Abstract

An infant stroller having a fold latch mechanism to lock the stroller in the unfolded or deployed configuration. The side of the stroller contains a latchkey piece having a pocket-like recess that engages a latchpin on the stroller's front leg. When the latchkey is in the locked position, the front legs are held in place, locking the stroller in the unfolded or deployed configuration. When the latchkey is disengaged from the latchpin on the front leg, the front leg can be rotated to allow the stroller to be folded for storage or transport. The stroller also has a latching mechanism for locking the tray unit in place during normal use. The tray unit becomes unlocked and can be tucked away during the folding process.

Claims22

Dependent claims

An infant stroller comprising:

at least one side member;
at least one front leg joined to the side member and capable of rotating with respect to the side member, the front leg having a nub capable of engaging a latchkey for preventing rotation of the front leg with respect to the side member;
at least one rear leg joined to the side member and capable of rotating with respect to the side member;
at least one handle bar joined to the side member;
a locking mechanism for preventing rotation of the front leg with respect to the side member, the locking mechanism comprising a latchkey pivotally attached to the side member, the latchkey having a recess capable of engaging the nub on the front leg, and the latchkey capable of rotating with respect to the side member;
and
at least one frame member pivotally joining the front leg to the rear leg and capable of preventing the rear leg from pivoting away from the front leg when the front leg is locked by the locking mechanism;
wherein
the front leg is locked in a fixed position with respect to the side member when the latchkey is positioned such that its recess is engaged with the nub on the front leg;
and wherein
the front leg is unlocked, thereby capable of rotating with respect to the side member, when the latchkey is positioned such that its recess is disengaged from the nub on the front leg.

8 more elements

An infant stroller comprising:

at least one side member;
at least one front leg joined to the side member and capable of rotating with respect to the side member;
a tray unit including a tray and at least one tray arm, the tray arm joined to the side member and capable of rotating with respect to the side member, the tray arm having a graduated recess on its side face having a deep end and a shallow end, the shallow end being flush with the side face of the tray arm;
and
a tray locking mechanism for preventing rotation of the tray arm with respect to the side member, the tray locking mechanism comprising:
a frame;
a latchpin capable of engaging the recess in the tray arm;
a carrier for holding the latchpin in place and capable of sliding within the frame;
a first spring to provide restoring force to the latchpin when depressed;
and a second spring to provide restoring force to the carrier;
wherein
the latchpin is engaged with the deep end of the recess on the tray arm when the front leg is in an unfolded position with respect to the side member, thereby locking the tray arm and the tray in a fixed position with respect to the side member;
and wherein
the latchpin is engaged with the shallow end of the recess on the tray arm when the front leg is in a folded position with respect to the side member, thereby allowing the tray arm and the tray to rotate with respect to the side member.
