发明名称 Toy hoop
摘要 The present invention is a toy hoop for use by a person. In one embodiment of the present invention, the toy hoop comprises a hoop member having first and second end portions and a first channel adapted to receive flow of a first medium such as water. The toy hoop further comprises an interconnect member having first and second end portions adapted to connect the first and second end portions of the hoop member. The interconnect member comprises a first channel in communication with the first channel of the hoop member to allow the first medium to flow there thru. Each of the first and second end portions have an outside surface and an inside surface. The inside surfaces are downwardly tapered to provide laminar flow of the first medium thru the first channel of the hoop member. The toy hoop further comprises a first inlet port in communication with the first channel to allow the person to adjust the volume of the first medium and therefore the mass of the hoop member and the centrifugal force. The toy hoop further comprises a first plug member adapted to engage with the first inlet port member to seal the first channel. In use, the person may fill the first channel of the hoop member with a desired volume of medium to obtain a desired mass and centrifugal force.
