Abstract
Description
Die Erfindung betrifft eine Steigleiter aus Metall, die aus zwei sich gegenseitig stützenden Leiterteilen lösbar zusammensetzbar ist, wobei im oberen Bereich des einen Leiterteils in den Leiterholmen Ausnehmungen zur Aufnahme von Stützmitteln am oberen Ende des anderen Leiterteils vorgesehen sind.The invention relates to a vertical ladder made of metal, which consists of two mutually supporting conductor parts is detachably assembled, wherein in the upper region of the a ladder part in the ladder bars recesses for receiving Support means are provided at the upper end of the other conductor part.
Derartige Steigleitern sind allgemein bekannt. Die beiden Leiterteile können getrennt verwendet werden oder zu einer doppelseitigen Leiter zusammengesetzt werden, wobei die Leiterteile sich gegenseitig stützen. Solche Steigleitern werden heute überwiegend aus Aluminium gefertigt. Bei der Fertigung entstehen an den genannten Ausnehmungen der Leiterholme Grate oder scharfe Kanten. Wird der die Ausnehmungen aufweisende Leiterteil allein benutzt, so umschließen die Finger der die Leiter besteigenden Person in der Regel die Leiterholme. Dabei kann diese Person sich leicht an den Graten oder scharfen Kanten der Ausnehmungen verletzen.Such ladders are generally known. The two ladder parts can be used separately or put together to form a double-sided ladder with the ladder parts supporting each other. Such ladders will be today mainly made of aluminum. During production, the mentioned recesses of the ladder stiles burrs or sharp edges. Will the used the recessed conductor part alone, so enclose the fingers the person climbing the ladder is usually the ladder stile. This can Person easily get on the ridges or sharp edges of the recesses hurt.
Die Aufgabe der Erfindung besteht daher darin, den Benutzer einer Steigleiter der eingangs genannten Art vor den geschilderten Verletzungen zu schützen. The object of the invention is therefore the user of a vertical ladder Protect the type mentioned above from the injuries described.
Diese Aufgabe wird durch die Merkmale des Anspruches 1 gelöst.This object is solved by the features of
Wenn der die Ausnehmungen aufweisende Leiterteil allein benutzt wird, decken die Kappen die Ausnehmungen ab. Die Finger des Benutzers umgreifen nun die zweckmäßigerweise mit abgerundeten Kanten versehene Kappe und können nicht mehr verletzt werden. Zur Aufnahme der Stützmittel des anderen Leiterteils in den Ausnehmungen werden die Kappen entfernt, wobei diese aber am Leiterteil gehalten werden, so daß sie nicht verlorengehen können.If the ladder part having the recesses is used alone, the cover Cut the recesses. The user's fingers now grasp the expediently provided with rounded edges and can not get hurt more. To accommodate the support means of the other conductor part in the The caps are removed from recesses, but these are on the ladder part be held so that they cannot get lost.
Vorteilhaft ist es, die Kappen in den Ausnehmungen im Preßsitz anzuordnen und sie mit einem an der Leiter befestigbaren Band zu versehen, an dem sie beim Herausnehmen aus den Ausnehmungen an der Leiter hängenbleiben.It is advantageous to arrange the caps in the recesses in the press fit and to provide them with a tape that can be attached to the ladder Take out of the recesses on the ladder.
Um die Handhabung der Kappen zu verbessern, ist gemäß einer weiteren Ausbildung der Erfindung vorgesehen, die Kappen an den Leiterholmen verschiebbar zu befestigen. Eine Ausführung kann derart ausgebildet sein, daß die Kappen an den Leiterholmen quer verschiebbar angeordnet sind, wobei die Kappen sich also in Einklinkrichtung der Stützmittel des anderen Leiterteils bewegen und beispielsweise durch Federkraft beim Ausklinken des anderen Leiterteils in die die Ausnehmungen abdeckende Lage zurückgebracht werden.To improve the handling of the caps, according to another Training of the invention provided the caps on the ladder stiles slidably fasten. An embodiment can be designed such that the Caps are arranged on the ladder bars so that they can be moved transversely, the caps thus move in the latching direction of the support means of the other conductor part and for example by spring force when the other conductor part is notched into the Position covering recesses are brought back.
Gemäß einer weiteren Ausbildung der Erfindung wird aber eine Ausführung bevorzugt, bei der die Kappe an den Leiterholmen längsverschiebbar angeordnet sind. Die Schwerkraft der Kappe kann dann dafür ausgenutzt werden, die Kappe in die Abdecklage zu bringen.According to a further embodiment of the invention, however, an embodiment preferred, in which the cap is arranged to be longitudinally displaceable on the ladder stiles are. The cap's gravity can then be exploited to bring in the cover layer.
Weitere vorteilhafte Merkmale der Erfindung sind in Unteransprüchen niedergelegt.Further advantageous features of the invention are set out in the subclaims.

In Fig. 1 ist der obere Teil eines Steigleiterholms 1 mit einem Leitersprossenteil 2
und einer am oberen Leiterende angeordneten Gummikappe 3 in Draufsicht
dargestellt. Der andere Leiterholm der Steigleiter ist nicht dargestellt und
entsprechend ausgebildet. Der Leiterholm 1 ist mit einer Ausnehmung 4 versehen,
deren längliche nach innen zu sich verjüngende Form aus Fig. 2 zu erkennen ist.
Die Ausnehmung 4 dient zur Aufnahme von nicht dargestellten Stützmitteln des
anderen Leiterteils einer
doppelseitigen Steigleiter. Diese Stützmittel können eine runde Stange, die am
Ende des anderen Leiterteils zwischen deren Holme befestigt ist, oder runde, an
den Holmenden des anderen Leiterteils befestigte Achsstümpfe sein. Nach dem
Einführen solcher Stützmittel in die Ausnehmung 4 wird der andere Leiterteil am
Leiterholm 1 in nicht dargestellter Weise gesichert.In Fig. 1 is the upper part of a
Über der Ausnehmung 4 ist eine Kappe 5 in einer diese Ausnehmung freigebenden
Lage gezeigt. Wie aus den Figuren 1 und 2 zu entnehmen ist, ist die aus
Kunststoff oder Metall bestehende Kappe 5 im Querschnitt U-förmig mit zwei
Seitenschenkeln 6, 7 und einem diese Seitenschenkel verbindenden
Zwischenstück 8 und an die Holmform formschlüssig angepaßt. Die
Seitenschenkel 6, 7 sind derart bemessen, daß die Ausnehmung 4 abgedeckt
werden kann. Das Zwischenstück 8 weist ein in Leiterlängsrichtung verlaufendes
Langloch 9 auf, durch das ein am Leiterholm 1 über der Ausnehmung 4 befestigter
Bolzen 10 geführt ist, der die Kappe 5 mit seinem Bolzenkopf hält.Above the
Das Zwischenstück 8 ist ferner am oberen Ende und am unteren Ende mit Griffen
11, 12 in Form von Wülsten versehen. Weiterhin trägt das Zwischenstück 8 zwei
Pfeildarstellungen 13, 14, die insbesondere durch das Material des
Zwischenstücks 8 gebildet sind und die Richtungen angeben, in denen die Kappe
5 verschiebbar iat. Aus Fig. 2 ist erkennbar, daß diese Pfeildarstellungen erhaben
ausgebildet sind. Die Kanten der Kappe sind abgerundet. Vorzugsweise ist die
Kappe ein Kunststoffspritzteil.The
In den Figuren 3 und 4 des Ausführungsbeispiels ist die Kappe 5 nach unten
verschoben, so daß sie die Ausnehmung 4 abdeckt. Diese Verschiebung kann
nach Entfernen des anderen Leiterteils vorzugsweise durch das Eigengewicht der
Kappe 5 erfolgen. Es kann jedoch auch ein Reibsitz der Kappe 5 gewählt werden,
so daß diese von Hand in die Abdecklage verschoben werden muß. Das Öffnen
der Ausnehmung 4 kann durch Verschieben der Kappe 5 nach oben mittels des
anderen Leiterteils erfolgen, wobei dieser Leiterteil am unteren Griff 12 ansetzt.
Die Abdeckung der Ausnehmung 4 wird damit mit einfachen Mitteln
vorgenommen.In Figures 3 and 4 of the embodiment, the
Wird der Leiterteil mit dem Holm 1 alleine benutzt, so ist die Ausnehmung 4
abgedeckt. Der Benutzer kann sich an den Kanten dieser Ausnehmung nicht mehr
