Definitions

  • the present invention relates to a wristwatch case comprising a crystal, a middle part serving as a housing for a movement fitted with needles and a bottom removably fixed to the middle part, said middle part having on its lower edge two diametrically opposite clearances for receiving each a strand of the bracelet, the shape of each clearance being substantially the same as the shape of the strand which is engaged therein and said bottom being shaped to cover said clearances when the box is closed.
  • Document CH-B-347 490 describes a device for attaching a bracelet to a watch case which has two ears integral with the watch and projecting laterally therefrom and arranged in such a way that the ends of the bracelet are each attached to one of these ears by an assembly member which avoids the use of bars.
  • the figures show that the middle part is not provided with any clearance on its lower edge so that the attachment device is prominent and leaves visible the attachment system of the bracelet to the box, which is not the case in the present invention.
  • Patent FR-A-935,435 describes a bracelet attachment to a watch which avoids the use of an ordinary clasp. It is actually a device added to a watch that must have its own case and the strands of the bracelet are not attached to the middle part of this watch as will be seen in the present invention.
  • the present invention overcomes the drawbacks mentioned above by proposing to use the means which appear in the claims.
  • At least one projection 17 is integral with the bottom 13. This projection extends in the engagement 16 to receive a corresponding opening 18 made in the strand 2 so that the strand is fixed to the box when the cover is applied under the middle.
  • the bottom 13 has two projections 17, each of the projections being a protuberance made in one piece with the bottom.
  • the base, with the projections which it includes, is produced by turning and milling.
  • a plate 19 which can be metallic and which is inserted into the thickness of the strand.
  • the protrusions of which have the shape of crown segments makes it possible to reduce the total height of the watch as much as possible and is particularly suitable for a ladies' watch. It goes without saying that, in this embodiment, the openings 18 made in the strand will also have the same shape of crown segment.
  • FIG. 2 also shows that the face 20 of the clearance 16, extending opposite the part 21 of the bottom 13 covering said clearance, forms with said part two planes between which the strand 2 is sandwiched, the said planes being perpendicular to the axis 23 of the hands 22, to force the strand 2 to emerge from the box in a plane perpendicular to said axis 23.
  • This arrangement will be used for watches of small diameters, particularly for ladies' watches, the diameter of which is at least 22 mm.
  • Figure 4 is a top view of the watch case according to the invention and according to a second embodiment. This second mode is distinguished from the first only by its attachment system and by the fact that the strands of the bracelet are inclined relative to the axis of the watch hands. Also we will not return to the construction details which are the same as those set out in connection with FIGS. 1, 2 and 3 and we will simply use the same reference numbers to designate the identical parts.
  • Figure 4 is partially torn at 6 o'clock from its dial to show how the bracelet 2 is attached to the case 1.
  • the middle part 5 has on its lower edge two diametrically opposite recesses 16 which receive each a strand 2 of the bracelet.
  • the bottom carries two projections 30 for a clearance 16, these projections being in the form of cylindrical pins driven into the bottom 13. So that the pin is well anchored in the bottom, we give at the bottom an extra thickness 31 at the place where the bottom covers the clearance 16.
  • the pins 30 extend in the clearance 16 to receive a corresponding opening 32 made in the strand 2.
  • the openings 32 are simple circular holes drilled in the strand, holes whose diameter is adjusted to the diameter of the pins 30.
  • the strand can be reinforced by the plate 19.
  • FIGS. 5 and 6 also show that the face 33 of the clearance 16, extending opposite the portion 34 of the bottom 13 covering said clearance, forms with said portion two planes between which the strand 2 is sandwiched, said planes being inclined relative to the axis 23 of the needles 22, at least in the peripheral region of the box 1, to force said strand 2 to emerge from the box in a plane inclined relative to said axis 23.
  • the fixing of the bracelet by pins and the arrangement allowing the inclined emergence of the strands of the bracelet will be used especially on watches having a large diameter, for example 40 mm. In this case, in fact, there is more space in thickness, which makes it possible to reinforce the bottom to receive the pins and take advantage of a simpler fixing system than that of the crown segments of the previous embodiment. Similarly, the inclined exit of the bracelet strands is justified given the large diameter of the box. This arrangement will allow the bracelet to follow the shape of the wrist as soon as it leaves the bracelet from the watch case. If one wishes to reinforce the strand 2 at the place of its fixing, one will use, as for the previous embodiment, a reinforcing plate 19 to which one will also give an inclined shape as seen in FIGS. 5 and 6.
  • the middle part 5 is made of very hard material such as ceramic or a metal carbide.
  • the clearances 12 will come directly from sintering without requiring subsequent operations. Only the surfaces receiving the glass 6 and the movement 7 will be machined.
  • the middle could be made of another material such as stainless steel or a precious metal such as gold.
