Definitions
- the present invention relates to the watchmaking field and concerns, more particularly, a watch wristband or bracelet with articulated links.
- Swiss Patent No. CH 692 234 discloses a wristband having two rows of lateral links and at least one row of central links, connected in an articulated manner by pins.
- the central links include cores made of plastic material intended to reduce friction between the various mobile parts of the wristband.
- the object of the present invention is to provide a wristband formed of metal parts and solid carbon parts avoiding the problems of friction between the two materials while maintaining an excellent aesthetic appearance.
- the invention concerns a watch wristband of the type comprising at least one row of central links, two rows of pairs of lateral links facing each other symmetrically with respect to the longitudinal axis of the wristband in order to connect the central links to each other and a plurality of lugs assembling the central links to the lateral links in an articulated manner.
- This wristband is mainly characterized in that each central link comprises, at least, an external portion including solid carbon and two flanges respectively secured to the faces of the core connected to the lateral links
- each central link comprises a core and a layer of carbon fibre fabric covering said core;
- the core of the central links is made of carbon fibre whereas the flanges are made of metal;
- the central links have the shape of a rectangular plate whose transverse axis is perpendicular to the longitudinal axis of the wristband;
- the lateral links have, overall, the shape of a plate whose transverse axis is parallel to the transverse axis of the central links;
- each lateral link is pierced with three holes parallel to its median plane and to its transverse axis, these holes being arranged such that :
- the lugs are arranged in the three passages of the central links and driven into the holes of the corresponding lateral links;
- the second passage of a central link has a constant diameter, whereas the first and third passages have a slightly greater diameter where they pass through the core;
- the wristband includes two rows of central links and a third row of lateral links inserted between the central links fulfilling, on either side, the same connecting function as the two others.
- FIG. 1 , 2 and 3 illustrate a first embodiment of a wristband according to the invention, respectively in a top, side and exploded view;
- FIG. 4 is a top view of a second embodiment of said wristband.
- the wristband according to the invention includes a row of central links 10 and two rows of lateral links 11 connecting central links 10 to each other in an articulated manner.
- Central links 10 have, overall, the shape of a rectangular plate of oval cross- section. Typically, they have a dimension of approximately 10 mm along longitudinal axis AA of the wristband, a dimension of approximately 14 mm widthwise and a thickness of approximately 4 mm.
- Links 10 are formed of a core 12, preferably made of carbon fibre, covered with a layer 13 of carbon fibre fabric, for example of the Toron type.
- Their oval faces 14, parallel to axis AA, are respectively coupled, advantageously by bonding, to a metal flange 15, for example made of steel.
- the shape of these flanges is identical to that of faces 14 and their thickness is approximately 0.7 mm.
- These elements are mainly used to isolate lateral links 11 from central links 10, in order to protect the latter. Moreover, they contribute to improving the aesthetic appearance of the wristband.
- passages 16, 17 and 18 pass through each central link 10, parallel to its transverse axis DD, in a plane BB parallel to its median plane CC, but slightly offset towards its internal face (i.e. the face applied to the wrist). Passages 16 and 18 are, respectively, in proximity to front and back edges 19 and 20 of the link parallel to its axis DD, whereas intermediate passage 17 is offset on the side of passage 18.
- the front edge of a link is that located closest to the upstream side of the wristband, i.e. the end thereof secured to the watch.
- the back edge of a link is that located closest to the downstream side of the wristband, i.e. the end thereof furthest from the watch.
- passage 16 is at 2.5 mm from front edge 19
- passage 17 is at 3.95 mm from passage 16
- passage 18 is at 2.20 mm from passage 17.
- passage 17 has a constant diameter over its entire passage through link 10, typically 1.25 mm, whereas passages 16 and 18 have a slightly greater diameter where they pass through core 12, typically 1.30 mm, but this is reduced where they pass through flanges 15, typically to 1.25 mm.
- Lateral links 11 are made of metal, for example steel and have, overall, the shape of a plate of oval cross-section having slight concavity towards the wrist.
- longitudinal axis AA of the wristband they have substantially the same dimension as central links 10 but, widthwise and in the direction of its thickness, they have smaller dimensions, namely, typically, 5.1 mm for the width and 3.7 mm for the thickness.
- Each lateral link 11 is pierced, in its median plane FF, by three blind holes 21 , 22 and 23 parallel to its transverse axis GG and to transverse axis DD of links 10. These holes are arranged in the following manner:
- the gap between holes 21 and 22 is the same as the gap between passages 17 and 18 of links 10;
- the gap between holes 22 and 23 is the same as the gap provided between passage 18 of a link 10 and passage 16 of its neighbour.
- All three of holes 21 , 22 and 23 have the same diameter. It is less than the minimum diameter of the passages of link 10 and typically measures 1.15 mm.
- the links of the wristband according to the invention are assembled in the following manner:
- central links 10 allows any dimension and positioning tolerances between cores 12 and flanges 15 to be compensated for.
- central links 10 and lateral links 11 cause lateral links 11 to be lowered towards the inside of the wristband, i.e. towards the arm of the person wearing it. Since it is links 10 that pivot with respect to links 11 , by pressing on the arm, this movement is thus not completely impeded when the wristband is worn, which contributes to making it pleasant for the person wearing it.
- the wristband according to the invention differs to that previously described in that it includes two rows of central links 25 separated by a third row of lateral links 26, placed in longitudinal axis AA of the wristband.
- central links 25 have a smaller dimension than links 10, but, otherwise, they are identical to them.
- Lateral links 26 of the third row are identical to links 11 with which they collaborate, in threes, in order to ensure the articulated connection of the two rows of central links 25.
