Abstract

Stepping platforms, like storage platforms suspendable on a ladder, are known from the state of the art. However, these are not variable in use and in particular cannot simultaneously meet both functions. The invention provides, that a suspension link is supported on one end of a plate with a peripheral edge, while a mounting element is provided on the other end, which mounting element can include two mounting plates, which are supported pivotally on the outside of the plate and include a recess into which a ladder crosspiece is receivable. The inventive ladder platform can be used as an accessory for all types of ladders.

Description

Die Erfindung bezieht sich auf ein Leiterpodest mit einer Platte, welche einen umlaufenden, sich von einer Seite der Platte erstreckenden Rand umfaßt und an ihrem ersten Ende auf eine Sprosse einer Leiter auflegbar ist, und mit einem Hängebügel, der an dem zweiten Ende der Platte gelagert und an eine Sprosse der Leiter anhängbar ist, wobei an dem ersten Ende der Platte ein Halterungselement vorgesehen ist. welches formschlüssig mit der Sprosse in Eingriff bringbar ist.The invention relates to a ladder platform with a plate, which comprises a peripheral edge extending from one side of the plate and can be placed at its first end on a rung of a ladder, and with a hanging bracket which is mounted on the second end of the plate and can be attached to a rung of the ladder, a holding element being provided at the first end of the plate. which can be positively engaged with the rung.

Es sind aus dem Stand der Technik vielfältige Ausgestaltungsformen von Leiterpodesten bekannt, welche dazu dienen, eine Trittplattform zu bilden, auf welcher sich eine Bedienungsperson aufstellen kann, um einen sichereren Stand auf der Leiter zu haben und um bei einer längeren Verweildauer auf der Leiter einen bequemeren Stand zu haben.Various designs of ladder platforms are known from the prior art, which serve to form a step platform on which an operator can stand in order to have a more secure stand on the ladder and to be more comfortable with a longer stay on the ladder Stand.

Weiterhin sind Leiterpodeste bekannt, welche lediglich der Ablage von Gegenständen oder Werkzeugen dienen, beispielsweise eines Farbkübels oder von zu montierenden Bauteilen.Furthermore, ladder platforms are known which only serve to store objects or tools, for example a paint bucket or components to be assembled.

Ein Leiterpodest der eingangs beschriebenen Art ist aus der US-A- 25 00 559 bereits bekannt. Es erweist sich bei dieser vorveröffentlichten Anordnung als nachteilig, daß bei Verwendung der Platte als Ablage für Werkzeuge oder ähnliches kein Rand vorhanden ist, welcher das Herunterfallen oder Herunterrollen der Werkzeuge oder Gegenstände verhindert. Andererseits erweisen sich die bekannten Podeste, welche zum Zwecke der Ablage von Gegenständen geschaffen wurden, nicht als Trittpodeste, da der vorhandene Rand den Auftrittvorgang erheblich stört.A ladder platform of the type described above is already known from US-A-25 00 559. It proves disadvantageous in this previously published arrangement that when the plate is used as a shelf for tools or the like there is no edge which prevents the tools or objects from falling or rolling off. On the other hand, the known platforms, which were created for the purpose of storing objects, do not prove to be pedestals, since the existing edge considerably interferes with the treading process.

Aus der US-A- 44 37 544 ist es auch bereits bekannt, daß die Platte nicht auf eine Sprosse aufgelegt wird, sondern mit schlitzförmigen Ausnehmungen versehen ist, die über die Sprosse geschoben werden können; beiderseits der Platte verhindert ein separater Sicherungshaken ein selbsttätiges Lösen der Platte von der Sprosse. Auch eine solche Anordnung ist nicht sowohl als Trittpodest als auch als Werkzeugablage zu verwenden.From US-A-44 37 544 it is also already known that the plate is not placed on a rung, but is provided with slot-shaped recesses that can be pushed over the rung; a separate safety hook on both sides of the plate prevents the plate from automatically detaching from the rung. Such an arrangement is also not to be used both as a step platform and as a tool rest.

Der Erfindung liegt die Aufgabe zugrunde, ein Leiterpodest der eingangs genannten Art zu schaffen, welches bei einfachem Aufbau und betriebssicherer Handhabbarkeit sowohl als Trittplattform als auch als Ablagepodest verwendet werden kann.The invention has for its object to provide a ladder platform of the type mentioned, which can be used both as a step platform and as a storage platform with a simple structure and reliable handling.

Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß das Halterungselement zwei im wesentlichen U-förmige, jeweils eine Ausnehmung zum Aufstecken auf die Sprosse bildende Halterungsplatten umfaßt, deren Basisbereich jeweils an der Außenseite des Randes um eine zu der Platte parallele Achse schwenkbar gelagert ist.According to the invention the object is achieved in that the mounting element comprises two substantially U-shaped mounting plates, each forming a recess for attachment to the rung, the base region of which is pivotally mounted on the outside of the edge about an axis parallel to the plate.

Das erfindungsgemäße Leiterpodest zeichnet sich durch eine Reihe erheblicher Vorteile aus. Die erfindungsgemäße Platte ist an einer Seite mit einem umlaufenden Rand versehen, so daß die Platte die Form einer flachen Schale oder einer eckigen Schüssel einnimmt. Die andere Seite der erfindungsgemäßen Platte ist völlig eben, so daß es ohne Störungen möglich ist, sich auf die Platte zu stellen, ohne daß hierbei auf einen Rand getreten werden müßte. Durch die ebene Ausgestaltung der Platte ist es weiterhin in besonders einfacher Weise möglich, die Trittoberfläche der Platte in geeigneter Weise zu beschichten, beispielsweise mit einem Belag zur Rutschverhinderung.The ladder platform according to the invention is characterized by a number of considerable advantages. The plate of the invention is provided on one side with a peripheral edge, so that the plate takes the form of a flat bowl or an angular bowl. The other side of the plate according to the invention is completely flat, so that it is possible to stand on the plate without interference, without having to step on an edge. Due to the flat design of the plate, it is also possible in a particularly simple manner to coat the tread surface of the plate in a suitable manner, for example with a covering to prevent slipping.

Durch die Lagerung der Platte mittels des mit einer Sprosse in Eingriff bringbaren Halterungselements ist es auf einfache und sichere Weise möglich, die Platte zu wenden, um einmal die völlig glatte Außenseite, welche als Trittseite dient, nach oben anzuordnen und zum anderen bei Verwendung des Leiterpodestes als Ablage den Rand der Platte nach oben weisen zu lassen.By mounting the plate by means of the bracket element which can be brought into engagement with a rung, it is possible in a simple and safe manner to turn the plate in order to arrange the completely smooth outside, which serves as the step side, upwards and, secondly, when using the ladder platform to have the edge of the plate facing up as a shelf.

Weil das Halterungselement formschlüssig mit einer Sprosse in Eingriff steht, ist stets eine sichere Halterung der Platte gewährleistet, wobei verhindert wird, daß die Platte sich durch Belastungen von der Strebe löst.Because the mounting element is positively engaged with a rung, a secure mounting of the plate is always guaranteed, preventing the plate from being detached from the strut by loads.

Wesentlich für die Erfindung sind die im wesentlichen U-förmigen Halterungsplatten, die an der Platte schwenkbar gelagert sind. Durch die außenseitige Lagerung der Halterungsplatten ist es möglich, diese ohne Störungen relativ zu der Platte zu verschwenken, um die Platte in ihrer Anordnung jeweils umzudrehen. Es ist vorteilhaft, wenn die beiden Halterungsplatten mittels einer Strebe verbunden sind, so daß sichergestellt ist, daß sich jeweils beide Halterungsplatten gleichzeitig mit der Sprosse in Eingriff befinden. Eine Fehlanordnung des erfindungsgemäßen Podestes wird somit ausgeschlossen.Essential to the invention are the substantially U-shaped mounting plates which are pivotally mounted on the plate. Due to the outside storage of the mounting plates, it is possible to pivot them relative to the plate without interference in order to turn the plate over in its arrangement. It is advantageous if the two mounting plates are connected by means of a strut, so that it is ensured that both mounting plates are in engagement with the rung at the same time. A misalignment of the platform according to the invention is thus excluded.

Durch die Ausnehmung in den Halterungsplatten zum Aufstecken auf die Sprosse ist es auf besonders einfache Weise möglich, eine Zuordnung der Halterungsplatten bzw. des Halterungselementes zu der Sprosse zu finden und insbesondere eine formschlüssige Verbindung sicherzustellen. Der U-förmige Querschnitt ermöglicht ein sicheres Aufstecken auf die Sprosse und gewährleistet einen ausreichenden formschlüssigen Kontakt. Weiterhin kann ein erster Schenkel der Halterungsplatte einen in Richtung auf den zweiten Schenkel gerichteten Verriegelungsvorsprung aufweisen, welcher so bemessen ist, daß dieser bei Anlage des ersten Schenkels an eine Seitenfläche der Platte die Sprosse hintergreift und ein Herausrutschen des Halterungselementes von der Sprosse verhindert.Due to the recess in the mounting plates for plugging onto the rung, it is possible in a particularly simple manner to find an assignment of the mounting plates or the mounting element to the rung and, in particular, to ensure a positive connection. The U-shaped cross-section enables it to be securely attached to the rung and ensures sufficient positive contact. Furthermore, a first leg of the mounting plate can have a locking projection directed in the direction of the second leg, which is dimensioned such that it engages behind the rung when the first leg abuts a side face of the plate and prevents the mounting element from slipping out of the rung.

Um eine ausreichende Einführbarkeit der Sprosse in den Innenraum des U-förmigen Halterungsplatten-Profils sicherzustellen, kann der zweite Schenkel mit einer Abschrägung versehen sein. Da üblicherweise bei den heute verwendeten Leitern die Sprossen einen rechteckigen oder quadratischen Querschnitt aufweisen, ist es somit auf besonders einfache Weise möglich, die Sprossen in die Ausnehmung der Halterungsplatte einzuführen und durch geringfügige Verdrehung formschlüssig mit dieser, insbesondere mit dem an dem ersten Schenkel vorgesehenen Verriegelungsvorsprung in Eingriff zu bringen.In order to ensure that the rung can be inserted sufficiently into the interior of the U-shaped mounting plate profile, the second leg can be provided with a bevel. Since the rungs usually have a rectangular or square cross-section in the conductors used today, it is thus possible in a particularly simple manner to insert the rungs into the recess in the mounting plate and to form-fit them by slight twisting, to engage in particular with the locking projection provided on the first leg.

Die Sprosse zur Verbindung der beiden Halterungsplatten ist bevorzugterweise an dem zweiten Schenkel des U-förmigen Querschnitts oder Profils der Halterungsplatte befestigt, um auf diese Weise eine größtmögliche Verstellung oder Verschwenkung der Halterungsplatte sicherzustellen.The rung for connecting the two mounting plates is preferably fastened to the second leg of the U-shaped cross section or profile of the mounting plate, in order to ensure the greatest possible adjustment or pivoting of the mounting plate.

In einer besonders vorteilhaften Ausgestaltung der Erfindung ist die Strebe mittels eines elastischen Elementes von der Sprosse weg vorspannbar. Durch die Vorspannung wird sichergestellt, daß der erste Schenkel und der Verriegelungsvorsprung stets in sicherer Weise gegen die Wandung der Sprosse anliegen. Eine Fehlbedienung wird dabei ausgeschlossen, da die Bedienungsperson beim Aufschieben der Halterungsplatten auf die Sprosse zwangsläufig das elastische Element mit der Sprosse in Eingriff bringen muß, so daß damit automatisch die entsprechende Vorspannkraft aufgebracht wird.In a particularly advantageous embodiment of the invention, the strut can be pretensioned away from the rung by means of an elastic element. The pretensioning ensures that the first leg and the locking projection always rest securely against the wall of the rung. Incorrect operation is excluded, since the operator must inevitably bring the elastic element into engagement with the rung when the mounting plates are slid onto the rung, so that the corresponding pretensioning force is thereby automatically applied.

Dabei kann es sich als günstig erweisen, das elastische Element im mittleren Bereich der Strebe anzuordnen, da bei dieser Ausgestaltung die Verwendung eines einzigen elastischen Elementes, beispielsweise eine Feder, ausreichend sein kann.It may prove advantageous to arrange the elastic element in the central region of the strut, since in this configuration the use of a single elastic element, for example a spring, may be sufficient.

In einer weiteren, besonders günstigen Ausgestaltung der Erfindung umfaßt der Hängebügel zwei zueinander parallele Bügelstreben, die an einem Ende jeweils um eine zur Schwenkachse des Halterungselementes parallele Achse schwenkbar an dem Rand der Platte gelagert sind, wobei die anderen Enden der Bügelstreben jeweils teilkreisförmig umgebogen und mittels einer Querstrebe miteinander verbunden sind.In a further, particularly favorable embodiment of the invention, the hanging bracket comprises two mutually parallel bracket struts which are pivotally mounted at one end on the edge of the plate about an axis parallel to the pivot axis of the mounting element, the other ends of the bracket struts each being bent in a partially circular manner and by means of a cross brace with each other are connected.

Aus der US-A- 44 25 985 ist es zwar bereits bekannt, die Haltebügel miteinander mittels einer Querstrebe zu verbinden. Diese ist jedoch Teil eines U-förmigen Bügels, dessen Stege in der Platte befestigt sind. Damit können die Hängebügel aber nicht ohne weiteres verschwenkt werden, sondern müssen vorher von der Querstrebe getrennt werden. Eine solche Anordnung ist deshalb nicht günstig in den Fällen, in denen die Plattform einer anderen Funktion zugeführt werden soll und die Hängebügel verschwenkt werden müssen.From US-A-44 25 985 it is already known to connect the retaining bracket to one another by means of a cross strut. However, this is part of a U-shaped bracket, the webs of which are fastened in the plate. However, this means that the suspension brackets cannot easily be swiveled, but must first be separated from the cross strut. Such an arrangement is therefore not favorable in cases in which the platform is to be used for another function and the suspension brackets have to be pivoted.

Bei der Ausgestaltungsform des erfindungsgemäßen Hängebügels ist es möglich, diesen, bedingt durch die teilkreisförmige Umbiegung an einer Sprosse anzuhängen, wobei der Bügel die Sprosse entweder von unten her umgreifend angeordnet werden kann oder so an die Sprosse angehängt werden kann, daß er diese von oben umgreift. Durch diese verschiedenen Anhängungsmöglichkeiten ist es möglich, die Platte in verschiedenen Stellungen an einer Leiter anzuhängen, ohne den Hängebügel abnehmen und umwenden zu müssen. Weiterhin ist es erfindungsgemäß nicht erforderlich, zusätzliche Anhängungs- oder Abstützungsvorrichtungen vorzusehen, welche nur in einem Anwendungsfall, entweder als Trittplattform oder als Ablageplattform verwendbar wären.In the embodiment of the hanging bracket according to the invention, it is possible to attach it to a rung due to the part-circular bend, the bracket can either be arranged around the rung from below or attached to the rung so that it engages around it from above . These different attachment options make it possible to attach the plate to a ladder in different positions without having to remove and turn the hanging bracket. Furthermore, according to the invention, it is not necessary to add additional or to provide support devices which could only be used in one application, either as a step platform or as a storage platform.

Weiterhin kann es sich als günstig erweisen, an dem dem Halterungselement zugewandten Rand der Platte eine Ausnehmung vorzusehen, mittels derer die Platte bei Verwendung als Trittplattform zusätzlich mit der Strebe formschlüssig in Eingriff gebracht werden kann.Furthermore, it may prove advantageous to provide a recess on the edge of the plate facing the mounting element, by means of which the plate can additionally be positively engaged with the strut when used as a step platform.

Im nachfolgenden wird die Erfindung anhand eines Ausführungsbeispiels in Verbindung mit der Zeichnung beschrieben. Dabei zeigt:

In den Fig. 1 und 2 ist in der Seitenansicht ein Ausführungsbeispiel des erfindungsgemäßen Leiterpodestes dargestellt.1 and 2, an embodiment of the ladder platform according to the invention is shown in side view.

Die in Zusammenhang mit dem Podest verwendete Leiter umfaßt zwei zueinander parallele Holme 21, welche in üblicher Weise in Form eines rechteckigen Profils ausgebildet sein können. An den Holmen sind in üblicher Weise Sprossen 4 befestigt, welche ebenfalls üblicherweise ein quadratisches Profil aufweisen.The ladder used in connection with the platform comprises two mutually parallel bars 21, which can be designed in the usual way in the form of a rectangular profile. Rungs 4 are fastened to the spars in a conventional manner, which also usually have a square profile.

Das erfindungsgemäße Leiterpodest umfaßt eine Platte 1, welche im wesentlichen quadratisch oder rechteckig ausgebildet ist. An der Platte 1 ist ein umlaufender, sich von einer Seite der Platte aus erstreckender Rand 2 vorgesehen, welcher beispielsweise durch Umbiegung von Bereichen der Platte 1 ausgebildet sein kann. Die Platte 1 bildet mit dem Rand 2 somit, wie insbesondere aus Fig. 2 ersichtlich, eine flache Schale.The ladder platform according to the invention comprises a plate 1 which is essentially square or rectangular. Provided on the plate 1 is a circumferential edge 2 which extends from one side of the plate and which can be formed, for example, by bending regions of the plate 1. The plate 1 thus forms a flat shell with the edge 2, as can be seen in particular from FIG. 2.

Ein erstes Ende 3 der Platte 1 ist schwenkbar mit einem Halterungselement verbunden, welches zwei Halterungsplatten 8 umfaßt, welche seitlich an dem Rand der Platte, und zwar an der Außenseite des Randes 2 so gelagert sind, daß sie um eine Achse 7 schwenkbar sind. Die Achse 7 ist im wesentlichen parallel zu der Ebene der Platte 1 angeordnet.A first end 3 of the plate 1 is pivotally connected to a mounting element which comprises two mounting plates 8 which are mounted laterally on the edge of the plate, namely on the outside of the edge 2, so that they can be pivoted about an axis 7. The axis 7 is arranged essentially parallel to the plane of the plate 1.

Die beiden Halterungsplatten 8 weisen, wie aus den Fig. 1, 2 und 4 ersichtlich ist, einen U-förmigen Querschnitt auf, wobei ein Basisbereich 15 des U-förmigen Querschnittes an dem Rand 2 schwenkbar gelagert ist. Ein erster Schenkel 11 ist an seinem freien Ende mit einem Verriegelungsvorsprung 13 versehen, wobei der erste Schenkel 11 und der Veriegelungsvorsprung 13 jeweils so dimensioniert sind, daß, wie in den Fig. 1 und 2 gezeigt, ein quadratisches Sprossenprofil der Sprosse 4 formschlüssig umgreifbar ist. Zusammen mit dem ersten Schenkel 11 bildet ein zweiter Schenkel 12 eine Ausnehmung 10 der Halterungsplatte 8, welche so bemessen ist, daß die Sprosse 4 ohne Klemmen in die Ausnehmung 10 einführbar ist. Zu diesem Zwecke weist der zweite Schenkel 12 eine Abschrägung 14 auf, welche an dem freien Ende des zweiten Schenkels 12 angeordnet ist und dem ersten Schenkel 11 gegenüberliegt. Um ein Klemmen der Sprosse 4 in sicherer Weise zu verhindern, kann weiterhin an dem Übergang von dem zweiten Schenkel 12 zu dem Basisbereich 15 eine Auskerbung 22 vorgesehen sein, so wie dies in Fig. 4 dargestellt ist.As can be seen from FIGS. 1, 2 and 4, the two mounting plates 8 have a U-shaped cross section, a base region 15 of the U-shaped cross section being pivotably mounted on the edge 2. A first leg 11 is provided at its free end with a locking projection 13, wherein the first leg 11 and the locking projection 13 are each dimensioned such that 1 and 2, a square rung profile of the rung 4 can be gripped in a form-fitting manner. Together with the first leg 11, a second leg 12 forms a recess 10 in the mounting plate 8, which is dimensioned such that the rung 4 can be inserted into the recess 10 without clamping. For this purpose, the second leg 12 has a bevel 14 which is arranged at the free end of the second leg 12 and is opposite the first leg 11. In order to reliably prevent the rung 4 from jamming, a notch 22 can also be provided at the transition from the second leg 12 to the base region 15, as is shown in FIG. 4.

Die beiden zweiten Schenkel 12 sind über eine Strebe 9 verbunden, welche in den Fig. 1, 2 und 4 im Schnitt dargestellt ist. Die Strebe 9 kann ebenfalls einen im wesentlichen U-förmigen Querschitt aufweisen.The two second legs 12 are connected via a strut 9, which is shown in section in FIGS. 1, 2 and 4. The strut 9 can also have a substantially U-shaped cross section.

Um sicherzustellen, daß sich der erste Schenkel 11 und der Verriegelungsvorsprung 13 sowie der Basisbereich 15 in Anlage mit der Sprosse 4 befinden, ist, wie in Fig. 3 dargestellt, im mittleren Bereich der Strebe 9 ein elastisches Element 16 vorgesehen, welches, wie in den Fi.g 1, 2 und 4 gezeigt, in Form einer Druckfeder ausgebildet ist. Das elastische Element 16 stellt sicher, daß der zweite Schenkel 12 der jeweiligen Halterungsplatte 8 von der Sprosse 4 weggedrückt wird.In order to ensure that the first leg 11 and the locking projection 13 and the base region 15 are in contact with the rung 4, as shown in FIG. 3, an elastic element 16 is provided in the central region of the strut 9, which, as in FIG the Fi.g 1, 2 and 4 shown, is in the form of a compression spring. The elastic element 16 ensures that the second leg 12 of the respective mounting plate 8 is pushed away from the rung 4.

Der Rand 2 der Platte 1 weist im Bereich des ersten Endes 3 eine Ausnehmung 23 auf, welche so ausgeformt ist, daß der Rand 2 bei der in Fig. 1 gezeigten Anordnung der Platte 1 formschlüssig mit der Sprosse 4 in Eingriff bringbar ist, um eine zusätzliche Verankerung zu gewährleisten.The edge 2 of the plate 1 has in the region of the first end 3 a recess 23 which is shaped such that the edge 2 can be positively engaged with the rung 4 in the arrangement of the plate 1 shown in FIG to ensure additional anchoring.

Weiterhin ist an der dem Halterungselement gegenüberliegenden Seite der Platte 1 an deren Rand 2 ein Hängebügel 5 gelagert, welcher um eine Achse 18, welche parallel zu der Achse 7 angeordnet ist, schwenkbar ist. Auf diese Weise wird das zweite Ende 6 der Platte 1 gehaltert. Der Hängebügel 5 umfaßt zwei zueinander parallele Bügelstreben 17, welche jeweils an ihren freien Enden 20 teilkreisförmig gebogen und über eine Querstrebe 19 miteinander verbunden sind. Die Enden 20 der Bügelstreben 17 sind in ihrer Biegung so ausgestaltet, daß ein teilweises Umgreifen oder Umschließen einer Sprosse 4 möglich ist.Furthermore, on the side of the plate 1 opposite the mounting element, a suspension bracket 5 is mounted on the edge 2 thereof, which can be pivoted about an axis 18, which is arranged parallel to the axis 7. In this way, the second end 6 of the plate 1 is held. The hanging bracket 5 comprises two mutually parallel bracket struts 17 which are each bent at their free ends 20 in a part-circle and connected to one another via a cross strut 19. The ends 20 of the bow struts 17 are designed in their bend so that a partial gripping or enclosing a rung 4 is possible.

In Fig. 1 ist das erfindungsgemäße Leiterpodest in einer Anordnung dargestellt, in welcher dieses als Trittplattform dient. Dabei weist die Platte 1 nach oben, während der Rand 2 nach unten angeordnet ist. Der Hängebügel 5 ist so an einer Sprosse 4 angehängt, daß er diese von oben zumindest zum Teil umgreift. Weiterhin befindet sich die Ausnehmung 23 des Randes 2 in formschlüssigem Eingriff mit der Sprosse 4. Die beiden Halterungsplatten 8 des Halterungselementes sind über die Sprosse 4 geschoben und umgreifen diese formschlüssig, wobei das elastische Element 16 zu einer Anlage des ersten Schenkels 11, des Verriegelungsvorsprungs 13 und des Basisbereichs 15 an den jeweiligen Seiten der Sprosse 4 führt.In Fig. 1 the ladder platform according to the invention is shown in an arrangement in which it serves as a step platform. The plate 1 points upwards, while the edge 2 is arranged downwards. The hanging bracket 5 is attached to a rung 4 in such a way that it at least partially encompasses it from above. Furthermore, the recess 23 of the edge 2 is in a form-fitting engagement with the rung 4. The two mounting plates 8 of the mounting element are pushed over the rung 4 and encompass it in a form-fitting manner, the elastic element 16 engaging the first leg 11, the locking projection 13 and of the base region 15 on the respective sides of the rung 4.

In Fig. 2 ist eine Anordnung des erfinungsgemäßen Leiterpodestes gezeigt, in welchem dieses als Ablagepodest dient. Zu diesem Zwecke ist die Platte 1 so angeordnet, daß der Rand 2 nach oben hochsteht. Der Hängebügel 5 umgreift eine obenliegende Sprosse 4 der Leiter, während die Halterungsplatten 8 des Halterungselementes wiederum auf eine Sprosse 4 aufgesteckt sind. Auch diesem Fall bewirkt das elastische Element 16 eine Anlage des ersten Schenkels 11, des Verriegelungsvorsprungs 13 und des Basisbereichs 15 gegen die jeweilige Seite der Sprosse 4.An arrangement of the ladder platform according to the invention is shown in FIG. 2, in which it serves as a storage platform. For this purpose, the plate 1 is arranged so that the edge 2 stands up. The hanging bracket 5 encompasses an overhead rung 4 of the ladder, while the mounting plates 8 of the mounting element are in turn attached to a rung 4. In this case too, the elastic element 16 causes the first leg 11, the locking projection 13 and the base region 15 to bear against the respective side of the rung 4.

In Fig. 3 ist eine Draufsicht auf die Strebe 9 und die beiden Halterungsplatten 8 dargestellt, aus welcher insbesondere die Anordnung der beiden Halterungsplatten sowie des elastischen Elementes 16 ersichtlich ist.FIG. 3 shows a top view of the strut 9 and the two mounting plates 8, from which the arrangement of the two mounting plates and the elastic element 16 can be seen in particular.

Die Fig. 4 zeigt eine Schnittansicht entlang der Linie IV-IV von Fig. 3, wobei hierbei nochmals die Ausgestaltung der Halterungsplatten besonders deutlich wird.FIG. 4 shows a sectional view along the line IV-IV of FIG. 3, the configuration of the mounting plates again being particularly clear.

In Fig. 5 ist eine Draufsicht auf die Platte 1 dargestellt, wobei an dieser auf die Darstellung der Halterungsplatten 8 und der Streben 9 verzichtet wurde. Vielmehr ist der Hängebügel 5 im einzelnen dargestellt. Die der Platte 1 zugewandten Enden 24 der Bügelstreben 17 sind entweder in Ausnehmungen des Randes 2 der Platte 1 geführt oder in zusätzlichen, im einzelnen nicht dargestellten Lagerböcken gelagert. Es ist auch möglich, jeweils auf das freie Ende des Endes 24 eine Schraube 25 aufzuschrauben, um ein Herausrutschen der Bügelstreben 17 aus dem Rand 2 zu verhindern.FIG. 5 shows a top view of the plate 1, with the illustration of the mounting plates 8 and the struts 9 being omitted. Rather, the hanging bracket 5 is shown in detail. The ends 24 of the bow struts 17 facing the plate 1 are either guided in recesses in the edge 2 of the plate 1 or are mounted in additional bearing blocks, not shown in detail. It is also possible to screw a screw 25 onto the free end of the end 24 in order to prevent the bow struts 17 from slipping out of the edge 2.

In Fig. 6 ist eine Schnittansicht durch die in Fig. 5 gezeigte Anordnung dargestellt, wobei der Hängebügel 5 insbesondere hinsichtlich der Bügelstreben 16 verküzrt dargestellt ist.FIG. 6 shows a sectional view through the arrangement shown in FIG. 5, the suspension bracket 5 being shown in a shortened manner, in particular with respect to the bracket struts 16.

Durch das erfindungsgemäße Leiterpodest wurde erstmals die Möglichkeit geschaffen, mit nur einem Podest sowohl eine Trittplattform als auch eine Ablageschale auszubilden, wobei es erfindungsgemäß auf besonders einfache Weise möglich ist, diese beiden Benutzungsformen zu wechseln. Weiterhin ist erfindungsgemäß sichergestellt, daß das Leiterpodest stets in sicherer Weise an der Leiter verankert ist, ohne daß die Gefahr besteht, daß sich das Leiterpodest bei Belastung oder während des Betriebs von selbst löst. Weiterhin erweist es sich als besonders günstig, daß das erfindungsgemäßge Leiterpodest sehr geringe Abmessungen aufweist, so daß es im nicht benötigten Zustand platzsparend verräumt werden kann.The ladder platform according to the invention made it possible for the first time to design both a step platform and a storage tray with only one platform, it being possible according to the invention to change these two forms of use in a particularly simple manner. Furthermore, it is ensured according to the invention that the ladder platform is always securely anchored to the ladder without the risk that the ladder platform will come loose on its own during loading or during operation. Furthermore, it proves to be particularly favorable that the ladder platform according to the invention has very small dimensions, so that it can be cleared in a space-saving manner when not in use.

Die Erfindung ist nicht auf das gezeigte Ausführungsbeispiel beschränkt, vielmehr ergeben sich für den Fachmann im Rahmen der Erfindung vielfältige Abwandlungsmöglichkeiten.The invention is not limited to the exemplary embodiment shown, rather there are various possible modifications for the person skilled in the art within the scope of the invention.
