Inwards opening door with full opening impaired by obstacles

摘要

In the first door position the door leaf, together with the length variable element (4), assume their closed position. They release the opening in their second position, in which the door cross-section is reduced by the position change of the length variable element in the opening region, into which the obstacle (6) protrudes. Thus the door can negotiate a full opening movement. Pref. the length variable element is foldable against the door opening direction and can be engaged by a stop. The leaf-element connection is at least one hinge (5).
