Abstract:
A stroller arrangement, comprising:an ""X"" frame base having a pair of cross elements with front ends and rear ends;a main seating support frame pivotally coupled to said front ends and comprising a back support;a primary support structure pivotally coupled to said rear ends and extending forwardly to be pivotally coupled to said main seating support frame and comprising a seat support, and said primary support structure further comprises:an elongated telescoping arrangement having an outer tubular member and an inner member slidable within said outer tubular member, one of said inner and outer telescoping members being pivotally coupled to said main seating support frame, and the other of said telescoping members being pivotally coupled to said rear ends of said cross elements, andan indexing mechanism for selectively incrementally changing the length of the telescoping arrangement between the pivotal connection at the main seating support frame and the pivotal connection at the rear ends of the cross elements,a releasable rigid latch maintaining said cross elements angularly displaced from one another; wherebyupon release of said rigid latch, said cross elements may be brought together laterally to collapse said ""X"" frame base and fold said main seating support frame and said primary support structure against one another and against said collapsed ""X"" frame base;coupling devices for maintaining said back and seat supports at a relative angle with respect to each other of approximately 90.degree. when said stroller arrangement is in use and said rigid latch is maintaining said cross elements angularly displaced from one another; and,each of said coupling devices comprises an indexing mechanism for selectively incrementally changing the length of said primary support structure, thereby varying the angle between said seat support and said back support, defining a range of seating positions from relatively upright to relatively recumbent.
