Apparatus for lifting or/and lowering objects or, primarily, persons which comprises two interconnected X-frames (4,5) each of which comprises two pivotally connected members and which are arranged in an upright position in spaced parallel relationship, a support (3) supported by the upper ends of the members, and one of two inflatable bags (2,332) arranged to surround the pivotal connections (6) of the frame members so that portions of the bag(s) lie between members, whereby inflation and deflation of the bag(s), respectively, opens the X-frames in scissors-fashion and allows the frames to close in a similar fashion thereby raising and lowering the support. The bag has a central opening through which the frame members extend and a tie (11,12) is provided between portions of the bag at opposite sides of the opening.
L'invention concerne un appareil de levage et/ou d'abaissement d'objets ou principalement de personnes. Cet appareil comprend deux cadres en X (4,5) reliés comportant respectivement deux éléments reliés pivotants et disposés parallèlement dans une position verticale, un support (3) porté par les extrémités supérieures des éléments, et un ou deux sacs gonflables (2,32) conçus pour entourer les connexions pivots (6) des éléments cadres de telle manière que des parties du/des sac(s) se situent entre des éléments. Le gonflement du/des sac(s) ouvre les cadres en X à la manière d'une paire de ciseaux et leur dégonflement permet aux cadres de se fermer de manière similaire, ce qui permet respectivement de soulever et d'abaisser le support. Le sac a une ouverture centrale par laquelle passent les éléments cadres et une attache (11,12) est placée entre les parties du sac sur les côtés opposés de l'ouverture.
