The disclosure relates to a device for an actuation handle, in particular an energy self-sufficient device for detecting at least one actuation, more preferably an actuation direction of the actuation handle, and furthermore preferably, a position of the actuation handle, as well as to a wireless transmission of a signal having data regarding the detected actuation, actuation direction, or actuation position. Furthermore, the present disclosure relates to such an actuation handle and a method for the wireless transmission of an energy self-sufficient generated signal by means of an actuation handle.
Energy self-sufficient systems are used in the field of building automation, e.g. in installation switches and window and door handles. Energy self-sufficient systems are distinguished in that the system comprises a device that generates electric energy, thus requiring no electrical connection, as a result of which, connectors and wiring can be eliminated. Such an energy generating device can be a solar cell, a piezoelectric transducer, an inductive transformer, or suchlike. Such energy generators are advantageous in this regard, in that the energy required for generating electricity can be taken from the environment or from mechanical energy necessary for actuation of the installation switch or the window or door handle, whereby this type of energy converter is independent of battery capacities and maintenance measures.
Such energy self-sufficient systems are used in conjunction with status monitoring, primarily based on radio signal solutions. The radio signal solutions have the advantage that there is no need for a complex wiring.
By way of example, EP 1 838 941 B1 discloses an energy self-sufficient radio solution for an actuation handle, with a device based on an inductive transformer having the features specified in the preamble.
Additionally, a uniform handle design has been established in the field of window and door handles, which is composed of a standardized housing and a uniform interface to a locking mechanism. The interface is usually formed by a square bolt, which is non-rotatably coupled to a handle piece, and engages with its free end in the locking mechanism. The housing has attachment means thereby, for the attachment thereof to the window frame or to the door.
Independent of the exterior design, there is increasing interest in self-sufficient radio systems, which are capable of transmitting complex radio protocols such as KNX-RF, ZigBee, Bluetooth Low Energy or W-LAN with a higher transmitting power and with numerous repetitions. High demands are also placed on the data transfer reliability. Furthermore, the self-sufficient radio system should also offer the possibility of easily retrofitting already existing solutions.
With the present disclosure, a device is to be provided for an actuation handle that fulfills at least one, preferably all, of the demands specified above. In particular, the device should be economical and function in an energy self-sufficient manner, without the need for maintenance.

The actuation handle is preferably a rotatable handle piece, in particular a window handle or a door handle.
The device comprises a housing, having a first receiving section for receiving an energy converter for supplying a radio transmitter module with electricity by converting mechanical energy into electrical energy. In other words, the electrical energy generated by the energy converter is used by the radio transmitter module, in particular, for the generation and wireless transmission of a radio signal.
The housing furthermore has an aperture. The aperture has a second receiving section for rotatably accommodating the section of the actuation bolt having the at least one outer edge. The aperture preferably extends in the direction of the aperture at least along the second receiving section. Thus, other elements, disposed outside the second receiving section, can be allocated to the aperture. The actuation bolt can be inserted into the aperture, and extends along the aperture direction, or the insertion direction, respectively, beyond the aperture on at least one side, preferably on both sides, when in a functional connection with the device.

In this context, switch-effecting means that the energy converter converts a mechanical energy applied to the switch element by the at least one outer edge into electrical energy, by means of the switch-effecting actuation of the switch element. The energy converter is preferably an inductive transformer. The energy converter is furthermore preferably a component of the device. It is further preferred that the energy converter has a soft magnetic or magnetizable element, and a permanent magnet, which are disposed such that they can be moved in relation to one another by means of the switch element.

The stationary and moving components are designed such that a temporal change to the magnetic flux, or a magnetic flux reversal is caused in the assembly by means of the relative movement, which causes, respectively, a generation of an induction voltage in the coil. The switch element is preferably a spring element or a spring mechanism thereby, which is designed for transferring the mechanical energy transmitted from the at least one outer edge to the moving component of the assembly by moving it. It is furthermore preferred that the switch element is designed to first store the mechanical energy transmitted from the at least one outer edge, and when a switchover point has been reached, to transfer this mechanical energy to the moving component of the assembly. It is further preferred that the energy converter is an induction generator in accordance with DE 10 2011 078 932 A1. This energy converter is advantageous in this regard, in that a significantly larger electrical energy yield can be obtained in comparison with other previously known inductive converters.
The second receiving section is preferably designed such that at least one section of the actuation bolt can be received by a section of the at least one outer edge that is sufficient for a switch-effecting actuation of the energy converter. The second receiving section, in other words, is preferably designed in relation to the outer dimensions of the section having at least one outer edge, such that it can receive, entirely or in part, a section of the actuation bolt having the at least one outer edge. The second receiving section preferably extends between opposing aperture holes in the direction of the aperture, through which the actuation bolt can be passed through the housing when said housing is being installed. It is further preferred that the second receiving section has an external size corresponding to an outer size of the section having the at least one outer edge in the same direction, in a direction orthogonal to the aperture direction.
The proposed device can have a more compact design as a result of the direct actuation of the energy converter by means of an outer edge provided on the actuation bolt. As a result, the housing can be adapted to the standardized design of a standard handle. The device is energy self-sufficient as a result of the energy converter, and designed such that it does not require maintenance. On the basis, for example, of a use of the previously known energy converter described above, energy demanding radio protocols can be easily implemented.
The actuation bolt is preferably designed as a multi-sided bolt. It is further preferred that the actuation bolt is formed by a square pin previously known from the range of standard handles. Thereby, at least one of the edges running on the outside of the actuation bolt in the direction of the longitudinal axis forms the at least one outer edge. It is further preferred that more than one of the edges running along the outside of the actuation bolt in the direction of the longitudinal axis form an outer edge that is suitable for a switch-effecting actuation of the energy converter.

The projection can have any shape thereby that is suitable for a switch-effecting actuation of the energy converter. In particular, the at least one outer edge or the projection forms a peak in terms of its cross section, which travels along a preferably circular path during the rotational movement of the actuation bolt, which is crossed by the switch element, in particular a punctiform or planar actuation element of the switch element. During a rotational movement of the actuation bolt, the switch element ends up bearing on the outer edge, or the projection, respectively, and is carried, or moved, by the outer edge, or the projection, respectively, from an initial position of the switch element to at least a switching position of the switch element, for a switch-effecting actuation of the energy converter.
Further preferred embodiments of the present disclosure are the subject matter of the dependent claims.
According to a preferred embodiment, the housing has a pan-like section, which forms the first receiving section and the aperture having the second receiving section, wherein the aperture has an aperture hole formed in the pan base in the direction of the aperture. A single space is created by this means, which can be covered, or more preferably, sealed, with respect to an outer surface of the housing, for protection against external effects.
It is further preferred that the housing forms a pan that is open on one side, which comprises the pan-like section. The housing can have a simple and compact design as a result. At least some of the housing walls forming the open pan can be used to form the pan-like section thereby.
The housing preferably has attachment means outside the pan-like section for attaching the housing to a wall provided for attaching the actuation handle. This wall can be a part of a window frame or a door, for example. It is further preferred that attachment pins on a side of the housing, protruding therefrom, form the attachment means, which are designed to engage with the actuation recesses formed in the wall provided for attaching the actuation handle. The device can thus be installed at an attachment location for the actuation handle, making use of the existing attachment means.
It is further preferred that the housing has further attachment means for attaching the actuation handle to the housing on a side of the housing having the pan-like housing section, wherein the further attachment means are disposed outside the pan-like housing section. As a result, the device can be installed on the actuation handle, and between the actuation handle and the wall provided for attaching the actuation handle. For this, the actuation handle preferably has a rosette, which can be connected to the housing via the further attachment means. A rosette is normally used for covering attachment means for the actuation handle and/or for attaching the actuation handle. The rosette furthermore optically separates the actuation bolt from an actuation section such as a handle piece for example. The rosette furthermore preferably has counter-attachment means allocated to the other attachment means, which can be brought into engagement therewith. Any connecting means may be considered for the attachment means and counter-attachment means that can form a releasable or non-releasable connection between two components. By way of example, screw, snap-in, adhesive and/or rivet connections can be used.
The housing is preferably made of plastic, more preferably an injection molded plastic. It is furthermore preferred that the housing, having the pan-like section, the attachment means and the further attachment means is formed as an integral unit. The housing can thus be produced in an economic manner.
It is further preferred that the housing has a bearing section for resting on a carrier element having at least one radio transmission antenna, which covers a section of the pan-like section encompassing at least the aperture when it is resting on the housing. In other words, the carrier element has a through-hole for the actuation bolt corresponding to or smaller than the outer dimensions of the aperture, wherein the through-hole is formed such that it is coaxial to the aperture when the it is resting on the carrier element. The bearing is preferably formed by front surface ends of the housing walls encompassing the pan-like section. Alternatively or additionally thereto, the bearing is preferably formed by front surface ends of inner housing walls, which are disposed inside the outer housing walls forming the open pan, wherein the front surface ends of the inner housing walls exhibit a smaller spacing to the pan base than the front surface ends of the outer housing walls. As a result, the carrier element comes to bear on the housing between the outer housing walls, by means of which a more compact design of the device can be obtained. The carrier element preferably has an external size corresponding to the space inside the open pan, by means of which the carrier element can cover the open pan outside the aperture region when in the bearing position. The carrier element thus forms a cover for the housing. The housing interior, of the components received in the housing interior, respectively, can be effectively protected against external influences as a result.
According to another preferred embodiment, the device has an actuation adapter element that can be non-rotatably connected to the actuation bolt, and can be received in the second receiving section, which forms the at least one outer edge on the circumference of the actuation bolt. As a result, the device can be adapted to existing solutions, which have an actuation bolt without at least one outer edge, or have a cross section that is too small for a switch-effective actuation of the energy converter.
The actuation adapter element preferably comprises a bore-hole, through which the actuation bolt can be inserted. The bore-hole preferably forms a negative of the cross-section of the actuation bolt. It is further preferred that an inner contour or inner dimensions of the bore-hole corresponds to an outer contour or outer dimensions of the actuation bolt. The actuation adapter element can thus be disposed on the actuation bolt via a punctiform or planar press fit.
Alternatively or additionally, the actuation adapter element can preferably be connected to the actuation bolt via an adhesive connection, a screw connection, a clamping connection or similar connections.
Furthermore alternatively or additionally, the actuation adapter element preferably has a stand, more preferably a base plate, from which the at least one outer edge extends, wherein the stand can be received in the aperture hole such that it can rotate. The stand preferably has an outer contour corresponding to the inner contour of the aperture hole. The outer contour and the outer dimensions of the base are preferably selected such that an unobstructed rotational movement of the stand in the aperture hole is possible.
It is furthermore preferred that stand can be retained in the aperture hole, at least in a direction parallel to the direction of the aperture hole, such that it cannot be lost. By way of example, this can be implemented via a bearing of the stand on a section of the housing base delimiting the aperture hole, acting in the direction of the aperture hole. It is further preferred that the stand is retained such that it cannot become lost in opposing directions, parallel to the direction of the aperture hole. By way of example, this can furthermore be implemented by at type of tongue-and-groove system in the aperture hole, between the stand and the housing base.
As a result of the stand, there is no need for an attachment of the actuation adapter element to such an actuation bolt, for example, having at least one outer edge or one outer projection. The actuation element is merely designed in this manner in order for the actuation element to be able to be guided by the actuation bolt during a rotational movement. This can be implemented, for example, via an engagement between the existing outer edge or the projection protruding from the outer surface of the actuation bolt with an inner surface of the actuation adapter element delimiting the bore hole.
According to another preferred embodiment, the device has a position detection device that can be coupled to the energy converter and the radio transmission module, for an electrical detection of a position of the actuation handle. The position detection device furthermore comprises an encoding element that can be non-rotatably coupled to the housing, and can encompass the actuation bolt, and an electrically conductive contact element that can be non-rotatably coupled to the actuation bolt. The encoding element can be electrically coupled to the energy converter, and has at least one electrically conductive contact bridge allocated to a position of the actuation handle that can be assumed, which can be switched between an open, electrically non-conductive state and a closed, electrically conductive state, by means of the electric contact element, wherein different positions of allocated contact bridges are insulated from one another, wherein, when a predetermined position of the actuation handle is assumed, the at least one contact bridge allocated to the position is switched to the electrically conductive state, or closed, while the other contact bridges are switched to the electrically non-conductive state, or are open. The individual positions of the actuation handle preferably correspond to functional positions of a window or door, for example, such as an open position or a closed position, or a tilted position. In this manner, a predetermined position of the actuation handle can be detected simply, transmitted to the radio transmission module, and transmitted wirelessly via the radio transmission module to a receiver, such as a status monitoring device, for example. The position detection device is thus designed to use an electrical energy generated by the energy converter for detecting the position of the actuation handle. Furthermore, the position detection device is designed to transmit data regarding the detected position to the radio transmission module by means of an electrical signal, wherein the radio transmission module processes this signal for a wireless transmission of the data.
The encoding element preferably has a contact section for each of the positions the actuation handle can assume, and a further collective contact section, electrically insulated from these contact sections, and disposed concentrically thereto, wherein the contact sections allocated to the different positions of the actuation handle are electrically insulated from one another. An electrically conductive contact bridge is thus formed by one contact section and the collective contact section.
The contact element preferably has at least one first contact for establishing an electrically conductive contact to the collective contact section, and one second contact, coupled in an electrically conductive manner to the first contact, for establishing an electrically conductive contact to one of the contact sections, depending on a position of the actuation handle. In this manner, the at least one electrically conductive contact bridge allocated to a predetermined position of the actuation handle can be switched between the open and closed state, depending on the position, or functional position, of the actuation handle.
It is further preferred that the encoding element is disposed on a printed circuit board. The printed circuit board furthermore preferably forms the carrier element having the radio transmission antenna. It is further preferred that the radio transmission module is disposed on printed circuit board. In this manner, the entire electronics system for detecting the position of the actuation handle as well as for a wireless transmission of a signal containing data regarding the detected actuation, in particular regarding the detected actuation direction and/or position of the actuation handle, can be accommodated on a printed circuit board. Preferably the electronic components forming the radio transmission module are disposed on a side of the printed circuit board facing away from the encoding element, wherein the housing has a receiving section for the electronic components. In this manner, the electronics can be provided on an inner surface protected against the outside of the device. Alternatively, the electronic components forming the radio transmission module can be provided such that they are divided between two printed circuit boards. The one printed circuit board preferably comprises only the radio transmission antenna, while the other electronic components of the radio transmission module are disposed on the second printed circuit board, which can be received in another receiving section of the housing, and can be coupled to the energy converter, in particular via plug-in contacts. The first and second printed circuit boards are preferably electrically coupled to one another by means of a plug-in contact. Alternatively, or additionally, other electronic couplings, e.g. electrical lines, sliding contacts or clamping contacts may be provided. As a result, a modular construction of the device is favored, wherein only the printed circuit board with the defective component needs to be replaced in the event of a malfunction. The printed circuit boards can be conventional printed circuit boards, a lead frame, a metal-plastic composite, or some other contact system. The radio transmission module can be a radio transmission module for bidirectional communication with a radio receiver module.
It is further preferred that the contact sections and the collective contact section are each formed by sliding contact surfaces, wherein the first and second contacts are formed by the sliding contact finger protruding from the contact element. In this manner, an electrically conductive sliding contact, depending on the position of the actuation handle can be produced between the contact element and the encoding element, in particular between the first or second contact and the corresponding contact sections assigned thereto. As a result, an economical and simply designed position detection device can be created.
According to another aspect of the present disclosure, an actuation handle is proposed. The actuation handle comprises a handle piece, an actuation bolt rotatably coupled to the handle piece, a device as described above, an energy converter for converting mechanical energy to electrical energy, and a radio transmission module coupled to the energy converter for a wireless transmission of a radio signal, wherein the energy converter supplies the radio transmission module with the electrical energy that has been generated. The actuation bolt is intended to engage in a locking or opening mechanism at its free end. The actuation handle is preferably a window or door handle, wherein the free end of the actuation bolt is designed to engage with a mechanism for closing and opening the window or door provided with the window or door. In this manner, an actuation handle complying with the requirements described in the introduction can be created.
In accordance with another aspect of the present disclosure, a method for a wireless transmission of an energy self-sufficient generated signal by means of an actuation handle is proposed, wherein the actuation handle comprises a rotatable actuation bolt having at least one outer edge, into the rotational path of which a switch element for an energy converter for converting mechanical energy into electrical energy extends, such that a rotational movement of the actuation bolt results in a switch-effecting actuation of the energy converter by means of an actuation of the switch element by the outer edge, wherein the generated electrical energy supplies a radio transmission module electrically coupled to the energy converter for a wireless transmission of the radio signal. The actuation handle is preferably a preferred actuation handle, as described above. The method comprises a step for rotating the at least one outer edge from a starting position toward an end position via an actuation position that actuates the energy converter in a switch-effecting manner. The starting position can be one of the functional positions of the actuation handle described above, wherein the end position is preferably a different functional position of the actuation handle. It is further preferred that the actuation position can be identical to the end position, or alternatively, it can lie between the starting position and the end position. The rotational step comprises a sub-step for generating an electrical energy by means of the energy converter, a subsequent sub-step for generating a radio transmission telegram containing data regarding the actuation of the actuation handle, and a subsequent sub-step for transmitting the radio transmission telegram. The generation and transmission of the radio transmission telegram occurs by means of the radio transmission module, having at least electronic components suitable for this, and a radio transmission antenna. The electronic components preferably form at least one logic module and one radio module.
The method enables an economical, self-sufficient and maintenance-free functioning status query for an actuation handle that can have a compact design.
Preferably, the energy converter is designed to be mono-stable for the method. Mono-stable means that it can generate further energy by means of the energy converter, without further actuation of the switch element. This can be implemented, for example, by means of a spring element forming the switch element, which is designed such that it automatically returns to the starting position after an actuation, by means of which a further generation of energy occurs in the energy converter. Alternatively, the energy converter preferably has a bi-stable design. Bi-stable means that further energy is generated by the energy converter, preferably by means of an actuation of a further switch element protruding into the rotational path of the at least one outer edge. This can be implemented with an actuatable reset spring, for example, coupled to the energy generating components of the energy converter, which forms another switch element that can be placed in the rotational path of the outer edge after actuation of the switch element, which remains outside of the rotational path of the outer edge after it has been actuated until the switch element has been actuated again. The method, in the case of the energy converter designed to be mono-stable or bi-stable, has further sub-steps, preferably allocated to the rotational step, following the transmitting sub-step, sequentially generating an electrical energy again by means of the energy converter, and a repeated transmission of the radio transmission telegram. As a result, an energy demanding radio protocol, for example, can be transmitted. In addition, a higher transmission frequency can be ensured, by means of which better transmission reliability can be obtained.
Alternatively, in the case of the energy converter being configured as mono-stable or bi-stable, the method has further sub-steps, allocated to the rotational step, following the transmission sub-step, sequentially generating electric energy again by means of the energy converter, generating a new radio transmission telegram, and transmitting the new radio transmission telegram. As a result, improved system reliability, in particular a manipulation reliability, can be obtained.
According to a preferred embodiment of the method, the actuation handle comprises an electric position detection device, as described above, for electrically detecting a position of the actuation handle, wherein the rotational step contains a sub-step for closing a contact bridge assigned to a position of the actuation handle for detecting the position of the actuation handle upstream of the sub-step for generating the radio transmission telegram, wherein the data in the radio transmission telegram contains data regarding the detected position of the actuation handle. The detection of the position of the actuation handle can occur, for example, by means of a query, or a signal evaluation, e.g. by means of a logic module of the radio transmission module, in particular, wherein the sub-step for the query or signal evaluation follows the sub-steps for closing and for generating an electrical energy, wherein the step for closing the contact bridge is preferably before the sub-step for querying the sub-step for generating an electric energy, and follows the sub-step for evaluating the sub-step for generating an electric energy. The latter already favors an automatic signal transmission to the logic module when the contact bridge is closed.
It is further preferred for the method that the energy converter has a mono-stable or bi-stable configuration, and the actuation handle is equipped with an electrical energy storage unit, wherein the rotational step has a sub-step for storing excess electrical energy provided between the sub-step for generating a radio transmission telegram and the sub-step for transmitting the radio transmission telegram, and preferably has a sub-step following this sub-step, for the renewed generation of electrical energy by means of the energy converter. As a result, an improved, higher energy availability can be ensured, e.g. for extensive radio protocols. The energy storage unit is preferably disposed on a printed circuit board on which at least one electronic component of the radio transmission module is mounted.
It is further preferred for the method that, in addition to the mono-stable or bi-stable configuration of the energy converter, the radio transmission module is designed for bidirectional communication with a radio receiver module assigned thereto, wherein the rotational step also contains further sub-steps, following the transmission sub-step, sequentially generating a new radio transmission telegram upon receiving a radio confirmation telegram from the radio receiver module and transmitting the new radio transmission telegram, wherein a sub-step for a renewed generation of an electrical energy by means of the energy converter precedes the sub-step for generating a new radio transmission telegram, or is inserted between the sub-step for generating a new radio transmission telegram and the sub-step for transmitting a new radio transmission telegram. As a result, improved system reliability can be ensured.
The preferred embodiments of the actuation handle, the device, and the method described above are suited in particular for window or door handle monitoring systems, by means of which a change or a manipulation of the actuation handle can be monitored. The preferred embodiments can be used, for example, in conjunction with a signaling system for monitoring and closing a window or door. The signaling system can comprise, in addition to a preferred embodiment of an actuation handle, a solar energy converter for converting light energy into electrical energy, having an energy storage unit, in particular a rechargeable battery for storing the generated electrical energy. The solar energy converter can be disposed directly in the window pane, for example. Furthermore, the signaling system comprises a vibration sensor and/or a sound converter mechanism, such as a microphone, for monitoring the window or the door in order to signal an unauthorized opening or damaging of the window or door. For this, the signaling system further comprises a signal processing device having a radio transmission module, which processes the signals received from the vibration sensor or the sound converter mechanism, and can transmit a radio transmission telegram containing data regarding an unauthorized opening or damaging by means of the radio transmission module. The signal processing device is coupled to a solar energy converter, such that it can be supplied with electrical energy. The signal processing device is furthermore preferably designed to function as a repeater for a radio transmission telegram transmitted from the actuation handle according to a preferred embodiment.
Further features and advantages of the disclosure can be derived from the following description of preferred exemplary embodiments of the disclosure, based on the figures and drawings, which illustrate details essential to the disclosure, and from the claims. The individual features can each be implemented in and of themselves, or in numerous arbitrary combinations, in a preferred embodiment of the disclosure.
Various exemplary embodiments and details of the disclosure shall be described in greater detail based on the figures described below. Therein:
In the following description of preferred exemplary embodiments of the present disclosure, the same or similar reference symbols shall be used for identical elements, or elements having a similar function, depicted in the various figures, wherein there shall be no detailed repetition of the description of these elements.
The actuation handle 1 comprises a rosette 8, through which the actuation bolt 2 is inserted, and in relation to which the handle piece 6 can rotate. A rosette for an actuation handle is normally provided for attaching the actuation handle to a window frame or a door. In the illustrated preferred exemplary embodiment, the rosette 8 is connected to a device 10 on the side facing away from the handle piece 6, through which the actuation bolt 2 is likewise inserted.
The housing 12 has a pan-like section 13 inside the interior space 22 of the pan, between the two attachment holes 20, which is formed by further internal housing walls 26 extending upward from the pan base 24. The pan-like section 13 comprises a first receiving section 14 for receiving an energy converter 30 and an aperture 16 bordering on the first receiving section 14, having a second receiving section 18 for rotatably receiving a section of the actuation bolt 2. An aperture hole 19, bordering on the second receiving section 18, is formed in the pan-like section 13 in the pan base 24, through which the free end of the actuation bolt 2 can be inserted.
The inner housing walls 26 are enclosed by a delimiting, circumferential outer housing wall 28, which is connected to the pan base 24 at the edges. The inner housing walls 26 form a support or bearing for a carrier element 50 at their free, front surface ends 27. The free, front surface end 27 is closer to the pan base 24 than the free front surface end 29 of the outer housing wall 28 aligned therewith. As a result, the carrier element 50 can be accommodated in the pan interior 24.
The carrier element 50 has an outer contour corresponding to the inner contour of the outer housing wall 28, by means of which the carrier element 50 covers the pan interior 24 when it is received in the housing 12. In conjunction with the outer housing wall 28, the pan interior 24 can be protected against external effects.
The carrier element 50 has through-holes 52 corresponding to the attachment holes 20 and the positions assigned to the aperture 18, through which the actuation bolt 2 as well as the attachment means for the rosette 8 can be inserted. The carrier element 50 supports a radio transmission antenna 54, which can be coupled to a radio transmission module for wireless transmission of a radio signal. For this, the carrier element 50 is designed as a printed circuit board. The arrangement of the radio transmission antenna 54 on the carrier element 50 enables a reliable emission of the radio signal, as well as a reliable reception of a corresponding radio signal when the radio transmission module is configured for bidirectional communication. The surface area made available by the carrier element 50 can therefore be exploited in an optimal manner for the radio transmission antenna 54.
The carrier element 50 further comprises an encoding element 60 that can be assigned to a position detection device. The encoding element 60 comprises four circle segment-like sliding contact surfaces 62 disposed in a circle, which are disposed on a side of the carrier element 50 facing away from the housing 12 in the proximity of the through-hole 52 provided for the actuation bolt 2. The four sliding contacts 62 are electrically insulated in relation to one another. The encoding element 60 furthermore has a collective sliding contact 64 disposed concentrically to the four sliding contact surfaces 62, which can be electrically coupled to the energy converter 30 via the carrier element 50. Each of the four sliding contact surfaces 62 forms an electrically conductive contact bridge with the collective sliding contact surface 64. A contact element 70 is provided for an electrical connection of the respective contact bridge, which is non-rotatably disposed on the actuation bolt 2 between the carrier element 50 and the rosette 8. The contact element 70 can likewise be assigned to the position detection device. The contact element 70 is formed by an electrically conductive spring-like contact disk, which covers the four sliding contact surfaces 62 as well as the collective sliding contact surface 64. The contact element 70 has, on the side facing the carrier element 50, eight spring-like sliding contact fingers 74 for establishing an electrically conductive contact to the collective sliding contact surface 64, and two spring-like sliding contact fingers 72 for establishing an electrically conductive contact to one of the four sliding contact surfaces 62 respectively, depending on a rotational position of the actuation bolt 2, or the handle piece 6. As a result, a reliable electrically conductive contact between the encoding element 60 and the contact element 70 can be ensured.
Depending on a rotational position of the actuation handle 1, the two sliding contact fingers 72 establish an electrically conductive contact with one of the four sliding contact surfaces 62, while the eight sliding contact fingers 74 establish an electrically conductive contact to the collective sliding contact surface 64. As a result, an electrically conductive connection is produced between one of the four sliding contact surfaces 62 and the collective sliding contact surface 64, when current flows through it as the result of a generation of an electrical energy by the energy converter 62. By assigning the four sliding contact surfaces 62 to respective functional positions, or positions of the actuation handle 1, respectively, a position of the actuation handle 1 can be reliably detected, and transmitted by means of the radio transmission module. Further sliding contact surfaces and corresponding sliding contact fingers that can be assigned thereto for a reliable detection of the position of the actuation handle 1 are conceivable.

The switch element 32 is designed as a leaf spring mechanism. The leaf spring mechanism is configured to first store the mechanical energy transmitted during actuation from the actuation bolt 2 via the outer edge 4, or the mechanical energy transmitted from the actuation adapter element 40 shown in
The coil assembly 34 comprises a U-shaped soft magnetic coil core, the respective legs of which are encompassed in an induction coil. The magnet assembly 36 is disposed such that it can be moved linearly on the free ends of the coil core legs, and comprises an E-shaped magnetizable pole shoe assembly, wherein the outer legs of the E-shaped pole shoe assembly are magnetically connected to a magnetic pole of a permanent magnet bordered by the E-shaped pole shoe assembly, and the middle leg of the E-shaped pole shoe assembly is magnetically connected to the other magnetic pole of the permanent magnet. The free leg ends of the E-shaped pole shoe assembly are magnetically coupled to the free leg ends of the coil assembly 34 via a magnetizable sliding plate disposed between the pole shoe assembly and the coil assembly 34. In a first movement end position of the magnet assembly 36, a free end of one of the outer legs of the pole shoe assembly lies opposite a free leg end of the coil assembly 34, and the free end of the middle leg of the pole shoe assembly lies opposite the other free leg end of the coil assembly 34, in each case with the collective sliding plate placed therebetween. In this first movement end position, a magnetic flux having a first direction is generated in the coil assembly 34. In the second movement end position of the magnet assembly 36, the free end of the other outer leg of the pole shoe assembly lies opposite a free leg end of the coil assembly 34, and the free end of the middle leg of the pole shoe assembly lies opposite the other free leg end of the coil assembly 34, in each case with the collective sliding plate placed therebetween. In this second movement end position, a magnetic flux having a second direction is generated in the coil assembly 34, which direction is opposite the first direction. The magnetic flux direction reversal is caused by a movement of the magnet assembly 36 from the first movement end position into the second movement end position, or vice versa, by means of which a corresponding induction voltage is induced in the respective induction coils.
The energy converter 30 has electrical contacts 37 on the side of the coil assembly 34 facing away from the magnet assembly 36, which are electrically connected to another printed circuit board 38 by means of plug-in contacts. The other printed circuit board 38 is electrically coupled to the carrier element 50. In this preferred exemplary embodiment, the other printed circuit board 38 is configured to commutate the individual induction coils of the coil assembly 34. In accordance with another preferred exemplary embodiment, the other printed circuit board 38 carries some or all of the components of the radio electronics and/or the at least one logic module.
The actuation bolt 2 is shown in a movement state between two functional positions of the actuation handle 1, wherein the actuation bolt 2 is moved by means of pivoting the handle piece 6 along a rotational direction B in the counterclockwise direction when looking toward the end of the plane of the sheet. The actuation bolt 2 comes in contact with the switch element with one of its outer edges 4. If the actuation bolt 2 is rotated further along the rotational direction B, a pressure force transmitted by the outer edge 4 acts on the switch element 32, which is pushed further toward the coil assembly 34 as a result of its elastic spring design, without the magnet assembly 36 moving. The outer edge 4 approaches the actuation bolt 2 during the rotational movement in a continuous manner, until it reaches a point closest to the coil assembly 34, which the outer edge 4 moves away from when the actuation bolt 2 is rotated further along the rotational direction B of the coil assembly 34 shown herein. The magnet assembly 36 is still retained in its first movement end position due to the magnetic self-retaining forces acting between the magnet assembly 36 and the coil assembly 34. The mechanical force in the form of a pressure force acting on the switch element 32 is first stored during the rotational movement of the actuation bolt 2. As soon as the amount of the stored energy exceeds the amount of magnetic self-retaining force as a result of further rotating the actuation bolt 2, or the outer edge 4 approaching the coil assembly 34, the magnet assembly 36 is moved abruptly, along a movement direction C, from the illustrated first movement end position into the second movement end position. The abrupt movement of the magnet assembly 36 preferably occurs before, or alternatively, preferably at the latest, when the outer edge 4 reaches the point that is spatially closest to the coil assembly 34. The actuation bolt 2 is in an actuation end position thereby. This movement causes a magnetic flux direction reversal in the coil assembly 34, by means of which a voltage in the induction coils is induced. The electric energy generated thereby is transmitted via the plug-in contacts 37. As soon as the actuation bolt 2 is rotated in the clockwise direction, opposite to the rotational direction B, a similar actuation of the switch element 32 occurs.
According to a preferred exemplary embodiment, the energy converter 30 is mono-stable, and in other words, is thus self-resetting. For this, the switch element 32 is preferably configured such that it is in a relaxed state when the magnet assembly 36 is in the first movement end position, and is in an elastic tensioned state when it is in the second movement end position. As soon as the amount of pressure force acting on the switch element 32 by the outer edge 4 as a result of further rotation of the actuation bolt 2 is lower than the amount of self-resetting spring force of the switch element 32, and at the same time, the amount of self-resetting force is greater than the amount of magnetic self-retaining force, the magnet assembly 36 is moved abruptly back from the second movement end position into the first movement end position, by means of which a renewed induction voltage is generated.
According to an alternative preferred exemplary embodiment, the energy converter 30 is bi-stable. For this, a reset spring device that resets the magnet assembly 36 is provided, which has an actuatable end, which can be brought into the rotational path of the outer edge 4 after actuation of the switch element 32, such that it can be actuated for switching, and after actuation, remains outside of the rotational path of the outer edge 4 until the switch element 32 is actuated again. The actuatable end of the reset spring device can be disposed upstream or downstream of the switch element 32 in the rotational direction of the actuation bolt 2, or the outer edge 4, such that it can be brought into the rotational path of the outer edge 4. Thus, depending on a use oriented configuration of the actuation handle 1, a double actuation can occur, in order to obtain a high energy gain, or a single actuation of the energy converter 30 can occur during a rotation of the actuation bolt 2, or while the actuation handle 1 is being brought into a functional position from another functional position.
According to another preferred exemplary embodiment of the method 1000, the energy converter 30 has a mono-stable or bi-stable design, wherein the rotating step 1100 furthermore exhibits sub-steps following the sub-step for transmission 1130 in the sequence, for the renewed generation 1140 of an electrical energy by means of the energy converter 30, and the repeated transmission 1150 of the generated radio transmission telegram. As a result, a transmission reliability can be increased.
According to another alternative preferred exemplary embodiment of the method 1000, the rotating step 1100 furthermore contains sub-steps following the sub-step for transmitting 1130 in the sequence, for generating a new radio transmission telegram 1160 containing data regarding the action of the actuation handle 1 and the transmission 1170 of the new radio transmission telegram, wherein a sub-step for the renewed generation 1140; 1165 of an electrical energy by means of the energy converter can be disposed upstream of the sub-step for the generation 1160 of a new radio transmission telegram, or it can be provided between the sub-step for the generation 1160 of a new radio transmission telegram and the sub-step for the transmission 1170 of the new radio transmission telegram. This can be selected, as needed, depending on the energy consumption of the sub-steps for generating the radio transmission telegram and the new radio transmission telegram, or other aspects relating to energy.
According to another preferred exemplary embodiment of the method 1000, the actuation handle has an electrical position detection device for electrically detecting a position of the actuation handle coupled to the radio transmission module. The actuation handle that has the position detection device can be, for example, one of the actuation handles 1 described above. With the method according to this preferred exemplary embodiment, the rotating step 110 comprises a sub-step for closing 1105; 1115 a contact bridge assigned to a position of the actuation handle 1, disposed upstream of the sub-step for generating 1120 a radio transmission telegram, in order to detect the position of the actuation handle 1, wherein the data in the radio transmission telegram contains data regarding the position of the actuation handle 1. In this case, the closing step 1105; 1115 can already be disposed upstream of the sub-step for generating 1120 a radio transmission telegram, or it can be disposed between the sub-step for generating 1110 electrical energy, and the sub-step for generating 1120 a radio transmission telegram. Thus, in addition to data regarding the actuation of the actuation handle 1, data regarding the detected position of the actuation handle 1 can simultaneously be transmitted in a wireless manner. A status monitoring of the actuation handle can be simplified by this means.
According to another preferred exemplary embodiment of the method 1000, the actuation handle comprises, in addition to a mono-stable or bi-stable energy converter, an electrical energy storage unit, e.g. a capacitor, wherein the rotating step 1100 exhibits a sub-step for the storage 1124 of an excess electrical energy provided between the sub-step for generating 1120 a radio transmission telegram and the sub-step for transmitting 1130 the radio transmission telegram, and a sub-step following this sub-step for the renewed generation 1126 of an electrical energy by means of the energy converter. This preferred method contains the advantage of a higher energy availability, by means of which radio protocols requiring more energy can be reliably transmitted.
According to another preferred exemplary embodiment of the method 1000, the actuation handle has a radio transmission module for bi-directional communication with a radio receiver module.
Other sub-steps can certainly be provided between the individual sub-steps of the preferred method 1000 described above. By way of example, according to another preferred exemplary embodiment of the method for an actuation handle having a position detection device, a sub-step for querying a position of the actuation handle by means of an electronic logic module can be disposed downstream of the sub-step for generating an electrical energy, disposed upstream of sub-steps forming a (renewed) generating of a (new) radio transmission telegram. Alternatively, individual sub-step can follow one another directly, in other words, without further sub-steps. Furthermore, in the sub-step for transmitting a radio transmission telegram, a single or a repeated transmission of the radio transmission telegram can occur. This applies equally to the sub-steps for the renewed transmission of the radio transmission telegram or the transmission of a new radio transmission telegram. As a result, a transmission reliability can be further improved.
