However, in the sense of the invention, vehicles are also considered to be vehicles and aircraft, insofar as this described or an equivalent mine protection device is technically applicable. In particular, the mine protection device applies to Protection of the interior of armored vehicles or main battle tanks.
- the mine protection device according to the invention is shown as an integrated solution in its basic structure.
- the load side ie the outer and thus the load wall of the vehicle floor 2 consists for example of armored steel, aluminum or fiber composite materials.
- a first layer 3 of hard foam with a density of more than 100 kg / m 3 and a thickness of at least 10 mm is arranged behind it. This hard foam layer 3 dampens the strong dynamic movement of the outer wall 2, which arises due to the blast effect of a mine 5 when it is blown under the vehicle floor, and distributes the pressure load over a large area.
- the rigid foam layer 3 is followed by a structural element plate 6, which in the example shown according to Figure 1 with only two boundary layers 7 and 8 and an intermediate layer 9 truss-like structure, so as to make the structure clear overall.

Based on FIGS. 1 and 2, such is adapted Mine protection shown in Figure 3.
- Such an adapted layer structure can be firmly connected to the vehicle floor 2 be or only be attached on site by simple mechanical fasteners. The same applies to an integrated-adapted solution for the outside one Layer structure. As a result, the vehicle remains in use until it is used before Crisis area easier and more agile.
- the described, not firmly integrated mine protection devices can then be Transport separately from land, water or air vehicles.
- Plastic work can either be achieved by a homogeneous component, for example a thick plate with sufficient dynamic-plastic behavior or by constructive measures.
- the truss structure 6 according to FIG. 1 is shown modified in FIG. 4.
- additional webs 15, in this example perpendicular to the direction of movement the boundary layers 7 and 8, attached This would be the case with dynamic Compressing the structural element plate 6 after a resistance noticeably increase certain path.
- plastically deformable intermediate layers are to be used in the structural element plate 6 Bars 16 (zigzag), such as those made of metal, in particular steel or others Metals with corresponding dynamic-plastic properties or fiber composite materials or elastomers can be used. But also springy Elements can be used as intermediate layers.

- the movement of the vehicle floor even within the layer structure to a standstill come.
- a metal sandwich structure according to FIG. 10 formed from a plurality of structural layers 6 can, for example, be formed from thin aluminum or steel layers.
- Such an embodiment is known under the brand name METAWELL plate from VAW Metawell GmbH.
- a double plate made of aluminum, for example, has a height of eleven millimeters with a weight per unit area of 9.4 kg / m 2 .
- the bending moment in the longitudinal direction, ie measured across the shafts, is 2050 Nmm / mm and transversely, ie with the shafts, 1240 Nmm / mm. These differences in the bending moment can be compensated for by a cross arrangement of the individual layers.
- the permissible compressive force for the double plate is 3.5 N / mm 2 .
- corrugated metal plates made of galvanized steel, which can withstand a pressure load up to three times that of the corresponding aluminum plates.
- any combination of aluminum and steel meta corrugated sheets are also conceivable or other changes to the metal sandwich structure, which are explained below.
- the individual layers 6 of the metal sandwich structure can be designed very variably.
- the undulating intermediate layers 24 each run diametrically offset from one another or be shifted by 180 ° in the longitudinal direction. This means that valleys and Height of the waveform in the case of a multilayer structure directly opposite.
- Another very effective design lies in the cross arrangement of the wave layers. Here is each layer is arranged rotated by 90 °.
- FIG 11 Another design option for the multilayer structure is shown in FIG 11 using the example of the construction with metawell plates according to FIG. 10.
- the Layer structure 6 are laterally spaced, open or closed Hollow profile body 26 used.
- the mixture is hollow Full profile bodies 26 and 25 possible.
- the second intermediate layer is the example the introduction of an open profile body 27 shown.
- the hollow and solid profile bodies 26 and 25 or the open profile body 27 between the respective layers 6 of the multilayer Structure construction also as a load-dependent, deformable structural body be introduced from metal or plastic.
- Substances with certain properties can be filled into the hollow profile body 26.
- other hollow bodies that are deformable on liquids are elastic and / or plastically deformable materials or substances with shock-absorbing properties thought.
- This structure according to Figure 11 thus offers a wide range of interesting Possible uses for a formed from several layers 6 Structure in addition to its primary mine protection.
- Examples include the inclusion of liquid fuels for drive motors, the design for fish intake air or exhaust air from the drive motors and picked out the training as a heat exchanger. This list is not complete and only indicates the versatility of the multi-layer structure Mine protection when used in a vehicle.
- the mine protection device not only consistently formed over a large area, but rather also from individual, area-limited and more manageable, modular mine protection devices can be.
- this partially segmented design there are between the individual mine protection modules connecting and edge webs set, the whole or partly consist of perforated metal sheets or plastics.
- This through Bridges or similar arrangements of separate construction can alternatively in whole or in part
- the single or multi-layer structure 6 concern, but not all or even just a part of the remaining layers.
- Such a mine protection device with a total height of 150 mm can be integrated Solution between the outer bottom plate 2, i.e. the debit side and the inner vehicle floor 4 to be arranged as the end of the crew compartment.
- a 40 mm thick first hard foam layer 3 with a density of 300 to 400 kg / m 3 is arranged behind the outer base plate 2 made of armored steel with a thickness of 8 mm. Above it is a 10 mm thick, dynamically pressure-resistant shatter protection plate 11.1, for example made of composite material or lignostone. This is followed by a first structural layer 6.1 composed of four cross-layered metawell panels (20 mm in total) made of aluminum and a second 10 mm thick rigid foam layer 10.1 with a density of 110 kg / m 3 .
- the subsequent second structural layer 6.2 likewise consists of four cross-glued, individual metawell panels (20 mm), and the third rigid foam panel (10 mm) 10.2 can have the same density as the rigid foam layer 10.1 arranged in front of it or a lower density, for example 50 to 80 kg / m 3 , have.
- the third structural layer (20 mm) 6.3 is identical to the previous one.
- the structure of the three structure layers 6.1, 6.2 and 6.3, which are the same in this example, can of course also be different in the sense of the preceding descriptions.
- the fourth hard foam layer (10 mm) 10.3 serves to decouple the last remainder of the possibly still arriving dynamic movement of the overall structure in connection with the dynamically pressure-resistant layer made of lignostone (10 mm) 11.2 from the inner wall 4 of the vehicle, ie the crew compartment. Therefore, this fourth rigid foam layer 10.3 should have the lowest possible density, for example only 30 to 50 kg / m 3 .
