Sealing cap has handle for closing opening in wall, e.g. door leaf, where inner dome-shaped part is provided with shoulder, adapted to inner edge of opening which is to be locked, and another outer dome-shaped part is with another shoulder

摘要

The cap has knob for locking the opening (14) in a wall (10), e.g. door leaf, garage gate, frame cover, housing wall. An inner dome-shaped part (16) is provided with a shoulder (20), adapted to the inner edge (18) of the opening which is to be locked, and another outer dome-shaped part (22) is provided with another shoulder (26), adapted at the outer edge (24) of the opening which is to be locked. The shoulders are at a distance (38) to each other adaptable to the wall thickness (28). Two guide rails, which extend from the interior of the dome-shaped parts from the dome, slide in one another. The ends of the guide rails connect two transverse walls (34,36) with each other. The two transverse walls are at a distance to each other, which correspond to the distance of the shoulders. A pulling equipment (44), like screw with nut (40,42), moves the two transverse walls and both shoulders one on the other, and adjust the sealing cap at the edge of the opening.
