  • Patent number: 7717457
    Abstract: A spring-assisted fold mechanism for a child's stroller is operable to collapse the stroller frame into a storage configuration upon actuation of a release mechanism controlling the stroller fold latch mechanism. The stroller includes a spring device interconnecting two of the pivotally connected frame components to urge the pivotal movement thereof into a collapsed, folded configuration. An anti-fold latch mechanism is associated with the stroller seat to move from an inoperative position into a locking position whenever a child is placed into the stroller seat to prevent the fold mechanism from collapsing the frame of the stroller until the child is removed from the seat. The spring device can be configured as a gas spring, a torsion spring, a compression spring or an elastomeric member that can be stretched to exert a biasing force on the stroller frame to urge movement into the collapsed position.
