Definitions

• the object of the present invention is to provide a device for attaching a bracelet to a watch case which obviates the aforementioned drawbacks and which moreover is simple, inexpensive and particularly robust in order to be able to equip sports or diving watches. .
• Another object of the present invention is to facilitate the mounting of a bracelet on a watch case, whether this bracelet is flexible or rigid.
• Figure 1 is a bottom view of a watch case equipped with the device according to the invention.
• Figure 2 is a partial section, on a larger scale, of Figure 1 along line A-A.
• Figure 3 illustrates in plan a first embodiment of a wire loop forming part of the device.
• Figure 4 illustrates in plan a second embodiment of a wire loop forming part of the device.
• the illustrated watch case provided with the strap fixing device according to the invention comprises a shape box 1, a middle part of the bezel 2 in which a lens 3 is fixed and a base 4 also comprising a lens 5.
• the box 1 may have an all-metal backing in other designs.
• the strap fastening device on this watch case comprises on the two sides of the case 1, here at 12 noon and at 6 o'clock, two blind holes 6,7 made in the watch case and opening onto its peripheral surface. These holes 6,7 are parallel to each other and located in planes parallel to the plane of symmetry of the watch case 12H-6H located at equal distance from this plane of symmetry.
• the axis of the blind holes 6,7 is inclined relative to the upper and lower faces of the box 1, the angle of inclination of these holes can vary at will between + 60 ° and - 60 ° about.
• the watch case is also provided with threads 8.9 opening onto the underside of the case 1 and the axes of which intersect the horns of the blind holes 6.7.
• the device for attaching a strap to a watch case also comprises strap hooking members constituted by wires or rods bent in the general shape of U 10.
• These members or handles 10 comprise each a middle part 11 intended to receive the bracelet (not shown) and two ends folded at 90 ° approximately 12.
• Each of these ends or branch 12 has on its lower face, near its end, a recess 13. Between this recess 13 and the end of the branch 12 this comprises a groove 15 receiving an O-ring seal to guarantee the stability of the assembly to vibrations.
• the middle part 11 of these handles 10 receives the bracelet, the latter can be folded around this middle part or comprise at its end a passage receiving this middle part 11.
• the ends of the branches 12 of the latter are each threaded in one of the blind holes 6,7 to a position where the recess 13 is located in the thread extension 8.9.
• screws 14 are screwed into the threads
• the handle 10 comprises at the end of its branches 12 circular grooves 15 intended to receive an anti-vibration seal 16.
• the fastening member of the bracelet or handle 10 consists of two rods or bent L-shaped wires 17,18.
• the short branches 19 of these rods 17, 18 include, as in the first embodiment, a recess 13 and a groove 15.
• a tube 21 makes it possible to join the free ends of the long branches 20 of these rods 17, 18 to create an organ for hanging the bracelet. Thanks to this two-part embodiment of the handle 10, one can first fix a part 17 thereof on the watch case, then thread the part of the bracelet having a passage on the branch 20 provided with the tube 21 fixed to the case . Then, the branch 20 of the other part 18 is threaded into the passage of the bracelet intended to receive it.
• This part 18 is introduced as far as possible so that the end of the branch 20 is inserted into the free end of the tube 21 and then the free end of the branch 19 is fixed to the watch case.
• the tube 21 has a narrowing in the middle of its length to ensure that it properly surrounds the ends of the two branches 20 in the service position and that it cannot slide too deeply on one of these branches 20.
• Each loop 10 can be formed from a folded and machined stainless steel wire or rod with a diameter of 1 to 2 mm for example. It is therefore understandable that the strap attachments on the watch are very solid. Their mechanical fixing is simple and robust. It is also easily removable.
