The joinery 1 illustrated in the appended figures consists of a door consisting of a frame 2 associated with an opening 3.

The frame 2 can be made of metal profiles; it comprises two vertical uprights 21 and 22 connected by an upper cross member 23 and by a threshold cross member 24.

The opening 3 is of the pivoting type; one of its vertical edges 31 is pivotally mounted about a vertical pivot axis 4 on the upright 22 of the frame 2, for example by means of a set of hinges (not shown).

The frame 2 and the opening 3 of the joinery 1 are provided with locking means 5 between them, which comprise a dead bolt lock 51 fitted to said opening 3, cooperating with a keeper 52 formed in said frame 2.

And this joinery 1 also includes locking detection means 6, detailed below, adapted to detect the locked and unlocked positions of the opening 3 relative to the frame 2, these locking detection means comprising:

- a sensor means 61 designed capable of detecting a locked position of the opening 3 on the frame 2,

means 62 for processing the information detected by said sensor means 61, and

- Means 63 for transmitting said detected information to receiving means R suitable for processing the information received and ensuring its supply / accessibility to the user.

The lock 51 is mounted on the vertical border 32 of the opening 3 opposite the border 31 articulated on the pivot axis 4.

This lock 51 comprises a latch bolt 511 operated by a handle 512, as well as a dead bolt 513 operated for example by means of a key cylinder 514.

The deadbolt 513 is made of metallic material, for example steel; it is mounted in the vertical edge 321 of the opening edge 32; conventionally it is maneuvered in horizontal translation so as to be retracted inside the opening 3 in the unlocked position, and to project from said edge 321 of the opening edge 32 in the locked position.

The keeper 52 is mounted in a vertical rebate 211 of the frame upright 21 and more particularly in the face 2111 of this rebate 211 which is oriented in the direction of the opposite upright 22 (and therefore in the direction of the vertical edge 321 of the sash border 32, when the door 32 is in the closed position).

This keeper 52 comprises a throwing bolt housing 521 designed to cooperate with the throwing bolt 511 so as to close the opening leaf 3 on the frame 2. The keeper 52 also comprises a deadbolt housing 522 designed to cooperate with the deadbolt 513 so as to ensure the locking of the closing of the opening 3 relative to the fixed 2.

In the embodiment illustrated in FIG. 1, the lock 51 is of the three-point type, comprising two additional locks, one 515 in the upper part and the other 516 in the lower part, operated by the throwing bolt causing a hook to by means of an adapted integrated linkage.

These two latches 515 and 516 are operated in vertical translation along the edge 321 of the opening edge 32; they are adapted to cooperate each with a locking cavity 53, 54 formed in the upright 21 of the frame 2, and more particularly in the face 2111 of the rebate 211 of the frame 2.

The deadbolt housing 522 is delimited by an opening 7 of generally rectangular shape and by a wall structure 8 forming a sort of sleeve or internal sock of cleanliness.

In the joinery 1 illustrated in the appended figures, the keeper 52 comprises a keeper plate 53 and a keeper housing 54 integrating the locking detection means 6.

The strike box 54 is housed in a strike housing 2112 formed in the upright 21 of the frame 2 and which opens into the face 2111 of the rebate 211 (said receiving face 2111); and this strike box 54 is here partially covered by the strike plate 53 fixed on said reception face 2111.

More specifically, the strike plate 53 is fixed in a longitudinal groove 2113 provided in the receiving face 2111, to integrate its thickness; and the strike housing 2112 opens into this longitudinal groove 2113.

The strike plate 53 is made of metallic material, for example steel. It comprises an orifice 531 defining the opening of the thrust bolt housing 521, and an orifice 532 defining the opening 7 of the deadbolt housing 522; this plate 53 is fixed in the receiving face 2111, and more particularly in the longitudinal groove 2113, by means of screws 55.

The strike box 54 is delimited by walls 541, here made of plastic, the internal surface of which delimits an internal volume suitable for receiving the locking detection means 6, and part of which constitutes at least part of the structure of wall 8 of the deadbolt housing 522.

More specifically, as detailed in FIGS. 3 and 4, the strike box 54 includes a reservation 542, comprising a bottom 5421, two end walls 5422, 5423 and a side wall 5424, constituting a part of the wall structure 8 deadbolt housing 522. The side wall 5424 extends perpendicular to the bottom 5421; it is provided with an external surface oriented on the side of said deadbolt housing 522 and with an opposite internal surface. This reservation 542 includes a front opening 5425 facing the bottom 5421, and a lateral opening 5426 facing the side wall 5424.

The strike box 54 is fixed in the strike housing 2112 of the frame 21 by means of screws, and the strike plate 53 at least partially covers this strike box 54 so that its orifice 532 comes opposite the opening 5425 front of the housing reservation 542, to define the deadbolt housing 522.

One of the walls of the frame upright 21 is positioned opposite the lateral opening 5426 of the reservation 542 to together form the wall structure 8 of the deadbolt housing 522.

The components of the locking detection means 6 are organized inside the strike box 54 so as to ensure effective detection of the presence or absence of the deadbolt 513 in the deadbolt housing 522, and for ensure the transmission of this information to the receiving means R.

For this, as can be seen in FIGS. 3 to 7, the sensor means 61 is positioned opposite the internal surface 82 of the side wall 5424 of the housing reservation 542. This sensor means 61 is here generally in place and it extends in a plane parallel or substantially parallel to one of the side faces of the deadbolt 513, just near and opposite this side face when the deadbolt 513 is in its locked position inside of the deadbolt housing 522.

This sensor means 61 is advantageously of the inductive type, designed to detect the presence of metal (and therefore of the deadbolt 513) in the deadbolt housing 522.

Preferably, the inductive sensor 61 comprises an oscillator circuit, and the processing means 62 comprise a microcontroller designed capable of measuring the oscillation frequency of this oscillator circuit.

The transmission means 63 are conventional and here of the wireless type; they advantageously consist of conventional radio means.

A battery system 64 integrated in the strike box 54 is provided for the electrical supply of the sensor means 61, the processing means 62 and the wireless transmission means 63.

These various elements, namely the sensor means 61, the processing means 62, the wireless transmission means 63 and the battery system 64, constituting the locking detection means 6, are carried here by a support card 65 mounted in the strike box 54, for example in the form of a printed circuit board integrating the necessary electrical connections.

In FIGS. 2 and 3, it can be seen that the strike box 54 has an extension 543 which extends outside the size of the strike plate 53, once the two structures are mounted on the frame upright 21. This extension 543 incorporates at least part of the wireless transmission means 63, so as to limit the risks of disturbance of the signal transmission to the receiving means R, due to the metallic nature of the strike plate 53.

This extension 543 advantageously extends slightly projecting relative to the part of the housing 54 intended to be covered by the strike plate 53, so that its front face extends in the plane of the front face of the strike plate, once the keeper 52 is mounted (as shown in Figure 2).

The receiving means R consist of a means of displaying information such as a computer, a tablet, a smartphone, via a modem / router type device.

As an alternative, it should be noted that the battery system can be deported outside the strike box.

Also, the means of transmitting the detected information to the receiving means can be of the wired type.

The locking detection means according to the invention are particularly discreet, invisible in the closed position of the opening and almost invisible in the open position of this opening. Their structure and positioning participate in obtaining good reliability of the detection of the locking and of the transmission of information to the receiving means.
