Definitions

  • the object of the invention is to provide a hand-propelled carriage of light construction, all the parts of which can be rapidly folded into a small space to enable it to be readily transported.
  • Figure l is an external elevational view of a perambulator constructed in accordance with the invention, in the open position ready for use;
  • Figure 2 is an external plan View corresponding to Figure l;
  • Figure 3 shows the perambulator in the folded position
  • Figure 4 is an external half-view in profile, as seen from the steering end;
  • Figure 5 is a diagrammatic View of the perambulator on a smaller scale, the dot-and-dash lines representing the position of the folded panels, and
  • Figure 6 is a plan view corresponding to Figure 5, the dot-and-dash lines again representing the position of the folded panels.
  • the device illustrated comprises essentially two independent vertical panels A and B supporting Ythe wheels, which may or may not be resiliently suspended and are situated in the same planes as the panels, .the said two panels being connected together by two pins C and D secured to the base of the centrally disposed handle E used for propelling the carriage.
  • the equal widths n and o of the coupling members G and H are each equal to one half of the Width m of the coupling member F of the handle E.
  • the folding device functions in the following manner:
  • the panel illustrated in solid lines corresponds to its operative position with reference to the handle while the dot and dash illustration of the panel corresponds to its folded inoperative position alongside of the handle after pivoting round the axis -y lying in a plane at middistance between the parallel vertical planes passing through the handle and the panel considered.
  • a seat K independent of the vehicle and constituted by straps or light folding panels is secured to the panels A and B and to the coupling member F.
  • the arrangements is completed by a tie rod L drawing the two panels A and B towards one another in the opening position and securing the whole arrangement in this position.
  • a foldable carriage comprising two independent laterally spaced vertical panels, individual wheels supporting each panel substantially in the vertical plane thereof, a single centrally disposed control handle located obliquely with reference to horizontality in a vertical plane at equal distances from the two vertical panels :and a pivotal connection between each panel and Vthe handle on which said panel is adapted to swing between two positions parallel to the handle round an axis lying in a vertical plane at equaldistanc'es from the vertical plane of the corresponding panel and from the vertical plane passing through the handle, said axis lying in vertical projection along a line equiangularly disposed relatively ⁇ to a horizontal line and to the direction of the handle.
