Definitions

  • the invention relates to a method for detecting a position of a closure element for a building opening, according to which at least one magnetic switch and at least one magnet are arranged on the closure element and a magnetic field is built up between the magnetic switch and the magnet.
  • the invention further relates to a fitting element for a closure element for closing a building opening, comprising a fitting element body which has a receptacle for a further fitting element of the closure element.
  • the invention relates to a closure element for closing a building opening comprising a fitting element.
  • Windows and doors of buildings are known to represent a weak point with regard to the burglar resistance of the building envelope. For this reason, a wide variety of more or less complex possibilities have been proposed in the past to make windows and doors of buildings more burglar-proof.
  • magnetic switches are also known in the prior art, which react when a magnet approaches. "Do-it-yourself systems", which are mounted on the frame and the casement, are known here.
  • the EP 0 478 834 A1 describes a device for reporting the open and closed position of a closable arrangement which has at least two elements movable relative to one another between the open and closed positions, in particular in the case of windows and doors, with a plurality of magnetic switches arranged on one of the elements in an electrical alarm line , of which at least one is actuated when the elements are closed by the magnetic field of an actuating magnet arranged on the other element to report the closed position, and an electrical series connection of the magnetic switches is provided, and at least one of the magnetic switches is a make contact and at least one other is a break contact, and only the closer is acted upon by the magnetic field intended to operate the switch in the closed position.
  • EP 1 856 355 A1 a window is known which is provided with a casement for enclosing a glass pane and with a window olive which has a handle fitting in which a handle is pivotably mounted and which has a module housing for receiving a monitoring and alarm module, the sensor devices and a Has evaluation unit, is equipped, wherein the module housing is arranged sunk in a recess of the sash.
  • the EP 0 468 514 A1 describes a locking device for a window, the sash frame is pivotably mounted on a frame, comprising a locking fitting to be arranged in an outer rebate circumferential surface of the sash frame with at least one locking pin that can be displaced in the circumferential direction of the rebate circumferential surface of the sash frame between a closed position and an open position, as well as a locking pin in an inner rebate circumferential surface of the window frame to be arranged strike plate part with an engaging recess for the locking pin that is open to the interior of the window frame and in the circumferential direction, the locking plate part being made of non-magnetic material, the locking pin carrying a permanent magnet and the locking plate part having at least one magnetic field sensor which is inserted in one of the side of the window frame the strike plate part is recessed and arranged from the engagement recess by an integral partition recess of the strike plate part.
  • the present invention is based on the object of specifying a possibility for an improved monitoring device for a window or a door.
  • the object of the invention is achieved with the method mentioned at the beginning, according to which it is provided that the magnetic switch is designed as an NO contact and the magnetic field is interrupted in the closed position of the closure element.
  • the object of the invention is achieved with the fitting element mentioned at the outset, in which at least one magnetic switch and at least one magnet are arranged in the fitting element body, the magnetic switch being designed as an NO contact.
  • the advantage here is that by using an NO contact as a magnetic switch, this cannot be bypassed from the outside with another magnet.
  • the built-in magnet can be bypassed by a (stronger) additional magnet that is brought to the magnetic switch from the outside.
  • the window that carries the monitoring magnet can be opened without the magnetic switch triggering an alarm message, as the additional magnet takes over the task of the magnet mounted on the window and causes the status "closed” even if the window is opened.
  • the change in status of the magnetic field takes place when the magnetic field is interrupted. The status change can therefore be brought about when the position of the closure element is changed from the “open” to “closed” state.
  • the design of the fitting element according to the invention also fulfills the requirements for combined opening and locking monitoring.
  • the magnetic switch is integrated into a fitting element belonging to the closure element, since the monitoring system can thus be more easily integrated into the closure element, and in particular can also be retrofitted more easily.
  • the at least one magnetic switch and the at least one magnet are completely integrated into the fitting element body of the fitting element.
  • the magnetic field is built up in just one element. This has the advantage that it is not necessary to check or readjust the monitoring after the closure element has been adjusted or readjusted (eg when correcting the position of a window sash), since this setting has no effect on the magnetic field of the monitoring.
  • wear and tear of the fitting components of the closure element over time does not have a negative effect on the monitoring device.
  • the complete integration can also ensure that it cannot be determined at a glance whether the Window has surveillance or not, which can increase the uncertainty factor in the case of a potential intruder.
  • a strike plate of the closure element is preferably used as the fitting element, since this offers a relatively large amount of space for the installation of the monitoring system.
  • the strike plate consists only of parts that do not move during use.
  • the power supply for the monitoring system can thus also be produced more easily, since the strike plate is usually attached to the frame, so that the power can be supplied via the wall and the frame.
  • this type of arrangement of magnet and magnetic switch simplifies the process, there is no additional work on the sash or a sash fitting of the closure element and no adjustments to the sash parts list are necessary.
  • the fitting element is a strike plate for a turn / tilt fitting.
  • the magnetic field is interrupted by a locking pin of the locking element.
  • the magnetic switch is connected to a data transmission device and / or power supply device which is arranged in a frame that has the Receives closure element.
  • a closure element 1 for a building opening in the form of an openable window is shown as an example. This illustration serves only to explain the invention.
  • the closure element 1 for the building opening can also be a door, in particular a terrace or balcony door or a lifting / sliding door.
  • Openable in the context of the invention means that the closure element 1 can be opened, that is to say, for example, it can be pivoted or tilted about a pivot axis. Accordingly, depending on the design of the fittings, the closure element 1 can be a sliding, swinging sash, turning, turning / tilting or tilting element.
  • the closure element 1 in the in Fig. 1 The embodiment variant shown comprises a sash frame 2 and a window frame 3. In the closed position of the closure element 1, the wing frame 2 lies against the window frame 3 in a sealing manner.
  • the closure element 1 can comprise a glass element 4 on which the casement 3 is arranged in the area of its outer circumference.
  • closure element 1 has various fitting elements 5, such as a window handle or rotary fittings, etc.
  • the sash frame 2 comprises several interconnected sash frame profiles 6 to 9, namely two vertical sash frame profiles 6, 8 and two horizontal sash frame profiles 7, 9, or consists of several sash frame profiles 6 to 9.
  • two of the sash frame profiles 6 to 9 can be glued to one another in the corner areas or, in particular, welded to one another.
  • the corner areas are cut with a miter, but can also be formed adjacent to one another at right angles.
  • the frame 3 can consist of a plurality of frame profiles 10 to 13 connected to one another or comprise them.
  • two of the frame profiles 10 to 13 can be glued to one another in the corner areas or, in particular, welded to one another.
  • the corner areas are cut with a miter, but can also be formed adjacent to one another at right angles.
  • closure elements 1 Since such designs of closure elements 1 are known from the prior art, reference is made to the relevant prior art in order to avoid repetition with regard to details.
  • the sash profiles 5-8 and the frame profiles 10-13 are preferably made of a plastic or wood.
  • a fitting element 5 of the closure element 1 is shown.
  • This fitting element 5 is in particular a strike plate (in Fig. 1 indicated by dashed lines), preferably for a turn / tilt window. It should be noted, however, that the fitting element 5 can also be another fitting element 5 of the closure element 1.
  • the fitting element 5 has a fitting element body 14. This can consist of a metal, in particular a non-ferromagnetic or non-magnetizable metal, or of plastic.
  • a recess 15 is formed in the fitting element body 14 which serves to receive a locking pin 16 of a further fitting element 5 of the locking element 1, as shown in FIG Fig. 2 is indicated by dashed lines.
  • the locking pin 16 can for example be operated with the aforementioned window handle or a door handle and moved from a locked to an unlocked position to open the locking element 1 (or vice versa from an unlocked to a locked position).
  • the locking pin 16 can, for example, have a mushroom-shaped end that the Recess 15 engages behind the surrounding edge of the fitting element body 14 in the locked position.
  • At least one magnet 17 and at least one magnetic switch 18 are arranged on it.
  • the magnet 17 and the magnetic switch 18 can be arranged at any suitable point on the closure element 1. It only has to be ensured that a magnetic field can be built up between the at least one magnet 17 and the at least one magnetic switch 18.
  • the at least one magnet 17 and the at least one magnetic switch 18 are arranged on a common fitting element 5, with the at least one magnet 17 and the at least one magnetic switch 18 being fully integrated in the fitting element 5 or its fitting element body 14 according to the preferred embodiment variant.
  • fully integrated is meant that neither the magnetic switch 18 nor the magnet 17 protrudes beyond the fitting element body 14, as shown in FIG Fig. 2 can be seen.
  • An electrical line 19, with which the magnetic switch 18 can be connected, for example, to an alarm center or a building management system, can of course project over or penetrate the fitting element body 14.
  • the magnetic switch 18 per se that is to say without the electrical line 19, however, does not protrude beyond the fitting element body 14.
  • the recess 15 can be made correspondingly larger so that the magnet 17 and the magnetic switch 18 can be received in this recess 15, as shown in FIG Fig. 2 can be seen.
  • the magnet 17 and the magnetic switch 18 can be arranged as individual elements on or in the fitting element 5. According to one embodiment variant of the invention, however, it can be provided that the at least one magnet 17 and the at least one magnetic switch 18 are arranged in a common housing 20. In the embodiment variant specifically shown, a total of two magnets 17 (one on the left and one on the right) are present. However, this is not to be understood in a restrictive manner.
  • this assembly can be prefabricated and inserted or installed with the housing 20 more easily in the fitting element body 14 or the closure element 1. It is thus also easier to retrofit existing closure elements 1, it being possible under certain circumstances to also replace the fitting element 5 that accommodates the housing 20.
  • the magnets 17 and the magnetic switch 18 can be arranged in the housing 20 such that a magnetic field can develop between these components.
  • the magnets 17 or the at least one magnet 17 are preferably designed as permanent magnets.
  • the at least one magnetic switch 18 can be a reed contact or a Hall sensor.
  • NO contact normally open
  • NO contact normally open
  • NO contact normally open
  • the magnetic field is built up between magnetic switch 18 and magnet 17. If the state is changed from “closing element 1 open” to "closing element 1 closed", the magnetic field is interrupted or disturbed, so that the magnetic switch 18 by interrupting or disturbing the magnetic field between the at least one magnet 17 and the at least one magnetic switch 18 is switched.
  • the magnetic field interruption or disturbance is therefore in the closed position of the closure element 1, in particular caused by the locking pin 16, which in the preferred embodiment of the invention when the closure element 1 is closed in the recess 15, in which preferably also the at least one magnet 17 and the at least one magnetic switch 18 is arranged, penetrates.
  • the magnetic switch 18 is connected to a data transmission device 21 and / or power supply device which is arranged, for example, in the frame 3.
  • the power supply device can be, for example, an accumulator.
  • the data transmission device and / or power supply device can also be installed externally in another accommodation (for example a flush-mounted socket).
  • the described status monitoring system of the closure element 1 can be used to prevent break-ins.
  • the status message of the system can also be used for other applications, for example for switching the heating (switch off when locking element 1 is open, switch on when locking element 1 is closed) or switching room ventilation (off when locking element 1 is open, on when locking element 1 is closed) , etc ..
  • a delay in the switching of further devices, such as the heating, can be provided so that not every brief status change causes the switching in the further device.
  • Every circuit can be switched with a relay or every circuit for which voltage the Lock monitoring is designed, can be switched directly without a relay.
  • the at least one magnet 17 and the at least one magnetic switch 18 are arranged in close proximity to one another.
  • the distance between the magnet 17 and the magnetic switch 18 is between 0 mm and 5 mm, in particular between 0 mm and 3 mm. It is more preferred, as in FIG Fig. 2 is shown when the locking pin or a locking bolt does not have to be inserted between the magnetic switch 18 and the magnets. It can therefore be sufficient if the magnetic field formed between the magnetic switch 18 and the magnet 17 is only disturbed but not interrupted, so that the magnetic switch 18 switches solely on the basis of this magnetic field disturbance.
  • the exemplary embodiments show or describe possible design variants of the closure element 1, with combinations of the individual design variants with one another also being possible.
