Patent

CA 2189956

The invalid hoist comprises a mobile chassis, a lifting column upstanding from the chassis and a lifting arm supported by the lifting column. The chassis comprises a main portion extending transversely of the hoist and side members which are movably between a first in use position in which they project forwardly from the main portion and a second storage position (as shown) in which they extend parallel or substantially parallel to the lifting column. Releasable means may be provided for holding the lifting arm in an operative position and for releasing the lifting arm in an operative position and for releasing the lifting arm to allow it to pivot into a storage position alongside the lifting column. Alternatively an extensible, retractable device (see figure 5) may be connected between the lifting arm and the lifting column at positions remote from the pivot axis between the lifting arm and the lifting column so that the lifting arm can be moved between an operative position and a storage position alongside the lifting column.

Un dispositif de levage pour invalides comprend un châssis, mobile (10), une colonne de levage (11) montée verticalement sur ce châssis et un bras de levage (12) supporté sur cette colonne. Le châssis comprend une portion principale (13), transversale par rapport au dispositif de levage, et deux éléments latéraux (14) pouvant se déplacer entre une première position opérationnelle, où ils se projettent vers l'avant depuis cette portion principale, et une deuxième position de rangement (comme illustré) où ils sont parallèles ou presque à la colonne de levage. On peut équiper ce dispositif de systèmes libérables (22) qui maintiennent le bras de levage en position opérationnelle et peuvent le libérer et lui permettre de pivoter en position de rangement le long de la colonne de levage. Il est également possible de raccorder un dispositif déployable et rétractile (fig. 5) entre le bras de levage et la colonne de levage en des positions éloignées de l'axe de pivotement reliant ces deux éléments, de façon qu'on puisse déplacer le bras de levage entre la position opérationnelle et la position de rangement le long de la colonne de levage.
