<p>In order to keep the braking moment in doors with a pivoting brake for the continuously progressive braking moment variation with different inclinations of the pivoting axis of the doors to the vertical within a determined range, rules given for calculating said braking moment, especially in relation to the braking moment thereof causing the door to be unintentionally closed and for an advantageous variation of said braking moment over a door pivoting angle.</p> |
