Description

La présente invention a pour objet un émetteur pour dispositif de commande à distance d'un organe de verrouillage d'au moins une serrure et vise plus particulièrement les émetteurs utilisés pour la commande du verrouillage ou du déverrouillage des serrures de véhicules automobiles.The present invention relates to a transmitter for a remote control device for a locking member of at least one lock and relates more particularly to the transmitters used for controlling the locking or unlocking of motor vehicle locks.

Les dispositifs de commande à distance actuellement utilisés dans l'automobile, tels que ceux décrits dans le brevet d'invention français n° 78/07 726 publié sous le n° 2 420 008 comportent un émetteur d'ondes infrarouges comprenant un boîtier dans lequel sont montés notamment une source d'alimentation en courant continu, un dispositif de génération d'un message codé et un dispositif d'émission dudit message dont l'actionnement est commandé par un bouton poussoir.The remote control devices currently used in the automobile, such as those described in the French invention patent No. 78/07 726 published under No. 2,420,008 include an infrared wave transmitter comprising a housing in which are mounted in particular a DC power source, a device for generating a coded message and a device for transmitting said message, the actuation of which is controlled by a push button.

Dans les dispositifs de ce type actuellement commercialisés et qui équipent notamment les véhicules automobiles produits par la demanderesse de la présente demande, le bouton poussoir est constitué par une portion déformable du corps du boîtier que l'on dé- forme en la pressant afin de provoquer la fermeture d'un contact électrique. Cette solution nécessite une réalisation soignée du corps du boîtier et notamment des épaisseurs de matériaux dans la zone déformable constituant le bouton poussoir.In devices of this type currently on the market and in particular to equip the motor vehicles produced by the assignee of the present application, the pushbutton is constituted by a deformable portion of the housing body which is of E- form by pressing it to cause the closing of an electrical contact. This solution requires careful construction of the housing body and in particular thicknesses of materials in the deformable zone constituting the push button.

Par ailleurs la source d'alimentation en courant continu est constituée par une ou plusieurs piles généralement en forme de disque situées à l'intérieur du boîtier et reliées entre elles par différentes connexions électriques. On constate à l'usage que lors du remplacement de ces piles, l'utilisateur endommage les contacts et les connexions électriques en les déformant ou en les encrassant.Furthermore, the DC power source is constituted by one or more batteries generally in the form of a disc situated inside the case and connected to each other by different electrical connections. It is observed in use that when replacing these batteries, the user damages the contacts and the electrical connections by deforming or fouling them.

L'invention a pour but de proposer un nouveau boîtier émetteur qui remédie aux principaux inconvénients des boîtiers existants et qui viennent d'être énumérés.The object of the invention is to propose a new transmitter box which overcomes the main drawbacks of the existing boxes which have just been listed.

Dans ce but l'invention propose un émetteur caractérisé en ce que le bouton poussoir est constitué par une partie du boîtier de l'émetteur formant couvercle, ledit couvercle étant articulé sur ledit boîtier autour d'un premier axe situé au voisinage d'une première extrémité du couvercle.For this purpose, the invention provides a transmitter characterized in that the push button is constituted by a part of the transmitter housing forming a cover, said cover being articulated on said housing around a first axis located in the vicinity of a first end of the cover.

Ce pivotement du couvercle permet d'agir sur un contact électrique monté dans le corps du boîtier au voisinage de la seconde extrémité du couvercle afin de provoquer l'émission dudit message codé.This pivoting of the cover makes it possible to act on an electrical contact mounted in the body of the box in the vicinity of the second end of the cover in order to cause the emission of said coded message.

Selon une autre caractéristique de l'invention, ladite source d'alimentation en courant continu est montée dans le couvercle. On comprend ainsi qu'elle est susceptible de pivoter avec le couvercle lors de l'ouverture du boîtier notamment en vue de son remplacement. Dans le mode de réalisation représenté, la source de courant est constituée par au moins une pile électrique dont les bornes de raccordement coopèrent avec des contacts électriques correspondants solidaires du corps du boîtier. Grâce à une telle structure, on comprend aisément que l'utilisateur lors du remplacement des piles n'a pas à agir sur les contacts et les connexions électriques mais uniquement à introduire ou à extraire les piles du couvercle auquel elles sont fixées.According to another characteristic of the invention, said DC power source is mounted in the cover. It is thus understood that it is capable of pivoting with the cover when the housing is opened, in particular for its replacement. In the embodiment shown, the current source consists of at least one electric battery, the connection terminals of which cooperate with corresponding electrical contacts secured to the body of the housing. Thanks to such a structure, it is easily understood that the user when replacing the batteries does not have to act on the contacts and the electrical connections but only to insert or remove the batteries from the cover to which they are fixed.

Selon une autre caractéristique de l'invention, le couvercle est articulé sur le boîtier autour d'un second axe d'articulation parallèle audit premier axe d'articulation et situé au voisinage de la seconde extrémité du couvercle, des moyens de verrouillage et de déverrouillage étant prévus pour empêcher tout pivotement du couvercle autour dudit second axe d'articulation lors de l'utilisation normale de l'émetteur et pour permettre un tel pivotement lorsque l'on désire procéder au remplacement de ladite source de courant continu, par exemple constituée par des piles.According to another characteristic of the invention, the cover is articulated on the housing around a second articulation axis parallel to said first articulation axis and located in the vicinity of the second end of the cover, locking and unlocking means being provided to prevent any pivoting of the cover around said second articulation axis during normal use of the transmitter and to allow such pivoting when it is desired to replace said direct current source, for example constituted by batteries.

L'émetteur représenté aux figures comprend un boîtier 10 de forme générale parallélépipédique rectangle qui est constitué essentiellement de trois éléments, un corps 12, un couvercle l4 et un capuchon 16. Le corps 12 et le couvercle 14 sont réalisés dans un matériau thermoplastique, le capuchon 16 étant réalisé en polycarbonate transparent. L'émetteur 10 contient essentiellement une source d'alimentation en courant continu 18, un dispositif de génération d'un message codé 20 schématisé aux figures qui comprend essentiellement des composants électroniques et un dispositif d'émission du message codé comportant essentiellement une diode émettrice d'ondes infrarouges 22 disposée à l'intérieur du boîtier 10 et qui est susceptible d'émettre au travers du capuchon en polycarbonate 16 des ondes dont la réception est prévue par un dispositif récepteur monté à l'intérieur du véhicule automobile dont on désire provoquer l'ouverture d'au moins une serrure. Le boîtier 10 contient également un contact électrique 24 constitué par une lame métallique déformable et élastique 26 susceptible d'être amenée en contact avec un plot 28, un dispositif témoin du bon fonctionnement du dispositif émetteur constitué par une diode électroluminescente 32 dont on peut percevoir l'émission lumineuse au travers d'un orifice 34 formé en vis-à-vis dans le corps du boîtier 12. En complément, l'émetteur représenté aux figures constitue un porte-clefs à clef escamotable 36 montée dans un barillet 38 lui-même monté dans le corps 12 de l'émetteur 10 ; cette structure de porte-clefs a été décrite en détails dans la demande de brevet d'invention n° 82/03 910 déposée le 9 mars 1982 au nom de la demanderesse de la présente demande et au texte de laquelle on pourra se reporter pour obtenir toutes les précisions quant à la description détaillée de cette structure particulière.The transmitter shown in the figures comprises a box 10 of generally rectangular parallelepiped shape which consists essentially of three elements, a body 12, a cover 14 and a cap 16. The body 12 and the cover 14 are made of a thermoplastic material, the cap 16 being made of transparent polycarbonate. The transmitter 10 essentially contains a DC power source 18, a device for generating a coded message 20 shown diagrammatically in the figures which essentially comprises electronic components and a device for transmitting the coded message essentially comprising a transmitter diode d infrared waves 22 disposed inside the housing 10 and which is capable of emitting through the cap polycarbonate 16 waves whose reception is provided by a receiving device mounted inside the motor vehicle which it is desired to cause the opening of at least one lock. The housing 10 also contains an electrical contact 24 constituted by a deformable and elastic metal blade 26 capable of being brought into contact with a stud 28, a device indicating the proper functioning of the emitting device constituted by a light-emitting diode 32 of which one can perceive the 'light emission through an orifice 34 formed vis-à-vis in the body of the housing 12. In addition, the transmitter shown in the figures constitutes a key ring with retractable key 36 mounted in a barrel 38 itself mounted in the body 12 of the transmitter 10; this keyring structure has been described in detail in the patent application No. 82/03 910 filed March 9, 1982 in the name of the applicant of the present application and the text of which we can refer to obtain all details regarding the detailed description of this particular structure.

Le contact électrique 24 décrit plus haut doit pouvoir être actionné par l'utilisateur de l'émetteur d'ondes infrarouges 10 qui désire provoquer le verrouillage ou le déverrouillage d'une serrure au moyen d'un bouton poussoir, une action sur ce contact électrique ayant en effet pour conséquence d'alimenter en courant continu le dispositif de génération 20 du message codé ainsi que son dispositif d'émission 22 de même que l'alimentation du témoin de contrôle 32.The electrical contact 24 described above must be able to be actuated by the user of the infrared wave transmitter 10 who wishes to cause the locking or unlocking of a lock by means of a push button, an action on this electrical contact having the consequence of supplying direct current to the device 20 for generating the coded message as well as its transmission device 22 as well as the supply of the control lamp 32.

Conformément à l'invention, le bouton poussoir de commande du contact électrique 24 est constitué par le couvercle rectangulaire 14 proprement dit qui est monté articulé sur le boîtier 12 autour d'un premier axe d'articulation X-X situé au voisinage d'une première extrémité 40, ou extrémité inférieure(en se référant aux figures) du couvercle 14.According to the invention, the push button for controlling the electrical contact 24 is constituted by the rectangular cover 14 proper which is mounted articulated on the housing 12 around a first articulation axis XX located in the vicinity of a first end 40, or lower end (with reference to the figures) of the cover 14.

Dans le mode de réalisation illustré aux figures, l'axe d'articulation géométrique X-X est constitué matériellement par une charnière 42 comportant un charnon mobile 44 venu de matière avec le couvercle 14 et s'étendant sur une grande partie de la largeur de ce dernier, qui est reçu entre deux portions 46 et 48 constituant les charnons fixes de la charnière et venus de matière avec le corps 12 du boîtier 10. La charnière 44 comporte également un gond 50 constitué par une vis dont la partie d'extrémité pénétrant dans le charnon mobile 44 et le charnon fixe 48 est lisse et dont la partie coopérant avec le charnon fixe 46 est filetée au voisinage de la tête 52 de façon à pouvoir être montée vissée dans le corps 12 dudit boîtier. On comprend ainsi que le gond constitué par la vis 50 peut être extrait à l'aide d'un tournevis en agissant sur la tête de vis 52 depuis l'extérieur du boîtier et ce dans un but qui sera décrit plus avant.In the embodiment illustrated in the figures, the geometric articulation axis XX is constituted materially by a hinge 42 comprising a movable knuckle 44 made integrally with the cover 14 and extending over a large part of the width of the latter , which is received between two portions 46 and 48 constituting the fixed knuckles of the hinge and formed integrally with the body 12 of the housing 10. The hinge 44 also comprises a hinge 50 constituted by a screw whose end part penetrating into the movable knuckle 44 and the fixed knuckle 48 is smooth and whose part cooperating with the fixed knuckle 46 is threaded in the vicinity of the head 52 so as to be able to be mounted screwed into the body 12 of said housing. It is thus understood that the hinge formed by the screw 50 can be extracted using a screwdriver by acting on the screw head 52 from outside the housing and this for a purpose which will be described later.

La source d'alimentation en courant continu 18, qui dans le mode de réalisation est constituée par trois piles en forme de tronçons de cylindre 54, 56 et 58 montées en série, est conformément à l'invention montée dans le couvercle 14. En effet, chacune des piles est montée avec jeux dans un réceptacle délimité d'une part par la face supérieur 60 du charnon mobile 44 et d'autre part par un bras supérieur 62 venu de matière avec le couvercle 14 et qui comporte une extrémité recourbée 64 qui s'étend sur la périphérie de la pile de façon à maintenir celle-ci enclipsée dans son logement correspondant. Comme on peut le constater à la figure 1, chaque pile est reçue dans son logement avec un jeu dans la direction de l'axe X-X de façon à s'assurer que les trois piles sont en contact réciproque et qu'ainsi le montage série est réalisé à coup sûr. La connexion électrique de la source d'alimentation 18 constituée par les trois piles est réalisée par deux contacts électriques 66 et 68 fixés au corps 12 du boîtier 10 dont ils sont solidaires en toutes circonstances. Le contact électrique 66 est constitué par une lame métallique recourbée de façon à posséder une certaine élasticité qui permet d'une part d'assurer un bon contact entre le contact 66 proprement dit et la borne de raccordement de la pile 54 en vis-à-vis et d'autre part entre chacune des piles 54, 56 et 58 et ce en coopération avec le contact 68 qui est d'une structure similaire. Le contact électrique 66 est relié au dispositif de codage du message 20 tandis que le contact 68 est le prolongement inférieur du contact électrique 26 qui, comme cela a été décrit plus avant permet de provoquer le fonctionnement de l'émetteur.The DC power source 18, which in the embodiment consists of three batteries in the form of cylinder sections 54, 56 and 58 mounted in series, is in accordance with the invention mounted in the cover 14. Indeed , each of the batteries is mounted with clearance in a receptacle delimited on the one hand by the upper face 60 of the movable knuckle 44 and on the other hand by an upper arm 62 integrally formed with the cover 14 and which has a curved end 64 which extends over the periphery of the stack so as to keep the latter clipped into its corresponding housing. As can be seen in Figure 1, each battery is received in its housing with a clearance in the direction of the axis XX so as to ensure that the three batteries are in reciprocal contact and that thus the series mounting is realized for sure. The electrical connection of the power source 18 constituted by the three batteries is made by two electrical contacts 66 and 68 fixed to the body 12 of the housing 10 of which they are integral in all circumstances. The electrical contact 66 is constituted by a metal blade curved so as to have a certain elasticity which allows on the one hand to ensure good contact between the contact 66 itself and the connection terminal of the battery 54 opposite and on the other hand between each of the batteries 54, 56 and 58 and this in cooperation with the contact 68 which is of a similar structure. The electrical contact 66 is connected to the message coding device 20 while the contact 68 is the lower extension of the electrical contact 26 which, as has been described above, enables the operation of the transmitter.

Conformément à un autre aspect de l'invention, le couvercle 14 est articulé sur le corps 12 du boîtier 10 autour d'un second axe géométrique d'articulation Y-Y parallèle au premier axe d'articulation X-X et situé au voisinage de la seconde extrémité 70 du couvercle 14 c'est-à-dire à son extrémité supérieure(en considérant les figures) opposée à l'extrémité inférieure 40. Cette deuxième articulation du couvercle 14 a pour but de permettre, comme cela sera décrit plus avant, un remplacement aisé des piles constituant la source d'alimentation en courant continu 18.According to another aspect of the invention, the cover 14 is articulated on the body 12 of the housing 10 around a second geometric axis of articulation YY parallel to the first axis of articulation XX and located in the vicinity of the second end 70 of the cover 14, that is to say at its upper end (considering the figures) opposite the lower end 40. This second articulation of the cover 14 is intended to allow, as will be described later, easy replacement batteries constituting the DC power source 18.

Le second axe d'articulation Y-Y est constitué par deux pivots 72 et 74 venus de matière avec le couvercle 14 et qui sont retenus dans deux logements 76, 78 respectivement formés dans le corps 12 du boîtier 10. Les pivots 72 et 74 sont reliés au couvercle 14 proprement dit par deux prolongements en forme de col de cygne 80 et 82. Chacun des deux logements 76 et 78 reçoit un ressort hélicoïdal 84 et 86 respectivement qui est monté comprimé dans le logement correspondant. Chacun des ressorts de compression 84 et 86 prend appui d'une part sur le fond du logement 88, 90 et d'autre part sur le pivot correspondant 72, 74. Les pivots 72 et 74 sont ainsi sollicités élastiquement en appui contre le second fond de chacun desdits logements 92, 94 respectivement. Les ressorts 76 et 78 constituent ainsi les moyens de rappel élastiques sollicitant le couvercle vers sa position de repos dans laquelle il prend appui sur la surface de butée constituée dans le corps 12 du boîtier par les fonds de logement 92 et 94 avec lesquels coopèrent les pivots 72 et 74. Grâce à une telle structure, les pivots peuvent se déplacer perpendiculairement à leur axe propre afin de permettre le pivotement du couvercle autour du premier axe d'articulation X-X lorsque l'on désire faire fonctionner le dispositif émetteur c'est-à-dire lorsque l'on vient presser sur le couvercle 14 pour l'utiliser comme bouton poussoir ; cette action sur le couvercle ayant en effet pour conséquence de provoquer son pivotement autour de l'axe X-X, les pivots 72 et 74 agissant à l'encontre de l'effort élastique exercé par les ressorts de rappel 84 et 86 et se déplaçant dans les logements 76 et 78 en direction des fonds 88 et 90 desdits logements. Lorsque l'utilisateur relâche sa pression sur le couvercle 14, ce dernier revient vers sa position de repos illustrée notamment aux figures 3 et 4 dans laquelle les pivots sont à nouveau en appui sur les seconds fonds 92 et 94 des logements 76 et 78.The second axis of articulation YY consists of two pivots 72 and 74 formed integrally with the cover 14 and which are retained in two housings 76, 78 respectively formed in the body 12 of the housing 10. The pivots 72 and 74 are connected to the cover 14 proper by two swan-neck extensions 80 and 82. Each of the two housings 76 and 78 receives a helical spring 84 and 86 respectively which is mounted compressed in the corresponding housing. Each of the compression springs 84 and 86 bears on the one hand on the bottom of the housing 88, 90 and on the other hand on the corresponding pivot 72, 74. The pivots 72 and 74 are thus resiliently biased in abutment against the second bottom of each of said housings 92, 94 respectively. The springs 76 and 78 thus constitute the elastic return means urging the cover towards its rest position in which it bears on the abutment surface formed in the body 12 of the housing by the housing bottoms 92 and 94 with which the pivots cooperate. 72 and 74. Thanks to such a structure, the pivots can move perpendicular to their own axis in order to allow the pivoting of the cover around the first articulation axis XX when it is desired to operate the transmitter device, that is to say when the cover 14 is pressed to use it as a push button; this action on the cover having the effect of causing it to pivot about the axis XX, the pivots 72 and 74 acting against the elastic force exerted by the return springs 84 and 86 and moving in the housing 76 and 78 in the direction of funds 88 and 90 of said housing. When the user releases his pressure on the cover 14, the latter returns to its rest position illustrated in particular in FIGS. 3 and 4 in which the pivots are again supported on the second bottoms 92 and 94 of the housings 76 and 78.

Conformément à l'invention, la charnière 42 comportant le gond amovible 50 constitue les moyens de verrouillage et de déverrouillage qui sont prévus pour empêcher tout pivotement du couvercle 14 autour du second axe d'articulation Y-Y lors de l'utilisation normale de l'émetteur, mais qui permettent un tel pivotement lorsque l'on désire procéder au remplacement des piles. En effet, il suffit à l'utilisateur de dévisser le gond 50 et de l'extraire du boîtier pour pouvoir ensuite faire pivoter le couvercle 14 autour de l'axe Y-Y comme cela est indiqué par la flèche A de la figure 2 jusqu'à ce que ce couvercle vienne occuper la position représentée en traits mixtes à cette même figure qui est la position d'ouverture maximale du couvercle prévue pour le remplacement des piles. Dans cette position ouverte, l'utilisateur n'a plus qu'à extraire les piles de leur logement correspondant et ce en déformant légèrement et de manière élastique les bras 64 tant pour extraire les piles usagées que pour y introduire de nouvelles piles. Une fois le remplacement des piles effectué, l'utilisateur n'a plus qu'à refermer le couvercle 14 en agissant dans la direction indiquée par la flèche B de la figure 2 ; lors de cette manoeuvre, les piles sont progressivement engagées entre les contacts électrique et élastique 66 et 68 qui viennent assurer une parfaite connexion électrique du circuit sans que l'utilisateur n'ait à aucun moment l'occasion de toucher ces contacts au risque notamment de les déformer. Une fois que le couvercle occupe à nouveau sa position normale de repos, l'utilisateur peut réintroduire le gond 50 dans les charnons 44,46 et 48 puis visser à nouveau la tête 52 de la vis de façon à immobiliser le gond 50 par rapport au boîtier 10. L'émetteur est à nouveau prêt pour son utilisation normale au cours de laquelle le couvercle 14 est seulement libre de pivoter autour du premier axe d'articulation X-X en vue de son utilisation comme bouton poussoir.According to the invention, the hinge 42 comprising the removable hinge 50 constitutes the locking and unlocking means which are provided to prevent any pivoting of the cover 14 around the second axis of articulation YY during normal use of the transmitter. , but which allow such pivoting when it is desired to replace the batteries. Indeed, it suffices for the user to unscrew the hinge 50 and extract it from the housing in order to then be able to pivot the cover 14 around the axis YY as indicated by the arrow A in FIG. 2 until that this cover comes to occupy the position shown in phantom in this same figure which is the maximum opening position of the cover provided for the replacement of the batteries. In this open position, the user only has to extract the batteries from their corresponding housing and this by slightly and resiliently deforming the arms 64 both for removing the used batteries and for inserting new batteries. Once the batteries have been replaced, the user only has to close the cover 14 by acting in the direction indicated by the arrow B in FIG. 2; during this operation, the batteries are progressively engaged between the electrical and elastic contacts 66 and 68 which provide perfect electrical connection to the circuit without the user having at any time the opportunity to touch these contacts at the risk in particular of deforming them. Once the cover once again occupies its normal rest position, the user can reintroduce the hinge 50 into the knuckles 44, 46 and 48 and then screw the head 52 of the screw again so as to immobilize the hinge 50 relative to the housing 10. The transmitter is again ready for normal use during which the cover 14 is only free to pivot around the first hinge axis XX for use as a push button.
