Title
(EN) LINEAR TELESCOPIC ACTUATOR FOR MOVING A FIRST AND A SECOND ELEMENT RELATIVE TO A STATIONARY ELEMENT
(FR) ACTIONNEUR LINÉAIRE TÉLESCOPIQUE POUR DÉPLACER UN PREMIER ET UN SECOND ÉLÉMENTS RELATIVEMENT À UN ÉLÉMENT FIXE
Abstract
(EN)
The invention relates to a linear telescopic actuator for moving a first (10b) and a second (10a) element relative to a stationary element (102). Said actuator comprises a base (101) that is to be connected to the stationary element (102) and is used as a cavity for a first rotationally locked rod (106) which can be translated by a drive shaft (104) that is to be connected to rotational driving means (107). One end (108) of said first rod is to be connected to the first element that is to be moved. The actuator is characterized in that the first rod (106) supports a second rod (117) which is aligned therewith and one end (118) of which is to be connected to the second element that is to be moved. Said second rod (117) can be rotationally locked and can be translated by a second drive shaft (112, 115) which extends through the base and is connected to rotational driving means (113, 111).

La présente invention se rapporte à un actionneur linéaire télescopique pour déplacer un premier (10b) et un second (10a) éléments relativement à un élément fixe (102), comprenant une base (101), destinée à être rattachée à l'élément fixe (102), et servant de logement à une première tige (106) bloquée en rotation et apte à être entraînée en translation par l'intermédiaire d'un arbre (104) d' entraînement destiné à être relié à des moyens d' entraînement (107) en rotation, la première tige étant destinée à être rattachée par une extrémité (108) au premier élément à déplacer, caractérisé en ce que la première tige (106) supporte deuxième tige (117) disposée dans le prolongement de celle-ci et destinée à être rattachée par une extrémité (118) au deuxième élément à déplacer, ladite deuxième tige (117) étant apte à être bloquée en rotation et entraînée en translation par l'intermédiaire d'un deuxième arbre d' entraînement (112, 115) traversant la base et relié à des moyens d' entraînement en rotation (113, 111).
