La présente invention a pour objet une montre électrique comportant deux sources d'énergie logées dans un compartiment commun muni d'une seule ouverture permettant l'engagement successif et la mise en place desdites sources d'énergie latéralement par rapport à leur axe. The present invention relates to an electric watch comprising two energy sources housed in a common compartment provided with a single opening allowing the successive engagement and the positioning of said energy sources laterally with respect to their axis.

De telles montres électriques sont connues et sont décrites, par exemple, dans la demande de brevet français N" 2273312. Such electric watches are known and are described, for example, in French patent application No. 2273312.

On connaît également des montres électroniques comprenant deux alvéoles pour loger des piles, l'un de ces alvéoles comportant un bord à base en cône alors que l'autre alvéole présente un bord plus rectiligne, de telle sorte que les piles ne puissent y être insérées avec la mauvaise polarité. Une telle disposition est décrite, par exemple, dans la demande de brevet français N" 2216612. Electronic watches are also known comprising two cells for accommodating batteries, one of these cells having a cone-based edge while the other cell has a more straight edge, so that the batteries cannot be inserted therein. with the wrong polarity. Such an arrangement is described, for example, in French patent application No. 2216612.

Le but de la présente invention est de munir une montre de ce genre de moyens évitant toute erreur dans la position dans laquelle les piles sont placées dans le compartiment qui leur est réservé, cela à l'aide de moyens simples et bon marché. The object of the present invention is to provide a watch with this kind of means avoiding any error in the position in which the batteries are placed in the compartment reserved for them, this using simple and inexpensive means.

Ce but est atteint grâce aux moyens revendiqués. This goal is achieved by the means claimed.

Le, dessin représente, à titre d'exemple, une forme d'exécution de l'objet de l'invention. The drawing represents, by way of example, an embodiment of the subject of the invention.

La fig. 1 est une vue en plan, de dessous, d'une montre électrique dont le fond de la boîte et les sources d'énergie ont été ôtés, et la fig. 2 est une coupe suivant la ligne II-II de la fig. 1, les sources d'énergie et le fond de la, boîte étant en place, mais le bouchon de fermeture du compartiment. des sources d'énergie de même que le ressort interposé entre celles-ci et ledit bouchon étant représentés séparés du reste de la montre. Fig. 1 is a plan view, from below, of an electric watch from which the bottom of the box and the energy sources have been removed, and fig. 2 is a section along line II-II of FIG. 1, the energy sources and the bottom of the box being in place, but the compartment closing plug. energy sources as well as the spring interposed between them and said plug being shown separated from the rest of the watch.

La montre représentée comprend un mouvement électronique 1, schématiquement représenté, logé dans une boîte comportant une carrure-lunette 2, une glace 3 et un fond 4. The watch shown comprises an electronic movement 1, schematically represented, housed in a box comprising a middle part-bezel 2, a crystal 3 and a base 4.

Le circuit électronique de cette montre est alimenté par deux piles électriques 5 et 6 montées en série, logées dans un compartiment commun limité, d'une part,. par une plaque en matière isolante 7 constituant le support du circuit électronique du mouvement, et qui forme le fond dudit compartiment, d'autre part, par une plaque en matière isolante 8, plus épaisse que la première, superposée à celle-ci et, enfin, par le fond 4 de la boîte. The electronic circuit of this watch is powered by two electric batteries 5 and 6 mounted in series, housed in a limited common compartment, on the one hand. by a plate of insulating material 7 constituting the support of the electronic circuit of the movement, and which forms the bottom of said compartment, on the other hand, by a plate of insulating material 8, thicker than the first, superimposed on it and, finally, by the bottom 4 of the box.

La plaque 8 est percée de deux trous 9 et 10 formant des logements pour les deux piles 5 et 6 respectivement. Le trou 10 est de plus petit diamètre que le trou 9, étant destiné à recevoir le pôle posiù'f, désigné par 6a de la pile 6, alors que le trou 9 est destiné à recevoir le corps de la pile 5, constituant son pôle négatif, de plus grand diamètre que son pôle positif 5a. La partie médiane 8a de la plaque 8 située entre les deux trous 9 et 10 est de plus faible hauteur que le reste de la plaque, ce qui ménage ainsi une creusure, indiquée en 1 1 à la fig. 1, permettant l'introduction des piles 5 et 6 dans leur compartiment commun de même que leur extraction hors de celui-ci à travers une ouverture 12 ménagée dans le fond 4, au centre de celui-ci.La paroi du trou 10 présente un épaulement annulaire 8b dans lequel s'engage le pôle positif de la pile engagée dans ce trou. The plate 8 is pierced with two holes 9 and 10 forming housings for the two stacks 5 and 6 respectively. The hole 10 is of smaller diameter than the hole 9, being intended to receive the posiù'f pole, designated by 6a of the pile 6, while the hole 9 is intended to receive the body of the pile 5, constituting its pole negative, larger in diameter than its positive pole 5a. The middle part 8a of the plate 8 located between the two holes 9 and 10 is of lower height than the rest of the plate, which thus spares a recess, indicated in 1 1 in FIG. 1, allowing the insertion of the batteries 5 and 6 into their common compartment as well as their extraction from it through an opening 12 formed in the bottom 4, in the center of it. The wall of the hole 10 has a annular shoulder 8b in which engages the positive pole of the battery engaged in this hole.

Les deux piles s'engagent successivement dans l'ouverture 12 et se placent, par déplacement latéral, chacune dans son logement respectif 9 ou 10. Il est à remarquer que la hauteur de la partie 8a est telle qu'elle empêche que les deux piles soient placées autrement qu'en tête-bêche, assurant leur branchement en série, et chacune dans une position déterminée. En effet, la pile 5 doit toujours être placée la première. Si la pile 6 est placée la première, dans sa position normale, son corps, de grand diamètre, empêche la mise en place de la pile 5.Si la pile 6 est placée la première retournée par rapport à sa position normale, son corps de grand diamètre vient reposer sur la face supérieure 13, tronconique, de l'épaulement 8b faisant saillie à l'intérieur de la paroi latérale du trou 10, ce qui surélève la pile et empêche l'engagement de la pile 5. Si celle-ci est placée la première retournée par rapport à sa position normale, son corps de grand diamètre empêche l'engagement de la pile 6. Il faut donc que la pile 5 soit engagée non seulement la première, mais dans sa position normale, pour que la pile 6 puisse ensuite être mise en place. Celle-ci ne peut être engagée qu'en position normale, son pôle positif 6a logé à l'intérieur de l'épaulement 8b, faute de quoi le fait que son corps bute contre le siège 13 empêche son introduction complète. The two piles successively engage in the opening 12 and are placed, by lateral displacement, each in its respective housing 9 or 10. It should be noted that the height of the part 8a is such that it prevents the two piles are placed other than upside down, ensuring their connection in series, and each in a determined position. Indeed, stack 5 must always be placed first. If the battery 6 is placed first, in its normal position, its body, of large diameter, prevents the placement of the battery 5. If the battery 6 is placed the first turned over from its normal position, its body large diameter comes to rest on the upper face 13, frustoconical, of the shoulder 8b protruding inside the side wall of the hole 10, which raises the stack and prevents the engagement of the stack 5. If the latter is placed the first turned over from its normal position, its large diameter body prevents the engagement of the stack 6. It is therefore necessary that the stack 5 is engaged not only the first, but in its normal position, so that the stack 6 can then be put in place. The latter can only be engaged in the normal position, its positive pole 6a housed inside the shoulder 8b, failing which the fact that its body abuts against the seat 13 prevents its complete introduction.

Ainsi, toute possibilité d'erreur dans la position des piles est éliminée. Thus, any possibility of error in the position of the batteries is eliminated.

L'ouverture 12 du fond 4 se ferme à l'aide d'un bouchon 14 se montant à baïonnette. En variante, ce bouchon pourrait être The opening 12 of the bottom 4 closes with a plug 14 mounted with a bayonet. Alternatively, this plug could be

vissé. Un ressort-lame 15 est interposé entre ce bouchon 14 et les piles 5 et 6. Ce ressort présente deux lames 15a repliées en direction des piles et deux lames 15b repliées en direction du bouchon. Il assure ainsi, d'une part, le maintien en place des piles et, d'autre part, leur pontage électrique, reliant le corps négatif de la pile 6 au pôle positif 5a de la pile 5. screwed. A leaf spring 15 is interposed between this plug 14 and the batteries 5 and 6. This spring has two blades 15a folded in the direction of the batteries and two blades 15b folded in the direction of the plug. It thus ensures, on the one hand, the holding in place of the batteries and, on the other hand, their electrical bridging, connecting the negative body of the battery 6 to the positive pole 5a of the battery 5.

Le ressort 15 présente en outre une languette 15c, repliée à angle droit, engagée dans un perçage 16 ménagé dans la bague 8, ce qui empêche qu'il soit entraîné en rotation lors de la mise en place et de l'enlèvement du bouchon 14. Dans le même but, le ressort présente une seconde languette, désignée par 15d, dont l'extrémité s'engage dans une creusure en arc de cercle 17 ménagée dans la bague 8 et qui mord sur la creusure 11 de celle-ci. The spring 15 also has a tongue 15c, folded at a right angle, engaged in a bore 16 formed in the ring 8, which prevents it from being driven in rotation during the fitting and removing of the plug 14 For the same purpose, the spring has a second tongue, designated by 15d, the end of which engages in a recess in an arc 17 formed in the ring 8 and which bites onto the recess 11 thereof.

Il est à remarquer que, dans l'exemple décrit et représenté, les sources d'énergie 5 et 6 sont constituées par des piles électriques. En variante, elles pourraient être constituées par des accumulateurs rechargeables. It should be noted that, in the example described and shown, the energy sources 5 and 6 are constituted by electric cells. As a variant, they could be constituted by rechargeable accumulators.

The present invention relates to an electric watch comprising two energy sources housed in a common compartment provided with a single opening allowing the successive engagement and the positioning of said energy sources laterally with respect to their axis.

Such electric watches are known and are described, for example, in French patent application No. 2273312.

Electronic watches are also known comprising two cells for accommodating batteries, one of these cells having a cone-based edge while the other cell has a more straight edge, so that the batteries cannot be inserted therein. with the wrong polarity. Such an arrangement is described, for example, in French patent application No. 2216612.

The object of the present invention is to provide a watch with this kind of means avoiding any error in the position in which the batteries are placed in the compartment reserved for them, this using simple and inexpensive means.

This goal is achieved by the means claimed.

The drawing represents, by way of example, an embodiment of the subject of the invention.

Fig. 1 is a plan view, from below, of an electric watch from which the bottom of the box and the energy sources have been removed, and fig. 2 is a section along line II-II of FIG. 1, the energy sources and the bottom of the box being in place, but the compartment closing plug. energy sources as well as the spring interposed between them and said plug being shown separated from the rest of the watch.

The watch shown comprises an electronic movement 1, schematically represented, housed in a box comprising a middle part-bezel 2, a crystal 3 and a base 4.

The electronic circuit of this watch is powered by two electric batteries 5 and 6 mounted in series, housed in a limited common compartment, on the one hand. by a plate of insulating material 7 constituting the support of the electronic circuit of the movement, and which forms the bottom of said compartment, on the other hand, by a plate of insulating material 8, thicker than the first, superimposed on it and, finally, by the bottom 4 of the box.

The plate 8 is pierced with two holes 9 and 10 forming housings for the two stacks 5 and 6 respectively. The hole 10 is of smaller diameter than the hole 9, being intended to receive the posiù'f pole, designated by 6a of the pile 6, while the hole 9 is intended to receive the body of the pile 5, constituting its pole negative, larger in diameter than its positive pole 5a. The middle part 8a of the plate 8 located between the two holes 9 and 10 is of lower height than the rest of the plate, which thus spares a recess, indicated in 1 1 in FIG. 1, allowing the insertion of the batteries 5 and 6 into their common compartment as well as their extraction from it through an opening 12 formed in the bottom 4, in the center of it. The wall of the hole 10 has a annular shoulder 8b in which engages the positive pole of the battery engaged in this hole.

The two piles successively engage in the opening 12 and are placed, by lateral displacement, each in its respective housing 9 or 10. It should be noted that the height of the part 8a is such that it prevents the two piles are placed other than upside down, ensuring their connection in series, and each in a determined position. Indeed, stack 5 must always be placed first. If the battery 6 is placed first, in its normal position, its body, of large diameter, prevents the placement of the battery 5. If the battery 6 is placed the first turned over from its normal position, its body large diameter comes to rest on the upper face 13, frustoconical, of the shoulder 8b protruding inside the side wall of the hole 10, which raises the stack and prevents the engagement of the stack 5. If the latter is placed the first turned over from its normal position, its large diameter body prevents the engagement of the stack 6. It is therefore necessary that the stack 5 is engaged not only the first, but in its normal position, so that the stack 6 can then be put in place. The latter can only be engaged in the normal position, its positive pole 6a housed inside the shoulder 8b, failing which the fact that its body abuts against the seat 13 prevents its complete introduction.

Thus, any possibility of error in the position of the batteries is eliminated.

The opening 12 of the bottom 4 closes with a plug 14 mounted with a bayonet. Alternatively, this plug could be
