Description

DEVICE FOR CLOSING DOORS AND/OR WINDOWS FIELD OF APPLICATION OF THE INVENTION The present invention concerns a closing/locking device for doors and/or windows. More specifically, it concerns a closing/locking device for doors and/or windows in which there are no parts exposed from the door and/or window and/or jamb when the door and/or window is open.

STATE OF THE ART

Closing/locking devices for doors and/or windows are known, for example locks with latches. These devices are often configured in such a way that, when the door and/or window is open, part of the latch protrudes from the door and/or window or from the jamb. This configuration is aesthetically unpleasant and, in some cases, undesirable from the mechanical point of view since the protruding element can hit other elements in the vicinity or users of the door and/or window. Moreover, the known systems do not allow for simple and automatic adjustment of any play between the male and female locking elements.

In addition, the known systems require some type of actuation by the user to move the male locking element into the female locking element and/or some type of actuation by the user to lock the device. On the market there are no devices which, once the door and/or window has been closed, ensure that it automatically remains in the closed/locked position without an actuating operation by the user, such as turning a key, or without an electromechanical actuator.

SUMMARY OF THE INVENTION

Thus, the invention is generically related to a closing/locking device in which the male element is located inside a first part and is extracted automatically only in proximity to a female element, for example by means of magnetic attraction.

In particular, an embodiment may refer to a device for closing/locking a door and/or window with respect to a jamb, comprising a first part mountable on one between the door and/or window and the jamb, a second part mountable on the other between the door and/or window and the jamb, wherein the first part comprises a male locking element movable with respect to the first part, wherein the second part comprises a female locking element and a magnet, wherein the closing/locking device is configured in such a way that the male locking element is attracted by the magnet towards the second part.

In some embodiments, the first part may comprise holding means configured to prevent the return of the male locking element into the first part following the extraction of the male locking element from the first part.

In some embodiments, the holding means may comprise

- an element with variable cross section,

- a movable element positioned at least partially within the element with variable cross section,

- one or more interference elements positioned between the element with variable cross section and the movable element, and

- a retaining element configured in such a way as to retain the one or more interference elements.

In some embodiments, the male locking element can feature a front end with a substantially convex shape in the direction of the second part.

In some embodiments, when the door and/or window is closed, the magnet can be positioned substantially opposite the male locking element with respect to the female locking element.

In some embodiments, the second part may comprise a frame and the female locking element can be made as a cavity in the frame.

In some embodiments, the width of the cross section of the cavity may decrease as the distance from the first part increases.

In some embodiments, the cavity may have a substantially V-shaped cross section.

In some embodiments, the second part may comprise one or more dampening elements configured to dampen the entry of the male locking element into the cavity.

In some embodiments, the frame may comprise one or more housings, respectively for the one or more dampening elements.

In some embodiments, the first part may comprise release means configured to act on the retaining element in such a way as to allow the male locking element to move back into the first part.

In some embodiments, the release means can be configured to push the retaining element towards the second part.

In some embodiments, the retaining element may comprise a thrust surface comprising at least one area with a substantially concave shape, the release means may comprise a conversion element and a roller pin, the roller pin may be at least partially contained within the area with a substantially concave shaped, the conversion element and the roller pin may be configured in such a way that a movement of the conversion element in a direction substantially perpendicular to the direction of movement of the male locking element causes a movement of the roller pin such that the roller pin is pushed at least partially outside of the area with a substantially concave shape causing a movement of the thrust surface towards the second part.

In some embodiments, the closing/locking device may also comprise at least one handle connected to the release means.

In some embodiments, the closing/locking device may also comprise an elastic element configured in such a way as to arrange the release means in a position in which the release means do not exert a releasing action.

In some embodiments, the first part may furthermore comprise at least one sliding element integrally connected to the male locking element, and at least one return element configured to act on the at least one sliding element in such a way that, in the absence of other forces acting on the male locking element, a movement of the male locking element is obtained, such that the male locking element is retracted into the first part.

In some embodiments, the release means may comprise an interference element, and the first part may furthermore comprise a locking element configured so that it has a first position in which the locking element interferes with the interference element and a second position in which the locking element does not interfere with the interference element.

DESCRIPTION OF PREFERRED EMBODIMENTS

In the following detailed description, various embodiments will be described with reference to the drawings. However, it is clear that the present invention is not limited to the embodiments illustrated and/or described herein. In particular, it is clear that different characteristics of different embodiments can be combined with one another to obtain further embodiments. It is also clear that not all the features of a single embodiment are to be considered necessary for the implementation of that embodiment. In particular, in some cases certain features may be described only to clarify the specific operation of the described embodiment even if they are not strictly necessary for the implementation of the invention. Furthermore, it is possible to combine individual characteristics of a first and of a second embodiment in such a way as to obtain a third embodiment of the invention with no need to necessarily include all the other characteristics of the first and of the second embodiment.

Generally speaking, the invention concerns a closing/locking device for doors and/or windows I which makes it possible to eliminate the presence of parts protruding from the door and/or window when this is in an open position, as opposed to classical solutions in which the latch is generally exposed on the outside of the door and/or window while it is being opened.

The invention is particularly advantageous when used with doors and/or windows installed in a hinged configuration. As shown, for example, in Figure 1, the door and/or window I is closed on a jamb S by rotating it in the direction indicated by the arrow, on hinges not illustrated herein.

The closing/locking device 1000 can advantageously be used with a door and/or window I of this type and generally comprises a first part 1100, mountable on one between the door and/or window I and the jamb S, and a second part 1200, mountable on the other between the door and/or window I and the jamb S. In the configuration shown in Figure 1, the first part 1100 is mounted on the door and/or window I, while the second part 1200 is mounted on the jamb S. It is clear, however, that the installation can be reversed.

As can be seen in Figure 2, in general, the first part 1100 comprises a male locking element 2110 which is movable with respect to the first part 1100. The function of the male locking element 2110 is conceptually similar to that of a latch. More specifically, as is evident from the following description, the male locking element 2110 can be moved with respect to the first part 1100 so that it reaches a position of interference with a respective female locking element of the second part 1200, preventing the opening of the door and/or window I.

In general, the second part 1200 thus comprises a female locking element and a magnet 3220, which are described in greater detail below.

The closing/locking device 1000 can thus be configured in such a way that the male locking element 2110 is attracted by the magnet 3220 towards the second part 1200. This configuration advantageously allows the male locking element 2110 to be automatically extracted from the first part 1100 at the moment when the door and/or window I is being closed and therefore is near the jamb S. In the remaining positions of the door and/or window I, as is more evident in the following description, the male locking element 2110, not being sufficiently attracted by the magnet 3220, may remain in a more internal position in the first part 1100 without protruding from the door and/or window I.

Preferably, in some embodiments, the male locking element 2110 can be attracted by the magnet 3220 towards the second part 1200 with a force that is sufficient to extract the male locking element 2110 from the first part 1100 only in an area in proximity to the closing position of the door and/or window I on the jamb S. In some embodiments, this area in proximity to the closing position may preferably correspond to an opening of the door and/or window I of less than 10° with respect to the jamb S, measured with the centre in the hinges of the door and/or window I, even more preferably to an opening of less than 5°.

It is therefore evident that the invention makes it possible to obtain a door and/or window I that when open has no protruding elements, and to automatically extract the male element 2110 when the door and/or window I is being closed thanks to the presence of the magnet 3220 in the second part 1200. It will be clear to the expert in the art that this approach can be implemented through a plurality of mechanically different solutions. Some particularly advantageous embodiments of the invention are described here below, in such a way as to illustrate how this functional approach can be implemented. It is evident, however, that the invention is not limited to the embodiments specifically described herein and that alternative embodiments from a mechanical point of view can lead to the same functional approach as described above.

In some embodiments, the force of the magnet 3220 can be configured to be sufficient to maintain the male locking element 2110 in the extracted position while the door and/or window I is being closed.

In some embodiments, in addition to the force exerted by the magnet 3220, it is advantageous to keep the male locking element 2110 in the extracted position with respect to the first part 1100, so as to ensure that the door and/or window I is closed/locked more securely.

In these embodiments, as can be seen, for example, in Figure 2, the first part

2100 may comprise holding means 2120 configured so as to prevent the male locking element 2110 from moving back into the first part 2100 after the extraction of the male locking element 2110 from the first part 2100.

In general, the holding means 2120 may be configured so as to allow the extraction of the male locking element 2110 from the first part 2100 and prevent the male locking element 2110 from moving back into the first part 2100 in the absence of an appropriate release operation. It will be evident to those skilled in the art that this behaviour can be obtained through various mechanical solutions, for example by means of a ratchet structure, or other solutions.

Figure 2 shows a possible implementation of this functional concept, without necessarily limiting the invention to the specifically illustrated embodiment.

In particular, in the embodiment illustrated in Figure 2, the holding means 2120 comprise an element with variable cross section 2122, a movable element 2121 positioned at least partially within the element with variable cross section 2122, one or more interference elements 2125 positioned between the element with variable cross section 2122 and the movable element 2121, and a retaining element 2124 configured to retain the one or more interference elements.

In greater detail, in some embodiments the movable element 2121 may be a mechanical element in a generically elongated shape, integrally connected to the male locking element 2110. Preferably, the movable element 2121 has a shape that is generically elongated along a longitudinal axis substantially perpendicular to a main direction of extension of the male locking element 2110. In Figure 2, the movable element 2121 has a substantially circular cross section along a plane that is perpendicular to its longitudinal axis. The invention, however, is not limited to this configuration, other shapes of the cross section are possible as will be clear to the person skilled in the art.

In some embodiments, the element with variable cross section 2122 has a cavity with variable cross section. In particular, the cross section can be defined as the cross section of the cavity along a plane that is perpendicular to the longitudinal axis of the movable element 2121. Preferably, said cross section measured with the element with variable cross section 2122 in a first position has a larger surface area than said cross section measured with the element with variable cross section 2122 in a second position. Specifically, the first position is preferably closer to the male locking element 210 than the second position. In some embodiments, the cross section of the element with variable cross section 2122 is preferably reduced gradually between the first position and the second position. Thanks to this configuration, by positioning the interference elements 2125 inside the element with variable cross section 2122, between the inner surface of the element with variable cross section 2122 and the outer surface of the movable element 2121, it is possible to create an interference that prevents the movable element 2121 from moving in the direction away from the second part 1200, that is, in the negative X direction with reference to the figures.

In a preferred embodiment of the invention, the interference elements 2125 may be constituted by small spheres; it will, however, be clear that the invention is not limited to this embodiment and that alternative elements, for example rollers, may be used.

In the embodiment illustrated in Figure 2, the interference elements 2125 are retained by a retaining element 2124. In the embodiment illustrated, the retaining element 2124 has a substantially tubular shape with an outer surface positioned at least partially inside the cavity of the element with variable cross section 2122 and an inner tubular area within which the movable element 2121 can be at least partially positioned. Thanks to this configuration, the retaining element 2124 advantageously allows the interference elements 2125 to be maintained in a predetermined position. Furthermore, as is evident from the following description, the retaining element 2124 can advantageously be used to release the holding means 2120.

In the embodiment illustrated, the holding means 2120 may further comprise a thrust element 2123, for example a spring, respectively positioned between the element with variable cross section element 2122 and the retaining element 2124, in such a way as to provide a force that tends to move these two elements away from each other. In this manner, as will be evident to those skilled in the art, the holding means 2120 tend to position the interference element 2125 in a position of interference of the movement of the movable element 2121 with respect to the first part 2100. This makes it possible to ensure that any movement of the movable element 2121 in the negative X direction is prevented. It is evident that alternative forms of thrust element 2123 can be implemented, for example it can be constituted by a return spring, or a magnet, acting on the retaining element 2124 in such a way as to provide a force acting on it in a negative X direction. Furthermore, in the illustrated embodiment, the first part 2100 comprises a frame which is schematically represented by two components 2130A and 2130B and supports at least the holding means 2120. Figures from 6A to 6C schematically illustrate a possible mode of operation of the holding means 2120.

In particular, in Figure 6A the closing/locking device is in an open position. In this position, the distance between a contact area of the thrust element 2123 with the element with variable cross section 2122 and a contact area of the thrust element 2123 with the retaining element 2124 is indicated by D1A. Analogously, a distance between the end of the element with variable cross section 2122 and the male locking element 2110 is indicated by D2A.

Figure 6B schematically shows a closed position of the closing/locking device. As schematically shown by the arrow, in the closed position the male locking element 2110 has moved in the positive X direction in such a way as to engage with the female locking element, which is not shown. This movement increases the distance D2A, as indicated by the distance D2B. The position of the male locking element 2110 inside the female locking element ensures that the door and/or window I can be closed on the jamb S.

Figure 6C schematically illustrates the operation of releasing the latch element. In particular, as schematically illustrated by the arrow acting on the retaining element 2124, the retaining element 2124 can be moved in the positive X direction, that is, in the direction of the element with variable cross section 2122, so as to reduce the distance D1A until obtaining the distance DIB. This movement causes the corresponding movement of the interference elements 2125 with respect to the element with variable cross section 2122. The interference of the interference elements on the movable element 2121 is thus eliminated, allowing the latter to move with respect to the element with variable cross section 2122. This freedom of movement therefore allows the male locking element 2110, mounted on the movable element 2121, to move in the negative X direction, that is, towards the first part 2100, as schematically indicated by the arrow acting on the male locking element 2110. The movement of the male locking element 2110 in the negative X direction can be caused by various factors, which are described in detail below.

It is therefore apparent that, thanks to the presence of the thrust element 2123, in the absence of a force acting on the retaining element 2124 in the direction substantially indicated by the arrow schematically shown in the figure, the closing/locking device remains in a locked position. On the contrary, when a force is exerted on the retaining element 2124, it is possible to release the closing/locking device as described above. When this force is not applied any longer, the retaining element 2124 can return to the position shown in Figure 6 A, thus ensuring that the device will be locked the next time the door and/or window is closed/locked .

In preferred embodiments, as can be seen in Figure 2, the male locking element

2110 can have a front end 2111 having a substantially convex shape in the direction of the second part 1200. In the illustrated embodiment, the front end

2111 has a substantially rounded shape, but this form is not limiting and alternative forms are possible, for example with a substantially triangular cross section.

As is more evident from the following description, in particular with reference to Figure 4C, the substantially convex shape of the front end 2111 advantageously allows the male locking element 2110 to be gradually pushed into the first part 1100 when the door and/or window I is being opened, thanks to the mechanical interference between the substantially convex shape of the front end 2111 and the shape of a cavity 3232 that is described in greater detail below. However, it is apparent that the invention is not limited to the presence of a substantially convex shape for the front end 2111.

Figure 3A shows a schematic exploded view of a second part 3200. In this embodiment, as can be seen, when the door and/or window I is in the closed position, the magnet 3220 is positioned substantially opposite the male locking element 2110 with respect to the female locking element 3210. Thanks to this configuration, the magnet 3220 can therefore attract the male locking element 2110 towards the female locking element 3210, that is, in the positive X direction.

In preferred embodiments, the second part 3200 comprises a frame 3230. The frame 3230 can be configured in such a way that the female locking element 3210 is constituted by a cavity 3232 obtained in the frame 3230. Preferably, furthermore, the frame 3230 may comprise a seat 3231 for the magnet 3220, in a position substantially opposite the cavity 3232.

Preferably, the width of the cross section of the cavity 3232 decreases as the distance from the first part 1100 increases. In greater detail, the cross section, as can be seen in Figure 3B, can be considered along a plane XZ perpendicular to a direction Y of greatest longitudinal extension of the female locking element

3210. The width of the cross section, thus measured in direction Z, decreases gradually as the distance from the first part 1100 increases or, in other words, as the distance from the magnet 3220 decreases. Thanks to this shape, it is advantageously possible to gradually push the male locking element 2110 out of the cavity 3232. In particular, as is more evident from Figure 4C, a movement in a direction substantially parallel to Z, caused by the rotation of the door and/or window I on its hinges, causes the male locking element 2110 to be pushed in a direction substantially parallel to X due to the substantially convex shape of the cavity 3232, so that the male locking element 2110 is moved out of the female locking element 3210.

In some embodiments, the cavity 3232 has a substantially V-shaped cross section. Preferably, the direction of an axis of symmetry of the “V” shape substantially corresponds to the direction of longitudinal extension of the movable element 2121 when the closing/locking device is in the closed position. Advantageously, this shape makes it possible to eliminate any play between the male locking element 2110 and the female locking element 3210.

Figure 3 A shows also connection elements 3240, for example screws, configured to connect the frame 3230 to the jamb S. It is clear, however, that alternative solutions for the connection elements 3240 and/or for the connection of the frame 3230 to the jamb S can be implemented.

Figures 4A-4C schematically illustrate a possible alternative for the second part 4200. In particular, the second part 4200 differs from the second part 3200 in that it is provided with one or more dampening elements 4250 configured to dampen the entry of the male locking element 2110 into the cavity 3232. Preferably, the frame 4230 comprises one or more housings 4232 for the one or more dampening elements 4250, respectively.

In the embodiment illustrated in Figure 4A, the dampening elements 4250 can be constituted, for example, by rings made of a substantially elastic material, which are inserted into housings 4232 substantially made as grooves in the frame 4230.

As can be seen in Figure 4C, the rings keep a substantially circular shape in the absence of the male locking element 2110. As the male locking element 2110 approaches the second part 4200, the attraction exerted by the magnet 3220 on the male locking element 2110 causes the male locking element 2110 to enter the cavity 3232, thereby impacting the rings and deforming them accordingly. The presence of the rings as dampening elements 4250 makes it possible to control the entry of the male locking element 2110 into the cavity 3232 and to avoid a

- it - general noisiness of the device. Furthermore, the use of the dampening elements 4250 provides a closed configuration of the device, in which the dampening element 4250 is at least partially positioned between the male locking element 2110 and the female locking element 3210, thereby ensuring that any play between the male locking element 2110 and the female locking element 3220 is compensated for by the elastic nature of the dampening element 4250. Advantageously, therefore, this configuration also makes it possible to ensure that the closed/locked position of the closing/locking device is substantially stable.

Figures 5A and 5B schematically illustrate an alternative embodiment for the dampening elements. In particular, the dampening elements 5250 are constituted by tabs elastically mounted in the cavity 3232, preferably with one end of the tabs 5250 connected to the frame 5230 in an area of the cavity 3232 close to its end towards the first part 1100. In this manner, as will be clear to the person skilled in the art, the entry of the male locking element 2110 into the cavity 3232 can cause the tabs 5250 to flex, achieving the same dampening and play compensation effect described above. Clearly, the dampening elements 5250 can be constructed independently of the frame 5230 and mounted on it, or they can be made from the material of the frame itself.

In the preceding description, the operation of releasing the closing/locking device was schematically illustrated as resulting from the application of a force which causes the retaining element 2124 to move in the positive X direction, that is, in the direction of the element with variable cross section 2122. It is clear that various mechanical solutions can be implemented to obtain this type of force acting on the retaining element 2124 and thus the release of the closing/locking device and the consequent opening of the door and/or window I. Figure 7 illustrates a possible specific implementation which makes it possible to obtain this type of movement. It is clear, however, that the invention is not limited to the configuration shown in Figure 7.

In general, the first part 7100 can thus comprise also release means 7140 configured to act on the retaining element 7124 in such a way as to allow the male locking element 2110 to return into the first part 7100. In particular, the release means 7140 can be configured to push the retaining element 7124 towards the second part 1200, that is, in the positive X direction or, in other words, in the direction of the element with variable cross section 2122. More specifically, as can be seen in Figure 7, the retaining element 7124 may comprise a thrust surface 7125 comprising at least one area in a substantially concave shape. The substantially concave shape of the thrust surface 7125 can also be seen in Figures 8 A and 8B .

The release means 7140 can comprise also a conversion element 7141 and a roller pin 7142, wherein the roller pin 7142 can be at least partially contained in the area with a substantially concave shape. Preferably, the roller pin 7142 has a substantially convex shape with a cross section comparable to the concave cross section of the thrust surface 7125 in size. In other words, it is possible to at least partially insert the roller pin 7142 in the concave section of the thrust surface 7125, as particularly illustrated in Figure 8 A.

The conversion element 7141 and the roller pin 7142 are thus configured in such a way that a movement of the conversion element 7141 in a direction substantially perpendicular to a direction of movement of the male locking element 2110 causes a movement of the roller pin 7142 such that the roller pin 7142 is pushed at least partially out of the area in a substantially concave shape, causing a movement of the thrust surface 7125 towards the second part 1200. This behaviour is particularly evident when comparing Figures 8 A and 8B.

The at least partial exit of the roller pin 7142 from the thrust surface 7125 causes a movement of the thrust surface in the positive X direction, and thus a consequent movement of the retaining element 7124, which results in the release operation described above.

It is clear that the specific embodiment described is only one of the possible embodiments and that, for example, the roller pin 7142, instead of being a separate element, can be obtained by means of an area with a substantially similar form, created in the conversion element 7141.

As shown in Figure 7, the closing/locking device also includes at least one handle 7150 connected to the release means 7140.

This configuration is particularly advantageous since it is possible to push the handle 7150 in direction Z causing a corresponding movement of the release means 7140 and thus carrying out the release operation. This type of movement is particularly advantageous since pushing the handle 7150 results not only in the release of the closing/locking device but also in the movement of the door and/or window I. It is therefore evident that with a single movement it is possible to release and open the door and/or window I. In general, therefore, the action of a force in direction Z, that is, in a direction substantially perpendicular to the plane of the door and/or window I, can be converted by the conversion element 7141 into a force in direction X, that is, substantially parallel to the longitudinal extension axis of the movable element 2121, resulting in the previously described release operation. It is evident that the conversion from a force applied in direction Z into a resulting force in direction X can be achieved with different mechanical configurations, for example with various types of lever mechanisms, different from the release means 7140 described herein. It is therefore apparent that release means 7140 functionally configured to convert a force acting in direction Z into a force acting in direction X can be used in alternative embodiments of the invention, independently of their mechanical construction.

Furthermore, although the action of the release means 7140 described above is particularly advantageous, given that a single movement makes it possible to release and open the door and/or window I, the invention is not limited to this embodiment. In alternative embodiments, it is possible to act on the handle 7150 through a rotary movement, and to configure the release means 7140 so that the rotation of the handle 7150 results in a rotation of the release means 7140 and the rotation of the latter results in a force in direction X acting on the retaining element 7124. By way of example, it is possible to configure the conversion element 7141 as a cam acting on the surface 7125.

In preferred embodiments, as schematically illustrated in Figure 7, the closing/locking device may furthermore comprise an elastic element 7160, for example a spring in a substantially laminar shape, mounted on the frame of the first part 7100. The conversion element 7141 may also advantageously be provided with a seat for the elastic element 7160. This configuration advantageously allows the conversion element 7141 to be returned to a position where the roller pin is contained to the maximum extent in the area having a substantially concave shape. Clearly, alternative mechanical embodiments can achieve the same functional effect. The invention can thus be implemented by means of any elastic element 7160 configured to arrange the release means 7140 in a position in which the release means 7140 do not exert a release action on the holding means.

In the embodiment illustrated in Figure 7, the device is provided with two handles 7150 which can thus be respectively mounted internally and externally with respect to the door and/or window I. It is evident from the description provided above that the advantageous conversion of the pushing or pulling action exerted on the handle will result in a simultaneous release and opening of the door and/or window for any of the handles 7150, regardless of their position inside or outside the door and/or window I, respectively. The invention, however, is not limited to this embodiment, and embodiments comprising a single internal or external handle will also be possible.

In the above description, the return of the male locking element 2110 into the first part 2100 was described as resulting from the interference action of the male locking element with the walls of the cavity 3232 of the female locking element 3210.

Alternatively, or additionally, as illustrated in Figures 9 A and 9B, the first part 9100 may furthermore comprise at least one sliding element 9170 integrally connected to the male locking element 2110, and at least one return element 9180 configured to act on the at least one sliding element 9170 in such a way that, in the absence of other forces acting on the male locking element 2110, the male locking element 2110 is moved in such a manner as to retract the male locking element 2110 into the first part 9100.

More specifically, in the illustrated embodiment there are two sliding elements 9170 but the invention is not limited this specific number. Furthermore, although the return element 9180 is illustrated as a spring compressing one of the sliding elements 9170, the invention is not limited this embodiment. For example, the return element 9180 can be constituted by a spring exerting a traction action on the sliding element 9170, or a foil, or a magnet, or an elastic band, etc.

It is therefore apparent that, in the absence of other forces exerted on the male locking element 2110, the action of the return element 9180 on the sliding element 9170 will cause a movement of the male locking element 2110 in the direction of return into the first part 9100, thereby ensuring that the male locking element 2110 does not remain externally exposed on the first part 9100 when the door and/or window I is open.

In some embodiments of the invention, as for example shown in Figures 10A-

10C, the release means 10140 may comprise an interference element 10144, and the first part 10100 may comprise also a locking element 10191 configured so that it has a first position in which the locking element 10191 interferes with the interference element 10144 and a second position in which the locking element 10191 does not interfere with the interference element 10144.

In the illustrated embodiment, a locking control element 10190, for example a knob, can be connected to the outside of the first part 10100 and act on the locking element 10191 inside the first part 10100. In this manner, from the side of the first part where the locking control element 10190 is provided, it is possible to check whether the device can be released or not. In particular, in the position illustrated in Figures 10A and 10B, the position of the locking element 10191 prevents the movement of the interference element 10144 and consequently of the conversion element 7141 in direction Z, making it impossible to release the device and thus guaranteeing that the door and/or window I is closed securely.

Furthermore, in some embodiments, on the opposite side with respect to the knob the element 10190 can have such a shape that the device can be released in case of emergency. For example, on the side opposite the knob, the element 10190 may have a shape into which a tool in a complementary shape can be inserted, through a special hole in the part 2130B of the frame. Thus, this simple hole, in the absence of the release tool, prevents the release of the device, which therefore cannot be easily opened from side 2130B. On the other hand, the possibility to release the device from side 2130B with an appropriate tool, for example a screwdriver or another tool having a specially shaped head, advantageously makes it possible to guarantee the possibility to release the device in case of emergency. In Figure 10 A, for example, the element 10190 is configured with a recess for inserting a flat screwdriver in the side opposite the knob.

Although some embodiments already allow the closing/locking device to be locked in the closed position, it is evident that it will also be possible to install a latch, so that the device can be locked with a key. An example is illustrated in Figure 11, where it can be seen that the first part can furthermore comprise a latch 11300, which can be configured in any known way. In this case, the second part 11200 can furthermore comprise a locking element 11211 for the latch, which can be made in any known manner, too.

Figure 12A shows a schematic view of an assembled closing/locking device 12000 comprising one or more additional closing/locking elements 12300. The additional closing/locking elements 12300 provide additional closing/locking points with respect to the single closing/locking point of the previously described closing/locking devices. The additional closing/locking elements 12300 are connected to the first part 12100 via an actuating element 12400 configured to propagate a release movement from the first part 12100 to the one or more closing/locking elements 12300. In the figure, the actuating element is constituted by a rod but it is clear that alternative embodiments, for example by means of a cable, are possible.

Each of the additional closing/locking elements 12300 conceptually operates similarly to the previously described closing/locking devices and comprises in particular a first part 12310 and a second part, not illustrated. The second part may be constituted by any of the previously described second parts.

The first part 12310 comprises a male locking element 12311 similar to the one described above and connected to holding elements 12312 similar to those described above. As the male locking element 12311 approaches the second part, not illustrated, it moves out of the first part and remains locked in the second part, as previously described. From this position, the release operation can be carried out, analogously to what has been described above, through a movement of the retaining element 12313 to the right, as can be seen in Figure 12A.

In particular, as can be seen in Figure 12B, a movement of the retaining element 2124, or of the release means, causes, via a conversion element 12410, a movement of the actuating element 12400. The movement of the actuating element 12400 in turn causes, via a conversion element 12420, a movement of the retaining element 12313. Preferably, the movement of the retaining elements 2124 and 12313 is in the same direction. Preferably, the movement of the actuating element is in a direction substantially perpendicular to the direction of movement of the retaining elements. The conversion elements 12410, 12420 can thus be made with any mechanical configuration allowing for this type of conversion, for example with cams.

For example, as can be seen in Figure 12C, the conversion element 12420 may comprise a roller pin 12421 connected to the actuating element 12400. The retaining element 12313 may comprise a concave seat for the roller pin 12421. A movement of the actuating element 12400 in direction Y will then result in a movement of the roller pin with respect to the seat, which will cause the movement of the retaining element 12313 in direction X.

Analogously, as can be seen in Figure 12D, the conversion means 12410 may comprise a cam 12411 connected to the release means. The cam can act on a convex seat of the actuating element 12400, so that a movement of the release means in direction Z can result in a movement of the actuating element 12400 in direction Y.

Even though the invention has been described with reference to certain embodiments, each comprising one or more specific features, it is clear that the invention should not be considered limited to said embodiments and that alternative embodiments may be obtained by combining one or more features of the described embodiments.
