Claim 0:
1. A dome cover assembly comprising:
a flange having a through-opening; and
a cover for closing the through-opening;
wherein the cover is rotatably mounted around an axis in relation to the flange, so that in a first rotational position, the cover is positioned above the through-opening and in a second rotational position, the cover is positioned so that the through-opening is free;
wherein one of the cover and flange has a reach-around element which, in a first rotational position at least partially encloses the other of the cover and flange on a side facing away from the one of the cover and flange, and the other of the cover and flange has a recess on the side facing away from the one of the cover and flange in a direction of the one of the cover and flange;
wherein the reach-around element and the recess are arranged such that, in the first rotational position, in a first distant position of the cover and flange, the reach-around element engages behind the recess or into the recess, and in the first rotational position, in a second closer position of the cover and flange, the reach-around element does not engage behind the recess;
wherein the recess at least partially does not extend up to a margin of the other of the cover and flange or the axis;
wherein the other of the cover and flange and the reach-around element are arranged such that the reach-around element passes over at least a section of the recess during a rotation from the first rotational position into the second rotational position;
wherein before the passing over, there is a greater distance between the side of the other of the cover and flange facing away from the one of the cover and flange than after the passing over; and wherein the other of the cover and flange has an indentation which is spit-shaped, wherein the spit opens in one direction that is in a plane parallel to a plane in which the through-opening is arranged, or the opening is arranged such that the reach-around element is moved through the through-opening into the indentation during the rotation of the cover in relation to the flange from the second rotational position and into the first rotational position, or the opening has an opening angle of less than 180°.
