发明名称 Barrier device for children
摘要 A struggling barrier for children includes a semirigid wall for blocking struggling movements which is attached to a flexible sheet for receiving sitting body weight of children. The method of sitting on the flexible sheet transfers body weight force to the attached wall thereby causing the flexible and movable device to become a semirigid and difficult to move barrier device.
