Definitions

  • One to two-engine light aircraft generally do not have a very high load factor beyond the year. In the winter half-year as well as during bad weather periods they are often on the ground for a long time. Since airplanes are generally expensive and sensitive capital goods, it is desirable to hangar them during standstill phases in order to protect them from the weather.

  • the outermost brackets can be swiveled 90 ° away from the central bracket, which means that the building stands up.
  • the lever system consists of one along the radial part of the middle carrier sliding, spring-loaded carriage, on which a lever is articulated, which is connected at its other end to the outermost carrier.

  • An individual can easily open the weather protection roof using the cable and fold it onto the ground on one side of the aircraft. This opening takes place against the forces of the two torsion springs, so that when the weather protection roof is open, the springs are tensioned and the weather roof is folded up in a semicircle on the floor.

Therefore, there is free space along the pivot axis in front of the parked aircraft 5, which allows the motor-vehicle to safely roll out of the open weather protection roof.

On the one hand, these rubber elements act as spacers so that the wire ropes cannot wear through the planking. On the other hand, due to their static friction with the wire ropes, they help to move them along with them so that the folding is initiated as desired.

Abstract

A weather protective roofing structure for small aircraft comprising a plurality of hemispherical bars which are supported in a rotatable manner around a common axis, which bars are attached to and covered with a plurality of covering material segments forming a hemispherical cover. The hemispherical bars are rotatable around the common axis by means of a tackle apparatus and an electrical winch during assembly of the roofing structure to form an enclosure, and during disassembly and folding of the hemispherical cover. Assembly and disassembly are facilitated by means of two torsion springs provided at the hinge assemblies and attached to the outermost bar.

Description

Ein- bis zweimotorige Leichtflugzeuge weisen über das Jahr hinaus eine in der Regel nicht allzu grosse Auslastung auf. Im Winterhalbjahr wie auch sonst während Schlechtwetterperioden stehen sie oft über längere Zeit am Boden. Da Flugzeuge im allgemeinen teure und empfindliche Investitionsgüter sind, ist es wünschenswert, sie während Standphasen zu hangarieren, um sie vor Witterungseinflüssen zu schützen. Ein mit Schnee bedecktes oder ein mit einer Rauhreif- oder gar Eisschicht überzogenes Flugzeug erfordert überdies viel Vorbereitungsaufwand, um startklar gemacht zu werden. Bei einem hangarierten Flugzeug hingegen entfallen diese zeitraubenden Flugvorbereitungen.One to two-engine light aircraft generally do not have a very high load factor beyond the year. In the winter half-year as well as during bad weather periods they are often on the ground for a long time. Since airplanes are generally expensive and sensitive capital goods, it is desirable to hangar them during standstill phases in order to protect them from the weather. A plane covered with snow or covered with a layer of hoarfrost or even ice requires a lot of preparation to get ready for takeoff. In the case of a hangared aircraft, on the other hand, these time-consuming flight preparations are not necessary.

Ein grosser Teil von Leichtflugzeugen wird aus den genannten Gründen hangariert, das heisst, die Flugzeuge werden in einem festen Gebäude abgestellt. Fehlen geeignete Einstellmöglichkeiten, so wird das Cockpit bestenfalls mit einer speziellen Kapuze überzogen.A large number of light aircraft are hangared for the reasons mentioned, that is, the aircraft are parked in a fixed building. If suitable adjustment options are missing, the cockpit is at best covered with a special hood.

Infolge der Sperrigkeit ihrer Form erfordern Flugzeuge beträchtlich viel Raum, und Hangarplätze sind deshalb entsprechend teuer. Um den zur Verfügung stehenden Platz in einem Hangar bestmöglich auszunützen, werden Leichtflugzeuge im Grundriss "puzzleartig" ineinandergestellt. Hieraus erwachsen jedoch auch Nachteile: Zum Beispiel müssen oft etliche Maschinen umgeparkt oder gar aus dem Hangar ins Freie gestellt werden, bis man den Zugang zu einer bestimmten Maschine hat und sie ins Freie rollen kann. Will die Besatzung für längere Zeit verreisen, muss sie in der Regel alle verstellten Flugzeuge wieder an ihre Plätze zurückstellen. Kommt sie zurück von ihrem Flug, so beginnt die Prozedur von neuem, bis die Flugzeuge alle wieder hangariert sind. Dieses ganze Umparken ist oft eine mühsame und zeitraubende Schwerarbeit. Viersitzige Maschinen können von einer Einzelperson kaum alleine verschoben werden. Hinzu kommt die grosse Gefahr, bei solchen Manövern andere Flugzeuge zu touchieren und Schäden zu verursachen. Nicht zuletzt sind diese leidigen UmparkManöver mit dafür verantwortlich, dass auf die Benutzung eines Flugzeuges verzichtet wird aus Unlust über den unverhältnismässigen Aufwand, bis die Maschine überhaupt startklar ist. Hangariert man aber die Flugzeuge nicht, so sind sie dem Wetter ausgesetzt und erfordern dann wegen Staub, Schnee oder Eis eine aufwendige Vorbereitungsarbeit für einen Flug. In fast allen Motorflug-Clubs sind die geschilderten Probleme bekannt. In einschlägigen Kreisen spricht man oft vom "Hangar-Problem". Auf den meisten Flugplätzen kann man zuwenige Hangarplätze zur Verfügung stellen. Zum Bau eines neuen Hangars fehlt in den meisten Fällen neben dem erforderlichen Kapital auch die Aussicht, überhaupt eine Baubewilligung zu erhalten.Due to the bulkiness of their shape, airplanes require a considerable amount of space, and hangar spaces are therefore correspondingly expensive. In order to make the best possible use of the space available in a hangar, light planes are put together in a "puzzle-like" layout. However, this also results in disadvantages: For example, a number of machines often have to be relocated or even moved from the hangar into the open until you have access to a particular machine and can roll it outside. If the crew wants to travel for a longer period of time, they usually have to put all blocked planes back in their places. If she comes back from her flight, the procedure begins again until the aircraft are all hangared again. All this parking is often a tedious and time-consuming job. Four-seat machines can hardly be moved by an individual alone. There is also the great danger touching other aircraft during such maneuvers and causing damage. Last but not least, these tiresome parking maneuvers are also responsible for the fact that the use of an aircraft is avoided due to reluctance to pay the disproportionate effort until the machine is ready to start. However, if the aircraft are not hung, they are exposed to the weather and then require extensive preparation work for a flight due to dust, snow or ice. The problems described are known in almost all powered flight clubs. In relevant circles one often speaks of the "hangar problem". There is not enough hangar space available on most airfields. In most cases, in addition to the necessary capital, there is no prospect of obtaining a building permit to build a new hangar.

Aus der GB-A-1'367`064 ist ein faltbares Gebäude bekanntgeworden, das geeignet ist, als zusammenfaltbare Garage für Fahrzeuge zu dienen. Es besteht aus einem Rahmen, der mit einer Plane bedeckt ist. Der Rahmen besteht aus einer Anzahl Träger, die je aus einem radialen und einem gebogenen Anteil bestehen. Die Enden der radialen Trägerteile sind um je eine eigene Schwenkachse schwenkbar an zwei Grundelementen angelenkt. Mittels eines federbelasteten Hebelsystems können die äussersten Träger jeweils um 90° vom mittleren Träger weggeschwenkt werden, wodurch sich das Gebäude selber aufrichtet. Das Hebelsystem besteht aus einem längs des radialen Teils des mittleren Trägers gleitenden, federbelasteten Schlitten, an dem ein Hebel angelenkt ist, der mit seinem anderen Ende mit dem äussersten Träger verbunden ist. Weil die Träger nicht alle eine gemeinsame Schwenkachse aufweisen, sondern auf verschiedenen Höhen am Grundelement angelenkt sind, lässt sich das Gebäude auf ebenem Untergrund nicht ganz vollständig schliessen. Es sind auch keine Mittel offenbart, um das Gebäude gegen die Kraft des Hebelsystems automatisch zu öffnen beziehungsweise wieder zusammenzufalten.From GB-A-1'367'064 a foldable building has become known which is suitable to serve as a collapsible garage for vehicles. It consists of a frame covered with a tarpaulin. The frame consists of a number of beams, each consisting of a radial and a curved part. The ends of the radial support parts are each pivotably articulated on two basic elements. Using a spring-loaded lever system, the outermost brackets can be swiveled 90 ° away from the central bracket, which means that the building stands up. The lever system consists of one along the radial part of the middle carrier sliding, spring-loaded carriage, on which a lever is articulated, which is connected at its other end to the outermost carrier. Because the beams do not all have a common swivel axis, but are hinged to the basic element at different heights, the building cannot be completely closed on a level surface. There are also no means disclosed for automatically opening or collapsing the building against the force of the lever system.

Dieses Gebäude kann infolge seiner konstruktionsbedingten Merkmale kaum in einer Grösse funktionieren, in der es als Flugzeughangar dienen könnte. Bei Gebäuden von der Grössenordnung eines Flugzeughangars spielen zum Beispiel Windeinflüsse und Schneelasten eine zunehmende Rolle, welcher Rechnung getragen werden muss. Enthalten die Streben wie bei dem Gebäude nach der GB-A 1'367'064 einen radialen Anteil, an den jeweils eine gebogene Strebe anschliesst, so kann die auf den gebogenen Anteil wirkende Windkraft oder eine auf diesem gebogenen Anteil liegende Schneelast eine grosse axiale Kraft auf diese radialen Streben ausüben, welche bei dieser Konstruktion schwierig aufzunehnmen ist. Ausserdem muss ein Flugzeughangar, der die eingangs beschriebenen Probleme lösen soll, automatisch öffnen- und schliessbar sein, da er infolge seiner Grösse nicht von Hand betätigbar ist.Due to its constructional characteristics, this building can hardly function in a size in which it could serve as an aircraft hangar. For buildings of the size of an aircraft hangar, for example, wind and snow loads play an increasing role, which must be taken into account. If the struts, as in the building according to GB-A 1'367'064, contain a radial portion to which a curved strut is connected, the wind force acting on the curved portion or a snow load lying on this curved portion can exert a large axial force exert on these radial struts, which is difficult to accommodate with this construction. In addition, an aircraft hangar, which is intended to solve the problems described at the beginning, must be able to be opened and closed automatically, since its size means that it cannot be operated by hand.

Die vorliegende Erfindung stellt sich daher zur Aufgabe, eine Wetterschutzbedachung für Leichtflugzeuge zu schaffen, die sämtliche geschilderten Probleme löst, indem sie unter anderem insbesondere

  • ermöglicht, ein zu hangarierendes Flugzeug mittels Motorkraft in die Parkposition in der Wetterschutzbedachung hinein- und hinauszurollen,
  • rasch automatisch öffnen- und schliessbar ist,
  • hohen Windgeschwindigkeiten und grossen Schneelasten standhält, und
  • kostengünstiger als ein konventioneller Hangar zu bauen ist.
The object of the present invention is therefore to create a weather protection roof for light aircraft which solves all of the problems described, in particular by, among other things
  • enables a plane to be hangared to be rolled in and out of the parking position in the weather protection roof using engine power,
  • can be opened and closed quickly and automatically,
  • withstands high wind speeds and large snow loads, and
  • is cheaper than building a conventional hangar.

Diese Aufgabe wird gelöst von einer Wetterschutzbedachung nach dem Oberbegriff des Patentanspruches 1 mit dessen kennzeichnenden Merkmalen.This object is achieved by a weather protection roof according to the preamble of claim 1 with its characterizing features.

Das Flugzeug wird längs auf der Schwenkachse der Streben abgestellt. Diese erfindungsgemässe Konstruktion bringt den Vorteil, dass jedes Flugzeug seinen eigenen Hangar hat und deshalb rasch startklar gemacht werden kann. Es besteht auch keine Gefahr mehr, mit anderen Maschinen bei Parkmanövern zu touchieren. Eine Einzelperson öffnet mit Leichtigkeit über den Seilzug die Wetterschutzbedachung und klappt sie auf der einen Flugzeugseite auf den Boden. Dieses Aufklappen erfolgt gegen die Kräfte der zwei Torsionsfedern, so dass bei der geöffneten Wetterschutzbedachung die Federn gespannt sind und sich die Wetterbedachung halbkreisförmig am Boden aufeinandergefaltet darstellt. In dieser Position wird die nun zuoberst liegende Strebe an der am Boden liegenden mit einem Drahtseil oder einer Kette zusätzlich gesichert. Sodann steht das Flugzeug frei und ist bereit zum Wegrollen. Es braucht weder rückwärts noch vorwärts geschoben zu werden. Der Flugzeugführer kann die Maschine in einer leichten Kurve aus dem Parkplatz herausrollen und ist daher direkt vom Abstellplatz aus bereit zum Rollen. Umgekehrt rollt der Pilot das Flugzeug nach der Rückkehr von der hinteren Seite her in einer leichten Kurve wieder in die halbkreisförmig am Boden liegende, zusammengefaltete Wetterschutzbedachung, um anschliessend kraft der Torsionsfedern die Wetterschutzbedachung über das Flugzeug aufzufalten und zu schliessen.The aircraft is parked lengthways on the swivel axis of the struts. This construction according to the invention has the advantage that each aircraft has its own hangar and can therefore be made ready to go quickly. There is also no longer any danger of touching other machines during parking maneuvers. An individual can easily open the weather protection roof using the cable and fold it onto the ground on one side of the aircraft. This opening takes place against the forces of the two torsion springs, so that when the weather protection roof is open, the springs are tensioned and the weather roof is folded up in a semicircle on the floor. In this position, the strut now on the top is additionally secured to the one on the ground with a wire rope or chain. Then the plane is free and ready to roll away. There is no need to push backwards or forwards. The pilot can roll the machine out of the parking lot in a slight curve and is therefore ready to taxi straight from the parking space. Conversely, the pilot rolls the plane after returning From the back in a slight curve back into the semi-circular, folded weather protection roof lying on the ground, in order to then unfold and close the weather protection roof over the aircraft using the torsion springs.

Figur 1 zeigt eine Gesamtansicht einer erfindungsgemässen Wetterschutzbedachung mit fünf Streben 11-15 im Aufriss. Durch die Streben 11-15 wird das Planenmaterial 2 in vier Segmente 21-24 unterteilt. Jedes dieser Segmente 21-24 ist als ebenes Planenstück zugeschnitten. Die einzelnen Segmente 21-24 sind mit ihren Längsseiten überlappend verschweisst. Dadurch wird eine zugkräftige Verbindung der Segmente 21-24 erreicht. Die Ueberlappung bewirkt zudem eine Verstärkung an der Stelle, wo die Plane 2 auf den Streben 11-15 aufliegt. Die einzelnen Streben 11-15 können aus mehreren, durch Steckrohre verbindbaren Rohrabschnitten bestehen, wobei im Bereich der Steckrohre jeweils Querbolzen durch diese und die Streben steckbar sind. Die Streben 11-15 sind an jeder Endseite an ein Scharnier 3 angelenkt, wodurch sie um eine gemeinsame Schwenkachse je um 180° schwenkbar sind. Sie werden mittels des Seilzuges 4 zugeschwenkt. Das Seil 41 ist dabei über die Zenite 42 der Streben 11-15 geführt. Diese Seillage stellt sich unter Zug zwangsweise ein, da sie dem Grosskreis, also der kürzesten Wegstrecke zwischen den Seilbefestigungen entspricht. Die Strebe 11 bleibt stets am Boden liegen. Das Seil 41 ist an der gegenüberliegenden, äussersten Strebe 15 befestigt. Es wird mittels einer hier nicht dargestellten Elektrowinde aufgewickelt, wobei zuerst alle beweglichen Streben gleichzeitig geschwenkt werden und deshalb das Segment 21 als erstes gefaltet wird. Sobald die Strebe 12 auf der Strebe 11 aufliegt, beginnt die Faltung des Segmentes 22 und so weiter, bis alle Streben 11-15 aufeinander zu liegen kommen und das Planenmaterial 2 zusammengefaltet am Boden liegt. Zum besseren Verständnis ist ein Flugzeug 5 mit gestrichelten Linien eingezeichnet, so wie es bestimmt ist, in die erfindungsgemässe Wetterschutzbedachung hineingestellt zu werden. Es ist dabei von wichtiger Bedeutung, dass das Flugzeug 5 wie dargestellt längs auf der Schwenkachse der Scharniere 3 abgestellt wird. Nur so wird die der Erfindung zugrundeliegende Idee voll genützt, nämlich dass das Flugzeug 5 bei geöffneter beziehungsweise zusammengefalterer Wetterschutzbedachung vorwärts in diese sowohl hinein- wie auch hinausgerollt werden kann.Figure 1 shows an overall view of a weather protection roof according to the invention with five struts 11-15 in elevation. The struts 11-15 divide the tarpaulin material 2 into four segments 21-24. Each of these segments 21-24 is cut as a flat tarpaulin piece. The individual segments 21-24 are welded with their long sides overlapping. This creates a strong connection between segments 21-24. The overlap also causes reinforcement at the point where the tarpaulin 2 rests on the struts 11-15. The individual struts 11-15 can consist of a plurality of pipe sections which can be connected by push-fit tubes, wherein in the area of the push-in tubes cross bolts can be inserted through them and the struts. The struts 11-15 are hinged to a hinge 3 on each end side, as a result of which they can each be pivoted through 180 ° about a common pivot axis. They are swiveled in by means of the cable 4. The rope 41 is guided over the zenith 42 of the struts 11-15. This rope position is inevitable under tension because it is the great circle, i.e. the shortest distance between corresponds to the rope fastenings. The strut 11 always remains on the ground. The rope 41 is attached to the opposite, outermost strut 15. It is wound up by means of an electric winch (not shown here), with all movable struts being pivoted simultaneously first and therefore segment 21 being folded first. As soon as the strut 12 rests on the strut 11, the segment 22 begins to fold and so on until all the struts 11-15 come to lie on one another and the tarpaulin material 2 lies folded on the floor. For better understanding, an aircraft 5 is drawn in with dashed lines, as is intended to be placed in the weather protection roof according to the invention. It is important that the aircraft 5 is parked along the pivot axis of the hinges 3 as shown. This is the only way to make full use of the idea on which the invention is based, namely that the aircraft 5 can be rolled forwards into and out of it with the weather protection roof open or folded together.

Figur 2 zeigt die Wetterschutzbedachung von der Seite. Deutlich erkennbar ist die halbkreisförmige Wölbung der Planensegmente 21-24, die um die darunterliegenden Streben 11-15 gespannt sind. Wiederum ist das hineingestellte Flugzeug 5 dargestellt. Es ist dabei mit seinen Flügelenden 51 auf der Höhe der Strebenzenite 42 abgestellt, wo der zur Verfügung stehende Raum in Querrichtung zum Fluggzeug 5 zur Aufnahme der Tragflächen 51 am grössten ist. Die meisten Flugzeuge sind in ihrer Spannweite grösser als in ihrer Länge. Deshalb bleibt längs der Schwenkachse vor dem abgestellten Flugzeug 5 freier Raum, welcher es erlaubt, gefahrlos mit Motorkraft aus der geöffneten Wetterschutzbedachung herauszurollen.Figure 2 shows the weather protection roof from the side. The semicircular curvature of the tarpaulin segments 21-24, which are stretched around the struts 11-15 underneath, can be clearly seen. The aircraft 5 placed in is again shown. It is parked with its wing ends 51 at the height of the strut zenith 42, where the space available in the transverse direction to the aircraft 5 for receiving the wings 51 is largest. Most of the planes are larger than their length. Therefore, there is free space along the pivot axis in front of the parked aircraft 5, which allows the motor-vehicle to safely roll out of the open weather protection roof.

Die Darstellung in Figur 3 zeigt die zusammengefaltete Wetterschutzbedachung im Grundriss und macht die vorzunehmenden Rollmanöver für das Ein- und Ausparken verständlich. Die Streben 11-15 liegen hier alle aufeinander, während das Planenmaterial 2 daneben zusammengefaltet am Boden liegt. Mit Pfeilen ist der Rollweg für das Flugzeug 5 eingezeichnet. Der Raum zwischen den Scharnieren 3 ist vollständig frei und erlaubt deshalb ein problemloses Manövrieren.The illustration in FIG. 3 shows the folded weather protection roof in the floor plan and makes the roll maneuvers to be undertaken understandable for parking and uncovering. The struts 11-15 are all on top of each other here, while the tarpaulin material 2 is folded next to it on the floor. The taxiway for aircraft 5 is shown with arrows. The space between the hinges 3 is completely free and therefore allows easy maneuvering.

In Figur 4 ist der Vorgang des Auf- beziehungsweise Zuschwenkens der erfindungsgemässen Wetterschutzbedachung durch einen Querschnitt längs der Linie A-A von Figur 2 dargestellt. Weiter sind auch einige Details näher gezeigt. Am Boden liegen bereits die beiden Streben 11 und 12 aufeinander und das dazwischen angeordnete Planensegment 21 liegt zusammengefaltet daneben, innerhalb der halbkreisförmigen Streben 11 und 12. Weil das Gewicht der Streben und des sie verbindenden Planenmaterials auf der rechten Seite der Hochachse nach dem Anheben der ersten Strebe 15 stets höher bleibt als links davon und auf die Strebe 15 im Gegenuhrzeigersinn ein Drehmoment von den Torsionsfedern ausgeübt wird, bleiben die Segmente 23 und 24 immer gespannt, bis die entsprechenden Streben 13 beziehungsweise 14 am Boden aufliegen. Um sicherzustellen, dass die erste Faltung beim Anheben der Strebe 15 in jedem Fall beim Segment 21 erfolgt, kann zwischen der Strebe 11 und 12 ein Gummiseil oder eine Zugfeder gespannt sein. Der Seilzug 4 kann aus einem Textilband bestehen in der Art, wie solche auch als Trag- oder Spanngurten Verwendung finden. Das Textilband 41 braucht bloss über die Zenite der Streben gelegt zu sein. Aus Sicherheitsgründen wird jedoch vorteilhaft ein doppelt geführter Seilzug 4 gewählt. Ein solcher besteht am besten aus zwei parallel über die Zenite der Streben 11-15 geführten Drahtseilen. Dort wo die Drahtseile über die Zenite laufen, werden sie über oder durch Gummielemente geführt, die auf den Zeniten mit den Streben verschraubt sind. Diese Gummielemente wirken einerseits als Distanzhalter, damit die Drahtseile die Beplankung nicht durchscheuern können. Andrerseits helfen sie aufgrund ihrer Haftreibung mit den Drahtseilen mit, dass sie mit jenen mitbewegt werden, sodass die Faltung wie gewünscht eingeleitet wird. Das Aufwickeln des Seilzuges 4 erfolgt vorteilhaft mittels einer elektrischen Seilwinde, welche innerhalb der stets am Boden liegenden Strebe 11 angeordnet ist, wobei die Seile beziehungsweise das Textilband 41 unter dieser Strebe 11 hindurchgeführt sind. Im Falle von Drahtseilen werden diese auf eine Seiltrommel mit eingedrehten Wickelrillen aufgewickelt, damit eine saubere Wicklung sichergestellt ist. Die Seilwinde kann über ein Kabel fernbetätigt werden. Zum Oeffnen der Wetterschutzbedachung kann der Bediener durch eine spezielle Einstiegöffnung 7, welche zum Beispiel durch einen Reissverschluss 7 in einem Segment, das an eine äusserste Strebe anschliesst, geschaffen wird, ins Innere der Bedachung eintreten. Dort betätigt er die Seilwinde, wonach das Zuschwenken der Streben 11-15 unter gleichzeitiger Zusammenfaltung des Planenmaterials 2 am Boden innerhalb der Strebe 11 beginnt. Die Fernbedienung mittels des Kabels erlaubt es dem Bediener, den Vorgang des Zuschwenkens beziehungsweise Oeffnens der Bedachung aus einer beliebigen Position innerhalb der Wetterschutzbedachung zu überwachen und nötigenfalls jederzeit den Schwenkvorgang zu stoppen. Sobald die Wetterschutzbedachung vollständig geöffnet ist, kann die Strebe 15 mittels einer Kette, einem Seil oder einem speziellen Haken an der Strebe 11 gesichert werden. Der Flugzeugführer hat nun freien Zugang zum Flugzeug. Er kann die Vorflugkontrollen durchführen und ist anschliessend direkt aus der Parkposition heraus bereit zum Rollen (ready for taxi). Jegliches Verschieben des Flugzeuges von Hand entfällt, womit auch die Manöver, bei denen die häufigsten Beschädigungen an den Flugzeugen verursacht werden, eliminiert sind. Wie das in Figur 3 angedeutet ist, kann das Flugzeug nun in einer leichten Kurve aus seiner Parkposition innerhalb der am Boden liegenden Streben 11-15 herausgerollt werden.FIG. 4 shows the process of pivoting the weather protection roof according to the invention in and out by a cross section along the line AA in FIG. 2. Some details are also shown in more detail. On the floor, the two struts 11 and 12 are already on top of each other and the tarpaulin segment 21 arranged between them is folded next to it, within the semicircular struts 11 and 12. Because the weight of the struts and the tarpaulin material connecting them is on the right side of the vertical axis after the first one has been lifted Strut 15 always remains higher than the left of it and torque is exerted by the torsion springs on the strut 15 in the counterclockwise direction, the segments 23 and 24 always remain tensioned until the corresponding struts 13 and 14 rest on the ground. To ensure that the first folding occurs when the strut 15 is raised in any case in the segment 21, a rubber rope or a tension spring can be stretched between the strut 11 and 12. The cable 4 can consist of a textile tape in the manner in which they are also used as risers or tension belts. The textile band 41 only needs to be placed over the zenith of the struts. For safety reasons, however, it is advantageous to use a double one Cable 4 selected. It is best to have two wire ropes parallel to the zenith of struts 11-15. Where the wire ropes run over the zenith, they are led over or through rubber elements that are screwed to the struts on the zenith. On the one hand, these rubber elements act as spacers so that the wire ropes cannot wear through the planking. On the other hand, due to their static friction with the wire ropes, they help to move them along with them so that the folding is initiated as desired. The cable 4 is advantageously wound up by means of an electric cable winch which is arranged within the strut 11 which is always on the floor, the ropes or the textile band 41 being passed under this strut 11. In the case of wire ropes, these are wound up on a rope drum with screwed-in winding grooves so that a clean winding is ensured. The cable winch can be operated remotely via a cable. To open the weather protection roof, the operator can enter the roof through a special entry opening 7, which is created, for example, by a zipper 7 in a segment that adjoins an outermost strut enter. There he actuates the cable winch, after which the swiveling of the struts 11-15 begins with the simultaneous folding of the tarpaulin material 2 on the floor within the strut 11. The remote control by means of the cable allows the operator to monitor the process of swiveling or opening the roof from any position within the weather protection roof and, if necessary, to stop the swiveling process at any time. As soon as the weather protection roof is completely open, the strut 15 can be secured to the strut 11 by means of a chain, a rope or a special hook. The pilot now has free access to the aircraft. He can carry out pre-flight checks and is then ready to taxi directly from the parking position. There is no need to move the aircraft by hand, which also eliminates the maneuvers that cause the most frequent damage to the aircraft. As is indicated in FIG. 3, the aircraft can now be rolled out of its parking position in a slight curve within the struts 11-15 lying on the ground.

Für das Einparken des Flugzeuges wird von der hinteren Seite herangerollt und mit einer leichten Kurve in die Abstellposition hineingerollt. Nach dem Entsichern der Streben wird der Seilzug 4 mittels der Winde abgewinkelt, wonach eine Strebe nach der andern unter Mitnahme des dazwischen angeordneten Planenmaterials kraft der Torsionsfedern, welche um die Schwenkachse an den beiden Scharnieren 3 angeordnet sind, zugeschwenkt wird. Im geschlossenen Zustand der Wetterschutzbedachung kann die Strebe 15 zusätzlich mit einem Schloss am Boden gesichert werden. Der Bediener verlässt die Wetterschutzbedachung wieder durch die Einstiegöffnung 7. Um einen sicheren Stand der geschlossenen Bedachung auch bei kräftigen Winden sicherzustellen, kann die Strebe 11 auf weichem Untergrund mittels Heringen oder auf Beton- und Asphaltplätzen mit Dübeln gesichert sein.For parking the plane is from the rear Rolled up and rolled into the parking position with a slight curve. After the struts have been unlocked, the cable 4 is angled by means of the winch, after which one strut is pivoted shut, taking the tarpaulin material arranged therebetween, by means of the torsion springs, which are arranged on the two hinges 3 about the pivot axis. When the weather protection roof is closed, the strut 15 can additionally be secured with a lock on the floor. The operator leaves the weather protection roof again through the entry opening 7. In order to ensure a secure position of the closed roofing even in strong winds, the strut 11 can be secured on soft ground by means of pegs or on concrete and asphalt spaces with dowels.

In Figur 4 sind ausserdem einige Details in perspektivischer Ansicht näher herausgehoben:
Ausschnitt A zeigt, wie das Planenmaterial vorteilhaft an den Streben befestigt ist. Ein Band 8 ist dabei längs dem Ueberlappungsbereich zwischen den zwei Segmenten 23 und 24 aufkaschiert oder aufgeschweisst. Die Längsseiten des Bandes 8 sind je zu einer Lasche 81 ausgebildet. Durch diese Laschen 81 sind Rundstähle 82 gesteckt. Durch spezielle Schlitze im Band 8 sind Riemen 83 geführt, die entweder um das Band 8 unter Umschliessung der Strebe 14 gespannt werden oder aber bloss um die beiden Rundstähle spannbar sind.
In Figure 4, some details are also highlighted in perspective:
Section A shows how the tarpaulin material is advantageously attached to the struts. A band 8 is laminated or welded along the overlap area between the two segments 23 and 24. The long sides of the band 8 are each formed into a tab 81. By these tabs 81 are inserted round steel 82. Straps 83 are guided through special slots in band 8, which are either stretched around band 8 by enclosing strut 14 or can only be tensioned around the two round steels.

Ausschnitt B zeigt, wie das Seil 41 um die Strebe 11 herumgeführt ist. Es bewegt sich um eine speziell angeordnete Rolle 9, von wo das Textilband durch einen schützenden Vierkantstahl 91 geführt ist, an dessen Ende es um eine weitere Rolle 92 auf die Seitenwindentrommel 93 aufgewickelt wird. Die Seilwinde 94 selbst ist über eine Platte 95 fest mit der Strebe 11 verbunden. Mit Vorteil handelt es sich bei der Seilwinde um eine 12-Volt-Winde, wie sie an Abschleppfahrzeugen gebräuchlich sind.Section B shows how the rope 41 is guided around the strut 11. It moves around a specially arranged roller 9, from where the textile band is guided through a protective square steel 91, at the end of which it is wound around the roller winch drum 93 by another roller 92. The cable winch 94 itself is firmly connected to the strut 11 via a plate 95. The winch is advantageously a 12-volt winch, as is common on towing vehicles.

Figur 5 zeigt ein Schwenkscharnier in Ansicht von vorne. An den Streben 11-15 sind endseitig Kappen 10 aufgeschraubt, an denen speziell geformte Flacheisen 101 angeschweisst sind, über welche die Streben an die gemeinsame Schwenkachse 102 angelenkt sind. Am Scharnier anliegend ist ein Flansch 103 über die Schwenkachse geführt angeordnet.Figure 5 shows a swivel hinge in front view. Caps 10 are screwed onto the ends of the struts 11-15, to which specially shaped flat bars 101 are welded, by means of which the struts are articulated to the common pivot axis 102. A flange 103 is arranged on the hinge and is guided over the pivot axis.

Das gleiche Scharnier wird in Figur 6 zusammen mit der Torsionsfeder 104 von oben dargestellt. Die Torsionsfeder 104 ist um die Schwenkachse 102 herum angeordnet, welche durch eine Bauschraube 102 gebildet ist. Der eine Federschenkel 105 der Torsionsfeder 104 kann in das Innere der Strebe 15 hineingesteckt sein. Um die Feder leichter auswechselbar zu machen, kann der Federschenkel 105 auch bloss längs der Strebe 15 kraftschlüssig jedoch lösbar mit dieser von aussen verbunden sein. Eine solche Verbindung kann mittels geeignet stark ausgebildeten Briden erfolgen. Im Inneren der Torsionsfeder befindet sich ein Rohr 106, das zwischen dem Flansch 103 und einem zweiten Flansch 108 mittels der Mutter 109 auf der Schraube 102 eingeklemmt ist. Dieses Rohr 106 gibt der Torsionsfeder als Dorn zusätzlich Halt, während ein zweites, konzentrisch angeordnetes und ebenfalls zwischen den Flanschen 103 und 108 eingeklemmtes Rohr 107 die Feder schützt und sie verschalt. Die beiden Flansche 103 und 108 sind fest mit einer Grundplatte 110 verbunden, auf welcher auch der zweite Federschenkel 111 abgestützt ist. Der Federschenkel 111 kann jedoch auch im zweiten Flansch 108 kraftschlüssig gelagert sein. In dieser Ausführung kann der Flansch 108 zum Beispiel mittels eines speziellen Schraubenschlüssels bezüglich der Schwenkachse 102 verdrehbar sein. Dadurch lässt sich die Federkraft beliebig verstellen.The same hinge is shown in FIG. 6 together with the torsion spring 104 from above. The torsion spring 104 is arranged around the pivot axis 102, which is formed by a building screw 102. The one spring leg 105 of the torsion spring 104 can be inserted into the interior of the strut 15. In order to make the spring easier to replace, the spring leg 105 can also be non-positively but only releasably connected to the strut 15 along the strut 15 from the outside. Such a connection can be made by means of suitably strong brides. Inside the torsion spring there is a tube 106 which is clamped between the flange 103 and a second flange 108 by means of the nut 109 on the screw 102. This tube 106 gives the torsion spring additional support as a mandrel, while a second, concentrically arranged tube 107, which is also clamped between the flanges 103 and 108, protects the spring and connects it. The two flanges 103 and 108 are fixedly connected to a base plate 110 on which the second spring leg 111 is also supported. However, the spring leg 111 can also be non-positively mounted in the second flange 108. In this embodiment, the flange 108 can be, for example, by means of a special Wrench can be rotated with respect to the pivot axis 102. The spring force can be adjusted as required.

Figur 7 zeigt dieselbe Anordnung in perspektivischer Ansicht von hinten. Die Grundplatte 110 ist kraftschlüssig mit der Strebe 11 verbunden. Es ist auch denkbar, dass der Federschenkel 111 zweimal rechtwinklig abgebogen wird und dann in das Innere der Strebe 11 hineingesteckt angeordnet ist.Figure 7 shows the same arrangement in a perspective view from behind. The base plate 110 is non-positively connected to the strut 11. It is also conceivable that the spring leg 111 is bent twice at right angles and is then inserted into the interior of the strut 11.

Um die Mobilität der erfindungsgemässen Wetterschutzbedachung zu erhöhen, kann die eine äusserste Strebe 11, welche stets am Boden liegenbleibt, mit einem höhenverstellbaren Fahrwerk versehen sein. Mit Vorteil besteht ein solches Fahrwerk aus drei Rädern, die an den Endseiten der Strebe 11 an den Grundplatten 110 und in ihrer Mitte an der Platte 95 befestigt sind. Ein endseitig angeordnetes Rad ist dabei ungelenkt, während die andern beiden freigelenkt sind. Bei Bedarf lässt sich dann die zusammengeschwenkte Wetterschutzbedachung innert kurzer Frist mobil machen. Sie kann an ein Fahrzeug angehängt und auf dem Flugplatzareal beliebig verschoben werden.In order to increase the mobility of the weather protection roof according to the invention, the outermost strut 11, which always remains on the ground, can be provided with a height-adjustable undercarriage. Such a chassis advantageously consists of three wheels which are fastened to the base plates 110 on the end sides of the strut 11 and to the plate 95 in the middle thereof. One end wheel is unguided, while the other two are free. If necessary, the swung-together weather protection roof can then be mobilized within a short period of time. It can be attached to a vehicle and moved anywhere on the airfield.

Wird die Wetterschutzbedachung auf Wiesland aufgestellt, so wird es von Vorteil sein, die bedeckte Fläche mit Rasenziegeln zu belegen. Hierdurch wird der Graswuchs nicht verunmöglicht und bei Nässe bleibt ein gefestigter Untergrund erhalten.If the weather protection roof is set up on Wiesland, it will be advantageous to cover the covered area with lawn tiles. This does not make grass growth impossible and a solid subsoil is retained in wet conditions.

Neben den bereits erwähnten Vorteilen der erfindungsgemässen Wetterschutzbedachung sei noch erwähnt, dass ihr Aufstellen keinen zusätzlichen Platz als den üblicherweise bei reihenweise abgestellten Flugzeugen ohnehin beanspruchten erfordert. Dies wird in Figur 3 durch die in einer Reihe nebeneinander aufgestellten Bedachungen angedeutet. Zwischen im Freien abgestellten Flugzeugen wird sowieso ein Sicherheitsabstand vom Flügelende zu Flügelende eingehalten, welcher gerade Platz für die entsprechenden, am Boden liegenden Streben bietet.In addition to the advantages of the weather protection roofing according to the invention already mentioned, it should also be mentioned that its installation does not require any additional space than that which is normally required anyway in the case of aircraft parked in rows. This is indicated in FIG. 3 by the roofs placed side by side in a row. Between airplanes parked outdoors, a safety distance is maintained from the wing end to the wing end, which offers space for the corresponding struts lying on the ground.

Die Bauzeit der vorliegenden Wetterschutzbedachung beziehungsweise deren Aufstellzeit ist im Vergleich zu herkömmlichen Hangars geradezu vernachlässigbar. Innert Stunden ist sie aufgestellt und bezugsbereit. Insgesamt ist der Betrieb einer erfindungsgemässen Wetterschutzbedachung in jeder Hinsicht praktischer und zudem viel kostengünstiger als der eines konventionellen Hangars. Auch die Problematik bezüglich Baubewilligung ist elegant umgangen. Bauten im öffentlich-rechtlichen Sinne sind Gebäude und gebäudeähnliche sowie alle weiteren, künstlich hergestellten und mit dem Boden fest verbundenen Objekte. Die erfindungsgemässe Wetterschutzbedachung wird bloss lösbar mit Heringen oder mittels Karabinerhaken an Dübelschrauben am Boden gesichert, weshalb sie rechtlich keine Baute darstellt. Ist sie zudem mit einem Fahrwerk ausgerüstet, fällt sie rechtlich gar unter den Begriff Fahrzeuge. Eine Baueingabe und Baubewilligung zum Aufstellen der erfindungsgemässen Wetterschutzbedachung ist daher nicht erforderlich. Wenn die Seilwinde mit Niederspannung von zum Beispiel 12 Volt betrieben wird, ist auch das Verlegen von entsprechenden Stromzufuhrkabeln nicht an eine Konzession gebunden. Die Verwendung von Autobatterien steht zudem offen.The construction time of the existing weather protection roof or its installation time is negligible compared to conventional hangars. It is set up and ready for occupancy within hours. Overall, the operation of a weather protection roof according to the invention is more practical in every respect and also a lot cheaper than that of a conventional hangar. The issue of building permits has also been elegantly circumvented. Buildings in the public law sense are buildings and building-like as well as all other, artificially produced objects that are firmly connected to the ground. The weather protection roofing according to the invention is only releasably secured with pegs or by means of snap hooks on dowel screws on the floor, which is why it does not legally represent a building. If it is also equipped with a chassis, it is even legally classified as a vehicle. A building entry and building permit to set up the weather protection roof according to the invention is therefore not necessary. If the cable winch is operated with a low voltage of, for example, 12 volts, the laying of corresponding power supply cables is not tied to a license. The use of car batteries is also open.
