Description: The present invention relates to a coordinated section member assembly for making armoured window and door frames. As is known, armoured window and door frames are usually used for banks and the like. Conventional armoured window and door frames, however, have discontinuity lines susceptible to allow for a shell impinging thereon to pass through the window or door frame. Also known is the fact that the mentioned discontinuity lines are conventionally formed at the corners of the window or door frames since, in this zone, the reinforcing foils or blades, cut at 45°, simply abut onto one another. There are also known window and door armoured frames in which the reinforcing blades are coupled without any interruption lines; however, this approach requires that the window and door frames be subjected to complex milling operations, with a consequent increase of the finished product. The DE-U- 8 016 077 document discloses a section member assembly substantially corresponding to the pre-characterizing portion of the main claim, and including an armouring section member provided with a double armouring seat. The GB-A-2 029 480 document discloses a section member assembly in which the armouring protection is obtained by a lot of substantially abutting armouring plate. The DE-A-3 711 936 reference discloses a section member assembly in which the armouring seats are defined by the connection of several section members, in each seat there being engaged a single armouring plate. Accordingly, the task of the present invention is to overcome the above mentioned drawbacks, by providing a coordinated section member assembly, for making armoured window and door frames, which affords the possibility of making armoured window and door frames devoid of any discontinuity lines or zones between the reinforcing foils or blades. Within the scope of the above mentioned task, a main object of the present invention is to provide such a coordinated section member assembly, for making armoured window and door frames, which affords the possibility of easily and quickly making window and door frames with different opening patterns. Another object of the present invention is to provide such a coordinated section member assembly, for making armoured window and door frames, the section members of which are able of housing the reinforcing blades or foils, without the need of subjecting said section members to machining operations. According to one aspect of the present invention, the above mentioned task and objects, as well as yet other objects, which will become more apparent hereinafter, are achieved by a coordinated section member assembly, for making armoured window and door frames, having the features of the characterizing part of the main claim. BRIEF DESCRIPTION OF THE DRAWINGS Further characteristics and advantages of the coordinated section member assembly according to the presents invention will become more apparent hereinafter from the following detailed description of a preferred, though not exclusive, embodiment of said section members and portions of the window and door frames made thereby, which are illustrated, by way of an indicative but not limitative example, in the figures of the accompanying drawings, where: Figure 1 shows a cross-sectional view of the section member used for making fixed frames; Figure 2 shows a further cross-sectional view of the section member used for making the movable frame of inwardly openable windows; Figure 3 shows the section member for making the movable frames of outwardly openable windows or doors; Figure 4 shows a cross-sectional view of a section member for making the movable frame of inwardly openable doors; Figure 5 shows a cross-sectional view of a section member adapted to operate as an abutment for outwardly openable doors and windows; Figure 6 shows a cross-sectional view of a glass plate restraining section member; Figure 7 is a cross-sectional view illustrating the two central uprights of a two-wing inwardly openable door; Figure 8 shows the two adjoining uprights of a two-wing window; Figure 9 schematically illustrates a wing frame with a fixed side frame; Figure 10 is a partial cross-sectional view illustrating an outwardly openable wing window; Figure 11 is a further partial cross-sectional view showing a magnetic closure wing window; Figure 12 is a cross-sectional view illustrating the base portion with a glassed door; and Figures 13 and 14 are respectively a front view and a side view illustrating the procedure for superimposing reinforcing or armouring foils or baldes, at the corner regions of the window and door frames. DESCRIPTION OF THE PREFERRED EMBODIMENTS With reference to the Figures of the accompanying drawings, the coordinated section member assembly for making armoured window and door frames according to the invention, comprises a section member for making fixed frames 1, a section member 2 for making the movable frame of inwardly openable windows; a section member 3 for making the movable frame of outwardly openable windows; a section member 4 for making the movable frame of inwardly openable doors; an auxiliary section member 5 for making two-wing windows; a further auxiliary central section member 6 for making two-wing doors; an abutment section member 7 adapted to provide an abutment for outwardly openable windows and doors; a section member 8 providing a door band and/or base; a glass-plate restraining section member 9; and a section member 10 to be used as a fixed upright or cross member. In this connection it should be pointed out that of the above mentioned section members, tose provided for housing the armouring foils or blades 11 are provided, at corresponding positions, with a respective double seat 12. Thus, owing to this provision, the reinforcing foils will assume, at the corner regions, a superimposed condition, thereby covering any interuptions which, on the other hand, are usually formed in conventional armoured window and door frames. The mentioned foils or blades, in particular, can be provided, at each armouring zone, as a single blade or a double blade depending on the armouring performance to be obtained. The same armouring blades, moreover, can be made either of steel or aluminium, depending on the armouring performance to be obtained. The section member assembly according to the invention provides the possibility of easily and quickly making window and door frames with different opening patterns (such as windows and doors having one or two wings, inwardly or outwardly openable, vasistas frames and so on). Air and water tightness is provided, in the case of the windows, by suitable magnetic gaskets 13 specifically designed for a long duration. For the doors, said tightness is provided by conventional gaskets,preferably made of ethylene-propylene elastomeric materials (such as Dutral) and the like. In this connection it should be pointed out that the spaces provided for receiving the glass plates 15, which will have a great thickness, can be of the order of 63 mm (that is for a glass plate having an overall thickness of 57 mm). Moreover, the mentioned glass plate restraining section member 9 will have a suitably great thickness since it must be able of firmly restraining the glass plate even if the latter is impacted by a shell or projectile. At the reference numbers 16 and 17 there are respectively indicated a hinge assembly and a flush covering section member. In particular, the fixed frame section members will have preferably a depth of 80 mm, whereas the movable frame section members will have a depth from 80 to 88 mm. From the above disclosure it should be apparent that the section member assembly according to the invention fully achieves the intended task and objects. While the invention has been disclosed and illustrated with reference to preferred embodiments thereof, it should be apparent that the dissclosed embodiments are susceptible to several modifications and variations all of which will come within the scope of the appended Claims.
