Abstract: A safety helmet includes a shield movable relative to a shell from an open to a closed position, and vice-versa through operation of a shield actuation system. When in the closed position, the shield actuation system permits the shield to be aligned substantially flush with the shell. Further, the shield actuation system allows the shield to be opened through a manual process that includes pushing on a lever or button to initially release the shield and then rotate the shield into the open position. The shield actuation system includes a number of plates with at least two of the plates in kinematic cooperation for allowing the shield to pop out and then rotate relative to the shell.

Abstract: A mobile portable playyard system is disclosed. The system generally includes a playyard structure for a child and a carrying case. In the folded position, the playyard structure is disposed within the carrying case. The playyard structure includes two wheels and the carrying case includes a towing strap for convenient transport of the system. The preferred bottom portion of the carrying case includes a member which provides stability to the wheels and to a pair of feet which extend therethrough. The member stabilizes the wheels and feet and insures that a minimum relative distance between the wheels and feet exists to provide for a stable support structure to maintain the system in an upright position. A carrying handle and a zippered closure are also provided.
