Description

BACKGROUND OF THE INVENTION

[0001] The present invention relates to a coordi­nated section member assembly for making armoured window and door frames.

[0002] As is known, armoured window and door frames are usually used for banks and the like.

[0003] 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.

[0004] 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.

[0005] 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.

SUMMARY OF THE INVENTION

[0006] 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.

[0007] 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.

[0008] 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.

[0009] 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, characterized in that said section member assembly comprises: a fixed frame section member; a movable frame section member for making inwardly openable window frames;
a movable frame section member for making outwardly openable window frames; a movable frame section member for making inwardly openable doors;
an auxiliary central section member for making two-wing wondow frames; a further central auxiliary section member for making two-wing doors; an abutment section member for providing an abutment for outwardly openable frames; a section member pro­viding a door band and/or base; a glass plate re­straining section member; a section member adapted to be used as a fixed upright or cross member; said fixed and movable frame section members being pro­vided, at the armouring zones thereof with a double seat adapted to house corresponding steel or alumi­nium armouring foils or blades.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] 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 mem­ ber 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.

[0012] 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.

[0013] 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.

[0014] 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.

[0015] The same armouring blades, moreover, can be made either of steel or aluminium, depending on the armouring performance to be obtained.

[0016] 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).

[0017] Air and water tightness is provided, in the case of the windows, by suitable magnetic gaskets 13 specifically designed for a long duration.

[0018] For the doors, said tightness is provided by conventional gaskets,preferably made of ethylene-­propylene elastomeric materials (such as Dutral) and the like.

[0019] 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).

[0020] 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.

[0021] At the reference numbers 16 and 17 there are respectively indicated a hinge assembly and a flush covering section member.

[0022] In particular, the fixed frame section members will have preferably a depth of 80 mm, where­ as the movable frame section members will have a depth from 80 to 88 mm.

[0023] From the above disclosure it should be apparent that the section member assembly according to the invention fully achieves the intended task and objects.

[0024] 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 and spirit of the appended Claims.
