发明名称 Portable screen assembly for use with a projector
摘要 A portable screen assembly for use with a projector has a housing made up of a lower casing and an upper casing pivotally mounted on the lower casing to open or close the lower casing. The housing accommodates a roll rotatably mounted on the lower casing, a screen wound around the roll, a hanger bar to which one side of the screen is connected, and two extension robe assemblies having respective first ends pivotally mounted on the lower casing for movement between folded-down positions and erected positions generally perpendicular to each other. The hanger bar extends parallel to the roll in a spaced relationship when accommodated within the housing, while the two extension robe assemblies extend, when in the folded-down positions, in line with each other in a direction parallel to the roll and in a spaced relationship thereto. A bar clip is mounted on a second end of each of the extension robe assemblies. When the screen assembly is in use, each of the extension robe assemblies is moved to and extended at the erected position, and the hanger bar is placed on and held by the bar clip so that the screen is stretched out between the hanger bar and the roll, with the extension tube assemblies positioned on both sides of the screen.
