Abstract
In door hardware, the handle 1 on the inside of the door and the handle 2 on the outside of the door are interconnected via respective halves 21 and 22 of a handle pin. The door handles can be secured by means of set or clamping screws 25,26 with the handle halves. Moreover there are two escutcheon plates 6 and 7 which, following the mounting of the hardware to a door panel, are clamped against the door panel. The setscrew 26 for the handle 4 on the outside of the door is arranged in the region behind the outside of the escutcheon plate 7 on the outside of the door, namely preferably in such a way that it is invisible and inaccessible from the outside. The cooperation of the setscrew 26 and the handle pin half 22 permits preferably a finely stepped axial adjustment of the handle pin half with respect to the handle 2 on the outside of the door. The door handle is secure against dismantling from the outside and remains operable in the event of fire.
