    Burglary resistant grill
    The invention relates to a burglary-resistant grid, comprising a frame as well as mutually parallel slats included in the frame, which frame comprises profiles which are located on opposite ends of the slats.
    Such a grid is known from EP-A-1,617,155. With this known grid, profiles are provided on both the top side, the bottom side and on the upright sides, which together form the frame. Upright support profiles are attached to this frame, from which the slats are suspended. The profiles that form the frame are L-shaped. The disadvantage of this known construction is that it is not well protected against burglary. The support profiles and the profiles of the frame can be bent in a relatively simple manner because they are only single-walled and therefore have a relatively low bending and torsional rigidity. As soon as one succeeds in bending or otherwise forcing the profiles, the slats can be removed. The underlying space is therefore not well protected against unauthorized access.
    In another known grid, steel inserts are included in the slats themselves. Although this measure increases the burglary-resistant capacity of the grille, it has the disadvantage that this approach is relatively expensive.
    The object of the invention is to provide a grid that offers better protection against forcing and burglary attempts. This is achieved in that the profiles have a cavity closed in the circumferential direction, that a reinforcement is accommodated in each cavity and that each cavity and reinforcement extend over the slats viewed in the direction from the end edges.
    The grid according to the invention has profiles which have a cavity closed in the circumferential direction, whereby the bending stiffness and the torsional stiffness of these profiles are relatively high. Such a greater rigidity and strength offers a first protection against forcing, because it becomes more difficult to deform the relevant profiles. This has also made it more difficult to remove the slats.
    A further protection against forcing is obtained by the fact that there is a reinforcement in those closed cavities. Such a reinforcement can consist of a material that offers high strength and high rigidity, such as for example steel. As a result, the deformation of the relevant profiles becomes even more difficult, even if they consist of a relatively flexible material such as aluminum or plastic. Forcing it through sawing and the like is also made more difficult.
    Finally, greater protection is obtained in that both the profiles and the reinforcement in the cavity of the profiles extend over the slats. In particular, they extend over the ends of the slats, such that they can be properly captured behind the profiles of the grid.
    In particular, this protection of the slats can be effected by means of profiles comprising an essentially L-shaped cavity such that one leg of the L-shaped cavity extends from one end face each and the other leg of the L-shaped cavity extends over that end. Fastening means can be provided on the part of the profiles extending over the end face of the slats, by means of which the profiles are fixed to the structure which delimits the opening over which slats extend.
    The reinforcement is also preferably L-shaped, such that one leg of the L-shape of the reinforcement extends into one leg of the L-shaped cavity of the profile and the other leg of the L-shape of the reinforcement extends into the other leg of the L-shaped cavity of the profile.
    According to another possibility, the profiles comprise a substantially U-shaped cavity, such that in each case two parts of the U-shaped cavity extend from each end face and these parts are mutually connected by a hollow intermediate part (27) extending over said cavity. front side. In that case, the reinforcement can also be U-shaped, such that two legs of the U-shape of the reinforcement extend into the two parts of the U-shaped cavity that extend from each end face, which two legs are mutually connected by an intermediate piece located in the portion of the U-shaped cavity that extends over that end face.
    If the leg of the reinforcement extending over the end face of the slats is secured to the relevant structure around the opening, it is ensured that the leg of the reinforcement extending over the slats cannot or hardly be lifted or can hardly be lifted. are pushed away from the slats.
    In particular, this can be achieved if mounting anchors are provided on the end faces for fixing the grating to the boundary of an opening, said mounting anchors being attached by means of rivets and the like to the leg of the reinforcement extending over an end face.
    For further protection of the grid against burglary, the profiles can each comprise a flange-shaped cover piece, which cover pieces are remote from each other. In a further embodiment, the profiles can each extend over the slats from the end sides on either side. The slats are then received in the cavity of the essentially U-shaped cross-section of the profiles thus formed.
    . To further reinforce the construction, each slat can be attached to one of the legs of each profile. In that connection, the profiles extending along the end edges can be mutually connected at their ends by transverse profiles.
    The invention furthermore relates to a façade construction or a panel construction, comprising a façade or a panel in which there is an opening and a burglary-resistant grid as described above covering the opening and which is attached to the edge parts of the façade or the panel surrounding the opening respectively . The corresponding mounting anchors are attached to those edge parts.
    The invention further relates to a profile for the above-described grid, provided with a U-shaped cross-section defined by a double-walled hollow leg, a single-walled leg as well as a double-walled hollow intermediate piece connecting the double-walled hollow leg and the single-walled leg, the cavities of the double-walled flange and the double-walled intermediate piece merge. Alternatively, the second leg can also be hollow. Optionally, only one leg can be hollow, the other leg and the spacer being single-walled.
    The invention furthermore relates in combination to a profile as described above as well as an L-shaped reinforcement which is received in the mutually merging cavities of the double-walled leg and of the double-walled intermediate piece. The combination can also consist of a U-shaped reinforcement accommodated in a correspondingly shaped cavity in the profile, or of a strip-shaped reinforcement also in a correspondingly shaped cavity. In particular, that profile may consist of aluminum or plastic and the reinforcement may consist of iron, such as steel.
    The invention will be explained in more detail below with reference to an exemplary embodiment shown in the figures.
    Figure 1 shows a horizontal section through a vertical profile of the grid.
    Figure 2 shows a horizontal section through the complete grid.
    Figure 3 shows a rear perspective view of the grid.
    Figure 4 shows a front perspective view of the grid as well as a construction with an opening on which the grid must be fitted.
    Figure 5 shows a horizontal section of a variant.
    Figure 6 shows a horizontal section of a further variant.
    The grid 1 shown in Figures 1-4 consists of the frame 22 and the slats 6. The frame 22 consists of the vertical profiles 2, 3 and the horizontal profiles 4 connecting them. The vertical profiles 2, 3 have a substantially L-shaped cross-section with hollow parts 27 and 28 .. The horizontally oriented slats 6 extend between these vertical profiles 2, 3, which are partially perforated as indicated at 7. The slats 6 each have head edges 8.9. Opposite each end face 8 and 9, there is a leg 10 in the hollow part 28 of the vertical profiles 2 and 3. Furthermore, each vertical profile 8, 9 has a leg 11 directed perpendicular to the first leg 10 in the hollow part 27, which extends over a portion of the slats 7. The parts of the slats 7 that are located near the end edges 8, 9 are therefore well protected behind these legs Π. Finally, each vertical profile 8, 9 has a single-walled flange 24 attached to the first leg 10 and parallel to the second leg 11. A U-shaped cross-section is thus formed, between which the ends of the slats are received. The slats 6 are thereby attached to the only other flange 24 by means of the rivets 25. On the outer periphery of the frame, the profiles 2-5 have a cover piece 23, which covers the surroundings of the opening 21 (see Figure 4).
    The L-shaped portion with the legs 10, 11 is double-walled, and encloses a cavity 12 consisting of the parts 27, 28. In this cavity 12 is the reinforcement 13, which also has an L-shaped cross-section with the legs 14 and 15. The leg 14 of the reinforcement is located in the hollow part 28 of the leg 10 of the profile 2,3 opposite the end edges 8, 9 in the leg 10 of the vertical profiles 2, 3, the leg 15 of the reinforcement 13 extends extends over the front side of the slats 6 and is located in the hollow part 27 of the leg 11 of a vertical profiles 2, 3.
    By means of the rivets 16 the leg 14 of the reinforcement 13 and the leg 10 of the vertical profiles 2,3 are attached to the anchoring strips 17. These strips 17 can in turn be securely fastened to the sides 19 and the top and bottom 18 of the structure 20, such as a part of a building, in which the opening 21 is located. After the grid 3 is firmly anchored to the structure 20, for example by means of bolts and the like inserted through the openings of the anchoring strips 17 and in the top and bottom or sides, respectively, the opening 21 is safe and burglar-resistant protected by the grid 3 This sturdy protection is formed by the L-shaped reinforcements 13 in these vertical profiles 2, 3, which ensure that the slats 6 are firmly incorporated in the grid. If the reinforcements are made of steel, the profiles 2, 3 can hardly be bent, if at all, such that forcing is excluded from the grid.
    The horizontal profiles 4, 5 can optionally be designed in the same way as the vertical profiles 2, 3, with an L-shaped reinforcement included therein. In the variant of Figure 5, a strip-shaped reinforcement 13 "is applied in the form of a single leg 15. This strip-shaped leg 15 is located in a correspondingly shaped cavity 12" with only the hollow part 27 of the vertical profile 2 ". Furthermore, this profile has a single-walled intermediate piece 23 and a single-walled leg 33. In this variant also, slats 6 lying behind the strip-shaped leg 15 and the strip-shaped reinforcement 13 "are protected.
    In the variant of Figure 6, the flange 24 is of double-walled design, such that the hollow part 27 thereof merges with the hollow part 28 of the intermediate piece 30 of the vertical profile 2 ". The reinforcement 13 'is now U-shaped and, in addition to the leg 15 and the intermediate piece 31, has a leg 26 which extends into the hollow part 29 of the double-walled flange 24. In this variant, the slats 6 are accommodated between the two flanges 11, 24 and the legs 15, 16 of the reinforcement 13 ".
