Description

AUSTRALIA Patents Act 1990 COMPLETE SPECIFICATION FOR A STANDARD PATENT ORIGINAL Name of Applicant: MELFORD HOLDINGS PTY LTD Actual Inventor: Jackie TONG Address for Service: FRASER OLD & SOHN Patent Attorneys PO Box 560 MILSONS POINT NSW 1565 Attorney Code: FO Invention Title: Framing System Associated Provisional Application No.: 2007 905 625 Dated 15 October 2007 The following statement is a full description of this invention including the best method of performing it known to us. 2946A-AU 1 Framing System Field of the Invention The present invention relates to framing and, in particular, to a frame formed from a continuous length of strip material. 5 The invention has been developed primarily with respect to door, window, hatch or access frames and will be described hereinafter with reference to these applications. However, it will be appreciated that the invention is not limited to these particular fields of use and is also applicable to other applications. 10 Background of the Invention Metal door and window frames, for example, are widely used in both commercial and domestic construction applications. Typically, a door frame is a rectangular three sided frame where each side is formed from a corresponding elongated length of 15 framing member interconnected to the corresponding end of an adjacent length. In a window frame (and some door frames), four such lengths are interconnected at adjacent ends to form a closed square or closed rectangle. It is typical that the ends of adjacent lengths of a frame are rigidly or permanently 20 connected together by means of a weld, a screw or other fastener or by means of interleaving the ends of the adjacent lengths. In the case of interleaving the ends, a corner junction is formed whereby a tab projecting from one or both adjacent length ends engage with each other and/or a slot in the end of the adjacent length. 25 In the case of a door frame, a three sided rectangular frame is typically formed with a bottom end being open (i.e. missing a base member). As with the window or other type of metal frame, the frame sidewalls are configured to be attached to a support frame such as a stud, single or double brick wall, or concrete wall by, for example, means of bolts or other fasteners or means such as brick ties or stud frame clips. The 30 lower end of each frame sidewall at the open end of the door frame typically includes a tab that is welded, riveted or otherwise fastened to the frame as a separate element which is itself secured to the floor to secure the lower end of the door frame. 2946A-AU 2 Not only is it the case that with conventional steel door, window or other frames that each of the frame sidewalls needs to be assembled from individual lengths, those lengths must be accurately formed. Furthermore, additional manufacturing or installation is required in order to put securing tabs on a door frame whether this be by 5 welding, riveting or other means. Yet further, the use of a welder or interleaving tab arrangement to connect the side lengths of the door frame at an upper end, or the window frame at each adjacent corner for structural strength adds to the cost of manufacture accordingly. 10 Genesis of the Invention The genesis of the present invention is a desire to provide a metal frame formed from a continuous length of strip material which overcomes or substantially ameliorates one or more of the disadvantages of the prior art, or to provide a useful alternative. 15 Summary of the Invention According to a first aspect of the present invention there is provided a frame comprising a continuous predetermined length of blank strip material having one, or two or more longitudinally spaced apart, folding apertures wherein said blank strip is formed into a predetermined cross-sectional shape and is folded about said folding 20 apertures. According to a second aspect of the present invention there is provided a blank for a frame, said blank comprising a continuous predetermined length of blank strip material having one, or two or more longitudinally spaced apart, folding apertures and 25 being formed into a predetermined cross-sectional shape. According to a third aspect of the present invention there is provided a method of forming a frame, said method comprising the steps of: providing a continuous predetermined length of blank strip material; 30 disposing one, or two or more longitudinally spaced apart, folding apertures through said blank strip material; and folding said blank strip about said folding apertures to form said frame. 2946A-AI 3 According to another aspect of the present invention there is provided a method of forming a blank for a frame, said method comprising the steps of: providing a continuous predetermined length of blank strip material; disposing one, or two or more longitudinally spaced apart, folding apertures 5 through said blank strip material; and forming said blank strip material to a predetermined cross-sectional shape. Preferably, the blank strip is formed into the predetermined cross-sectional shape by means of roll forming. Each folding aperture can be created or disposed in the strip 10 before or after roll forming. It can therefore be seen that there is at least advantageously provided a frame having two or more sides which is formed from a continuous or unitary length of blank strip material. Furthermore, it will be appreciated that floor mounting tabs can be 15 integrally formed with the blank strip material.

It will be appreciated that like reference numerals are used throughout the description of the preferred embodiments to denote like components 20 unless indicated otherwise. Shown in Figs. 1 to 11 is a door frame 1 according to a preferred embodiment. Fig. 1 is a side view of a door frame 1 formed from a continuous predetermined length of blank strip material 3. Fig. 2 is a top view of the door frame blank of Fig. 1 25 The door frame includes a pair of door frame legs 7 and 9. A head 11 extends intermediate an upper end 12 and 14 of each leg 7 and 9 respectively. The distance the legs 7 and 9 are apart defines a door frame width and the legs 7 and 9 can be any preferred height. 30 Referring to Fig. 3, there is shown a side view of a continuous blank metal strip material 3 having a predetermined length which forms the frame 1. The strip material 3 includes two folding apertures 5 which are spaced apart longitudinally along the length of the strip material 3. The folding apertures 5 are configured to allow the strip 2946A-AU 5 material 3 to be folded about hinge points 6 formed by the strip material 3 intermediate the folding aperture and strip edges. Fig. 4 is a side view of the strip material 3 being folded about the hinge points 6 of the 5 folding apertures 5. A top view of the shape of the aperture 5 of the strip material 3 is shown in Fig. 5. Along opposite faces of the aperture are disposed interleaving tab members 13. The tabs can be any preferred shape and their function is described further below with reference to Figs. 8 and 9 particularly. 10 The continuous length of strip material 3 is roll formed into a pre-determined cross sectional shape. Fig. 6 is an end view of the strip material 3 once it has been formed. Fig. 7 is a perspective view of a portion of the strip material 3 once it has been formed into the predetermined shape. Fig. 8 is a top view of the strip material 3 formed into the predetermined cross-sectional shape. 15 The strip material 3 is formed into a shape expedient for use as a door frame. In the embodiment shown, the shape provides an outer wall lip 15 extending from a frame outer wall 17. Extending parallel with the outer wall lip 15 at the other end of the outer wall 17 is a mounting face 19. The mounting face 19 can be configured to 20 receive a strike plate or hinge, for example. A projection face 23 extends a predetermined distance from the mounting face 19. A door jamb 21 is provided in the strip material 3 intermediate the mounting face 19 and the projection face 23. Fig. 7 illustrates a perspective view of the strip material 3 as formed with the hinge 25 points 6 about the folding aperture 5 substantially disposed in a portion of the outer wall lip 15. Fig. 4 is a side view of the door frame 1 being folded about the folding apertures 5 to provide the door frame of Figs. 1 and 2. It can be seen that the legs 7 and 9 are each 30 pivoted about the hinge point 6 of the folding apertures 5 so that the legs are substantially perpendicular to the door frame head 11. The blank strip material 3 is preferably formed into the predetermined cross-sectional shape by means of roll forming, however, any other forming means such as brake pressing or the like can also be employed. 2946A-AU 6 Once the legs have been folded about the folding apertures 5, the outer wall 17, mounting face 19, jamb 21, projection face 23 on each side of the aperture are moved adjacent one another, and preferably abut one another to form a corner. In its way, the 5 folded strip material 3 is moved so that the cross sections of the material 3 meet or substantially meet once folded about the hinge point 6. Fig. 9 shows a perspective view of a top of the door frame 1 in the folded configuration and Fig. 10 is a top view of a corner of the door frame 1 the folding 10 edge adjacent the top 12 of the first leg 7. Once the legs are pivoted about the hinge points 6, the opposite folding aperture edges are adjacent each other. These edges can support adjacent edges. The interleaving tabs 13 are folded over adjacent portions of the strip material 3 so as to secure the fold. It will be appreciated that any preferred tab shape, number of tabs or tab formation can be used. 15 Referring to Fig. 11, there is shown a lower portion 16 of the first leg 7 in perspective view. Where the lower end 16 of the leg 7 is to be mounted to a floor or bottom cross frame, a tab 25 is formed in the strip material 2 and bent substantially perpendicular to receive a fastener therethrough. In this way, once the door frame has been positioned 20 the tabs 25 are bent outwardly from the strip at the lower end of the door frame and this is simply secured to the floor. Of course, any preferred number of tabs 25 and any preferred shape thereof can be employed as desired. Or course, the tab 25 can be absent if desired. 25 It can therefore be seen that there is advantageously provided a door frame 1 formed from a continuous or unitary length of blank metal strip material 3 which does not require the frame edges 7, 9 and 11 to be separately secured together. Furthermore, the door frame 1 can advantageously be roll formed from the blank strip material 3 or, if desired brake formed, or formed by other preferred folding means. Yet further, it 30 can be seen that the door frame 1 advantageously removes the need for welding corners of the frame together as the strip material each side of the folding aperture when folded can act to abut each other for structural rigidity. 2946A-AU Referring to Figs. 12 and 13, there is shown a frame 50 according to another preferred embodiment of the invention. The frame 50 is formed from the same blank strip material 3 having the same cross sectional shape and same shaped folding apertures. However, three folding apertures are provided so that the blank strip once folded 5 about each folding aperture 5 meets at its ends and forms a closed rectangular loop. As best shown in Fig. 12 in top view, the closed frame 50 includes a foot 10 extending intermediate a lower end of the legs 7 and 9. In the embodiment shown, at one corner 40 the two ends of the strip material 3 are attached together by folding interleaving 10 tabs 13. It will be appreciated that the closed loop frame 50 of this embodiment can be used as a window frame, access frame, hatch frame, four sided door frame or any other desired use. Figs. 14 to 17 show a portion of a length of blank strip material 300 for a frame 15 according to another preferred embodiment of the invention. In this embodiment, the folding aperture 5 is shaped differently to that of the first preferred embodiment, however, the predetermined formed cross sectional shape is substantially the same. Most significantly in this embodiment, the no interleaving tabs 13 are provided. As best shown in Figs. 16 and 17, once the strip material 3 is folded about the folding 20 apertures 5, a weld can be used to secure the folded corner together if desired, or the adjacent edges of the folding apertures simply support themselves after installation to studs, for example. Turning now to Fig. 18, there is shown a plurality of preferred cross sectional shapes 25 for forming the blank strip material 3. It will be appreciated that any preferred cross sectional frame shape can be provided depending on the desired application. Other applications can include sliding door or window frames, or built-in wardrobe frames. It will be appreciated that the shape of the folding aperture 5 can be any as preferred 30 to allow edges of the folding aperture to be moved adjacent each other or abut one another once folded about the folding apertures 5. The apertures can be formed by any preferred means such as pressing, punching or cutting. Further, the apertures 5 can be formed about a periphery by a line(s) of weakening for removal when desired. 2946A-AU It will also be appreciated that any preferred interleaving tab engagement arrangement can be employed. In addition to folding tabs, slots may be disposed in the blank strip material (not illustrated) to receive tabs or, as shown in the embodiment of Figs. 14 to 17, the tabs can be removed all together. 5 Although not illustrated, it will be appreciated that the folding apertures 5 in the blank strip material 3 can be formed from one, or two or more apertures disposed adjacent such that one, two or more hinge points 6 are provided in the folding aperture 5. The shapes and number of folding apertures 5 can be any preferred such that edges of the 10 folding apertures of the strip material, or a pre-determined portion thereof, are moved adjacent to, or abut, once folded about the hinge point(s) 6. Furthermore, it will be appreciated that the blank strip material 3 can include any preferred number of folding apertures to provide a frame having a preferred number 15 of sides. For example, the blank strip material 3 may include only a single folding aperture 5 and once folded thereabout provide a pair of sloped legs for a triangular door frame. If two folding apertures 5 are provided, a triangular closed loop frame (not illustrated) can be provided. Likewise, a polygonal frame, open or closed loop, can be formed by providing a plurality of apertures being one less than the number of 20 frame members (for example, head and various legs). For example, a closed loop pentagonal frame can be formed from a blank strip material having four folding apertures and an open pentagonal frame can be formed from a blank strip material having three folding apertures. 25 The foregoing describes only some embodiments of the present invention and modifications, obvious to those skilled in the art, can be made thereto without departing from the scope of the present invention. The term "comprising" (and its grammatical variations) as used herein is used in the 30 inclusive sense of "including" or "having" and not in the exclusive sense of "consisting only of'. 2946A-AU
