Description

The invention relates to a device for detecting movement and position of a bolt, such as a deadbolt, latch bolt or similar locking fitting.

The present invention will find its application in the field of building hardware and relates to devices for detecting the opening, closing and locking state of door or window type joinery. It concerns, more particularly, devices designed to detect the different locked and unlocked positions of locking members of a fitting fitted to such joinery.

It is increasingly common to equip a door or window of a home or any technical room with a home automation functionality which it did not previously have.

Thus, we currently find on the market means making it possible to remotely ensure the perfect locking of a door or window, or even means of remote control of opening or closing of such joinery, or even means opening control in ventilation position. In reality, the current market offers a whole range of security or control means applicable to a door or window.

In particular, several devices are known for detecting the locked and unlocked state of a locking fitting fitted to such a French window. Such detection devices can take different embodiments and be mechanical or contactless, electrical or even electronic in nature.

Thus, magnetic detection devices are known capable of detecting the movement of a part of the locking fitting during a locking or, conversely, unlocking command.

For example, in the case of a door or window equipped with a locking fitting, of the cremone or cremone-lock type, this includes a control mechanism generally installed at the height of the front upright of an opening of this door or window. One of its functions consists of acting on operating rods extending in a rebate along this amount of the opening to actuate one or more locking members. Through corner references, such operating rods can also be extended at the level of the upper and/or lower crossbars of this opening, again to act on additional locking members and/or on opening control devices partial, by closing or ajar the sash.

The magnetic detection devices mentioned above are very often installed parallel to such an operating rod, in the opening or frame rebate or in a suitable notch made at the level of this rebate.

There are, moreover, detection devices designed to detect the position of a locking member of the deadbolt or latchbolt type of a locking fitting control mechanism. The particularity of such a bolt lies in its movement which occurs perpendicular to the upright or the crosspiece of the opening receiving this mechanism for controlling the locking fitting.

In this direction of movement, the bulk is usually restricted due to an often reduced thickness of an upright or a crosspiece of a door or window opening to increase the clarity of the glazing. Such a magnetic detection device acting in this direction of movement of a deadbolt or latchbolt represents a significant amount of space, whether it is installed in the housing of the control mechanism of the locking fitting or at the height of the striker with which this bolt is required to cooperate.

Such additional space very often leads to a more substantial notching, depending on the case, on the opening or the frame to accommodate a larger control mechanism or striker box.

Furthermore, by acting, for example, from the frame to detect the position of a deadbolt or latch bolt corresponding to a locking fitting mechanism mounted on a door or window opening, the proper functioning of the locking device detection is sensitive to position adjustments generally occurring in the time between the opening and the frame. In fact, such an adjustment results in a modification of the air gap between the magnetic detection device and the bolt, the position of which must be determined.

Conversely, an installation on the opening of an electrical or electronic detection device, in particular in the housing of the control mechanism of the locking fitting, requires bringing an electrical power supply to the level of this opening. If a wired connection is more reliable over time compared to an autonomous type power supply, for example in the form of a battery, this wired connection must necessarily be made through the mobile assembly, often articulated, of the opening on its frame. .

Such a wired connection is therefore heavily stressed and presents a significant risk of sectioning.

The document WO 02/31295 A1 discloses a security module for a door. In a pre-locking step of a bolt on the door side is recognized by the fact that the bolt hits a leaf spring arranged inside the striker and pivots the latter. Pivoting the leaf spring triggers a corresponding signal via a push button, also installed inside the striker, as a result of which a particular alarm system is "armed". The security module has the disadvantage of being difficult to install and requiring a suitable striker to accommodate the leaf spring and the push button.

A first aim of the invention consists of designing a device for detecting the position of a deadbolt or latchbolt which is able to respond effectively to the space constraints represented by existing detection devices.

A second objective that this invention aims to achieve consists of facilitating the installation of such a detection device on the frame of a joinery whose locking fitting is installed on an opening, while guaranteeing its reliability despite the risks of maladjustment likely to occur between the opening and its frame over time.

Another objective of this invention consists of being able to associate such a detection device with a French window door locking fitting without profound modification of the components of the locking fitting.

According to yet another objective of the invention, the detection device can equip existing joinery, without additional cutting or dismantling of the components of a locking fitting, generally mounted on the opening, in this case its control mechanism and other locking devices, such as the operating rods.

It is within the framework of a first inventive approach that we thought of ensuring this detection of the position of a deadbolt or latchbolt by transforming its movement, which is perpendicular to the upright or crossbar in relation to which it extends, in a proportional movement in rotation, of an actuator capable of cooperating with position detection means, in particular electrical or electronic.

Advantageously, the detection device according to the invention is designed to equip a striker in which this deadbolt or latch bolt is intended to engage.

In particular, this detection device is designed to be retrofitted onto the carpentry in cooperation with such a strike, to equip it with home automation functionalities of which it was previously lacking.

Thus, the invention relates to a device for detecting the movement and/or position of a locking fitting bolt, of the deadbolt type, or similar movable between at least one unlocked position and at least one locking position in which it engages in a housing of a striker, said detection device comprising electrical or electronic variation detection means connected to transmission means capable of transmitting information relating to a signal to a processing unit electrical perceived through said detection means, characterized in that it comprises an actuator cooperating with said detection means and comprising a sensor designed to extend in and/or in front of the housing of the striker so as to cooperate with the bolt and subject the actuator, under the action of a movement of said bolt, to a rotational movement, capable of being detected by said detection means. Said detection means are able to be arranged outside the volume of the keeper.

Advantageously, the actuator is designed to be attached to a joinery, in particular in the sash or frame rebate, in the extension of a strike plate for receiving a bolt.

The advantages resulting from the present invention consist in that the detection of movement and/or position of a bolt is carried out by transforming its movements into a rotation of an actuator. As a result, the detection of movement of this actuator can intervene in the rebate of the upright or the crosspiece from which extends the bolt and the detection device according to the invention are easier to install on joinery, in particular in the sash or frame rebate.

This detection device in accordance with the invention makes it possible to avoid additional cutting at the level of this joinery or a deep modification of the locking fitting.

In particular, this detection device is capable of equipping, a posteriori, such joinery without removing or modifying the components of the locking fitting which equips it.

The invention also relates to door or window type joinery, comprising a locking fitting comprising a bolt capable of moving from at least one unlocked position into at least one locking position to engage in a striker, and comprising a device detection according to the invention.

Other aims and advantages of the present invention will become apparent during the description which follows, relating to an exemplary embodiment.

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, latchbolt or similar type, for door or window type joinery.

Referring to the figure 1 , illustrating the joinery, in this case a window 3, this comprises at least one opening 4 mounted, in the example illustrated, pivoting around a vertical axis on a frame 5. At the level of its front upright 6 , opposite the pivot axis, the opening 3 is provided with a control mechanism 7 for locking fitting 8, illustrated here exclusively by way of example, in the form of a cremone lock.

It is obvious that the present invention is in no way limited to such an installation of locking fitting 8 on a joinery. Thus, the mechanism 7 on which the user intervenes by means of a handle 9 or a key, can be mounted at the height of a crosspiece 10 of this joinery. Likewise, we can imagine installing the locking fitting 8 and its control mechanism 7 on the frame 4.

To return to the example illustrated in this figure 1 , this control mechanism 7 takes position in a rebate notch of this front upright 6 of the opening 4. It is designed to act on one or more operating rods 11 extending in rebate of this front upright 7, while being capable of being extended into a cross rebate 10.

The control mechanism 7 of such a locking fitting 8 of the cremone lock type also acts on at least one deadbolt 2 and/or a latch bolt which will be generically called a bolt in the rest of the section. description to make it easier to understand.

As illustrated in the figures 2 And 3 , this bolt 2 under the action of this control mechanism 7 is capable of occupying at least one locking position 12 and at least one unlocked position 13 by movement perpendicular to the front upright 6 of the opening 4 in the embodiment illustrated.

At least in the locking position 12, this bolt 2 protrudes into the rebate of this front upright 6 of the opening 4 to engage in a keeper 14 arranged correspondingly on the front upright 6A of the frame 5. Unlike , 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 back relative to this protruding locking position 12, in a direction substantially perpendicular to the front upright 6 of the opening 4.

The function of the detection device 1 according to the invention is to detect the movements of such a bolt 2 between its locking position(s) 12 and its unlocked position(s) 13, and/or to identify each of these positions.

For this purpose and as visible in the figure 4 , this detection device 1 comprises electrical or electronic variation detection means 15, wired or autonomous electrical power supply means 16, as well as transmission means 17 capable of transmitting information relating to the position and/or movement of the bolt 2 towards 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 towards the processing unit 18 information relating to this electrical signal perceived. The transmission means 17 can, here again, be wired, but will be chosen, preferably, non-wired, of the radio type or other.

As for the variation detection means 15, they can take any form of embodiment. According to the invention they will be chosen, preferably, of the contactless type, optical or magnetic. Advantageously, the variation detection means 15 can be in the form of an inductive sensor.

Very particularly, according to the two embodiments of the invention, the detection device 1 comprises an actuator 19 comprising a feeler 21. This is designed to extend in and/or in front of the housing 23 of the keeper 14 of manner capable of cooperating with the bolt 2 and subjecting the actuator 19, under the action of a movement of said bolt 2, in particular between its locking 12 and unlocked positions 13, to a rotational movement, capable of being detected by said detection means 15 with which this actuator 19 cooperates. The actuator 19 takes the form of a rocker 20A equipped with the feeler 21 capable of cooperating with the bolt 2 to subject this rocker 20A to rotation under the impulse of a movement of the bolt 2 between a locking position 12 and an unlocked position 13 and vice versa. The rotation takes place around a first axis of rotation 37. Said detection means 15 are arranged outside the volume of the keeper 14.

The first axis of rotation 37 can be arranged outside the keeper 14.

A sensor box 35, which the detection device 1 comprises, 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 frame 5, substantially in the extension of the keeper 14. The sensor box 35 can be arranged outside the volume of the keeper 14. The sensor box 35 can accommodate at least the electrical or electronic variation detection means 15 and be provided with means 32 for fixing on woodwork. The means 32 for fixing to the joinery can allow the sensor box 35 to be arranged outside the volume of the keeper 14. The means 32 for fixing to the joinery can include clipping elements allowing the sensor box 35 to be clipped to the joinery.

A housing 31, which the detection device 1 comprises, can house the elastic return means 25, for example in the form of a spring 25A. Thus, it can be supported, on the one hand, at the bottom of a suitable housing 31A in this housing 31 and, on the other hand, on a shoulder at the level of the actuator 19.

The sensor box 35 can also integrate the electrical or electronic variation detection means 15 and/or the transmission means 17. In another embodiment corresponding to that illustrated in the Figures 5A to 11 , the box 31 is attached, at its end 33, opposite that from which the actuator 19 extends, on one end 34 of the sensor housing 35 integrating said detection means 15 and/or the transmission means 17.

The housing 31 may include clipping means 31B which can be attached to complementary clipping means 35A of the sensor housing 35 in order to attach the housing 31 to the sensor housing 35. The clipping means 31B can for example be formed by an elastically deformable tongue. provided with a notch at its end and the complementary clipping means 35A can for example be formed by a housing, formed in the sensor housing 35 for example, capable of receiving the notch of the elastically deformable tongue.

Preferably, the processing unit 18 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 in relation to the electrical signal emitted by the detection means 15, they are constituted, advantageously, 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.

The first axis of rotation 37 can be perpendicular to the plane of the bolt 2 and the direction of movement of the latter.

The actuator 19, defined by the rocker 20A, can be capable of tilting around the first axis of rotation 37 with a first angle α of rotation predefined between an active position 26 in which the probe 21 is defined capable of extending beyond in front of the housing 23 of the striker 14 while waiting for the engagement of the bolt 2 in this housing 23 and an intermediate position 47.

The first predefined rotation angle α can for example be between 0.5° and 5°, preferably between 1° and 2°.

The detection device 1 may comprise a stop element 48 capable of preventing rotation of the actuator 19 beyond the intermediate position 47. The figures 2 to 4 illustrate a first embodiment of the invention. THE figure 5 to 7 illustrate a second embodiment of the invention. In these two cases, the actuator 19 takes the form of a rocker 20A equipped with the feeler 21 cooperating with the bolt 2 to subject this rocker 20A to rotation under the impulse of a movement of the bolt 2 between a locking position 12 and an unlocked position 13 and vice versa. More particularly, this rotation of the rocker 20A under the impulse of the probe 21 occurs substantially around the first axis 37 of rotation, in particular perpendicular to the plane of the bolt 2 and therefore to the direction of movement of the latter.

In these two embodiments, the feeler 21 is designed to extend at least partly in front of the housing 23 of the striker 14 in which the bolt 2 is intended to engage in its movement from an unlocked position 13 in direction 24 of its locking position 12. Very particularly, the actuator 19, defined by the rocker 20A, is subjected to first return means by its own weight and/or of elastic type 25A to return it to the active position 26 , that is to say in a position in which this feeler 21 extends in front of the housing 23 of the striker 14 while waiting for the engagement of the bolt 2 in this housing 23.

According to the first embodiment of the invention illustrated in the figures 2 to 4 , this feeler 21 is advantageously defined by an elastic blade 38 extending the rocker 20A beyond the first axis of rotation 37, precisely to extend in front of said housing 23 of the keeper 14. It is preferably defined elastically deformable to yield by deformation under the impulse of this bolt 2, beyond a defined tilting stroke sufficient to detect the movement of the bolt 2 from the unlocked position 13 in the direction 24 of the locking position 12. In this embodiment, the elastically deformable blade 38 is in direct contact with the rocker 20A, without articulation thereon.

Conversely, during the unlocking command, this elastic blade regains its initial shape, in particular rectilinear, then 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.

In this embodiment, the rotational movement of the rocker 20A around the first axis of rotation 37 is strictly transmitted to the blade 38.

As visible on the figures 2 to 11 , according to the two embodiments of the invention, the detection device comprises an actuating element 40, connected to the actuator 19 on the side opposite the feeler 21 relative to the first axis of rotation 37, to cooperate, in the end part 41 of this actuating element 40, with the detection means 15. These are defined to detect a variation in distance, in particular air gap, between the latter and this end part 41 during the rotation of the rocker 20A and, therefore, to detect a movement of the bolt 2. The actuating element may comprise a metallic and/or ferromagnetic part 41A. This metallic and/or ferromagnetic part 41A can be arranged facing the detection means 15.

The actuator 19 and/or the rocker 20A, preferably together with the actuating element 40, makes it possible to transfer a movement of the bolt 2 from the inside of the striker 14 to the outside of the striker 14 Thus, the electronics which include the sensor 15 can be offset from the striker 14.

The actuating element 40 can be arranged in the housing 31 and/or be mounted to rotate freely around a third axis of rotation 56. The actuating element 40 can be attached to the housing 31.

The actuating element 40 can be clipped to the housing 31 so as to be rotatably mounted around the third axis of rotation 56. Thus, the actuating element 40 can be provided with a tab 56A and the housing 31 can be provided with a notch 56C receiving one end 56B of the tab 56A. Alternatively, the housing 31 can be provided with the tab 56A and the actuating element 40 can be provided with the notch 56C receiving the end 56B of the tab 56A. The end 56B of the tab 56A and the notch 56C can form the third axis of rotation 56. The end 56B of the tab 56A and the notch 56C can have a cross section that is at least partially circular.

The housing 31 can be provided with at least one clipping device 31D allowing the housing 31 to be fixed to the upright by a screw. For this purpose, the housing 31 can be provided with a hole 31E which can be passed through by a fixing screw, the hole 31E preferably being an oblong hole.

The actuating element 40 can be able to tilt around the third axis of rotation 56 with a second predefined angle of rotation β between a detection position 57 in which the actuating element 40 can cooperate, preferably in the end part 41 of this actuating element 40, with the detection means 15 and a spacing position 58.

The second predefined rotation angle β can for example be between 5° and 32°, preferably between 10° and 20°.

The actuating element 40 may be capable of tilting around the third axis of rotation 56 with the second predefined angle of rotation β as a result of the tilting of the actuator 19 around the first axis of rotation 37 with the first angle α of rotation .

According to the two embodiments of the invention, the electrical or electronic variation detection means 15 and/or the transmission means 17 may have an independent electrical energy supply. For this purpose, the detection device 1 may comprise at least one power battery making it possible to supply the electrical or electronic variation detection means 15 and/or the transmission means 17 with electrical energy.

According to the first embodiment of the invention illustrated in the figures 2 to 4 , cleverly, the rocker 20A is designed symmetrical with respect to a transverse median plane to facilitate the reversibility of the detection device 1 depending on whether it is applied to an opening 4 pivoting to the right or to the left relative to the frame 5. Thus, depending on this opening direction, the end part 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 the embodiment shown in the figures 2 to 4 , the rocker 20A takes the form of a U-shaped jumper 42 comprising a fixing branch 43 at the ends of which extend two parallel branches 44, 45 capable of defining, indifferently, the pivot axes of this rocker 20A, in cooperation with a fixing base 46 under which the fixing branch 43 engages, in particular to attach the rocker 20A to the joinery rebate, more particularly of the fixed frame 5 in the embodiment shown. The fixing base 46 can be part of the housing 31.

In the first embodiment of the invention illustrated in the figures 2 to 4 , the elastic return means 25 can be positioned on the fixing base 46 of the housing 31, preferably positioned in the center of the fixing base 46 and/or at inside of it. The elastic return means 25 can be formed by an elastically deformable blade (not shown in the figures) which can rest on the one hand on the fixing branch 43 and on the other hand on the rocker 20A.

The variation detection means 15 can take position in the sensor box 35. This can also integrate the transmission means 17.

According to the second embodiment of the invention illustrated by the figures 5 to 11 , the actuator 19 may include a base 49 and a tongue 50 forming the feeler 21. The tongue 50 can be mounted on the base 49 free to rotate relative to the base 49 around a second axis of rotation 51.

According to one possibility, the first axis of rotation 37 and/or the second axis of rotation 51 and/or the third axis of rotation 56 can be parallel to each other. The first axis of rotation 37 and/or the second axis of rotation 51 and/or the third axis of rotation 56 may be non-aligned with respect to each other.

The base 49 can be formed from a bent metal wire. The bent metal wire may comprise a plurality of sections. The sections can extend perpendicularly to the direction of movement of the bolt 2. A first section among the sections can constitute a first shaft 37A extending along the first axis of rotation 37. The first shaft 37A can be received in a bearing 31C. The bearing 31C can be provided in the housing 31. The first shaft 37A allows rotation around the first axis of rotation 37. A second section among the sections can constitute a second shaft 51A extending along the second axis of rotation 51. The second shaft 51A allows rotation around the second axis of rotation 51 of the tongue 50 relative to the base 49. A third section among the sections can constitute a connection section 59, preferably forming one end of the base 49 The connection section 59 allows the connection of the base 49 to the detection element 40. The connection section 59 allows the detection element 40 to be tilted around the third axis of rotation 56 with the second angle of rotation β predefined as a result of the tilting of the actuator 19 around the first axis of rotation 37 with the first angle of rotation α.

The distance between the first axis of rotation 37 and the second axis of rotation 51 may be less than the distance between the first axis of rotation 37 and the third axis of rotation 56. The distance between the first axis of rotation 37 and the section of connection 59 can be greater than the distance between the third axis of rotation 56 and the connection section 59. These characteristics make it possible to increase the sensitivity of the detection device 1 by lever arm effect.

The tongue 50 can be a part molded from a resin comprising at least one polymer or else a part molded from metal or a metal alloy.

The tongue 50 can be subjected to second return means by its own weight and/or of elastic type 52 to return it to a service position 54. The service position 54 defines a relative position between the actuator 19 and the tongue 50. The elastic type return means 52 can, on the one hand, rest on the tongue 50 and, on the other hand, rest on the base 49. The tongue 50 is held in the service position 54 when the actuator 19 takes the active position 26 and/or the intermediate position 47 by the second return means 52.

The second return means 52 can be in the form of a helical torsion spring with tangent arms 55. The second return means 52 can be made of a metallic material. Preferably, the second return means 52 are made from a folded metal wire. Such second return means 52 are represented in the Figure 8C . In this case, one of the tangent arms 55 of the helical spring can rest on the tongue 50 and the other tangent arm 55 of the helical spring can rest on the base 49.

The tongue 50 may have a hole 53. The tongue can be fitted onto a section of the bent metal wire, preferably onto a terminal section of the bent metal wire, by the hole 53.

The second axis of rotation 51 can be arranged inside the volume occupied by the striker 14 in the active position 26 and/or in the intermediate position 47 of the actuator 19.

The actuating element 40 can be arranged on the side opposite the feeler 21 relative to the first axis of rotation 37, to cooperate, in the end part 41 of this actuating element 40, with the detection means 15 housed in a sensor box 35. The actuating element 40 according to the second embodiment can be a part molded from a resin comprising at least one polymer. The actuating element 40 can be attached to the connection section 59 of the base 49. The actuating element 40 can be attached to the connection section 59 by fitting the actuating element 40 onto the section or by clipping the actuating element 40 onto the section.

When the fitting 8 is locked, the bolt 2 is moved from the unlocked position 13 of the bolt 2 to the locked position 12 of the bolt 2. At the start of the stroke of the bolt 2 from the unlocked position 13 to the locked position 12, the bolt 2 hits the feeler 21 to, in the two embodiments of the invention, tilt the actuator 19 around the first axis of rotation 37 from the active position 26 towards the intermediate position 47. In the intermediate position and according to the two embodiments of the invention, the stop element 48 prevents rotation of the actuator 19 beyond the intermediate position 47.

Following the tilting of the actuator around the first axis of rotation 37 from the active position 26 towards the intermediate position 47, according to the first embodiment of the invention, the bolt 2 continues its movement towards the locked position 12, to make flex the elastically deformable blade 38 and thus allow the bolt 2 to move towards the locked position 12.

According to the second embodiment of the invention, following the tilting of the actuator around the first axis of rotation 37 from the active position 26 towards the intermediate position 47, the bolt 2 continues its movement towards the locked position 12, to make tilt the tongue 50 around the second axis of rotation 51 and thus allow the movement of the bolt 2 towards the locked position 12.

According to the second embodiment of the invention, the rotational movement of the rocker 20A around the first axis 37 is multiplied by a complementary rotational movement of the actuating element 40 around the third axis 56. Thus, the actuator 19 in conjunction with the detection device 40 forms a means of transferring rotational movements with reduction.

Thus, a very small first angle α of rotation of the rocker 20A around the first axis of rotation 37, of the order of 1°, generates a second, much higher angle of rotation β, of the order of 8°, of actuating element 40 around the third axis 56. The sensitivity of the detection device 1 is greatly increased.

The actuator 19 has a first end formed by the elastically deformable blade 38 or the tongue 50 capable of coming into contact with the bolt 2 and a second free end near the electrical detection means or electronic variation 15. The second free end can be formed by the end 41 of the extension 40.

The detection device 1 according to the invention is adapted to be able to equip pre-existing joinery, in particular without requiring a substantial modification of the striker 14. The detection device 1 according to the invention can be in the form of a modular device, in which in particular the actuator 19 and the electrical or electronic variation detection means 15 constitute separate modules.

The detection device 1 according to the invention makes it possible to relocate the organs requiring space and/or to promote radio transmission and/or access such as the electrical or electronic variation detection means 15. The detection device 1 according to the invention can be adapted to various and varied shapes that the bolt 2 can take.

The detection device 1 according to the invention allows a closing sequence of the fitting 8 in two stages: actuation of the electrical or electronic variation detection means 15 followed by a free complementary movement of the bolt 2. For this purpose, the actuator 19 can be configured to allow actuation of the electrical or electronic variation detection means 15 at the start of the stroke of the bolt 2 from the unlocked position 13 towards the locked position 12 and/or configured to allow free complementary movement of the bolt 2 at the end of travel of the bolt 2 from the unlocked position 13 to the locked position 12.

With the detection device 1 according to the invention, permanent integration of the actuator 19 or the electrical or electronic variation detection means 15 to the striker 14 is not necessary, which allows its use for any type of striker. 14. A specific striker 14 is not necessary for the use of the detection device 1.

The actuator 19 of the detection device 1 according to the second embodiment allows the serialization of two rotary movements around the first axis of rotation 37 and around the second axis of rotation 51 to transform the ample movement of the bolt 2 into one rotation of the actuator 19 by a first acute angle α.

The first elastic return means 25 and the second elastic return means 52 constitute two antagonistic elastic return means, of specific sensitivity, capable of authorizing a rapid movement detection movement of the bolt 2 and a high tolerance of movement of the bolt 2 post detection.

With the detection device 1 according to the invention, no adjustment is necessary to adjust its trigger sensitivity. The operation of the detection device 1 according to the invention is insensitive to standard variations in adjustment and normal wear of the joinery. No modification of the notching zone of the fitting 8 is necessary (no weakening of the joinery by the presence of the electrical or electronic variation detection means 15).

The transmission means 17 can be configured to interact with a home automation environment, such as a home automation box or such as an alarm center.

The detection device 1 according to the invention allows the detection of an intrusion into a property through the carpentry.

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 fitting equipped with this bolt and, without it even being necessary to carry out an operation of dismantling these components of a fitting locking already reported on a carpentry.
