Description

Description Title of the invention: Device for detecting the displacement and / or position of a deadbolt, latch bolt or similar type of hardware locking

[0001] = The invention relates to a device for detecting displacement and position of bolt, such as deadbolt, latch bolt or similar locking hardware.

[0002] — The present invention will find its application in the field of hardware. building and relates to devices for detecting the state of opening, closing and Locking of a door or window frame. It concerns, more particularly- relatedly, devices designed to detect the different locked positions and unlocked locking mechanisms of a fitting equipping such joinery.

[0003] It is increasingly common to equip a door or window of a dwelling or a any technical room for a home automation function that it previously lacked beforehand.

[0004] Thus, means of ensuring at a distance from the perfect locking of a door or window, or even the means of remote control of opening or closing such joinery, or means of controlling the opening in the ventilation position. In reality, the market current offers a whole range of security or control methods applicable to a door or window.

[0005] — In particular, several devices for detecting the locked and unlocked state are known. locked with a locking mechanism fitted to such a French window. Such devices Positive detection methods can take different forms and be of mechanical or contactless, electrical or even electronic.

[0006] — Thus, magnetic detection devices capable of locating the movement of a part of the locking mechanism during a lock command rusting or, conversely, unlocking.

[0007] For example, in the case of a door or window fitted with a locking mechanism rusting, of the cremone bolt or cremone-lock type, this one includes a mechanism of control generally located at the height of the front frame of an opening of this door or window. One of its functions is to operate operating rods extending in a rebate along this opening jamb to operate one or several locking mechanisms. Through angle drives, such rods of maneuvers can also be extended at the level of the upper crossbeams and / or lower parts of this opening, again to act on additional locking mechanisms tional and / or on partial opening control devices, by lowering or- Trebâillée de l'ouverture. The magnetic detection devices mentioned above are very often installed parallel to such an operating rod, in the rebate of the opening or fixed part or in a suitable notch made at the level of this rebate. Furthermore, there are detection devices designed to detect the position of a locking element such as a deadbolt or latch bolt in a locking hardware control mechanism. The distinctive feature of such a bolt is its movement, which occurs perpendicular to the stile or rail of the door or window frame housing this locking hardware control mechanism. In this direction of movement, space is usually limited due to the often reduced thickness of a door or window sash or rail, thus increasing the glazing area. A magnetic detection device operating in this direction of movement of a deadbolt or latch bolt represents a significant space requirement, whether it is located within the locking mechanism's control housing or at the level of the strike plate with which the bolt interacts. Such additional bulk very often results in a more substantial notch, depending on the case, on the opening or the fixed part to accommodate a larger control mechanism or strike plate housing. Furthermore, when acting, for example, from the frame to detect the position of a deadbolt or latch corresponding to a locking mechanism mounted on a door or window sash, the proper functioning of the detection device is sensitive to positional misalignments that generally occur over time between the sash and the frame. Indeed, such a misalignment results in a change in the air gap between the magnetic detection device and the bolt, the position of which must then be determined. Conversely, installing an electrical or electronic detection device on the opening sash, particularly within the locking mechanism's control box, necessitates bringing a power supply to that sash. While a wired connection is more reliable over time compared to a self-contained power supply, such as a battery, this wired connection must necessarily be made through the moving, often hinged, mounting of the sash on its fixed frame. Such a wired connection is therefore under considerable stress and presents a significant risk of severance. A primary objective of the invention is to design a position detection device for a deadbolt or latch bolt that is capable of effectively meeting the space constraints imposed by detection devices. existing. A second objective that this invention aims to achieve is to facilitate the installation of such a detection device on the frame of a joinery whose locking hardware is installed on an opening, guaranteeing its reliability despite the risks of misalignment that may occur between the opening and its frame over time. Another objective of this invention is to be able to associate such a detection device with a French window locking hardware without profound modification of the components of the locking hardware. According to yet another objective of the invention, the detection device can be fitted to an existing joinery, without additional notching, or dismantling of the components of a locking hardware, generally mounted on the opening, in this case its control mechanism and other locking elements, such as the operating rods. It was within the framework of a first inventive approach that it was thought to ensure this position detection of a deadbolt or latch bolt by transforming its displacement, which is perpendicular to the upright or the crossbar in relation to which it extends, into a proportional displacement, as the case may be, in translation or in rotation, of an actuator capable of cooperating with means of position detection, in particular electrical or electronic. Advantageously, the detection device according to the invention is designed to be fitted to a strike plate into which this deadbolt or latch is intended to engage. In particular, this detection device is designed to be retrofitted to the joinery in cooperation with such a strike plate, to equip it with home automation functionalities which it previously lacked. Thus, the invention relates to a device for detecting the displacement and / or position of a locking hardware bolt, of the deadbolt type, or similar, movable between at least one unlocked position and at least one locked position in which it engages in a housing of a strike plate, said detection device comprising electrical or electronic displacement detection means connected to transmission means capable of transmitting information related to an electrical signal received through said detection means to a processing unit, characterized in that it comprises an actuator cooperating with said detection means and comprising a probe designed to extend in and / or in front of the housing of the strike plate in such a way as to cooperate with the bolt and subject the actuator, under the action of a displacement of said bolt, to a translational or rotational displacement,capable of being detected by said detection means. Advantageously, the actuator is designed to be attached to a joinery, in particular in the rebate of the opening or fixed part, in the extension of a strike plate for receiving a bolt. The advantages arising from the present invention consist in the fact that the detection of the displacement and / or position of a bolt is achieved by transforming its displacements into a translation or rotation of an actuator. Consequently, the displacement detection of this actuator can occur in the rebate of the stile or rail from which the bolt extends, and the detection device according to the invention is easily installed on a window or door frame, particularly in the rebate of the sash or the fixed frame. This detection device according to the invention makes it possible to avoid an additional notch in the joinery or a deep modification of the locking hardware. In particular, this detection device is capable of being fitted, after the fact, to such joinery without removing or modifying the components of the locking hardware that equips it. The invention further relates to a door or window type joinery, comprising a locking hardware including a bolt capable of moving from at least one unlocked position to at least one locked position to engage in a strike plate, and comprising a detection device according to the invention. Other aims and advantages of the present invention will become apparent during the following description, relating to an example of embodiment. Understanding this description will be facilitated by referring to the attached drawings in which: [Fig.1] is a schematic representation of a window frame comprising a cremone bolt type locking mechanism to which a detection device, according to the invention, is associated. [Fig.2] is a schematic and cross-sectional representation of a detection device according to a first embodiment of the invention illustrating its interaction with a deadbolt of a locking fitting shown partially, said deadbolt being in the unlocked position; [Fig.3] is a representation similar to [Fig.2], with the deadbolt shown in the locked position; [Fig.4] is a schematic, perspective and exploded view representation of the detection device according to this first embodiment in cooperation with a strike plate in which a deadbolt is planned to extend, actuated by a control mechanism of a locking fitting also partially illustrated, [Fig. 5] is a schematic and perspective representation of the detection device corresponding to figures | to 3, with an actuator according to a first example of execution; [Fig.6] is a representation similar to [Fig.4] with an actuator corresponding to a second mode of execution; . [Fig.7] is a schematic and cross-sectional representation of a detection device according to a second embodiment of the invention illustrating its interaction with a deadbolt of a locking fitting shown partially, said deadbolt being in the unlocked position; [Fig.8] is a representation similar to [Fig.6], with the deadbolt shown in the locked position; [Fig.9] is a schematic, perspective and exploded view representation of the detection device according to this second embodiment in cooperation with a strike plate in which a deadbolt is planned to extend, actuated by a control mechanism of a locking fitting also partially illustrated, As shown in the figures of the attached drawings, the present invention relates to a detection device 1 intended to detect the movement and / or position of a bolt 2, of the deadbolt, latch bolt or similar type. Referring to [Fig.1], illustrating a joinery, in this case a window 3, it includes at least one opening 4 mounted, in the illustrated example, pivoting around a vertical axis on a fixed frame 5. At the level of its front jamb 6, opposite the pivoting axis, the opening 3 is provided with a control mechanism 7 for a locking fitting 8, illustrated here exclusively as an example, in the form of a cremone bolt lock. It is quite clear that the present invention is by no means limited to such an installation of a locking device 8 on a window or door frame. Thus, the mechanism 7, which the user operates by means of a handle 9 or a key, can be mounted at the height of a rail 10 of this window or door frame. Similarly, one can imagine installing the locking device 8 and its control mechanism 7 on the fixed frame 4. Returning to the example illustrated in this [Fig.1], this control mechanism 7 takes position in a rebate notch in this front jamb 6 of the opening 4. It is designed to act on one or more operating rods 11 extending in the rebate of this front jamb 7, while also being capable of being extended in the rebate of the cross member 10. The control mechanism 7 of such a locking fitting 8 of the cremone type lock also acts on at least one deadbolt 2 and / or a latch bolt which will be referred to generically as a bolt in the rest of the description for ease of understanding. As illustrated in figures 2 and 3, on the one hand, and 7 and 8, on the other hand, this bolt 2 under the action of this control mechanism 7 is capable of occupying at least one locked position 12 and at least one unlocked position 13 by perpendicular movement to the front post 6 of the opening 4 in the illustrated embodiment. At least in the locking position 12, this bolt 2 is projecting into the rebate of this front jamb 6 of the opening 4 to engage in a strike plate 14 arranged correspondingly on the front jamb 6A of the fixed frame 5. In contrast, in its unlocked position(s) 13, this bolt 2 engages in whole or in part in the housing of the control mechanism 7, this by moving backward from this projecting locking position 12, in a direction substantially perpendicular to the front jamb 6 of the opening 4. The detection device 1 according to the invention has the function of detecting the displacements of such a bolt 2 between its locking position(s) 12 and its unlocked position(s) 13, and / or of identifying each of these positions. For this purpose, and as shown in Figures 4 and 9, this detection device 1 comprises electrical or electronic displacement detection means 15, wired or autonomous power supply means 16, and transmission means 17 capable of transmitting information relating to the position and / or displacement of the bolt 2 to a processing unit 18. More precisely, the transmission means 17 receive an electrical signal from the detection means 15 to which they are connected and transmit information related to this received electrical signal to the processing unit 18. The transmission means 17 may, again, be wired, but will preferably be wireless, of the radio or other type. As for the means of detecting displacement 15, they can take any form. According to the invention, they will preferably be of the contactless, optical or magnetic type. In particular, according to the invention, the detection device 1 comprises an actuator 19 including a feeler 21. This is designed to extend in and / or in front of the housing 23 of the strike plate 14 in such a way as to cooperate with the bolt 2 and subject the actuator 19, under the action of a displacement of said bolt 2, in particular between its locking position 12 and unlocked position 13, to a translational or rotational displacement, which is capable of being detected by said detection means 15 with which this actuator 19 cooperates. Referring more particularly to Figures 2 to 6 relating to a first embodiment of the invention, the actuator 19 takes the form of a slide 20 equipped with the feeler 21 cooperating with the bolt 2 to subject this slide 20 to a translation under the impulse of a displacement of the bolt 2 between a locked position 12 and an unlocked position 13 and vice versa. More specifically, In particular, this translation of the slider 20 under the impulse of the feeler 21 occurs substantially in a direction 22 perpendicular to the direction 24 of movement of the bolt 2. In this embodiment, the feeler 21 is designed to extend at least partially into the housing 23 of the strike plate 14 in which the bolt 2 is intended to engage during its movement from an unlocked position 13 in the direction 24 of its locking position 12. In particular, the actuator 19 defined by the slide 20 is subjected to elastic return means 25 to return the feeler 21 to an active position 26, in particular in which it is able to extend in front of the passage of the bolt 2 in the housing 23 of the strike plate 14. This feeler 21 is, moreover, configured in the form of a ramp so that, under the action of this movement of the bolt 2 in the locking direction 26, it gradually disappears as the bolt 2 passes and pushes the slide 20 back in the translation direction 22, against the action of the elastic return means 25. Conversely, in the event of displacement of the bolt 2 in the unlocking direction, these elastic return means 25 push the slide 20 back in the opposite direction to return the feeler 21 to its active position 26. As seen in figures 2 to 6, the slider 20 can be defined as a blade 27, one end 28 of which is folded to define the probe 21 in the form of a ramp, and the opposite end 29 of which is guided in translation by means of suitable guiding means 30 associated with a housing 31 which comprises the detection device 1. According to an example of an embodiment visible in figures 4 and 5, the blade 27 extends in the longitudinal continuation of this housing 31. It should be noted that according to a second embodiment visible in [Fig.6], this blade 27 is not necessarily straight but may have, if necessary and by way of example, a lateral step or any other shape to adjust the longitudinal positioning of the probe 21 relative to the strike plate 14 intended to receive it. The housing 31 can be equipped with means 32 for fixing to the joinery, in this case, in the illustrated embodiment, in the rebate of the front upright 6A of the fixed frame 5, substantially in line with the strike plate 14. This housing 31 can accommodate the elastic return means 25, for example in the form of a spring 25A. Thus, this can bear, on the one hand, against the bottom of a suitable housing 31A in this housing 31 and, on the other hand, against a shoulder 29A at the level of the slide 20. In particular, such a shoulder 29A can be defined by folding the blade 27 in its end portion opposite to that containing the probe 21. The housing 31 can also integrate the electrical or electronic displacement detection means 15 and / or the transmission means 17. In another embodiment corresponding to that illustrated in the figures, the housing 31 is reported, at its end 33, opposite to that from which the slider 20 extends, on an end 34 of a sensor housing 35 integrating said detection means 15 and / or transmission means 17. According to the invention, the slider 20, here in the form of a blade 27, has at its end 29 guided in the housing 31 an extension 36 designed to cooperate with said electrical or electronic detection means 15. These are defined as being able to transform, through this extension 36, the movement of the slider 20, therefore of the actuator 19, into an electrical signal, possibly proportional, which can be interpreted by the processing unit 18. Preferably, it is placed remotely; it can be integrated into a local or remote home automation unit. As for the transmission means 17 capable of transmitting information related to the electrical signal emitted by the detection means 15, they are advantageously constituted by a radio, Wi-Fi or other transmitter capable of communicating with a related receiver equipping the processing unit 18. These transmission means 17 can also be supplemented by means of connection to the Internet network for transmission of information to a remote processing unit. Figures 7 to 9 illustrate a second embodiment of the invention. In this case, the actuator 19 takes the form of a rocker 20A equipped with the feeler 21 cooperating with the bolt 2 to rotate this rocker 20A under the impulse of a movement of the bolt 2 between a locked position 12 and an unlocked position 13, and vice versa. More specifically, this rotation of the rocker 20A under the impulse of the feeler 21 occurs substantially around an axis 37, notably perpendicular to the plane of the bolt 2 and therefore to the direction of movement of the latter. In this embodiment, the feeler 21 is designed to extend at least partially in front of the housing 23 of the strike plate 14 in which the bolt 2 is intended to engage during its movement from an unlocked position 13 in the direction 24 of its locking position 12. In particular, the actuator 19, defined by the rocker 20A, is subjected to return means by its own weight and / or of elastic type 25A to return it to an active position 26, that is to say in a position in which this feeler 21 extends in front of the housing 23 of the strike plate 14 while awaiting the engagement of the bolt 2 in this housing 23. This feeler 21 is advantageously defined by an elastic blade 38 extending the rocker 20A beyond its pivot axis 36, precisely to extend in front of said housing 23 of the strike plate 14. It is preferably defined elastically deformable so as to yield by deformation under the impulse of this bolt 2, beyond a defined rocker stroke 37 sufficient to detect the displacement of the bolt 2 from the unlocked position 13 in the direction 24 of the locked position 12, Conversely, when the unlocking command is given, this elastic blade returns to its initial shape, in particular straight, then to its active position 26 under the impulse of the return means 25, to detect the passage of the locking position 12 of the bolt 2 into its unlocked position 13. As seen in figures 7 to 9, the rocker 20A has an extension 40, on the opposite side of the feeler 21 with respect to the axis of rotation 37, to cooperate, at the end part 41 of this extension 40, with the detection means 15. These are defined to detect a variation in distance, in particular of air gap, between these and this end part 41 during the rotation of the rocker 20A and, therefore, to detect a displacement of the bolt 2. Ingeniously, the rocker 20A is designed symmetrically about a transverse median plane to facilitate the reversibility of the detection device 1 depending on whether it is applied to a sash 4 pivoting to the right or left relative to the fixed frame 5. Thus, depending on the opening direction, the end portion 41 of the rocker 20A can define a feeler 21 and vice versa. They are therefore both designed in the form of an elastically deformable blade 38; 38A. In a preferred embodiment, the rocker 20A takes the form of a U-shaped bracket 42 having a fixing arm 43 at the ends of which extend two parallel arms 44, 45 suitable for defining, indifferently, pivot axes of this rocker 20A, in cooperation with a fixing base 46 under which the fixing arm 43 engages, in particular to bring the rocker 20A into a joinery rebate, more particularly of the fixed frame 5 in the embodiment represented. Just as in the embodiment corresponding to figures 2 to 6, the displacement detection means 15 can be positioned in a sensor housing 35. This can also integrate the transmission means 17. The advantages arising from the present invention are substantial. In particular, it makes it possible to detect the movement of a bolt without modifying the components of the locking hardware equipped with this bolt and without even needing to carry out an operation to dismantle these components of a locking hardware already fitted to a joinery.
