    "DUST GUARD FOR KEY CHANNELS LOCK CYLINDERS "FIELD OF THE INVENTION
    This invention concerns a dust cover for
    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 malfunction of the lock. STATE OF THE PREVIOUS TECHNIQUE
    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 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 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 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 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
    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 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. EXPLANATION OF THE INVENTION AND ADVANTAGES
    Faced with this state of affairs the present invention makes
    20 reference to a dust cover for key channels in lock cylinders, of those used in locks that are in environments exposed to dust particles, the dust covers have a permanent magnet associated to each of them, said doors being housed in a groove
    25 which incorporates the rotor, transverse groove to the main axis of the lock cylinder in which the dust dampers facing each other and with their contact line centered in the key channel are housed. Thanks to this configuration, the dust cover for channels
    30 uses the magnetism of the permanent magnets that are associated with the respective dust dampers to keep the passage of dirt through the key channel closed. The attraction of the magnets keeps the dust gates in the closed position, placing the contact line between both gates of the corresponding key, when the tip of said key is met with the dust gates, these move transversely to the main axis of the lock, allowing to introduce the key in the rotor of the lock cylinder. When removing the
    5 key, the attraction of the magnets causes the gates to return to the closed position of the key channel, preventing the possible entry of dirt into said channel.
    Another feature of the invention is that the peripheral configuration of the permanent magnet is intended to be compatible.
    10 with the insertion of part of its volume into a cavity provided in the dust damper, the remaining permanent magnet volume being housed in a guide channel provided in the transverse groove.
    Thanks to this configuration, the permanent magnet is linked
    15 with the dust damper and the directions of travel that said penstocks can have is limited, since the guide channel that incorporates the rotor houses the remaining permanent magnet volume that is not in the cavity arranged in the dust damper, of way that said magnet
    20 permanent can only move through said channel, and also forcing the dust guard to move only in the transverse direction to the main axis of the lock cylinder, inside the transverse groove. Another feature of the invention is that the gates
    25 dust covers have on their exterior front a separation bezel compatible with the tip of the key that facilitates the opening of said dust gates during the maneuver of introducing said key through the key channel of the lock cylinder.
    30 Thanks to this configuration, during the maneuver of introducing the key into the lock cylinder, the opening movement of the dust dampers in the transverse direction to the main axis of the lock cylinder is facilitated, since the key tip is compatible with this separation bezel, providing a vertical force component that generates this displacement.

    In relation to the drawings and references listed above, a preferred embodiment 10 of the object of the invention is illustrated in the attached drawings, referring to a dust cover for key channels in lock cylinders, in which the dust covers (1) they are associated with each of them a permanent magnet (2), said gates being housed in a transverse groove (6) that incorporates the rotor (5), transverse groove
    15 (6) to the main axis (3a) of the lock cylinder (3) in which the dust dampers (1) facing each other and with their contact line (1b) centered in the key channel (8) are housed.
    Figure 1 shows a preferred embodiment of the lock cylinder (3) that incorporates the 20 dust dampers (1) associated with permanent magnets (2), in which the transverse groove (6) is located close to the front of the rotor (5), thus protecting almost entirely the key channel (8) from the entry of dirt. Said dust covers (1) have built-in cavities (1a) because of their
    25 back as seen in Figure 3b, in which the permanent magnets (2) are housed. The operation of the invention is based on the attractive force of the permanent magnets (2). As can be seen in figures 1 and 2, the dust dampers (1) are housed in the
    30 transverse groove (6), and on the back, housed in the cavity (1), partially incorporate these permanent magnets (2). The remaining volume of said permanent magnets (2) is comprised within the guide channel (7) carved in the transverse groove (6) of the rotor (5), so that said consequence channel, that of the dust dampers ( 2). The attractive force of the permanent magnets (2) places the adjacent dust covers (1), with their contact line (1b) centered on the key channel (8). Therefore, the device is
    5 keep the lock cylinder (3) at rest in the position described, with the dust dampers (1) preventing dirt from entering, until it is operated by means of the key (10).
    In figures 4a, 4b and 4c, the movement performed by the dust dampers (1) is observed when a key 10 (10) is inserted into the lock cylinder (3). Once the tip of the key
    (10) runs into the separation bezel (1c) located on the outer front of the dust dampers (1), the force exerted on the introduction causes said dust dampers (1) to be separated by their contact line (1b) , moving in the transverse direction to the main axis (3a). If the introduction of the key (10) is continued, the dust dampers (1) reach the limit displacement in the transverse groove (6), allowing the complete entry of the key blade (10), allowing it to reach the pitons of key (9). When removing the key
    20 (10) of the key channel (8), the attraction of permanent magnets
    (2) causes the dust shields (1) to move back to the initial position, prior to the introduction of the key (10), so that the key channel (8) is permanently closed, preventing entry of dirt
    25 in the lock cylinder (3). It should be noted that this invention is applicable to both lock cylinders (3) using flat blade keys (10) and edge coding. Do not alter the essentiality of this invention variations in
    30 materials, shape, size and arrangement of the component elements, described in a non-limiting manner, this being sufficient to be reproduced by an expert.
