SUN-PROTECTION ARRANGEMENT

摘要

Sun-protection arrangements in the manner of a Venetian blind are known whose vertical slats in the drawn state of the blind can be pivoted jointly about an angle of approximately 180 DEG and which can be pushed together to one side with a mutually parallel arrangement of their narrow sides for the purpose of freeing the window. …Sun-protection arrangements of this type are not able to prevent the room from heating up due to directly incident sun rays and also considerably subdue the incident daylight in the drawn state of the blind. …In order to remedy this situation, it is proposed that the slats (3) provided are plates of light-refracting material having retroreflecting properties, whose position of rotation is adjusted to the direction of incidence of the direct solar radiation (S') as a function of the movement of the sun, by means of a control device (15) in connection with a light sensor (16). The drawing and undrawing of the slat blind (2) takes place here with high precision by means of a spindle drive (5/6) which is likewise controlled by the control device (15). ……
