The preferred and very safe embodiment of the invention comprises a basic armoured plate (4) which together with plate sections (5, 6, 7, 9, 10) forms around the system opening (2) a closed box construction into which at least one of the inserts (11, 12, 13, 14) is incorporated together with elastic filling. All the described versions of embodiments are component parts of the present invention.

Description

ARMOUR-PLATING SYSTEM FOR PROTECTING SYSTEM OPENINGS AT PENETRATION-RESISTANT SECURITY RECEPTACLES

This invention relates to an armour-plating system for protecting system openings at penetration-resistant security receptacles, and comprises more versions of walls and/or security barriers of vaults or safes and/or, more particularly, more versions of armour plating for doors, security barriers or walls with one or more system openings, whose armoured elements, of a relatively small thickness, are characterised by material.

According to the international classification of patents (ICP) the present invention is classified into E 05G 1/024 and into F 41 H 5/02, and additionally into E 06B 5/10 and into E 04C 2/02.

The technical problem being resolved with the present invention is such a construction of the armour-plating system for protecting system openings at penetration-resistant security receptacles that will, in various versions of embodiments of armour-plating system around system openings, ensure equal penetration-resistant features of all component parts of security receptacles, including system openings, due to which an increased level of protection against intrusion through system openings by means of various types of burglary tools (e g electric rotary with impact option, electric grinding/slitting. thermal tools or a combination of burglary tools and/or miscellaneous specially made tools), will be ensured, whereby the penetration into security receptacles through system openings will be greatly hindered, no matter where the system openings are located, and at the same time the whole construction of security receptacles will be compact and simple, but receptacles well-protected against intrusion

There are various known solutions for the protection of system openings at penetration-resistant security receptacles, such as office cabinets, money safes of different levels of protection, vaults, deposit safes, housings of automated teller machines, and similar. At the most widely applied known solution the armoured part around system openings is made from the same armoured plate and filling as the rest of the walls and doors of the receptacle, only that the said armoured part is thicker and/or reinforced Despite being simple and inexpensive, this known solution has a disadvantage when a system opening is located near the joint edges of door and housing, in which case this known solution does not ensure equal penetration-resistant characteristies of the system opening to those of other component parts of a security receptacle.

At another known solution the armoured part around system openings is reinforced by aluminium corundum armoured plate Despite offering good resistance against electric grinding/slitting and thermal burglary tools, this known solution has a disadvantage due to low resistance against electric tools with impact option

There is another known solution at which the armoured part around system openings is reinforced with an armoured steel plate with high content of manganese This known solution offers also high resistance against the tools with impact option, but its disadvantage is that it does not offer enough resistance against electric grinding/slitting and thermal burglary tools

The disadvantage that all the aforesaid known solutions have in common is that they offer resistance only against some types of burglary tools, not against all the known ones, which at the same time also represents the unsolved technical problem

The present invention eliminates the aforesaid disadvantages of the known solutions According to this invention the armour-plating system around system openings at penetration-resistant security receptacles is so constructed that the basic construction for security barrier structure around system openings comprises a basic armoured plate from fire-resistant steel with more than 23% Cr and more than 19% Ni content, onto which one or more plate sections of different shapes and sizes are firmly fixed. They are made of the same material as the basic armoured plate, or they can be made from a different material, which goes also for the inserts used for various possible versions of embodiments. The embodiments of the present invention will now be described, by way of example, with reference to the accompanying schematic drawings which show:

Fig. 1 and Fig.2 show the first, basic version of embodiment of the armour-plating system The system opening 2 in a wall or door 1 of a not shown and not described receptacle is enclosed with the basic armoured plate 4 which is fixed to the inner surface of the wall or door 1 of the exterior wall of a receptacle in such a way that it is placed within the framework of the wall or door 1 The inner part of the said framework of the wall or door 1 is entirely filled with filling 3, reinforced with not shown and not described armature, with which also other component parts of a receptacle are filled In some other version of embodiment the basic armoured plate 4 can be placed and fixed also on the wall or door 1 of the interior wall of the receptacle, and can be made from one, two or more sections The basic armoured plate 4 is made from fire resistant steel containing more than 23% Cr and more than 19% Ni

Fig. 3 shows the second version of embodiment of armour-plating system, which differs from the one shown in Fig. 1 and Fig.2 m having around the system opening 2 armoured plate sections 5, which are made from the same material as the basic armoured plate 4 and are welded onto the basic armoured plate 4 or fixed to it m some other way at a right angle or at some other angle. The plate sections 5 can be made of more pieces or can be made as a single piece forming a single framework. The armoured system according to this version of embodiment offers increased resistance against thermal burglary tools and tools with impact option.

Fig. 5 and Fig. 6 show the third version of embodiment of the armour-plating system which differs from the previously described second version in having also plate sections

6 welded onto the basic armoured plate 4 around the system opening 2 Plate sections 6 can be made from more individual pieces or as a single piece, and are welded onto the basic armoured plate 4 or fixed onto it in some other way at a right angle. they are made from the same material as the plate sections 5 and the basic armoured plate 4, whereby in this version of embodiment they together with plate sections 5 form in transverse cross-section a vertical U-shape In some other embodiment the plate sections 6 can be welded onto the basic armoured plate 4 at some other obtuse or sharp angle. This version of embodiment offers even higher resistance against thermal burglary tools and tools with impact option than the previously described two versions.

Fig.7 and Fig.8 show the fourth version of embodiment of armour-plating system which differs from the previously described third version in having onto plate sections 5, 6 around system opening 2 welded or fixed in some other way also plate section 7 in one or more pieces, which runs parallel to the basic armoured plate 4 so that all plate sections together form in transverse cross-section a box-shaped profile of a regular rectangular form with a hollow space 8 along the whole length, which can be closed on both sides with a plate section 9 on one side and plate section 10 on the other side In some other embodiment the plate sections 7, 9 and 10 can be fixed also at some other angle so that together with plate sections 5 and 6 and the basic armoured plate 4 they form a closed box-shaped profile, which can be in transverse cross-section of any regular or irregular geometric form. The plate sections 7, 9 and 10 are made from the same fire resistant steel as the basic armoured plate 4 and plate sections 5 and 6. This version of embodiment offers even higher resistance against thermal tools and tools with impact option than the aforesaid versions

Fig. 9, Fig.10 and Fig.11 show the fifth version of embodiment of the armour-plating system which differs from the previously described fourth version in having an insert 11 in the form of a block from sintered corundum Al₂O₃ of at least 92,5% purity inserted in close fit into the hollow space 8, formed by plate sections 5,6,7,9 and 10 and basic armoured pate 4, which are welded onto each other or fixed in some other way (Fig.8). The insert 1 1 is preferably inserted and/or placed along the whole length of the hollow space 8 and all around the system opening 2, whereby in some other embodiment due to the location of the system opening 2 next to the edge of the wall or door 1 of a receptacle, the said insert can be placed only along one, two or three edges of system opening 2 Preferably the insert 1 1 is made as one block, but in some other embodiment it can be made also from more blocks forming a close-fitting string. Again, in some other embodiment the insert 11 can be arranged in two or more close-fitting parallel courses, whereby the beanng surfaces between the courses are preferably parallel to the basic armoured plate 4, but in some other embodiment they can be fixed at some other angle and can be placed/arranged one against the other at various angles. The insert 11 is in transverse and longitudinal cross-section of a rectangular shape, but in some other embodiment the said insert can also be of any regular or irregular geometric shape In multi-course embodiment each of sintered corundum courses of the insert 1 1 can be made from more individual blocks, of regular or irregular geometric forms, which are arranged in close fit along the entire beanng surface, whereby, in that case, the blocks are laid in running-bond pattern with the vertical joints of one course being off-set on the blocks in the next course One of the previously described possible embodiments is shown in Fig. 12, Fig. 13 and Fig. 14, whereby the insert 12 from sintered corundum blocks is arranged in two courses consisting of more successive rectangular blocks, whereby both courses are of the same form, which goes also for the blocks forming them whose vertical joints of one course are off-set on the blocks in the next course.

Another possible previously described embodiment of a two-layer insert 14, with each layer made as one block, is shown in Fig. 18, Fig. 19 and Fig. 20 In this embodiment, each block is in cross-section of a regular triangular form, whereas both layers joined to form the insert 14 are of a regular rectangular shape and their joint and/or adjacent surfaces run diagonally Fig. 15, Fig. 16 and Fig. 17 show the embodiment in which the insert 13. like the insert 12 in the embodiment shown in Fig. 12. Fig. 13 and Fig. 14, is arranged in two courses which consist of more blocks of a rhomboid form, whereby the blocks of the first course are turned into the opposite direction to the blocks in the second course

The previously described embodiment shown in Fig. 12, Fig. 13 and Fig. 14 represents the sixth version the embodiment shown in Fig. 15, Fig. 16 and Fig. 17 represents the seventh version, and the embodiment in Fig. 18 Fig. 19 and Fig. 20 represents the preferred eighth version of embodiment.

The movement of the sintered corundum inserts 1 1, 12, 13 and 14 in the embodiments from the fifth to the eighth version must be rigidly limited and/or made impossible by close-fitting and enclosing hollow box construction formed by the basic armoured plate 4 and plate sections 5, 6, 7, 9 and 10. Only in that case the intrusion into a security receptacle by means of thermal or grinding/slitting burglary tools will be greatly hindered due to the fact that it will not be possible to push apart any insert 11 , 12, 13 and 14 in transverse, longitudinal or radial direction In all the said versions of embodiments also the space between the aforesaid inserts 1 1, 12, 13 or 14 and the box construction is preferably filled with elastic filling, such as glue or any other elastic material which after treatment retains elasticity In some other embodiment the elastic filling may also be left out It is also true for all the said versions that in some other embodiment there may be clearance of 0,3 up to 0,8 mm between the aforesaid box construction and inserts 1 1 , 12, 13 or 14, which can also be smaller or larger than that, whereby the best test results were obtained at a clearance within the said range.

The test results also show that the most appropnate thickness of the inserts 11, 12, 13 or 14 from sintered corundum and/or their individual courses in two- or multi-course embodiments is at least 5 mm or more, and their length and height and/or height and length of individual blocks in the embodiments at least three times or more times larger than their thickness and/or the thickness of an individual block. The present invention in all versions of embodiments represents the armour-plating system around system openings 2, of various shapes and sizes, in doors or walls 1 of secunty receptacles Its advantage is that, depending on a selected version, it offers increased resistance against penetration by means of various known burglary tools.
