| 摘要 |
<p>The invention relates to a decorative structure which is characterised in that it consists of a frame that is formed by cylindrical profiles (1 to 4) comprising two diametrically-opposed grooves (15, 16) which are formed by essentially-cylindrical channels that open onto the surface of the profile by means of a slot which is narrower than the internal cross-section of the channels. According to the invention, the profiles (1 to 4) are assembled using tensioning elements consisting of a plate (6 to 9) comprising converging lateral projections (17, 18) on two sides thereof, the cross-section of said projections being complementary to that of the grooves, and an extendible element (10 to 13) which is disposed between the lateral projections. The inventive structure also comprises a screen (5) which is equipped with a peripheral strip (27) having a cross-section that essentially corresponds to that of the channel (15).</p> |
