ABSTRACT:
The invention relates to a folding wheeled chair/luggage carrier of the kind having a pair of side frames which can be folded between an erected, spaced side-by-side position and a stowage position via releasable locking means, and thereafter collapsed fan-wise into a stowage bundle, each side frame comprising pivotally connected back and base support and bracing bars and one or more struts which are pivotally connected between the free ends of said back and base support and bracing bars.
A pair of seat bars are pivotally connected at corresponding intermediate positions to respective back support bars of said side frames for pivoting between a stowage position substantially in alignment with said back support bars to a use position in which their free ends extend forwardly, a fabric seat panel being fixed between the seat bars. The free ends on the seat bars are supported in their use position by releasable catches mounted on locking sleeves constituting said locking means, which sleeves are attached to the bracing bars and are maintained, via stop means, in locking positions closely embracing the pivot connections of respective struts by the weight of the occupant, thereby ensuring the struts cannot collapse in use of the chair.
