The door-leaf part (14) has two insertion pins (13) joined at each end by a hinge pin (15). The frame part (23) is mounted on the leaf part so as to swivel on the hinge pin. The insertion pins of the leaf part are contained in sleeves (9) in a door leaf (1). The internal diameter of the sleeves in one part (12) is larger than the external diameter of the insertion pins. The pin-sleeves, on their ends facing the door leaf, have an internally threaded part (11) in which is screwed an externally threaded part (16) formed to match on the door-leaf side ends of the insertion pins. The sleeves may be pressed into the door leaf, whilst the ends of the sleeves may be inserted into the door leaf, closed by caps (10). |
