Abstract

L'invention concerne une main courante, en particulier pour des ouvrages d'échafaudage, tels que par exemple des ouvrage d'échafaudage d'escalier. La main courante comporte au moins deux segments (28, 30, 32) reliés l'un à l'autre par une unité (34, 36) de liaison de manière à obtenir une main courante (26) continue. Au moins un organe de fixation (38) de main courante destiné à fixer le segment (28, 30, 32) de la main courante à un élément d'échafaudage (12, 14, 16) est fixé à au moins l'un des segments (28, 30, 32) de main courante. L'unité (34, 36) de liaison comporte deux éléments (42, 44) de liaison pouvant pivoter autour d'un axe de pivotement (S) l'un par rapport à l'autre. Au moins un, de préférence chaque élément de liaison (42, 44) est relié ou peut être relié à l'un des segments (28, 30, 32) de main courante reliés l'un à l'autre par l'unité de liaison (34, 36) de manière à pouvoir tourner autour d'un axe de rotation (D1, D2) non perpendiculaire et non parallèle à l'axe de pivotement (S).
