Description

Begehbare Vorrichtung auf einer Wasseroberfläche Walk-in device on a water surface
Die vorliegende Erfindung betrifft eine begehbare Vorrichtung auf einer Wasseroberfläche, welche aus einzelnen miteinander verbundenen Stegelementen besteht, wobei zumindest ein Stegelement an eine feste Position ankoppelbar ist.The present invention relates to a walk-in device on a water surface, which consists of individual web elements which are connected to one another, at least one web element being connectable to a fixed position.
Stege an Wasserflächen dienen in der Regel dazu, um Menschen den Zugang bspw. zu einem Schiff zu ermöglichen. Diese Schiffe legen an den Stegen an, so dass der Mensch an einer vorbestimmten Stelle von diesem auf das Schiff gelangen kann, ohne dass er mit dem Wasser in Berührung kommt.Bridges on water surfaces are usually used to give people access to a ship, for example. These ships dock at the piers, so that people can get from there to the ship at a predetermined point without coming into contact with the water.
Stege dienen aber auch dazu, bspw. anderen ein Hinausgehen auf die Wasserfläche zu ermöglichen, ohne dass sie im Wasser stehen. Von Frühling bis Herbst haben diese Stege unterschiedliche Aufgaben, im Winter sind sie dagegen in der Regel nutzlos, da der Schiffsverkehr meist eingestellt ist und bspw. das Angeln nicht erlaubt bzw. nicht möglich ist. Insbesondere in solchen Monaten stören diese Stege. Der vorliegenden Erfindung liegt die Aufgabe zugrunde, eine begehbare Vorrichtung der o.g. Art zu schaffen, welche auf einfache Weise dann entfernt werden kann, wenn Sie nicht mehr benutzt wird. Ein weiterer Teil der Erfindung soll die Aufgabe lösen, eine gute und sichere Verankerung der Stegelemente in Gebrauchslage zu schaffen.Bridges also serve, for example, to enable others to go out onto the water surface without being in the water. From spring to autumn, these jetties have different tasks, but in winter they are usually useless, since shipping traffic is mostly closed and, for example, fishing is not permitted or is not possible. These bridges are particularly annoying in such months. The present invention has for its object to provide a walk-in device of the above type, which can be easily removed when it is no longer used. Another part of the invention is to solve the problem of creating a good and secure anchorage of the web elements in the position of use.
Zur Lösung der Aufgabe führt, dass die Stegelemente durch Scharniere miteinander verbunden sind.To achieve the object, the web elements are connected to one another by hinges.
Die Scharniere ermöglichen es, dass die Stegelemente, wenn sie nicht mehr gebraucht werden, zusammengeklappt werden können und entweder weggenommen und im Winter eingelagert werden oder aber an eine entsprechenden Uferverankerung verbleiben. In jedem Fall ist die Störung durch die begehbare Vorrichtung beseitigt .The hinges make it possible for the web elements to be folded up when they are no longer needed and either to be removed and stored in winter or to remain attached to the bank. In any case, the fault is eliminated by the walk-in device.
Bevorzugt sollen die Stegelemente über die Scharniere so miteinander verbunden sein, dass sie zieharmonikaartig zu- sammenfaltbar sind. Hierdurch nehmen Sie am wenigsten Platz weg.The web elements should preferably be connected to one another via the hinges in such a way that they can be folded up like an accordion. This will take up the least space.
Den Stegelementen sollen zumindest teilweise Schwimmkörper zugeordnet sein. Diese Schwimmkörper haben zum einen die Aufgabe, dass beim Ausbringen der Stegelemente diese auf der Wasseroberfläche schwimmen. Sie haben aber auch die Aufgabe, eine zieharmonikaartig zusammengefaltete begehbare Vorrichtung bzw. die einzelnen Stegelemente dieser Vorrichtung beim Aufladen voneinander zu trennen, so dass die Ste- gelemente fast selbständig auf die Wasseroberfläche auf- gleiten.Floating bodies should at least partially be assigned to the web elements. On the one hand, these floating bodies have the task that when the web elements are deployed, they float on the water surface. However, they also have the task of separating a walk-in device folded like an accordion or the individual web elements of this device from each other during charging, so that the web elements slide onto the water surface almost independently.
Die Schwimmkörper sind im übrigen bevorzugt so ausgestaltet, dass sie aufgeblasen und evakuiert werden können. Hierdurch wird vermieden, dass ein nicht richtig evakuierter Schwimmkörper ein Zusammenlegen der begehbaren Vorrichtung behindert . Im Rahmen der vorliegenden Erfindung soll allerdings auch liegen, dass als Schwimmkörper feste bzw. starre Behälter verwendet werden.The floating bodies are preferably designed in such a way that they can be inflated and evacuated. This prevents an improperly evacuated float from obstructing the walk-in device from collapsing. However, it should also be within the scope of the present invention that solid or rigid containers are used as floating bodies.
Das Ausbringen der Stegelemente, aber auch das Zusammenfalten der begehbaren Vorrichtung kann noch zusätzlich durch mechanische Hilfsmittel, wie bspw. Zugseile od. dgl . unterstützt werden.The spreading out of the web elements, but also the folding of the walk-in device, can additionally be achieved by mechanical aids, such as, for example, pulling ropes or the like. get supported.
Ein zweiter Bereich der vorliegenden Erfindung betrifft die Verankerung der Stegelemente in Gebrauchslage, wofür besonderer Schutz begehrt wird.A second area of the present invention relates to the anchoring of the web elements in the position of use, for which special protection is sought.
In einem bevorzugten Ausführungsbeispiel soll die Veranke- rung so ausgestaltet sein, dass das Stegelement nicht nur PegelSchwankungen der Wasseroberfläche, sondern auch seitliche Bewegungen ausgleichen kann. Hierzu ist erfindungsge- mäss das Stegelement für einen Flaschenzug mit einem Gewicht verbunden. Eine Rolle dieses Flaschenzuges ist frei gelagert und über einen KraftSpeicher mit dem Stegelement verbunden. Bei diesem Kraftspeicher kann es sich um einfache Schraubenfedern handeln, jedoch ist auch an anderen pneumatischen oder hydraulischen Einrichtungen gedacht.In a preferred exemplary embodiment, the anchoring should be designed in such a way that the web element can not only compensate for level fluctuations in the water surface, but also for lateral movements. For this purpose, according to the invention, the web element for a block and tackle is connected to a weight. A roll of this pulley is freely stored and connected to the web element via a force accumulator. This energy accumulator can be a simple coil spring, but other pneumatic or hydraulic devices are also considered.
Bevorzugt sind drei derartige Flaschenzüge im Kreis, 120° voneinander beabstandet angeordnet. Hierdurch werden sämtliche seitliche Bewegungen der begehbaren Vorrichtung aufgefangen. Preferably three such pulleys are arranged in a circle, 120 ° apart. As a result, all lateral movements of the walk-in device are absorbed.

Gemass Figur 1 weist eine begehbare Vorrichtung R eine Mehrzahl von Stegelementen 1.1 bis 1.6 auf. Dabei sind die Stegelemente 1.1 bis 1.6 jeweils über ein Scharnier 2.1 bis 2.4 miteinander gekoppelt.According to FIG. 1, a walk-on device R has a plurality of web elements 1.1 to 1.6. The web elements 1.1 to 1.6 are each coupled to one another via a hinge 2.1 to 2.4.
Das erste Stegelement 1.1 bzw. dessen Scharnier 2.1 liegt an einer Uferverankerung 3 fest. Diese Uferverankerung 3 kann bspw. aus zwei beabstandeten Betonwänden bestehen, wo- bei zwischen beiden hindurch die begehbare Vorrichtung R betreten werden kann.The first web element 1.1 or its hinge 2.1 is fixed to a bank anchorage 3. This bank anchorage 3 can consist, for example, of two spaced concrete walls, wherein the walk-in device R can be entered between the two.
Jedem Stegelement 1.1 bis 1.4 soll ein Schwimmkörper 4.1 bis 4.4 zugeordnet sein. Bevorzugt handelt es sich bei dem Schwimmkörper 4.1 bis 4.4 um eine aufblasbare Hülle, wobei gemass Figur 3 zwei derartige Hüllen 5.1 und 5.2 je Stegelement 1 vorgesehen sind. Mit 6.1 und 6.2 sind Ventilein- richtungen angedeutet, die sowohl ein Aufblasen des Schwimmkörpers, als auch ein Ablassen der Luft gestatten. Die Zufuhr der Luft zu den Schwimmkörpern 4 erfolgt durch Pressluftleitungen 7.1 und 7.2.A floating body 4.1 to 4.4 should be assigned to each web element 1.1 to 1.4. The float 4.1 to 4.4 is preferably an inflatable cover, with two such covers 5.1 and 5.2 being provided per web element 1 according to FIG. With 6.1 and 6.2 valve inputs directions indicated that allow both inflating the float and deflating the air. The air is supplied to the floating bodies 4 through compressed air lines 7.1 and 7.2.
Mindestens ein Stegelement 1.1 bis 1.4 ist gemass Figur l über ein Seil 8.1 bis 8.4 mit einem Gewicht, im vorliegenden Fall mit einem Betonklotz 9.1 bis 9.4 verbunden. Dieser Betonklotz 9.1 bis 9.4 befindet sich auf einem Seegrund 10. Der Festlegung des Seiles 8.1 bis 8.4 dient ein Anker 11, welcher gemass Figur 3 in das Stegelement 1 zwischen den beiden Schwimmkörpern eingelassen ist .At least one web element 1.1 to 1.4 is connected according to FIG. 1 via a rope 8.1 to 8.4 with a weight, in the present case to a concrete block 9.1 to 9.4. This concrete block 9.1 to 9.4 is located on a lake bed 10. The anchor 8.1 serves to fix the rope 8.1 to 8.4, which is embedded in the web element 1 between the two floating bodies according to FIG.
In einer verbesserten Ausführungsform, gemass den Figuren 4 und 5 wird das Seil 8 anderenends des Betonklotzes 9 über eine Umlenkrolle 12 geführt, die in dem Stegelement 1 drehbar gelagert ist. Nach der Umlenkrolle 12 ist ein Flaschenzug 13 vorgesehen, wobei das Seil 8 mehrfach um beab- standete Rollen 14 und 15 geführt ist. Während die Rolle 15 fest mit dem Stegelement 1 verbunden ist, soll zwischen der Rolle 14 und dem Stegelement 1 ein KraftSpeicher 16 vorgesehen sein, der bspw. eine normale vorgespannte Schraubenfeder ist. Hierdurch ist die Lage der Rolle 14 veränderbar.In an improved embodiment, according to FIGS. 4 and 5, the cable 8 is guided at the other end of the concrete block 9 over a deflection roller 12 which is rotatably mounted in the web element 1. A pulley 13 is provided after the deflection roller 12, the cable 8 being guided several times around spaced rollers 14 and 15. While the roller 15 is fixedly connected to the web element 1, a force accumulator 16 should be provided between the roller 14 and the web element 1, which is, for example, a normal prestressed coil spring. As a result, the position of the roller 14 can be changed.
In einem weiterhin bevorzugten Ausführungsbeispiel sollen dem Seil 8 zumindest drei Flaschenzüge 13.1 bis 13.3 zugeordnet sein, die um einen Winkel w von 120° zueinander beabstandet angeordnet sind. Dementsprechend sind auch drei Umlenkrollen 12.1 bis 12.3 vorgesehen, wobei über jede Um- lenkrolle 12.1 bis 12.3 ein eigenes Seil 8.1 bis 8.3 geführt ist. Die Seile 8.1 bis 8.3 können dann zu einem Seil 8 vereinigt werden. Der jeweilige Flaschenzug 13.1 bis 13.3 weist ferner die festliegende Rolle 15.1 bis 15.3 sowie die freie Rolle 14.1 bis 14.3 auf. Jede dieser freien Rollen 14.1 bis 14.3 ist über entsprechende Kraftspeicher 16.1 bis 16.3 mit einem Wandelement 17.1 bis 17.3 des Stegelementes 1 verbunden. Im vorliegenden gezeigten Ausführungsbeispiel sind zwei Schraubenfedern 18.1 und 18.2 beidseits einer Rolle 14 angeordnet und einerseits mit dem Wandelement 17, andererseits mit einem Rahmen 19 verbunden, indem die Rolle 14 drehbar gelagert ist.In a further preferred exemplary embodiment, at least three pulleys 13.1 to 13.3 are to be assigned to the cable 8, which are arranged at an angle w of 120 ° to one another. Accordingly, three deflecting rollers 12.1 to 12.3 are also provided, with a separate rope 8.1 to 8.3 being guided over each deflecting roller 12.1 to 12.3. The ropes 8.1 to 8.3 can then be combined to form a rope 8. The respective pulley 13.1 to 13.3 also has the fixed roller 15.1 to 15.3 and the free roller 14.1 to 14.3. Each of these free rollers 14.1 to 14.3 is connected to a wall element 17.1 to 17.3 of the web element 1 via corresponding energy stores 16.1 to 16.3. In the present embodiment shown are two helical springs 18.1 and 18.2 arranged on both sides of a roller 14 and connected on the one hand to the wall element 17 and on the other hand to a frame 19 by the roller 14 being rotatably mounted.
Die Funktionsweise der vorliegenden Erfindung ist folgende:The operation of the present invention is as follows:
Bspw. im Winter, wenn die begehbare Vorrichtung R nicht gebraucht wird, sollte sich diese in einem zusammengefalteten Zustand, wie er in Figur 2 teilweise angedeutet ist, befinden. Dabei sind die einzelnen Stegelemente 1.1 bis 1.6 senkrecht gestellt, wobei sie jeweils zieharmonikaartig über die entsprechenden Scharniere 2.1 bis 2.6 zusammengefaltet sind. Das erste Stegelement 1.1 schlägt senkrecht stehend an der Uferverankerung 3 an.E.g. in winter, when the walk-in device R is not used, it should be in a folded state, as is partially indicated in FIG. 2. The individual web elements 1.1 to 1.6 are positioned vertically, each being folded like an accordion via the corresponding hinges 2.1 to 2.6. The first web element 1.1 strikes the bank anchorage 3 standing upright.
Sobald die begehbare Vorrichtung R gebraucht wird, was zumindest ab dem Frühjahr der Fall ist, werden die bis dahin entleerten Schwimmkörper 4 aufgeblasen, so dass sich die einzelnen Stegelemente voneinander entfernen. Damit stellen Sie sich auch in einem Winkel zueinander, so dass sie über die Wasserfläche weg von der Uferverankerung 3 gleiten. Falls dies noch unterstützt werden soll, sind entsprechende Seilzüge vorgesehen.As soon as the walkable device R is needed, which is the case at least from spring, the floating bodies 4 which have been emptied up to that point are inflated, so that the individual web elements move away from one another. You also stand at an angle to each other so that they slide over the surface of the water away from the bank anchorage 3. If this should be supported, appropriate cable pulls are provided.
Die aufgeblasenen Schwimmkörper 4 gewährleisten nun, dass die Stegelemente auf einer Wasseroberfläche 20 aufliegen und von dieser getragen werden.The inflated floating bodies 4 now ensure that the web elements rest on a water surface 20 and are carried by it.
Um die begehbare Vorrichtung R zu sichern, ist eine Verankerung, zumindest eines Teils der Stegelemente 1 notwendig. In dem einfachen Ausführungsbeispiel wird nun das Seil 8 an dem Betonklotz 9 festgelegt. Damit ist aber in vielen Fällen eine zu starre Verankerung gegeben, welche die Schwan- kungen der Wasseroberfläche 20 zuwenig ausgleichen kann. Deshalb wird erfindungsgemäss in das Seil 8 ein Flaschenzug 13 eingeschaltet, bei dem zumindest eine Rolle freigelagert ist. Wird nun ein Zug auf das Seil 8 ausgeübt, so wird dieser Zug über die Rolle 14 auf dem Kraftspeicher 16 übertragen, der diesem Zug entgegen wirkt. Hierdurch wird das Stegelement 1 relativ gut fixiert. Eine Verbesserung der Fixierung findet dadurch statt, dass drei Flaschenzüge 13.1 bis 13.3 im Kreis um 120° jeweils zueinander gedreht angeordnet sind. Hierdurch können sämtliche seitliche Schwankungen und unterschiedliche Pegelstände der Wasseroberfläche 20 ausgeglichen werden. In order to secure the walk-in device R, anchoring, at least part of the web elements 1, is necessary. In the simple embodiment, the rope 8 is now fixed to the concrete block 9. In many cases, however, this results in anchoring that is too rigid, which cannot compensate enough for the fluctuations in the water surface 20. Therefore, according to the invention, a pulley 13 is switched into the rope 8, in which at least one roller is exposed is. If a train is now exerted on the cable 8, this train is transmitted via the roller 14 to the energy accumulator 16, which counteracts this train. As a result, the web element 1 is fixed relatively well. An improvement of the fixation takes place in that three pulleys 13.1 to 13.3 are arranged in a circle rotated by 120 ° to each other. In this way, all lateral fluctuations and different water levels of the water surface 20 can be compensated.
