Definitions

• the invention relates to a watch to wear on the wrist or in another way, which is detachable from its bracelet in a very easy way. It is thus possible to wear the watch either around the wrist or, if desired, anywhere; one can carry it for example in the pocket, detached from the bracelet, in the wallet or; any other place without the need to detach the bracelet from the wrist.
• Such a watch is characterized by what is claimed in claim 1.
• Fig. 1 shows an exploded side view
• fig. 2 shows the plate
• fig. 3. gives a side view of the. movable bar
• fig. 4 is a section of the area along the periphery of the watch body, in the plane IV - IV of FIG. 1.
• the watch has two distinct elements, connected together but in a detachable manner, between them.
• the first is a watch body 1 which carries and protects the watch itself, housing its movement, its dial and its hands.
• the other element is a plate 2 to which the bracelet is attached in a manner still to be described.
• This plate 2 serves as a spring in a manner also to be described. Note from fig.
• the wafer has an opening or slot 3 which crosses from its mouth 4 on the periphery of the wafer diametrically towards a point opposite, thus dividing the wafer into two semi-circular parts 2a, 2b which are only connected to each other by a peripheral zone 5.
• This zone 5 is relatively narrow and therefore provides flexibility between the parts 2a, 2b so that they can, in the region of the opening 4, move away or approach under the action of the radial pressures exerted on the wafer.
• Enlargements 6 distributed along the slit * 3 help to increase this flexibility, in particular that close to zone 5.
• the plate 2 is further provided with two beads or re ⁇ edges 7 projecting from the periphery. They are distributed along a part of this periphery and praced diametrically opposite one another so that their connecting axis is perpendicular to the slot 3. One of the edges is interrupted, exactly on said axis connection, by a notch 8. Its function will be further explained.
• the recess in part 2a is in the form of a single rectangular opening 9. This opening is crossed,. in its longitudinal direction, by a bar 10.
• the bar is provided at each end with a fork 11 which slides on the respective edge of the recess 9.
• the par- tie 2b has a recess 12 similar to that of the par ⁇ tie 2a, but this recess is crossed by a solid bar 13 which divides the recess into two openings of identical dimensions.
• the bracelet 14 passes, at one of its ends, around the solid bar 13.
• the other end is passed around the movable bar 10, leaving a certain section 15 of this free end in order to be able to adjust the active length of the bracelet.
• the bracelet is tightened around the wrist; to release it, it is impossible to pull the other part of this end because it becomes, by this action, blocked between the movable bar 10 and the edge of the recess 9. It only remains to raise the plate, one side, outside the common plane of it and of the adjacent parts of the bracelet, in order to remove the blocking of said end.
• the movable body 1 * is in 'the form of a bowl which is provided on one of its faces, a peripheral flange 16 the end 17 which is folded towards the center, as is clear from FIG. 3.
• a circular groove 18 which is intended to accommodate the periphery of the plate 2.
• the groove 18 there is a mark 19 which, during the insertion of the plate 2, fits into notch 8 of the last. In this way, the plate 2 and the watch body 1 become integral, the reference 19 and the notch 8 preventing any relative rotation.
• the insertion of the plate 2 in the groove is completed by pressing, using two fingers of the hand, the two ends of the bracelet passing around their bars so that they come closer.
• the two parts 2a, 2b come together in the region of the mouth 4 which reduces the circumference of the plate; it becomes oval and easily penetrates in the groove, its edges 7 crossing the folded end 17 of the edge 16 at a short distance.
• the radial pressure is removed. Thanks to its flexibility, the plate returns to its circular shape and fits securely in the watch body 1.
• the same pressure is used to separate the plate 2 from the watch body 1, the plate again becoming temporarily oval.
• the watch body only its peripheral edge must be adapted to the shape and dimensions of the plate 2.
• the body itself can have any shape, not only circular; it may for example be polygonal or, in a preferred embodiment, have the form of a bottle cap.
• the wafer and the ledge 16 of body- 1 shows should not be necessarily circular quoi ⁇ that this form s ilo preferable from the viewpoint of the invoice manu ⁇ .
