CLASP FOR A BRACELET, IN PARTICULAR OF A WATCH

Abstract

The invention relates a folding buckle clasp for a wristlet allowing different radii of curvature of the clasp when it is in the closed position, said clasp comprising a first blade (1) arranged to rest entirely on the wrist of a wearer of the clasp and a second blade (2) arranged to rest entirely on a wrist of a wearer of the clasp, the first and second blades (1, 2) being articulated with respect to one another at a first end (3), the free end of the first blade (1) having an articulation (4) for articulating a first strand (5) of a wristlet or a third blade (6), the free end (7) of the second blade (2) being arranged to receive a second strand (8) of a wristlet. Each blade (1, 2, 6) is composed separate and interchangeable independent links (10) arranged so as to create a pivoting angle between two successive links (10) of between 20° and 50°.

2. The clasp as claimed in claim 1, the first blade (1) being provided with an elongate recess (11), a second blade (2) and optionally a third blade (6) being articulated and arranged to nest inside the recess (11) along the longitudinal edges (1A, 1B) of the first blade (1).

3. The clasp as claimed in claim 1, each articulated link (10) being connected to an adjacent articulated link via pins or via screws.

4. The clasp as claimed in claim 1, arranged to receive a fixing cap for a wristlet.

5. The clasp claimed claim 1, having a closing/opening system (9) disposed on the first and second blades (1, 2) or on the first, second and third blades to lock said blades (1, 2, 6) or to unlock them so that they can be unfolded.

6. The clasp as claimed in claim 5, having three blades (1, 2, 6), the first blade (1) acting as central support, the second and the third blade (2, 6) being articulated at the respective ends of the first blade (1) and being able to fold down over the latter, the closing and opening means (12) for dosing and opening the clasp being arranged on the central part of the first blade (1) so as to lock the second and third blade (2, 6) against the first blade (1) and to unlock the second and third blade (2, 6) from the first blade (1) so that they can be unfolded.

7. The clasp as claimed in claim 1, having two blades (1, 2), the first blade (1) being arranged to receive a strand of a wristlet and the second blade (2) being arranged to receive a pin buckle.

8. The clasp as claimed in claim 1, the width of each link (10) of the first blade being lower than the width of the second or of the third blade.

9. A wristlet having the clasp as claimed in claim 1.

10. A piece of jewelry having the wristlet as claimed in claim 8.

11. A watch having the wristlet as claimed in claim 8.

Description

[0018] The features of the invention will become more clearly apparent from reading the description of multiple nonlimiting embodiments given solely by way of example, with reference to the schematic figures, in which:

[0019] FIG. 1 shows a perspective view of a clasp with three blades according to the present invention;

[0020] FIG. 2 shows a side view of a clasp with three blades;

[0021] FIG. 3 shows a perspective view of a clasp with two blades; and

[0022] FIG. 4 shows a perspective view of a clasp with two blades.

[0023] As illustrated in FIGS. 1 and 2, an extensible clasp for a wristlet that offers significant flexibility when the clasp is in the closed position, and is intended to be worn by individuals with small wrists, makes it possible to adapt immediately and comfortably to the wearer's wrist. The folding buckle clasp allows the clasp to have different radii of curvature when the clasp is in the closed position. The clasp comprises a first and a second blade 1, 2 articulated with respect to one another at a first end 3. The free end of the first blade 1 has an articulation 4 for articulating a first strand 5 of a third blade 6 at the free end 7 of the second blade 2, which is arranged to receive a second strand 8 of a wristlet. Each blade 1, 2, 6 also has interchangeable and separate, independent articulated links 10 arranged so as to form a pivot angle between two successive links 10 of between 20° et 50°.

[0024] In this example, the clasp has three blades 1, 2, 6, the first blade 1 acting as central support, the second and the third blade 2, 6 being articulated at the respective ends of the first blade 1 and being able to fold down over the latter. Closing and opening means 12 for closing and opening the clasp are arranged on the central part of the first blade 1 so as to lock the second and the third blade 2, 6 against the first blade 1 and to unlock the second and the third blade 2, 6 from the first blade 1 so that they can be unfolded.

[0025] The first blade 1 is provided with an elongate recess 11, the second blade 2 and optionally the third blade 6 being arranged to nest inside the recess 11 along the longitudinal edges 1A, 1B of the first blade 1.

[0026] Each articulated link 10 is connected to an adjacent articulated link via pins or screws, arranged so as to receive a fixing cap for a wristlet. (Not illustrated)

[0027] The clasp has a closing/opening system 9 disposed on the first and second blades 1, 2 or on the first, second and third blades to lock or unlock said blades 1, 2, 6 so that they can be unfolded.

[0028] As illustrated in FIGS. 3 and 4, the clasp has two blades 1, 2, the first blade 1 being arranged to receive a strand of a wristlet and the second blade 2 being arranged to receive a pin buckle.

[0029] The width of each link 10 of the first blade is less than the width of the second or of the third blade.

[0030] Such a clasp may be incorporated in a wristlet, a piece of jewelry or a watch.

[0031] It is entirely conceivable to associate adjustment mechanisms or any other closing/opening mechanism known from the prior art with these types of articulated link clasps.
