Abstract

Die vorliegende Erfindung umfasst ein Abseilgerät mit einer Windenvorrichtung, einer drehbar gelagerten Hauptachse (12), auf der drehfest eine Seilscheibe (14) zum schlupfsicheren Führen eines Zugmittels angeordnet ist, und einer mit der Seilscheibe (14) kraftübertragend verbundenen Abseilvorrichtung (16), welche zum Halten einer konstanten Abseilgeschwindigkeit einer an dem Zugmittel hängenden Last ausgebildet ist, wobei die Windenvorrichtung eine Betätigungseinrichtung aufweist, die über einen Kraftübertragungsweg mit der Seilscheibe (14) zum manuellen Drehen der Seilscheibe (14) verbunden ist. Hierbei ist in einem Kraftübertragungsweg zwischen dem Betätigungselement der Windenvorrichtung und der Seilscheibe (14) mindestens eine Knarrenvorrichtungen (24) angeordnet, wobei die Knarrenvorrichtung (24) mindestens zwischen einem ersten Zustand und einem dritten Zustand umschaltbar ist, wobei in dem ersten Zustand der Knarrenvorrichtung (24) in eine erste Drehrichtung (38) der Betätigungseinrichtung diese über die jeweilige Knarrenvorrichtung (24) kraftübertragend mit der Seilscheibe (14) verbunden ist und in eine entgegengesetzte zweite Drehrichtung (36) der Betätigungseinrichtung diese frei relativ zur Seilscheibe (14) drehbar ist, wobei in dem dritten Zustand der jeweiligen Knarrenvorrichtung (24) in die erste und zweite Drehrichtung (38, 36) der Betätigungseinrichtung diese frei relativ zur Seilscheibe (14) drehbar ist, wobei die Betätigungseinrichtung mindestens einen Hebelarm (28) aufweist, welcher derart angeordnet ist, dass dieser Hebelarm (28) über die Knarrenvorrichtung (24) Drehkräfte in den Kraftübertragungsweg zwischen der Seilscheibe (14) und der Betätigungseinrichtung einleitet.

Figure imgaf001
The present invention comprises a descender with a winch device, a rotatably mounted main axis (12) on which a pulley (14) for non-slip guiding a traction means is rotatably mounted, and a with the pulley (14) force transmitting connected abseiling device (16) which is designed to maintain a constant abseiling speed of a load suspended on the traction means, wherein the winch device comprises an actuating device which is connected via a power transmission path with the sheave (14) for manually rotating the sheave (14). Here, in a power transmission path between the actuating element of the winch device and the pulley (14) at least one ratchet devices (24) is arranged, wherein the ratchet device (24) is switchable at least between a first state and a third state, wherein in the first state of the ratchet device ( 24) in a first direction of rotation (38) of the actuating device via the respective ratchet device (24) is force-transmitting connected to the sheave (14) and in an opposite second direction of rotation (36) of the actuating device that is freely rotatable relative to the sheave (14), wherein in the third state of the respective ratchet device (24) in the first and second rotational direction (38, 36) of the actuator that is freely rotatable relative to the sheave (14), wherein the actuating means comprises at least one lever arm (28) which is arranged in that this lever arm (28) protrudes beyond the ratchet Direction (24) initiates rotational forces in the power transmission path between the pulley (14) and the actuator.
