摘要

The door frame (10) has two side limbs (11,12) whose two upper ends are interconnected to each other by an upper cross element (13). The connection points (V1,V2) of two support bars (15,16) are connected to the two lower ends of the side limbs, at an angle to the longitudinal axis of the upper cross element. A bottom cross element (14) is connected between support bars which is attached to the intersection points (S1,S2).
