Description

Field of the invention

The present invention relates to a framed, transparent, bullet-resistant glazing with reinforced edge area.

Moreover, the present invention relates to a method for producing the framed, transparent, bullet-resistant glazing with reinforced edge area.

Last but not least, the present invention relates to the use of the framed, transparent, bullet-resistant glazing with reinforced edge area.

State of the art

The prior art cited in the present application is incorporated by reference.

Monolithic bulletproof glazings or bulletproof glass based on laminated safety glass are known. By way of example, the European patent application EP 2 434 249 A1 , the European patent EP 1 004 433 B1 , the German utility model DE 20 2011 001 371 U1 or the German patent applications DE 44 15 879 A1 . DE 41 42 416 A1 . DE 100 48 566 A1 . DE 197 45 248 A1 , the American patent US 8,789,324 B2 and the American patent application US 2003/0190439 directed. These bullet-resistant glazings do not provide complete safety against splinters, especially when bombarding their critical areas.

As far as the protection against splinters is concerned, this comes from the European patent application EP 0 528 354 A1 known, bullet-resistant insulating glass element with a certain improvement. In this insulating glass element behind the monolithic ballistic block, ie on the side facing away from the attack side, a single disc arranged as insulation, which, if the bombardment is not too violent, can absorb outgoing splitter.

After the test in accordance with DIN EN 1522 and DIN EN 1523 for the determination of the firing class, one part of the standard is analogous so that the system test (system = glass unit + frame) is carried out by bombardment at the supposedly most critical point shall be. For some time, the fire departments have reinterpreted the interpretation of this passage and fire at an angle of 90 ° with the ammunition corresponding to the test firing class on the edge area. For this purpose, three shots along the edges with a distance of 120 mm are given along one edge. The distance to the edges is not exactly defined, but it is in the range of 15 mm to 40 mm. Particularly critical is the impact on the corner of the system. For the inner part of the system, the bombardment angle of 90 ° is normal and not critical.

As a sign of the failure of the system is a splitter outlet on the protective side.

Accordingly, it was the object of the present invention to provide a framed, transparent, shatterproof, bullet-resistant glazing, which no longer has the disadvantages of the prior art. In particular, the novel glazing should be able to be produced in a simple manner and, if at all, with only very low reject rates.

These and other objects are achieved according to the proposal of the invention by the framed transparent, bullet-resistant glazing with reinforced edge region, the process for their preparation and their use with the features of the independent claims. Advantageous embodiments of the invention are given by the features of the subclaims.

Detailed description of the invention

The present invention relates to a framed, transparent, bullet-resistant glazing with reinforced edge area.

"Bombardment-resistant" means that the glazing complies with the tests according to DIN EN 1522 and DIN EN 1523 and does not show splinters into the protected area when bombarded in the edge area. Furthermore, the classification and requirements for ballistic block testing are regulated by the European standard EN 1522.

The distance is determined by at least one spacer, which rotates at least one edge region of the ballistic block. This results in at least one thermally insulating disc space. Thus, the additional glass pane or the additional glass panes can be arranged on the attack side and / or the protective side of the glazing according to the invention.

Preferably, the spacer is constructed from at least one bullet-resistant, flame-retardant or non-combustible material. Examples of suitable materials of this kind are metals, in particular non-corroding metals such as stainless steel or anodized aluminum, or flame-retardant, high-temperature resistant plastics which char in case of fire and / or form a solid carbon foam.

Detailed description of the figures Figures 1 and 2

The FIG. 1 shows a vertical longitudinal section through a section of an embodiment of a framed, transparent, bullet-resistant glazing 1 with an insulating glass unit 2.4, 3, 2, 5 and a ballistic block 2 on the attack side A according to the prior art.

The insulating glass unit 2.4, 3, 2, 5 and the ballistic block 2 of the known glazing 1 had the dimensions 0.5 mx 0.5 m, as they are common for bombardment, and was in a suitable bullet-proof steel frame 6, 6.1, 6.2 fixed, wherein the gap 8 a clear width of 4 mm between the ballistic block 2 and the insulating glass unit 2.4, 3, 2, 5 on the one hand and the frame 6 on the other hand by two circumferential sealing lips 7 was sealed from a flame-retardant, elastomeric elastomer to the outside. At the same time, the sealing lips 7 fixed the arrangement of ballistic block 2 and insulating glass unit 2.4, 3, 2, 5 in the steel frame. 6

The glass sheet 2.4 of the insulating glass unit 2.4, 3, 2, 5 was a 4 mm thick tempered float glass sheet, and the peripheral spacer 5 was a square pipe made of anodized aluminum having a square cross section with a side length of 10 mm and a wall thickness of 1 mm. The spacer 5 was adherent with a glass-metal adhesive connected to the surface of the ballistic block 2 and the inside of the glass pane 2.4, so that a space between the panes 3 a clear width of 10 mm resulted.

The ballistic block 2 was constructed of two 5 mm thick float glass panes 2.1 and a 6 mm thick polycarbonate pane 2.2 arranged therebetween. The assembly was held firmly together by two 1.3 mm thick adhesive films 2.3 made of polyurethane (PU).

The FIG. 2 shows a plan view of the protected side S of the glazing 1 according to the FIG. 1 , wherein the part 6.1 of the frame 6 is removed above the imaginary line DD. The FIG. 2 also shows surface of the glass sheet 2.1 of the ballistic block 2 with the peripheral edge 9 and the circumferential gap 8 between the edge 9 and the horizontal part 6.2 of the frame 6 and a section 7.1 of the sealing lip. 7

If a bullet 4 on the area of the edge of the attack side A near the frame 6, 6.1 of the known, framed, transparent, bullet-resistant glazing 1 according to the FIGS. 1 and 2 the disk 2.4 splintered completely and on the protective side S of the ballistic block 2 it came to splitter outlet, so that the known glazing 1 did not meet the security requirements placed on them.

FIGS. 3, 4 and 5

The FIG. 3 shows a vertical longitudinal section through a section of a framed, transparent, bullet-resistant glazing 1 with edge reinforcement 10 according to the invention.

The ballistic block 2 of the glazing 1 according to the invention had the dimensions 0.5 mx 0.5 m, as they are customary for bombardment patterns, and was fixed in a suitable bullet-resistant steel frame 6, 6.1, 6.2, wherein the gap 8 a clearance of Was sealed 4 mm between the ballistic block 2 and the parts 6.1 by two circumferential sealing lips 7 made of a flame-retardant, rubber-elastic elastomer to the outside. At the same time, the sealing lips 7 fixed the ballistic block 2 in the steel frame 6, 6.1, 6.2.

For weight reasons, the steel frame 6 was hollow with a wall thickness of 2 mm. The inside width of the cavity was 5 mm up to the imaginary line DD and narrowed from there in the vertical, comprehensive parts 6.1 to 2 mm. The height of the parts 6.1 from the imaginary line DD was 40 mm The clear width between its two vertical, comprehensive parts 6.1 was 32.9 mm. The horizontal part 6.2 had a width of 50.9 mm.

On the attack side A of the ballistic block 2, a 5 mm thick prestressed float glass pane 2.1 was arranged and adhesively bonded to a 6 mm thick polycarbonate 2.2 using a 1.3 mm thick adhesive film 2.3. On the other side of the polycarbonate sheet 2.2 to the protective side S out two 5 mm thick tempered float glass panes 2.1 were attached with two 1.3 mm thick adhesive films 2.3.
