Die vorliegende Erfindung betrifft eine Fahrrolle für ein Fahrgerüst mit einem Rad und einem Lager- und Verbindungsmittel, an welchem das Rad gelagert ist und welches zur Verbindung der Fahrrolle mit dem restlichen Fahrgerüst geeignet und eingerichtet ist, wobei das Lager- und Verbindungsmittel ein Rohr umfasst. Die Erfindung betrifft ferner ein Fahrgerüst mit einer solchen Fahrrolle.The present invention relates to a driving roller for a rolling tower with a wheel and a bearing and connecting means on which the wheel is mounted and which is suitable and adapted for connection of the driving roller to the rest of the rolling stand, wherein the bearing and connecting means comprises a tube. The invention further relates to a mobile scaffold with such a driving role.
Aus dem Stand der Technik und aus der Praxis sind Fahrgerüste bekannt. Fahrgerüste werden häufig von Handwerkern, wie zum Beispiel Malern, Lüftungsbauern oder anderen Handwerkern genutzt, um in hohen Räumen Arbeiten an Wänden oder Decken auszuführen. Derartige Fahrgerüste weisen in der Regel Fahrrollen auf, die ein Lager- und Verbindungsmittel mit einem Rohr umfassen. Das Lager- und Verbindungsmittel dient einerseits der Lagerung eines Rades und andererseits der Verbindung des Rades mit dem übrigen Fahrgerüst. Das Rohr hat meist ein Außengewinde, welches in einem Innengewinde am unteren Ende eines Ständers des Gerüstes eingeschraubt ist. Über die Einschraubtiefe kann die Höhe der Fahrrolle eingestellt werden. Dadurch können Unebenheiten im Untergrund ausgeglichen werden.From the state of the art and from practice mobile scaffoldings are known. Mobile scaffolds are often used by craftsmen, such as painters, ventilators or other craftsmen, to carry out work on walls or ceilings in high rooms. Such scaffolds usually have casters, which include a bearing and connecting means with a pipe. The storage and connecting means serves on the one hand the storage of a wheel and on the other hand, the connection of the wheel with the rest of the mobile scaffold. The tube usually has an external thread, which is screwed into an internal thread at the lower end of a stand of the framework. The height of the drive roller can be adjusted via the screw-in depth. As a result, unevenness in the ground can be compensated.
Der Erfindung lag das Problem zu Grunde, eine alternative Verbindung der Fahrrollen mit dem übrigen Gerüst zu finden. Die Fahrrollen sollten insbesondere auch an Ständern eines Gerüstes angebracht werden können, die aus einem rechteckigen Hohlprofil hergestellt sind, wie es zum Beispiel bei der Herstellung von Leitern verwendet wird.The invention was based on the problem to find an alternative connection of the casters with the rest of the framework. The driving rollers should in particular also be able to be mounted on uprights of a scaffold, which are made of a rectangular hollow profile, as used for example in the manufacture of ladders.
Dieses Problem wird erfindungsgemäß dadurch gelöst, dass das Rohr eines Lager- und Verbindungsmittels einer erfindungsgemäßen Fahrrolle einen Längsschlitz aufweist. Dem Längsschlitz gegenüberliegend ist in dem Rohr ein Lochbild mit in Längsrichtung aufeinander folgenden Löchern vorgesehen. Außerdem weist das Lager- und Verbindungsmittel der erfindungsgemäßen Fahrrolle ein Spreizelement und eine Schraube auf. Die Schraube ist von außerhalb des Rohres durch eines der Löcher des Lochbildes hindurchgesteckt und in das Spreizelement eingeschraubt. Durch das Anziehen der Schraube kann das Spreizelement gespreizt werden. Dieses dient der Befestigung der Fahrrolle an dem übrigen Gerüst, wie es noch näher beschrieben wird.This problem is inventively solved in that the tube of a bearing and connecting means of a driving roller according to the invention has a longitudinal slot. The longitudinal slot opposite is in the tube a hole pattern with in the longitudinal direction provided successive holes. In addition, the bearing and connecting means of the driving roller according to the invention on a spreading element and a screw. The screw is inserted from outside the tube through one of the holes of the hole pattern and screwed into the expander. By tightening the screw, the spreader can be spread. This serves to attach the drive roller to the rest of the framework, as will be described in more detail.
Das Rohr kann einen rechteckigen Querschnitt haben und an den Querschnitt eines Längsholmes eines Ständers angepasst sein, der ebenfalls im Querschnitt rechteckig ist. Die Schraube kann eine Sternschraube, Knebelschraube oder ähnliches sein. Das Spreizelement ist überwiegend in dem Rohr des Lager- und Verbindungsmittels vorgesehen. Auf der Innenseite des Rohres kann dem Längsschlitz gegenüberliegend ein Verstärkungselement angeordnet sein. Dadurch kann das Lager- und Verbindungsmittel stabiler ausgebildet sein. Bei dem Verstärkungselement kann es sich um eine Platte handeln, die von innen an der Wand des Rohres angebracht ist.The tube may have a rectangular cross section and be adapted to the cross section of a longitudinal spar of a stator, which is also rectangular in cross section. The screw may be a star screw, thumbscrew or the like. The expansion element is predominantly provided in the tube of the bearing and connecting means. On the inside of the tube, a reinforcing element can be arranged opposite the longitudinal slot. As a result, the bearing and connecting means can be made more stable. The reinforcing element may be a plate which is attached from the inside to the wall of the tube.
Das Lager- und Verbindungsmittel einer erfindungsgemäßen Fahrrolle kann einen Lagerbock aufweisen, an welchem das Rad der Fahrrolle drehbar gelagert ist.

Der Ständer eines erfindungsgemäßen Fahrgerüstes, dass mit einer erfindungsgemäßen Rolle ausgestattet ist, kann zwei Längsholmen und wenigsten zwei Querholme aufweisen, wobei die Längsholme und die Querholme miteinander verbunden sind. Die Querholme können mit ihren Enden in Durchgangslöchern oder Durchbrechungen der Längsholme eingesetzt sein. Zumindest die Enden der Querholme sind hülsenartig, rohrartig oder topfartig ausgebildet und haben somit einen stirnseitig offenen Hohlraum. Außerdem können die Längsholme quer zu ihrer Erstreckungsrichtung angeordnete Sacklöcher oder Durchgangslöcher aufweisen.The stand of a mobile scaffold according to the invention, which is equipped with a roller according to the invention, may have two longitudinal beams and at least two transverse bars, wherein the longitudinal beams and the transverse beams are interconnected. The transverse bars can be inserted with their ends in through holes or openings of the longitudinal bars. At least the ends of the transverse bars are sleeve-like, tubular or pot-shaped and thus have a frontally open cavity. In addition, the longitudinal beams may have transverse to their extension direction arranged blind holes or through holes.
Die Rohre der Fahrrollen können bei einem erfindungsgemäßen Fahrgerüst auf die unteren Enden der Längsholme der Ständer geschoben sein. Die Querholme der Ständer können dabei die Längsschlitze der Rohre der Fahrrollen durchgreifen. Die Spreizelemente der Fahrrollen können in die endseitig offenen Hohlräume in den Enden der Querholme bzw. in die Sacklöcher oder Durchgangslöcher in den Längsholmen eingreifen. Durch ein Anziehen der Schrauben der Fahrrollen werden die Fahrrollen dort fixiert.The tubes of the casters can be pushed at a mobile scaffold according to the invention on the lower ends of the longitudinal bars of the stand. The transverse bars of the stand can pass through the longitudinal slots of the tubes of the casters. The spreading of the driving rollers can engage in the open-ended cavities in the ends of the transverse bars or in the blind holes or through holes in the longitudinal beams. By tightening the screws of the casters, the casters are fixed there.
Bei einem Fahrgerüst mit einer solchen erfindungsgemäßen Fahrrolle kann durch die Wahl des Loches des Lochbildes in dem Rohr der Fahrrolle, durch welches die Schraube hindurch gesteckt wird, die Höhe der Fahrrolle eingestellt werden.In a rolling stand with such a driving roller according to the invention, the height of the driving roller can be adjusted by the choice of the hole of the hole pattern in the tube of the driving roller through which the screw is inserted.
