Definitions
- the present invention relates to the field of watchmaking, more particularly a timepiece comprising a rotary control member comprising a pattern.
- the controls of timepieces and in particular the winding crown bear a brand or logo on their external face for aesthetic reasons.
- the difficulty is to be able to guarantee that the control member is brought back in a determined orientation with respect to the watch case so as to display the brand or the logo in a visible manner and/or visible to persons other than the wearer of the watch case. the timepiece.
- EP1411401A1 describes a screw crown comprising a pattern such as a logo or a mark and in which the position of the logo or mark affixed to the end face of said crown can be easily adjusted in a position or orientation determined after screwing the crown onto the tube.
- EP2182417A2 describes a watch crown of the screw-in type making it possible to orient the crown in a determined position.
- the screw-down crown comprises a head having a front face provided with a logo with a non-circular geometry, a first tube intended to be kinematically connected to the movement, integral with the head and having a thread on its outer periphery.
- the crown to be screwed comprises a second tube arranged to receive the first tube, comprising, on the side of the first tube, an internal thread intended to cooperate with the thread of the first tube, and, on the side of the box, first indexing means .
- the screw-down crown further comprises a third tube arranged to receive the first and second tubes and comprising second indexing means cooperating with the first indexing means of the second tube, and a blocking member arranged to block the translational movement of the second tube relative to the third tube.
- JPS5111372 describes a crown formed by caulking a crown with a decorative plate in a drilled hole.
- a rectangular space is formed between the decorative plate and the bottom of the hole housing a mobile element which can move in the direction of the longitudinal force of the space by its own weight, and the movable member can be seen from the outside of the crown.
- the object of the present invention is to provide a timepiece comprising a rotary control member comprising a pattern such as a logo or a mark and in which the position of the pattern affixed to the end face of the control member remains fixed. in such a way as to facilitate the reading or the visibility of the pattern for the wearer or for any person other than the wearer.
- a timepiece comprises a rotary control member, the rotary control member comprising a hollow cylindrical body coaxial with the axis of rotation of the control member, the hollow cylindrical body defining a housing hollow interior comprising or supporting a coaxial rotating disc on which is arranged an adjustable pattern of the mark or logo type visible from the outside of the timepiece.
- the rotating disc rotates freely in a bidirectional manner around its axis in or on the hollow cylindrical body, the rotating disc cooperating with a moving device comprising an asymmetrically distributed mass to create an imbalance tending to cause the rotating disc to rotate around its axis when the timepiece is in motion or when the control member has been rotated, so that, seen from the outside, the pattern maintains a substantially fixed orientation.
- the displacement device comprises a rolling belt and a ball bearing integrated in the hollow housing.
- the rolling belt and the ball bearing are arranged between the asymmetrically distributed mass and the rotating disc.
- the timepiece in order to maintain complete sealing, comprises a sealing member arranged in the hollow cylindrical body, the sealing member comprising a fixed disc, parallel to the rotating disc, interposed between the asymmetrically distributed mass and a tube, the fixed disc being chased, glued or welded.
- the tube is arranged to fit into a recess arranged in the fixed disc.
- FIG. 1 shows an exploded view of a winding crown that can be arranged on a timepiece according to the present invention
- FIG. 2 shows a sectional view of a winding crown that can be arranged on a timepiece according to the present invention
- FIG. 3 shows a perspective view of a winding crown featuring a logo
- a rotary control member 12 comprises a hollow cylindrical body 9 coaxial with the axis of rotation of the control member 12.
- the hollow cylindrical body 9 delimits a hollow interior housing comprising a rotary disk 6 coaxial on which is arranged an adjustable pattern of the logo type (see FIG. 3) visible from the outside of the timepiece.
- the rotating disc 6 rotates freely around its axis in the hollow cylindrical body, the rotating disc 6 cooperating with a displacement device comprising an asymmetrically distributed mass 3 to create an imbalance tending to cause the rotating disc 6 to rotate around its axis when the timepiece is in motion or when the control member has been set in rotation, so that, seen from the outside, the logo maintains a fixed orientation.
- the displacement device comprises a rolling belt 7 and a ball bearing 1 integrated in the hollow housing, the rolling belt 7 and the ball bearing 1 being arranged between the asymmetrically distributed mass 3 and the rotating disc 6 .
- a sealing member in the form of a fixed disc 10 is arranged in the hollow cylindrical body 9, the fixed disc 10, parallel to the rotating disc 6, being interposed between the asymmetrically distributed mass 3 and a tube 2, the fixed disc 10 being chased, glued or welded.
- the tube 2 is arranged to fit into a recess arranged in the fixed disc 10.
- a beveled washer is fixed to the tube 2 by driving in, gluing or welding.
- a transparent glass crystal is arranged on the hollow cylindrical body 9, so as to make the rotating disc 6 visible.
- the winding crown rotates freely and can be decorated.
- This winding crown fitted with an imbalance creating an imbalance is driven by gravitational or inertial effect.
- a ring 8 surrounds the hollow cylindrical body so as to provide better grip for a user who manipulates the winding crown.
- a rotary control member 12 comprises a hollow cylindrical body 9 coaxial with the axis of rotation of the control member 12.
- the hollow cylindrical body 9 delimits a hollow interior housing supporting a disc coaxial rotary 6 on which is arranged an adjustable pattern of the logo type (see FIG. 3) visible from the outside of the timepiece.
- the rotating disc 6 rotates freely around its axis on the hollow cylindrical body, the rotating disc 6 cooperating with a displacement device comprising an asymmetrically distributed mass 3 to create an imbalance tending to cause the rotating disc 6 to rotate around its axis when the timepiece is in motion or when the control member has been set in rotation, so that, seen from the outside, the logo maintains a fixed orientation.
- the rotating disc 6 rotates bidirectionally thanks to the ball bearing allowing the rotating disc 6 to rotate freely relative to the hollow cylindrical body 9 under the effect of gravity or inertia.
- the rotating disc 6 is integral with an asymmetrically distributed mass 3 extending over an arc comprised by approximately 50% of the circumference of the hollow cylindrical body 9.
