Abstract: A child enclosure including a hub member including a crank link, a substantially four bar linkage articulated link operably connected to the crank link, a push rod connected to the substantially four bar linkage articulated link so that linear movement of the crank link effects, through the substantially four bar linkage articulated link, a linear driving motion of the push rod, a side structure having a plurality of side posts a rack assembly movably coupled to the side post, the rack assembly includes a gear rack that is coupled with an upper end of the push rod so as to reciprocate with the linear driving motion of the push rod and extend and retract the rack assembly, an upper assembly having upper arms, each upper arm being pivotally coupled to a respective side post.

Abstract: A foldable enclosure apparatus, for a child, including an upper assembly forming an upper portion of an enclosure, and a base assembly connected to the upper assembly and forming a lower portion of the enclosure that supports a base pad. The upper assembly and base assembly are coupled by a side structure of posts, and the upper assembly, base assembly, and side structure are configured so that the foldable enclosure apparatus folds and unfolds effecting closing and opening of the foldable enclosure apparatus between closed and open positions. A flexible frame bassinet is included in the upper portion and dependent from the upper assembly. A changing platform, separate and distinct from the bassinet, is connected to the upper assembly. The changing platform is pivotally mounted to the upper assembly with mounts separate and distinct from mounting of the bassinet, the mounts include a hinged coupling and snap on clamps.

Abstract: A folding chair includes a backrest and a pair of armrests pivotally coupled to the backrest. A pair of rear legs are pivotally coupled to the backrest and define a rear leg angle therebetween. A pair of front legs are pivotally coupled to respective armrests and define a front leg angle therebetween. A pair of wheels are coupled to the backrest. The folding chair is positionable in a deployed configuration wherein distal ends of the rear and front legs are in coplanar alignment. The folding chair is also positionable in a folded configuration wherein distal ends of the rear legs and the front legs are in non-coplanar alignment with each other and the wheels are positioned to roll the folding chair on a support surface. The rear and front leg angles decreasing as the folding chair transitions from the deployed configuration toward the folded configuration.

Abstract: A child enclosure including a hub member including a crank link, a substantially four bar articulated link operably connected to the crank link, a push rod connected to the substantially four bar articulated link so that linear movement of the crank link effects, through the substantially four bar articulated link, a linear driving motion of the push rod, and a slide wedge coupled to the push rod, the slide wedge includes a slider and a pivot surface biasing the slider transverse to the linear driving motion of the push rod, where the linear driving motion of the push rod extends and retracts the slider.
