Doors and windows on roller bands suitable for removal and reuse

摘要

Doors and windows become usable for installation, removal and reuse in that roll-up door leaves and window wings are guided on roller bands at the top and bottom during opening and closing. To open and close the doors or windows, therefore, there is no need for door frames and window frames, their function being performed, in principle, by the roller bands. Various fixing devices make it possible to adapt the installation and, after their release, the removal of the doors and windows to the site conditions, without the installation or removal resulting in damage, for example to the masonry. An adaptation to different clear widths is possible to a limited extent. The locking of the door or window is carried out without attaching a fitting to the masonry, but by means of a fitting which is integrated in the door or window and which also allows fixing in a specific opening position.
