Definitions

  • the present invention relates to a watch, in particular a pocket watch according to the preamble of claim 1.
  • Wristwatches have widely established themselves although they suffer from disadvantages such as reduced wearing comfort and poor protection of the watch, in particular against ice, against shocks and scratches. For these reasons, other types of watches enjoy popularity which does not decrease.
  • Pocket watches in particular also called watches gusset, know a craze going hand in hand with the vogue of the vest.
  • watches intended to be worn with oneself elsewhere on the wrist for example, pin watches, staple watches, pendant watches, chatelaines, clip watches, etc. are thus concerned by the present invention.
  • the watch is set to the time and, in the case of a watch mechanical, reassembled by means of a winding rod passing through the the watch. It is common to associate this winding stem with means of locking the cover, so that the cover can be opened by manipulating the winding stem, for example by pushing the crown winder. At least one spring element is generally provided to obtain automatic and rapid opening of the lid as soon as the means of lock were released by actuation of the winding stem.
  • the spring element Due to the weight of the cover, the spring element must be relatively powerful and therefore bulky.
  • the locking means are therefore also bulky and also relatively complex. By Consequently, it is difficult to obtain a good seal in this portion of the watch around the winding stem. So we have often been content to make pocket watches that are not protected from humidity.
  • An object of the present invention is therefore to propose a watch improved, in particular a watch with a good balance of advantageous characteristics such as sealing, cost price, solidity, simplicity of construction, aesthetics, etc.
  • this object is achieved by means of a watch, in particular a pocket watch, comprising a waterproof enclosure allowing to house and protect said watch movement, the locking means being outside said sealed enclosure, sealing means being provided at the place where said rod passes through said sealed enclosure.
  • Figure 1 illustrates a sectional view of a half of a watch seen from profile. Only the elements necessary for understanding the invention have been illustrated. The example illustrated represents the particular case of a pocket watch soap type; the invention however also applies to other types watches fitted with a cover. Different elements will have to be modified depending on the type of watch chosen and the aesthetics of the watch.
  • the illustrated pocket watch case consists of a middle 1 and a removable bottom 6, in this example a bottom fixed to notch.
  • the bottom could just as easily be screwed or integrated into the middle.
  • No seals or special sealing means are not provided at the interface between the middle part 1 and the bottom 6.
  • a cover 5 above the glass 8 and the dial 90 can be open to read the time and closed to transport the watch.
  • Lid is preferably articulated around a hinge (not shown) located at the opposite of the rod 7, that is to say generally at 6 o'clock around the watch.
  • a rod 7 passes through the middle 1 through an opening 10, preferably at 12 o'clock around the watch.
  • the middle may be optionally provided a pendant and / or a bail at this location, especially in the case of a watch worn at the end of a chain.
  • the rod 7 provided with a crown 70 allows movement 9 to be set to the time and, in the case of a mechanical movement, to wind the watch.
  • sealing means such as those described below must be provided for each of these rods.
  • the opening 10 through the middle has a diameter only slightly greater than the external diameter of the rod 7.
  • a peripheral groove 11, of rectangular section, is provided at least on an annular segment of the internal face of the middle part 1, so that the opening 10 reaches at the bottom of the groove 11.
  • An annular spring leaf 73 shown in perspective in Figure 1a, is arranged in the groove 11. The radius of curvature at rest of the leaf spring is greater than the radius of curvature of the groove 11, so that the leaf spring 73 tends to move away and to want to occupy the bottom of the groove 11.
  • the rod 7 crosses the leaf spring at the exit of the opening 10.
  • the diameter of the rod portion 71 in the opening 10 is greater than the diameter of the portion 72 passing through the passage 731 in the leaf spring, so that the leaf spring comes to rest against a projection of the rod 7 to where it changes diameter.
  • the projection can be obtained by stem turning 7 or by inserting a tube around a diameter stem constant.
  • the leaf spring 73 therefore pushes the rod 7 outwards.
  • a locking element 730 secured to the leaf spring becomes encrusted in the inner face of the cover 5 so as to keep it closed.
  • the rod 7 and the crown 70 are integral. Opening the cover 5 by pressing on the crown therefore involves a axial displacement of the rod towards the interior of movement 9. Some movements however do not support such displacement.
  • stem or crown could consist of several pieces suitable for slide axially independently of each other.
  • the rod portion 71 could be constituted by a tube integral with the crown 70 and able to slide axially around the internal rod 7.
  • movement 9 is housed in an enclosure waterproof 2, 3.8 inside the middle 1.
  • the waterproof enclosure is in this example constituted by a casing circle 2, a bottom 3 and the glass 8.
  • the casing ring 2 can be fixed by any means to the middle part 1; for example, if circle 2 is made of synthetic material, it can be simply forced into the opening inside the middle. Other ways fixing, for example by screwing, may however be provided.
  • the time setting rod 7 crosses the casing circle 2 by a opening 20.
  • Sealing means are provided to prevent water infiltration through this opening.
  • the sealing means are constituted simply by a portion of the opening 20 of reduced diameter.
  • a seal 30 is furthermore provided at the interface between the circle 2 and the bottom 3, and preferably also at the interface between the glass 8 and the circle 2 (not shown).
  • movement 9, as well as the dial 90 and glass 8 are fixed directly to the casing circle 2.
  • a bezel 4 partially covers the middle 1 and almost completely the circle 2, only showing the small portion of circle 2 acting as a joint between the telescope 4 and the glass 8.
  • the circle 2 is completely covered by the bezel 4.
  • the glass can also be held by the bezel rather than by the casing circle.
  • the telescope 4 is extended until dial 90 so as to completely conceal the circle 2 which can then be produced at a lower cost and without aesthetic concerns.
  • FIG. 2 illustrates a variant in which the casing circle 2 and the bezel 4 form a single piece.
  • a socket 23 inserted in opening 20 helps prevent water and dust from entering around of the rod 7.
  • the sleeve 23 is preferably provided with seals 21 and 22.
  • FIG. 3 illustrates another variant of the invention, which can be combined with any of the above variants.
  • a walls of the sealed enclosure protecting the movement 9 consists of the bottom of the box 6. It is therefore not necessary to provide a bottom additional 3, which reduces costs and thickness of the watch complete.
  • this variant requires machining operations additional of the bottom 6 for its fixing with the circle 2, which can increase its cost in particular if it is made of expensive material.
  • sealed enclosure can be imagined, for example an enclosure entirely produced by injection of synthetic material.
