METHOD FOR JOINING AND COUPLING A COUPLE OF PROFILES OF DIFFERENT MATERIALS, CONSTITUTING THE LEAF AND THE FRAME OF AN EXTERNAL FIXTURE

摘要

The present invention relates to an innovative method for jointing and coupling sectional elements (1- 2) to be used for the production of closing fixtures in the residential, public, commercial, and industrial building sector. The mutual joining of the two sectional elements (1-2) constituting the node (F) of the external closing fixture is obtained for the mobile leaf (7) through a jointing means constituted by the self-tapping screws (6) normally used for constraining the rail or plate (3) of the perimetral hardware. The self-tapping screws (6) constrain said two sectional elements (1-2) through the protuberances (4-5) with which the sectional elements (1-2) themselves, respectively, are provided. The mutual joining of the two sectional elements (1-2) constituting the node (F) of the external closing fixture is obtained for the frame (8) through a jointing means constituted by the self-tapping screws (6) normally used for constraining the closing striker blocks (18) of the perimetral hardware. The jointing is obtained by following an innovative method for insertion of the multiglazing pane (48) by pressing together said sectional elements (1-2) constituting the mobile leaf (7). The internal hide-away hinges (10) are mounted within the node of the frame (F), thus enabling preferred lengthening of the thermally insulating profile.
