Problems solved by technology

[0011] However, a disadvantage of the flexible main panel described in WO2012 / 172256 is that its outer surface is less resistant to light (especially UV rays), or water, or severe weather
[0012] It can also be seen from observation that the decorative pattern arranged on the outer surface has poor ability to resist light, and there is a problem of color migration (migrating)
Therefore, the panel is very limited in appearance, since the outer surface of said panel cannot have any decorative pattern under conditions suitable for use (exposed to UV (ultraviolet rays), bad weather, etc.)
[0013] Furthermore, this flexible main panel is expensive to manufacture, since four layers of coating are required: for example, the flexible main panel is coated with a corresponding layer of polyurethane on its inner and outer surfaces, followed by a functional layer filled with titanium dioxide or aluminum

Embodiment Construction

[0088] figure 1The tent or shelter type equipment 1 shown in FIG. 2 comprises a sun protection device 40 comprising a roof element 2 covering the protection area 3 . The roof element 2 comprises a panel 4 having opposing outer surfaces 4a and inner surfaces 4b intended to face said protected area 3 in use. The emissivity ε3(%) of the inner surface 4b for infrared rays, especially far infrared rays is lower than the emissivity ε4(%) of the outer surface 4a for infrared rays, especially far infrared rays. The protected area 3 comprises an inner chamber 5 covered by a roof element 2 arranged at least partially at a distance (d) by an air layer 6 . In this particular example, this distance d is greater than or equal to 7 mm. Preferably, the infrared emissivity ε3(%) of the inner surface 4b is at least 20 percentage points lower than the infrared emissivity ε4(%) of the outer surface 4a.

[0089] The outer surface 4a of the panel 4 is arranged to reflect solar radiation; prefera...

Abstract

The invention provides a sun protection device (40) defining a protected area (3) from solar radiation in an external area, the device comprising at least one panel (4) having opposite outer surfaces (4a) and Inner surface (4b), said inner surface (4b) of the panel (4) comprising vertically adjacent parts in the following order: a first layer with an infrared emissivity E1 (%), a first layer with an infrared emissivity E2 (%) ), the infrared emissivity E2 (%) of the second layer is lower than the infrared emissivity E1 (%) of the first layer. The panel (4) is also arranged such that the infrared emissivity E3(%) of the inner surface (4b) is lower than the infrared emissivity E4(%) of the outer surface (4a).

Description

technical field [0001] The present invention relates to the technical field of sun protection devices defining a protected area from solar radiation from an external area, said device comprising at least one panel having opposing inner and outer surfaces, the inner surface for In use it faces said protected area, while the outer surface is intended to in use face solar radiation. Background technique [0002] The function of such a device is to provide thermal insulation for one or more users and / or substances such as food or drink placed inside the protected area, in order to improve the comfort of said users especially in summer when the weather is particularly hot, As well as limiting the extent to which said food or liquid gains or loses heat and thus heats or cools down, in order to better protect said food or liquid. [0003] In general, tents also comprise an inner chamber covered by said panels serving as roof elements, the inner chamber serving at least partially a...
