Device for closing an opening between two rooms or a facade opening of a building, the device comprising: - a plate shaped element; and - a first and a second pivot hinge (4, 4') provided on opposite sides of the plate shaped element for rotational hanging of the plate shaped element in the opening around a hinge axis S, said first pivot hinge comprising: ▪ a hinge housing; ▪ a rotation column provided to be attached to the wall of the door opening opposite the relevant side of the plate element, wherein the housing is attached to rotate around the rotation column such that the housing is rotatable around the rotation column from a closed position, in which the plate element closes the door opening, in a first direction to a first open position and/or in a second direction, opposite to the first direction, to a second open position; ▪ a first spring that extends into the hinge housing along the longitudinal direction of the hinge housing and which lends the self-closing function to the first pivot hinge; and ▪ a cam element (11, 31) that is part of the rotation column, and a first spherical ball that is pressed against the cam element by the first spring, and wherein the cam element is shaped so that it creates the support positions (113, 114, 115, 116) in which the first ball rests when the plate shaped element is in the open and closed positions, and that the first ball is pushed under the influence of spring pressure of the first spring nearly from each position varying from the support positions (113, 114, 115, 116) in the direction of the support position (113, 114) that corresponds with the closed position of the plate shaped element, wherein the support positions (113, 114) are formed by recesses (113, 114) in opposite surfaces of the cam element (11, 31), wherein in the recess (113, 114) of the cam element, consistent with the closed position of the plate shaped element, there is a damping element (41, 41', 41", 51) included for the support of the first spherical ball in the recess (113, 114) so that, when the first ball is pushed under the influence of the spring force of the first spring, it is pushed in the direction of the support position (113, 114) consistent with the closed position of the plate element, the damping element (41, 41', 41 ", 51) is deformed by the first ball and the first ball is slowed, and wherein the damping element (41, 41', 41", 51) defines an elongated opening through the cam element (11, 31) to receive an elongated connection means for connecting the elements of the rotation column to each other. - a plate shaped element;
