Description

L'invention concerne un dispositif de verrouillage d'un panneau mobile à double sécurité.The invention relates to a device for locking a mobile double security panel.

Plus précisément, l'invention concerne un dispositif de verrouillage d'un panneau mobile qui comporte un dispositif d'immobilisation dans les trois axes d'un panneau verrouillé incorporé dans le mécanisme de verrouillage à double sécurité ainsi qu'un indicateur très apparent de la position correctement verrouillée.More specifically, the invention relates to a device for locking a movable panel which comprises a device for immobilizing in the three axes of a locked panel incorporated in the double security locking mechanism as well as a very apparent indicator of the position correctly locked.

Les dispositifs connus de verrouillage, pour des panneaux mobiles tels que des capots de moteur d'aérodyne ne donnent pas entière satisfaction parce qu'ils n'assurent pas de façon positive l'immobilisation du capot par rapport à la structure d'appui. De ce fait, les vibrations amènent fréquemment des détériorations et des jeux qui conduisent à des ouvertures intempestives en vol, et par conséquent à de graves risques d'accident. L'invention concerne un dispositif de verrouillage qui s'oppose à l'ouverture du panneau mobile et l'immobilise dans les trois axes interdisant ainsi les déplacements induits par les vibrations qui seraient la cause de détérioration par usure, frottement, matage, etc... Il comporte un système de sécurité qui, en cas de défaillance du verrouillage, interdit l'ouverture du panneau. Il permet en outre à l'opérateur de s'assurer sans ambiguité que le verrouillage est complet.Known locking devices for mobile panels such as engine hoods of an aerodyne are not entirely satisfactory because they do not positively immobilize the hood relative to the support structure. As a result, the vibrations frequently cause deterioration and play which lead to inadvertent openings in flight, and consequently to serious risks of accident. The invention relates to a locking device which opposes the opening of the movable panel and immobilizes it in the three axes, thus preventing displacements induced by vibrations which would be the cause of deterioration by wear, friction, dulling, etc. .. It has a security system which, in the event of a lock failure, prevents the panel from being opened. It also allows the operator to unambiguously ensure that the locking is complete.

Ces fonctions sont assurées conformément à l'invention par la présence, dans le dispositif de verrouillage, de moyens d'immobilisation du panneau dans son plan et de moyens assurant son maintien en position verrouillée dans une direction perpendiculaire à ce plan, les moyens d'immobilisation étant constitués par une platine solidaire du panneau et comportant un trou conique et par une butée conique solidaire de la structure fixe et qui pénètre dans le trou de la platine lorsque le panneau est en position fermée, les moyens de maintien en position verrouillée étant constitués par une gâche ou rebord de verrouillage solidaire de la structure fixe, par un support monté sur le panneau, par un pêne monté pivotant sur le support et apte à s'engager dans la gâche lorsque le panneau est en position fermée, des moyens élastiques sollicitant le pêne vers la position dégagée de la gâche, par une gâchette montée pivotante sur le support et apte à verrouiller le pêne dans la position engagée, des moyens élastiques sollicitant la gâchette dans la position de verrouillage.These functions are provided in accordance with the invention by the presence, in the locking device, of means for immobilizing the panel in its plane and of means ensuring its maintenance in the locked position in a direction perpendicular to this plane, the means of immobilization being constituted by a plate secured to the panel and comprising a conical hole and by a conical stop secured to the fixed structure and which penetrates into the hole of the plate when the panel is in the closed position, the means for holding in the locked position being constituted by a keeper or locking rim secured to the fixed structure, by a support mounted on the panel, by a bolt pivotally mounted on the support and capable of engaging in the keeper when the panel is in the closed position, elastic means urging the bolt towards the released position of the strike, by a trigger pivotally mounted on the support and able to lock the bolt in the engaged position, elastic means urging the trigger in the locked position.

L'invention présente l'avantage d'immobiliser le panneau articulé dans les trois axes, d'absorber les déplacements induits par les vibrations et de ne pas créer de contraintes dans le panneau lors de sa fermeture.The invention has the advantage of immobilizing the articulated panel in the three axes, of absorbing the displacements induced by vibrations and of not creating stresses in the panel when it is closed.

Selon une caractéristique préférentielle, le dispositif comporte des moyens de verrouillage de sécurité du pêne et d'indication visuelle de position verrouillée de l'ensemble du dispositif. Ces moyens sont constitués par un cache de sécurité monté pivotant sur le support, ce cache étant apte à empêcher la manoeuvre du pêne et de la gâchette, cache qui ne peut être rabattu que si le pêne et la gâchette sont en position verrouillée.According to a preferred characteristic, the device comprises means for locking the bolt safety and for visual indication of the locked position of the entire device. These means consist of a safety cover pivotally mounted on the support, this cover being able to prevent the operation of the bolt and the trigger, a cover which can only be folded down if the bolt and the trigger are in the locked position.

L'invention est exposée ci-après plus en détail à l'aide de dessins représentant seulement un mode d'exécution.

  • - la figure 1 représente une vue latérale, en position ouverte, d'un dispositif de verrouillage de panneau mobile à double sécurité conforme à l'invention,
  • - la figure 2 représente le mécanisme de verrouillage de la figure 1 en position fermée,
  • - la figure 2a est une vue schématique en coupe du panneau mobile sur lequel est fixée la platine,
  • - la figure 3 est une vue de dessus en coupe selon la ligne III-III de la figure 1 du mécanisme de verrouillage représenté sur les figures 1 et 2, le cache étant en position relevée,
The invention is set out below in more detail with the aid of drawings representing only one embodiment.
  • FIG. 1 represents a side view, in the open position, of a double security mobile panel locking device according to the invention,
  • FIG. 2 represents the locking mechanism of FIG. 1 in the closed position,
  • FIG. 2a is a schematic sectional view of the movable panel on which the plate is fixed,
  • FIG. 3 is a top view in section along line III-III of FIG. 1 of the locking mechanism shown in FIGS. 1 and 2, the cover being in the raised position,

Sur la figure 1, la référence 2 désigne une structure telle que par exemple une cellule d'hélicoptère ou d'avion. Un capot 4 est articulé sur la cellule 2 par une articulation 6. Le capot 4 est par exemple un panneau ouvrant, un capotage de moteur, un portillon.In FIG. 1, the reference 2 designates a structure such as for example a helicopter or airplane cell. A cover 4 is articulated on the cell 2 by an articulation 6. The cover 4 is for example an opening panel, an engine cowling, a gate.

La structure fixe 2 comporte un montant 7 à la partie supérieure duquel on a réalisé un rebord de verrouillage ou gâche 8. A la partie supérieure du montant 7, sur sa face externe on trouve une butée conique 10 en élastomère, fixée sur le montant au moyen d'une vis et d'un écrou. L'alésage 9 pratiqué dans le montant possède un diamètre supérieur au diamètre de la vis, ce qui permet le réglage du dispositif de verrouillage en agissant sur la position de la butée dont l'axe est monté avec le jeu nécessaire dans l'alésage 9 pratiqué dans le montant.The fixed structure 2 comprises an upright 7 at the upper part of which a locking rim or keeper 8 has been produced. At the upper part of the upright 7, on its outer face there is a conical stopper 10 made of elastomer, fixed on the upright by means of a screw and a nut. The bore 9 in the upright has a diameter greater than the diameter of the screw, which allows the adjustment of the locking device by acting on the position of the stop whose axis is mounted with the necessary clearance in the bore 9 practiced in the amount.

Le dispositif de verrouillage comporte une platine 11. Cette platine se présente sous la forme d'une plaque mince, par exemple une tôle d'acier, de forme générale rectangulaire et comportant une fenêtre centrale rectangulaire. A sa partie supérieure, elle comporte un rebord llb qui sert à la fixation d'un ressort comme cela sera expliqué ultérieurement. A sa partie inférieure, elle comporte un trou conique lla à bord tombé. L'angle du cône est par exemple de 60°. Le trou lla s'adapte à la butée conique 10. La butée sert à l'immobilisation du dispositif avant verrouillage. La platine 11 vient s'encastrer sur la butée grâce au trou lla et immobilise le panneau mobile 4 dans son plan. La platine est fixée sur le panneau mobile 4 par quatre boulons dont deux ont été schématisés par les traits d'axe 12 sur les figures 2a et 3.The locking device comprises a plate 11. This plate is in the form of a thin plate, for example a sheet of steel, of generally rectangular shape and comprising a central rectangular window. At its upper part, it has a flange llb which is used for fixing a spring as will be explained later. At its lower part, it has a conical hole lla with a fallen edge. The angle of the cone is for example of 60 °. The hole lla adapts to the conical stop 10. The stop serves to immobilize the device before locking. The plate 11 comes to be embedded on the stop thanks to the hole lla and immobilizes the movable panel 4 in its plane. The plate is fixed to the movable panel 4 by four bolts, two of which have been shown diagrammatically by the axis lines 12 in FIGS. 2a and 3.

Un boîtier ou support 13 s'engage dans la fenêtre rectangulaire pratiquée dans la platine 11 sur laquelle il s'appuie par des rebords latéraux 13a représentés sur les figures 2a et 3. Le support 13 est fixé à l'ensemble platine-panneau mobile 4 par les mêmes boulons 12 et assure la fixation de la platine sur le panneau, comme on peut le voir particulièrement sur les figures 2a et 3.A box or support 13 engages in the rectangular window made in the plate 11 on which it is supported by lateral flanges 13a shown in FIGS. 2a and 3. The support 13 is fixed to the plate-mobile panel assembly 4 by the same bolts 12 and ensures the fixing of the plate on the panel, as can be seen particularly in FIGS. 2a and 3.

Un pêne 14 est monté pivotant sur le support 13 par l'intermédiaire d'un axe 15. Le pêne comporte une première surface 14a de retenue du capot destinée à venir en contact avec le rebord de verrouillage 8, une deuxième surface 14b de verrouillage du pêne et une troisième surface 14c de verrouillage de sécurité. Il comporte également une poignée de commande 14d qui permet de le pousser vers le haut en position fermée.A bolt 14 is pivotally mounted on the support 13 by means of an axis 15. The bolt comprises a first surface 14a for retaining the cover intended to come into contact with the locking flange 8, a second surface 14b for locking the bolt and a third safety locking surface 14c. It also has a control handle 14d which makes it possible to push it upwards in the closed position.

Une gâchette 18 est montée pivotante sur le support 13 par-l'intermédiaire d'un axe 16 parallèle à l'axe 15. Comme on peut le voir sur la figure 3, la gâchette 18 comporte en réalité deux parties symétriques par rapport à l'axe de symétrie du dispositif de verrouillage et situées de part et d'autre du pêne 14. Ces deux parties sont reliées l'une à l'autre par une barre transversale 18c (voir figure 2). Chaque partie symétrique comporte une surface de verrouillage 18a apte à coopérer avec la surface 14b de verrouillage du pêne. Cette surface a la forme d'une encoche. Lorsque le dispositif de verrouillage est en position fermée, comme représenté sur la figure 2, la surface 14b est engagée dans l'encoche 18a de la gâchette. Par ailleurs, chaque partie symétrique comporte une surface d'actionnement 18b qui permet de la faire pivoter manuellement de l'extérieur autour de son axe 16 par une action dirigée selon le sens de la flèche 32 (figure 2). Les surface 18b sont striées pour faciliter le déverrouillage.A trigger 18 is pivotally mounted on the support 13 by means of an axis 16 parallel to the axis 15. As can be seen in FIG. 3, the trigger 18 actually comprises two parts symmetrical with respect to the 'axis of symmetry of the locking device and located on either side of the bolt 14. These two parts are connected to each other by a crossbar 18c (see Figure 2). Each symmetrical part comprises a locking surface 18a able to cooperate with the worm surface 14b rusting the bolt. This surface has the shape of a notch. When the locking device is in the closed position, as shown in Figure 2, the surface 14b is engaged in the notch 18a of the trigger. Furthermore, each symmetrical part has an actuating surface 18b which makes it possible to manually rotate it from the outside around its axis 16 by an action directed in the direction of the arrow 32 (FIG. 2). The surfaces 18b are striated to facilitate unlocking.

Des moyens élastiques de rappel sont prévus pour solliciter le pêne 14 en position ouverte, c'est-à-dire pour l'entraîner en rotation dans le sens des aiguilles d'une montre sur les figures 1 et 2. Des moyens élastiques de rappel sont également prévus pour entraîner en rotation la gâchette 18 dans le sens de rotation des aiguilles d'une montre sur les figures 1 et 2. Dans le mode de réalisation décrit, ces moyens élastiques sont constitués par un ressort de sécurité unique 20 ayant une action de rappel élastique à la fois sur le pêne et sur la gâchette.Elastic return means are provided to urge the bolt 14 in the open position, that is to say to drive it in rotation clockwise in FIGS. 1 and 2. Elastic return means are also provided for rotating the trigger 18 in the direction of rotation of the needles of a watch in FIGS. 1 and 2. In the embodiment described, these elastic means consist of a single safety spring 20 having an action elastic return on both the bolt and the trigger.

Le dispositif de verrouillage comporte également des moyens de verrouillage de sécurité. Ces moyens sont constitués par un cache de sécurité 22 monté pivotant autour d'une charnière 24 solidaire du support 13 (voir figure 3) et dont l'axe est parallèle aux axes 15 et 16. Un ressort à lame 25 fixé au rebord llb de la platine 11 maintient le cache 22 en position ouverte ou fermée. Dans sa position fermée, le cache repose sur la butée conique 10. Il comporte une fenêtre en forme de T inversé 22a, dont le bord inférieur 22b (voir figure 3) coopère avec la surface 14c du pêne pour verrouiller ce dernier en position fermée lorsque le cache est rabattu, comme représenté sur la figure 2. Les surfaces 22a empêchent le pivotement de la gâchette lorsque le cache est rabattu. La face interne du cache est peinte d'une couleur voyante, par exemple en rouge vif.The locking device also includes safety locking means. These means consist of a safety cover 22 pivotally mounted around a hinge 24 integral with the support 13 (see Figure 3) and whose axis is parallel to the axes 15 and 16. A leaf spring 25 fixed to the flange llb of the plate 11 maintains the cover 22 in the open or closed position. In its closed position, the cover rests on the conical stop 10. It has a window in the shape of an inverted T 22a, the lower edge 22b of which (see FIG. 3) cooperates with the surface 14c of the bolt to lock the latter in the closed position when the cover is folded down, as shown in Figure 2. The surfaces 22a prevent pivoting of the trigger when the cover is folded down. The inner face of the cover is painted in a conspicuous color, for example bright red.

Pour déverrouiller le mécanisme, il faut d'abord soulever le cache 22 en le faisant pivoter autour de son axe de rotation suivant le sens de la flèche 30 pour l'amener dans la position représentée sur la figure 1. Ceci fait, on agit sur la surface de commande 18b de la gâchette, comme schématisé par la flèche 32. Cette action fait pivoter la gâchette autour de son axe, comme représenté par la flèche 26, et libère le pêne qui pivote selon le sens de la flèche 34 sous l'effet des moyens élastiques de rappel. On peut alors soulever le capot comme indiqué par la flèche en traits pointillés 36.To unlock the mechanism, first lift the cover 22 by rotating it around its axis of rotation in the direction of the arrow 30 to bring it into the position shown in Figure 1. This done, we act on the control surface 18b of the trigger, as shown diagrammatically by the arrow 32. This action makes the trigger rotate around its axis, as represented by the arrow 26, and releases the bolt which pivots in the direction of the arrow 34 under the effect of elastic return means. The hood can then be lifted as indicated by the arrow in dotted lines 36.

Le verrouillage s'effectue en ordre inverse. Le volet 4 étant en position fermée et appliqué en contact avec la butée conique 10, on agit sur la poignée de commande 14d du pêne de manière à faire pivoter celui-ci dans le sens inverse de la flèche 34 jusqu'à l'accrochage de la gâchette 18. Le pêne est alors maintenu en position verrouillée, comme représenté sur la figure 2. Si le mouvement n'a pas été effectué à fond, il revient automatiquement dans la position représentée sur la figure 1 ; un verrouillage incomplet est donc visible sans ambiguïté. Si le verrouillage a été effectué complètement, on rabat le cache de sécurité 22. Celui-ci est maintenu fermé sous l'action du ressort à lame 25. Dans cette position, toute action sur la partie striée 18b de la gâchette ou sur le pêne 14 est sans effet sur le mécanisme.Locking takes place in reverse order. The shutter 4 being in the closed position and applied in contact with the conical stop 10, action is taken on the control handle 14d of the bolt so as to pivot the latter in the opposite direction to the arrow 34 until the hooking of the trigger 18. The bolt is then kept in the locked position, as shown in FIG. 2. If the movement has not been carried out fully, it automatically returns to the position shown in FIG. 1; an incomplete locking is therefore visible without ambiguity. If the locking has been carried out completely, the safety cover 22 is folded down. The latter is kept closed under the action of the leaf spring 25. In this position, any action on the striated part 18b of the trigger or on the bolt 14 has no effect on the mechanism.

Ainsi, le dispositif de verrouillage de l'invention réalise la combinaison d'un organe de fixation unique de l'immobilisation d'un panneau mobile par rapport à une structure fixe suivant trois axes avec, d'une part, un verrouillage à double sécurité de la fermeture et, d'autre part, l'indication visuelle apparente d'un bon verrouillage.Thus, the locking device of the invention achieves the combination of a single fixing of the immobilization of a movable panel with respect to a fixed structure along three axes with, on the one hand, a double safety locking of the closure and, on the other hand, the apparent visual indication of a good locking.
