(01. 280—41) 1 2 This invention relates to a combination baby ' The herein described invention was designed “stroller” and high chair whichmay be quickly folded with ‘one hand into'a compact package fora general utility go-cart- or stroller so“con~ structed that it may be set up or folded with one hand by a person holding a child, and therefore which may be carried like a hand bag. Another object of the invention is to provide a not having the use of the other hand, and which when folded, automatically locks itself into a combination “stroller” and chair which folds into ‘ a substantially square package. Another object of the invention is to provide a combination stroller and chair which may be folded outward and downward instead of in com mon scissor manner. compact, relatively small package, which requires little room in crowded and close quarters such as w Another object of the invention is to provide a combined go-cart and chair which may be stores, busses, cars etc. and for storage purposes. Also when folded it may readily be carried as a hand bag and which also provides a stool upon which an adult may sit. ‘ " ‘ In the accompanying drawings I indicates my quickly folded with one hand, and which auto improved stroller or go-cart which comprises a matically locks itself in such folded position, the 15 seat 2, a back 3, a handle 4, legs 5, 6, 1 and 8, a lock being manually thrown open. foot rest 9, and wheels H], H, l2, and I3, and side A further object of the invention is to provide a go-cart which may be folded to form a stool for an adult. arms I4 and I5.
