Door base profile for a sectional door, or a sectional lifting and folding door with an escape door without a tripping threshold and preferably with a closing edge safety locking device whereat the door base profile a) is in the area of the vertical edges of the escape door separated over its entire cross section in order to enable installation of the escape door at the lock side and/or at the hinge side without tripping threshold, and b) exhibits at least one locking recess with an approximately U-shaped or approximately half-round cross section c) as well as at least one swiveling in or in it encompassed locking element (33, 35) on the other hand, d) where the locking recess and the locking element (33, 35) swiveled in or being encompassed by it when the sectional door or sectional lifting and folding door is lowered down and while the escape door is open or swiveling in are separated from each other at the lock side and at the hinge side of the locking element (33, 35) in each case by at least a gap providing sufficient contact tolerance, e) while the locking element (33, 35) being swiveled in in the locking recess or being encompassed by it while the escape door is closed and with the sectional door or sectional lifting and folding door to be lifted or being lifted is at the lock side and at the hinge side in each case in non-positive contact without gap in the locking recess and consequently connects the adjacent door base section (20, 21) non-positively with the escape door section of the door base profile, f) whereat at least one locking element and/or at least one locking recess exhibit in each case a cylindrical or prismatic structure with longitudinal axes being parallel to each other and with a variable but in longitudinal direction at least section by section constant cross section, whereby a non-positive connection between a locking element and at least one locking recess is caused by a swiveling movement of locking element inside the locking recess, and whereby the swiveling movement is preferably practicable up to a relative position with self-locking effect. a) is in the area of the vertical edges of the escape door separated over its entire cross section in order to enable installation of the escape door at the lock side and/or at the hinge side without tripping threshold, and b) exhibits at least one locking recess with an approximately U-shaped or approximately half-round cross section c) as well as at least one swiveling in or in it encompassed locking element (33, 35) on the other hand, d) where the locking recess and the locking element (33, 35) swiveled in or being encompassed by it when the sectional door or sectional lifting and folding door is lowered down and while the escape door is open or swiveling in are separated from each other at the lock side and at the hinge side of the locking element (33, 35) in each case by at least a gap providing sufficient contact tolerance, e) while the locking element (33, 35) being swiveled in in the locking recess or being encompassed by it while the escape door is closed and with the sectional door or sectional lifting and folding door to be lifted or being lifted is at the lock side and at the hinge side in each case in non-positive contact without gap in the locking recess and consequently connects the adjacent door base section (20, 21) non-positively with the escape door section of the door base profile, f) whereat at least one locking element and/or at least one locking recess exhibit in each case a cylindrical or prismatic structure with longitudinal axes being parallel to each other and with a variable but in longitudinal direction at least section by section constant cross section, whereby a non-positive connection between a locking element and at least one locking recess is caused by a swiveling movement of locking element inside the locking recess, and whereby the swiveling movement is preferably practicable up to a relative position with self-locking effect.
