(EN) FOLDING FRAME
(FR) STRUCTURE PLIABLE
Abstract
(EN)
A mobile frame for supporting ground working tools. The mobile frame comprises a longitudinal member (11) and two first pivotal boom sections (17) one to each side of the longitudinal member. A first pivot means (19) connects each first boom section (17) to the longitudinal member (11) for pivotal movement about a respective vertical axis between a first position in which each boom extends outwardly of the longitudinal member and a second position in which the boom sections are located substantially alongside the longitudinal member. The frame further comprises a pair of pivotal first support beams (27) one extending between each first boom section and the longitudinal member. Each support beam (27) and the respective first boom section (17) are interconnected for pivotal movement about a vertical axis. A second pivot means (31) connects the support beams (27) to the longitudinal member (11) for pivotal movement about respective vertical axes. A power device or other means is provided for effecting relative movement between the first pivot means and the second pivot means along the axis of the longitudinal member thereby to effect pivotal movement of the boom sections between the first and second positions.
(FR)
Une structure mobile, destinée à soutenir des outils de travail de la terre, comprend un élément longitudinal (11) et deux premières sections de flèche pivotantes (17), l'une de chaque côté de l'élément longitudinal. Un premier organe de pivot (19) relie chaque première section de flèche (17) à l'élément longitudinal en vue d'un mouvement de pivot autour d'un axe vertical correspondant entre une première position dans laquelle chaque flèche s'étend vers l'extérieur par rapport à l'élément longitudinal et une seconde position dans laquelle les sections de flèche sont disposées essentiellement le long de l'élément longitudinal. Ladite structure comprend en outre une paire de premières poutrelles de support pivotantes (27) l'une et l'autre s'étendant entre chaque première section de flèche et l'élément longitudinal. Chaque poutrelle de support (27) et la première section de flèche correspondante (17) sont reliées entre elles en vue d'un mouvement de pivot autour d'un axe vertical. Un second organe de pivot (31) relie les poutrelles de support (27) à l'élément longitudinal (11) en vue d'un mouvement de pivot autour d'axes verticaux correspondants. Un dispositif de transmission mécanique ou autre organe similaire est prévu pour effectuer le mouvement relatif entre le premier organe de pivot et le second organe de pivot le long de l'axe de l'élément longitudinal, permettant ainsi un mouvement de pivot des sections de flèche entre la première et la seconde position.
