Abstract
(EN)
A foldable step steel (10) includes a frame 12 having front and rear legs (14, 16) and top, middle, and bottom steps (34, 36, 38). A central step link (40) is coupled to the rear portion of each step (34, 36, 38) to support the steps when step stool (10) is unfolded and to control pivoting movement of the steps relative to front leg (14) during folding of step stool (10). A releasable latch (22) is coupled to a rear portion of top step (34) and configured to engage an upper cross strut (180) included in rear leg (16) to retain step stool (10) in an unfolded use position.
(FR)
La présente invention concerne un tabouret-escabeau pliant (10) comprenant une structure (12) avec des pieds avant et arrière (14, 16), et des marches supérieure, centrale et inférieure (34, 36, 38). Un élément d'articulation central (40) est fixé à la partie arrière de chaque marche (34, 36, 38) afin de servir de support à celles-ci lorsque le tabouret-escabeau (10) est déplié et afin de commander le mouvement de rotation des marches par rapport au pied avant (14) lors du pliage du tabouret-escabeau (10). Un verrou (22) est fixé sur la partie arrière de la marche supérieure (34) et conçu de manière à pénétrer dans une entretoise croisée supérieure (180) située dans le pied arrière (16) pour maintenir le tabouret-escabeau (10) en position d'utilisation dépliée.
