Portable screen

The screen 10 comprises a rigid wall panel 12 of a first weight, and a weight assembly 20 extending orthogonally from a lower edge 12b of the wall panel and being perpendicular to the principal plane of the wall panel, the weight assembly having a wheel 26c at a distal end and comprising a bulk of material that substantially counter-balances the first weight. The weight assembly may comprise a pair of elongated weighted feet, each foot having a first end affixed at the lower edge of the panel and a longitudinally opposing second end at which the wheel is mounted. The second end of each foot may have a plate 28 to which the wheel is affixed. The feet may be offset from respective corners of the wall panel by the same distance. The weight assembly may be a weighted cross beam. The wheel may be a castor wheel comprising a stopper and a stop member 24. A locking assembly may be slidably mounted on at least one of the feet between the stopper and the stop member. The wall panel may include sound-absorbing ribs 14.
