Patent ID: 8099903

Claim:
Door system comprising: at least one door leaf for closing off an entrance opening, wherein the entrance opening is at least defined by a first doorpost and a second doorpost, wherein the door leaf has a first side and a second side, wherein in a situation where the entrance opening is closed off, the door leaf is located between the first and second doorposts, the first side of the door leaf is situated near the first doorpost and the second side of the door leaf is situated near the second doorpost; a displacement system coupled to the door leaf and supported relative to the first and second doorposts for moving the door leaf between a first position closing off the entrance opening and a second position providing access to the entrance opening, characterized in that: the displacement system comprises a suspension rod having two suspension points on the suspension rod, wherein the door leaf is connected to an organ supporting the door leaf on the suspension rod, the organ being movable between the two suspension points, wherein a first of the suspension points is situated at a greater distance from a plane passing through the first and the second doorposts than a second of the suspension points, the door leaf being supported by the organ at a set non-parallel angle of the door leaf relative to the suspension rod such that the angle of the door leaf relative to the suspension rod does not change during translation of the organ and door leaf along the suspension rod; a fixed rotation axis of the suspension rod is provided which is situated at a distance from the second side and at or adjacent the first suspension point, the fixed rotation axis being stationary relative to the first doorpost and the second doorpost, the door leaf, the movable organ and the second suspension point being rotatable around said fixed rotation axis; and the displacement system comprises a track system so as to be able to move the door leaf from the first position to the second position in two phases, wherein the track system as a consequence of a translation of the movable organ from the first position to the second position, in the first phase determines a rotation of the door leaf around the rotation axis for making the second side of the door leaf move away from the plane to beyond the second doorpost, and the track system in the second phase determines a rotation of the door leaf around the rotation axis in the opposite direction of the first phase by a displacement of the organ from the first suspension point in the direction of the second suspension point.
