Abstract

Clasp comprising a cover connected to a first bracelet strand and to a second bracelet strand, a connecting means being inserted between the second bracelet strand and the cover of the clasp, the connecting means comprising an end link sliding between a first position in which it is engaged in the cover of the clasp, and a second position in which it is outside the cover of the clasp, the end link comprising a push-button which causes a toothed element to change from a first position, in which the toothed element is in mesh with a rack toothing, to a second position, in which the toothed element is released, the end link being provided with an arresting means preventing the removal of the end link from the cover of the clasp, the arresting means comprising at least one lug, which projects into a groove arranged in the bottom of the cover and which defines two end stop members.

First claim

What is claimed is:

1. A clasp for a watch bracelet comprising:
a cover connected on a first side to a first bracelet strand and on a second side to a second bracelet strand,
wherein a connecting means is inserted between the second bracelet strand and the cover of the clasp, the connecting means including an end link configured to slide along a longitudinal direction of the clasp between a first position in which the end link is at least partially engaged in the cover of the clasp, and a second position in which the end link is outside the cover of the clasp,
wherein the end link includes a push-button which, when pressed, causes a toothed element to change from a first position, in which the toothed element is in mesh with a rack toothing, to a second position, in which the toothed element is released from its engagement with the rack toothing,
wherein the end link is provided with an arresting means preventing the removal of the end link from the cover of the clasp, the arresting means including at least one lug that projects into a groove arranged in a bottom surface of the cover, the groove defining two end stop members, and
wherein the end link includes at least one skid which defines a sliding surface between the end link and the bottom surface of the cover.

2. The clasp for a watch bracelet according to claim 1 , wherein a bottom surface of the end link is in contact with the bottom surface of the cover only via the at least one skid that provides a gap between the bottom surface of the end link and the bottom surface of the cover.

3. A clasp for a watch bracelet comprising:
a cover connected on a first side to a first bracelet strand and on a second side to a second bracelet strand,
wherein a connecting means is inserted between the second bracelet strand and the cover of the clasp, the connecting means including an end link configured to slide along a longitudinal direction of the clasp between a first position in which the end link is at least partially engaged in the cover of the clasp, and a second position in which the end link is outside the cover of the clasp,
wherein the end link includes at least one skid projecting from a bottom surface of the end link, the at least one skid being rigidly fixed to the end link and extending along the longitudinal direction of the clasp to define a sliding surface between the end link and a bottom surface of the cover, and
wherein said at least one skid provides a gap between the bottom surface of the end link and the bottom surface of the cover.

4. The clasp for a watch bracelet according to claim 3 , wherein the end link includes at least one lug that projects into a groove arranged in the bottom surface of the cover to prevent the removal of the end link from the cover of the clasp.

5. The clasp for a watch bracelet according to claim 3 , wherein the end link includes a push-button which, when pressed, causes a toothed element to change from a first position, in which the toothed element is in mesh with a rack toothing, to a second position, in which the toothed element is released from its engagement with the rack toothing.

6. The clasp for a watch bracelet according to claim 3 , wherein the at least one skid extends over a fraction of a length of the bottom surface of the end link.

7. The clasp for a watch bracelet according to claim 3 , wherein the end link, including the at least one skid, is made in a single piece.

8. The clasp for a watch bracelet according to claim 3 , wherein the at least one skid includes two skids arranged in parallel to one another.

9. The clasp for a watch bracelet according to claim 3 , wherein the at least one skid extends over an entire length of the bottom surface of the end link.

10. A clasp for a watch bracelet comprising:
a cover connected on a first side to a first bracelet strand and on a second side to a second bracelet strand,
wherein a connecting means is inserted between the second bracelet strand and the cover of the clasp, the connecting means including an end link configured to slide along a longitudinal direction of the clasp between a first position in which the end link is at least partially engaged in the cover of the clasp, and a second position in which the end link is outside the cover of the clasp,
wherein the end link includes at least one skid projecting from a bottom surface of the end link to define a sliding surface between the end link and a bottom surface of the cover,
wherein said at least one skid provides a gap between the bottom surface of the end link and the bottom surface of the cover, and
wherein the end link includes a push-button which, when pressed, causes a toothed element to change from a first position, in which the toothed element is in mesh with a rack toothing, to a second position, in which the toothed element is released from its engagement with the rack toothing.
