Definitions

  • the subject of the present invention is a watch case of the so-called “monocoque” type, that is to say the case and the middle of which are in one piece.
  • Such watch cases known per se, have the disadvantage that, if the glass is mounted on the notch on the body of the case or case-back, disassembly is not easy because it is impossible to act under the glass to exert on it a pressure tending to extract it.
  • the object of the present invention is to provide a means of fixing a monocoque watch case glass which allows easy dismantling of the glass while ensuring reliable fixing thereof.
  • the movement of the wristwatch represented, designated by 1, provided with its dial designated by 2, is housed in a watertight box of the monocoque type, that is to say whose body or caseband, designated by 3, is come from a room with the bottom designated by 3 a .
  • the movement is fixed to this case-back 3 by screws 4 taking in it.
  • the crystal of the case preferably made of extra hard material such as tempered mineral glass or sapphire, designated by 5, is engaged with gentle friction in the case body or middle part 3 with the interposition of a seal 6 made of flexible and compressible material.
  • This glass is supported on a ring 7 surrounding the movement and which plays the role of flange.
  • the crystal 5 is held in place in the backband and even applied axially against the edge of the flange 7 by a diametrical flange of tension 8 comprising an annular part 8 a resting on it and two pairs of arms 8 b , diametrically opposite, the ends of which come to engage on either side of each of two hinges 3 b which has the middle part 3 and which serve when attaching the bracelet designated by 9.
  • the assembly between the ends of the arms 8b and each of the hinges 3 b is obtained through a bar 10 to which floors the terminal portion, the thinner, designated 10a, is threaded and receives, screwed onto it, a threaded sleeve 11, the diameter of which corresponds to the part of larger diameter, designated by 10 b , of the bar 10.
  • the diameter of the part 10 b of the bar 10 and of the sleeve 11 corresponds to the diameter of the holes, designated by 12, which have the arms 8 b of the diametrical flange holding 8 the glass, while the central part of the bar 10, designated by 10 c , has a diameter which corresponds to that of the hole, designated by 13, which each of the hinges 3 has b .
  • the parts 10b and 10c of the bar 10 are connected by a chamfer 14 while the front end of the sleeve 11 has a chamfer 15.
  • the arrangement is such that, when the crystal 5 is in place in the backband 3, the diametrical support flange being applied to it, it is necessary to exert a slight force on the ends of the arms 8 b to bring the holes 12 of these opposite hole 13 of each of the hinges 3 b .
  • the bars 10 are put in place and the sleeves 11 screwed onto each of them.
  • the chamfers 14 and 15, cooperating with conical inlets 16 which have the holes 12, help in the positioning of the bars and sleeves as soon as the holes 12 may not be in perfect alignment with the holes 13.
  • the bars then exert a pre-tension on the diametral flange 8 which, in turn, exerts an elastic axial force on the glass, applying the latter axially against the flange 7. In this way, the glass is firmly held in place and does not risk, even if its friction on the seal 6 is not significant, to inadvertently separate from the box body.
  • the box body having, at the right of one of the two hinges 3 b , a tab 17 which makes it possible to introduce a blade into an annular groove 18 which the glass 5 has for this purpose.
  • stirrup 19 located under the bottom 3 a , articulated on a circular piece 20 rotatably mounted on the bottom.
  • This stirrup can occupy two positions, one working, in which it is perpendicular to the plane of the box and can be grasped in order to allow the drive of the part 20, and the other, of rest, shown in the drawing , in which it is folded down in the plane of the box.
  • the hinges 3 b for fixing the bracelet and the diametrical flange to be replaced by handles.
  • the arms 8b can engage between the two handles, the bracelet itself being engaged between said arms.
  • Each pair of arms 8b can be replaced by a single arm ending in a fork, the branches of which engage on the hinges of the box or between the handles of the latter.
  • the diametrical flange has, for decorative purposes, two additional radial arms, arranged perpendicular to its main part; these arms could even be fixed, by their ends, to the box body.
  • the attachment of the flange to the box body may be different from that which has been described and shown and, in particular, be independent of the means of attachment of the bracelet.
  • annular central portion 8a of the flange carries a tower hours.
