Abstract
A stroller has a first frame part and a second frame part capable of movement between at least two positions relative to the first frame part. A push-pull mechanism has a push-pull element that directly or indirectly connects the first and second frame parts. Moving the first frame part causes the push-pull mechanism to move the second frame part. The mechanism can be employed on the stroller frame to assist in folding and/or unfolding the stroller.
Claims20
A foldable stroller movable between a folded configuration and an in-use configuration and having a pair of frame sides, each frame side comprising:
- a push bar with a lower end and an upper end;
- a front leg having an upper portion;
- a guide section connecting the front leg and the push bar, the lower end of the push bar coupled to one end of the guide section and the upper portion of the front leg coupled to another end of the guide section;
- and
- a push-pull fold assist mechanism coupled to the push bar, the guide section, and the front leg,
- wherein the push bar moves to a position retracted relative to the one end of the guide section and the front leg moves to a position retracted relative to other end the guide section in the folded configuration,
- wherein the push bar moves to a position extended relative to the one end of the guide section and the front leg moves to a position extended relative to the other end of the guide section in the in-use configuration, and
- wherein the push-pull fold assist mechanism is configured so that pushing the push bar toward the one end of the guide section retracts the push bar relative to the guide section and automatically retracts the front leg relative to the other end of the guide section.
A stroller comprising:
- a first frame part;
- a second frame part capable of movement between at least two positions relative to the first frame part;
- and
- a push-pull mechanism having a push-pull element directly or indirectly connecting the first and second frame parts, the push-pull element including at least one metal tape strip and a roller carried on part of the stroller, the at least one metal tape strip routed around the roller and having an end connected to each of the first and second frame parts,
- wherein moving the first frame part causes the push-pull mechanism to move the second frame part.
A stroller comprising:
- a first frame part;
- a second frame part that is capable of movement between at least two positions relative to the first frame part;
- a third frame part that is capable of movement between at least two positions relative to the first and second frame parts;
- and
- a push-pull mechanism having a push-pull element directly or indirectly connecting the first, second, and third frame parts,
- wherein moving the first frame part causes the push-pull mechanism to move the second and third frame parts.
A stroller having a frame assembly movable between a folded configuration and an in-use configuration and having a pair of frame sides, each frame side comprising:
- a first frame part;
- a second frame part capable of movement between at least two positions relative to the first frame part;
- and
- a push-pull mechanism having a push-pull element directly or indirectly connecting the first and second frame parts,
- wherein moving the first frame part causes the push-pull mechanism to move the second frame part,
- wherein the first frame part is a push bar of a handle assembly and the second frame part is a front leg, and
- wherein the push bar and the front leg can slide parallel to one another between an extended length in the in-use configuration and a retracted length in the folded configuration, the retracted length being shorter that the extended length.
A stroller having a frame assembly movable between a folded configuration and an in-use configuration and having a pair of frame sides, each frame side comprising:
- a first frame part;
- a second frame part capable of movement between at least two positions relative to the first frame part;
- a push-pull mechanism having a push-pull element directly or indirectly connecting the first and second frame parts;
- and
- a guide section, wherein the first frame part is a push bar with a lower end coupled to one end of the guide section and the second frame part is a front leg having an upper portion coupled to another end of the guide section,
- wherein moving the first frame part causes the push-pull mechanism to move the second frame part.
