US Patent 7780500 Portable ride-on bouncing and spinning toy

A ride-on activity device is disclosed, wherein the device includes a seat, a base and a connector for movably connecting the seat relative to the base. The connection between the seat and the base allows multiple degrees of freedom such that the seat is capable of bouncing and rotating relative to the base. The connection between the seat and the connector includes a rotation safety mechanism that allows rotation at the connection when the seat is occupied by a user and prevents rotation at the connection when the seat is unoccupied. Furthermore, the connector includes a resilient member that allows the seat to bounce vertically relative to the base.
