Abstract
Etai téléscopique pour deux objets pouvant être pliés l'un par raport à l'autre, notamment pour supporter une surface de travail (1) pouvant être pliée par rapport à une structure de bâti (2, 5). L'étai (4) comporte deux tubes (6, 7) qui s'insèrent l'un dans l'autre et sont destinés à un raccordement par pivotement, au niveau de leurs extrémités opposées, à une extrémité respective desdits objets, et comprend d'autre part un tube de guidage intérieur (8) agencé dans les tubes téléscopiques, un ressort de tension (15) qui s'étend axialement sur toute la longueur des tubes, et un moyen de verrouillage (9, 10) permettant de verrouiller de manière libérable les tubes téléscopiques dans une position donnée l'un par rapport à l'autre. En vue de faciliter la fixation de l'étai (4), le tube de guidage intérieur (8) est fixé axialement par rapport à un tube téléscopique (6) et accompagne le mouvement de ce tube par rapport à l'autre tube téléscopique (7). Dans le but d'amortir les oscillations entre les objets pliables, lorsque l'étai est en position rétractée, les extrémités du ressort de tension (15) sont chacune fixées par rapport à leur tube téléscopique respectif (6, 7), et la longueur du ressort de tension permet à ce dernier de pousser constamment au téléscopage des tubes.Telescopic strut for two objects which can be folded relative to one another, in particular for supporting a work surface (1) which can be folded relative to a frame structure (2, 5). The forestay (4) comprises two tubes (6, 7) which fit into one another and are intended for connection by pivoting, at their opposite ends, to a respective end of said objects, and comprises on the other hand an inner guide tube (8) arranged in the telescopic tubes, a tension spring (15) which extends axially over the entire length of the tubes, and a locking means (9, 10) for locking releasably the telescopic tubes in a given position relative to each other. In order to facilitate the fixing of the forestay (4), the inner guide tube (8) is fixed axially with respect to a telescopic tube (6) and accompanies the movement of this tube with respect to the other telescopic tube ( 7). In order to dampen the oscillations between the foldable objects, when the forestay is in the retracted position, the ends of the tension spring (15) are each fixed relative to their respective telescopic tube (6, 7), and the length of the tension spring allows the latter to constantly push the telescoping of the tubes.
