OPENING AND CLOSING PLATE OF DOOR WITH BAR HAVING CYLINDRICAL OR POLYGONAL SECTION FORMED OF OPTIONAL MATERIAL, OR FRAME FOR SUPPORTING OPENING AND CLOSING PLATE OF DOOR

摘要

PURPOSE:To reduce frictional resistance by mounting bars having cylindrical or polygonal sections closely to the sides on which opening and closing plates of doors are touched or separated to each other in such a manner that they are rotated with rotating shafts parallel to the respective sides. CONSTITUTION:Rotating bars 1 having cylindrical or polygonal sections formed of optional materials are mounted on the mutual contact sides of opening and closing plate bodies 2, 2 of doors in the state parallel to the contact sides. Hence, when any substance is entered between the opening and closing plate bodies 2,2, the substance can be easily removed without reopening and reclosing the opening and closing plates of doors.
