Description

  

  Procédé de fixation d'un mouvement de montre à remontage automatique.    L'objet de la présente invention est un  procédé de fixation d'un mouvement de mon  tre à remontage automatique dans sa boîte,  caractérisé en ce qu'on pratique sur le pour  tour de l'entrée de cage de la carrure au       moins    deux trous cylindriques et qu'on place  dans chacun (le ceux-ci une vis dont la tête  fixe le filet de la platine     du    mouvement contre  le bord de la carrure.  



  Quand la carrure est en métal dur, on peut  chasser dans chacun desdits trous cylindri  ques un canon taraudé de métal tendre et  placer une desdites vis dans chacun de ces  canons.  



  La difficulté de fixer un mouvement à  remontage automatique sur la carrure pro  vient de ce que le filet. de la platine est extrê  mement mince; en effet, la. masse oscillante  doit avoir le     plus    grand moment d'inertie pos  sible pour un poids donné et s'étend par con  séquent sur une grande hauteur par rapport  au mouvement, ce qui laisse peu de place pour  le filet de la     platine.     



  Le dessin annexé représente, à titre  d'exemple, un mouvement fixé au moyen du  procédé selon l'invention. II n'est montré que  ce que la compréhension de l'invention exige.  



  La     fig.    1 est. une coupe montrant le     mou-          vement    fixé dans la. carrure.  



  La     -Fig.    2 est. une vue en plan d'une partie    de la carrure, avant la. fixation du mouve  ment.  



  1 représente le mouvement d'une montre  à remontage automatique à. fixer, 2 la     carrure     de la boîte, supposée en métal dur. Sur le  pourtour de l'entrée de     eage    se trouvent     deux     trous cylindriques dans lesquels sont chassés  des canons     .1    de métal tendre, tel que du lai  ton. Au centre de ces canons 4 sont pratiqués  des taraudages 5 dans lesquels pénètrent des  vis 3. Ainsi, la platine 6 du     mouvement    se  trouve solidement fixée à la carrure 2.



  Method of fixing a self-winding watch movement. The object of the present invention is a method for fixing a self-winding watch movement in its case, characterized in that at least two holes are made on the circumference of the cage entry of the middle part. cylindrical and that we place in each (the latter a screw whose head fixes the thread of the movement plate against the edge of the caseband.



  When the middle part is made of hard metal, it is possible to drive a threaded barrel of soft metal into each of said cylindrical holes and place one of said screws in each of these barrels.



  The difficulty in fixing a self-winding movement on the pro caseband comes from the net. platinum is extremely thin; indeed, the. oscillating mass must have the greatest possible moment of inertia for a given weight and consequently extends over a great height in relation to the movement, which leaves little room for the thread of the plate.



  The accompanying drawing represents, by way of example, a movement fixed by means of the method according to the invention. It is shown only what the understanding of the invention requires.



  Fig. 1 is. a section showing the movement fixed in the. build.



  The -Fig. 2 is. a plan view of part of the caseband, before the. fixation of the movement.



  1 represents the movement of a self-winding watch at. fix, 2 the caseband, supposed to be in hard metal. Around the perimeter of the eage entrance are two cylindrical holes into which are driven .1 guns of soft metal, such as brass. In the center of these barrels 4 are formed threads 5 in which screws 3 penetrate. Thus, the plate 6 of the movement is securely fixed to the middle part 2.

REVENDICATION: Procédé de fixation d'un mouvement de montre à remontage automatique dans une, carrure, caractérisé en ce qu'on pratique sur le pourtour de l'entrée de cage de la carrare au moins deux trous cylindriques et qu'on place dans chacun de ceux-ci une vis dont la tête fixe le filet de la platine du mouvement contre le bord de la carrure. SOUS-REVENDICATION: Procédé selon la revendication, appliqué à une carrure en métal dur, caractérisé en ce qu'on chasse dans chacun desdits trous cylin driques un canon taraudé de métal tendre et qu'on place une desdites vis dans chacun de ces canons. CLAIM: A method of fixing a self-winding watch movement in a caseband, characterized in that at least two cylindrical holes are placed on the periphery of the entrance to the carrara cage and which are placed in each of these a screw whose head fixes the thread of the movement plate against the edge of the caseband.
