  • Patent number: 7185598
    Abstract: A swim training and buoyancy assist device for an anchoring device has a resilient element and a resilient tether. The anchoring device is located at a certain location beside a swimming pool. The resilient element has a proximal end and a distal end. The proximal end of the resilient element is connected to the anchoring device. The resilient tether has a proximal end and a distal end. The proximal end of the resilient tether is connected to the distal end of the resilient element. The distal end of the resilient tether is connected to a swimmer. When the swimmer is connected to the resilient element and the resilient tether, the swimmer can only move a short distance in a certain direction and is buoyed up at a certain depth in the water so that the swimmer, especially a beginner, can practice swimming in a small area without the fear of drowning.

  • Patent number: 7175569
    Abstract: A swimming exerciser has a vertical support, an arm, a roller assembly, a resilient element, a belt, a resilient tether and a rope. The vertical support is mounted beside a swimming pool and has a pulley. The arm is hollow and is connect to and protrudes from the vertical support and has a distal end. The roller assembly is mounted moveably inside the arm. The resilient element is mounted inside the arm between the roller assembly the distal end of the arm. The belt is worn around a person's waist. The resilient tether is attached to the roller assembly and the belt and compensates for a swimmer's lack of movement through the water to hold the swimmer at a constant depth. The rope is connected to the roller assembly, reeved through the pulley and connected to the belt to hold a swimmer in a fixed position when swimming.
