Definitions

• the present invention relates to a device for detecting the opening state of a door, a window or the like.
• Devices of this type are used in the private or commercial sector, especially for the purpose of object protection or intrusion detection.
• the object of the present invention is therefore to provide a device for detecting the opening state of a door, a window or the like. To create a unit that is both improved in terms of flexible and reliable usability and evaluation, and specifically enables the retrofitting of existing windows and doors with a reliable, easy-to-install system.
• the effect is exploited that the respective opening state can be determined by a specific position or movement detection of a locking bolt belonging to the window mechanism;
• a locking pin is equally a mechanical active element of the window or the door, and an indicator which is scanned and evaluated for determining the opening state within the scope of the present invention.
• the housing receiving the contactless sensor arrangement communicates with the associated base station in a self-sufficient, wireless manner.
• the present invention is thus ideally suited not only for use with a wide range of windows and doors (in whose profiles the unit is then suitably fitted), but also focuses on retrofitting security systems for doors and windows that have already been assembled , for which for the first time an inexpensive, low-maintenance, easy-to-install and significantly simplified monitoring system is available.
• the housing according to the invention is particularly preferred to assign the housing according to the invention to the fixed frame of a door or a window, in which case the locking bolt of the assigned window sash is suitably monitored in terms of its displacement or its position and then from this position or positional shift to an open state of the window or the door can be closed.
• sensor elements that are based on reed, magnetic field or the like are available for the individual sensors. work because here minimal power consumption can be combined with high contact quality, reliable switching behavior and insensitivity to weather and moisture.
• the present invention provides, in accordance with a preferred development, that a housing (preferably with a one-piece, elongated housing shell) accommodates all electronic and sensor components, so that not only optimal contamination and moisture protection can be achieved here , but also by simply attaching and screwing (more preferred: snapping or clipping) such a unit, the ready-to-use assembly can be carried out in a minimum of time and also by non-experts.
• a housing preferably with a one-piece, elongated housing shell
• accommodates all electronic and sensor components so that not only optimal contamination and moisture protection can be achieved here , but also by simply attaching and screwing (more preferred: snapping or clipping) such a unit, the ready-to-use assembly can be carried out in a minimum of time and also by non-experts.
• the present invention makes use of a pulse-based or packet-based radio transmission protocol, as described in the applicant's German patent application 100 17 182.6 and with regard to the generation, transmission and evaluation of the opening status signal or the opening status information as fully in the present Registration and should be considered as part of the invention.
• This further development makes it possible advantageously to achieve that with technologically extremely simple implementation and with minimized power consumption (particularly important in the case of a mains-free power supply), a highly secure and reliable connection of a special device to the base station can be achieved, with problems in radio transmission, problems in the power supply or the like. can be recorded reliably and at short notice, so that against the background of the field of application "monitoring and security technology" an optimal combination between practical handling and high transmission and monitoring security could be found.
• the present invention creates a possibility of achieving the integration of door and window monitoring into existing or planned security systems in a simple, flexible and ultimately also cost-effective manner, so that it can be expected that the object protection will be completely through the present invention new areas of application can be opened up.

• FIG. 5 shows a schematic representation of the device in the installed state in a window frame
• FIG. 8 an enlarged detail of detail VIII in FIG. 6. 1 illustrates an elongated housing 10, which is preferably formed as a plastic injection-molded part and has a typical length of approximately 160 mm, which, as is particularly clear from the longitudinal section in FIG - Housing section 16 and a flattened sensor housing section 18 located between the housing sections 14, 16 and opens on both sides into a flattened mounting flange 20 provided with a bore for a fastening screw.
• the housing 10 forms a flat surface area 22, above which a locking bolt 24 of a window or door leaf (cf. FIGS. 5 to 8) by means of an operating or.
• Locking lever 26 is movable and, depending on the position above the surface area 22, marks a respective opening state of the window or the door.
• a sensor element 28 realized as a reed contact is placed at predetermined positions A, B, C in the sensor housing section 18, in the present exemplary embodiment only the two outer positions B, C with sensor elements 28 are equipped.
• These sensor elements react in a contactless manner to the locking bolt 24 which can be moved above the surface area 22 in the operating state and change electrically evaluable sensor parameters, in particular when the locking bolt 24 faces a respective sensor element 28 through the housing surface 22.
• One in the housing section 16 recorded, suitably provided with an amplifier and Ausauswertlogik evaluation electronics evaluates the corresponding sensor signal and determines whether the locking pin is above one of the sensor elements 28, and then passes a corresponding position signal to a radio electronics also recorded in the housing section 16, the wireless and in accordance with the technology described in the applicant's German patent application 100 17 182.6 (in particular the implementation and the protocol used should form part of the present disclosure) radiates position information to a base station (not shown in the figures) via an antenna 30.
• an effective housing height can be realized which is in the range of approx. 10 mm (with a housing width in the range of approx. 20 mm), so that the arrangement shown in the embodiment can be easily fitted into existing window or door frame profiles , as shown schematically in Figures 5 to 8:
• FIG. 5 illustrates how an arrangement according to FIGS. 1 to 4 is fitted into a lower window frame area
• FIG. 7 schematically showing the housing 10 and the locking bolt 24 of the associated window sash 32 (in FIG. 7 in a central position)
• FIG. 6 shows the arrangement according to FIG. 5, but with the window sash open, so that here the locking bolt 24 has moved out of the surface area 22 (cf. FIG. 8).
• FIGS. 1 to 3 can be fastened in a particularly simple manner by means of the mounting flanges and simple screwing to an underlying (preferably fixed) frame section 2u, without further laying work for supply or signal cables being necessary, this indicates easily varied side view of FIG. 4 that in particular the housing 10 can also be fastened flexibly, type-specifically and detachably in a window or door unit by means of a snap connection with an adapter unit located between the actual window frame and the housing 10.
• a monitoring or security system for doors and windows can be realized in the shortest time, with the least assembly effort and with the greatest possible flexibility and adaptability to different profile and framework conditions, which is as insensitive to contamination and malfunction with high operational safety, more convenient Monitoring and simple maintenance properties combines.
