ABSTRACT:
An invalid carriage including a chair of pivotted construction with a connection between the back of the chair and a mast that is fixed to a chassis. There are means to raise the connection up the mast, so raising the chair seat from horizontal to forwardly-sloping so as to help raise a user of the chair from a sitting to a standing position, and to lower the connection so that the reverse occurs so as to help a standing person to sit down in the chair. As the mast connection moves, so collapsing or expanding the chair framework, wheels allow the feet of the front legs of the chair to move backwards and forwards over the chassis. In an alternative construction the feet of the front legs are anchored to the chassis, and the foot of the mast rolls backwards and forwards over the chassis as the mast connection moves.
