Definitions

• the object of the present invention is to adapt very different materials in the design and decoration of watch cases. Indeed the fashion trend wants that the middle of the watch is sometimes designed in a material incompatible with the conventional means of manufacture and the requirements of machining tolerances such as crystal, wood, stone, carbon, sapphire, or any other material giving luster to the watch. Such achievements are real technical prowess which justifies the price of these objects with high added value.
• the invention therefore consists in using such materials, but they are only the external decoration giving the illusion that the boitter is a unique piece.
• This makes it possible to mold to cut, to mill, to grind, to drill, to polish by conventional means this material in a geometry compatible with manufacturing in very large series and to support deviations in dimensions which have nothing to do with the manufacture of a watch case.
• the adornment thus produced envelops the middle of the watch, giving it its final appearance.
• the purpose of the present invention is to provide a device for mounting a set on a watch middle part and which makes it possible to absorb the manufacturing tolerances inherent in decorative pieces. This device must allow easy assembly of the assembly and a cost compatible with mass production.
• the object is achieved by a device according to claim 1.
• the mechanical connection between adornment and middle is ensured by an elastic device with two elastic means absorbing shocks and variations in dimensions.
• This device makes it possible to combine shock absorption, differences in dimensions and obtain a very good seal.
• the back of the watch is used as a support for the adornment and tightening it keeps the adornment in place between the two elastic means.
• These means can have many forms, whether L-shaped or tubular, see flat. Thanks to these two elastic means, the set is never clamped against a rigid surface.
• Figure 1 shows a half-section at 12 o'clock of the watch showing the originality of the invention.
• Figure 2 shows a detail of the lower corner of the set and the flat seal housed under the middle.
• Figure 3 shows a sectional view of the mounting of the base on the middle.
• Figure 4 shows a top view of the watch with its adornment.
• Figure 5 shows a section through the assembly of the winding stem.
• Figure 1 we can distinguish the caliber (1) (movement), the casing circle (2) positioning the caliber, the glass (3), the middle (4), the adornment (5), bracelet support (6) the fixing screw (7), the bottom (8).
• Figure 3 shows us a partial section at 8 hours of the elastic connection formed by the seal (9) surrounding the outside of the middle (4) positioned in its groove and the flat seal (10) occupying the entire surface of the watch leaving the passage for the fixing screws (11).
• the assembly of the winding stem (12) is illustrated.
• the seal (14), ensuring the seal between the middle part (4) and the crown stem (12) is mounted in a stage housing disposed at the entrance to the orifice intended to receive the winding stem .
• the winding stem has a groove in which an o-ring (15) is placed, this groove being located along the passage of the stem in the orifice of the middle part.
• the longitudinal movements of the rod move the seal (15) along the orifice of the middle while ensuring the tightness of the watch.
• the crown (13) allows the time setting and the other functions that the caliber allows.
• Figure 4 shows us the set (5) installed on the watch. It is obvious that the shapes presented in this drawing are only examples and that other shapes can be used as long as the set is suspended by the principle of the invention.
• the present invention extends to other embodiments such as the replacement of the flat seal 10 by an o-ring seal similar to that placed in the groove of the middle part and exerting an oblique force on the adornment.
