Definitions

• the invention relates to transparent laminates and monolithic transparencies for use in applications requiring resistance to physical penetration including physical attack and/or blast attack and/or fluid pressure applied by gas or liquid .
• banks , prisons, government buildings , computer centres and retail stores may be at risk from attempts to penetrate a window for the purposes of theft, entry, escape or vandalism.
• windows on buildings, trains, boats, aircraft and other vehicles may be subject to penetration from fluid pressure (wind or water) , mechanical impact, blast or ballistic attack.
• Transparent barriers are commonly interposed at building perimeters and/or at the perimeter of defined interior areas to control access to cash, valuables, data, personnel etc . These barriers may be permanent fixtures or be caused to take two or more positions using mechanical means.
• transparencies held in position in channels which are themselves affixed to permanent structures such as walls or floors .
• barrier As indicated, another form of barrier is a temporary barrier which is caused to change position and this may run along or in or be guided by channelways which are affixed to a permanent structure.
• the transparency allows visual contact but is resistant to the perceived threat whether ballistic and/or physical attack and/or blast . While the transparency should not be penetrated by a threat for which it is rated, it may change in appearance, degree of transparency and/or stiffness . In particular transparencies composed of glass clad polymers may sustain cracking or breakage of one or more of the glass layers and become more flexible as a result. The resulting transparency can take on significant curvature as a result of the initial attack or under the influence of continued attack.
• a transparent laminate which comprises at least two transparent layers, a transparent interlayer bonded therebetween and a stiffening member, the interlayer having at least one free surface to which the stiffening member is bonded.
• a monolithic transparency comprising a transparent polymer having a cavity adjacent an edge thereof, and a stiffening member partially located in the cavity and extending from the transparent polymer.
• the stiffening member is metal though polymers such as polycarbonate, acrylic or fibre reinforced resin may be used.
• the interlayer is a polymer or resin layer.
• the polymer layer which is preferred is manufactured under the trade mark "Noviflex” . Examples of these polymers are disclosed in US Patent nos . 4, 619,973 and 4, 663, 228. The disclosure in these patents is incorporated herein.
• resins such as acrylics, epoxys or polyesters are preferred as they exhibit the desired transparency and ability to be moulded with stiffening members without undesirable chemical or mechanical reactions.
• the transparent layers are glass .
• Suitable glass may be annealed, chemically toughened, heat strengthened or thermally toughened.
• Other transparent layers may be composed of polycarbonates or similar resistant transparent materials .
• stiffening members may be used.
• the stiffening members may extend about the periphery of the barrier.
• the stiffening members may only run across the opposing edges of the barrier.
• the portion of the interlayer extending beyond the edge of the transparent layers is provided with an opening which corresponds with an opening in the stiffening member .
• a fastening device can be passed through these openings to anchor the security barrier into any desired position.
• such openings may be counter-sunk and thus the interlayer may flow in the openings with the effect of riveting the stiffening member to the interlayer.
• the particular shape of the transparent layers or the interlayers is not critical. Typically the transparent layers are planar but could be curved or take on other two or three dimensional shapes e. g. square, circular and spherical. As such the invention does not substantially interfere with the desired architectural design of the security barrier. It has been surprisingly found that the direct contact between the stiffening member and the transparent interlayer enables fixing or alternatively reduces the potential for the security barrier to be removed from the anchorage channels by flexing.

• a security barrier 10 has a pair of transparent layers 11 and 12 separated by an interlayer 13. This arrangement defines the visual area A. Interlayer 13 extends beyond the edges of transparent layers 11 and 12 to form a peripheral skirt. A metal member 14 is placed on each side of that skirt. As more particularly seen from figure 1 the metal member 14 covers the entire periphery of the security barrier 10. Whilst metal layer 14 is shown as continuous, it can of course be made up of strips of metal.
• Anchoring apertures 15 are also provided in metal layer 14 which align with apertures 16 also formed in interlayer 13. This enables the security barrier 10 to be fixed into position with fasteners (not shown) .
• interlayer 13 is of the type disclosed in US Patent no. 4,619,973
• bonding is carried out by placing the laminate into an autoclave at a temperature of approximately 130 C and at a pressure of approximately 7 bar. This bonding has been found to be particularly resistant to separation and results in a highly stable laminate .
• metal layer 14 and transparent layers 11 or 12. are indirectly adhered by interlayer 13 flowing therebetween.
• Figures 4 and 5 depict a second embodiment of the invention .
• three interlayers 17, 18 and 19 are placed together.
• Transparent layers 20 and 21 are added to the exterior of interlayers 17 and 19.
• Interlayer 18 is of lesser width than the width of interlayers 17 and 19 and between them define cavities 22.
• Metal members 23 are placed into cavities 22. This arrangement enables the interlayers 17, 18, and 19 to bond to three separate faces on metal strip 23.
• Metal strip 23 has a flanged portion 24 in which apertures may be formed to provide additional locating and anchorage points to existing structures.
• Figures 6 to 8 depict another form of the invention particularly adapted to enable fittings to be attached to security barriers.
• the security barrier 25 comprises an interlayer 26 sandwiched between outer transparent layers 27 and 28.
• Transparent layers 27 and 28 are not continuous and each define a square area 29 into which the transparent layers 27 and 28 do not extend .
• Metal members 30 and 31 are inserted in these areas. These metal plates 30 and 31 and interlayer 26 have an aligned aperture 32 which enables fittings or other accessories to be securely fixed on either side of the security barrier or allows the barrier to be anchored from locations remote from its edge.
• the fittings can be secured to the face of a transparent panel and the stresses set up in attempting to anchor material directly to transparent layers 26 and 27, such as glass, are avoided.
• a mosaic security barrier 33 has a number of transparent panels 34.
• This laminate 33 is formed by taking an interlayer 35 and overlaying and underlaying this interlayer 35 with square transparent layers 36.
• the transparent layers 36 define channels therebetween into which metal members 37 are placed.
• a border of metal layer 38 surrounds the entire mosaic. The same arrangement is formed on the rear surface of the security laminate 33.
• metal layers in this embodiment serves to restrict the transparency of the arrangement and to improve the rigidity of the security barrier. In such a situation it would be difficult for the security barrier to be penetrated. Not only would an intruder need to penetrate through the transparent layers and the interlayer but they would also need to overcome the strength of the metal layer.
• a monolithic transparency 39 is composed of a polymer or resin sheet 40 in which an anchor 41 is embedded.
• the anchor 41 has a cylindrical rod portion 42 which is located in a cavity in sheet 40.
• Arms 43 and 44 connect to cylindrical rod portion 42 and extend from sheet 40. These arms 43 and 44 may be used to anchor the transparency 39 into any desired position.
• a monolithic transparency 45 comprises a polymer or resin sheet 46 from which an anchorage bar 47 extends.
• the anchorage bar 47 is connected to a square bar 48 embedded in sheet 46.
• the anchor can be formed into the sheet by positioning it and causing the polymer to flow around it. This causes the sheet to encase the rod or bar. As these have a width greater than the arms or anchor which extends from the sheet they are firmly held in place by the encasing sheet.
