  • Patent number: 6253974
    Abstract: A buckle, provided with a detachable golf ball marker for allowing a wearer to easily carry such a marker while playing golf, is disclosed. In the buckle, the decoration part has a marker seat at its external surface and carries a first magnet on the seat. The golf ball marker has a second magnet with the magnetic polarity of the second magnet being opposite to that of the first magnet. The marker is thus magnetically and detachably seated on the marker seat. In another embodiment, a metal piece is externally mounted to a loop of the buckle, while the ball marker is magnetically attached on the metal piece. The buckle thus allows a golfer to easily carry the marker without forgetting it and also allows the golfer to devote himself to playing golf.
