Collapsible frames for baby carriers

A frame mechanism for opening or closing frames for strollers, carriages and the like, comprising, in combination, at least a pair of spaced apart legs, each leg carrying at its lower end one or more wheels, a transversely disposed rod member connected to each of said legs with said legs extending above and below said transverse rod member, a longitudinally disposed elongated support member disposed between said legs, said longitudinal support member including openings through which said transverse rod member extends, said openings defining a path of movement for said transverse rod member as said transverse rod member is pulled upwardly thereby carrying said legs and wheels to a collapsed position, leg contact means disposed on said longitudinal support member and extending above and below said rod member, whereby said legs may be collapsed by pulling up on said transverse rod member causing said leg contact means to contact upper portions of said legs thereby causing the lower portions of said legs and said wheels attached thereto to pivot inwardly on said transverse rod member and when it is desired to open the legs and wheels, the transverse rod member is moved downwardly thereby causing said leg contact means to contact lower portions of said legs and thereby force said lower portions of said legs and said wheels to move outwardly to and remain in their open position.
