Belt Buckle

Abstract

PROBLEM TO BE SOLVED: To prevent backlash in a joint state of a belt and to reliably push a male member through a female member when canceling the joint state with regard to a belt buckle for joining the belt. SOLUTION: A lock member 40 includes a cancel button 90 facing through an opening 32 provided at the female member 30 and cancels an engagement state between an engaging part 100 and an engaged part 80 by being urged toward the opening 32 and pushing the cancel button 90 against the urging force. Either one of the engaging part 100 and the engaged part 80 (for example, the engaging part) is provided with a pressing spring 102 abutting on the other one of the engaging part and the engaged part (for example, the engaged part 80) in the engagement state of both parts, warps to accumulate a spring force, and presses an insertion piece 60 of the male member 20 through the insertion port 31 of the female member 30 by the accumulated spring force, and a hold part 2101 for pinching the other part (for example, the engaged part 80) together with the pressing spring 102.

Description

technical field [0001] The present invention relates to a buckle for connecting seat belts, and more particularly to a buckle capable of preventing loosening of the connection state of the seat belt and reliably pushing out a male part from an insertion opening of a female part when the connection state is released . Background technique [0002] Conventionally, there is known a buckle in which a release button is slidably supported in the hollow interior of a female member, and a claw portion of the release button is inserted into a locking hole of a male member inserted from an insertion port of the female member (for example, refer to the patent document The paragraph numbers of 1 are 0047, 0051, 0057, figure 1 and Figure 8 ). [0003] Patent Document 1: Japanese Patent No. 4302038 [0004] However, in the above-mentioned conventional buckle, the claw portion of the release button is simply inserted into the locking hole of the male member, so there is a problem that...

Problems solved by technology

[0004] However, in the above-mentioned conventional buckle, the claw of the release button is simply inserted into the locking hole of the male part, so there is a problem that the mating part of the two may loosen in the hollow interior of the female part.
