Window frame and/or opening frame

A fixed frame or opening frame (101;

• 102a, 102b), resulting from an assembly of joinery profiles, forming mullions (M) and cross-members (T) of said frame, ends of the joinery profiles of the mullions being assembled with ends of the joinery profiles of the cross-members, wherein:
• each mullion (M), each cross-member (T), or every mullion (M) and cross-member (T) of the frame comprises external joinery profiles (110, 111;
• 112, 113), and at least one internal assembly profile (116, 117), spacing the external joinery profiles, said external joinery profiles (110, 111;
• 112, 113) and said at least one internal joinery profile (116) having assembly portions, of complementary shape, mutually engaging, in order to ensure the assembly between said at least one internal joinery profile and said external joinery profiles, said at least one internal joinery profile (116, 117) being plastic and said external joinery profiles (110, 111;
• 112, 113), being metal,
• wherein said at least one internal joinery profile (116) has, in a section, a core (120) and two male portions (121, 122) that protrude laterally on either side of said core (120), which can be inserted into two complementary cavities formed respectively by said external joinery profiles (110, 111;
• 112, 113), said external joinery profiles (110, 111;
• 112, 113) forming two lateral flanks of the mullion (M) or of the cross-member (T), and
• wherein at least one of said at least one internal joinery profile (116) has at least two longitudinal recesses, with a closed section, internal to said at least one internal joinery profile (116), extending longitudinally to said at least one internal joinery profile (116), symmetrical with respect to a median plane of symmetry of said at least one internal joinery profile (116),
• said frame comprising:
• a length;
• at least one device for compressing (105;
• 106) comprising at least one pair of mechanical connections (1071, 1072) extending interiorly along an intermediary portion of said frame over all of the length of said frame, said intermediary portion being constituted by one of the cross-members (T) according to a first alternative, or one of the mullions (M) according to a second alternative,
• said at least one pair of mechanical connections (1071, 1072) extending in said two recesses along said at least one internal joinery profile (116), said at least one pair of mechanical connections having ends connecting supports of said device for compressing, said supports being integral respectively with said mullions (M), according to said first alternative, or with cross-members (T) according to the second alternative, on either side of said intermediate portion of the frame,
• said at least one pair of mechanical connections (1071, 1072) being solicited in traction in order to maintain under constraint of the ends of the joinery profiles of said intermediate portion of the frame (101;
• 102a;
• 102b) against the corresponding ends of the joinery profiles arranged on either side of said intermediate portion, belonging to said mullions (M), according to said first alternative, or to said cross-members (T) according to the second alternative, each mechanical connection of said at least one pair of mechanical connections (1071, 1072) being parallel to one another, arranged symmetrically with respect to a median plane (Pm) of said frame (101;
• 102),
• each mechanical connection of said at least one pair of mechanical connection (1071, 1072) being a rod comprising two ends with at least one of which being a threaded end intended to cooperate either by screwing with a tapped portion (108) of said support or by screwing with a nut (109) bearing against said support, in order to solicit said at least one mechanical connection in traction;
• and
• one or several brackets (103, 1041, 1042), (101;
• 102a;
• 102b), arranged respectively on one or several junction zones (Z) between the mullions (M) and the cross-members (T), at angles of the frame, said one or several brackets (103, 1041, 1042, 203, 204), with each having a first branch and a second branch extending along an angle with respect to the first branch, said first branch extending along one of the mullions (M), the second branch extending along one of the cross-members (T),
• wherein said supports of said at least one device for compressing include one or several of said brackets arranged respectively on the junction zones (Z) of two consecutive angles of said frame (101;
• 102), with each mechanical connection of said at least one pair of mechanical connection (1071, 1072) bearing on one of the brackets, at one end of said mechanical connection, or joining the two successive brackets by the two ends of said mechanical connection.
