Pushcart

A push cart comprising a pair of longitudinally extending upper rods, a pair of lower rods disposed below said upper rods and extending substantially parallel to said upper rods, a pair of front legs turnably connected to the respective front ends of said upper rods and the respective front ends of said lower rods and extending further downwardly from said lower rods, said front legs each having a front wheel, a pair of push rods turnably connected to the respective rear ends of said upper rods and the respective rear ends of said lower rods and extending upwardly from said upper rods, a grip rod connecting said pair of upper rods, a pair of rear leg connecting members turnably connected at one of their respective ends to said push rods, a pair of rear legs turnably connected to the other ends of said rear leg connecting members and adapted to abut at their upper end surfaces against the back surfaces of said push rods when the other ends of the rear leg connecting members are positioned relatively low with respect to their connecting portions associated with the push rods, said rear legs each having a rear wheel, a pair of rear leg connecting rods turnably connected at their front ends to portions in the vicinity of the connecting portions between said lower rods and said push rods and turnably connected at their rear ends to said rear legs, front and rear support blocks connecting said pair of front legs and said pair of rear legs in a plane defined between said pair of lower rods and said pair of rear leg connecting rods, and stop means for defining the terminal ends of the lower rods positioned forwardly of the upper rods so that the lower ends of the front legs are positioned forwardly of their upper ends and so that the lower ends of the push rods are positioned forwardly of their upper ends to form a link mechanism as a parallelogram defined by said upper rods, said front legs, said lower rods and said push rods.
