Claims (1)
ークローザー本体内にコイルばねによつて一方向
に付勢されたピストンを収納し、このピストンの
中間部には平面形状ほぼく状の溝を備え、建物側
のドアー取付枠とドアークローザー本体との間に
介在されるリンクの一端に連結される軸をクラン
ク軸としてそのクランク部を前記溝に嵌入させ、
このクランク軸の回転により前記ピストンを摺動
させるように構成したドアークローザー。 A piston biased in one direction by a coil spring is housed in the door closer body attached to the upper end of the pivot side end of the door, and the intermediate portion of the piston is provided with a groove having a substantially dog-shaped planar shape. A shaft connected to one end of a link interposed between the building side door mounting frame and the door closer body is used as a crankshaft, and the crank part thereof is inserted into the groove,
A door closer configured to cause the piston to slide by rotation of the crankshaft.
