Problems solved by technology

These rubber covers add unnecessary expense and complexity to the stroller design without realizing suspension or other functional benefits
In addition, due to the relatively limited range of travel of traditional rocker-type suspension systems, it is difficult for the user to perceive the wheel suspension in the stroller

Embodiment Construction

[0024] Referring now to the drawings, FIG. 1 is a perspective view of an example of a stroller wheel 20 having a modular or integrated suspension feature constructed in accordance with the present invention. The stroller wheel 20 is attached to an integral frame portion 22 of the stroller 24 . The stroller wheel 20 may be mounted for rotation about the wheel axis or roll axis W on the frame portion 22 in any suitable manner. In the example shown in Figure 2, the frame portion 22 carries a solid axle 26 upon which the wheel 20 may be mounted for rotation in a conventional manner. The wheel 20 may be retained on the solid axle in any suitable manner, such as using a cross hole and cotter pin 28 on the end of the axle 26 shown in FIG. 1 , or using a C-ring and slot arrangement, or the like. In another example, a portion of the wheel 20 may carry an axle (not shown) rotatably connected to the frame portion 22 . The wheels may be mounted in a variety of ways within the spirit and...

Abstract

A stroller wheel has a wheel rim, a wheel hub, and a suspension system integrated between the wheel rim and the wheel hub. The integrated or modular suspension system permits resilient movement of the wheel hub and the wheel rim relative to one another during normal stroller usage. A stroller can include a stroller frame and one or more of the suspended wheels coupled to the stroller frame for rotation about an axis.

Description

technical field [0001] The present invention relates generally to strollers, and more particularly to stroller wheel structures with integral or modular suspension systems. Background technique [0002] Strollers known in the art use various wheel suspension mechanisms. These strollers typically use suspension systems that are integral to the frame or are part of the wheel-frame swivel joints. With these suspension systems, it is difficult to add or subtract suspension elements to a particular stroller or family of strollers without major design modifications to the stroller frame and / or swivel joint structure. [0003] Most stroller suspension systems are of the rocker type. These systems use coil springs and often a bellows arrangement connected to a rocker arm on a frame section or swivel joint. The suspension system allows the swing arm to which the wheel is attached to pivot up and down. Wheel suspension is accomplished by this movement of bias against a spring or o...
