Description

Description Title of the invention: device for detecting the state of a locking or locking member for carpentry 1.

Field of the invention

The field of the invention is that of sensors intended to equip joinery so as to detect their locking and/or condemnation state. 2.

Prior art

[0002] It is increasingly common to see buildings equipped with home automation devices in order to be able to remotely communicate various information concerning them and/or to remotely control some of their organs (ventilation, heating, joinery, etc.) .

[0003] Thus, it is known to implement sensors making it possible to detect the state of a carpentry, for example open (opening releasing the opening of the frame), closed (opening closing the opening of the frame), locked ( opening closing the frame opening and locked lock).

[0004] These sensors, even though they generally make it possible to perform their detection function effectively, nevertheless pose certain problems.

In particular, there are known sensors placed in the rebate of the frame or the opening of a carpentry.

These sensors make it possible to detect whether the opening is open or closed.

100061 Sensors are also known which are directly integrated into the locking system.

They make it possible to detect the locked state of a carpentry.

These sensors are therefore specific to each locking system.

In other words, there are as many sensor references as there are locking system references.

This imposes on the sensor manufacturer as well as on the manufacturer of locking and joinery systems obvious constraints of production and storage of multiple products, which is not industrially efficient.

100071 There is therefore a need to simplify and standardize the implementation of state detection sensors within joinery.

100081 Furthermore, the sensors of the prior art are of the all or nothing type.

In other words, they are able to determine two precise positions of an opening (closed or open) or of a locking system (locked or unlocked).

This therefore requires that the sensor be very precisely placed in the carpentry or the locking system, otherwise it is not able to effectively detect the different states.

This makes it long and delicate to install, which requires the use of skilled labour, which increases the cost of joinery.

100091 In addition, the positioning of these sensors in the rebate induces a risk of disturbance in the remote transmission of the signals delivered by the sensors.

[0010] There is therefore a need to improve these sensors. 3.

Aims of the invention The aim of the invention is in particular to provide an effective solution to at least some of these various problems.

[0012] In particular, according to at least one embodiment, an object of the invention is to provide a device for detecting the state of a locking and/or locking member that can be easily integrated into joinery.

[0013] In particular, the invention aims, according to at least one embodiment, to provide a sensor which is versatile in that it can be integrated into carpentry of different references and/or made of different materials (in particular PVC, aluminium, wood, steel, or a combination of several of these materials...).

Another object of the invention is, according to at least one embodiment, to provide such a sensor which is simple to maintain.

Another object of the invention is, according to at least one embodiment, to provide such a sensor which improves safety.

Another object of the invention is, according to at least one embodiment, to provide such a sensor which can communicate effectively remotely. 4.

Presentation of the invention

[0017] For this, the invention proposes a device for detecting the state of a locking and/or locking member, said sensor being intended to equip a carpentry comprising at least one frame and one opening movable with respect to to the fixed frame and at least one lock comprising at least one locking and/or condemnation member secured to said opening and capable of cooperating with at least one striker secured to said fixed frame.

[0018] Such a device comprises a sensor that can take at least:

[0019] - a locking/locking state taken when said at least one locking and/or locking member cooperates with said at least one keeper, and an unlocking/non-locking state taken when said at least one locking member and /or condemnation does not cooperate with said at least one keeper,

[0020] said device comprising means for securing said sensor to said frame.

Thus, the invention consists in integrating at the level of the frame of a carpentry a state sensor of a locking and/or condemnation member.

[0022] The installation at the level of the frame is much simpler insofar as the available space is greater than on the opening. 3

[0023] In addition, the sensor is completely independent of the locking system, also called a lock.

It is thus integral neither with a locking member (for example a bolt, a roller, a hook, a pin, rod of espagnolette or other) nor with a striker provided to receive the locking member, nor even of the barrel.

[0024] A sensor according to the invention is thus adaptable to different carpentry references equipped with different locking system references.

It thus benefits from great versatility.

A device according to the invention further comprises a housing comprising a housing for said sensor and a portion capable of extending inside a reservation shaped for this purpose in said frame in the extension of said keeper.

[0026] This makes it possible to easily install a device according to the invention within a carpentry and this in a standardized manner.

The device is installed in the extension of the keeper, that is to say after the bottom of the latter.

It is therefore not housed inside the strike.

The box is structurally independent of the strike.

In particular, the box is not formed by the striker or does not form the striker.

Thus, the hinge and the striker can be dismantled separately.

[0027] Such a box comprises a face intended to bear against a face of said fixed frame intended to be oriented towards the inside of a room.

The device according to the invention is thus facing the interior of the building and not installed in the rebate.

[0029] 11 is thus easy to attach the box to the frame or to dissociate it from inside a building without opening the carpentry or dismantling safety devices such as strikers.

This facilitates maintenance and improves safety.

[0030]According to one possible characteristic, said casing comprises an access opening to said housing from said face intended to bear against a face of said fixed frame intended to be oriented towards the inside of a room.

[0031] 11 is thus easy to access the inside of the box from inside a building without opening the carpentry or dismantling safety devices such as strikers.

This facilitates maintenance and improves safety.

[0032]According to one possible characteristic, said sensor comprises detection means capable of evaluating the relative position of said at least one locking and/or locking member with respect to said at least one striker plate, and means for transmitting a signal representative of said relative position.

A device according to the invention thus makes it possible to provide information on the state of the sensor and of the joinery that it equips.

[0034]According to one possible characteristic, said emission means are oriented towards said face of said box intended to bear against a face of said fixed frame intended to be oriented towards the inside of a room.

This improves the transmission of information from the sensor.

Indeed, rather than spreading through the fixed frame towards the opening delimited by it and through the opening when the latter closes the opening, the signals from the sensor spread directly towards the interior of the building.

The sensor signals are thus not disturbed by any obstacle as is the case when they diffuse towards the opening delimited by the fixed frame.

In fact, this zone includes the frame, the striker, the lock and, where appropriate, the opening, the presence of these elements impairing the correct transmission of information from the sensor.

The invention therefore improves the transmission of information from the sensor regardless of the material or materials making up the carpentry (wood, plastic, aluminum, steel or a combination of several of these materials).

[0037] In addition, the fact of broadcasting the information coming from the sensor towards the interior of the building rather than towards the exterior thereof prevents the risk that this information may be recovered from the outside by malicious persons.

According to one possible characteristic, said detection means are intended to be oriented in the rebate in the direction of said at least one locking and/or locking member.

According to one possible characteristic, said sensor belongs to the group comprising:

[0040] - mechanical sensors; optical sensors; capacitive sensors; inductive sensors.

According to one possible characteristic, said sensor is of the linear type configured for:

[0042] - detecting the locking/locking state when said at least one locking and/or locking member is located in a predetermined detection zone inside said at least one striker, and detecting the locking state unlocking/non-locking when said at least one locking and/or locking member is located outside of said detection zone.

This facilitates the installation of the device without requiring precise adjustment of its position in the frame.

[0044] According to one possible characteristic, a device according to the invention comprises means for detecting a variation in the position of said at least one locking and/or locking member inside said at least one striker according to a predetermined frequency, and means for transmitting an alert signal when such a variation according to such a frequency is detected.

[0045] The predetermined frequency will preferably correspond to the frequency signature of burglary actions or tools (manoeuvres of the handle, hammer blows, lever movements with a screwdriver or a crowbar, drill, grinder, etc. .).

This makes it possible to recognize a break-in attempt and issue a signal accordingly if necessary.

According to one possible characteristic, said at least one locking and/or locking member belongs to the group comprising:

[0047] - dead bolts; latch bolts; pebbles; hooks ; trigger bolt; studs.

According to one possible characteristic, a device according to the invention comprises means for visual and/or audible indication of the state of said sensor.

According to one possible characteristic, a device according to the invention comprises autonomous means for supplying energy to said sensor, said autonomous means belonging to the group comprising:

[0050] - the batteries; photovoltaic collector-battery assemblies; energy harvesting type devices.

The invention also relates to joinery comprising a state sensor device for a locking and/or locking member according to any one of the above variants.

[0052] According to one possible characteristic, such joinery belongs to the group comprising:

[0053] doors, gates, windows. 5.

Description of particular embodiments 6.1.

Architecture

[0071] With reference to Figures 1 to 15, an example of a sensor device for detecting the state of a locking and/or locking member of a carpentry, also called a state sensor, is presented.

[0072] Such a sensor device is intended to equip a carpentry comprising at least one front and one movable opening relative to the fixed frame.

It can either be:

[0073] - a door (entrance door, French window, balcony door, service, interior, communication, individual or collective residential, tertiary, industrial, etc.) 7 a gate (garage, fence, etc.); a window (striking, sliding, roofing, etc.).

[0074] Such carpentry conventionally comprises at least one lock comprising at least one locking member, such as for example a latch bolt, a roller, a hook (cf. 130 FIG. 14), a trigger bolt, a stud. .., or a locking member, such as a deadbolt, integral with the opening and capable of cooperating with at least one striker integral with the frame.

In some cases, an organ can be both locking and condemning.

It may for example be a deadbolt which engages in a keeper when the leaf closes the frame to occupy a locked state and then is blocked in position with the cylinder of a lock to occupy a condemned state.

The rest of the description will be made in relation to an application in the field of the front door for detecting the state of a deadbolt.

Of course, this application is not restrictive and any other application may be envisaged as results from the foregoing.

In variants, such a sensor device can therefore make it possible to detect the position of any type of locking and/or locking member of any type of joinery.

The sensor device described here constitutes a deadbolt bottom sensor whose function is in particular to detect the position of a door lock deadbolt and to provide the corresponding information.

[0077] Figure 1 illustrates a perspective view of an entry door 1 conventionally comprising a fixed frame 10 and an opening 11 movable relative to the fixed frame 10.

The door is shown in a state in which the leaf is ajar.

This door 1 conventionally comprises a locking system comprising a lock 12 provided with at least one locking and/or locking member, in particular a bolt, for example a deadbolt 13, integral with the opening 11 and capable of cooperating with at least one keeper 14 secured to the frame 10.

Such a door 1 can be equipped with a sensor device according to the invention so as to make it possible to detect the state in which the deadbolt 13 is located.

As shown in Figures 2 and 3, such a sensor device 2 comprises a box 20.

The box 20 comprises a plate 21 having a so-called outer face 210 and a so-called inner face 211.

The inner face 211 is extended by a receptacle 22 delimiting a housing 220 designed to accommodate a sensor as will be described in more detail below.

[0083] The plate 21 extends laterally beyond the receptacle 22 at at least two opposite ends of the latter, and preferably from its four ends, to form support flanges 23.

These wings can allow ground idarization for example by screwing the box to a fixed frame.

The plate 22 is traversed by an access opening 24 which opens into the housing 220.

This opening 24 is closed by means of a removable cover 25.

[0085] Figures 5 and 6 show a partial cross section of the opening 11 of a door closing the opening of a frame 10.

[0086] As can be seen in these figures, this door comprises a locking system comprising a deadbolt 13 secured to the opening 11 and a strike plate 14 secured to the frame 10.

The frame 10 includes a reservation 110, in the extension of the striker 14, after the bottom of the striker 14, to house the receptacle 22 of the sensor device 2.

The internal face 211 of the plate 21, more precisely the bearing flanges 23, bears against a face 100 of the frame 10 intended to be oriented towards the inside of a room.

The sensor device 2 comprises a detection face 26 which is oriented towards the locking and/or condemnation member.

An opening is made at least partially, at the bottom of the keeper at the level of the detection face 26.

The box 20 is secured to the frame 10 preferably by screwing.

The plate will be for this crossed by holes, at the level of certain support wings, allowing the passage of screws.

Other methods of fixing could of course be implemented, such as clipping, gluing or the like.

Screwing has the advantage of being reversible to allow disassembly of the case.

[0091] The box is fixed with respect to the fixed frame and the sensor is fixed inside the box.

The box 20 can be secured to the frame and dissociated from the frame independently of the striker from which it is structurally independent.

Indeed, the box does not form the striker and the striker does not constitute the box.

The box is not housed in the striker but inside a reservation provided for this purpose in the extension of the striker, after the bottom thereof.

[0093] The keeper can be shaped directly in the frame.

It can also be independent of the fixed frame and secured to it.

The sensor device 2 comprises a sensor 27 which can take at least:

[0095] a locking/locking state taken when the locking and/or locking member, here the bolt 13, cooperates with the corresponding strike plate 14, and an unlocking/non-locking state taken when the locking member and / or condemnation, here the bolt 13, does not cooperate with the striker 14.

For this, the sensor 27 comprises detection means 270 capable of evaluating the relative position of the locking and/or locking member (the bolt 13) with respect to the striker plate 14, and in particular of detecting that the organ cooperates with the striker.

The detection means 270 of the sensor 27 are associated with a processing unit 271 which can for example comprise a programmable unit such as a microprocessor, a random access memory and a read only memory.

Several types of detection means can be implemented.

According to a first variant illustrated in Figures 10 and 11, the sensor will be of the mechanical type.

[0100] In this case, the sensor may be of the open-closed type and include a contactor 28 extending in the keeper 14 in the direction of the bolt 13 movable between:

[0101] an open position taken when the bolt is not housed in the striker plate corresponding to the unlocked/non-locking state, and a closed position in which it is pushed by the bolt when the latter is housed in the latch corresponding to the locked/locked state.

[0102] In one of the positions, the sensor emits an electric signal whereas it emits no electric signal in the other, or at the very least emits different signals in each of the positions, thus allowing the sensor processing unit to generate a signal corresponding to the state of the sensor, i.e. the position of the bolt.

According to a second variant illustrated in Figures 12 and 13, the sensor will be of the optical type.

[0104] In this case, the sensor comprises an emitter cell 29 capable of emitting a light beam in the direction of the bolt and a receiving cell 30 capable of receiving a reflected light beam.

[0105] When the bolt is outside the striker, the sensor emits no signal whereas it emits a signal when the bolt cooperates with the striker, or at the very least emits different signals in each of these positions, thus allowing the sensor processing unit to generate a signal corresponding to the state of the sensor, i.e. the position of the bolt.

[0106] According to a third variant, the sensor will be of the capacitive type.

[0107] In this case, the introduction and the extraction of the bolt (regardless of its material) from the striker generate a variation in capacitance transmitted to the processing unit of the sensor to generate a signal corresponding to the state of the sensor, i.e. the position of the bolt.

According to a fourth variant, the sensor will be of the inductive type.

[0109] In this case, the introduction and extraction of the bolt (made of metallic material) from the striker generate a variation in inductance transmitted to the sensor processing unit to generate a signal corresponding to the state of the sensor. , i.e. the position of the bolt.

The sensor according to the first variant is an all-or-nothing type sensor.

It therefore needs to be implanted with precision in order to function properly.

The sensors according to the other variants are of the linear type.

They are therefore capable of detecting the presence or absence of a locking and/or locking member in a predetermined detection zone of the sensor.

The sensor makes it possible to evaluate the distance between the active zone of the sensor and the end of the locking and/or locking member.

The contours (dimensions) of the detection zone 31 of the sensor, in particular its length L, are determined, will of course be chosen, whatever the type of sensor, depending on the size of the sensor, the striker and of the detected organ.

They will be chosen in particular for each type of joinery, so as to compensate for dimensional tolerances and clearances.

Thus, this type of sensor does not require, in order to operate correctly, to be positioned with great precision.

This facilitates the installation of the sensor compared to an on/off type sensor.

The contours of the detection zone can be programmed so as to define the detection zone L of the sensor to adapt it to the joinery on which the sensor is implemented.

[0114] According to another variant illustrated in FIG. 15, the sensor 27 may comprise a cam 160 held in abutment against the end of the locking and/or locking member 13 and mounted so as to be able to rotate relative to the body of the sensor.

An active element of the sensor will make it possible to determine the angle of rotation D of the cam by optical, capacitive or inductive means and to deduce therefrom the distance X between the end of the locking and/or locking member and the sensor.

In this case, the conversion between the position of the locking and/or locking member is indirect since there is physical contact between the latter and the sensor.

Disturbances due to the environment, except of a mechanical nature, are thus avoided, since the conversion is localized.

[0116] In the case of direct conversions, without contact between the locking and/or locking member and the sensor (second, third and fourth variants), there is a possible risk of disturbance due to the environment (light , parasitic capacitance, magnetic/electric field).

The sensor 27 comprises means 272 for transmitting a signal representative of the relative position of the bolt pai- relative to the striker, or more generally of the state of the sensor.

It may also include reception means for receiving remote control signals.

These transmission/reception means 272 comprise an antenna which is oriented towards the face 210 of the box intended to bear against the face 100 of the frame 10 intended to be oriented towards the inside of a room.

Thus, this antenna transmits in an unobstructed direction, which improves the transmission of information at a distance.

The transmission/reception means 272 can be of the Will type.

Bluetooth, radio or 11 use any wireless communication protocol to allow the sensor to communicate with any receiving unit 32 such as a home automation box, an Internet box, an alarm center, a mobile phone or any other terminal that may be interconnected with a remote server such as the Internet network.

[0119] A user thus has the possibility of knowing the status of the sensor remotely from a Smartphone, a tablet, a computer, etc.

It can also optionally trigger any scenario remotely, such as triggering an alarm or any other action.

[0120] Alternatively or additionally, the sensor may be equipped with a wired output 33 (for example of the NO/NC type) to allow its status to be communicated to a third-party system which would not have been natively provided for wirelessly. .

[0121] Alternatively or in addition, the sensor device 27 may comprise means of visual 33 and/or audible 34 indication of the state of the sensor 27.

A diode 331 of green color could for example light up when the sensor 27 is in locking/locking state while a red light diode 332 can light up when the sensor 27 is in unlocking/non-locking state.

The flashing of one or the other of the diodes or a different lighting color can provide information on an anomaly (battery to be changed, etc.).

[0123] A loudspeaker 341 on the box can emit an audible signal informing of the state of the sensor.

This signal may be emitted during a change of state of the sensor and/or after actuation of an interrogation button 35 placed on the front of the box or remotely.

The sound level may be adjusted so as to perceive the sound information emitted by the sensor device from inside and/or outside the room.

Alternatively or in addition, a vibrator could be implemented to trigger a vibration of the device during a change of state of the sensor and/or after activation of the interrogation button 35.

[0124] The sensor 27 comprises autonomous means for supplying electrical energy 273.

It will preferably be batteries.

This will make it possible to guarantee a high level of service (particularly required by alarm systems) without risk of interruption (in the event of a power cut).

In this case, the batteries will preferably be accessible by removing the removable cover 25.

This allows the user to easily replace the batteries without dismantling the sensor device as a whole or without dismantling a strike plate.

This improves security.

Alternatively, the sensor device may comprise a photovoltaic sensor-battery assembly or else a device of the energy harvesting type (or Energy Harvesting), such as for example a technology of the piezoelectric or other type.

In addition, or alternatively, the sensor device may include an electrical input (12V, 230V, etc.) to allow its connection to an external source.

[0128] The sensor 27 is housed in the box 20.

Thus, the detection means 270, the processing means 271, the transmission/reception means 272 and the independent power supply means are housed in the case, as well as, where applicable, the visual indication means 33 and/or sound 34 of the status of sensor 27. 6.2.

Functioning

[0129] A door can be equipped with an automatic lock.

In this case, all the locking members, apart from the locking members (the deadbolt), engage with the corresponding latches when the door is closed and the handle (or handle) is released.

The deadbolt engages meanwhile with the corresponding keeper when the cylinder is operated to condemn the manipulation of the handle.

The door can take several states.

The closed state corresponds to that in which the opening completely closes the opening delimited by the fixed frame.

Conversely, the open state corresponds to that in which the leaf at least partially releases the opening delimited by the fixed frame.

The locked state is that in which the door is in the closed state and at least some of the locking members (hook rollers, bolts, etc.), apart from the locking members (the deadbolt), cooperate with the corresponding latches.

The condemned state is that in which the cylinder of the lock blocks the operation of the handle and all of the locking members and the locking members (the deadbolt), cooperate with the corresponding strikers.

When a sensor according to the invention equips an entrance door provided with a lock of this type, the sensor makes it possible to detect the situation in which the pole is located:

[0135] - simultaneously closed and condemned, or in the uncondemned state.

A sensor according to the invention is of course not limited to this type of carpentry or to this type of lock.

[0137] In general, it can be implemented to detect that a locking and/or locking member is cooperating with a striker and this in any type of joinery provided that a cutout is provided for this purpose. at the bottom of the mess.

Such a cutout 140 is for example visible at the bottom of the keeper 14 in Figure 14.

The device according to the invention (not shown) is located in the frame behind this cutout.

The state of the sensor can be used for several purposes.

13 101391 In terms of safety, real-time feedback on the status of the sensor can be used to detect the status of the joinery and issue an alert (audible alarm, visual alarm, notifications, etc.).

[0140] In terms of home automation, a real-time feedback of the state of the sensor and/or an interrogation at the request of a home automation unit in communication with the sensor, can make it possible to use the state of the sensor to launch an action (turn on the light, turn off the heating, activate the alarm, etc.).

[0141] In terms of home automation again, a real-time feedback of the state of the sensor and/or an interrogation at the request of a home automation unit in communication with the sensor, can more simply make it possible to communicate for information purposes the sensor status (notifications, icons, etc.). 6.3.

Benefits

A sensor device according to the invention has many advantages, in particular the following.

[0143] A device according to the invention is in particular completely autonomous vis-à-vis the locking system insofar as it is not physically linked either to a striker plate or to a locking-condemnation member.

A device according to the invention is thus versatile in that it can adapt to a large number of locking systems and joinery and/or materials such as aluminum, wood, steel, plastic or a combination of several materials.

A device according to the invention has good completeness insofar as it can make it possible, in certain embodiments, to simultaneously detect two states of a carpentry, i.e. the closed and condemned state or the closed and Locked.

A device according to the invention confers a high level of security:

[0146] - Active: by sensing the state of the carpentry, it raises the status for interrogation ("did I condemn my carpentry on leaving") or gives the alert (launch of an alarm signal in the event of opening or unlocking of the joinery) Passive: by not interfering with the joinery's safety devices (lock, striker plate, barrel, etc.), it preserves their respective safety classifications and does not weaken them.

A device according to the invention is very easy to access.

Its integration on the inside face of the frame, allows easy access and without dismantling components (such as strikes), for the following operations:

[0148] - Installation of the system; Replacing the system Changing the batteries 14 Access to wiring (wired home automation or external power supply).

A device according to the invention has great reliability in terms of transmitting information.

Its integration on the inside face of the frame, rather than in the rebate, allows optimal transmission of radio waves without obstacles in a zone free of radiation.

This in opposition to a sensor which would be located in the rebate of a carpentry and whose "output" of the waves would be "slowed down" or even "blocked" by volumes (metallic or not).

There are therefore no specific studies to be carried out to adapt to each door and each material. 6.4.

Variants

In a variant, the sensor can decode the signature of a break-in or a break-in attempt.

[0151] During a break-in attempt, an intruder, by trying to force the carpentry, will induce a displacement of the locking and/or locking member inside the striker during a low temporal frequency of the order of a second.

[0152] The sensor will then be able to detect a variation, according to a frequency of the order of a second, of the position of the locking and/or locking member inside the striker plate when it is in the locked/locked status.

Thus, if it is detected that the position of the locking and/or locking device inside the striker plate when it is in the locking/locking state, it can be deduced that the carpentry is the object of a break-in attempt and an alert message may be issued to this effect.

A frequency may be predetermined for different break-in actions or different break-in tools (manoeuvres of the handle, hammer blows, lever movements with a screwdriver or a crowbar, drill, grinder, etc.).

Each predetermined frequency will then correspond to the frequency signature of these actions or break-in tools.

The sensor will then be able to identify the type of break-in actions in progress or the type of break-in tools in use by measuring the frequency of variation in the position of the locking member and/or condemnation inside the strike and its comparison with the predetermined frequencies.

According to a variant, a device according to the invention may comprise a vibration sensor, such as for example an accelerometer or the like.

This sensor will make it possible to detect a significant vibration at the level of the opening and/or the frame as the signature of a break-in attempt.

It may be deduced that the carpentry is the subject of a break-in attempt and an alert message may be issued to this effect.

According to a variant, a device according to the invention may comprise a temperature sensor.

This sensor will make it possible to detect a significant variation in temperature at the level of the opening and/or the frame as the signature of an attempted break-in with a torch, for example.

It may be deduced that the carpentry is the subject of a break-in attempt and an alert message may be issued to this effect.

In a variant, a device according to the invention may comprise means for detecting a tearing of the device outside the fixed frame.

It may be deduced that the carpentry is the subject of a break-in attempt and an alert message may be issued in this direction.

All the variants described can be combined with one another.

The invention also relates to a method for detecting the state of a locking and/or locking member by means of a device according to the invention and comprising the steps corresponding to its implementation.
