Abstract
Description
Die Erfindung betrifft eine Sicherungsanordnung für Steigvorrichtungen wie Leitern, gemäß dem Oberbegriff von Anspruch 1.The invention relates to a securing arrangement for climbing devices like ladders, according to the preamble of claim 1.
Eine derartige Sicherungsanordnung für Steigvorrichtungen wie Leitern ist seit langem bekannt. Sicherungsanordnungen müssen gemäß den Vorschriften verwendet werden, wenn die betreffende Leiter eine gewisse Höhe übersteigt und kein Rückenschutz vorgesehen ist. Hierzu ist in der Regel eine Schiene mittig und parallel zu der Leiter angebracht, an der ein Sicherungsläufer schiebebeweglich gelagert ist.Such a safety arrangement for climbing devices such as Ladders have been known for a long time. Fuse arrangements must to be used in accordance with the regulations if the Ladder exceeds a certain height and no back protection is provided is. For this purpose, a rail is usually in the middle and parallel attached to the ladder on which a fuse runner is slidably mounted.
Wenn der Leiternbenutzer den Halt verliert, soll der Sicherungsläufer an speziellen und in einem Abstand von höchstens 14 cm vorgesehenen Ausnehmungen einrasten, um so einen Sturz des Leiternbenutzers, der beispielsweise über ein Tragegeschirr mit dem Sicherungsläufer verbunden ist, zu verhindern.If the ladder user loses his grip, the belay runner should on special and at a distance of at most 14 cm the provided recesses to prevent the ladder user from falling, who, for example, with a harness with the Fuse runner is connected to prevent.
Um einen Absturz sicher zu verhindern, ist es ausgesprochen wichtig, dass ein Sicherungshaken oder ein sonstiges Sicherungselement auch zuverlässig einrastet. Das Einrasten muss dann sogleich in belastbarer Weise erfolgen, denn die von dem Sicherungshaken aufzunehmende Kraft kann kurzfristig durchaus ein Mehrfaches des Gewichts des Leiterbenutzers betragen.In order to safely prevent a crash, it is pronounced important that a safety hook or other safety element also reliably engages. It must snap into place then immediately take place in a resilient manner, because that of the Force to be taken up by safety hooks can in the short term a multiple of the weight of the conductor user.
Andererseits soll der Leiterbenutzer bei der Aufwärtsbewegung möglichst wenig behindert werden. Daher haben sich Sicherungshaken bewährt, die bei der Aufwärtsbewegung zurückgezogen werden, so dass sie außer Eingriff der Fanglöcher an der Schiene sind. Aus dem vorstehend genannten Grund ist es andererseits wichtig, dass der Sicherungsläufer mit großen Kräften belastbar ist und auch mit dem erforderlichen Sicherheitsabstand präzise einrastet. Daher ist es wesentlich, dass der Sicherungshaken in jeder Richtung präzise geführt wird.On the other hand, the ladder user should move upwards be hindered as little as possible. Therefore there are safety hooks proven that are withdrawn in the upward movement so that they are out of engagement of the catch holes on the rail. On the other hand, for the reason mentioned above, it is important that the belay runner can withstand great forces and engages precisely with the required safety distance. Therefore, it is essential that the safety hook in each Direction is guided precisely.
Um zu verhindern, dass der Sicherungsläufer versehentlich fehlerhaft bedient wird, ist es auch wesentlich, dass er nicht um 180° verdreht an der Schiene angebracht wird. In diesem Falle würde er nämlich die Aufwärtsbewegung sperren und die Abwärtsbewegung gestatten. Um eine entsprechende Verdrehsicherung bereitzustellen, ist es bekannt geworden, eingangsseitig und ausgangsseitig der Schiene ein Schutzprofil anzubringen, das ein Fehleinschieben des Sicherungsläufers verhindern soll.To prevent the backup runner from accidentally failing is operated, it is also essential that he is not around Is rotated 180 ° on the rail. In this case it would block the upward movement and the downward movement allow. In order to provide an appropriate anti-rotation device, it has become known, on the input side and on the output side to attach a protective profile to the rail that prevents it from being inserted incorrectly to prevent the backup runner.
Nachteilig bei den bekannten Lösungen ist es jedoch, dass der Sicherungsläufer nicht an einer beliebigen Stelle an der Schiene angebracht werden kann, sondern nur an dem Anfang und an dem Ende sowie gegebenenfalls an speziellen Umsteigestationen.A disadvantage of the known solutions, however, is that the Fuse runner not anywhere on the rail can be attached, but only at the beginning and at the end and if necessary at special transfer stations.
Um diese Nachteile zu vermeiden, ist aus der DE-U1-298 11 906 eine Vorrichtung zum Abnehmen und Aufsetzen des Läufers einer Horizontalsicherung bekannt geworden. Es ist ein speziell ausgestaltetes Schienenstück vorgesehen, das die Entnahme des Sicherungsläufers erleichtern soll. Diese Lösung ist jedoch aufwendig herzustellen und hat den Nachteil, dass die Sicherungsfunktion an der Umsteigestelle aufgehoben ist, so dass hier besondere Vorsicht angebracht ist.To avoid these disadvantages, DE-U1-298 11 906 a device for removing and putting on the rotor one Horizontal security became known. It is a specially designed one Rail piece provided that the removal of the backup rotor should facilitate. However, this solution is complex manufacture and has the disadvantage that the security function is lifted at the transfer point, so here special Caution is appropriate.
Zudem ist ein nahtloses Gleiten des Sicherungsläufers aufgrund der beiden Schnittstellen endseitig der Umsteigestation nicht möglich.In addition, a smooth sliding of the backup rotor is due of the two interfaces at the end of the transfer station possible.
Ferner sind anstelle der zuverlässig rastenden Sicherungsläufer auch Sicherungsläufer bekannt geworden, die mit einem Exzenter arbeiten, der Reibkraft aufbringen soll. Diese Lösung ist jedoch recht umweltabhängig und bieten dann keine oder zumindest eine stark verminderte Sicherheit mehr, wenn aufgrund eines schmierigen Oberflächenbelages die Reibkraft drastisch vermindert ist. Derartige Schienen können zudem nicht gefettet werden, da ansonsten die Reibkraft zu gering wäre.Furthermore, instead of the reliably locking safety runners also known backup runners with an eccentric work that should apply friction. However, this solution is quite environmentally dependent and then offer none or at least one greatly reduced security more if due to a greasy Surface friction is drastically reduced. Such rails can also not be greased, otherwise the frictional force would be too low.
Sie sind daher dem Grunde nach schwergängiger, so dass es bereits vorgeschlagen ist, Wälzlager zu verwenden, die an dem Sicherungsläufer angebracht sind und die Beweglichkeit erhöhen soll. Derartige Wälzlager sind jedoch ihrerseits verschmutzungsanfällig und erhöhen den baulichen Aufwand, aber auch das Gewicht des Sicherungsläufers.They are therefore basically sluggish, so it already is it is proposed to use rolling bearings on the backup runner are attached and increase mobility should. However, such bearings are in turn susceptible to contamination and increase the construction effort, but also that Backup rotor weight.
Daher liegt der Erfindung die Aufgabe zu Grunde, eine Sicherungsanordnung für Steigvorrichtungen wie Leitern gemäß dem Oberbegriff von Anspruch 1 zu schaffen, die besser handhabbar ist, aber dennoch eine größere Betriebssicherheit aufweist.The invention is therefore based on the object of a fuse arrangement for climbing devices such as ladders according to the Generic preamble of claim 1 to create the more manageable is, but still has greater operational reliability.
Diese Aufgabe wird erfindungsgemäß durch Anspruch 1 gelöst. Vorteilhafte Weiterbildungen ergeben sich aus den Unteransprüchen.This object is achieved by claim 1. advantageous Further training results from the subclaims.
Die erfindungsgemäße Lösung erlaubt es erstmals, den Sicherungsläufer auch unterwegs, also über den Verlauf der Schiene an einer beliebigen Stelle einzusetzen oder auszuklinken, und zwar überraschenderweise, ohne dass die Sicherungsfunktion beeinträchtigt wird. Vielmehr erhöht sich durch diese Möglichkeit die Akzeptanz des Sicherungsläufers deutlich, so dass durch die intensivere Benutzung gewährleistet ist, dass ein erhöhtes Maß an Sicherheit für die Leiterbenutzer besteht.The solution according to the invention allows for the first time the belay runner also on the way, i.e. over the course of the rail anywhere or notch anywhere Surprisingly, without affecting the security function becomes. Rather, this option increases the Acceptance of the backup runner clearly, so that by the more intensive Use ensures that an increased level of There is security for the conductor user.
In erfindungsgemäß überraschend effizienter Weise lässt sich durch die bewegliche Lagerung der Backen des Sicherungläufers aneinander realisieren, die es erlaubt, die Backen in eine Arbeitsstellung oder in eine Lösestellung zu bringen und in diesem Zustand den Sicherungsläufer zu entnehmen oder aufzusetzen. In a surprisingly efficient manner according to the invention, due to the movable mounting of the jaws of the safety runner realizing each other, which allows the jaws to be in a working position or in a release position and in this Condition to remove or put on the fuse runner.
Erfindungsgemäß ist zusätzlich eine Verdrehsicherung vorgesehen, die ein fehlerhaftes Aufsetzen des Sicherungsläufers verhindert.According to the invention, an anti-rotation device is additionally provided, which prevents incorrect installation of the fuse runner.
Erfindungsgemäß besonders günstig ist es, wenn die Verdrehsicherung in oder an einer Backe des Sicherungsläufers realisiert ist und beispielsweise so verwirklicht ist, dass ein Schließen des Sicherungsläufers mit Sicherheit verhindert wird, wenn der Sicherungsläufer versehentlich falsch aufgesetzt wird.According to the invention, it is particularly favorable if the anti-rotation device realized in or on a jaw of the circuit breaker is and is realized, for example, so that a closing of the backup rotor is prevented with certainty if the Backup runner is accidentally placed incorrectly.
In bevorzugter Ausgestaltung ist die Verdrehsicherung als Schwerkraftsicherung ausgestaltet, die frei von der möglichen Einwirkung des Benutzers arbeitet und automatisch in der falschen Lage des Sicherungsläufers dessen Aktivierung blockiert.In a preferred embodiment, the anti-rotation device is as Gravity control designed to be free from the possible User action works and automatically in the wrong one Position of the backup runner whose activation is blocked.
Erfindungsgemäß bevorzugt ist es bei dieser Ausführungsform, dass zusätzlich eine Verdrehsicherung durch ein an sich bekanntes Profilelement realisiert ist, das das Einführen an dem Eingang oder dem Ausgang oder gegebenenfalls einer Umsteigestation der Schiene dann verhindert, wenn der Sicherungsläufer die falsche Lage einnimmt.According to the invention, it is preferred in this embodiment that additionally an anti-rotation device by a known Profile element is realized, the insertion at the entrance or the exit or, if necessary, a transfer station the rail is prevented if the belay runner is the wrong one Takes position.
Erfindungsgemäß ist es besonders günstig, dass die zusätzliche Verdrehsicherung in mechanisch einfacher Weise ausgebildet sein kann. So kann beispielsweise ein abgerundeter Vorsprung an einer der Backen vorgesehen sein, der mit einer einseitig vorgesehenen Sperre an der Schiene zusammenarbeitet und bei richtiger Ausrichtung des Sicherungsläufers das Einschieben erlaubt, bei verdrehter Position dies jedoch verhindert.According to the invention, it is particularly favorable that the additional Protection against rotation in a mechanically simple manner can. For example, a rounded projection on one the jaws should be provided with a one-sided Lock works together on the rail and with correct alignment of the fuse runner allows insertion, when twisted Position prevented this however.
Besonders günstig ist es auch, dass alle sicherungsrelevanten Teile, wie die Federn für die Backen, aber auch die integrierte Verdrehsicherung, gekapselt untergebracht und damit vor Verschmutzung geschützt sind.It is also particularly favorable that all security-relevant Parts like the springs for the cheeks, but also the integrated ones Anti-twist protection, encapsulated and thus against contamination are protected.
Damit ist der erfindungsgemäße Sicherungsläufer auch in stark verschmutzungsanfälligen Umgebungen geeignet und insbesondere auch unabhängig vom Verschmutzungszustand der Schiene, so dass erhöhten Sicherungsanforderungen Rechnung getragen werden kann.Thus, the backup runner according to the invention is also strong suitable for pollution-prone environments and in particular also regardless of the contamination status of the rail, so that increased security requirements can be taken into account.
