This invention provides an adjustable length member (100) for fitment to a variety of apparatus including ladders. The preferred form provides two members (1, 2) contained in sliding contact one of which (2) has a taper or sloped surface. The members pass through a constriction (3) and a member (21) adjacent, such as a wedge or camming device may be used to adjust the constriction to limit the passage of the tapered member through the constriction.
Cette invention concerne un élément à longueur réglable (100) destiné à s'adapter sur un certain nombre d'appareils au nombre desquels des échelles. Le mode de réalisation préféré comporte deux éléments (1, 2) coulissant l'un sur l'autre, l'un d'entre eux ayant une surface effilé ou inclinée. Les éléments traversent un étranglement (3) et il est possible d'utiliser un élément adjacent (21), un coin ou dispositif à came par exemple, pour moduler la taille de l'étranglement afin de restreindre les possibilités de passage de l'élément effilé dans ledit étranglement.
