Description

  The present invention relates to a buckle for fastening a belt around a waist of a body.

  As a conventional belt buckle, for example, a buckle body in which a pair of support pieces are erected on both sides of a substrate and a first shaft support hole is formed in each support piece, and a pair of support pieces on both sides of another substrate And a first locking piece and a second locking piece projecting in opposite directions on both ends of the connecting plate, respectively. And a latching body provided with a first bearing projecting shaft and a second bearing projecting shaft on both side ends of both locking pieces, and the first bearing projecting shaft of the latching body serves as the first shaft bearing hole of the buckle body. The second support projecting shaft is pivotally attached to the second shaft support hole of the fastening body, and the front edge of the substrate of the buckle body extends farther forward than the first shaft support hole. The rear edge of the body board is extended rearward larger than the second shaft support hole so that each edge contacts the belt. Is the (e.g., see Patent Document 1).

According to this configuration, the number of parts of the buckle is small, and the configuration of the buckle is simplified, so that the buckle can be provided at a low cost.
However, on the other hand, in this configuration, one end of the belt is pressed by the buckle body against the first locking claw that is fixed in a state of standing substantially perpendicularly to the latching body, thereby By locking between the pawl and the buckle body and pressing the other end of the belt against the second latching pawl fixed in a state of standing substantially perpendicular to the hooking body by the fastening body, Since it latches between 2 latching claws and a fixing body, depending on the material and thickness of a belt, a 1st and 2nd latching claw may not bite into a belt well.

For this reason, locking protrusions are provided on the back surface of the buckle body substrate and the inner surface of the fastening body substrate, respectively, so that the belt can be securely locked. However, there is a drawback that the processing cost of parts increases.
In addition, the front end edge of the substrate of the buckle body needs to extend forward larger than the first shaft support hole, and the rear end edge of the substrate of the fastening body needs to extend rearward larger than the second shaft support hole. For this reason, the buckle must have a certain length, and the buckle cannot be made compact.
