State of the art

Actualmente son ampliamente conocidas las cerraduras de seguridad,del tipo conocido como cerraduras de arpón, que comprenden: un cuerpo de acero en el que se encuentra alojado un cilindro giratorio accionable por el extremo anterior del cuerpo de la cerradura mediante la llave correspondiente, y un cerrojo o arpónasociado al cilindro y que gira conjuntamente con dicho cilindro. Currently, security locks, of the type known as harpoon locks, are widely known, comprising: a steel body in which a rotating cylinder is housed operable by the front end of the lock body by means of the corresponding key, and a bolt or harpoon associated with the cylinder and which rotates together with said cylinder.

Este tipo de cerraduras utilizadas ampliamente en puertas de persiana, yen dispositivos de seguridad para persianas tal como el descrito en el modelo de utilidad 201430236 del mismo solicitante, presentan el inconveniente de que el This type of locks widely used in blind doors, and in safety devices for blinds such as the one described in the utility model 201430236 of the same applicant, have the disadvantage that the

cilindro, para facilitar su mecanización está constituido en latón, pudiendo ser taladrado desde el extremo anterior de la cerradura para liberar el mecanismo interno de bloqueo y conseguir la apertura fraudulenta de la cerradura. Cylinder, to facilitate its mechanization, is made of brass, and can be drilled from the front end of the lock to release the internal locking mechanism and achieve fraudulent opening of the lock.

El solicitante de la presente invención desconoce la existencia en el mercado de antecedentes de cerraduras de seguridad para persianas metálicas que dispongan de medios adecuados para impedir la violación de la cerradura mediante el taladrado del cilindro. The applicant of the present invention is unaware of the existence in the market of antecedents of security locks for metal shutters that have adequate means to prevent the violation of the lock by drilling the cylinder.

Description of the invention

La cerradura de seguridad reforzada objeto de la presente invención, siendo de mencionado tipo de cerraduras de arpón, presenta unas particularidades constructivas orientadas a resolver el problema técnico que se plantea y concretamente a impedir que el cilindro cerradura pueda ser taladrado para conseguir el desbloqueo de la cerradura. The reinforced security lock object of the present invention, being of said type of harpoon locks, presents constructive particularities oriented to solve the technical problem that arises and specifically to prevent the lock cylinder from being drilled to achieve the unlocking of the lock.

Para ello y de acuerdo con la invención esta cerradura comprende en el extremoanterior del cuerpo unaconfiguración anular provista de un pasaje de acceso de la llave de la cerradura hacia el interior del cilindro y de una cavidad posterior en el que se encuentra alojado con posibilidad de giro libre un disco antitaladro, de acero reforzado, que cubre el extremo anterior del cilindro de la cerradura y que presenta una ranura de paso de la llave hacia el interior del mencionado cilindro. For this purpose and according to the invention, this lock comprises at the front end of the body an annular configuration provided with an access passage of the key of the lock towards the inside of the cylinder and of a rear cavity in which it is housed with the possibility of turning free of an anti-drill disc, made of reinforced steel, which covers the front end of the cylinder of the lock and which has a slot for the passage of the key into the said cylinder.

La posibilidad de giro libre de dicho disco antitaladro respecto al cuerpo y al cilindro de la cerradura impide que el disco sea taladrado con una broca y consiguientemente que dicha broca pueda alcanzar al cilindro. The possibility of free rotation of said anti-drill disk with respect to the body and the cylinder of the lock prevents the disk from being drilled with a drill and consequently that said drill can reach the cylinder.

Cabe mencionar que la mencionada configuración anular puede encontrarse definida en el propio cuerpo de la cerradura, o estar definida en una pieza independiente fijada al cuerpo de la cerradura de forma permanente, por ejemplo mediante soldadura. It should be mentioned that said annular configuration can be defined in the lock body itself, or be defined in a separate part fixed to the lock body permanently, for example by welding.

Description of the figures.

Para complementar la descripción que se está realizando y con objeto de facilitar la comprensión de las características de la invención, se acompaña a la presente memoria descriptiva un juego de dibujos en los que, con carácter ilustrativo y no limitativo, se ha representado lo siguiente: To complement the description that is being made and in order to facilitate the understanding of the characteristics of the invention, a set of drawings is attached to the present specification in which, for illustrative and non-limiting purposes, the following has been represented:
