Description

  This invention can easily adjust the length of the waist belt in clothes such as beltless trousers and skirts. The present invention generally relates to a waist adjuster called a waist adjuster or a belt adjuster.

  Regarding conventional waist adjusters, various types of waist adjusters are known. Among these waist adjusters, for example, as shown in FIG. 18, an adjustment belt having juxtaposed adjustment protrusions protruding on one surface of the adjustment belt and an insertion portion through which the adjustment belt can be inserted are provided. In addition, the slider is formed with a locking protrusion that can be engaged with the adjustment protrusion on the inner surface, and in use, the slider inserted through the adjustment belt is manually moved up and down to lock the adjustment protrusion. A waist adjuster is known that can release the engagement with the protrusion and adjust the length around the waist.

Further, like the waist adjuster shown in FIG. 19, an adjustment belt having adjustment protrusions arranged on one side of the adjustment belt, an insertion portion through which the adjustment belt can be inserted, and a through-hole penetrating vertically are provided. Provided with sliders with slopes on both sides of the lower through-hole and locking projections that can engage with the adjustment projections on one side, and elastic legs that can slide the slopes on both sides. It is formed from an operation piece that can be inserted into the through hole, and an adjustment belt is inserted into the slider, and the operation piece is inserted from above the slider to engage and lock the adjustment protrusion and the locking protrusion to adjust the waist. At this time, by pressing the operation piece against the elastic force of the elastic leg portion, the engagement between the adjustment protrusion and the locking protrusion can be released, and the length around the waist can be adjusted. Waist adjusters are known.
