HEIGHT ADJUSTABLE PROJECTOR SCREEN SUPPORT

摘要

A projector screen support (2) is described comprising a support structure (5) with at least one guide means (6, 7) defining a length axis {8, 9) which is to be arranged essentially vertically and a screen holding support (10) for holding a projector screen (3). The screen holding support (10) is arranged movable along the length axis (8, 9), defined by said at least one guide means (6, 7). The projector screen support (2) also comprises counterbalancing means arranged to apply a force directed upwards on the screen holding support (10) in relation to the support structure (5). The counterbalancing means comprises at least two constant force springs (13) each producing a predetermined force, wherein the springs (13) are attachable/detachable in at least one end without using any tools, so that the total force from the counterbalancing means may be easily varied by attaching or detaching springs (13).
