- This device essentially comprises a bolt 1 slidably mounted in a body 2 and which can cooperate with a notch 3 forming a keeper formed in any member, such as for example a bar 4 carrying bolts 5 allowing, by actuation of the bar 4, the locking or unlocking a safe door for example.
- the body 2 has at one of its ends an opening 6 allowing the passage of the bolt 1, and is closed at the other of its ends by a removable bottom 7.
- the bolt 1 consists of a rear piece 8 in the form of a socket and of a front piece 9 capable of cooperating with the keeper 3 and mounted relatively mobile relative to the rear piece 8.
- the rear piece 8 and the front piece 9 bolt 1 are slidably mounted in the body 2.
- the front part 9 of the bolt 1 is constituted by a hollow element 10 in which slides a rod 11 provided at its free end with a stop 12 capable of sliding in the bore 10a of the hollow element 10.
- a first spring R1 surrounding the rod 11 and housed inside the bore 10a abuts on the one hand on the stop 12 and on the other hand on the rear part 10b of the element 10 and through which the rod 11 passes.
- the spring R1 constantly biases the hollow element 10 bearing on the stop 12 of the rod 11.

- a second spring R2 surrounds the rod 11 and bears on the one hand on the rear part or heel 8a of the part 8 and on the other hand on the bottom 7 of the body 2.
- the rear part 8 of the bolt 1 has in a way the shape of a socket and has two external and spaced annular grooves 15 and 16. These two grooves 15 and 16 can cooperate with the core 17 of a second electromagnet 18 fixed on the side of the body 2 by means of a tab 19 for example.
- a third spring R3 mounted around the core 17 bears on the one hand on the body of the electromagnet 18 and on the other hand on a ring or the like 20 integral with the core 17 and sliding in a bore 21 formed through the wall of the body 2 and opening onto the rear part 8 of the bolt 1.
- the bore 21 and therefore the core 17 of the electromagnet 18 extend in a direction orthogonal to the axis X-X ⁇ of the body 2, this axis also being that of the bolt 1 constituted by the rear part 8 and the front part 9 which cooperates with the keeper 3.

- the body 1 of course includes an axial cavity 22 in which the bolt slides 1. There is shown at 23 a shoulder formed in the cavity 22 and which limits the stroke of the rear part 8 of the bolt 1 forwards under the effect compression of the second spring R2. Indeed, as can be seen in Figure 1, the heel 8a of the part 8 abuts on the shoulder 23 in question, which corresponds to a position introduced by the front part 9 of the bolt 1 in the notch 3 from bar 4.
- the bar 4 is blocked by the front part or part 9 of the bolt 1.
- the exit of the front part 9 of the keeper 3 is prohibited by the presence of the rear part 8 whose groove 16 receives the core 17 of the electromagnet 18. In this position, the system is at rest and the electromagnets 13 and 18 are not energized.
- the electromagnet 13 While maintaining the excitation of the electromagnet 18, the electromagnet 13 is excited, which, as seen in FIG. 3, causes the rod 11 constituting the core of the electro-recoil magnet 13. Consequently, the crew constituted by the rear part 8 and the front part 9 both constituting the bolt 1 is moved until the heel 8a of the part 8 comes to abut against the bottom 7 of the body 2 In this position, visible in FIG. 3, the front part 9 of the bolt 1 has come out of the keeper 3, and the spring R2 is compressed.
- the electromagnets 13 and 18 are excited simultaneously, which allows the core 17 of the electromagnet 18 to come out of the groove 15 of the rear part 8, as is seen in Figure 5. It should be noted here that the spring R2 is compressed, as well as the spring R3.
- FIGS. 8 and 9 We will now refer to FIGS. 8 and 9 to briefly explain the operation of the device in the event of the front part 9 of the bolt 1 jamming in the notch 3 of the bar 4.
- FIG. 8 This state is illustrated in FIG. 8 where we see the wall of the notch 3 of the bar 4 resting on the front part 9 of the bolt 1.
- the locking cycle can be carried out as explained with reference to FIGS. 5 to 7, but here, as can be seen in FIG. 11, the element 10 of the bolt is not engaged in the notch 3 of the bar 4 and abuts on this bar while being compressed by the spring R2.
- the core 17 of the electromagnet 18 is supported on the rear part 8 of the bolt 1 between the two grooves 15 and 16.
- the bar 4 is in the correct position, that is to say that the notch 3 will be in front of the element 10
- this element will enter the notch under the effect of the compression of the spring R2, and the locking of the bolt 1 will be obtained by the penetration of the core 17 of the electro- like 18 in the groove 16 of the rear part 8 of the bolt 1.
- a locking and unlocking device has therefore been produced according to the invention which consumes a minimum of electric current, which makes it possible to obtain a locking of the bolt in the locked and unlocked position, and which overcomes the drawbacks of jamming and failure to alignment of the bolt with respect to the member to be locked.

Description
La présente invention a pour objet un dispositif de verrouillage et déverrouillage d'un organe quelconque, tel que par exemple une barre portant des pênes susceptibles de coopérer avec des gâches pour verrouiller une porte, par exemple.The present invention relates to a device for locking and unlocking any organ, such as for example a bar carrying bolts capable of cooperating with strikes to lock a door, for example.
On connait déjà des systèmes actionnés par le courant électrique pour commander les verrous de serrure.We already know systems actuated by electric current to control locks.
C'est ainsi que l'on a déjà proposé d'équiper les portes d'une gâche électrique coopérant avec un pêne classique ou demi-tour. Plus précisément, la gâche est équipée d'un petit volet mobile qui s'escamote sous l'effet du courant et libère par conséquent le pêne.Thus it has already been proposed to equip the doors with an electric strike cooperating with a conventional bolt or U-turn. More specifically, the keeper is equipped with a small movable flap which retracts under the effect of the current and consequently releases the bolt.
Ce système présente des inconvénients. Tout d'abord, il consomme une certaine quantité d'énergie électrique dans la mesure où le volet de la gâche doit être maintenu excité électriquement un certain temps nécessaire au déverrouillage. En outre, le verrouillage du pêne demi-tour dans la gâche n'est pas positif, puisque ce pêne demi-tour est sollicité par un simple ressort et peut être facilement crocheté et extrait de la gâche électrique.This system has drawbacks. First of all, it consumes a certain amount of electrical energy insofar as the strike flap must be kept electrically excited for a certain time necessary for unlocking. In addition, the locking of the U-bolt in the strike is not positive, since this U-bolt is biased by a simple spring and can be easily hooked and extracted from the electric strike.
Il existe également des systèmes de verrouillage et de déverrouillage comprenant un pêne classique monté coulissant dans un corps et actionné par un électro-aimant permettant à ce pêne de pénétrer dans une gâche et d'en sortir. Mais ce système présente aussi le même genre d'inconvénients.There are also locking and unlocking systems comprising a conventional bolt mounted to slide in a body and actuated by an electromagnet allowing this bolt to enter and leave a strike. But this system also has the same kind of drawbacks.
En effet, le pêne, qui peut être constitué par le noyau de l'électro-aimant, conduit généralement à une structure d'électro-aimant qui est surdimensionnée et qui doit être sollicitée longtemps par le courant pour permettre la sortie du pêne de la gâche, ce qui nécessite une consommation d'énergie électrique relativement importante. En outre, comme pour les gâches électriques, il n'y a pas de blocage positif du pêne en position verrouillée, de sorte qu'à l'aide d'un outil on peut facilement manoeuvrer ce pêne, formant noyau de l'électro-aimant, pour le sortir de sa gâche. Enfin, en cas d'incident résultant par exemple du coincement du pêne dans la gâche, ce qui empêche son retrait, ou encore du défaut d'alignement du pêne avec la gâche, ce qui empêche son introduction dans ladite gâche, on comprend que l'électro-aimant sera maintenu excité par l'utilisateur pendant un temps très long pour tenter d'exécuter malgré tout l'opération de verrouillage ou de déverrouillage, ce qui peut conduire à l'endommagement ou même à la mise hors service de l'électro-aimant.Indeed, the bolt, which can be constituted by the core of the electromagnet, generally leads to an electromagnet structure which is oversized and which must be stressed for a long time by the current to allow the bolt to exit the keeper, which requires a relatively high consumption of electrical energy. In addition, as with electric strikes, there is no positive blocking of the bolt in the locked position, so that with the help of a tool, this bolt can easily be operated, forming the core of the electro- loving, to get it out of its waste. Finally, in the event of an incident resulting for example from the jamming of the bolt in the strike, which prevents its removal, or else from the lack of alignment of the bolt with the strike, which prevents its introduction into said strike, it is understood that the the electromagnet will be kept energized by the user for a very long time in an attempt to execute, despite everything, the locking or unlocking operation, which can lead to damage or even to deactivation of the electro magnet.
La présente invention a pour but de remédier notamment aux inconvénients ci-dessus en proposant un dispositif qui n'exige qu'une très faible consommation de courant électrique et qui, au surplus, assure un blocage positif du pêne qu'il soit en position de verrouillage ou de déverrouillage.The object of the present invention is to remedy the above drawbacks in particular by proposing a device which requires only a very low consumption of electric current and which, moreover, ensures a positive blocking of the bolt that it is in the position of locking or unlocking.
A cet effet, l'invention a pour objet un dispositif de verrouillage et déverrouillage d'un organe quelconque, et du type comprenant au moins un pêne monté coulissant dans un corps et actionné par un électro-aimant permettant à ce pêne de coopérer ou non avec une encoche ou analogue formant gâche ménagée dans ledit organe, caractérisé en ce qu'il comprend un deuxième électro-aimant coopérant avec l'autre ou premier électro-aimant pour agir positivement sur le pêne afin notamment de le bloquer dans le corps lorsqu'il se trouve dans une position correspondant à sa position d'introduction dans la gâche ou dans une position correspondant à sa position de sortie de ladite gâche.To this end, the subject of the invention is a device for locking and unlocking any organ, and of the type comprising at least one bolt mounted to slide in a body and actuated by an electromagnet allowing this bolt to cooperate or not with a notch or the like forming a keeper formed in said member, characterized in that it comprises a second electromagnet cooperating with the other or first electromagnet to act positively on the bolt in particular to block it in the body when it is in a position corresponding to its position of introduction into the keeper or in a position corresponding to its position of exit from said keeper.
Suivant une autre caractéristique de l'invention, le pêne est formé d'une part d'une pièce arrière coopérant avec le noyau du deuxième électro-aimant, et d'autre part d'une pièce avant susceptible de coopérer avec la gâche et montée relativement mobile par rapport à la pièce arrière.According to another characteristic of the invention, the bolt is formed on the one hand by a rear part cooperating with the core of the second electromagnet, and on the other hand by a front part capable of cooperating with the keeper and mounted relatively mobile compared to the rear part.
On précisera ici que la pièce arrière du pêne comporte sur sa périphérie deux évidements ou rainures annulaires espacées coopérant avec le noyau du deuxième électro-aimant.It will be specified here that the rear part of the bolt has on its periphery two recesses or spaced annular grooves cooperating with the core of the second electromagnet.
Selon encore une autre caractéristique de cette invention, la pièce avant du pêne est constituée par un élément creux dans lequel coulisse une tige portant à son extrémité libre une butée pour un premier ressort entourant la tige et sollicitant constamment l'élément creux en position d'appui contre la butée, cette tige étant solidaire de la pièce arrière du pêne qu'elle traverse et constituant le noyau du premier électro-aimant.According to yet another characteristic of this invention, the front piece of the bolt is constituted by a hollow element in which slides a rod carrying at its free end a stop for a first spring surrounding the rod and constantly urging the hollow element in position bearing against the stop, this rod being integral with the rear part of the bolt which it crosses and constituting the core of the first electromagnet.
Suivant encore une autre caractéristique du dispositif selon cette invention, un deuxième ressort entoure la tige précitée et prend appui entre la pièce arrière du pêne et le fond du corps dans lequel coulisse le pêne.According to yet another characteristic of the device according to this invention, a second spring surrounds the above-mentioned rod and bears between the rear part of the bolt and the bottom of the body in which the bolt slides.
Un troisième ressort est également prévu pour solliciter constamment le noyau du deuxième électro-aimant en direction de la pièce arrière du pêne.A third spring is also provided for constantly biasing the core of the second electromagnet in the direction of the rear part of the bolt.
Selon encore une autre caractéristique de cette invention, le premier électro-aimant est fixé extérieurement sur le corps et dans l'axe de ce corps, tandis que le deuxième électro-aimant est fixé extérieurement sur le corps de telle manière que son noyau soit orthogonal à l'axe du corps et traverse un alésage ménagé dans ledit corps et débouchant sur la pièce arrière du pêne.According to yet another characteristic of this invention, the first electromagnet is fixed externally to the body and in the axis of this body, while the second electromagnet is fixed externally to the body so that its core is orthogonal to the axis of the body and passes through a bore formed in said body and opening onto the rear part of the bolt.
On précisera encore ici que les deux électro-aimants sont électriquement reliés de manière à permettre leur excitation ou désexcitation sélective en fonction de la séquence d'opérations à effectuer pout notamment libérer, actionner et bloquer le pêne dans le corps.It will also be specified here that the two electromagnets are electrically connected so as to allow their selective excitation or de-excitation according to the sequence of operations to be carried out in particular releasing, actuating and blocking the bolt in the body.
Mais d'autres caractéristiques et avantages de l'invention apparaîtront mieux dans la description détaillée qui suit et se réfère aux dessins annexés donnés uniquement à titre d'exemple.However, other characteristics and advantages of the invention will appear better in the detailed description which follows and refers to the appended drawings given solely by way of example.
Toutes les figures 1 à 11 sont des vues en coupe axiale du dispositif conforme à cette invention et illustrent diverses étapes du fonctionnement de ce dispositif.All Figures 1 to 11 are views in axial section of the device according to this invention and illustrate various stages of operation of this device.
Plus précisément, les figures 1 à 4 illustrent les étapes successives permettant le passage du dispositif de la position verrouillée à la position déverrouillée, tandis que les figures 5 à 7 illustrent le passage de la position déverrouillée à la position verrouillée.More specifically, FIGS. 1 to 4 illustrate the successive steps allowing the device to pass from the locked position to the unlocked position, while FIGS. 5 to 7 illustrate the passage from the unlocked position to the locked position.
Les figures 8 et 9 illustrent le fonctionnement du dispositif en cas de coincement du pêne dans la gâche, et les figures 10 et 11 illustrent le fonctionnement du dispositif en cas de défaut d'alignement du pêne avec la gâche.Figures 8 and 9 illustrate the operation of the device in case of jamming of the bolt in the keeper, and Figures 10 and 11 illustrate the operation of the device in case of misalignment of the bolt with the keeper.
Sur toute ces figures, on retrouve, dans des positions différentes, les mêmes éléments qui sont désignés par des repères communs. Dès lors, on se reportera seulement à la figure 1 pour décrire la structure du dispositif conforme à la présente invention et montré en vue agrandie.On all these figures, we find, in different positions, the same elements which are designated by common references. Consequently, reference will only be made to FIG. 1 to describe the structure of the device according to the present invention and shown in an enlarged view.
Ce dispositif comprend essentiellement un pêne 1 monté coulissant dans un corps 2 et pouvant coopérer avec une encoche 3 formant gâche ménagée dans un organe quelconque, tel que par exemple une barre 4 portant des pênes 5 permettant, par actionnement de la barre 4, le verrouillage ou le déverrouillage d'une porte de coffre-fort par exemple.This device essentially comprises a bolt 1 slidably mounted in a
Le corps 2 possède à l'une de ses extrémités une ouverture 6 permettant le passage du pêne 1, et est fermée à l'autre de ses extrémités par un fond démontable 7.The
Le pêne 1 est constitué d'une pièce arrière 8 en forme de douille et d'une pièce avant 9 susceptible de coopérer avec la gâche 3 et montée relativement mobile par rapport à la pièce arrière 8. La pièce arrière 8 et la pièce avant 9 du pêne 1 sont montées à coulissement dans le corps 2.The bolt 1 consists of a
Plus précisément, la pièce avant 9 du pêne 1 est constituée par un élément creux 10 dans lequel coulisse une tige 11 munie à son extrémité libre d'une butée 12 pouvant coulisser dans l'alésage 10a de l'élément creux 10. Un premier ressort R₁ entourant la tige 11 et logé à l'intérieur de l'alésage 10a bute d'une part sur la butée 12 et d'autre part sur la partie arrière 10b de l'élément 10 et au travers de laquelle passe la tige 11. Ainsi, comme on le comprend, le ressort R₁ sollicite constamment l'élément creux 10 en appui sur la butée 12 de la tige 11. On ajoutera ici que la partie arrière 10b de l'élément creux 10 prend normalement appui sur la pièce arrière 8 du pêne 1.More specifically, the front part 9 of the bolt 1 is constituted by a
La tige 11 est fixée sur cette pièce arrière 8 qu'elle traverse et constitue le noyau d'un premier électro-aimant 13 extérieurement fixé sur le corps 2 par l'intermédiaire d'une patte ou analogue 14 et ce suivant l'axe X-Xʹ de ce corps.The
Un deuxième ressort R₂ entoure la tige 11 et prend appui d'une part sur la partie arrière ou talon 8a de la pièce 8 et d'autre part sur le fond 7 du corps 2.A second spring R₂ surrounds the
La pièce arrière 8 du pêne 1 présente en quelque sorte la forme d'une douille et comporte deux rainures annulaires externes et espacées 15 et 16. Ces deux rainures 15 et 16 peuvent coopérer avec le noyau 17 d'un deuxième électro-aimant 18 fixé sur le côté du corps 2 par l'intermédiaire d'une patte 19 par exemple.The
Un troisième ressort R₃ monté autour du noyau 17 prend appui d'une part sur le corps de l'électro-aimant 18 et d'autre part sur une bague ou analogue 20 solidaire du noyau 17 et coulissant dans un alésage 21 ménagé au travers de la paroi du corps 2 et débouchant sur la pièce arrière 8 du pêne 1. L'alésage 21 et donc le noyau 17 de l'electro-aimant 18 s'étendent suivant une direction orthogonale à l'axe X-Xʹ du corps 2, cet axe étant aussi celui du pêne 1 constitué par la pièce arrière 8 et la pièce avant 9 qui coopère avec la gâche 3.A third spring R₃ mounted around the
Bien entendu, les rainures 15 et 16 de la pièce arrière 8 pourraient être constituées par des évidements de forme quelconque susceptibles de coopérer avec le noyau 17 du deuxième électro-aimant 18, et cela sans sortir du cadre de l'invention.Of course, the
Le corps 1 comporte bien sûr une cavité axiale 22 dans laquelle coulisse le pêne 1. On a montré en 23 un épaulement formé dans la cavité 22 et qui limite la course de la pièce arrière 8 du pêne 1 vers l'avant sous l'effet de la compression du deuxième ressort R₂. En effet, comme on le voit bien sur la figure 1, le talon 8a de la pièce 8 vient buter sur l'épaulement 23 en question, ce qui correspond à une position introduite de la pièce avant 9 du pêne 1 dans l'encoche 3 de la barre 4.The body 1 of course includes an
Ayant ainsi décrit la structure du dispositif selon l'invention, on en expliquera maintenant le fonctionnement.Having thus described the structure of the device according to the invention, we will now explain its operation.
Tout d'abord, on partira de la position de verrouillage représentée sur la figure 1 pour expliquer comment s'effectue le déverrouillage en s'aidant des figures 2 à 4.First of all, we will start from the locking position shown in Figure 1 to explain how unlocking is carried out with the help of Figures 2 to 4.
Comme on le voit sur la figure 1, la barre 4 est bloquée par la partie ou pièce avant 9 du pêne 1. La sortie de la pièce avant 9 de la gâche 3 est interdite par la présence de la pièce arrière 8 dont la rainure 16 reçoit le noyau 17 de l'électro-aimant 18. Dans cette position, le système est au repos et les électro-aimants 13 et 18 ne sont pas excités.As seen in Figure 1, the bar 4 is blocked by the front part or part 9 of the bolt 1. The exit of the front part 9 of the
Par excitation de l'électro-aimant 18, et comme on le voit bien sur la figure 2, le noyau 17 est soulevé à l'encontre de la force du ressort R₃ qui est comprimé. La pièce arrière ou douille 8 du pêne 1 est donc libre.By excitation of the
Tout en maintenant l'excitation de l'électro-aimant 18, on excite l'électro-aimant 13, ce qui, comme on le voit sur la figure 3, provoque le recul de la tige 11 constituant le noyau de l'électro-aimant 13. Dès lors, l'équipage constitué par la pièce arrière 8 et la pièce avant 9 constituant toutes les deux le pêne 1 est déplacé jusqu'à ce que le talon 8a de la pièce 8 vienne buter contre le fond 7 du corps 2. Dans cette position, visible sur la figure 3, la partie avant 9 du pêne 1 est sortie de la gâche 3, et le ressort R₂ est comprimé.While maintaining the excitation of the
L'excitation de l'électro-aimant 13 est maintenue et l'excitation de l'électro-aimant 18 est coupée. Dès lors, le ressort R₃ de rappel du noyau 17 de l'électro-aimant 18 provoque la descente de ce noyau dans la rainure 15 de la pièce arrière 8 du pêne 1. La barre 4 est donc déverrouillée et le pêne 1 est bloqué dans le corps 2, comme on le voit bien sur la figure 4. Dans ces conditions on peut interrompre l'alimentation en courant de l'électro-aimant 13. En d'autres termes, le pêne 1 est bloqué en position reculée dans le corps 2 et la barre 4 peut se déplacer librement.The excitation of the
On partira maintenant de la position visible sur la figure 4 pour expliquer le fonctionnement du système lorsqu'on effectue le verrouillage, et cela en s'aidant plus particulièrement des figures 5, 6 et 7.We will now start from the position visible in FIG. 4 to explain the operation of the system when performing the locking, and this with the help more particularly of FIGS. 5, 6 and 7.
Les électro-aimants 13 et 18 sont excités simultanément, ce qui permet au noyau 17 de l'électro-aimant 18 de sortir de la rainure 15 de la pièce arrière 8, comme on le voit sur la figure 5. Il est à noter ici que le ressort R₂ est comprimé, de même d'ailleurs que le ressort R₃.The
Puis, comme on le voit sur la figure 6, l'excitation de l'électro-aimant 13 est coupée, de sorte que le ressort R₂ est libéré et provoque le déplacement vers la gauche de la tige 11 et donc de l'équipage pièce 8 -pièce 9 constituant le pêne 1 qui s'engage par conséquent dans l'encoche ou gâche 3 de la barre 4. Il est à noter ici que la course de la pièce 8 du pêne 1 est stoppée par appui du talon 8a de la pièce 8 sur l'épaulement 23 du corps 2.Then, as can be seen in FIG. 6, the excitation of the
Enfin, l'excitation de l'électro-aimant 18 est interrompue, et le noyau 17 est ramené par le ressort R₃ en position d'indexage bas dans la rainure 16 de la pièce 8. On se retrouve par conséquent dans le même état que celui représenté sur la figure 1 et dans lequel le pêne 1 est bloqué, ce qui procure un verrouillage positif de la barre 4. C'est dire que toute action à l'aide d'un outil quelconque sur le pêne 1 sera sans effet.Finally, the excitation of the
On se reportera maintenant aux figures 8 et 9 pour expliquer brièvement le fonctionnement du dispositif en cas du coincement de la partie avant 9 du pêne 1 dans l'encoche 3 de la barre 4.We will now refer to FIGS. 8 and 9 to briefly explain the operation of the device in the event of the front part 9 of the bolt 1 jamming in the
Cet état est illustré sur la figure 8 où l'on voit la paroi de l'encoche 3 de la barre 4 en appui sur la partie avant 9 du pêne 1.This state is illustrated in FIG. 8 where we see the wall of the
Pour effectuer le déverrouillage, la séquence des opérations décrites à propos des figures 2 à 4 s'effectue. Autrement dit, l'état représenté sur la figure 9 correspond à celui représenté sur la figure 4, mais ici la partie avant 9 du pêne est restée en position initiale coincée dans la gâche 3, le ressort R₁ étant comprimé et l'extrémité libre de l'élément 10 étant éloignée de la butée 12, comme on le voit bien sur la figure 9. Dès qu'une action sur la barre 4 sera effectuée pour relâcher la pression de cette barre sur l'élément 10, cet élément reprendra automatiquement sa position rétractée dans le corps 2, sous l'effet du ressort R₁ qui se détendra. On se retrouvera donc dans la position visible sur la figure 4 et pour laquelle il y a déverrouillage de la barre 4.To perform the unlocking, the sequence of operations described with reference to FIGS. 2 to 4 is carried out. In other words, the state represented in FIG. 9 corresponds to that represented in FIG. 4, but here the front part 9 of the bolt remained in the initial position wedged in the
On se reportera maintenant aux figures 10 et 11 pour expliquer le fonctionnement du dispositif en cas de défaut d'alignement du pêne 1 avec la gâche 3, comme cela est bien visible sur la figure 10 où l'on voit que la barre 4 est mal positionnée par rapport à la partie avant 9 du pêne 1.We will now refer to Figures 10 and 11 to explain the operation of the device in the event of a misalignment of the bolt 1 with the
Le cycle de verrouillage peut être effectué comme expliqué à propos des figures 5 à 7, mais ici, comme on le voit sur la figure 11, l'élément 10 du pêne n'est pas engagé dans l'encoche 3 de la barre 4 et vient buter sur cette barre en étant comprimé par le ressort R₂. On voit ici que le noyau 17 de l'électro-aimant 18 prend appui sur la pièce arrière 8 du pêne 1 entre les deux rainures 15 et 16. Dès que la barre 4 sera en position adéquate, c'est-à-dire que l'encoche 3 sera en face de l'élément 10, cet élément pénétrera dans l'encoche sous l'effet de la compression du ressort R₂, et le blocage du pêne 1 sera obtenu par la pénétration du noyau 17 de l'électro-aiment 18 dans la rainure 16 de la pièce arrière 8 du pêne 1. On se retrouvera donc dans l'état visible sur la figure 7.The locking cycle can be carried out as explained with reference to FIGS. 5 to 7, but here, as can be seen in FIG. 11, the
On a donc réalisé suivant l'invention un dispositif de verrouillage et de déverrouillage qui consomme un minimum de courant électrique, qui permet d'obtenir un blocage du pêne en position verrouillée et déverrouillée, et qui remédie aux inconvénients de coincement et de défaut d'alignement du pêne vis-à-vis de l'organe à verrouiller.A locking and unlocking device has therefore been produced according to the invention which consumes a minimum of electric current, which makes it possible to obtain a locking of the bolt in the locked and unlocked position, and which overcomes the drawbacks of jamming and failure to alignment of the bolt with respect to the member to be locked.
Bien entendu, l'invention n'est nullement limitée au mode de réalisation décrit et illustré qui n'a été donné qu'à titre d'exemple.Of course, the invention is in no way limited to the embodiment described and illustrated, which has been given only by way of example.
Au contraire, l'invention comprend tous les équivalents techniques des moyens décrits, ainsi que leurs combinaisons, si celles-ci sont effectuées suivant son esprit.On the contrary, the invention includes all the technical equivalents of the means described, as well as their combinations, if these are carried out according to the spirit.
