DOOR, IN PARTICULAR A FIRE-PROOF DOOR, WHICH CAN OPTIONALLY BE USED TO ABUT ON THE RIGHT-HAND OR ON THE LEFT-HAND SIDE
The invention relates to a door with a frame (3) and a door leaf (2) optionally fitted to abut on the right-hand or the left-hand side, and provided on the longitudinal side regions and at least in one of the flank regions with a fold which covers when closed the gap to the frame (3), when viewed from the flank pointing in the opening direction. Said door leaf (2) is connected to the frame via hinges (5), each having at least three hinge blades (8, 9) which a hinge bolt (4) traverses. Sliding rings (12) are preferably arranged in particular to rotate in unison with those end surfaces of the hinge blades which face each other. The design of said door is such that for the purpose of particularly simple manipulation for the required height displacement of the door leaf (2) in the frame (3), the door leaf (2) is formed to be displaceable in relation to the frame (3) by approximately up to the height of one flank fold of the door leaf in the region of the hinges (5) in the longitudinal direction of the bolt, and can be fastened, optionally in one of the displacement end positions, to pivot about the hinge bolts (4) without dismantling or altering the hinge parts (4, 8, 9).
