Abstract
Abstract The reflector arrangement consists of a several plate-shaped elements (12) having abutting edges and being placed to meet in one plane. The plate-shaped elements (12) are held together by a mounting (10) the front plate (13) of which partly covers the elements (12). The front surface of plate (13) is also reflective. A clamping rail (15) is secured to the plate (13) via a clamping hinge. The reflector arrangement can be used in connection with one of the plate-shaped elements (12) or with four plate-shaped elements (12) in total, but it can be also utilized only with the use of the front plate (13) of the mounting (10) as a reflector and without the plate-shaped elements (12). The elements (12) can be piled thus permitting to fold the reflector screen (11) without the formation of creases or breaks.
