AI Technical Summary

Technical Problem

Current sunshade slats fail to completely shield solar rays, leading to light leakage and aesthetically unappealing designs, particularly in the closed position, with existing solutions allowing diffused light penetration and visible folded edges.

Method used

A slat design featuring a blade with a shielding area that reflects solar rays outward, combined with a connection system allowing slats to overlap seamlessly, ensuring total shading and aesthetic continuity.

Benefits of technology

The slat design effectively blocks all solar rays, providing a fully shaded internal environment while maintaining a harmonious and uniform appearance by reflecting light outward and preventing internal penetration.

Abstract

A slat (1) for sunshades (100), elongated along a longitudinal direction (L) between a first end (1A) and a second end (1B) and along a transverse direction (T), perpendicular to the longitudinal direction (L), between a first edge (1C) and a second edge (1D), and comprising an inner surface (10), an outer surface (11), opposite the inner surface (10), a connection area (ZC) extending along the transverse direction (T) from the first edge (1C) towards the second edge (1D), and including a first projection (2), rising from the inner surface (10) along a normal direction (N), respectively perpendicular to the longitudinal direction (L) and to the transverse direction (T), and a second projection (3), rising from the inner surface (10) along the normal direction (N) and spaced apart from the first projection (2) along the transverse direction (T), a shielding area (ZS), extending along the transverse direction (T) from the second edge (1D) up to the connection area (ZC), comprising a blade (4) rising from the outer surface (11), opposite the inner surface (10), along a shielding direction (DS) having at least one component along the normal direction (N).
