Energy-autonomous systems are used in the field of building automation, for example in installation switches and window and door handles. Energy self-sufficient systems are characterized in that the system comprises an electrical energy generating device and thus requires no power connection, whereby connections and lines can be saved. Such an energy generating device may be, for example, a solar cell, a piezoelectric transducer, an inductive transducer or the like. Such power generators are advantageous in that the energy required for power generation can be taken from the environment or from a required for operating the installation switch or the window or door handle mechanical energy, so this type of energy converter is independent of battery capacity and maintenance.

Such energy self-sufficient systems are used in connection with condition monitoring mainly based on radio-bound solutions. The radio-bound solutions have the advantage that a complex wiring can be omitted.

For example, the document discloses EP 1 838 941 B1 an energy self-sufficient radio solution for an actuating handle having an inductive transducer-based device with the above-mentioned features.

The support element preferably has an outer dimension corresponding to the tub interior of the open tub, as a result of which the support element can cover the open tub outside the passage area when in the contact state. The Carrier element thus forms a cover for the housing. The housing interior or the components received in the housing interior can be protected thereby more effectively against external influences.

In accordance with a further preferred embodiment, the device has an actuating adapter element which can be connected in a rotationally fixed manner to the actuating bolt and can be received by the second receiving section, which forms the at least one outer edge on the circumference of the actuating bolt.

The individual positions of the actuating handle preferably correspond to functional positions of, for example, a window or a door, such as an open position, a closed position or a tilted position. In this way, a predetermined position of the actuating handle can be detected in a simplified manner, forwarded to the radio transmitter module and transmitted wirelessly via the radio transmitter module to a receiver, for example a condition monitoring device. The position detection device is thus suitable for using an electrical energy generated by the energy converter for detecting the position of the actuating handle.

Alternatively, the electronic components forming the radio transmitter module can be distributed on at least two printed circuit boards. Preferably, the one circuit board comprises only the radio transmitter antenna, while the remaining electronic components of the radio transmitter module are arranged on the second circuit board, which can be received in a further receiving portion of the housing and electrically coupled to the energy converter in particular via plug contacts. The first and second circuit boards are preferably electrically coupled to each other by means of a plug contact. Alternatively or additionally, other electrical couplings such as electrical lines, grinding or clamping contacts may be provided. As a result, a modular construction of the device is favored, whereby in a defect case only the circuit board carrying the defective component needs to be exchanged. The printed circuit board can be a commercially available printed circuit board, a stamped grid, a metal-plastic composite or another contact system. The radio transmitter module may be a radio transmitter module for bidirectional communication with a radio receiver module.

Further preferably, the contact portions and the common contact portion are each formed by sliding contact surfaces, wherein the first and second contact are formed by protruding from the contact element sliding contact fingers.

The actuation handle is preferably a preferred actuation handle as described above. The method includes a step of rotating the at least one outer edge from an initial position toward an end position via an actuation position operatively actuating the energy converter. The starting position may be one of the above-described functional positions of the actuating handle, the end position preferably being a different functional position of the actuating handle. Further preferably, the actuation position may be identical to the end position or alternatively lie between the starting position and the end position. The rotation step comprises a sub-step of generating an electrical energy by means of the energy converter, a subsequent sub-step of generating a radio transmission telegram with information about the actuation of the actuation handle and a subsequent sub-step of sending the radio transmission telegram. The generation and transmission of the radio transmission telegram is effected by means of the radio transmitter module, which has at least suitable electronic components and a radio transmitter antenna. The electronic components preferably form at least one logic and one radio module.

The method allows a cost-effective, self-sufficient and maintenance-free state query for a compact formable actuating handle.

Preferably, the energy converter is formed monostable for the process. Monostable corresponds to a further energy production by the energy converter without further actuation of the switching element. This can be realized, for example, by means of a spring device forming the switching element, which is configured in such a way that it automatically resets itself to the starting position after actuation, whereby further energy is generated in the energy converter. Alternatively, the energy converter is preferably formed bistable. Bistable corresponds to a further energy generation by the energy converter preferably by means of an actuation of a further in the rotational path of the at least one outer edge projecting switching element. This can be realized, for example, by an actuatable return spring coupled to the energy-generating components of the energy converter, which forms a further switching element which can be introduced into the rotary path of the outer edge after actuation of the switching element, which remains outside the rotary path of the outer edge after actuation thereof until a renewed actuation of the switching element , In the case of the monostable or bi-stable energy converter, the method preferably has further substeps associated with the rotation step and following the substep of the transmission in the order of regenerating an electrical energy by means of the energy converter and repeatedly sending the radio transmission telegram.

In addition, a higher frequency of transmission can be ensured, whereby a better transmission reliability can be achieved.

Alternatively, in the case of the monostable or bistable design of the energy converter, the method preferably comprises further substeps associated with the rotation step and following the substep of the transmission in the order of regenerating an electrical energy by means of the energy converter, generating a new radio transmission telegram and sending the new one Radio transmission telegram on. As a result, improved system security, in particular tamper resistance, can be achieved.

In accordance with a further preferred embodiment of the method, the actuating handle comprises an electrical position detection device as described above for electrically detecting a position of the actuating handle, wherein the rotation step precedes the substep of generating the radio transmission telegram by closing a contact bridge associated with a position of the actuating handle to detect the position of the actuating handle wherein the information of the radio transmission telegram includes information about the detected position of the operation handle. The detection of the position of the actuating handle can be carried out by means of a query or signal evaluation, for example by a logic device, in particular the radio transmitter module, wherein the sub-step of the query or signal evaluation follows the sub-steps of closing and generating an electrical energy, wherein the step of closing the contact bridge preferably for the sub-step of the query preceded by the sub-step of generating an electrical energy and for the sub-step of the evaluation is the sub-step of generating an electrical energy below. The latter already favors automatic signal transmission to the logic module when the contact bridge is closed.

More preferably, the energy converter monostable or bistable designed for the process and the actuating handle equipped with an electrical energy storage, wherein the rotation step one between the substep of generating a sub-step of storing a surplus electrical energy and preferably a sub-step following this sub-step of regenerating an electrical energy by means of the energy converter has a radio transmission telegram and the sub-step of sending the radio transmission telegram. As a result, an improved higher energy availability can be ensured, for example for complex radio protocols. The energy store is preferably arranged on a printed circuit board carrying at least one electronic component of the radio transmitter module.

Further preferred for the method, besides the monostable or bistable design of the energy converter, the radio transmitter module is designed for bidirectional communication with an associated radio receiver module, wherein the rotation step further sub-steps subsequent to the sub-step of sending in the order of generating a new radio transmission telegram after receiving a radio confirmation telegram from the Radio receiver module and the sending of the new radio transmission telegram, wherein a substep of re-generating an electrical energy by means of the energy converter preceded by the sub-step of generating a new radio transmission telegram or between the substep of generating a new radio transmission telegram and the substep of sending a new radio transmission telegram. This can ensure improved system security.

The above-described preferred embodiments of the actuating handle, the device and the method are particularly suitable for window or door handle monitoring systems, whereby a change or a manipulation of the actuating handle can be monitored. For example, the preferred embodiments may be used in conjunction with a security system for monitoring and securing a window or door. In addition to a preferred embodiment of an actuation handle, the safety system can include a solar energy converter for converting light energy into electrical energy with an energy store, in particular a rechargeable battery for storing the generated electrical energy. The solar energy converter can be arranged, for example, directly in the glass pane. Furthermore, the security system comprises a Vibration sensor and / or a sound transducer device such as a microphone for monitoring the window or the door for signaling an improper opening or damage to the window or the door. For this purpose, the security system further comprises a signal processing device with a radio transmitter module which can process the signal received from the vibration sensor or the acoustic transducer device and send a radio transmission telegram with information about an inadmissible opening or damage by means of the radio transmitter module. The signal processing device is coupled to the solar energy converter for supplying electrical energy.

The carrier element 50 carries a radio transmitter antenna 54, which can be coupled to a radio transmitter module for the wireless transmission of a radio signal. For this purpose, the carrier element 50 is formed as a printed circuit board. The arrangement of the radio transmitter antenna 54 on the carrier element 50 enables a reliable emission of the radio signal and, in the case of a design of the radio transmitter module for bidirectional communication, reliable reception of a corresponding radio signal. The surface provided with the carrier element 50 can therefore be optimally utilized for the radio transmitter antenna 54.
