Abstract

L'invention concerne un poteau de garde-corps (10.1) pour un échafaudage (50) comprenant des étages d'échafaudage (52, 54), des barres verticales (58.1) avec un premier dispositif de raccordement (12.1), un deuxième dispositif de raccordement (16), un troisième dispositif de raccordement (18), le deuxième dispositif de raccordement (14) présentant une première unité d'engagement par correspondance géométrique (24) raccordée fixement au poteau de garde-corps (10.1) et une unité d'engagement par correspondance géométrique déplaçable (26), qui peut être déplacée d'une position de fermeture dans une position d'ouverture maximale et inversement, un blocage par engagement par correspondance géométrique d'un poteau de garde-corps inséré (10.1) sur une barre verticale (58.1) de l'échafaudage (50) étant réalisé dans la position de fermeture, caractérisé en ce que l'unité d'engagement par correspondance géométrique déplaçable (26) est raccordée à un arbre (18) rotatif actionnable, un élément élastique (28) est prévu, lequel agit sur l'unité d'engagement par correspondance géométrique déplaçable (26) et la retient dans la position de fermeture sous l'effet de sa seule action, l'unité d'engagement par correspondance géométrique déplaçable (26), dans sa région d'extrémité frontale, est réalisée de telle sorte qu'elle s'ouvre d'abord dans la direction d'ouverture lors de l'application d'une pression sur une barre verticale (58.1) de l'échafaudage (50) et après dépassement d'une position prédéfinissable/déplacement de la barre verticale (58.1), c'est-à-dire à l'obtention de la position d'ouverture maximale, se déplace sous l'effet de l'action de la force de ressort de l'élément élastique (28) dans la position de fermeture et entoure et bloque ainsi fermement la barre verticale (58.1) au moins en partie par engagement par correspondance géométrique.
