Abstract
Foldable strollers are disclosed herein. An example stroller disclosed herein includes a housing. The example stroller also includes a first pivot and a second pivot coupled to the housing, and a follower is coupled to the first pivot and the second pivot to move with the first pivot and the second pivot. The example stroller also includes a lock to selectively lock the follower in a locked state to secure the first pivot and the second pivot in a first position.
Claims40
A stroller, comprising:
- a wheeled frame comprising a first side and a second side, the first side of the frame including:
- a first frame member, a second frame member and a third frame member;
- a housing coupled to the first frame member;
- a first pivot coupled to the second frame member and rotatably coupled to the housing;
- a second pivot coupled to the third frame member and rotatably coupled to the housing;
- a follower slidably coupled to the first frame member;
- a first link rotatably coupled to the first pivot and the follower;
- and
- a second link rotatably coupled to the second pivot and the follower to operatively couple the third frame member to the second frame member.
A stroller, comprising:
- a housing;
- a first pivot coupled to the housing;
- a second pivot coupled to the housing;
- a follower coupled to the first pivot and the second pivot to move with the first pivot and the second pivot;
- and
- a lock to selectively lock the follower in a locked state to secure the first pivot and the second pivot in a first position.
A stroller, comprising:
- a follower slidably coupled to a first frame member;
- a first link rotatably coupled to the follower and a second frame member;
- a second link rotatably coupled to the follower and a third frame member;
- and
- a lock to engage the follower in a locked state to secure the second frame member and the third frame member in a first position, and to disengage the follower in an unlocked state to enable the follower to move relative to the first frame member to enable the second frame member and the third frame member to rotate from the first position to a second position.
A method of folding a stroller comprising a first frame member and a second frame member in a first position, the method comprising:
- disengaging a lock from a follower rotatably coupled to the first frame member and the second frame member;
- and
- moving the follower with the first frame member and the second frame member to fold the stroller to a second position.
A method of manufacturing a stroller, comprising:
- coupling a housing to a first frame member;
- movably coupling a follower to the first frame member;
- rotatably coupling a second frame member to the follower and the housing;
- rotatably coupling a third frame member to the follower and the housing;
- and
- coupling a lock to the stroller to enable the lock to engage the follower in a locked state.
