Description

L'invention concerne un dispositif à bouton-poussoir pour la commande d'une serrure, par exemple d'une serrure de porte ou de capot de véhicule automobile.The invention relates to a push-button device for controlling a lock, for example a door or hood lock of a motor vehicle.

Les dispositifs de ce genre comportent habituellement, non seulement un bouton-poussoir de commande du déplacement axial d'une palette radiale propre à entraîner un organe d'ouverture de la serrure, mais également un barillet de serrure susceptible de tourner dans le bouton-poussoir sous l'action d'une clé adaptée et d'entraîner la palette entre une position de verrouillage et une position active. Dans cette dernière position, la palette peut être déplacée par le bouton-poussoir contre l'action d'un ressort de rappel qui tend, à chaque instant, à repousser ce dernier vers l'extérieur.Devices of this kind usually include not only a push button for controlling the axial movement of a radial pallet capable of driving a member for opening the lock, but also a lock cylinder capable of turning in the push button. under the action of a suitable key and to drive the pallet between a locking position and an active position. In this last position, the pallet can be moved by the push button against the action of a return spring which tends, at all times, to push the latter outwards.

En conséquence, le bouton reste toujours proéminent, ce qui présente l'inconvénient de ne pas permettre à l'utilisateur de savoir si le dispositif est verrouillé ou non, le bouton étant toujours dans la même position, et en outre de fournir un obstacle extérieur qui risque de blesser un piéton ou un passager, et de laisser prise à un outil, par exemple une pince, dans le but de forcer la serrure.Consequently, the button always remains prominent, which has the disadvantage of not allowing the user to know whether the device is locked or not, the button being always in the same position, and in addition to providing an external obstacle. which could injure a pedestrian or a passenger, and allow a tool, for example pliers, to get caught in order to force the lock.

Pour éviter ces inconvénients il a été proposé de munir le barillet d'un doigt radial coopérant avec une lumière hélicoïdale formée dans une portion tubulaire d'une pièce fixe, par exemple d'un corps fixe de guidage du bouton-poussoir. Toutefois le frottement du doigt contre les bords de la lumière provoque une dureté de manoeuvre et une usure indésirables et, à moins que le doigt ne soit très petit, donc peu fiable, la portion tubulaire comportant la lumière hélicoïdale doit être relativement encombrante, ce qui rend difficile le montage du dispositif équipé de la palette par engagement et centrage du corps fixe dans une ouverture d'un panneau.To avoid these drawbacks, it has been proposed to provide the barrel with a radial finger cooperating with a helical opening formed in a tubular portion of a fixed part, for example of a fixed body for guiding the push button. However, the friction of the finger against the edges of the light causes unwanted hardness of operation and wear and, unless the finger is very small, therefore unreliable, the tubular portion comprising the helical light must be relatively bulky, which makes it difficult to mount the device equipped with the pallet by engagement and centering of the fixed body in an opening of a panel.

La présente invention a pour but de remédier à cet inconvénient en réalisant une commande de serrure à bouton-poussoir dans laquelle le bouton-poussoir puisse être maintenu enfoncé tant que le dispositif est verrouillé, et qui soit simple, fiable et peu encombrante.The object of the present invention is to remedy this drawback by providing a push-button lock control in which the push-button can be kept pressed as long as the device is locked, and which is simple, reliable and compact.

Cette invention a pour objet un dispositif de commande de serrure comportant, dans un corps fixe cylindrique, un bouton-poussoir coulissant de commande du déplacement axial d'une palette radiale d'actionnement de la serrure; un barillet de serrure qui tourne dans le bouton-poussoir tout en en étant solidaire axialement et qui porte la palette et la fait pivoter entre une position de verrouillage, pour laquelle elle est écartée d'un organe d'ouverture, et une position déverrouillée ou active, pour laquelle elle est en regard de cet organe; et des moyens d'entraînement en translation du bouton-poussoir dans le corps fixe, lors de la rotation du barillet; dispositif qui en outre comporte, fixé à l'extrémité du barillet portant la palette, un embout tubulaire dont la paroi latérale est partiellement échancrée et forme une rampe hélicoïdale aboutissant à son bord extrême le plus éloigné de la palette, et, sur le corps fixe, une portion de cylindre en saillie ayant un contour complémentaire de celui de l'échancrure de l'embout et formant une rampe hélicoïdale propre à coopérer avec celle du barillet en vue du déplacement axial du bouton-poussoir dans le corps fixe, lors de la rotation du barillet.The subject of this invention is a lock control device comprising, in a cylindrical fixed body, a sliding push button for controlling the axial movement of a radial pallet for actuating the lock; a lock barrel which rotates in the push button while being axially integral therewith and which carries the pallet and makes it rotate between a locking position, for which it is spaced from an opening member, and an unlocked position or active, for which it is opposite this organ; and means for driving the push button in translation in the fixed body, during the rotation of the barrel; device which further comprises, fixed to the end of the barrel carrying the pallet, a tubular end-piece whose side wall is partially indented and forms a helical ramp leading to its extreme edge furthest from the pallet, and, on the fixed body , a projecting cylinder portion having a contour complementary to that of the notch of the end piece and forming a helical ramp capable of cooperating with that of the barrel for the axial movement of the push button in the fixed body, during the barrel rotation.

Selon un mode de réalisation préféré, la rampe hélicoïdale du corps fixe est terminée, en regard de l'embout, par une surface extrême transversale d'appui du bord extrême de l'embout en position de verrouillage et d'enfoncement du bouton-poussoir.According to a preferred embodiment, the helical ramp of the fixed body is terminated, facing the end piece, by an extreme transverse surface for bearing on the end edge of the end piece in the locking and push-in position of the push button. .

Dans un tel dispositif le bouton-poussoir est automatiquement enfoncé par le déplacement en rotation du barillet vers la position de verrouillage et il est maintenu dans cette position par le contact de la surface extrême d'appui et du bord extrême de l'embout.In such a device the push button is automatically pressed by the rotation movement from the barrel to the locking position and it is held in this position by contacting the end support surface and the end edge of the end piece.

Par ailleurs, l'embout tubulaire et la portion de cylindre forment deux parties complémentaires qui s'emboîtent l'une dans l'autre lorsque le bouton-poussoir est en saillie à l'extérieur et présentent ainsi un encombrement minimal.Furthermore, the tubular end piece and the cylinder portion form two complementary parts which fit into one another when the push-button protrudes outside and thus have a minimal bulk.

De préférence, en position déverrouillée, c'est-à-dire en position sortie du bouton-poussoir, les rampes hélicoïdales de l'embout tubulaire et de la portion de cylindre du corps fixe sont espacées d'une distance qui correspond au déplacement angulaire de dégagement de la palette par rapport à l'organe d'ouverture de la serrure.Preferably, in the unlocked position, that is to say in the extended position of the push button, the helical ramps of the tubular end piece and of the cylinder portion of the fixed body are spaced by a distance which corresponds to the angular displacement. of release of the pallet relative to the opening member of the lock.

Selon une autre caractéristique, l'échancrure comporte un bord longitudinal qui, en position déverrouillée, bute contre un bord correspondant de la saillie.According to another characteristic, the notch has a longitudinal edge which, in the unlocked position, abuts against a corresponding edge of the projection.

Ainsi, le bouton-poussoir étant en saillie en position déverrouillée, et enfoncé en position de verrouillage, celui-ci est visualisé avec précision et sécurité.Thus, the push-button protruding in the unlocked position, and pressed in the locked position, it is viewed with precision and security.

En outre le dispositif est facile à introduire dans l'ouverture d'une paroi et à centrer dans celle-ci.In addition, the device is easy to introduce into the opening of a wall and to center therein.

La description ci-dessous d'un mode de réalisation donné à titre d'exemple non limitatif, et représenté aux dessins annexés, fera d'ailleurs ressortir les avantages et caractéristiques de l'invention.The description below of an embodiment given by way of nonlimiting example, and represented in the appended drawings, will moreover highlight the advantages and characteristics of the invention.

Le dispositif de commande par bouton-poussoir objet de l'invention comporte un corps extérieur 1 de fixation sur une paroi 2 par tout moyen connu, et notamment par l'intermédiaire d'une collerette 4. Le corps 1 a de préférence une forme tubulaire et son diamètre extérieur correspond sensiblement à celui de l'ouverture 5 de la paroi, dans laquelle il est monté.The push-button control device which is the subject of the invention comprises an external body 1 for fixing to a wall 2 by any known means, and in particular by means of a flange 4. The body 1 preferably has a tubular shape and its outside diameter corresponds substantially to that of the opening 5 of the wall, in which it is mounted.

A l'intérieur du corps 1 coulisse un bouton-poussoir tubulaire 6. Ce bouton comporte une partie de plus petit diamètre extérieur, qui forme un épaulement externe 7 (fig. 3) et délimite, avec le corps 1, un logement 8 pour un ressort 9 en appui, d'une part sur l'épaulement 7 du bouton-poussoir et, d'autre part, sur un rebord interne 10 de l'extrémité du corps 1. Le ressort 9 tend à repousser le bouton 6 vers l'extérieur du corps 1 et de la paroi 2, c'est-à-dire à appliquer une bague élastique 12, fixée dans une gorge du bouton-poussoir 6, contre le rebord 10 du corps 1.Inside the body 1 slides a tubular push button 6. This button has a part of smaller outside diameter, which forms an external shoulder 7 (fig. 3) and delimits, with the body 1, a housing 8 for a spring 9 rests, on the one hand on the shoulder 7 of the push button and, on the other hand, on an internal rim 10 of the end of the body 1. The spring 9 tends to push the button 6 towards the outside of the body 1 and of the wall 2, that is to say applying an elastic ring 12, fixed in a groove of the push button 6, against the flange 10 of the body 1.

Le bouton 6 comporte une rainure longitudinale extérieure 14 dans laquelle coulisse une saillie 16 du rebord 10, immobilisant le bouton 6 en rotation tout en guidant son déplacement axial.The button 6 has an external longitudinal groove 14 in which slides a projection 16 of the rim 10, immobilizing the button 6 in rotation while guiding its axial movement.

Dans un alésage axial du bouton 6 est emmanché un barillet de serrure, sensiblement cylindrique, représenté schématiquement en 18, qui est susceptible de tourner sous l'action d'une clé adaptée, d'une manière connue qui n'a pas été représentée pour ne pas compliquer le dessin. Le barillet 18 comporte, à son extrémité externe, un épaulement 19 en butée contre une face radiale 20 d'un évidement annulaire du bouton-poussoir et, à son extrémité interne, un ergot 21 de section non circulaire, qui, dans le mode de réalisation représenté, a une forme carrée. Cet ergot 21 est traversé par une vis à embase large 23, qui serre contre le barillet une palette radiale 22 d'actionnement d'un organe d'ouverture d'une serrure, représenté schématiquement en 24 sur la figure 1.In an axial bore of the button 6 is fitted a lock cylinder, substantially cylindrical, shown diagrammatically at 18, which is capable of turning under the action of an adapted key, in a known manner which has not been shown for do not complicate the drawing. The barrel 18 has, at its outer end, a shoulder 19 abutting against a radial face 20 of an annular recess of the push button and, at its end internal, a lug 21 of non-circular section, which, in the embodiment shown, has a square shape. This lug 21 is crossed by a wide flange screw 23 which clamps against the barrel a radial pallet 22 for actuating an opening member of a lock, shown diagrammatically at 24 in FIG. 1.

Le barillet 18 porte en outre un embout tubulaire de forme générale cylindrique, 26, ouvert à l'une de ses extrémités et comportant un fond 27, percé d'un trou central et emmanché sur l'ergot 21, qui est serré autour de cet ergot, entre le barillet 18 et la palette 22 par la vis 23. L'embout 26 est ainsi étroitement solidaire du barillet 18 et de la palette 22, à la fois en rotation et en translation.The barrel 18 further carries a tubular endpiece of generally cylindrical shape, 26, open at one of its ends and comprising a bottom 27, pierced with a central hole and fitted on the lug 21, which is tightened around this lug, between the barrel 18 and the pallet 22 by the screw 23. The endpiece 26 is thus closely secured to the barrel 18 and the pallet 22, both in rotation and in translation.

La paroi latérale de l'embout 26 comporte une échancrure qui est délimitée par une rampe hélicoïdale 28 aboutissant, d'une part au bord 30 de l'extrémité ouverte de l'embout et, d'autre part, à une surface transversale 32 sensiblement parallèle au fond 27. Une face longitudinale 34, parallèle à l'axe de l'embout, relie la surface 32 au bord extrême 30.The side wall of the endpiece 26 has a notch which is delimited by a helical ramp 28 leading, on the one hand to the edge 30 of the open end of the endpiece and, on the other hand, to a transverse surface 32 substantially parallel to the bottom 27. A longitudinal face 34, parallel to the axis of the end piece, connects the surface 32 to the extreme edge 30.

En regard de l'échancrure de l'embout 26 le corps fixe 1 est muni d'une saillie 36 ayant un contour voisin de celui de l'échancrure. La saillie 36 est délimitée par une rampe hélicoïdale 38, de forme complémentaire de celle de la rampe 28, qui se termine en regard de l'embout 26 par une surface transversale 40 réunissant la rampe 38 à un bord longitudinal 42. Cette saillie 36 est, de préférence, une portion de cylindre d'épaisseur constante, dont le diamètre extérieur est le même que celui de l'embout 26.Opposite the notch of the end piece 26 the fixed body 1 is provided with a projection 36 having a contour close to that of the notch. The projection 36 is delimited by a helical ramp 38, of shape complementary to that of the ramp 28, which ends opposite the end piece 26 by a transverse surface 40 joining the ramp 38 to a longitudinal edge 42. This projection 36 is preferably a portion of a cylinder of constant thickness, the outside diameter of which is the same as that of the end piece 26.

Le diamètre intérieur de l'embout 26 est, lui, légèrement supérieur au diamètre extérieur d'une partie cylindrique 44 du corps fixe 1 qui porte la saillie 36, et il entoure cette partie 44, comme le montre la figure 1, lorsque le bouton-poussoir 6 est repoussé à l'extérieur de la paroi 2 par le ressort 9. La portion de cylindre 36 du corps 1 est alors pratiquement emboîtée dans l'échancrure de l'embout 26, le bord 42 étant en butée contre la face correspondante 34 de cet embout. Toutefois, la surface transversale 32 de l'embout étant plus longue que la surface 40 de la saillie, les rampes 28 et 38 sont séparées par un intervalle D permettant un déplacement angulaire limité du barillet, sans déplacement axial, à partir de la position déverrouillée représentée sur les figures 1, 3 et 4.The internal diameter of the endpiece 26 is slightly greater than the external diameter of a cylindrical part 44 of the fixed body 1 which carries the projection 36, and it surrounds this part 44, as shown in FIG. 1, when the push-button 6 is pushed back outside the wall 2 by the spring 9. The cylinder portion 36 of the body 1 is then practically fitted into the notch of the nozzle 26, the edge 42 abuts against the corresponding face 34 of this nozzle. However, the transverse surface 32 of the end piece being longer than the surface 40 of the projection, the ramps 28 and 38 are separated by an interval D allowing a limited angular displacement of the barrel, without axial displacement, from the unlocked position shown in Figures 1, 3 and 4.

Dans cette position déverrouillée la palette 22 est en regard de l'organe 24 d'ouverture de la serrure et une pression sur le bouton-poussoir 6 déplace axialement la palette et cet organe. Par contre une rotation du barillet 18, sous l'action de sa clé de commande, entraîne le déplacement angulaire de l'embout 26 et de la palette 22, dont il est solidaire, de la distance D et écarte cette dernière de l'organe 24 pendant que la rampe 28 est amenée au contact de la rampe 38. Ensuite les rampes 28 et 38 glissent l'une sur l'autre, au fur et à mesure de la rotation du barillet, ce qui oblige l'embout 26 à reculer progressivement, vers la gauche en regardant les dessins, et à s'éloigner de la paroi 2 de support du corps 1 en entraînant le bouton-poussoir 6 contre l'action du ressort de rappel 9. Lorsque le barillet a effectué environ un demi-tour, l'extrémité de la rampe 28 constituée par le bord extrême 30, atteint la surface transversale 40 de la portion de cylindre 36 et s'applique contre elle, comme le montre la figure 2. L'embout 26 et la saillie 36 sont ainsi en butée l'un contre l'autre bout à bout, tandis que le bouton-poussoir 6 est maintenu entièrement enfoncé à l'intérieur du corps 1. La palette 22 a, bien entendu, effectué en même temps que Le barillet 18 un mouvement angulaire d'environ 180°.Elle est donc dégagée de façon certaine de l'organe d'ouverture de la serrure 24 et placée dans une position verrouillée où elle ne peut avoir aucune action sur la serrure. L'utilisateur est informé de ce verrouillage par la position enfoncée du bouton-poussoir 6.In this unlocked position the pallet 22 is opposite the member 24 for opening the lock and a pressure on the push button 6 axially displaces the pallet and this member. Against by a rotation of the barrel 18, under the action of its control key, causes the angular displacement of the endpiece 26 and the pallet 22, of which it is integral, with the distance D and separates the latter from the member 24 while the ramp 28 is brought into contact with the ramp 38. Then the ramps 28 and 38 slide one over the other, as the barrel rotates, which forces the end piece 26 to move back gradually, to the left while looking at the drawings, and to move away from the wall 2 for supporting the body 1 by driving the push button 6 against the action of the return spring 9. When the barrel has performed approximately one-half turn, the end of the ramp 28 formed by the end edge 30, reaches the transverse surface 40 of the cylinder portion 36 and is applied against it, as shown in FIG. 2. The end piece 26 and the projection 36 are thus in abutment against each other end to end, while the push button 6 is kept fully depressed at the i inside the body 1. The pallet 22 has, of course, carried out at the same time as the barrel 18 an angular movement of approximately 180 °. It is therefore released with certainty from the opening member of the lock 24 and placed in a locked position where it cannot have any action on the lock. The user is informed of this locking by the depressed position of the push button 6.

Le déverrouillage s'obtient par un mouvement inverse du barillet 18 commandé par sa clé. Tout en ramenant la palette 22 vers l'organe d'ouverture 24, la rotation de l'embout 26 dégage le bord extérieur 30 de la surface d'appui 40, place les rampes 28 et 38 en regard, puis les fait glisser l'une contre l'autre pour replacer à nouveau la portion de cylindre 36 dans l'échancrure de l'embout. Au fur et à mesure de la rotation du barillet, le ressort 9 repousse le bouton-poussoir 6 vers l'extérieur et tire l'embout 26 vers la paroi 2.Unlocking is obtained by a reverse movement of the barrel 18 controlled by its key. While bringing the pallet 22 towards the opening member 24, the rotation of the endpiece 26 releases the outer edge 30 of the support surface 40, places the ramps 28 and 38 opposite, then slides them one against the other to replace the cylinder portion 36 again in the notch of the endpiece. As the barrel rotates, the spring 9 pushes the push button 6 outwards and pulls the end piece 26 towards the wall 2.

Etant donné la forme de la saillie 36, dont le contour est complémentaire de celui de la portion échancrée de la paroi de l'embout 26, ces deux organes peuvent facilement avoir le même diamètre extérieur et, par suite, n'occuper qu'un encombrement réduit, qu'ils soient bout à bout ou emboîtés l'un dans l'autre. Bien entendu la portion de cylindre 36 peut être d'une seule pièce avec le corps fixe 1 et constituer une partie de ce corps, le diamètre extérieur de la portion de cylindre 36 et de l'embout 26 étant le même que celui de la partie principale ou portion de centrage du corps 1 dans l'ouverture 5.Given the shape of the projection 36, the contour of which is complementary to that of the indented portion of the wall of the endpiece 26, these two members can easily have the same outside diameter and, consequently, occupy only one reduced overall dimensions, whether they are end to end or nested one inside the other. Of course the cylinder portion 36 may be in one piece with the fixed body 1 and constitute a part of this body, the outside diameter of the cylinder portion 36 and of the end piece 26 being the same as that of the part main or centering portion of the body 1 in the opening 5.

En variante, la portion de cylindre 36 peut être rapportée sur le corps fixe 1 qui, dans ce cas, comporte, comme le montre plus particulièrement la figure 3, une partie de plus faible épaisseur 44 sur laquelle est fixée la portion de cylindre 36.As a variant, the cylinder portion 36 can be attached to the fixed body 1 which, in this case, comprises, as shown more particularly in FIG. 3, a part of thinner thickness 44 on which the cylinder portion 36 is fixed.

Quel que soit le mode de réalisation, l'encombrement transversal de l'ensemble du dispositif de commande est limité à celui de la partie de centrage du corps fixe 1, de sorte que le dispositif peut facilement être monté dans l'ouverture 5 de la paroi en étant engagé, après montage de la palette sur le barillet, dans cette ouverture puis fixé en place.Whatever the embodiment, the transverse size of the whole of the control device is limited to that of the centering part of the fixed body 1, so that the device can easily be mounted in the opening 5 of the wall by being engaged, after mounting the pallet on the barrel, in this opening and then fixed in place.

Le guidage des organes mobiles se faisant le long des rampes hélicoïdales 2.8 et 38, le risque d'usure est limité et la manoeuvre peut être souple et sans frottement important. Par contre, l'arrivée dans la position déverrouillée, c'est-à-dire dans la position de commande de la serrure, est obtenue avec une grande précision par la venue en butée des faces longitudinales 34 et 42 de l'embout et de la portion de cylindre, et l'utilisateur est informé de l'état du dispositif de commande par la position du poussoir. Le dispositif de commande est donc extrêmement précis et fiable, bien que peu encombrant, et facile à réaliser.The guidance of the movable members being done along the helical ramps 2.8 and 38, the risk of wear is limited and the operation can be flexible and without significant friction. By cons, the arrival in the unlocked position, that is to say in the control position of the lock, is obtained with great precision by the abutment of the longitudinal faces 34 and 42 of the nozzle and the cylinder portion, and the user is informed of the state of the control device by the position of the pusher. The control device is therefore extremely precise and reliable, although compact, and easy to produce.
