发明名称 Swimming apparatus
摘要 A swimming apparatus wherein an endless, elongate, rope-like belt is looped once around the waist of the swimmer and over a suitable guide which permits the belt to slide back and forth as the swimmer rolls alternately one way and then the other in performing the customary swimming motions. A ring receives the loop at the swimmer's waist and keeps it from slipping along the swimmer's body without interfering with the swimming action. A stationary support at the water's edge carries the guide and holds it yieldingly retracted to prevent the belt from tangling in the swimmer's legs.
