ABSTRACT:
The stroller includes a frame inclined downward and forward, the frame having left and right side frame members joined by a handle at their upper rear ends. A single front wheel is mounted on an axle at the lower front end of the frame. Left and right swing arms extend downward and rearward from pivotal attachments on the left and right side frame members, respectively. Left and right rear wheels are mounted on axles at the lower ends of the swing arms. There is no rigid connection or horizontal member between the front and rear axles, thereby permitting the stroller to clear higher curbs or carry cargo that extends into the space between the front and rear axles, while also reducing the weight of the stroller. On each side of the stroller a resilient member is detachably connected between the swing arm and a point on the side frame member above and to the rear of the point at which the swing arm is attached. The resilient members yieldingly oppose pivotal motion of the swing arm in both rotational senses from an equilibrium position. Disconnection of the resilient members permits the swing arms to be pivoted forward for storage or transportation with the rear wheels much closer to the front wheel.
