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.
