Claims

[Claims for Utility Model Registration] A base end of a main arm is fixed to a rotating shaft of a door closer body fixed to a door, and a front end of the main arm and a base end of a link are pivotally connected. , at the pivot joint between the bracket fixed to the door frame and the bifurcated tip of the stop joint, which is screwed to the link and formed into an integral rod, inside the bifurcated tip of the stop joint,
A stop cam is provided through a cam bushing having a first radial plane serration carved into an end surface, and a second radial plane serration that engages with the first radial plane serration is carved on the surface of the bracket opposite to the cam bushing. The first and second radial plane serrations are engaged and fixed so that they can be separated and the engagement position can be adjusted, and when the door is open, a coil spring built in the stop joint is inserted into the recess of the stop cam. In a door closer stopping device that maintains a constant opening state by engaging a ball that is biased by the ball, the distal end of the main arm is fixed at the pivot joint between the main arm and the link. an elongated hole is formed in the longitudinal direction, and the base end of the link has a threaded portion into which a tightening nut is screwed at the tip, and the intermediate part is pressed into contact with the peripheral edge of the elongated hole of the main arm. A pivot pin having a jaw portion is mounted rotatably around the axis, the pivot pin is inserted into the elongated hole of the main arm so as to be movable along the elongated hole, and a tightening nut is inserted into the threaded portion. A stop device for a door closer, characterized in that a pivot pin is screwed and tightened to the tip of the main arm so that its fixing position can be adjusted.
