Firstly with reference to FIG. 1, a metal door armored with a leaf comprises two parallel vertical panels 1, 2 separated by a predetermined distance, as will be seen below. The panels 1 and 2 are the present embodiment made of a steel sheet of suitable thickness.

At the upper and adjacent periphery of the frame, on the right in FIG. 1, are provided in the panel 1, at the bottom of cavities 6 (see FIG. 6) formed for example by stamping, a plurality of holes 4. In the same way , holes 7 (see FIG. 6) are provided in the panel 2 at the bottom of similar cavities 8, each hole 4 being aligned with a hole 7.

In addition, holes 3 are made in the sheet 1 while being regularly spaced along a network of horizontal and vertical lines, as shown in FIG. 1.

The holes 3 are also formed in associated cavities 5. Likewise, holes 9 formed in the bottom of cavities 10 are formed in the panel 2 in locations corresponding to those of the holes 7 (see FIG. 11).

With reference to FIGS. 3 and 11, the or each leaf of the armored door according to the present embodiment comprises, between the panels 1 and 2, a frame made up of a plurality of irons 11 of U-shaped section. The two parallel members of each shoe 11 respectively have a plurality of holes 12, 13 respectively aligned with the holes 3, 9 of the panels 1 and 2. The panel 2 is fixed to the reinforcing bars 11 by means of non-removable bolts 14 with head smooth and comprising between the head and the rod an eccentric flange associated with nuts 15 and washers called "star" 16. The panel 1 is fixed to the irons 11 by means of self-tapping screws 17 and star washers 18, the two panels 1 and 2 thus being made integral, and in a non-removable manner from the side of the panel 2, located outside.

As shown in FIG. 3, panels such as rock wool 19 of suitable thickness, having well known thermal and acoustic insulation qualities, are inserted between the panels 1 and 2 at the places left free by the irons of frame 11.

The armored door according to the invention further comprises, taking the place of the lateral envelope of the or each leaf in its region adjacent to the frame, a profile 20 for adjusting the width (see FIGS. 4 to 8), the section of which presents overall the shape of a U, and including two unit adjustment plates 21, defining extensions of the branches of the U extend slightly recessed with respect to said branches.

In each adjustment plate 21 is provided a plurality of adjustment slots 22 extending perpendicular to the longitudinal axis of the profile 20, three in number in each plate, in the present embodiment. As shown in particular in FIGS. 6 and 7, each slot 22 is respectively aligned with another slot 22 of the adjustment plate 21 as well as with respective holes 4, 7 of the panels 1 and 2. The assembly is held rigidly fixed, with an appropriate overflow of the profile 20 from the edges of the panels 1 and 2 depending on the width of the associated frame - by means of bolts 23 comprising a smooth head, an eccentric flange and a hollow tapped rod internal associated with screws 24 and star washers 25.

The smooth head of each bolt 23 is on the side of the panel 2, thereby making the assembly non-removable from the outside.

On the profile 20 are fixed, for example by electric welding, three female hinge elements 26, with rolling ball, regularly spaced.

As shown in FIG. 8, stiffeners or reinforcing partitions 55 are fixed, for example by sampling, between the two adjustment plates 21 of each profile 20, in order to avoid their crushing when tightening the screws 24 in the bolts 23 .

On the frame angle 27 associated with the edge of the leaf comprising the section 20, the male hinge elements 29 respectively associated with the female elements 26 are fixed, for example.

With reference to FIGS. 4 and 6, on the part of the profile 20 defining the edge of the leaf are appropriately fixed a series of protrusions or safety studs 64 arranged, when the leaves are closed, to engage in holes (not visible) provided in the angle iron and thus reinforce the hinges 26, 29 in particular in the event of an attempted break-in.

With reference to FIGS. 1, 2 and 4, the or each leaf of the armored door further comprises a second height adjustment profile 30, which includes, in a similar manner, two extension adjustment plates 31 arranged to be inserted between the panels 1, 2, and which makes it possible to easily adapt the height of the door to that of the frame.

As shown in FIG. 1, cutouts 33 are provided in the adjustment plates 21 and 31 of the sections 20, 30 to avoid their mutual interference in the angle of the leaf where they meet.

With particular reference to FIG. 4, a nozzle 32 of suitable shape and size is provided at the end of the profile 30 opposite the profile 20, in order to close the lateral vacuum left by said end of the profile 30.

Of course, the adjustment profiles 20 and 30 will be cut, for example with a hacksaw, to adapt to the height and width dimensions of the door.

The fixing of the panels 1 and 2 and of the profiles 20 and 30 is reinforced by first providing in the adjustment plates 21, 31, holes aligned with the holes 4 (Figures 4 and 6) of the panel 1, said holes 4 acting as guides, for example a drill bit. Fastening means with bolts with flat head and hollow rod 23, screws 24 and washers 25 passing through these holes complete the fixing.

With reference to FIGS. 1, 2, 9 and 10, a conventional lock comprising a central lock 34 and two latches 35 and 36 is fixed to the panel 1 of the leaf at suitable locations using smooth head bolts 37, d cap nuts 38 and star washers 39. The barrel 40 of each central lock or lock passes through the panel 2 on the other side of the door and is protected by a so-called barrel guard element 41.

As shown in particular in FIGS. 1 and 2, the conventional lock or lock strikes are replaced by a flat iron 42 fixed, as the case may be, either on the frame or on the edge of the dormant leaf in the case of a leaf door. The position of the strikes 44, 45, 46 of the iron 42 will of course be adapted to the locations of the various locks and locks of the door.

According to an alternative embodiment shown in Figures 12 to 15, the flat iron 47 has a longitudinal slot extending substantially over its entire length.

An appropriate number of strikes 48 with cylinder 49 can be mounted on the irons 47. The position and the adaptation of each striker 48 to its bolt bolt or associated lock can be adjusted using adjustment slots 51, 52 respectively provided in the iron 47 and the keeper 48. The fixing of the keepers on the iron is carried out using screws 53 associated with nuts 54. Such a variant makes it easy to adapt to any type of lock or bolt, in any number, which one wishes to mount on the door .

Referring again to Figure 2, the door with two leaves shown has the following modifications with respect to a door with one leaf. First of all, on the dormant leaf, on the left in the figure, are fixed two bolts 56, 57 taking the place of high and low locking points respectively. Each targette 56,57 can be locked in the locking position by an associated locking screw 58, 59. A first strike 60 of adjustable position is fixed in the upper part of the frame to receive the bolt of targette 56, while a second strike 61, also of adjustable position, will be screwed into the ground to receive the bolt of the bolt 57. A flat iron 42, with adjustable strikes 44, 45, 46 is fixed on the edge of the leaf forming, said strikes being arranged to receive the bolts of the locksmith 34, 35, 36 mounted on the opening leaf, on the right in FIG. 2.

In addition, two profiled angles 62, 63, called "anti-clamp" are respectively mounted on the two leaves with smooth head bolts, so that it is impossible to dismantle them from the outside. These two angles 62, 63 fit together when the leaves are closed, thus making it impossible to introduce a tool during an attempted break-in.

Of course, any type of decorative covering may be provided on the leaf or leaves. In particular, a rigid covering glued or fixed by clips on the surface of the panels 1 and 2 will advantageously make it possible to mask the various cavities and changes in surface level.

A variant embodiment is described below with reference to FIGS. 16 and 17, this variant allowing the thickness of the door to be adjusted to adapt it to the existing frame, in addition to the height and width adjustments to the using the profiles 20.30 mentioned above.

With reference to FIGS. 16 and 17, and in particular to FIG. 16, the or each metallic adjustment section 20 as envisaged above consists here of two sliding parts 67 and 68 of substantially L-shaped section, which define together, once juxtaposed as illustrated, an overall adjustable section of U-shaped section. The thickness adjustment means comprise, on the transverse member of the part 67, a slot 69 perpendicular to the edge of said room. A bolt 70 passes through the slot 69 and a hole of suitable diameter made in the other part 68, and engages in a nut 71, with a so-called "fan" washer 72 interposed, to ensure the fixing of the parts 67, 68 in any relative position giving the assembly of the two parts the shape of a U-shaped profile of appropriate thickness and adapted to the desired thickness of the leaf. This fixing is comp, létée by a plurality of self-tapping screws 74 arranged to be guided by holes 73 formed along the transverse member of the part 67 and to appropriately pierce the adjacent wall of the part 68.

As shown in FIG. 16, the female parts 26 ′ of the hinges are welded to the edge of the part 67 of the sliding profile. Hinge reinforcements 102 are further provided, as above, on the outer face of the transverse member of the part 67, and are arranged to penetrate when the leaf is closed in associated holes formed in the door angle 88 fixed on the door frame.

Figures 16 and 17 illustrate the improvement in adjustment section 20 of each leaf described above. Of course, a structure similar to two L-shaped section pieces will be used for the adjustment section or sections 30 of the door.

As mentioned above, the adjustment of the fixing of the vertical and horizontal sliding parts 21 and 31 of the vertical and horizontal sliding profiles consisting of the parts 67 and 68 is ensured by oblong slots 22, and female screws 75 having on their body two flats receiving the associated threaded parts of male screw 76 with hexagon socket head, the flats being intended to prevent rotation of the screw 75 when the screw 76 is screwed into it.

According to another embodiment, also illustrated in FIG. 16, the means for blocking the rotation may comprise, on a female screw 78, a lug 78a arranged to "bite" into the associated chamfer 77 when the male screw is tightened correspondent 79.

When fixing the sliding parts 21 and 31 to the panels 1 and 2, adjustable bracing or spacing means are provided in the form of two rings 80 and 81 arranged to be screwed one inside the other so as to ensure the appropriate height as a function of the thickness chosen for the leaf, a lock nut 82 being provided so as to avoid accidental unlocking of the two rings. It is clear that the assembly constituted by the elements 80, 81 and 82 replaces the fixed height stiffeners 55, in order to ensure the adaptation to the thickness of the leaf as determined by the profiles. As shown in particular in FIG. 17, all of the convicts 80, 81 are crossed centrally by the male-female screws 76.75 and / or 79.78.

In addition, in order to complete the fixing described above, self-tapping screws 83 ensure the fixing of each sliding part 21 to its associated panel 1 or 2.

In addition, so-called "anti-clamp" angles 84 can be provided on the periphery of the leaf and of the frame. The bolts 87 will be locked using nuts 85 and "fan" washers 86. Note in this regard that a suitable opening 90 is made in the wing of the profile 67 to allow the introduction and the establishment of the various bolts and / or nuts and mounting washers, as well as the introduction of a key. suitable for mounting and tightening. Because of its location, this opening 90 allows the passage of the appropriate key for mounting and tightening the bolts 70, nuts 71 and "fan" washers 72.

As previously indicated, an angle iron 88 is fixed to the angle of the door frame (not referenced) by means of wood screws 89, and has, welded in suitable locations, the male parts 29 ′ of the hinges .

In the foregoing description, the presence of irons 11 of the inner frame of the leaf is also envisaged / Of course, the thickness of these irons must also be adjustable and, to this end, they will also be made in a similar manner to the sliding profiles , of two L-shaped section pieces whose relative positions are adjustable by a slot, bolt, nut and washer assembly, and whose rigid fixing or mutual locking is supplemented by self-tapping screws, the adjustable fixings and the fastenings by self-tapping screws which can for example be alternated.

One of the two parts constituting the framework iron adjacent to the panel 2, can be fixed to the latter by bolting, welding, etc. (100), the other part being fixed to the panel 1, as above. , for example by self-tapping screws.

Finally, note that the frame iron adjacent to the locksmith side of the leaf may have appropriate openings, analog Gues to the above-mentioned openings 90, in order to allow the insertion and tightening of the various nuts and washers intended for the fixing of other "anti-clamp" angles.

Of course the present invention is not limited to the embodiment described above, and includes any variant or modification that may be made by those skilled in the art.

Finally, the invention finds an advantageous application in the rapid and efficient production of armored or burglar-resistant landing doors, this application being cited by way of nonlimiting example.
