    The appended drawing represents, by way of example, an embodiment of a device according to the invention.<tb> Fig. 1 <SEP> is a sectional view of the embodiment of the flotation device, the inflation trigger being deactivated.<tb> Fig. 2 <SEP> is a sectional view of the embodiment of the flotation device, the inflation trigger being activated.
    An embodiment of a timepiece 110 according to the invention is described below with reference to FIGS. 1 and 2 . The timepiece is for example wristwatch. The timepiece includes:a clasp 51 or a sensor 52 for the presence of the wrist of a user, anda flotation device as described below.
    The timepiece includes an organ such as a clasp or a wrist presence sensor of a user. This member comprises a movable element 5. This movable element can be moved between a first position and a second position. In the case of a clasp, the movable member can be moved between a first closed clasp position and a second open clasp position. In the case of a wrist presence sensor of a user, the movable member can be moved between a first position determined by the presence of the wrist of the user and a second position determined by the absence of the wrist of the user. 'user.
    In the embodiment, the flotation device mainly comprises:a gas tank 1,a pocket 2,a trigger 3 for inflating the pocket by means of the gas, andan activation / deactivation element 4 of the inflation trigger.
    The activation / deactivation element is intended to be linked to the movable element and arranged so that the trigger is deactivated when the movable element 5 is in a first position and so that the trigger is activated when the movable element 5 is in a second position. To do this, the activation / deactivation element preferably comprises a connecting element making it possible to link it to the mobile element. The clasp is therefore not part of the flotation device.
    The overall operating principle of the flotation device is as follows. When the clasp of the wristwatch is open and / or when the watch is not on the wrist of the wearer or the user, in case of immersion at a given depth, the trigger commands a communication of the gas tank and the pocket. The gas is under pressure in the tank, it migrates to the pocket that inflates. Once the bag is inflated, the Archimedes thrust allows it to rise to the surface with the watch. Therefore, the watch must be recovered without difficulty.
    When the clasp of the bracelet is closed or when the watch is on the wrist of the wearer, the pocket is not inflated, even if the flotation device is immersed, regardless of the depth of immersion.
    The flotation device generally has a cylindrical shape. The device has a longitudinal axis 9. It comprises, for example, a body 6 in which the gas reservoir 1 is made.
    Preferably, the release comprises a pressure sensitive element 31 and a valve 32.
    The pressure sensitive element is mechanically connected to the valve. Thus, the pressure of the liquid in which the flotation device is immersed can control the valve. It follows that the valve can be controlled when the flotation device is immersed at a given depth. The valve allows or not, depending on its state, the transfer of gas from the tank to the pocket.
    The pressure-sensitive element preferably comprises a piston 311. Complementarily or alternatively the pressure-sensitive element may comprise a membrane.
    Preferably, the valve may comprise a shaft 321 and an orifice 322 of the reservoir, the shaft being mounted movably in the orifice. Thus, in a closed position of the valve, the shaft closes the orifice and, in an open position of the valve, the shaft does not completely close the orifice.
    Advantageously, the pressure sensitive element is mechanically connected to the shaft and the latter is moved according to the pressure exerted on the pressure sensitive element. For example, the pressure exerted on the piston 311 moves the latter to the reservoir. This displacement causes via an intermediate element, such as a bistable element 323, in particular a bistable washer 323, a displacement of the shaft in the opposite direction. This displacement of the tree, as depicted in FIG. 2, opens at least partially the orifice 322.
    Preferably, the activation / deactivation element comprises a shutter 41 or a cover movable between a first position and a second position. In a first position of the activation element, in particular in a first position of the shutter shown in FIG. 1, the shutter isolates the shutter from the ambient pressure. In this first position, the shutter may alternatively or additionally prohibit the operation of the shutter In a second position of the activation element, in particular in a second position of the shutter shown in FIG. 2, the shutter submits the shutter of the ambient pressure. To do this, in the first position, the shutter is applied to the body 6 of the flotation device and, in the second position, the shutter spaced from the body 6. To ensure the isolation, the shutter and / or the body comprises a seal, for example an O-ring 411.
    As seen above, the activation / deactivation element is connected to the movable element 5 via a mechanical link. This mechanical connection can be direct, that is to say that the movable element and the activation / deactivation element can be come or made in one and the same piece or linked to each other by any type of direct mechanical connection. Alternatively, the mechanical connection may be indirect, that is to say that one or more intermediate parts may be provided between the movable element and the activation / deactivation element.
    Advantageously, in its first position, the activation / deactivation element acts mechanically on the trigger. In the embodiment, the shutter acts mechanically on the piston and on the shaft. This action is for example performed through the inner face 413 and through a boss 412 provided at the bottom of the shutter. The internal face acts by direct contact on the piston and the boss acts by direct contact on the shaft 321. Thus, each time the shutter passes from the second position to the first position, it acts on the shaft and on the piston causing a small displacement of the latter. These small movements are intended to prevent seizure of the mechanism that would make it inoperative. Moreover, the action of the boss 412 on the shaft prohibits any opening of the valve in the first position of the shutter. This prohibition is important because it ensures operational safety even in case of failure of the seal made at the joint 411.
    Advantageously, the trigger is configured to cause a change of state of the valve when it is subjected to a pressure greater than a first threshold pressure, for example 10 kPa, 15 kPa or 20 kPa. Thus, the valve is open when the pressure exceeds the first threshold pressure.
    Preferably, a cover 7 is mounted on the body, in particular is mounted clipped on the body 6. The cover is preferably made of plastic. The cover is provided to cover the pocket 2, that is to say that the hood provides a cavity in which the pocket is housed in a folded state. The resistance of the cover and / or the clipping is such that when the valve is open and the bag is inflated by the gas pressure, the cover is ejected or broken to allow the bag to inflate freely. Inside the hood, a wax, a gel, or a viscous liquid may be provided to fill the free space between the folds of the pocket. Thus, it is avoided that the pressure of the water during the immersion flotation device can deform the cover 7.
    Preferably, the flotation device generally has a cylindrical shape. For example, the body 6 and the cover 7 have outer sections of substantially identical shapes and / or dimensions. Preferably, the activation / deactivation element is provided at one end of the flotation device and the cover covering the pocket is provided at the other end of the flotation device.
    The pocket is preferably made of a membrane of a flexible or elastic synthetic material. Thus, the bag can deform, in particular expand, when subjected to an inflation pressure. Advantageously, the pocket may be made of a phosphor or covered with a phosphor. Thus, it can be charged with energy when it is lit and scatter light in the dark. The pocket can also be brightly colored like red or orange. The appearance of the pocket makes it easier to detect on a body of water.
    [0030] A more detailed description of the operation of the flotation device is given below.
    When the activation / deactivation element is in a deactivation state of the inflation trigger, as shown in FIG. 1, the shaft 321 can not be moved in translation and completely closes the orifice 322. Indeed, the boss 422 of the shutter comes into contact against the end of the shaft 322. In addition, the shutter 41 tightly closes a chamber in which the piston 311 is located so that the piston is not subjected to the surrounding pressure flotation device. Therefore, regardless of the immersion depth of the flotation device, the bag 2 can not be inflated with the gas contained in tank 1.
    When the activation / deactivation element is in an activation state of the inflation trigger, as shown in FIG. 2, the shutter 41 opens the chamber mentioned above and the piston 311 is subjected to the pressure of the fluid surrounding the flotation device. Therefore, as the depth of immersion of the flotation device increases, the pressure to which the piston 311 is subjected increases. The piston is held as shown in FIG. 1, at a distance from a wall of the tank with the aid of an intermediate element 323, in particular a bistable element, in particular a bistable spring washer. The spring washer has a substantially conical shape and is pierced at its center. It is in contact with its outer radius with the piston and in contact with an intermediate radius with the reservoir. It is also in contact at an inner radius with a shoulder provided on the shaft 322. As the pressure increases, the piston moves to the right and progressively deforms the washer. The washer being of the bistable type, it suddenly deforms to reach the state shown in FIG. 2. During this deformation, the inner radius of the washer moves to the left and acts on the shoulder provided on the shaft 321. It follows that the shaft 321 is moved to the left as shown in FIG. 2. As a result, the shaft is displaced relative to the orifice 322 provided in the reservoir. In particular, the shaft 321 comprises a groove 331 facing a seal 332 provided at the orifice and intended to seal with the shaft. In the position shown in FIG. 2, the sealing at the orifice 322 is no longer ensured by the cooperation of the seal and the shaft and the gas contained in the tank 1 can escape to supply the pocket 2 which is inflated.
    The invention also relates to the flotation system comprising a first flotation device as described above and a second flotation device as described above. The flotation device may have an aesthetic appearance evoking marine elements of substantially cylindrical shape, such as a torpedo, a fender or a scuba diving bottle.
    [0034] Advantageously, the first flotation device includes a first trigger comprising a first valve and the second flotation device includes a second trigger comprising a second valve. The first trigger is configured to cause a change in state of the first valve when it is subjected to a pressure greater than a first threshold pressure, for example 10 kPa, 15 kPa or 20 kPa, and the second trigger is configured to cause a change of state of the second valve when it is subjected to a pressure greater than a second threshold pressure, for example 10 kPa, 15 kPa or 20 kPa. The second threshold pressure is preferably greater than the first threshold pressure. Thus, if the first pocket of the first flotation device does not inflate as expected or insufficiently inflates and the wristwatch continues to flow, the second trigger of the second flotation device can trigger the inflation of the second pocket of the second device flotation when a second depth (corresponding to the second pressure) is reached.
    For example, the first and second flotation devices are arranged side by side, their longitudinal axes being parallel and remote.
    [0036] The invention also relates to a bracelet 100 for a timepiece comprising a clasp 51 and a flotation device 10 as described above or comprising a clasp 51 and a flotation device 10 as described above.
    The flotation device and the flotation system have been described above applied to a timepiece or a bracelet or a bracelet clasp. The device and the system can of course be applied to other objects, in particular jewelry bracelets or clasps, key rings.
