Definitions

  • the invention relates to a method for burglar protection of windows, doors, gates or the like.
  • Building openings or property entrances which from the outside by means of roller shutters, folding shutters, blinds, gate leaves, gate segments, rolling grilles or the like.
  • Covers are closable and a device for burglar protection by means of shutters, shutters, blinds, gate leaves, rolling grilles or the like.
  • Building openings or property entrances e.g. windows, doors, gates with e.g. horizontal segments
  • closable covers e.g. Mounted above the window, door or gate frame for the cover, such as a roller shutter or jalousie box or gate cutouts.
  • the invention has for its object to provide a method and a device of the type described in more detail above, whereby windows, doors, gates or the like. Building openings or property entrances as main break-in points are reliably secured against break-ins, both with closed roller shutters , Gates and the like. Covers as well as with open roller shutters or gates and the like, and what can be installed or implemented retrospectively in buildings that have already been completed, with low initial costs and without great effort.
  • this object is essentially achieved by the invention in that movement of the cover is detected at least when the building opening is covered or the property access is closed by means of at least one motion-sensitive sensor.
  • the method according to the invention offers reliable burglary protection, in which it indicates a potential burglary attempt as it arises, for example if an attempt should be made to open a folding shutter or a garage door that is folded in front of a window or a door.
  • the method according to the invention can also be easily implemented without great expenditure of time and money and is particularly suitable, in particular, for buildings or property entrances which have already been completed.
  • Another advantage is that, in contrast to the known burglar alarms, false alarms by animals in front of the covers, such as dogs or cats, are excluded, since an alarm is only triggered when a potential burglar tries to lift the cover, fold it away or, for example. in the case of access to the property, slide the cover into a floor-side shaft.
  • the method according to the invention also allows monitoring when the window, door or gate is only partially covered.
  • the outer opening or access front is monitored as a control level by means of at least one, possibly further, movement-sensitive sensor, preferably aligned in the control level.
  • at least one, possibly further, movement-sensitive sensor preferably aligned in the control level.
  • a single, appropriately aligned sensor can be used to detect a movement of the cover when the window, door or partially closed gate is covered or partially covered, and for monitoring when the cover is folded away, pulled up or also shut down.
  • a passive infrared motion detector can be used at least for the at least one sensor that detects movement of the cover, with a dual sensor for temperature compensation that has two sensor crystals of opposite optical polarity, the one sensor crystal being behind one as such Imaging system serving slit is arranged that this sensor crystal alone takes over the monitoring function and together with the second sensor crystal accomplishes the required temperature compensation.
  • a dual sensor for temperature compensation that has two sensor crystals of opposite optical polarity
  • the one sensor crystal being behind one as such Imaging system serving slit is arranged that this sensor crystal alone takes over the monitoring function and together with the second sensor crystal accomplishes the required temperature compensation.
  • the slit diaphragm leads to a blurred image, this has the advantage that small movements in the range between, for example, 1 to 2 cm do not yet trigger an alarm, since the signal values generated by these small movements are not sufficient to exceed a set alarm threshold . Only movements of the cover of, for example, 5 to 10 cm lead to reliable detection. This eliminates false alarms that could result from slight movements of the cover, for example as a result of weather influences.
  • the at least two sensors or motion detectors are expediently connected to a common alarm center, optionally provided with a switch for arming / disarming the two sensors or motion detectors and preferably designed as a changeover switch, and optionally with a siren
  • microswitches are used as the sensor or sensors.
  • At least one sensor for detecting the movement of the cover or its segments, at least when the building opening or the covered property access is covered is arranged in or near the receptacle.
  • the device according to the invention is protected from the weather by its arrangement on or near the receptacle for the cover and is secured against access from the outside, so that the burglar alarm cannot be switched off from the outside.
  • the assembly and operational safety of the device can be further improved according to the invention if the at least one sensor is held on a part of the receptacle on the inside of the building and is pressed against a e.g. upper section of the cover or against e.g. upper segment of the cover is directed.
  • the at least one sensor is arranged on or within the bottom-side receptacle and against a lower section of the cover or a lower one Segment of the cover is directed.
  • assembly is particularly simple if the at least one sensor is held on a rear wall of the receptacle inside the building and is directed towards the opposite segments located within the receptacle.
  • the at least one sensor which may be arranged in a metal sleeve, can be inserted from the outside through a bore in the rear wall of the receptacle and, if appropriate, is held in the bore with its metal sleeve. Subsequent assembly then only requires a hole to be made by means of a conventional drilling machine, into which the sensor is inserted. To the inside of the building, however, the receptacle or the roller shutter box remains unchanged, so that there is no change or special shapes of curtain rods or the like. requirement.
  • a burglar alarm around the clock can be achieved if, as provided for according to a further idea of the invention, at least one, possibly further, movement-sensitive sensor for monitoring the opening or access front, at least when the opening or access is not covered or near the receptacle, the beam path of which is preferably oriented essentially parallel to the opening or access front as a control plane.
  • the sensor which monitors the windows, door or gate front, for example when the roller shutters or rolling grilles are raised, is arranged on the inside of the building on or near the receptacle (protected from the weather) and is placed inaccessible from the outside of the building can, so that it cannot be put out of operation by a potential burglar.
  • the at least one motion-sensitive sensor can be arranged within the receptacle with a beam path extending through an opening of the receptacle for the entry and exit of the segments, so that the sensor is optimally placed outwards and inwards.
  • At least the at least one sensor that detects movement of the cover or its segments is designed as a passive infrared motion detector with a dual sensor having two sensor crystals of opposite optical polarity for temperature compensation, and a slit diaphragm is provided as the imaging system, which is arranged in front of the sensor or the motion detector such that one sensor crystal is congruent with the aperture of the slit diaphragm in the optical axis of the system, while the second sensor crystal is arranged outside the optical axis without direct visual contact with the cover or its segments, is preferably directed to the bottom of the receptacle.
  • Switching from one to the other sensor or motion detector for, for example, raised and lowered roller shutters is particularly easy in the case of a cover that can be actuated automatically, for example, can be raised and lowered, or retracted, when an automatic arming / disarming of the respective Sensor or motion detector by the control signals of the actuating device such that at, for example lowered cover of the sensor or motion detector which detects movement of the cover or its segments and in the case of e.g. the cover or sensor that monitors the opening or access front is in focus.
  • the at least two sensors or motion detectors of a common alarm center are connected, which, if appropriate, are equipped with a switch, preferably designed as a changeover switch, for manual arming / disarming of the two sensors or motion detectors and, if appropriate, with a siren is provided.
  • This alarm center can, for example, be mounted on the inside wall of the building behind a curtain and can also be designed as a sabotage line.
  • the burglar alarm 1 shows a burglar alarm 1 for a window 2, which can be closed from the outside of the building by means of a cover 3 designed as a roller shutter.
  • the cover 3 or the roller shutters is received in the raised state in a receptacle 11 which is embedded in the wall of the building above the window frame and is designed as a roller shutter box.
  • the burglar alarm 1 itself consists of two sensors 4, 5 designed as passive infrared motion detectors, each with a dual sensor type having two sensor crystals 6, 7.
