Abstract

A load lowering or rescue device for lowering a load or person from an elevated location, has a drum rotatably mounted on a frame. One end of a rope or cable is secured at the elevated location. The other end of the rope or cable is secured to the drum and a portion of the rope or cable is wound around the drum. A spring biased drum brake cooperates with the drum for controlling the lowering speed or for stopping the drum rotation. First and second brake action control members permit controlling the brake action in opposite directions, for example, one control member permits reducing the brake force for accelerating the lowering speed, while the other control member permits selectively increasing the brake force and stopping the lowering. The control members cooperate with a rocker brake lever, and at least one control member cooperates with a lever linkage system connected to the rocker brake lever and to a, preferably spring biased, load attachment device in such a manner that the load being lowered automatically adjusts a spring bias for a constant lowering speed, when the control members are not operated.

Description

Die Erfindung betrifft ein Personen-Abseilgerät, bestehend aus einem Seil, dessen eines Ende Befestigungsmittel zur ortsfesten Festlegung an einem Gebäudeteil aufweist und dessen anderes Ende an einer Seiltrommel befestigt ist, die in einem Rahmen drehbar gelagert ist, der Rahmen Anschlusseinrichtungen für eine Personentragvorrichtung aufweist, die Seiltrommel mit einer zur Regelung der Abseilgeschwindigkeit dienenden, unter Federvorspannung stehenden Bremse in Wirkverbindung steht, wobei die Bremse über einen als Wippe ausgebildeten Bremshebel während des Abseilens betätigbar ist und der Bremshebel einerseits zum manuellen Lösen der Bremse über ein erstes Betätigungsorgan entgegen der Vorspannfederkraft und andererseits zur manuellen Erhöhung der Bremskraft über ein zweites Betätigungsorgan beeinflussbar ist.The invention relates to a person descender device, consisting of a rope, one end of which has fastening means for fixed attachment to a part of the building and the other end of which is attached to a rope drum which is rotatably mounted in a frame, the frame has connection devices for a person carrying device, the cable drum is operatively connected to a brake which serves to regulate the abseiling speed and is under spring preload, the brake being operable during abseiling via a brake lever designed as a rocker and the brake lever on the one hand for manually releasing the brake via a first actuating element against the prestressing spring force and on the other hand for manually increasing the braking force can be influenced by a second actuator.

Ein Personen-Abseilgerät dieser Art, von dem die Erfindung ausgeht, ist aus der DE-B-2 646 368 bekannt.A personal descender of this type, from which the invention is based, is known from DE-B-2 646 368.

Dieses bekannte Abseilgerät gewährleistet zwar eine konstante Abseilgeschwindigkeit, ohne dazu die auf die Seiltrommel wirksame Bremse betätigen zu müssen, jedoch nur dann, wenn zuvor die auf die Seiltrommel wirkende Bremse auf das Körpergewicht der abzuseilenden Person eingestellt worden ist.This known abseiling device ensures a constant abseiling speed without having to actuate the brake acting on the cable drum, but only if the brake acting on the cable drum has previously been adjusted to the body weight of the person to be abseiled.

Aus der DE-A-2 903 403 ist ein Personenabseilgerät bekannt, bei welchem die auf die Seiltrommel wirkende Bremskraft von Hand mittels einer Handkurbel auf das Gewicht der abzuseilenden Person eingestellt werden kann.From DE-A-2 903 403 a person descender is known in which the braking force acting on the cable drum can be adjusted by hand to the weight of the person to be abseiled using a hand crank.

Aufgabe der Erfindung ist es nun, ein Personen-Abseilgerät der im Oberbegriff des Anspruchs 1 angegebenen Art unter Beibehaltung der beim Stand der Technik bereits erreichten Vorteile, die darin bestehen, dass die Abseilgeschwindigkeit durch die abzuseilende Person während des Abseilens bei Bedarf sowohl bis zum Stillstand verzögert als auch erhöht werden kann, derart zu verbessern, dass mit einfachen Mitteln und Massnahmen ansonsten eine konstante Abseilgeschwindigkeit erreichbar ist, ohne die Bremse zuvor auf das jeweilige Körpergewicht der abzuseilenden Person einstellen zu müssen.The object of the invention is now to provide a personal rappelling device of the type specified in the preamble of claim 1 while maintaining the advantages already achieved in the prior art, which consist in the fact that the rappelling speed by the person to be rappelled during rappelling, if necessary, both to a standstill can be delayed as well as increased in such a way that simple means and measures can otherwise achieve a constant abseiling speed without having to adjust the brake beforehand to the respective body weight of the person to be abseiled.

Diese Aufgabe wird bei einem Personen-Abseilgerät der eingangs genannten Art erfindungsgemäss nach dem Kennzeichen des Anspruchs 1 gelöst.This object is achieved according to the invention in accordance with the characterizing part of claim 1 in a personal rappelling device of the type mentioned at the outset.

Durch die Massnahmen wird nunmehr bei Belastung der Personentragvorrichtung die abzuseilende Person quasi gewogen und anschliessend daran die auf die Seiltrommel wirksame Bremse entsprechend dem jeweiligen Körpergewicht der abzuseilenden Person selbsttätig so eingestellt, dass nunmehr unabhängig vom Körpergewicht der abzuseilenden Person eine konstante Abseilgeschwindigkeit sichergestellt ist. Dabei ist die Feder als Druckfeder ausgebildet, um auch bei einem Bruch der Feder konstante Abseilgeschwindigkeit zu erreichen.As a result of the measures, the person to be rappelled is now weighed when the person carrying device is loaded and then the brake acting on the cable drum is automatically adjusted in accordance with the body weight of the person to be descended so that a constant rappelling speed is now ensured regardless of the body weight of the person to be descended. The spring is designed as a compression spring in order to achieve a constant abseiling speed even if the spring breaks.

Um den Verstellweg der von der abzuseilenden Person belasteten Feder an den Verstellweg des Bremshebels anpassen zu können, ist es vorteilhaft, wenn das vorgenannte Zugorgan über einen am Rahmen schwenkbar angelenkten Hebel mit dem Bremshebel verbunden ist.In order to be able to adapt the adjustment path of the spring loaded by the person to be abseiled to the adjustment path of the brake lever, it is advantageous if the aforementioned traction element is connected to the brake lever via a lever pivotably articulated on the frame.

Eine vorteilhafte Weiterbildung der vorbeschriebenen Vorrichtung, welche es mit einfachen Mitteln und Massnahmen ermöglicht, die Bremse wahlweise auch manuell lösen zu können, ist im Anspruch 4 offenbart. Ausserdem kann eine Vereinfachung der Erfindung in dem Sinne durchgeführt werden, dass von der sich selbsttätig dem jeweiligen Körpergewicht der abzuseilenden Person entsprechend einstellenden konstanten Abseilgeschwindigkeit ausgehend, von der betreffenden Person über das eine Betätigungsorgan zwar eine stufenlose Erhöhung der Abseilgeschwindigkeit einstellbar ist, dass aber über das andere Betätigungsorgan statt einer stufenlos erhöhbaren Bremswirkung nur ein vollständiges Anhalten möglich ist. Vom Haltezustand aus ist dann wieder z.B. nach Lösen einer Arretierung ein weiteres Abseilen mit der vorgegebenen konstanten Abseilgeschwindigkeit durchführbar.An advantageous further development of the device described above, which makes it possible with simple means and measures to optionally also release the brake manually, is disclosed in claim 4. In addition, a simplification of the invention can be carried out in the sense that, starting from the constant abseiling speed that automatically adjusts itself to the respective body weight of the person to be abseiled, a continuous increase in the abseiling speed can be set by the person in question via the one actuating element, but via the other actuator only a complete stop is possible instead of a continuously increasing braking effect. From the stop state, e.g. after releasing a locking device, another rappelling can be carried out at the specified constant rappelling speed.

Ein Ausführungsbeispiel der Erfindung ist in den Zeichnungen dargestellt und wird im folgenden näher beschrieben.An embodiment of the invention is shown in the drawings and will be described in more detail below.

Es zeigt:

  • Fig.1 wesentliche Teile einer Personen-Abseilvorrichtung in der Vorderansicht, teilweise aufgebrochen,
  • Fig.2 desgleichen in der Seitenansicht, ebenfalls teilweise aufgebrochen.
It shows:
  • 1 essential parts of a person rappelling device in front view, partially broken away,
  • Fig.2 same in side view, also partially broken.

Bei dieser Personen-Abseilvorrichtung ist an einem ringförmig geschlossenen Rahmen 1 eine Seiltrommel 2 um eine rahmenfeste Achse 3 drehbar gelagert. Zur Bildung einer Backenbremse 4 ist die Seiltrommel 2 auf ihrer Stirnseite mit einer zylindrischen Ausnehmung 22 versehen, in der auf bekannte Weise zwei auf deren zylindrische Außenseite wirkende Bremsbacken angeordnet sind. Die beiden Bremsbacken sind dabei um die Drehpunkte 23 und 24 schwenkbar mit einem fest mit dem Rahmen 1 verbundenen Tragteil 25 verbunden. Auf der diametral gegenüberliegenden Seite der beiden Drehpunkte 23 und 24 ist der Tragteil 25 mit einem Ansatz 26 versehen, in welchem eine starr mit dem Bremshebel 5 verbundene Bremsbackenbetätigungswelle drehbar gelagert ist. Die letztere ist auf ihrer aus dem Ansatz 26 herausragenden, zwischen den beiden freien Enden der Bremsbacken sich befindenden Seite abgeflacht ausgebildet, sodaß bei einer Schwenkung des Bremshebels 5 eine entsprechende Betätigung der über ihre freien Enden an diesem als Bremsbackenspreizteil wirkenden abgeflachten Teil der Betätigungswelle 5 anliegenden Bremsbacken bewirkt wird.In this person rappelling device, a cable drum 2 is rotatably mounted about a frame-fixed axis 3 on an annularly closed frame 1. To form a shoe brake 4, the cable drum 2 is provided on its end face with a cylindrical recess 22 in which two brake shoes acting on the cylindrical outside thereof are arranged in a known manner. The two brake shoes are pivotally connected about the pivot points 23 and 24 to a supporting part 25 which is fixedly connected to the frame 1. On the diametrically opposite side of the two pivot points 23 and 24, the support part 25 is provided with a shoulder 26 in which a brake shoe actuation shaft rigidly connected to the brake lever 5 is rotatably mounted. The latter is flattened on its side protruding from the extension 26, located between the two free ends of the brake shoes, so that when the brake lever 5 is pivoted, a corresponding actuation of the flattened part of the actuating shaft 5, which acts via its free ends, as a brake shoe spreading part Brake shoes is effected.

An dem einen Hebelarm 6 des Bremshebels 5 greift eine am Rahmen 1 gehaltene und in ihrer Federkraft einstellbare Zugfeder 7 an. Am anderen Hebelarm 8 greift mittelbar ein Zugorgan 9 in Form eines Stahlseiles an, mit welchem die Bremse 4 gegen die Federkraft der Zugfeder 7 manuell gelöst werden kann. Der Hebelarm 8 des Bremshebels 5 ist noch mit einem zweiten Zugorgan 10 in Form eines manuell betätigbaren Bowdenzuges verbunden, mit welchem die Bremskraft der Backenbremse 4 bis zum Stillstand der Seiltrommel 2 manuell abgebremst werden kann, wozu der Bremshebel 5 im Uhrzeigersinn verschwenkt wird.On the one lever arm 6 of the brake lever 5, a tension spring 7 held on the frame 1 and adjustable in its spring force engages. At the other lever arm 8 indirectly engages a tension member 9 in the form of a steel cable with which the brake 4 can be released manually against the spring force of the tension spring 7. The lever arm 8 of the brake lever 5 is also connected to a second pulling element 10 in the form of a manually operable Bowden cable, with which the braking force of the shoe brake 4 can be braked manually to a standstill of the cable drum 2, for which purpose the brake lever 5 is pivoted clockwise.

Das an der Seiltrommel 2 mit dem einen Ende festgelegte Drahtseil 11 ist in an sich bekannter Weise durch den oberen Endteil des Rahmens 1 hindurchgeführt, und hat an seinem freien Ende, z.B. einen Karabinerhaken, zum Festlegen des freien Seilendes ein einem geeigneten Gebäudeteil. Am unteren Ende des Rahmens 1 ist eine nicht dargestellte Personentragvorrichtung befestigt. Ferner ist die Abseilvorrichtung von einem Gehäuse 12 umgeben.The wire rope 11 fixed to the rope drum 2 with one end is guided in a known manner through the upper end part of the frame 1, and has at its free end, e.g. a snap hook, for fixing the free end of the rope to a suitable part of the building. At the lower end of the frame 1, a person carrying device, not shown, is attached. Furthermore, the abseiling device is surrounded by a housing 12.

Am unteren Rahmenschenkel des Rahmens 1 ist eine Hülse 13 befestigt, in die eine als Schraubendruckfeder ausgebildete Feder 14 so eingesetzt ist, daß deren Wirkrichtung lotrecht verläuft. Der untere Endteil der Feder stützt sich am Boden der Hülse 13 ab. Durch die Feder 14 greift ein als Kopfbolzen ausgebildetes Zugorgan 15, dessen Kopf sich mittelbar am oberen Endteil der Feder 14 abstützt. An dem die Hülse 13 nach unten durchgreifenden Schaft des Zugorganes 15 ist eine Öse 16 zum Anschluß der Personentragvorrichtung angeschraubt. Durch mehr oder weniger weites Aufschrauben der Öse 16 auf den Schaft des Zugorganes 15 kann die Federvorspannung der Feder 14 verändert werden.On the lower frame leg of the frame 1, a sleeve 13 is fastened, in which a spring 14 designed as a helical compression spring is inserted so that its direction of action is perpendicular. The lower end part of the spring is supported on the bottom of the sleeve 13. Through the spring 14, a pulling element 15 designed as a head pin engages, the head of which is supported indirectly on the upper end part of the spring 14. On the shaft 13 of the traction member 15 reaching downward, an eyelet 16 is screwed for connecting the person carrying device. By more or less screwing the eyelet 16 onto the shaft of the tension member 15, the spring preload of the spring 14 can be changed.

Der Kopf des Zugorganes 15 ist vom Boden eines Gabelstückes 16' unterfaßt, an welchem ein einarmiger Hebel 17 angelenkt ist, dessen Drehpunkt 18 am Lastarm eines zweiten, zweiarmigen und am Rahmen 1 schwenkbar gelagerten Hebels 19 angelenkt ist. Der Kraftarm des Hebels 19 ist mit dem Zugorgan 9 verbunden. Außerdem ist der Lastarm des Hebels 17 über ein längenveränderbares Kupplungsstück 20 mit dem Hebelarm 8 des Bremshebels 5 gelenkig verbunden. Zudem ist eine rahmenfest gehalterte und auf das Zugorgan 9 wirksame Rückstellfeder 21 vorgesehen.The head of the traction element 15 is gripped from the bottom of a fork piece 16 ', to which a one-armed lever 17 is articulated, the fulcrum 18 of which is articulated on the load arm of a second, two-armed lever 19 which is pivotably mounted on the frame 1. The power arm of the lever 19 is connected to the tension member 9. In addition, the load arm of the lever 17 is articulated to the lever arm 8 of the brake lever 5 via a variable-length coupling piece 20. In addition, a return spring 21 is provided which is fixed to the frame and is effective on the tension member 9.

Alle neuen, in der Beschreibung und/oder Zeichnung offenbarten Einzel- und Kombinationsmerkmale werden als erfindungswesentlich angesehen.All new individual and combination features disclosed in the description and / or drawing are regarded as essential to the invention.
