Abstract
The present invention is directed to a roll-up, flexible, sound-attenuating wall system. More particularly, this invention relates to a retractable wall system and its components which may be used to divide existing larger spaces into smaller spaces with sound-attenuating barriers. In each unit the flexible, sound-attenuating wall is attached to a receiver tube which, when turned on its axis, deploys or retracts the flexible, sound-attenuating wall. The flexible, sound-attenuating wall is guided by a guide roller to intersect with other flexible, sound-attenuating walls at various angles. The receiver tube and guide roller are attached at either end to independent support brackets. This invention discloses a plurality of interlocking connector systems for connecting a plurality of flexible, sound-attenuating walls at various angles. Further, this invention discloses a winding mechanism disposed in and attached to receiver tube which turns the receiver tube on its longitudinal axis to deploy or retract the flexible, sound-attenuating wall.
