Abstract
This invention is concerned with a folding four wheeled frame for a pushchair which has two front and two rear upwardly extending supports each of which carries at its lower end a wheel. The supports are pivotally connected to an upwardly extending backbone, and also connected near their lower ends to the lower end of the backbone by means of separate pivotal links. The front supports are connected near their upper ends to a first mounting adjacent to the top of the backbone by means of separate pivotal links, and the upper ends of the rear supports are pivotally connected to a second mounting on the backbone adjacent to the first mounting. The arrangement of the supports, backbone and mountings is such that the two mountings can be moved relatively to one another along the backbone whereupon the pivotal links enable the four supports to swing between a closed position nearer to the backbone and an open position further away from the backbone.
