    A device and a system for the retention of an automatic door of an elevator car. The retention device, actuable in coordination with the actuator that procures the movement of a door leaf, comprises a rotating lever with a latch element that can adopt a retention and a release position. The lever is displaceable by a drive arm urged by a spring in an actuation direction but which mounts an accessory that allows to pull it, loading the spring, to keep it in a waiting position in which the latch element is in retention position. The device can be part of a system in which a pulling element links the drive arm, by the accessory, with the actuator by loading the spring with the door in the closed position and keeping the latch element in the latching position.

    DESCRIPTION
    A device and a system for the retention of an automatic door of an elevator car
     5
    Technical sector of the invention
    The invention relates to the field of elevators and more specifically to a device and a system for the retention of an automatic door of an elevator car, intended to prevent unwanted opening of said door, for example, when the elevator car It is not stopped at a landing on the installation. 10

    Background of the invention
    Several proposals are currently known to block the opening of an elevator car door when such opening can put the safety of users at risk. For example, it is not desirable that the cabin door can be opened if it is not stopped in coincidence with a landing of the installation, usually also equipped with a cabin access door.

    Such proposals are based on equipping the cabin with an actionable retention device when the cabin stops on a landing. When said action is mechanical, the retention device interacts with a fixed element of the installation, in the area of influence of each landing, so that said interaction only occurs when the cabin equipped with the retention device meets this fixed element This way of proceeding implies that the interaction should only occur when the cabin is stopped on a landing and should therefore be avoided that it occurs when cabin 25 is moving and travels through the well of the last installation without stopping by a landing.

    An object of the invention is an alternative retention device to those known to date prepared to overcome this obstacle.
     30
    The number of maneuvers that a device with these characteristics must perform is very high throughout the lifespan of an elevator installation.

    It is therefore also an objective of the present invention a robust retention device, without components or mechanisms that can be easily adjusted or which
    They can break. The device of the invention should achieve this objective by being also simple constructively and economically. It is also an objective of the invention that the device is compact, takes up little space and can be installed inside the cab operator without exceeding its dimensions.
     5
    Explanation of the invention.
    The proposed device is a device prepared to act in a coordinated manner with the actuator that seeks the movement of a door leaf between a closed position and an open position.
     10
    The device comprises a rotating lever provided with a latch element, the lever being able to rotate between two positions: one that has the latch element in a retention position (A) and another that has the latch element in a release position ( B).
     fifteen
    In essence, this device is characterized in that said lever is mounted on a mobile actuating arm that is requested by a spring in a direction of operation, capable of arranging a lever power arm within reach of a fixed element of the elevator installation to cause the rotation of said lever in a direction that moves the latch element from the retention position to the release position, and because the actuating arm is provided with an accessory to allow it to be pulled, loading the spring, to keep it in a waiting position in which the latch element is in its retention position.

    As will be explained below, providing the device with the ability to keep the actuation arm 25 in a waiting position allows the lever not to interfere with the fixed elements of the installation when the cab that mounts the retention device is in motion with its doors closed; or static, but not coinciding with a landing.

    In effect, the drive arm would by default adopt an extended position by means of the spring, but it is without clutch equipped with an accessory that allows it to be pulled, for example, when a cabin door is closed, so that it adopts a position of wait, collection, which will be calibrated so that the lever does not interact with fixed elements of the installation.
     35
    Spring means elastic force of something, which can be for example the elastic force of a spring or a rubber, capable of storing mechanical energy when subjected to a tensile or compression force and releasing it when these forces disappear or are reduced.
     5
    Preferably, the actuating arm and the lever form an articulated mechanism in a very compact plane of motion. The invention thus contemplates that the actuating arm is rotatable about an axis parallel to the axis of rotation of the lever and that the direction of rotation of the lever to move the associated latch element from its retention position (A) to its release position (B) is contrary to the direction of rotation 10 of the drive arm which is promoted by the spring.

    In a variant of interest, the device is auto portable so that it is easily installable in a cabin or inside the cabin door operator. In this case, it is envisaged that the device comprises a support plate, directly or indirectly fixed to the elevator car, on which the actuating arm is rotatably mounted, the loaded spring being located between a support point of the plate itself. support and said actuation arm.

    In a variant of interest, elastic means act on the lever that tend to be arranged so that the latch element adopts by default its retention position (A). When these elastic means have the shape of a spring that acts as a compression between the actuator arm and the lever, it contributes to the fact that the device is self-portable and that its operation and calibration does not depend, as regards the spring and the elastic means , of the relative position between the device and other elements of the cabin.

    And, although it is preferable that the device is self-portable, the invention also provides that this is not the case and also that the origin of the force that pulls the actuator arm to keep it in the waiting position may vary, however 30 special interest is the actuator of the door itself that you want to block.

    It is for this reason that the invention also relates to a retention system that is operable in a coordinated manner with the actuator that procures the movement of a door leaf between a closed position and an open position. The system is especially 35
    Ideal for doors with two or more leaves of the bus type, that is folding doors, divided into two or more leaves that open when articulated, compressing the door as an accordion.

    This system has an installable part in the elevator car, which comprises a drive arm 5; a movable part movable by pushing or dragging of the actuating arm and having a latch element, this movable part being able to move in a guided manner so that it can move the latch element between two positions: a holding position (A) and a release position (B), the drive arm being requested by a spring in a direction of operation; and a pulling element, 10 that links the actuator arm with the door actuator and pulls the actuator arm, loading the spring acting on it, when the door remains in its closed position, keeping the actuator arm in a waiting position by allowing the latch element of the moving part to adopt the retention position (A), interfering in the path of at least one door leaf, to prevent its opening maneuver 15.

    The system also has an installable part in an area of a landing of the elevator installation, with a cam element within reach of the moving part only when the pulling element releases the drive arm and it pushes, by means of the spring, into the direction of actuation to said mobile part moving it from its original position, and which causes a turn of the mobile part by contact with the cam by moving the associated latch element from its retention position (A) to its release position ( B), in which it does not interfere with the path of the door leaf, allowing its opening maneuver. 25

    In an embodiment of interest, the movable part is connected articulated to the actuating arm, as a lever, around a first axis of rotation, so that the associated latch element can perform a composite movement.
     30
    Preferably, the system comprises elastic means acting on the movable part in the direction that by default disposes the associated latch element in its retention position (A). Advantageously, when the movable part is joined articulated to the actuation arm, as a lever, the elastic means can be in the form of a spring that acts as a compression between the actuation arm and the movable part. 35
    In the event that the movable part is rotatably mounted on said driving arm, it is also of interest that said driving arm is rotatable about a second axis of rotation, the first and second axes of rotation being parallel between yes, and an axis of the actuator around which the door leaf can be folded, resulting in a mechanism articulated in a plane perpendicular to the plane of the door, easily installable 5 on the door lintel taking up little space.

    The pulling element can be a rod but also a flexible element, with a sector that supports or pulls an attachment of the actuating arm.
     10
    For example, this pulling element may be a belt, chain, cable, strip or tape.

    In one embodiment, the movable part comprises a stop, intended to cooperate with the cam element, which may be equipped with a wheel.
     fifteen
    To interact with the door leaf, the system comprises at least one slide formed in the guide or lintel guides of the cabin door through which the latch element can run between its two positions: the retention (A) and the release (B).

    In one form of interest, the latch element comprises two pins, each 20 intended to interact with a respective sheet of a double door, for example, by abutment with the pins of the sheets that slide inside the guide or guides of the door.

    Detailed description of the invention
    The device 1 of Fig. 1 basically comprises a movable part 3 with a latch element 4 that can be guided in relation to a support plate 9. The device 1 comprises a rotating actuating arm 2 about an axis turning 22 capable of moving the aforementioned mobile part 3 with its rotation, so that it can be pushed 10 to make it available to a fixed component of the installation, which will cause said mobile part 3 to rotate around an axis 33 sufficiently changing the position of the associated latch element 4 with respect to its initial position so that it will go from adopting a retention position to adopting a release position, as explained in detail below. fifteen

    The device is intended to be placed on the lintel of an elevator car door, oriented so that the aforementioned axes 22 and 33 remain vertical and that the device travels together with the cabin during the operation of the elevator.
     twenty
    In the constructive example of Fig. 1, the moving part 3 is a lever mounted rotatably, around the axis 33, in the actuating arm 2, rotating around its axis 22. Thus, the group formed by the drive arm 2 and the moving part, hereinafter referred to as lever 3, can take various positions, depending on the external forces that are applied on the drive arm 2 and on the lever 3. 25

    The device 1 of Fig. 1 comprises a spring 5 which in the example is a spring that acts as a compression and extends between a support 9a of the support plate 9 and the actuating arm 2 so that it would tend to rotate the drive arm 2 in the anti-clockwise direction around the axis 22. The drive arm 2 however comprises an accessory 7, in the form of a fixed pulley, which will allow a pulling element to keep the drive arm in the position illustrated in Fig. 2a, with spring 5 loaded. The device 1 further comprises elastic means 10, in the example in the form of a spring that acts as a compression between the actuating arm 2 and the lever 3 so that the lever 3 rotates around the axis 33 in the anti-clockwise sense, 35
    having a mechanical stop, not shown, which intervenes to keep the lever 3 in the position illustrated in Fig. 2a with respect to the drive arm 2. In this position, the associated latch element 4, visible in Fig. 2b, adopt a retention position (A).
     5
    The operation of the device is now explained by referring to the sequence of the drawings.

    The situation represented in Figs. 2a and 2b is one in which a pulling element 6 (visible in Fig. 5) keeps the actuating arm 2 in a retracted position, and by effect of the elastic means 10 the lever 3 is oriented so that the element of associated bolt 4 adopts its retention position (A), visible in Fig. 2b, and its power arm 3a, which mounts a wheel, is in a plane 100a, out of reach of the fixed elements of the installation, whose intrusion into the elevator shaft is represented by line 100b in Fig. 2b. Note that in the example (see Figs. 2b, 3b and 4b) the latch element 4 has two pins 4a and 4b, making it suitable to perform a retention function on two leaves of a double bus-type door, and that the plate of support 9 has sliding paths 9a and 9b so that these pins can project below support plate 9, in order to be able to be arranged in the path of the leaves of a door that slides immediately below this retention device 20 one.

    Starting from the situation illustrated in Figs. 2a and 2b, when the pulling element stops pulling the drive arm 2 it starts, driven by the spring 5, its rotation around the axis 22, in the direction indicated by the arrow in Fig. 3a, extending and moving with it 25 to the lever 3 which, due to the effect of the elastic means 10, its relative position with respect to the actuating arm 2 would not vary. Fig. 3a shows this situation, being able to observe that now the arm of power 3a of the lever 3 is arranged in a plane 100c, within reach of the fixed elements of the installation represented by the line 100b.
     30
    As explained below, the invention provides that the pulling element is a belt that rests on the accessory 7 of the drive arm 2, the belt being linked to an operator of the elevator car door, in particular to a component that is it moves when the door is operated in an opening maneuver in such a way that it loosen or relax said belt and allows the rotation of the operating lever 2 when the door 35 moves
    in the sense of its opening.

    The position of Figs. 3a and 3b will be altered in the event that, when the drive arm 2 is extended, the power arm 3a of the lever 3 stops with a fixed element of the installation, such as a cam element 13 schematically illustrated in 5 Fig. 4a.

    This cam element 13 will be intentionally arranged at the same level as the power arm 3a of the lever 3 when the cabin stops at a landing. Consequently, when the cabin door is operated and thereby the drive arm 2 is released by stopping the power arm 3a of the lever 3 with the cam element 13 said lever 3 will rotate with respect to the drive arm 2 and around the axis 22 in the opposite direction to that promoted by the elastic means 10, as indicated by the arrow of Fig. 4a, moving the associated latch element 4 to a release position (B), illustrated in Fig. 4b. fifteen

    The closing operation of the door will cause the actuating arm 2 to return to its retracted position, the spring 5 being loaded, and that by effect of the elastic means 10, the lever 3 automatically adopts the position represented in Fig. 2a, that is with the latch element in the retention position (A). twenty

    Fig. 5 shows the device of Fig. 1 installed inside a box that houses an actuator 12 of a door of an elevator car, below which a sliding guide 15 for the leaves are placed and / or formed. of the door. Through the guide 15, pins, bolts or protrusions 17 associated with the leaves of the door will slide, for example, the central leaves 11a, 11b of a double door, bus type. The device 1 is installed so that the axes of rotation 22 and 33 are vertical, parallel to the axis of rotation 12a around which the driven sheets can be folded away by dragging said central sheets 11a and 11b (shown schematically in Fig. 6). 30

    Said Fig. 6 is a partial view of this guide 15, and specifically shows that it comprises two slides 14, coinciding with the slides 9a and 9b of the plate 9 (not visible in Fig. 6), between which the pins 4a, 4b run from which the latch element 4 of the device 1 is provided. Depending on the instantaneous position of these pins 4a, 4b 35
    they will interfere in the trajectory of the protuberances 17a, 17b associated with the leaves 11a and 11b of the door. In the example, the latch element being in its retention position (A), the pins 4a and 4b will prevent the protuberances 17a, 17b associated with the leaves 11a and 11b of the door from sliding by the guide, consequently blocking its opening. 5
