Definitions

  • the present invention relates to a bullet-proof door element, the door leaf of which is partly made of multi-ply wood, which is formed from numerous thin hardwood veneers connected by cross-directional fiber directions by particularly resistant adhesive.
  • Such a door element with e.g. 45 mm thick multilayer wood shell is bullet-proof according to class M3, i.e. when fired with a 9 mm Magnum pistol, and splinter-free.
  • the invention consists in that the door leaf has a middle shell made of this multi-layer wood, which is connected on both sides to side shells made from thicker, cross-glued veneers than the multi-layer wood, and that the side shells each have at least one third the thickness of the middle shell.
  • Such a door has the same bullet resistance as the door mentioned at the beginning and is about 40% lighter. It is obvious that this is a decisive advantage, especially when the doors are opened and closed frequently. A lower price can also be achieved due to the smaller amount of multilayer wood.
  • the veneers of the side shells are at least twice as thick as that of the middle shell.
  • edge areas of the door leaf which run vertically when the door element is installed, each consist of a banding which has the same structure as the multilayer wood of the middle shell, in each of which the fold of the door is incorporated and its layers transversely to the plane of the Door leaf run.
  • Such a door is not only bulletproof and burglar-proof, but also fire-retardant, since it resists the attack of flames for a long time (more than 30 minutes).
  • the door leaf 1 of the door element has a middle shell 2, which takes up about half the thickness of the door leaf.
  • This shell is made of multi-ply wood, that is, of numerous hardwood veneers, only about 1 mm thick, which are glued with cross-grain fibers using a particularly resistant adhesive. It is about 30 mm thick.
  • the flanks of the middle shell are each connected to a side shell 3, 4, which also consists of cross-glued veneers.
  • these veneers are much thicker than the veneers of the middle shell, about 2 mm, and have a lower adhesive content, so that they are much lighter than the multi-layer wood (multiplex panels). They each take up about a quarter of the thickness of the door leaf, i.e. they are about half as thick as the middle shell.
  • the door leaf is a total of about 60 mm thick.
  • borders 5, 6 which consist entirely of multilayer wood, which has the same structure as the multilayer wood of the middle shell 2, and whose layers run transversely to the plane of the door leaf.
  • the double-angled door rebate 7,8 is incorporated into each of these bands 5,6. The banding increases the stability of the door leaf against climatic and mechanical attacks.
  • the frame 9, like the clothing 10 and the decorative clothing 11, is made of the same multilayer wood as the middle shell 2.
  • the end faces of the frame 9 and clothing 10 have a shape corresponding to the fold 7.
  • a rod lock 13 On the closing side of the door leaf 1, a rod lock 13 is inserted in a recess 12. It interacts with a rod 14, which actuates a plurality of locking bolts 15, which are distributed over the height of the door leaf, via locking mechanisms accommodated in small cutouts in the door leaf 1.
  • the clothing 10 contains recesses 16 reinforced with striking plates, into which the striking pins engage when the door is closed.
  • the connection between the frame 9 and the clothing 10 is by a seal 18 is on the edge 5 of the door leaf 2 when the door is closed.
  • the rebate is covered by a step in the threshold and a base behind the door.
  • the described door cannot be penetrated by projectiles of the class M3 mentioned, and there are no splinters when firing, whether the door leaf is shot perpendicularly or obliquely at this or its edges or the edges of the frame and clothing.
  • the door leaf is relatively light, so that the attachment does not have to be excessively strong; it also offers little resistance to opening and closing. Thanks to the banding 5.6, it does not warp, so it is also resistant to temperature differences and weather influences.
  • the thickness of the veneers used in the multilayer wood of the middle shell and in the side shells as well as the thickness of the middle shell and the side shells can vary within the scope of the invention from the specified size ranges and thickness ratios; it is essential that the side shells are significantly lighter than the middle shell and each take at least a third of the thickness of the door leaf, preferably about half, but the type and Have firmness.
  • the veneer of the side shells should be at least twice as thick as that of the middle shell, which means that the proportion of glue in the side shells is less than that of wood.
  • the veneers of the multilayered wood are preferably impregnated with the adhesive consisting of plastic, while the adhesive in the side shells only connects the surfaces of the veneers.
  • the frames, cladding and decorative cladding can also consist partly of layers corresponding to the side shells 3, 4. Your multi-ply wood can also differ slightly from that of the middle shell, provided that the strength and resistance remain essentially the same.
