ABSTRACT:
A safe having laterally rectractable door wings is disclosed. At either s of the door opening of a safe, a retraction space is provided extending both upwardly and downwardly, and in the rear, beyond the useful space of the safe. Each of two door wings is hinged to a movable supporting column which is guided at its top and bottom, by guide rollers running in guideways which extend obliquely inwardly to the rear of the safe. A column carries a plate firmly secured thereto and supports two track rollers which are mounted at locations spaced apart horizontally and vertically. Track rollers run along a guide rail, one on the upper and the other on the lower track surface thereof. The track surfaces have a convex cross-section. The guide rail extends exactly parallel to the guideways. The positions of the guide rail, guideways and track rollers are adjustable. A fixed guide roller engaging a groove on the underside of a respective door wing, forms the pivot axis for the wing. In its open position, the wing is received in the retraction space while extending perpendicularly to the closed door plane and closes the opening of the retraction space.
