Abstract
A foldable frame for a stroller having front and rear legs with wheels disposed at the ends thereof and a handle support joined at a folding mechanism. The folding mechanism synchronizes motion of the front leg and handle to collapse them adjacent to the rear leg. The mechanism also actuates a swivel mechanism on a front wheel that swivels the front wheel to a predetermined position optimized to allow the stroller to be supported by the wheels when folded.
Claims19
A foldable stroller frame comprising:
- a frame having a pair of front legs, a pair of rear legs, and a handle;
- right and left folding mechanisms connecting respective front legs, rear legs, and the handle in a manner to synchronize movement thereof between folded and deployed positions;
- and
- a swivel assembly connecting a front wheel to at least one of the pair of front legs, the swivel assembly enabling rotating movement of the front wheel about a generally upstanding swivel axis and having a cam surface sloped between a high point and a low point encircling the swivel axis, the swivel assembly further having a positioner moveable by an actuator in engaging and releasing directions that, when moved in the engaging direction, contacts the cam surface and rotates the front wheel toward a predetermined position, the actuator connecting to at least one of the folding mechanisms to move the positioner to the engaged position when the stroller is moved from the deployed position toward the folded position.

A foldable frame for a stroller comprising:
- a front leg having a front wheel disposed at a distal end thereof;
- a rear leg having a rear wheel disposed at a distal end thereof;
- a handle support having a handle disposed at a distal end thereof;
- a folding mechanism connecting proximal ends of the front leg, the rear leg, and the handle support in a manner enabling folding movement between a folded position and a deployed position;
- a swivel assembly connecting the front wheel to the front leg, the swivel assembly enabling rotating movement of the front wheel about a generally upstanding swivel axis and having a cam surface sloped between a high point and a low point encircling the swivel axis, the swivel assembly further having a positioner moveable by an actuator in engaging and releasing directions that, when moved in the engaging direction, contacts the cam surface and rotates the front wheel toward a predetermined position, the actuator connecting to the folding mechanism to move the positioner to the engaged position when the stroller is moved from the deployed position toward the folded position.

A foldable stroller frame comprising:
- a front leg having a front wheel disposed at a distal end thereof;
- a rear leg having a rear wheel disposed at a distal end thereof;
- a handle support having a handle disposed at a distal end thereof;
- and
- a folding mechanism connecting proximal ends of the front leg, the rear leg, and the handle support, the folding mechanism having a base member connected to the rear leg, a first member support pivotally connected to the base member, the first member support having an extension axis and an offset connector spaced apart from the first member extension axis and moving in an arc as the first member support is pivoted, a second member support pivotally connected to the base member, the second member support having an extension axis and an offset connector spaced apart from the second member extension axis, and a link member connecting the first member offset connector and the second member offset connector, the link member causing simultaneous pivotal movement of the second member support when the first member support is pivoted.
