Abstract

A sliding door with a door leaf, which is suspended from at least one carriage and guided to be displaceable along a roller rail profile disposed at a wall or at a ceiling. The sliding door includes a closing device, which is suitable to displace the door leaf into a closed position in a decelerated manner. The closing device is disposed at the door leaf and includes a first and a second spring-damper element, which are disposed to be counter-directional to each other. The second spring-damper element is suitable to displace the door leaf into an open position in a decelerated manner.
