<p>PURPOSE: A protective device of a hinged door is provided, which prevents fingers from being caught in a chink of a door, if pushing fingers, by the width of a primary shear preventer while a door is open and is deterrent to the action on closing a door by a large number of shear preventers bent by joint bodies when closing a door. CONSTITUTION: A protective device of a hinged door comprises the steps of; fixing a primary fastening plate (11) and a secondary fastening plate (12) on the direction of opening and closing by a hinge of a doorframe (1) and a door (2); forming a primary shear preventer (14), coupled to a primary fastening plate (11) by a primary joint body to be bendable, to be wider than the spread width of a doorframe (1) and a door (2) opened and closed at an angle of ninety degrees; forming a secondary shear preventer (16) coupled to a primary prevention fragment (14) by a secondary joint body to be bendable in width narrower than a primary prevention fragment (14); forming a third shear preventer (18) coupled to a secondary shear preventer (16) by a third joint body to be bendable in width narrower than a secondary shear preventer (16); forming forth, fifth shear preventers (20)(22), coupled between a third shear preventer (16) and a secondary fastening plate (12) by forth, fifth, sixth joint body (19) to be bendable, to be gradually narrower comparing to a third shear preventer (18).</p> |
