Diese weist einen reversibel arbeitenden Elektromotor auf, welcher über eine Kupplung mittels eines Spindelantriebs einen Riegel antreibt. Aufgrund ihrer Dimensionierung und Konstruktion eignet sich eine derartige Vorrichtung nicht zum Einbau in eine übliche Tür oder in einen üblichen Türrahmen eines Gebäudes.DE 36 31 043 C1 describes a device especially described for motor vehicle door locks. This has a reversible electric motor, which via a coupling by means of a spindle drive drives a bolt. Because of their dimensions and Such a device is not suitable for construction for installation in a standard door or in a standard Door frame of a building.
Aus der DE-G 94 03 769 ist ebenfalls eine Vorrichtung bekannt, bei welcher der Sperriegel mittels eines reversibel arbeitenden Elektromotors über eine mit einem Ende im Riegel befestigte biegsame Welle angetrieben wird, wobei das andere Ende der biegsamen Welle mittels eines Gleitstücks in einen an der Motorwelle ausgebildeten Spindelantrieb eingreift.From DE-G 94 03 769 is also one Device known in which the locking bolt by means of a reversible electric motor via one with one End of the flexible shaft fastened in the bolt is driven, the other end of the flexible shaft by means of a Slider in a spindle drive formed on the motor shaft intervenes.

Zustand. Der Gleichstrom-Elektromotor 4 ist im Gehäuse
1a der Stelleinrichtung 1 befestigt. Er weist eine Motorwelle
22 auf welche quer oder senkrecht zur Längsachse des
Sperriegels 3 ausgerichtet ist und welche über ein Getriebe
19 mit dem Sperriegel 3 verbunden ist. Das Getriebe
19 wandelt die Drehbewegung des Motors 4 über eine Spindel

4 auf.The
Das Zahnrad 24a mit dem kleineren Durchmesser überträgt
über unter Umständen mehrere zwischengeschaltete weitere
Zahnpaare 24 und 25 des Getriebes 19 die Drehbewegung zu dem

des Riegels um.The
In dem in Figur 2 beschriebenen Ausführungsbeispiel für
eine erfindungsgemäße Riegelbetätigungsvorrichtung weist
das Getriebe 19 zwei weitere Zahnradpaare 24 und 25a auf.
Dabei sind die einzelnen Zahnräder 24a, 24b bzw. 25, 25b
der Zahnradpaare 24 bzw. 25 jeweils drehfest auf je einer
gemeinsamen Drehachse gelagert und weisen jeweils unterschiedliche
Durchmesser und Zahnzahlen auf. In the embodiment described in Figure 2 for

Das größere Zahnrad 24b des ersten Zahnradpaares 24 wird
dabei durch das kleiner Zahnrad 20a des motorseitigen Zahnradpaares
20 gekämmt und nimmt somit die Motordrehbewegung
auf. Diese Drehbewegung wird im Getriebe 19 dadurch weiter
geleitet, daß das kleinere Zahnrad 24a des ersten Zahnradpaares
24 das größere Zahnrad 25b des zweiten Zahnradpaares
25 kämmt. Das somit in Rotation versetzte zweite
Zahnradpaar 25 überträgt die Drehbewegung an das riegelseitige
Zahnrad 21, indem das kleinere Zahnrad 25a des zweiten
Zahnradpaares das riegelseitige Zahnrad 21 kämmt.The larger gear 24b of the
Am riegelseitigen Zahnrad 21 bzw. an dessen Drehachse ist
eine Nase 23 derart angebracht, daß ein Stellungssensor 5
bei voll ausgefahrenem Riegel 3 durch diese Nase 23 betätigt
wird und somit ein Signal an die Alarmzentrale 10
der Einbruchmeldeanlage abgegeben wird und daß ein Stellungssensor
6 bei voll zurückgezogenem Riegel 3 betätigt
wird und somit ebenfalls ein Signal an die Alarmzentrale
der Einbruchmeldeanlage abgegeben wird. Es kann eine weitere
Nase vorgesehen sein, welche das entsprechende Signal
bei vollständig zurückgezogenem Riegel 3 durch Betätigung
des Stellungssensors 6 an die Alarmzentrale 10 der Einbruchmeldeanlage

characterised in thatthe two gears (20a, 20b) of the gear pair (20a, 20b) on the motor side are fixed against rotation on a common rotary shaft and have different diameters and numbers of teeth, the motor shaft (22) of the d.c. motor (4) acting on the gear (20b) with the larger diameter while the gear (20a) with the smaller diameter reduces the rotary motor motion transmitted to the larger gear (20), transmitted further by the next gear transmission components to the gear (21) on the bolt side,in that the motor shaft (22) is partly designed as a spindle (13) or is extended through a coupling by means of a spindle and the gear with the larger diameter (20b) of the pair of gears (2) on the motor side engages in the spindle (13), andin that the pitch of the spindle (13) of the motor shaft (22) is designed to form, by the gear transmission (19) engaging the spindle (13), an irreversible mechanism which prevents forced withdrawal of the bolt (3) from its extended position. - A device for actuating a bolt according to Claim 1,
characterised in thatthe gear transmission has at least two further gear pairs (24, 25) where each of the individual gears (24a, 24b, 25a, 25b) of the gear pairs (24, 25) is fixed against rotation on a common axis and have different diameters and numbers of teeth,in that the larger gear (24b) of a first gear pair (24) can be engaged by the smaller gear (20a) of the gear pair (20) on the motor side,in that the smaller gear (25a) of a second gear pair (25) can be engaged by the gear (21) on the bolt side, andin that the smaller gear (24a) of the first gear pair (24) can be engaged by the larger gear (25b) of the second gear pair (25). - A device for actuating a bolt according to Claim 2,
characterised in that
the larger gears (24b, 25b) and each of the smaller gears (24a, 25a) of the other gear pair (24, 25) has the same diameter and the same number of teeth. - A device for actuating a bolt according to one of the preceding Claims,
characterised in that
position sensors (5, 6) are provided to identify the end positions of the bolt (3) in its fully extended or fully withdrawn positions and transmit it to the central alarm panel (10) of a burglar alarm system. - A device for actuating a bolt according to Claim 4,
characterised in that
at least one cam or nose (23) is provided on the shaft of the gear (21) on the bolt side by means of which the position sensors (5, 6) can be operated.
