A closure element comprises two sash elements (1, 2) which are mutually adjacent or overlap in a closure plane and which each have a filling piece (3). The sash elements (1, 2) can be moved by a mechanism connected to a drive for opening in different planes parallel to the closure plane, and once a particular plane has been reached the first sash element (1) can be slid parallel to the closure plane and in front of the second sash element (2). |
