A tooth engaging member (25) is pivotally secured to the sleeve (21) and has a tooth engaging head (26) biased against the toothed edge (23) inside the sleeve (21) for supporting the sleeve about the support rod (22) while permitting upward displacement of the sleeve about the rod. The tooth engaging member (25) can be unbiased from the toothed edge (23) of the support rod (22) to permit downward displacement of the sleeve (21) about the rod (22). A locking member (40) is provided to lock the tooth engaging member (25) in arresting position with the toothed edge (23). The sleeve (21) is also provided with a connector (52) for support engagement with one of the corner frame members (11) of the scaffolding (10).
L'invention concerne un échafaudage (10) réglable et transportable, qui comprend un mécanisme (20) de support de montants réglable destiné à un échafaudage à éléments d'angle de châssis (11) verticaux reliés à des éléments de châssis (12) horizontaux et des traverses (13). Le mécanisme (20) comprend un manchon (21) ouvert aux extrémités destiné à loger une tige de support (22) le traversant, ladite tige ayant au moins une section bord denté (23) qui se fixe à un pied de support inférieur (24). Un élément de prise à dent (25), fixé pivotant au manchon (21), est doté d'une tête de prise dentée (26) sollicitée contre le bord denté (23) à l'intérieur du manchon afin de supporter ledit manchon autour de la tige de support (22) tout en permettant le déplacement vers le haut du manchon (21) autour de la tige (22). L'élément de prise à dent (25) peut être non sollicité du bord denté (23) de la tige de support (22), ce qui permet le déplacement vers le bas du manchon (21) autour de ladite tige (22). Un élément de blocage (40) permet de verrouiller l'élément de prise à dent (25) en position de blocage avec le bord denté (23). Le manchon (21) est également doté d'un connecteur (52) permettant une mise en prise avec l'un des éléments d'angle de châssis (11) de l'échafaudage (10).
