Definitions

  • these crowns project on the edge and in a radial direction of the watch case, and are movable axially between a pushed position in which the rotation of the crown controls the reassembly of the watch and a fired position in which the rotation of the crown control the time setting.
  • document FR 1.181.584 discloses a device for reassembly and time setting including a crown protruding from the upper face of the watch so that its axis is perpendicular to the plane of the movement.
  • This crown can take a first axial position, or high position, in which it cooperates with a winding mechanism and a second axial position, or low position, in which it cooperates with a time-setting mechanism, a return spring bringing the crown back into high position as soon as it is released by the user.
  • Also known from EP 1.310.839 is a device for reassembly and time setting including a crown protruding from the upper face of the watch, crown adapted to rotate in a control rod movable axially in the plane of movement and operable by the user.
  • a control rod When the control rod is in an axial position pressed, a rotation of the crown printed by the user and transmitted by the crown to the control rod causes the watch to reassemble.
  • the control rod is in an axial drawn position, a rotation of the crown printed by the user and transmitted by the crown to the control rod allows the time setting of the watch.
  • the present invention aims to provide an alternative to these devices.
  • a timepiece including a box, a mechanism housed in the box and a rotary actuator manipulable by a user, characterized in that the rotary control member is movable in translation with respect to the box in a direction substantially perpendicular to the axis of the rotational control member between first and second positions, and in that at least one of these first and second positions a rotation of the rotary member controls a function of the mechanism.
  • the crown 10 protrudes on the upper face of the watch case, in a recess 12 of this face (see Figure 2), and its axis, designated by the reference A, is perpendicular to the plane of the movement 6, more generally to the plane of the watch case 1.
  • the ring 10 is located near the edge of the aforementioned upper face and the part of the watch constituted by the movement 6, the dial 8, the hands 9 and the ice 5 is eccentric with respect to the axis of the watch case to leave room to the crown 10 and to the connecting mechanism 11 and to give the watch an appearance particular aesthetic.
  • part 6, 8, 9, 5 This could be for example in the form of a circle centered on the axis the watch case and scalloped on board to leave room for the set 10, 11 or a rectangle of which one of the corners is truncated.
  • the ring 10 comprises a head 13 that can be manipulated by the user and a axial extension 14 generally cylindrical and formed integrally with the head 13.
  • This axial extension 14 extends into the opening 15 of a tube of crown 16 hunted in a large section top section 17 of a through bore made in the bezel 4.
  • the opening 15 of the crown tube 16a in plan view (see the dashed lines in Figure 2), an oblong shape substantially of the same width as the diameter of the extension 14 and oriented in a radial direction so as to allow a radial guided translation of the ring 10 when the latter is in a first axial position, called position "unscrewed" ( Figures 3A, 3B), as will appear in the following.
  • the connecting mechanism 11 connecting the ring 10 to the movement 6 comprises a rectangle-shaped and movable rectangular parallelepiped return cage 20 in translation in the aforementioned radial direction, a crown rod generally cylindrical 21, of the same axis as the ring 10 and cooperating with a distal distal portion 22 of the crown extension 14, and a stem of control 23 extending in the plane of the movement 6 and in the radial direction supra.
  • the diameter of the through bore 33 of the upper wall of the cage 20 is slightly greater than the diameter of the portion of the rod 21 passing through this bore 33, of so that the crown rod 21 and the return cage 20 are integral in translation in the aforementioned radial direction while allowing the rod to 21 to turn freely relative to the return shaft 20.
  • a seal ring 36 disposed in the bore 33 seals between the rod of crown 21 and the return cage 20.
  • the part distal distal 22 of the crown extension 14 is engaged in a hole axial blind 37 formed in the crown rod 21.
  • This distal portion 22 has external coupling means 38 which mate with corresponding internal coupling means 39 of the crown rod 21 for securing in rotation the crown 10 and the crown rod 21 when the 10 is in unscrewed axial position (FIGS. 3A and 4A), and which uncouple from these coupling means 39 to disengage in rotation the crown 10 and the crown rod 21 (FIG. 4B) when the crown 10 is thrust axially from its unscrewed position shown in Figures 3A and 4A.
  • the coupling means 38, 39 are for example respective parts of the crown extension 14 and crown rod 21 with polygonal section.
  • the ring 10 is subjected to the action of a spring of compression 40 mounted between the crown extension 14 and the bottom of the hole blind 37 and guided in a blind hole 41 of the crown extension 14, and an annular internal abutment 42 of the crown rod 21 prevents the crown 10 completely out of the blind hole 37 by axially locking the means coupling 38.
  • the crown 10 can occupy a axial position screwed, position in which the crown head 13 is screwed around the crown tube 16 and the ring 10 is uncoupled from the stem of crown 21 ( Figures 1 and 4B).
  • This screwed position is an inactive position, rest, making it possible to increase the tightness of the watch by compressing the attached 19.
  • the crown 10 can be moved radially towards the periphery of the watch case until reach a stable second radial position, shown in Figure 3B, off-center relative to the crown tube 16.
  • the crown 10 drives with it the connecting mechanism 11, namely the crown rod 21, the return cage 20 and the control rod 23.
  • a rotation of the crown 10 by the user controls the setting time of the watch by driving the control rod 23.
  • the user brings back the entire crown 10 - mechanism link 11 in its first radial position, where the crown 10 is found centered with respect to the threaded outer surface 18 of the crown tube 16.
  • the present invention is not limited to winding and setting the time. It goes without saying that the crown 10 of the invention could be used to control other functions, such as setting functions a separate date display mechanism or integrated with the movement well said. In one variant, one of the two radial positions of the crown 10 could be an inactive position, in which the rotation of the crown does not activate any particular function in the watch. Finally, if this is desired, more than two stable radial positions could be expected for the crown 10.
  • crown 10 could be arranged elsewhere than on the upper face of the watch case, for example on the underside or even on the edge of this box. In the latter case, the lateral translation of the crown 10 could be parallel to the control rod 23 and in the plane of movement 6.
