Claims (8)

1. Beschattungsvorrichtung, insbesondere Markise, Rolladen oder Jalousie, mit einer drehbar gelagerten Welle (11), einem flächigem Beschattungselement, das wahlweise einziehbar und auf der Welle (11) aufroll­ bar oder ausfahrbar und flächig aufspannbar ist, und einem in entgegengesetzte Richtungen in Drehung versetzbaren Antriebsteil (14), dessen Drehbewegung über ein Getriebe auf die Welle (11) übertragbar ist, dadurch gekennnzeichnet, daß zwischen dem Antriebsteil (14) und dem Getriebe eine Kupplung (13) angeordnet ist, mittels der in die entgegenge­ setzten Drehrichtungen unterschiedliche Drehmomente übertragbar sind, wobei das in Einziehrichtung des Beschattungselementes übertragbare Drehmoment größer als das in Ausfahrrichtung des Beschattungselementes übertragbare Drehmoment ist.1. Shading device, in particular awning, roller shutters or blinds, with a rotatably mounted shaft ( 11 ), a flat shading element that can be optionally retracted and rolled up on the shaft ( 11 ) or extendable and stretched flat, and one in opposite directions in rotation displaceable drive part ( 14 ), the rotational movement of which can be transmitted to the shaft ( 11 ) via a gear, characterized in that a clutch ( 13 ) is arranged between the drive part ( 14 ) and the gear, by means of the different torques in the opposite directions of rotation are transferable, the torque that can be transmitted in the pulling-in direction of the shading element being greater than the torque that can be transmitted in the extending direction of the shading element. 2. Beschattungsvorrichtung nach Anspruch 1, dadurch gekennzeichnet, daß die Kupplung (13) eine Reibkupp­ lung ist. 2. Shading device according to claim 1, characterized in that the coupling ( 13 ) is a Reibkupp treatment. 3. Beschattungsvorrichtung nach Anspruch 1 oder 2, dadurch gekennzeichnet, daß die Kupplung ein Klemm­ teil (16) aufweist, das in Abhängigkeit von der Drehrichtung mit unterschiedlicher Vorspannung an einer Klemmfläche (15b) anliegt.3. Shading device according to claim 1 or 2, characterized in that the coupling has a clamping part ( 16 ) which, depending on the direction of rotation with different bias on a clamping surface ( 15 b). 4. Beschattungsvorrichtung nach Anspruch 3, dadurch gekennzeichnet, daß das Klemmteil eine Spiralfeder (16) ist, die in Abhängigkeit von der Drehrichtung radial nach außen aufweisbar oder radial nach innen einziehbar ist.4. Shading device according to claim 3, characterized in that the clamping part is a spiral spring ( 16 ) which, depending on the direction of rotation, is radially outward or retractable radially inward. 5. Beschattungsvorrichtung nach Anspruch 4, dadurch gekennzeichnet, daß die Spiralfeder (16) auf der Außenseite eines zylindrischen Mitnehmers (18) angeordnet ist, der ihre radial nach innen gerichte­ te Bewegung begrenzt.5. Shading device according to claim 4, characterized in that the coil spring ( 16 ) on the outside of a cylindrical driver ( 18 ) is arranged, which limits its radially inward movement te. 6. Beschattungsvorrichtung nach Anspruch 5, dadurch gekennzeichnet, daß die Spiralfeder (16) mit ihrem einen Ende (16a) im wesentlichen spielfrei in einer Nut (18d) des Mitnehmers (18) sitzt.6. Shading device according to claim 5, characterized in that the coil spring ( 16 ) with its one end ( 16 a) sits essentially free of play in a groove ( 18 d) of the driver ( 18 ). 7. Beschattungsvorrichtung nach einem der Ansprüche 3 bis 6, dadurch gekennzeichnet, daß die Klemmfläche (15b) an einer die Spiralfeder (16) umgebenden rohrförmigen Buchse (15) ausgebildet ist.7. Shading device according to one of claims 3 to 6, characterized in that the clamping surface ( 15 b) on a the spiral spring ( 16 ) surrounding tubular socket ( 15 ) is formed. 8. Beschattungsvorrichtung nach einem der Ansprüche 1 bis 7, dadurch gekennzeichnet, daß das Getriebe einen Endanschlag für die vollständig ausgefahrene Stellung des Beschattungselementes aufweist und daß die vom Endanschlag aufnehmbare Kraft größer als die Kraft ist, die aus dem in Ausfahrrichtung des Be­ schattungselementes übertragbaren Drehmoment resul­ tiert.8. Shading device according to one of claims 1 to 7, characterized in that the gear a stop for the fully extended Has position of the shading element and that the force that can be absorbed by the end stop is greater than that Force is from the in the extension direction of the loading transferable torque element resul animals.
