Definitions
- the present invention relates to an ultra-thin wristwatch comprising a case-back and a crystal made of plastic, a movement, hands surmounting a dial and a reinforcing metal frame embedded in the case-back and serving among other things as points of attachment to a bracelet.
- Document CH-B-675 339 already proposes a wristwatch, the middle of which can be made of any non-metallic, natural or synthetic material.
- This middle part has a cylindrical housing in which is fixed a housing housing a movement by means of an elastic O-ring engaged, on the one hand, in an annular groove of the cylindrical housing and, on the other hand, in a peripheral groove of the housing .
- the middle part is fitted with a metal frame to which a bracelet is attached.
- the present invention original in that the metallic reinforcing frame serves further platinum on which is fixed at least one central tenon around which pivots a road carrying the minute hand, a barrel wheel carrying the hour hand in turn pivoting on said road.
- the ultra-thin wristwatch has a case-back 7 and a crystal 8 produced in plastic material.
- the watch also includes a movement 9 and hands 10, 11 surmounting a dial 12.
- the watch especially comprises a metal reinforcing frame 13 embedded in the backband 7, this frame serving inter alia as attachment points 14, 15 to a bracelet not shown.
- the present invention is remarkable in that the reinforcing metal frame 13 also serves as a plate on which is fixed at least one central stud 16 whose axis bears the reference 1.
- FIG. 2 shows this frame 13, represented by perspective, before it is molded into the backband 7.
- FIG. 3 shows a carriageway 17 which carries the minute hand 10.
- FIG. 3 shows a wheel 19 with a barrel 20 which carries the hour hand 11.
- the frame 13 in addition to serving to strengthen the case and to attach the bracelet as was known in the prior art, is also used as a plate carrying at least the set of hands indicating the time. This use is new and is not known from previous timepieces.
- the frame or plate 13 carries horns 14 and 15 located at 6 and 12 o'clock arranged to receive in holes 14 'and 15' bars not shown around which will link the strands of a bracelet.
- Figure 2 also shows that the frame 13 has raised edges 21, here diametrically opposite edges. These raised edges pursue two goals, that of first stiffening the frame 13, that then of serving as a support, at least partially, to the dial 12. If we refer to Figures 3, 4 and 6, we see indeed an outer edge 22 of the dial 12 rests on the raised edge 21 of the frame 13.
- the edges 21 and 22 are fixed one to the other. the other, on the one hand to allow the angular positioning of the dial and on the other hand to stiffen the box into a very compact assembly. This edge-to-edge fixing can be carried out for example by means of laser welds.
- the wheel 31 and the pinion 33 form the mobile 2 which is driven by the pinion 34 of a mobile 6 which further comprises a wheel 35 itself driven by the pinion of a motor mobile 5 comprising a magnetized rotor 37.
- the mobiles 5 and 6 comprise pivots rotating in bearings made on the one hand in the plastic material of the bottom 7 and on the other hand in a bridge 38.
- the lower bearing consists of a bore 39 made in a plug 40 filling an opening 41 of the frame 13.
- the plug 40 is obtained during injecting the bottom 7.
- the movable motor 5 is pivoted in the same way as the movable 6 by means of a plug 51.
- the magnet 37 is surrounded by a stator 42 linked to a core 43 on which a coil 44 is wound.
- Two other pins are fixed to the frame 13 as seen in Figures 2 and 6. This is the pin 45 on which rotates the mobile 4 composed of a pinion 46 and a wheel 47.
- the pinion 46 is driven by the sliding pinion 48 when the rod 49 is pulled for setting the time of the watch. It is also a tenon 50 on which the mobile 3 turns which drives the wheel 31 already mentioned.
- These two studs are directly fixed to the frame, in the same way as are the studs 30 and 50 already described.
- the frame or plate 13 is used, in the embodiment taken as an example, to support not only the central mobile 1, but other mobile either by means of tenons 30, 45, 50, or by means of bearings made in plugs 40 and 51 molded in holes in the plate 13.
- the backband 7 and the crystal 8 are made of heat-sealable thermoplastic materials.
- the middle part 7 is made of a material chosen from the group comprising acryl butadiene styrene (ABS) and the crystal is made of a transparent acrylic resin (PMMA).
- Means are provided for assembling the crystal 8 and the middle part 7, these means comprising a localized zone 23 constituted by a mixture of said heat-sealable materials together (see FIGS. 4, 5 and 6).
- the interested reader will profitably read a description of this technique in document EP-B-0 101 663 (US-A-4 558 957). It is therefore not necessary to expand here further on this process.
- the bowl-shaped dial pursues two goals: firstly to make it more rigid and secondly to provide thick components of the watch under its peripheral zone, namely the motor elements ( Figures 4 and 5) , the time-setting mechanism (FIG. 6) and the battery, the location of which can be seen in FIG. 2.
- the motor elements Figures 4 and 5
- the time-setting mechanism FIG. 6
- the battery the location of which can be seen in FIG. 2.
- a dial in the form of a bowl has been described in the document CH-B-620 081.
