Description

Die Erfindung betrifft eine Vorrichtung zum Transport von Baumaterial, wie Dachziegeln u. dgl., auf einem teilweise ungedeckten Dach,The invention relates to a device for transporting building materials, such as roof tiles and. Like., on a partially uncovered roof,

  • - mit einer in Dachneigungsebene liegenden Basisfläche,- with a base surface lying in the roof pitch level,
  • - mit wenigstens einem im Bereich der Oberkante der Basisfläche befestigten Winkelrollensatz,with at least one set of angled rollers fastened in the region of the upper edge of the base surface,
  • - mit wenigstens einer an der Unterkante der Basisfläche zur Unterkante senkrecht angebrachten Rolle, und- With at least one roller mounted perpendicular to the lower edge of the base surface to the lower edge, and
  • - mit einer senkrecht auf der Basisfläche stehenden Stützfläche, die oberhalb des oberen Endes der Rolle im Abstand davon angeordnet ist.- With a support surface standing vertically on the base surface, which is arranged above the upper end of the roller at a distance therefrom.

Aus der DE-A Nr. 2325762 ist eine Vorrichtung zum Aufnehmen und Transportieren von Dachziegeln u. dgl. bekannt, die aus einer Ablageebene aus einem etwa parallel zur Dachneigung verlaufenden Profilrahmen besteht, welcher aus zwei ineinander verschiebbaren Teilen gebildet ist, deren Stirnseiten mindestens einseitig Winkelrollensätze aufweisen. Die Winkelrollensätze sind an der in Dachebene oberen Stirnseite angebracht; die untere Stirnseite trägt wenigstens ein weiteres Winkelrollenpaar. Die untere Stirnseite der Ablageebene ist mit senkrecht stehenden Abstützelementen und der Profilrahmen mit weiteren, in ihrer Position veränderbaren Abstützelementen ausgestattet, die nach oben im Abstand vom oberen Rande des unteren Winkelrollenpaares liegen können.From DE-A No. 2325762 a device for receiving and transporting roof tiles and. Like. Known, which consists of a storage level from an approximately parallel to the roof pitch profile frame, which is formed from two mutually displaceable parts, the end faces of which have at least one side angle roller sets. The angle roller sets are attached to the top end face in the roof plane; the lower end carries at least one further pair of angle rollers. The lower end face of the storage level is equipped with vertically standing support elements and the profile frame with further support elements which can be changed in their position and which can lie upwards at a distance from the upper edge of the lower pair of angular rollers.

Die Winkelrollensätze stützen sich auf den parallel angeordneten Dachlatten ab, die beim ungedeckten Dach offenliegen. Die Vorrichtung dient dazu, einen Stapel Dachziegel und anderes, beim Dachdecken benötigtes Baumaterial auf der Dachebene hin und her zu verschieben.The angle roller sets are supported on the parallel roof battens, which are exposed on the uncovered roof. The device is used to move a stack of roof tiles and other building material required for roofing back and forth on the roof level.

Wenn sich auch die vorbekannte Vorrichtung im grossen und ganzen bewährt hat, so weist sie dennoch einige Nachteile auf, die im Interesse des Fortschrittes der Technik verbessert werden sollten. Zum einen ist die Konstruktion relativ schwer, da die ineinander verschiebbaren Profilrahmenteile sich teilweise überlappen und eine relativ aufwendige Konstruktion erfordern. Dies führt auch zu einer nicht unbeträchtlichen Steigerung der Herstellungskosten. Zum anderen besteht bei der Anordnung des Abstützelementes an der unteren Kante, d.h. im Bereich der untenliegenden Winkelrollen, die Gefahr, dass bei relativ steilen Dächern und damit grossem Drehmoment die Vorrichtung bei Belastung aus der Ruhestellung herausdreht und aus der Dachebene kippt.Although the previously known device has largely proven itself, it nevertheless has some disadvantages which should be improved in the interest of the progress of technology. On the one hand, the construction is relatively heavy, since the profile frame parts which can be pushed into one another partially overlap and require a relatively complex construction. This also leads to a not inconsiderable increase in manufacturing costs. On the other hand, there is an arrangement of the support element on the lower edge, i.e. in the area of the angled rollers below, there is the risk that, in the case of relatively steep roofs and thus high torque, the device will rotate out of the rest position and tip over under load and out of the roof plane.

Ferner ist aus der NL-A Nr. 7315944 ein in seinen Abmessungen starrer Dachziegeltransportwagen bekannt, der Winkelrollen an der Ober- und Rollenwalzen an der Unterkante aufweist. Bei diesem Transportwagen ist jedoch nicht die in der Dachneigungsebene liegende Fläche mit einem Anschlag als Transportfläche gestaltet, sondern hierfür ist eine jeweils nach Neigung verstellbare, im Arbeitszustand waagerechte Fläche als Ablagefläche gewählt worden. Bei dieser Vorrichtung ist daher die mögliche Stapel höhe niedriger als bei der erstgenannten, bekannten Vorrichtung, da die aufgestapelten Dachziegel nur von einer Seite, nämlich von ihrer Unterseite her, gestützt werden. Die Verstellbarkeit der Ladefläche macht überdies das Gerät unhandlich.Also known from NL-A No. 7315944 is a roof tile transport wagon which is rigid in its dimensions and has angular rollers on the upper and roller rollers on the lower edge. In this transport trolley, however, the surface lying in the roof pitch plane is not designed as a transport surface with a stop, but instead a surface which is adjustable according to the inclination and which is horizontal in the working state is selected as a storage surface. In this device, the possible stack height is therefore lower than in the first known device, since the stacked roof tiles are only supported from one side, namely from their underside. The adjustability of the loading area also makes the device bulky.

Es stellt sich demnach die Aufgabe, die Arbeitssicherheit der bekannten Geräte zu erhöhen; auf der anderen Seite soll dieses keine Kostenerhöhung, sondern, wenn möglich, noch eine Senkung der Herstellungskosten erbringen, was insbesondere dadurch zu erreichen ist, dass der Rahmen unterhalb der Basisfläche starr gemacht wird.It is therefore the task of increasing the occupational safety of the known devices; on the other hand, this should not bring about an increase in costs but, if possible, a reduction in production costs, which can be achieved in particular by making the frame below the base surface rigid.

Diese Aufgabe wird bei einer Vorrichtung der eingangs genannten Art, bei Verwendung eines starren Rahmens unterhalb der Basisfläche, durch folgende Einzelmassnahmen gelöst:

  • a) die unteren Rollen sind als Walzenrollen mit einer Länge von 300±100 mm ausgestaltet,
  • b) die Basisfläche weist eine Länge von 1500 ±150 mm auf, und
  • c) die Stützflächen-Fusspunkte liegen im Abstand von 250±100 mm von der Oberkante der Walzenrollen.
This object is achieved in a device of the type mentioned at the outset, when using a rigid frame below the base area, by the following individual measures:
  • a) the lower rollers are designed as roller rollers with a length of 300 ± 100 mm,
  • b) the base surface has a length of 1500 ± 150 mm, and
  • c) the support surface base points are at a distance of 250 ± 100 mm from the upper edge of the roller rolls.

Im vorstehenden und im folgenden Teil des Textes sind die Begriffe oben und unten durch die Lage der Vorrichtung auf dem Dach gekennzeichnet, d.h. die zum First zeigenden Teile sind oben, die zur Traufe zeigenden unten.In the above and the following part of the text, the terms above and below are identified by the position of the device on the roof, i.e. the parts facing the ridge are at the top, those facing the eaves below.

Mit der neu konzipierten Vorrichtung gemäss Erfindung wird kein Gestell mehr benötigt, das längenveränderlich ist. Die im Dachausbau notwendigen Abstände der Rollen wegen der unterschiedlichen Abstände der Dachlatten werden ausgeglichen durch die Länge der Rollenwal- ze(n), die auf der nach aussen zeigenden Seite der untenliegenden Dachlatte abläuft bzw. ablaufen. Durch die Versetzung der Stützflächen auf eine bestimmte Lage oberhalb des oberen Endes der Walzenrollen wird gewährleistet, dass auch bei maximaler Belastung der Stützfläche mit Dachziegeln der Drehpunkt und das lastende Drehmoment nie so ungünstig liegen können, dass das Gerät aus einer stabilen Lage herauskippen kann.With the newly designed device according to the invention, a frame that is variable in length is no longer required. The spacing of the rollers required in the roof expansion due to the different spacing of the roof battens is compensated for by the length of the roller roller (s) running or running on the outward-facing side of the roof battens below. Moving the support surfaces to a certain position above the upper end of the roller rollers ensures that, even with maximum load on the support surface with roof tiles, the pivot point and the load torque can never be so unfavorable that the device can tip out of a stable position.

Ein weiterer Vorteil ist, wenn die Abstützfläche auch noch mit einer schräg liegenden Strebe, deren Fuss im Ausdehnungsbereich der Rollenwalzen endet, versehen wird. Hierdurch kann auch noch eine Gewichtsersparnis erreicht werden.A further advantage is if the support surface is also provided with an inclined strut, the foot of which ends in the expansion region of the roller rollers. This can also save weight.

Die genannten Abmessungen der Vorrichtung sind so gewählt, dass die nach den Vorschriften üblichen Dachlattenabstände ausgenutzt werden können. Dabei muss berücksichtigt werden, dass ältere Bauten, auf denen selbstverständlich auch Dachdeckerarbeiten durchgeführt werden müssen, oft andere Dachlattenabstände aufweisen, als sie den heutigen Vorschriften entsprechen. Geht man beispielsweise davon aus, dass die Dachlatten Abstände zwischen 30 und 45 cm aufweisen, so muss die Überstreichungsfläche der Rollenwalzen so beschaffen sein, dass entweder der Abstand von drei oder vier Dachlatten überbrückt wird.The dimensions of the device mentioned are chosen so that the roof slat distances customary according to the regulations can be used. It must be taken into account that older buildings, on which roofing work must of course also be carried out, often have different battens spacings than those that meet today's regulations. If one assumes, for example, that the roof battens are spaced between 30 and 45 cm, the sweep area of the roller rollers must be such that either the distance of three or four roof battens is bridged.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt.An embodiment of the invention is shown in the drawing.

Die Vorrichtung besteht aus einem starren Rahmen 1 aus einem Aluminiumprofilmaterial, das in Rechteckform zusammengeschweisst ist. Der Rahmen 1 weist zwei Längsholme 2, 3 sowie einen oberen und unteren Querholm 4, mit dazu parallel liegenden, mehr im Mittelbereich des Rahmens angeordneten Stützholmen 6, 7 auf. Durch die Holme 4, 5, 6 und 7 wird der Rahmen 1 in drei Felder aufgeteilt. Die beiden obenliegenden Felder 8, 9 sind von einer Platte 10 überdeckt, die beispielsweise aus 5 mm starkem Aluminiumblech besteht, welches auf die Holme des Rahmens aufgeschraubt ist. Rahmen 1 und Platte 10 bilden zusammen die Basisfläche der neuerungsgemässen Vorrichtung. Auf der Basisfläche, und zwar im Bereich des Stützholmes 7, ragt eine Stützfläche 12 auf, welche aus einem U-förmigen Profilrahmen 13 besteht, dessen Fusspunkte 17 an den Holmen 2 bzw. 3 festgeschweisst sind. Auch der Profilrahmen 13 ist mit einer Blechplatte 14 belegt, so dass sich eine praktisch geschlossene, winkelige Fläche zwischen den beiden Blechplatten 10 und 14 ergibt, die den eigentlichen Transportraum der Vorrichtung aufspannt. Dabei ist beispielsweise der Abstand der beiden Holme 4, 5 mit 1500 mm und der Abstand der Fusspunkte 17 der Stützfläche vom oberen Holm 4 mit 950 mm bemessen.The device consists of a rigid frame 1 made of an aluminum profile material which is welded together in a rectangular shape. The frame 1 has two longitudinal spars 2, 3 and an upper and lower transverse spar 4, with supporting spars 6, 7 lying parallel thereto and arranged more in the central region of the frame. The bars 1, 4, 5, 6 and 7 divide the frame 1 into three fields. The two overhead fields 8, 9 are covered by a plate 10, which consists for example of 5 mm thick aluminum sheet which is screwed onto the spars of the frame. Frame 1 and plate 10 together form the base surface of the device according to the innovation. On the base surface, in the region of the support spar 7, a support surface 12 protrudes, which consists of a U-shaped profile frame 13, the base points 17 of which are welded to the spars 2 and 3, respectively. The profile frame 13 is also covered with a sheet metal plate 14, so that there is a practically closed, angular surface between the two sheet metal plates 10 and 14, which spans the actual transport space of the device. For example, the distance between the two spars 4, 5 is 1500 mm and the distance between the base points 17 of the support surface from the upper spar 4 is 950 mm.

Unterhalb des oberen Querholmes 4 sind im Bereich der beiden Längsholme 2,3 jeweils Winkelrollensätze 15,16 angebracht, die jeweils aus einer Rolle 15' bestehen, die auf der Oberseite einer Dachlatte 18 abrollt, und einer senkrecht dazu stehenden Stützwalze 15", die auf der Aussenseite der Dachlatte rollt. Es sei darauf hingewiesen, dass anstelle der Rollen auch entsprechend ausgestattete Gleitelemente verwendet werden können.Beneath the upper cross member 4, in the area of the two longitudinal members 2, 3, there are attached respective sets of angle rollers 15, 16, each of which consists of a roller 15 'that rolls on the top of a roof batten 18, and a support roller 15 "that is perpendicular to it and that opens on the outside of the roof batten It should be noted that instead of the rollers, appropriately equipped sliding elements can also be used.

Am unteren Ende des Rahmens 1, d.h. im Bereich des Querholmes 5, sind unterhalb des Längsholmes 2 bzw. 3 jeweils längliche Rollenwalzen 19, 19' angebracht, welche sich jeweils auf die dritte oder vierte, unterhalb der Dachlatte 18 liegende weitere Dachlatte 20 abstützen. Dabei ist die Länge der Rollenwalzen so bemessen, dass verschiedene, in der Praxis vorkommende Abstände von Dachlatten überbrückt werden können. Im gezeichneten Beispiel ist die Nutzlänge der Walzen 19 etwa 300 mm. Die Walzen sind als längliche, zylindrische Hohlkörper gestaltet, die von Lagerböcken 21,22 gehalten, in Draufsicht praktisch völlig von den Holmen 2, 3 überdeckt sind.At the bottom of frame 1, i.e. in the area of the crossbar 5, elongated roller rollers 19, 19 'are attached below the longitudinal spar 2 and 3, respectively, which are each supported on the third or fourth further roof battens 20 located below the roof battens 18. The length of the roller rollers is dimensioned so that different, in practice, distances between roof battens can be bridged. In the example shown, the useful length of the rollers 19 is approximately 300 mm. The rollers are designed as elongated, cylindrical hollow bodies which are held by bearing blocks 21, 22 and are practically completely covered by the spars 2, 3 in plan view.

Der Profilrahmen 13 der Stützfläche 12 wird mit Streben 23, 24, deren Fusspunkte im Ausdehnungsbereich der Rollenwalzen 19,19' enden, auf den Längsholmen 2, 3 abgestützt. Ferner sind an den Seiten des Rahmens 1 Handgriffe bzw. Zugösen angebracht.The profile frame 13 of the support surface 12 is supported on the longitudinal spars 2, 3 with struts 23, 24, the base points of which end in the expansion region of the roller rollers 19, 19 '. Furthermore, 1 handles or drawbar eyes are attached to the sides of the frame.

Aus der Figur ist deutlich zu erkennen, dass die zur Unterkante, d.h. zum Querholm 5, senkrechten Rollenwalzen 19,19' so angebracht sind, dass die Stützfläche nach oben im Abstand von den oberen Enden 28 davon befestigt sind. Im vorliegenden Beispiel beträgt der Abstand etwa 260 mm. Wie eingangs betont, können die Abmessungen innerhalb gewisser Grenzen verändert werden, wenn darauf geachtet wird, dass auch bei grösster Belastung der Stützfläche kein Überkippen der Vorrichtung aus der Dachneigung heraus erfolgen kann.From the figure it can be clearly seen that the bottom edge, i.e. to the cross bar 5, vertical roller rollers 19, 19 'are attached in such a way that the support surface is fastened upwards at a distance from the upper ends 28 thereof. In the present example, the distance is approximately 260 mm. As emphasized at the beginning, the dimensions can be changed within certain limits if care is taken to ensure that the device cannot tip over from the roof pitch even when the supporting surface is subjected to the greatest stress.
