Aluminum alloy section for frame of e.g. interior door of building, has L-shaped element whose one branch comprises straight part slidingly fitted in passage of branch of another element and another branch comprises groove to receive seal

摘要

The section (10) has an L-shaped section element (12) whose branch (12b) comprises a straight part slidingly fitted in a straight passage (11bc) of a branch (11b) of another L-shaped section element (11). The passage is constituted of two flat segments (11ba, 11bb) that are parallel to each other and are connected perpendicular to another branch (11a) of the latter L-shaped section element. Another branch (12a) of the former element and the latter branch of the latter element respectively have profiled grooves (17) to receive corresponding seals (18) for supporting a door frame against a wall. An independent claim is also included for a frame of a door such as interior door of building or room, comprising hinges.
