Benefits of technology

[0033]A further possibility resides in bracing the curtain in a relatively rigid frame or in a rigid frame which is configured to be so stable that it does not deform. As a result, it is possible to prevent the occurrence of slits in the deformed state at the sides. In this case, the rigid frame can itself be mounted a

[0044]FIGS. 1-14 various forms of curtains and bar profiles for curtains of this type and also

[0045]FIG. 15 a mounting according to the invention for the curtains according to the invention.

[0046]In Figures A to E, FIG. 1 shows profiles for bars for static, internally situated applications, the profiles or the curtains not being able to be moved away. In FIG. 1A, a curtain which has a large number of bars 2A, 2B, 2C is shown. Above and below the bars 2A or 2C, further bars of this type can be situated. The bars are connected to each other via for example laser-welded metal strips 4 or also riveted. In the plane of the metal strips 4, the bars have a spacing 5.

[0047]As represented in FIG. 1, the corresponding profile, represented in cross-section as in FIG. 1B, has in total three surfaces. A first surface 11 is orientated vertically, against which, starting from the upper end thereof, a second surface 12 and, immediately extending this, a fourth surface 14 abuts. A third surface 13 e...

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...
