ABSTRACT:
The apparatus has several carrying bars which can be spread in radial manner from a central headpiece (2) and several shielding screen elements (17, 18), which are in each case fixed between two carrying bars. The multipart construction of the carrying bars from longitudinally displaceable, interengaging bar elements (4, 5) makes it possible to slide screen elements (17, 18) over one another, so that the apparatus, when in use, can provide different shielding surface sizes starting from a compact, slid together and collapsed form. By sliding over one another limited light-transmitting screen elements, it is possible to individually adjust the shielding action.
