Abstract
Abstract A baby carriage comprises an upper frame portion having two spaced apart tubular legs which converge upwardly and terminate in a handle. The handles include hook-shaped end portions forming cane-like ends which may be rotated into juxtaposition to facilitating the carrying of the baby carriage on the arm of a person. A lower frame portion having spaced apart legs is carried on a bracket which pivoted to the upper frame portion and a lower rear frame portion is carried on a bracket which is pivoted to the lower frame portion. Both the lower frame portion and the lower rear frame portion carry wheels for moving the baby carriage and they are held in an extended position by a hookshaped member which is carried on the upper frame portion and which hooks over the projection of a bracket supporting the lower rear frame portion from the lower frame portion. A seat-forming fabric provided with an upper part which engages over the converging portions of the upper frame and is buttoned in position thereon. It includes a lower hard seat portion which extends horizontally and which is supported by side elements which are folded over and buttoned upon an outwardly extending rigid frame forming member which is pivoted on the lower frame portion and on a link which extends to the upper frame portion. Both the seat and the lower frame portion and the lower rear frame portion are foldable upwardly into juxtaposition with the upper frame portion to facilitate carrying of the carriage. The carriage also includes a fabric forming a closed top or parasol which includes an inner end which buttons over the upper frame and an outer end which overhangs the seat portion and provides a shade or covering. A lower foot receiving bag-like fabric member forms a foot portion for the occupant of the carriage which includes an opening which aligns with the front end of the seat portion and which includes side portions which engage upwardly and button to the covering or parasol portion. The construction is such that the parasol portion may fold upwardly against the upper frame portion along with the seat and the foot covering portion when the lower frame portion and the lower rear frame portions are folded into juxtaposition with the upper frame portion for carrying of the device on a person''s arm.
