Description

PROGRAMMATEUR ÉLECTROMÉCANIQUE  ELECTROMECHANICAL PROGRAMMER
L'invention concerne un programmateur électromécanique et plus particulièrement un tel programmateur utilisant des segments de programmation en forme de secteurs circulaires, présentant des facilités de programmation améliorées. L'invention concerne également un connecteur électrique programmable comportant un tel programmateur.  The invention relates to an electromechanical programmer and more particularly to such a programmer using programming segments in the form of circular sectors, having improved programming facilities. The invention also relates to a programmable electrical connector comprising such a programmer.
On connaît, par exemple du document FR 2 875 941 un programmateur électromécanique adapté pour commander la circulation et l'interruption d'un courant électrique entre une prise d'entrée et une prise de sortie. un tel programmateur couvre une durée totale de 24 heures et comprend un cadran ou couronne de programmation muni à sa périphérie de 96 segments mobiles entre deux positions (repos et travail) correspondant à des périodes de temps d'un quart d'heure pendant lesquelles la circulation du courant électrique est respectivement permise ou empêchée. Cependant, la manipulation de ces segments est délicate à main nue, d'autant plus que le diamètre extérieur du cadran est réduit, par exemple pour des raisons d'encombrement, et que le nombre de segments est élevé (par exemple 168 segments pour un programmateur hebdomadaire avec une résolution d'une heure par segment).  Document FR 2 875 941 discloses an electromechanical programmer adapted to control the circulation and the interruption of an electric current between an input socket and an output socket. such a programmer covers a total duration of 24 hours and comprises a dial or programming ring provided at its periphery with 96 segments movable between two positions (rest and work) corresponding to periods of time of a quarter of an hour during which the flow of electric current is respectively allowed or prevented. However, the manipulation of these segments is difficult to bare hands, especially as the outer diameter of the dial is reduced, for example for reasons of space, and the number of segments is high (for example 168 segments for weekly programmer with a resolution of one hour per segment).
Le document GB 2 318 213 propose, pour pallier ce problème, d'utiliser un bouton poussoir fixé sur le boîtier du programmateur à la périphérie de la couronne de programmation, en regard des segments de programmation. À chaque appui sur le bouton poussoir, un segment est déplacé de sa position de repos vers sa position de travail. Si cette solution permet d'améliorer la précision de la manipulation des segments, elle présente néanmoins de nombreux inconvénients. En effet, pour changer l'état d'un segment, il convient de l'amener en regard du bouton poussoir en tournant la couronne de programmation ce qui a pour conséquence la perte de l'heure actuelle indiquée par le cadran. De plus, la programmation d'une plage horaire de fonctionnement nécessite généralement l'utilisation des deux mains de l'opérateur, l'une pour faire tourner la couronne et l'autre pour appuyer sur le bouton poussoir devant chaque segment. La présente invention vise un programmateur électromécanique qui ne présente pas ces inconvénients et qui permet notamment la programmation des plages de fonctionnement à une main, sans perte de la référence horaire courante du programmateur. The document GB 2 318 213 proposes, to overcome this problem, to use a push button fixed on the programmer housing at the periphery of the programming ring, opposite the programming segments. Each time the push button is pressed, a segment is moved from its rest position to its working position. Although this solution makes it possible to improve the precision of the manipulation of the segments, it nevertheless has many disadvantages. Indeed, to change the state of a segment, it should be brought next to the push button by turning the programming ring which results in the loss of the current time indicated by the dial. In addition, programming an operating time slot generally requires the use of both hands of the operator, one to rotate the crown and the other to press the push button in front of each segment. The present invention aims at an electromechanical programmer which does not have these drawbacks and which allows in particular the programming of operating ranges with one hand, without loss of the current time reference of the programmer.
Pour ce faire, l'invention concerne un programmateur électromécanique comportant :  To do this, the invention relates to an electromechanical programmer comprising:
- un boîtier, comportant un repère fixe  a housing, having a fixed reference
- une couronne de programmation entraînée en rotation par un moteur électrique solidaire du boîtier et adaptée pour effectuer une rotation complète dans un temps prédéterminé, dit cycle temporel, ladite couronne de programmation comportant un cadran défilant devant le repère fixe et indiquant la position de la couronne de programmation dans le cycle temporel,  - A programming ring driven in rotation by an electric motor secured to the housing and adapted to perform a complete rotation in a predetermined time, said time cycle, said programming ring comprising a dial scrolling in front of the fixed mark and indicating the position of the crown programming in the time cycle,
- une pluralité de segments de programmation, portés par la couronne de programmation, et s 'étendant chacun sur un secteur circulaire correspondant à une fraction du cycle temporel pendant laquelle un contact électrique est ouvert ou fermé, lesdits segments étant mobiles entre deux positions, une première position, dite position de repos, dans laquelle le contact électrique est en position ouverte et une deuxième position, dite position de travail, dans laquelle le contact électrique est en position fermée,  a plurality of programming segments, carried by the programming ring, and each extending over a circular sector corresponding to a fraction of the time cycle during which an electrical contact is open or closed, said segments being movable between two positions; first position, said rest position, in which the electrical contact is in the open position and a second position, said working position, in which the electrical contact is in the closed position,
caractérisé en ce que ledit programmateur comporte une deuxième couronne, dite couronne de sélection, coaxiale à la couronne de programmation, mobile en rotation par rapport à celle-ci dans au moins un sens de rotation et mobile axialement entre au moins une première position dite position neutre et une deuxième position dite position de programmation, ladite couronne de sélection comportant un index indiquant la position de la couronne de sélection par rapport à la couronne de programmation et un ergot, dit ergot de programmation, placé en regard dudit index et agencé pour que lorsque la couronne de sélection est en position de programmation, un segment de programmation en regard de l'ergot de programmation, est en position de travail. Grâce à la couronne de sélection, il n'est plus nécessaire de faire tourner la couronne de programmation (ce qui modifie l'heure affichée sur le programmateur) pour amener le segment que l'on veut programmer sous un doigt de programmation. Il suffit d'amener l'index de la couronne de sélection au droit du segment considéré en se repérant par rapport au cadran de la couronne de programmation, et de déplacer axialement la couronne de sélection entre sa position neutre et sa position de programmation. L'ergot de programmation, sous l'effet du déplacement axial de la couronne de sélection, déplace alors le segment considéré de sa position de repos vers sa position de travail. Avantageusement, lorsque l'on veut programmer une plage de segments contigus, il suffit d'amener l'index de la couronne de sélection au droit du premier segment de la plage, de déplacer la couronne de sélection vers la position de programmation, puis de tourner la couronne de sélection, tout en la maintenant dans la position de programmation, jusqu'au dernier segment de la plage. En choisissant judicieusement l'angle des flancs de l'ergot de programmation, il est possible de déplacer de proche en proche les segments de programmation sans avoir besoin de changer la position de la couronne de sélection. characterized in that said programmer comprises a second ring, said ring gear, coaxial with the programming ring, movable in rotation relative thereto in at least one direction of rotation and axially movable between at least a first position called position neutral and a second position said programming position, said selection ring comprising an index indicating the position of the selection ring relative to the programming ring and a lug, said programming pin, placed opposite said index and arranged so that when the selection ring is in the programming position, a programming segment opposite the programming pin is in the working position. Thanks to the selection crown, it is no longer necessary to turn the programming crown (which changes the time displayed on the programmer) to bring the segment that you want to program under a programming finger. It is sufficient to bring the index of the selection ring to the right of the segment in question by locating with respect to the dial of the programming ring, and to move axially the selection ring between its neutral position and its programming position. The programming pin, under the effect of the axial displacement of the selection ring, then moves the segment considered from its rest position to its working position. Advantageously, when programming a range of contiguous segments, it is sufficient to bring the index of the selection ring to the right of the first segment of the range, to move the selection ring to the programming position, then to turn the selection crown, while holding it in the programming position, until the last segment of the range. By judiciously choosing the angle of the flanks of the programming lug, it is possible to move the programming segments step by step without having to change the position of the selection crown.
Avantageusement et selon l'invention, la position de programmation de la couronne de sélection est une position transitoire rappelée vers la position neutre par un premier ressort. Grâce à ce premier ressort de rappel, la couronne de sélection est automatiquement rappelée de sa position de programmation à sa position neutre dès que l'opérateur relâche sa pression (ou sa traction) sur la couronne de sélection.  Advantageously and according to the invention, the programming position of the selection ring is a transient position returned to the neutral position by a first spring. With this first return spring, the selection ring is automatically recalled from its programming position to its neutral position as soon as the operator releases its pressure (or traction) on the selection ring.
Avantageusement et selon l'invention, la couronne de sélection comporte en outre une position, dite position de remise à zéro, à l'opposé de sa position de programmation par rapport à la position neutre. Afin de pouvoir ramener les segments de programmation de leur position de travail vers leur position de repos, la couronne de sélection peut être déplacée à l'opposé de sa position de programmation. Ainsi, si la position de programmation est obtenue en appuyant sur la couronne de sélection pour déplacer les segments de programmation entre une position « haute » de repos et une position « basse » de travail, la position de remise à zéro est obtenue en tirant axialement la couronne de sélection. Dans une première variante, la couronne de sélection peut comporter un rebord passant sous tous les segments de programmation de telle sorte que le déplacement de la couronne de sélection vers sa position de remise à zéro permette de faire remonter tous les segments simultanément en position de repos. Advantageously and according to the invention, the selection ring further comprises a position, called reset position, opposite its programming position relative to the neutral position. In order to be able to return the programming segments from their working position to their rest position, the selection crown can be moved away from its programming position. So, if the programming position is obtained by pressing the selection crown to move the programming segments between a "high" rest position and a "low" work position, the reset position is obtained by axially pulling the selection crown. In a first variant, the selection ring may comprise a flange passing under all the programming segments so that the displacement of the selection ring towards its reset position makes it possible to raise all the segments simultaneously in the rest position. .
Avantageusement et selon l'invention, la couronne de sélection comporte un deuxième ergot, dit ergot de remise à zéro, adapté pour déplacer chaque segment de sa position de travail à sa position de repos lorsque la couronne de sélection est en position de remise à zéro. Dans cette variante préférentielle, le retour d'un segment de programmation vers sa position de repos s'effectue sélectivement grâce à l'action de l'ergot de remise à zéro qui permet d'agir sur un segment unique ou sur une plage de segments par rotation de la couronne de sélection lorsqu'elle est en position de remise à zéro.  Advantageously and according to the invention, the selection ring comprises a second lug, called reset lug, adapted to move each segment from its working position to its rest position when the selection ring is in the reset position. . In this preferred embodiment, the return of a programming segment to its rest position is done selectively by virtue of the action of the reset pin which makes it possible to act on a single segment or on a range of segments. by rotating the selection ring when it is in the reset position.
Avantageusement et selon l'invention, la position de remise à zéro de la couronne de sélection est une position transitoire rappelée vers la position neutre par un deuxième ressort. De la même manière que pour la position de programmation, la couronne de sélection peut être ainsi ramenée vers sa position neutre lorsque l'effort de déplacement axial exercé par l'opérateur s'annule.  Advantageously and according to the invention, the reset position of the selection ring is a transient position returned to the neutral position by a second spring. In the same way as for the programming position, the selection ring can thus be brought back to its neutral position when the axial displacement force exerted by the operator vanishes.
Avantageusement et selon l'invention, la couronne de sélection comporte des moyens de solidarisation adaptés pour coopérer avec la couronne de programmation de manière à permettre une rotation libre de la couronne de sélection par rapport à la couronne de programmation dans un premier sens de rotation et à entraîner en rotation la couronne de programmation dans l'autre sens de rotation. Grâce à ces moyens de solidarisation, la couronne de sélection peut se déplacer librement par rapport à la couronne de programmation dans un premier sens de rotation, dit sens de programmation, et entraîner en rotation la couronne de programmation dans un autre sens de rotation, dit sens de réglage horaire. Ainsi dans le sens de réglage horaire, il est possible de régler l'heure du programmateur en déplaçant la couronne de programmation de telle sorte que l'heure marquée sur le cadran de la couronne de programmation et correspondant à l'heure actuelle soit placée en regard du repère fixe du boîtier. Advantageously and according to the invention, the selection ring comprises securing means adapted to cooperate with the programming ring so as to allow free rotation of the selection ring with respect to the programming ring in a first direction of rotation and rotating the programming ring in the other direction of rotation. Thanks to these securing means, the selection ring can move freely relative to the programming ring in a first direction of rotation, said programming direction, and rotate the programming ring in another direction of rotation, said clock setting direction. Thus in the time setting direction, it is possible to set the time of the programmer by moving the programming crown so that the time marked on the dial of the programming crown and corresponding to the present time is placed opposite the fixed reference of the housing.
Avantageusement et selon l'invention, les moyens de solidarisation comportent au moins un cliquet élastique adapté pour coopérer avec une roue d'engrenage intérieur de la couronne de programmation. Une des solutions pour la réalisation de ces moyens de solidarisation consiste à prévoir un cliquet élastique ménagé sur une paroi interne de la couronne de sélection et comportant au moins une dent de profil asymétrique s'engageant dans la roue d'engrenage intérieur de la couronne de programmation prévue pour l'entraînement de celle-ci par le moteur électrique .  Advantageously and according to the invention, the securing means comprise at least one resilient pawl adapted to cooperate with a gear wheel inside the programming ring. One of the solutions for the realization of these securing means consists in providing an elastic pawl formed on an inner wall of the selection ring and comprising at least one asymmetrical profile tooth engaging in the inner gear wheel of the ring gear. programmed programming for the drive of it by the electric motor.
Avantageusement et selon l'invention, la couronne de sélection comporte au moins une bague transparente qui recouvre la couronne de programmation et les segments de programmation pour laisser apparaître au moins partiellement le cadran de la couronne de programmation et les segments de programmation. Grâce à cette bague transparente, la couronne de programmation est à l'abri d'un accès direct, ce qui permet d'éviter l'effacement du cadran horaire et de modifier la position des segments de programmation, voire même leur perte éventuelle.  Advantageously and according to the invention, the selection ring comprises at least one transparent ring which covers the programming ring and the programming segments to reveal at least partially the dial of the programming ring and the programming segments. Thanks to this transparent ring, the programming crown is protected from direct access, which makes it possible to avoid the erasure of the time dial and to modify the position of the programming segments, or even their possible loss.
Avantageusement et selon l'invention, la couronne de programmation comporte au moins un indicateur d'état pour indiquer visuellement la position repos ou travail des segments de programmation. Ainsi, par exemple, un liseré de couleur porté par la couronne de programmation peut être découvert et rendu visible par le déplacement du segment de programmation de sa position repos à sa position travail.  Advantageously and according to the invention, the programming ring comprises at least one status indicator for visually indicating the rest or working position of the programming segments. Thus, for example, a colored border carried by the programming ring can be discovered and made visible by the displacement of the programming segment from its rest position to its working position.
Avantageusement et selon l'invention, l'indicateur d'état comporte un éclairage à diodes électroluminescentes adapté pour illuminer au moins une partie de la couronne de programmation en regard des plages de segments en position travail. Dans une version plus élaborée, un anneau lumineux à base de diodes électroluminescentes et une couronne de programmation au moins en partie translucide en regard de la zone découverte par les segments lorsqu'ils sont en position travail permettent de rendre visible les plages de programmation. Advantageously and according to the invention, the state indicator comprises a light-emitting diode illumination adapted to illuminate at least a portion of the programming ring facing segments ranges in working position. In a more elaborate version, a light ring based on light-emitting diodes and a programming ring at least in Translucent part facing the zone discovered by the segments when they are in working position make visible the programming ranges.
Avantageusement et selon l'invention, le programmateur comporte une prise centrale entourée par les couronnes de programmation et de sélection. D'autres versions, par exemple pour installation dans un tableau d'appareillage électrique (régulateur de température à plages horaires programmables, etc.) peuvent ne pas comporter de prise électrique et directement commuter d'autres courants / tensions que celles de l'alimentation secteur.  Advantageously and according to the invention, the programmer comprises a central socket surrounded by the programming and selection crowns. Other versions, for example for installation in a switchgear panel (temperature controller with programmable time zones, etc.) may not have an electrical outlet and directly switch other currents / voltages than those of the power supply. sector.
L'invention concerne également un programmateur électromécanique caractérisé en combinaison par tout ou partie des caractéristiques mentionnées ci-dessus ou ci-après.  The invention also relates to an electromechanical programmer characterized in combination by all or some of the characteristics mentioned above or below.
D'autres buts, caractéristiques et avantages de l'invention apparaîtront au vu de la description qui va suivre et des dessins annexés dans lesquels :  Other objects, features and advantages of the invention will become apparent from the following description and the appended drawings in which:
- la figure 1 représente une vue en perspective d'un programmateur selon l'invention,  FIG. 1 represents a perspective view of a programmer according to the invention,
- la figure 2 représente une demi-coupe radiale d'un programmateur selon l'invention par un plan passant par l'index de la couronne de sélection,  FIG. 2 represents a radial half-section of a programmer according to the invention by a plane passing through the index of the selection crown,
- la figure 3 est une vue en perspective éclatée des constituants d'un programmateur selon l'invention.  - Figure 3 is an exploded perspective view of the components of a programmer according to the invention.
Le programmateur 1 illustré sur la figure 1 comporte un boîtier 2 constitué d'une cuve 2a comportant sur sa face inférieure (non visible) une prise mâle comportant deux broches saillantes adaptées pour être insérées dans les douilles d'une prise femelle et, le cas échéant, une douille permettant d'accueillir une broche de mise à la terre portée par la prise femelle. La cuve 2a est fermée en partie supérieure par un couvercle 2b comportant une ouverture circulaire laissant apparaître les couronnes de sélection 9 et de programmation 4. Ces couronnes sont centrées par une partie 2c du boîtier formant le corps d'une prise femelle 20. Le rebord de la partie 2c du boîtier comporte un repère 3 fixe par rapport au boîtier. La couronne de sélection 9 comporte deux parties, une bague transparente 9a au travers de laquelle on peut voir la couronne de programmation 4 et une bague extérieure 9b permettant d'assurer la préhension de la couronne de sélection 9. La couronne de sélection 9 porte également un index 10 permettant de repérer la position de la couronne de sélection par rapport à la couronne de programmation 4. The programmer 1 illustrated in Figure 1 comprises a housing 2 consisting of a tank 2a having on its underside (not visible) a plug having two protruding pins adapted to be inserted into the sockets of a socket and, if the case a socket for receiving a grounding pin carried by the socket. The tank 2a is closed at the top by a cover 2b having a circular opening showing the selection crowns 9 and programming 4. These rings are centered by a portion 2c of the housing forming the body of a socket 20. The rim part 2c of the housing has a fixed mark 3 relative to the housing. The selection ring 9 comprises two parts, a transparent ring 9a through which we can see the programming ring 4 and an outer ring 9b to ensure the gripping of the selection ring 9. The selection ring 9 also carries an index 10 for locating the position of the selection ring relative to the programming ring 4.
La couronne de programmation 4 porte un cadran 6 sur lequel est dessinée une échelle horaire couvrant une période de 24 heures dans l'exemple de la figure 1. Bien entendu, d'autres échelles peuvent être portées sur le cadran 6 en fonction du cycle temporel du programmateur. Sur le dessin de la figure 1, un arraché de la couronne de sélection 9 placé entre les graduations horaires de 23 heures à 2 heures permet d'apercevoir les segments de programmation 7 portés par la couronne de programmation 4. Dans l'exemple représenté, chaque segment de programmation 7 couvre une période de un quart d'heure.  The programming crown 4 carries a dial 6 on which is drawn a time scale covering a period of 24 hours in the example of FIG. 1. Of course, other scales can be worn on the dial 6 as a function of the time cycle. of the programmer. In the drawing of FIG. 1, a snatch of the selection ring 9 placed between the hourly graduations from 23 o'clock to 2 o'clock makes it possible to see the programming segments 7 carried by the programming ring 4. In the example shown, each programming segment 7 covers a period of fifteen minutes.
Le boîtier 2 porte également sur le couvercle 2b, à l'extérieur des couronnes de sélection 9 et de programmation 4, un interrupteur, dit interrupteur de mode 21, permettant de sélectionner le mode de fonctionnement du programmateur, par exemple entre un mode de fonctionnement programmé et un mode de fonctionnement en alimentation continue. L'interrupteur de mode peut également être fixé sur une des parois de la cuve 2a.  The housing 2 also carries on the cover 2b, outside the selection rings 9 and programming 4, a switch, said mode switch 21, for selecting the operating mode of the programmer, for example between a mode of operation programmed and a mode of operation in continuous supply. The mode switch can also be attached to one of the walls of the tank 2a.
On se réfère maintenant aux figures 2 et 3 pour décrire de manière plus détaillée la structure et le fonctionnement du programmateur de l'invention.  Reference is now made to FIGS. 2 and 3 to describe in more detail the structure and operation of the programmer of the invention.
La cuve 2a du boîtier 2 contient, outre les connexions électriques de la prise mâle située au-dessous de la cuve et les connexions électriques avec la prise 20 accessibles par le dessus du programmateur 1, un moteur électrique 5 dont l'arbre de sortie comporte un pignon 5a coopérant avec une roue d'engrenage intérieur 17 faisant partie de la couronne de programmation 4. La cuve 2a contient également un contact 8 électrique comportant un palpeur 8a adapté pour fermer le contact 8 électrique lorsque le palpeur rencontre une partie saillante d'un segment de programmation 7 placé en position de travail. Le contact 8 électrique comporte également l'interrupteur de mode 21 qui permet de court- circuiter le contact 8 lorsqu'il est en mode de fonctionnement en alimentation continue. Le levier de manœuvre de l'interrupteur de mode 21 traverse le couvercle 2b du boîtier. The tank 2a of the housing 2 contains, in addition to the electrical connections of the plug located below the tank and the electrical connections with the jack 20 accessible from above the programmer 1, an electric motor 5 whose output shaft comprises a pinion 5a cooperating with an internal gear wheel 17 forming part of the programming ring 4. The tank 2a also contains an electrical contact 8 comprising a feeler 8a adapted to close the electrical contact 8 when the probe encounters a protruding part a programming segment 7 placed in working position. The electrical contact 8 also includes the mode switch 21 which makes it possible to short-circuit the contact 8 when it is in continuous supply operation mode. The operating lever of the mode switch 21 passes through the cover 2b of the housing.
La couronne de programmation 4 comprend un flanc interne cylindrique comportant la roue d'engrenage interne 17 permettant de l'entraîner en rotation par le pignon 5 a du moteur 5. La couronne de programmation 4 comprend également une aile cylindrique externe comportant deux rainures périphériques extérieures. Les segments de programmation 7 enfourchent élastiquement cette aile et comportent une dent coopérant avec l'une des deux rainures en fonction de la position de travail 7T ou de repos 7R de chaque segment.  The programming ring 4 comprises a cylindrical internal flank comprising the internal gear wheel 17 enabling it to be rotated by the pinion 5a of the motor 5. The programming ring 4 also comprises an outer cylindrical wing comprising two outer peripheral grooves . The programming segments 7 elastically load this wing and have a tooth cooperating with one of the two grooves according to the working position 7T or rest 7R of each segment.
Le dessus de la couronne de programmation 4 porte le cadran 6. Avantageusement, la couronne de programmation 4 peut être réalisée en un matériau translucide permettant de diffuser dans son épaisseur la lumière générée par un éclairage 19 à diodes électroluminescentes noyées dans un renfoncement de la couronne de programmation. Dans ce cas, le cadran 6 est par exemple peint ou sérigraphié en noir et les chiffres et graduations laissés non recouverts pour permettre la diffusion de la lumière pour former un cadran lumineux. Dans ce mode de réalisation, une bande cylindrique non recouverte est laissée sur la face externe de l'aile portant les segments 7, au-dessus des rainures, de telle sorte que lorsqu'un segment est en position travail, il laisse transparaître une indication lumineuse par cette bande et lorsqu'il est en position de repos, il masque cette bande lumineuse sur le secteur circulaire qu'il occupe.  The top of the programming ring 4 carries the dial 6. Advantageously, the programming ring 4 can be made of a translucent material for diffusing in its thickness the light generated by a lighting 19 with light emitting diodes embedded in a recess of the crown programming. In this case, the dial 6 is for example painted or serigraphed in black and the numbers and graduations left uncovered to allow the diffusion of light to form a luminous dial. In this embodiment, an uncovered cylindrical strip is left on the outer face of the wing carrying the segments 7, above the grooves, so that when a segment is in the working position, it allows to show an indication. illuminated by this band and when in the rest position, it masks this luminous band on the circular sector which it occupies.
Selon un autre mode de réalisation d'un indicateur visuel de la position des segments de programmation, la couronne de programmation ne comporte pas d'éclairage et une bande de peinture contrastée, par exemple luminescente, est placée sur la face externe de l'aile portant les segments de telle sorte qu'elle soit découverte lorsque le segment 7 est en position de travail et masquée par le segment lorsqu'il est en position de repos. La couronne de programmation 4 est coiffée par la couronne de sélection 9, et en particulier par la bague transparente 9a de la couronne de sélection. La bague transparente 9a est cerclée par la bague extérieure 9b et les deux bagues sont fixées entre elles par exemple par collage pour former la couronne de sélection 9. Dans l'exemple représenté à la figure 2, la couronne de sélection est mobile axialement entre trois positions, comme représenté par la double flèche attachée à la bague extérieure 9b, une position dite position neutre N et repérée par la lettre N au centre, une position de programmation P repérée par la lettre P vers la gauche du dessin et une position de remise à zéro Z repérée par la lettre Z vers la droite du dessin. According to another embodiment of a visual indicator of the position of the programming segments, the programming crown has no illumination and a contrasting paint strip, for example luminescent, is placed on the outer face of the wing carrying the segments so that it is discovered when the segment 7 is in the working position and masked by the segment when in the rest position. The programming ring 4 is capped by the selection ring 9, and in particular by the transparent ring 9a of the selection ring. The transparent ring 9a is surrounded by the outer ring 9b and the two rings are fixed together for example by gluing to form the selection ring 9. In the example shown in Figure 2, the selection ring is axially movable between three positions, as represented by the double arrow attached to the outer ring 9b, a position called neutral position N and marked by the letter N in the center, a programming position P marked by the letter P to the left of the drawing and a position of delivery at zero Z marked by the letter Z to the right of the drawing.
La couronne de sélection 9 comporte, en regard de l'index 10, un ergot, dit ergot de programmation 11. Cet ergot de programmation 11, d'une largeur légèrement inférieure à celle d'un segment de programmation 7, vient en appui sur le segment de programmation en position de repos et le déplace vers sa position de travail jusqu'à ce que la dent du segment vienne s'engager dans la deuxième rainure de la couronne de programmation 4, en position de travail 7T. Il est ainsi possible, par un simple appui sur la couronne de sélection 9, de programmer la mise en service du contact 8 sur la fraction du cycle temporel correspondant à un unique segment. En outre, les flancs de l'ergot de programmation 11 sont d'une forme ou d'une pente adaptée pour qu'une rotation de la couronne de sélection, en position de programmation, permette de déplacer les segments de programmation 7 en position de travail sans qu'il soit besoin de revenir à la position neutre de la couronne de sélection.  The selection ring 9 comprises, facing the index 10, a lug, said programming lug 11. This programming lug 11, a width slightly smaller than that of a programming segment 7, bears on the programming segment in the rest position and moves it to its working position until the tooth of the segment comes to engage in the second groove of the programming ring 4, in the working position 7T. It is thus possible, by a simple press on the selection ring 9, to program the commissioning of the contact 8 on the fraction of the time cycle corresponding to a single segment. In addition, the flanks of the programming lug 11 are of a shape or of a slope adapted so that a rotation of the selection ring, in the programming position, makes it possible to move the programming segments 7 in the position of work without the need to return to the neutral position of the selection crown.
La couronne de sélection 9 comporte également, toujours en regard de l'index 10, un deuxième ergot, dit ergot de remise à zéro 13, porté par exemple par un rebord inférieur de la bague externe 9b. De manière analogue à l'ergot de programmation 11, l'ergot de remise à zéro permet de déplacer sélectivement un ou plusieurs segments de programmation 7 de leur position de travail 7T à leur position de repos 7R lorsque la couronne de sélection 9 est déplacée vers sa position de remise à zéro Z, par une traction des doigts d'un utilisateur sur la bague externe 9b. The selection ring 9 also comprises, always opposite the index 10, a second lug, said reset pin 13, carried for example by a lower edge of the outer ring 9b. In a similar manner to the programming pin 11, the reset pin makes it possible to selectively move one or more programming segments 7 from their working position 7T to their rest position 7R when the selection ring 9 is moved to its Z reset position by pulling a user's fingers on the outer ring 9b.
Avantageusement, les deux positions extrêmes de la couronne de sélection 9, à savoir la position de programmation P et la position de remise à zéro Z sont des positions transitoires, c'est-à-dire que la couronne de sélection 9 doit être maintenue dans cette position. En effet, dès que la couronne de sélection est relâchée, elle est ramenée dans sa position neutre N sous l'effet d'un ressort de rappel. Par exemple, lorsque la couronne de sélection 9 est déplacée vers la position de programmation P, le bord inférieur de la bague externe 9b déforme les languettes élastiques d'un ressort de rappel 12 placé entre le couvercle 2b et la bague extérieure 9b. Dès que l'effort de maintien en position de programmation de la couronne de sélection est relâché, le ressort de rappel 12 ramène la couronne de sélection en position neutre.  Advantageously, the two extreme positions of the selection ring 9, namely the programming position P and the reset position Z are transient positions, that is to say that the selection ring 9 must be maintained in this position. Indeed, as soon as the selection ring is released, it is returned to its neutral position N under the effect of a return spring. For example, when the selection ring 9 is moved to the programming position P, the lower edge of the outer ring 9b deforms the resilient tongues of a return spring 12 placed between the cover 2b and the outer ring 9b. As soon as the effort of maintaining the programming position of the selection crown is released, the return spring 12 returns the selection crown to the neutral position.
De même, un ressort de rappel 14, placé entre un épaulement intérieur de la bague transparente 9a de la couronne de sélection 9 et le fond de la partie 2c du boîtier 2 exerce un effort de rappel de la couronne de sélection 9 vers sa position neutre lorsque la couronne de sélection est déplacée vers sa position de remise à zéro. Grâce à ces ressorts de rappel 12 et 14, la couronne de sélection 9 est toujours, en l'absence d'effort extérieur, dans une position stable et neutre ce qui évite une programmation ou une déprogrammation intempestive de segments lors d'une rotation volontaire ou non de la couronne de sélection.  Similarly, a return spring 14 placed between an inner shoulder of the transparent ring 9a of the selection ring 9 and the bottom of the portion 2c of the housing 2 exerts a return force of the selection ring 9 towards its neutral position. when the selection ring is moved to its reset position. With these return springs 12 and 14, the selection ring 9 is always, in the absence of external force, in a stable and neutral position which avoids inadvertent programming or deprogramming of segments during a voluntary rotation or not of the selection crown.
Dans le programmateur 1, la couronne de sélection 9 recouvre complètement la couronne de programmation 4. Dès lors, la seule couronne manipulable par un utilisateur est la couronne de sélection 9. Or, il est parfois nécessaire, par suite d'une panne de courant ou d'un arrêt de fonctionnement, de remettre à l'heure le programmateur. Cette remise à l'heure s'effectue en faisant tourner la couronne de programmation 4 de manière à amener la graduation du cadran 6 correspondant à l'heure actuelle devant le repère 3 fixe du boîtier. Afin de permettre cette manipulation, la couronne de sélection 9 comporte des moyens propres à la rendre solidaire de la couronne de programmation 4 dans un premier sens de rotation, par exemple le sens de rotation horaire matérialisé par une flèche notée H à droite de l'index 10. Dans le sens de rotation inverse, par exemple anti horaire, la couronne de sélection 9 est en rotation libre par rapport à la couronne de programmation. Par exemple, les moyens de solidarisation de la couronne de programmation 4 avec la couronne de sélection 9 comportent au moins un cliquet 16 élastique et préférentiellement trois ou quatre cliquets formés sur une face interne de la bague transparente 9a. L'extrémité libre de chaque cliquet comporte une dent adaptée pour coopérer avec la denture de la roue d'engrenage intérieur 17 de la couronne de programmation. Les cliquets élastiques 16 sont agencés de telle sorte qu'en rotation horaire, la dent de chaque cliquet se bloque dans la roue d'engrenage intérieur 17 et entraîne la couronne de programmation en rotation avec la couronne de sélection 9. En rotation anti horaire, le bras de levier des cliquets est suffisamment souple pour que la dent de chaque cliquet échappe à la roue d'engrenage intérieur 17. Dans ce cas, la rotation de la couronne de sélection 9 est libre par rapport à la couronne de programmation 4. In the programmer 1, the selection ring 9 completely covers the programming ring 4. Therefore, the only crown that can be manipulated by a user is the selection ring 9. However, it is sometimes necessary, as a result of a power failure. or a shutdown, to reset the timer. This time is reset by turning the programming ring 4 so as to bring the scale of the dial 6 corresponding to the current time in front of the fixed reference 3 of the housing. In order to allow this manipulation, the selection ring 9 comprises means adapted to make it integral with the programming ring 4 in a first direction of rotation, for example the direction of clockwise rotation marked by an arrow denoted H to the right of the index 10. In the opposite direction of rotation, for example anti-clockwise, the selection ring 9 is in free rotation with respect to the programming crown. For example, the securing means of the programming ring 4 with the selection ring 9 comprise at least one elastic pawl 16 and preferably three or four pawls formed on an inner face of the transparent ring 9a. The free end of each pawl comprises a tooth adapted to cooperate with the toothing of the inner gear wheel 17 of the programming ring. The elastic pawls 16 are arranged such that in clockwise rotation, the tooth of each pawl locks in the inner gear wheel 17 and drives the programming ring in rotation with the selection ring 9. In anti-clockwise rotation, the lever arm of the pawls is sufficiently flexible so that the tooth of each pawl escapes the inner gear wheel 17. In this case, the rotation of the selection ring 9 is free with respect to the programming ring 4.
Le programmateur 1 fonctionne comme suit :  The programmer 1 operates as follows:
- Pour la programmation des plages horaires, l'utilisateur aligne l'index 10 de la couronne de sélection 9 sur la graduation du cadran 6 correspondant à la fin de la plage horaire à programmer. Il enfonce alors la couronne de sélection 9 dans la direction de programmation P, puis tourne la couronne de sélection dans le sens anti horaire jusqu'à la graduation correspondant au début de la plage horaire désirée. Dans ce mouvement, tous les segments de programmation 7 compris entre la fin et le début de la plage horaire à programmer sont déplacés en position de travail par l'ergot de programmation 11. L'utilisateur peut alors relâcher la pression sur la couronne de sélection 9 qui revient alors en position neutre sous l'effet du ressort de rappel 12. L'utilisateur peut alors recommencer cette procédure pour une autre plage horaire.  - For the programming of time slots, the user aligns the index 10 of the selection ring 9 on the scale of the dial 6 corresponding to the end of the time range to be programmed. He then depresses the selection crown 9 in the programming direction P, then turns the selection crown counter-clockwise to the graduation corresponding to the beginning of the desired time slot. In this movement, all the programming segments 7 between the end and the beginning of the time slot to be programmed are moved to the working position by the programming pin 11. The user can then release the pressure on the selection crown. 9 which then returns to the neutral position under the effect of the return spring 12. The user can then repeat this procedure for another time slot.
- Pour remettre à zéro des plages horaires préalablement programmées, l'utilisateur aligne l'index 10 de la couronne de sélection 9 sur une position correspondant à l'heure de fin de la plage horaire à remettre à zéro ou sur une position voisine postérieure à l'heure de fin. L'utilisateur tire alors sur la couronne de sélection 9 dans la direction de remise à zéro Z et la fait tourner en sens anti horaire jusqu'à l'heure de début de la plage horaire à remettre à zéro ou jusqu'à une position voisine antérieure à l'heure de début. L'ergot de remise à zéro 13 solidaire de la bague externe 9b entre en contact avec les segments de programmation en position de travail et les repousse dans leur position de repos. L'utilisateur peut alors relâcher la traction qu'il exerce sur la couronne de sélection 9. Celle-ci revient alors en position neutre sous l'effet du ressort de rappel 14. Cette procédure peut être reprise pour remettre à zéro une autre plage horaire. - To reset previously programmed time slots, the user aligns the index 10 of the selection ring 9 to a position corresponding to the end time of the time slot to reset or on a neighboring position after the end time. The user then pulls on the selection ring 9 in the Z reset direction and rotates it anti-clockwise until the start time of the time zone to be reset or to a neighboring position. before the start time. The reset pin 13 integral with the outer ring 9b comes into contact with the programming segments in the working position and pushes them into their rest position. The user can then release the traction he exerts on the selection ring 9. It then returns to the neutral position under the effect of the return spring 14. This procedure can be resumed to reset another time slot .
- Pour la mise à l'heure du programmateur 1, l'utilisateur tourne la couronne de sélection 9 dans le sens horaire jusqu'à amener la graduation du cadran 6 correspondant à l'heure actuelle en regard du repère 3 du boîtier. De manière connue en soi, le pignon 5 a du moteur 5 est entraîné par la roue d'engrenage intérieur 17 jusqu'à la nouvelle position de la couronne de programmation 4. Une fois cette position atteinte, le moteur 5 reprend l'entraînement de la couronne de programmation 4 au rythme correspondant au cycle temporel du programmateur. On note que la position axiale de la couronne de sélection est indifférente lors d'une opération de mise à l'heure du programmateur. En effet, dans ce cas la couronne de sélection 9 et la couronne de programmation 4 sont solidaires en rotation et les ergots de programmation ou de remise à zéro ne modifient pas la position des segments de programmation 7.  - For setting the time of the programmer 1, the user turns the selection ring 9 clockwise to bring the scale of the dial 6 corresponding to the current time next to the mark 3 of the housing. In a manner known per se, the pinion 5a of the motor 5 is driven by the internal gear wheel 17 to the new position of the programming ring 4. Once this position is reached, the motor 5 resumes the drive of the programming ring 4 at the rate corresponding to the time cycle of the programmer. Note that the axial position of the selection ring is indifferent during a time setting operation of the programmer. Indeed, in this case the selection ring 9 and the programming ring 4 are integral in rotation and the programming or reset pins do not change the position of the programming segments 7.
Bien entendu, cette description est donnée à titre d'exemple illustratif uniquement et l'homme du métier pourra y apporter de nombreuses modifications sans sortir de la portée de l'invention, comme par exemple réaliser un programmateur 1 adapté pour un fonctionnement en tableau et qui ne comporte donc pas de prises électriques mâle et femelle. Dans ce cas, la partie 2c du boîtier 2 peut être remplacée par une partie fermée sur le dessus.  Of course, this description is given by way of illustrative example only and the person skilled in the art will be able to make numerous modifications without departing from the scope of the invention, such as for example making a programmer 1 adapted for table operation and which therefore does not include male and female electrical outlets. In this case, the part 2c of the housing 2 can be replaced by a closed part on the top.
