Patent ID: 8474854

Claim:
A foldable stroller comprising: a frame assembly having a frame fold joint and being reconfigurable between a set-up configuration and a folded configuration; a fold latch on the frame fold joint movable from a latched position with the frame assembly in the in-use configuration to a released position, the fold latch having a notch; a mounting point on the frame assembly defined by a connector that has a lock pin parallel to and offset from a frame pivot axis, the lock pin being spring biased to project from the connector; a child support structure having a mount attachable to the frame assembly at the mounting point and being detachable from the mounting point and removable from the frame assembly, the mount including a mount surface; and an interlock mechanism coupled to the mounting point and movable between a locked state locking the frame assembly in the set-up configuration and an unlocked state permitting the fold latch to move to the released position thereby permitting the frame assembly to be reconfigured to the folded configuration, wherein, with the frame assembly in the set-up configuration and the child support structure attached to the mounting point, the mount is coupled with the connector and the mount surface bears against the lock pin pushing the lock pin into the notch preventing actuation of the fold latch and thereby the interlock mechanism is retained in the locked state, and wherein, to fold the frame assembly, the child support structure is first detached from the mounting point and the mount surface releases the lock pin from the notch, which moves the interlock mechanism to the unlocked and permits actuation of the fold latch thereby allowing the stroller to be moved to the folded configuration.
