Description

The invention relates to a storage container for objects to be protected against unauthorized access, namely a safe, a cash dispenser or a security locker, comprising a housing with a door and an interior for accommodating the objects, the absorber element having one, two large surfaces and side surfaces connecting them an inner wall is arranged, which absorbs energy generated during an explosion and consists of a plate consisting essentially of fibers and a holder. The invention furthermore relates to an absorber element for a storage container for objects to be protected against unauthorized access, namely a safe, safe, ATM or security safe, comprising a housing with a door and an interior space with internal walls for receiving the objects, which energy is generated in the event of an explosion absorbed and consists of a plate made essentially of fibers with two large surfaces running parallel to one another and four side surfaces connecting these surfaces and a holder.

Generic storage containers and absorber elements are known from the prior art. The EP 2 137 368 B1 discloses a generic storage container, consisting of a housing having a storage space, which consists of a rear wall, two side walls, which are arranged opposite one another, a floor and a ceiling, so that the container has the required security against burglary. Floor and ceiling are arranged opposite each other and connected to each other via the side walls. The housing has at least one opening which can be closed with at least one door and / or flap. In this storage container, it is provided that an absorber element is arranged in the storage space, which absorber element has a high pore volume and absorbs energy that arises suddenly in the event of an explosion. Accordingly, this prior art also discloses a corresponding absorber element for a container for storing objects to be protected against unauthorized access.

This previously known container and also the known absorber element for this container have proven themselves in practice, so that a container formed with such an absorber element is adequately protected against unauthorized opening by explosion, the explosion by introducing and then igniting an explosive gas he follows.

ATMs, for example, are being blown up increasingly by using solid explosives. Such a solid explosive is introduced into the interior of an automated teller machine in the required amount, for example via a cash dispensing slot, and then detonated. This procedure places new demands on generic storage containers and also on corresponding absorber elements which are arranged in such a storage container.

The invention is therefore based on the object of developing a storage container or an absorber element in such a way that, in addition to the requirements of high security against being blown up by gaseous explosives, there is also a high level of security against being blown up by solid explosives. In addition, there is the task of designing such an absorber element in such a way that it can be used in a simple manner in conventional storage containers and at the same time can also be produced inexpensively.

To solve this problem, it is provided in a storage container according to the invention or an absorber element according to the invention that the holder consists of a base element for connection to the inner wall and for contacting a large surface of the absorber element and a fastening element, the side surfaces of the absorber element being as free as possible from a cover are formed by the fastener.

In the storage container according to the invention and the same also applies to the absorber element according to the invention, the holder for the absorber element is therefore designed in such a way that the side surfaces of the absorber element, namely at least a large surface and the side surfaces adjoining them at right angles in the usual way are as free as possible of a cover, so that these areas are available for effective explosion protection.

Such a holder is designed, for example, by a lattice-like or cage-like element which surrounds the plate made of fibers and is connected directly or indirectly to the base plate, so that the plate made of fibers rests on the base plate and the side surfaces and that of the base plate Large surface facing away from the plate consisting of fibers are only covered by narrow webs. As a result, the pressure wave can be reduced in the event of an explosion from a very large surface area of the absorber element even if such an absorber element is only of small volume. Preferably a maximum of 10% of the Entire surfaces facing the interior of a storage container are covered by the holder, individual components of the holder being formed with a very small width of at most 3 mm, preferably less than 2 mm.

The bottom element can also be part of the inner wall of the housing, for example.

As a rule, several absorber elements in the form of a kit are used in a storage container in which the free surfaces of the inner walls are fitted with these absorber elements. These surfaces can be optimally covered by low-volume absorber elements, with no further cutting work being required during installation. During installation, therefore, completely produced absorber elements consisting of the plate and the holder can be installed without it being necessary in terms of assembly technology to insert the plate made of fibers, for example, into the holder.

Only complete and complete absorber elements are used during assembly. The absorber elements are preferably cubic, in particular with a square base.

According to a further feature of the invention, it is provided that the fastening element consists of at least one, preferably at least two crossing, in particular U-shaped bracket elements, which have two legs and a web connecting the legs, the legs with their ends facing away from the web are connected to the floor element. The leg and the web consist, for example, of a metal wire and have a round cross section. The diameter of the legs and web is preferably less than 2 mm.

In this embodiment, the bracket elements run, for example, diagonally over the fastening plate and therefore intersect in the center of gravity of the base element. However, there is also the possibility that the bracket elements run at right angles to one another in such a way that they are fastened with one leg each at the center of two edges of the base element which are aligned parallel to one another.

Combinations of the two embodiments shown above are also conceivable, so that, for example, three or four bracket elements are correspondingly connected to the base element. This essentially depends on the arrangement of the absorber element in the storage container. Care must be taken to ensure that the plate, which essentially consists of fibers, cannot slip out of the holder, so that, for example, the plate, which essentially consists of fibers, must be supported by the holder in the region of the side faces of the plate when the absorber element is on vertically arranged side walls of the storage container is attached.

A further embodiment of the storage container according to the invention provides that the bottom element has raised edges in its edge regions, which are connected to the fastening element. These upstands have the advantage that, in particular when the absorber elements are fastened to vertically aligned inner walls, the panel, which essentially consists of fibers, is supported by such an upstand, so that here, however, only a very small proportion of one side surface of the panel is covered by the upstand and the plate is held by, for example, bracket elements. In this embodiment, it is advantageous if the surface of a backsplash does not cover more than 10% of the side surface.

It is also conceivable that the holder as a whole consists of a cage-like grid element, the base element being inserted into the grid element and possibly being connected to the grid element.

In order to improve the protective effect of the absorber element in the storage container, it is provided that the upstands have openings which are also provided for the passage of the pressure wave.

According to a further feature of the invention, it is provided that the absorber element is designed with a decreasing bulk density and / or material density starting from its surface facing the interior towards its surface facing the interior wall. It has been found that such a configuration of the pressure wave facilitates entry into the absorber element and the energy of the pressure wave has an energy-reducing effect due to the bulk density or material density of the plate consisting of fibers, which increases in the direction of movement of the pressure wave. With regard to the bulk density, it must be assumed that this relates to the density of the plate. Here, for example, a multi-layered plate body can be used, which consists of identical fibers, but the layers have different bulk densities, i.e. the fibers are arranged more or less close together, which of course also results in a different pore volume.

With regard to the material density, it must be stated that this relates to the density of the materials used, so that, for example, a multilayer plate can be used which has layers of different materials with different densities. Mineral fibers can be used here as well as metal fibers.

Comparable results are achieved in that the absorber element is designed with a decreasing pore volume and / or with a decreasing size of the pores, starting from its surface facing the interior towards its surface facing the interior wall. Such a configuration is of course also possible in combination with the corresponding decreasing bulk density and / or material density.

Alternatively and, of course, in addition, it can be provided according to a further feature of the invention that the absorber element, starting from its surface facing the interior toward its inner wall, is formed with fibers having a fiber cross-section with a decreasing area size of the fiber cross-section.

Furthermore, it can be provided that the absorber element, starting from its surface facing the interior in the direction of its surface facing the interior wall, is formed with fibers whose thermal conductivity decreases in W / (mK). Due to the variations shown above within the absorber element, i.e. Within the plate, which essentially consists of fibers, properties are achieved within the plate which have an energy-reducing effect on a pressure wave, so that the pressure wave which arises in the event of an explosion can be reduced via the absorber element in such a way that damage to the storage container does not occur or at least occurs can be restricted to such an extent that unauthorized access to the interior of the storage container is denied. In particular, such a storage container or the associated absorber element also protects a building against explosion damage, for example when an automatic teller machine is blown open.

According to a further feature of the invention, it is provided that the absorber element consists of layers with fibers, the fibers of the individual layers being designed differently. As already explained above, these can be mineral fibers, for example rock wool fibers, slag fibers, glass fibers or also metal fibers, in particular steel fibers. The fibers can, for example, have an essentially rectangular, in particular square, cross section. However, fibers with a round cross section are also suitable.

According to a further feature of the invention, it is provided that the absorber element has a film cover which is arranged, in particular, over the entire surface on the surface of the absorber element facing the interior. This foil cover has the advantage that loosened fibers are prevented by the foil cover from getting into the interior of the storage container, where they can also get into the area of electronic components, for example, and are possibly responsible for damage or malfunctions. This applies in particular to the use of metal fibers, which of course can also cause short circuits in electronic components. The film cover is designed in such a way that it dissolves when the pressure wave hits it, or at least opens in such a way that the pressure wave can then be broken down in the plate, which essentially consists of fibers.

It has also proven to be advantageous to magnetically design the base element of the holder. Corresponding storage containers are usually made of steel, so that the absorber element can be attached using magnetic forces. The magnetic configuration of the base element has the advantage that the base element and thus the entire absorber element can be attached to the inner wall of a storage container in a simple manner and without additional fastening means. In addition, there is the advantage that the absorber elements can be removed from the inner wall in a simple manner, for example in order to arrange them again in a different arrangement. Of course, other fastening methods are of course also conceivable, such as, for example, gluing the absorber elements to the inner wall of the storage container.

The advantages and features of the storage container described above also apply to the absorber element according to the invention. It is therefore explicitly referred to these advantages.

The door 7 has a locking mechanism of conventional design, not shown, which has a locking device 9 , for example a keyboard can be actuated. The door also points 7 a handle 8th on the manual handling of the door 8th serves, but can also have the function of actuating the locking mechanism as soon as via the locking device 9 a code that corresponds to the locking secret has been entered.

In addition to the in 8th illustrated embodiment with a locking device 9 in the form of a keyboard there is of course also the possibility that the locking mechanism can be operated in the usual way with one or two mechanical keys.

The sidewalls 3rd , the floor 4th , the ceiling 5 and also the rear wall of the safe, not shown in detail 1 represent walls made of sheet metal so that they are magnetic. The door can be used in the same way 7 as the wall of the safe 1 be considered, which can thus also be designed in accordance with the above statements.

The in 8th shown vault 1 represents only an exemplary embodiment. The embodiments of an absorber element described below 10th according to the 1 to 7 are used in particular in ATMs in order to open one in the sense of a safe 1 To be able to prevent trained storage containers with gaseous or solid explosives or to mitigate the explosive effect in such a way that in any case access to the interior of the safe 1 is not possible or at least difficult, so that attempts to break in cannot lead to success in a short time.

For this purpose are in the interior of the safe 1 in 8th Absorber elements not shown 10th arranged. The absorber element 10th is here on inner walls 11 inside the safe 1 attached.

In the 1 to 7 are different embodiments of the absorber elements 10th shown, which are described below.

An in 1 represented absorber element 10th consists of a plate essentially made of fibers 12th , in the 6 is shown in more detail. The plate 12th is multi-layered and has in the 6 illustrated embodiment three layers 13 , 14 , 15 on, which are designed differently in terms of both their material thickness and at least one further material property. The layers 13 , 14 and 15 are in a foil cover 16 arranged covering all areas of the layers 13 , 14 and 15 and thus the plate 12th covers, so that individual fibers emerge from the plate 12th in the interior of the safe 1 is prevented.

The layers 13 , 14 and 15 can one starting from the first surface 17th towards the second surface 18th have decreasing bulk density and / or material density. Here is the surface 18th the surface that of an inner wall 11 is facing and that on the inner wall 11 is attached, as will be described below. It This is a large surface that can be distinguished from a side surface 19th . every layer 13 , 14 and 15 has four sides 19th on that are perpendicular to the surfaces 17th , 18th and aligned with each other so that each layer 13 , 14 and 15 is cuboid. Accordingly, the plate is too 12th cuboid-shaped, here, for example, the special design of a cube is also conceivable.

In addition or alternatively, the layers can 13 , 14 and 15 differ in terms of their pore volume and / or in terms of their pore size, the pore volume and / or the pore size within the plate 12th starting from the first surface 17th towards the second surface 18th is designed to decrease.

Furthermore, the layers can 13 , 14 and 15 with regard to the area size of the fiber cross-section, which distinguish the fibers having such a fiber cross-section, here also starting from the first surface 17th towards the second surface 18th a decreasing area size of the fiber cross section can be provided. It should be noted that the material properties as described above in each layer 13 , 14 and 15 over the entire volume of the layer 13 , 14 and 15 can be the same or that even within the layers 13 , 14 , and 15 there is a structure corresponding to a gradient described, so that, for example, also within the layers 13 , 14 and 15 the material properties are designed to decrease in the direction described.

It is also possible that starting from the first surface 17th towards the second surface 18th the layers 13 , 14 and 15 or the plate 12th has a decreasing thermal conductivity.

The fibers in the layers 13 , 14 ., 15 can be formed from different materials, in particular mineral wool fibers and steel fibers being provided.

Next to the plate 12th the absorber element has a holder 20th on that from a bottom plate 21 which exists in their edge areas 22 Upstands 23 having. Furthermore, the bracket 20th a fastener 24th on which serves the plate 12th on the bottom plate 21 attach so that the entire bracket 20th with the plate 12th is present as a one-piece component, which is in the region of the inner wall 11 of a vault 1 is attachable.

In 1 it can be seen that the upstand 23 Breakthroughs 25th Has.

The fastener 24th is designed such that the fastening element 24th smallest possible areas of the plate 12th covers. This is shown, for example, in the embodiment according to 1 achieved in that the fastener 24th from several U-shaped bracket elements 26 consists of two legs each 27 and one thigh 27 connecting web 28 exhibit. The bracket elements 26 are with the free ends of the legs 27 with the bottom plate 21 connected, for example, the free ends of the legs 27 on the end faces of the upstands 23 on and are attached there.

The 2nd shows a corresponding embodiment of a holder 20th with several bracket elements 26 . Recognizable in the embodiment according to 2nd is that the bottom plate 21 consists of four interconnected strip elements, so that the base plate has a rectangular opening in the central area 29 having. The bottom plate 21 is designed magnetically and can therefore be easily with an inner wall 11 of the metal safe 1 get connected.

In the embodiment according to 2nd are the thighs 27 of the individual bracket elements 26 with the bottom plate 21 connected in such a way that the webs 28 perpendicular to the edge areas 22 are aligned. All in all, this results in a right-angled arrangement of the edge regions running in each case between parallel 22 aligned bracket elements 26 .

Alternative embodiments are in the 3rd and 4th shown, for example the 3rd shows an embodiment in which two bracket elements 26 are provided, the webs 28 parallel to the two diagonals of the base plate 21 are aligned. Such an embodiment represents approximately the entire side surfaces 19th the plate 12th free.

With an arrangement of such an absorber element 10th on a vertically aligned inner wall 11 of the vault 1 it has proven to be advantageous to have two additional bracket elements 26 to provide that with her thighs 27 each in the middle of an edge of the base plate 21 are attached. Such an embodiment is in 4th shown.

A different configuration is shown in 5 shown. In this embodiment, the fastener is 24th in the form of a cylindrical rod 30th formed with one end on the bottom plate 21 is attached and the cantilever arms arranged in pairs at its second free end 31 has that on the surface 17th the plate 12th rest and so the plate 12th with the bottom plate 21 connect.
