The folding mechanism, a unique feature of the design is directed toward compactness, ease of use, reliability, and reduction in manufacturing costs.
Claims25
A stroller, comprising:
- a pivot member;
- a first rotatable member with a first aperture having a first gear, wherein the first gear is formed at a first edge portion of the first rotatable member defining a portion the first aperture;
- a second rotatable member with a second aperture having a second gear, wherein the second gear is formed at a second edge portion of the second rotatable member defining a portion of the second aperture;
- and
- a third gear positioned in driving engagement with the first gear and the second gear so that the first rotatable member and the second rotatable member rotate relative to each other in geared coordination;
- wherein the first edge being radially outward of the axis of the third gear and the second edge being radially inward of the axis of the third gear, the first and second rotatable members being rotatably coupled to the pivot member to rotate about common axis of rotation.

A stroller, comprising:
- left and right side laterally spaced-apart first members, each of the first members having a first end portion, a second end portion, and connected through their first ends;
- left and right side laterally spaced-apart second members, each of the second members having a first end portion, a second end portion, and connected through their first ends;
- left and right side laterally spaced-apart third members, each of the third members having a first end portion, a second end portion, and connected through their first ends;
- and
- left and right side laterally spaced-apart folding assemblies, each of the left and right side folding assemblies having a first rotatable plate and a second rotatable plate rotatably mounted on a pivot member to pivot about a common axis in parallel planes, the first rotatable plate having a first aperture with a first gear and the second rotatable plate having a second aperture with a second gear, each of the left and right side folding assemblies further having a third gear positioned in both the first and second apertures such that the first gear is formed at a first edge portion of the first rotatable plate defining a portion of the first aperture and the second gear is formed at a second edge portion of the second rotatable plate defining a portion of the second aperture of each the left and right side folding assemblies, with the first edge being radially outward of the axis of the third gear and the second edge being radially inward of the axis of the third gear, such that the third gear is in driving engagement with the first gear and the second gear so that the first rotatable plate and the second rotatable plate rotate relative to each other in geared coordination.

A stroller, comprising:
- a folding assembly comprising
- a first rotatable member and a second rotatable member rotatably mounted to rotate relative to each other, the first rotatable member being positioned for rotation in a first rotation plane and the second rotatable member being positioned for rotation in a second rotation plane spaced apart from the first rotation plane, the first rotatable member having a first gear portion and the second rotatable member having a second gear portion;
- and
- a third gear extending between the spaced apart first and second rotation planes and positioned such that the first rotatable member has a first aperture and the first gear is formed at a first edge portion of the first rotatable plate defining a portion of the first aperture and the second rotatable member has a second aperture and the second gear is formed at a second edge portion of the second rotatable member defining a portion of the second aperture, with the first edge being radially outward of the axis of the third gear and the second edge being radially inward of the axis of the third gear such that the third gear is in driving engagement with both the first and second gear portions so that the first rotatable member and the second rotatable member rotate relative to each other in geared coordination.
