    [0002] Bolt assembly
    [0004] Field of the invention
    [0005] This invention concerns a bolt assembly for doors or windows made up of a bolt and a strike and in which the bolt comprises a displaceable pin in the bolt body between an opening and closing position, as well as the incorporation of an alarm, providing greater security and a quiet movement.
    [0007] Prior state of the art
    [0008] At present and as a reference to the state of the art, it is common and known to use bolts with movement of a pin to provide the closure with the strike. In this type of bolt there is an unlocking button to freely move the bolt or latch and actuation by key. For key operation, these locks use assembled parts requiring at least one part for locking and another for moving the pin. Consequently, there is greater wear between the parts and over time they hit or deteriorate the bolt.
    [0009] In addition, this type of bolt is weaker with respect to resistance to frontal loads. Another drawback is that, with the use of elements such as cams, these bolts are louder as the pin advances.
    [0011] Another of the solutions adopted is the use of a gear pinion or crown gear to move the pin that incorporates a rack, in this way they are less noisy, but they still need additional parts for locking, producing gaps between the elements with wear. in its usual use. In addition, in this case the cylinder is the one that resists the entire front load, producing a malfunction over time.
    [0013] To provide greater security, there are locks with built-in alarms in the body of the bolt itself. However, in the event of a malfunction, access to them is complicated, requiring the disassembly of the entire lock, as well as the assembly and assembly of the same.
    [0014] Another solution adopted is the incorporation of an acoustic alarm to a printed circuit included in the lock that, with an additional vibration sensor, gives warning in the event that the lock is forced, however, this type of alarm is only applied to electromechanical alarms that If there is a failure in the sensor or the alarm, they would need to replace the entire printed circuit of the lock.
    [0016] Explanation of the invention and advantages
    [0017] Against this state of the art, the present invention refers to a bolt assembly for doors or windows made up of a bolt, a strike and a closing casing, in which the bolt comprises a displaceable pin in the body of the lock between an opening and closing position, operable manually by means of a lever connected to the bolt and an unlocking pushbutton or by means of a key, and which has a locking cylinder with an intermediate locking disc and, attached to said locking disc, a displacement disc with at least two gear teeth; with said locking cylinder associated with the pin, said pin having a stepped groove with at least two locking recesses with a locking surface in correspondence with the lateral surface of the locking disc, and with engagement holes interspersed with said locking recesses and in correspondence with the surface of the gear teeth.
    [0019] This configuration allows that, with the use of a single piece, the bolt, through the locking cylinder, performs the function of locking the pin and moving it between the open and closed positions. Thanks to the locking disk, the locking cylinder is engaged in the stepped groove inside the locking recess, and with the rotation of the locking cylinder given by the key, the displacement disk engages with the engagement holes of the pin, displacing it to the position of opening or closing the bolt. Thus, with the use of a single piece that performs both the locking function and the opening and closing of the bolt, problems of play and wear of parts that can finally hit and cause the bolt to deteriorate are avoided. Furthermore, this configuration gives the bolt greater resistance to frontal forces than in the already known bolts, also preventing the lock cylinder from resisting this type of loads and thus providing greater security.
    [0020] Another advantage of this configuration is that thanks to the correspondence between the locking surface and the lateral surface of the locking disc, and the correspondence between the configuration of the gear teeth and the mesh holes of the pin, in the cylinder turning maneuver blocker for opening and closing, the bolt is quieter avoiding the knock of other realizations. In addition, the gear disc prevents the lock cylinder deviates or comes out of its locked position during rotation. This avoids the need for other locking elements typical of latches with gear rings that complicate manufacture and assembly and can cause damage to the gear teeth as they resist the locking force against the rack of the pin, and the present being Quieter invention by having a continuous contact surface.
    [0021] Another additional advantage is that, thanks to the use of at least two locking recesses, the pin can have several locking positions depending on the needs of each installation, providing greater regulation than in other locks of the state of the art and doing more safe and versatile bolt assembly.
    [0023] A window in the body of the bolt protects the locking cylinder, this window being only necessary to associate the locking disc or the meshing teeth with the stepped grooving of the pin. In this way, the bolt is more compact and secure, avoiding deterioration of the internal parts.
    [0025] Another characteristic of the invention is that the locking disc has a locking edge and on its opposite side a mesh recess. Thanks to this configuration, the locking disc better adapts to the stepped grooving, producing an adjustment without tightening and, thanks to the mesh recess, it allows the continuous rotation of the locking cylinder, facilitating the operation of meshing the meshing teeth with the pin mesh holes.
    [0027] It is envisaged that an alarm of dimensions corresponding to said housing recess is incorporated in the housing recess of the closure housing. Thus, additional security is provided to the bolt assembly, and the location of the alarm in it is facilitated thanks to the housing recess of the closing housing, the alarm being easily attachable and removable and avoiding having to disassemble the complete bolt in the event that any component of the alarm is repaired and / or put to charge the alarm battery.
    [0029] The union of the aforementioned alarm is attached to the bolt by mechanical means, thus facilitating its assembly and replacement without modifying the aesthetics of the bolt. This can be done by side screwing so as not to mark the door, or by including ribs in the recess that allow the incorporation of the alarm by sliding, or by incorporating tabs in the alarm that allow it to be clipped into the corresponding housings provided in the housing box.
    [0030] Said alarm is activated by a vibration sensor, that is, by means of a rod inserted in a spring, the vibration that will trigger the alarm when it touches said spring is controlled. In this way, the lock is given greater security to prevent it from being forced, leaving the sensor adjusted to what could be a vandal attack on the door. In addition, said sensor is integrated into the alarm itself and in the event of a malfunction or battery recharging, the alarm could be replaced without having to remove the bolt.
    [0032] Finally, another characteristic of the invention is that the locking cylinder rotates at least two turns to move the pin from the open position to the final closed position. Thus, greater security is provided to the bolt against its struggle, with several locking positions.

    [0073] Presentation of a preferred embodiment
    [0074] With regard to the above-listed drawings and references, a preferred arrangement of the object of the invention is illustrated in the attached drawings, referring to a bolt assembly for doors or windows made up of a bolt (1), a strike (2) and a closing casing (15), in which the bolt (1) comprises a pin (3) movable in the bolt body (4) between an opening and closing position, manually operable by means of a lever (5) connected to the pin (3) and an unlocking button (10) or by means of a key, and which has a locking cylinder (6) with an intermediate locking disc (7) and attached to said locking disc (7) a displacement disc (8) with at least two gear teeth (9); with said locking cylinder (6) associated with the pin (3), said pin (3) having a stepped groove (12) with at least two locking recesses (13) with a locking surface (18) in correspondence with the lateral surface of the locking disk (7), and with engagement holes (14) interspersed with said locking recesses (13) and in correspondence with the surface of the engagement teeth (9).
    [0075] As can be seen in figure 1, the pin (3) is inserted movably in the body of the bolt (4) to act in closing the door or window in the final closing position thanks to the strike (2) (bolt mounted in figure 2). Said final closing position of the pin (3) can be obtained by the free movement of the pin (3) by means of the lever (5), once the mechanism is unlocked by pressing the release button (10) which makes the locking cylinder (6) comes out of the locking recess (13) (figure 6); or the movement of the pin (3) for the opening or closing of the bolt (1) occurs by means of the actuation of the locking cylinder (6) which is actuated by a key, thanks to a keyway in which the key associated to the cylinder fits the lock and that it will rotate to produce the rotation of the locking cylinder (6) and therefore achieve the aforementioned opening or closing of the bolt (1), as can be seen in the sectional view of figure 3. For this purpose the locking cylinder (6) has an intermediate locking disk (7) that, through a window (11) made in the body of the bolt (4), is fitted into the locking recesses (13) made in the stepped groove (12) of the pin (3), thus blocking the movement of the pin (3) and thanks to the action of a spring that keeps pressing the locking cylinder (6) against the pin (3), in this way, the locking cylinder (6) remains fitted in the pin (3) preventing its movement (figures 4 and 5).
    [0076] When you want to achieve the displacement of the pin (3) for the opening or closing of the bolt (1), by turning a key the locking cylinder (6) is actuated by turning it until the gear teeth (9) of the displacement disk (8) mesh with the engagement holes (14) made in the stepped grooving (12), at that time with the rotation of the locking cylinder (6) the pin (3) moves to the next locking recess (13 ), the bolt (1) being locked in the next opening or closing position, this displacement disc (8) may also be an attachment to the locking disc (7) or simply the gear teeth (9) form part of the locking disc (7) but axially displaced with respect to this to engage with the engagement holes (14) also producing the displacement of the pin (3).
    [0077] Therefore, unlike other embodiments, the locking and displacement of the pin (3) for the opening or closing of the bolt (1) is achieved with a single piece, thanks to the configuration of the locking cylinder (6) that is manufactured entirely with the blocking disk (7) and displacement disk (8), thus avoiding wear between parts that could cause them to hit each other and the malfunction or fall of the pin, thus being more durable and safe. Furthermore, by acting through the window (11) of the bolt body (4), the locking cylinder (6) is protected from the entry of dirt or particles that prevent the correct movement of the pin (3), centering the locking cylinder (6) and ensuring correct operation. In addition, it makes the unit more resistant to frontal forces, preventing the cylinder cylinder from absorbing the forces.
    [0078] Another advantage of this configuration is that, thanks to the fact that the locking surface (18) of the locking recess (13) corresponds to the lateral surface of the locking disc (7), the movement is smooth and silent (surfaces in bold in Figures 4 and 5). The configuration of the engagement holes (14) of the pin (3), which have a surface in correspondence with the engagement teeth (9) (Figures 7, 8 and 9), also contributes to this same end, providing the bolt assembly ( 1) of a silent mechanism.
    [0080] The use of at least two locking recesses (13) ensures the final closing position or the initial opening position of the pin, but as can be seen in Figures 4, 5 and 6, to provide greater security, preferably the locking cylinder (6) rotates at least two turns to move the pin (3) from the open position to the final closed position, with at least three locking recesses (13) being necessary. In this way, more intermediate locking positions of the pin (3) will be given, making it more difficult to force or manipulate the bolt (1) and making the assembly more secure.
    [0082] As can be seen in Figure 5, the locking disc (7) has a locking edge (20) that allows the locking disc to better adapt to the stepped grooving (12) to avoid a tight fit. And on its opposite side it has a mesh recess (21) that allows the continuous rotation of the locking cylinder, facilitating the operation of the mesh teeth (9) with the mesh holes (14) of the pin (3), producing a smooth and silent movement during movement of the pin (3).
    [0084] To provide greater security, as can be seen in figure 1, there is a housing recess (16) in the closing casing (15) of the bolt (1) for the incorporation of an alarm (17) (figure 2), which preferably it is activated by a vibration sensor integrated in the alarm itself. This vibration sensor consists of a rod inside a spring that, with the vibration derived from the manipulation of the bolt when touching said rod, the spring activates the audible alarm, and the positions can be varied so that it does not jump easily in the case of the simple action of Opening and closing. Likewise, this alarm has an on and off button to connect and disconnect it easily.
    [0085] This alarm (17) is attached to the bolt (1) by means of the mechanical joining means (19) usually used, which may be by means of a lateral screw fastening such as that in figure 1 to facilitate assembly and avoid marking the door. Or others such as by the inclusion of ribs in the recess that allow the incorporation of the alarm by sliding, or by incorporating tabs in the alarm that allow it to be clipped into the corresponding housings provided in the housing recess.
    [0087] Thanks to this configuration, the bolt is given greater security and versatility, allowing it to be coupled or uncoupled from an alarm that is activated by vibration and which can be easily replaced in case of failure without the need to dismantle the complete bolt.
    [0089] 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.
