Splinter protection with optical and thermal functionality

Abstract

The present invention relates to a curtain which is suitable as shatter protection and has optical and thermal functionality. Curtains of this type are required in particular in order to protect buildings for example during terrorist attacks. This fundamentally relates to any type of building, in particular however, office buildings with large areas of glass.The fundamental concept of the present invention is to provide curtains which absorb the huge amount of energy, for example of an explosion, however also irreversible damage of the curtain being able to be accepted. It is thereby essential that the curtain absorbs the acting energy and inter alia prevents any possibly occurring fragments of a glass façade being thrown into the room and being able to injure people there. The curtain is configured for this purpose as an internally situated or externally situated curtain, advantageously as a slatted curtain / shutter or even as a roller blind.

Description

PRIORITY INFORMATION[0001]The present application is a continuation of PCT Application No. PCT / EP2007 / 001045 filed on Feb. 7, 2007 that claims priority to German Application No. DE 102006005509.8, filed on Feb. 7, 2006. Both applications are incorporated by reference herein in their entireties.BACKGROUND OF THE INVENTION[0002]The present invention relates to a curtain which is suitable as shatter protection and has optical and thermal functionality.[0003]Curtains of this type are required in particular in order for example to protect buildings during terrorist attacks. They are required in all sorts of buildings but in particular in office buildings with large areas of glass.[0004]Buildings with large areas of glass, in particular office buildings, are subject to particular dangers during terrorist attacks or also basically during explosion occurrences. The reason is that normal sun protection systems are not stable enough, in particular non-buckling, in order to protect the areas o...

AI Technical Summary

Benefits of technology

[0010]If it is movable and weather-resistant, such a curtain can also be used as an externally situated, stable, in particular wind-stable, curtain. This makes it possible then for the first time, even in multi-story buildings over 100 metres in height, to deploy an externally situated sun protection, which has not been possible to date because of the wind loading. Such an externally situated sun protection in high office buildings would offer a large energy saving potential in the trend of the moment for whole glass façades. The curtain according to the invention is thus already financially viable as a result of savings in operating costs and a smaller air-conditioning plant. Also less ventilation and air-conditioning technology has an effect on the profitability of the curtain according to the invention via a smaller spatial requirement for shafts and channels and a correspondingly greater rentable area. In combination with energy saving regulations, for example of the European Union, the curtain according to the invention makes possible a small revolution in multi-storey construction with complete glass façades.

[0037]As a further technical measure for increasing the stability of the slats in the case of a shutter slat, such as e.g. the C-slat, the Z-slat, slats which are known under the name Hüppelux Genius, Retroflex, Retrolux-O, Retrolux-U or Ganzmetallstore (of the company Hüppebaumann), these are glued entirely or partially with Kevlar or similar and are not guided with guide cords but with looped cords. These distort less easily. Looped cords of this type should be stable (e.g. metal threads, Kevlar, a fibre composite and the like). The lower rail here should then also be fixed in order that the curtain is securely tensioned.

Problems solved by technology

This makes it possible then for the first time, even in multi-story buildings over 100 metres in height, to deploy an externally situated sun protection, which has not been possible to date because of the wind loading.
