| 摘要 |
<p>The invention relates to a device and a process for operating an automatic door closer having a connection lever (1) which engages swivellably on the door and a motor-driven device (3) which is controlled by the connection lever (1) and endeavours to restore the door moved into the open position, the connection lever (1) extending into the motor-driven device (3) by means of a rotation sheath (2) connected fixed in terms of rotation to the connection lever (1), which motor-driven device rotates freely during the opening movement of the door within the motor-driven device (3) and activating the motor-driven device (3) during its rotational movement, which device endeavours to restore the rotation sheath (2) into its initial position, the operational connection between the motor-driven device (3) and the rotation sheath (2) being timeable for the purpose of restoring the rotation sheath (2) into its initial position and the connection between the motor-driven device (3) and the rotation sheath (2) occurring with intermediate connection of a spring-elastic means (14). <IMAGE></p> |
