Abstract
A buckle includes a male member having a pair of flexible arms mutually facing each other and disposed extending from a base part, and a female member to connect to the male member by coupling with the pair of arms. The male member has a flexible bridge connecting the pair of arms. The bridge is connected to an opposing face of each of the pair of arms facing the other arm. At the connecting portion where each of the pair of arms and the bridge are connected, the bridge is placed projecting toward the other arm from the opposing face on the arm following a tangential direction to a circle being centered on the base end of the arm and having a distance from the base end to the connecting portion as a radius.
Claims6
A buckle, comprising:
- a male member including a base part, a pair of flexible arms mutually facing each other, each extending from a base end at the base part, and a flexible bridge connected to and interposed between said pair of flexible arms and having an Omega form portion curved convexly toward said base part;
- and
- a female member connected to said male member by engaging with said pair of flexible arms;
- wherein said pair of flexible arms and said bridge are connected at connecting portions, and said bridge projects, at one connecting portion, inwardly from one of the pair of flexible arms along a first tangent line of a first imaginary circle centered on the base end and having a first radius from the base end to said one connecting portion to suppress a shear force on the connecting portion.
