Abstract
A pull across screen assembly has a flexible screen member (e.g. flymesh) wound about a vertical rod positioned at one side of the opening. A line member arrangement is attached to the front of the screen member and part of the line member winds about a tapered drum which is positioned on top of rod and which rotates with rotation of the rod. The arrangement allows the screen member to be tensioned and also to be balanced as it is pulled across the opening.

1-12. (canceled)
A screen assembly comprising:
- a flexible screen having a front edge area,
- a supporting member about which the screen can be wound/unwound and which is substantially vertical and has an upper end and a lower end,
- a biasing means to create a tension in the screen,
- a drum/pulley associated with at least one end of the supporting member,
- a line member that can be wound onto and off the drum/pulley, the line member being operatively associated with the screen such that as the screen is extended, the line member is wound onto the drum/pulley, and as the screen is retracted, the line member is wound off the drum/pulley, the screen, when wound about the supporting member, having a diameter which increases as the screen material is wound about supporting member, and which decreases as the screen material is unwound from the supporting member,
- the diameter of the drum/pulley, at the position where the line member winds onto the drum/pulley or off the drum/pulley, being about the same diameter of the supporting member containing the screen, and
- the line member being operatively attached to the front edge area of the screen, the line member comprises a first part which winds onto and off the drum/pulley, a second part which is attached to the first part and which is operatively connected to the upper front edge area of the screen, and a third part which is attached to the first part and which is operatively connected to the lower front edge area of the screen.
