    [0001] Electromechanical lock for community doors
    [0002] TECHNICAL FIELD
    [0003] The present invention relates to a latch retaining the latch of a lock, of those used to facilitate remote access through a door in common areas of neighboring communities, portals, urbanizations, shared spaces or offices, which has a box in which the lock latch is locked by the action of a retractable key that travels rectilinearly inside and inside the box and is electrically actuated.
    [0004]
    [0005] BACKGROUND OF THE INVENTION
    [0006]
    [0007] Several models of locks for portals and common areas of neighboring communities are known. They are characterized in that they involve a latch that is retracted by a handle or by a key; This latch can be simple or incorporate a slip.
    [0008]
    [0009] This type of lock requires a strike equipped with means for locking and unlocking the latch commanded remotely, usually by electrical means.
    [0010]
    [0011] Typically, the lock is placed on the door with the operating handle on the inside of the enclosure to be closed and the lock on the frame on which the door is mounted. This implies a limitation of space to place the strike, since its assembly must have measures smaller than the width of the frame.
    [0012]
    [0013] The strikes of this type include a box with an electromechanical mechanism for locking the latch constituted by a pivot key that closes the space in which the latch is inserted.
    [0014]
    [0015] This key pivots on a vertical axis to allow the entry or exit of the latch and incorporates means that immobilize its ability to pivot on the vertical axis to block the latch inside the lock.
    [0016]
    [0017] These means of immobilization of the key are actuated electrically, so that the mechanism can be operated remotely.
    [0018]
    [0019] Examples of this type of strike are described in US259394, FR0607241 or ES201631017 and in utility models No. U269086, U1158664 or U1164585.
    [0020]
    [0021] The pivot key is an appropriate technical solution to achieve strikes compact that can be incorporated in frames of small thickness, so they are in high demand, however, they suffer from a significant problem.
    [0022]
    [0023] They are vulnerable to a forced opening by impact, since, when the door is knocked strongly from the outside in a direction perpendicular to the plane of movement of the latch, the pivot key acts as a lever arm and the force exerted is transmitted to the locking element of the key, it is enough that it is superior to the one that can mechanically resist this locking element to break it or deform it, freeing the movement of the key, which would open the door. Since the key locking element is a small piece and is sized to block or release the movement of a larger piece and not to withstand large stresses, the force necessary to overcome its elastic limit is small.
    [0024]
    [0025] Therefore, it would be beneficial to develop a strike where the key did not pivot on a vertical axis, so that, in the locked position of the latch, the force exerted towards other internal components of the mechanism did not act as a relinquished lever. All this taking into account the limitation of space that represents the placement of the strike in the door frame.
    [0026]
    [0027] DESCRIPTION OF THE INVENTION
    [0028]
    [0029] The present invention relates to an electromechanical striker that solves the objective problem posed by presenting a configuration in which the key, instead of pivoting on a vertical axis, retracts into the interior of the box following a straight path.
    [0030]
    [0031] In this way, the application of a force in the normal direction to the plane of the key is not transmitted to other mechanisms of the lock.
    [0032]
    [0033] Consequently, the only way to forcefully extract the latch from the strike is by exerting an external force capable of breaking the key itself by shearing, which is far superior to that necessary to deform or break the axis of rotation or the blocking elements of a pivot key.
    [0034]
    [0035] Specifically, the new strike is constituted by a box in whose interior there is a retractable key that has horizontal slides crossed by pivots fixed to the box, in such a way that it can move towards the inside of the box, leaving the mouth open by which the latch is inserted.
    [0036]
    [0037] Since the direction of movement of the retractable key is perpendicular to the direction of an impact to force the exit of the latch from its seat in the strike, this force is not possible components in the direction of the key movement, so it is impossible to move it and all that force will be absorbed by the retractable key itself and the set of the box where it is housed.
    [0038]
    [0039] The retractable key is displaced by a lever arm that rotates on a shaft integral to the housing and which has an end associated with the piston of a solenoid with the intermediation of a connecting rod, and another with an outstanding pivot that of the key and on the which at the same time acts a spring which, with the striker in the resting state, keeps the retractable key in the locked position of the latch.
    [0040]
    [0041] The retractable key incorporates in its face oriented towards the entrance of the latch a protuberance with an inclined plane that facilitates the retraction of the key when the latch impacts on it when the door is closed. Once the latch reaches its housing inside the strike and exceeds the position of the key, the spring returns the key to the closed position, blocking the exit of the latch.
    [0042]
    [0043] Another novel aspect of the invention is that it incorporates an intermediate partition that separates the interior of the box into two spaces, one corresponding to the area where the retractable key is located and another in which the mechanism that moves the retractable key is located, is that is to say, the lever arm, the connecting rod, the plunger and the pivot of the key, for which, this partition has a step as a slide for the pivot of the key.
    [0044]
    [0045] This partition reinforces the structure of the strike by increasing its resistance to a forced opening of the same.
    [0046]
    [0047] DESCRIPTION OF THE DRAWINGS
    [0048]
    [0049] In order to illustrate how far we have set forth, the description of a sheet of drawings in which an example of embodiment of the invention has been represented is attached.
    [0050]
    [0051] In said drawings, Figure 1 represents a view of a side view of the new strike in the rest position, with the box open and in which the intermediate partition is indicated in a broken line.
    [0052]
    [0053] Figure 2 represents a view of a side view of the new strike with the retractable key retracted and in which the intermediate partition is indicated in a broken line.

    [0088] DESCRIPTION OF A PREFERRED EMBODIMENT
    [0089]
    [0090] The novel electromechanical lock for community doors is constituted by a box (1) inside which a retractable key (2) with horizontal slides (3) crossed by some pivots of the box (4) that is displaced by an arm lever (5) which rotates on a shaft (6) integral with the housing (1) and has an end associated with the plunger (7) of a solenoid (8) with the intermediation of a connecting rod (9), and another end associated with a pivot of the key (10) on which at the same time a spring (11) acts which, with the striker in the rest state, keeps the retractable key (2) in the locked position of the latch, closing the Mouth of the strike (14).
    [0091] The retractable key (2) incorporates in its face oriented towards the entrance of the latch, a protuberance with an inclined plane (12).
    [0092]
    [0093] The box (1) has an intermediate partition (13) that separates its interior into two spaces, one corresponding to the area where the retractable key (2) is located and another in which the lever arm (5) is located, the connecting rod (9) and the plunger (7). This intermediate partition (13) has a passage (15) as a slide through which it passes through the key of the key (10).
    [0094]
    [0095] The operation of the device is as follows:
    [0096]
    [0097] When the solenoid (8) receives current, the plunger (7) moves inwardly and pivots the lever arm (5) on its axis (6), so that the end of the arm strikes the pivot of the key (10) exerting on the retractable key (2) a force in the direction of the slide of the box (3) and in the opposite direction to the force of the spring (11). As the force exerted by the lever arm (5) is of greater magnitude than that of the spring (11), the retractable key (2) is moved towards the inside of the box (1), releasing the mouth of the lock (14) , with which the latch can leave this.
    [0098]
    [0099] As soon as the solenoid (8) stops receiving power, the lever arm (5) stops exerting force and the spring (11) removes the retractable key (2) from inside the box (1), blocking the mouth of the locksmith (14).
    [0100]
    [0101] When the door is closed, the lock latch impacts the inclined plane (12) that facilitates the key retraction. Once the latch arrives at its housing inside the strike and exceeds the position of the key, the spring (11) returns the key to the closed position, blocking the exit of the latch.
