Description: Description METAL SECTION MEMBER ASSEMBLY FOR MAKING DIFFERENT- COLOUR DOOR AND WINDOW FRAMES BACKGROUND OF THE INVENTION The present invention relates to a metal section member assembly for making different colour door and window frames , for application to inner and outer surfaces of a building, said door and window frames being further adapted to be coated by wood decorating profiles. Aluminium section member systems for changing the colours of the inner and outer surfaces of door and window frames, by applying differently coloured profiles to said inner and outer surfaces, are already known. Further section member assemblies specifically designed for housing therein wood strips, for providing aluminium door and window frames coated by wood materials are also known. However, the above mentioned prior systems do not allow to provide, by using a single section member assembly, door and window frames having inner and outer surfaces of different colours and also coated by wood decorating profiles. SUMMARY OF THE INVENTION Accordingly, the aim of the present invention is to provide an aluminium section member assembly, specifically designed for providing the two above disclosed aesthetic and chromatic effects, while allowing the users to meet their requirements, and this by using a single section member assembly or series . Another object of the present invention is to provide such a section member assembly the section members of which can be applied either with a snap type of operation or a pressing type of operation, by using anchoring elements which can be locked by a turning movement through substantially 90°. Another object of the present invention is to provide a section member assembly the section members of which have either like or different colours, thereby allowing the user to easily provide inner and outer surfaces of door and window frames of like or different colours, and, if desired, coated on their inside or outside surfaces, either partially or fully, by wood profile frames, having a lot of desired colours to be selected by the user depending on the contingent requirements . The above mentioned objects, as well as yet other objects, which will become more apparent hereinafter, are achieved by a section member assembly, having a complex constructional configuration, and provided with " Q " shaped lugs, adapted to snap receive therein section members provided with snap engagement surfaces, mutually converging and provided with a rear abutment portion for locking decorative outer section members to constructional section members adapted to form the uprights and cross-members of door and window frames. According to another aspect of the present invention, the inventive section member assembly further comprises section members provided with " U " shaped fins, and associated rubber gaskets, for engaging with projecting elements, coupled to the constructional or structural section members of the subject aluminium door and window frames. BRIEF DESCRIPTION OF THE DRAWINGS The above mentioned and other constructional features of the section member assembly according to the present invention will become more apparent hereinafter from the following detailed disclosure of some preferred embodiments thereof, with reference to the figures of the accompanying drawings, where: Figure 1 is a cross-sectioned top plan view illustrating a portion of a frame including a plurality of different shape section members which are so coupled as to provide outer section members snap engaged to one another and which can be suitably changed and differently assembled so as to provide profiles of like or different colours on the inner and outer surfaces of said frames; Figure 2 illustrates that same frame portion of Figure 1, provided with section members also adapted to receive wood profiles, to change their aesthetic characteristics, depending on the requirements ; Figure 3 is a cross-sectioned top view illustrating another exemplary embodiment of a composite section member made by using individual section members and covering elements having snap engaging members, which can be associated with further section member portions having a "D" shape, or also provided with projections engageable with restraining profiles made of a rubber material provided for engaging with the end portions, of " U " shape, of suitably contoured section members ; Figure 4 illustrates that same frame portion shown in Figure 3, but including wood profiles applied to aluminium bearing section members by suitable anchoring elements; Figure 5 is a cross-sectioned side view illustrating a section member provided on its outside of a wood coating, applied to said section member by anchoring elements ; Figure 6 illustrates a further section member which can be snap engaged with the structural section members of the frame; Figure 7 illustrates a further pressure- applied section member provided with a pair of " Li " shape lugs provided for engaging, through rubber gaskets, with suitably contoured projecting elements; Figures 8 and 10 illustrate two further exemplary embodiments of snap engaging section members, designed for engaging with " " shape elements ; Figure 9 illustrates a further section member provided with "U" lugs, for application to a main frame section member, likewise to the section member shown in Figure 7 ; Figures 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26 and 27 illustrate further section members constituting respective variations of the section members provided with one or more " j j " lugs , for supporting wood profile frames by suitable anchoring elements having an approximately rectangular configuration and provided with notches formed at a middle portion of their small sides; Figure 29 is a perspective view illustrating a portion of a metal frame to which anchoring elements are applied; Figure 30 is a further perspective view illustrating a wood frame and an aluminium frame provided for association with one another; and Figure 31 is yet another perspective view illustrating a method for coupling the wood frame to the aluminium section member frame: in this connection, it should be pointed out that, as stated, the anchoring elements herein used can be caused to turn about suitable pivot pins for coupling the main section members to the wood decorating elements, which latter are in turn coupled to one another to define wood frames . DESCRIPTION OF THE PREFERRED EMBODIMENTS The above and yet other features of the present invention will become more apparent hereinafter with reference to the number references of the accompanying drawings, where: Figure 1 illustrates a frame 1 , formed by a specifically designed section member 4 which can be coupled to a bearing frame. More specifically, said frame 1 comprises a section member, operating as a fixed upright 2, including an end portion having a " [j " shape contour, with teeth 5 and 6 , therewith are engaged converging teeth 40 and 41 of snap engageable section members 3, including hollows 42 and 43 and detent rear fins 44. The section member 3, applied to the fixed frame, can be suitably replaced by any other section member having either a like or a different colour, with respect to that of the inner section member 2. The exemplary frame shown in Figure 1 comprises moreover a snap engaging element 12, also provided with said converging teeth 40 and 41 to be engaged in a " ( " shape section member 13, having its end portions 5 and 6 snap engaging in suitable hollows 42 and 43 provided with end of stroke fins or detent fins 44. Thus, the section member 12 can be easily anchored to the section member 15 of the movable wing and can be replaced by different colour section members, depending on the aesthetic effect to be achieved. The subject frame is moreover provided with a glass-restraining element 20 and a lug 18, constituting an integrating portion of the section member 15 and supporting a gasket 19. Said section member is moreover provided with a further gasket 20 arranged between the glass pane 28 and section member 15, ending with a lug 14 supporting, in turn, a projecting element 21 which, through a rubber gasket, allows a coupling to the section member 15 of the section member 17, which can be easily replaced by a different colour section member. The composite section member shown in Figure 1 is further illustrated in Figure 3. In this figure, the snap replaceable elements 3 and 12 are applied to the movable wing of the frame and to the fixed wing thereof respectively, by using the above mentioned snap converging teeth 40 and 41 which are engaged with a "[ j " shape section member having projecting teeth 5 and 6 to be locked in the hollows 42 and 43 and against the limit or detent fins 44 formed in said section members 12. The several exposed to the view section members can be accordingly easily applied and replaced by different colour section members, since they are snap and/or pressure engaged to the section members 22 and 26. Figure 3 shows the section member 17 applied by suitable gaskets engaged in "U" shape hollows 50, in turn designed for engaging with projecting elements 21 formed on the body of the supporting section member 22. In particular, said supporting section member 22 is further provided with lugs for supporting a glass-restraining gasket 19 which, together with said gaskets 20, allow to easily affix the glass panes 28. Figure 3 further illustrates other sealing gaskets 10, designed for providing the frame with a perfect air tightness, while assuring a very good thermal insulation. In this connection it should be pointed out that the section members of the inventive section member assembly can be devoid of any thermal-cut properties while allowing, differently from prior like section members, to provide door and window frames having inner and outer surfaces of different colours or coated by a wood material. It should be moreover pointed out that the wood strips 24 are applied to the window frames by using suitable anchoring elements 30, having an approximately rectangular configuration, and being provided with notches or cuts formed at an intermediate portion 31 of their small sides. The mentioned anchoring elements 30, in particular, are engaged, or threaded, in suitable " " shape lungs formed in the section members of the subject section member assembly and being coupled to the mentioned wood strips 24 by a pin 33 having a head of square or hexagonal configuration, said pins allowing a partial turning through 90° of said anchoring elements 30 after having engaged the mentioned profiles and anchoring elements in said " " shape section members. Thus, the wood strips 24 will be locked to provide further frames 35 for said " | " lungs 5 and 6 of the aluminium section members constituting the subject frames 37. The above mentioned 90° rotation is performed by using suitable wrenches 36 for properly turning the above mentioned substantially rectangular anchoring elements having, as shown, greater and smaller sides. While the invention has been disclosed with reference to preferred embodiments thereof, it should be apparent that the disclosed embodiments are susceptible to several modifications and variations all of which will come within the scope of the appended claims .
