Description

Device for detecting the movement and/or position of a bolt, of the deadbolt, half-turn or similar type of locking fitting

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

The present invention will find its application in the field of building hardware and relates to devices for detecting the state of opening, closing and locking of door or window type joinery. It relates, more particularly, to 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 feature that it did not previously have.

Thus, one currently finds on the market means making it possible to remotely ensure the perfect locking of a door or window, even means of remote control of opening or closing of such joinery, or even means opening control in the 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 for detecting the locked and unlocked state of a locking fitting fitted to such a patio door are known. Such detection devices can take different embodiments and be mechanical or contactless, electrical or even electronic in nature.

Thus, magnetic detection devices are known that are able to identify the movement of a part of the locking fitting during a locking command or, conversely, an unlocking command.

By way of example, in the case of a door or window fitted with a locking fitting, of the espagnolette or espagnolette-lock type, the latter comprises a control mechanism generally located at the height of the front upright of an opening of this door or window. One of its functions consists in acting on operating rods extending in the rebate along this amount of the opening to actuate one or more locking devices. Through corner transmissions, such operating rods can also be extended at the level of the upper and/or lower crosspieces of this opening, here again to act on additional locking members and/or on opening control devices partial, by lowering or opening the sash ajar.

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

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 space requirement is usually limited due to the often reduced thickness of an upright or a crosspiece of a door or window opening to increase the clearness of the glazing. Such a magnetic detection device acting in this direction of movement of a deadbolt or half-turn bolt represents a not insignificant bulk, 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 brought to cooperate.

Such additional bulk very often leads to a larger notch, depending on the case, on the sash or the frame to accommodate a larger control mechanism or striker box.

Furthermore, by acting, for example, from the fixed frame to detect the position of a deadbolt or half-turn corresponding to a locking fitting mechanism mounted on a door or window opening, the proper functioning of the detection is sensitive to position maladjustments generally occurring over time between the opening and the fixed frame. Indeed, such a misadjustment 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 electric or electronic detection device, in particular in the box of the control mechanism of the locking fitting, requires bringing a 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 fixed frame. .

Such a wired connection is therefore highly stressed and presents a non-negligible risk of disconnection.

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

A second objective which this invention proposes to achieve consists in facilitating the installation of such a detection device on the frame of a carpentry whose locking fitting is installed on an opening, guaranteeing its reliability despite the risks of misadjustment likely to occur between the opening and its fixed frame over time.

Another object of this invention consists in being able to associate such a detection device with a window-door locking fitting without major modification of the components of the locking fitting.

According to yet another object of the invention, the detection device can be fitted to an existing carpentry, without additional notching, or disassembly of the components of a locking fitting, generally mounted on the opening, in this case its control mechanism and other locking devices, such as operating rods.

It is within the framework of a first inventive approach that it was thought to ensure this detection of the position of a deadbolt or latchbolt by transforming its movement, which is perpendicular to the upright or the crosspiece with respect to which it extends, in a proportional movement, as the case may be, in translation or in rotation, of an actuator capable of cooperating with position detection means, in particular electric or electronic.

Advantageously, the detection device according to the invention is designed to be fitted to a strike plate in which this deadbolt or latch bolt is intended to engage.

In particular, this detection device is designed to be retrofitted to the carpentry in cooperation with such a striker plate, to equip it with home automation functionalities which it did not previously have.

Thus, the invention relates to a device for detecting the movement and/or position of a locking fitting bolt, of the deadbolt type, or the like, mobile 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 electric or electronic displacement detection means connected to transmission means capable of transmitting information in relation to a signal towards a processing unit perceived through said means of detection, characterized in that it comprises an actuator cooperating with said means of detection and comprising a feeler designed to extend into and/or in front of the housing of the striker in such a way as to cooperate with the bolt and subjecting the actuator, under the action of a displacement of said bolt, to a displacement in translation or rotation, able to be detected by said detection means ..

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

The advantages resulting from the present invention consist in that the detection of displacement and/or position of a bolt is carried out by transforming its displacements into a translation or a rotation of an actuator. Therefore, the detection of movement of this actuator can intervene in the rebate of the upright or the crosspiece from which the bolt extends and the detection device according to the invention is easy to install on a carpentry, in particular in sash or frame rebate.

This detection device according to the invention makes it possible to avoid additional notching at the level of this joinery or a major modification of the locking fitting.

In particular, this detection device is likely to equip, a posteriori, such joinery without removal or modification of the components of the locking fitting which equips it.

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

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

The understanding of this description will be facilitated by referring to the attached drawings in which:

is a schematic representation of joinery in the form of a window comprising a locking fitting of the espagnolette type with which is associated a detection device, in accordance with the invention,

is a schematic cross-sectional representation of a detection device according to one embodiment of the invention illustrating its interaction with a deadbolt of a locking fitting shown partially, said deadbolt being in the unlocked position;

is a representation similar to the , the deadbolt being shown in the locked position;

is a schematic, perspective and exploded representation of the detection device according to the embodiment in cooperation with a strike plate in which is provided to extend a deadbolt actuated by a control mechanism of a locking fitting also partially illustrated,

As shown in the figures of the accompanying drawings, the present invention relates to a detection device 1 intended to detect the movement and/or the position of a bolt 2, of the deadbolt, latchbolt or similar type.

By referring to the , illustrating joinery, in this case a window 3, the latter comprises at least one sash 4 mounted, in the example shown, pivoting about a vertical axis on a fixed frame 5. At its front upright 6 , opposite to the pivot axis, the opening 3 is provided with a control mechanism 7 of the locking fitting 8, illustrated, here exclusively by way of example, in the form of a locking espagnolette.

It is obvious that the present invention is in no way limited to such an implantation of locking fitting 8 on a carpentry. 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. Similarly, one can imagine installing the locking fitting 8 and its control mechanism 7 on the fixed frame 4.

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

The control mechanism 7 of such a locking fitting 8 of the locking espagnolette type also acts on at least one deadbolt 2 and/or a half-turn bolt which will be referred to generically as a bolt in the remainder of the description for ease of understanding.

As illustrated in 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 illustrated embodiment.

At least in the locking position 12, this bolt 2 projects in the rebate of this front upright 6 of the opening 4 to engage in a striker plate 14 arranged in correspondence on the front upright 6A of the fixed frame 5. Unlike , in its unlocked position or positions 13, this bolt 2 engages in whole or in part in the housing of the control mechanism 7, this by moving back with respect to this projecting locking position 12, in a direction substantially perpendicular to the front upright 6 of the sash 4.

The detection device 1 according to the invention has the function of detecting the movements 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 visible in the , this detection device 1 comprises electric or electronic displacement detection means 15, wired or autonomous electric power supply means 16, as well as transmission means 17 capable of transmitting information relating to the position and/or displacement of the bolt 2 in the direction of a processing unit 18. More exactly, the transmission means 17 receive an electric signal from the detection means 15 to which they are connected and transmit in the direction of the processing unit 18 information in relation to this perceived electrical signal. The transmission means 17 can, here again, be wired, but will be chosen, preferentially, non-wired, of the radio or other type.

As for the displacement detection means 15, they can take any form of embodiment. According to the invention, they will be chosen, preferably, the non-contact, optical or magnetic type.

More particularly, according to the invention, the detection device 1 comprises an actuator 19 comprising a feeler 21. The latter is designed to extend into and/or in front of the housing 23 of the striker 14 so as to cooperate with the bolt 2 and subjecting the actuator 19, under the action of a movement of said bolt 2, in particular between its locked 12 and unlocked 13 positions, to a movement in translation or rotation, able to be detected by said detection means 15 with which cooperates this actuator 19.

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 advantageously constituted by a radio transmitter, Wi-Fi or other 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 2 to 4 illustrate one 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 subject this rocker 20A to a rotation under the impulse of a movement of the bolt 2 between a locking position 12 is an unlocked position 13 and vice versa. More particularly, this rotation of the rocker 20A under the impulse of the feeler 21 intervenes substantially around an axis 37, in particular perpendicular to the plane of the bolt 2 and therefore to the direction of movement of the latter.

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

This sensor 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 striker 14. It is preferably defined elastically deformable to yield by deformation under the impetus of this bolt 2, beyond a defined tilting stroke 37 sufficient to detect the movement of the bolt 2 from the unlocked position 13 in direction 24 of the locking position 12,

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 in its unlocked position 13.

As visible in FIGS. 7 to 9, rocker 20A comprises an extension 40, on the side opposite feeler 21 with respect to 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 of distance, in particular of air gap, between the latter and this end part 41 during the rotation of the flip-flop 20A and, therefore, to detect a displacement of the bolt 2.

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 with respect to the fixed frame 5. Thus, according to this direction of opening, the end part 41 of rocker 20A can define a feeler 21 and vice versa. They are therefore both designed in the form of an elastically deformable strip 38; 38A.

In a preferred embodiment, rocker 20A takes the form of a U-shaped rider 42 comprising a fixing branch 43 at the ends of which extend two parallel branches 44, 45 capable of defining, indifferently, pivot axes of this rocker 20A, in cooperation with a fixing base 46 under which the fixing branch 43 engages, in particular to bring the rocker 20A into the carpentry rebate, more particularly of the fixed frame 5 in the embodiment shown.

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

The advantages flowing 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 to disassemble these components from a locking fitting already reported on a carpentry.
