Abstract
A buckle includes a male member including a base part and a pair of flexible arms extending from the base part, and a female member including an insertion hole formed at one end portion thereof. The pair of flexible arms is inserted in the insertion hole. The base part contacts the one end portion when the male member engages the female member. An outer face portion of each of the pair of flexible arms has a shape curving outwardly at a middle portion thereof relative to an insertion direction of the pair of flexible arms, and the pair of flexible arms is provisionally fastened to the female member when the pair of flexible arm is inserted in the insertion hole.
Claims9
A buckle, comprising:
- a male member including a base part and a pair of flexible arms extending from the base part, each arm having an arm-latching part formed at a middle portion thereof and convexed laterally outwardly therefrom, a front side raised part protruding upwardly from a front surface thereof and a rear side raised part protruding downwardly from a rear surface thereof, and
- a female member including an insertion hole formed at one end portion thereof, guide grooves extending inside thereof from the insertion hole, and guide faces arranged at the one end portion to partially define the insertion hole, the pair of flexible arms being inserted in the insertion hole,
- wherein the pair of flexible arms has a width between the arm-latching parts perpendicular to an insertion direction of the pair of flexible arms, the width of the arm-latching parts being larger than that of the insertion hole such that when the pair of flexible arms is inserted in the insertion hole, the arm-latching parts contact the guide faces, then the pair of arms is bent in a direction approaching each other to increase an external force, thereby the pair of flexible arms is provisionally fastened to the female member, and after the arm-latching parts pass the guide faces, the front and rear side raised parts are guided through the guide grooves in the insertion direction, and the base part contacts the one end portion when the male member engages the female member.

- a leading end portion of each of the pair of flexible arms protrudes in the insertion direction relative to the front and rear side raised parts such that an outer face portion between the arm-latching part and the front and rear side raised parts, in each of the pair of flexible arms, is convexed in the insertion direction,
- a leading-end-positioning rib is arranged on each of the front surface and the rear surface of the leading end portion to protrude therefrom, and
- a base-end-positioning rib is arranged on each of the front surface and the rear surface of a base end portion adjacent to the base part to protrude therefrom, to prevent a displacement of the male member relative to the female member.
