Abstract

L'invention concerne un tréteau destiné à être fixé sur une plateforme de travail à orientation horizontale. Ce tréteau présente deux montants (21,23) inclinés l'un vers l'autre et comprenant deux premiers éléments tubulaires (20, 22) et deux seconds éléments tubulaires (24, 26), un premier élément tubulaire et un second élément tubulaire s'emboîtant l'un dans l'autre et pouvant coulisser axialement l'un par rapport à l'autre pour modifier la longueur du montant. L'objet de l'invention est de pouvoir régler en hauteur le tréteau ou la plateforme de travail de manière simple et fiable, et d'éviter que le second élément tubulaire ne sorte de manière accidentelle du premier élément tubulaire. A cet effet, les seconds éléments tubulaires (24, 26) coopèrent avec une traverse (32). La traverse (32) comprend deux fentes longitudinales (38, 40) présentant chacune une butée extérieure (42, 44); une partie (36) d'un second élément tubulaire (24, 26), ou un élément s'étendant à partir de ce dernier, s'emboîte dans une fente longitudinale (38, 40) de sorte que, lors du déplacement du second élément tubulaire (24, 26) par rapport au premier élément tubulaire (20, 22), cette partie (36), ou cet élément, peut coulisser dans la fente longitudinale (38, 40) associée, dans le sens longitudinal de ladite fente. Lorsque ladite partie (34, 36) ou ledit élément repose contre la butée extérieure (42, 44), le premier élément tubulaire (20, 22) et le second élément tubulaire (24, 26) sont en prise.
