  • Patent number: 6036625
    Abstract: A neck exercise apparatus has a cord and a head strap. The cord is formed from a highly elastic, rubberized tube and has a mounting strap secured to one end. A spring clip is secured to the opposite end of the mounting strap. A foam rubber pad surrounds each end of the tube. The head strap has a flexible, inelastic body with two hook and loop fastening straps on each end. The body also has several rings on an outer side and an elastic head support on an inner side. A variety of exercises may be performed with the apparatus. Prior to use, the mounting strap is inserted between a door and its inner door jamb so that the mounting strap is held in place. The user attaches the spring clip to one of the rings and the head strap is placed on the head. The head strap may be adjusted for fit by adjusting the position of the hook and loop flaps. With tension in the cord, the user then exercises the extension muscles of the neck by slowly tilting the head at the neck away from the door.
