DESCRIPTION

Locking cylinder with race key

field of invention

This invention relates to a key lock cylinder consisting of a fixed lock body with a rotating cylinder inserted rotating in said fixed lock body and with a key introduction slot, combining, to provide greater security, several locking mechanisms. lock, with active pins corresponding to the milled notch of the key, regatta readers, floating pins that act passively, and release by means of a ferromagnetic insert. Providing the key lock cylinder assembly with greater security, preventing it from being manipulated for opening without the corresponding key.

State of the prior art

At present, and as a reference to the state of the art, the use of locking cylinders that employ active pins that are placed in the rotating cylinder in a sliding manner, which, together with the counter pins and pushed by springs, block rotation, is known. In this way, with the insertion of a duly milled key, the pins move and align allowing the rotation of the cylinder.

However, this mechanism does not prevent the opening technique by the printing method, by means of which aluminum sheets are placed on a special key that, when inserted together in the lock cylinder, these sheets are deformed, leaving imprints of the combination. of pins mounted on the closing cylinder, thus achieving the opening. For this reason, the use of rotary cylinders that combine the previous mechanism with that of the use of a groove printed on the flat part of the blade of the key that is read by some pins that in correspondence with the groove of the key move is known. to align and allow cylinder rotation when the active pins are also aligned.

The present invention seeks to provide an improved locking cylinder and key that use the combination of these two methods, together with additional locking mechanisms for the rotary cylinder and thus increase the possibilities of variation in the key and guarantee greater locking 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.

Explanation of the invention and advantages

In contrast to this state of the art, the present invention refers to a lock cylinder with a key comprising a fixed lock body with a rotary cylinder inserted rotating in said fixed lock body and with a slot for inserting the key; with a plurality of active pins and counter pins loaded by spring and 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 milled notch of the key; being the reversible key with symmetrical blade faces and in its longitudinal direction with a slot read by a plurality of slot pins by means of slot readers, and said slot pins being mounted transversely on the rotating cylinder, with their axes axial substantially perpendicular to the direction of the active pins; in which there is a plurality of floating pins, which have a head in correspondence with the lateral notches of the racing pin, capable of being unlocked by lateral notches of the racing pins, said floating pins acting in the same direction as the pins assets.

This lock cylinder configuration with key allows a triple lock that prevents its violation more effectively and safely than in other locks. Thus, the undesired opening of the closing cylinder by the fraudulent techniques currently used is avoided.

Thanks to the configuration of double-diameter active 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 remains inserted in the rotor. This prevents a bumping key from being able to transmit enough movement to remove the counterpin from the rotor, protecting the cylinder against the bumping opening method. On the other hand, with the design of the shape that some pythons present as counter pythons, it is possible to give the anti-pick function as anti-impression to the cylinder.

In addition to the above, to increase the possibilities of variation in the key and guarantee greater security, the key is provided with a slot-shaped groove that extends longitudinally on the blade of the key. With this regatta it is achieved that some regatta pins mounted transversely in the rotating cylinder and that are driven towards the fixed closing body by springs, move laterally towards the inside of the rotating cylinder. This lateral displacement is achieved thanks to some race readers, which can be constituted by, for example, a lug 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 therefore unlocking the rotary cylinder. Thus, this configuration prevents the closing cylinder from opening by the printing method.

Additionally, to give greater security to the locking cylinder, there are floating pins in the rotating cylinder mounted radially in the vertical direction, and which are driven vertically towards the fixed locking body by springs to block the rotating cylinder. To unlock these floating pins, the race pins are equipped with lateral notches on their upper part which, once the race pins are aligned coming out of the fixed body, allow the floating pins to move towards the axis of the cylinder. rotary. In this way, an additional security mechanism is achieved against both the pick technique and the printing technique, achieving an additional lock that cannot be released without the appropriate key. In addition, thanks to the use of the usual pins in the fixed closing body and in the rotating cylinder and a steel ball also in the rotating cylinder, an anti-drill safety is achieved, the closing cylinder of the present invention being anti-bumping, anti-picking, anti-printing and anti-drilling.

In order for the blocking to occur through 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 with the help of springs they keep the floating pins in the body. fixed closure. Thus, thanks to this configuration, a safe movement is achieved without jamming, and by placing the heads of the floating pins in the lateral notches of the racing pins, a smooth release is achieved.

Another characteristic of the invention is that it is provided that there is at least one regatta pin that has a regatta reader constituted by a ferromagnetic insert capable of coming into contact with a ferromagnetic insert of the key. Thanks to this configuration, the race pin, instead of acting by means of a lug, is moved laterally by the action of a ferromagnetic insert located in the lower part of the race pin, which in the limit situation of penetration of the key produces the displacement of the race pin until its ferromagnetic insert is facing the ferromagnetic insert of the key. Thus, the race pin comes out of the fixed closing body and is aligned with the rest of the race pins to allow the floating pins to move thanks to the lateral notch. In this way, an additional security mechanism is achieved against the printing technique, providing greater security to the closing cylinder. As well as a personalization of the security system and a greater number of combinations for the closing cylinder.

It is provided that the floating pins are of different heights in correspondence with 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 as their head is placed inside the body. fixed closure. In order for them to move until their head sits in the side notches of the race pins, it is planned to make cavities in the key in correspondence with said floating pins, allowing them 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.

Finally, provision is made for there to be at least one fin on the key 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 unlock 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 lock cylinder.

Disclosure of a preferred embodiment

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 lock cylinder (1) with key (2) comprising a fixed lock body (3) with a rotary cylinder (4) rotatably inserted in said fixed locking body (3) and with a slot (5) for inserting the key (2); with a plurality of active pins (6) and counter pins (7) loaded by spring and mounted radially on the rotary cylinder (4) with their axial axes in 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 regatta (8) read by a plurality of regatta pins (9) by means of regatta readers (10), and said race pins (9) being transversely mounted on 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), which have a head (20) in correspondence with the lateral notches (11) of the race pin (9), capable of being unlocked by lateral notches (11) of the regatta pythons (9), said floating pythons (12) acting in the same direction as the active pythons (6).

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 closure body (3) by the action of springs, producing a first blockage of the rotating cylinder (4) that prevents 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 lock cylinder (1) of double cylinder of Figure 11, the active pins (6) and counter pins (7) are aligned to allow the rotation of the rotating cylinder (4).

However, even if this lock is released, it is also necessary to unlock the race pins (9) which are mounted transversely sliding in a direction substantially perpendicular to the direction of the active pins (6). Thus, these race pins (9) are blocked inside the fixed closure body (3) by the action of some springs (figure 2). A second blockage then occurs that prevents the impression opening technique. In order to unlock the regatta pins (9), it is necessary that the regatta readers (10) are aligned and come out of their housing in the fixed closure body (3). This lateral displacement is achieved by the movement produced by the race (8) in its interaction with the race readers (10), which by means of a lug (figure 6), according to the race combination (8) traced, achieve the alignment of the race pins (9) to unlock the rotation of the rotary cylinder (4), as can be seen in figure 3.

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 closing body. (3) remaining on the race 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 race pins (8), settling on them and producing the blockage. For the displacement of these floating pins (12) and the consequent unlocking, it is necessary that once the race pins (9) are aligned, some lateral notches (11) made in their upper part 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, with this additional lock, the locking cylinder is provided with greater security against picking, bumping and printing practices.

As can be seen in Figure 7, in order to provide greater combination possibilities for the key (2), it is planned that in some embodiments, for greater security, there is at least one regatta pin (9) with a regatta reader (10). constituted by a ferromagnetic insert (13) capable of coming into contact with a ferromagnetic insert (14) of the key (2). Thus, at first the regatta reader (9) would remain inside the closing body housing (3) (figure 9), and at the limit moment of penetration of the key (2), due to the action of the ferromagnetic insert (14) of the key (2), it causes the lateral displacement of the race pin (9) remaining facing said ferromagnetic insert (14) of the key (2) with the ferromagnetic insert (13) of the race pin (9). In this way, the unlocking of the rotary cylinder (4) is achieved (figure 10).

In figure 11, in the rotating cylinder (4) on the left, it can be seen how it has been unlocked by inserting the key (2) 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 tallest 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 closure body (3) and blocking the rotary cylinder (4). For unlocking to occur, the key (2) must, in addition to the correct regatta configuration (8), contain the correct cavities (15). Thus, the lock cylinder (1) is given more security, if possible, achieving a triple lock.

Additionally, to reinforce the anti-impression properties of the lock cylinder (1), it is planned that in some embodiments on 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 one in the upper part as the key (2) is symmetrical. In this way, the entry of a key or silver paper to carry out the printing method is difficult. 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).

Finally, to provide the lock cylinder (1) with anti-drilling properties, the use of pins is planned both in the fixed lock body (3) and in the rotating cylinder (4), in addition to a steel ball in the latter, which provides the lock cylinder (1) with greater resistance against the technique of forcing the lock cylinder with a drill.

Variations in materials, shape, size and arrangement of the component elements, described in a non-limiting manner, do not alter the essence of this invention, this being sufficient to proceed with its reproduction by an expert.
