Woodwork for receiving roller shutter, has door frame made of aluminum alloys, and guiding elements with reduced gap between median planes of guiding elements, where gap adapts to section or thickness of leaf frame in aluminum alloys

摘要

The woodwork has two cross beams, a door frame (14) with two posts (18), and two door leafs sliding with respect to the door frame. The leafs comprise leaf posts and a leaf cross beam for forming a frame surrounding a transparent surface. The door frame comprises two rail shaped guiding elements (28) along which the leafs slide, and is made of aluminum alloys. The guiding elements have a reduced gap between longitudinal median planes (29) of the guiding elements, where the gap adapts to a section or a thickness of the leaf frame in the aluminum alloys.
