Document Type and Number:
WIPO Patent Application WO/2013/169062
Kind Code:
A1
Abstract:
The present invention relates to a unit for preventing a body part of a user from being caught in a door. 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 a horizontal frame and a pair of vertical frames fixed at a wall. The prevention unit comprises: a unit for preventing a body part of a user from being caught in a doorframe, the unit for preventing a body part of a user from being caught in a doorframe having a doorframe contact surface coupled to the vertical frame of the door frame and having a first curved concave surface having a first radius of curvature, the unit for preventing a body part of a user from being caught in a doorframe having a cylindrical shape having a triangular cross-section or a square cross-section having at least one curved concave side, the unit for preventing a body part of a user from being caught in a doorframe being coupled to the door frame such that the first curved concave 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 curved convex 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 square-cross section having at least one curved 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 curved convex 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 doorframe. 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 turning radii in response to variations in the rotational axis of the door or to variations in the turning radius of the door.
