Description

[0001] The invention relates to an actuating device for movable wings of opening closures of buildings with the features in the preamble of the main claim.

[0002] Such an actuating device is known from DE 20 20 2010 008 488 U1. It is designed as a chain drive, comprising a drive unit and a push chain in a first housing, as well as an attachment module with a second housing or body containing external control electronics. The attachment module is plugged onto the first housing of the drive unit from the outside, extending it, with the outer contours of the two housings being aligned. A medial and a mechanical connection can be established between the drive unit and the attachment module, the medial connection comprising interacting interfaces in the form of electrical contact strips on a projecting base on the end face of the first housing of the drive unit and on the bottom of a recessed, end-face, bushing-shaped receptacle on the housing of the attachment module.A manually operated button protrudes laterally from the housing of the add-on module.

[0003] DE 20 2004 020 163 U1 discloses an actuating device with two drive units, each designed as a chain drive and each with its own housing. Solid electrical contact pins can be inserted into the end faces of the housings to allow the power supply to be looped through.

[0004] DE 10 2013 204 796 A1 relates to a pre-assembled component of a building locking device. An electromechanical drive device for a window sash and a drive device for a roller blind are each connected via cables to the solar energy storage unit, to control electronics and a sensor module, which are each arranged separately and at a distance from the drive devices.

[0005] DE 10 2008 022 714 A1 concerns the activation of functions in a door drive, whereby function-specific electronic cards are inserted into an openly accessible slot on a basic module of the door drive as required.

[0006] DE 10 2013 207 455 A1 discloses pivotable doors or windows with drive devices and each with a control unit housed separately from the drive unit in the window or door frame or in a flush-mounted box, which includes a control part and an electronic switching power supply unit together with a common processor.

[0007] Actuating devices are known in practice, for example, as wing drives, in particular chain drives or spindle drives, or as locking devices. The known actuating devices have a drive unit with an integrated control system and a movable, driven actuator, which is designed, for example, as a push chain, spindle, locking element, or the like.

[0008] The object of the present invention is to demonstrate an improved actuating device with regard to the accommodation of an attachment module.

[0009] The invention solves this problem with the features in main claim 1.

[0010] The claimed actuating device has an add-on module that can be connected to the drive unit from the outside. This add-on module is designed as a plug and is recessed in a socket-shaped receptacle within the drive unit housing. The add-on module comprises a body with one or more additional functional elements for the drive unit. The add-on module, the body, the one or more functional elements, and the interfaces are all enclosed by the housing, with the recessed add-on module being accessible from the outside at its rear side, which is visible when plugged in.

[0011] The add-on module can be designed as a single plug or as a multiple plug, in particular a double plug.

[0012] The add-on module can be designed in various ways, and different add-on modules may be available. The differences between the add-on modules can lie in the number and configuration of one or more additional functional elements. The external dimensions of the various add-on modules can remain the same.

[0013] The add-on module, preferably fully recessed within the housing's internal receptacle, particularly a single connector, does not protrude from the housing or only minimally. It is completely surrounded by the housing and accessible from the rear.

[0014] The recessed module arrangement within the housing offers the advantage that the external dimensions of the actuator or its drive unit, particularly its length, are defined by the housing. This saves space and facilitates the standardization and deployment planning of the actuators or drive units. The external dimensions of the drive unit, or the installation dimensions, can remain the same even when using different add-on modules or when replacing a module. The housing size or installation dimensions may vary depending on the selected actuator and motor power.

[0015] In the multi-connector variant, the add-on module can protrude from the housing of one drive unit and be recessed into the housing of the other drive unit using this protruding portion. The housings of the different drive units can abut above the multi-connector, especially a double connector, or at least be very close together with only a small gap. This offers the same advantages mentioned above, particularly space savings and simplified standardization and deployment planning.

[0016] The variable modular design offers the advantage that the operating mechanism can be configured as desired by selecting one or more add-on modules. The configuration can also be changed again if needed. This provides a wide range of different operating mechanisms while simultaneously minimizing construction and storage costs.

[0017] The operating device can have a selectable range of functions. This range of functions can also be changed again. Furthermore, it can be ported when, for example, defective operating devices are replaced.

[0018] The drive unit can be designed as a standard unit with a uniform, limited basic range of functions, with the add-on module providing one or more additional functions to fulfill the selected range of functions of the actuating device.

[0019] The drive unit can be used as a standardized and unified drive unit for a wide variety of configurations and functionalities. It can, for example, include an electric drive motor, possibly with a downstream or integrated gearbox, and an actuator, such as a push chain. The actuating device can be connected to a power supply with alternating or direct current, in particular to an AC mains supply.

[0020] The drive unit can be present individually or in multiples. In a multiple configuration, the several drive units can be connected to each other by a cable or a multi-connector adapter.

[0021] Standardization allows the drive unit to be produced more cost-effectively in larger quantities and with fewer variants. The required configuration or selected functionality of the actuator is achieved through the additional function(s) of the chosen add-on module, complementing the basic function(s) of the drive unit. The housing size and installation dimensions can remain the same.

[0022] Conversely, an add-on module can also be used in conjunction with different drive units. These drive units can vary in size and performance, offering, for example, different opening and closing forces, and different extension lengths for push chains, spindles, or similar components. Drive units can also differ in their design, particularly their actuator or output element. A modular system can be created using different drive units and add-on modules. The same add-on module can be used, for example, for a chain push drive, a spindle drive, a locking mechanism, or similar applications. In this context, the individual designs of the drive units and add-on modules are also adapted and standardized accordingly.

[0023] An add-on module can be functionally variable. It can provide different additional functions, which vary in number and combination. Therefore, a modular system can include different types of add-on modules.

[0024] Several add-on modules can be mounted on a single drive unit. The housing can have multiple mounting points. Furthermore, it is possible to connect several add-on modules together and, if required, cascade or connect them in series.

[0025] The inserted module fills the recess and seals the housing opening tightly to the outside. For this to work, a mutual fit between the recess and the module, especially around the circumference, is advantageous. This also ensures a secure fit.

[0026] A detachable and lockable connection can be established between the drive unit and the attachment module. This is preferably a plug-in connection. The plug-in connection can have a single, preferably linear, plug-in axis. Alternatively, other connection types are possible, e.g., a screw connection, a bayonet connection, or the like. The connection can be protected against environmental influences, in particular by sealing. The connection allows for the removal and replacement of an attachment module as needed.

[0027] The connection between the drive unit and the mounting module comprises a mechanical connection and a media connection. The mechanical connection can be locked in place, preferably for safety reasons, and can only be released with a tool. The mounting module, inserted into the receptacle, is accessible from the rear for this purpose. The media connection allows media, such as electrical energy, in particular power currents and / or signals, to be transmitted from the mounting module to the drive unit and, if necessary, back again. In the case of a mounting module designed as a multi-connector, these media can be transmitted between the connected drive units.

[0028] The housing of the drive unit has one or more receptacles for an add-on module. A housing with a slim and elongated shape is particularly suitable, with a socket-like receptacle located, for example, on one or both end faces of the housing. The add-on module is designed as an adapted connector.

[0029] A double-sided arrangement of add-on modules with additional functional elements on the drive unit, which is equipped with multiple mounting points, enables a medial and, if necessary, mechanical connection between several drive units. A multi-connector design allows for both types of connection. With a single cable or line, only one medial connection is possible. If only one add-on module with additional functional elements is required, a blanking plug can be inserted into the other mounting point.

[0030] The media connection features interconnected interfaces on the drive unit mount and the add-on module. An add-on module can have only one such interface and, optionally, a power or cable connection on another side. Alternatively, an add-on module can have multiple interfaces on different sides, allowing several add-on modules to be connected together. Such a mutual and optional plug-in connection enables the creation of a module cascade and also a functional cascade. With multiple interconnected add-on modules, the media connection can be looped through.

[0031] The add-on module comprises a body with one or more functional elements arranged within and, if applicable, on the body. The functional elements can be present in any number, combination, or arrangement.

[0032] A functional element can be a control unit, which may also include its own intelligence, e.g., a control board with a processor, and possibly also a data storage device as a further functional element. A functional element can also be a safety switch for pinch protection, which may be assigned to or implemented within the control unit. The drive unit can have a reduced control unit, e.g., a motor controller, whereby the control units of the attachment module and the drive unit interact and together form the control system for the actuating device.

[0033] Functional elements can, on the other hand, be configured as a detection device, in particular a decoder of an electrical current signal, as a display, as a wired or wireless communication unit, as an energy storage device, or in other ways, in particular as a battery or as strain relief for a cable. These functional elements can be combined with one another in any way.

[0034] To supply power to the drive unit, an add-on module can include a functional element designed as an electrical converter, in particular as an electrical transformer or preferably as a controllable or adjustable electronic switching power supply. The electronic switching power supply can be coupled to the control unit, and in particular, a shared processor may be present. The shared processor is, for example, arranged on the control board and serves to control the switching power supply and the drive unit, in particular its drive motor. The electronic switching power supply can convert an unstable input voltage, in particular mains AC voltage, into a constant and stable DC voltage.

[0035] The actuator can include an external detection device, in particular one or more sensors. These can be connected to and communicate with the attachment module. This can be done, for example, via a wired connection or wirelessly.

[0036] The operating device can be operated in various ways, e.g., via a mobile control unit and / or a stationary control unit. The control unit can include a piezoelectric element, in particular a piezoelectric switch, which generates an electrical current when activated. This current can be used for wired or wireless signal transmission, possibly to a communication unit in an add-on module. Furthermore, it can be connected to a higher-level control system, e.g., a control system for automated natural ventilation of buildings, for smoke and heat exhaust ventilation (SHEV), etc.

[0037] One or more operating devices can be arranged on a building's opening mechanism or on its wing. For example, several operating devices that drive the wing movement, such as chain drives, spindle drives, or the like, can act on the wing together and synchronously.

[0038] Further advantages of the invention lie in increased ease of use and safety in the event of an accident for a window or a flap. A window can be upgraded or retrofitted to become a so-called mechatronic window. In particular, anti-pinch protection can be easily implemented. It can also be retrofitted as needed. A ventilation flap can be used with appropriate controls and sensors for automated natural ventilation. An opening mechanism, especially a window or a ventilation flap, can also have its own energy supply, e.g., through photovoltaics with attached solar collectors or integrated luminescent solar concentrators, and can be energy self-sufficient. For this purpose, an attached energy storage unit in an add-on module is advantageous.

[0039] The actuator(s) can be powered via a line voltage. All control functions of an actuator, whether individually or in groups, can be used. A full set of diagnostic functions is also available. No additional space is required for installation or terminals.

[0040] Further advantageous embodiments of the invention are specified in the dependent claims.

[0041] The invention is illustrated in the drawings in an exemplary and schematic manner. Specifically, the drawings show: Fig. 1: an opening closure for a structure with multiple actuating devices, each consisting of a drive unit and at least one attachment module, Fig. 2 and Fig. 3: different designs of an operating device according to Fig. 1, Fig. 4 and Fig. 5: Perspective views of parts of the operating mechanism, Fig. 6: a schematic diagram for the training and wiring of an add-on module, Fig. 7: a variation of Fig. 1 with a different power supply and a different control unit, Fig. 8: an actuating device according to Fig. 7, Fig. 9: a variant of the actuating device with an electronic switching power supply, Fig. 10: a variant of the actuating device with a different actuator. Fig. 11 and Fig. 12: another variant of the operating device with a multi-plug.

[0042] The invention relates to an actuating device (1) for an opening closure (3) of a structure, e.g., a window or a ventilation flap. The actuating device (1) comprises a drive unit (2) and at least one attachment module (5). The invention also relates to the drive unit (2) itself and an attachment module (5) itself.

[0043] The actuating device (1) can be present on a single or multiple opening closure (3). There can be different actuating devices (1) with different designs and functions for the opening closure (3). In the case of multiple actuating devices (1), these can be identical or different from one another.

[0044] In Fig. 1 and Fig. Figure 7 shows, for example, two actuating devices (1). The actuating device (1) located on the top of the opening lock (3) is, for example, designed as a chain drive for a tilt window. The actuating device (1) located on the left side is, for example, a locking mechanism that locks and secures the opening lock (3) in the closed position. Alternatively or additionally, other arrangements on the opening lock (3) as well as other functional designs of actuating devices (1) are possible, for example, in the form of spindle drives, door drives, lifting devices, or the like. Fig. 1 to 4, as well as Fig. 8 and Fig. Figure 9 each shows an example of a chain drive. Fig. Figure 10 shows a spindle drive.

[0045] The opening mechanism (3) can be designed in any way. For example, it has a preferably stationary frame and a wing (4) movably mounted thereon with any kinematics. Fig. 1 and Fig. Figure 7 shows, for example, a tilt window where the window sash (4) rotates around lower bearings and a horizontal axis. Alternatively, the sash (4) can rotate around another axis, e.g., an upright one, and / or perform a linear movement, e.g., a lateral sliding movement or a lifting movement.

[0046] The actuating device (1) comprises at least one drive unit (2, 2') with a housing (16, 16') and with a movable, driven actuator (14). The actuator (14) preferably engages the sash (4), e.g. via a fitting. In the case of the Fig. 1 to 4, as well as Fig. 8, Fig. 9 and Fig. In the chain-driven actuator shown in Figure 11, the actuator (14) is a push chain that exits laterally from the housing (16, 16'). Alternatively, a spindle or rack drive with, for example, an axial exit of a rod- or spindle-shaped actuator (14) at the end face is possible according to Figure 11. Fig. 10 possible. In the locking mechanism shown, the actuator (14) is a locking element, e.g. a latch, a locking bolt or the like. The actuators (14) can have different kinematics. They can, for example, be extended and retracted linearly and / or rotationally.

[0047] Fig. 2 and Fig. Figure 3 schematically illustrates the design of a drive unit (2, 2'). The housing (16, 16') preferably has a slim and elongated shape. Preferably, the shape is straight. Alternatively, it can be curved. The housing (16, 16') can be attached to the opening closure (3) at any suitable location on the outside or be partially or completely recessed into a frame or wing component. The housing (16, 16'), which is e.g., tubular, can be made of metal, in particular light metal, or another suitable material, e.g., plastic.

[0048] The drive unit (2) comprises a controllable drive (15), which is designed, for example, as a low-voltage DC motor with 24 V or in another suitable manner. The drive (15) may also include a downstream separate or integrated gearbox. Furthermore, an output element for the actuator (14), such as a sprocket, a spindle, a spindle nut, or the like, may be provided. A guide or mounting, such as a chain track, may be provided for the actuator (14). The drive (15) may include a control unit. This may have a reduced design and functionality. It may, for example, consist of a motor control board. The drive (15) is housed with the aforementioned components inside the casing (16, 16').

[0049] The actuating device (1) has an attachment module (5) that can be connected to the drive unit (2, 2') from the outside. The attachment module (5) remains accessible from the outside when installed or attached. It has one or more additional functional elements (23-30) for the drive unit (2, 2'). The functional elements (23-30) can be present in any number, combination, and configuration. There can be different attachment modules (5) with varying arrangements and functional scopes of the functional elements (23-30).

[0050] The actuating device (1) has a selectable range of functions. An actuating device (1), which, for example, moves or opens and closes a wing (4), can be arranged singly or in multiples on the opening lock (3). In the case of multiple arrangements, the different drives can be coordinated with each other in their drive function, in particular their speed, and especially synchronized.

[0051] A corresponding joint control of the actuators (1) can be achieved by an external controller and by linking the actuators (1) via cables, in particular bus lines. Alternatively, one of the actuators (1) can assume the control tasks and a master function, with one or more other actuators (1) acting as slaves. In another variant, it is possible for the actuators (1) to coordinate and synchronize with each other, without a higher-level control function.

[0052] The one or more actuating devices (1) can be connected individually, jointly, or in groups to a power supply (13) by means of a line (12), in particular a cable, an inductive transmission, or the like. The power supply (13) can be located externally, e.g., on a building or on the opening mechanism (3). The opening mechanism (3) can alternatively or additionally have its own power supply (13'), e.g., solar cells with an energy storage device, in particular a battery. The power supply (13, 13') can, for example, supply direct current or alternating current. For direct current, the line (12) can, for example, have 5 poles, divided into 2x power contacts, 2x data contacts, and 1x potential-free signaling contact. For alternating current, for example, 6 poles can be provided for 2x power, 2x data, and 2x signaling.

[0053] The one or more actuating devices (1) can be operated individually or jointly by means of an operating unit (10, 10'). This unit can be stationary and / or mobile and can be present singly or in multiples. The connection and, if applicable, the encrypted communication between the actuating device (1) and the operating unit (10) can be wireless or wired.

[0054] In Fig. Figure 1 schematically depicts a non-stationary or mobile and wireless control unit (10) or remote control. This could be, for example, a smartphone that communicates wirelessly with the operating device(s) (1) via radio or other means. During a connection or communication, control data, status data, or other messages can be exchanged. An app may be used for communication.

[0055] Fig. Figure 7 shows a variant with a stationary control unit (10'), which is designed, for example, as a push button on a wall. The control unit (10') can be connected to the actuating device(s) (1) by means of a wired line (12') or cable and / or wirelessly, e.g., via radio. The line (12') can be energized and can, for example, be connected to the building's AC power supply. The line (12') can also, for example, be a potential-free signal line.

[0056] The control unit (10') can include a piezoelectric element (35) or the like, which, when the control unit (10') is mechanically actuated, in particular a piezoelectric switch, emits a pulsed current that is used to transmit the control signal. For example, the signal line (12') can be energized as needed via this element. Fig. Figure 7 also shows a variant of a communication module (36), in particular a radio module, connected to the piezo element (35) for preferably wireless signal transmission to the actuating device(s) (1).

[0057] The one or more operating devices (1) can alternatively or additionally be connected to and controlled by a higher-level building control system, a fire alarm system, an alarm system, an automated natural ventilation system, a smoke and heat exhaust ventilation system (SHEVS), or the like. The connection can be made, for example, via line (12).

[0058] The aforementioned selectable range of functions of the one or more actuating devices (1) can, for example, consist of pre-programmed movement and drive functions for the sash (4). In addition to end positions in the open and closed positions, predefined or selectable intermediate positions can also be reached. Furthermore, manual operation by sight is possible.

[0059] Furthermore, the one or more operating devices (1) can be connected to an external detection device (11). This is in Fig. 1 and Fig. 7 schematically indicated. It can, for example, have one or more external sensors (33, 34) in or on the building. These can be, for example, wind sensors, solar radiation sensors, rain sensors, smoke detectors, fire detectors, temperature sensors, humidity sensors, sound sensors, locking sensors, or the like. They can, for example, detect special environmental conditions to which the one or more operating devices (1) react appropriately, for example, by opening or closing the sash (4).

[0060] The selectable range of functions may also include mutual coordination of different types of actuating devices (1). The in Fig. 1 and Fig. The locking mechanism shown in Figure 7 must, for example, upon receiving an opening command for the sash (4), first unlock the sash (4) and report this to a higher-level control system or another actuating device (1), which can then drive the sash movement. The sequence is reversed when closing, with the locking mechanism only engaging after the actuating device (1) has entered the closed position. Additional functions can be externally imposed, for example, via a higher-level building control system, a fire detection system, an alarm system, a smoke and heat exhaust ventilation system (SHEVS), automated natural ventilation, or similar systems.

[0061] The extended range of functions of one or more actuating devices (1) may also include monitoring, diagnosis and logging of their function and the aforementioned mutual coordination of several cooperating actuating devices (1).

[0062] In the illustrated and preferred embodiments, the drive unit (2, 2') is designed as a standard unit with a uniform, preferably limited, basic range of functions. The add-on module (5) then provides one or more additional functions to fulfill the selected overall range of functions. The add-on module (5) can be functionally variable. Different add-on modules (5) can have different additional functions. This will be discussed in more detail below.

[0063] A detachable and lockable connection can be established or exist between the drive unit (2, 2') and the attachment module (5). This can, for example, be a pluggable connection. The connection comprises, on the one hand, a mechanical connection (6) and, on the other hand, a medial connection (7), which are preferably closed and established when the drive unit (2) and the attachment module (5) are plugged together. In the illustrated embodiments, the plugging together is carried out with a linear and straight plugging motion. Alternatively, a rotary or a combined linear and rotary plugging motion can be used.

[0064] One or more attachment modules (5) can be arranged on the housing (16, 16') of the drive unit (2). For this purpose, the housing (16, 16') has one or more receptacles (18). In the preferably slim and elongated housing (16), a receptacle (18) can be arranged, for example, on an end face (17) of the housing (16). Fig. 1 and Fig. 2 demonstrate this training. In Fig. Figure 3 shows a variant with one receiver (18) at each of the front ends of the housing (16).

[0065] The receptacle (18) is designed as a hollow socket, with the attachment module (5) being designed as a plug. The receptacle (18) is arranged inside the housing (16). In the socket design shown, Fig. 1 to 5 and Fig. From 7 to 10, the attachment module (5) is fully recessed into the housing's internal receptacle (18). It does not protrude from the housing (16) or only protrudes slightly.

[0066] The add-on module (5) is available in the variants of Fig. 1 to 5 and Fig. 7 to 10 are designed as individual connectors (40). The individual connector (40) fills the housing-internal receptacle (18) in the aforementioned manner and preferably does not project axially outwards from its end opening. Fig. 11 and Fig. 12 is a variant of the adapter (5) in a design as a multiple plug (41), in particular a double plug, shown and described below.

[0067] The mechanical connection (6) has a code and a locking mechanism (8) that can preferably only be released with a tool. This is advantageous for fulfilling the safety criteria of the European Machinery Directive. The locking mechanism (8) can be designed as a positive locking mechanism, in particular as a spring-loaded snap or detent connection. This is advantageous in Fig. 2 and Fig. 3 schematically indicated as well as Fig. 4 and Fig. 5 is shown in more detail. It can only be used with one in Fig. 4 and Fig. The release mechanism (31) shown in Figure 5, e.g., a release window, is released using a tool attached there, e.g., a special key or the like. The correct installation and relative position between the receptacle (18) and the mounting module (5) can be ensured by the coding of the mechanical connection (6). The coding can consist, for example, of complementary external shapes, in particular ribs and grooves.

[0068] The medial connection (7) has interacting interfaces (19, 21) on the drive unit (2), in particular on its mounting (18), and on an attachment module (5). These can be, for example, electrical connector strips, terminals, or the like. The mechanical and the medial connection (6, 7) can be automatically and forcibly closed when the mounting (18) and the attachment module (5) are plugged together.

[0069] An add-on module (5), in particular a single connector (40), can have several interfaces (21, 22) on different sides. Several add-on modules (5) can be connected to each other via these interfaces. They can be configured in particular according to Fig. The three modules are arranged one behind the other in the axial direction and plugged together. A suitable mechanical connection meeting the aforementioned criteria can also be established. With several interconnected add-on modules (5), the medial connection (7) can be looped through.

[0070] The according to Fig. Three interconnected add-on modules (5), in particular single connectors (40), can form a module cascade or a function cascade. In the case of the Fig. In the arrangement shown in Figure 3, the second attachment module (5), in particular the single connector (40), can be arranged wholly or partially outside the housing (16). The axial length of the attachment modules (5), in particular the single connector (40), can correspond to the axial length of the receptacle (18).

[0071] In an alternative configuration not shown, the add-on modules (5), in particular individual connectors (40), can have a shorter axial length. This can be shorter than the axial length of the receptacle (18). This allows two or more connected add-on modules (5), in particular individual connectors (40), to be accommodated together within the receptacle (18). With suitable length adjustment, they can be arranged to be completely recessed in the receptacle (18).

[0072] According to Fig. 2 to 5 and Fig. A module (5), in particular a single connector (40), has a body (20) with one or more functional elements (23-30) arranged in or on the body (20), as shown in figures 8 to 10. The body (20) can have any suitable shape, for example, the cuboid shape shown. Alternatively, a cylindrical shape or another shape is possible. A cable entry (32) for the cable (12) can be arranged on the body (20) at a suitable location, e.g., on the rear. The body (20) can be made of any suitable material, e.g., plastic. The body material can differ from the material of the housing (16).

[0073] There are various possibilities for the design, function and arrangement of functional elements (23-30) and the associated additional functions. Fig. Figure 6 shows a schematic diagram of an extension module (5).

[0074] A functional element (23) of an attachment module (5) can, for example, be designed as a control unit. This can have its own intelligence, for example a control board (38) with a processor (37) according to Fig. 9. Such a control unit can, for example, contain its own programs. In one version, it can assume the aforementioned master function or ensure other mutual coordination. In another add-on module (5), the control unit can be designed or programmed for a slave function. Accordingly, there can be master and slave modules.

[0075] Another functional element (24) of an attachment module (5) can be configured as a data storage device. This can be configured according to Fig. 6 and Fig. 8. It may be connected to or assigned to the aforementioned control unit (23). It can store programs, operating data, logs, and the like.

[0076] A functional element (23') of an add-on module (5) can, for example, be designed as a safety switch and provide anti-pinch protection with an emergency closing option. It can be combined with the control unit (23).

[0077] For this purpose, the control unit can, for example, detect and monitor the motor current of the drive (15) with a current sensor (39), e.g. on the circuit board (38). Fig. Figure 8 shows this arrangement. The motor current can be related to a load acting on the wing (4). Current and load sensing allows for the detection of force increases acting on the wing (4), which can occur, for example, when reaching an end position or due to external influences such as wind pressure or obstacles. If, for example, a predefined load limit is reached, the control unit (23) can switch off and / or reverse the drive (15). The drive (15) can have a power reserve to ensure that the existing wing load can always be reliably closed with this power reserve.

[0078] With anti-pinch protection, the control unit can initiate a measurement run of the sash (4) either automatically or via an external signal, e.g., a reset button on the housing (20). The resulting force profile is detected via the motor current or other means and stored as a target curve. This can be done for opening and / or closing movements. During normal operation, the forces or motor currents are also recorded and compared with the target curve. If, during closing, an obstacle, e.g., a trapped body part, is detected by an unexpected increase in force, a suitable protective measure, e.g., a stop and / or a reversal of the drive (15), can be initiated. The aforementioned force profiles are recorded and stored as a function of the path of the sash (4) or the drive (15), which is also measured.

[0079] In another implementation for pinch protection, a constant threshold value can be added to the actual curve of the detected force or motor current. This threshold value corresponds to a force of a suitable magnitude, e.g., approximately 50 N, representing the pinch protection. An impending pinch and the associated detected increase in force lead, via the added threshold value, to a rapid reaching of the load limit and the initiation of the aforementioned protective measure.

[0080] Another functional element (25) of an add-on module (5) can be configured as a detection device. This can be, for example, a decoder of an electrical current signal that detects the polarity and direction of the supplied control current. By selectively polarizing an supplied direct current, for example, an externally applied control signal for opening or closing the wing (4) can be detected. The detection device (25) can also be connected to or associated with the aforementioned control unit (23).

[0081] An electrical control signal can also be transmitted together with a power current, in particular an alternating current. It can be modulated onto a house supply voltage, e.g., a so-called power network, or a mains voltage. The detection device (25) can also detect this control signal. To increase cybersecurity, which is particularly critical when connected to the public power grid, the control unit (23) can incorporate security technology, e.g., a firewall, an encryption device, or the like.

[0082] Another functional element (26) of an add-on module (5) can be configured as a display. This can be, for example, an optical, haptic, and / or acoustic display. An optical display is, for example, according to Fig. 4 and Fig. 5 are arranged on the rear side of the body (20) visible from the outside when plugged in. The display can signal acknowledgments, errors, operating states, alarms, or the like.

[0083] Another functional element (27) of an add-on module (5) can be configured as a wired or wireless communication unit. A wireless communication unit can, for example, be a radio unit. Via such a unit, in Fig. 6, Fig. 9 and Fig. The communication unit (27) shown in Figure 10 enables the add-on module (5), and in particular its control unit, to communicate with an external operating unit (10, 10'), especially a communication module (36), or the detection device (11), or with an external control or signaling unit connected via a cable (12, 12'). This allows, for example, a bus connection via cable (12) for a building management system. A bus can be configured in various ways, such as a CAN, USB, KNX, or LON bus. Wireless communication can be based on radio frequency, for example, via Bluetooth, Wi-Fi, Z-Wave, or other methods.

[0084] Another functional element (28) of an add-on module (5) can be configured as a converter. This can be, for example, an electrical AC / DC converter or DC / DC converter. An electrical converter can, for example, include a rectifier, which is used when connected to an external AC power supply (13). A converter can also include an electrical transformer, a chopper, or the like. The drive (15) can be controlled via pulse width modulation or pulse frequency modulation. This can be achieved using the media connection (7).

[0085] In a chain of several actuating devices (1), for example the first actuating device (1) can have an add-on module (5) with cable connection to a building network with 220 V and with a converter (28) and can supply the further actuating device(s) (1) via line (12) with DC voltage of e.g. 12 or 24 V.

[0086] In a modification of the aforementioned current or voltage converter (28), a functional element (28') can be designed as an electronic switching power supply (28') according to Fig. 6, Fig. 9 and Fig. 10. It can be connected on the one hand to an AC power supply (13) via a multi-core power cable (12) and on the other hand to the drive (15) and, if applicable, other consumers via the media connection (7). The controllable and, if applicable, adjustable electronic switching power supply (28') and the control unit (9), in particular the control unit (23), can have a common processor (37), possibly on a common circuit board (38). Alternatively, they can have separate processors.

[0087] Another functional element (29) of an add-on module (5) can be designed as an energy storage device. This can be, for example, an electric battery. This can provide emergency power in the event of a failure of an external power supply (13), in particular a private or public power grid, in order to open and close a wing (4) as needed in case of danger. It is opened, for example, for smoke extraction.

[0088] The energy storage device (29), in particular a rechargeable electric accumulator, can also be operated in conjunction with another electrical energy supply (13'), e.g. a solar cell array. Fig. 7 and Fig. Figure 8 shows an example of such an arrangement, wherein the electrical power supply (13') in the form of a solar cell is integrated, for example, into a flap or a window (3), in particular into its pane. Alternatively, the electrical power supply (13') can be arranged elsewhere, in particular outside the opening mechanism (3).

[0089] Another functional element (30) of an attachment module (5) can be arranged according to Fig. 4 is designed as a strain relief for a cable (12). At least one of the add-on modules (5) has a power connection with such a connection option for an external cable (12) and a cable inlet (32).

[0090] Further functions can be realized with the range of functions achievable by the drive unit (2) and one or more appropriately suitable attachment modules (5).

[0091] This applies, for example, to zero-voltage-proof operational data acquisition. This data can be read via a third conductor of an electrical cable. Furthermore, the control unit and, if applicable, the data storage device enable autonomous control of one or more operating devices (1). This can also be configured via a third conductor of a power cable (12). Control functions can include, for example, a daily / weekly program, with a one-day power reserve achievable without mains voltage. Control can also be dependent on temperature, brightness, and / or volume. Furthermore, voice control can be achieved through spoken commands or, in a simplified form, via clapping signals. Additionally, an add-on module (5) can automatically learn the settings when it is inserted into a receptacle (18).

[0092] Another function is a chain connection of several, e.g., synchronously operated, actuating devices (1) that together move a large and heavy wing (4). A wired or wireless connection between the actuating devices (1) can be established via add-on modules (5). Electrical energy and signals, e.g., control and / or signaling signals, can also be transmitted and, if necessary, looped through. A wired connection, preferably cabled, can exist between the several, e.g., end-mounted, receivers (18) or add-on modules (5) on an actuating device (1).

[0093] A module and / or function cascade can be formed by connecting two or more add-on modules (5), in particular single connectors (40), as described above. By connecting the add-on modules (5) in series, their functions can also be connected in series or added together. This makes it possible to achieve the desired range of functions by combining and connecting, in particular by plugging together, several add-on modules (5). This also allows for the subdivision of a modular add-on module system.

[0094] With appropriate adjustments to their shape and size, the two or more connected attachment modules (5) can be arranged together and recessed in the receptacle (18) of a housing (16). They may not protrude from the front opening of the receptacle (18), or only to a negligible extent. Alternatively, they can be arranged according to... Fig. 3 be trained.

[0095] Fig. 11 and Fig. Figure 12 shows a variant of an attachment module (5) and the actuating device (1). The attachment module (5) is designed as a multi-pin connector (41), in particular as a double connector. The wing (4) is actuated by two or more drive units (2, 2'). These can be synchronized in their drive movements. The drive units (2, 2') can be designed as described above. They can be identical.

[0096] The multi-connector (41) can be plugged into several, in particular two, housings (16, 16') of different drive units (2, 2'). The housings (16, 16') attached to this mounting module (5) on both sides abut each other via the multi-connector (41) according to Fig. 11. Alternatively, they can be adjacent with a small axial distance.

[0097] The multi-connector (41) can connect the drive units (2, 2') medially and, if necessary, also mechanically. Fig. Figure 12 shows an embodiment as a straight double connector. The multiple connector (41) is positively engaged and guided in the preferably identical receptacles (18) of the housings (16, 16'). It can form a medial and mechanical connector for the drive units (2, 2') and their housings (16, 16').

[0098] The add-on module (5) or the multi-connector (41) has an interface (21) on each of its end faces, which interacts with the interface (19) of the associated drive unit (2, 2'). The interfaces (21) are configured as described above, e.g., as electrical connector strips. In the illustrated embodiment of a straight double connector, the interfaces (21) are aligned on the end faces and point in opposite directions. The housings (16, 16') and drive units (2, 2') connected via these interfaces are arranged in a row in the same manner and are aligned with each other.

[0099] In another embodiment not shown, the multiple connector (41) can be configured as an angled double connector, wherein the connected drive units (2, 2') and housings (16, 16') are arranged at an angle and connected to one another. Furthermore, it is possible that the multiple connector (41) connects three or more drive units (2, 2') to one another in another configuration, e.g., diagonally.

[0100] At the in Fig. In the embodiment of the multi-connector (41) shown in Figure 12, the interfaces (21) are connected to each other in a suitable manner. This can be achieved by terminal strips on the back of the interfaces (21) and by cables routed inside the body (20) of the multi-connector (41). Alternatively, the terminal strips can be arranged together on a circuit board and mounted in the hollow body (20). This body can, for example, be designed as a plastic base.

[0101] The body (20) is adapted in its external geometry to the internal shape of the receptacles (18) and is guided in the attached receptacles (18) in a form-fitting manner. It may also have a centering feature or a stop for the housing end faces.

[0102] The body (20) can have at least one axial connecting web between the interfaces (21) and the body parts located there. This can also provide the mechanical connection of the attached housings (16, 16'). The body (20) can be open laterally according to Fig. 12. It can also be closed and form a housing in the form of a rectangular tube. Alternatively, the web can be multiple and / or form a profiled connecting arm, which, for example, has a U or X shape.

[0103] A mechanical locking device (8) of the aforementioned type may be present on the body (20), in particular on the aforementioned connecting bridge. It may be releasable from the outside.

[0104] In the illustrated embodiment, the multi-connector (41) has only the two or more interfaces (21) and their medial connection. It may also have one or more of the aforementioned additional functional elements (23-30) for the drive units (2, 2'). The halves or arms of the multi-connector (41) belonging to each drive unit (2, 2') may have identical or different additional functional elements (23-30).

[0105] At least one of the drive units (2, 2') has a housing (16, 16') with a receptacle (18) at both ends, in particular end faces, and with a medial connection looped between the two receptacles (18).
