Abstract

The container has multi-layer walls (14) to protect the interior against penetration. Each wall has at least a light metal honeycomb core (26,36), flanked by sandwich covering layers (28,32,38,42). The gap between the covering layers is greater than the penetration depth of manual power tool with a rotating cutting disk or circular saw. At least one covering layer is of aramide fibers in three layers, with a thermoplastic core (30,40) between the aramid fiber sheets. The layer of aramid fibers is coated with rubber on at least one side.

Description

The invention relates to a transport container with its interior before access protective walls.

Transport containers are used, for example, as safety containers for dangerous goods, Valuables or other items worth protecting. For such Use it is desirable if the container is the good to be transported protects as securely as possible from outside access. Especially with particularly valuable Transport goods must be expected to have massive access is tried using complex tools. For example, unauthorized removal of the transport goods mechanical or thermal, cutting or cutting tools or explosives.

A test criterion for such transport containers is whether they have an attack with commercially available, portable mechanical tools for at least 30 minutes can resist; an attack is then considered successful in such an examination, if with the mentioned tool an opening in the container with a clear Width of 300 x 300 mm was generated within the 30 minutes.

The aim of the present invention is to provide a transport container which an attack in the above sense with commercially available, portable mechanical Resist the tool as long as possible over the required minimum period can.

According to the invention, this goal is achieved with a transport container with its interior access-protecting, multi-layer walls are achieved, each at least consist of a honeycomb core with cover layers on both sides is provided and at least on one side a layer containing aramid fibers has, wherein the distance between the outer layers is greater than that maximum depth of penetration of a portable, hand-held tool with a rotating release agent such as a cutting disc, a circular saw blade or the like. like.

The honeycomb core, which is covered on both sides with cover layers, provides a sandwich panel represents, the honeycomb core is between two cover layers and with these is connected for example by gluing. The honeycombs of the honeycomb core are included preferably aligned so that their longitudinal direction is transverse to the cover layers runs.

It has been found that such a structure of the walls of a transport container not only offers extraordinarily good protection against external access, but also manages with relatively little mass, so that a Containers with such walls need not be excessively heavy. This significantly improves the transport properties of the container.

A special feature of the container is that its walls are extraordinary can absorb a lot of energy and in this way the additional Offer the advantage that they not only transport goods before unauthorized removal protect, but also from damage, for example by bombardment with Handguns or long weapons as well as mechanical effects as a result of Accident.

Despite the light structure of its walls, the transport container is mechanical Tool extremely difficult to open: an attack with itself and forth moving tool such as jigsaws or chisels fails because the Swing the walls of the container and / or the tool jams and vibrates itself, so that the energy introduced by the tool to the is largely absorbed without damaging the walls of the transport container to take. Because of their shock absorbing properties, the walls resist of the transport container also particularly well deforming attacks Help, for example, with a jackhammer.

To cut the container walls using cutting discs or circular saws to counteract, should cover the honeycomb core of the walls on both sides Cover layers have a distance from each other that is greater than the maximum Penetration depth of such tools. On the one hand, this is based on the knowledge that the rotating release means of such portable, hand-held tools can hardly exceed a certain maximum diameter because otherwise the forces to be used to operate the tools become too great, to be able to hold the tool with your hands. Another finding consists in the use of portable tools other than hand-held Due to their lack of flexibility, they are not regularly attacked Transport containers come into question. The maximum depth of penetration of tools with a rotating separating agent such as a cutting disc or a circular saw blade is in any case smaller than half the diameter of the release agent. The largest diameter of cutting discs is usually manually operated Tools today 230 mm. The maximum depth of penetration of these tools is 75 mm.

If the top layers of the walls of the transport container a greater distance than the maximum penetration depth of the tools mentioned, can with such tools, only one of the cover layers is cut through. Around to also cut through the second cover layer would first have to cut through the first cover layer and the honeycomb material present between the two cover layers be removed. This takes a lot of time due to the toughness of the material Claim. This leads to the surprising result that relatively easy built walls of the transport container an extraordinarily good protection against provide external access.

The walls of the transport container face at least on one side of the honeycomb core a layer containing aramid fibers. Such a layer can be Cutting very poorly due to the aramid fibers is impact and shock resistant. At the Cutting the aramid fibers leads to strong fiber pulling which Cutting hindered. An attack with a cutting torch or explosives leads to a strong, poorly erasable glow of the aramid fiber laminate and impedes hence further attacks.

The layer containing aramid fibers is preferably at least three layers and has a thermoplastic between two layers of aramid fiber Location on. The purpose of the thermoplastic is, for example, cutting discs at Closing, hindering an attack by smoke and in particular by reflowing the closure of a cut behind one Effect cutting tool. Suitable thermoplastics are polycarbonate or Polyethylene.

It is furthermore advantageous if the aramid layer has at least one side on the outside Rubber coated.

Outside of the - based on the transport container - outer aramid fiber-containing Layer is preferably a fourth layer containing a thermoplastic. Such an additional thermoplastic layer has more penetrating properties Body a sliding effect with the result that the energy-absorbing effect deer subsequent aramid fiber-containing layer comes into full effect.

A preferred embodiment variant of a transport container with multilayer walls is characterized in that the walls comprise at least the following layers from the outside in:

A first layer, which is formed by a honeycomb core provided on both sides with cover layers,

a second layer containing aramid fibers

an intermediate layer filled with gas as the third layer,

a fourth layer which is formed by a honeycomb core provided on both sides with cover layers, and

a fifth layer containing aramid fibers.

The advantages of the first and second layers as well as the corresponding ones fourth and fifth layers have already been explained. The third layer with gas filled intermediate layer, serves as protection against lightning and for bullet resistance. The gas can be ambient air, for example. The intermediate layer is then manufactured simply by that for a distance between the to the intermediate layer adjacent layers is taken care of.

A preferred variant of a transport container of the latter type draws characterized in that the transport container is in two parts and an outer and an inner, separable from the outer container part, of which the walls of the outer container part comprise the first and second layers, while the Walls of the inner container part include the fourth and fifth layers and each other the intermediate layer is between the walls of both container parts. additional Layers can be on both the outer and the inner container part be provided. The inner part of the container must be accordingly in the outer Container part are used so that it is at a distance from the inner walls. Then both containers together offer all the advantages of the above-described, at least five-layer transport container. Are the inner and the outer container in a safe environment, the inner container can outer container can be removed and transported separately. It does it much easier to handle the inner container.

All variants of the transport container are preferably characterized by a Layer in the form of an alarm film with at least one embedded electrical Ladder out. The alarm film can - at least partially - be made of aramid fiber fabric exist in which the electrical conductor (s) are woven. Preferably only one electrical conductor is provided for each wall, which is in the aramid fiber fabric or the alarm foil is laid in a snake shape. Another well-suited one Alarm film consists of a film made of polyethylene (PE) on which the necessary Conductor tracks are printed. The purpose of the alarm foil is to attack the To be able to notice the transport container even when the transport container is not under direct observation. In the event of an attack on the Transport containers regularly damage the electrical Conductor. This can trigger a signal or an alarm system, for example become.

The alarm film is preferably located outside the outer cover layer of the outer honeycomb core. It is preferably covered by a protective layer on the outside preferably consists of aluminum sheet covered. Except for the protective layer then the alarm film is the outermost layer of the transport container and is the first to be damaged in an attack. This can be a corresponding alarm can be triggered early.

Each honeycomb core is preferably made of flame retardant material, and preferably from a light metal such as aluminum. The top layers too Both sides of each honeycomb core are preferably made of flame retardant Material that is preferably light metal such as aluminum. The weight advantage which, for example, aluminum offers, as well as the advantages that result from it show that aluminum is flame retardant are obvious. Moreover Such an aluminum sandwich is also particularly shock-absorbing.

A preferred transport container also preferably has an end layer on the inside of its walls, which is preferably a sheet or a Grid is. The final layer is said to damage the fifth layer Prevent cargo.

A transport container of the type described above preferably has to be opened a locking cage on the inside, with locking elements is provided to lock the transport container. The locking elements are preferably operated remotely. This makes it possible to lock the container in relocate its interior so that it is protected from external attacks as well, like the cargo. The lock can be opened, for example, by radio remote control and be closed.

The access opening to be locked to the inside of the transport container can be opened various of the types known per se can be closed, for example with Use a lid that is also on the back or side wall of the container can be located, or by a bell.

The transport container also preferably has fastening elements for Attach the transport container to a means of transport. transport container and fasteners can be designed so that the transport container represents the structure of a vehicle. In the latter case in particular, the Transport container provided an inner container that fits further into its interior be that can be removed from the transport container and that Transport goods takes up.

As has been found, the transport container according to the invention is advantageous can also be used as a storage container for valuable or dangerous goods.

Components of the cuboid transport container 10 from FIG. 1 are essentially a trough-shaped lower part 12, which on its top with a removable Lid 14 is closed. The lower part 12 is made of one floor and four Sidewalls 16 formed. The lid 14 and the side walls 16 and Bottom of the lower part 12 are constructed in several layers and are by Metal profiles 18 captured and held together.

The structure of the layers is both for the cover 14 and for the side walls 16 and the bottom of the transport container 10 are identical, as in FIG. 2 evident. An outermost layer 20 is formed by an aluminum sheet and serves to protect an underlying alarm foil 22 from damage. The Alarm foil 22 consists of an aramid fiber fabric, into which an electrical conductor 24 is woven in a serpentine pattern. This is easy to see in Fig. 5, the shows the container 10 without the aluminum sheets 20. With the help of the electrical Damage to the alarm foil 22 can be determined automatically on the conductor 24, by triggering a signal once the electrical conductor is anywhere is interrupted. Since it is in the container 10 even without violent attack In individual cases, one of the electrical conductors 24 can be interrupted. is in each alarm foil preferably at least a second conductor loop as Reserve incorporated in the event of failure of the illustrated electrical conductor 24.

A third layer is formed by an aluminum honeycomb core 26 on both sides is laminated with aluminum sheet. The axes of the honeycomb of the honeycomb core are - 1-4 indicated - aligned in the wall thickness direction. From the honeycomb core 26 with its double-sided lamination made of aluminum sheet existing layer is shock absorbing and resists particularly well deforming Attacks, for example with the help of a chisel or a jackhammer. Depending on the material from which it is made, the layer may sawing; however, due to its large thickness, it is unlikely that one Saw is capable of both outer and inner lamination at the same time saw through.

One closes on the inside lamination of the aluminum honeycomb core 26 Layer consisting of three layers, namely an aramid fiber laminate 28, one Plastic layer 30 and another aramid fiber laminate 32. The plastic layer 30 is thus embedded between the two aramid fiber laminates 28 and 32. The plastic layer 30 preferably contains a thermoplastic such as polycarbonate or polyethylene. The three-layer layer made of the two aramid fiber laminates 28 and 32 and the plastic layer 30 is very difficult to cut. This is due to the properties of the aramid fiber laminate, which is both impact resistant is also shockproof and is therefore very difficult to cut because the Cutting a strong fiber pull occurs, which hinders cutting. in the In the event of an attack with an explosive or a welding torch, you will be killed strong and poorly erasable glow of the aramid fiber laminate, which further attacks on the laminate hampered. The plastic layer 30 between the two aramid fiber laminates 28 and 32 has the result that, for example Cutting disc clogged when cutting the three-layer layer. It also comes when cutting with the cutting disc to a lot of smoke and before all to a flow of the plastic into the cut, which is thereby closes again. The flowing plastic is through drawn fibers or Fiber pulp additionally solidified. This makes reopening significant with special needs.

Outside of the outer aramid fiber laminate 28, an additional one may be required thermoplastic layer are provided, which causes the energy-absorbing effect of the aramid fiber laminate 28 in the event of penetration Body comes into play due to the sliding properties of the thermoplastic.

The inner aramid fiber laminate 32 is followed by an intermediate layer made of air or another gas or gas mixture and on the inside of one further aluminum honeycomb core laminated on both sides with aluminum sheet layers 36 is limited. The intermediate layer 34 can be easily thereby manufacture the inner aramid fiber laminate 32 and the second aluminum honeycomb core 36 can be fixed at a distance from each other, so that the intermediate layer 34 arises as a space between the two aforementioned layers. The Intermediate layer 34 is used for securing against firing and for bullet resistance.

On the inside of the inner lamination of the second aluminum honeycomb core 36 is followed by the second three-layer layer, the first layer (or partial layer) is formed by an aramid fiber laminate 38, on the inside of which a plastic layer 40 follows, which in turn on the inside from another position Aramid fiber laminate is covered. The one on the inside of the intermediate layer 34 layers thus correspond to those on the outside of the intermediate layer 34 layers, but they are thinner in the embodiment executed. However, they can also be the same thickness or thicker. On the inside of the innermost aramid fiber laminate 42 is finally a not shown End plate or end grille to damage the walls of the To prevent transport container 10 from the inside.

The layers of the side walls are made of different metal profiles 18 edged and held. Corner profiles 50 connect the layers on different sides 10. Provide spacer profiles 52 over the corners and edges of the transport container for the distance between the layer of aramid fiber laminate 32 and the outer Laminating the honeycomb core 36 to produce the intermediate layer 34.

Like the individual layers, especially at the corners and edges of the transport container 10 butt for the embodiment results from the Figures 2, 3 and 4. In particular from Figures 2 and 3 it can be seen that the Layers 20, 22, 26, 28, 30, 32, 34, 36, 38, 40 and 42 of the floor all in have essentially the same area and exactly one above the other are arranged. In contrast, they have with respect to the respective intermediate layer 34 inner layers 36, 38 and 40 of each side wall have a smaller area dimension than the respective outer layers 20, 22, 26, 28, 30 and 32 of the same Side wall. In addition, the inner layers are opposite the outer layers offset upwards and stand on the inner layers of the floor. Figure 4 also shows that the intermediate layers 34 of the side walls are not connected to each other, but through the inner layers of the Long side walls are interrupted. The inner layers of the long side walls extend between the inner layers of aramid fiber laminate 32 narrow side walls, while the inner layers of the narrow side walls extend between the inner layers of the long side walls. At the Cover 14, the layers are designed so that their inner layers closed lid between the inside of the side walls. The outer layers of the cover 14 lie with their inside on the upper edges the inner layers of the side walls. The corner profiles 50 of the cover have each centering bevels 54, which with corresponding counter bevels 56 to the interact upper spacing profiles 52 of the side walls.

Inside the transport container is a multi-part only shown in Figure 6 Locking cage 60 arranged. The locking cage 60 comprises two U-shaped ones Frame parts 62, which are fixed to the longitudinal side walls and the bottom of the Transport container are connected. When the transport container 10 is closed the two free ends of each U-shaped frame part 62 by one each Locking bar 64 connected to each other. The total of two locking bars 64 are attached to the inside of the lid. The frame parts 62 and the locking bars 64 each consist of square profiles. The locking bars 64 can not with the locking frame parts 62 by means of a shown, radio-controlled locking mechanism must be locked. This lock is thus protected from external access inside the Transport container 10 instead. To open the transport container 10, the locking mechanism unlocked by remote control. Then the Lid 14 can be removed from the lower part 12 of the transport container 10.

An inner final layer, for example in the form of a sheet, a grid or another plastic layer to protect the inner aramid fiber layers 42 is not shown in the figures, but can be on the inside of the locking cage 60 or between the aramid fiber layers 42 and the locking cage 60 be provided.

In other embodiments of the transport container, for example with a different or different opening, the locking cage is below Under certain circumstances executed differently than in the embodiment.

In addition to the embodiment of the transport container 10 shown in the figures it is also possible, for example, to set up means of transport as a transport container of the type described. Depending on the type of transport container the goods to be transported can be stored in a separate container in the interior of the transport container 10 are stored. Neither in the figures different fasteners are shown to the transport container to be able to attach various means of transport.

It has been found that a transport container of the type described one Attack in the introductory sense using commercially available, portable withstands mechanical tools for far longer than required and great shock absorption, low weight and great security against intrusion Distinguishes parts. It is also very heat-resistant.
