Description

Die Erfindung bezieht sich auf einen Leiterverbinder zum Verbinden von Leitern. Die Erfindung bezieht sich ebenfalls auf eine Anordnung mit einem solchen Leiterverbinder. Leiterkonzepte, bei welchen Leitern verlängert oder verkürzt werden, sind aus der Praxis bereits in verschiedenen Varianten bekannt. Bei der sogenannten Kofferraumleiter können durch viele Gelenke problemlos kürzere Leitersegmente weg- bzw. umgeklappt werden, um die Kofferraumleiter zu verlängern oder zu verkürzen. Wird die Kofferraumleiter zusammen mit einem Leiterlift eingesetzt, dann sind die vielen Gelenke entsprechend stark zu dimensionieren, was den Preis sowie das Gewicht der Kofferraumleiter in die Höhe treibt. Abgesehen davon, können bei der Kofferraumleiter einzelne Leitersegmente nicht weggelassen werden, wenn diese nicht benötigt werden. Dadurch wird die Handhabung der Kofferraumleiter bei niedrigen Höhen schwieriger, als es eine solche niedrige Höhe erfordern würde.The invention relates to a conductor connector for connecting conductors. The invention also relates to an arrangement with such a conductor connector. Ladder concepts in which ladders are lengthened or shortened are already known in practice in various variants. In the case of the so-called boot ladder, shorter joint segments can easily be folded away or folded over by many joints in order to lengthen or shorten the trunk ladder. If the trunk ladder is used together with a ladder lift, then the many joints are correspondingly strong to dimension, which drives up the price and weight of the trunk ladder in the air. Apart from that, in the trunk ladder individual conductor segments can not be omitted if they are not needed. This makes handling the trunk ladder at low altitudes more difficult than would require such a low height.

Als Alternative werden Schiebeleitern eingesetzt. Diese bieten die Möglichkeit, große Höhen zu erreichen. Die Schiebeleiter kann jedoch auch in einzelne Leitersegmente zerlegt werden. Dementsprechend ist für den Transport das Gewicht der Schiebeleiter auf die einzelnen Leitersegmente aufteilbar, und die Gesamtlänge der einzelnen Leitersegmente der Schiebeleiter ist an gängige Transportfahrzeuge angepasst. Weiter weisen gängige Schiebeleitern umgreifende Halterungen auf, durch welche die obenliegenden Leitersegmente zusammengehalten werden. Diese Halterungen würden jedoch mit den Exzenterscheiben eines Leiterlifts kollidieren, welche für eine Stoppvorrichtung im Falle eines Gurtbruchs des Leiterlifts benötigt werden. Diese Exzenterscheiben liegen konstruktionsbedingt auf der schmalen Oberseite des Leiterholms auf. Dementsprechend ist die Verwendung eines Leiterlifts zusammen mit einer Schiebeleiter nicht geeignet.As an alternative, sliding ladders are used. These offer the opportunity to reach high altitudes. However, the extension ladder can also be disassembled into individual conductor segments. Accordingly, the weight of the extension ladder on the individual conductor segments can be divided for transport, and the total length of the individual Conductor segments of the extension ladder is adapted to common transport vehicles. Next, common sliding ladders include encompassing brackets, by which the overhead conductor segments are held together. However, these brackets would collide with the eccentric discs of a ladder lift, which are needed for a stop in the event of a break in the breaker of the conductor lift. These eccentric discs are by design on the narrow top of the ladder stile on. Accordingly, the use of a conductor lift together with an extension ladder is not suitable.

Aus der GB 2 326 665 A ist ein Leiterverbinder gemäß dem Oberbegriff des Anspruchs 1 mit einem ersten Verbindungselement und einem zweiten Verbindungselement bekannt, mit dem zwei Leitern nach Art einer Bockleiter oder einer Schiebeleiter miteinander verbindbar sind.From the GB 2 326 665 A is a conductor connector according to the preamble of claim 1 with a first connection element and a second connection element known, with the two conductors in the manner of a Bockleiter or an extension ladder are connected to one another.

Der Erfindung liegt die Aufgabe zugrunde, einen Leiterverbinder bereitzustellen, mit welchem Leitern schnell und einfach verbunden werden können. Insbesondere soll ein Leiterverbinder bereitgestellt werden, bei welchem die Verwendung eines Leiterlifts nicht beeinträchtigt wird, wofür eine über die gesamte Leiterlänge gleichbleibende, oder annähernd gleichbleibende, Spur- bzw. Leiterbreite notwendig ist. Ebenso ist es eine Aufgabe der Erfindung, eine Anordnung mit einem solchen Leiterverbinder bereitzustellen.The invention has for its object to provide a conductor connector with which conductors can be quickly and easily connected. In particular, a conductor connector is to be provided in which the use of a conductor lift is not impaired, for which a constant over the entire conductor length, or approximately constant, track or conductor width is necessary. It is also an object of the invention to provide an arrangement with such a conductor connector.

Diese Aufgabe wird erfindungsgemäß durch einen Leiterverbinder nach Anspruch 1 gelöst. Ebenso wird eine Anordnung mit einem solchen Leiterverbinder beschrieben. Vorteilhafte Ausgestaltungen der Erfindung sind in den weiteren Ansprüchen beschrieben.This object is achieved by a conductor connector according to claim 1. Likewise, an arrangement will be described with such a conductor connector. Advantageous embodiments of the invention are described in the further claims.

Demgemäß wird ein Leiterverbinder zum Verbinden von mindestens zwei Leitern bereitgestellt. Der Leiterverbinder weist ein erstes Verbindungselement auf, welches an einer Außenseite eines ersten Leiterholms einer ersten Leiter anbringbar ist, wobei das erste Verbindungselement zumindest eine Befestigungseinrichtung zum Verbinden mit dem ersten Leiterholm und zumindest einen Haken zum Halten einer zweiten Leiter an einer ihrer Leitersprossen aufweist. Weiter weist der Leiterverbinder ein zweites Verbindungselement auf, welches an einer Außenseite eines zweiten Leiterholms der ersten Leiter anbringbar ist, wobei das zweite Verbindungselement zumindest eine Befestigungseinrichtung zum Verbinden mit dem zweiten Leiterholm und zumindest einen Haken zum Halten der zweiten Leiter an einer ihrer Leitersprossen aufweist. Dadurch, dass die zweite Leiter mittels der Haken an ihren Leitersprossen gehalten wird, kann verhindert werden, dass die Leiterholme der zweiten Leiter, wie bei einer Schiebeleiter, umgriffen werden. Somit sind auf der Oberseite der Leiterholme der zweiten Leiter keine Halterungen, wie bei einer Schiebeleiter, angeordnet. Damit wird ein Leiterlift, welcher mittels der zweiten Leiter gestützt wird, in seiner Bewegung nicht durch solche Halterungen beeinträchtigt. Der Leiterverbinder kann somit insbesondere bei Anordnungen zum Einsatz kommen, bei denen ein Leiterlift verwendet wird.Accordingly, a conductor connector for connecting at least two conductors is provided. The conductor connector has a first connection element, which can be attached to an outer side of a first ladder stile of a first conductor, wherein the first connection element has at least one fastening device for connecting to the first ladder stile and at least one hook for holding a second conductor to one of its ladder rungs. Furthermore, the conductor connector has a second connecting element, which can be attached to an outer side of a second ladder stile of the first ladder, wherein the second connecting element has at least one Attachment means for connecting to the second ladder stile and at least one hook for holding the second conductor to one of its ladder rungs. The fact that the second conductor is held by means of the hooks on their ladder rungs, it can be prevented that the ladder struts of the second conductor, as in a sliding ladder, are embraced. Thus, no brackets, such as an extension ladder, are arranged on the upper side of the ladder stiles of the second ladder. Thus, a ladder lift, which is supported by the second conductor, is not affected in its movement by such brackets. The conductor connector can thus be used in particular in arrangements in which a conductor lift is used.

Das jeweilige Verbindungselement weist eine weitere Befestigungseinrichtung auf, welche eingerichtet ist, in eine Aussparung einer Leitersprosse einer weiteren Leiter einzurasten, um die weitere Leiter an einem Ende der weiteren Leiter bündig mit einem Ende der ersten Leiter zu verbinden. Vorteilhafterweise können die erste Leiter und die weitere Leiter in Längsrichtung aneinandergereiht verbunden sein. Damit sind die erste Leiter und die weitere Leiter fluchtend, d.h. nicht versetzt zueinander, angeordnet. Die weitere Befestigungseinrichtung kann auch in eine Aussparung der weiteren Leiter einrasten, welche nicht mit einer Aussparung einer Leitersprosse zusammenfällt. Mittels des Leiterverbinders ist es möglich, eine Anordnung aus zwei Leitern schnell und einfach aufzubauen. Dabei kann jede der Leitern beispielsweise als einfache Leiter, Anliegeleiter, Bockleiter, Schiebeleiter oder Kofferraumleiter ausgebildet sein. Durch diese Kombinationen lassen sich Längen der Anordnung von ca. 2,4 m bis ca. 10 m erreichen.The respective connecting element has a further fastening device, which is arranged to engage in a recess of a ladder rung of another ladder to connect the other ladder at one end of the other ladder flush with one end of the first ladder. Advantageously, the first conductor and the further conductors can be connected in a row in the longitudinal direction. Thus, the first conductors and the further conductors are aligned, i. not offset from each other, arranged. The further fastening device can also engage in a recess of the further conductor, which does not coincide with a recess of a ladder rung. By means of the conductor connector, it is possible to build an arrangement of two conductors quickly and easily. In this case, each of the conductors can be designed, for example, as a simple ladder, Anliegeleiter, step ladder, extension ladder or trunk ladder. These combinations can be lengths of the arrangement of about 2.4 m to about 10 m reach.

Wird der Leiterverbinder nicht benötigt, um zwei Leitern zu verbinden, dann können die Verbindungselemente einfach an der Außenseite eines Leiterholms einer Leiter angebracht werden, damit sie nicht verlorengehen. Weiter können die Verbindungselemente einfach entlang des Leiterholms verschoben werden.If the conductor connector is not needed to connect two conductors, then the connection members can be easily mounted on the outside of a ladder stile of a conductor so as not to be lost. Furthermore, the connecting elements can be easily moved along the ladder stile.

In der Praxis werden die Verbindungselemente des Leiterverbinders aus Stabilitätsgründen immer paarweise eingesetzt.In practice, the connecting elements of the conductor connector for stability reasons are always used in pairs.

Ein weiterer Vorteil des Leiterverbinders ist, dass die begehbaren Leitersprossen in ihrer Breite nicht bzw. nur unwesentlich reduziert werden, wodurch auch verlängerte Leitern problemlos von Personen bestiegen werden können.Another advantage of the conductor connector is that the walkable ladder rungs are not or only slightly reduced in their width, so that extended ladders can be easily climbed by people.

Mittels des Konzepts des Leiterverbinders können Leitern bzw. Leiterelemente unter Beibehaltung der Spurbreite und Flexibilität in den Aufbaulängen einfach und schnell verbunden werden.By means of the concept of the conductor connector, conductors or conductor elements can be easily and quickly connected while maintaining the track width and flexibility in the body lengths.

Gemäß einer Ausführungsform des Leiterverbinders sind das erste und das zweite Verbindungselement bezüglich einer Ebene spiegelsymmetrisch zueinander ausgebildet. Dabei verläuft die Ebene insbesondere senkrecht zu den Leitersprossen der ersten Leiter.According to one embodiment of the conductor connector, the first and the second connecting element are formed with respect to a plane mirror-symmetrical to each other. In this case, the plane extends in particular perpendicular to the ladder rungs of the first ladder.

Weiter können das erste und das zweite Verbindungselement parallel und in Längsrichtung versetzt zueinander oder parallel und in Längsrichtung nicht versetzt zueinander angeordnet sein.Furthermore, the first and the second connecting element can be arranged parallel to one another and parallel to one another in the longitudinal direction or parallel to one another and not offset in the longitudinal direction.

Gemäß einer weiteren Ausführungsform des Leiterverbinders weist das erste und das zweite Verbindungselement jeweils ein Basiselement auf, welches mehrere Öffnungen zum Einsparen von Gewicht aufweist. Beispielsweise kann das Basiselement eine gitterartige Struktur, und insbesondere mehrere Längs- und/oder Querstreben, aufweisen, um die gewünschte Struktur mit den Öffnungen zu realisieren. Auf diese Weise kann das Basiselement gleichzeitig stabil und leicht sein.According to a further embodiment of the conductor connector, the first and the second connecting element each have a base element which has a plurality of openings for saving weight. For example, the base element may have a grid-like structure, and in particular a plurality of longitudinal and / or transverse struts, in order to realize the desired structure with the openings. In this way, the base element can be stable and light at the same time.

Weiter kann das Verbindungselement und/oder das Basiselement aus mehreren Teilelementen bestehen, wobei die Teilelemente unterschiedliche Materialien aufweisen. Auf diese Weise ist es möglich, für einzelne Teilelemente besonders leichte Materialien zu verwenden, um so Gewicht zu sparen.Furthermore, the connecting element and / or the base element can consist of a plurality of subelements, the subelements having different materials. In this way, it is possible to use for certain sub-elements particularly lightweight materials, so as to save weight.

Gemäß einer weiteren Ausführungsform des Leiterverbinders sind das erste und das zweite Verbindungselement ausgebildet, den jeweiligen Leiterholm der ersten Leiter zu umgreifen. Insbesondere können das erste und das zweite Verbindungselement formschlüssig in Bezug auf den jeweiligen Leiterholm der ersten Leiter ausgebildet sein.According to a further embodiment of the conductor connector, the first and the second connecting element are formed to engage around the respective ladder stile of the first conductor. In particular, the first and the second connecting element can be formed in a form-fitting manner with respect to the respective ladder stile of the first ladder.

Dabei kann es zu einem Hinterschnitt kommen. Eine Kraftübertragung in Längs- und Querrichtung ist möglich.This can lead to an undercut. A power transmission in the longitudinal and transverse directions is possible.

Ein Leiterholm kann prinzipiell eine beliebige Form aufweisen. Es ist möglich, dass der Leiterholm eine rechteckige Form aufweist, und drei Außenseiten oder vier Außenseiten des jeweiligen Leiterholms mit dem jeweiligen Verbindungselement in Kontakt sind. Wenn das jeweilige Verbindungselement den jeweiligen Leiterholm ganz umgreift, d.h. vier Außenseiten des Leiterholms mit dem Verbindungselement in Kontakt sind, dann kann das Verbindungselement von einem Ende des Leiterholms her auf den Leiterholm aufgeschoben werden. Oder das Verbindungselement wird zuerst an der einen Längskante des Leiterholms, welche es umgreift, aufgeschoben und danach an der anderen Längskante des Leiterholms, welche das Verbindungselement nicht umgreift, aufgesteckt. Wenn das Verbindungselement den Leiterholm dagegen nicht ganz umgreift, d.h. lediglich drei Außenseiten des Leiterholms mit dem Verbindungselement in Kontakt sind, dann kann das Verbindungselement ganz einfach von außen, d.h. in Leitersprossenrichtung, auf den Leiterholm aufgesteckt werden. In diesem Fall wird das Verbindungselement über die Befestigungseinrichtung an dem Leiterholm gehalten.A ladder stile can in principle have any desired shape. It is possible that the ladder stile has a rectangular shape, and three outer sides or four outer sides of the respective ladder stile are in contact with the respective connecting element. If the respective connecting element completely encompasses the respective ladder spar, i. four outer sides of the ladder stile are in contact with the connecting element, then the connecting element can be pushed from one end of the ladder stile ago on the ladder spar. Or the connecting element is first pushed on one longitudinal edge of the ladder stile, which surrounds it, and then attached to the other longitudinal edge of the ladder stile, which does not surround the connecting element. In contrast, if the connecting element does not completely encompass the ladder spar, i. only three outer sides of the ladder stile are in contact with the connecting element, then the connecting element can easily be moved from the outside, i. in ladder rung direction, be attached to the ladder spar. In this case, the connecting element is held on the fastening means on the ladder spar.

Gemäß einer weiteren Ausführungsform des Leiterverbinders sind der zumindest eine Haken des ersten Verbindungselements und der zumindest eine Haken des zweiten Verbindungselements an einer Innenseite des jeweiligen Leiterholms angeordnet. Dementsprechend ist der Haken eines Verbindungselements so mit dem Basiselement des Verbindungselements verbunden, dass sich der Haken zumindest ein Stück weit an der Innenseite des Leiterholms erstreckt. Je kleiner der Abstand zwischen dem zumindest einen Haken des ersten Verbindungselements und dem zumindest einen Haken des zweiten Verbindungselements ist, desto kleiner kann der Abstand der Leiterholme der zweiten Leiter sein, damit die zweite Leiter in die Haken gehängt werden kann.According to a further embodiment of the conductor connector, the at least one hook of the first connecting element and the at least one hook of the second connecting element are arranged on an inner side of the respective ladder stile. Accordingly, the hook of a connecting element is connected to the base element of the connecting element in such a way that the hook extends at least to a certain extent on the inside of the ladder stile. The smaller the distance between the at least one hook of the first connecting element and the at least one hook of the second connecting element, the smaller can be the distance of the ladder struts of the second conductor so that the second conductor can be hung in the hooks.

Vorzugsweise sind die Haken so auf dem Verbindungselement angeordnet, dass beim Einhängen einer Leiter in die Haken die Leitersprossen der ersten und der zweiten Leiter auf gleicher Höhe liegen, um die Leitern sicher besteigen zu können. Mindestens einer der Haken kann über eine Schwer- und/oder Federkraft betätigte Sicherung verfügen, damit eine eingehängte Leiter bei unnatürlicher Krafteinwirkungsrichtung nicht ungewollt aus den Haken fällt.Preferably, the hooks are arranged on the connecting element, that when hooking a ladder into the hook, the ladder rungs of the first and the second ladder are at the same height in order to climb the ladders safely. At least one of the hooks can be operated via a heavy and / or spring-actuated fuse have a suspended ladder in unnatural force direction unintentionally fall out of the hook.

Gemäß einer weiteren Ausführungsform des Leiterverbinders weist die jeweilige zumindest eine Befestigungseinrichtung einen Bolzen auf, welcher geeignet ist, in eine Aussparung an einer Leitersprosse der ersten Leiter oder in eine dafür vorgesehene Aussparung an dem jeweiligen Leiterholm einzurasten, um das jeweilige Verbindungselement an dem jeweiligen Leiterholm zu befestigen. Vorteilhafterweise entsteht durch die Verwendung einer Aussparung einer Leitersprosse an der ersten Leiter kein Mehraufwand für etwaige Aufnahmepunkte, da die Aussparungen der Leitersprossen der ersten Leiter bereits ohnehin vorhanden sind. Es ist jedoch auch möglich, Aussparungen an dem Leiterholm vorzusehen, welche nicht mit einer Leitersprosse zusammenfallen.According to a further embodiment of the conductor connector, the respective at least one fastening device has a bolt which is adapted to engage in a recess on a ladder rung of the first ladder or in a recess provided thereon on the respective ladder rail, to the respective connecting element to the respective ladder rail fasten. Advantageously, by using a recess of a ladder rung on the first conductor no additional effort for any receiving points, since the recesses of the ladder rungs of the first ladder already exist anyway. However, it is also possible to provide recesses on the ladder stile, which do not coincide with a ladder rung.

Weiter kann statt dem Bolzen auch ein anderes geeignetes Element eingesetzt werden.Next, instead of the bolt, another suitable element can be used.

Auch ergibt sich bei dieser Art der Verbindung kein wesentlicher Spalt in Längsrichtung der Leiterholme, was in Verbindung mit einem Leiterlift oder einem Schlitten/Gerät, welches auf der Leiter verfährt, den Abroll- oder Gleitvorgang deutlich erleichtert und einen reibungslosen Betrieb gewährleistet.Also results in this type of connection no significant gap in the longitudinal direction of the ladder struts, which in conjunction with a ladder lift or a slide / device which moves on the ladder, the unwinding or sliding significantly easier and ensures smooth operation.

Dementsprechend kann der Leiterverbinder dazu verwendet werden, Leitern auf zwei verschiedene Arten miteinander zu verbinden.Accordingly, the conductor connector can be used to interconnect conductors in two different ways.

Weiter wird eine Anordnung bereitgestellt. Die Anordnung weist einen Leiterverbinder, wie beschrieben, eine erste Leiter und eine zweite Leiter und/oder eine weitere Leiter auf. Dabei ist die erste Leiter mittels des Leiterverbinders mit der zweiten Leiter und/oder der weiteren Leiter verbunden.Further, an arrangement is provided. The assembly includes a conductor connector as described, a first conductor and a second conductor and / or another conductor. In this case, the first conductor is connected by means of the conductor connector to the second conductor and / or the other conductor.

Durch die Kombination von nur der drei genannten Komponenten der Anordnung lassen sich problemlos Längen von ca. 2,4 m bis ca. 10 m realisieren. Durch die Wahl der Leitern und die Verbindung der Leitern mittels des Leiterverbinders lässt sich die gewünschte Länge einstellen. Mit dem beschriebenen Konzept lassen sich jedoch auch größere bzw. kleinere Längen, als die erwähnten, erreichen.By combining only the three components of the arrangement, lengths of approx. 2.4 m to approx. 10 m can be easily realized. By choosing the conductors and the connection of the conductors by means of the conductor connector can be the set the desired length. With the described concept, however, larger or smaller lengths than those mentioned can be achieved.

Die Anordnung kann in die einzelnen Komponenten zerlegt werden. Dies ermöglicht eine Gewichtsreduzierung beim Tragen, indem die Komponenten einzeln getragen werden können. Es braucht auch nicht immer das komplette Material, d.h. alle Komponenten, für die maximale Länge von bis zu ca. 10 m mitgetragen werden, wenn eine geringere Höhe für eine spezielle Anwendung ausreichend ist.The arrangement can be decomposed into the individual components. This allows a weight reduction when wearing, by the components can be worn individually. It also does not always take the complete material, i. all components, for the maximum length of up to approx. 10 m, if a lower height is sufficient for a special application.

Die Leitern der Anordnung können auch einzeln eingesetzt werden. Dies ermöglicht eine sehr flexible und variable Einsetzung der Komponenten. Zum Beispiel kann eine Bockleiter als normale Bockleiter oder Anlegeleiter eingesetzt werden. Vorteilhafterweise kann die gesamte Montage bzw. Demontage der Anordnung werkzeuglos erfolgen.The conductors of the arrangement can also be used individually. This allows a very flexible and variable installation of the components. For example, a ladder can be used as a normal ladder or ladder. Advantageously, the entire assembly or disassembly of the arrangement can be done without tools.

Gemäß einer Ausführungsform der Anordnung ist die erste Leiter und/oder die zweite Leiter und/oder die weitere Leiter als Bockleiter ausgebildet, welche einen ersten Bockleiterabschnitt, einen zweiten Bockleiterabschnitt und ein Scharnier aufweist. Dabei sind der erste Bockleiterabschnitt und der zweite Bockleiterabschnitt mittels des Scharniers drehbar miteinander verbunden. Vorteilhafterweise ist eine Bockleiter vielfältig einsetzbar.According to one embodiment of the arrangement, the first conductor and / or the second conductor and / or the further conductor is designed as a post conductor, which has a first post-conductor section, a second post-conductor section and a hinge. In this case, the first block conductor section and the second block conductor section are rotatably connected to one another by means of the hinge. Advantageously, a step ladder is versatile.

Gemäß einer weiteren Ausführungsform der Anordnung weist die erste Leiter und/oder die zweite Leiter und/oder die weitere Leiter eine Lift-Schiene für einen Leiterlift auf. Die Anordnung mit dem Leiterverbinder ist insbesondere für einen Leiterlift geeignet, da die Handhabung des Leiterlifts nicht durch den Leiterverbinder beeinträchtigt wird.According to a further embodiment of the arrangement, the first conductor and / or the second conductor and / or the further conductor has a lift rail for a conductor lift. The arrangement with the conductor connector is particularly suitable for a conductor lift, since the handling of the conductor lift is not affected by the conductor connector.

Die für den vorgeschlagenen Leiterverbinder beschriebenen Ausführungsformen und Merkmale gelten für die vorgeschlagene Anordnung entsprechend und umgekehrt.The embodiments and features described for the proposed conductor connector apply to the proposed arrangement accordingly and vice versa.

In den Figuren sind gleiche oder funktionsgleiche Elemente mit denselben Bezugszeichen versehen worden. Ferner sollte beachtet werden, dass die Darstellungen in den Figuren nicht notwendigerweise maßstabsgerecht sind.In the figures, identical or functionally identical elements have been given the same reference numerals. It should also be noted that the illustrations in the figures are not necessarily to scale.

Fig. 1 zeigt eine perspektivische Ansicht einer ersten Leiter 1 mit einem Leiterverbinder 2. Die erste Leiter 1 weist einen ersten Leiterholm 3, einen zweiten Leiterholm 4 und Leitersprossen 5 auf. Dabei verbinden die Leitersprossen 5 den ersten Leiterholm 3 mit dem zweiten Leiterholm 4. Fig. 1 shows a perspective view of a first conductor 1 with a conductor connector 2. The first conductor 1 has a first ladder stile 3, a second ladder stile 4 and ladder rungs 5. In this case, the ladder rungs 5 connect the first ladder stile 3 to the second ladder stile 4.

Der Leiterverbinder 2 weist ein erstes Verbindungselement 6 und ein zweites Verbindungselement 7 auf. Das erste Verbindungselement 6 ist an der Außenseite 8 des ersten Leiterholms 3 angebracht. Dabei weist das in Fig. 1 dargestellte erste Verbindungselement 6 zwei Befestigungseinrichtungen 9 auf, mit welchen das erste Verbindungselement 6 an dem ersten Leiterholm 3 befestigt ist. Weiter weist das erste Verbindungselement 6 zwei Haken 10 auf, mit welchen eine zweite Leiter 11 (siehe Fig. 2) an einer ihrer Leitersprossen 5 gehalten werden kann.The conductor connector 2 has a first connection element 6 and a second connection element 7. The first connection element 6 is on the outside 8 attached to the first ladder stile 3. In this case, the in Fig. 1 illustrated first connecting element 6 has two fastening means 9, with which the first connecting element 6 is attached to the first ladder stile 3. Next, the first connecting element 6 has two hooks 10, with which a second conductor 11 (see Fig. 2 ) can be held on one of its ladder rungs 5.

Das zweite Verbindungselement 7 ist an der Außenseite 12 des zweiten Leiterholms 4 angebracht. Dabei weist das zweite Verbindungselement 7 zwei Befestigungseinrichtungen 9 auf, mit welchen das zweite Verbindungselement 7 an dem zweiten Leiterholm 4 befestigt ist. Weiter zeigt das zweite Verbindungselement 7 zwei Haken 10, mit welchen eine zweite Leiter 11 an einer ihrer Leitersprossen 5 gehalten werden kann.The second connecting element 7 is attached to the outer side 12 of the second ladder stile 4. In this case, the second connecting element 7 has two fastening devices 9, with which the second connecting element 7 is fastened to the second conductor rail 4. Next, the second connecting element 7 shows two hooks 10, with which a second conductor 11 can be held on one of its ladder rungs 5.

Die Anzahl der Befestigungseinrichtungen 9 und der Haken 10 ist nicht auf die in der Fig. 1 gezeigte Anzahl beschränkt. Prinzipiell kann eine beliebige Anzahl von Befestigungseinrichtungen 9 und Haken 10 pro Verbindungselement 6, 7 verwendet werden. Es ist ausreichend wenn ein Verbindungselement 6, 7 lediglich eine Befestigungseinrichtung 9 und/oder einen Haken 10 aufweist. Insbesondere kann ein Verbindungselement 6, 7 ein, zwei, drei, vier, fünf oder sechs Befestigungseinrichtungen 9 und/oder Haken 10 aufweisen.The number of fasteners 9 and the hook 10 is not on in the Fig. 1 number shown limited. In principle, any number of fastening devices 9 and hooks 10 per connecting element 6, 7 can be used. It is sufficient if a connecting element 6, 7 has only one fastening device 9 and / or one hook 10. In particular, a connecting element 6, 7 may have one, two, three, four, five or six fastening devices 9 and / or hooks 10.

Wie Fig. 1 zeigt, sind das erste Verbindungselement 6 und das zweite Verbindungselement 7 spiegelsymmetrisch zueinander ausgebildet. Dabei verläuft die Symmetrieebene parallele zu den Leiterholmen 3, 4 und senkrecht zu den Leitersprossen 5 der ersten Leiter 1.As Fig. 1 shows, the first connecting element 6 and the second connecting element 7 are mirror-symmetrical to each other. In this case, the plane of symmetry runs parallel to the conductor bars 3, 4 and perpendicular to the ladder rungs 5 of the first conductor. 1

Die Verbindungselemente 6, 7 sind so ausgebildet, dass sie den jeweiligen Leiterholm 3, 4 der ersten Leiter 1 umgreifen. Dabei weisen die Verbindungselemente 6, 7 ein im Wesentlichen C-förmiges Profil auf, wobei allerdings die Ränder des Profils an der Öffnung des C-förmigen Profils noch umgebogen sind. Weiter sind die Verbindungselemente 6, 7 formschlüssig mit den Leiterholmen 3, 4 ausgebildet. Insofern können die Verbindungselemente 6, 7 vier Außenseiten der Leiterholme 3, 4 kontaktieren, so dass eine Kraftübertragung zwischen den Verbindungselementen 6, 7 und den Leiterholmen 3, 4 möglich ist.The connecting elements 6, 7 are formed so that they embrace the respective ladder stile 3, 4 of the first conductor 1. In this case, the connecting elements 6, 7 a substantially C-shaped profile, wherein, however, the edges of the profile at the opening of the C-shaped profile are still bent. Next, the connecting elements 6, 7 form-fitting manner with the ladder struts 3, 4 are formed. In this respect, the connecting elements 6, 7 can contact four outer sides of the ladder stiles 3, 4, so that a force transmission between the connecting elements 6, 7 and the ladder struts 3, 4 is possible.

Alternativ können die Ränder des Profils der Verbindungselemente 6, 7 an der Öffnung des C-förmigen Profils nicht umgebogen sein. In diesem Fall werden beispielsweise nur drei Außenseiten der Leiterholme 3, 4 kontaktiert, und die Verbindungselemente 6, 7 können ganz einfach von den Außenseiten 8, 12 her auf die Leiterholme 3, 4 aufgesteckt werden. Damit die Verbindungselemente 6, 7 nicht einfach von den Leiterholmen 3, 4 abfallen können, werden sie mittels der Befestigungseinrichtungen 9 an den Leiterholmen 3, 4 befestigt.Alternatively, the edges of the profile of the connecting elements 6, 7 may not be bent at the opening of the C-shaped profile. In this case, for example, only three outer sides of the ladder stiles 3, 4 contacted, and the connecting elements 6, 7 can be easily attached from the outer sides 8, 12 ago on the ladder stiles 3, 4. So that the connecting elements 6, 7 can not simply fall off the ladder struts 3, 4, they are fastened by means of the fastening means 9 to the ladder struts 3, 4.

Weiter weist der erste Leiterholm 3 eine Innenseite 13 und der zweite Leiterholm 4 eine Innenseite 14 auf. Die Haken 10 des ersten Verbindungselements 6 können an der Innenseite 13 des ersten Leiterholms 3 angeordnet sein. Dabei schauen die Haken 10 nach vorne über den ersten Leiterholm 3 hinaus. Insbesondere können die Haken 10 des ersten Verbindungselements 6 im Wesentlichen parallel zu der Innenseite 13 des ersten Leiterholms 3 verlaufen. Die Haken 10 des zweiten Verbindungselements 7 können an der Innenseite 14 des zweiten Leiterholms 4 angeordnet sein. Dabei schauen die Haken 10 nach vorne über den zweiten Leiterholm 4 hinaus. Insbesondere können die Haken 10 des zweiten Verbindungselements 7 im Wesentlichen parallel zu der Innenseite 14 des zweiten Leiterholms 4 verlaufen. Alternativ wäre auch eine Schrägstellung der Haken 10 denkbar.Furthermore, the first conductor rail 3 has an inner side 13 and the second conductor rail 4 has an inner side 14. The hooks 10 of the first connecting element 6 can be arranged on the inner side 13 of the first ladder stile 3. The hooks 10 look forward beyond the first ladder stile 3. In particular, the hooks 10 of the first connecting element 6 can run substantially parallel to the inner side 13 of the first ladder stile 3. The hooks 10 of the second connecting element 7 may be arranged on the inner side 14 of the second ladder stile 4. The hooks 10 look forward beyond the second ladder stile 4. In particular, the hooks 10 of the second connecting element 7 may extend substantially parallel to the inner side 14 of the second ladder stile 4. Alternatively, an inclination of the hook 10 would be conceivable.

Fig. 2 zeigt eine perspektivische Ansicht einer Anordnung 15 aufweisend eine erste Leiter 1, eine zweite Leiter 11 und einen Leiterverbinder 2. Dabei ist die erste Leiter 1 mittels des Leiterverbinders 2 mit der zweiten Leiter 11 verbunden. Fig. 2 shows a perspective view of an arrangement 15 comprising a first conductor 1, a second conductor 11 and a conductor connector 2. In this case, the first conductor 1 is connected by means of the conductor connector 2 with the second conductor 11.

Die zweite Leiter 11 ist als Bockleiter 16 ausgebildet. Die Bockleiter 16 weist einen ersten Bockleiterabschnitt 17, einen zweiten Bockleiterabschnitt 18 und ein Scharnier 19 auf. Mittels des Scharniers 19 kann der zweite Bockleiterabschnitt 18 gegenüber dem ersten Bockleiterabschnitt 17 gedreht werden.The second conductor 11 is designed as a block conductor 16. The block ladder 16 has a first buck conductor section 17, a second buck conductor section 18 and a hinge 19. By means of the hinge 19, the second block conductor section 18 can be rotated relative to the first block conductor section 17.

Die Bockleiter 16 kann eine Lift-Schiene für einen Leiterlift (in den Figuren nicht gezeigt) aufweisen. Da die Bockleiter 16 in unterschiedlichen Positionen mit der ersten Leiter 1 verbunden werden kann, ist es möglich für den Leiterlift eine niedrige Beladehöhe zu erreichen.The block ladder 16 may include a lift rail for a ladder lift (not shown in the figures). Since the block ladder 16 can be connected in different positions with the first conductor 1, it is possible for the ladder lift to achieve a low loading height.

Fig. 3 zeigt eine perspektivische Ansicht einer Anordnung 15 aufweisend eine erste Leiter 1, eine weitere Leiter 20 und einen Leiterverbinder 2. Sowohl die erste Leiter 1 als auch die weitere Leiter 20 weisen Aussparungen 23 bei den Leitersprossen 5 auf. Mittels des Leiterverbinders 2 ist die weitere Leiter 20 in Längsrichtung der Leitern 1, 20 an der ersten Leiter 1 befestigt. Genauer ist das Ende 21 der ersten Leiter 1 bündig mit dem Ende 22 der weiteren Leiter 20 verbunden. Dazu sind an jedem Verbindungselement 6, 7 des Leiterverbinders 2 jeweils zwei Befestigungseinrichtungen 9 vorgesehen. Dabei greift eine Befestigungseinrichtung 9 in eine Aussparung 23 einer Leitersprosse 5 der ersten Leiter 1 und eine Befestigungseinrichtung 9 in eine Aussparung 23 einer Leitersprosse 5 der weiteren Leiter 20 ein. Fig. 3 shows a perspective view of an arrangement 15 comprising a first conductor 1, a further conductor 20 and a conductor connector 2. Both the first conductor 1 and the other conductors 20 have recesses 23 in the ladder rungs 5. By means of the conductor connector 2, the further conductor 20 is fastened in the longitudinal direction of the conductors 1, 20 to the first conductor 1. More specifically, the end 21 of the first conductor 1 is flush with the end 22 of the other conductor 20. For this purpose, two fastening devices 9 are provided on each connecting element 6, 7 of the conductor connector 2. In this case, a fastening device 9 engages in a recess 23 of a ladder rung 5 of the first conductor 1 and a fastening device 9 in a recess 23 of a ladder rung 5 of the other conductor 20 a.

Mit einem einzigen Leiterverbinder 2 könnten auch drei Leitern 1, 11, 20 miteinander verbunden werden. Weiter können auch Anordnungen realisiert werden, welche mehr als einen Leiterverbinder 2 aufweisen. Beispielsweise könnte eine solche Anordnung zwei Leiterverbinder 2 und drei Leitern aufweisen.With a single conductor connector 2 and three conductors 1, 11, 20 could be connected to each other. Furthermore, arrangements can also be realized which have more than one conductor connector 2. For example, such an arrangement could have two conductor connectors 2 and three conductors.

Fig. 4 zeigt eine perspektivische Ansicht eines Leiterverbinders 2. Zu sehen ist das erste Verbindungselement 6 und das zweite Verbindungselement 7. Jedes Verbindungselement 6, 7 weist zwei Befestigungseinrichtungen 9 und zwei Haken 10 auf. Der Haken 10 des ersten Verbindungselements 6, welcher in Fig. 4 rechts dargestellt ist, weist zusätzlich noch eine Aushebesicherung 24 auf, welche verhindert, dass zwei Leitern 1, 11 einfach getrennt werden können. Fig. 4 shows a perspective view of a conductor connector 2. The first connecting element 6 and the second connecting element 7 can be seen. Each connecting element 6, 7 has two fastening devices 9 and two hooks 10. The hook 10 of the first connecting element 6, which in Fig. 4 shown right, additionally has a lift-off 24, which prevents two conductors 1, 11 can be easily separated.

Die Verbindungselemente 6, 7 des Leiterverbinders 2 sind bevorzugt aus Stahl und/oder Aluminium gefertigt. Dabei weisen die Verbindungselemente 6, 7 jeweils ein Basiselement 25, zumindest eine Befestigungseinrichtung 9 und zumindest einen Haken 10 auf. Wie in Fig. 4 zu sehen ist, enthalten die Basiselemente 25 keine Öffnungen. Alternativ könnten die Basiselemente 25 jedoch auch Öffnungen aufweisen, um Gewicht einzusparen und so den Leiterverbinder 2 leichter zu machen. Zudem sind Varianten denkbar, bei denen das Basiselement aus mehreren Teilelementen unterschiedlichen Materials besteht, um Gewichtsreduzierungen zu erreichen.The connecting elements 6, 7 of the conductor connector 2 are preferably made of steel and / or aluminum. In this case, the connecting elements 6, 7 each have a base element 25, at least one fastening device 9 and at least one hook 10. As in Fig. 4 As can be seen, the base elements 25 contain no openings. Alternatively, however, the base members 25 could also have openings to save weight and thus make the conductor connector 2 lighter. In addition, variants are conceivable in which the base element consists of several sub-elements of different material in order to achieve weight reductions.

Fig. 5 zeigt eine Rückansicht des ersten Verbindungselements 6 des Leiterverbinders 2 aus Fig. 4. Zu sehen sind die Befestigungseinrichtung 9 und der Haken 10 mit der Aushebesicherung 24. Die Leitersprosse 5 sowie der Leiterholm 3 sind lediglich schematisch, mittels gestrichelter Linien, dargestellt. Dabei sind das Profil des ersten Verbindungselements 6 und das Profil des Leiterholms 3 aufeinander abgestimmt. Insbesondere sind das erste Verbindungselement 6 und der Leiterholm 3 formschlüssig miteinander verbunden. Fig. 5 shows a rear view of the first connecting element 6 of the conductor connector 2 from Fig. 4 , You can see the fastening device 9 and the hook 10 with the lift-out 24. The ladder rung 5 and the ladder stile 3 are shown only schematically, by dashed lines. The profile of the first connecting element 6 and the profile of the ladder stile 3 are matched to one another. In particular, the first connecting element 6 and the conductor rail 3 are positively connected with each other.

Die Befestigungseinrichtung 9 weist einen Bozen 26 auf. Der Bolzen 26 ragt, wenn das Verbindungselement 6 mit dem Leiterholm 3 verriegelt ist, in den Hohlraum 27 des Basiselements 25. In diesem Hohlraum 27 befindet sich der Leiterholm 3. Weiter rastet der Bolzen 26, bei verriegeltem Zustand, in eine Aussparung 23 einer Leitersprosse 5 der ersten Leiter 1 ein, um das Verbindungselement 6 mit dem Leiterholm 3 zu verbinden.The fastening device 9 has a Bolzano 26. The bolt 26 protrudes when the connecting element 6 is locked to the ladder stile 3, into the cavity 27 of the base member 25. In this cavity 27 is the ladder stile 3. Next, the bolt 26, when locked, snaps into a recess 23 of a ladder rung 5 of the first conductor 1, to connect the connecting element 6 with the ladder stile 3.

Der Bolzen 26 kann federvorgespannt und selbstarretierend ausgebildet sein. Insbesondere weist der Bolzen 26 ein rundes Profil auf. Jedoch sind auch andere Profilformen denkbar. Dagegen weist die Aussparung 23 der Leitersprosse 5 bevorzugt ein Vierkantprofil auf. Auch hier sind andere Profilformen möglich.The bolt 26 may be spring-biased and self-locking. In particular, the bolt 26 has a round profile. However, other profile shapes are conceivable. In contrast, the recess 23 of the ladder rung 5 preferably has a square profile. Again, other profile shapes are possible.

Die Verbindungselemente 6, 7 können auf den Leiterholmen 3, 4 in Längsrichtung derselben verschoben werden. Dazu müssen die Bolzen 26 zurückgezogen werden. An der gewünschten Stelle rasten die Bolzen 26 dann wieder in die entsprechenden Aussparungen 23 der Leitersprossen 5 ein. Dieses Einrasten kann federvorgespannt automatisch erfolgen. Alternativ kann das Einrasten auch manuell erfolgen.The connecting elements 6, 7 can be moved on the ladder rails 3, 4 in the longitudinal direction thereof. For this purpose, the bolts 26 must be withdrawn. At the desired location, the bolts 26 then engage again in the corresponding recesses 23 of the ladder rungs 5. This latching can be spring-loaded automatically. Alternatively, the locking can also be done manually.

Prinzipiell ist es aus Stabilitätsgründen ausreichend, wenn pro Verbindungselement 6, 7 ein Bolzen 26 mit einem Leiterholm 3, 4 im Eingriff ist.In principle, it is sufficient for reasons of stability if, per connecting element 6, 7, a bolt 26 with a conductor rail 3, 4 is engaged.

Fig. 6 zeigt eine perspektivische Ansicht einer in Fig. 4 dargestellten Befestigungseinrichtung 9. Die Befestigungseinrichtung 9 weist einen Hebel 27 auf, welcher gedreht werden kann, um den Bolzen 26 zu bewegen. Dabei wird die Bewegung des Bolzens 26 durch eine schräge Fläche 28 vorgegeben. Fig. 6 shows a perspective view of an in Fig. 4 The fastening device 9 has a lever 27 which can be rotated to move the pin 26. The movement of the bolt 26 is predetermined by an inclined surface 28.

Fig. 7 zeigt eine perspektivische Ansicht einer alternativen Befestigungseinrichtung 9. Die Befestigungseinrichtung 9 weist einen Hebel 27 auf, welcher nur gedreht werden kann, wenn der Hebel 27 gegen die Kraft einer Feder 29 nach hinten gezogen wird, bis ein Rastelement 30 die Drehung ermöglicht. Auf diese Weise kann verhindert werden, dass der Bolzen 26 von alleine aus der Aussparung 23 einer Leitersprosse 5 springt. Fig. 7 shows a perspective view of an alternative fastening means 9. The fastening means 9 has a lever 27 which can only be rotated when the lever 27 is pulled back against the force of a spring 29 until a locking element 30 allows rotation. In this way it can be prevented that the bolt 26 jumps on its own from the recess 23 of a ladder rung 5.
