This invention relates to an armour-plating system for protecting system openings at penetration-resistant security receptacles, and compπses more versions of walls and/or security bamers 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,

1 U whose armoured elements, of a relatively small thickness, are characteπsed by mateπal

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 ι t

The technical problem being resolved with the present invention is such a construction ofthe armour-plating system for protecting system openings at penetration- resistant secuπty receptacles that will, in vaπous versions of embodiments of armour- plating system around system openings, ensure equal penetration-resistant features of all

2 C component parts of secuπty receptacles, including system openings, due to which an increased level of protection against intrusion through system openings by means of vaπous types of burglary tools (e g electπc rotary with impact option, electπc gπnding/shtting. thermal tools or a combination of burglary tools and/or miscellaneous specially made tools), will be ensured, whereby the penetration into secuπty receptacles

25 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 vaπous known solutions for the protection of system openings at penetranon-resi stant secuπty receptacles, such as office cabinets, money safes of

30 different levels of protection, vaults, deposit safes, housings of automated teller machines, and similar

At the most widely applied known solution the aπnoured 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 characteπ sties ofthe system opening to those of other component parts of a secuπty receptacle

At another known solution the armoured part around system openings is reinforced by aluminium corundum armoured plate Despite offering good resistance against electπc gπnding/s ttmg and thermal burglary tools, this known solution has a disadvantage due to low resistance against electπc 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 electnc gπnding/shtting 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 Accordmg to this invention the armour-plating system around system openings at penetration-resistant security receptacles is so constructed that the basic construction for secuπty barπer structure around system openings compπses 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 fiπnly fixed Thev are made of the same mateπal as the basic armoured plate, or they can be made from a different mateπal, which goes also for the inserts used for vaπous possible versions of embodiments

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 descπbed receptacle is enclosed with the basic armoured plate 4 which is fixed to the inner surface of the wall or door 1 of the exteπor wall of a receptacle in such a way that it is placed within the framework ofthe 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 descπbed 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 mteπor 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 having around the system opening 2 armoured plate sections 5, which are made from the same mateπal as the basic armoured plate 4 and are welded onto the basic armoured plate 4 or fixed to it m some other wa> at a πght 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 s>stem which differs from the previously descπbed 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 aπnoured plate 4 or fixed onto it in some other way at a πght angle. they are made from the same mateπal as the plate sections 5 and the basic armoured plate 4, whereby in this version of embodiment they together with plate sections form in transverse cross-section a vertical U-shape In some other embodiment the plate sections 6 can be s welded onto the basic armoured plate 4 at some other obtuse or shaφ angle This version of embodiment offers even higher resistance against thermal burglary tools and tools with impact option than the previously descπbed two versions

Fig 7 and Fig 8 show the fourth version of embodiment of armour-plating system which 10 differs from the previously descπbed 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 1 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 geometπc form The plate sections 7, 9 and 10 are made from the same fire

20 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 descπbed fourth version in having an insert 11 in the form of a block from sintered corundum Al 0-i of at least 92,5% puπty inserted m 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 wav (Fig 8) The insert 1 1 is preferably inserted and or placed along the whole length of the hollow

30 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 vaπous 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 descπbed 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 ofthe 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 descπbed 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 tπangular 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 descπbed embodiment shown in Fig 12. Fig 13 and Fig 14 represents the sixth version the embodiment shown in Fig 1*\ 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 πgidly 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 secuπty receptacle by means of thermal or gπnding/slitting burglary tools will be greatl} 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 mateπal 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 vaπous 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 vaπous known burglary tools
