  • the teeth from both sets preferably have the same dimensions.
  • the carriage of the operating bar 10 is then, by analogy, provided with two gear racks whose teeth are shifted along the pitch line(s) and wherein each set of teeth of the drive gear 7 engages with one of the aforementioned gear racks, wherein at least one tooth of the one set and one tooth of the other set engage simultaneously in the one rack and the other gear rack, respectively.
  • Both sets of teeth may be separated from each other by a rib on the gear wheel 7, which rib is slidable in a groove provided to that end between the gear racks.
  • gear wheel 7 contains two sets of seven teeth
  • fourteen tooth transitions can thus be achieved, all in such a way as to ensure a smoother movement of the carriage.
  • the number of teeth per set can be reduced, so that the teeth can be made larger and more solid while still allowing a smooth movement.
  • three or more sets of teeth may also be provided in the gear wheel 7 which in that case cooperate with the respective tooth racks 11 on the carriage of the operating bar 10.

Abstract

L'invention concerne une serrure encastrée à mécanisme d'actionnement destinée à des lattes de fermeture d'une fenêtre ou d'une porte. Le mécanisme comprend un boîtier, une barre d'actionnement et une transmission par engrenage pour entraîner la barre d'actionnement. L'invention concerne également une roue dentée pouvant être entraînée en rotation au moyen d'une poignée, la barre d'actionnement comprenant un chariot pourvu d'une crémaillère coopérant avec la roue dentée pour déplacer le chariot dans le boîtier. Le rapport d'engrenage entre la roue dentée et le chariot est variable ; l'axe de la roue dentée est décentré ; la roue dentée comporte deux rayons identiques à 0° et 180°, un rayon le plus court entre 180° et 360° et un rayon le plus grand entre 0° et 180° de rotation de la roue dentée ; la roue dentée est soumise à une rotation de 180° +/- 5° maximum ; et la crémaillère (11) présente une forme complémentaire à la rotation de 180° de la roue dentée.
