  • Patent number: 5022152
    Abstract: A golf-swing practicing apparatus having an improved reinforced support arm, and method of manufacturing such an arm. The arm is molded from a plastic material and has a central reinforcing rod extending along a substantial length thereof. The rod preferably extends to be flush with one end of the arm to maximize the reinforcing effect along the length of the arm, and to facilitate manufacture of the arm. A hollow tube is preferably included at one end of the arm, and engages the reinforcing rod. A shaft is received through the hollow tube for mounting the arm relative to a support base.

  • Patent number: 4741536
    Abstract: A golf-swing practicing apparatus is disclosed which indicates to the golfer when a well-executed practice swing has been made. The apparatus includes a base, a vertical shaft attached thereto, and a spinner which is rotatably mounted relative to the shaft. A support arm, having a golf ball-sized object secured at its free end, is pivotally supported relative to the spinner. This enables upward ascent of the golf ball-sized object relative to the spinner, and enables the spinner to maintain stable rotational movement during such ascent. The spinner includes an elongated channel formed in one of its ends. The channel is upwardly open and downwardly closed by a channel base. The channel enables a more intimate connection of the rigid support arm relative to the channel enabling the apparatus to take a greater number of hits from a golf club without failure, thus extending the life and improving operation of the apparatus.
