  • Patent number: 6578241
    Abstract: An inward-wind type belt buckle in which the rear end portion of a belt is wound between the front end portion of the belt and the clothes is disclosed. With the belt buckle, since the upper marginal portion of the side wall of the lower channel is not exposed forwardly, various types of patterns or designs can be expressed on the front plate of the belt buckle, thereby providing more elegant and refined belt buckle. In addition, since the hinge pin of the fixture for fixing the belt is not exposed outwardly, its stability in use is more improved.
