Abstract
Abstract A push chair which incorporates a shopping trolley has a wheeled front frame with front wheels (22) and rear wheels (23), a seat 11 for a child, and a support member (10) for an article-carrying container (14). The frame can be folded to reduce the separation between the front and rear wheels so that the front/rear dimension of the push chair is reduced. The seat (11) of the chair is folded up at the front and the handle (40) is folded down at the rear. An auxiliary handle (16) on the support member controls the push chair when it is folded.
