US 2015/0128503 A1 · UNIT FOR PREVENTING BODY PART OF USER FROM BEING CAUGHT IN DOOR

Abstract

The present invention relates to a unit for preventing a body part of a user from being caught. The prevention unit according to the present invention is to be coupled to a door and to a door frame, a floor hinge being connected to the lower surface of the door and the upper surface of the door being hinged onto a horizontal frame of the door frame such that the door can rotate about a hinge shaft, the door frame having the horizontal frame and a pair of vertical frames fixed to a wall. The prevention unit comprises: a unit for preventing a body part of a user from being caught in a door frame, the unit for preventing a body part of a user from being caught in a door frame having a door frame contact surface coupled to the vertical frame of the door frame and having a first concave curved surface having a first radius of curvature, the unit for preventing a body part of a user from being caught in a door frame having a cylindrical shape having a triangular cross-section or a quadrangular cross-section having at least one concave side, the unit for preventing a body part of a user from being caught in a door frame being coupled to the door frame such that the first concave curved surface faces the side surface of the door when the door rotates; and a unit for preventing a body part of a user from being caught in a door, the unit for preventing a body part of a user from being caught in a door having a door contact surface coupled to the edge of the front or rear surface of the door and having a first convex curved surface having a second radius of curvature smaller than the first radius of curvature, the unit for preventing a body part of a user from being caught in a door having a cylindrical shape having a triangular cross-section or a quadrangular cross-section having at least one convex side, the unit for preventing a body part of a user from being caught in a door being coupled to the door such that the vertical frame faces the first convex curved surface when the door rotates. According to the present invention, a body part of a user can be prevented from being caught in a door frame or a door, thus preventing or minimizing accidents and preventing or minimizing the waste of energy leaking through the space between the door and the door frame. Further, the prevention unit of the present invention is advantageous in that it can be coupled to all types of doors having various rotational axes or rotation radii in response to variations in the rotational axis of the door or to variations in the rotation radius of the door.
