发明名称 Multipurpose float
摘要 A multipurpose float is provided which employs a rotatable bar attached to a main body of the float. Four bolts, each having a snap ring disposed at the bolt head, are located in four deep holes respectively formed in four sides of the main body. The rotatable bar can be set perpendicular to the main body to prevent the float from jumping out from between the thighs of a user. Further, a plurality of the floats can be combined to form a large sized floating bed.
