Temporary masking ceiling

Abstract: The ceiling comprises two identical, superposed sheets (NS, NI), each forming a pattern with polygonal openings, a top sheet (NS) and a bottom sheet (NI), superposed, linked by a curtain of multi-stranded joining yarns (10) along the sides (C1-C6) of the openings (Oi) in order to suspend the bottom sheet (NI) on the top sheet (NS) forming open, vertical cells (Ai). Temporary masking ceiling formed by a textile fabric provided with transverse orifices, joined to form open, tubular cavities. (end of abstract)

FIELD OF THE INVENTION

This invention relates to a temporary masking ceiling formed by a textile fabric with transverse orifices joined to form open tubular cavities.

PRIOR ART

For the most part, temporary, commercial or cultural exhibitions are set up in specialised, very tall halls of an industrial nature under beams, because they must be able to accommodate a whole variety of products for human activity. Their industrial appearance is accentuated by fixed lighting means, always located very high up, which means that they glare and are thus unsuitable for exhibiting refined objects of human size, such as consumer goods or cultural items. Such exhibitions are the most frequent type.

It is therefore often necessary to transform the appearance of these halls in order to adapt them aesthetically and sometimes technically to the nature of the exhibition in question. Specialised architects are called in to design them and stand or exhibition fitters set them up.

These professionals use techniques which are associated with building work but very specialised due to the specific conditions of how they are used. Of these techniques, those involving temporary masking ceilings are the most important and the most complex.

These ceilings comprising flat sheets which are suspended and tautened contribute to the three actions of:

- masking the hall roofs and their industrial equipment from the view of visitors, thereby eliminating all unsightly views,
- enabling aesthetic exhibition spaces to be created, in tune with both the dimensions and the nature of the objects exhibited,
- enabling lighting systems to be created which are in tune with the exhibited products. This operation involves either neutralising the glaring effects of the fixed lighting systems by diffusing them or integrating new lighting systems which neutralise and/or diffuse the fixed lighting systems.

As a result of these operations, the ceilings mask and eclipse whatever fixed, artificial or natural lighting sources there might be in the halls to varying degrees.

In addition to having to satisfy these basic functions at the installation site, these ceilings must also conform to safety regulations as a matter of course, i.e.:

- be sufficiently fire resistant in the event of potential fires,
