Definitions

  • the present invention relates to devices for correcting the time information displayed by an electronic watch, and it relates more precisely to electronic watches in which the different operating and correction modes are called up by means of a crown capable of being manipulated by two-way rotation.
  • crown is spreading very widely at present, not only for aesthetic reasons, but especially with the aim of facilitating the access of the user of the watch to these different modes, by offering him manipulations similar to those known for conventional mechanical watches for example for setting the time, day or month.
  • one of the objects of the invention is to propose a correction device by which two different types of correction of the displayed information can be carried out in the same axial position of the crown, the direction of the corrections being determined by the direction of rotation of the crown.
  • one of the essential characteristics of the invention is to provide, in the correction device, means for detecting any reversal of the direction of rotation of the crown after the completion of a first type of correction, and for then order, in response to this detection, the stopping of this first type of correction and the implementation of a second type of correction.
  • the reference 60 shows the time base of an electronic watch, the pulses of which supply the circuit 61 for controlling the stepping motor 62 which causes an analog display, not shown.
  • Time zone corrections are made by means of a crown associated with a contact mechanism 1, 2 so that contact 1 is periodically closed when the crown is rotated clockwise, contact 2 being periodically closed when the crown is operated in the opposite direction.
  • a mechanism is known per se and described for example in French patent application No. 77 06198.
  • Each pulse corresponding to the closing of contact 1 is used, as will be seen below, to trigger either an advance circuit 41 in steps of 1 hour, or an advance circuit 51 in steps of only one hour.
  • These advance circuits 41 and 51, as well as the delay circuits 42 and 52 have been represented by separate blocks of the control circuit 61 of the motor 62, but it is clear that they can be an integral part of this circuit. Their function is to influence the control means of the motor 62 so as to cause the latter to carry out a determined number of steps ra pides, forward or backward, corresponding to a correction of 1 hour or 1 ⁇ 2 hour of the displayed time.
  • the closing pulses of contact 2 selectively trigger the delay circuits 42 or 52 depending on the type of correction desired.
  • a contact 3 or any other means is actuated when the correction means are put into action, for example when the rod is pulled to put it in an axial position reserved for time zone changes.
  • Such a circuit comprises for example a bistable rocker 11, respectively 12, capable of being brought into the high position by closing the contact 1, respectively 2.
  • the advance circuit 41 respectively delay 42, in steps of 1 hour, is controlled via an AND gate 21, respectively 22, with two inputs, one of which is connected directly to contact 1, respectively 2, and the other, via an inverter circuit at the output of the flip-flop 12, respectively 11. It follows that the advance or delay circuits 41 or 42 will not be controlled by their respective contact 1 or 2 only if the other contact has not yet been operated (no reversal of the direction of rotation).
  • the advance circuit 51 respectively delay 52, in steps of 1 ⁇ 2 hour, is controlled by an AND gate 31, respectively 32, with two inputs, one of which is connected directly to the contact l, respectively 2, and the other at the output of the flip-flop 12, respectively 11. It follows that the advance or delay circuits 51 or 52 can only be controlled by their respective contact 1 or 2 if the other con tact has already been operated (reversing the direction of rotation).
  • the time zone changes are obtained in the position pulled from the crown, but they could as well be carried out in the neutral position of this crown, after actuation of a second control member (push-button, key capacitive, file, etc.). It would then suffice to provide that the actuation of this second control member simultaneously causes the reset of the flip-flops.
  • a second control member push-button, key capacitive, file, etc.
