METHOD AND ANGULAR PART FOR CONNECTION OF ALUMINIUM PROFILES FOR THE CONSTRUCTION OF A FRAME OF A DOOR OR A WINDOW AND RELATED ITEMS, AND ALUMINIUM PROFILES CONNECTED BY THE SAME PART.

摘要

A method and angular part are described for the invisible internal connection of aluminium profiles at absolutely right angles where no opening of holes is required for the construction of doors, windows and related items. The proposed angular part bears at its two ends a rectangular plate which constitutes the main body of a terminal blade bent at an angle of 45 degrees for the connection with a hole for passing a bolt and an end bent at an angle of 90 degrees which is used as a guide for the termination of the sliding of the main body of the part within grooves defined with parallel ribs on either side of a flat internal surface of the profile, which is specially shaped and suitable for co-operation with the proposed angular parts for connection. During the joining of two lengths of profile at right angles the proposed angular parts and entered on either side, they slide until they come into contact with the terminal blades for connection to the joining edge of the profile and that are grasped there with a suitable bolt which passes via the holes of the terminal connection blades.
