Abstract

L'invention concerne un chevalet de travail (1) et en particulier un chevalet de sciage qui présente une articulation de pivotement (13), au moins deux jambes de soutien (3, 5) s'étendant de l'articulation de pivotement et qui peuvent être inclinées l'une par rapport à l'autre par l'articulation de pivotement dans une position du chevalet de travail qui permet une pose stable du chevalet de travail sur un soubassement de pose, et un dispositif de fixation (21) qui bloque au moins le déploiement des jambes de soutien hors de la position du chevalet de travail. Au moins une des jambes de soutien peut pivoter hors de la position du chevalet de travail autour de l'articulation de pivotement par rapport à l'autre jambe de soutien, essentiellement jusque dans la position horizontale dans laquelle la jambe de soutien déployée peut être déposée sur un appui plus haut que le soubassement de pose et peut en particulier y être fixée.
