(57) A frame gasket is described for cooking oven doors, which comprises a tubular profile
(1) with inner longitudinal cavity (2) and peripheral flange (3), having only one
butt joint, if any, even if the frame is of the four-side closed type. Coupling metal
inserts are provided for engagement into associate holes (12, 13) of the abutment
surface (14) about an over opening. In a first embodiment said inserts are either
L-shaped (5, 6), possibly of asymmetrical legs, with coupling tabs (9) for the corner
bent portions of the frame, or formed as elongated metal plates (8) with spring-like
prongs (9ʹ) for engagement into holes (13) of the rectilinear lengths. These prongs
(9ʹ) and the coupling tabs protrude from the profile through slots (11) formed by
removal of material. In a second embodiment the metal inserts (20) are all identical,
formed of a longitudinal plate length (21) to be fitted into the cavity (2) and fonded
at an end thereof with a hooked tab (22) projecting outwardly through a hole (27)
of the profile, there being provided two of said insert members (20) at each corner
region (25, 25ʹ) and one of them at each free end of the frame when it is open with
three sides.
