Der vorliegenden Erfindung liegt die Aufgabe zu Grunde, eine Stehleiter der eingangs genannten Art so weiterzubilden, dass der Bügel im Nutzzustand stabil fixierbar ist, um insbesondere auch schwere Gegenstände wie Weiβ... bindereimer, Schalen o. ä. aufnehmen zu können. Auch soll eine Unverlierbarkeit des Bügels gegeben sein. In einem weiteren Aspekt der Erfindung soll dann, wenn der Bügel nicht benutzt werden soll, ein sicheres Verstauen möglich sein.The present invention is based on the object, a stepladder of the type mentioned in such a way that the bracket is stably fixed in the use state, in particular heavy objects such as white ... bindereimer, trays o. Ä. To be able to record. Also should be given a captive bar. In a further aspect of the invention, when the stirrup is not to be used, secure stowage should be possible.
Zur Lösung der Aufgabe sieht die Erfindung im Wesentlichen vor, dass das Verbindungs- bzw. Schalenelement im Bereich eines jeden ersten Holmes eine Verbindung zu einem Hohlraum des ersten Holmes ermöglichende Durchbrechung aufweist, dass jede Durchbrechung von jeweils einem der Bügelseitenschenkel durchsetzt ist, dass in einer ersten Stellung des Bügels die Bügelseitenschenkel sich innerhalb der Hohlräume der ersten Holme erstrecken und der Querschenkel von dem Verbindungs- bzw. Schalenelement aufgenommen ist oder in dessen Bereich verläuft und dass in der zweiten Stellung des Bügels die Bügelseitenschenkel außerhalb der Hohlräume der ersten Holme verlaufen und sich endseitig an dem Verbindungs- bzw. Schalenelement abstützen, wobei zumindest einer der Bügelseitenschenkel in seinem freien Endbereich einen wirksamen Querschnitt aufweist, der größer als wirksamer Querschnitt der Durchbrechung ist.To solve the problem, the invention essentially provides that the connection or shell element in the region of each first spar has a connection to a cavity of the first spar permitting opening that each opening of each of the strap side legs is interspersed that in one first position of the bracket, the stirrup side legs extend within the cavities of the first spars and the transverse leg is received by or in the region of the connecting or shell element and in the second position of the stirrup the stirrup side legs extend outside the cavities of the first spars and supported at the end of the connecting or shell element, wherein at least one of the strap side legs in its free end region has an effective cross section which is greater than effective cross section of the opening.
Insbesondere weist jedes freie Ende der Bügelseitenschenkel eine entsprechende Querschnittsgeometrie auf, die vorzugsweise durch eine Ummantelung bzw. eine Kappe z. B. aus Kunststoff erzielt wird. Selbstverständlich wird die Erfindung auch dann nicht verlassen, wenn die Querschnittsgeometrie durch Verformung der Enden der Bügelseitenschenkel verwirklicht wird.In particular, each free end of the stirrup side legs has a corresponding cross-sectional geometry, which is preferably formed by a sheathing or a cap z. B. is made of plastic. Of course, the invention will not be abandoned even if the cross-sectional geometry is realized by deformation of the ends of the stirrup side legs.
Aufgrund der erfindungsgemäßen Lehre wird eine Stehleiter mit einem schwenkbaren und in die die Stufen tragenden Holmen hineinschiebbaren Bügel vorgeschlagen, der im Bereich des Schalenelements eine Aufnahme für z. B. einen Eimer oder eine zusätzliche Schale bietet. Dabei durchsetzt der Bügel stets das Schalenelement, das die Hebelkräfte, die über den Bügel übertragen werden, aufnimmt. Hierzu ist vorgesehen, dass sich die Schenkel in ihren Endbereichen auf gegenüberliegenden Seiten an dem Verbindungs- bzw. Schalenelement - nachstehend vereinfacht Schalenelement genannt - abstützen. Somit ist die Gestaltung des Schalenelements gleichfalls als eigenerfinderisch anzusehen.Due to the teachings of the invention, a stepladder with a pivotable and in the stages carrying Holmen hineinschiebbaren bracket is proposed in the region of the shell member a receptacle for z. B. offers a bucket or an additional shell. The bracket always penetrates the shell element, which absorbs the lever forces that are transmitted via the bracket. For this purpose, it is provided that the legs in their end regions on opposite sides of the connection or shell element - hereinafter referred simplified shell element - support. Thus, the design of the shell element is also considered as ownfinderisch.
Bevorzugterweise weist das Schalenelement in Vorderansicht, also in Richtung einer von den ersten Holmen aufgespannten Ebene, eine U-Form mit Seitenschenkeln und Querschenkel auf, wobei die Seitenschenkel innerhalb der Holme verlaufen und mit diesen verbunden wie verschraubt sind. Die Seitenschenkel sollten eine U-Profilgeometrie aufweisen, die an die Innengeometrie der Holme angepasst ist, so dass die Bügelschenkel weitgehend spielfrei in den Holmen angeordnet sind.Preferably, the shell element in front view, ie in the direction of a plane spanned by the first spars level, a U-shape with side legs and transverse legs, wherein the side legs extend within the spars and connected to these are screwed. The side legs should have a U-profile geometry, which is adapted to the internal geometry of the spars, so that the bar arms are arranged largely free of play in the spars.
Die Erfindung würde selbstverständlich dann nicht verlassen werden, wenn die Holme endseitig von den Seitenschenkeln aufgenommen sind.The invention would of course not be abandoned when the spars are received at the ends of the side legs.
Der Querschenkel des Lagerelementes umfasst einen ersten und einen zweiten Abschnitt, die sich jeweils zwischen den Holmen erstrecken. Dabei spannen der erste und der zweite Abschnitt jeweils eine Ebene auf, die versetzt zueinander verlaufen, um einen Absatz zu bilden. Zwischen dem ersten und dem zweiten Abschnitt verläuft eine stegartige Wandung. Im Bereich dieser sind die von den Bügelseitenschenkeln durchsetzten Durchbrechungen vorhanden, die bereichsweise sowohl den ersten Abschnitt als auch die stegartige Wandung durchsetzen.The transverse leg of the bearing element comprises a first and a second portion, each extending between the spars. In this case, the first and the second section each span a plane that is offset from one another to form a step. Between the first and the second section runs a web-like wall. In the area of this are penetrated by the stirrup side legs perforations present in some areas, both the first section and the web-like wall prevail.
Der erste und zweite Abschnitt bilden folglich eine Stufe, so dass bei herausgezogenem Bügel sich dieser zum einen an der Außenseite des ersten Abschnitts und zum andern an der Innenseite des zweiten Abschnitts abstützt. Folglich bilden im Bereich der Durchbrechungen der erste und zweite Abschnitt erste und zweite Abstützungen für die Enden der Bügelseitenschenkel.The first and second sections consequently form a step, so that when the stirrup is pulled out, it is supported on the outside of the first section on the one hand and on the inside of the second section on the other hand. Consequently, they form in the area of the openings the first and second sections include first and second supports for the ends of the stirrup side legs.
Insbesondere ist vorgesehen, dass der in Draufsicht, also in einer in etwa parallel zur Standfläche der Leiter verlaufenden Ebene, eine U-Form aufweisende Querschenkel des Schalenelementes einen ersten und einen zweiten über die Länge des Querschenkels erstreckenden Abschnitt umfasst, dass der erste Abschnitt im Bereich der Seitenschenkel des Schalenelementes verlaufende Seitenbereiche aufweist, dass die Seitenbereiche erste Abstützungen für die Bügelseitenschenkel in der zweiten Stellung des Bügels sind und dass der erste Abschnitt eine äußere Oberfläche aufweist, die versetzt und unterhalb äußerer Oberfläche des zweiten Abschnitts verläuft.In particular, it is provided that the in plan view, ie in a plane extending approximately parallel to the standing surface of the ladder, a U-shape transverse leg of the shell element comprises a first and a second over the length of the transverse leg extending portion that the first portion in the area side portions extending from the side legs of the shell member, the side portions being first supports for the stirrup side legs in the second position of the stirrup and the first portion having an outer surface offset and extending below outer surface of the second portion.
In Weiterbildung der Erfindung ist vorgesehen, dass die stegartige Wandung in seitlich den ersten Abschnitt begrenzende Randwandungen übergeht, die die Oberseite des ersten Abschnitts überragen.In a further development of the invention, it is provided that the web-like wall merges into edge walls delimiting the first section laterally, which project beyond the upper side of the first section.
Beabstandet zu den Randwandungen und der stegartigen Wandung ragen von dem ersten Abschnitt Rastvorsprünge auf, deren lichter Abstand zu den zugewandten Seiten der Randwandungen bzw. der stegartigen Wandung an den Querschnitt der Bügelschenkel angepasst sind, so dass ein Klemmen bzw. Verrasten des Bügels in Nutzstellung bzw. im ungenutzten Zustand möglich ist.Spaced apart from the edge walls and the web-like wall, latching projections protrude from the first section, whose clear distance from the facing sides of the edge walls or the web-like wall is adapted to the cross-section of the bracket legs, so that clamping or latching of the bracket into the use position or latching in the unused state is possible.
Im ungenutzten Zustand (erste Stellung des Bügels) ist erwähntermaßen der Bügel vorzugsweise zwischen der stegartigen Zwischenwandung, die sich zwischen dem ersten und zweiten Abschnitt des Schalenelements erstreckt, und dem bzw. den beabstandet zu diesem verlaufenden Rastvorsprung bzw. Rastvorsprüngen fixiert. Um ein Herausziehen des Bügels und somit Erfassen des Querschenkels zu erleichtern, ist vorzugsweise im Mittenbereich des ersten Abschnitts eine muldenartige Vertiefung vorhanden, die sich zumindest bereichsweise bis in den zweiten Abschnitt hinein erstrecken kann.In the unused state (first position of the bracket), it is mentioned that the bracket is preferably fixed between the web-like intermediate wall which extends between the first and second sections of the shell element and the latching projection or latching projections spaced therefrom. In order to facilitate pulling out of the bracket and thus detecting the transverse leg, a trough-like depression is preferably present in the central region of the first portion, which may extend at least partially into the second section.
Im Nutzzustand (zweite Stellung des Bügels) verläuft dieser in einer quer zu einer von den ersten Holmen und zwischen den ersten Holmen und den zwischen diesen verlaufenden Stufen aufgespannten Ebene, d. h., dass der Bügel in der Nutzstellung eine quer zur Stehleiter verlaufende Ebene aufspannt.In the use state (second position of the bracket), this runs in a direction transverse to one of the first spars and between the first spars and between them Steps spanned level, ie, that the bracket spans in the use position extending transversely to the stepladder level.
Um ein zumindest linienförmiges Anliegen des Endbereichs des Bügels sowohl an der Außenseite des ersten Abschnitts als auch an der Innenseite des zweiten Abschnitts sicherzustellen, ist vorgesehen, dass der jeweilige Bügelseitenschenkel endseitig gekröpft ist und einen ersten Bügelabschnitt und einen versetzt zu diesem parallel verlaufenden zweiten Bügelabschnitt umfasst, wobei in der Nutzstellung (zweiten Stellung) des Bügels der bügelquerschenkelseitig verlaufende Abschnitt als erster Bügelabschnitt auf dem ersten Abschnitt des Lagerelements und endseitiger Abschnitt als zweiter Bügelabschnitt an der Innenseite des zweiten Abschnitts abgestützt ist.In order to ensure at least a line-shaped abutment of the end portion of the bracket both on the outside of the first portion and on the inside of the second portion, is provided that the respective bracket side legs is cranked end and comprises a first bracket portion and offset parallel to this second bracket portion, wherein in the use position (second position) of the bracket of the bow transverse leg side extending portion as the first bracket portion on the first portion of the bearing element and endseitiger Section is supported as a second bracket portion on the inside of the second portion.
Der Endbereich weist die Geometrie einer Stufe auf.The end region has the geometry of a step.
Des Weiteren können in dem zweiten Abschnitt des Schalenelements Durchbrechungen ggf. unterschiedlicher Dimensionierungen vorhanden sein, um Werkzeuge aufzunehmen.Furthermore, in the second section of the shell element perforations may have different dimensions to accommodate tools.
Dadurch, dass insbesondere aus Kunststoff bestehende Kappen zur Querschnittserweiterung auf den Enden der Bügelseitenschenkel befestigt wie geklebt sind, wird ein weiterer Vorteil erzielt. Bei Normstehleitern verringert sich der Abstand der ersten Holme vom unteren zum oberen Ende hin. Infolgedessen liegen die Enden der Bügelseitenschenkel in Abhängigkeit vom Verlauf innerhalb der Holme an den Innenflächen der Holme an. Da der Bügel aus Metall besteht, würde infolgedessen sowohl beim Hineinschieben als auch beim Herausziehen ein störendes kratzendes Geräusch entstehen und gegebenenfalls ein Abrieb auftreten, was bei der Verwendung einer aus Kunststoff bestehenden Kappe folglich vermieden wird.Due to the fact that, in particular, plastic caps for cross-sectional enlargement are fastened to the ends of the stirrup side legs, as glued, a further advantage is achieved. Standard ladders reduce the distance of the first spars from the bottom to the top. As a result, the ends of the stirrup side legs depending on the course within the spars on the inner surfaces of the spars on. As a result, since the bracket is made of metal, both when pushing in and when pulling out a disturbing scratching noise would occur and possibly wear occurs, which is therefore avoided when using a cap made of plastic.
Weitere Einzelheiten, Vorteile und Merkmale der Erfindung ergeben sich nicht nur aus den Ansprüchen, den diesen zu entnehmenden Merkmalen - für sich und/oder in Kombination -, sondern auch aus der nachfolgenden Beschreibung eines der Zeichnung zu entnehmenden bevorzugten Ausführungsbeispiels.Further details, advantages and features of the invention will become apparent not only from the claims, the features to be taken these features - alone and / or in combination - but also from the following description of a drawing to be taken preferred embodiment.

Der
Von den oberen Enden 30, 32 der Steigholme 12, 14 geht ein hohlkörperartiges Verbindungselement wie eine Schale 34 aus, die anhand der
Die Schale 34 umfasst im Schnitt U-förmige Seitenschenkel 36, 38, deren Außengeometrie an die Innengeometrie der Steigholme 12, 14 angepasst ist, um in diese nahezu spielfrei eingesetzt und sodann mit diesen verschraubt zu werden. Insoweit handelt es sich bei der Schale 34 um eine grundsätzlich bekannte Konstruktion.The
Der die Seitenschenkel 36, 38 verbindende Querschenkel 40 besteht aus einem ersten in Draufsicht U-förmigen Abschnitt 42, der stützholmseitig verläuft, und einem zweiten Abschnitt 44. Die Abschnitte 42, 44 weisen in versetzt zueinander verlaufenden Ebenen sich erstreckende obere Außenflächen 46, 48 auf, die bei aufgestellter Leiter 10 in etwa horizontal verlaufen. Zwischen den in versetzt zueinander und vorzugsweise parallel zueinander verlaufenden Ebenen liegenden Außenflächen 46, 48 erstreckt sich eine Zwischenwandung 50, die in Seitenrandabschnitte 52, 54 übergeht, die die Außenfläche 46 des ersten Abschnitts 42 überragen und mit ihren oberen Kanten 56, 58 bündig in die Außenfläche 48 des zweiten Abschnitts 44 übergehen. Die Seitenränder begrenzen des Weiteren außenseitig die Seitenschenkel des U-förmigen ersten Abschnitts 42 der Schale 34.The
Die Außenfläche 46, 48 mit der Zwischenwandung 50 bilden folglich eine Stufe.The
In den Eckbereichen 60, 62 der Außenfläche 46 des ersten Abschnitts 42, die oberhalb des von den Seitenschenkeln 36, 38 umgebenden Raums und somit bei auf den Steigholmen 12, 14 befestigter Schale 34 oberhalb der Hohlräume der Steigholmen 12, 14 verlaufen, sind Durchbrechungen 64, 66 vorhanden, die sich bereichsweise in den ersten Abschnitt 42 und bereichsweise in der Zwischenwandung 50 erstrecken.In the
Die Durchbrechungen 64, 66 werden von Seitenschenkeln 68, 70 eines Bügels 72 durchsetzt. Der Bügel 72 nimmt zwei Stellungen ein, nämlich eine erste Stellung, in der der Bügel 72 nicht genutzt wird, und eine zweite Stellung, die einer Nutzstellung entspricht. In der ersten Stellung erstrecken sich die Seitenschenkel 68, 70 innerhalb der Hohlräume der Steigholme 12, 14. Wird der Bügel 72 genutzt, also in der zweiten Stellung, verlaufen die Seitenschenkel 68, 70 außerhalb der Steigholme 12, 14 und werden über die Schale 34 abgestützt.The
Der Bügel 72, bei dem es sich um einen Drahtbügel handeln kann, weist eine U-Form auf, so dass infolgedessen die Seitenschenkel 68, 70 über einen Querschenkel 74 verbunden sind. Die Enden der Seitenschenkel 68, 70 sind gekröpft, weisen also in versetzt zueinander verlaufenden Ebenen Abschnitte 76, 78 auf, wie sich aus der Seitendarstellung der
In der Nutzstellung liegt der äußere abgewinkelte Abschnitt 76 an der Innenseite des zweiten Abschnitts 44 der Schale 34 an. Der in der Ebene des Bügels 72 verlaufende innere Endabschnitt 78 liegt auf den Querseitenflächen 80, 82 der Außenseite 46 des ersten Abschnitts 42 auf. Somit können die über den Bügel 72 übertragenen Kräfte linienförmig auf die Schale 34 übertragen werden, so dass ein sicheres Fixieren möglich ist, insbesondere dann, wenn von dem Bügel 72 z. B. ein Eimer 80 oder eine Schale 180 entsprechend der
Aus den Darstellungen der
Damit der Querschenkel 74 dann, wenn der Bügel nicht genutzt wird, also die Seitenschenkel 68, 70 in den Steigholmen 12, 14 versenkt sind, erfassbar ist, um die Bügelseitenschenkel 68, 70 aus den Holmen 12, 14 herausziehen zu können, ist im Ausführungsbeispiel sowohl im ersten als auch im zweiten Abschnitt 42, 44 mittig eine muldenartige Vertiefung 90 vorgesehen. Somit ist ein problemloses Ergreifen des Querschenkels 74 möglich.Thus, the
Bevorzugterweise besteht der Bügel 72 aus gebogenem Drahtmaterial und weist einen Durchmesser zwischen 5 und 7 mm, vorzugsweise von 6 mm auf. Die Länge des Bügelquerschenkels beläuft sich bevorzugterweise zwischen 230 mm und 250 mm, ohne dass hierdurch eine Einschränkung der erfindungsgemäßen Lehre erfolgt. Die wirksame Länge des Bügelseitenschenkels 68, 70 also der Bereich, der über die Schale 36 vorsteht, sollte im Bereich zwischen 210 mm bis 230 mm liegen, so dass Schalen und Eimer mit relativ großern Querschnitt einhängbar sind.Preferably, the
Der zweite Abschnitt 44 weist Durchbrechungen oder Öffnungen 92, 94, 96 auf, um z. B. Werkzeuge einstecken zu können. Ferner ragt mittig von dem ersten Abschnitt 42 und in Verlängerung der muldenartigen Vertiefung 90 ein hakenförmiger Vorsprung 98 ab, um z.B. einen Bügel eines Eimers zu halten.The
Des Weiteren gehen von den inneren Ecken des ersten Abschnitts 42 Clips 100, 102 bildende Vorsprünge aus, um z.B. Kabel klemmend aufzunehmen.Furthermore,
Den
Hauptunterschied zwischen den Ausführungsformen der
So sieht das Ausführungsbeispiel der
Ferner gehen von dem vorderen Stirnrand der Schale 180 streifenförmige Haken 184, 186 aus, die z. B. aus Federstahl bestehen und mit dem Querschenkel 174 des Bügels 172 verbunden sein können, wie sich dies aus der
Der Bügel 172 ist entsprechend der erfindungsgemäßen Lehre in den Steigholmen 12, 14 versenkbar, d. h., dass deren Seitenschenkel 68, 70 in die Steigholme 12, 14 hineinschiebbar sind. Insoweit wird auf die Konstruktion und die erfindungsgemäßen Merkmale verwiesen, die im Zusammenhang insbesondere mit der
Der Bügel 172 weicht von dem Bügel 72 dahingehend ab, dass der Querschenkel 174 zu der von den Seitenschenkeln 68, 70 aufgespannten Ebene versetzt verläuft, also über Zwischenschenkel 188, 190 mit den Seitenschenkeln 68, 70 verbunden ist. Die diesbezügliche Konstruktion ist gewählt, damit bei in den Steigholmen 12, 14 versenkten Seitenschenkeln 68, 70 der Querschenkel 174 derart im Bereich der Frontseite des Verbindungs- bzw. Schalenelements 34 verläuft, dass die Haken 184, 186 in etwa in einer Ebene verschwenkt verlaufen können, die vom oberen umlaufenden Rand der Schale 180 beim Fixieren dieser an den Steigholmen 12, 14 aufgespannt ist. Dies ergibt sich sowohl aus der
Durch diese Maßnahmen besteht die Möglichkeit, die Leiter mit der Schale 180 in ihrer Parkposition, also in ihrer an den Steigholmen 12, 14 fixierten Stellung problemlos zu transportieren, ohne dass die Schale 180 sich unkontrolliert von der Leiter 10 lösen kann und ohne dass diese bzw. die Haken 184, 186 zu einer Behinderung führen können.These measures make it possible to easily transport the ladder with the
Wird die Schale 180 genutzt, so wird zunächst der Bügel 172 aus den Steigholmen 12, 14 herausgezogen und in die Stellung verbracht, die der
Sodann wird die Schale 180 um den Querschenkel 174 verschwenkt, wobei die Haken 184, 186 mit dem Querschenkel 174 verbunden bleiben. Die Schale 180 wird sodann von der oberen Seite in den von dem Bügel 172 aufgespannten Rahmen eingesetzt.Then, the
Im Ausführungsbeispiel wird demzufolge die Schale 180 im Uhrzeigersinn von der Parkposition (
