A MODULAR FRAME ASSEMBLY FOR DOORS, WINDOWS, VENTILATORS AND THE LIKE

Abstract

This invention relates to a medular frame assembly for deers, window ventiliators and the like. The frame holds wire mesh, not or screen in the space provided inside the frame far preventing entry of mosquitoes and files inside a housing. Two sets of parallel; members are joined together by cornar members. The parallel members have hellow channels for fixing the cornar members to connect them. oraavaa are provided in the elengated members for haveing gaskets for detachably fixing prejecting means such as next and the like. the corner members have lugs to restrist their sliding movement inside the hellow channel.

This invention relates to a modular frame assembly for doors, windows, ventilators and the like. The modular frames are particularly useful in holding inject proof meshes, nets decorative materials like furnishing fabrics and laminates* Conventionally, curtains are used for covering openings of doors, windows and ventilators. Ventilators often have glass sheets slantingly disposed to allow air and light to enter. Cities and villages are now infested with insects like flies and mosquitoes which spread diseases. People are more and more aware of keeping their dwellings free of such infection spreading insects. Curtains, though decorative do not prevent insects entering into dwelling places. Use of wire or plastic meshes to cover the open area of windows, doors and ventilators has now become very common. These nets are either nailed to the wooden door/window frame or are fixed with fixing means known in the art as velerum • Both these methods are not fully satisfactory or fool proof. Adhesive strength or capability decreases with the passage of time and the net or mesh gets fully or partially detached from the frame. quadrilateral ipteti k in batwaan wmtr Mribars L and T ahapad. hln««« •? ill* lik« «§«!• tor t to door and window frames. This invention relates to a modular frame assembly for doors, windows, ventilators and the like comprising a first and a second set of elongated parallel members intersecting each other to provide a grid having at least one quadrilateral space, at least the end portions of each of the elongated members being hollow, the said elongated members having grooves either on one or both the edges thereof corner members slidable into the hollows of the two sets of elongated members for aligning the same, the said corner members having lugs or abutments to restrict their sliding movement and to hold the said parallel members in position, grooves of the elongated members having fixing means such as gaskets for detachably holding protective elements in the quadrilateral spaces. The frame can be mounted slidably, detachably or may be opened to provide access.

It it ta be understood that obvious equipment known to persons skilled in the art are within the scope of this invention and the appended claims WE CLAIM: 1. A modular frame assembly for doors, windows, ventilators and the like comprising a first and a second set of elongated parallel members intersecting each other to provide a grid having at least one quadrilateral space, at least the end portions of each of the elongated members being hollow, the said elongated members having grooves either on one or both the edges thereof corner members slidable into the hollows of the two sets of elongated members for aligning the same, the said corner members having lugs or abutments to restrict their sliding movement and to hold the said parallel members in position, grooves of the elongated members having fixing means such as gaskets for detachably holding protective elements in the quadrilateral spaces. 2. The frame assembly as claimed in claim 1 wherein the elongated members are made of metals like anodised aluminium or durable thermoplastic resins. 3. The frame assembly as claimed in claims 1 and 2 wherein the elongated members are hollow throughout its length. 4. The frame assembly as claimed in claims 1 and 2 wherein only the end portions of the elongated members are hollow. j. inc lrame assemory as claimed in any of the above claims wherein grooves are provided on both the sides of the elongated body, the said grooves running throughout its length and the said member forming the central limb of two adjacent quadrilateral spaces. 6. The frame assembly as claimed in claims 1 to 4 wherein the elongated members have grooves on the edges forming the inner periphery of the frame assembly. 7. The frame assembly as claimed in any of the preceding claims wherein the corner members are 'L' and 'T' shaped and are made of thermo plastic resins such as polyvinyl chloride. 8. The frame assembly as claimed in claims 1 and 6 wherein the 'L' shaped corner member is slightly curved to a 'C shape. 9. The frame assembly as claimed in any of the above claims wherein the fixing means such as gasket is made of rubber or like resilient material. 10. The frame assembly as claimed in any of the above claims wherein the protecting element is selected from wire mesh, net, screen or furnishing material. 11. The frame assembly as claimed in any of the above claims having means for fixing the same to doors, windows and the like. 12. The frame assembly as claimed in claim 11 wherein the fixing means are hinges. 13. The frame assembly as claimed in any of the above claims having protecting elements such as wire mesh, net, screens and/or furnishing cloth fixed to the quadrilateral spaces provided in the grid of the said frame assembly. 14. A modular frame assembly for doors, windows, ventilators and the like substantially as herein described with reference to the accompanying drawings.
