Abstract

Diese Erfindung betrifft einen Schwenkantrieb u. a. für zweiteilige, faltbare Boden- und Galerietreppen, der sowohl einen max. Schwenkwinkel von über 180° als auch ein großes, relativ gleichmäßiges, u. a. für den Motorantrieb von Treppen geeignetes Drehmoment bietet. Als Antriebselement kann ein handelsüblicher Linearmotor verwendet werden. Das Getriebe dieses Schwenkantriebs besteht aus zwei einfachen, parallel angeordneten, ebenen Viergelenkgetrieben, die neben einer kostengünstigen Herstellung auch sehr zuverlässig und praktisch verschleiß- und wartungsfrei sind. Wie handelsübliche Schwenkantrieb wird der angetriebene Bauteil seitlich direkt an diesem Schwenkantrieb angeschlossen. Je nach dem Bedarf kann dieser Schwenkantrieb sowohl in offener Form als auch in geschlossener Form ausgeführt werden.

This invention relates to a rotary actuator, inter alia, for two-piece, foldable floor and gallery stairs, both a max. Swing angle of over 180 ° and a large, relatively uniform, including suitable for the motor drive of stairs torque offers. As a driving element, a commercially available linear motor can be used. The transmission of this rotary actuator consists of two simple, parallel, flat four-bar linkages, which are not only cost-effective production but also very reliable and practically wear and maintenance-free. As commercial rotary actuator, the driven component is connected laterally directly to this rotary actuator. Depending on the needs of this rotary actuator can be performed both in an open form and in a closed form.
