  • the latching element 41 is pressed into the step element 42 by at least one spring element 43, for example a spring washer supported against the first housing part 15.
  • the second wheel 52 designed as a ten-beam star wheel, and the stepping mechanism 40 are shown in detail.

  • 40 and 41 show an alternative embodiment of a stepping mechanism 40, wherein the locking element 41 is formed by a ball which is pressed by the spring element 43 into a stepping element 42 formed by a recess in an end face of the second wheel 52, for example.
  • Reference numeral 44 denotes an axial blind bore in which the spring element 43 and the locking element 41 are arranged.

Abstract

L'invention concerne un dispositif (10) de comptage et de calcul, en particulier avec des nombres décimaux, comprenant : au moins un cadran (11, 12) ayant des nombres disposés les uns derrière les autres le long d'une courbe, commençant par un nombre de départ et se terminant par un nombre final ; et au moins deux éléments de pointeur (21, 22) montés de manière rotative, qui peuvent être déplacés dans le sens horaire ou antihoraire sensiblement indépendamment l'un de l'autre, au moins deux éléments de pointeur (21, 22) étant montés pour une rotation autour du même pivot (21a) et appartenant à un cadran commun (11). Afin de simuler et de mettre en évidence un système de numération dénominationnel mathématique de manière aussi simple et claire que possible, le dispositif (10) comprend un mécanisme à étapes (40) qui est conçu pour déplacer au moins un élément de pointeur (21, 22) par étapes, chaque étape étant associée à un nombre, et un élément de pointeur des au moins deux éléments de pointeur (21, 22) étant un élément de pointeur d'entraînement et un autre élément de pointeur des au moins deux éléments de pointeur (21, 22) étant un élément de pointeur entraîné, et le dispositif (10) comprenant un mécanisme d'entraînement qui est conçu pour déplacer l'élément de pointeur entraîné au moyen de l'élément de pointeur d'entraînement par une étape s'il existe un événement de déclenchement, l'événement de déclenchement étant défini par l'élément de pointeur d'entraînement passant par le nombre de départ ou le nombre final.
