A cette fin, une serrure électromécanique telle que définie dans l'entrée en matière est caractérisée en ce qu'elle comprend des moyens mécaniques solidaires du noyau et coopérant à glissement avec le pêne pour condamner un recul du pêne avant le retrait complet de la tête du pêne de la. gâche lorsque la bobine est alimentée et pour permettre la translation libre du pêne lorsque la bobine n'est plus alimentée, la source fournissant à la bobine un courant juste nécessaire pour maintenir le noyau dans la bobine et insuffisant pour attirer le noyau dans la bobine.To this end, an electromechanical lock as defined in the entry into material is characterized in that it comprises mechanical means integral with the core and cooperating with sliding with the bolt to condemn a retraction of the bolt before the complete removal of the head of the bolt of the. keeper when the coil is supplied and to allow free translation of the bolt when the coil is no longer supplied, the source supplying the coil with a current just necessary to maintain the core in the coil and insufficient to attract the core in the coil.

Selon une autre caractéristique de l'invention, le noyau coulisse perpendiculairement au pêne et les moyens mécaniques comprennent un ergot solidaire du noyau, glissant par gravité sur une encoche en vé du chant supérieur du pêne lorsque la bobine n'est pas alimentée et le pêne recule, et un piston rappelé vers le pêne par un ressort inclus dans une chambre solidaire du noyau, ledit piston étant engagé dans une seconde entaille du pêne lorsque le noyau est maintenu dans la bobine par connexion à la source et par l'ergot sur le chant supérieur du pêne au début du recul du pêne pour condamner la serrure, et ledit piston étant dégagé de ladite seconde entaille après que la bobine soit déconnectée de la source et que l'ergot ait glissé sur l'encoche en vé et ait franchi le fond de l'encoche en vé lorsque le pêne recule à la position d'ouverture.According to another characteristic of the invention, the core slides perpendicular to the bolt and the mechanical means comprise a lug secured to the core, sliding by gravity on a vee notch in the upper edge of the bolt when the reel is not energized and the bolt moves back, and a piston returned to the bolt by a spring included in a chamber secured to the core, said piston being engaged in a second notch in the bolt when the core is held in the coil by connection to the source and by the lug on the upper edge of the bolt at the start of the retraction of the bolt to lock the lock, and said piston being released from said second notch after the coil is disconnected from the source and the lug has slipped over the vee notch and has crossed the bottom of the vee notch when the bolt moves back to the open position.

Selon un autre aspect de l'invention, la consommation en courant de l'électro-aimant peut être encore réduite grâce à des moyens, tels qu'un contacteur, pour déconnecter la bobine de la source pendant une faible course du pêne à partir de la position extrême d'avance du pêne et pour connecter la bobine à la source pendant le reste de la course du pêne en vue de condamner la serrure lorsque la source est connectée. Selon une réalisation préférée, la serrure comprend un ressort rappelant en butée le bras du fouillot suivant la direction d'avance du pêne, et les moyens pour connecter et déconnecter comprennent un contacteur en série entre une borne de la bobine et une borne de la source, et un levier fixé au fouillot qui est appliqué contre le contact mobile du contacteur sous l'action du ressort de rappel du fouillot pour ouvrir le contacteur pendant la faible course du pêne à partir de la position extrême d'avance du pêne et qui est désengagé du contact mobile par poussée du bras du fouillot exercée par la première entaille du pêne ou par rotation du bras du fouillot dans la première entaille sans recul du pêne pour fermer le contacteur pendant le reste de la course du pêne.According to another aspect of the invention, the current consumption of the electromagnet can be further reduced by means, such as a contactor, for disconnecting the coil from the source during a short stroke of the bolt from the extreme position of advance of the bolt and to connect the coil to the source during the rest of the stroke of the bolt in order to lock the lock when the source is connected. According to a preferred embodiment, the lock comprises a spring restoring the arm of the follower in the direction of advance of the bolt, and the means for connecting and disconnecting comprise a contactor in series between a terminal of the coil and a terminal of the source , and a lever fixed to the follower which is applied against the movable contact of the contactor under the action of the follower return spring to open the contactor during the short stroke of the bolt from the extreme forward position of the bolt and which is disengaged from the movable contact by thrust of the follower arm exerted by the first notch of the bolt or by rotation of the follower arm in the first notch without recoil of the bolt to close the contactor during the rest of the stroke of the bolt.

Les modes de réalisation de serrure décrits ci-après concernent une serrure électromécanique encloisonnée, c'est-à-dire posée en applique sur la face intérieure du battant d'une porte. Les éléments de la serrure sont montés pour obtenir une serrure en tirant à gauche ou en poussant à droite, bien que la serrure soit réversible comme on le verra dans la suite. Dans toutes les figures, les éléments sont vus de l'intérieur, le palastre et le foncet du coffre (non représenté) de la serrure étant respectivement tournés vers l'extérieur et vers l'intérieur par rapport à la porte.The lock embodiments described below relate to an enclosed electromechanical lock, that is to say posed on the inside of the leaf of a door leaf. The elements of the lock are mounted to obtain a lock by pulling on the left or pushing on the right, although the lock is reversible as will be seen below. In all the figures, the elements are seen from the inside, the palaster and the trunk (not shown) of the lock being respectively turned towards the outside and towards the inside with respect to the door.

La serrure électromécanique est particulièrement destinée à une porte de sas ou à une porte extérieure de bâtiment.The electromechanical lock is particularly intended for an airlock door or an exterior building door.

Le mécanisme électromécanique de la serrure comprend essentiellement un corps 1 de forme générale parallélépipédique, un pêne demi-tour horizontal 2, un électro-aimant 3, un fouillot de manoeuvre 4, et un dispositif de rappel à ressort 5 du pêne.The electromechanical mechanism of the lock essentially comprises a body 1 of generally parallelepiped shape, a horizontal latch bolt 2, an electromagnet 3, an actuating follower 4, and a spring return device 5 of the bolt.

Le corps 1 présente deux axes concourrants X'X et Y'Y. L'axe X'X est horizontal et définit la direction de coulissement du pêne 2. L'axe Y'Y est vertical et définit la direction de coulissement d'un noyau ferromagnétique vertical cylindrique 30 de l'électro-aimant 3.The body 1 has two concurrent axes X'X and Y'Y. The axis X'X is horizontal and defines the direction of sliding of the bolt 2. The axis Y'Y is vertical and defines the direction of sliding of a cylindrical vertical ferromagnetic core 30 of the electromagnet 3.

Le pêne 2 coulisse dans une glissière rectangulaire longitudinale 10 axée sur l'axe X'X et pratiquée. dans la face intérieure du corps 1. L'avant du pêne 2 comporte une tête 20 à biseau 21 tourné vers l'extérieur. La tête 20 est fixée au pêne par deux vis transversales 22. La queue du pêne est poussée vers l'avant, en direction de la gâche de la serrure, par le dispositif de rappel à ressort 5.The bolt 2 slides in a longitudinal rectangular slide 10 centered on the axis X'X and practiced. in the inner face of the body 1. The front of the bolt 2 has a head 20 with bevel 21 facing outwards. The head 20 is fixed to the bolt by two transverse screws 22. The tail of the bolt is pushed forward, in the direction of the keeper of the lock, by the spring return device 5.

Le dispositif 5 est constitué essentiellement par un ressort de compression 50 qui est maintenu coaxial à l'axe X'X au moyen de deux petits guides cylindriques avant 51 et arrière 52. Chaque guide 51, 52 possède un téton avant 510, 520 et un téton arrière 511, 521 de part et d'autre d'une collerette 512, 522. Les tétons 511 et 520 reçoivent les spires aux extrémités avant et arrière du ressort 50. Le téton avant 510 est logé dans un trou 230 dans le chant arrière vertical 23 du pêné.La collerette 511 est plaquée contre le chant 23 par le ressort 50 et peut venir en butée contre le chant arrière lIa du corps 1. Le téton arrière 521 est logé dans un trou 530 dans un côté 531 transversal vertical d'une équerre de réglage 53 contre lequel la collerette 511 est plaquée en permanence par le ressort 50. L'autre côté 532 de l'équerre 53 est fixé sur le palastre de la serrure d'une manière réglable afin d'ajuster convenablement la course de recul du pêne en fonction des positions relatives du corps 1 et de la gâche en vue de dégager la tête 20 de la gâche lors de l'ouverture de la porte. A cette fin, le côté 532 de l'équerre 53 est pourvue d'une lumière oblongue 533 le long de l'axe X'X, traversée par une ou deux vis 534 vissées dans des trous taraudés du palastre de la serrure.The device 5 essentially consists of a compression spring 50 which is kept coaxial with the axis X'X by means of two small cylindrical guides 51 and 52 at the rear 52. Each guide 51, 52 has a front stud 510, 520 and a rear stud 511, 521 on either side of a flange 512, 522. The studs 511 and 520 receive the turns at the front and rear ends of the spring 50. The front stud 510 is housed in a hole 230 in the rear edge vertical 23 of the bolt. The flange 511 is pressed against the edge 23 by the spring 50 and can come into abutment against the rear edge lIa of the body 1. The rear stud 521 is housed in a hole 530 in a vertical side 531 of an adjustment bracket 53 against which the flange 511 is permanently pressed by the spring 50. The other side 532 of the bracket 53 is fixed to the palastre of the lock in an adjustable manner in order to suitably adjust the stroke of retraction of the bolt as a function of the relative positions of the c orps 1 and the strike in order to release the head 20 from the strike when the door is opened. To this end, the side 532 of the bracket 53 is provided with an oblong slot 533 along the axis X'X, crossed by one or two screws 534 screwed into tapped holes in the palastre of the lock.

Le pêne 2 comporte également une encoche en vé 24 dans le chant longitudinal supérieur 25 du pêne, au niveau de l'axe YY, une petite entaille rectangulaire 26 dans le chant longitudinal inférieur 27 du pêne, au niveau de l'axe Y'Y, une longue entaille rectangulaire 28 dans le chant longitudinal inférieur 27 entre l'encoche 26 et le chant arrière 23, ainsi qu'un trou transversal horizontal 29 entre la tête 20 et l'encoche 24.The bolt 2 also includes a vee notch 24 in the upper longitudinal edge 25 of the bolt, at the level of the YY axis, a small rectangular notch 26 in the lower longitudinal edge 27 of the bolt, at the level of the axis Y'Y , a long rectangular cut 28 in the lower longitudinal edge 27 between the notch 26 and the rear edge 23, as well as a horizontal transverse hole 29 between the head 20 and the notch 24.

Le boîtier de l'électro-aimant 3 est fixé sur le palastre de la serrure au-dessus du corps 1 afin que le noyau ferromagnétique 30 soit coaxial à l'axe Y'Y. La majeure partie du noyau 30 plonge dans la bobine 31 de l'électro-aimant.La bobine a deux bornes 32 saillantes du boîtier et reliées à une source d'alimentation électrique éloignée ou non de la serrure et connectée à distance manuellement ou automatiquement. L'extrémité inférieure du noyau 30 pénètre dans un alésage 330 d'un boisseau cylindrique vertical 33 coaxial à l'axe Y'Y et est fixée à l'extrémité supérieure du boisseau par une goupille cylindrique 34 diamétrale au boisseau et parallèle à l'axe X'X sans que ce positionnement soit obligatoire. La goupille 34 n'est destinée qu'à solidariser le noyau 30 et le boisseau 33. Au-dessous de la base inférieure du noyau 30 est pratiquée une lumière oblongue verticale 331 dans le boisseau 33. La lumière 331 est diamétrale et centrée de part et d'autre du plan X'X-Y'Y. Elle est traversée par le pêne au niveau des encoches 24 et 26. La largeur de la lumière 331 est sensiblement supérieure à l'épaisseur du pêne 2. Cependant, la hauteur de la lumière 331 est plus grande que la hauteur du pêne 2. En partie supérieure de la lumière 331 et sous la base inférieure du noyau 30 est logé un ergot cylindrique 35 dans un trou diamétral 332 du boisseau 31 perpendiculaire au plan X'X-Y'Y. L'ergot 35 est destiné à glisser sur le chant longitudinal supérieur 25 et sur les côtés avant et arrière, 240 et 241, de l'encoche en vé 24 du pêne 2.The case of the electromagnet 3 is fixed on the palastre of the lock above the body 1 so that the ferromagnetic core 30 is coaxial with the axis Y'Y. Most of the core 30 is immersed in the coil 31 of the electromagnet. The coil has two terminals 32 projecting from the housing and connected to a power source remote or not from the lock and remotely connected manually or automatically. The lower end of the core 30 penetrates into a bore 330 of a vertical cylindrical bushel 33 coaxial with the axis Y'Y and is fixed to the upper end of the bushel by a cylindrical pin 34 diametrical to the bushel and parallel to the X'X axis without this positioning being mandatory. The pin 34 is only intended to secure the core 30 and the plug 33. Below the lower base of the core 30 is made an oblong vertical light 331 in the plug 33. The light 331 is diametrical and centered on the side and on the other side of the X'X-Y'Y plane. It is crossed by the bolt at the notches 24 and 26. The width of the light 331 is substantially greater than the thickness of the bolt 2. However, the height of the light 331 is greater than the height of the bolt 2. In upper part of the lumen 331 and under the lower base of the core 30 is housed a cylindrical lug 35 in a diametrical hole 332 of the plug 31 perpendicular to the plane X'X-Y'Y. The lug 35 is intended to slide on the upper longitudinal edge 25 and on the front and rear sides, 240 and 241, of the vee notch 24 of the bolt 2.

Le boisseau 33 coulisse dans deux alésages 12 et 12' coaxiaux à l'axe Y'Y et pratiqués dans le corps 1 de part et d'autre de la glissière 10. L'alésage supérieur 12 reçoit la partie supérieure du boisseau contenant l'extrémité inférieure du noyau 30 et l'ergot 35. L'alésage inférieur 12' reçoit la partie inférieure du boisseau en-dessous de la lumière 331. Dans la partie inférieure du boisseau 33 est pratiquée une chambre cylindrique 334 coaxiale à l'axe Y'Y. La chambre 334 contient un ressort de compression 36 qui pousse vers le fond supérieur de la chambre une embase 370 d'un piston 37 ayant un téton 371 débouchant dans la lumière 331 du boisseau. La base inférieure du ressort 36 est maintenue dans la chambre 334 au moyen d'un anneau élastique ouvert 38 introduit dans une gorge annulaire en partie inférieure de la chambre. Le téton 371 du piston 37 est propre à s'encastrer dans la petite entaille rectangulaire 26 du pêne ayant une longueur plus grande que le diamètre du téton, et à glisser contre le chant longitudinal inférieur 27 du pêne à l'avant de l'encoche 26.The plug 33 slides in two bores 12 and 12 'coaxial with the axis Y'Y and formed in the body 1 on either side of the slide 10. The upper bore 12 receives the upper part of the plug containing the lower end of the core 30 and the lug 35. The lower bore 12 'receives the lower part of the plug below the light 331. In the lower part of the plug 33 is formed a cylindrical chamber 334 coaxial with the axis Y 'Y. The chamber 334 contains a compression spring 36 which pushes towards the upper bottom of the chamber a base 370 of a piston 37 having a stud 371 opening into the lumen 331 of the plug. The lower base of the spring 36 is held in the chamber 334 by means of an open elastic ring 38 introduced into an annular groove in the lower part of the chamber. The pin 371 of the piston 37 is suitable for fitting into the small notch rectangular 26 of the bolt having a length greater than the diameter of the stud, and to slide against the lower longitudinal edge 27 of the bolt at the front of the notch 26.

Le fouillot 4 est une pièce dont le corps est cylindrique, pouvant tourner entre le palastre et le foncet de la serrure dans un alésage 13a du corps 1 pratiqué perpendiculairement au plan X'X-Y'Y et en-dessous de l'encoche arrière 28 du pêne 2. Sous le pêne, le corps 1 comporte entre l'alésage 12' et le chant arrière 11a, une grande encoche sensiblement en vé 14a ayant un fond terminé par une section de l'alésage 13a sous la glissière 10. L'encoche 14a reçoit un bras ou came 40 sensiblement curviligne à la périphérie centrale du fouillot 4. Le bras 40 est destiné à transformer un mouvement de rotation du bouton ou de la poignée de la serrure ayant une tige carrée pénétrant dans un trou central carré 41 du fouillot 4 en un mouvement de translation du pêne demi-tour 2 par l'intermédiaire de l'engagement du sommet du bras 40 dans la grande entaille 28 de la queue du pêne. Au-dessus du bras 40, le fouillot 4 peut être entouré par un ressort à deux spires 42 ayant deux brins 420 et 421 repliés horizontalement contre la base du côté arrière du bras 40 et le côté arrière de l'encoche 14a. Le ressort 42 rappelle ainsi le bras 40 du fouillot vers l'avant, contre le côté avant 140a de l'encoche en vé arrière 14a lorsque la poignée de la serrure est relâchée.The follower 4 is a part whose body is cylindrical, which can rotate between the palaster and the lock of the lock in a bore 13a of the body 1 formed perpendicular to the plane X'X-Y'Y and below the rear notch 28 of the bolt 2. Under the bolt, the body 1 comprises between the bore 12 'and the rear edge 11a, a large notch substantially in vee 14a having a bottom terminated by a section of the bore 13a under the slide 10. L the notch 14a receives a substantially curvilinear arm or cam 40 at the central periphery of the follower 4. The arm 40 is intended to transform a rotary movement of the button or of the handle of the lock having a square rod penetrating into a central square hole 41 of the follower 4 in a translational movement of the latch bolt 2 through the engagement of the top of the arm 40 in the large notch 28 of the tail of the bolt. Above the arm 40, the follower 4 may be surrounded by a spring with two turns 42 having two strands 420 and 421 folded horizontally against the base of the rear side of the arm 40 and the rear side of the notch 14a. The spring 42 thus recalls the arm 40 of the follower forwards, against the front side 140a of the rear vee notch 14a when the handle of the lock is released.

La réalisation illustrée de la serrure selon l'invention concerne une serrure à trois points qui est également réversible. Pour ces raisons, le corps 1 est symétrique par rapport à l'axe Y'Y.The illustrated embodiment of the lock according to the invention relates to a three-point lock which is also reversible. For these reasons, the body 1 is symmetrical with respect to the axis Y'Y.

Les deux autres points de fermeture supplémentaires de la serrure sont obtenus au moyen d'une tringle verticale supérieure 6s et d'une tringle verticale inférieure 6i. Les tringles 6i et 6s coulissent dans une glissière rectangulaire 15b pratiquée dans la face extérieure du corps 1 contre le palastre de la serrure, le long d'un axe vertical disposé à une distance de l'axe Y'Y égale à la distance entre l'axe de rotation horizontal du fouillot 4 et l'axe Y'Y. La portion inférieure de la queue de la tringle 6s et la portion supérieure de la queue de la tringle 6i sont pourvues de lumières croisées symétriquement par rapport à l'axe X'X et superposées dans la glissière 15b. Les lumières 60s et 60i reçoivent un ergot 61 traversant le trou transversal 29 du pêne et une lumière oblongue 16b dans le fond de la glissière 10 du corps 1. La lumière 16b horizontale est ainsi bissectrice de l'angle formé par les lumières 60s et 60i des deux tringles. Dans ces conditions, le recul du pêne 2 pour l'ouverture de la porte produit un recul vers le bas de la tringle 6s et un recul vers le haut de la tringle 6i, et l'avance du pêne 2 pour la fermeture de la porte produit une avance vers le haut de la tringle 6s et une avance vers le bas de la tringle 6i. Un dispositif de rappel élastique sous la forme d'un ressort vertical de traction 62 peut être également prévu pour rappeler les tringles 6s et 6i en position de fermeture, le rappel par le ressort 62 complétant le rappel par le ressort 50 du pêne 2. L'un des brins du ressort 62 est fixé à un téton 63 de l'une des tringles, telle que la tringle supérieure 6s. L'autre brin du ressort 62 est fixé à un autre téton 64 saillant sur le palastre de la serrure et traversant une lumière verticale 65 pratiquée dans la tringle 6s.The two other additional closing points of the lock are obtained by means of an upper vertical rod 6s and a lower vertical rod 6i. The rods 6i and 6s slide in a rectangular slide 15b made in the outer face of the body 1 against the palaster of the lock, along a vertical axis disposed at a distance from the axis Y'Y equal to the distance between l horizontal axis of rotation of the follower 4 and the axis Y'Y. The lower portion of the tail of the rod 6s and the upper portion of the tail of the rod 6i are provided with lights crossed symmetrically with respect to the X'X axis and superimposed in the slide 15b. The slots 60s and 60i receive a lug 61 passing through the transverse hole 29 of the bolt and an oblong slot 16b in the bottom of the slide 10 of the body 1. The horizontal slot 16b thus bisects the angle formed by the slots 60s and 60i of the two rods. Under these conditions, the retraction of the bolt 2 for the opening of the door produces a retreat towards the bottom of the rod 6s and a retreat towards the top of the rod 6i, and the advance of the bolt 2 for the closing of the door produces an advance towards the top of the rod 6s and an advance towards the bottom of the rod 6i. An elastic return device in the form of a vertical tension spring 62 can also be provided to return the rods 6s and 6i in the closed position, the return by the spring 62 completing the return by the spring 50 of the bolt 2. L 'one of the strands of the spring 62 is fixed to a stud 63 of one of the rods, such as the upper rod 6s. The other strand of the spring 62 is fixed to another stud 64 projecting from the palastre of the lock and passing through a vertical lumen 65 formed in the rod 6s.

Comme déjà dit, la réversibilité de la serrure est obtenue par la parfaite symétrie du corps 1 par rapport à l'axe Y'Y. Ainsi, le corps 1 possède un alésage 13b et une encoche en vé 14b à l'avant du corps 1 symétriques de l'alésage 13a et de l'encoche 14a, une glissière verticale 15a dans l'arrière de la face extérieure du corps 1 symétrique de la glissière 15b, et une lumière oblongue 16a le long de l'axe X'X symétrique de la lumière 16a. Deux plaques rectangulaires verticales symétriques 7a et 7b recouvrent deux décrochements intérieurs 17a et 17b du corps 1 de part et d'autre d'une languette verticale 12-12'. Les plaques 7a et 7b sont fixées sur les décrochements 17a et 17b par des vis 70a et 70b vissées dans des trous taraudés 19a et 19b du corps 1. Un trou 71a dans la plaque 7a est traversé par le tourillon intérieur du fouillot 4 recevant la tige carrée de la poignée de la serrure. Face à l'encoche en vé 14a, le trou 7la possède un lamage 72a pour recevoir le ressort de rappel 42 du fouillot 4.As already said, the reversibility of the lock is obtained by the perfect symmetry of the body 1 with respect to the axis Y'Y. Thus, the body 1 has a bore 13b and a vee notch 14b at the front of the body 1 symmetrical with the bore 13a and the notch 14a, a vertical slide 15a in the rear of the outer face of the body 1 symmetrical of the slide 15b, and an oblong light 16a along the axis X'X symmetrical of the light 16a. Two symmetrical vertical rectangular plates 7a and 7b cover two internal recesses 17a and 17b of the body 1 on either side of a vertical tongue 12-12 '. The plates 7a and 7b are fixed to the recesses 17a and 17b by screws 70a and 70b screwed into tapped holes 19a and 19b of the body 1. A hole 71a in the plate 7a is crossed by the inner pin of the follower 4 receiving the rod square of the lock handle. Facing the vee notch 14a, the hole 7la has a countersink 72a for receiving the return spring 42 of the follower 4.

Lorsque la serrure doit être utilisée comme une serrure en tirant à droite ou en poussant à gauche, le fouillot 4 est retourné et placé dans l'alésage 13b avec son bras 40 dans l'encoche en vé 14b. Le pêne 2 est tourné de 180° autour de l'axe Y'Y de sorte que la petite entaille 26 soit au-dessus du téton 371 du piston 37 et la grande entaille 28 soit au-dessus du bras 40 du fouillot. La tête 20 du pêne est également retournée afin que le biseau 21 soit dirigé vers l'extérieur et puisse glisser contre la gâche correspondante. Les tringles 6s et 6i sont placées dans la glissière 15a et l'ergot 61 traverse la lumière longitudinale 16a. La plaque percée 7a est placée dans le décrochement 17b et traversée par le tourillon maintenant intérieur du fouillot 4 tandis que la plaque 7b est placée dans le décrochement 17a. Le dispositif de rappel 5 est disposé symétriquement de la position illustrée par rapport à l'axe Y'Y sur le palastre, et le ressort 62 a son brin supérieur fixé à un téton analogue et symétrique au téton 64 sur le palastre.When the lock is to be used as a lock by pulling to the right or pushing to the left, the follower 4 is turned over and placed in the bore 13b with its arm 40 in the notch in vee 14b. The bolt 2 is turned 180 ° around the axis Y'Y so that the small notch 26 is above the stud 371 of the piston 37 and the large notch 28 is above the arm 40 of the follower. The head 20 of the bolt is also turned over so that the bevel 21 is directed outwards and can slide against the corresponding keeper. The rods 6s and 6i are placed in the slide 15a and the lug 61 crosses the longitudinal light 16a. The pierced plate 7a is placed in the recess 17b and crossed by the pin now inside the follower 4 while the plate 7b is placed in the recess 17a. The return device 5 is arranged symmetrically from the position illustrated with respect to the axis Y'Y on the palaster, and the spring 62 has its upper strand fixed to a pin similar and symmetrical to the pin 64 on the palaster.

On décrit maintenant le fonctionnement de la serrure selon l'invention en référence aux Figs. 2 à 5. On rappelle selon une caractéristique de l'invention, que lorsque la source d'alimentation est connectée à la bobine 31, celle-ci reçoit un courant qui produit un champ magnétique juste suffisant pour maintenir le noyau ferromagnétique 30 en position haute, et insuffissant pour attirer le noyau magnétique 30 dans la bobine lorsque le noyau est à toute autre position et notamment en position basse, comme montré à la Fig. 4. La position haute du noyau 30 est définie par la position de l'ergot 35 sur le chant longitudinal supérieur 25 du pêne, comme montré à la Fig. 2. La position basse du noyau 30 est définie par la position de l'ergot 35 dans le fond de l'encoche en vé 24 du pêne, comme montré à la Fig. 4.The operation of the lock according to the invention will now be described with reference to Figs. 2 to 5. It is recalled according to a characteristic of the invention, that when the power source is connected to the coil 31, the latter receives a current which produces a magnetic field just sufficient to maintain the ferromagnetic core 30 in the high position , and insufficient to attract the magnetic core 30 into the coil when the core is in any other position and in particular in the low position, as shown in FIG. 4. The high position of the core 30 is defined by the position of the lug 35 on the upper longitudinal edge 25 of the bolt, as shown in FIG. 2. The low position of the core 30 is defined by the position of the lug 35 in the bottom of the vee notch 24 of the bolt, as shown in FIG. 4.

En position de fermeture de la porte, la tête 20 du pêne 2 est sortie de la mortaise de la têtière du foncet de la serrure sous l'action du ressort de rappel 50. Le pêne est retenu vers l'avant par le téton 371 du piston 37 butant contre le côté arrière 261 de la petite entaille 26. La collerette 511 du guide avant 51 du ressort 50 n'est pas nécessairement en butée contre le chant arrière lla du corps 1. L'ergot transversal central 35 repose sur le chant longitudinal supérieur 25 du pêne en arrière de l'encoche en vé 24. Le noyau 30 est à fond de course en position haute dans la bobine 31, comme montré à la Fig. 2. Le bras 40 du fouillot est appliqué contre le côté avant 140a de l'encoche en vé 14a par le ressort 42. L'extrémité du bras 40 est sensiblement en arrière du côté avant 280 de la grande entaille 28.In the closed position of the door, the head 20 of the bolt 2 has come out of the mortise of the headrest of the lock bolt under the action of the return spring 50. The bolt is retained forwards by the pin 371 of the piston 37 abutting against the rear side 261 of the small notch 26. The flange 511 of the front guide 51 of the spring 50 is not necessarily in abutment against the rear edge lla of the body 1. The central transverse lug 35 rests on the upper longitudinal edge 25 of the bolt behind the vee notch 24. The core 30 is fully stroke in the high position in the coil 31, as shown in FIG. 2. The arm 40 of the follower is applied against the front side 140a of the vee notch 14a by the spring 42. The end of the arm 40 is substantially behind the front side 280 of the large notch 28.

Lorsque la tête 20 est contenue dans la gâche G de la serrure, la fermeture de la porte est maintenue par l'attraction du noyau 30 dans la bobine alimentée 31. Si l'on tente d'ouvrir la porte en tournant la poignée de la serrure suivant le sens des aiguilles d'une montre indiqué par la flèche F dans la Fig. 2, l'extrémité du bras 40 du fouillot 4 parcourt l'entaille 28 et bute contre le côté arrière 281 de l'entaille 28 pour reculer le pêne 2. Le recul du pêne 2 se produit sur une faible course jusqu'à ce que le côte avant 260 de la petite entaille rectangulaire 26 bute contre le téton 371 du piston 37. La faible course de recul du pêne ne permet pas de dégager la tête 20 à l'extérieur de la gâche G comme montré à la Fig. 3. Le champ magnétique créé par la bobine alimentée 31 maintient en position haute le noyau 30 et corollairement le boisseau 33, ce qui ne permet pas de dégager le piston 37 de l'entaille 28. La porte ne peut donc être ouverte.When the head 20 is contained in the keeper G of the lock, the closing of the door is maintained by the attraction of the core 30 in the powered coil 31. If an attempt is made to open the door by turning the handle of the lock in the clockwise direction indicated by the arrow F in Fig. 2, the end of the arm 40 of the follower 4 traverses the notch 28 and abuts against the rear side 281 of the notch 28 to retract the bolt 2. The retraction of the bolt 2 occurs on a short stroke until the front side 260 of the small rectangular notch 26 abuts the stud 371 of the piston 37. The short recoil stroke of the bolt does not allow the head 20 to be released outside the keeper G as shown in FIG. 3. The magnetic field created by the energized coil 31 maintains the core 30 and, as a corollary, the plug 33, which does not allow the piston 37 to be released from the notch 28. The door cannot therefore be opened.

L'autorisation d'ouverture de la porte est commandée par la suppression de l'alimentation de la bobine 31 de l'électro-aimant 3. Le début du recul du pêne demi-tour 2 s'effectue comme précédemment par rotation du bras 40 du fouillot 4 vers l'arrière. Cependant, la bobine n'étant pas alimentée, le noyau 30 et le boisseau 33 solidaires descendent par gravité lorsque le pêne 2 recule, de sorte que l'ergot 35 glisse sur le côté arrière 241 de l'encoche 24 jusqu'au fond de celle-ci. A cet instant, le téton 371 du piston 37 est dégagé de l'entaille inférieure rectangulaire 26 du pêne, comme montré à la Fig. 4. Ceci permet de poursuivre le recul du pêne par rotation du bras 40 du fouillot 4 toujours suivant la flèche F, jusqu'à mise en butée du bras 40 contre le côté arrière 141a de l'encoche 14a. Le pêne 2 est alors à la position d'ouverture pour laquelle la tête 20 du pêne est complètement dégagée de la gâche G, comme montré à. la Fig. 5. Au cours du recul du pêne 2 à partir du dégagement du piston 37 de l'entaille 26, le noyau 30 et le boisseau 33 remonte suite au glissement de l'ergot 35 sur le côté avant 240 de l'encoche en vé 24, puis sur le chant supérieur 25 du pêne 2. Simultanément, le chant inférieur 27 du pêne glisse contre le téton 371 du piston 37 et le ressort 36 est comprimé dans la chambre 334 par la remontée du boisseau 33. Simultanément au recul du pêne demi-tour 2, la tringle supérieure 6s descend et la tringle inférieure 6i monte grâce au recul de l'ergot 61 glissant horizontalement dans les lumières croisées 60s et 60i et dans la lumière longitudinale 16b. Dans ces conditions, la serrure à trois points est en position d'ouverture.The authorization to open the door is controlled by removing the power from the coil 31 of the electromagnet 3. The start of the reversal of the latch bolt 2 is carried out as previously by rotation of the arm 40 of follower 4 to the rear. However, the reel not being supplied, the core 30 and the plug 33 integral descend by gravity when the bolt 2 moves back, so that the lug 35 slides on the rear side 241 of the notch 24 to the bottom of this one. At this instant, the stud 371 of the piston 37 is released from the rectangular lower notch 26 of the bolt, as shown in FIG. 4. This makes it possible to continue the retraction of the bolt by rotation of the arm 40 of the follower 4 always following the arrow F, until the arm 40 abuts against the rear side 141a of the notch 14a. The bolt 2 is then at open position for which the head 20 of the bolt is completely disengaged from the keeper G, as shown in. Fig. 5. During the retraction of the bolt 2 from the release of the piston 37 from the notch 26, the core 30 and the plug 33 rises following the sliding of the lug 35 on the front side 240 of the vee notch 24 , then on the upper edge 25 of the bolt 2. Simultaneously, the lower edge 27 of the bolt slides against the stud 371 of the piston 37 and the spring 36 is compressed in the chamber 334 by the raising of the plug 33. Simultaneously with the retraction of the half bolt -tower 2, the upper rod 6s goes down and the lower rod 6i goes up thanks to the recoil of the lug 61 sliding horizontally in the crossed lights 60s and 60i and in the longitudinal light 16b. Under these conditions, the three-point lock is in the open position.

Le relâchement de la poignée de la serrure à partir de la position d'ouverture montrée à la Fig. 5 replace les différents éléments mobiles de la serrure aux positions respectives de fermeture montrée à la Fig. 2. Le retour aux positions de fermeture est dû aux poussées exercées par les ressorts 50 et 36. Le ressort 50 pousse la queue du pêne 2 vers l'avant. Le côté avant 281 de l'encoche 28 pousse le bras 40 du fouillot, que le ressort 42 soit présent ou absent. La présence du ressort 42 n'est justifiée que dans la seconde variante décrite plus loin. Dès que le côté avant 260 de l'entaille inférieure 26 a franchi le téton 371 du piston 37, le téton 371 est engagé dans l'entaille 26 par le ressort 36. Après glissement de l'ergot 35 sur les côtés 240 et 241 de l'encoche en vé 24, le boisseau 33 et le noyau 30 sont en position haute. L'avance du pêne 2 entraîne par l'intermédiaire de l'ergot 61 la montée de la tringle supérieure 6s et la descente de la tringle inférieure 6i. Le déplacement des tringles est accentué par la traction du ressort 62 bien que celui-ci ne soit pas indispensable.Releasing the lock handle from the open position shown in Fig. 5 replaces the various movable elements of the lock in the respective closed positions shown in FIG. 2. The return to the closed positions is due to the thrusts exerted by the springs 50 and 36. The spring 50 pushes the tail of the bolt 2 forward. The front side 281 of the notch 28 pushes the arm 40 of the follower, whether the spring 42 is present or absent. The presence of the spring 42 is only justified in the second variant described below. As soon as the front side 260 of the lower notch 26 has crossed the stud 371 of the piston 37, the stud 371 is engaged in the notch 26 by the spring 36. After sliding of the lug 35 on the sides 240 and 241 of the vee notch 24, the plug 33 and the core 30 are in the high position. The advance of the bolt 2 drives via the lug 61 the rise of the upper rod 6s and the descent of the lower rod 6i. The displacement of the rods is accentuated by the pulling of the spring 62 although this is not essential.

Si la bobine 31 de l'électro-aimant 3 est alimentée avant que la poignée de la serrure soit relâchée, tout se passe comme précédemment à l'exception que le noyau 30 est maintenu en position haute dans la bobine 31 et que l'encoche en vé 24 du pêne passe en-dessous de l'ergot 35 sans recevoir celui-ci. Par contre, si la bobine 31 est alimentée lorsque la poignée est relâchée après ouverture de la porte, le pêne 2 est ramené à la position montrée à la Fig. 2. Dans ce cas, la porte ne peut être fermée puisque le noyau 30 et boisseau 33 sont maintenus en position haute et par suite le téton 371 du piston 37 ne peut être dégagé de l'encoche 26 pour le recul du pêne.If the coil 31 of the electromagnet 3 is energized before the handle of the lock is released, everything goes as above except that the core 30 is held in the high position in the coil 31 and the notch in vé 24 of the bolt pass below lug 35 without receiving it. On the other hand, if the coil 31 is supplied when the handle is released after opening the door, the bolt 2 is returned to the position shown in FIG. 2. In this case, the door cannot be closed since the core 30 and plug 33 are kept in the high position and consequently the stud 371 of the piston 37 cannot be released from the notch 26 for the retraction of the bolt.

La seconde réalisation montrée aux Figs. 6 à 9 remédie à cet inconvénient et notamment permet une condamnation de la serrure en position de fermeture sans que la bobine soit nécessairement alimentée. La serrure selon la seconde réalisation comprend les éléments de la première réalisation avec l'adjonction nécessaire du ressort de rappel 42 du fouillot 4 ainsi qu'un interrupteur ou contacteur miniature 8 et un levier 43 commandant le contacteur 8.The second embodiment shown in Figs. 6 to 9 overcomes this drawback and in particular allows the lock to be locked in the closed position without the coil being necessarily supplied. The lock according to the second embodiment comprises the elements of the first embodiment with the necessary addition of the return spring 42 of the follower 4 as well as a miniature switch or contactor 8 and a lever 43 controlling the contactor 8.

Le boîtier du contacteur 8 est fixé sur la plaque 7a traversée par le fouillot 4. Le contacteur 8 est connecté en série entre l'une des bornes 32 de la bobine 31, et l'une des bornes de la source d'alimentation de la bobine. Le contact mobile 80 du contacteur 8 est solidaire d'un petit coulisseau 81 coulissant parallèlement à l'axe X'X, traversant complètement le boîtier du contacteur. Un petit ressort 82 contenu dans le boîtier du contacteur 8 rappelle vers l'arrière le contact mobile 80 en position fermée pour laquelle l'extrémité arrière du coulisseau 81 saille sur le côté arrière du boîtier. Le levier 43 est fixé par deux vis à la périphérie du tourillon intérieur du fouillot 4, au-dessus de la plaque 7a. Lorsque le bras 40 du fouillot est appliqué contre le côté avant 140a de l'encoche 14a par la traction du ressort 42, le levier 43 est sensiblement vertical et est plaqué contre le coté arrière du boîtier du contacteur 8, ce qui pousse vers l'avant le contact mobile 80 et ouvre le contacteur 8, comme montré à la Fig. 6. Le contacteur 8 est fermé lorsque le fouillot a tourné d'un faible angle de manière à dégager l'extrémité du levier derrière le coulisseau 81, ce qui permet au ressort 82 d'appliquer le contact mobile 80 sur le contact stationnaire 83 du contacteur comme montré aux Figs. 8 et 9.The housing of the contactor 8 is fixed to the plate 7a traversed by the follower 4. The contactor 8 is connected in series between one of the terminals 32 of the coil 31, and one of the terminals of the power source of the coil. The movable contact 80 of the contactor 8 is integral with a small slide 81 sliding parallel to the axis X'X, completely passing through the housing of the contactor. A small spring 82 contained in the housing of the contactor 8 recalls rearward the movable contact 80 in the closed position for which the rear end of the slide 81 projects on the rear side of the housing. The lever 43 is fixed by two screws to the periphery of the inner pin of the follower 4, above the plate 7a. When the arm 40 of the follower is applied against the front side 140a of the notch 14a by the traction of the spring 42, the lever 43 is substantially vertical and is pressed against the rear side of the housing of the contactor 8, which pushes towards the before the movable contact 80 and opens the contactor 8, as shown in FIG. 6. The contactor 8 is closed when the follower has turned a small angle so as to release the end of the lever behind the slide 81, which allows the spring 82 to apply the movable contact 80 to the stationary contact 83 of the contactor as shown in Figs. 8 and 9.

En position de fermeture, avec alimentation non coupée à distance, comme montré à la Fig. 6 d'une manière analogue à la Fig. 2, le contacteur 8 est ouvert et la bobine 31 n'est pas alimentée ; et ne consomme donc pas de courant. Une faible rotation de la poignée et donc du fouillot 4 correspondant à une faible rotation du bras 40 du fouillot dans l'entaille arrière 28 du pêne demi-tour 2 provoque le recul du levier 43 et la fermeture du contacteur 8 et par suite l'alimentation de la bobine 31 et le maintien en position haute du noyau 30 et du boisseau 33 et donc du piston 37 avant que le bras 40 atteigne le côté arrière 281 de l'encoche 28 et le pêne 2 recule, c'est-à-dire avant que l'ergot 35 atteigne le côté arrière 241 de l'encoche 24. Une tentative d'ouverture non autorisée est ainsi empêchée grâce à la retenue du pêne par le piston 37 dans l'entaille 26, d'une manière analogue à la Fig. 3. Cependant, selon la seconde réalisation, l'entaille 28 est plus longue.In the closed position, with the supply unconnected from a distance, as shown in Fig. 6 in a manner analogous to FIG. 2, the contactor 8 is open and the coil 31 is not supplied; and therefore does not consume current. A slight rotation of the handle and therefore of the follower 4 corresponding to a slight rotation of the arm 40 of the follower in the rear notch 28 of the latch bolt 2 causes the lever 43 to recede and the contactor 8 to close and consequently the supply of the coil 31 and the holding in the high position of the core 30 and of the plug 33 and therefore of the piston 37 before the arm 40 reaches the rear side 281 of the notch 28 and the bolt 2 moves back, that is to say say before the lug 35 reaches the rear side 241 of the notch 24. An unauthorized opening attempt is thus prevented by the retention of the bolt by the piston 37 in the notch 26, in a manner similar to Fig. 3. However, according to the second embodiment, the notch 28 is longer.

L'ouverture autorisée de la porte s'effectue d'une manière analogue aux Figs. 4 et 5 en déconnectant la source d'alimentation.The authorized opening of the door is carried out in a manner analogous to FIGS. 4 and 5 by disconnecting the power source.

Par contre, selon la seconde réalisation, une fois que la porte est ouverte, et que la poignée est relâchée, comme montré à la Fig. 6, la porte peut être refermée, que l'alimentation à distance de la bobine soit coupée ou non. Une telle fermeture peut être effectuée en poussant brusquement le battant de la porte. La tête 20 du pêne demi-tour vient. au contact de la gâche G de la serrure, ce qui pousse vers l'arrière le pêne 2. Lorsque le côté avant 260 de la petite entaille inférieure 26 bute contre le téton 371 du piston 37, le côté avant 280 de la grande entaille inférieure 28 a déjà poussé le bras 40 du fouillot suivant une rotation suffisante pour dégager le levier 43 du côté arrière du boîtier du contacteur 8, comme montré à la Fig. 7. Ce dégagement permet au ressort 82 de plaquer le contact mobile 80 contre le contact stationnaire 83 et donc de fermer le contacteur 8. Au cours de ce faible recul du pêne 2, la bobine n'étant pas alimentée grâce à l'ouverture du contacteur 8, le noyau 30 descend par gravité et par suite l'ergot 35 glisse sur une faible portion du coté arrière 241 de l'encoche en vé 24 du pêne. Ainsi, à la position montrée à la Fig. 7, le noyau 30 est déjà descendu lorsque le contacteur 8 est fermé ; la bobine alimentée ou non ne peut pas attirer en position haute le noyau qui cGntinue ainsi sa descente par gravité afin que le téton 371 du piston 37 soit dégagé de l'entaille 26 et que le pêne poursuive sa course de recul.On the other hand, according to the second embodiment, once the door is open, and the handle is released, as shown in FIG. 6, the door can be closed, whether the remote power supply to the coil is cut or not. Such a closure can be effected by abruptly pushing the door leaf. The head 20 of the U-bolt comes. in contact with the keeper G of the lock, which pushes back the bolt 2. When the front side 260 of the small lower notch 26 abuts against the stud 371 of the piston 37, the front side 280 of the large lower notch 28 has already pushed the arm 40 of the follower in sufficient rotation to release the lever 43 from the rear side of the housing of the contactor 8, as shown in FIG. 7. This clearance allows the spring 82 to press the movable contact 80 against the stationary contact 83 and therefore to close the contactor 8. During this slight retraction of the bolt 2, the reel not being supplied thanks to the opening of the contactor 8, the core 30 descends by gravity and consequently the lug 35 slides on a small portion of the rear side 241 of the vee notch 24 of the bolt. So at the position shown at Fig. 7, the core 30 is already lowered when the contactor 8 is closed; the reel supplied or not can not attract in the high position the core which cGntinue thus its descent by gravity so that the stud 371 of the piston 37 is released from the notch 26 and that the bolt continues its recoil stroke.

Lors de la poursuite du recul du pêne 2, l'ergot 35 atteint le fond de l'encoche 24 et le téton 371 du piston 37 est franchi par l'entaille 26, comme montré à la Fig. 8. Le bras 40 du fouillot 4 est toujours poussé vers l'arrière par le côté avant 280 de la grande entaille inférieure 28. Le levier 43 est complètement désengagé du petit coulisseau 81 du contacteur fermé 8. Le recul du pêne se poursuit jusqu'à ce que l'extrémité de la tête 20 du pêne glisse contre la gâche G de la serrure comme montré à la Fig. 9 d'une manière analogue à la Fig. 5. L'ergot 35 est de nouveau sur le chant supérieur 25 du pêne.During the continuation of the retraction of the bolt 2, the lug 35 reaches the bottom of the notch 24 and the stud 371 of the piston 37 is crossed by the notch 26, as shown in FIG. 8. The arm 40 of the follower 4 is always pushed backwards by the front side 280 of the large lower notch 28. The lever 43 is completely disengaged from the small slide 81 of the closed contactor 8. The retraction of the bolt continues until that the end of the bolt head 20 slides against the keeper G of the lock as shown in FIG. 9 in a manner analogous to FIG. 5. The lug 35 is again on the upper edge 25 of the bolt.

La fermeture de la porte par pénétration de la tête 20 dans la gâche G s'effectue comme selon la première réalisation grâce à la poussée du pêne 2 excercée vers l'avant par le ressort 50 et grâce à la poussée du piston 37 dans l'entaille 26 exercée vers le haut par le ressort 36. Le bras 40 du fouillot 4 est appliqué contre le côté avant 280 de l'entaille 28 par la traction exercée par le brin 420 du ressort 42 lors de l'avance du pêne. Avant que le bras 40 du fouillot soit appliqué contre le côté avant 140a de l'encoche 14a dans le corps 1 par le ressort 42, le levier 43 pousse le petit coulisseau 81, ce qui dégage le contact mobile 80 du contact stationnaire 83 et ouvre le contacteur 8. La source d'alimentation de la bobine 31 présente ou non est de toute façon sans effet grâce à l'ouverture du contacteur 8 pour la position de fermeture de la porte.The closing of the door by penetration of the head 20 into the keeper G is carried out as according to the first embodiment thanks to the push of the bolt 2 exerted forwards by the spring 50 and thanks to the push of the piston 37 in the notch 26 exerted upwards by the spring 36. The arm 40 of the follower 4 is applied against the front side 280 of the notch 28 by the traction exerted by the strand 420 of the spring 42 when the bolt advances. Before the arm 40 of the follower is applied against the front side 140a of the notch 14a in the body 1 by the spring 42, the lever 43 pushes the small slide 81, which releases the movable contact 80 from the stationary contact 83 and opens the contactor 8. The power source of the coil 31 present or not is in any case without effect thanks to the opening of the contactor 8 for the closed position of the door.
