Abstract

L'invention concerne un ensemble bande de mesure à être utilisé dans un ascenseur, pour déterminer une position absolue d'une cabine d'ascenseur le long d'un trajet de déplacement. L'ensemble bande de mesure (41) comprend une bande de mesure (23) destinée à être agencée le long du trajet de déplacement, des informations d'emplacement variables étant enregistrées le long de la bande de mesure (23), à l'aide desquelles une position actuelle par rapport à la bande de mesure (23) peut être déterminée, ainsi qu'un dispositif de fixation (39) destiné à être agencé à une extrémité supérieure du trajet de déplacement, destiné à fixer la bande de mesure (23) sur une structure de maintien (43) à une position fixe par rapport au trajet de déplacement. Le dispositif de fixation (39) comprend un dispositif d'encliquetage (49) au moins en deux parties, doté d'un premier élément d'encliquetage (45) et d'un second élément d'encliquetage (47). Le premier élément d'encliquetage (45) est fixé solidement à la bande de mesure (23). Le second élément d'encliquetage (47) est destiné à être monté solidement sur la structure de maintien (43). Le dispositif d'encliquetage (49) est conçu de façon à ce que les premier et second éléments d'encliquetage (45, 47) puissent être reliés entre eux mécaniquement, de façon réversible, et puissent être désaccouplés l'un de l'autre, et de façon à ce que les premier élément et second éléments d'encliquetage (45, 47) se désaccouplent automatiquement lors de l'apparition d'une force agissant sur le premier élément d'encliquetage (45) et orientée à l'opposé du second élément d'encliquetage (47), qui dépasse une force de valeur limite prédéfinie. De ce fait, l'invention permet d'éviter, entre autres lors de l'application d'une force sur la bande de mesure (23), un endommagement de la bande de mesure (23) ou de la structure de maintien (43).
