发明名称 Foldaway projector table with adjustable levelling - has three plates in Z-formation with adjustment leg slotting in one of series of ridges
摘要 <p>The projector table comprises three collapsible plates (2, 3, 4) which are hinged together in Z-formation. The middle plate (3) has two displaceable supports (8, 9) so that a stepless adjustment of the height and angle of the top plate supporting the projector can be achieved. The whole assembly folds away flat and the base (2) of the table can form the lid of a film slide box. The lower edges (16) of the support elements (8, 9) can engage in suitably ribbed areas (10) of the base and tabletop plates so as to be securely held in position once the level position has been reached.</p>
