Embodiment Construction

[0036] For brevity, the instructions will use the term "longitudinal" in the plane of the strap (across its width) or buckle by convention to mean the direction along the length of the strap or buckle, and "transverse" to mean vertical direction. A vertical direction is a direction perpendicular to the first two directions, oriented perpendicular to the plane of the bracelet. Furthermore, the term "link elements" will be used for the basic constituent parts of a watch chain, and the term "links" will be used for a collection of link elements. "bracelet" will be used to mean a watch chain as a whole, or a strap or other straps of a watch chain, with or without a clasp. Furthermore, the same reference numerals will be used in various embodiments to designate the same or similar elements or elements providing the same function.

[0037] The present invention relies on a combined guiding and fastening system. The guide and fastening system of the length adjusting device accordi...

Abstract

A device for adjusting the length of a bracelet comprises a guidance and fastening system (10, 30, 40, 50), including at least one adjusting link element (23) mounted with the ability to rotate aboutan axis of rotation (Al) defined by a guidance device of the guidance and fastening system. The guidance and fastening system (10, 30, 40, 50) includes an elastic fastening device comprising an elastic property in order to perform an elastic fastening function. The two guidance and elastic fastening devices are arranged around the axis (A1), notably upon implementation of the fastening function. The elastic fastening device provides elastic immobilization of an end link element (25) connected to the adjusting link element (23), particularly relative elastic immobilization of the said end linkelement (25) with respect to the adjusting link element (23), or of the adjusting link element (23), in at least one configuration of the adjustment device.

Description

technical field [0001] The invention relates to a device for adjusting the length of a watch chain, comprising a specific guide and fastening system for the watch chain, which is especially adapted to be provided with extension means installed between the two ends of the watch chain and / or unfold the clasp watch chain. The invention also relates to the buckle of such a length-adjusting device enclosing a watch chain and to the watch chain itself, as well as to the watch itself comprising such a device. Background technique [0002] There are several situations in which it is necessary to perform a guiding and fastening function on a bracelet, especially a watch, in particular in a device for adjusting the length of the bracelet. [0003] For example, a clasp designed to secure the two straps of the bracelet around the wrist of the wearer of the bracelet includes several hinged leaves capable of occupying a first closed position and a second open position, wherein, in the cl...
