Definitions

  • the balance of forces may be such that the action exerted by the user on the control pusher becomes lower than the reaction of the various mechanical elements operated under the effect of this action.
  • the action of the user becomes inoperative and the meters come to rest in a non-controllable position. Therefore, anything that can contribute to a decrease in the reaction forces opposed by the chronograph mechanism when controlling it must be examined. For this purpose, it is of the greatest interest to seek to reduce the friction forces that oppose the movement of the lever with two hammers.
  • the present invention relates to a timepiece device for simultaneously resetting two time counters, in particular for a chronograph mechanism. according to claim 1.
  • the present invention essentially relates to a new design of an instantaneous reset mechanism comprising a two-hammer lever and that such a mechanism can equally well be used in a chronograph mechanism with two time counters. in any other time counter mechanism comprising two display devices (minute and second for example) to be reset simultaneously using a control lever or reset.

Claims (5)

  1. Vorrichtung für eine Uhr zum gleichzeitigen Zurücksetzen zweier Zeitmesser, insbesondere für einen Chronographenmechanismus, wobei die zwei Zeitmesser um eine mit einer Kurvenscheibe (6b, 8b) verbundenen Achse schwenkbar sind und wobei die Vorrichtung zum gleichzeitigen Zurücksetzen (1) einen mit zwei Hämmer (6, 8) versehenen Hebel (4) aufweist, die zum Anschlagen gegen die entsprechenden Kurvenscheiben (6b, 8b) während dem Zurücksetzen der beiden Zeitmesser ausgebildet sind, zumindest ein Sperrstift (10, 12) zum Führen des mit zwei Hämmer (6, 8) aufweisende Hebels (4), der mit dem Hebel (4) verbunden und dazu ausgebildet ist, sich in einer Formöffnung (24, 26) zu bewegen, die in einer Brücke (28) ausgebildet ist, dadurch gekennzeichnet, dass ein Fingerring (16a; 16b, 16c) frei drehbar um den Sperrstift (10, 12) gelagert ist und sich zwischen dem Sperrstift (10, 12) und der Formöffnung (24, 26) erstreckt, in welcher er sich bewegt.
  2. Vorrichtung für eine Uhr nach Anspruch 1, dadurch gekennzeichnet, dass der zwei Hämmer (6, 8) aufweisende Hebel (4) von zwei Sperrstiften (10, 12) geführt ist, die mit dem Hebel (4) verbunden sind und die jeweils dazu ausgebildet sind, sich in einer Formöffnung (24, 26) zu bewegen, die in der Brücke (28) ausgebildet ist, wobei einer der Sperrstifte (10) eine Schwenkkopplung zwischen dem Hebel (4) mit zwei Hämmer (6, 8) und einem Rücksetzhebel (2) ermöglicht, auf welchen ein Benutzer einwirken kann, um die Kurvenscheiben (6b, 8b) in eine Winkelstellung zu bringen, die einer Rücksetzposition der Zeitmesser entspricht.
  3. Vorrichtung für eine Uhr nach Anspruch 2, dadurch gekennzeichnet, dass der Sperrstift (10) über welchen der Hebel (4) mit zwei Hämmer (4, 6) mit dem Rücksetzhebel (2) verbunden ist, einen Fingerring (16a) trägt, während der andere Sperrstift (12) zwei Fingerringe (16b, 16c) übereinander trägt, von denen der untere (16c) die Rolle eines dicken Keils spielt, um die Dicke des Rücksetzhebels (2) zu kompensieren.
  4. Vorrichtung für eine Uhr nach einem der vorhergehenden Ansprüche 1 bis 3, dadurch gekennzeichnet, dass der Fingerring (16a, 16b, 16c) ein gedreht Metallstück oder ein Stein ist.
  5. Vorrichtung für eine Uhr nach Anspruch 4, dadurch gekennzeichnet, dass der Stein ein Rubin ist.
