摘要

The device has two construction units that are different in structure from each other. The construction units generate the restoring forces for automatic closing of the device, where both the construction units are accommodated in a moving part of the device, e.g. door or window held in closing position. Steel-plastic spring elements are accommodated within a door profile (2), where an elastic sealing material is used in the form of a silicone tube between a door panel and an opening frame.
