CILINDROS DE CERRADURA" CAMPO DE LA INVENCiÓN LOCK CYLINDERS " FIELD OF THE INVENTION

Esta invención concierne a un guardapolvos para canales de This invention concerns a dust cover for

5 llave en cilindros de cerradura, de los empleados en cerraduras que se encuentran en ambientes expuestos al polvo, y de los que emplean compuertas para sellar e impedir la entrada de dichas partículas de polvo o de suciedad por el canal de llave del cilindro de cerradura, las cuales son susceptibles de causar el 5 key in lock cylinders, those used in locks that are in environments exposed to dust, and those that use gates to seal and prevent the entry of said dust or dirt particles through the key channel of the lock cylinder , which are likely to cause

10 malfuncionamiento de la cerradura. ESTADO DE LA TÉCNICA ANTERIOR 10 malfunction of the lock. STATE OF THE PREVIOUS TECHNIQUE

En la actualidad y como referencia al estado de la técnica, es habitual y conocido el empleo de distintos dispositivos guardapolvos dispuestos en cerraduras empleadas en ambientes At present and as a reference to the state of the art, it is usual and known the use of different dust protection devices arranged in locks used in environments

15 con alta creación de partículas de suciedad , como pueden ser talleres de carpintería, talleres de mecanizado, etc., en los cuales se generan grandes cantidades de polvo o virutas de pequeño tamaño susceptibles de introducirse por el canal de llave y depositarse en el interior del cilindro de cerradura, causando el 15 with high creation of dirt particles, such as carpentry workshops, machining workshops, etc., in which large amounts of dust or small chips are generated that can be introduced through the key channel and deposited inside of the lock cylinder, causing the

20 bloqueo de la misma o su malfuncionamiento. Una solución habitual empleada en el gremio de la cerrajería para el problema planteado, se basa en la colocación de una pequeña placa giratoria situada en el frente del cilindro de cerradura, la cual oculta el canal de llave cuando se coloca sobre 20 blocking it or its malfunction. A common solution used in the locksmith's guild for the problem, is based on the placement of a small turntable located in the front of the lock cylinder, which hides the key channel when placed on

25 él. Esta solución implica que el usuario es el responsable de evitar la entrada de suciedad en el canal de llave, teniendo que colocar manualmente dicha placa en la posición correspondiente que oculta el canal de llave. Es por tanto muy probable que en numerosas ocasiones, debido a olvidos o descuidos de los 25 him. This solution implies that the user is responsible for preventing dirt from entering the key channel, having to manually place said plate in the corresponding position that conceals the key channel. It is therefore very likely that on numerous occasions, due to forgetfulness or neglect of

30 usuarios, el canal de llave de la cerradura quede expuesto al exterior, permitiendo la entrada de elementos indeseables. Otro tipo de solución , es el uso de dispositivos que contienen compuertas asociadas a muelles o resortes, las cuales se desplazan en dirección transversal durante la introducción de la 30 users, the key channel of the lock is exposed to the outside, allowing the entry of undesirable elements. Another type of solution is the use of devices containing gates associated with springs or springs, which move in a transverse direction during the introduction of the

interior del rotor, y llevan asociadas unos muelles elásticos, lo cuales mantienen dichas compuertas en contacto permanente, cerrando el paso a la suciedad que puede introducirse por el canal de llave, y permiten que dichas compuertas se desplacen al 5 toparse con la punta de la llave, pudiendo dicha llave seguir introduciéndose en el cilindro de cerradura para alcanzar los pitones de la misma. El problema del empleo de este tipo de solución radica en la perdida de propiedades elásticas y deformaciones permanentes que sufren los muelles, debidas 10 principalmente a la fatiga acumulada durante su uso y a la acumulación de partículas solidas (polvo, virutas, etc.), causando un malfuncionamiento del dispositivo con el paso del tiempo. Además, una fuerza excesiva en estos muelles para ocasionar el cierre, puede generar que las compuertas rocen la pala de la llave inside the rotor, and have associated elastic springs, which keep said gates in permanent contact, closing the passage to the dirt that can be introduced through the key channel, and allow said gates to move when they meet the tip of the key, said key being able to continue entering the lock cylinder to reach the pythons thereof. The problem of using this type of solution lies in the loss of elastic properties and permanent deformations suffered by the springs, mainly due to the accumulated fatigue during use and the accumulation of solid particles (dust, chips, etc.), causing a malfunction of the device over time. In addition, excessive force on these springs to cause closure can cause the dampers to touch the key blade.

15 al introducirla en el canal de llave, generando pequeñas virutas metálicas que pueden alojarse en la cerradura, y ocasionando el problema que se pretende evitar con las compuertas. 15 when introduced into the key channel, generating small metal chips that can be housed in the lock, and causing the problem to be avoided with the floodgates.
