A roll-up wall system including a frame having a longitudinal axis, a first roller disposed in the frame, a second roller disposed in the frame, and a tube disposed in the frame. A screen may be connected to the tube. The screen may be supported by the first roller and the second roller. Further, the screen may be movable between a first configuration and a second configuration. In the first configuration, the screen is rolled around the tube which is spaced a first distance from the first roller. In the second configuration, the screen forms a barrier adjacent the frame, and the tube is spaced a second distance from the first roller. The second distance may be less than the first distance. Also, the roll-up wall system may be an acoustic barrier which achieves a Sound Transmission Class rating ranging from approximately 31 STC to approximately 53 STC.

Modular roll-up wall system

Apparatus, article of manufacture and method for designing a jewelry setting that comprise displaying on a display a plurality of components. Each component corresponds to a section of a jewelry setting. A selection of at least one component that corresponds to a first section of the jewelry setting is received. An electronic template of the jewelry setting is generated. The electronic image comprises the at least one selected component. The electronic template is transmitted to a remote device.

The present invention relates to roll-up wall and acoustic barrier system () which may include an elongated member (). The elongated member may include a front wall (), a rear wall () spaced from the front wall, a bottom wall (), a first top wall () adjacent the front wall, a second top wall () adjacent the rear wall, and a channel () between the first top wall and the second top wall. The channel may comprise a first side wall (), a second side wall (), a first ledge (), and a second ledge (). The first and second ledges may define a slot () between the first side wall and the second side wall. The elongated member may further comprise a conduit () disposed between the front wall () and the rear wall () that is connected to the channel via the slot.

The present invention relates to a track for connecting a pair of flexible membrane barrier segments in a retractable wall system. The track may include an elongated member having a first longitudinal axis and a first cross-sectional profile perpendicular to the first longitudinal axis. The track may include a base surface and a latching surface. The latching surface may be spaced from the base surface and may include a first groove aligned with the first longitudinal axis, a second groove spaced from the first groove, a projecting element located between the first groove and the second groove, the projecting element being aligned with the first longitudinal axis. The latching surface may further include a hooking element spaced from the projecting element, and a guide surface disposed between the projecting element and the hooking element.
