Abstract

L'escabeau comporte une série de marches pivotantes (40) et une plate-forme supérieure (38) articulée entre les deux cadres (10, 12). Chacune des marches (40) est articulée à sa partie postérieure, aux montants (14) du cadre antérieur (10) autour d'un axe de pivotement (48) situé en arrière par rapport à un barreau d'appui (16). Une tringle (50) est disposée le long de la face intérieure d'un des montants (14) et est reliée aux marches (40) par des articulations (52) situées entre les axes de pivote­ ment (48) et les barreaux (16). La tringle (54) est reliée à la plate­ forme (38) par une bielle (62). Lorsqu'on fait passer les deux cadres (10, 12) de la position écartée d'utilisation à la position aplatie de rangement, les marches (40) et la plate-forme (38) pivotent à l'unisson, grâce à la tringle d'accouplement (50), en passant de la position horizontale à une position escamotée entre les montants (14) du cadre antérieur (10), et inversement. Lorsque les marches (40) sont horizontales, leurs parties anté­ rieures prennent appui sur les barreaux (16). The stepladder has a series of pivoting steps (40) and an upper platform (38) articulated between the two frames (10, 12). Each of the steps (40) is articulated at its part posterior, to the uprights (14) of the anterior frame (10) around a pivot axis (48) located behind a support bar (16). A rod (50) is arranged along the inner face of one of the uprights (14) and is connected to the steps (40) by joints (52) located between the pivot axes ment (48) and the bars (16). The rod (54) is connected to the plate form (38) by a connecting rod (62). When we pass the two frames (10, 12) from the spread apart position to the position flat storage, the steps (40) and the platform (38) pivot in unison, thanks to the coupling rod (50), in moving from the horizontal position to a retracted position between the uprights (14) of the front frame (10), and vice versa. When the steps (40) are horizontal, their parts ante are supported on the bars (16).
