<p>PURPOSE: A unit for preventing a hand of a user from being caught in a door is provided to minimize the waste of energy leaking through the space between a door and a doorframe. CONSTITUTION: A unit for preventing a hand of a user from being caught in a door comprises a first unit(300) for preventing a hand of a user from being caught in a doorframe and a second unit for preventing a hand of a user from being caught in a door. The first unit has a doorframe contact surface(312) and a concave curved surface(314). The doorframe contact surface is fixed to a vertical frame of a doorframe. The concave curved surface faces the side surface of a door when the door is rotated. The second unit has a door contact surface and a convex curved surface. The door contact surface is fixed to the edge of the front surface or rear surface of the door. The convex curved surface faces the vertical frame of the doorframe when the door is rotated.</p> |
