    Protective assembly for lock cylinder OBJECT OF THE INVENTION
    The present invention relates to a protective assembly for a lock cylinder, whether of those with a European or conventional profile, protecting it against acts that attempt to violate the lock, such as the "bumping" technique, actions with a hook, drills, or other tool used for cylinder extraction, and thus, have access to the traction system (cam or pinon) that drives the lock.
    The cylinder protection assembly can be adapted to any lock or deadbolt in the market.
    BACKGROUND OF THE INVENTION
    Normally, most of the locks currently installed do not have sufficient security against vandal acts aimed at forcing them and having access to the place or things they guard. Every day new and faster and, to some extent, silent techniques emerge.
    In the case of cylinders or bulbs of the European profile type, the technique most used to violate them is the extraction of the cylinder to have access to the means of traction (cam or pinon), and thus, carry out the opening of the lock. This is because the cylinders of the European profile type, in their central part, are weakened by the box that forms the cam or pinon housing. This almost zero resistance to torsion is aggravated by a fixing hole that is arranged just below said box. Therefore, in front of a tool, the resistance to breakage is minimal so that the maneuver of extraction of the cylinder is practically silent.
    Other techniques commonly used are the action of a pick or the drilling of the drum of the cylinder or bulb, as well as the so-called "bumping" technique, which consists in inserting a key made with the lowest position into the cylinder drum to which the combination bolts of the cylinder commonly arrive, and hit it with an object, thus separating said combination bolts from the counter-bolts, thereby releasing the rotation of the key.

    On the other hand, protective lock cylinder assemblies are known, consisting of the use of a protective shield covering the part of the cylinder protruding outside. Said shield prevents tools from being used to carry out the extraction of the cylinder. Additionally, frontally, said protective shield can include a glula disc of the key that faces the drum of the cylinder, preventing the latter from being drilled. Commonly, both the protective shield and the glula disc of the key are made of hardened steel by a thermal treatment of cementation.
    However, while these known techniques prevent violent actions on the cylinder of the lock related to the extraction of the cylinder or drilling on its drum, they do not prevent the cylinder from being violated using, for example, a pick or the technique of " bumping. "
    For this reason, it is necessary to design a protective assembly for a lock cylinder that, in a simple and economical way, allows to overcome the above-mentioned disadvantages. That is, to provide the lock with comprehensive protection against all types of vandalism actions, be it anti-bumping, anti-hook, anti-drill, anti-extraction, etc.
    DESCRIPTION OF THE INVENTION
    The present invention is established and characterized in the independent revindication, while the dependent claims describe other features thereof.
    The object of the invention is a protection for a lock cylinder, applicable to any type of lock, which blocks said cylinder from the action of a pick or other element that is introduced into the drum of the cylinder for forcing. The technical problem to be solved is the vulnerability of the locks to vandal acts perpetrated on its cylinder or bulb that entails the unauthorized opening of said lock.
    In view of the foregoing, the present invention relates to a protective assembly for a lock cylinder, where the cylinder comprises a housing or canon in which a rotating drum or rotor receiving the key that opens the lock is mounted.

    The housing and the rotating drum comprise rows of radial combination holes facing each other where combination bolts are mounted that propitiate the opening of the lock when the key is inserted into the rotating drum.
    Likewise, the cylinder housing comprises at least a first portion of a radial locking bore that can be faced with one of the radial combination drills of the rotating drum at the start of drum rotation. A locking bolt is mounted in the radial locking hole that penetrates the corresponding radial combination hole when the rotating drum is attempted to be turned without the corresponding key, thereby blocking the cylinder, preventing unauthorized opening of the lock.
    As you can see, when you try to violate the lock, either using the "bumping" technique, a pick, or any other type of element other than the key that opens the lock, and successfully, you can move the combination bolts to a position that allows the rotation of the rotating drum, the beginning of said rotation will lead to the radial locking hole being faced with the corresponding radial combination drill of the rotating drum, causing part of the locking bolt to penetrate said radial combination hole by not receiving resistance from the corresponding combination bolt, thus blocking the cylinder, preventing unauthorized opening of the lock.
    On the other hand, advantageously, the assembly can comprise a bushing or protective canister where the cylinder housing is tightly inserted, thus protecting the integrity of the cylinder by preventing tools that propitiate its extraction from being attached thereto, leaving free access to the cam or pinon mechanism that drives the lock.
    In the same way, an anti-drill disk can be arranged in a punch made in a front wall of the protective sleeve, said anti-drill disk being facing the rotating drum, preventing the latter from being drilled to violate the lock.
    In this way, a protective assembly for a simple and functional lock cylinder is achieved, which can be coupled to any type of lock or bolt, protecting it from all types of vandal acts to which it can be subjected, that is, it is a protective set that achieves anti-bumping, anti-hook, anti-drill, anti-extraction, etc.

    DETAILED EXHIBITION OF THE INVENTION
    In view of the foregoing, the present invention relates to a protective assembly for a lock cylinder, which can be coupled to any type of lock or bolt.
    As shown in Figures 1 and 2, the protective assembly comprises a lock cylinder (1), either conventional (Figure 1) or of the European profile type (Figure 2), which in turn comprises a housing or canon (1.1 ) on which is mounted a rotating drum or rotor (1.2) receiving the key that opens the lock (not shown in the figures).
    It is seen in the figures from 3 to 6, that the housing (1.1) and the rotating drum (1.2) comprise rows of radial combination holes (1.11, 1.21)

    facing each other where combination bolts (3) are mounted that favor the opening and closing of the lock. Thus, starting from a closed state of the lock, figures 3 and 5, its opening is achieved when the key that opens said lock is inserted into the rotating drum (1.2), causing the combination bolts (3) to push against each other. - combination bolts (13) that keep the respective radial combination holes (1.11, 1.21) facing each other. Overcoming the force exerted by combination springs (14), the combination counter-bolts (13) are moved to a position where they allow the free rotation of the rotating drum (1.2), which causes the cam or pinon to operate (not shown in the figures) that opens the lock.
    On the other hand, as shown in figures 3 to 6, the housing (1.1) of the cylinder (1) comprises at least a first portion (1.31) of a radial locking bore (1.3), which, is confrontable with one of the radial combination drills (1.21) of the rotating drum (1.2) at the beginning of the drum rotation (1.2).
    Likewise, a locking bolt (4) is mounted on the radial locking hole (1.3), which is driven towards the rotating drum (1.2), preferably by means of a locking spring (5). Then, when the rotating drum (1.2) is rotated without the key that opens the lock, the locking bolt (4) penetrates the corresponding radial combination drill (1.21) when no resistance is found by the combination bolt (3 ). With which, the cylinder (1) is blocked, preventing it from continuing with its rotation and activating the cam or pinon that favors the opening of the lock. Only the introduction of the key that opens the lock on the rotating drum (1.2) manages to return the locking bolt (4) to its initial position. Said key, through the corresponding combination bolt (3), causes the locking bolt (4) to retract towards the radial locking bore (1.3), the resistance of the locking spring (5) being overcome.
    In this way, the possibilities that the lock can be opened with another element than the key that opens it are eliminated.
    In the figures, examples of realization of cylinders comprising a single radial locking bore (1.3) with their corresponding locking bolt (4) and locking spring (5) have been shown, however, more than one could be arranged.
    On the other hand, as seen in Figures 1 and 2, it is preferred that the casing (1.1) of the cylinder (1) be inserted, tightly, into a protective cap or canister (6). Asl, it is removed

    the possibility of operating on the outside of the cylinder (1) with a tool, with a view to violating the lock by removing said cylinder (1).
    Likewise, once the housing (1.1) of the cylinder (1) is inserted into the protective sleeve (6), the locking spring (5) can be arranged between the locking bolt (4) and a lateral cylindrical wall (6.1) of the protective sleeve (6), allowing, at all times, said locking bolt (4) to keep in contact with the rotating drum (1.2).
    As can be seen, in the embodiment shown in Figures 1, 3 and 4, that is, when the protective assembly employs a conventional cylinder, there is a possibility that not only a first portion of the radial locking hole (1.3) remains shaped in the housing
    (1.1) but that this be conformed in its entirety.
    However, when a cylinder of the European profile type is used, seen in Figures 2, 5 and 6, it is preferred that a jacket (8) be arranged between the housing (1.1) and the protective sleeve (6). The jacket (8) has an inner geometry that corresponds to the outside of the housing (1.1), and its outer geometry corresponds to the inner diameter of the protective sleeve (6). Thus, the jacket (8) comprises a second portion (1.32) of the radial locking hole (1.3). That is to say, the radial locking hole (1.3) is formed through the housing (1.1) and the sleeve (8), also ensuring that the locking spring (5) is arranged between the locking bolt (4) and the lateral cylindrical wall (6.1) of the protective sleeve (6).
    As shown in Figure 2, it is preferred that the shirt (8) is formed by two equal and complementary portions (8.1). In this way, the coupling of said jacket (8) to the outside of the housing (1.1) is facilitated.
    Additionally, it is preferred that the portions (8.1) comprise separate inner projections (8.11) that fit into respective holes (1.4) made on both sides of the housing
    (1.1). Thus, the confrontation of the union between the first (1.31) and the second portion (1.32) of the radial locking hole (1.3) remains immovable.
    Likewise, in another application in cylinders of the European profile type, embodiment not shown in the figures, the casing (1.1) and the jacket (8) can form the same piece, the radial locking hole (1.3) being practiced therein. in its entirety, as it happens in the realization of the conventional cylinder.

    On the other hand, in any of the previous embodiments, it is preferred that the protective sleeve (6) comprises an anterior wall (6.2) with a die cut (6.21) for an anti-drill disk (7). The die cut (6.21) with the anti-drill disc (7) face the rotating drum (1.2) when the casing (1.1) of the cylinder (1) is inserted into the protective sleeve (6).
    Preferably, both the protective sleeve (6) and the anti-drill disc (7) are made of hardened steel by a thermal cementing treatment. In this way, the surface hardness of both pieces is guaranteed, with a view to resisting the action of tools used to try to produce either the extraction of the cylinder (1) or the drilling of the anti-drill disc (7) respectively.
    On the other hand, in relation to the embodiment of Figure 1, it is preferred that the protective sleeve (6) is fixed to the housing (1.1) using at least one fixing means (9). In contrast, in the embodiment of Figure 2, it is preferred that the protective sleeve (6) is attached to the jacket (8), likewise, using at least one fixing means (9).
    As for the anchoring of the protective assembly to the lock, in the embodiment shown in Figure 1, it is preferred that a plate with lateral gliding grooves (11) where a clip (12) fits is arranged on the back of the cylinder (1). which prevents the removal of the cylinder (1) from the lock.
    As for the embodiment of the protective assembly shown in Figure 2, it is preferred that its anchoring to the lock be carried out through the jacket (8) by means of anchoring screws (10). The main function of the anchor bolts (10) of the lock security assembly is to effectively resist a possible attack perpetrated on the lock using the extraction method.
    In this way, the protective assembly can be coupled to any type of lock or bolt. It can be marketed next to the lock, or separately to be coupled to locks or bolts that are sold individually or are already placed, in this case, the cylinder of said lock or bolt is easily replaced by the protective assembly object of the present invention, providing the protection he did not have against vandalism actions of any kind.
