Description

A SCREEN SYSTEM

Field of the Invention

The present invention relates to a screen system removably attachable to a molded frame fixed to a window or door or the like. In particular the present invention relates to an improved screen system which is effective for easy installing and removal.

The invention has been developed primarily for use in/with an improved screen unit for a window or door frame and will be described hereinafter with reference to this application. However, it will be appreciated that the invention is not limited to this particular field of use.

Background of the Invention

The general purpose of screens is to prevent the ingress of insects, and debris, while permitting inflow of fresh air through the interior of the home. A usual screen assembly comprises a ventilation material such as screen fabric or mesh attached to a rigid screen frame. Window screens for example, comprise a frame constructed from an extruded profile holding mesh in a tensioned condition by beading pressed into a recess in the frame profile. These screens are then fixed in place in a window or door opening.

After a period of time these screens tend to trap dust carried by the breeze coming through the window. Because these screens are usually fixed in place, this present difficulties cleaning the screen.

Numerous attempts have been made to address this problem. One attempt has been to use a hinged screen, however this approach is not cost effective. Another approach has been to secure and tension a mesh screen in open grooves formed along inside edges of the screen frame using beading strip known as "spline" and its associated fastening techniques. The open grooves are known as "spline grooves." A spline is often a wire-like, extruded rigid plastic or foam material, usually round in cross section, for example. US Pat. No. 5,039,246 (the '246 patent) shows a conventional method of securing screen to a frame member using a spline. The spline is forced into a spline groove or recess in the screen frame, with the screen/mesh sandwiched between the spline and the spline groove. The spline and trapped screen are forced into the groove, usually by hand, with the use of a roller device, including a roller.

These screens also have a number of drawbacks. For example, apart from a labor intensive and time consuming installation procedure, after repeated use the spline may become worn and does not hold the screen in place effectively, and the tension of the mesh/screen can lose tension resulting in a poor appearance and reduced

effectiveness.

Other screens have included a clipping mechanism on the window that moves between a holding and release condition such that when a screen frame is inserted in a window frame opening, the clip is open to allow insertion, and thereafter moved over the screen frame to retain the screen frame relative to the window frame. One issue with this type of mechanism however is that sealing between the screen frame and window frame is often insufficient and ineffective.

The present invention seeks to provide an improved screen system, which will overcome or substantially ameliorate at least one or more of the deficiencies of the prior art, or to at least provide an alternative. It is to be understood that, if any prior art information is referred to herein, such reference does not constitute an admission that the information forms part of the common general knowledge in the art, in Australia or any other country.
