Description

State of the art

[0001] The invention is based on a burglar protection device according to the preamble of claim 1, and a method for temporarily protecting a wall opening according to the preamble of claim 14.

[0002] It has long been known that building elements such as doors or windows, which are generally less strong than the walls surrounding them, can be protected by burglar protection.

[0003] It is previously known that burglar protection comprises a protective element, such as a roller shutter, which is wound onto a winding shaft when opened. Such protective devices are disclosed, for example, in published patent application DE 102012 003 891 A1, utility model DE 203 17 556 U1, patent DE 10 2009 024 426 B3, patent DE 198 40 949 C1, published patent application DE 10 2005 038 007 A1, and published patent application DE 10 2015 117 548 A1. A disadvantage of this is the space required for winding the roller shutter.

[0004] Permanently installed external grilles are often used for windows. However, these have the disadvantage that these permanently installed grilles, which are often less aesthetically pleasing, cannot be used to secure doors. In the event of a fire, for example, an escape route for people in the building or an escape route for emergency services is blocked. To overcome these disadvantages, there are rolling grilles or scissor grilles that can be moved from a securing position to a non-use position when not in use. The disadvantage here is that, due to their design, rolling grilles or scissor grilles do not offer the desired resistance to burglars and are also prone to jamming.

[0005] In order to overcome this disadvantage, patent DE 195 31 040 C2 proposes a sliding shutter for a window or door element as a burglar protection device, wherein the sliding shutter has a grid-shaped or plate-shaped protective element, the size of which is adapted to the clear width of the wall opening belonging to the window or door element, wherein the protective element is suspended from a guide rail mounted above the window or door element and is horizontally displaceable parallel to the wall opening from a protective position covering the wall opening into an open position exposing the wall opening, and wherein the protective element, in the open position, is concealed in a receiving space mounted next to the window or door element, wherein the receiving space is recessed inside the wall defining the wall opening and the wall opening is reinforced at the edges with iron elements, wherein an electromagnetically actuated,A bolt is provided that can be inserted into the path of movement of the plate-shaped protective element, which blocks the protective element both in the open position and in the protective position and is mounted on both sides of the protective element in the blocking position. The bolt is automatically controlled by limit switches that are actuated by the protective element in the open position and in the protective position. The protective element can be moved either electrically via a rack and pinion or manually, and when manually moved in the open position, it is preloaded in the direction of the protective position by means of a spring. The design effort involved is considered a disadvantage. Another disadvantage is that the rigid, grid- or plate-shaped protective element, which has a frame, is usually quite heavy, which means that significant wear of the individual components due to its displacement cannot be ruled out.

[0006] The invention is therefore based on the object of providing a burglar protection device which overcomes the disadvantages of the prior art and a method for temporarily protecting a wall opening which overcomes the disadvantages of the prior art. The invention and its advantages

Description of the embodiment

[0025] Fig. 1 shows a side view of an inventive burglar protection device 1. The inventive burglar protection device 1 has a base frame 2 (cassette) on which masonry connectors (not shown) are arranged for connection to the masonry 3 shown in dashed lines. In addition, the base frame 2 is connected to a linear drive 4, which can be switched on and off by a switch 5, which is wired to the linear drive 4 via a cable 7 leading to a terminal box 6. When the linear drive 4 is switched on, spindles 8 (linear spindle guides) are rotated, causing the connecting cross member 10, which is connected to the spindles 8 via guide carriages 9, to move. Fixed to the connecting cross member 10 are protective elements in the form of grating bars 11, each of which is mounted in a counter-bearing flange 12 arranged on the base frame 2.When the connecting cross member 10 is moved in the direction of arrow 13, the grating bars 11 are each pushed through their counter-bearing flange 12, so that the grating bars 11, with their ends 14 facing away from the connecting cross member 10, are first pushed out of the base frame 2 (cassette). Thus, a protective element in the form of a grating bar 11 is moved from a first end position, which represents an open position for the protective element, to a second end position, which represents a protective position for the protective element, since in this second end position the protective element is located in front of a building element, such as a door or a window, in which the protective element (grating bar 11) is located for the most part outside the base frame 2 (cassette). In its second end position, the protective element (grating bar 11) is in contact with a strip 15 (counter-locking and centering strip), which is arranged on the masonry 3 using masonry connectors.

[0026] The burglar protection device 1 according to the invention is thus a burglar security device and has several motor-driven extendable and retractable protective elements (grille bars 11). The advantage over other burglar protection devices, such as roller shutters, is that windows or patio doors can remain open or tilted and burglar protection is still provided. Furthermore, the grille bars 11, which are preferably made of steel rods with a diameter of approximately 20 mm, can only be cut or bent using large technical equipment, which makes a burglary very difficult, complex, time-consuming and thus almost impossible. The protective elements (grille bars 11) are extended and retracted electronically via a motor-driven linear spindle guide using a switch 5 (OPEN / CLOSE switch), which is preferably located on the interior wall of the apartment / room.If there are several base frames 2 in a residential unit, they can also be connected and controlled via a smart home control system.

[0027] Fig. 2 shows a perspective view of a linear drive 4. A guide carriage 9 can be moved back and forth by the spindle 8.

[0028] The Fig. 3 and Fig. 4 show sketches of a first embodiment of an anti-burglary device 1 according to the invention. Fig. 3, the burglar protection device 1 according to the invention is shown in the open state, so that the bars 11 are located in the base frame 2 (cassette), which is firmly connected to the masonry and has a plasterable insulating mat 15. By actuating the switch 5, the bars 11 are electrically extended at least partially from the base frame 2 (cassette) to a position in Fig. 4, in which they have reached a counter-locking position 16, whereby a structural element 17 (e.g., window, door (e.g., sliding door)) is secured by the protective elements. Preferably, the spacing of the bars 11 is approximately 120 mm and has a diameter of approximately 20 mm.

[0029] The Fig. 5 and Fig. 6 show sketches of a second embodiment of an inventive burglar protection device 1. This embodiment, which is comparable to a surface-mounted roller shutter, wherein a burglar-proof steel housing 19 is used, is suitable for retrofitting if the masonry is not to be removed. Fig. 5, the burglar protection device 1 according to the invention is shown in the open state, so that the bars 11 are located in the base frame 2 (cassette), which is also firmly connected to the masonry 3 by means of internal anchors. By actuating the switch 5, the bars 11 are electrically extended at least partially from the base frame 2 (cassette) to a position in Fig. 6, in which they have reached a counter-lock 16 placed on the masonry 3, whereby a building element 17 (e.g. window, door (e.g. sliding door)) is secured by the protective elements.

[0030] The Fig. 7 and Fig. 8 show sketches of a third embodiment of an inventive burglar protection device 1. This embodiment is particularly suitable when building elements, such as windows or doors, are installed closer to the outer edge of the wall, so that an internal installation of the inventive burglar protection device 1 is expedient. Fig. 7, the burglar protection device 1 according to the invention is shown in the open state, so that the bars 11 are located in the base frame 2 (cassette). As in Fig. 7, the bars 11 are not visible from the outside, so that this may also have a visual advantage. By actuating the switch 5, the bars 11 are electrically extended at least partially from the base frame 2 (cassette) to a position shown in Fig. 8, in which they have reached a counter-lock 16, whereby a structural element 17 (e.g. window, door (e.g. sliding door)) is secured by the protective elements.

[0031] The Fig. 9 and Fig. 10 show a sketch of a plan view from the front of an inventive burglar protection device 1. For clarity, the insulating mat 16 has been omitted. The inventive burglar protection device 1 serves in this embodiment to protect a double-leaf patio door 20. A floor 21, a ceiling 22 and a lintel 23 arranged above the double-leaf patio door 20 are shown in sketch form. Fig. 9, the burglar protection 1 according to the invention is shown in the open state, so that the bars 11 are located in the base frame 2 (cassette), which is also firmly connected to the masonry 3 by means of internal anchors. By actuating the switch 5, the bars 11 are electrically extended at least partially from the base frame 2 (cassette) to a position in Fig. 10, in which they have reached a counter-lock 16 placed on the masonry 3, whereby the patio door 20 is secured by the protective elements.

[0032] Fig. Figure 11 shows another embodiment of an inventive burglar protection device 1 in the open state. In this embodiment, the inventive burglar protection device 1 has a telescopic threaded spindle 24.

[0033] Fig. 12 shows the burglar protection 1 according to the invention, according to Fig. 11, in the closed position. As in Fig. As can be seen in Figure 12, the telescopic threaded spindle 24 offers the advantage that the inventive burglar protection device 1 requires little space when opened, yet can still cover a large opening when closed. The telescopic threaded spindle 24, in which two spindles with opposing threads move, allows the extension distance to be almost doubled.

[0034] Fig. Figure 13 shows another embodiment of an inventive burglar protection device 1 in the open state. In this embodiment, a large double-leaf window 25 is to be secured. For this purpose, an inventive burglar protection device 1 is arranged to the left and right of the window 25.

[0035] Fig. 14 shows the burglar protection 1 according to the invention, according to Fig. 13, in the closed state. Preferably, the bars 11 coming from the left and right overlap in the middle, whereby a central stabilizing beam may also be present if necessary.

[0036] Fig. Figure 15 shows another embodiment of an inventive burglar alarm 1, in the open state. This embodiment, which can also be referred to as a vertical variant, takes into account a situation that occurs, for example, in apartment buildings, where there is insufficient wall space on either side of the window, but this space is available above or below the window or patio door.

[0037] Fig. 16 shows the burglar protection 1 according to the invention, according to Fig. 15, when closed.

[0038] Fig. Figure 17 shows an inventive burglar protection device 1, on whose bars 11 a printed sheet 26 is arranged. The sheet 26 offers the advantage of creating a different visual impression than the externally visible bars 11. The sheet can also be used for advertising, for example, in shops.

[0039] Fig. Figure 18 shows a decorative variant of an inventive burglar protection device 1. This takes into account that the bars 11 can also be provided with decorative elements 27 or ornaments 28 for aesthetic reasons. Counterflange bearings 29 arranged on the base frame 2 are adapted to the decorative elements 27 or ornaments 8, so that they have a different structure than the counterflange bearings 12.

[0040] As a further embodiment, it is also conceivable for the burglar protection device according to the invention to be arranged between, for example, two windows, wherein the base frame contains both bars that serve to protect one window and bars that serve to protect the other window. Preferably, the bars are arranged alternately in the base frame, so that the spacing between the bars in the base frame is approximately 60 mm.
