Definitions
- the present invention relates to a mounted on a roof fall protection for securing a person acting on it, comprising a running rail for fixing a safety cable slidably connected thereto for attachment to a harness of the person working on the roof.
- a solution to be mounted on pitched roofs for example, from the DE 19900038 known.
- These are safety hooks which are provided with a holding arm for attachment to a rafter and which are each provided with a eaves-side eyelet for attaching a safety harness.
- These solutions also allow a horizontal footprint to install, or to form a kind of stairs on a roof by the attachment of several such safety roof hooks.
- a variant of the first mentioned solution according to DE-2343233 and the solution according to DE-A-19900038 the last one described variant is also from the EP1219762 known.
- securing posts are mounted on a rafter and provided with a mounting flange.
- This solution is especially suitable for corrugated roof tiles.
- a fall arrest according to the preamble of claim 1, the solution of which is characterized in that a running rail is formed from a profile rail having a first leg for attachment to a roof, said leg having on one side a receptacle for a roofing material and a, extending over the first leg second leg, which defines with the first leg together a C-shaped track in which a trolley receiving, wherein on the opening side of the track rail, a tread is disposed, while formed by the two legs side surfaces of the C-shaped Running track form the guide surface for a trolley.
- FIG. 1 is the first F of a roof D shown with a ridge beam FB on which the rafters S rest.
- a roofing B is laid on the roof D .
- Such a roof B can be realized in the form of bricks or plates.
- an angle bar 5 is screwed onto the rafters S.
- the one leg of the angle bar is attached to the rafters, while on the perpendicular to the rafter running leg by means of a screw 6 a sliding block 7 is held in a holding groove 8 stores.
- the retaining groove 8 is part of a profile rail 10th
- the fall protection 1 consists of a running rail 2, which is part of the rail 10 and a trolley 3 is held on a safety rope 4.
- the rail 10 has two legs and that a first in the mounting position roof-side leg 11 and a second arranged above parallel to the first leg extending second leg 12. Both legs are designed as double-walled hollow legs.
- the first leg 11 has a lower, roof-side wall 111 and an overlying, upper rail side wall 112. Between these two walls 111 and 112 is a cross-sectionally oval cavity 113. This cavity 113 has a first side in the installed position end wall 114 and a in the installed position eaves-side end wall 115.
- the already mentioned retaining groove 8 is arranged, which is designed approximately c-shaped in cross section with the open side towards the ridge out.
- Both the parallel, roof-side wall 111 and the overlying top wall 112 are above the extended eaves end wall 115 away and these two extensions, namely the roof-side extension 116 and the overlying extending parallel extension 117 together with the eaves-side end wall 115 a receptacle 13.
- This receptacle 13 is designed so that a subsequent to the rail 10 roofing can be pushed into it a bit.
- such a roofing can be a tile or a roof tile.
- the second leg 12 is also designed as already mentioned as a hollow leg. Accordingly, this leg has a roof-side wall 121, which is upper than Guide wall serves and parallel to the upper wall 112 of the first leg 11 extends. Parallel to the upper guide wall 121 extends a top wall 122. Between these two walls 121 and 122 there is a second cavity 123. In cross-section, this cavity 123 is oval. The term oval is here not to be understood in the strictly geometrical sense, but more in the general linguistic use in the sense of an elongated surface which is rounded at both ends. In the present case, both in cross-section oval cavities 113 and 123 of two parallel sides and at both ends each with the same radius closed surfaces designed.
- the top surface 122 of the second leg 12 is provided on the ridge side with an obliquely inclined to the direction of the first leg 11 towards extension 124.
- both the upper guide wall 121 and the top wall 122 is extended and this extension 126 and the extension of the end wall 125 in the direction of the first leg 11 are connected to a stiffening wall 128 with each other.
- the first leg 11 and the second leg 12 are connected in the installed position on the ridge side with a double-walled connecting wall 129 with each other.
- a running rail 2 is formed for a trolley guided therein.
- the track has two Guide surfaces which are formed on the one hand by the outside of the upper wall 112 of the first leg and on the other hand by the second cavity 123 also with respect to the outside surface of the roof-side wall 121 and the upper guide wall.
- the extension 127 of the end wall 125 of the second leg 12 forms a running surface for the movable in the running rail 2 trolley.
- the trolley 3 consists of a chassis plate 30 which is angled at 90 ° to a longitudinal edge to a stiffening edge 31.
- This stiffening edge 31 has a rear and a front stiffened bearing cheek 32.
- Both bearing cheeks 32 are penetrated by guide shafts 33.
- guide rollers 34 are mounted on both sides.
- In the chassis plate 30 two spaced bearing bolts 35 are arranged.
- On each bearing pin 35, a roller 36 is held.
- a window 37 is punched out and bent by 90 ° on the side on which the bearing pins 35 and rollers 36 are located. For this part of the window is bent by 90 °, a Seil Unitsinate 38 is formed.
- the guide rollers 34 have a diameter which at least approximately correspond to the clear width between the upper wall 112 of the first leg 11 and the lower, roof-side wall 121 of the second leg 12.
- the two in this view behind each other rollers 36 run on the inside of the extension 127 of the end wall 125 of the second leg 12.
- This safety rope 4 may be, for example, a wire rope, which only serves to fasten the actual safety rope 4 before use and pull it through the rope guide eyelet 38. Accordingly, then this rope 4 must be about twice as long as the fall line of the roof.
- a working on the roof person who rises from the eaves on the roof can now attach the effective, brought by the working person safety rope to the safety rope 4 and pull up by means of this rope 4 the effective safety rope which has a stop pin up to Seil Equipmentsinate 38 , Then he is connected to the inventive fall protection. However, if the person working on the roof enters the roof through a roof hatch close to the roof, they can fix their safety rope 4 directly to the cable guide eye 38.
- the harness that uses the person working on the roof is not part of the invention and is not counted here as part of the fall protection understood here.
- the harness may, for example, have a reeling mechanism similar to a seat belt in the car during a fast unwinding blocked.
- the same fall arrester according to the present invention may of course also be arranged on a flat roof.
- two oppositely directed profile rails 10 will be arranged by means of corresponding angle strips 5 in the central longitudinal direction of the roof.
- these rails then have to be less long than the flat roof is long.
- the ends of the rails are provided with an end cap forming a stop.
- This end cover can in principle be welded on, but preferably this end cover plate will be screwed on so that, if necessary, the trolley can also be replaced.
- the receptacle 13 is used to insert therein a roof plate or insulation board.
- the inclined extension 124 serves to provide a sealing cover over the ridge that eliminates the ridge tiles. It will thus be connected to each other on two sloping sides a rail by a curved cover plate. This can also be used on a flat roof like this. However, if you design this cover plate trough-shaped, the cover plate may additionally have the function of a collecting trough.

Abstract
Description
Die vorliegende Erfindung betrifft eine auf einem Dach zu montierende Absturzsicherung zur Sicherung einer darauf tätigen Person, umfassend eine Laufschiene zur Befestigung eines damit verschiebbar verbundenen Sicherheitsseiles zur Befestigung an einem Gurtzeug der auf dem Dach tätigen Person.The present invention relates to a mounted on a roof fall protection for securing a person acting on it, comprising a running rail for fixing a safety cable slidably connected thereto for attachment to a harness of the person working on the roof.
Jedes Jahr geschehen unzählige Unfälle bei Personen, die ungesichert auf einem Dach arbeite und hinunterstürzen. Entsprechend bestehen in verschiedenen Ländern Vorschriften, um auf den Dächern entsprechende Absturzsicherungen anzubringen. Bereits aus der
In Anlehnung daran und in Weiterentwicklung davon ist aus der
Eine auf Schrägdächern zu montierende Lösungen ist beispielsweise auch aus der
Eine Variante der erst genannten Lösung gemäss der
Insbesondere bei Schrägdächern die mit Dachziegeln oder mit Dachplatten bedeckt sind, sind die heute bekannten Lösungen problematisch, da die Pfosten, wie sie heute für Flachdächer angewendet werden, bei Schrägdächer kaum anbringbar sind, ohne dabei die Dichtigkeit des Daches zu gefährden.Especially with pitched roofs which are covered with tiles or roofing tiles, the solutions known today are problematic because the posts, as they are used today for flat roofs, are hardly attachable to pitched roofs, without compromising the tightness of the roof.
Ein weiteres Problem besteht darin, dass die bekannten Absturzsicherungen keine gesicherte Bearbeitung eines gesamten Daches erlaubt. Die auf dem Dach arbeitende Person muss immer wieder, wenn sie ihre Position ändert, die Absturzsicherung lösen und an einem neuen Sicherungsbereich befestigen. Dies ist nicht nur zeitaufwendig, sondern während des Umhängens ist die Person weniger gut oder gar nicht gesichert, je nachdem wie sorgfältig sie dies vornimmt. Beispielsweise sind bei der Lösung der
Es ist daher die Aufgabe der vorliegenden Erfindung eine Absturzsicherung zu schaffen, die ohne Gefährdung einen vergrösserten Bewegungsbereich erlaubt, ohne hierzu das Sicherungsseil auf eine neue Position anzubringen, das somit auch eine Zeitersparnis bringt und zudem eine Lösung anbietet die die Dichtigkeit des Daches gewährleistet und schliesslich sowohl auf Schrägdächer wie auch auf Flachdächer zur Anwendung geeignet ist.It is therefore the object of the present invention to provide a fall protection that allows without danger an increased range of motion, without attaching the safety rope to a new position, which thus also saves time and also offers a solution that ensures the tightness of the roof and finally suitable for use on pitched roofs as well as on flat roofs.
Diese Aufgabe löst eine Absturzsicherung gemäss Oberbegriff des Patentanspruches 1, deren Lösung sich dadurch auszeichnet, dass eine Laufschiene aus einer Profilschiene geformt ist, die einen ersten Schenkel aufweist zur Befestigung auf einem Dach, wobei dieser Schenkel einseitig eine Aufnahme für ein Bedachungsmaterial aufweist und einen, über dem ersten Schenkel verlaufenden zweiten Schenkel, der mit dem ersten Schenkel zusammen eine C-förmige Laufschiene definiert in der eine Laufkatze Aufnahme findet, wobei an der Öffnungsseite der Laufschiene eine Lauffläche angeordnet ist, während die von den beiden Schenkeln geformten Seitenflächen der C-förmigen Laufschiene die Führungsfläche für eine Laufkatze bilden.This object is achieved by a fall arrest according to the preamble of claim 1, the solution of which is characterized in that a running rail is formed from a profile rail having a first leg for attachment to a roof, said leg having on one side a receptacle for a roofing material and a, extending over the first leg second leg, which defines with the first leg together a C-shaped track in which a trolley receiving, wherein on the opening side of the track rail, a tread is disposed, while formed by the two legs side surfaces of the C-shaped Running track form the guide surface for a trolley.
Weitere vorteilhafte Ausgestaltungsmöglichkeiten der Erfindung gehen aus den abhängigen Ansprüchen hervor und sind in der nachfolgenden Beschreibung unter Bezug auf die beiliegenden Zeichnungen erläutert.Further advantageous embodiments of the invention will become apparent from the dependent claims and are explained in the following description with reference to the accompanying drawings.

Vorerst wird nun die Profilschiene 10 detailliert beschrieben wobei hierbei auf die
Bei der Befestigung der Profilschiene 10 an einem Schrägdach wird diese Profilschiene wie bereits anhand der
Der zweite Schenkel 12 ist ebenfalls wie bereits erwähnt als Hohlschenkel gestaltet. Entsprechend weist auch dieser Schenkel eine dachseitige Wand 121 auf, die als obere Führungswand dient und parallel zur oberen Wand 112 des ersten Schenkels 11 verläuft. Parallel über der oberen Führungswand 121 verläuft eine Deckwand 122. Zwischen diesen beiden Wänden 121 und 122 befindet sich ein zweiter Hohlraum 123. Im Querschnitt ist auch dieser Hohlraum 123 oval. Der Begriff oval ist hier nicht im streng geometrischen Sinn zu verstehen, sondern mehr im allgemein sprachlichen Gebrauch im Sinne von einer länglichen Fläche die an beiden Enden gerundet ist. Im vorliegenden Falle sind beide im Querschnitt ovalen Hohlräume 113 und 123 aus zwei parallelen Seiten und an beiden Enden jeweils mit gleichem Radius geschlossenen Flächen gestaltet. Die Deckfläche 122 des zweiten Schenkels 12 ist firstseitig mit einer schräg zur Verlaufsrichtung zum ersten Schenkel 11 hin geneigten Verlängerung 124 versehen. Auf der gegenüberliegenden Seite ist sowohl die obere Führungswand 121 als auch die Deckwand 122 verlängert und diese Verlängerung 126 und die Verlängerung der Abschlusswand 125 in Richtung zum ersten Schenkel 11 hin sind mit einer Versteifungswand 128 miteinander verbunden.The
Der erste Schenkel 11 und der zweite Schenkel 12 sind in der Einbaulage firstseitig mit einer doppelwandigen Verbindungswand 129 miteinander verbunden. So entsteht zwischen der oberen Wand 112 des ersten Schenkels 11 der dachseitigen Wand 121 des zweiten Schenkels 12 und der Verbindungswand 129 eine Laufschiene 2 für eine darin geführte Laufkatze. Die Laufschiene besitzt zwei Führungsflächen, die einerseits durch die Aussenseite der oberen Wand 112 des ersten Schenkels und andererseits durch die in Bezug auf den zweiten Hohlraum 123 ebenfalls aussen liegenden Fläche der dachseitigen Wand 121 bzw. die obere Führungswand gebildet werden. Die Verlängerung 127 der Abschlusswand 125 des zweiten Schenkels 12 bildet eine Lauffläche für die in der Laufschiene 2 beweglich gehaltenen Laufkatze.The

Dieselbe Absturzsicherung gemäss der vorliegenden Erfindung kann selbstverständlich auch auf einem Flachdach angeordnet sein. In diesem Falle wird man in der mittigen Längsrichtung des Daches zwei entgegengesetzt gerichtete Profilschienen 10 mittels entsprechenden Winkelleisten 5 anordnen. Diese Schienen müssen dann selbstverständlich weniger lang sein als das Flachdach lang ist. Hier nicht dargestellt, aber für den Fachmann selbstverständlich, sind die Enden der Profilschienen mit einer einen Anschlag bildenden Endabdeckung versehen. Diese Endabdeckung kann im Prinzip aufgeschweisst sein, bevorzugterweise jedoch wird man diese Endabdeckplatte aufgeschraubt gestalten, so dass gegebenenfalls auch die Laufkatze ausgewechselt werden kann. Auch auf einem Flachdach dient die Aufnahme 13 dazu um darin eine Dachplatte oder Isolationsplatte einzuschieben.The same fall arrester according to the present invention may of course also be arranged on a flat roof. In this case, two oppositely directed profile rails 10 will be arranged by means of corresponding angle strips 5 in the central longitudinal direction of the roof. Of course, these rails then have to be less long than the flat roof is long. Not shown here, but of course for the expert, the ends of the rails are provided with an end cap forming a stop. This end cover can in principle be welded on, but preferably this end cover plate will be screwed on so that, if necessary, the trolley can also be replaced. Also, on a flat roof, the
Die geneigte Verlängerung 124 dient dazu, um über den First hinweg eine dichtende Abdeckung anzubringen, die die Firstziegel überflüssig machen. Man wird somit an beiden Schrägseiten je eine Profilschiene durch ein gewölbtes Deckblech miteinander verbinden. Dies kann auch auf einem Flachdach so verwendet werden. Gestaltet man dieses Deckblech jedoch trogförmig, so kann das Deckblech zusätzlich die Funktion einer Sammelrinne haben.The
