Description

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

[0001] The present invention relates to the field of doors, in particular sliding doors, and more particularly 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] Hereinafter, the term "door" will be understood to mean a fixed part (frame, frame, door jamb 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 the door, of closing the passage opening of the door by opposing the passage. Such an opening is made in a wall or partition in a building or structure.

[0003] Electromagnetic locks are already known for immobilizing the door leaf in the closed position. These electromagnetic locks are most often mounted on swing doors, i.e. doors whose leaf is pivotally mounted on the fixed part of the door using a hinge system.

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

[0005] The mounting of electromagnetic locks on doors is carried out by means of two supports consisting of rectilinear metal profiles, namely a plywood support and a suction cup support. For reasons of space and power supply to the electromagnet, the suction cup 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 leaf. These supports are integrated into the frame (or chassis) of the leaf or in the fixed part of the door or are attached by being fixed to the frame (or chassis) of the leaf or to the fixed part of the door.

[0006] These electromagnetic locks are less commonly fitted to sliding doors. In this type of door, we know sliding doors, called double sliding doors, comprising two sliding leaves extending in the same plane and moving away from or towards each other when they are moved in opening or closing. We also know single sliding doors comprising a single sliding leaf moving away from or towards a frame upright. These sliding doors are generally equipped with a mechanical or electric lock. However, these mechanical or electric locks present problems of wear, unlocking or personal safety, or require the use of a key.Furthermore, especially in the case of double sliding doors, the upper part of the door, i.e. its fixed part, has a reduced surface area which does not allow, or makes it difficult to fix, the supports for the electromagnet and the plywood.

[0007] Document US8585105 discloses such an electromagnetic lock fitted to a double sliding door, making it possible to solve the problems of sliding doors with an electric or mechanical lock, i.e. a lock comprising a bolt moved under the effect of a manual or electric control. The sliding door of this document comprises for this purpose a locking assembly comprising an electromagnetic lock. Two supports, of L-shaped section, respectively support the electromagnet and the plywood of the electromagnetic lock. Each L-shaped support is fixed to the upper or lower part of one of the two leaves. The electromagnet and the plywood are fixed on the back (external face) of the vertical branch of the L.

[0008] However, a sliding door equipped with a locking assembly of the type disclosed in document US8585105 poses a problem of compactness which does not allow in particular mounting on a reduced support surface, for example a support surface formed by a surface of the frame surrounding the glazing of a glazed leaf. Indeed, this frame is generally narrow because users are increasingly seeking to gain in brightness by using leaves with the largest possible glazed surface. The surface of the frame which can serve as support outside the glazed surface is therefore correspondingly reduced.

[0009] The present invention aims to overcome these drawbacks by proposing an electromagnetic lock device for a double or single sliding door which is very compact, while offering easy mounting on a double or single sliding door and making it possible to solve the problems of mechanical or electrical locks fitted to current sliding doors.

[0010] The electromagnetic lock 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 movable between an open position and a closed position of the double sliding door, the electromagnetic lock 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 for supporting the electromagnet on the first sliding leaf and a second support for supporting the plywood on the second sliding leaf, is characterized in that the first and second supports are rectilinear profiles each having at least two wings, namely a first wing and a second wing, forming a right angle between them,the first wing of the first support being suitable and intended to be fixed on the first sliding leaf and the first wing of the second support being suitable and intended to be fixed on the second sliding leaf and in that the second wing of the first support is pierced with at least one opening, called an attraction opening, allowing cooperation between the attraction face of the electromagnet or at least one of the electromagnets fixed on the first support and the or at least one of the counterplate(s) fixed on the second support.

[0011] The electromagnetic lock 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 lock 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 rectilinear profiles each having at least two wings, namely a first wing and a second wing, forming a right angle between them,the first wing of the first support being suitable and intended to be fixed on the frame and the first wing of the second support being suitable and intended to be fixed on the single sliding leaf and in that the second wing of the first support is pierced with at least one opening, called an attraction opening, allowing cooperation between the attraction face of the electromagnet or at least one of the electromagnets fixed on the first support and the or at least one of the counterplate(s) fixed on the second support.

[0012] The present invention also relates to a double sliding door equipped with an electromagnetic lock 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 opening position and a closing position of the double sliding door, characterized in that the electromagnetic lock device consists of an electromagnetic lock 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 also relates to a simple sliding door equipped with an electromagnetic lock 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 lock device consists of an electromagnetic lock device according to the present invention and in that the first wing of the first support is fixed to the frame and the first wing of the second support is fixed to the single sliding leaf.

[0014] The invention will be better understood from the following description, which relates to a preferred embodiment, given by way of non-limiting example, and explained with reference to the appended schematic drawings, in which:

[0021] [Fig.7] is a partial sectional view of the sliding door shown in [Fig.l] at the level of the electromagnetic lock device and in the closed state of the sliding door,

[0022] [Fig.8] is a perspective view of a single sliding door according to the present invention equipped with an electromagnetic lock device according to the present invention, in an intermediate opening position of the door,

[0023] [Fig.9] shows the single sliding door shown in [Fig.8] in another orientation.

[0024] Figures 1 to 3 attached show a double sliding door P, according to the present invention, equipped with an electromagnetic lock 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] The attached figures 8 and 9 show a simple sliding door equipped with an electromagnetic lock 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 lock device, according to the present invention, equipping the sliding or double door P shown in Figures 1, 2, 3, 8, 9 comprises two electromagnets 1 and two plywoods 2 each capable of cooperating with one of the two electromagnets 1. Figures 4 to 6 show an electromagnetic lock device, according to the present invention, comprising a single electromagnet 1 and a single plywood 2 capable of cooperating with the electromagnet. Such an electromagnetic lock 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 plywoods 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 the opening 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 term "frame D" refers to the fixed part of the single or double sliding door P. Such a fixed part is also known, for example, under the names of a fixed frame, a door frame or woodwork. Such a frame D may comprise two vertical uprights and a crosspiece connecting the two uprights at their end or upper part.

[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 a partition M, in particular in a building or an edifice (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 not, solid or openwork. The panel may be of any construction, or be made from any material, and may have specific qualities, for example fire-resistant. Such a panel, as also described below, may comprise a peripheral frame VI2, V22, V32 entirely surrounding or partially surrounding the panel. entially a filling. Each leaf VI, V2, V3 is movable by sliding laterally (or parallel) relative 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 (case of figures 1 and 2), in particular 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 on the partition or the wall M, in particular in an area located above the opening O of the door P.

[0031] The electromagnetic lock device, according to the present invention, equipping 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 lock device, according to the present invention, equipping 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 double or single sliding door P, comprises:

[0033] - at least one electromagnet 1,

[0034] - at least one plywood 2 capable and intended to cooperate by electromagnetic attraction magnetic 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 illustrated) or the two sliding leaves VI, V2 (case of the double sliding door P illustrated in figures 1 to 3), and

[0035] - in the case of the simple sliding door P, a first support 3 for supporting 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 for supporting 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 may be in the form of a generally rectangular parallelepiped, one of the faces of which forms the attraction face 10 capable and intended to cooperate by electromagnetic attraction with the plywood 2. The electromagnet 1 (or suction cup) comprises a functional part capable of producing an electromagnetic field when supplied with electric current. The electric current is conveyed via electric cables E. Electric 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 in detail 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 profiles, preferably metal, rectilinear, each having at least two wings 30, 31, 40, 41, namely a first wing 30, 40 and a second wing 31, 41, forming a right angle between them. A right angle is understood to mean an angle equal to 90° or approximately equal to 90°. In addition, the second wing 31 of the first support 3 is pierced with at least one opening 310, called an attraction opening 310, allowing cooperation between the electromagnet 1 or at least one of the electromagnets 1 fixed to the first support 3 and the or one of the counterplate(s) 2 fixed 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 on 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 on the second sliding leaf V2. It is understood that in the mounted state of the electromagnetic lock device on / in the double sliding door P, the first wing 30 of the first support 3 is fixed on the first sliding leaf V1 and the first wing 40 of the second support 4 is fixed on the second sliding leaf V2.

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

[0041] The or each electromagnet 1 is fixed on the first support 3, preferably on the second wing 31 of the first support 3. The 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 in [Fig.7], the second wing 31, 41 of each support 3, 4 can extend perpendicularly 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 large vertical sides V10, V20, V30 parallel (to each other) and two small vertical sides V11, V21, V31 perpendicular to the large sides V10, V20, V30. It is understood that each large vertical side V10, V20, V30 forms a side or, in other words, a lateral face, of the leaf VI, V2, V3 which 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 edge (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 small sides V11, V21, called the abutting side V11, V21, of each sliding leaf VI, V2 comes or is capable of coming to abut with the abutting side V11, 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 abutting side VI1, V21 is also known as the front side of the sliding leaf. The first support 3 can then be fixed on one of the large sides V10, called the first large side V10, of the first sliding leaf VI by extending (vertically) along (partially or entirely) its abutting side V11. Furthermore, 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 abutting side V21 of the second sliding leaf V2. The second support 4, which has an elongated and rectilinear shape, then extends parallel to the abutting side V21. Similarly, the or each electromagnet 1 fixed on the first support 3 extends parallel to the abutting side V11 of the first leaf VI (and also to the abutting side V21 of the second leaf V2) and the or each plywood 2 fixed on the second support 4 extends parallel to the abutting side V21 of the second leaf V2 (and also to the abutting side VI1 of the first leaf VI).

[0045] In the case of a single sliding door P, as can be seen in Figures 8 and 9, one of the small sides V31, called the abutment side V31, of the single sliding leaf V3 comes or is capable of coming to abut with the frame D, that is to say with an upright of the frame D, in the closed position of the single sliding door. The second support 4 can then be fixed on one of the large sides V30 of the single sliding leaf V3 by extending along (partially or entirely) its abutment side V32. The second support 4, which has an elongated and rectilinear shape, then extends parallel to the abutment side. Similarly, the or each plywood 2 extends parallel to the abutment 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 on (or in) the first support 3 by occupying a space delimited between the first wing 30 and the second wing 31 of the first support 3 on the side of the right angle formed by the latter. This characteristic makes it possible to confer great compactness to the device since the electromagnet 1 is inscribed in some way entirely or essentially in 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 on the first support 3 in a position where its attraction face 10 is located in (not illustrated) 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 characteristic makes it possible to ensure good contact between the attraction face 10 and the plywood 2 cooperating with the latter.The present invention could also provide, in a form not illustrated, that the attraction face 10 is set back from the attraction opening 310 but this embodiment is more complex to produce and requires that the opening allows the plywood 2 to be received or to be crossed by the latter to ensure its contact with the attraction face 10 located set back.

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

[0049] It can be seen in Figures 1 to 3, 7, 8 and 9 that each sliding leaf VI, V2, V3 of the double or single sliding door P can comprise a frame V12, V22, V32 completely or partially surrounding (on the periphery) 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 mentioned above constituting the leaf V12, V22, V32. The filling V13, V23, V33 can be, for example, but not limited to, a glazing, that is to say at least one plate of transparent material. It is then understood that the electromagnetic lock device, due to its great compactness, can easily be fixed on 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 first support 3 can be fixed on the frame V12 of the first sliding leaf V1, preferably along the abutting side V21 of the first leaf VI and the first wing 40 of the second support 4 can be fixed on the frame V22 of the second sliding leaf V2, preferably along the abutting side V21 of the second leaf V2,

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

[0052] In these two cases, it is understood that each support 3, 4 equipped with the elec magnet(s) 1 or counterplate(s) 2 extends along a vertical upright of frame V12, V22. Furthermore, due to the high compactness of the electromagnetic lock device, it can be fixed to frame V12, V22 without protruding towards the filling.

[0053] In the case of the single sliding door P, due to the excess thickness that the frame D can form and therefore an offset between the lateral surface of the frame D serving as support for the first support 3 and the lateral surface of the single leaf V3 serving as support for the second support 4, the present invention can provide a shim that can be fixed on the single leaf V3 to compensate for this excess thickness or this offset and allow 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 lock device according to the present invention can further comprise two covers (or covers) 5 each suitable and intended to be assembled respectively to one of the supports 3, 4, preferably by means of a rapid assembly, for example an assembly by snap-fastening and / or interlocking. The covers 5 may preferably be identical in order to reduce manufacturing costs and consequently be adapted to be able to be fixed on one or other of the supports 3, 4. For this purpose, each support 3, 4 may comprise two longitudinal assembly edges 300, 311, 400, 410, namely a first assembly edge 300, 400 and a second assembly edge 311, 410 and each cover 5 may comprise 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 may be formed in the end edge of its first wing 30, 40, for example by being formed by a notch, a cutout or a groove made in the end edge of its first wing 30, 40. Preferably, the second assembly edge 311, 410 of each support 3, 4 may be formed in the end edge of its second wing 31, 41, for example by a notch, a cutout or a groove made in the end edge of its second wing 31, 41.

[0055] In such a cover 5 adapted to be fixed on one or the other of the two supports 3, 4:

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

[0057] - the second assembly edge 51 is suitable and intended to be assembled (or joined), preferably by snap-fastening and / or interlocking, to the second assembly edge 311 of the first support 3. In Figures 5 to 7, the assembled state can be seen.

[0058] - and the third assembly edge 52 is suitable and intended to be assembled, preferably by snap-fastening and / or interlocking, to the second assembly edge 410 of the second support 4. In Figures 5 to 7, the assembled state can be seen.

[0059] In Figures 5 and 7, the second support 4 of T-shaped section can be seen assembled to one of the covers 5 of generally L-shaped 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 carried out by fitting and / or snap-fastening each rib 50, 52 into the corresponding groove 400, 410.

[0060] In Figures 6 and 7, the first support 3 of L-shaped section can be seen assembled to the other cover 5 of generally L-shaped section. 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 cover 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 cover 5. The assembly can thus be carried out by fitting and / or snap-fastening each rib 50, 51 into the corresponding groove 300, 311.

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

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

[0063] The present invention may also provide for each cover 5, two end covers 6 making it possible to close the two open ends respectively after the assembly of each cover 5 on the corresponding support 3, 4. Such end covers 6 also make it possible, thanks to a fixing, for example by means of screws 7, to create an additional connection between the cover 5 and the support 3, 4 making it possible to reinforce their assembly.

[0064] The or each plywood 2 can be fixed, for example by screwing using a screw 20, the screw head of which presses against the plywood 2 while 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 or each electromagnet 1 can be fixed by screwing using 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 or each electromagnet 1 may comprise, on the side of its attraction face 10, at its two ends, a shoulder 12 making it possible to fit into the attraction opening 310 the part of the electromagnet 1 comprising the attraction face 10 in 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 fitting 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, where appropriate of 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 in a surface of the single leaf V3 or the second leaf V2, where appropriate of the frame V32 of the single leaf V3 or of the frame V22 of the second leaf V2 ([Fig.7]). The screws 9 are only shown or visible in [Fig.7].

[0068] Preferably, each cover 5 may be a rectilinear profile, preferably metallic, having a generally L-shaped section. The end edges of the two branches of the L of each cover 5 may then respectively form the first and second assembly edges 50, 51. The first and second assembly edges 50, 51 may each be formed, for example, as seen previously, by a rib made in the corresponding end edge. The third assembly edge 52 may be formed by a rib formed in the internal face of one of the branches of the L, preferably of the branch of the L comprising the second assembly edge 51. The ribs may extend parallel to each other.Each rib forming a first, second or third assembly edge 50, 51, 52 of the cover 5 and being suitable and intended to be fitted, preferably by snap-fitting, in 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 in order 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 maintenance.

[0069] Finally, if we refer again to figures 1 to 3, we can see that a cover 5, preferably the cover 5 assembled on the second support 4 supporting the plywood or plywoods 2, can comprise a notch or a cutout 54 making it possible to create a handle for opening the single or double sliding door P, that is to say for manually moving by sliding in opening or closing the sliding leaf VI, V2 concerned.

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

[0071] The present invention thus makes it possible to obtain an electromagnetic lock device for a double or single sliding door which is very compact. It also makes it easier to mount it on the double or single sliding door and to solve the problems of mechanical or electrical locks fitted to current sliding doors, thanks to reduced wear due to the use of electromagnetic technology which does not use parts such as a moving lock and its actuating means.

[0072] Of course, the invention is not limited to the embodiment described and shown in the attached drawings. Modifications remain possible, in particular from the point of view of the constitution of the various elements or by substitution of technical equivalents, without departing from the scope of protection of the invention.
