos y terceros arcos 17a, 17b, 30a, 30b, 30c conllevana engancharse con los asientos axiales 16a, 16b, 16c, 16d.In this way, a level of clearance between the axial seats 16a, 16b, 16c, 16d and the fins 29a, 29b, 29c, 29d is prevented from being determined, because the deformation of even one of the first, second and third arches 17a 17b, 30a, 30b, 30c entails hooking with the axial seats 16a, 16b, 16c, 16d.
