Description

Die vorliegende Erfindung betrifft eine Stehleiter, insbesondere Stufenstehleiter oder Klapptritt, mit einem Steigteil und einem Stützteil, die über wenigstens ein Schwenkgelenk miteinander verbunden sind. Dabei weisen sowohl das Steigteil als auch das Stützteil Holme auf, an deren einem dem Schwenkgelenk entfernten ersten Enden Leiterfüße angebracht sind. Mit diesen Leiterfüßen ruht die Stehleiter im aufgestellten Zustand auf einem Untergrund. Jeder Leiterfuß weist einen ersten Teil und einen zweiten Teil auf. Das erste Teil weist erste Verbindungsstrukturen zur Verbindung mit einem der Holme der Stehleiter und zweite Verbindungsstrukturen zur Verbindung mit dem zweiten Teil auf und das zweite Teil weist Verbindungsstrukturen zur Verbindung mit den zweiten Verbindungsstrukturen und eine Aufstandfläche auf, mit welcher der Leiterfuß im aufgestellten Zustand der Stehleiter auf dem Untergrund ruht.The present invention relates to a stepladder, in particular step ladder or folding step, with a riser and a support member, which are connected to each other via at least one pivot joint. In this case, both the riser part and the support part on spars on which a remote from the pivot joint first ends ladder feet are attached. With these ladder feet, the stepladder rests on an underground in the erected state. Each ladder foot has a first part and a second part. The first part has first connection structures for connection to one of the struts of the stepladder and second connection structures for connection to the second part, and the second part has connection structures for connection to the second connection structures and a contact surface, with which the conductor leg in the erected state of the stepladder resting on the ground.

Eine solche Stehleiter ist aus dem Dokument US 2004/0020715 A1 bekannt. Die Aufstandflächen der zweiten Teile der Leiterfüße der in diesem Dokument offenbarten Stehleiter sind so ausgerichtet, dass sie parallel zum Untergrund liegen und so eine größtmögliche Kontaktfläche mit dem Untergrund haben. Die zweiten Teile der Leiterfüße werden in einem plastischen Zustand an die ersten Teile angeformt. Die zweiten Teile sind aus einem weicheren Kunststoff hergestellt als die ersten Teile. Die Holme des Steigteils der Leiter laufen nach oben aufeinander zu. Das Steigteil hat daher das, was oft als A-Form bezeichnet wird. Zum Ausgleich der sich daraus ergebenden Neigung des rechten Holms und des linken Holms sind die zweiten Teile der Leiterfüße keilförmig oder zumindest keilartig ausgebildet. Der rechte und der linke Leiterfuß unterscheiden sich. Die Konstruktion des ersten Teils des rechten Fußes und des linken Fußes unterscheiden sich. Der rechte und linke Fuß sind daher unterschiedlich. Für die Herstellung der Füße sind daher wenigstens drei Werkzeuge notwendig: Zwei Werkzeuge für die Herstellung der ersten Teile und ein weiteres Werkzeug zur Anbringung und Formung der zweiten Teile der Leiterfüße.Such a stepladder is from the document US 2004/0020715 A1 known. The contact surfaces of the second parts of the ladder feet of the stepladder disclosed in this document are aligned so that they lie parallel to the ground and thus have the greatest possible contact surface with the ground. The second parts of the ladder feet are molded in a plastic state to the first parts. The second parts are made of a softer plastic than the first parts. The spars of the riser part of the ladder run upwards towards each other. The riser therefore has what is often referred to as an A-shape. To compensate for the resulting inclination of the right spar and the left spar, the second parts of the ladder feet are wedge-shaped or at least wedge-shaped. The right and left ladder feet differ. The construction of the first part of the right foot and the left foot are different. The right and left foot are therefore different. For the production of the feet are therefore at least three tools necessary: two tools for the production of the first parts and another tool for attaching and forming the second parts of the ladder feet.

Bei der in dem Dokument US 2004/0020715 A1 offenbarten Stehleiter sind das Steigteil und das Stützteil soweit erkennbar identisch aufgebaut. Beide Leiternteile stehen im aufgestellten Zustand der Leiter mit gleichem Winkel zum Untergrund. Für beide Leiternteile können daher identische Leiterfüße gewählt werden, die auch die Neigung der Leiternteile gegenüber dem Untergrund berücksichtigen. Das erfolgt dadurch, dass eine Anlagefläche der ersten Teile, an denen die zweiten Teile der Leiternfüße anliegen, nicht senkrecht zu einer Längsachse der Holme ist, sondern gegenüber einer Fläche senkrecht zur Längsachse um eine Achse parallel zu den Sprossen der Leiter geneigt ist.When in the document US 2004/0020715 A1 Revealed ladder are the riser and the support member as far as recognizable identically constructed. Both ladder parts are in the erected state of the ladder at the same angle to the ground. Therefore, identical ladder feet can be selected for both ladder sections, which also take into account the inclination of the ladder sections relative to the ground. This is done by a contact surface of the first parts, against which the second parts of the ladder feet are not perpendicular to a longitudinal axis of the spars, but is inclined relative to a surface perpendicular to the longitudinal axis about an axis parallel to the rungs of the ladder.

Darüber hinaus ist aus dem Dokument AU 200300772 A4 eine Anlegeleiter mit Leiterfüßen bekannt, die ebenso ein erstes Teil und ein zweites Teil umfassen. Der zweite Teil hat offenbar einen keilartigen Abschnitt, der den ersten Teil überragt. Durch diesen keilartigen Abschnitt kann die Neigung der Holme einer Anlegeleiter mit A-Form ausgeglichen werden, damit die Aufstandsflächen dieser zweiten Teile mit großer Fläche auf dem Untergrund aufliegen können.In addition, from the document AU 200300772 A4 a ladder with ladder feet known, which also include a first part and a second part. The second part apparently has a wedge-like section that dominates the first part. By this wedge-like section, the inclination of the spars of a ladder with A-shape can be compensated so that the contact surfaces of these second parts can lie with a large area on the ground.

Aus dem Dokument US 2010/0116592 A1 ist eine Leiter gemäß dem Oberbegriff des Anspruchs 1 mit zweiteiligen Leiterfüßen bekannt, bei denen das zweite Teil eine ballige Form hat, die in zwei Richtungen gerundet ist. Durch diese Form kommt es unabhängig vom Winkel der Holme zum Untergrund zu einem punktförmigen oder nahezu punktförmigen Kontakt, aber nicht zu einem großflächigen Kontakt der Leiterfüße mit dem Untergrund.From the document US 2010/0116592 A1 is a ladder according to the preamble of claim 1 with two-part ladder feet known in which the second part has a spherical shape, which is rounded in two directions. This shape, regardless of the angle of the spars to the ground to a punctiform or almost point-like contact, but not to a large-area contact of the ladder feet with the ground.

Aus dem Stand der Technik ist keine Lösung bekannt, wie bei einer Stehleiter mit einem Steigteil und einem Stützteil mit unterschiedlichen Neigungen gegenüber dem Untergrund Leiterfüße konstruiert sein können, die einerseits einen möglichst großen Kontakt mit dem Untergrund im aufgestellten Zustand haben und andererseits mit möglichst wenig Werkzeugen hergestellt werden können.From the prior art, no solution is known as in a stepladder with a riser and a support member with different inclinations relative to the ground ladder feet can be constructed on the one hand have the largest possible contact with the ground in the erected state and on the other hand with as few tools can be produced.

Hier setzt die Erfindung an, deren Aufgabe es ist, eine solche Lösung bereitzustellen.This is where the invention, whose task is to provide such a solution.

Die Aufgabe wird erfindungsgemäß dadurch gelöst, dass alle ersten Teile und wenigstens zwei zweite Teile der Leiterfüße identisch ausgebildet sind und dass die zweiten Teile der Leiterfüße am Steigteil gegenüber den zweiten Teilen der Leiterfüße am Stützteil um 180° bezüglich der ersten Teile gedreht an den ersten Teilen der Leiterfüße angebracht sind, wobei alle zweiten Teile der Leiterfüße im Wesentlichen keilförmig ausgebildet sind.The object is achieved in that all the first parts and at least two second parts of the ladder feet are identical and that the second parts of the ladder feet on the riser relative to the second parts of the ladder feet on the support member by 180 ° with respect to the first parts rotated at the first parts the ladder feet are mounted, wherein all the second parts of the ladder feet are substantially wedge-shaped.

Weitere Ausgestaltungen der Erfindungen ergeben sich aus den Unteransprüchen.Further embodiments of the invention will become apparent from the dependent claims.

Gemäß der Erfindung können alle zweiten Teile der Leiterfüße gleich ausgebildet sein.According to the invention, all second parts of the ladder feet can be made the same.

Ebenso ist es aber auch möglich, zwei Paare von zwei Typen von zweiten Teilen zu verwenden, wobei die Typen von zweiten Teilen achsensymmetrisch zueinander ausgebildet sind und die Symmetrieachse in Längsrichtung der Holme verläuft. Die zweiten Teile des ersten Typs sind dann zum Beispiel an dem rechten Holm des Steigteils und an dem linken Holm des Stützteils angebracht. Die zweiten Teile des zweiten Typs sind dann zum Beispiel an dem linken Holm des Steigteils und an dem rechten Holm des Stützteils angebracht. Mit einer solchen Anbringung von Leitfüßen mit zweiten Teilen zweier Typen ist es möglich, sowohl die Neigung zwischen dem rechten und dem linken Holm, als auch die unterschiedliche Neigung von Steigteil bzw. Stützteil zum Untergrund auszugleichen.However, it is also possible to use two pairs of two types of second parts, wherein the types of second parts are formed axially symmetrical to each other and the axis of symmetry extends in the longitudinal direction of the spars. The second parts of the first type are then attached, for example, to the right leg of the riser and to the left leg of the support. The second parts of the second type are then, for example, on the left Holm of the riser and attached to the right spar of the support member. With such an attachment of Leitfüßen with second parts of two types, it is possible to compensate for both the inclination between the right and left spar, as well as the different inclination of riser or support member to the ground.

Der in der Figur 13 dargestellte Klapptritt S weist ein Steigteil 1 und ein Stützteil 2 auf, die schwenkbar miteinander verbunden sind. Das Steigteil hat Holme 1 1 , die über Stufen 12 miteinander verbunden sind. An den unteren Enden der Holme 11 sind die Leiterfüße 3 für das Steigteil angebracht. Das Stützteil hat ebenfalls Holme 21, die über Querstreben 22 miteinander verbunden sind. Die unteren Enden der Holme 21 sind ebenfalls mit Leiterfüßen 3 versehen. Das Steigteil 1 und das Stützteil 2 schließen im aufgestellten Zustand des Klapptritts S betragsmäßig unterschiedlich große Winkel mit dem Untergrund ein. Die beiden Leiterfüße 3 des Steigteils 1 und die beiden Leiterfüße des Stützteils 2 sind so ausgestaltet, dass die Aufstandsfläche aller Leiterfüße 3 vollständig auf dem Untergrund aufliegen können, wenn der Klapptritt S aufgestellt ist.The Indian FIG. 13 shown folding step S has a riser 1 and a support member 2 which are pivotally connected to each other. The riser has spars 1 1, which are connected via steps 12 together. At the lower ends of the spars 11, the ladder feet 3 are mounted for the riser. The support member also has spars 21 which are interconnected by cross braces 22. The lower ends of the spars 21 are also provided with ladder feet 3. The riser 1 and the support member 2 close in the erected state of the folding S entry in terms of magnitude different angles with the ground. The two ladder feet 3 of the riser 1 and the two ladder feet of the support member 2 are designed so that the footprint of all ladder feet 3 can rest completely on the ground when the folding step S is set up.

Die in den Figuren 1 bis 12 dargestellten Leiterfüße 3 unterscheiden sich, sind aber aus identischen Teilen aufgebaut, nämlich aus einem ersten Teil 31 und einem zweiten Teil 32.The in the FIGS. 1 to 12 shown guide feet 3 are different, but are constructed of identical parts, namely a first part 31 and a second part 32nd

Die ersten Teile 31 der Leiterfüße 3 werden durch Kappen gebildet, die auf das untere Ende der Holme 1 1 , 21 aufgesteckt sind. Die Kappen haben eine Seitenwand 315, die die unteren Enden der Holme 11, 21 umschließen. Die Seitenwände 315 bilden so erste Verbindungsstrukturen, die der Verbindung der ersten Leiterteile 31 mit den Holmen 11, 21 dienen. Ein Boden 316 der Kappen bildet eine Anlagefläche 314, an welcher die zweiten Teile 32 der Leiterfüße 3 anliegen. Die Anlagefläche 314 ist gegenüber einer Längsrichtung der Holme 11,21 um einen Winkel β geneigt. In dem Boden sind Löcher 313 vorgesehen, welche zweite Verbindungsstrukturen der ersten Teile 31 bilden, die zur Verbindung mit den zweiten Teilen 32 vorgesehen sind.The first parts 31 of the ladder feet 3 are formed by caps, which are attached to the lower end of the spars 1 1, 21. The caps have a side wall 315 which enclose the lower ends of the spars 11, 21. The side walls 315 thus form first connection structures which serve to connect the first conductor parts 31 to the uprights 11, 21. A bottom 316 of the caps forms a contact surface 314 against which the second parts 32 of the ladder feet 3 abut. The contact surface 314 is inclined relative to a longitudinal direction of the spars 11,21 by an angle β. Holes 313 are provided in the bottom, forming second connection structures of the first parts 31, which are provided for connection to the second parts 32.

Die zweiten Teile 32 der Leiterfüße 3 sind im wesentlichen keilförmig gebildet. Auf den den ersten Teilen 31 zugewandten Oberseiten der zweiten Teile sind Noppen 323 vorgesehen, die der Verbindung mit den ersten Teilen 31 dienen und Verbindungsstrukturen der zweiten Teile 32 bilden. Die Noppen 323 sind in die Löcher 313 eingepresst. Eine Unterseite der zweiten Teile 32 bildet die Aufstandsfläche 322 der Leiter.The second parts 32 of the ladder feet 3 are formed substantially wedge-shaped. On the first parts 31 facing upper sides of the second parts nubs 323 are provided which serve the connection with the first parts 31 and connecting structures of the second parts 32 form. The knobs 323 are pressed into the holes 313. An underside of the second parts 32 forms the footprint 322 of the conductors.

Sowohl die ersten Teile 31 als auch die zweiten Teile 32 sind flächensymmetrisch zu den Flächen, die durch die Schnittflächen III, III beziehungsweise IX-IX in den Figuren 2 beziehungsweise 8 gekennzeichnet sind.Both the first parts 31 and the second parts 32 are surface-symmetrical to the surfaces passing through the sectional surfaces III, III and IX-IX in the Figures 2 or 8 are marked.

Die Leiterfüße 3 für das Steigteil gemäß den Figuren 1 bis 6 und die Leiterfüße 3 für das Stützteil gemäß der Figuren 7 bis 12 unterscheiden sich lediglich dadurch, dass die zweiten Teile 32 im Fall des Steigteils 1 in einer ersten Montageposition und im Fall des Stützteils 2 in einer zweiten Montageposition an den ersten Teilen 31 angebracht sind. In der zweiten Montageposition ist das zweite Teil 32 bezüglich des ersten Teils 31 um 180° gedreht an dem ersten Teil 31 angebracht. Dadurch ändert sich der Winkel zwischen der Aufstandsfläche 322 zu der Längsrichtung I der Holme 1 1 , 21. Im Fall des Leiterfußes für das Steigteil ist dieser Winkel mit α 1 und im Fall des Leiterfußes für das Stützteil mit α 2 bezeichnet. Durch die unterschiedlichen Winkel α 1 und α 2 ist es möglich, die unterschiedliche Neigung des Steigteils 1 und des Stützteils 2 zum Untergrund auszugleichen, um eine flächige Anlage der Auflagefläche 322 auf dem Untergrund zu erreichen.The ladder feet 3 for the riser in accordance with FIGS. 1 to 6 and the ladder feet 3 for the support member according to FIGS. 7 to 12 differ only in that the second parts 32 are mounted in the case of the riser 1 in a first mounting position and in the case of the support member 2 in a second mounting position on the first parts 31. In the second mounting position, the second part 32 with respect to the first part 31 is rotated by 180 ° attached to the first part 31. As a result, the angle between the footprint 322 to the longitudinal direction I of the spars 1 1, 21. Changes in the case of the ladder foot for the riser part of this angle α 1 and α 2 in the case of the ladder foot for the support member. Due to the different angles α 1 and α 2, it is possible to compensate for the different inclination of the riser part 1 and the support part 2 to the ground in order to achieve a surface contact of the support surface 322 on the ground.
