Definitions

  • the present invention relates to the field of the time measuring instruments namely watches, chronometers, chronographs and in particular to such an instrument having strength, mechanical resistance and assembling easiness that are definitely higher than similar instruments that are, at present, known.
  • Document CH 921 374 A4 discloses a waterproof watchcase, whose peculiar feature is a substantially circular shaped elastic element for tightly connecting the components of said watchcase.
  • Document US-A-1 404 656 illustrates a preferably formed of precious metal watchcase, having an outer casing provided with reinforced segments forming a conical seating against which is placed a frusto-conical inner casing.
  • Document CH 368 427 A discloses a watchcase comprising an outer case provided with four independent handles, said watchcase being of the same exterior aspect with respect to common classic watchcases.
  • Document CH 347 136 A illustrates a crown to be used with any kind of watch-type instruments, having a central core able to receive the shank of the mechanism of said instrument.
  • the present invention provides for a time measuring instrument that is very sturdy, and easy to assemble, has very good imperviousness characteristics and a new aesthetic shape.
  • the main conception of the invention is to use mechanical components or members which are generally used for their mutual threading engagement, namely, the outer or protective watchcase is made of a standard hexagonal nut while the inner watchcase is made of a length of hollow bolt within which the instrument mechanism is housed.
  • the two mechanical members or main components are mutually connected by threading the bolt into the nut, thus resulting in a very strong assembly which is very difficult or almost impossible to dismantle and thus protects the mechanism in a very effective way.
  • FIG. 1 shows a plan view of a watch 10 according to the first embodiment while Fig. 3 shows the second embodiment 10' thereof.
  • the difference lies in the orientation of the outer watchcase 12, 12'.
  • the end-to-end distance, or nut-wrench distance is measured ("S-type reading” hexagonal nut, "S-type” watch) while in the watchcase 12' of Figure 3 the corner-to-corner distance or overall dimension distance is measured (“E-type reading" hexagonal nut, "E-type” watch).
  • hexagonal nuts that are neither "E-type” nor "S-type” nuts or even using non hexagonal nuts namely nuts having a number of sides different from six.
  • Corresponding handles 14,14' are connected to the outer watchcase 12, 12' for supporting a strap or the like (not shown) and a respective inner watchcase 16, 16' is threadily introduced into the outer watchcase.
  • a standard mechanism 18 with a standard dial 20 and standard hands 22, a ring 24 and a protective glass 26 are housed within the watchcase.
  • a small threaded bar or driving ring nut 28 provided with a driving member 30 at its end projects from the mechanism 18 and the watchcase 16; 12, 12'.
  • the dial could have a quite different shape and one, two, three or more driving ring nuts, could possibly be provided as push buttons.
  • handles 14, 14' are obtained in addition to a hole 34 for the driving ring nut 28.
  • the handles are connected to the outer watchcase 12, 12' by inserting respective screws or pins (not shown) into little holes 38 machined in the outer case (at the point of seat 32) and obviously also in the handles 14, 14' (even if they are not shown).
  • the inner watchcase 16 is threaded in the outer watchcase up to a limit stop position. Further, the inner watchcase also is drilled as the ring nut 28 can pass through the hole 34. Finally, the mechanism 18, the dial 20, the hands 22, the ring 24 and the protective glass 26 are assembled in a conventional way.
  • the driving member 30 of the ring nut 28 is also a nut, obviously having a reduced size. This is clear if one considers that the operation of the ring nut provides a rotary movement (a shifting movement just during the setting stage), such a motion corresponding to the conventional use of an hexagonal nut.
  • hexagonal nuts could be of any of the types which are at present on the market or special nuts having any thread width (M2, M4, M6, etc.) thread pitch (coarse, fine, etc.) and thread type (gas thread, metric thread etc).
  • thread width M2, M4, M6, etc.
  • thread pitch coarse, etc.
  • thread type gas thread, metric thread etc.
  • the material for making the instrument it could range from standard metals and non precious metal alloys (plated, unplated or subjected to different thermal or surface treatments), precious metals and/or alloys thereof, composite materials, ceramics, wood, natural fibers, plastics or synthetic materials, etc.
