DACHAUFLIEGELEITERUtility model application
ROOF LADDER
Dachaufliegeleitern sind Leitern, welche auf Schrägdächern aufgelegt werden, um einfache Arbeiten darauf verrichten zu können. Gehalten werden diese Leitern in der Regel von Dachhaken, welche in die vorhandenen Dachlatten eingehängt werden. Eine besondere Biegung wird durch die Überlappung der Dachziegel hindurch geführt und die Dachleiter wird an eine der Sprossen in die Biegung eingehängt .Roof ladders are ladders that are placed on sloping roofs in order to be able to carry out simple work on them. These ladders are usually held by roof hooks that are hooked into the existing roof battens. A special bend is made through the overlap of the roof tiles and the roof ladder is hooked into the bend on one of the rungs.
Dachaufliegeleitern sind bekannt aus Holz und aus Aluminium sowie aus anderen Nichteisenmetallen. (Figur 1) Bekannt geworden sind z.B. Alu-Dachleitern mit längsverlaufendem Flachalu als Holme sowie mit Sprossen aus Alu-Blechstreifen (Figur 1). Die Sprossen werden gebogen um den von der DIN und Berufsgenossenschaft geforderten Abstand vom Dach zur Unterkante der Sprossen zu erreichen (Figur 2 (I)). Des weiteren sind Alu-Dachaufliegeleitern bekannt geworden, welche einfache Rechteckrohre in der Größe von ca. 40x20 mm als Holme vorweisen (Figur 2 (2)). In jedem Falle werden die Sprossen mittels Nieten oder Schrauben auf den Flachalu-Holmen oder Rechteckholmen angenietet (3). Da jedoch die Konstruktion sehr leicht sein muß, sind die Wandstärken in jedem Fall sehr dünnwandig.Roof ladders are known to be made of wood and aluminum as well as other non-ferrous metals. (Figure 1) Aluminum roof ladders with longitudinal flat aluminum as the stiles and with rungs made of aluminum sheet strips (Figure 1) have become known. The rungs are bent to achieve the distance from the roof to the lower edge of the rungs required by DIN and the trade association (Figure 2 (I)). Aluminum roof ladders have also become known which have simple rectangular tubes measuring approx. 40x20 mm as the stiles (Figure 2 (2)). In any case, the rungs are riveted to the flat aluminum stiles or rectangular stiles using rivets or screws (3). However, since the construction has to be very light, the wall thicknesses are always very thin.
Da die Leitern immer auf den Dachziegeln aufgelegt werden, tritt das Problem der Beschädigung der Dachziegel, durch das Gewicht der Leiter und der Person welche diese Leiter benützt auf, deshalb sind auch Konstruktionen bekannt, bei welchen unter der Leiter Gummi- oder Holzunterlagen befestigt werden.Since the ladders are always placed on the roof tiles, the problem of damage to the roof tiles arises due to the weight of the ladder and the person using it, which is why there are also constructions in which rubber or wooden pads are attached under the ladder.
Die Neuerfindung hat sich zur Aufgabe gemacht, ein Holmprofil für Dachaufliegeleitern zu verwenden, welches sehr leicht ist und Verstärkungen an den Stellen an welchen die Sprossen mit den Holmen vernietet werden (8) vorweist. Das Holmprofil hat einen Wulst an der Außenseite (4) in Höhe der Sprossendicke um Verletzungen durch scharfe Kanten zu vermeiden und um einen Anschlag für die Montage der Sprossen zu erhalten, damit die Montagearbeiten bei der Herstellung der Leiter vereinfacht werden (4). Die Kanten (7) sind zur Stabilisierung der Leiter beim Transport und Benutzung verstärkt.The new invention has set itself the task of using a rail profile for roof ladders that is very light and has reinforcements at the points where the rungs are riveted to the rails (8). The rail profile has a bead on the outside (4) at the height of the rung thickness to prevent injuries from sharp edges and to provide a stop for the assembly of the rungs so that the assembly work when making the ladder is simplified (4). The edges (7) are reinforced to stabilize the ladder during transport and use.
Eine weitere Ausführung des Holmprofils weist an den Seitenflächen links und rechts eine Nut auf (5), um ein speziell dafür passendes Gummiprofil einsetzen zu können, damit die vorbeschriebenen Beschädigungen an den Dachziegeln vermieden werden.Another version of the beam profile has a groove on the left and right side surfaces (5) in order to be able to insert a specially designed rubber profile so that the previously described damage to the roof tiles is avoided.
