[0014] To simplify the description of the invention, corresponding or identical elements in different variant embodiments are provided with the same reference numbers.

[0015] The invention is therefore based on a device for fastening a wristband to a small watch body, and more generally to a small watch case, said fastening device comprising two complementary main elements, a connecting element and a receiving element, arranged respectively on the wristband and on the small watch case, or vice versa, the connecting and receiving elements being intended to be releasably fastened to each other, as will be explained below.

[0016] 1 to 3 show an embodiment of the invention in which the connecting element 11 takes the form of a wristband link forming a connecting link intended to be placed at the end of a wristband 10. The connecting link advantageously has the same shape and has the same appearance as the other wristband links.

[0017] In this embodiment, the fastening device further comprises a receiving element 21 in the form of two substantially parallel protrusions arranged oppositely on the body 20. Each protrusion comprises a hole 21a, in particular in the form of a blind hole. The respective holes 21a of the two protrusions are arranged along axes, which are preferably substantially aligned. The holes preferably have a circular cross section. The openings of the two holes are directed towards each other. The space between the two protrusions defines a housing, which the connecting link of the wristband is intended to occupy. The visible outer surface of the protrusions is not modified in any way, without discontinuities that could deteriorate its appearance. Nevertheless, as an alternative, the two holes may be through holes and / or may be provided with bearing surfaces and / or may have an orientation that is not parallel to each other.

[0018] The fixing device further comprises two pins 1 intended to fix or not fix the connecting element 11 to the receiving element 21. Each pin 1 can occupy two positions, as described below: a position protruding from the connecting element 11 as shown in Figure 2, and a position retracted into the housing 11a of the connecting element 11 as shown in Figure 3.

[0019] For this reason, the fixing device is - a first configuration in which pin 1 occupies a retracted position within the connecting element, allowing the wristband link to be separated from the watch case; a second configuration in which the pins 1 are held in a position protruding from the connecting element 11 and positioned in respective holes 21a of the receiving element 21 so as to fix the connecting element 11 and the receiving element 21 therebetween and to connect the wristband to the watch case; The device is designed to have at least two configurations:

[0020] Each pin 1 is positioned in a housing 11a of the connecting element 11. The two housings 11a preferably extend along the same axis A1. Furthermore, the housings 11a take the form of a transverse through hole, which thus opens into two opposite walls or sides 11b of the connecting element. Each housing 11a allows the pin 1 to slide freely along the axis A1 with one degree of freedom of movement in translation, which allows the pin 1 to be positioned to protrude from or retract into the side 11b of the connecting element 11, respectively, to allow the assembly and removal of the connecting element 11. Alternatively, each of the housings 11a may take the form of a blind hole opening into the side 11b and / or be provided with a bearing surface.

[0021] The connecting element 11 further comprises a recess 2a, extending from the wall of the connecting element 11 and opening into at least a part of the housing 11a of the pin, so as to allow the operator to manipulate the pin 1 in the recess 2a. In this embodiment, a mounting element 2, taking the form of a cover, is intended to be placed in the recess 2a. When positioned in said recess, the mounting element 2 cooperates with the pin 1, as will be described below. A fastening element 4, such as a screw, allows the mounting element 2 to be fixed in the housing 2a of the connecting element 11. To this end, the connecting element 11 comprises an internal thread 4a. The mounting element 2 is preferably removable. Furthermore, the mounting element 2 advantageously has a shape complementary to the shape of the recess 2a, in particular a volume corresponding or substantially corresponding to the volume of the recess 2a, so that when the mounting element is fixed to the connecting element 11, its visible surface merges with the adjacent surfaces of the connecting element 11 and / or the receiving element 21, so as to form a substantially continuous surface. Due to this arrangement, the attachment element 2 may be integrated with the fastening device and optimize the aesthetic appearance of the connection element 11 and / or the receiving element 21. In addition, the attachment element 2 is preferably arranged on the invisible side of the connection element 11. For example, the attachment element is provided on the face of the connection link that is intended to come into contact with the wearer's wrist. Alternatively, the attachment element may take other shapes and in particular protrude from the connection element 11 and / or the receiving element 21. As a further variant, the attachment element may be fixed to the connection element by other means, such as hammering, gluing, clipping, welding, brazing, etc. For this reason, the attachment element does not have to be detachable, in which case the wristband is not detachable once it has been fastened to the torso. In other variants, as will be explained below, the attachment element may consist of several parts and / or be arranged in the receiving element 21. For this reason, the recess 2a may also consist of several parts and / or be arranged in at least a part of the housing 21a of the pin of the receiving element 21. Of course, the fastening means of the mounting element or elements will have to be adapted and / or repositioned on the receiving element.

[0022] In this embodiment, each pin 1 has a completely identical shape and is arranged in a symmetrical manner on the connecting element 11, which has a shape that is substantially symmetrical with respect to a median plane perpendicular to the axis A1. Each pin 1 has a cylindrical central part, a first functional part that is oriented towards the outside of the connecting element 11 and has a cylindrical shape, and a second functional part that is oriented towards the inside of the connecting element 11 and has a number of functional surfaces. The first and second parts of each pin 1 are arranged on opposite sides of the central part. Each pin 1 is translationally movable in the housing 11a of the connecting element so that at least a first part protrudes from a side surface 11b of the connecting element and can occupy a protruding position so that it can be arranged in a hole 21a of the receiving element 21. In this way, the first part is intended to form a pivot 1a around which the receiving element 21 is rotationally movable relative to the connecting element 11.

[0023] Each pin 1 further comprises a functional surface in a second part opposite the first part. In particular, a first inner end of the second part of each pin 1 forms an abutment surface or stop 1b. The mounting element 2 comprises at least one first surface defining a first axial abutment or stop 2b intended to cooperate with said abutment surface 1b of each pin 1 in order to hold the pin in a position protruding from the side surface 11b of the connecting element 11 when the mounting element 2 is fixed to the connecting element 11. In other words, when the mounting element 2 is fixed to the connecting element 11, its first surface engages with the abutment surface 1b of the respective pin 1 in the protruding position, thereby preventing the pin 1 from moving back from the side surface 11b of the connecting element 11, so that the pin 1 continues to protrude.

[0024] In addition, the second part of each pin 1 comprises a non-cylindrical part 1c, which is intended to cooperate with a complementary part 3 of the attachment part 2, visible in FIG. 2, in order to prevent any rotation of the pin 1 around the axis A1 in the presence of the attachment element 2. In the illustrated embodiment, the non-cylindrical part 1c of the pin 1 has a triangular cross-section formed by three surfaces 1d, one or the other of which forms a second abutment 3, which is intended to cooperate with the complementary part 3 of the attachment element 2, thus preventing a respective rotation of the pin 1. Thus, the rotating second abutment 3 of the attachment element 2 allows for a rotational immobilization of each pin 1 with respect to the connecting element 11. Alternatively, the non-cylindrical part 1c may have, for example, a square, three lobe or half-moon cross-section. Alternatively, the rotating second abutment 3 of the pin 1 may be arranged on the connecting element 11, and not on the attachment element 2. In this kind of variant, the rotating second abutment of the connecting element may cooperate with the pin 1 only in its extended position, or alternatively also in its retracted position. In a further variant, the rotating second abutment 3 of the pin 1 may be arranged in the hole 21a so as to cooperate with the pin 1 only in its projecting position. Furthermore, the various functional parts of the pin 1 may be arranged in any other manner that allows a fixing according to the invention. For example, in another design variant, the abutment surface 1b may be in the same part as the pivot 1a, opposite to the other part where the non-cylindrical part 1c is located. Of course, this example does not limit the invention. Some of the possible variants are specified below.

[0025] To sum up, in the embodiment in question, in the absence of the mounting element 2, each pin 1 has two degrees of freedom of movement relative to the connecting element 11: translation along the axis A1 and rotation about the same axis A1. Fixing the mounting element in the position in which the pin 1 projects from the connecting element 11 makes it possible to remove these two degrees of freedom of movement, so that the pin 1 remains immobilized in its projecting position and can no longer rotate within the housing 11a of the connecting element 11.

[0026] The operation of the fixing device according to an embodiment of the invention is described below. When the device is in the fixed configuration, as shown in FIG. 2, the craftsman can remove the attachment element 2 by unscrewing the screw 4. This allows the craftsman to access the recess 2a of the connecting element and the second functional parts of the two pins 1, which are at least partially arranged in said recess. The craftsman can then move the pins so that they move in translation in the recess 2a from their extended position to their retracted position. To aid this operation, each pin 1 preferably comprises, at the height of said second functional part, a notch or groove 1f that allows the insertion of a simple tool, such as a pin or tweezers, to manually guide the translational retraction movement of the two pins. Of course, any other means or tools that allow the actuation of the two pins are also envisaged, for example a magnet. Once the operation is completed, the first functional part of each pin 1, in particular its pivot 1a, is housed in the connecting element 11 and is free from the hole 21a of the receiving element 21. The connecting element 11 can then be removed from the receiving element 21. The reverse operation allows the two elements to be secured together.

[0027] In order to reduce the frictional wear surfaces of the articulation relative to the connecting and receiving elements, the pin 1 and / or the receiving surface of the receiving element 21 which receives the pin 1 and / or the receiving surface of the connecting element 11 may preferably be made of a material which limits frictional wear, such as a sintered ceramic, advantageously based on zirconia.

[0028] Alternatively, according to the embodiment, in order to obtain the required aesthetic finish, it is necessary that the body including the projections and the receiving element 21 and / or the connecting element 11 can be manufactured from metal, in particular from a precious metal such as gold or platinum. Similarly, the pin may also be made from steel or a precious metal. Of course, other materials are also envisaged, such as composite materials.

[0029] According to an advantageous embodiment, the invention uses an insert 5 which forms a contact surface at the friction surface of the fastening device. In the described embodiment, the friction surface is arranged at the contact surface between the pivot 1a formed in the first part of the pin 1 and the hole 21a of the receiving element. In that embodiment, the insert 5 preferably takes the form of a tube or a bearing. The insert may or may not be fixed in the hole 21a. Alternatively, the insert may or may not be fixed to the first functional part of the pin 1. In another variant design, the friction surface may be arranged at the contact surface between the housing 11a and the pin 1, for example between the pivot 1a and the housing 11a of the connecting element. In that variant, the insert may optionally be fixed in the housing 11a. Alternatively, the insert may optionally be fixed to the pin 1 in the area where it (frictionally) slides with the housing 11a.

[0030] The insert may advantageously be made of sintered ceramic or a composite material, for example formed from a mixture of ceramic and metal, or a (for example thermoplastic) polymer. The insert may be completely or partly manufactured from such a material. For example, such a material may form a simple coating. The insert 5 advantageously has a hardness of 800 HV or more.

[0031] Furthermore, in the described embodiment, the pivot 1a formed in the first part of the pin 1 includes a bearing surface defining an axial abutment 1e between the pivot and the insert 5 in order to prevent contact, and consequently wear, between the side surface 11b of the connecting element 11 and the side wall 21b of the receiving element 21.

[0032] Of course, the invention is not limited to the exact shapes of the various elements described. Thus, the bearing 1a of the pin 1 may have other shapes that allow the articulation of the two elements of the fixed element. For example, the pivot 1a may be conical or frusto-conical. Of course, the shape of the insert 5 may be suitably adapted and complementary to the shape of the pin.

[0033] In the described embodiment, the pin is preferably constrained to rotate with the connecting element 11 such that the frictional surface of the articulation is localized at the contact point between the pin 1 and the hole 21a of the receiving element, and more specifically between the pin 1 and the insert 5. Of course, the reverse is also possible, and the pin may be constrained to rotate with the receiving element 21 such that the frictional surface of the articulation is localized at the contact point between the pin 1 and the housing 11a of the connecting element, and more specifically between the pin 1 and the insert 5.

[0034] The present invention is not limited to the described embodiments, but may be implemented in many variants, for which reason Figures 4 to 7 show some variants of the invention, only the unique features of which are illustrated.

[0035] For example, as mentioned above, the attachment element 2 may take different shapes. Figure 4 shows a view from above of an embodiment corresponding to the embodiment described with reference to figures 1 to 3, in which the attachment element 2 occupies a large area of ​​the connection element 11.

[0036] Alternatively, the pin 1 may be prevented from rotating relative to the receiving element 21, in which case the connecting element 11 is rotationally movable relative to the pin 1. In a variant of this kind, the insert 5 forms the contact surface between the pin and the connecting element, as shown in the variants of figures 6 and 7, described below. For this reason, the insert 5 is accommodated in the connecting element 11. Furthermore, the pin may comprise a non-cylindrical first part, for example similar to the non-cylindrical part 1c described above, which is intended to be accommodated in the receiving element 21 in the protruding configuration. In particular, the pin 1 may also have a substantially inverted shape with respect to the pins described above, in which the first part forms a pivot that is accommodated in the housing of the connecting element, and the non-cylindrical part is directed towards the outside of the connecting element and is intended to occupy a protruding position in the receiving element in the fixed configuration. As a further alternative, the part of the pin that forms the pivot may correspond to a central position of the pin. Figure 7 shows such an embodiment diagrammatically.

[0037] According to a further variant, an attachment element may be provided on the receiving element for cooperating with the pin at the level of the receiving element. The cooperating may consist of blocking at least one degree of freedom of the pin, for example a translational movement and / or a rotational movement in order to hold the pin in the projected position. In one variant, a single attachment element or multiple attachment elements may cooperating with the connecting element and / or the receiving element. For example, the first attachment element may comprise an axial first abutment and the second attachment element may comprise a rotational second abutment. These first and second attachment elements may be arranged on the connecting element and on the receiving element, respectively, or vice versa.

[0038] For example, in this variant, the attachment elements may be fixed to each of the projections of the barrel 20. Figure 5 shows this type of variant, in which each opposing projection of the barrel includes an attachment element 2 removably mounted on each projection and arranged to cooperate with the pin to maintain its projecting position from the connection element, i.e. to prevent retractive translational movement into the connection element. In this variant shown in Figure 5, each pin 1 is rotationally immobilized by the connection element, at least when in the projected position, with respect to the connection element by means of a rotating second abutment 3, and rotation of each projection with respect to each pin is achieved by means of an insert accommodated in each projection.

[0039] In a further variant, the receiving element arranged on the torso may not have a shape with two protrusions, but may have, for example, the shape of a single protrusion. In this variant, the connecting element 11 arranged on the end of the wristband may take the shape of two complementary and separate lateral elements, each containing a pin 1, which are destined to take a position on either side of the single protrusion in order to fasten the wristband to the torso. Figure 6 illustrates the fastening configuration of this type of embodiment. The attachment element 2 is arranged on the receiving element in the shape of a single protrusion, each lateral element of the connecting element containing a protruding pin extending into a hole of the single protrusion. The attachment element 2 immobilizes these pins in the protruding position and in rotation relative to the receiving element. Each lateral element of the connecting element remains rotationally movable relative to the respective pin and contains an insert 5 between the pin 1 and the housing in which it is received. Finally, the torso may contain at least one protrusion, in particular one or two protrusions. Other body configurations are also envisioned, particularly those that include elements of the fastening device of the present invention that may not take the form of one or more protrusions.

[0040] In another variant, the fixation device may comprise one pin 1. Thus, the fixation device comprises at least one pin. Moreover, as is clear from the above description of the embodiments of the invention, at least one pin is not provided with a thread. It is noted that a pin can be movable in translation independently of being immobilized in rotation and vice versa.

[0041] As mentioned above, according to one embodiment, the connection element is arranged at the end of the wristband. If the wristband comprises an assembly of links, in particular metal links, the connection element advantageously takes the form of a connection link having the same or similar shape as the other links of the wristband, in order to give a continuous aesthetic appearance. According to a variant embodiment, the wristband may be made of a flexible material, for example leather. In this case, the connection element may be integrated, preferably in a completely or partially hidden manner, at the end of the flexible wristband. Alternatively, the connection element may take the form of a metal end piece arranged at the end of the flexible wristband.

[0042] In a further variant, the connecting element is arranged on the watch case, in particular on the body, and the receiving element on the wristband. For example, the configuration of the variant fastening device illustrated in figures 4 to 7 can be reversed: in all these figures, the receiving element 21 can be a link and the connecting element 11 can be one or more protrusions on the body.

[0043] In all the described variants, the insert may be positioned between the same pin and both the connecting element and the receiving element, so that the insert may surround the pin in whole or in part. This type of variant allows the best reduction of wear. Alternatively, in all the described variants, the insert is optional and may be omitted.

[0044] Complementarily, in all variants, the mounting element may comprise means acting on the pin to drive it in translation so as to automatically move the pin from the retracted position to the extended position and / or vice versa during positioning of the pin in the recess and / or during retraction from the connecting member and / or the receiving member.

[0045] Moreover, an embodiment, compatible with all the above-mentioned embodiments, is based on a fastening device in which the attachment element is removable. In such an embodiment, the attachment element is advantageously withdrawn from the fastening device when the fastening device is in the first configuration. The attachment element is fixed to said fastening device in the second configuration.

[0046] Furthermore, in all embodiments and variants, the pin is preferably made of ceramic, preferably based on zirconia, in particular made of sintered ceramic.

[0047] The invention also relates to a timepiece, in particular a wristwatch, as such, comprising at least one fastening device as described above. Fastening devices of this kind are advantageously arranged on either side of the small watch case, in particular on the body, for removable fastening of each end of the wristband.
