Description
Dispositif de fixation à baïonnette de la boîte d'une pièce d'horlogerie dans un support. L'objet de l'invention est un dispositif de fixation à baïonnette de la, boîte d'une pièce d'horlogerie dans un support; ce dispositif est caractérisé en ce que l'une des pièces, boîte et support, porte un organe élastique qui, lors que l'ergot du joint à baïonnette est engagé à fond dans sa rainure, s'engage avec l'autre pièce de façon à empêcher une rotation invo lontaire de la boîte dans le support et le dé gagement de l'ergot de sa rainure.
Le dessin ci-annexé représente, à titre d'exemple, une forme d'exécution de l'objet de l'invention.
La fig. 1 en est une coupe verticale axiale, <I>A</I> représentant la montre et<I>B</I> le support; la fig. 2 est une vue en plan de ce support; les fig. $ et 4 représentent, en plan, respec tivement en élévation, la lunette de la boîte A.
Le support B est fixé par des vis a à la paroi b d'txn véhicule, d'une automobile par exemple. La montre A comprend une lunette c et un fond-carrure d; elle se fixe au sup rort B et traverse un évidement central que celui-ci présente ainsi qu'un évidement cor respondant, creusé dans la paroi b. La fixa tion de la montre A au support B s'effectue par le moyen de deux joints à baïonnette dont les ergots e sont fixés aux support B aux deux extrémités d'un même diamètre, et font saillie à l'intérieur de ce support, tandis que les rainures f sont pratiquées dans la lunette c.
Le support B porte, en outre, à son inté rieur, un ressort g muni d'une tête saillante Ta et la lunette e présente, à sa périphérie, outre les deux rainures f, deux logements i' et i2. Pour fixer la lunette au support, on l'engage dans celui-ci de façon que les en trées<I>f 1</I> des rainures<I>f</I> soient engagées avec les ergots e. Dans cette position, la tête h du ressort g pénètre librement dans le logement ii. Après quoi, on fait exécuter à la lunette une rotation, de gauche à droite, en fig. 2, dans le support.
Par cette rotation, les er gots e sont amenés à fond de course dans leurs rainures respectives<I>f</I> et la tête<I>la</I> du ressort g vient s'engager dans le logement i'. Cette tête oppose, à une rotation involontaire de la lunette, dans le sens de droite à gauche en fig. 2, une certaine résistance, ce qui em pêche que la, lunette ne se dégage de son sup port sous l'influence des trépidations du véhicule.
Bayonet fixing device for the case of a timepiece in a support. The object of the invention is a bayonet fixing device for the case of a timepiece in a support; this device is characterized in that one of the parts, box and support, carries an elastic member which, when the lug of the bayonet joint is fully engaged in its groove, engages with the other part so to prevent inadvertent rotation of the box in the support and the release of the lug from its groove.
The accompanying drawing represents, by way of example, an embodiment of the object of the invention.
Fig. 1 is an axial vertical section, <I> A </I> representing the watch and <I> B </I> the support; fig. 2 is a plan view of this support; figs. $ and 4 represent, in plan, respectively in elevation, the telescope of box A.
The support B is fixed by screws a to the wall b of a vehicle, of an automobile for example. Watch A comprises a bezel c and a caseback d; it is fixed to the support B and passes through a central recess which the latter presents as well as a corresponding recess, hollowed out in the wall b. Watch A is fixed to the support B by means of two bayonet joints, the lugs e of which are fixed to the support B at both ends of the same diameter, and protrude inside this support, while the grooves f are made in the bezel c.
The support B also carries inside it a spring g provided with a projecting head Ta and the bezel e has, at its periphery, in addition to the two grooves f, two housings i 'and i2. To fix the telescope to the support, it is engaged in the latter so that the inputs <I> f 1 </I> of the grooves <I> f </I> are engaged with the lugs e. In this position, the head h of the spring g penetrates freely into the housing ii. After which, the telescope is rotated from left to right, in fig. 2, in the holder.
By this rotation, the er gots e are brought to their full travel in their respective grooves <I> f </I> and the head <I> la </I> of the spring g engages in the housing i '. This head opposes, to an involuntary rotation of the telescope, in the direction from right to left in fig. 2, a certain resistance, which prevents the, bezel does not emerge from its support under the influence of the vibrations of the vehicle.
