Definitions

  • the invention relates to a blocking device for winding crowns of watches.
  • Wrist and pocket watches have a winding crown, which usually also serves to set the time and date.
  • This setting function is activated by, for example, pulling the crown out axially and pushing it in again after adjustment.
  • the invention has for its object to provide a way as the winding crown of a clock can be blocked so that they can not accidentally get into the adjustment function under any circumstances.
  • Show it 1 is a plan view of an elevator crown and a bridge on which the crown is arranged,
  • a crown assembly 1 is arranged on a bridge 2, which is mounted on the outside of a watch case (not shown).
  • the axis of the crown assembly 1 is offset from the median plane of the bridge, towards the underside of the clock.
  • crown assembly consists of two crowns, of which the upper is the actual winding crown 3. Under the bridge 2 and between the bridge and the housing another, designated as locking crown 4 crown is arranged.
  • the winding crown 3 is connected to the elevator drive 5 in the usual way.
  • the winding crown On its underside facing the bridge, the winding crown has a concentric annular groove 6 in which an annular collar 7 formed on the bridge engages.
  • the lateral surface 8 of the crown is provided in the usual way with axially parallel grooves 9 for better tangibility of the crown.
  • a press-fit 10 is provided for the implementation of the elevator drive 5 through the housing .
  • a sealing element 11 is arranged, which seals the elevator drive in any position. The watch is therefore watertight even when the lift drive is pulled out.
  • the locking crown 4 essentially has a section 13 engaging in a bore 12 of the bridge with a cylindrical outer surface and a subsequent, housing-side section 14 whose lateral surface 15 is provided with grooves 16 like that of the winding crown.
  • the bore 12 in the bridge is arranged eccentrically with respect to the axis of the winding crown.
  • the engaging into the bore of the bridge portion 13 of the locking crown to its lower portion 14 and the lateral surface 15 is offset eccentrically.
  • a bore 17 through which the elevator drive extends. This bore is concentric with the portion 14 engaging the bore 12 of the bridge and thus eccentric therefrom, as with the axis of the winding crown.
  • a projection 18 is arranged, which is a circumferential groove 19 opposite the elevator drive in the same axial position.
  • the projection 18 engages in the groove 19 in certain angular positions of the locking crown, as shown in FIG. 3, while in other angular positions, as shown in FIG. 4, does not engage in the groove.
  • the elevator drive can not be pulled out and thus no time or date setting is made. In this position of the elevator drive only the winding of the clock is possible. Conversely, the withdrawal of the elevator drive and the adjustment is possible if the projection does not engage in the groove.
  • the optimal angular positions are the two extreme positions of the eccentricity offset by 180 °.
  • a defined locking mechanism is provided.
  • the locking crown has on its underside facing the housing two recesses 20, in which two arranged in the housing locking cylinder 21 can engage with resiliently mounted balls.
  • the locking cylinder 21 are in the two intended extreme positions of the eccentricity in the wells in engagement.
  • the locking crown In order to release the lock or to reactivate it after setting, the locking crown is rotated in any direction by 180 ° until the locking cylinder 21 in turn engage in the recesses 20. In one condition, the crown is free for setting time and date. After completing the adjustment, the locking crown is returned to the locked position by turning it 180 °.
  • a window 22 is attached, through which a suitable marking is visible and indicates the respective state.
  • This marking for example a color marking, is attached to the cylindrical outer wall of the bridge-engaging portion 14 of the locking crown.
  • the locking of the locking cylinder is audible.

Abstract

La commande du remontoir d'une montre est dotée d'un dispositif de blocage, afin d'éviter un changement involontaire de l'heure et de la date. Ce dispositif de blocage comprend un mécanisme de verrouillage qui bloque dans l'axe la commande du remontoir (5) au moyen d'une couronne de blocage (4). Dans des positions angulaires définies, des cylindres de blocage (21) se mettent en prise dans des évidements (20) de la couronne de blocage.
