Description

Title of the invention: Electromagnetic locking device for double or single sliding doors and double or single sliding doors equipped with such an electromagnetic locking device

[0001] The present invention relates to the field of doors, particularly sliding doors, and more specifically to the field of door leaf immobilization devices of the electromagnetic lock type. It relates to an electromagnetic lock device for a double sliding door and a double sliding door equipped with such an electromagnetic lock device. It also relates to an electromagnetic lock device for a single sliding door and a single sliding door equipped with such an electromagnetic lock device.

[0002] Hereafter, the term "door" shall be understood to mean a fixed part (frame, jamb, door frame or woodwork) and a movable part comprising at least one leaf, the movable part being movable relative to the fixed part and capable, in the closed position, of closing the doorway opening and preventing passage. Such an opening is made in a wall or partition in a building or structure.

[0003] Electromagnetic locks are already known that allow the door leaf to be immobilized in the closed position. These electromagnetic locks are most often mounted on swing doors, that is to say, doors whose leaf is mounted to pivot on the fixed part of the door by means of a hinge system.

[0004] These electromagnetic locks comprise, on the one hand, at least one electromagnet forming part of the lock, generally known as a suction cup, of rectangular parallelepiped shape and being connected by electrical cables to an electrical power source to supply it with electric current and, on the other hand, at least one piece of plywood cooperating with the electromagnet (or one of the electromagnets) by electromagnetic attraction in order to achieve the immobilization of the leaf in relation to the frame.

[0005] The mounting of electromagnetic locks on doors is achieved using two supports made of straight metal profiles, namely a plywood support and a magnet support. For reasons of space and power supply to the electromagnet, the magnet support is generally mounted on the fixed part of the door, while the plywood support, which does not require electrical connections, is generally mounted on the door leaf. These supports are integrated into the frame of the door leaf or into the fixed part of the door, or are added by being fixed to the frame of the door leaf or to the fixed part of the door.

[0006] These electromagnetic locks are less commonly used on sliding doors. Among this type of door, we know of sliding doors, called double sliding doors, comprising two sliding leaves extending in the same plane and moving away from or towards each other as they open or close. We also know of single sliding doors comprising a single sliding leaf moving away from or towards a jamb of the frame. These sliding doors are generally equipped with a mechanical or electric lock. However, these mechanical or electric locks present problems with wear, unlocking, or personal safety, or require the use of a key.Furthermore, particularly with regard to double sliding doors, the upper part of the door, i.e. its fixed part, has a reduced surface area which makes it difficult or impossible to attach the supports for the electromagnet and the plywood.

[0007] US patent 8585105 discloses such an electromagnetic lock for a double sliding door, designed to solve the problems of sliding doors with electric or mechanical locks, i.e., a lock with a bolt moved by manual or electrical control. The sliding door described in this patent includes a locking assembly comprising an electromagnetic lock. Two L-shaped brackets support the electromagnet and the plywood of the electromagnetic lock, respectively. Each L-shaped bracket is fixed to the upper or lower part of one of the two door leaves. The electromagnet and the plywood are fixed to the back (outer face) of the vertical arm of the L.

[0008] However, a sliding door equipped with a locking assembly of the type disclosed in US8585105 presents a compactness problem that prevents, in particular, mounting on a small support surface, for example, a support surface formed by a surface of the frame surrounding the glazing of a glazed door leaf. Indeed, this frame is generally narrow because users increasingly seek to maximize natural light by using leaves with the largest possible glazed area. The surface of the frame that can serve as a support, apart from the glazed area, is therefore correspondingly reduced.

[0009] The present invention aims to overcome these drawbacks by proposing a compact electromagnetic locking device for double or single sliding doors, while offering ease of mounting on double or single sliding doors and making it possible to solve the problems of mechanical or electric locks equipping current sliding doors.

[0010] The electromagnetic locking device, according to the present invention, for a double sliding door comprising a frame and two sliding leaves, namely a first sliding leaf and a second sliding leaf, extending in the same plan and being mobile between an open position and a closed position of the double sliding door, the electromagnetic locking device comprising at least one electromagnet, at least one plywood suitable and intended to cooperate by electromagnetic attraction with an attraction face of the electromagnet or one of the electromagnets to immobilize the two sliding leaves in the closed position, a first support to support the electromagnet on the first sliding leaf and a second support to support the plywood on the second sliding leaf, is characterized in that the first and second supports are straight profiles each having at least two flanges, namely a first flange and a second flange, forming a right angle between them,the first wing of the first support being suitable and intended to be fixed to the first sliding leaf and the first wing of the second support being suitable and intended to be fixed to the second sliding leaf, and in that the second wing of the first support is pierced with at least one opening, called the attraction opening, allowing cooperation between the attraction face of the electromagnet or at least one of the electromagnets fixed(s) to the first support and the counterplate(s) fixed(s) to the second support.

[0011] The electromagnetic locking device, according to the present invention, for a single sliding door comprising a frame and a single sliding leaf movable between an open position and a closed position of the single sliding door, the electromagnetic locking device comprising at least one electromagnet, at least one plywood suitable and intended to cooperate by electromagnetic attraction with an attraction face of the electromagnet or one of the electromagnets to immobilize the single sliding leaf in the closed position of the single sliding door, a first support for supporting the electromagnet on the frame and a second support for supporting the plywood on the single sliding leaf, is characterized in that the first and second supports are straight profiles each having at least two flanges, namely a first flange and a second flange, forming a right angle between them,the first wing of the first support being suitable and intended to be fixed to the frame and the first wing of the second support being suitable and intended to be fixed to the single sliding leaf and in that the second wing of the first support is pierced with at least one opening, called the attraction opening, allowing cooperation between the attraction face of the electromagnet or at least one of the electromagnets fixed(s) to the first support and the counter plate(s) fixed(s) to the second support.

[0012] The present invention also relates to a double sliding door equipped with an electromagnetic locking device, the double sliding door comprising a frame and two sliding leaves, namely a first sliding leaf and a second sliding leaf, extending in the same plane and being movable between a an opening position and a closing position of the double sliding door, characterized in that the electromagnetic locking device consists of an electromagnetic locking device according to the present invention and in that the first wing of the first support is fixed on the first sliding leaf and the first wing of the second support is fixed on the second sliding leaf.

[0013] The present invention further relates to a simple sliding door equipped with an electromagnetic locking device, the simple sliding door comprising a frame and a single sliding leaf movable between an open position and a closed position of the simple sliding door, characterized in that the electromagnetic locking device consists of an electromagnetic locking device according to the present invention and in that the first wing of the first support is fixed on the frame and the first wing of the second support is fixed on the single sliding leaf.

[0024] Figures 1 to 3 attached hereto show a double sliding door P, according to the present invention, equipped with an electromagnetic locking device, according to the present invention

[0025] The double sliding door P, according to the present invention, is a sliding door P comprising a frame D and two sliding leaves VI, V2, namely a first sliding leaf VI and a second sliding leaf V2, extending in the same plane.

[0026] Figures 8 and 9 attached hereto show a simple sliding door equipped with an electromagnetic locking device, according to the present invention. Such a simple sliding door P is a sliding door comprising a frame D and a single sliding leaf V3.

[0027] The electromagnetic locking device according to the present invention, equipping the sliding or double door P shown in Figures 1, 2, 3, 8, and 9, comprises two electromagnets 1 and two plywood pieces 2, each capable of cooperating with one of the two electromagnets 1. Figures 4 to 6 show an electromagnetic locking device according to the present invention comprising a single electromagnet 1 and a single plywood piece 2 capable of cooperating with the electromagnet. Such an electromagnetic locking device according to the present invention, equipping such a single or double sliding door P according to the present invention, may comprise a different number of electromagnets 1 and plywood pieces 2 without departing from the scope of the present invention.

[0028] Each sliding leaf VI, V2, or the single sliding leaf V3, thus constitutes the movable part or opening section of the single or double sliding door P. Each sliding leaf VI, V2, or the single sliding leaf V3, is movable between an open position and a closed position of the sliding door P (double or single). The fixed part of the single or double sliding door P is referred to as the frame D. Such a fixed part is also known, for example, as the frame, the door jamb, or the door frame. Such a frame D may comprise two vertical stiles and a crossbar connecting the two stiles at their ends or upper parts.

[0029] It is understood that the single or double sliding door P allows, depending on the position of the single leaf V3 or the leaves VI, V2, to close or open an opening O (or a passage or a bay) which can be made in a wall or partition M, in particular in a building or structure (figures 1 to 3).

[0030] The single sliding leaf V3 or the two sliding leaves VI, V2 may each consist of a panel, glazed or unglazed, solid or perforated. The panel may be of any composition, or made from any material, and may have specific qualities, for example, fire resistance. Such a panel, as also described later, may include a peripheral frame VI2, V22, V32 surrounding it entirely or partially essentially a filling. Each leaf VI, V2, V3 is movable by sliding laterally (or parallel) to the opening O of the door P along a rail. The rail (not visible in the attached figures) can be integrated into the frame D (as in figures 1 and 2), particularly in the upper part of the frame D. The rail can also be visible by being located outside the door P, for example by being fixed to the partition or wall M, particularly in an area located above the opening O of the door P.

[0031] The electromagnetic locking device according to the present invention, fitted to the double sliding door P, makes it possible to immobilize the two sliding leaves VI, V2 in the closed position of the double sliding door P. The electromagnetic locking device according to the present invention, fitted to the single sliding door P, makes it possible to immobilize the single sliding leaf V3 in the closed position of the single sliding door P.

[0032] The electromagnetic closing device, according to the present invention, for a double or single sliding door P, comprises:

[0033] - at least one electromagnet 1,

[0034] - at least one plywood 2 suitable and intended to cooperate by electromagnetism genetic with an attraction face 10 of the electromagnet 1 or of one of the electromagnets 1 to immobilize, in the closed position of the double or single sliding door P, the single sliding leaf V3 (case of the single sliding door P not shown) or the two sliding leaves VI, V2 (case of the double sliding door P shown in figures 1 to 3), and

[0035] - in the case of the simple sliding door P, a first support 3 to support the electromagnet 1 on the frame D and a second support 4 to support the plywood 2 on the single sliding leaf V3, or

[0036] - in the case of the double sliding door P, a first support 3 to support the electromagnet 1 on the first sliding leaf V1 and a second support 4 to support the plywood 2 on the second sliding leaf V2.

[0037] The electromagnet 1 is also known as a suction cup or electromagnetic suction cup. As can be seen in Figures 4 and 7, the electromagnet 1 can be generally rectangular in shape, one face of which forms the attraction face 10, suitable for and intended to cooperate by electromagnetic attraction with the plywood 2. The electromagnet 1 (or suction cup) includes a functional part capable of producing an electromagnetic field when supplied with electric current. The electric current is carried via electrical cables E. Electrical cables may also be provided to carry data signals to and from the electromagnet 1. Such a suction cup (or electromagnet) 1 and its operation are well known to those skilled in the art and are therefore not described further. detailed in the present invention.

[0038] According to the present invention, in such an electromagnetic lock device for a double or single sliding door P, the first and second supports 3, 4 are straight profiles, preferably metallic, each having at least two flanges 30, 31, 40, 41, namely a first flange 30, 40 and a second flange 31, 41, forming a right angle with each other. A right angle is understood to be an angle equal to 90° or approximately equal to 90°. Furthermore, the second flange 31 of the first support 3 is pierced with at least one opening 310, called the attraction opening 310, allowing cooperation between the electromagnet 1 or at least one of the electromagnets 1 fixed(s) to the first support 3 and the counterplate(s) 2 fixed(s) to the second support 4.

[0039] In the case of the double sliding door P (Figures 1 to 3, 7), the first wing 30 of the first support 3 is suitable and intended to (or configured to) be fixed to the first sliding leaf V1, and the first wing 40 of the second support 4 is suitable and intended to (or configured to) be fixed to the second sliding leaf V2. It is understood that, in the mounted state of the electromagnetic locking device on / in the double sliding door P, the first wing 30 of the first support 3 is fixed to the first sliding leaf V1, and the first wing 40 of the second support 4 is fixed to the second sliding leaf V2.

[0040] In the case of the simple sliding door P (Figures 8 and 9), the first wing 30 of the first support 3 is suitable and intended to (or configured to) be fixed to the frame D, and the first wing 40 of the second support 4 is suitable and intended to (or configured to) be fixed to the single sliding leaf V3. It is understood that, in the assembled state of the simple sliding door P, the first wing 30 of the first support 3 is fixed to the frame D, and the first wing 40 of the second support 4 is fixed to the single sliding leaf V3.

[0041] The electromagnet or each electromagnet 1 is fixed on the first support 3, preferably on the second wing 31 of the first support 3. The plywood or each plywood 2 is fixed on the second support 4, preferably on the second wing 41 of the second support 4.

[0042] In the assembled state, as can be seen in particular on [Fig.7], the second wing 31, 41 of each support 3, 4 can extend perpendicularly with respect to the plane of the single leaf V3 or of the leaves VI, V2.

[0043] Each sliding leaf VI, V2, or the single sliding leaf V3, comprises two parallel vertical long sides V10, V20, V30 and two vertical short sides V11, V21, V31 perpendicular to the long sides V10, V20, V30. It is understood that each vertical long side V10, V20, V30 forms a side, or in other words, a lateral face, of the leaf VI, V2, V3 that is parallel (or extends parallel) to the plane of the opening O of the door P and located on one side or the other of the door P. Each small side Vil, V21, V31 is a narrow side also usually called the slant (of the leaf).

[0044] In the case of a double sliding door P, as can be seen in Figures 1 to 3 and 7, one of the short sides V1, V21, referred to as the butt side V1, V21, of each sliding leaf VI, V2, comes or is able to come abut with the butt side V1, V21 of the other sliding leaf VI, V2 in the closed position of the double sliding door P (see Figures 1 and 7 for the closed position). The butt side VI1, V21 is also known as the front side of the sliding leaf. The first support 3 can then be fixed to one of the long sides V1, referred to as the first long side V1, of the first sliding leaf VI by extending (vertically) along (partially or entirely) its butt side V1. In addition, the second support 4 can be fixed on the large side V20 of the second sliding leaf V2 located on the same side (or substantially in the same plane) as the first large side VIO of the first sliding leaf VI.The second support 4 can extend along (partially or entirely) the butt side V21 of the second sliding leaf V2. The second support 4, which has an elongated and straight shape, then extends parallel to the butt side V21. Similarly, the electromagnet or each electromagnet 1 fixed to the first support 3 extends parallel to the butt side V1 of the first leaf VI (and also to the butt side V21 of the second leaf V2) and the plywood or each plywood piece 2 fixed to the second support 4 extends parallel to the butt side V21 of the second leaf V2 (and also to the butt side VI1 of the first leaf VI).

[0045] In the case of a simple sliding door P, as can be seen in Figures 8 and 9, one of the short sides V31, referred to as the butt side V31, of the single sliding leaf V3 is or is capable of butting itself with the frame D, that is, with a stile of the frame D, in the closed position of the simple sliding door. The second support 4 can then be fixed to one of the long sides V30 of the single sliding leaf V3 by extending along (partially or entirely) its butt side V32. The second support 4, which has an elongated and straight shape, then extends parallel to the butt side. Similarly, each plywood piece 2 extends parallel to the butt side.

[0046] As can be seen in particular in Figures 6 and 7, the first support 3 is configured to allow the electromagnet 1, or each electromagnet 1, to be fixed to (or in) the first support 3, occupying a space defined between the first wing 30 and the second wing 31 of the first support 3 on the side of the right angle formed by these wings. This feature makes the device very compact, since the electromagnet 1 fits, in a sense, entirely or essentially within an internal space of the first support 3.

[0047] Preferably, as can be seen in particular in [Fig. 7], the first support 3 is configured to allow the electromagnet 1 or each electromagnet 1 to be fixed to the first support 3 in a position where its attraction face 10 is located within (not shown) or beyond (see in particular [Fig. 7]) the attraction opening 310 or one of the attraction openings 310. It is understood that when the attraction face 10 is located beyond the attraction opening 310 ([Fig. 7]), the electromagnet 1 protrudes from the attraction opening 310. This feature ensures good contact between the attraction face 10 and the plywood 2 cooperating with it.The present invention could also provide, in a form not illustrated, that the attraction face 10 is recessed from the attraction opening 310, but this embodiment is more complex to realize and requires that the opening allow the plywood 2 to be received or to be passed through by the latter to ensure its contact with the recessed attraction face 10.

[0048] Preferably, the section of the first and second supports 3, 4 can have, as can be seen in figures 4 to 7, an L or T shape. The horizontal arm of the L or T can form the first wing 30, 40 and the vertical arm of the L or T can form the second wing 31, 4L. Preferably, the section of the first support 3 can have an L shape and the section of the second support 4 can have a T shape as can be seen in figures 4 to 7.

[0049] Figures 1 to 3, 7, 8, and 9 show that each sliding leaf VI, V2, V3 of the double or single sliding door P can comprise a frame V12, V22, V32 that completely or partially (around its periphery) surrounds a filling V13, V23, V33 of the leaf VI, V2, V3. The frame V12, V22, V32 and the filling V13, V23, V33 thus form a panel, as mentioned above, constituting the leaf V12, V22, V32. The filling V13, V23, V33 can be, for example, but not limited to, glazing, i.e., at least one sheet of transparent material. It is therefore understandable that the electromagnetic locking device, due to its compact size, can easily be fixed to the frame V12, V22, V32 of each sliding leaf VI, V2, V3. Thus:

[0050] - in the case of the double sliding door P (figures 1 to 3, 7), the first wing 30 of the The first support 3 can be fixed to the frame V12 of the first sliding leaf V1, preferably along the abutment side V21 of the first leaf VI, and the first wing 40 of the second support 4 can be fixed to the frame V22 of the second sliding leaf V2, preferably along the abutment side V21 of the second leaf V2,

[0051] - in the case of the simple sliding door P (figures 8 and 9), the first wing 40 of the The second support 4 can be fixed to the frame V32 of the single sliding leaf V3, preferably along the butt side V31 of the single leaf VL

[0052] In both cases, it is understood that each support 3, 4 equipped with the electrical The magnet(s) 1 or the counterplate(s) 2 extends along a vertical upright of the frame V12, V22. Furthermore, due to the high compactness of the electromagnetic locking device, it can be fixed to the frame V12, V22 without protruding into the infill.

[0053] In the case of the simple sliding door P, due to the extra thickness that the frame D can form and therefore a misalignment between the lateral surface of the frame D serving as a support for the first support 3 and the lateral surface of the single leaf V3 serving as a support for the second support 4, the present invention can provide a wedge which can be fixed on the single leaf V3 to compensate for this extra thickness or misalignment and allow the cooperation in the axis between the electromagnet(s) supported by the first support 3 fixed on the frame D and the counterplate(s) 2 supported by the second support 4 fixed on the single leaf V3.

[0054] If we refer more particularly to figures 4 to 7, we can see that the electromagnetic locking device according to the present invention can further comprise two covers (or covers) 5 suitable and intended each to be assembled respectively to one of the supports 3, 4, preferably by means of a quick assembly, for example a snap-fit ​​and / or snap-fit ​​assembly. The hoods 5 can preferably be identical in order to reduce manufacturing costs and are therefore adapted to be able to be fixed on either of the supports 3, 4. For this purpose, each support 3, 4 can have two longitudinal assembly edges 300, 311, 400, 410, namely a first assembly edge 300, 400 and a second assembly edge 311, 410 and each hood 5 can have three longitudinal assembly edges 50, 51, 52, namely a first assembly edge 50, a second assembly edge 51 and a third assembly edge 52.Preferably, the first assembly edge 300, 400 of each support 3, 4 can be formed in the end edge of its first wing 30, 40, for example by being formed by a notch, cutout or groove made in the end edge of its first wing 30, 40. Preferably, the second assembly edge 311, 410 of each support 3, 4 can be formed in the end edge of its second wing 31, 41, for example by a notch, cutout or groove made in the end edge of its second wing 31, 41.

[0055] In such a hood 5 adapted to be fixed on either of the two supports 3, 4:

[0056] - the first assembly edge 50 is suitable and intended to be assembled (or joined), of preferably by snap-fit ​​and / or interlocking, at the first assembly edge 300, 400 of each support 3, 4 ([Fig.4]). Figures 5 to 7 show the assembled state.

[0057] - the second assembly edge 51 is suitable and intended to be assembled (or joined), of preferably by snap-fit ​​and / or snap-fit, at the second assembly edge 311 of the first support 3. Figures 5 to 7 show the assembled state.

[0058] - and the third assembly edge 52 is suitable and intended to be assembled, from preferably by snap-fit ​​and / or snap-fit, at the second assembly edge 410 of the second support 4. Figures 5 to 7 show the assembled state.

[0059] In figures 5 and 7, the second T-shaped support 4 can be seen assembled to one of the covers 5, which are generally L-shaped in cross-section. More particularly, it can be seen that the first assembly edge 400, preferably in the form of a longitudinal groove, of the support 4 is assembled (or joined) to the first assembly edge 50, preferably in the form of a longitudinal rib, of the cover 5, and that the second assembly edge 410, preferably in the form of a longitudinal groove, of the support 4 is assembled (or joined) to the third assembly edge 52, preferably in the form of a longitudinal rib, of the cover 5. The assembly can thus be achieved by fitting and / or snapping each rib 50, 52 into the corresponding groove 400, 410.

[0060] In Figures 6 and 7, the first L-shaped support 3 can be seen assembled to the other hood 5, which is also L-shaped. More particularly, it can be seen that the first assembly edge 300, preferably in the form of a longitudinal groove, of the support 3 is assembled (or joined) to the first assembly edge 50, preferably in the form of a longitudinal rib, of the hood 5, and that the second assembly edge 311, preferably in the form of a longitudinal groove, of the support 3 is assembled (or joined) to the second assembly edge 51, preferably in the form of a longitudinal rib, of the hood 5. The assembly can thus be achieved by fitting and / or snapping each rib 50, 51 into the corresponding groove 300, 311.

[0061] In the assembled state of the hoods 5 with the supports 3, 4, it can be seen on the [Fig.7] that the hood 5 and the first support 3 define between them an internal space containing the electromagnet 1 (or the electromagnets 1) which protrude, in particular by its attraction face 10, from the attraction opening 310 (or the attraction openings 310) drilled in the second wing 31 of the support 3.

[0062] It can also be seen, in particular on [Fig.7], that the hood 5 assembled to the second support 4 can define between them a front opening for receiving the plywood or plywood 2. This front opening is oriented towards or is opposite or facing the attraction opening 310 or one of the attraction openings 310.

[0063] The present invention may also provide, for each hood 5, two end caps 6 for closing the two open ends after each hood 5 has been assembled onto the corresponding support 3, 4. Such end caps 6 also allow, by means of a fastening, for example by means of screws 7, the creation of an additional connection between the hood 5 and the support 3, 4, thereby reinforcing their assembly.

[0064] The plywood or each plywood 2 can be fixed, for example by screwing with a screw 20, the head of which presses against the plywood 2 by being screwed into the second wing 41 of the support 4 or, as can be seen in [Fig.7], into a nut 8 tightened against the rear face of the second wing 41 through which the screw 20 passes. This type of fixing by screwing or tightening the plywood is well known to those skilled in the art.

[0065] The electromagnet or each electromagnet 1 can be fixed by screwing by means of screws 11 screwed into the second wing 31 of the first support 3, for example on either side of the or one of the attraction opening(s) 310 (figures 4 and 7).

[0066] The electromagnet or each electromagnet 1 may have, on the side of its attraction face 10, at both ends, a shoulder 12 allowing the part of the electromagnet 1 having the attraction face 10 to be fitted into the attraction opening 310, preferably so that the attraction face 10 protrudes from the plane of the opening 310 (see in particular [Fig. 4]). The shoulders 12 form a stop defining the depth of the fit and therefore the position of the attraction face 10 relative to the attraction opening 310.

[0067] In the case of the single sliding door P, the first support 3 can be fixed to the frame D by means of screws screwed into a surface of the frame D. In the case of the double sliding door P, the first support 3 can be fixed to the first leaf V1 by means of screws 9 screwed into a surface of the first leaf VI, or, where applicable, into the frame V12 of the first leaf VI ([Fig. 7]). In the case of the double ([Fig. 7]) or single sliding door P, the second support 4 can be fixed to the single leaf V3 or the second leaf V2 by means of screws 9 screwed into a surface of the single leaf V3 or the second leaf V2, or, where applicable, into the frame V32 of the single leaf V3 or the frame V22 of the second leaf V2 ([Fig. 7]). The screws 9 are only shown or visible in [Fig. 7].

[0068] Preferably, each hood 5 can be a straight profile, preferably metallic, having an overall L-shaped cross-section. The end edges of the two arms of the L of each hood 5 can then form the first and second assembly edges 50, 51, respectively. The first and second assembly edges 50, 51 can each be formed, for example, as seen previously, by a rib formed in the corresponding end edge. The third assembly edge 52 can be formed by a rib formed in the inner face of one of the arms of the L, preferably the arm of the L containing the second assembly edge 51. The ribs can extend parallel to each other.Each rib forming a first, second or third assembly edge 50, 51, 52 of the hood 5 and being suitable and intended to be fitted, preferably by snap-fitting, into the corresponding groove, notch or cutout forming the first or second assembly edge 300, 311, 400, 410 of the support 3, 4. The fitting, which may be by snap-fitting, is preferably reversible so as to be able to remove each . cover 5 of support 3, 4 in particular to be able to access the electromagnet 1 or the plywood 2 for the purpose of their maintenance.

[0069] Finally, if we refer again to figures 1 to 3, we can see that a hood 5, preferably the hood 5 assembled on the second support 4 supporting the plywood or plywood 2, can include a notch or cutout 54 allowing to create a handle to open the single or double sliding door P, that is to say to move manually by sliding in opening or closing the relevant sliding leaf VI, V2.

[0070] Note that, in the case of a simple sliding door, the first support 3 can be provided, in an alternative not illustrated with an equivalent immobilizing function, to support the electromagnet 1 on the single sliding leaf V3 and the second support 4 can be provided to support the plywood 2 on the frame D. The first wing 30 of the first support 3 can then be suitable and intended to be fixed, or (in the mounted state) be fixed, on the single sliding leaf V3 and the first wing 40 of the second support 4 can then be suitable and intended to be fixed, or (in the mounted state) be fixed, on the frame D.

[0071] The present invention thus makes it possible to obtain a compact electromagnetic locking device for single or double sliding doors. It also facilitates mounting on single or double sliding doors and solves the problems of mechanical or electric locks currently used on sliding doors, thanks to reduced wear due to the use of electromagnetic technology, which does not use moving parts such as a bolt and its actuation mechanism.

[0072] Of course, the invention is not limited to the embodiment described and shown in the accompanying drawings. Modifications remain possible, particularly with regard to the composition of the various elements or by substitution of technical equivalents, without departing from the scope of protection of the invention.
