    Description
    Technical Field [0001] The present invention relates to a shock detection device intended to be integrated in a portable object.
    The present invention also relates to a portable object provided with such a device, more particularly when the portable object is a timepiece.
    In general, in the rest of the text, "portable object" should understand any portable object that is electronic or mechanical, such as a watch, or a jewel.
    STATE OF THE ART [0004] Various devices for detecting an impact for a portable object are known from the state of the art, in particular by being arranged to fulfill the function of a control member and to actuate a function of the corresponding portable object.
    By way of example, US Pat. No. 3,963,885 describes a device for detecting a predefined acceleration which, when applied to a watch housing the detection device, makes it possible to activate a function such as the dial lighting. The device comprises a channel in which a ball can occupy at least one privileged position, by magnetic interaction with at least one fixed permanent magnet. The channel also has a cavity arranged such that the ball can be housed after leaving its preferred position, in response to the application of the predefined acceleration on the watch, in particular by sudden rotation of the wrist of the wearer. the watch. The cavity contains electrical contacts associated with an open electrical circuit that the ball allows to close when it is in the cavity. The ball is then preferably returned to its preferred position, orienting the watch in a certain way to extract it from the cavity to open the electric circuit.
    Thus, the shock detection device presented in this document is intended to be used repeatedly and, if a threshold must necessarily be predefined by construction for the detection of shock (here the force to overcome the interaction magnetic between the ball and the permanent magnet), the return to the initial state must be relatively easy to allow the detection of a subsequent shock.
    Disclosure of the invention [0007] A main object of the present invention is to propose an alternative construction to known constructions for producing a shock detection device for a portable object intended to fulfill a function different from the functions already known for this type. detection devices, and with a mode of operation different from the known operating modes. More specifically, a main purpose of the shock detection device according to the present invention is to memorize the occurrence of a predefined intensity shock, in particular to identify the fall of a portable object which would imply a malfunction but whose repair would then be excluded from coverage under warranty.
    For this purpose, the present invention relates more particularly to a shock detection device for portable object, characterized in that it comprises a base and a suspended mass connected to the base via a portion of reduced section, the device having a predefined shape in a first state of rest, as well as predefined mechanical properties such that the portion of reduced section is likely to present an elastic deformation, before returning to its shape corresponding to the first state, in response to the application on the device of a value acceleration lower than a predefined threshold value in at least a first predefined direction, that the device occupies a second, stable state, in which it has a shape different from the predefined shape in response to the application on the device of a value acceleration greater than the value r predefined threshold following at least the first predetermined direction, associated with a shock, to memorize the occurrence of the shock in question.
    With these characteristics, we obtain a device for not only detecting the occurrence of a predefined intensity shock but also to memorize it. Thus, if the owner of the portable object uses the manufacturer's after-sales service because the portable object is malfunctioning, the after-sales service is able to determine whether the portable object has suffered a shock. intensity as it would be excluded from the guarantee.
    The shock detection device according to the present invention provides an objective tool for qualifying an event leading to the exclusion of warranty support. Manufacturers are currently relying, for example, on visible damage to the casing of a portable object to justify the exclusion of warranty coverage. This approach, however, lacks reliability, especially depending on the material of which the housing is made. A gold watch case will be much more easily marked in a fall than a steel or ceramic case (the latter, on the other hand, may break).
    [0011] In a different way, the detection device according to the present invention will undergo a modification of its state not in response to a direct impact but in response to a predefined intensity acceleration, thus leading to a much more reliable result. .
    In the context of the present invention, it is necessary to understand the notion of shape in a broad manner, in the sense that the change in shape between the first and second states can also be a simple change in appearance, such as a mark made on at least one of the components of the device during a collision between this component and another component of the device, due to the deformation of the reduced section portion. In all cases, it should be noted that the shape change concerned should preferably be visible to the naked eye at a distance of the order of 30 cm.
    According to various alternative embodiments of the detection device according to the invention, it can be provided that it has mechanical properties such that it occupies a third stable state, in which it has a different shape of the shape. predefined, in response to applying an acceleration value greater than the predefined threshold value in at least a second predefined direction, or even occupying a fourth, stable state, in which it has a shape different from the predefined shape in response to applying an acceleration value greater than the predefined threshold value in at least a third predefined direction.
    According to an alternative embodiment, it can be provided that the reduced section portion has an at least partial break in the second state.
    In general, it can be provided that the transition from the first state to the second state involves a plastic deformation of the suspended mass and / or the base and / or the reduced section portion.
    Alternatively, it can be provided that the transition from the first state to the second state involves an elastic deformation of the portion of reduced section, and that the device comprises at least one locking member arranged to cooperate with the suspended mass or with the portion of reduced section to lock the latter in the second state in response to the application on the device of an acceleration value greater than the predefined threshold value.
    In general, it can be provided that the base, the reduced section portion and the suspended mass are made in one piece.
    The present invention also relates to a portable object comprising a detection device meeting the characteristics set out above.
    According to a preferred embodiment of the invention, the portable object may be a timepiece. In this case, it can advantageously be provided that the detection device is directly integrated in a component of the timepiece, either a component of the covering or a component of the watch movement, preferably being made in one piece with this component.
    BRIEF DESCRIPTION OF THE DRAWINGS [0020] Other features and advantages of the present invention will appear more clearly on reading the detailed description of preferred embodiments which follows, made with reference to the appended drawings, given by way of non-limiting examples. and in which: FIGS. 1a and 1b show simplified views, respectively from the front and in perspective, of a device for detecting and storing an impact according to a first preferred embodiment of the invention; figs. 2a and 2b show simplified views, respectively from the front and in perspective, of a device for detecting and memorizing an impact according to a first variant embodiment of the embodiment of FIGS. 1a and 1b; figs. 3a and 3b show simplified views, respectively of front and in perspective, of a device for detecting and memorizing an impact according to a second variant embodiment of the embodiment of FIGS. 1a and 1b, and FIGS. 4a and 4b show simplified views, respectively front and perspective, of a device for detecting and storing an impact according to a second preferred embodiment of the invention.
    Embodiment (s) of the invention [0021] FIGS. 1a and 1b show simplified views, respectively from the front and in perspective, of a device 1 for detecting and memorizing an impact according to a first preferred embodiment of the invention.
    A basic principle of implementation of the present invention to provide that the device 1 for detection and storage comprises a mass 2 suspended from a base 4 via a portion 6 of reduced section.
    In the first embodiment of FIGS. 1a and 1b, the base 4 has been shown schematically in the form of a substantially parallelepipedal plate, the suspended mass 2 having substantially the shape of a drop.
    The suspended mass 2 can be reported on the base 4 through the portion 6 or, alternatively, two or three of these components can be made together in one piece.
    The base 4 can be made integral, by any means or known and adapted method, any suitable component of a portable object, whether electronic or mechanical, such as a watch, or a jewel. For example, the base 4 can be secured to a support of the portable object by screwing, gluing, crimping, welding, or by a connection by casing.
    Alternatively, the detection device 1 according to the invention can also be directly made in one piece with a component of the portable object. For example, the device 1 could be integrated into a component of the dressing of a wristwatch, in particular by etching the box or the casing ring, or even a component of the watch movement such as platinum. .
    The manufacturer of the portable object concerned will not encounter any particular difficulty to define what level of acceleration, defined by a threshold value, the portable object is able to support, taking into account any specific guidance, including in the event of a fall ending in a shock likely to cause a high value acceleration to the portable object in question.
    The device 1 for detection and storage, intended to be embedded in this portable object, can then be precisely shaped and dimensioned to react in response to the occurrence of an acceleration whose value exceeds the threshold value that the object portable is able to support.
    The exact shape and dimensioning of the component parts of the detection device 1 depend in particular on the material or materials used for its production. Those skilled in the art will not encounter any particular difficulty in choosing one or more materials adapted to their own needs, such as, for example, a metal or metal alloy, a plastic, a ceramic, silicon, etc.
    Note that the suspended mass 2, in particular, may optionally be made as a composite element, that is to say that it may be formed by the assembly of several portions possibly made of different respective materials. Its mass will not necessarily be distributed in its volume homogeneously.
    Of course, the skilled person will advantageously take into account the mode of connection between the detection device 1 and the housing of the portable object, particularly if this mode of connection is not completely rigid and can give partial shock absorption by intermediate connecting elements.
    The detection device 1 illustrated in FIGS. 1a and 1b will react differently to accelerations of the same value but which would have different orientations. It appears in fact that the portion 6 of reduced section is shaped here to be more fragile against constraints that would be oriented so as to be close to or in the plane of the base 4 being inclined with respect to the axis X of the suspended mass 2.
    Preferably, it can be provided that the portion 6 of reduced section undergoes elastic deformation in response to the occurrence of an acceleration value less than the predefined threshold value, in at least one given direction.
    On the other hand, since the acceleration undergone has a value greater than the threshold value, the portion 6 of reduced section passes from its first state, at rest, to a second state, stable.
    This second stable state can here either correspond to a state of plastic deformation, that is to say that the portion 6 of reduced section does not return to its original shape, or possibly at least a partial break, or even complete , portion 6 of reduced section.
    In one case as in the other, an after-sales service operator who would be called upon to intervene on the portable object concerned could easily see that it has undergone an acceleration value greater than the predefined threshold value. by construction, which could advantageously correspond to a fall under predefined conditions (height, type of soil). Thus, the intervention in after-sales service could be excluded from the guarantee without possibility of dispute for the owner of the portable object.
    In general, it can also be provided that the portion 6 of reduced section deforms or breaks in response to the occurrence of an acceleration that would be mainly oriented in a direction perpendicular to the plane of the base 4, in particular by choosing a suitable thickness of the base 4 taking into account the mechanical properties of the material used.
    Alternatively, it is also possible for a given portable object to be provided with several similar or even identical detection devices 1, but assembled to the portable object with different respective orientations, to ensure the detection of accelerations in a manner that precise according to several orientations.
    Figs. 2a, 2b show simplified views, respectively from the front and in perspective, of a device 10 for detecting and memorizing an impact according to a first variant embodiment of the first embodiment of FIGS. 1a, 1b.
    The operating principle of the device 10 is identical to that of the first embodiment.
    The hanging mass 12 here has the shape of a disk, preferably made by removing material in the base 14, forming at the same time the portion 16 of reduced section, here in the form of S.
    It is understood that the implementation of the present invention is not limited by the choice of the shape of the components of the detection device. For example, a suspended mass may be produced which has a shape corresponding to the logo of the manufacturer of the portable object.
    Figs. 3a, 3b show simplified views, respectively from the front and in perspective, of a device 20 for detecting and storing an impact according to a second variant embodiment of the first embodiment of FIGS. 1a, 1b.
    The operating principle of the device 20 is similar to that of the first embodiment.
    The suspended mass 22 here has the shape of a cylinder connected to a base 24 in the form of a pellet, via a portion 26 of reduced section here having the shape of two cones oriented with their vertices being made face to define between them a zone 28 more favorable to the deformation or breaking.
    With the detection device 20, it is noted that the detection will be done in the same way for a given value of acceleration for all the radial accelerations contained in the same plane perpendicular to the Y axis of symmetry of the suspended mass. 22.
    While the various variants presented above in relation to the first embodiment correspond to detection devices which must preferably be replaced after the occurrence of an intensity shock exceeding the threshold, it is also possible to provide other constructions leading to reusable detection devices.
    Figs. 4a and 4b show simplified views, respectively front and perspective, of a device 30 for detecting and storing an impact according to a second preferred embodiment of the invention.
    The detection device 30 has a shape generally similar to that of the device 10, that is to say a suspended mass 32 in the form of disc, in a non-limiting manner, connected to the base 34 via a portion 36 of reduced S-shaped section.
    However, the suspended mass 32 is provided here with a tip 38 diametrically opposite the portion 36 of reduced section and intended to cooperate with one or the other of two pawls 40 extending symmetrically from the base 34 towards the tip 38, to act as locking members of the suspended mass 32.
    It is understood from Figs. 4a, 4b that in response to the application of an acceleration which would include a component contained in the plane of FIG. 4a and inclined relative to the direction passing through the portion 36 and the tip 38, the suspended mass 32 moves laterally. If the value of the acceleration applied exceeds a threshold value, the tip 38 can engage in one or the other pawl 40 depending on the direction of application of the acceleration.
    The skilled person will not encounter any particular difficulty to size the tip 38, the pawls 40 (including their depth of penetration) and the distance between them to ensure a desired holding once the tip 38 is engaged in a pawl 40, to prevent the detection device from resuming its first state of rest inadvertently.
    Thanks to these features, the operator involved in an after-sales service operation can easily see the occurrence of a shock making the warranty inapplicable and can easily return the detection device 30 without being in condition replace it.
    Variants are of course conceivable. By way of example, provision may be made for the portion 36 of reduced cross-section to bear a hook on each side intended to cooperate with a corresponding hook extending from the base 34, with either hook being at least slightly deformable in an elastic manner to allow mutual snapping without allowing untimely mutual release.
    It follows from the above that the detection device as described above can accurately and reliably detect a shock that would have suffered a portable object that would be provided and which would result in make the manufacturer's warranty inapplicable to remedy a malfunction that would result. Such a device will allow the manufacturer to make substantial savings in after-sales service interventions and will avoid unpleasant discussions with customers who would eventually have denied the occurrence of a shock justifying the lifting of the guarantee.
    The foregoing description attempts to describe a particular embodiment by way of non-limiting illustration and, the invention is not limited to the implementation of certain particular features which have just been described and illustrated, such as the exact structure of the detection device that has been described or the shapes illustrated and described for the different parts of the detection device. As previously indicated, the components of the detection device may be manufactured in one or more parts, without departing from the scope of the invention. Moreover, as has also been mentioned above, the change of shape between the first and second states of the detection device can also be a simple change in appearance, such as for example a mark made on at least one of the components. of the device during a collision between this component and another component of the device, due to the deformation of the reduced section portion. Indeed, a mark can be considered as the result of a plastic deformation. Thus, the suspended mass could be marked following a shock against the inner wall of the base facing it. The inner wall of the base which has suffered the shock of the suspended mass could also be marked, while the reduced section portion could have a different shape after the shock than it had before the shock.
    Those skilled in the art will not encounter any particular difficulty in adapting the content of the present disclosure to their own needs and, implement a detection device or a portable object comprising such a detection device, in particular a test piece. watchmaking including such a detection device, only partially meeting the described characteristics, including in particular a suspended mass connected to a base via a reduced section portion capable of permanently deforming or breaking in response to the application of an acceleration of sufficient value, without departing from the scope of the invention.
