Abstract
The present invention relates generally to a screen assembly that can be used in a window or door cavity, or any other area which may benefit from the assembly and which contains a flexible sheet like member (for instance an insect screen) wound about substantially vertical rod (for example), which can be pulled across the window or door cavity such that the screen extends and retracts in a horizontal direction and particularly to a system and method allowing more straightforward installation on site, quickly and easily.
Claims46
A pull across roll up screen assembly comprising:
- a. at least one flexible screen having a stile located at a front edge area of the flexible screen
- b. a substantially vertical supporting member about which the flexible screen can be wound/unwound and having an upper end and a lower end,
- c. at least one biasing device associated with the stile to create a tension in the flexible screen,
- d. at least one drum associated with the supporting member,
- e. a line member that can be wound onto and off the drum, the line member being operatively associated with the stile such that as the flexible screen is extended, the line member is wound onto the drum, and as the flexible screen is retracted, the line member is wound off the drum, the line member being operatively associated with the at least one biasing device using an attachment assembly including:
- i. a line connection device relative to which a portion of the line member is connectable;
- ii. a slide block operatively associated with the at least one biasing device and having a tensioning assembly;
- and
- iii. an elongate connector mounted relative to the line connection device and configured for selective engagement with the tensioning assembly to tension the line member and thereby tension the flexible screen.

An attachment assembly for a pull across roll up screen assembly, the attachment assembly comprising:
- a line connection device relative to which a portion of a line member of the screen assembly is connectable;
- a slide block operatively associated with at least one biasing device of the screen assembly and having a tensioning assembly;
- and
- an elongate connector mounted relative to the line connection device and configured for selective engagement with the tensioning assembly to tension the line member and thereby tension at least one flexible screen of the screen assembly.

A method for assembling a pull across roll up screen assembly comprising:
- a. a flexible screen having a stile located at a front edge area of the flexible screen
- b. a substantially vertical supporting member about which the flexible screen can be wound/unwound and having an upper end and a lower end,
- c. at least one biasing device associated with the stile to create a tension in the flexible screen,
- d. at least one drum associated with the supporting member,
- e. a line member that can be wound onto and off the drum, the line member being operatively associated with the stile such that as the flexible screen is extended, the line member is wound onto the drum, and as the flexible screen is retracted, the line member is wound off the drum, the line member being operatively associated with the at least one biasing device using an attachment assembly including:
- i. a line connection device relative to which a portion of the line member is connectable;
- ii. a slide block operatively associated with the at least one biasing device and having a tensioning assembly;
- and
- iii. an elongate connector mounted relative to the line connection device and configured for selective engagement with the tensioning assembly to tension the line member and thereby tension the flexible screen;
- the method including the steps of pre-tensioning the line member before attachment to the line connection device, attaching the line member to the line connection device, engaging the elongate connector with the tensioning assembly of the slide block to take up any slack in the line member, working the flexible screen to wind and unwind the line member a number of times and adjusting the final tension of the line member by moving the elongate connector relative to the tensioning assembly of the slide block if necessary.
