CN-121987013-A - Belt buckle

Abstract

A buckle includes a body having a top surface, a bottom surface, a first longitudinal end and a second longitudinal end, the first longitudinal end having a first lateral width, the second longitudinal end having a second lateral width greater than the first lateral width, a first opening through the body, a second opening through the body, and a lever between the first opening and the second opening. The buckle may also include a vertical wall and/or a retainer for securing the flexible length to the buckle after being connected to the buckle.

Description

Belt buckle Background Buckles are commonly used to releasably connect ends of flexible lengths such as straps, bands, ropes, cables, and the like. In some cases, a buckle may be used to releasably connect the ends of a single flexible length, thereby forming a loop, for example, for a belt, harness, or the like. In some cases, a buckle may be used to releasably connect ends of different flexible lengths, thereby forming a longer overall flexible length. The design goals of many buckles may be contradictory. On the one hand, it is desirable that the buckle be quickly and easily attached to and detached from each end. On the other hand, the buckle should reliably and securely connect the ends and minimize the possibility of accidental disconnection.
