Title
(EN) LADDER COMBINED WITH THREE DIFFERENT TRANSPORT FUNCTIONS
(FR) ECHELLE COMBINEE A TROIS FONCTIONS DE TRANSPORT
Abstract
(EN)
A ladder combined with three different transport functions which can be transformed into a trestle ladder, a long ladder, a sack truck and a vehicle to be used by craftsmen and storemen needing a simple assembly for many purposes. Two ladder sides (4 and 5) are held together in two pivotal joints (1 and 2) on the uppermost step (3) and are pivotally journalled about the axis of rotation S1, which can be locked by means of a biased clamp (12) secured to a locking piston. A blade (8) is hinged to the rear lowermost step and can also be used for securing the two ladder sides by virtue of its shape which can fasten the front lowermost step, and by means of a locking mechanism provided with a biased rocker arm (9) which presses the head of the rocker arm into one of two openings so as to fasten the blade along the ladder side or at an angle of 90°. The wheels can also be locked along the ladder sides and at an angle of 90° opposite the blade by means of a locking mechanism placed on a sleeve of the wheel suspension, said sleeve acting in the same manner as the locking means (9) with a biased rocker arm, (9a) of the blade. An additional wheel is mounted on the uppermost step and renders it possible to use the assembly according to the invention as a vehicle.
(FR)
L'invention porte sur une échelle combinée à trois fonctions de transport différentes pouvant être transformée en escabeau, en échelle longue, en diable, ou en véhicule, et utilisable par des artisans ou magasiniers requérant un ensemble simple à usages multiples. Les deux côtés de l'échelle, maintenus ensemble par deux articulations (1 et 2) située sur la marche la plus haute (3), pivotent autour de l'axe S1 et peuvent se verrouiller au moyen d'un cran rappelé par ressort (12) fixé à un piston de verrouillage. Un plateau (8) pivotant autour de la marche arrière la plus basse présente une forme permettant de maintenir les deux volées ensemble en se refermant sur la marche avant la plus basse. Un mécanisme de verrouillage à culbuteur (9) pousse sous l'effet d'un ressort la tête dudit culbuteur dans l'une de deux ouvertures pour placer le plateau soit parallèlement, soit perpendiculairement à l'échelle. Les roues peuvent également se verrouiller le long des côtés de l'échelle ou à 90°, à l'opposé du plateau, au moyen d'un mécanisme de verrouillage placé sur un manchon de la suspension des roues, analogue à celui (9) de verrouillage du plateau par culbuteur (9a). Une roue supplémentaire montée sur la marche la plus haute permet selon l'invention d'utiliser l'ensemble comme véhicule.
