Abstract

Baggage trolley or invalid chair has mechanism enabling the fore or rear pair of wheels to be lowered simultaneously to maintain the platform horizontal when the vehicle traverses a gradient or moving stair case. Pref. a compound leverage system assisted by the distributed weight of the charge effects the adjustment, with wheel supports locking at the height the user desires, and levers being connected back to the chassis whereby the user can adjust the level and apply the brakes at will. Wheels (3) are mounted on horizontal stub axles projecting form vertical shafts (2), these latter being tied upperly and horizontally (10) and sliding in longitudinally slotted tubes (1) telescope fashion: locking being achieved via a spring pawl catching shaft indentations. An end articulating, folding transverse X frame is pinned to tubes, shaft tie (10) and vertical chassis hangers (7).
