A suitcase has a suitcase body defining a compartment sized and shaped to receive one or more articles. The suitcase body has opposite upper and lower ends and opposite front and rear sides. A seat is connected to the suitcase body. The seat is selectively configurable in a stowed configuration and a deployed configuration in which the seat is arranged to carry a person. A front pair of wheels is disposed adjacent to the lower end and adjacent to the front side. A rear pair of wheels is movable between a first position and a second position relative to the suitcase body. The rear pair of wheels in the first position is disposed adjacent to the lower end and adjacent to the rear side. The rear pair of wheels in the second position is spaced rearward of the lower end and the rear side.

A portable activity center for use by a young child comprising a frame supported at a predetermined height above the ground by a plurality of rotatable or foldable legs. A tray is coupled to the frame and includes an opening and a seat support surrounding the opening and a seat is positioned within the opening and is securely attached to the seat support. A resilient suspension system operates to permit the seat and seat support to move in vertical reciprocating movement to allow the child to bounce. A cover interchangeable with the seat and positioned within the opening operates to convert the activity center into a table structure.

A child's folding walker with caster wheels that is adjustable in height to permit a child to sit and touch the ground and move the walker. The walker includes four vertical legs, and upper platform that attaches to a suspended seat with leg holes configured to hold a sitting child in a suspended position above the floor. A folding support frame holds the four legs in a fixed position when used as a walker but collapses into a folding configuration for compact storage. In one embodiment, the walker includes four X-shaped leg assemblies that enable the walker to collapse into a compact vertical configuration. In another embodiment, the walker has two X-shaped leg assemblies that enable the walker to collapse into compact horizontal configuration. In a third embodiment, the walker has four vertical legs and two collapsible side frames that enabling the walker to collapse into a vertical configuration.

The disclosed embodiments of the invention relate to a supporting apparatus and methods of using it. The supporting apparatus may include a frame member including an outer periphery and an inner periphery. The supporting apparatus may further include a first leg assembly and a second leg assembly, each configurable between a closed position and an open position. The supporting apparatus may further include a suspender that may be fastened to the frame member through a plurality of straps. The suspender may include a central member that may be positioned in a region enclosed by the inner periphery of the frame member.

A foldable mechanism is applied to locking an infant carrier and includes first and second mounts and a locking member. The second mount is pivoted to the first mount and has first and second mating portions. The locking member is movably disposed between the first and second mounts and is movable along an axial direction of a rotating axis of the first and second mounts to lock and release rotation of the first mount. The locking member has a positioning portion and a locking portion. The first mount is locked at a first rotating position or a second rotating position via movement of the locking member. The positioning portion is engaged with the first mating portion to lock the first mount at the first rotating position. The locking portion is engaged with the second mating portion to lock the first mount at the second rotating position.
