WINDOW GUARD FRAME SYSTEM

FIELD OF INVENTION The present invention relates to screens for windows and window frames of a building or house. The present invention has particular but not exclusive application for windows in single, multi level, homes, buildings, dwellings or apartments.

BACKGROUND OF THE INVENTION Windows in apartments and homes are often left partially open to allow the circulation of fresh air while the occupants are home, or in particular, when they are out or away from the building. To prevent the entry of insects the window usually has a flyscreen extending across the opening. Unfortunately rain can enter and cause damage to the flooring, carpet, fixtures, furniture, finishes or items within the building. To counter rain and storm damage, window guards were developed for placement on the outside of the windows. By way of example, AU2005201900 describes a weather cover for a window. The weather cover is aerodynamically shaped and can be mounted to the outside of a window by the use of double sided tape, adhesives or fasteners. A disadvantage of the weather cover described in AU2005201900 is the mounting of the cover to windows that are not accessible from the outside of the building such as multi level buildings. The weather guard if not securely mounted can also be blown away during a storm or in high winds.

OBJECT OF THE INVENTION It is an object of the present invention to provide a window guard system that allows a window to remain open while preventing the entry of rain thereby overcoming at least in part one or more of the aforementioned problems.

SUMMARY OF THE INVENTION The present invention was developed to securely install a window guard by altering the flyscreen frame to include a channel for the mounting of a window guard using stoppers or spline to prevent movement within the channel. The invention was developed with trial and experimentation. The invention was developed to involve the cooperation between the various components to form a mounted window guard arrangement. In one aspect the present invention broadly resides in a window guard frame system including a frame mountable within the window jamb; a window guard insertable within the frame; wherein the position of the window guard within the frame is secured by the placement of one or more stoppers within a frame channel to prevent movement of the window guard along the channel. o Preferably the window guard frame assembly includes a flyscreen insertable within the frame. Preferably the one or more stoppers includes an elongate spline. More preferably the elongate spline extends from the window guard to the end of the frame section. In a further embodiment the spline extends around the frame channel between the ends of the inserted window guard. Preferably the spline is of suitable cross-section and thickness to occupy the space within the frame channel to prevent the nesting of insects therein. Preferably all open channels are closed with the spline to occupy the space within the channels to prevent the occupation by insects and formation of their nests and accumulation of dust and particulates. As an option, the window guards can have protruding bumps that serve as self-locking bumps to locate and or assist in fixing the guards in a position within the frame. Preferably the flyscreen frame is a substantially rectangular shaped frame formed from joining four separate framing members. Each section preferably has the same cross-section profile. Each of said framing member is preferably an elongate section which in cross-section has a substantially rectangular portion with an I-shaped flange extending from a narrow side wall of the rectangular portion and said I-shaped flange and an opposing first wall forms a second longitudinal recess for fitting the window guard. The elongate section preferably has an L-shaped flange. The L-shaped flange and the narrow side wall of the rectangular portion preferably forms a first longitudinal recess adapted to fit a flyscreen mesh and a spline. The first longitudinal recess is preferably wider than said second longitudinal recess.

The opposing first wall is preferably a section of the L-shaped flange. The elongate section is preferably of constant cross-section and indefinite length. The first longitudinal recess preferably has an opening on a wide side of the rectangular section. The elongate section is preferably substantially rectangular in cross-section with an L-shaped flange extending from a narrower side to form the first longitudinal recess that opens on a wide side of the elongate section. Preferably the elongate section is a substantially rectangular section with the o second longitudinal recess having an opening on a narrower side of the rectangular section. Preferably there is an I-shaped flange that is positioned adjacent to the L shaped flange to form a U-shaped recess being the second longitudinal recess. In another embodiment there is preferably a third longitudinal recess for fitting a security mesh wherein the elongate section is substantially rectangular in cross section with the second and third longitudinal recesses adjacent each other and each opening along the narrow side of the elongate section, said first recess opening along the wide side of the elongate member. The second and third recesses are preferably separated by a common wall. Preferably each longitudinal recess has one or more longitudinal internal ribs for retaining an insert within the recess. The window guard is preferably positionable within the second longitudinal recess serving to cover a window opening but substantially preventing the entry of rain while allowing the circulation of air. A frame assembly including a plurality of the framing members claimed from any one of the preceding claims wherein said framing members are assembled to form a frame and a fly screen mesh is positionable within the first longitudinal recess and a weather cover is insertable within the second longitudinal recess. The flyscreen is preferably a standard plastic-coated mesh. The window guard is preferably an aerodynamically shaped to withstand high winds. Preferably the window guard is elongate with a curved section extending from a leading edge and transversely across the width of the guard in a substantially continuous curve and a peripheral flange extending around the edge of the window guard except for the leading edge; wherein said leading edge is adjacent a variable gap that allows air to pass when the window guard is mounted to the frame. Preferably the window guard in transverse cross-section has a shallow convex shape. In a further aspect the invention broadly resides in a window guard assembly including a plurality of framing members joinable to form a frame, wherein each of the framing members is an elongate section that is substantially rectangular in cross section with a first longitudinal recess opening along a wide side of the elongate o section and a second longitudinal recess opening along a narrow side of the elongate section; a window guard mountable within the second longitudinal recess of the frame; and a stopper or spline positionable in the second longitudinal recess abutting the mounted window guard to prevent movement of the window guard along the second recess. Preferably the window guard assembly includes a flyscreen mesh insertable within the frame within the first longitudinal recess. Preferably the window guard assembly includes a plurality of joined framing members; a fly screen mesh positionable within the first longitudinal recess; and a window guard mountable within the second longitudinal recess. The features described with respect to one aspect also apply where applicable to all other aspects of the invention. Furthermore different combinations of described features are herein described and claimed even when not expressly stated.

BRIEF DESCRIPTION OF THE DRAWINGS In order that the present invention can be more readily understood reference will now be made to the accompanying drawings which illustrate a preferred embodiment of the invention and wherein: Figure 1 is a diagrammatic view of a window of a building where the window guard assembly is fitted to the window;

Figure 2 is a diagrammatic view of the window guard assembly from an outside (or front) position; Figure 3 is a diagrammatic view of the window guard view from the inside (or rear) position; Figure 4 is an exploded view of the window guard assembly Figure 5 is a partial view of the window guard assembly Figure 6 is a diagrammatic view of the frame for the window guard assembly; and Figure 7 and 8 are diagrammatic views of the front and rear views of the window guard respectively.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT With reference to the figure 1 to 8 there is shown a building 10 with a window 11 with the window guard assembly 12 fitted to the window 11. The window guard assembly 12 includes a frame 14 a window guard 15 and a flyscreen 16. The window guard assembly 12 is mounted to substantially U-shaped channel members 17 surrounding the periphery of the window jamb 18. The window guard assembly 12 is mounted on the outside of the window glass pane 19. The window glass pane 19 can be partially opened but no wider than the width of the window guard 15 and not beyond the leading edge 21 of the window guard 15. The edge 22 of the window glass pane 19 is open sufficiently to allow air to enter through the window 11 via the window guard 15. The flyscreen 16 fitted to the frame 14 filters the air passing through the window 11. The window guard 15 is substantially convex in shape having a leading edge 21 on one side and a peripheral flange 24 on the other three sides. These sides can include a raised portion acting as a locating or self-locking bump. The convex portion 23 of the window guard 15 forms a continuous curve over the majority of the guard 15. The leading edge 21 does not extend to the plane of the peripheral flanges 24. When fitted, there is a gap 26 formed between the leading edge 21 and the adjacent flyscreen 16 allowing the passage of air. The window guard 15 is fitted on one side of the frame 14 in a recess 28. The window guard 15 is held in position by a rubber or plastic spline 29 fitted into the recess 28 to occupy the space of the recess 28 and abut the flange on either side of the leading edge 21. Alternatively or in conjunction the window guard is held in position by the self-locking bumps. The spline 28 also serves to prevent the accumulation of dust and particulates and stop insects from forming nests in the recess 28. The frame 14 has a second recess 30 for the fitting of the flyscreen 16. The recess 30 is adjacent recess 28 but open inwardly and at approximately 90 degrees relative to the opening of the recess 28. The flyscreen 16 is held in position by a spline 31 that is fitted within the recess 30 clamping the flyscreen 16 within the recess 30. The window guard system involves forming the window guard assembly 12 and fitting or inserting the formed assembly 12 to or into the substantially U-shaped channel members 17 surrounding the periphery of the window frame 18. As a preformed assembly 12, it provides the advantage that it can be easily installed and not rely on using fasteners, adhesives or double sided tape. Furthermore the window guard assembly 12 can be easily removed for servicing.

VARIATIONS It will of course be realised that while the foregoing has been given by way of illustrative example of this invention, all such and other modifications and variations thereto as would be apparent to persons skilled in the art are deemed to fall within the broad scope and ambit of this invention as is herein set forth. Throughout the description and claims of this specification the word "comprise" and variations of that word such as "comprises" and "comprising", are not intended to exclude other additives, components, integers or steps.
