Abstract
Description
La présente invention a pour objet un verrou destiné à être noyé dans la paroi extérieure d'un panneau ou d'une porte d'un avion, ou de tout autre véhicule pouvant aller à tres grande vitesse, et agencé de façon, d'une part, à assurer un verrouillage de grande securité, et, d'autre part, à ne provoquer qu'une résistance à l'avancement aussi minime que possible. The subject of the present invention is a lock intended to be embedded in the external wall of a panel or of a door of an airplane, or of any other vehicle which can go at very high speed, and arranged in a way on the one hand, to ensure a high security locking, and, on the other hand, to cause as little resistance to advancement as possible.
A cet effet ce verrou est du type comportant un boitier allongé, un pêne monté dans ce boîtier de façon pouvoir s'y déplacer longitudinalement et y occuper trois positions stables, une position étendue, assurant la fermeture avec verrouillage, une position intermédiaire, maintenant la fermeture, mais sans verrouillage, et une position rétractée permettant l'ouverture, une poignée longitudinale, formant levier de commande, dont la partie antérieure est montée pivotante autour d'un axe transversal prévu à la partie antérieure et supérieure du boîtier, ladite poignée de commande constituant un levier susceptible de provoquer, par son pivotement, dans un sens ou dans l'autre, le coulissement du pêne du verrou, dans un sens ou dans l'autre, et obturant entièrement, en position étendue, l'ouverture vers l'ex térieur de la partie antérieure du boîtier dans laquelle est logé le mécanisme du verrou. To this end, this lock is of the type comprising an elongated housing, a bolt mounted in this housing so as to be able to move therein longitudinally and to occupy there three stable positions, an extended position, ensuring closing with locking, an intermediate position, maintaining closing, but without locking, and a retracted position allowing the opening, a longitudinal handle, forming a control lever, the front part of which is pivotally mounted about a transverse axis provided at the front and top part of the housing, said handle control constituting a lever capable of causing, by its pivoting, in one direction or the other, the sliding of the bolt of the bolt, in one direction or the other, and completely closing, in the extended position, the opening towards the outside the front part of the housing in which the latch mechanism is housed.
Le verrou suivant la présente invention est caractérisé en ce qu'il comporte en outre un premier ressort spiral, concentrique au pêne, tendant constamment à le faire passer de sa position étendue à sa position intermédiaire, et non au-delà, un second spiral ressort, moins puissant que le premier, tendant constamment à le faire passer de sa position rétractée à sa position intermédiaire, et des moyens pour bloquer la poignée, et par conséquent le pêne qui en est solidaire, en position étendue et en position rétractée. The lock according to the present invention is characterized in that it further comprises a first spiral spring, concentric with the bolt, constantly tending to move it from its extended position to its intermediate position, and not beyond, a second spiral spring , less powerful than the first, constantly tending to move it from its retracted position to its intermediate position, and means for locking the handle, and consequently the bolt which is integral therewith, in the extended position and in the retracted position.
Le prolongement de cette poignée de commande, au-delà de son axe de pivotement, constitue un levier, comportant un galet cylindrique,librement pivotant autour d'un axe transversal porté par les deux flasques du boîtier, et susceptible de coulisser entre deux parois transversales, perpendiculaires à l'axe du coulissement du pêne, d'un coulisseau solidaire de ce dernier. The extension of this control handle, beyond its pivot axis, constitutes a lever, comprising a cylindrical roller, freely pivoting about a transverse axis carried by the two flanges of the housing, and capable of sliding between two transverse walls , perpendicular to the axis of the bolt sliding, of a slider integral with the latter.
Les dessins annexés montrent à titre d'exemple un mode de réalisation de la pressente invention
La figure 1 est une vue en coupe longitudinale montrant le pêne bloqué en position étendue, avec sa poignée de commande en position correspondante effacée dans le boiter. The accompanying drawings show by way of example an embodiment of the present invention
Figure 1 is a longitudinal sectional view showing the bolt locked in the extended position, with its control handle in the corresponding position cleared in the housing.
La figure 2 est une vue analogue, le pêne et la poignée de commande étant en position intermédiaire. Figure 2 is a similar view, the bolt and the control handle being in the intermediate position.
La figure 3 est une vue semblable, le pêne étant en position rétractée et la poignée de commande en position correspondante. Figure 3 is a similar view, the bolt being in the retracted position and the control handle in the corresponding position.
Le boîtier 1 du verrou représenté comporte deux flas- ques longitudinales parallèles 2, réunies à leur partie antérieu re par une paroi transversale 3. Le pêne 4 peut coulisser longitudinalement à l'intérieur de ce boîtier, et est guidé à cet effet par des trous de section correspondante prévus dans la paroi transversale antérieure 3, et dans les deux cloisons transversales 5 et 6, renforçant le boîtier 1, dont elles sont solidaires. The housing 1 of the lock shown comprises two parallel longitudinal flanges 2, joined at their front part by a transverse wall 3. The bolt 4 can slide longitudinally inside this housing, and is guided for this purpose by holes of corresponding section provided in the front transverse wall 3, and in the two transverse partitions 5 and 6, reinforcing the housing 1, of which they are integral.
Ce pêne 4 est lui-même solidaire en translation du coulisseau 7, comportant deux parois transversales 8 et 9 qui lui sont perpendiculaires ainsi qu'aux flasques 2 du boîtier, et sa partie arrière, constitue un épaulement 10. This bolt 4 is itself integral in translation with the slide 7, comprising two transverse walls 8 and 9 which are perpendicular thereto as well as to the flanges 2 of the housing, and its rear part, constitutes a shoulder 10.
Un premier ressort spiral 11, de faible puissance, concentrique au pêne 4, est comprimé entre la paroi transversale 9 du coulisseau 7 et la cloison transversale 6; un deuxième ressort spiral 12, plus puissant que le premier, mais de faible longueur, également concentrique au pêne 4, est monté, entre la cloison transversale 6 et l'épaulement 10 du pêne 4; le rôle et le fonctionnement de ces ressorts seront expliqués plus loin. A first spiral spring 11, of low power, concentric with the bolt 4, is compressed between the transverse wall 9 of the slide 7 and the transverse partition 6; a second spiral spring 12, more powerful than the first, but of short length, also concentric with the bolt 4, is mounted, between the transverse partition 6 and the shoulder 10 of the bolt 4; the role and operation of these springs will be explained later.
La poignée de commande 13 a une section transversale en forme de U renverse avec deux flasques 14 percées de trous per mettant son pivotement autour d'un axe 15 porté par les flasques 2 du boîtier 1; ces flasques 14 comportent des Prolongements 16, au-delà de l'axe de pivotement 15, entre lesquelles est monté librement pivotant un galet transversal 17, qui peut coulisser librement entre les deux parois latérales 3 et 9 du cl seau 7. The control handle 13 has a U-shaped cross section reverses with two flanges 14 pierced with holes per pivoting about an axis 15 carried by the flanges 2 of the housing 1; these flanges 14 include extensions 16, beyond the pivot axis 15, between which is pivotally mounted a transverse roller 17, which can slide freely between the two side walls 3 and 9 of the bucket key 7.
Le levier de verrouillage et de déclenchement 13, à section transversale également en forme de U renversé, est monté pivotant autour d'un axe transversal 19, solidaire des flasques 14 de la poignée de commande 13; il est constamment sollicitee par un ressort 20, en forme d'épingle, monté autour de l'axe précité 19, qui le maintient en position effacée- dans laquelle il complete la paroi supérieure transversale de la poignée de commande 13 dont il obture entièrement la découpe permettant de l'y loger. Son pivotement vers le haut, sous la poussée de la branche antérieure 21 du ressort en epingle 20 est limité du fait que sa partie arrière vient buter sur la branche postérieure 22 dudit ressort 20. The locking and triggering lever 13, also of inverted U-shaped cross section, is pivotally mounted about a transverse axis 19, integral with the flanges 14 of the control handle 13; it is constantly stressed by a spring 20, in the form of a pin, mounted around the aforementioned axis 19, which keeps it in the retracted position - in which it completes the upper transverse wall of the control handle 13 from which it completely closes the cutout to accommodate it. Its pivoting upwards, under the thrust of the front branch 21 of the pin spring 20 is limited because its rear part abuts on the rear branch 22 of said spring 20.
Les bords antérieurs 23 des flasques de ce levier de verrouillage 18 sont découpes de façon à former des crochets 25 susceptibles de coopérer avec une tige transversale 26 portée par les flasques 2 du boîtier 1. The front edges 23 of the flanges of this locking lever 18 are cut so as to form hooks 25 capable of cooperating with a transverse rod 26 carried by the flanges 2 of the housing 1.
Le fonctionnement est le suivant
Dans la position du pene étendu, tel que montre dans la figure 1, celui-ci est verrouillé du fait, que le galet transversal 17, porte' par le prolongement 16 formant levier, de la poignée de commande 13 est bloqué dans la position représentée par llaxe transversal 26 engagé dans les crochets 25 du levier de verrouillage et de déclenchement 18, et que la paroi transversale antérieure 8 du coulisseau 7 vient en batée contre ce galet sous l'action de la traction exercée sur lui par le ressort 12, plus puissant que le ressort 11 agissant en sens inverse.The operation is as follows
In the position of the extended bolt, as shown in FIG. 1, this is locked because the transverse roller 17, carried by the lever-forming extension 16, of the control handle 13 is locked in the position shown by the transverse pin 26 engaged in the hooks 25 of the locking and triggering lever 18, and that the front transverse wall 8 of the slide 7 is beating against this roller under the action of the traction exerted on it by the spring 12, more as powerful as the spring 11 acting in the opposite direction.
Pour débloquer ce verrou, on exerce une pression sur la partie antérieure 27, moletée, de la paroi supérieure du levier de verrouillage et de déclenchement 18, à l'encontre de la force antagoniste du ressort en épingle 20, et on provoque son pivotement autour de l'axe 18, ce qui a pour effet de dégager ses crochets 25 de la tige transversale 26; la puissance du ressort 12, exerçant une poussée sur l'épaulement arrière 10 du pêne 4 entraîne celui-ci vers l'arrière, en comprimant le ressort moins puissant 11. To unlock this lock, pressure is exerted on the knurled front part 27 of the upper wall of the locking and release lever 18, against the opposing force of the pin spring 20, and it is pivoted around axis 18, which has the effect of releasing its hooks 25 from the transverse rod 26; the power of the spring 12, pushing on the rear shoulder 10 of the bolt 4 drives the latter backwards, compressing the less powerful spring 11.
Pour amorcer le pivotement vers le haut de la poignée de manoeuvre 13, après avoir fait pivoter vers le bas le levier 2 de verrouillage et de déplacement 18 et dégagé ainsi les crochets 25 de la tige 26, on a prévu un poussoir 27, ronstamment sollicité vers le haut par le ressort spiral concentrique 28 prenant appui sur une plaque transversale 29, en forme de U, que traverse ce poussoir, qui comporte à cet effet une tête 30, de plus grand diamètre, sur la face inférieure de laquelle la partie supérieure du ressort 28 exerce une poussée qui peut amorcer le pivotement vers le haut, désiré de la commande 13. To initiate the upward pivoting of the operating handle 13, after having pivoted the locking and displacement lever 2 downwards 18 and thus released the hooks 25 from the rod 26, a pusher 27 has been provided, which is constantly stressed upwards by the concentric spiral spring 28 bearing on a transverse plate 29, in the shape of a U, through which this pusher passes, which for this purpose comprises a head 30, of larger diameter, on the lower face of which the upper part of the spring 28 exerts a thrust which can initiate the upward pivoting, desired of the control 13.
Sous l'action du ressort 12, les différents organes du verrou arrivent alors dans la position représentée à la figure 2 dans laquelle les forces exercées en sens inverses sur le pne 4 par les deux ressorts 11 et 12, s'équilibrent. Under the action of the spring 12, the various members of the bolt then arrive in the position shown in FIG. 2 in which the forces exerted in opposite directions on the pin 4 by the two springs 11 and 12 are balanced.
Pour déverrouiller, et permettre ensuite l'ouverture du panneau ou de la porte sur lequel ce verrou est monté, on fait pivoter la poignée de commande 13 vers le haut, autour de son axe de pivotement 15, à l'encontre du ressort antagoniste de faible puissance 11, jusqu'à ce que ces différents organes arrivent dans la position représentée dans la figure 3; ils sont bloqués dans ces positions du fait que le galet 17 est alors engagé dans la dépression 31 prévue à cet effet dans la face antérieure de la paroi transversale 9 du coulisseau 7 et y est maintenu par la pression du ressort 11. To unlock, and then allow the opening of the panel or door on which this lock is mounted, the control handle 13 is pivoted upwards, around its pivot axis 15, against the opposing spring of low power 11, until these various members arrive in the position shown in Figure 3; they are locked in these positions because the roller 17 is then engaged in the depression 31 provided for this purpose in the front face of the transverse wall 9 of the slide 7 and is held there by the pressure of the spring 11.
Deux tronçons tubulaires 32 et 33, entretoisant les flasques 2 du boitier 1, le renforcent et le rigidifient. Two tubular sections 32 and 33, bracing the flanges 2 of the housing 1, strengthen it and stiffen it.
I1 est bien entendu que le mode de réalisation de l'invention qui a été décrit ci-dessus en référence au dessin annexé, a été donné à titre purement indicatif et nullement limitatif et que de nombreuses modifications peuvent être apportés sans qu'on s'écarte pour cela du cadre de la présente invention It is understood that the embodiment of the invention which has been described above with reference to the appended drawing, has been given for information only and is in no way limitative and that numerous modifications can be made without being for this purpose deviates from the scope of the present invention
