1. Apparatus forming a base for a receiver (b) provided with a display screen, for example a computer terminal, characterised in that said apparatus comprises : a case (1) which normally bears on a bearing surface (A) and thus supports the apparatus, a flat cover (4) for supporting the receiver, mounted on the case (1) to pivot about a horizontal pin (3, 44) contained in a median plane (x-x) of the case, this pin connecting the case (1) to the cover (4), a frame (23) disposed inside the case (1) and provided with rolling or sliding means (27) to permit its displacement, this frame bearing through said means on said bearing surface (A), a lever (14) for raising together the flat cover (4) and the case (1) relative to the frame (23) which remains in contact with the bearing surface (A), while the case is raised from the bearing surface, the lever (14) being mounted on the cover (4) to pivot about a pin (19) located between its two ends and parallel to the horizontal pin (3, 44) pivotally interconnecting the cover (4) and the case (1) ; the lever (14) bearing by an end (16a) on the top (22) of the frame (23) ; the other end (13) acting as means for bringing about the raising of the cover (4) and the case (1) relative to the frame (23) so that the apparatus may be displaced by means of said rolling or sliding means (27). |
