Abstract

An armour-plating system for system openings at penetration-resistant security receptacles in various versions of embodiments which are interrelated so that they form a unified invention concept that resolves the technical problem of protecting penetration-resistant security receptacles with more versions of armour-plating system around system openings (2) in a wall or door (1) against intrusion by means of various burglary tools with impact option, grinding/slitting, thermal and combined burglary tools. 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

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 41H 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.
From the UK Patent Application GB 2 060 564 A there is a known solution of a security container which is used to carry and/or transport valuable articles from place to place and is so designed as to protect them against unauthorised and/or prohibited access. It is constructed from a floor section, two side wall sections, two end wall sections and a roof section. One of the side wall sections has a door, an escape hatch and a cash hatch, whereas the roof section has ventilation openings. The side wall section comprises a series of spaced vertical members, consisting of metal plates welded between two T-section metal members. The sections have a single thickness outer wall which is welded to them by vertical welds, and a double thickness inner wall, whose inner sheet is welded to each member by a vertical weld, whereas the outer sheet is welded to the inner sheet.
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 characteristics 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 above described technical problem is resolved by the armour-plating system around system openings at penetration-resistant security receptacles which is so constructed that its basic construction for the protection of the zone 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 at least 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:

The four versions of the basic construction of the armour-plating system for protecting system openings at penetration resistant security receptacles, shown in Figures 1 - 8, are not a constituent part of the present invention. These versions are included with the aim to facilitate better understanding of the present invention, whose embodiments are shown in Figures 9 - 20.
Fig. 1 and Fig.2 show the first, basic version of basic construction 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 inner surface of the wall or door 1 of the exterior 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, improved version of basic construction of the armour-plating system, which differs from the one shown in Fig. 1 and Fig. 2 in 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 in 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, improved version of the basic construction 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, improved version of the basic construction of the 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 first embodiment of the armour-plating system according to the present invention, which differs from the previously described versions 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 11 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 11 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 bearing 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 11 can be made from more individual blocks, of regular or irregular geometric forms, which are arranged in close fit along the entire bearing 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 second embodiment according to the present invention, the embodiment shown in Fig. 15, Fig. 16 and Fig. 17 represents the third, and the embodiment in Fig. 18, Fig. 19 and Fig. 20 represents the fourth embodiment according to the present invention.
The movement of the sintered corundum inserts 11, 12, 13 and 14 in the embodiments shown in Figures 9 - 20 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 embodiments according to the present invention also the space between the aforesaid inserts 11, 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 embodiment according to the present invention that in some other, not shown, embodiment there is a clearance of 0,3 up to 0,8 mm between the aforesaid box construction and inserts 11, 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 appropriate 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 of embodiments represents the armour-plating system around system openings 2, of various shapes and sizes, in doors or walls 1 of security receptacles. Its advantage is that, depending on a selected version, it offers increased resistance against penetration by means of various known burglary tools.
