发明名称 Swimmer's training device
摘要 A device and method for training a young child how to swim. The child is restrained in an open rectangular shaped cradle which is pivotally mounted for rotation in a floatable body. Pointed screws engage spindles to lock the cradle to the floatable body with the child in an upright position. The inclination of the child is adjusted in increments from an upright position toward a horizontal position to permit the child to practice the arm and leg movements of a swimmer. The floatable body is comprised of a cellular plastic body and a reinforcement attached to an upper surface of the body. In an alternate embodiment, the floatable body is comprised of a thin planar center member and front and rear floatable members. Outriggers and keels increase the overturning resistance of the device. Extensible hand cranks increase the effectiveness of the training device.
