Description

[0001] The present invention relates to an actuating device for a building closure element and a building closure element with this actuating device.

[0002] Within the technical field of building envelope automation, various solutions for opening building envelope elements, such as windows, by means of motorized mechanisms are known. In particular, actuating devices of the type comprising a joint mechanism and an actuator are known.

[0003] The known hinge systems are generally designed as scissor or parallelogram mechanisms and are mainly used in tilt-and-turn windows, windows with transoms, or more generally, windows with hinges mounted in the lower part of the frame. In some embodiments, the windows can be designed as pivot windows, meaning they are hinged in an intermediate section of the frame.

[0004] The joint mechanism can, for example, be designed as a scissor mechanism. The opening and closing of the scissor mechanism is achieved by means of an actuator that is able to move the two arms of the scissors towards and away from each other by moving a slider.

[0005] The known actuating devices have the disadvantage that the joint mechanism can be subjected to stresses, mechanical strains, and overloads, for example, due to the application of forces greater than those for which the mechanism was designed, improper use, rough handling, wear and tear of the parts through prolonged use, etc. This can cause deformation or breakage of the components, a reduction in load-bearing capacity, and possibly failure of the mechanism.

[0006] The joint mechanism can become unstable, for example due to loosening of threaded connections or deformation of the frame due to overloading.

[0007] In cases where the joint mechanism is designed as a scissor mechanism, overloading can occur, particularly in the area where the first arm is attached to the second arm. This can damage the scissor mechanism when the building closure element is in a closed position. The objective of the present invention is therefore to provide an actuating device that is structurally and functionally designed to at least partially overcome one or more of the disadvantages mentioned with reference to the prior art.

[0008] A further objective of the present invention is to provide an actuating device that is particularly robust and stable, especially when the building closure element is in a closed position. A further objective of the present invention is to provide an actuating device that is compact and structurally simple, so that it can be attached to building closure elements with standard shapes and dimensions.

[0009] The above-mentioned tasks and objectives are at least partially solved by the actuating device according to the invention and a building closure element with one or more of the features listed in the following claims.

[0010] In a first aspect, the present invention relates to an actuating device for a building closure element, comprising: • a first element that can be attached to a first component of the building termination element; • a slider that is slidably coupled to the first element along a longitudinal direction of the first element; • an actuator that can be operated to move the slider along the longitudinal direction between a first position and a third position; • a second element that can be attached to a second component of the building termination element and comprises an auxiliary tenon and preferably a main tenon; • a second arm which is pivotably attached to the glider and to the second element, preferably to the main pin of the second element; • a strike plate that can be securely attached to the first element or component of the building closure element and can be engaged by the auxiliary pin; wherein the strike plate and the second element are designed such that, after the first element and the second element have been attached to the first component or the second component of the building closure element and the strike plate has been attached to the first element or the first component of the building closure element, actuation of the actuator suitable for moving the slider along the longitudinal direction into the third position causes a reciprocal coupling of the auxiliary pin with the strike plate in a locking configuration, and actuation of the actuator suitable for moving the slider along the longitudinal direction out of the third position causes a reciprocal decoupling of the auxiliary pin from the strike plate; in the locking configuration, a mutual interaction between the auxiliary pin and the strike plate counteracts a movement of the auxiliary pin relative to the strike plate in a direction transverse to the longitudinal direction.

[0011] Thanks to the features outlined above, it is possible to obtain a particularly robust and stable actuating device. The interaction between the strike plate and the auxiliary pin improves the strength and stability of the device, as this interaction makes it possible to distribute the load more evenly and reduce concentrated stresses, thus helping to prevent deformation and breakage of the actuating device.

[0012] In its second aspect, the present invention relates to a building closure element comprising the first component, the second component and the actuating device according to the invention, wherein the first element is attached to the first component, the second element is attached to the second component and the strike plate is attached to the first element or to the first component.

[0013] Thanks to the features described above, it is possible to obtain a particularly robust, stable, and vibration-resistant building termination element, especially due to the interaction between the strike plate and the auxiliary pin. This interaction ensures that the connecting device (for example, a hinge) is subjected to a more even load. The actuating device is particularly compact and structurally simple, allowing it to be attached to building termination elements with standard shapes and dimensions.

[0014] In at least one of the aforementioned aspects, the present invention may include at least one or more of the features described below. Depending on the specific requirements of the invention, the first component is a fixed component of the building closure element, and the second component is a movable component of the building closure element, or vice versa. This fixed component may, for example, be a frame, and the movable component may be a sash. In a preferred embodiment, the first component is a fixed component of the building closure element, and the second component is a movable component of the building closure element.In this embodiment, the first element is attached to the fixed component of the building closure element, the second element is attached to the movable component of the building closure element, and the strike plate is attached to either the first element or the fixed component of the building closure element. This design has the advantage that the heavier first element of the actuating device is attached to a fixed component of the building closure element, which facilitates the movement of the movable component and reduces wear on the actuating device and the building closure element.

[0015] According to a preferred embodiment, the first element is attached to an upper edge of the first component and the second element is attached to an upper edge of the second component.

[0016] In an alternative embodiment, the first element is attached to a lateral edge of the first component and the second element is attached to a corresponding lateral edge of the second component.

[0017] In an alternative embodiment, the first component is a movable component of the building closure element, and the second component is a fixed component of the building closure element. In this embodiment, the first element is attached to the movable component of the building closure element, the second element is attached to the fixed component of the building closure element, and the strike plate is attached to either the first element or the movable component of the building closure element. This configuration can be advantageous if, for space reasons, it is not possible to attach the first element to the fixed component of the building closure element.

[0018] The longitudinal direction of the first element preferably coincides with a longitudinal axis of the first element. Preferably, the first and third positions along this longitudinal direction of the first element are consecutive positions, that is, sequential positions along the longitudinal direction.

[0019] Preferably, the second element comprises a main tenon. The main tenon and the secondary tenon are desirablely spaced apart from each other along a longitudinal axis of the second element.

[0020] The strike plate is grippable by the auxiliary pin. When the latter is "gripped" by the strike plate, this means that the auxiliary pin cannot move, except perhaps along a predetermined path. This path can, for example, depend on the design of the strike plate, as described in more detail below. In some alternative embodiments, the auxiliary pin can, for example, be "gripped" by magnets.

[0021] Preferably, an actuation of the actuator, which is suitable to displace the slider along the longitudinal direction of the first element into the third position, causes the second arm to pivot relative to the first element and the second element, resulting in a reciprocal coupling of the auxiliary pin with the strike plate in a locking configuration.

[0022] Preferably, an actuation of the actuator, which is suitable to move the slider along the longitudinal direction of the first element from the third position, causes the second arm to pivot relative to the first element and the second element, resulting in a mutual decoupling of the auxiliary pin from the strike plate.

[0023] Preferably, in the locking configuration, the mutual interaction between the auxiliary pin and the strike plate counteracts a separation of the first element from the second element and, accordingly, of the first component from the second component of the building termination element to which they are attached in the installed state.

[0024] In the locking configuration, the mutual interaction between the auxiliary pin and the strike plate counteracts any movement of the auxiliary pin relative to the strike plate in a direction transverse to the longitudinal direction. This transverse direction is preferably a direction substantially perpendicular to the longitudinal direction of the first element, or in any case, transverse to the latter. This means that, if the actuating device is installed on the building termination element, movement along this transverse direction would result in a separation of the first and second components of the building termination element. In other words, a direction transverse to the longitudinal direction of the first element is understood to be a direction that intersects the latter and forms an angle of at least 10°, and preferably at least 20°, with it.

[0025] The strike plate is preferably designed to: • to pick up the auxiliary pin when the slider moves from the first to the second position, and • to allow the auxiliary pin to slide along the longitudinal direction of the first element as the slider moves between the second and third positions.

[0026] Preferably, the actuating device comprises a joint mechanism that includes the second arm and a first arm that is attached to the first element and to the second arm.

[0027] The second component is advantageously movable between an open position and a closed position relative to the first component by means of an actuating device.

[0028] Preferably, the second component, when moving relative to the first component between the closed and open positions, performs a pivoting movement relative to the first component. Preferably, the second component pivots relative to the first component about a pivot axis. This pivot axis is preferably located at a lower edge of the second component. This is the case, for example, when the building closure element is a tilt-and-turn window or a transom window.

[0029] In alternative embodiments, the pivot axis can be located in a central section of the second component. This is the case, for example, if the building closure element is a pivot window. The building closure element is preferably designed as a window, and even more preferably as a motorized window. In preferred embodiments, the building closure element does not include a handle.

[0030] A second component in the closed position is understood to mean that this second component, in particular its outer frame, abuts the first component of the building closure element. A second component in the open position is understood to mean that this second component, in particular its outer frame, does not abut the first component of the building closure element.

[0031] Preferably, the second component is attached to the first component by a mounting device. The mounting device may include a hinge. The hinge may define the pivot axis about which the second component can pivot around the first component.

[0032] Preferably, the second component is displaced relative to the first component between the open and closed positions by the actuating device. Preferably, the first element of the actuating device is attached to the first component of the building closure element, and the second element of the actuating device is attached to the second component of the building closure element. The displacement of the second element relative to the first element of the actuating device, caused by the movement of the slider, allows the second component, to which the second element is attached, to displace itself relative to the first component of the building closure element.

[0033] The second component is preferably in the open position when the slider is between the first and second positions, and the second component is in the closed position when the slider is between the second and third positions.

[0034] In the embodiment in which the first element of the actuating device is fixedly connected to the first component of the building closure element and the second element of the actuating device is fixedly connected to the second component of the building closure element, it is preferred that when the second component is in the open position, the second element is also in the open position, and when the second component is in the closed position, the second element is also in the closed position.

[0035] It is desirable that the second element be slidably connected to the second component of the building closure element by means of a sliding element. Depending on the embodiment, this sliding element can be contained in the actuating device or integrated into the second component of the building closure element. The sliding element can, for example, be designed as a sliding guide into which the second element is inserted and which is designed to allow the second element to slide, with the guide being mountable on the second component. The sliding element can, for example, include a groove that is formed on the second component, as described below.Preferably, the second element performs a pivoting-sliding movement when attached to the second component: when the second component is in the open position, the second element can pivot together with the second component relative to the first component; when the second component is in the closed position, the second element can be moved relative to both the first component and the second component.

[0036] The auxiliary pin can advantageously slide along the longitudinal direction of the first element by the movement of the slider and the movement of the second element along this longitudinal direction.

[0037] Preferably, the first component comprises a receptacle designed to accommodate the actuating device. This receptacle can advantageously accommodate the device even when the strike plate is in the locked configuration. Preferably, the first and second elements are connected to each other by a hinge mechanism.

[0038] Preferably, the first element comprises a hollow body designed to at least partially contain the slider and the actuator. Preferably, the strike plate is designed to receive the auxiliary pin when the second element moves between the open and closed positions.

[0039] Preferably, the strike plate includes an opening that faces the auxiliary pin and through which the auxiliary pin is received in the strike plate.

[0040] In a preferred embodiment, the strike plate comprises a seat comprising: • an opening through which the auxiliary pin can enter or exit from the seat, and • a gripping section that can be engaged by the auxiliary pin in order to grip the latter with the strike plate.

[0041] The second element is displaceable relative to the first element by means of the second arm attached to the slider, so that, after the first element and the second element are fastened to the first component or to the second component of the building closure element and the strike plate is fastened to the first element or to the first component of the building closure element, the auxiliary pin passes through the opening when the slider transitions between the first and a second position, and the auxiliary pin passes through the gripping section when the slider transitions between the second and third positions in order to grip the strike plate. where the second position is an intermediate position between the first and third positions along the longitudinal direction of the first element.

[0042] In this way, a particularly smooth displacement of the auxiliary pin in the strike plate is achieved, positioning which makes the operating device particularly quiet, and a particularly stable gripping of the auxiliary pin in the strike plate, which makes the operating device robust.

[0043] Preferably, the first, second, and third positions follow one another along the longitudinal direction of the first element.

[0044] Preferably, the strike plate is designed to allow the auxiliary pin to slide along its longitudinal axis when the slider moves between the second and third positions. This facilitates the sliding of the pin because it occurs in the same direction as the actuation of the slider. Preferably, the main pin and the first element are spaced apart by a maximum distance when the slider is in the first position and by a minimum distance when the slider is between the second and third positions. Preferably, the distance between the main pin and the first element can be defined along a straight line connecting the main pin and the longitudinal axis of the first element, and perpendicular to the longitudinal axis of the first element. When the device is in use, the longitudinal axis of the first element and the longitudinal axis of the second element are substantially parallel to each other.In this case, the distance between the first and second elements essentially corresponds to the distance between the longitudinal axis of the first element and the longitudinal axis of the second element, calculated along a straight line perpendicular to these two axes. Preferably, when the slider is in an intermediate position between the first and second positions, the main pivot is located at an intermediate distance from the first element that lies between the maximum and minimum distances.

[0045] Preferably, the second element is designed such that the path traversed by the auxiliary pin is continuous at the opening and at the gripping section, depending on the position of the slider.

[0046] In a preferred embodiment, the strike plate includes a seat. This seat is designed to prevent lateral displacement of the auxiliary pin. This ensures a particularly stable positioning of the auxiliary pin in the strike plate, which makes the actuating device more robust. Preferably, the seat comprises a straight section and a section inclined relative to the straight section, wherein the seat is designed such that the auxiliary pin passes through the inclined section when the slider is positioned from the first position to the second position, and the auxiliary pin passes through the straight section when the slider is between the second and third positions.Thanks to this design, the auxiliary pin initially comes into contact with the inclined section in order to gradually engage with the strike plate, which reduces the stresses and mechanical strain and improves the noise level of the actuating device.

[0047] Preferably, the auxiliary pin passes through the inclined section when the second component is in the open position. Preferably, the auxiliary pin passes through the straight section when the second component is in the closed position. Preferably, the seat of the strike plate includes the opening through which the auxiliary pin is received in the strike plate.

[0048] Preferably, the strike plate seat includes an end stop against which the auxiliary pin engages when the slider is in the third position. This allows the building closure element to be stabilized when the second element is in the closed position.

[0049] Preferably, the straight section extends along the longitudinal direction. According to a preferred embodiment, the strike plate comprises a pair of oppositely positioned bearing areas, such that the seat is arranged between them.

[0050] Thanks to these features, it is possible to achieve a particularly stable and balanced connection between the strike plate and the first component of the building closure element.

[0051] In a preferred embodiment, the second element comprises a longitudinal body including a first and a second end that are opposite to each other, with the main pin being located at the first end and the auxiliary pin being located at the second end, the second arm being pivotably attached to the main pin.

[0052] These features make it possible to obtain a second element with a structure that is particularly suitable for sliding relative to the second element when the latter is in the closed position and is displaced relative to the second component as a result of the movement of the slider along the longitudinal direction.

[0053] Thanks to these features, the main and auxiliary pins are spaced apart, resulting in a second element with a particularly well-balanced structure. Preferably, the longitudinal body of the second element is an extruded part, for example, made of aluminum or PVC. This extruded part can preferably be produced as a single piece using an extrusion process, which can then be cut to a suitable length for attachment to the second component. Preferably, the second component comprises a standard profile, such as the "Camera Europea" standard. This allows the use of standard-sized hardware. Preferably, the extruded longitudinal body of the second element is cut to standard dimensions to allow attachment to the standard profile of the second component.In alternative embodiments, the second component comprises a profile that does not correspond to any standard type, and in this case, the longitudinal body of the second element, which is designed as an extruded part, is cut to length to match the non-standard profile.

[0054] According to a preferred embodiment, the second arm of the actuating device comprises a hooking device designed to detachably connect the main pivot to the second arm. Thanks to the aforementioned features, it is possible to decouple the main pivot and the joint mechanism, making maintenance work particularly easy. Preferably, the hooking device is located at a second end of the second arm.

[0055] Preferably, the engagement device comprises a gripping element that can be detachably connected to the main pin, a locking element, and an elastic element. Preferably, the gripping element is movable between an engagement position and an disengagement position. This design of the engagement device allows for a significant optimization of space requirements and may, if necessary, eliminate the need for a heavier and more space-consuming release device on the actuator.

[0056] When the gripping element is in the engaged position, the locking element held by the elastic element preferably prevents the gripping element from shifting, thus keeping it connected to the main pin. The locking element can preferably be shifted by overcoming the spring force of the elastic element, allowing the gripping element to shift, preferably pivot, from the engaged position to the disengaged position, thereby enabling its separation from the main pin. Any emergency release to separate the gripping element from the main pin can be performed, for example, with a tool, such as a screwdriver, acting on the locking element.

[0057] In a preferred embodiment, the gripping element can be configured as a hook, the elastic element can be configured as a spring, and the locking element can be configured as a plate. Preferably, this plate includes a recess configured to receive a corresponding projection of the gripping element, wherein the plate is displaceable to allow the projection, and thus the gripping element, to be moved between the engaged and disengaged positions.

[0058] In a preferred embodiment, the second component comprises a removable part. When removed, this part provides access to a cavity designed to allow access to the release element, enabling interaction with it, for example, using a tool. Advantageously, this cavity can be covered with the removable part of the second component once the disengagement of the gripping element from the main pin is complete.

[0059] According to a preferred embodiment, the actuating device comprises an additional strike plate that can be firmly attached to the first element or component of the building closure element, and the second element comprises an additional auxiliary pin, wherein the additional strike plate can be grasped by the additional auxiliary pin.

[0060] Thanks to the aforementioned features, it is possible to obtain an even more robust and stable operating device. The interaction between multiple strike plates and their respective auxiliary pins further improves the strength and stability of this device, as this interaction allows for a more even distribution of the load and a reduction in concentrated stresses, thus helping to prevent deformation and breakage of the operating device.

[0061] Preferably, the additional strike plate and the second element are designed such that, after the first element and the second element are attached to the first component and the second component of the building closure element, respectively, and after the additional strike plate is attached to the first element or the first component of the building closure element, actuation of the actuator, which is suitable for moving the slider along the longitudinal direction into the third position, causes a mutual coupling of the additional auxiliary pin with the additional strike plate in a locking configuration, and actuation of the actuator, which is suitable for moving the slider along the longitudinal direction out of the third position, causes a mutual decoupling of the additional auxiliary pin from the additional strike plate;wherein in this locking configuration a mutual interaction between the additional auxiliary pin and the additional strike plate counteracts a movement of the additional auxiliary pin relative to the additional strike plate in a direction transverse to the longitudinal direction.

[0062] Preferably, the additional strike plate is designed as follows: - to accommodate the additional auxiliary pin when the glider moves from the first to the second position, and - to allow the additional auxiliary pin to slide along the longitudinal direction when the glider shifts between the second and third positions.

[0063] Preferably, the locking bolt and the additional locking bolt are spaced apart from each other along a longitudinal axis of the second element. Preferably, the strike plate and the additional strike plate are spaced apart from each other along the longitudinal direction.

[0064] Preferably, the additional strike plate is designed to allow the additional auxiliary pin to slide along its longitudinal axis when the slider moves between the second and third positions. This facilitates the sliding of the pin because it occurs in the same direction as the actuation of the slider. Embodiments are provided in which the actuating device comprises a plurality of additional strike plates spaced apart from one another along its longitudinal axis, and in which the second element comprises a plurality of additional auxiliary pins.

[0065] Preferably, the second element can comprise an additional longitudinal body configured to connect two consecutive tenons. The consecutive tenons can advantageously be two auxiliary tenons or one auxiliary tenon and one main tenon.

[0066] In a preferred embodiment, the joint mechanism is designed as a scissor mechanism comprising a first arm rotatably attached to the first element, and a second arm being attached at its first end to the slider and at its second end to the second element, wherein the first arm is further attached to the second arm, thus forming the scissor mechanism.

[0067] The scissor mechanism has several advantages over other mechanisms: it offers greater stability, which is particularly useful for large-format building closure elements, and allows for an adjustable opening width for controlled ventilation; it increases security by making forced opening from the outside more difficult and reduces the space required inside, as the building closure element opens outwards; it facilitates maintenance and cleaning both inside and out and allows for more efficient natural ventilation even under adverse climatic conditions.

[0068] In alternative embodiments, the joint mechanism can be designed as a parallelogram mechanism or a simple arm mechanism.

[0069] According to a preferred embodiment, the first arm comprises a first arm guide, which includes a straight section and a section inclined relative to the straight section, and the second arm comprises a first arm pivot inserted into the first arm guide, such that the first arm pivot passes through the inclined section when the slider is between the first and second positions, and the first arm pivot passes through the straight section when the slider is between the second and third positions. Thanks to the aforementioned features, a particularly stable scissor mechanism is obtained, which can be moved in a controlled manner.The inclined section allows for a gradual movement of the second arm relative to the first arm as the slider moves between the first and second positions, and the straight section allows the second arm to be moved along the longitudinal direction relative to the first arm as the slider moves between the second and third positions, thus moving the second element along the longitudinal direction. Preferably, the first pin passes through the inclined section when the second component is in the open position. Preferably, the first pin passes through the straight section when the second component is in the closed position.

[0070] According to a preferred embodiment, the first arm comprises a second arm guide which includes a pivot area and a straight section, and the second arm comprises a second arm pin which is inserted into the second arm guide, such that the second arm pin pivots around the pivot area when the slider is between the first and second positions, and the second arm pin passes through the straight section when the slider is between the second and third positions.

[0071] Thanks to the aforementioned features, a scissor mechanism, and thus an actuating device, is obtained that is particularly stable and can be moved in a controllable manner. The pivot point area allows for a gradual pivoting of the second arm relative to the first arm as the slider moves between the first and second positions, and the straight section allows the second arm to be moved longitudinally relative to the first arm as the slider moves between the second and third positions, thereby displacing the second element longitudinally.

[0072] Preferably, the second pin pivots around the pivot point area when the second component is in the open position. Preferably, the second pin passes through the straight section when the second component is in the closed position.

[0073] The presence of both the first and second arm guides and their respective first and second arm pivots allows for a particularly even distribution of the forces exerted on the scissor mechanism. This reduces the stress on each pivot point and minimizes the risk of deformation or damage. Furthermore, the increased precision of the second component's opening and closing action enables smoother and more controlled movement. This extends the service life of the scissor mechanism and improves its overall reliability, making it more suitable for applications requiring frequent opening and closing of the second component.

[0074] According to a preferred embodiment, the actuator comprises an electric motor and a spindle that is driven by the electric motor and engages with a corresponding spindle nut formed on the slider. Thanks to these features, a compact, quiet, highly energy-efficient, and low-backlash actuator can be obtained.

[0075] The actuator is preferably a linear actuator.

[0076] Preferably, a corresponding spindle nut engages with the spindle, which is formed on the aforementioned movable slider or on another component attached to it.

[0077] Optionally, the actuator can include a release device designed to decouple the spindle from the electric motor. The presence of a release device can facilitate the opening and closing of the second component even in the event of a defect in the electric motor or a power failure. In a preferred embodiment, the second element includes a groove designed to receive the second element of the actuating device and to allow the second element to be moved along the groove when the slider moves between the second and third positions.

[0078] Thanks to these features, the movement of the second element relative to the second component is facilitated, so that the auxiliary pin slides smoothly along the longitudinal direction in the strike plate when the slider moves between the second and third positions. The features and advantages of the invention are clarified by the detailed description of a preferred embodiment, which is shown by way of example and without limitation in the accompanying drawings; they show: - Fig. 1 and Fig. 2 the building termination element with the second component in the open position, with a separate or connected hooking device; - Fig. 3 a preferred embodiment of the strike plate; - Fig. 4, Fig. 5 and Fig. 6 the actuating device with the slider in an intermediate position between the first and second positions, in the second or third position; - Fig. 7 and Fig. 8 a detail of the building closure element at the actuating device when the second component is in the opening or closing position; - Fig. 9A and Fig. 9B an embodiment of the actuating device comprising a plurality of strike plates and a plurality of auxiliary pins, wherein the second element is in a closed or an open position; - Fig. 10A and Fig. 10B an embodiment of the hooking device in which the gripping element is in the hooking position or in the unhooking position.

[0079] In the examples in the figures, 100 represents an actuating device and 101 represents a building closure element comprising this actuating device 100, which are designed according to the invention.

[0080] In the examples of Fig. 1 and Fig. Figure 2 shows an embodiment of the building closure element 101, which is designed as a motorized window that does not include a handle. In the Fig. 1 and Fig. In the embodiment shown in Figure 2, the building closure element 101 comprises a first component 1, which is configured as a frame, and a second component 2, which is configured as a sash. The second component 2 is movable relative to the first component 1 between an open position and a closed position by means of the actuating device 100.

[0081] The second component 2 pivots relative to the first component 1 between the closed and open positions about a pivot axis R. This pivot axis R is preferably located at a lower edge 111 of the second component 2. The second component 2 is attached to the first component 1 by a mounting device that includes a pair of hinges 91, which define the pivot axis R about which the second component 2 can pivot around the first component 1. A second component 2 in the closed position is understood to have its outer frame 92 abutting the first component 1 of the building closure element 101. A second component 2 in the open position is understood to have its outer frame 92 not abutting the first component 1 of the building closure element 101, as in the examples of Fig. 1 and Fig. 2 shown.

[0082] The pivoting of the second component 2 relative to the first component 1 between the open and closed positions is effected by the actuating device 100. The first element 11 of the actuating device 100 is attached to the first component 1 of the building closure element 101, and the second element 12 of the actuating device 100 is attached to the second component 2 of the building closure element 101. The displacement of the second element 12 relative to the first element 11, caused by the movement of the slider 3, allows the second component 2 to pivot relative to the first component 1, since the second element 12 is attached to the second component 2.The second component 2 is in the open position when the slider 3 is located between the first position X1 and the second position X2, and the second component 2 is in the closed position when the slider 3 is located between the second position X2 and the third position X3. In other words, when the slider 3 is distal to the strike plate 32, then the second component 2 is in the open position; when the slider 3 is proximal to the strike plate, then the second component 2 is in the closed position.

[0083] The second element 12 is attached to the second component 2 via a sliding element. In the Fig. In the embodiment shown in Figure 2, the sliding element is integrated into the second component 2 and is designed as a groove 79. The groove 79 is configured to receive the second element 12 of the actuating device 100 and to allow the second element 12 to be displaced along the groove 79 when the slider 3 moves between the second position X2 and the third position X3. The first component 1 can include a receptacle 80 configured to receive the actuating device 100. This receptacle 80 can advantageously also receive the device 100 when the second component 2 is in the closed position, as in the example shown in Figure 2. Fig. 8 shown.

[0084] As in the examples of Fig. As can be seen more clearly in Figures 4-6, the actuating device 100 comprises a first element 11, a second element 12, and a joint mechanism 4. The first element 11 includes a slider 3 and an actuator. The slider 3 is displaceable along a longitudinal direction X of the first element 11, and the actuator is configured to actuate the slider 3 along the longitudinal direction X. The second element 12 includes a main pivot 41. The joint mechanism 4 includes a second arm 22, which is pivotably attached to the slider 3 and to the main pivot 41 of the second element 12.

[0085] The first element 11 and the second element 12 are connected to each other by the joint mechanism 4. The joint mechanism 4 is attached to the slider 3 and the main pin 41 and is configured to move the second element 12 relative to the first element 11 by moving the slider 3 along the longitudinal direction X. The slider 3 is displaceable between a first position X1, a second position X2, and a third position X3, with these positions X1, X2, and X3 being successive along the longitudinal direction X. The first element 11 and the main pin 41 of the second element 12 are spaced apart by a maximum distance D1 when the slider 3 is in the first position X1, and by a minimum distance D2 when the slider 3 is between the second position X2 and the third position X3. The longitudinal direction X preferably coincides with a longitudinal axis of the first element 11.

[0086] In the Fig. 1 and Fig. In the two embodiments shown, the first element 11 is attached to an upper edge 113 of the first component 1 and the second element 12 is attached to an upper edge 112 of the second component 2. When the device 100 is in use, the longitudinal axis of the first element 11 and the longitudinal axis G of the second element 12 are substantially parallel to each other.

[0087] In an alternative embodiment not shown, the first element 11 is attached to a lateral edge 115 of the first component 1, and the second element 12 is attached to a corresponding lateral edge 114 of the second component 2. The second element 12 comprises an auxiliary pin 42, which is separate from the main pin 41, and the actuating device 100 comprises a strike plate 32. The strike plate 32 is configured to receive the auxiliary pin 42 when the slider 3 moves from the first position X1 to the second position X2, and to allow the auxiliary pin 42 to slide when the slider 3 moves between the second position X2 and the third position X3. Preferably, the strike plate 32 is configured to allow the auxiliary pin 42 to slide along the longitudinal direction X when the slider 3 moves between the second position X2 and the third position X3, as in the examples of Fig. 5 and Fig. 6 shown.

[0088] Actuation of the actuator, suitable for displacing the slider 3 along the longitudinal direction X into the third position X3, causes a reciprocal coupling of the auxiliary pin 42 with the strike plate 32 in a locking configuration, as in the example of Fig. 6 shown.

[0089] Actuation of the actuator, suitable for displacing the slider 3 along the longitudinal direction X from the third position X3, causes a mutual decoupling of the auxiliary pin 42 from the strike plate 32, as in the example of Fig. 4 shown. If the glider 3 is in an intermediate position Xn between the first X1 and the second position X3, as in the example of Fig. As shown in Figure 4, the main cone 41 is located at an intermediate distance Dn from the first element, which lies between the maximum distance D1 and the minimum distance D2.

[0090] The first element 11 comprises a hollow body 88 designed to at least partially contain the slider 3 and the actuator.

[0091] The strike plate 32 is preferably adjacent to the first element 11, and even more preferably in contact with an end of the body 88 of the first element 11. This makes it possible to optimize the spaces of the building closure element 101.

[0092] The main tenon 41 and / or the auxiliary tenon 42 are / are preferably designed as mushroom-head tenons.

[0093] The strike plate 32 is designed to receive the auxiliary pin 42 when the second component 2 shifts between the open position and the closed position.

[0094] The strike plate 32 includes an opening 60 facing the auxiliary pin 42, through which the auxiliary pin 42 is received in the strike plate 32. The strike plate 32 includes a seat 61 that incorporates the opening 60. This seat 61 is designed to prevent lateral displacement of the auxiliary pin 42. In the embodiment shown in the figures, the seat 61 includes a straight section 61A and a section 61B inclined relative to the straight section 61A. It is designed such that the auxiliary pin 42 passes through the inclined section 61B when the slider 3 is located between the first position X1 and the second position X2, and the auxiliary pin 42 passes through the straight section 61A when the slider 3 is located between the second position X2 and the third position X3. The straight section 61A extends along the longitudinal direction X.

[0095] The auxiliary pin 42 passes through the inclined section 61B when the second component 2 is in the open position, and the straight section 61A when the second component 2 is in the closed position.

[0096] The seat 61 of the strike plate 32 includes an end stop 63 against which the auxiliary pin 42 comes to rest when the slider 3 is in the third position X3. Preferably, the auxiliary pin 42 abuts a stop edge 62 of the seat 61 of the strike plate 32 when the slider 3 moves between the first position X1 and the second position X2.

[0097] The strike plate 32 can include a pair of support areas 64 that are opposite each other, so that the seat 61 is arranged between them.

[0098] The two support areas 64 are designed to connect the strike plate 32 to the first component 1. Preferably, each support area 64 includes a hole for attachment to the first component 1 by means of a threaded connection. Attachment is advantageously made to the receptacle 80 of the first component 1, thus optimizing space requirements. Preferably, the strike plate 32 is designed such that the support areas 64 are located on substantially coplanar walls and that the seat 61 is located on a wall that is recessed relative to the walls. In a preferred embodiment, the second element 12 comprises a longitudinal body 44 that includes a first end 45 and a second end 46, which are opposite to each other, with the main pin 41 located at the first end 45 and the auxiliary pin 42 being located at the second end 46.

[0099] In the Fig. 9A and Fig. In the embodiment shown in Figure 9B, the actuating device 100 comprises two additional strike plates 32 and the second element 12 comprises two additional auxiliary pins 42. Each additional strike plate 32 is configured to receive the respective additional auxiliary pin 41 when the slider 3 moves from the first X1 to the second position X2, and to allow the respective additional auxiliary pin 41 to slide along the longitudinal direction X when the slider 3 moves between the second X2 and the third position X3.

[0100] The locking pins 42 are spaced apart from each other along the longitudinal axis G of the second element 12, and the locking plates 32 are spaced apart from each other along the longitudinal direction X of the first element 11.

[0101] The second element 12 comprises two additional longitudinal bodies 44, which are designed to connect two consecutive tenons. In the examples of Fig. 9A and Fig. 9B connects the left additional longitudinal body 44 auxiliary pin 42 and main pin 41 and the right additional longitudinal body 44 two auxiliary pins 42.

[0102] In the illustrated embodiment, the joint mechanism 4 is designed as a scissor mechanism comprising a first arm 21 rotatably attached to the first element 11, and a second arm 22 which is attached at its first end 22A to the slider 3 and at its second end 22B to the main pin 41, wherein the first arm 21 is further attached to the second arm 22, so that the scissor mechanism 2 is formed.

[0103] As in the example of Fig. As can be seen in Figure 4, the first arm 21 comprises a first arm guide 81, which includes a straight section 81A and an inclined section 81B relative to the straight section 81A, and the second arm 22 comprises a first arm pin 91, which is inserted into the first arm guide 81, such that the first arm pin 91 passes through the inclined section 81B when the glider 3 is between the first X1 and the second position X2, and the first arm pin 91 passes through the straight section 81A when the glider 3 is between the second X2 and the third position X3.

[0104] Preferably, the first arm pivot 91 passes through the inclined section 81B of the first arm guide 81 when the second component 2 is in the open position, and through the straight section 81A of the first arm guide 81 when the second component 2 is in the closed position.

[0105] As in the example of Fig. As can be seen in Figure 4, the first arm 21 includes a second arm guide 82, which has a pivot point area 82B (in the example of Fig. 8 better to see) and includes a straight section 82A, and the second arm 22 includes a second arm pivot 92 which is inserted into the second arm guide 82, so that the second arm pivot 92 pivots around the pivot area 82B when the glider 3 is between the first X1 and the second position X2, and the second arm pivot 92 passes through the straight section 82A when the glider 3 is between the second X2 and the third position X3.

[0106] The second arm pivot 92 preferably pivots about the pivot point area 82B of the second arm guide 82 when the second component 2 is in the open position, and passes through the straight section 82A of the second arm guide 82 when the second component 2 is in the closed position.

[0107] The straight section 81A of the first arm guide 81 and the straight section 82A of the second arm guide 82 advantageously align with the longitudinal direction X when the distance between the first element 11 and the main pin 41 is equal to the minimum distance D2, i.e., when the slider 3 is located between the second X2 and the third position X3. This facilitates the sliding of the first arm pin 91 in the first arm guide 81 and the sliding of the second arm pin 92 in the second arm guide 82.

[0108] Preferably, the first arm 21 comprises a first end 21A and a second end 21B, which are opposite to each other. The first arm 21 can be attached to the first element 11 at its first end 21A. The first guide 81 and the second guide 82 can be located at the second end 21B of the first arm 21. The first pin 91 and the second pivot 92 can be located in an intermediate section 22C of the second arm 22, this intermediate section 22C being arranged between the first end 22A and the second end 22B of the second arm 22. The joint mechanism 4 can include a hook 40 configured to detachably connect the main pivot 41 to the joint mechanism 4.

[0109] In the illustrated embodiment, the hooking device 40 is located at the second end 22B of the second arm 22. In the examples of Fig. 1 and Fig. 10B the hooking device 40 can be identified as separate from the main pin 41, for example to carry out maintenance work.

[0110] In the Fig. 10A and Fig. In the embodiment shown in Figure 10B, the hooking device 40 comprises a gripping element 71, which is detachably connectable to the main pin 41, a locking element 72, and an elastic element 73. The gripping element 71 is located between a hooking position, which in the example of Fig. 10A is shown, and a disengagement position, which in the example of Fig. As shown in Figure 10B, the gripping element 71 is relocatable. When the gripping element 71 is in the engaged position, the locking element 72, held by the elastic element 73, prevents the gripping element 71 from pivoting, thus keeping it connected to the main pin 41. The locking element 72 can be relocated by overcoming the spring force of the elastic element 73, allowing the gripping element 71 to pivot from the engaged position to the disengaged position and thus enabling the gripping element 71 to be separated from the main pin 41.

[0111] In the Fig. 10A and Fig.In the embodiments shown in Figure 10B, the gripping element 71 is designed as a hook which is pivotable about a pivot point 76, the elastic element 73 is designed as a spring and the locking element 72 is designed as a plate which includes recesses 74 which are designed to receive corresponding projections 75 of the gripping element 71, wherein this plate can be moved so that the displacement of the projections 75 and thus of the gripping element 71 between the hooking position and the unhooking position is made possible.
