    [0002] Locking cylinder with regatta key
    [0004] Field of the invention
    [0005] This invention concerns a locking cylinder with key consisting of a fixed locking body with a rotating cylinder inserted rotatably in said fixed locking body and with a key insertion slot, combining, to give greater security, several locking mechanisms. locking, with active pins corresponding to the milled notch of the key, race readers, floating pins that act passively, and unlocking by means of a ferromagnetic insert. Providing the lock cylinder assembly with a key, greater security, preventing it from being manipulated for opening without the corresponding key.
    [0007] Prior state of the art
    [0008] At present, and as a reference to the state of the art, it is known to use closing cylinders that use active pins that are placed in the rotating cylinder in a sliding manner, which together with the counter pins and pushed by springs, block the rotation. In this way, with the insertion of a properly milled key, the pins are moved and aligned, allowing the cylinder to rotate.
    [0009] However, this mechanism does not prevent the opening technique by the printing method, by means of which aluminum sheets are placed in a special key that when inserted together in the closing cylinder, these sheets are deformed leaving the traces of the combination of pins mounted on the closing cylinder, thus achieving the opening. For this reason, the use of rotating cylinders that combine the previous mechanism with the use of a regatta printed on the flat part of the blade of the key is known, which is read by some pins that move in correspondence with the regatta of the key. to align and allow cylinder rotation when active pins are also aligned.
    [0010] The present invention seeks to provide an improved lock cylinder and key that employ the combination of these two methods, together with additional rotary cylinder locking mechanisms and thus increase the possibilities of variation in the key and ensure greater interlocking security. , preventing that even if a hypothetical thief managed to get hold of the combination of the key cuts, he could unlock the rotating cylinder, because he would also have to overcome the additional locking mechanisms.
    [0011] Explanation of the invention and advantages
    [0012] Against this state of the art, the present invention refers to a locking cylinder with key comprising a fixed locking body with a rotating cylinder inserted rotatably in said fixed locking body and with a key insertion slot; with a plurality of spring-loaded active pins and counter-pins mounted radially on the rotary cylinder with their axial axes in the vertical direction, with a combination of active pins corresponding to the combination of the key's milled notch; being the reversible key with symmetrical blade faces and in its longitudinal direction with a race read by a plurality of race pins by means of race readers, and said race pins are mounted transversely on the rotating cylinder, with their axes axially perpendicular to the direction of the active pins; in which there is a plurality of floating pins that can be unlocked by lateral notches of the racing pins, said floating pins acting in the same direction as the active pins.
    [0014] This key lock cylinder configuration allows a triple lock that prevents tampering more effectively and safely than other locks. Thus, the unwanted opening of the closing cylinder by the fraudulent techniques currently used is avoided.
    [0015] Thanks to the configuration of active double-diameter pins, it is possible to make them hang on the rotor, preventing them from going down to the bottom in the absence of a key, but at the same time part of the counter-pin is inserted into the rotor. This allows a bumping wrench to not be able to transmit enough movement to remove the counterpyon from the rotor, protecting the cylinder against the bumping method of opening. On the other hand, with the design of the shape that some pins have as counterpits, it is possible to give the function of anti-pick as anti-printing to the cylinder.
    [0016] In addition to the above, to increase the possibilities of variation in the key and to guarantee greater security, the key is provided with a groove-shaped regatta that extends longitudinally in the blade of the key. With this regatta, it is achieved that regatta pins mounted transversely on the rotating cylinder and which are driven towards the fixed closing body by springs, move laterally towards the interior of the rotating cylinder. This lateral displacement is achieved thanks to race readers, which can be constituted by, for example, a stud or carving, an insert or a key, located at the bottom of the race pins that read the race and move the race pins so that are aligned, leaving the fixed body and thus unlocking the rotating cylinder. Thus, this configuration prevents the closing cylinder from opening by the printing method.
    [0017] Additionally, to give the closing cylinder greater security, in the rotating cylinder there are floating pins mounted radially in a vertical direction, and which are vertically driven towards the fixed closing body by springs to achieve the locking of the rotating cylinder. For unlocking these floating pins, the racing pins are equipped in their upper part with lateral notches that, once the racing pins are aligned coming out of the fixed body, allow the floating pins to move towards the axis of the cylinder. rotary. Thus, an additional security mechanism is achieved both against the pick technique and the printing technique, achieving an additional lock that cannot be released without the appropriate key. Furthermore, thanks to the use of the usual pins in the fixed closing body and in the rotating cylinder and of a steel ball also in the rotating cylinder, an anti-drill security is achieved, the closing cylinder of the present invention being anti-bumping. Anti-pick, anti-print and anti-drill.
    [0019] In order for the locking to be produced by the floating pins, they have a head with a curved configuration in correspondence with the curved configuration of the upper part of the racing pins, and that with the help of springs keep the floating pins in the body fixed closure. Thus, thanks to this configuration a safe movement without jamming is achieved, and by placing the heads of the floating pins in the lateral notches of the racing pins, a smooth unlocking is achieved.
    [0021] Another characteristic of the invention is that it is envisaged that there is at least one race pin that has a race reader made up of a ferromagnetic insert capable of confronting a ferromagnetic insert of the key. Thanks to this configuration, the regatta pin, instead of acting by means of a pin, is laterally displaced by the action of a ferromagnetic insert located in the lower part of the race pin, which in the limit position of penetration of the key produces the displacement of the racing pin until the ferromagnetic insert of the latter is facing the ferromagnetic insert of the key. Thus, the race pin comes out of the fixed closing body and lines up with the other race pins to allow the floating pins to move thanks to the lateral notch. An additional safety mechanism is thus achieved compared to the printing technique, providing greater safety to the closing cylinder. As well as a personalization of the security system and a greater number of combinations for the locking cylinder.
    [0022] It is envisaged that the floating pins are of different heights corresponding to cavities in the key. Thanks to this configuration, although the racing pins are aligned, unlocking the rotating cylinder and allowing the floating pins to move, in the event that the floating pins are longer, they will continue to block the rotating cylinder when their head is placed inside the body. fixed closure. In order for them to move until their head sits in the lateral notches of the racing pins, it is foreseen to make cavities in the key in correspondence with said floating pins, allowing these to move downwards and unlock the cylinder. Thus, a triple lock is achieved providing additional security by increasing the possibilities of variation in the key.
    [0024] Finally, it is envisaged that in the key there is at least one fin that protrudes from the thickness of the blade in correspondence with at least one of the active pins. This configuration allows the corresponding active pin to be unlocked only if it corresponds to the height of the fin, further increasing the possibilities of variation in the key and more effectively guaranteeing the anti-impression properties of the locking cylinder.

    [0079] Presentation of a preferred embodiment
    [0080] In relation to the drawings and references listed above, a preferred arrangement of the object of the invention is illustrated in the attached drawings, referring to a locking cylinder (1) with key (2) comprising a fixed locking body (3) with a rotary cylinder (4) rotatably inserted in said fixed closing body (3) and with a slot (5) for inserting the key (2); with a plurality of active pins (6) and counter-pins (7) spring loaded and radially mounted on the rotary cylinder (4) with their axial axes in the vertical direction with a combination of active pins (6) corresponding to the milled notch combination (17) of the key (2); the key (2) being reversible with faces of the blade (19) symmetrical and in its longitudinal direction with a race (8) read by a plurality of race pins (9) by means of race readers (10), and said regatta pins (9) being mounted transversely in the rotary cylinder (4) with their axial axes substantially perpendicular to the direction of the active pins (6); in which there is a plurality of floating pins (12) capable of being unlocked by some lateral notches (11) of the racing pins (9), said floating pins (12) acting in the same direction as the active pins (6) .
    [0081] As can be seen in figure 1, the active pins (6) and counter-pins (7) are located in the lower part of the fixed closing body (3) and the rotary cylinder (4), mounted radially sliding in the vertical direction, and that remain inside the fixed closing body (3) by the action of some springs, producing a first blockage of the rotating cylinder (4) that avoids the bumping opening technique. Thus, with the configuration of the milled notches (17) of the key (2), as can be seen on the left side of the double cylinder locking cylinder (1) of figure 11, the active pins (6) are aligned and counterpits (7) to allow the rotation of the rotary cylinder (4).
    [0082] However, even if this lock is released, it is also necessary to unblock the racing pins (9) which are mounted transversely sliding in a direction roughly perpendicular to the direction of the active pins (6). Thus, these racing pins (9) are locked inside the fixed closing body (3) by the action of some springs (figure 2). A second blockage is then produced which prevents the impression opening technique. To achieve the unlocking of the race pins (9), it is necessary that the race readers (10) are aligned and come out of their housing in the fixed closing body (3). This lateral displacement is achieved by the movement produced by the regatta (8) in its interaction with the regatta readers (10), which by means of a pin (figure 6), according to the regatta combination (8) drawn, achieve the alignment of the race pins (9) to unlock the rotation of the rotary cylinder (4), as can be seen in figure 3.
    [0084] In addition to the aforementioned locks, there are floating pins (12) that are mounted radially on the rotating cylinder (12) in the same direction as the active pins (6), and that are kept inside the fixed closure body. (3) remaining on the racing pins (9) and producing an additional blockage (figure 4 and figure 11 left part), in a preferred embodiment these floating pins (12) have a head (20) with a curved configuration in correspondence with the curved configuration of the upper part of the racing pins (8), settling on them and causing the blockage. For the displacement of these floating pins (12) and the consequent unlocking, it is necessary that once the racing pins (9) are aligned, some lateral notches (11) made in the upper part of these are also aligned, in this way the head (20) of the floating pin (12) would fit between the lateral notches (11) achieving the displacement of the floating pins (12) towards the axis of the rotating cylinder (4) and consequently unlocking it (figure 5 and figure 11 left part) . Thus, this additional lock provides greater security to the locking cylinder against picking, bumping and printing practices.
    [0086] As can be seen in figure 7, in order to provide greater possibilities of combination of the key (2), it is foreseen that in some embodiments for greater security there will be at least one regatta python (9) with a regatta reader (10) constituted by a ferromagnetic insert (13) capable of facing a ferromagnetic insert (14) of the key (2). Thus, at first the race reader (9) would remain inside the housing of the fixed closure body (3) (figure 9), and at the limit moment of penetration of the key (2), by actuation of the ferromagnetic insert ( 14) of the key (2), causes the lateral displacement of the regatta (9), said ferromagnetic insert (14) of the key (2) facing the ferromagnetic insert (13) of the regatta pin (9). The unlocking of the rotary cylinder (4) is thus achieved (figure 10).
    [0088] In figure 11, in the rotary cylinder (4) on the left it can be seen how it has been unlocked when the key (2) is inserted with the correct combination. However, it is provided that the floating pins (12) are of different heights in correspondence with cavities (15) of the key (2). Thus, in figure 12 it can be seen how one of the taller floating pins (12) has not moved as it does not coincide with a cavity (15) of the key (2), leaving its head (20) inside the fixed closing body (3) and blocking the rotary cylinder (4). For unlocking to take place, it is necessary that the key (2), in addition to the correct regatta configuration (8), contains the correct cavities (15). Thus, the closing cylinder (1) is given more security, achieving a triple lock.
    [0090] Additionally, to reinforce the anti-printing properties of the closing cylinder (1), it is provided that in some embodiments in the key (2) there is at least one fin (16) that protrudes from the thickness of the blade (19) in correspondence with At least one of the active pins (6), said fin (16) will be located in the lower part of the key (2), with another in the upper part as the key (2) is symmetric. In this way, it is difficult to enter a key or silver paper to carry out the printing method. As can be seen in figure 13, this additional lock is released by means of an active pin (6) of lower height in correspondence with the flap (16) (figure 14).
    [0092] Finally, to provide the locking cylinder (1) with anti-drill properties, the use of pins is provided both in the fixed closure body (3) and in the rotating cylinder (4), in addition to a steel ball in the latter, that provides the closing cylinder (1) with greater resistance against the technique of forcing the closing cylinder with a drill.
    [0094] Variations in materials, shape, size and arrangement of the component elements, described in a non-limiting manner, do not alter the essentiality of this invention, this being sufficient to proceed to its reproduction by an expert.
