Description

DESCRIPTION

SECURITY OR ARMOURED STRUCTURE FOR CLOSING A CORRESPONDING OPENING IN A WALL OR THE LIKE.

Technical field

This invention relates to a security or armoured structure, in particular a door, for closing a corresponding opening in a wall, or the like, of a respective construction, in particular a building.

Background art

Security or armoured doors are known in the prior art for closing corresponding openings provided in a wall of a building, which, generally, comprise a respective single panel, which acts in conjunction with a corresponding fixed frame, and wherein the panel comprises a respective body of planar extension which extends to close mainly the space which is defined by the opening in the respective wall of the building.

Generally, the internal structure of the known security or armoured doors comprises a body of planar extension which consists of a large flat sheet to which are fixed one or more omega-shaped stiffening profiles, and corresponding reinforcement profiles are fixed on the perimeter which retain the covering panels, for example made of wood, of the door on the structure of the panel.

In the prior art security or armoured doors, the stiffening profiles and frames are made integral with the supporting sheet metal by corresponding welding points. In effect, every plant for producing security or armoured doors comprises a special welding department, where robot welding machines are prominent, working quickly, sometimes 24/7, to provide the parts to be assembled on the subsequent assembly lines.

However, the robot welding machines are not able to do everything, and finishing by hand therefore continues to exist, since some welds require a specific preparation after the processing by the robot and there are therefore, downstream of the robot welding machines, manual welding stations which finish the bodies of the security or armoured doors in production.

In practice, the costs of the plant for making security or armoured doors are excessively high. Such a high cost of the prior art plants for making security or armoured doors is mostly determined by the high cost of the robot welding machines, which, in any case, do not eliminate the need to perform welding directly by the personnel, with consequent harm for the health of these workers.

Moreover, such a security or armoured structure does not allow a homogeneous insulation of the entire surface of the panel, which is achieved using corresponding polystyrene panels, which are positioned alongside the omega-shaped reinforcement profile, or profiles. In short, the prior art security or armoured doors define, at the omega-shaped reinforcement profile, or profiles, a thermal and acoustic bridge which therefore makes them disadvantageous from the point of view of thermal and acoustic insulation.

Moreover, such a structure of the security or armoured door makes it excessively rigid and easily cut by burglars, with consequent ease of breaking in and entering the protected room. In effect, since the structure of the welded panel is excessively rigid, it is sufficient for burglars to hammer with pointed tools along a respective strip of the panel to easily cut the body of the welded panel.

A further problem, which makes the armoured doors currently produced not very efficient from the point of view of security, relates to the closing of the door, which is performed only with the guards which are inserted into corresponding holes of the frame surrounding the panel and which can be easily tampered with, nullifying the closing action applied by the armoured door.

A further problem of the prior art security or armoured doors relates to the excessive weight of these doors when provided in the form of a fire door. In effect, in these cases, plasterboard is used as the internal insulation instead of the normal expanded polystyrene, which, however, makes the armoured panel excessively heavy, and, therefore, difficult to transport and install, and also causes excessive stresses to the hinges of the panel. Moreover, since the prior art welded panels use internal omega-shaped stiffening profiles they are unable to achieve maximum levels of insulation relative to the fires. In effect, the omega-shaped stiffening profiles define corresponding means for rapid transfer to the outside of the temperature inside the room which is subjected to fire.

A further problem with prior art armoured doors relates to fitting of the lock block, which is inserted before closing the structure of the panel and which in the event of a fault requires complete dismantling of the panel for accessing the lock block, all of which is time-consuming for the assembly and dismantling.

Another problem which has an adverse affect on the construction costs of the prior art armoured doors relates to the need to make armoured doors which open to the right and further armoured doors which open to left. In practice, excessive quantities of components which satisfy both the construction requirements must be kept in the store.

A further problem regards the assembly costs of the door at the opening to be closed, as it comprises fixing the counterframe at the surface which defines the opening to be closed in the respective wall of the building and therefore fixing this counterframe to the fixed frame of the door. This results in excessive setup times and costs.

The need is therefore felt in the sector for security or armoured doors which can be made at relatively low cost and which have a high level of quality from the point of view of the solidity, and adaptability to the various technical requirements, for example thermal and acoustic insulation, and which are easy to set up.

The need is also felt in the sector for armoured doors which also have an attractive appearance. Summary of the invention

This invention therefore proposes a new solution as an alternative to the solutions known up to now and, more specifically, proposes to overcome one or more of the above mentioned drawbacks and/or problems and/or to meet one or more of the needs felt in the trade or inferable from the above.

The invention accordingly provides a security or armoured structure, in particular a door, for closing a corresponding opening in a wall or the like of a building, comprising panel means, in particular in the form of a respective single panel, which act in conjunction with corresponding frame means, which are fixed relative to the building; the panel means comprising a respective body of planar extension which extends to close mainly the space formed by the opening; characterised in that the closing body of planar extension is in the form of a corresponding closed, or at least partly closed, box-shaped element.

In this way, it is no longer necessary to use omega-shaped stiffening profiles inside the structure of the panel and a structure is obtained which is sufficiently resistant and at the same time elastic, which has a more effective resistance to attempts at cutting or forced disassembling of the panel.

In effect, since the structure of the main planar body of the panel is elastic and not rigid, as is the case with the prior art welded panels, when the cutting element engages the box-shaped element the latter yields elastically without breaking or cutting, thus nullifying or rendering excessively lengthy the attempted forcing of the armoured door. In practice, more time is required for disassembling this door compared with prior art doors and the break-in attempt is more likely to be prevented. Moreover, the inside of the box-shaped body may be entirely filled with insulation, with greater thermal insulation and acoustic efficiency, as well as insulation against fires.

Detailed description of preferred embodiments of the invention

Figure 1 illustrates a preferred embodiment of the structure, in particular in the form of a security or armoured door 10 for closing a corresponding opening A defined in a wall M or the like of a construction, in particular a building and which is defined by a corresponding surface generally quadrangular which surrounds or delimits the opening.

As illustrated, the structure or door 10 comprises respective panel means, in particular in the form of a respective single panel, 12, which act in conjunction with corresponding frame means 14, in particular supported in a pivoting fashion by these and being designed to engage with these in the closed condition of the door, wherein the space which is defined by opening the corresponding wall or the like of the building is closed.

More specifically, the frame means 14 are fixed relative to the building, in particular being fixed at the surface which surrounds or which defines the opening A to be closed.

More specifically, as may be inferred with reference to Figures 2 and 3, the panel means 12 comprise a respective body 13 of planar extension, which extends to close, at least mainly, the space which is defined by the opening A.

Advantageously, the closing body 13 of planar extension is in the form of a corresponding closed, or at least partly closed, box-shaped element.

More specifically, advantageously according to this preferred embodiment, the box-shaped body 13 is fully closed, as will become clearer as this description continues.

In this way, it is no longer necessary to use omega-shaped stiffening profiles inside the structure of the panel and/or a structure is obtained which is sufficiently resistant and at the same time elastic, which has a more effective resistance to attempts at cutting or forced disassembling of the panel. In effect, since the structure of the closing body is elastic and not rigid, when the cutting element engages the box-shaped element, the latter yields elastically without breaking or cutting. In practice, more time is required for disassembling this door compared with prior art doors and the break-in attempt may also be avoided. Moreover, as will become clearer as this description continues, the inside of the box-shaped body may contain insulating material with a greater thermal and acoustic insulation and fire safety efficiency.

In particular, advantageously, the closing body 13 of planar extension comprises a large panel or planar sheet 131 , in particular which is advantageously designed to be placed, in use, at an inner face or the outer face of the panel means 12 or the structure and which extends transversely to the direction of passing through the opening A closed by this structure.

Further advantageously, the closing body 13 of planar extension comprises a second large panel or plate sheet 132, which extends transversely, longitudinally spaced, and preferably parallel, to the first large panel or planar sheet 131 , and which is advantageously designed to be placed, in use, at the inner or outer face, and in any case opposite to that at which the first large panel or planar sheet 131 is positioned.

Advantageously, the first and/or the second large transversal panels 131 , 132 are made of corresponding metal sheet preferably flat and quadrangular in shape, in particular, rectangular.

More specifically, as may be evinced with reference to the subsequent Figure 4, the closing body 13 of planar extension comprises a respective lateral peripheral panel, in particular a first and a second, transversally opposite, lateral peripheral panel 133, 134, which extend longitudinally, especially extending between the first and second transversal panels 31 , 132 of the closing body 13. Further advantageously, the closing body 13 of planar extension comprises a respective upper peripheral panel 135 and/or a respective lower peripheral panel 136, in particular extending longitudinally between the first and second panel or transversal sheet 131 , 132 of the closing body 13.

Advantageously, as will become clearer as this description continues, there are connecting means between corresponding panels 131 , 132, 133, 134, 135, 136 defining the closing body 13 of planar extension, which are in the form of corresponding mechanical connecting means comprising male means which are inserted and retained in corresponding female means.

This avoids the need to perform welds, with corresponding construction advantages, in particular avoiding the production of doors which have excessive structural fragility.

More specifically, advantageously, the female means and the male means for connecting between the panels constituting the box-shaped body are rendered integral with each other by a corresponding pressing and folding of the female means on the male means.

Advantageously, corresponding punching points distributed along the coupling profile of the female means are defined, the punching points inserting in the corresponding surface of the male means.

There are also, according to a second preferred embodiment of the body 13, which will be illustrated more clearly as this description continues, female means and male means which connect the panels for defining the body 13 defined by corresponding hole means made in the respective panels, in which are inserted corresponding pin means, in particular in the form of corresponding rivet means, as will become clearer as this description continues.

As may be inferred in particular from Figure 4, the respective peripheral panel 133, 134, 135, 136, with longitudinal extension, of the closing body 13 of planar extension is defined by a corresponding shaped profile 15, preferably made of sheet metal.

Advantageously, as illustrated, the profile 15, defining the respective longitudinal panel 133, 134, 135, 136 of the closing body 13 of planar extension, comprises a respective base edge or web 151 , which defines a respective peripheral panel of the closing body 13 of planar extension. Advantageously, the profile 15, defining the respective longitudinal panel 133, 134, 135, 136 of the closing body 3 of planar extension, comprises a respective side edge, or wing, in particular a first and a second opposite side edge or wing, 152, 153 respectively extending, in particular as illustrated perpendicularly, from the base edge, or web, 151 defining the peripheral panel of the closing body 13 of planar extension.

Advantageously, as may be inferred in particular from Figure 4, from the respective lateral edge or wing 152, 153 of the shaped profile of the metal sheet, which defines the respective peripheral wall 133, 34, 135, 136 of the closing body 13, in particular from the free end of it, extends a corresponding appendage 154, 155, which is folded in the opposite direction to the direction of extension of the lateral edge or wing 152, 153, or in a direction of the base edge or web 151, and which defines, with the respective wing 152, 153, a space T50 for introducing a corresponding peripheral edge B of the respective large panel of planar or transversal extension 131 , 132 of the closing body 13 of planar extension.

In this way, pressing and bending the appendage 154, 155 towards the corresponding wing 152, 153, with the interposing of the corresponding peripheral edge B of the respective main planar panel 131 , 132 and defining in the appendage 154, 155 corresponding punches distributed along the extension of the appendage 154, 155, results in a sound and resistant connection between this appendage 154, 155 and the corresponding edge B of the corresponding large transversal panel, 131 , 132, or between the corresponding peripheral panel 133, 134, 135, 136, and the respective large planar panel 131 , 132.

Advantageously, there are means 154, 155, B for connecting the respective peripheral panel 133, 134, 135, 136 to the respective large panel 131 , 132 of planar extension.

In this way, connecting means are also defined between the opposite large transversal panels 131 , 132 of the closing body 13 of planar extension.

Advantageously, there are also means for connecting the respective peripheral panel 133, 134, 135, 136 to the corresponding adjacent peripheral panel 133, 134, 135, 136.

Advantageously, the means for connecting the respective peripheral panel 133, 134, 135, 136 to the corresponding peripheral panel 133, 134, 135, 136 comprise corresponding bracket means 17, which are clearly illustrated in Figure 5.

In this way, a particularly solid and resistant structure is obtained for the main resistant body 13 of the panel means.

More specifically, advantageously, as illustrated in Figure 5, the bracket means 17 comprise a first wing 171 for engaging and fixing to the respective peripheral panel 133, 134, 135, 136 and a second wing 172 for engaging and fixing to the corresponding and adjacent peripheral panel 133, 134, 135, 136.

Means 175 are advantageously provided for fixing the respective bracket means 17, in particular the respective wing 171 , 172 of the bracket means 17 to the respective peripheral panel 133, 134, 135, 136.

The means for fixing the respective bracket means 17 to the respective peripheral panel 133, 134, 135, 36 comprise respective pin means 175, in particular in the form of corresponding rivet means, which are inserted in corresponding holes 176 provided in the bracket means 17, in particular in the respective wing 171 , 172 thereof, and in corresponding holes 157 provided in the respective peripheral panel 133, 134, 135, 136, as may be inferred from Figure 3.

More specifically, as illustrated, each wing 171 , 172, of the bracket 17, has a first and a second hole 176, 176 for inserting corresponding rivets 175 and corresponding first and second holes 157, 157 are provided in the corresponding peripheral panel 133, 134, 135, 136 close to the respective end for mutually coupling of these.

Advantageously, as may be inferred from the drawings, the respective wing 171 , 172 of the bracket means 17 comprises a respective flat portion 173, 173 for engaging an opposite outer face of the respective peripheral panel 133, 134, 135, 136.

Advantageously, the bracket means 17 define means for engaging and resting on the corresponding large panel 131 , 32 of planar extension, in particular on both the opposite large panels 131 , 132 of planar extension. The means for engaging and resting on the corresponding large panel 131 , 132 of planar extension, in particular for engaging and resting on both the opposite large panels 131 , 132 of planar extension, comprise a corresponding appendage 174, which extends in the plane of the corresponding panel 131 , 132 of planar extension, perpendicularly to the respective flat portion 173, 173 of the respective wing 171 , 172 for engaging the respective peripheral panel of the bracket means 17.

This makes a body 3 of planar extension having considerable resistance and which at the same time remains advantageously flexible.

Advantageously, the body 13 of planar extension, which extends to close mainly the space formed by the opening, forms a respective large inner chamber 130, as clearly illustrated in Figure 2.

Further advantageously, the body 13 of planar extension, which extends to close mainly the space formed by the opening A comprises respective insulating means 18, which are preferably housed in the inner chamber 130 of the body 13, in particular extending for the entire width, or substantially for the entire width, of the inner chamber 130.

More specifically, the insulating means 18 extending for the entire width of the inner chamber 30 in particular make contact with or are in the vicinity of the inner faces of the respective panels, 131 , 132, 133, 134, 135, 136, which define the body 13 of planar extension. Preferably, the insulating means comprise expanded polystyrene, in particular are completely made of expanded polystyrene, preferably made in a single panel, and are housed in the chamber 130, in particular before closing the body 13 of planar extension.

Further advantageously, it is possible to use insulating means which have a high fire resistance.

In this case, advantageously, the insulating means 18 which may be used are autoclaved aerated concrete or gas concrete, which is advantageously light in weight and allows a good movement of the structure during installation and setting up.

More specifically, corresponding blocks of autoclaved aerated concrete or gas concrete are used, which are located side by side inside the chamber 130, before closing the box-shaped body 13.

As may be inferred from Figure 1 , the panel means 12 comprise covering means 30 which are provided at the inner and/or outer face of the panel means 12.

More specifically, the covering means 30 are in the form of a corresponding planar panel, in particular a first and a second planar panel, respectively located at a respective inner or outer face of the panel means 30, more specifically in contact with the corresponding face of the body 13 of planar extension.

More specifically, the planar covering panel 30 may be made of any desired material, for example wood or plastic or another material.

Advantageously, as may be inferred with reference to Figure 6, the panel means 12 comprise means 32 for supporting corresponding covering means 30 on the body 3 of planar extension of the panel means 12.

More specifically, the supporting means of the covering means comprise profile means 32, in particular illustrated in Figures 3 and 7, which are fixed peripherally to the body 13 of planar extension of the panel means 12.

More specifically, advantageously, the profile or bottom 32 for supporting the covering means comprise a respective lateral profile, in particular a first and a second lateral profile 32a and 32b.

Further, as illustrated, the profile or bottom 32 for supporting the covering means 30 comprises a respective upper profile 32c and/or a respective lower profile 32d.

In particular, as illustrated, the respective profile 32 supporting the covering means 30 comprises a respective base edge or web 321 for engaging the lateral face of the body 13 of planar extension of the wing means 12, in particular of the corresponding longitudinal peripheral panel of this.

In particular, as illustrated, the respective profile or bottom 32 comprises a respective wing, in particular a first and a second wing 322, 323, which respectively extend from the respective lateral end of the base edge or web 321 , the respective wing 322, 323 inserting inside and in contact with the respective wing 152, 153 of the shaped profile defining the longitudinal peripheral panel of the body 13 of planar extension of the panel means 12. More specifically, the fixing of the respective profile or bottom 32 supporting the covering means 30 is actuated using corresponding pin elements, preferably rivets, which are inserted into corresponding holes 320 provided in the respective profile 32, in particular in the web 321 of this, and in holes 1332 provided in the corresponding longitudinal panel 33, 134, 135, 136 of the body 13 of planar extension.

More specifically, the shaped profile 15 defining the respective longitudinal peripheral panel of the body 13 of planar extension defines a respective groove 1532 for receiving or inserting the profile 32 for supporting the covering means 30.

This defines means which define the corresponding groove means 1532 for receiving or inserting the profile 32 for supporting the covering means 30.

More specifically, as illustrated, the wing 322, which is provided on the inner side of the door, is longer than the wing 321 , which is provided on the outer side of the door.

In particular, as illustrated, the wings 322, 323, like the corresponding wings 152, 153 of the shaped profile defining the lateral panels of the body 13 of planar extension are parallel or substantially parallel to each other. Advantageously, the respective profile 32 for supporting the covering means comprises respective means 324, 325 for retaining the respective peripheral edge of the covering means or panel 30.

More specifically, as illustrated, the means 324, 325 for retaining the respective peripheral edge of the covering means or panel 30 comprise a respective longitudinal appendage 324a, 325a, which extends, in particular parallel to the web 321 , starting from the free end of the corresponding protruding wing 322, 323 and from which respective end of the appendage 324a, 325a extends, in a direction opposite to that of extension of the protruding wing 322, 323, a second appendage 324b, 325b for hooking the corresponding peripheral edge of the covering means or panel 30.

More specifically, advantageously, as illustrated, the free end of the appendage 324b, 325b for hooking the peripheral edge of the covering means or panel 30 has a corresponding end portion 324c, 325c facing backwards.

Advantageously, the respective lateral profile for supporting the covering means, in particular both the lateral profiles 32a, 32b for supporting the covering means 30, has a corresponding opening 150" having dimensions such as to allow the transit inside the locking means 20 and in particular positioned at the opening 150' provided in the corresponding lateral panel of the body 13 of planar extension.

More specifically, the respective profile 32 for supporting the covering means 30 is made of corresponding shaped metal sheet.

Advantageously, as may be inferred also with reference to Figure 7 and 8, there are locking means 20 in this door, which can be respectively closed and opened, for closing and opening the door, in conjunction with the corresponding fixed frame means 14.

More specifically, the locking means 20 comprise a respective lock block 21 , from which extends pin means 22 which are suitably movable between at least a closed position and an open position of the lock.

Advantageously, the locking means 20 are housed inside the body 13 of planar extension, in particular inside the inner chamber 130 of this.

Advantageously, as mentioned, the respective lateral panel 133, 134 of the body 134 of planar extension comprises a corresponding elongated opening 150' for inserting the block 21 of the locking means 20 inside the body 13 of planar extension.

Advantageously, a first opening 150' is provided in the lateral peripheral panel 133 of the body 13 of planar extension and a second opening is also provided in the opposite lateral peripheral panel 134 of the body 13 of planar extension.

In this way, a door can be made which may operate both as a door with opening to the right and as a door with opening to the left, without requiring the provision of suitable and separate components for making the openings to the right and to the left of the corresponding door.

Advantageously, as may be inferred from Figure 1 , the insulating means 18 have, laterally, a corresponding compartment 181 , and preferably have a first and a second compartment 181 , 181 provided at lateral opposite edges of the insulating means 18, the respective compartment 181 defining means for housing the locking means 20, and in particular the lock block 21.

More specifically, as may be inferred, the respective compartment 181 opens at the opening 150' which is provided in the respective peripheral lateral panel 133, 134 of the body 13 of planar extension, and/or at the opening 150" which is provided in the bottom profile 32.

As may be inferred, the pin means 22 of the locking means 20 protrude outside the body 13 of planar extension through the opening 50', which is provided in the respective lateral peripheral panel 133, 134 of the body 13 of planar extension, and passes through the opening 150", which is provided in the bottom profile 32.

In particular, the insertion and removal of the lock in the panel of planar extension or panel of the door is particularly easy.

It is sufficient in effect to lock or release using corresponding screws which are inserted in corresponding holes of the front plate 205 of locking means for fixing to the corresponding bottom profile 32 and extract the lock block 21 through the opening 150', 150", which can all be done in an extremely easy manner without the need, in the case for subsequent removal, of having to removing the entire door, as was necessary in the prior art.

As illustrated in Figures 1 and 6, advantageously, the panel means 12 comprise bar means 24 which engage a corresponding elongate seat 25 provided in the fixed frame means 14 for clamping the panel means 12 to the fixed frame means 14.

The bar means 24 extend from the respective peripheral edge of the panel means 2 for part of the length of the corresponding edge, in particular for a length greater than half the extension of the corresponding peripheral edge of the panel means 12, and preferably substantially for the entire length of the lateral edge of the panel means 12.

More specifically, as illustrated, the bar means 24 extend vertically.

Advantageously, there are first 24 and second, not illustrated in detail in the accompanying drawings, bar means, in particular which extend from opposite edges of the panel means 12, in particular from opposite lateral edges of the panel means 12.

Advantageously, the bar means 24 are supported by the pin means 22 for the locking means 20.

Advantageously, the bar 24 is removably fixed to the end of the pin means 22, which, in particular, comprises a plurality of parallel pins, of the locking means 20, preferably using corresponding screw means, not particularly illustrated in the accompanying drawings, and which are inserted into corresponding threaded holes opening at the end transversal face of the pin means 22.

Advantageously, the bar means 24 have a corresponding through hole 240 for the free transit of the latch pin 201.

In practice, when the structure, or armoured door, is closed in a stationary fashion, by using the key, or similar means, to operate the lock 20, the bar 24 is moved from a retracted position, which is close to the corresponding lateral edge of the sash, towards an extended position, away from the corresponding lateral edge of the sash, inserting in a corresponding advantageous seat S of the fixed frame 14, which is described in more detail below.

The clamping action is further reinforced, if, on the side opposite the sash, there is the presence of a corresponding clamping bar, even if fixed to the corresponding lateral edge of the sash, in particular where there are the hinges for rotation of the sash 12 relative to the fixed frame 14.
