Die Vorrichtung weist eine Führungsschiene zur Führung einer Fangeinrichtung, an der eine den Steigweg gehende Person gesichert werden kann, und ein Verlängerungsstück der Führungsschiene am oberen Ende der Führungsschiene auf.The invention relates to a device according to the preamble of claim 1 for secure leaving and entering a Steigweg when transitioning to a stage, the roof of one Structure, a pedestal or when leaving and boarding one Shaft. The device has a guide rail Guidance of a safety gear on which one of the ascending path Person can be secured, and an extension piece the guide rail at the upper end of the guide rail.

Die Unfallverhütungsvorschriften schreiben vor, daß bei Leiterenden an Dachkanten, Dachaufstiegen oder Schächten ein Überstand der Leiter von 1 m vorhanden sein muß. Eine Leiter mit einem solchen Überstand ist aus DE-U-88 09 386 bekannt. Der Überstand oder die Verlängerung ist dabei verschwenkbar um eine vertikale Achse am oberen Ende der Leiter angeordnet. Für Dachluken oder Schachtabdeckungen ist diese Vorrichtung nicht geeignet, da hier die Schachtabdeckung bzw. das Dachfenster mit dem Überstand kollidieren würde. Bei Schachtabdeckungen und Dachluken wurde der Überstand bisher getrennt aufbewahrt und beim Einsatz auf das obere Ende der Leiter aufgesteckt; eine derartige Vorrichtung geht aus einem Prospekt der Fa. HACA "Fallschutzsysteme, Sicherheitsgeschirre, Steigeisen" (siehe Seite 27, "Aufsteckbare bzw. umklappbare Einsteighilfen") als nächstliegenden Stand der Technik hervor.The accident prevention regulations stipulate that at Conductor ends at roof edges, roof stairs or shafts The conductor must protrude by 1 m. A ladder with such a supernatant is known from DE-U-88 09 386. The protrusion or the extension is pivotable about a vertical axis is located at the top of the ladder. For This device is not roof hatches or manhole covers suitable, since here the shaft cover or the roof window would collide with the supernatant. For manhole covers and the roof hatches, the supernatant was previously kept separately and attached to the top of the ladder when in use; such a device is based on a brochure from HACA "Fall Protection Systems, Safety Harnesses, Crampons" (see page 27, "Clip-on or fold-down entry aids") as the closest prior art.

Zur Herstellung einer Verbindung mit dem oberen Ende der Führungsschiene ist das Verlängerungsstück um eine vertikale Achse schwenkbar ausgebildet. Für den Einsatz wird das Verlängerungsstück dann zunächst bis zu einem Anschlag nach oben gezogen oder geschoben und dann um 180° um die vertikale Achse gedreht und auf das Ende der festmontierten Führungsschiene aufgesetzt.To connect to the top of the The guide rail is the extension piece by a vertical Swivel axis. For use it will Extension piece then first up to a stop pulled or pushed at the top and then 180 ° around the vertical Axis rotated and on the end of the fixed guide rail placed.

Mittels Zentrierungslaschen am oberen Ende der festangeordneten Führungsschiene kann eine Fehlfluchtung zwischen Verlängerungsstück und Führungsschiene verhindert und ein sicheres Durchfahren der Verbindungsstelle mit einer Fangeinrichtung gewährleistet werden. Besonders platzsparend ist die Anordnung, wenn das Verlängerungsstück hinter der Führungsschiene vertikal verschiebbar gelagert ist.Using centering tabs at the top of the fixed Guide rail can misalign between Extension piece and guide rail prevented and on safe passage through the connection point with a safety gear be guaranteed. It is particularly space-saving Arrangement when the extension piece is behind the guide rail is vertically slidably mounted.

Um das Verlängerungsstück in die erste Position oder Ruheposition zu bringen, wird das Verlängerungsstück angehoben, um 180° verschwenkt und dann heruntergelassen oder versenkt. In der ersten Position ist das Verlängerungsstück äußerst platzsparend hinter der Führungsschiene, d.h. im allgemeinen zwischen der Führungsschiene und dem Mauerwerk, an dem die Führungsschiene befestigt ist, verstaut.To the extension piece in the first position or rest position to bring the extension piece is raised to Swiveled 180 ° and then lowered or sunk. In In the first position, the extension piece is extremely space-saving behind the guide rail, i.e. generally between the guide rail and the masonry on which the guide rail attached, stowed.

Vorzugsweise ist das Verlängerungsstück an einem Rohr befestigt, das durch zwei Paare von Führungsrollen vertikal verschiebbar und um seine Längsachse verdrehbar angeordnet ist. The extension piece is preferably attached to a tube, that can be moved vertically by two pairs of guide rollers and is arranged rotatable about its longitudinal axis.

Die beiden Paare von Führungsrollen sind vorzugsweise am oberen Ende der festangeordneten Führungsschiene gelagert.The two pairs of guide roles are preferably on the upper end of the fixed guide rail.

Die erfindungsgemäße Vorrichtung eignet sich insbesondere zum Einsatz bei Einholm- oder Mittelholmleitern mit Absturzsicherung, wie sie aus DE-A-19 61 757 bekannt ist.

Bei dem in der Zeichnung dargestellten Ausführungsbeispiel ist eine Führungsschiene 10 mittels Bügel 12 an einem Bauwerk B, z.B. der Innenwand eines Schachtes, festgedübelt. In regelmäßigen Abständen sind auf der Rückseite der Führungsschiene 10 Tritte 14 befestigt. Die Führungsschiene 10 bildet zusammen mit den Tritten 14 eine Einholm- oder Mittelholmleiter.In the embodiment shown in the drawing a guide rail 10 by means of brackets 12 on a building B, e.g. the inner wall of a shaft, dowelled. In regular Clearances are on the back of the guide rail 10 steps 14 attached. The guide rail 10 forms together with the steps 14 a single-beam or central beam ladder.

Zugleich dient die Führungsschiene 10 zur Führung einer in der Zeichnung nicht dargestellten Fangeinrichtung, die zusammen mit der Führungsschiene 10 Teil einer Absturzsicherung ist, wie sie aus DE-A-19 61 757, DE-A-27 36 037 und EP-A-0 168 021 bekannt ist. At the same time, the guide rail 10 serves to guide one in the Drawing, not shown, safety gear together with the guide rail 10 is part of a fall protection device, as described in DE-A-19 61 757, DE-A-27 36 037 and EP-A-0 168 021 is known.

In dem Raum zwischen der Führungsschiene 10 und dem Bauwerk B ist unmittelbar hinter der Führungsschiene 10 ein Rohr 16 durch zwei Paare von Führungsrollen 18 gelagert, so daß das Rohr 16 parallel zur Führungsschiene 10 verschiebbar ist, d.h. nach oben herausziehbar und nach unten versenkbar ist. Jedes Paar von Führungsrollen 18 ist dazu auf einer Trägerplatte 20 montiert, die auf der Rückseite der Führungsschiene 10 befestigt ist. Die Führungsrollen 18 sitzen auf Achsstummeln 22, die senkrecht zur Führungsschiene 10 und den Tritten 14 stehen. Der Abstand der Führungsrollen 18 jedes Paares ist so gewählt, daß das Rohr 16 mit möglichst geringem Spiel zwischen ihnen gehalten wird. Die Oberfläche der Führungsrollen 18 ist an den kreisförmigen Umfang des Rohrs 16 angepaßt. Im Bewegungsbereich des Rohrs 16 sind die Bügel 12 seitlich angesetzt, um Raum für das Rohr 16 zu schaffen.In the space between the guide rail 10 and the building B is a pipe 16 immediately behind the guide rail 10 supported by two pairs of guide rollers 18 so that the Pipe 16 is displaceable parallel to the guide rail 10, i.e. can be pulled out upwards and retracted downwards. each For this purpose, a pair of guide rollers 18 is on a carrier plate 20 mounted, which is attached to the back of the guide rail 10 is. The guide rollers 18 sit on stub axles 22, the perpendicular to the guide rail 10 and the steps 14th stand. The distance between the guide rollers 18 of each pair is so chosen that the tube 16 with as little play as possible between is held to them. The surface of the guide rollers 18 is adapted to the circular circumference of the tube 16. In the range of motion of the tube 16, the bracket 12 are attached laterally, to make room for the tube 16.

Längs des Rohres 16 ist ein Verlängerungsstück 24 mittels Distanzstücken 26 befestigt. Das Verlängerungsstück 24 ist ein Abschnitt der gleichen Profilschienen wie die Führungsschiene 10. Die Länge der Distanzstücke 26 ist so gewählt, daß das Verlängerungsstück 24 von dem Rohr 16 den gleichen Abstand hat, in dem das Rohr 16 hinter der Führungsschiene gelagert ist. Wenn das Rohr daher um seine Längsachse um 180° gedreht wird, so fluchtet das Verlängerungsstück 24 mit der Führungsschiene 10. Am oberen Ende der Führungsschiene 10 sind Zentrierungslaschen 28 angebracht, in die das Verlängerungsstück 24 eingesetzt werden kann, so daß ein Verdrehen des Verlängerungsstückes 24 gegenüber der Führungsschiene 10 verhindert wird und eine Fangeinrichtung die Verbindungsstelle zwischen Führungsschiene 10 und Verlängerungsstück 24 sicher durchfahren kann.Along the tube 16 is an extension piece 24 by means of Spacers 26 attached. The extension piece 24 is a Section of the same profile rails as the guide rail 10. The length of the spacers 26 is chosen so that the Extension piece 24 from the tube 16 the same distance has, in which the tube 16 is mounted behind the guide rail is. If the tube is therefore rotated by 180 ° about its longitudinal axis the extension piece 24 is aligned with the guide rail 10. At the upper end of the guide rail 10 are centering tabs 28 attached, in which the extension piece 24 can be used so that twisting of the extension piece 24 prevented relative to the guide rail 10 and a safety device the connection point between Drive through guide rail 10 and extension piece 24 safely can.

Das Verlängerungsstück 24 erstreckt sich nicht über die gesamte Länge des Rohrs 16. Am unteren Ende des Rohrs 16 ist vielmehr eine Länge frei, die etwas größer ist als der Abstand der beiden Paare von Führungsrollen 18, so daß das Rohr 16 immer von beiden Paaren von Führungsrollen 18 gehalten wird, wenn das Verlängerungsstück 24 mit dem oberen Ende der Führungsschiene 10 verbunden wird. Über das obere Ende des Rohrs 16 kann das Verlängerungsstück 24 etwas vorstehen und an dieser Stelle ist auch ein Haltegriff 30 vorgesehen, der der Einfachheit halber die Form eines Tritts 14 haben kann. Ansonsten sind an dem Verlängerungsstück 24 keine weiteren Tritte oder Haltegriffe vorgesehen, da diese beim Versenken des Rohrs 16 stören würden. In der versenkten Position des Rohrs 16 sitzt der Haltegriff 30 auf den obersten Führungsrollen 18 auf. Am unteren Ende des Rohrs 16 befindet sich ein nicht dargestellter Anschlag, der verhindert, daß das Rohr 16 vollständig herausgezogen werden kann.The extension piece 24 does not extend over the entire Length of tube 16. At the bottom of tube 16 is rather a free length that is slightly larger than the distance of the two pairs of guide rollers 18 so that the tube 16 always is held by both pairs of guide rollers 18, if the extension piece 24 with the upper end of the guide rail 10 is connected. Over the top of the tube 16, the extension piece 24 can protrude somewhat and on this A handle 30 is also provided for simplicity may have the shape of a step 14. Otherwise are no further steps or on the extension piece 24 Handles are provided, as they are 16 when the tube is sunk would disturb. Sits in the lowered position of the tube 16 the handle 30 on the top guide rollers 18. At the The lower end of the tube 16 is a not shown Stop that prevents the tube 16 from being pulled out completely can be.

Das Verlängerungsstück 24 kann zwei stabile Positionen einnehmen. In der ersten Position ist es versenkt, wobei das obere Ende des Verbindungsstücks 24 und auch des Rohrs 16 nicht oder nur minimal über das obere Ende der Führungsschiene 10 vorsteht. Am Haltegriff 30 kann das Verlängerungsstück 24 aus dieser ersten Position nach oben gezogen werden. Das Rohr 16 wird dabei durch die Führungsrollen 18 geführt. Die Distanzstücke 26 sind so bemessen, daß sie auf der freien Seite der Führungsrollen 18 zwischen diesen hindurchlaufen können. wenn das Verlängerungsstück 24 vollständig herausgezogen ist, wird es mit dem Rohr 16 um 180° um die Längsachse des Rohrs 16 verschwenkt und wird dann mittels der Zentrierungslaschen 28 auf das obere Ende der Führungsschiene 10 aufgesteckt. Zwischen den Führungsrollen 18 und dem Rohr 16 besteht ein ausreichendes Spiel, um das Rohr 16 zwischen den Führungsrollen 18 drehen zu können. In der zweiten, ausgefahrenen Position steht das Verlängerungsstück 24 mindestens 1 m über die Kante K des Bauwerks B vor. Je nach dem Anwendungsfall des Steigschutzsystems ist am oberen Ende der Führungsschiene 10 und des Verlängerungsstücks 24 noch eine Ausfahrsicherung vorgesehen, die verhindert, daß die in der Führungsschiene 10 und dem Verlängerungsstück 24 geführte Fangeinrichtung versehentlich aus deren oberen Enden herausgezogen wird. The extension piece 24 can assume two stable positions. In the first position it is sunk, which is upper end of the connector 24 and also the tube 16th not or only minimally over the upper end of the guide rail 10 stands out. On the handle 30, the extension piece 24 be pulled up from this first position. The pipe 16 is guided by the guide rollers 18. The Spacers 26 are dimensioned so that they are on the free Run side of the guide rollers 18 between them can. when the extension piece 24 is pulled out completely is, it is with the tube 16 by 180 ° around the longitudinal axis of the Tube 16 is pivoted and is then by means of the centering tabs 28 slipped onto the upper end of the guide rail 10. There is between the guide rollers 18 and the tube 16 a sufficient clearance to the tube 16 between the guide rollers 18 to be able to rotate. In the second, extended position the extension piece 24 is at least 1 m above the Edge K of building B. Depending on the application of the Fall protection system is at the upper end of the guide rail 10 and the extension piece 24 still an extension protection provided, which prevents that in the guide rail 10th and the extension piece 24 guiding device accidentally is pulled out of their upper ends.

Wird das beschriebene Absturzsicherungssystem beispielsweise für einen Kanalschacht verwendet, so wird nach dem Öffnen des Schachtes das Verlängerungsstück 24 herausgezogen, um 180° verschwenkt und auf die Führungsschiene 10 aufgesteckt. Danach wird die Fangeinrichtung oben in das Verlängerungsstück 24 eingesetzt und der Benutzer kann dann gesichert in den Schacht absteigen.For example, the fall protection system described used for a manhole, after opening the Shaft the extension piece 24 pulled out by 180 ° pivoted and attached to the guide rail 10. After that the catching device is at the top in the extension piece 24 inserted and the user can then be secured in the shaft dismount.
