ABSTRACT:
A door structure openable from the right side or the left side has hinges at upper and lower positions on both sides of the door main body and door frame for permitting the door to be opened from either the right or the left sides. The hinges each have a shaft carrying member on the door main frame and an L-shaped hinge member having one leg pivotally mounted on the shaft carrying member for pivoting movement about an axis of opening movement of the door, and the other leg having a locking bolt projecting in a direction in which the door main body moves away from the door frame during opening of the door. The locking bolt has a lateral recess. The hinge further has a locking body on the door with a locking bolt receiving recess therein in which the locking bolt is received when the door main body is closed. A spring-loaded locking pin in the locking body is engagable in the recess for normally retaining the locking bolt in the recess and permitting the locking bolt and locking body to be separated by a door opening force.
