  • Device for in place swimming
    Patent number: 4109905
    Abstract: A device to be used in a swimming pool for in place swimming is disclosed. This device consists of a foam rubber belt attached to a flexible cord. The belt is placed around the abdomen of a swimmer and the cord is secured to the side of the pool. The swimmer then practices swimming strokes in place against the restraint of the cord. The belt is water absorbent so that it acts as a cushion against the body of a swimmer. This prevents slipping and excessive pressure on the swimmer's body.
