Abstract

The invention relates to a break-in protection wall, that is to say capable of resisting fraudulent attempts at passing through (cutting, breaking down, sawing, forcing in and piercing). It is characterised in that, from the outside E to the inside I, it comprises: - an outer facing 11 reinforced by a metal sheet 12; - a first plate 20 made from an extremely hard material which is resistant to sawing actions; - a second plate 30, forming the framework of the wall, made from an extremely rigid material which is resistant to forcing-in actions; and - at least one fibrous lining 40 arranged between at least two of the above three elements. Application to the doors of dwellings. <IMAGE>

Description

 The present invention relates to burglar-resistant walls, that is to say capable of withstanding fraudulent crossing attempts.

 The invention relates in particular, but not exclusively, to the openings of residential doors.

To facilitate understanding, a description will be given in the following description of residential doors, since these apply more particularly to the invention.

 Residential doors have, since their existence, been the object of very special attention on the part of criminals. The means used by the latter to commit their misdeeds have constantly followed the evolution of the technique. Nowadays, criminals use, in addition to their traditional equipment (crowbar, pliers-monseigneur), portable electric tools (drill, jigsaw, ...); these various tools allow them to tackle the most diverse materials.

 The construction of residential doors unfortunately did not follow this development and, if certain doors resist attacks of the "traditional" type (pushing in using a lever), few doors resist more than a few minutes to attacks more elaborate (drilling, sawing, cutting, ... using hand tools). To obtain this resistance, because of the variety of possible attacks, the so-called armored doors are made of metal sheets of great thickness and great hardness. The disadvantage of these sheets is that they lead to heavy, expensive elements which are difficult to produce using standard tools.

 The present invention overcomes these drawbacks and proposes a new wall for residential doors for this purpose. The invention therefore aims to provide a wall using simple materials which, even if it does not fully resist attack by very powerful means, however, makes it possible to mitigate the risks of such attacks rendering them both long and painful, so that the duration of a break-in attempt as well as the difficulties to overcome have a deterrent effect on a burglar.

 According to the invention, a wall is obtained which is resistant to cutting, cutting, sawing, driving and drilling actions by combining different layers of elements having complementary characteristics in terms of material resistance. The combination of assembly of the elements makes it possible to retain only the qualities of the latter, the interactions between the various elements eliminating the defects.

 According to the invention, the composite wall forming the opening of a door comprises from the outside towards the inside an external facing reinforced by a metal sheet, a first plate made of a material of high hardness resistant to sawing actions. , a second plate forming the framework of the wall, made of a material of great rigidity resistant to the sinking actions, and at least one fibrous lining arranged between at least two of the three elements rci above.

 Other characteristics and advantages of the invention will appear during the description which follows and in the attached drawing to which it refers.

 The single figure is a schematic sectional view of the wall according to the invention.

 The first element 10 consists of a wooden facing 11 (solid, plywood, agglomerated, ...) 4 cm thick on which is screwed on its internal face a metal sheet 12 1.5 mm thick . This element 10 resists cutting and cutting-off (butchering) actions.

 The second element 20 consists of a glass plate 4 mm thick which, because of its high hardness, resists sawing actions.

 - A fibrous lining 40 2 mm thick is placed on either side of the second element 20. It is intended, because of its elasticity, to absorb any shock liable to damage the glass plate, and, in due to its fibrous nature, to hinder piercing actions.

 The third element 30 consists of a sheet metal sheet that can be shaped 2 mm thick, which, because of its high rigidity, resists penetration and puncturing actions. This element also constitutes the framework of the wall.

 The wall thus formed according to the combination described above, makes it possible to resist various attacks which may be suffered during an attempted break-in.

 If an attempt is made to cut up the wall, the metal sheet 12 of the first element 10 will prohibit this action by protecting the facing 11 that is too easily vulnerable.

 If an attempt is made to pierce the wall, the progression of the wick after an easy crossing of the first element will be slowed down by the first fibrous lining 40, winding around the wick, then by the glass plate 20, followed by a second fibrous lining 40 and the third element 30 of great rigidity.

 If an attempt is made to saw the wall, either using a jigsaw after successful drilling of the wall, or using a circular saw, the glass plate 20 will stop this action despite the little resistance offered by the first element.

 And finally, if we try to push in the wall, the third element, forming the framework of the wall, will resist this action, prohibiting it despite the little resistance to this type of attack by the other elements.

 The wall formed of these elements therefore resists cutting, cutting, sawing, driving and drilling.

 Of course, the invention is not limited to the embodiment described, but extends to any variant in accordance with its spirit.

 In particular, the choice of the material making up the second element 20 is not limiting: the glass plate can be replaced by a sheet of high hardness whether or not covering the entire surface of the wall.
