Abstract: A slide adjuster includes a belt having engagement grooves in a form of saw teeth, and a buckle for receiving the belt therein in a forward direction and preventing the belt in the buckle from moving in a backward direction. The buckle includes a buckle body, and an operating plate disposed above a bottom plate and including an engagement claw projecting toward the bottom plate to engage one of the engagement grooves of the belt. The buckle body further includes restricting members projecting inwardly from two side plates thereof, and the operating plate includes recessed portions for receiving the restricting members therein without connecting thereto to prevent an accidental pressing force from being applied in a vertical direction to the operating plate.

Abstract: A synthetic-resin made and single-peace structured slide adjuster in which a buckle section has an appearance not so visible. In the slide adjuster for a belt and a buckle, an engagement claw of the buckle is engaged in an engagement groove having a form like saw teeth formed on an external surface of the belt. In the engaged state the belt can move forward but can not move backward. The buckle comprises a buckle body having a bottom plate and a ceiling frame opposite to each other and two side plates for connection between the bottom plate and the ceiling frame and also having an internal space for insertion of the belt; and an operating plate provided in the horizontal posture inside the ceiling frame and having an engagement claw provided on a bottom surface of an end portion thereof and capable of being engaged in the engagement groove of the belt and also having a pressed section provided at another end portion thereof for releasing the engagement.

Abstract: A band has an engaging projection part at one end, and an engaging grooves at the other end to adjust the connection in an annular shape. The band is movable forward but not movable backward relative to the other under the condition that the engaging projection part is locked to the engaging recessed part. A pair of hook parts capable of pulling both end parts by fingers of one hand is installed on both end parts. A buckle connected to the band includes a buckle main body having a bottom plate, a roof frame, and side plates for connecting the bottom plate to the roof frame. An operating plate is installed horizontally inside the roof frame, and has an engaging claw engageable with the band engaging grooves and a pressing part. The buckle and the band is made simple, and easily attached together.
