Abstract

A timepiece component having a first part and a removable cap which can adopt a fastening configuration and a free configuration. The first part comprises at least one first latching member and a movable lock. The cap comprises at least one first assembly member designed to cooperate with the first latching member of the first part, and a second assembly member designed to cooperate with the movable lock. In the fastening configuration, the first latching member of the first part and the first assembly member of the cap are in engagement. The movable lock is in engagement with the second assembly member of the cap. The cap is fastened in a locked manner to the first part. In the free configuration, the movable lock occupies an open position in which it releases the second assembly member of the cap and allows the cap to be separated from the first part.

First claim

The invention claimed is:

1 . A timepiece component, comprising:
a first part, and a removable cap, the timepiece component being able to adopt a fastening configuration in which the removable cap is fastened to the first part, and a free configuration in which the cap is separated from the first part, the first part comprising at least a first latching member and a movable lock, and the cap comprising a first assembly member, intended to cooperate with the first latching member of the first part, and a second assembly member, intended to cooperate with the movable lock of the first part, wherein in the fastening configuration of the timepiece component, the first latching member of the first part and the first assembly member of the cap are in engagement, and the movable lock occupies a closed position in which the movable lock is in engagement with the second assembly member of the cap, so that the cap is fastened in a locked manner on the first part, and in the free configuration, the movable lock occupies an open position in which the movable lock releases the second assembly member of the cap, allowing the cap to be separated from the first part, the first part comprises at least one first opening, and the movable lock comprises a lock opening, the at least one first opening and the lock opening being arranged so that they come substantially to face one another when the lock is in the closed position, the timepiece component comprises a retractable bar that is able to cooperate with the at least one first opening and the lock opening when the movable lock is in the closed position, so as to lock the closed position of the movable lock and lock the timepiece component fastening configuration, and so as to be able to release the at least one first opening and lock opening by withdrawing the bar in order to allow the movable lock to move, and pass from the fastening configuration to the free configuration of the timepiece component.

2 . The timepiece component as claimed in claim 1 , wherein the movable lock is mounted on the first part so as to be able to move in translation, in rotation, or both in translation and in rotation.

3 . The timepiece component as claimed in claim 2 , wherein axes of the at least one first opening and the lock opening are offset in the closed position of the lock, so that cooperation between the retractable bar and the at least one first opening and the lock opening, in the closed position of the movable lock, makes it possible to exert a force on the movable lock against the first part of the component, against the second assembly member of the cap, or against both the first part of the component and the second assembly member of the cap.

4 . The timepiece component as claimed in claim 2 , further comprising a play compensating element interposed between the lock and the cap, the play compensating element being made of a material that is flexible, deformable, or both flexible and deformable, the material being designed to be compressed between the cap and the lock when the lock is in the first, closed position, and/or against which the movable lock comes to abut in its first, closed position.

5 . The timepiece component as claimed in claim 1 , wherein axes of the at least one first opening and the lock opening are offset in the closed position of the lock, so that cooperation between the retractable bar and the at least one first opening and the lock opening, in the closed position of the movable lock, makes it possible to exert a force on the movable lock against the first part of the component, against the second assembly member of the cap, or against both the first part of the component and the second assembly member of the cap.

6 . The timepiece component as claimed in claim 5 , further comprising a play compensating element interposed between the lock and the cap, the play compensating element being made of a material that is flexible, deformable, or both flexible and deformable, the material being designed to be compressed between the cap and the lock when the lock is in the first, closed position, and/or against which the movable lock comes to abut in its first, closed position.

7 . The timepiece component as claimed in claim 1 , further comprising a play compensating element interposed between the lock and the cap, the play compensating element being made of a material that is flexible, deformable, or both flexible and deformable, the material being designed to be compressed between the cap and the lock when the lock is in the first, closed position, and/or against which the movable lock comes to abut in its first, closed position.

8 . The timepiece component as claimed in claim 1 , wherein the cap has a form of a substantially planar and elongate element, the first assembly member and the second assembly member of the cap being arranged at the two opposite distal ends of the cap, on a side of the surface of the cap that is intended to be oriented towards the first part of the timepiece component.

9 . The timepiece component as claimed in claim 1 , wherein at least one selected from the group consisting of the first latching member of the first part, the movable lock of the first part, the first assembly member of the cap, and the second assembly member of the cap, has a form of a hook, a notch, or both a hook and a notch.

10 . The timepiece component as claimed in claim 1 , wherein the timepiece is a bracelet clasp cover, and wherein the cap is a substantially planar element that is able to extend over all or part of an upper surface of the cover in the fastening configuration of the timepiece component.

11 . The timepiece component as claimed in claim 1 , wherein the cap has a form of a one-piece element.

12 . The timepiece component as claimed in claim 1 , wherein the cap is made of ceramic, cermet, glass, sapphire, mother-of-pearl, amber or natural or reconstituted stone.

13 . A timepiece, comprising a timepiece component as claimed in claim 1 .

14 . A method for manufacturing a timepiece component as claimed in claim 1 , comprising:
fastening the cap to the first part of the timepiece component, assembling the first assembly member of the cap with the first latching member of the first part, then positioning the cap in a final position thereof provided in the fastening configuration of the timepiece component, then actuating the movable lock of the first part so as to bring the movable lock of the first part into the closed position in cooperation with the second assembly member of the cap, and locking the closed position of the movable lock on the first part using a bar.

15 . The timepiece component as claimed in claim 1 , wherein the timepiece is a bracelet clasp cover, and wherein the first part of the bracelet clasp cover comprises a U-shaped cross section formed by an upper surface from which two opposite and substantially mutually parallel lateral surfaces extend perpendicularly to the upper surface, the upper surface having a planar orthogonal projection that is substantially rectangular in shape, the cap being designed to extend over an entire length of the upper surface of the cover and over all or part of the width of the upper surface of the cover.

16 . The timepiece component as claimed in claim 15 , wherein the first part comprises an upper surface comprising a portion that is set back such that the cap is able to cover the set-back portion of the upper surface in the timepiece component fastening configuration.

17 . The timepiece component as claimed in claim 1 , wherein the tim
