Detailed Description
A device for adjusting the length of a band in a clasp according to an embodiment of the invention will now be described.
This device for adjusting the length of the bracelet comprises two lateral

The rod 3 comprises an annular central portion 33 in which a spring 34 is arranged, which spring 34 exerts an elastic thrust on the cylindrical receiving element 4 at the end of the rod 3 and indirectly on the
In this embodiment, the first guide element 10 (i.e. the slider or the roller or the ball) is one-piece. Furthermore, they are entirely composed of high-performance polymers belonging to the family of Polyaryletherketones (PAEKs), in particular Polyetheretherketones (PEEK).
The applicant's studies have shown that such polymers have the advantage of optimizing the reliability and durability of the parts, in particular by better wear and scratch resistance. In particular, the properties are particularly superior to those of polyacetal-based polymers in terms of slidability and durability.
Alternatively, the

For example, a watch clasp cover has runners provided in side walls formed in both sides of the cover. In this particular case, the cover is one-piece. It may be composed entirely of high-performance polymers, in particular of PEEK. Alternatively, the slide may be coated on all or part of its surface only with a polymeric material belonging to the family of Polyaryletherketones (PAEKs), in particular PEEK. As a further alternative, the cover may be made entirely of another material, such as metal.
In the family of Polyaryletherketones (PAEKs), the material selected may be filled or unfilled. The filler may in particular optimize the friction and mechanical properties of the component. For example, the filler may comprise at least reinforcing fibres and/or a lubricant and/or graphite. As a variant, the filler may also comprise at least one pigment, in particular for the purpose of coloring the part.
According to an exemplary embodiment, the material selected will be PEAK, in particular PEEK, Polyetheretherketone (PEEEK), Polyetherketone (PEK), Polyetherketoneketone (PEKK) or a copolymer and/or polymer mixture thereof. Furthermore, the polymeric material may advantageously comprise at least one filler of Polytetrafluoroethylene (PTFE), molybdenum sulphide, tungsten disulphide, hexagonal boron nitride, carbon fibres, aramid fibres, glass fibres, graphite, graphene, carbon nanotubes, polyimide, polyphenylene sulphide, diamond nanoparticles, polysilsesquioxane, boron fibres or a combination of two or more thereof. The above list is of course not limiting.
According to certain exemplary embodiments, the material is a material containing 20% PTFE of PEEK, e.g. of450FE 20. According to another embodiment, the material is PEEK containing 30% of additives, in particular carbon fibers and/or graphite and/or PTFE. According to another embodiment, the material is PEEK containing 30% carbon fibers and additional additives, in particular graphite and/or PTFE. Alternatively or in addition to the carbon fibers, the fibers contained in PEEK may be aramid fibers or boron fibers. Examples of PEAK or PEEK that may be used are, inter alia:PEEK 450FC30、HPV、
PVX、KT-820SL30、PEAK CF30、AV-651CF30、AV-722SL30、AV-755SL 45. It should be noted that in all cases, in particular in all the embodiments described, the PEEK polymer may be replaced by any other polymer of the PEAK family.According to a particular exemplary embodiment, the component comprises 65% PEEK, 15% carbon fiber, 10% PTFE, 8% carbon nanotubes, and 2% nanodiamonds.
The element or part of the element made of a material belonging to the family of Polyaryletherketones (PAEK) is manufactured by any method or combination of methods known to the person skilled in the art. According to a variant embodiment, the surface of the part or of the part made of a material belonging to the family of Polyaryletherketones (PAEK) may be structured, in particular microstructured, in particular for shaping the first element, in order to further optimize the friction and/or wear properties of the surface made of PEAK, or to better distribute the lubricant. Such structuring can be obtained directly during the shaping of the part or subsequently by machining or micromachining, for example by means of laser surface structuring (or LST) or chemical etching. Any other technique or combination of techniques may also be implemented to achieve structuring or microstructuring.
According to a particular embodiment of the invention, it has been seen that the guide element or a portion of the guide element, which may be a portion made of a polymer or metal, is at least partially coated with a coating comprising a material belonging to the family of Polyaryletherketones (PAEK), in particular PEEK. In such embodiments, the coating may be applied by using conventional dispersion spray techniques, electrostatic spray techniques, or overmolding. It is also possible to apply a coating to the surface microstructured element according to one of the preceding embodiments, with or without the component: such as a DLC coating or any other suitable coating technique. The microstructuring of the surface can also be carried out after the application of the coating.
In addition, according to this embodiment, the relative displacement of the

Alternatively, the indexing element 15 may be realized by the cylindrical receiving element 4 of the rod 3, in particular by the end of the cylindrical receiving element 4 of the rod 3, as shown in fig. 9. For this purpose, the cylindrical receiving element 4 passes directly through the
It should be noted that the indexing means described above can be combined with complementary indexing means of the links of the bracelet with respect to the clasp cover, that is to say it can complement a conventional indexing system, such as a lever indexing system or a ball indexing system, which in particular implements the tooth 35' shown in fig. 1 and 2. Such a conventional indexing device in fact fulfils the function of a fastening device displaceable in the longitudinal direction of the clasp for the adjustment assembly of the device for adjusting the length of the bracelet. Thus, such a fastening device, which can be displaced, can produce different bracelet lengths. Such fastening means may therefore comprise a
The invention therefore also relates to a bracelet lengthening device comprising a link with a
It is noted that the recess forming the second indexing element complements a recess known in the art, such as the recess 35' forming the fastening means, which is visible in particular in fig. 2. The indexing means can thus form a predetermined bit element which assists the user in making the adjustment by achieving a suitable position of the adjustment assembly, in particular suitably acting on the fastening means. Such indexing means are insufficient to secure the adjustment assembly which can be easily disengaged from the different recesses to allow adjustment. It does not perform the fastening function. As previously mentioned, it is supplemented with different fastening means.
The indexing element may form a one-piece assembly with the guide element or a different element disposed adjacent to or through the guide element. Furthermore, the indexing element may take the form of an assembly, for example a ball ratchet comprising balls resiliently returned by springs, the latter being able in particular to supplement or replace the springs 34 of the rod 3, in particular shown in fig. 3.
Note that according to this embodiment, the spring 34 cooperates with the first indexing element 15 to exert a resilient thrust on the first indexing element 15 towards the
These indexing elements behave in a manner that is very similar to the stress to which the guide elements are subjected. They may therefore also advantageously comprise polymeric materials belonging to the family of Polyaryletherketones (PAEKs). Additionally or alternatively, they may comprise other materials.
As a variant, the first diversion element 15 can be realized separately from the
The invention therefore also relates to a watchband extension device comprising at least one link connected to a clasp cover, the link comprising a first indexing element 15 and the
When adjusting the length of the bracelet, the user rotates the
The invention also relates to a bracelet and/or clasp and/or watch incorporating the aforementioned bracelet lengthening device.
