a clasp 2 with folding blades comprises two blades 2a, 2b, articulated to one another about an axis 3.
One of these blades, the blade 2a is articulated at a first end 1a of a 1 bracelet, while the second end 1b of this bracelet is articulated to a cover 24 of the clasp provided with two parallel side walls 2c1, 2c2, forming a cover under which the blades 2a, 2b, fold.
the two parallel side walls 2c1, 2c2, of this cover 24 comprise two series of respective bores 4 which face each other in pairs, intended to receive a pivot axis, as will be detailed below.
the guiding and fastening system 10 belonging to the first embodiment of the invention is arranged at the second end 1b of the bracelet, about an axis A1, as will be detailed in more detail.
This guide and hooking system first forms a hinge axis for adjustment meshes 23, 23 'arranged under the cover 24 of the clasp.
These same adjustment meshes 23, 23 ' are linked by a second pivot axis 26, arranged around a second axis A2, in particular visible on the figure 2 , distinct from the axis A1 of the guiding and fastening system 10, around which is mounted rotatably an end mesh 25 has the end 1b of the bracelet 1.
the figure 3 illustrates the same arrangement during actuation, in particular to go from the long configuration to the short configuration.

This spring tube 15 forms a hooking device of the guiding and hooking system 10, which fulfills the second function of elastic hooking.
at least a portion of the spring tube 15 is provided to be compressed under the actuation of the end mesh 25, more particularly under the actuation of a notch 22 of this end mesh 25, according to this mode. embodiment, in short configuration of the bracelet.
This compression of the tube causes its elastic deformation of its peripheral wall in a direction substantially perpendicular to the axis A1, thus in the direction of the bar 12.
This cooperation with the end mesh 25 ensures the attachment of this end mesh And stably maintaining the entire arrangement in a short configuration. Voluntary traction of this end mesh 25 with a force predetermined, allows him to escape its elastic attachment and return to the long configuration of the bracelet.
the connection between the spring tube 15 and the bar 12 of the guide and hooking system 10 is such that the spring tube 15 is independent of the bar 12 and vice versa.

the spring tube 15 is arranged and dimensioned so that the inner diameter of the spring tube 15, once compressed, does not collide with the outer periphery of the bar 12. Its elastic deformation is free, and n ' has no impact on the bar 12, and does not impair its guiding function. Conversely, the bar 12 has no influence on the elastic function of the spring tube 15 in its guiding operation.
the two guiding and hooking devices of the guiding and fastening system 10 are combined with each other so as to form a compact device, of minimal size, and which does not detract from the aesthetics of the clasp or the clasp. bracelet. They also allow to be assembled and integrated easily within the bracelet.
the two devices respectively for guiding and hooking of the guiding and hooking system are independent of each other.
the elastic attachment function is based on an elastic deformation of at least one spring component of the guide and fastening system, independently of the guide portion, that is to say that this deformation n has no impact on the components of the first device participating in the guidance function.
the holding force is defined solely by the elastic deformation of the spring tube 15, without risk of plastic deformation of the bar 12, nor risk of bending of the bar 12.
the holding force is also independent of the mesh material 25 end, including the material of the notch 22 of the end mesh 25, which comes directly cooperate with the spring tube 15 during the implementation of the attachment of the mesh 25 by the spring tube 15.
the elements 120, 13, 13 'of the guide bar 12 may be in a 904L steel or gold type material.
the spring tube 15 can be in a Nivaflex® type spring material, or alternatively a superelastic nickel and titanium alloy such as Nitinol.
the geometry of the tube can of course be adapted to optimize its mechanical characteristics.

FIGS. 6 to 9 illustrate a system for guiding and hooking up a length adjustment device according to a second embodiment of the invention.
This device is likewise integrated in a cover 24 of clasp and participates in a length adjustment of the bracelet.
This setting differs from the solution described with reference to the first embodiment, in particular in that the guiding and fastening system 10 belonging to the first embodiment is movable in longitudinal grooves or rails 6 arranged in the vertical walls 2c1. 2c2 of the cover 24.
the figures 6 and 7 illustrate the arrangement in short configuration of the bracelet. Adjustment meshes 23, 23 'are positioned so that the second pivot axis 26 is oriented towards the inside of the cover 24 of the clasp relative to the first axis A1.
the end mesh 25 of the bracelet and the pivot axis 26 are thus in the retracted position facing the end 1b of the bracelet.
the end mesh 25 comprises a finger 28 cooperating with a toothing 8 arranged in the bottom 240 of the cover, to block the displacement, substantially corresponding to a translational movement, of the length adjustment device. of the bracelet.
the teeth of this toothing 8 define several positions of the end mesh 25 of the bracelet opposite the cover 24 of the clasp and therefore several lengths of the bracelet.
the finger 28 cooperates with the first tooth of the toothing 8 from the inside of the cover 24, which corresponds to the shortest position of the bracelet.
the figure 8 illustrates the adjustment device being actuated to make a length adjustment.
the end mesh 25 of the bracelet is manually turned about its pivot axis 26 arranged between the adjustment meshes 23, 23 ', with a predetermined force allowing the to release from its elastic hooking in the hooking device of the guide and hooking system, while releasing his finger 28 of the toothing 8 of the lid of the clasp.
the adjustment device is thus free to move longitudinally in the lateral grooves of the clasp.
the end mesh 25 is folded towards the bottom 240 of the lid, so that it comes to catch elastically in the attachment device of the guiding and fastening system 10 , while blocking its longitudinal position by the positioning of its finger 28 in a new tooth of the toothing 8 of the clasp.
the guiding and fastening system 10 is more particularly illustrated by the cross section of the figure 9 .

a spring tube 15 is disposed coaxially with the bar 12, similarly to the first embodiment.
the mesh 25 may also comprise a notch 22 whose conformation is provided to generate adequate compression forces of the spring tube 15.
the connection between the spring tube 15 and the bar 12 of the guiding and hooking system 10 is such that the spring tube 15 is independent of the bar 12 and vice versa.
the spring tube 15 has, at each of its ends, a portion 16, 16 'provided with a surface of guide, which is provided to cooperate with a complementary surface for guiding the adjustment meshes 23, 23 ', implemented for example by a bore 230, 230' of these meshes.
the spring tube 15 is arranged and dimensioned so that the internal diameter of the spring tube 15, once compressed, does not collide with the outer periphery of the bar 12. Its elastic deformation is free, has no no impact on the bar 12, and does not impair its guiding function. Conversely, the bar 12 has no influence on the elastic function of the spring tube 15 in its guiding operation.
the guide of the tube is withdrawn by means of the adjusting meshes 23, 23 'with a defined clearance so that the spring tube 15 can be rotated or not under the effect of the notch, before and / or during the compression of the spring tube 15.
the Figures 10 to 14 illustrate a guiding and latching system 30 belonging to a third embodiment of the length adjustment device, which is similar to that shown in FIG. figure 1 .

the two guiding and hooking functions are thus provided independently of each other.
the hooking function is also independent of the mesh used, in particular the material used for the links of the bracelet.
the holding force is defined solely by the elastic deformation of the springs 35, without risk of plastic deformation of the notches or notches, or risk of bending of the bar 12.
the bar 32 is substantially cylindrical, about an axis A1, and provides guidance in rotation of a control mesh 23 about this axis A1.

the balls 45, 45 'of the guiding and fastening systems 30, 30' can be replaced by studs or any other component whose geometry is adapted to form an adequate interface between a spring and a notch: we will use therefore the term ball in the broad sense, to include geometries not necessarily spherical.
the Figures 15 to 18 illustrate a guiding and latching system 40 belonging to a fourth embodiment of the device for adjusting the length of a bracelet within a clasp.
Such a guiding and hanging system comprises a bar 42 forming a hollow axis. A part of its outer periphery 43 is intended to guide an adjusting mesh 23.

the balls 45, 45 'of the guiding and fastening systems 30, 30' can be replaced by studs or any other component whose geometry is adapted to form an adequate interface between a spring and a notch: we will use therefore the term ball in the broad sense, to include geometries not necessarily spherical.
the invention is therefore based on the optimal arrangement of an elastic coupling device, in combination with a guiding device, to obtain a compact assembly allowing the definition of performance and improved aesthetic results.
This combination of two guiding and hooking devices is advantageously around a single axis, which may be an axis of symmetry and / or an axis of rotation during the implementation of a guiding function.

guiding device a device provided with at least one means, including a surface, for guiding a component relative to a separate component.
This guidance may be a rotation and / or a displacement in a groove, in particular a displacement substantially corresponding to a translation or displacement corresponding to the curvature of a clasp cover. It can be implemented with a bracelet mesh, in particular an adjustment mesh, and / or a clasp.
the two guiding and hooking devices are independent, that is to say that they implement their respective functions without influence on the other device.
one or two guiding and latching systems have been used with two adjustment meshes: alternatively, a different number of guiding and latching systems could be used, as well as a different number of meshes of adjustment .
the guiding surfaces taking part in the guiding systems could also be substituted by guiding means taking for example the form of several edges.
the guidance and attachment system is associated with a device for adjusting the length of a bracelet within a clasp, as described above.
a control mesh and possibly at least a portion of an end mesh is located under a lid formed by the clasp, this mechanism thus remaining hidden.
the clasp can be of different types, with two or three folding blades.
