US 6,205,630 B1 · Unit of buckle component members and buckle

Abstract

Before mounting to an anchor plate, a holding block is connected by a plurality of connecting portions to a button so as to be formed integrally with the button. A pair of connecting portions among the plurality of connecting portions is comprised of a button-side connecting portion and a holding block-side connecting portion, and the button-side connecting portion and the holding block-side connecting portions are joined together by a minimum sectional area portion which intersects, at an angle of inclination of 45 degrees, a direction in which the button slides. The minimum sectional area portion is made substantially perpendicular to the direction of tensile stress acting during assembly, and therefore, a crack is formed in the minimum sectional area portion along the shortest possible length of the minimum sectional area portion when the above-described pair of connecting portions is broken. Due to the above-described structure, a unit of buckle component members which can be assembled by a small sliding force and which prevents falling-off of debris during assembly, and a buckle using the unit are obtained.

Dependent claims

A unit of buckle component members, comprising:

plural members which are formed integrally with each other and are provided so as to be mounted to a buckle main body by sliding the plural members along an axis (A) with respect to the buckle main body;
and
connecting portions by which said plural members are connected together to form a integrated main body of the unit of buckle component members and which respectively include minimum sectional area portions formed along a line that transversely intersects said axis (A) in which the main body of the unit buckle component members slides with respect to the buckle main body.

A buckle comprising:

a holding member for holding a lock member, which is engaged with a tongue plate inserted up to a predetermined position so as to make it impossible to pull out the tongue plate, such that the lock member is movable between a position where the lock member is engaged with the tongue plate and a position where the engagement of the lock member and the tongue plate is released;
a release operating member which operates the lock member engaged with the tongue plate so as to move the lock member in an engagement releasing direction;
and
a mounting member to which said holding member is fixed and to which said release operating member is mounted in a slidable manner,
wherein, before said holding member and said release operating member are assembled with said mounting member, said holding member and said release operating member are integrally connected via connecting portions, to thereby form a unit of buckle component members which can be mounted to said mounting member by sliding along an axis (A) with respect to said mounting member, and the connecting portions respectively include minimum sectional area portions which are each formed along a line which transversely intersects the axis (A) of the sliding direction of the unit of buckle component members.
