  • Patent number: 6711788
    Abstract: A modified structure of a telescopic belt buckle includes a spring compartment in the belt buckle body, and a latch located at the end of the spring to link the head of the belt, which is allowed to slide along the compartment and reach the belt fastening the human body with specific length for extension. As both the thickness of the belt equals the space taken by the spring, the compartment is thus provided with enough space for telescopic movement of the most slim and simple buckle.
