摘要:
A detachable ladder is disclosed that includes a lower frame (10) including two substantially trapezoidal legs (11), a first board (13) interconnecting tops of the legs (11), and one or more crosspieces (14) interconnecting the legs (11); and an upper frame (20) including two side units (21) each including a substantially trapezoidal upper element having its forward end pivotably secured to a top front end of the leg (11) and a lower support extended downward from the upper element, a second board (23) interconnecting bottoms of the upper elements, a third board (24) interconnecting tops of the upper elements, and one or more fourth boards interconnecting intermediate portions of the upper elements. Pivoting the upper frame (20) about the lower frame (10) until the tops of the upper elements rest upon a supporting ground will convert the ladder into a chair.

Le marchepied selon l'invention comprend un premier élément (2) à surface supérieure formant une première plateforme (4) et à base d'appui (3) munie de roulettes escamotables (14). Un second élément (5) peut être posé sur le premier élément (2) et comporte une surface supérieure généralement plane formant une seconde plateforme (6), avec des pieds (7, 8, 9) qui peuvent être positionnés sélectivement sur l'une ou l'autre de deux séries de zones d'appui différentes du premier élément (2). Lorsque le second élément (5) est posé sur une première série de zones d'appui (11a, 11 c), la seconde plateforme (6) se trouve à une grande hauteur (H4) de la base (3). Lorsque le second élément (5) est posé sur une seconde série de zones d'appui (10a), la seconde plateforme (6) se trouve à une plus faible hauteur de la base (3). On réalise ainsi une modification simple et rapide de la hauteur du marchepied.
摘要:
Step-stool assemblies and related methods are described. A step-stool assembly (100) comprises an inner base frame (102) and a continuous outer shell (104). The inner base frame (102) includes a first loadable surface (106) near a top thereof. The outer shell (104) unitarily extends from an upper portion (108) to a lower portion (110). The lower portion (110) includes a size and shape disposable around, and attachable with, an outer perimeter of the inner base frame (102). The upper portion (108) is configured to extend above the first loadable surface (106) of the base frame (102) and includes a second loadable surface (112). The outer shell (104) includes at least one foot-receiving aperture (202) to provide access to the first loadable surface (106) when the outer shell (104) and inner base frame (102) are attached. In an example, a perimeter of the shell lower portion is greater than the base frame outer perimeter, while a perimeter of the shell upper portion is less than the base frame outer perimeter.

摘要:
A chair that can be used as a children's chair, comprising a bottom part (1) which carries a seat (2) and a back rest (3). The seat (2) is comprised of a first fixed part (4) and a second part (5) which is hinged to the fixed part such as to enable the second part to be raised from a normal state of use of the chair in which its seating surface (6) is located forwardly of and in the plane of the seating surface (7) of the first part (4), to a position in which the seating surface (6) of the first part rests on the seating surface (7) of the first part (4). The underside of the second part (4) includes a further seating surface (9) which when the second part is raised is located above and spaced from the seating surface (6) of the second chair-part (5).
