Die Abdeckbahn ist z.B. ein Vorhangstoff oder ein Markisenstoff oder ist von Lamellen gebildet oder als Rolladen gestaltet. Die abgewickelte Abdeckbahn ist vertikal oder schräg angeordnet und wird zum Auffahren von unten nach oben oder von oben nach unten bewegt. Die Wickelwelle läßt sich vertikal anordnen, wobei sich die Abdeckbahn horizontal bewegt. Der Wickelmotor ist z.B. ein Rohrmotor oder ein Rechteckmotor. Es ist auch möglich, das drehbare Wickelstück mit horizontaler Achse anzuordnen und einer Abdeckung zuzuordnen, die sich im Abdeckzustand in einer horizontalen Ebene erstreckt.The cover sheet is e.g. a curtain fabric or an awning fabric or is formed by slats or designed as roller shutters. The settled Cover sheet is arranged vertically or at an angle and is used to drive up from bottom to top or from top to bottom emotional. The winding shaft can be arranged vertically, whereby the cover sheet moves horizontally. The winding motor is e.g. a tubular motor or a rectangular motor. It is also possible that Arrange rotatable winding piece with a horizontal axis and one Assign cover that is in the cover state in a extends horizontal plane.

Besonders zweckmäßig und vorteilhaft ist es, wenn die Riegeleinrichtung ein axial verschiebbares Riegelteil aufweist, das eine Entriegelfeder im gespannten Zustand hält und das mittels eines Widerlagers abgestützt ist, das als Betätigungselement verschiebbar ist. Durch ein kurzes Verschieben des Widerlager-Betätigungselements wird die zunächst gespannte Entriegelfeder wirksam, welche die Entriegelung durchführt, wodurch die Federwelle wirksam wird.It is particularly expedient and advantageous if the locking device has an axially displaceable locking part which has an unlocking spring holds in the tensioned state and that by means of an abutment is supported, which is displaceable as an actuating element. By moving the abutment actuator briefly the initially tensioned release spring is effective, which the Unlocking is carried out, whereby the spring shaft is effective.

Besonders zweckmäßig und vorteilhaft ist es auch, wenn der Wickelmotor bzgl. des Wickelstücks axial verschiebbar angeordnet ist, einerseits an der Riegeleinrichtung angreift und andererseits an dem Befestigungselement angreift. Es ist der Wickelmotor Bestandteil eines Verbindungssystems zwischen der Riegeleinrichtung und dem Betätigungselement.It is also particularly expedient and advantageous if the winding motor is axially displaceable with respect to the winding piece, attacks on the locking device on the one hand and on the other Fastener attacks. It is part of the winding motor a connection system between the locking device and the Actuator.

Besonders zweckmäßig und vorteilhaft ist es ebenso, wenn der Wickelmotor mit einem von dem Wickelstück herausragenden Motorzapfen an dem ortsfesten Lager undrehbar und axial verschiebbar ist. Dies vereinfacht die axiale Bewegbarkeit des Wickelmotors, der das Wickelstück nicht mehr trägt, also jetzt auf der Federwelle sitzt.It is also particularly expedient and advantageous if the Winding motor with a motor pin protruding from the winding piece non-rotatable and axially displaceable on the fixed bearing is. This simplifies the axial mobility of the winding motor, who no longer carries the winding piece, so now on the spring shaft sits.

Besonders zweckmäßig und vorteilhaft ist es weiterhin, wenn das Abtriebsteil des Wickelmotors an einem Riegelteil der Riegeleinrichtung starr befestigt ist. Dies gibt dem Riegelteil die zusätzliche Funktion der Verbindung der Riegeleinrichtung mit dem Abtriebsteil des Wickelmotors.It is also particularly expedient and advantageous if that Output part of the winding motor on a locking part of the locking device is rigidly attached. This gives the latch part the extra Function of the connection of the locking device with the driven part of the winding motor.

Besonders zweckmäßig und vorteilhaft ist es sodann, wenn die Riegeleinrichtung einerseits ein als Stift ausgebildetes Riegelteil und andererseits ein an dem Stift verschiebbares Schiebestück als Riegelteil bildet. Dies vereinfacht die Bauweise. It is then particularly expedient and advantageous if the locking device on the one hand a locking part designed as a pin and on the other hand a sliding piece on the pin as a locking part forms. This simplifies the construction.
