Abstract

Soutènement marchant, caractérisé en ce que les cadres qui s'appuient sur la semelle, par l'intermédiaire de montants, à longueur variable 63, 64, sont reliés entre eux à l'intérieur des éléments jumelés 1 par plusieurs rails de guidage 29 aménagés au-dessus des éléments télescopiques des montants 65,66, que chaque rail de guidage 29 est relié fixement par une articulation horizontale 30 à l'une des unités 2 et coulisse dans le sens longitudinal du rail 29 sur l'autre de ces unités 3 et que les parties mobiles de pistons pousseurs qui agissent dans le sens vertical sur les rails de guidage 29 s'appuient sur les extrémités libres 35, 35' de ces rails 29 et plus précisément au-delà des articulations 30, voire au-delà des glissieres 49, 50.Walking support, characterized in that the frames which rest on the sole, by means of uprights, of variable length 63, 64, are connected to each other inside the twin elements 1 by several guide rails 29 arranged above the telescopic elements of the uprights 65,66, that each guide rail 29 is fixedly connected by a horizontal articulation 30 to one of the units 2 and slides in the longitudinal direction of the rail 29 on the other of these units 3 and that the movable parts of pushing pistons which act in the vertical direction on the guide rails 29 bear on the free ends 35, 35 'of these rails 29 and more precisely beyond the joints 30, or even beyond the slides 49, 50.
