The present disclosure discloses a wheel assembly structure and a child activity center. The wheel assembly structure includes a connection base and a wheel assembly that is deployable. The wheel assembly is pivotally connected to the connection base. The wheel assembly has a deployment state and a storage state. An adjustment mechanism is provided between the connection base and the wheel assembly. The adjustment mechanism is configured to switch the wheel assembly into the storage state from the deployment state. When the wheel assembly is in the deployment state, the wheel assembly is deployed to a first position to move the connection base. When the wheel assembly is in the storage state, the wheel assembly is stored to a second position to stably place the connection base. The wheel assembly structure has a simple overall structure, which facilitates production and lowers production costs.

An activity jumper for a child includes a base and two vertical supports operably connected to the base. The vertical supports extend upward from the base with each vertical support including two arms that extend away from the vertical support. A plurality of stretchable tension members are each operably connected to one of the two arms of one of the two vertical supports and a tabletop is suspended by the tension members, the tabletop having a top play surface and a central opening with a child seat disposed in the central opening. A method of storing an activity jumper is also provided.

A child activity center includes a tabletop having a top play surface and a bottom surface opposite the top play surface, and a central opening. A plurality of legs, are attached to tabletop and a lower platform is attached to the legs by a plurality of straps that are connected to the platform. A child seat is advantageously removably attached to the tabletop via over the central opening, in one form. Optional unique clips attach toys to the tabletop and one or more optional openings or windows in the tabletop allow an infant to see through the tabletop to the observe objects therebelow.

An entertainer for a child that is specifically configured and adapted for use in several operational configurations. The entertainer includes a plurality of legs and a tray for supporting a plurality of activity items for the child. A multi-functional plate is attachable to the legs to allow the entertainer to assume a seat support configuration. The multi-functional plate is detachable from the legs and positionable over the tray to allow the entertainer to assume a table top configuration.

An off-road walker is a support apparatus to assist or support an infant or toddler child to be mobile. The off-road walker includes a toy tray, a walker frame, an adjustable support, a plurality of casters, a plurality of frame guards, and a seat assembly. The toy tray supports objects for the child to interact with. The walker frame and the plurality of casters support the weight of the child and the toy tray through the adjustable support. The adjustable support allows the parent to set the distance the toy tray is displaced from the walker frame. The plurality of frame guards protects the walker frame from uneven terrain and can be positioned to assist the parent in maneuvering the off-road walker across the uneven terrain. The seat assembly supports the child and suspends the child from the toy tray and allows the child to rotate within the off-road walker.
