Definitions

  • the present invention relates to a timepiece component equipped with at least one cap. It also relates to a timepiece comprising such a timepiece component. It also relates to a method of manufacturing such a timepiece component.
  • a general object of the invention is to propose a new watch component solution equipped with a cap, which improves the existing solutions, by meeting the abovementioned requirements as well as possible.
  • an object of the invention is to provide a watch component solution equipped with a cap that is robust, reliable, simple to implement, and able to present an attractive aesthetic appearance.
  • the invention is based on a watch component having a first part and a removable cap, the watch component being able to occupy a fixing configuration in which the removable cap is fixed on the first part and a free configuration in which the cap is separated from the first part, the first part comprising at least a first hooking member and a movable lock and the cap comprising at least a first assembly member intended to cooperate with the first hooking member of the first part and a second assembly member intended to cooperate with the mobile lock of the first part, so that in the configuration for fixing the timepiece component, the first attachment member of the first part and the first assembly member of the cap are in engagement, and the movable latch occupies a closed position in which it is in engagement with the second member for assembling the cap , so that the cover is fixed in a locked manner on the first part, and so that in the free configuration, the movable lock occupies an open position in which it releases the second assembly member of the cover, allowing the separation of the cap from the first part of the timepiece component.
  • the figure 1 represents a bracelet clasp according to one embodiment of the invention.
  • This clasp comprises two blades 1, 2 articulated by one of their ends around an axis.
  • the free end of blade 1 is integral a first hinge pin serving for the hinge of a complementary cover 7, 7c and a second hinge pin serving for the hinge of one end of one of the bracelet strands.
  • the free end of blade 2 is secured to a mobile structure 3 articulated in rotation.
  • the clasp can thus occupy an open position, as represented by the figure 1 partially deployed, and a closed position in which the second blade 2 and the structure 3 are folded and locked on the first blade 1.
  • the end of a first bracelet strand is fixed on the second end of the first blade 1 and the end of a second bracelet strand is fixed to the free end of the mobile structure 3.
  • the invention relates more specifically to a cover of the clasp.
  • This cover is mainly integrated into the structure 3 of the clasp.
  • the cover comprises a first part 13 which has a vertical cross-section in the shape of an inverted U, having an upper face visible to a user, and two side walls, substantially perpendicular to the upper face, intended to laterally cover the entire clasp and of its mechanism, to conceal it in the closed position and ensure the aesthetic appearance of the solution.
  • the lid further comprises a removable cap 13c.
  • the cover can thus occupy a fixing configuration in which the removable cap 13c is fixed on the first part 13 and a free configuration in which the cap 13c is detached from the first part 13.
  • the clasp comprises a complementary cover 7, 7c arranged on the first blade 1 and intended to come down in the closed position of the cover to position itself in the continuity of the cover arranged on the mobile structure 3 and also cover a lever of lock 12, and thus form a single cover of the clasp including a security.
  • This complementary cover part has a structure similar to that described above, that is to say a first part 7 cooperating with a removable cap 7c. It can be assembled according to the same concept as the invention or not. It will not be described in more detail below.
  • the upper surface of the first part 13 of the cover has a planar orthogonal projection of substantially rectangular shape.
  • the cap 13c is presented as a substantially planar and elongated element which extends over the entire length of the upper surface of the lid and over a portion of the width of the upper surface of the lid, for example over a portion of the width of the upper surface of the cover between 20% and 100%, or even between 30% and 90%, or even between 45% and 55%. It is centered or not on the lid.
  • the cap 13c is arranged in a recessed portion of the first part 13, in the thickness of the upper surface of the first part of the cover, so that it covers this second recessed portion and occupies the volume released by this recessed portion.
  • the upper surface of the cap thus comes in continuity with the upper surface of the first part, forming a generally continuous upper surface of the lid.
  • the upper surface of the cap is recessed or protrudes from the upper surface of the first part.
  • the figure 2 shows a sectional view through a vertical longitudinal median plane of the cover according to the embodiment.
  • the picture 3 shows an exploded view without locking lever 12.
  • These figures show the device for fixing the cover 13c to the first cover part.
  • the cap 13c comprises at least a first assembly member 40 and a second assembly member 41, which are arranged at the two opposite distal ends, on the side of the surface of the cap 13c intended for orientation towards the first part 13 of the cover, i.e. the lower surface of the cap according to the chosen convention.
  • the first part 13 of the cover comprises at least one first attachment member 50 and a movable lock 9.
  • the first assembly member 40 of the cap 13c cooperates with the first attachment member 50 of the first part 13, and the second assembly member 41 of the cap 13c cooperates with the movable lock 9 of the first part 13 , in particular a second attachment member 51 integral with the latch 9.
  • the first attachment member 50 of the first part 13 and the first assembly member 40 of the cap 13c are made of socket.
  • the second attachment member 51 of the first part 13 and the second assembly member 41 of the cover 13c are also engaged.
  • the cap 13c is presented as a one-piece element. It may also advantageously be in a material other than the material of the first part 13, in particular a material which has mechanical properties of resistance to shocks and scratches and/or is capable of presenting a very attractive aesthetic appearance, for example a ceramic, cermet, glass, sapphire, mother-of-pearl, amber or natural or reconstituted stone. As a variant, it may be in metal and/or in the same material as that of the first part 13.
  • the first part 13 of the cover is made of a metal alloy, for example stainless steel, gold, platinum, bronze or titanium.
  • the mobile lock 9 can occupy a closed position and an open position, according to an operation which will be detailed later. It comprises an attachment member 51 intended to cooperate with the second assembly member 41 of the cap 13c.
  • the first part 13 preferably comprises a first opening 16 arranged in each of these side walls, in the form of a cutout in the inner surface of these side walls, and the movable latch 9 comprises a latch opening 6, said first opening 16 and latch opening 6 being arranged so that they come substantially face to face in the closed position of the latch 9.
  • a retractable bar 11 is capable of cooperating with said first opening 16 and lock opening 6 in the closed position of the movable lock 9, as illustrated in figure 9 , so as to lock this closed position of the mobile lock 9 and thus lock the fixing configuration of the cover.
  • the cover further comprises a backlash element 22 interposed between the lock 9 and the cap 13c, being of flexible and/or deformable material, adapted to be compressed between the cap 13c and the lock 9 when the lock 9 is in its first closed position and/or against which the movable lock 9 comes into abutment in its closed position.
  • This backlash element makes it possible to overcome the mobility induced by manufacturing tolerances.
  • the two assembly members 40, 41 of the cap have a hook-shaped section extending over the entire width of the cap and forming notches cooperating with complementary shapes of at least one hooking member 50 of the first part 13 and at least one hooking member 51 of the lock 9.
  • the figure 4 shows an exploded view of an alternative embodiment.
  • the geometry of the second attachment member 51 intended to cooperate with the second assembly member 41, itself limited to a portion of the width of the cap 13c, is in the form of a notch integrated into the lock 9.
  • the invention is not limited to the examples and variant embodiments described.
  • any other number of attachment members of the first part and assembly members of the cap is possible.
  • These bodies can also be in another form, and at a different position.
  • these members may be in the form of a hook and/or a notch and/or a recess and/or a groove and/or a lug and/or a beam .
  • the cap could take any other shape, and any other positioning on the first part, not necessarily centered. It can be presented in another geometry.
  • the figure 5 represents a first assembly phase in which the first assembly member 40 of the cap 13c is associated with the attachment member 50 of the first part 13.
  • the cap 13c is then folded over the first part 13, by pivoting around an axis formed by the connection between the members 40, 50, until reaching the intermediate configuration represented on the figure 6 .
  • the mobile lock 9 occupies an open position, permitted by a release cutout provided in the lid.
  • the bar 11 allowing the locking of the lock 9 in the fixing position is not illustrated, to make it possible to visualize the offset between the first opening 16 and the opening of the lock 6 in the open position.
  • the pivots 11a of the bar 11 are retracted as illustrated in figure 10 .
  • the cap occupies its final position, but is not locked, which allows its removal.
  • the movable latch 9 indeed occupies its open position, in which it is not engaged with the second assembly member 41 of the cover 13c. Bar 11 inserted in the latch opening 6 is not positioned opposite the first openings 16; its pivots 11a are retracted as shown in figure 10 .
  • the latch 9 is then moved to its closed position, in which its attachment member 51 comes into engagement with the second assembly member 41 of the cap 13c.
  • the cover thus achieves its fastening configuration shown in the figure 7 , in which the release of the cap 13c is no longer possible.
  • the lock opening 6 of the lock 9 is substantially aligned with the first two corresponding openings 16 of the first part 13.
  • the pivots 11a of the strip 11 can thus be insert into these first two openings 16 and maintain the locked position as shown in figure 9 .
  • the cap 13c is thus locked on the first part of the cover 13.
  • the lock 9 is therefore mounted to move in translation within the lid.
  • it could be mounted in slideways arranged in the side walls of the first part 13 of the cover, which guide it in its movement.
  • the translational movement is therefore guided by these slideways and can be substantially longitudinal, or even slightly curved to follow the curvature of the cover.
  • the translation mentioned is therefore not limited to a rectilinear translation, it could be curved, or even circular.
  • the lock 9 could be arranged differently and mobile according to another movement, such as a rotation.
  • the latch opening 6 of the latch 9 and the opening 16 of the first part 13 are slightly offset in the closed position of the latch so that the cooperation of the removable bar 11 with said two openings in the closed position of the mobile lock 9 makes it possible to exert a force on the lock 9 against the first part 13 of the cover and/or against the second member assembly 41 of the cap 13c.
  • the strip 11 thus presses the assembly member 51 of the lock 9 onto the cover 13, generating a tension on the cap 13c via a slight bending of the strip 11, thus making it possible to guarantee a holding in position precise and without play of the cap 13c on the first part 13 of the cover.
  • the figure 8 shows a plan view of the clasp closed in the fixing configuration according to the embodiment of the invention from the face opposite that comprising the cap (lower face).
  • the figures 9 and 10 are enlargements of the z-zone of this figure 8 .
  • the strip 11 advantageously comprises strip pivots 11a which are retracted in the open position of the lock 9 and during its movement, and which are released, as illustrated in figure 9 , to enter the first openings 16 of the first part 13 of the cover in the closed position of the cover.
  • the invention therefore applies to any embodiment in which the first part 13 comprises at least one first opening 16.
  • the invention also relates to a timepiece, in particular a wristwatch, comprising at least one timepiece component as described above.
  • the invention also relates to a bracelet, characterized in that it comprises a clasp as described above.
  • the invention also relates to a wristwatch comprising such a bracelet.
  • the invention also relates to a method for manufacturing a timepiece component, characterized in that it comprises a step of fixing a cap 13c to a first part 13 of the timepiece component, by assembling a first assembly member 40 of the cap 13c with a first hooking member 50 of the first part 13, then by positioning the cap 13c in its final position provided in the configuration for fixing the watch component, then by actuating a movable lock 9 of the first part 13 to bring it into a closed position in cooperation with a second assembly member 41 of the cap 13c.
  • This method comprises an additional step consisting in locking the closed position of the mobile lock 9 on the first part 13 using a bar 11.
