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. 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.
  • 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.
  • a foldable building 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.
  • 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.
  • 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.
  • this building Due to its constructional characteristics, this building can hardly function in a size in which it could serve as an aircraft hangar.
  • wind and snow loads play an increasing role, which must be taken into account.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • FIG. 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.
  • 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.
  • 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.
  • 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.
  • Strut 15 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.
  • 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.
  • 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.
  • 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.
  • the aircraft can now be rolled out of its parking position in a slight curve within the struts 11-15 lying on the ground.
  • the plane is from the rear Rolled up and rolled into the parking position with a slight curve.
  • 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.
  • 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.
  • the strut 11 can be secured on soft ground by means of pegs or on concrete and asphalt spaces with dowels.
  • 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.
  • 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.
  • 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.
  • 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.
  • 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.
  • the spring leg 111 can also be non-positively mounted in the second flange 108.
  • 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.
  • 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.
  • the outermost strut 11 which always remains on the ground, can be provided with a height-adjustable undercarriage.
  • 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.
  • 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.
  • 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.
