Abstract

Watch comprising at least one case and a strap formed by a flexible blade with a first end fixed to the case and a second opposite end provided to cooperate with a device for attaching and adjusting the length of the strap. According to the invention, the adjustment device comprises a clasp formed by a cap and a lever between which the flexible blade slides, the clasp being hinged on the case by linking means which define an axis of rotation about which the lever can undergo a rotation in order to be able to move into an open position and into a closed position, the lever comprising an eccentric which is integral with the lever in the vicinity of the axis of rotation and is provided in order to clamp the free end of the blade against the cap and to retain the strap when the lever is in the closed position.

First claim

What is claimed is:

1. A watch comprising:
at least one case which includes horns, the horns being positioned at the level of a first side and of a second side opposite the first side;
an adjustment device; and
a strap formed by a flexible blade with a first end fixed to the case and a second opposite end, provided to cooperate with the adjustment device for attaching and adjusting the length of the strap,
wherein the adjustment device includes a clasp formed by a cap and a lever between which the flexible blade is configured to slide, the cap includes two lateral edges extending in a longitudinal direction of the cap, the lateral edges being, disposed in a direction of a length of the flexible blade,
wherein the clasp is hinged on the case by a linking means which define an axis of rotation about which the lever can rotate,
wherein the lever includes a first portion and a second portion, each of the first portion and the second portion rotate about the axis of rotation when the lever is moved into an open position and into a closed position,
wherein the second portion of the lever is comprised of an eccentric in the vicinity of the axis of rotation, the eccentric is integral the lever and the eccentric is closer to the flexible blade than the first portion of the lever is to the flexible blade,
wherein the eccentric is configured to clamp the flexible blade against the cap so that the flexible blade is in contact with each of the eccentric and the cap so as to retain the flexible blade when the lever is in the closed position,
when the lever is in the closed position, the first portion of the lever is adjacent to and extends along a length of the flexible blade such that a gap is provided between the first portion of the lever and the flexible blade so that the first portion of the blade is out of contact with the flexible blade, and
wherein the clasp is hinged between the horns of the watch, the axis of rotation of the lever coincides with the hinging of the clasp between the horns of the watch.

2. The watch according to claim 1 , in which said eccentric comprises a knurling over all or part of its surface.

3. The watch according to claim 1 , in which said eccentric comprises a toothing.

4. The watch according to claim 1 , in which the linking means comprise a lug or a slide.

5. The watch according to claim 1 , in which the clasp is produced in a metallic, plastic, ceramic material or a composite material.

6. The watch according to claim 1 , in which the flexible blade of the strap is made of leather, rubber, textile or a synthetic material.

7. The watch according to claim 1 , wherein a width of the cap is larger than a width of the flexible blade.
