• a battery-powered electric motor 18 with a motor shaft configured to wind the elongated drive element 14 and unwind it from the driver 11 can be used instead of the deflection pulley 18. In this case, the elastic element 12 is omitted.
• a combination of elastic elements 12 and electric motors 18 is also conceivable.
• Fig. 1 The emergency opening device 10 is shown in a ready state.
• the elastic element 12 is pre-tensioned, i.e., the coil spring is stretched and thus stores tension energy.
• the locking element 15 is engaged, preventing rotation of the driver 11, and the elongated drive element 14 (toothed belt) runs over the driver 11 and is connected to the elastic element 12. (spring) is connected, the spring cannot relax and is held in the tensioned state. Since the detachable connecting elements 13 (bolts) are in Fig. 1 Furthermore, when the actuator 11 is in the disengaged position, it is decoupled from the drive device 110.

• Fig. 1 in a position after the emergency opening device 10 has been triggered. This could be, for example, a situation following a power failure or a technical issue with the drive device 110, which prevents the lifting gate 100 from being opened electrically by the drive device 110.
• the detachable connecting elements 13 (bolts) are inserted and the driver 11 is thus coupled to the drive device 110. Furthermore, in the Fig. 2 the locking element 15 (pawl) is pivoted into a position which allows a rotational movement of the outer section of the driver 11 around the inner section of the driver 11, i.e. in which the driver 11 is not locked and can therefore rotate around the inner shaft 111.
• the releasable connecting elements 13 were inserted into the recesses 112 in the toothed disc 114 before the pawl was released, thus coupling the driver to the drive device 110 so that a rotary motion of the driver 11 could be transmitted to the drive device 110.
• the locking element 15 was moved into the released position. This allows the elastic element 12 (spring) to relax and release the previously stored tension energy.
• the spring then drives the toothed belt 14 and thus rotates the driver 11 around the inner shaft 111. Since the driver 11 was previously coupled to the drive device 110, this rotary motion is transferred to the The inoperative drive device 110 is transmitted, thereby raising the gate leaf 110 and opening the overhead gate 100.
• the electric motor 18 When using a battery-powered electric motor 18 instead of the deflection pulley 18 and the elastic element 12, the electric motor 18 is simultaneously electrically connected to the battery via a mechanical switch and thus activated when the locking element 15 is released. This causes the electric motor 18 to wind the elongated drive element 14 onto its motor shaft and unwind it from the driver 11, thereby driving the driver 11.
• the emergency opening device 10 can also be used in a lifting gate 100 that is equipped with a foil-like curtain as the gate leaf 120.

• the driver 11 is then located directly next to the lateral bearing (the side walls) of the hollow shaft 111 and can be directly connected to it, for example, by incorporating the recesses 112 into these lateral bearings.
• a lifting gate 100 may also have a second emergency opening device on the opposite side of the drive device 110, for example, to increase the opening speed.
• a second emergency opening device can be operated either separately or together with the first emergency opening device.
• the emergency opening device 10 can be actuated, for example, as described above, by means of an emergency lever 17.
• This emergency lever 17 can, for example, be connected to the releasable connecting elements 13 and the locking element 15 via cables. Furthermore, it can also be provided that the emergency lever 17 mechanically releases a brake integrated into the drive device 110 before the lifting gate finally opens.

• the emergency opening device 10 has several successive operating positions, the sequence of which corresponds to the intended sequence of steps for opening the overhead gate 100 with the emergency opening device 10. Specifically, in a first operating position, the releasable connecting elements 13 can be extended (thus disengaging the driver 11 from the drive unit 110) and the locking element can be engaged.
• the releasable connecting elements 13 can first be retracted, thus coupling the driver 11 to the drive unit 110.
• the locking element 15 can then be released/disengaged, and in a fourth position, a brake on the drive unit 110 can be released, thus opening the overhead gate 100.

• Fig. 3 is a flowchart of a process 200 for opening a lifting gate 100 with a previously inserted Fig. 1 and 2 described emergency opening device 10.
• the procedure 200 begins at step 201 with the rotationally fixed connection of the driver 11 to the drive device 110.
• the detachable connecting elements 13 are pushed into the recesses 112.
• step 202 the locking element 15 is moved into the released position to allow rotation of the driver via the tension energy of the elastic element 12 (or via the drive power of the electric motor 18 in corresponding versions).
• the drive device 110 does not include an internal brake, the procedure ends here and the lifting gate 100 opens.

• the emergency opening device 10 After the emergency opening device 10 has been triggered, it can be reset to its ready state by the drive device 110 as soon as the drive device 110 is operational again. To do this, the drive device 110 simply needs to be operated in reverse until the elastic element is pre-tensioned again. Then, the locking element 15 is re-engaged and the driver 11 is decoupled from the drive device 110 by pulling the releasable connecting elements 13 out of the recesses 112.
