Description

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

[0001] The invention relates to a device for detecting the movement and position of a bolt, such as a deadbolt, a half-turn bolt or similar locking fitting.

[0002] 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 a 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 equipping such joinery.

[0003] It is becoming increasingly common to equip a door or window of a home or any technical room with a home automation functionality that it previously lacked.

[0004] Thus, there are currently commercially available means for remotely ensuring the perfect locking of a door or window, or even means for remotely controlling the opening or closing of such joinery, or even means for controlling opening in the ventilation position. In reality, the current market offers a whole range of security or control means applicable to a door or window.

[0005] 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 may take different forms and be mechanical or contactless, electrical or even electronic in nature.

[0006] Thus, magnetic detection devices are known which are capable of detecting the movement of a part of the locking fitting during a locking command or, conversely, unlocking command.

[0007] For example, in the case of a door or window equipped with locking hardware, of the espagnolette or espagnolette-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 upright of the opening to actuate one or more locking members. Through angle transmissions, such operating rods can also be extended to the level of the upper and / or lower crosspieces of this opening, again to act on additional locking members and / or on partial opening control devices, by lowering or en- the opening was left open.

[0008] The magnetic detection devices mentioned above are very often installed parallel to such an operating rod, in the opening or fixed frame rebate or in a suitable notch made at the level of this rebate.

[0009] There are, moreover, detection devices designed to detect the position of a locking member of the deadbolt or half-turn bolt 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 locking fitting control mechanism.

[0010] In this direction of movement, the space requirement is usually restricted due to the often reduced thickness of an upright or crosspiece of a door or window opening to increase the glazing clearance. Such a magnetic detection device acting in this direction of movement of a deadbolt or latch bolt represents a significant space requirement, whether it is installed in the housing of the control mechanism of the locking fitting or at the height of the strike plate with which this bolt is intended to cooperate.

[0011] Such additional bulk very often results in a larger cutout, depending on the case on the opening or the frame to accommodate a larger control mechanism or striker housing.

[0012] Furthermore, by acting, for example, from the 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 correct operation of the detection device is sensitive to position adjustments generally occurring over time between the opening and the frame. Indeed, such adjustment results in a modification of the air gap between the magnetic detection device and the bolt, the position of which must be determined.

[0013] Conversely, installing an electrical or electronic detection device on the opening, particularly in the housing of the locking fitting control mechanism, 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 power supply, for example in the form of a battery, this wired connection must necessarily be made through the mobile, often articulated, mounting of the opening on its fixed frame.

[0014] Such a wired connection is therefore subject to heavy stress and presents a significant risk of sectioning.

[0015] A first aim of the invention consists in designing a device for detecting the position of a deadbolt or half-turn bolt which is capable of effectively responding to the space constraints represented by the detection devices existing.

[0016] 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 misadjustment likely to occur between the opening and its fixed frame over time.

[0017] Another objective of this invention is to be able to associate such a detection device with a French window locking fitting without extensive modification of the components of the locking fitting.

[0018] According to yet another objective of the invention, the detection device can be fitted to existing joinery, without additional notching or dismantling of the components of a locking fitting, generally mounted on the opening, in this case its control mechanism and other locking members, such as the operating rods.

[0019] 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 half-turn bolt by transforming its movement, which is perpendicular to the upright or the crosspiece in relation to which it extends, into 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 electrical or electronic.

[0020] Advantageously, the detection device according to the invention is designed to equip a latch in which this deadbolt or half-turn is intended to engage.

[0021] In particular, this detection device is designed to be retrofitted to the joinery in cooperation with such a latch, to equip it with home automation functions which it previously lacked.

[0022] 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 movement detection means connected to transmission means capable of transmitting to a processing unit information relating to an electrical signal perceived through said detection means, characterized in that it comprises an actuator cooperating with said detection means and comprising a feeler designed to extend into and / or in front of the housing of the striker in a manner capable of cooperating with the bolt and subjecting the actuator, under the action of a movement of said bolt, to a translational or rotational movement,capable of being detected by said detection means..,

[0023] Advantageously, the actuator is designed to be attached to a joinery, in particular in the rebate of an opening or fixed frame, in the extension of a strike plate for receiving a bolt.

[0024] The advantages arising 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 translation or a rotation of an actuator. As a result, the detection of movement of this actuator can take place 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 joinery, in particular in the rebate of an opening or fixed frame.

[0025] This detection device according to the invention makes it possible to avoid additional notching at the level of this joinery or a profound modification of the locking fitting.

[0026] In particular, this detection device is capable of retrofitting such joinery without removing or modifying the components of the locking fitting with which it is fitted.

[0027] The invention also relates to a 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 strike plate, and comprising a detection device according to the invention.

[0028] Other aims and advantages of the present invention will appear during the description which follows, relating to an exemplary embodiment.

[0029] Understanding of this description will be facilitated by referring to the attached drawings in which:

[0030] [Fig-1] is a schematic representation of a joinery in the form of a window comprising a cremone-type locking fitting with which a detection device is associated, in accordance with the invention,

[0031] [Fig.2] is a schematic and sectional representation of a detection device according to an embodiment of the invention illustrating its interaction with a deadbolt of a partially shown locking fitting, said deadbolt being in the unlocked position;

[0032] [Fig.3] is a representation similar to [Fig.2], the deadbolt being illustrated in locking position;

[0033] [Fig.4] is a schematic, perspective and exploded representation of the device of detection according to the embodiment in cooperation with a strike plate in which a deadbolt actuated by a control mechanism of a locking fitting is provided to extend, also partially illustrated,

[0034] 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 position of a bolt 2, of the deadbolt, half-turn bolt or similar type.

[0035] Referring to [Fig.l], illustrating a 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 fixed frame 5. At 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.

[0036] It is quite 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 operates by means of a handle 9 or a key, can be mounted at the height of a crosspiece 10 of this joinery. Similarly, it is possible to imagine installing the locking fitting 8 and its control mechanism 7 on the fixed frame 4.

[0037] To return to the example illustrated in this [Fig.l], 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.

[0038] 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 half-turn bolt which will be generically called a bolt in the remainder of the description to facilitate understanding.

[0039] 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 displacement perpendicular to the front upright 6 of the opening 4 in the illustrated embodiment.

[0040] At least in the locking position 12, this bolt 2 projects into the rebate of this front upright 6 of the opening 4 to engage in a strike plate 14 arranged in correspondence on the front upright 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, by moving back relative to this projecting locking position 12, in a direction substantially perpendicular to the front upright 6 of the opening 4.

[0041] 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.

[0042] For this purpose and as visible in [Fig.4], this detection device 1 comprises electrical or electronic displacement detection means 15, means wired or autonomous electrical power supply 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 perceived electrical signal. The transmission means 17 can, here again, be wired, but will preferably be chosen to be non-wired, of the radio or other type.

[0043] As for the movement detection means 15, they can take any form of embodiment. According to the invention, they will preferably be chosen to be of the contactless, optical or magnetic type.

[0044] In particular, 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 in a 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 13 positions, to a translational or rotational movement, capable of being detected by said detection means 15 with which this actuator 19 cooperates.

[0045] Preferably, the processing unit 18 is placed remotely. It can be integrated into a local or remote home automation unit.

[0046] 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, Wi-Fi or other transmitter capable of communicating with a corresponding 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 the information to a remote processing unit.

[0047] Figures 2 to 4 illustrate an 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 and an unlocked position 13 and vice versa. More particularly, this rotation of the rocker 20A under the impulse of the feeler 21 occurs substantially around an axis 37, in particular perpendicular to the plane of the bolt 2 and therefore the direction of movement of the latter.

[0048] In the embodiment, 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 the direction 24 of its locking position 12. In particular, the actuator 19, defined by the rocker 20A, is subject to return means by its own weight and / or of the type elastic 25A to bring it back into an active position 26, that is to say into a position in which this feeler 21 extends in front of the housing 23 of the strike plate 14 while waiting for the bolt 2 to engage in this housing 23.

[0049] 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 striker 14. It is preferably defined elastically deformable to yield by deformation under the impulse 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,

[0050] Conversely, during the unlocking command, this elastic blade returns to its initial shape, in particular rectilinear, then to its active position 26 under the impulse of the return means 25, to detect the passage from the locking position 12 of the bolt 2 into its unlocked position 13.

[0051] As visible in Figures 7 to 9, the rocker 20A comprises an extension 40, on the side opposite the feeler 21 relative to the axis of rotation 37, to cooperate, in the end part 41 of this extension 40, with the detection means 15. These are defined to detect a variation in distance, in particular in 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.

[0052] Cleverly, the rocker 20A is designed symmetrically 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 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.

[0053] In a preferred embodiment, the 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 attach the rocker 20A to the joinery rebate, more particularly of the fixed frame 5 in the embodiment shown.

[0054] The movement detection means 15 can take position in a sensor housing 35. This can also integrate the transmission means 17.

[0055] 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 to carry out an operation to dismantle these components of a locking fitting already attached to a joinery.
