Claim 1
Independent Claim
188 words
A device convertible to form a baby stroller or baby backpack comprising: a rigid frame structure formed by two elongated, substantially parallel and spaced apart struts which are joined together by at least a first transverse cross member; seat means secured to said frame for receiving and supporting a small child; at least two handles, each of which is extensibly coupled to one of said struts to allow said handle to be protracted out from and retracted to said strut, with a portion of each of said handles being arcuately shaped for positioning on an individual user's shoulders; means for retaining said frame strut and said extensibly coupled handle at a desired position with respect to each other; at least a first frame leg pivotally supported by said frame struts for movement from a substantially collapsed position on said frame to at least a first extended position away from said frame, wherein said leg and said frame define in combination a base upon which said device is supported; and wheel means secured to said frame and said frame leg for allowing said device to be wheeled about thereon.
Claim 2
Independent Claim
