    [0002] Double Handle Electric Lock Set
    [0004] Field of the invention
    [0005] This invention concerns an automatic lock assembly of those intended for electric opening controlled by a strike and a lock that allows it to be opened by means of mechanical elements such as a handle, a cylinder and a key and by means of an electric impulse.
    [0007] The lock of this set consists of a double latch, a locking activating pin and a bell ring. In turn, the lock assembly of the present invention comprises a strike that allows, by means of a rotating fork operated through an electromagnet, the longitudinal sliding of a sliding occluder that will allow or not the insertion of the locking, locking or unlocking activating pin. the lock.
    [0009] Prior state of the art
    [0010] At present and as a reference to the state of the art, it is known to use sets of electric locks that each time the door is closed project or actuate the lever and that due to the configuration of said lever require a high enough force to compensating for the usual action of the spring or spring against which it acts, and requiring an excessive force compensation that can even lead to a malfunction of the mechanism. Furthermore, in this type of locks it is necessary to use more than one element against which the spring acts in order to compensate for the high forces generated in the mechanism and actuate the lock. This type of mechanism is described, for example, in Patent No. 201431161.
    [0012] On the contrary, the electric lock assembly of the present invention allows the use of electromagnets with little axis travel since the mechanism incorporated in the strike, due to its configuration, generates very small or almost negligible torques to overcome, thus achieving and, with an electromagnet with little axis travel, the movement of the rotating fork which, by means of its wedge stop wall, unlocks the lock.
    [0014] On the other hand, in the sets of double-handle electric locks used today, the locking activator pin, in its relationship with the strike mechanism, requires a high force in its spring or impeller. This fact also translates into the length of their inclined planes and all this causes electric locks to have a hard spring and a critical clearance, that is, they are only capable of absorbing clearance variations of an estimated range between 2.5 millimeters and 4 millimeters. This is aggravated by the fact that, by having to use a door closer, the greater its force in the closing maneuver of the door, it supposes on the other hand being a hindrance for the door opening maneuver, which generates by consequent problems in the possibility of installing the lock in the usual maneuver of use.
    [0016] In addition, sometimes, when working with such critical clearance ranges (variation of only 1.5 millimeters) and, for example, due to temperature variations that occur at certain times of the year such as summer, the dimensions of the door and a malfunction of the lock may occur.
    [0018] Explanation of the invention and advantages
    [0019] Against this state of the art, the present invention refers to a double handle electric lock assembly composed of a lock with an activating locking pin that vertically moves the bell between a locking position with respect to the position of use. o release of the movement of the double latch and that acts opposite a strike located in the door frame and container of the receiving window of the double latch and the receiving window of the locking activating pin in which in the striker the receiving window of the pin The locking activator comprises a spring loaded sliding occluder and provided with a lateral step capable of facing the wedge abutment wall of the rotating fork comprising a wedge and an activating arm capable of varying its angular position according to the excited state or not from the electromagnet.
    [0020] Thanks to this configuration, the door is opened by the user and it is necessary to use lower force door closers. Because the force that the sliding occluder spring has to withstand is less due to the configuration of the rotating yoke, a lower resistance spring is required. Additionally, it is possible to work in a greater range of clearances (between 0 and 6 millimeters) unlike in the sets of locks currently used, which have a high sensitivity to clearance and at the same time are very hard, which guarantees correct operation. of the lock assembly in different conditions and / or assemblies.
    [0022] Another feature of the invention is that the wedge of the swivel fork has a wedge abutment wall and a wedge sliding wall.
    [0023] Thanks to this configuration, the force to be applied to unlock the lock is much less than in the current lock assemblies commonly used, allowing the use of smaller electromagnets and ensuring a correct improvement of the lock assembly.
    [0025] Another characteristic of the present invention is that the activator arm is dimensionable in length and in accordance with the stroke of the electromagnet to be used.
    [0026] Thanks to this particularity, the lock assembly is more versatile since with different dimensions of the electromagnet, and depending on its strength, it is possible to vary the length of the activating arm and obtain small torques in the mechanism.
    [0028] Another characteristic of the invention is that, with the rotating fork in the angular unlock position, the spring force of the locking activating pin is opposed to the spring force of the sliding occluder and the advance of the locking activating pin raises the bell ring past to the unlock position.
    [0029] Thus, the force of the occluding spring only has to be slightly less than the force of the spring or driver of the locking activating pin in order to raise the bell and thus unlock the lock. Therefore, due to the configuration, a small force is sufficient to overcome the spring force of the sliding occluder.
    [0031] Finally, another particularity of the invention is that the inclusion of a rotating piece with a slotted prism accessible by the edge of the lock and a flange with a cam configuration supported on a projection of the bell and capable of being rotatably positioned while keeping the edge elevated is foreseen. bell ring in the lock unlocking situation.
    [0032] Thanks to the rotating part it is possible to unlock the lock depending on the needs in different situations. That is, there are times of the day when a constant influx of people is expected in a portal, for example, a move, and thanks to the arrangement of the rotating part with a slotted prism accessible by the edge of the lock and a flange of Cam configuration supported by a projection of the bell it is possible to lock the lock without the unlocking of the lock depending on the locking activating pin and without the need to disturb an external person so that they have to open the door constantly due to the continuous influx of people. On the contrary, at certain times, such as at night, fewer people are expected to enter, obtaining the possibility of locking the lock with the activating locking pin.

    [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 set of electric lock (1) with a double handle (5) composed of a lock (2) with a Activating locking pin (3) that vertically moves the bell (4) from the position of use between a position of locking or releasing the movement of the double latch (5) and acting opposite a strike (6) located on the the door frame and container for the receiving window of the double latch (7) and the receiving window of the locking activating pin (8) in which in the striker (6) the receiving window of the locking activating pin (8) has a sliding occluder (9) loaded with spring (10) and provided with a lateral step (11) capable of facing the wedge stop wall (12b) of the rotating fork (12) comprising a wedge (12a) and an activator arm (12d) capable of varying its angular position according to the excited state or not of the electromagnet (13).
    [0081] As can be seen in both Figure 1 and Figure 4 in more detail, when the electromagnet (13) is not activated and therefore is not in contact with the activating arm (12d) of the rotating fork (12), the The lock (2) is in the locked position, the wedge abutment wall (12c) preventing the longitudinal sliding of the sliding occluder (9) as it acts as a stop with the lateral step (11). As shown in Figures 2 and 3 and the respective Figures 5 and 6 corresponding to an intermediate locking position and to the unlock position of the lock (2), at the moment in which the electromagnet (13) is activated and makes contact with the activating arm (12d) of the rotating fork (12) and, thanks to its axis of rotation centered on the wedge (12a), the rotating fork (12) tilts and moves through the sliding wedge wall (12d) longitudinally on the sliding occluder (9) loaded with spring (10), overcoming the lateral step (11), to the unlock position of the lock (2). It should be mentioned that said lateral step (11), as can be seen in Figure 7, is located on one side of the sliding occluder (10), that is, off-center with respect to the central axis of the sliding occluder (10). Thus, and due to the configuration of the rotating fork (12) having a wedge stop wall (12b) and a wedge sliding wall (12c), it is possible with a very small force produced by the electromagnet (13) of activation unlock the lock (2).
    [0083] On the other hand, since the activating arm (12d) is dimensionable in length and in accordance with the stroke of the electromagnet (13) to be used and, which can be electrical or electronic and whose circuit is capable of being activated by a remote control, It allows to have less axis travel and a use of electromagnets of a smaller size. Therefore, in this way a very versatile lock assembly (1) is obtained by means of which with different dimensions of the electromagnet (13) and depending on the force of this it is possible to vary the length of the activating arm (12b) of the fork rotary (12) and obtain in the mechanism very low torques in the whole.
    [0085] Furthermore, when the rotating yoke (12) is in the angular unlocked position, the force of the spring of the locking activating pin (3) is opposed to the force of the spring (10) of the sliding occluder (9) and the advance of the pin lock activator (3) raises the bell (4) into the locked position. Thus, the force of the spring (10) of the sliding occluder (9) has to be only slightly less than the force of the spring or impeller of the locking activating pin (3) so that the bell (4) rises vertically and thus unlock the lock (2). Therefore, with a very small force it is sufficient to overcome the force of the actuator locking pin (3), which ensures a smooth and reliable closing.
    [0087] Subsequently, as can be seen in figure 8, the inclusion of a rotating piece (14) with a slotted prism (14a) accessible through the edge of the lock (2) and a flange (14b) with a configuration in cam resting on a projection of the bell (4a) and capable of being rotatably positioned, keeping the bell raised in the lock release situation. In this way, in situations in which a continuous influx or constant passage of people is foreseen, thanks to the rotating part (14) composed of a slotted prism (14a) and a flange (14b) with a cam configuration that rests on a projection of the bell (4a) and, as it is accessible by the edge of the lock (2), the bell (4) remains raised in the unlock position of the lock (2) and users can enter without the need to having to bother someone else to open the door for them. Additionally, and due to the possibility of turning the rotating part (14) in situations in which a lesser influx of people to the portal is foreseen, such as at night, it is possible to keep the bell (4) lowered, that is to say , in the lock locking situation (2) and in which the lock release (2) is achieved with the activation of the lock activating pin (3).
    [0089] Spatial allusions (top-bottom, top-bottom, front-back ...) must be interpreted as referring to the mechanism in its operating position; In this case, as it is a lock, it will be located in a vertical position on the door and at the same level as the vertical strike located on the door frame.
    [0091] 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.
