Abstract

A one-piece bar is for attaching a bracelet to a watch. The bar extends in a longitudinal direction and includes two pivots and a body connecting the two pivots, each pivot being intended to be introduced into a corresponding housing of a respective horn of a watch case. The body includes a plurality of elements connected to one another, each element having a hollowed portion, in order to give the bar longitudinal elasticity and allow elastic deformation thereof in the longitudinal direction.

First claim

1 . A one-piece bar for attaching a bracelet to a watch, the bar extending in a longitudinal direction and comprising two pivots and a body connecting the two pivots, each pivot being configured to be introduced into a corresponding housing of a respective horn of a watch case, the body comprising a plurality of elements connected to one another, each element having a hollowed portion, in order to give the bar longitudinal elasticity to allow elastic deformation thereof in the longitudinal direction.

2 . The one-piece bar according to claim 1 , wherein the hollowed portion of each element is a substantially central portion of the element.

3 . The one-piece bar according to claim 1 , wherein the hollowed portion of each element is hollowed in a perpendicular direction to the longitudinal direction in which the bar extends.

4 . The one-piece bar according to claim 1 , wherein each element comprises a peripheral frame surrounding the hollowed portion, the peripheral frames of the elements being connected to one another.

5 . The one-piece bar according to claim 4 , wherein the peripheral frame of each element has substantially the shape of a closed ‘M’, the peripheral frames of the elements being connected to one another via longitudinal connecting members, each longitudinal connecting member connecting a portion of frame that closes the ‘M’ of one element to a portion of frame that forms the central acute angle of the ‘M’ of another element.

6 . The one-piece bar according to claim 5 , wherein the body has a first set of elements whose peripheral frame has substantially the shape of a closed ‘M’, and a second set of elements whose peripheral frame has substantially the shape of a closed ‘M’ the number of elements of the first set being equal to the number of elements of the second set, the elements of the first set being oriented in a same first direction along the longitudinal direction in which the bar extends, the elements of the second set being arranged symmetrically to the elements of the first set with respect to a median plane perpendicular to the longitudinal direction, and being oriented in a second direction, opposite to the first direction, along the longitudinal direction.

7 . A wristwatch comprising at least one of the one-piece bar according to claim 1 for attaching the bracelet to the watch.
