Abstract
According to some embodiments curtain assemblies are provided having fabric curtains with brush edges that are mated to the fabric curtain. The brush edges are configured to extend laterally from the curtain to contact, for example, the side edges of the opening in which the curtain assembly is installed and remain in contact with the side edges during movement of the curtain. The brush edges can be configured to deflect along the plane of the motion of the curtain to maintain the contact between the curtain and the side edges. In some embodiments, the curtain assemblies can include optional side tracks configured to receive the brush edges, for example, to improve the connection between the brush edges and the side edges.
Claims18
A curtain assembly comprising:
- a curtain having a first and a second opposite side edges, wherein the curtain is selectably moveable vertically between an open position and a recessed position;
- a roller constructed and arranged to rotate thereby transitioning the curtain between the open position wherein the curtain is extended from the roller and the recessed position wherein the curtain is wound around the roller, the roller comprising offset portions on each end of the roller that comprise a reduced diameter;
- a roller guide configured to position the curtain proximate a covered opening;
- and
- a first and a second brush edge configured to be wound about the roller, connected to the first and the second opposite side edges of the curtain, wherein the first and second brush edges extend laterally from the first and second edge of the curtain to provide a direct connection to an installed surface at a surface of a respective side track, wherein an opposite side of the surface is directly connected to the installed surface and wherein each of the first and second brush edges comprises bristles bound into bundles, and wherein the bundles are biased to deflect along a plane defined by the curtain on which the brush edges are installed, wherein the bundles are constructed and arranged with a plurality of layers and include an offset between the bundles of bristles in adjacent layers.
A curtain assembly comprising:
- a curtain having a first and a second opposite side edge, wherein the curtain is selectably moveable vertically between an open position and a recessed position;
- a roller constructed and arranged to rotate thereby transitioning the curtain between the open position wherein the curtain is extended from the roller and the recessed position wherein the curtain is wound around the roller, the roller comprising offset portions on each end of the roller that comprise a reduced diameter;
- a roller guide configured to position the curtain proximate a covered opening;
- a first and a second brush edge configured to be wound about the roller connected to the first and the opposite side second edges of the curtain and extend the length of the first and second edges, wherein the first brush edge extend laterally from the first opposite side edge and the second brush edge extends laterally from the second opposite side edge of the curtain to provide a direct connection to an installed surface, wherein the bundles are constructed and arranged with a plurality of layers and include an offset between the bundles of bristles in adjacent layers;
- and
- wherein each of the first and second brush edges include an attachment portion joining the first and second brush edges to the curtain, wherein the first and second brush edges and respective attachment portions are constructed and arranged to wind about the roller when the curtain is transitioned to the recessed position and unwind from the roller when the curtain is transitioned to the open position.
