be secured in such a way that no hostile hindering the landing of aircraft from their flying machines can land on the landing area, in F i g. 5 to the rest position shown in FIG. 1, the blocking screens are moved from their blocking position shown in FIG. 1 to the position shown in FIG. I len shown, the two lifting cylinders 9 are extended with pressure be-locking position. For this purpose it hits wildly, so that over the pistons If and the KoI-first the upper possibly with the piston benstangenS each locking bar 21 is lifted, rod 8 firmly connected cover plate 18 removed as soon as the locking bar 21 and then the lower space of the lifting cylinder 9 has reached before 65, the two support arms 22 move, a pressure medium container (not shown) that automatically pulls pressure medium outward over the runway surface. This will go beyond the. Then the pressure in the Hubzylin piston 11 and the piston rod 8 of the blocking screen 7 and 9 is released again, so that the entire system

weight of the Spcrrbalkens 21 is carried by the support arms 22 and 23.

In both exemplary embodiments, the process for lifting the lock screen 7 or the Spcrrbalkcn 21 initiated by a release device, not shown. This triggering device has an electronic control and is expediently housed in a central command line so that the entire safety device cannot be triggered by unauthorized persons.

In the context of the invention it is also possible to Place of the spreading device for the in the F i g. 1 to 3 shown execution of the blocking screens 7 another type of spreading is also to be provided. The spreading pan 13 could also be spread hydraulically, for example by means of a second piston rod, which is passed through and with the piston rod 8, which in this case is to be hollow the support ring IS is connected. In certain circumstances but can also be dispensed with entirely on a spreader, since with a suitable design of the lower ends of the spreader arms after the lowering of the Lock screen the arms automatically move into their spread position.

A safeguarding by means of the safety device according to the invention is not only provided for airfields, bridges and roads, but also for example for oil rigs, flight decks of aircraft carriers, etc. in question.

In order to make the triggering of the safety device according to the invention even more difficult by unauthorized persons, the blocking screens could be extended or the safety bar can only be initiated when two locking systems are overridden. The first backup could be through the electronic control of a central control room and the second securing from a spatially distant place.

Claims (12)

Patent claims: 1. Safety device to prevent or . Difficulty landing of aircraft, characterized by locking elements (7, 21) which are sunk into the runway and can be moved out of the runway after actuation of a release device. 2. Safety device according to claim 1, characterized marked !. that the locking elements (7.21) are vertically driven out of the landing or driving cock. . "·. Safety device according to claims 1 and 2, characterized in that the locking elements ( 7, 21) are arranged on hydraulic lifting cylinders (9) which are located in the l.andeb / w carriageway, preferably watertight manholes (12) are housed on their upper side. 4 safety device according to the claims! his 3, characterized in that each Barrier element from a barrier screen (7) with interconnected at their upper ends Spreading arms (13) consists. 5. Sicherheitsvirrichtung according to the claims I to 4. l '.- characterized in that the Sprei / poor (13) via an automatic one Spreading element (14, 15, 16) in connection with one another stand. 6. Safety device according to claims 1 to 5, characterized in that the Spreading element on the inside of the spreading arms (13) and one on the piston rod (8) of the lifting cylinder (9) slidably guided support ring (15) articulated links (14) and a compression spring (16) resting on the support ring (15). 7 safety device according to claims 1 to 3. characterized marked !, that each Blocking element consists of an iron girder or a bar (21) made of reinforced precast concrete. 8. Safety device according to claim 7. characterized in that the carrier or beam (21) has retractable support arms (22, 23) on both of its end faces in the carrier or beam, which can be pulled out of the front ropes from the side by means of a spring or hydraulic cylinder are. 9. Safety device according to one or more of claims I to 8, characterized in that that the barrier screens (7) and barrier beams or beams (21) with an explosive charge (19) are provided. 10. Safety device according to claims 1 to 6, characterized by an am free end of the piston rod (8) attached cover (18). 11. Safety device according to one or more of claims 1 to 10, characterized in that that the blocking screens (7) and blocking beams or bars (21) are provided with a light. 12. Safety device according to claim 11, characterized in that the beacon lights up at predetermined intervals and / or colors. The invention relates to a safety device for prevention or. to aggravate the Landing planes. It is known in conventional warfare. the landing of enemy aircraft or you «. Objects in flight on strategically important ^D rings. like airfield runways, bridges. To prevent roads or the like by means of explosive charges hidden in the ground, but at least make them considerably more difficult. Such explosives placed in the ground s ^; nd, however, very disadvantageous insofar as their use fundamentally leads to the destruction of the secured taxiways or roadways. The object underlying the invention be Therefore stem strategically important objects in a simple and cost-saving way against an undesired one To effectively secure the landing of opposing flying machines without there '? especially in the case of errors, significant damage to the landing b / w. Road results. The solution to this problem is based on iicr use recessed into the runway and retracted after actuation of a triggering device the runway removable locking elements The blocking elements are usually in the runway sunk so that normal air traffic Ivw the usual Lantn · -. Take-off and roll maneuvers undisturbed can be executed. In an emergency, however, the 'Moved locking elements out of their recessed rest position from the runway into their locked position The locking elements can be extended quickly and easily. A significant advantage the extended locking elements then exist. that the elements are already visible, the fringes are clearly recognizable are. This has a great deterrent effect, making the pilots more approaching Machines in contrast to those provided with invisible spicrsgs, so externally unchanged ten runways, be prevented from attempting to land from the outset. The blocking elements are preferably moved vertically out of the landing area. More expedient wise serve to extend the locking elements hydraulic lifting cylinders, which are in the landing area located, are housed at their top preferably watertight closed shafts. The manhole cover can be connected to the free end of the piston rod. The locking elements can be formed from spreading arms connected to one another at their upper ends Lock screens or from a profiled iron girder or a bar made of armored consist of hcnigbeton. In the case of training the Barrier elements ah barrier screens are placed on the spreader arms in connection with each other via an automatically acting spreading device. This can be off on the inside of the spreading arms and on one guided displaceably on the piston rod of the lifting cylinder Support ring articulated links and a compression spring resting on the support ring exist. The safety device according to the invention also offers the possibility of optical security or orientation, if on the locking elements a beacon is attached. Such a lighting system, for example formed by lamps even shows the pilot one without a radio connection
