Description

Modular drive device

The present invention relates to a modular drive device for electric motor adjustment of the fitting system of a window, a door or the like. The door can also be a French window. In principle, the modular drive device for windows or doors of all kinds, whether with window or opaque, be suitable, especially if the SE have a wing which is movably mounted on a frame and with means of a fitting system is adjustable, so that the modular Antriebsvorrich device used to an electromotive adjustment of the fitting system who can. For example, it may also be a flap.

A window or a door usually has a mounted in a wall frame and a by means of a fitting system on the frame be movably mounted wings. In this case, the wing from a closed position in which it rests in particular with a sash on the frame, are moved to an open position and back, with different geöff designated positions may be possible and by the fitting system various ne movement types can be made possible. The wing can by the loading impact system, for example, about a particular vertical axis of rotation drehöf fenbar to kippöffenbar tiltable or tiltable, in particular a horizontal tilting axis, or parallel but adjustable and optionally then be moved parallel bar. In addition, other types of movement as well as combinations (for example, rotatable and tiltable window) and overlays of said Be types of movement are possible.

The fitting system is typically adjustable, particularly between a locking condition in which the fitting system preferably locks the wing in its closed position so that the wing does not move to another Position can be moved, and a release state in which the wing between different positions can be moved. For this purpose, the loading impact system may have, for example, locking pins which are arranged on a driving rod provided on the folding frame between the sash frame and the frame and which depending on the sliding position of the drive rod engage in a respective closing part provided on the frame. The actuation of the drive rod is usually carried out via a window handle provided on the wing, the rotation of a gear of the loading impact system is derived to a displacement of the drive rod.

But there are also fitting systems conceivable by adjusting the wing not or not only can be locked or unlocked, but also between different positions can be moved. For example, by turning the window handle of a French window, its wings can be raised and / or parked in parallel so that they can subsequently be moved parallel by Fland. Thus, the fitting systems can also serve to facilitate operation of the fitting system, e.g. the turning of a window handle of the fitting system, in particular via a gear of the fitting system to derive a usually forcibly guided movement of the wing.

Regardless of whether the fitting system in addition to the movable mounting of the wing on the frame a locking and unlocking and / or a BEWE conditions of the wing, it may be advantageous to provide a particular elektromotori cal drive device to the window or door. By derar tiger drive devices, for example, windows can be operated, which are not or only poorly accessible for manual operation. In addition, they allow, for example, the user-independent ventilation of rooms and / or au tomatic unlocking windows or doors in case of fire, so that additional escape routes or access routes can be created from the outside for rescue workers. In general, drive devices can be used to provide windows, Assisted, automated and / or remotely lock, unlock, open and / or close doors and the like.

For this purpose, a respective drive device, e.g. be effective between the frame and the sash, about to open the wing by a thrust force and / or to close by a tensile force. For example, the drive device to be arranged on the window frame and have a pressure-resistant chain, which is extendable and retractable and connected to the wing. In this case, the force acting on the wing gravity can be used to move the wing by the retraction and extension of the chain relative to the frame and depending on how far the chain is extended to keep in a respective position.

Alternatively or additionally, a respective drive device but also interact directly with the adjustable fitting system, so that in that the fitting system is adjusted by the drive device, the window or the door can be opened, closed, locked and / or unlocked. For this purpose, the drive device is preferably arranged on the casement and coupled to the drive mechanism with the fitting system provided thereon in order to be able to adjust it, in particular by an electric motor.

Drive devices for the electromotive adjustment of the fitting system of a window, a door or the like are usually not provided on the window or the door from the outset or integrated into this, but are typically retrofitted to it. In this case, for the attachment of the drive device to the window or the door basically on the one hand, the possibility to put them from the outside on the frame or the wing, in particular on the sash, and on the other hand, the possibility of fully constantly covered within the frame or of the wing, in particular the sash, to install. The window or the door is usually not already specially prepared for the attachment of a drive device, so that a hidden installation of the drive device means a strong interference with the structure of the frame or the sash and the drive device is perceived as a foreign body in a mounted assembly.

The drive devices are thereby typically provided by the manufacturer in the form of prefabricated ready-to-use units, which are also each Weil fixed as a closed unit to the window or door and coupled to the fitting system. As a closed and firmly connected unit, the respective drive device takes up a certain amount of space that created for a covert assembly once, especially by milling out an ent speaking clearance, in the frame or in the casement who has to. The space required for this is typically so large that the functionality of the window frame or sash, e.g. with regard to its mechanical stability (in particular if the steel reinforcement is interrupted) or the thermal insulation is impaired. In particular, the sash does not provide enough space for a covert installation under certain circumstances. In addition, hidden installation in the rebate area of the window or door usually requires additional accessory components, such as mounting hardware, to secure the drive assembly.

Another disadvantage of a completely hidden mounting of a festverbun dene unit formed drive device is that the assembly is complicated due to the integration in the window or in the door, so that they convincing only by a trained expert and typically only with special work, but not can be done by a layman with simple means. Furthermore, the drive device must be replaced due to their design as a closed unit in the case of service as a whole or completely removed for repair and reinstalled. Because usually it is at least oh- ne complete disassembly of the drive device and in particular for an end user without special knowledge and / or special tools not possible to replace a single defective component. A single com ponent of the drive device to be able to exchange, it may also be advantageous to retrofit the drive device to be advantageous, such as if a possibility for Funkkommu nication with the drive device, for example in the context of a smart home system to be retrofitted by replacing only the electronics or existing means for radio communication to another frequency and / or another communication protocol to be retrofitted.

Such disadvantages of trained as a closed unit Antriebsvorrich device in a similar manner, even if it is mounted on an outer side of the frame, if there is sufficient space, or the sash is mounted, even if the drive device is at least easier to access in this case. However, such a patch assembly is also in addition far disadvantageous, as the drive device protruding from the window or door and thereby not only can be perceived as disturbing, but can also limit the mobility of the wing. In addition, the drive device is at a patch mounting usually the full surface of the sash, whereby vibration and structure-borne noise of the drive device transmitted to the wing and possibly even be reinforced, which can make disturbing noticeable bar.

Furthermore, all components of the drive device together in a unit, which is enclosed in particular by a common housing, can also have disadvantages in the production. For example, housings are used, which are composed of two later interconnected housing shells into which a respective other part of the components of the drive device is preassembled, for example, a motor in a housing shell and the Engine electronics in the other. The arrange in various housing shells th components must then be electrically connected to each other, for example via cable or special, especially flexible, boards, which takes additional time in the final assembly of the drive device to complete.

It is an object of the invention, a drive device for elektromotori's adjustment of the fitting system of a window, a door or derglei surfaces to provide a method for mounting such a drive device and a window or door with such a drive device, the ei ne simplified assembly and a facilitate simplified replacement and avoid the disadvantages of the prior art.

The object is achieved by a modular drive device with the Wish paint of claim 1, by a method for mounting the modular drive device to the features of claim 14 and by a window or door with the modular drive device with the features of claim 15. An.

Advantageous embodiments of the invention will become apparent from the Unteransprü Chen, the present description and the figures.

An essential feature of the drive device according to the invention is that it is modular, ie that it comprises a plurality of units which are basically formed separately from each other, in particular spatially clear against each other are clearly limited, for example, have separate housing, and in particular individually, al so successively, can be mounted or dismounted on the respective window or on the respective door. In this case, although a certain order can be predetermined, so that first a specific unit must be mounted before another unit can be mounted. Due to the modular design However, it is avoided that inevitably all units must be assembled or disassembled together as a single closed unit.

As basically independent units, the modular drive device comprises: a transmission unit comprising an engine, a transmission and a transmission housing in which the engine and the transmission are accommodated, wherein the transmission has an output element which is designed for coupling to a force transmission element , via which the motor is drive-connectable to the fitting system; an electronic unit configured to drive the motor of the gear unit; and a cover unit comprising a drive housing for covering the gear unit and the electronics unit to the outside.

In the engine of the transmission unit is in particular a Elek tromotor. The motor serves to generate a drive torque, which can then be translated by the transmission in terms of its speed or its torque and output via the output element. For this purpose, the output element is adapted to be coupled to a power transmission element which drives the transmission unit to the fitting system, e.g. a provided on the wing chamber gearbox of the fitting system, can connect.

The engine and the transmission are received in the transmission housing, preferably encapsulated in the transmission housing. In other words, the transmission housing preferably surrounds the engine and the transmission at least almost completely, wherein the transmission housing may have openings, in particular at least one opening through which the output element extends or through which the force transmission element can extend to the output element by a drive torque from the engine to outside the gearbox unit to be able to transfer to the fitting system. The inclusion, in particular encapsulation, of the engine and the transmission in the transmission housing not only protects the engine and transmission from contamination, but also supports the modular design of the drive device. Thus, the gear unit can be preferably mounted on the transmission housing independent of other units of the drive device and in particular without accessories such as spe cial mounting hardware on the window or door.

In particular, the gear unit is adapted, regardless of the elec tronic unit and the cover unit in a receptacle, in particular a milled out, to be fastened partially covered on a front side of a frame of the window or the door. In the said frame is preferential, as the sash of the window or the door on which in particular the fitting system is arranged. In principle, however, a fastening on the frame is also possible, in particular if an adjustable loading impact system is provided there. Typically, the frame still has no acceptance of the drive device in which the transmission unit can then be set, so that a recording, in particular a cutout, must be formed from. Basically, however, the frame can also have a corresponding receptacle from the outset, so that not only a cutout must be formed.

As a front side of the respective frame is meant a side which is not arranged in the folding area, but in particular also ter with closed Fens or closed door is accessible. It may be an inside of the respective building facing inside or to a non-half of the respective building facing outside of the frame, where it is preferably an inside. The gear unit is adapted to be fastened to this front side, and consequently initially unfixed, but has, in particular on the gear housing, means such as drilling ments for screws, which allow attachment. The attachment he follows it partially concealed, so that the gear unit on the one hand in the recording in the front of the frame is at least partially received and on the other hand is concealed to the outside, as will be explained below with respect to the cover unit.

The electronics unit is ausgebil det for driving the motor of the gear unit and, for example, a board with appropriate electronics, in particular special example. with a microcontroller. In this case, the Elektronikein unit may also include an electronics housing in which the components of the electric nikeinheit are included and protected. However, this is not necessarily neces sary if the electronics can be arranged sufficiently robust on a board. The electronics unit is adapted to be releasably attached to the transmission unit. In other words, the electronic unit is not connected to the transmission unit from the outset and attached thereto, but this attachment takes place only during assembly of the drive device. In particular, the electronic unit can be connected in this way only indirectly to the frame of the window or the door.

The electronic unit is adapted to be releasably secured to the Getriebeein unit so that it is independent of the gear unit exchange bar. In particular, the electronics unit can be removed from the frame on which it is advantageously fastened via the gear unit, without the gear unit necessarily having to be detached from the frame for this purpose. This allows for easy replacement of the electronics unit in the event of a defect or for a change in the functionality of the drive device. Similarly, the transmission unit can in principle be replaced independently of the electronics unit, such as by the electronics unit is released from the transmission unit, the transmission unit is removed from the frame, another gear unit is mounted to the frame, and the same electric nikeinheit on the other transmission unit is attached. In the case of said partially concealed mounting, the gear unit and / or the electronics unit protrude at least partially out of the receptacle in which the gear unit is mounted. By means of the cover unit, the gear unit mounted in the front of the frame and the electronic unit attached to the gear unit can be covered to the outside. That is, the drive housing of the cover unit encloses the gear unit and the electronics unit not to al len sides, but only has to be designed to cover denjeni gene part of the gear unit and the electronics unit, resulting from the recording in the front of the frame extends. For this purpose, the drive housing may be formed, for example, as a housing shell open at least on one side. Preferably, the drive housing is at least substantially, in particular apart from REQUIRED chen for the attachment elements that may engage in the receptacle or elements located therein Ele, completely outside the frame.

The cover unit may further be adapted to completely close the receptacle in the front side of the frame to the outside, so that the at least partially accommodated therein gear unit and the electronic unit are both protected by geous enough and also do not appear to the outside in appearance. The cover unit protrudes from the front side, but not so far as a drive unit formed as a closed unit would protrude at fully constantly mounted mounting. In this respect, the drive device according to the invention is adapted to be mounted partially concealed. This partially concealed mounting on a front side of the frame has the advantage that the drive device to less space outside the frame claimed and less perceived as a foreign body than an attached mounting and that the drive device is still more accessible than in a completely hidden, in particular from Fold made in the frame integrated assembly. The cover unit is adapted to be detachably attached to the electronics unit, to the transmission unit and / or to the frame. The cover unit therefore does not have to be mounted together with the electronics unit and / or the gear unit on the frame. Rather, first, the gear unit and the electronics unit can be attached to the frame, while the cover, which delimits the modular drive device to the outside, for example, is attached only after the correct installation and function of the gear unit and the electronics unit have been checked. In principle, the cover unit can be designed to be fastened directly to the frame. Preferably, however, the cover unit is designed for indirect attachment to the frame, namely via the electronic unit or the gear unit.

Similar to the attachment of the electronic unit to the gear unit, the cover unit is advantageously designed to be releasably secured. So there is provided a mounting option in which to release the loading fastening anything broken or otherwise irreversibly changed who the must. Thus, the interior of the modular drive device is easily accessible even after mounting from the outside, making a Repara structure or replacement of components of the drive device is simplified.

According to an advantageous embodiment, the electronic unit is designed to be attached to the transmission unit by plugging. For this purpose, corresponding fastening structure can be provided on the electronic unit and / or on the gear unit, which can be designed in particular in the manner of a plug or a socket. The attachment can preferably be done tool los. In this case, the electronic unit and the gear unit can also lock with each other to be secured against accidental release. Preferably, the attachment of the electronics unit to the gear unit also tool los los again.

At the same time, these connections can also be designed for a mechanical coupling of the electronic unit and the gear unit. But it may also be just contacts that are arranged such that they touch each other in other means successful attachment of the electronic unit to the transmission unit. Preferably, the gear unit and the electronic unit are thereby designed to be electrically connected to one another exclusively via one or more terminals, that is to say via terminals which are not yet separated, e.g. via cable, connected to each other who must, but in particular automatically be a related party due to their arrangement, when the electronic unit is attached to the gear unit.

According to an advantageous embodiment, the transmission housing of the transmission unit comprises at least a first and a second housing shell, in which conductor tracks are cast, arranged on the first housing shell angeord designated and in particular attached thereto components of the transmission unit with arranged on the second housing shell and in particular also attached thereto Components of the transmission unit are electrically connected. In particular special to the cast in the first housing shell interconnects and cast in the second housing shell interconnects are arranged so that they are connected to each other when the two Gehäuseschal th are connected together. In this way, a complex process cabling or other electrical connection of the components of the transmission unit, for example via special boards to be avoided. Therefore, it is particularly preferred if the components arranged on the first housing shell are electrically connected exclusively via such conductor tracks to components arranged on the second housing switch.

According to a further advantageous embodiment, the transmission unit tracks for powering the motor and / or signal transmission to the motor or from the motor, which are cast in the gear housing and via at least one electrical connection on an outer side of the Ge gear housing contacted. This connection may in particular be one of the connections described above. By such a configuration, the gear unit can form a self-contained module which is connected via the connection on the outside, e.g. from the electronics unit, can be controlled from the outside. The connector can be in direct contact with the electronics unit when attached to the gear unit. It may be at the terminal, the e.g. can be formed by contact pins, but also act as a connection for a direct connection to a power or bus communication terminal.

Furthermore, it is advantageous if the cover unit is adapted to be attached to the electronics unit and / or the gear unit by placing, in particular additionally by engaging behind a unit formed on the electronic unit or the Getriebeein unit locking edge. The cover unit is preferably without tools on the electronics unit and / or the gear unit can be placed and is preferably also without tools of it again solvable. Further, the cover unit when placed on the electronics unit and / or the Ge transmission unit, in particular by the said engagement behind, engage in order to be secured ge conditions accidental release. By placing the cover unit on the electronic unit and / or the gear unit, the cover unit not only mechanically with the electronic unit and / or the transmission unit are connected ver, but also electrically, such as when the cover unit has a Be dienelektronik, as will be explained below. In this case, the structures provided on the cover unit or on the electronics unit and / or the gear unit for the mechanical attachment by attaching do not have to simultaneously serve the electrical connection. But appropriate contacts or connections can also be provided elsewhere.

According to an advantageous embodiment, the cover unit on a control electronics, which is adapted to be electrically verbun with the electronic unit to receive and receive input from a user to transfer it to the electric nikeinheit, and optionally also driven by the electronic unit to to be, in particular optical, output signals. In particular, the special cover unit may be designed so that the control electronics is automatically connected to the electronics unit electrically, when the Abde ckeinheit is attached to the electronic unit, the transmission unit and / or on the Rah men. For receiving inputs from a user, the Be electronic can, for example, push buttons, other buttons or a berüh insurance sensitive display. At the cover unit, the Bedienelek electronics may be arranged such that it is easily accessible to a user, in example where otherwise usually a window handle would be provided so that the drive device can be controlled manually on site. The control electronics can be limited to merely forwarding inputs, or else be configured to first evaluate the inputs and then output corresponding signals to the electronic unit.

In such an embodiment, it is also advantageous if, in accordance with the manner described above for the electronics unit and the transmission unit be written, the control electronics has at least one electrical connection and the electronics unit has at least one electrical connection, said the electrical connection of the control electronics and the electrical connection of the electronic unit are designed and arranged so that they are electrically connected to each other when the cover unit is attached to the electronic unit or the gear unit. Preferably, the cover unit and the electronic unit are designed to be electrically connected to one another exclusively via one or more such connections.

Furthermore, it is advantageous if the cover unit, similarly as described above for the gear unit, printed conductors for the power supply of the control electronics and / or signal transmission to the control electronics or of the control electronics, which are cast in the drive housing and at least one electrical connection on an inside of the Antriebsgehäu ses are contacted. Thus, no wiring must be required for the electrical connection of the control electronics of the cover unit with the electronics unit. Rather, it may be sufficient to fasten the cover unit in the manner provided for the purpose of also establishing the electrical connection. In this way, the assembly and disassembly of Antriebsvorrich device are simplified and also for an end user, in particular without addi tional aids possible.

According to an advantageous embodiment, the gear unit is ausgebil det, instead of a window handle on the frame, in particular the Flügelrah men of the window or door, attached and coupled via the power transmission element with a gear of the fitting system of the window or the door. In this way, a simple mechanical and efficient drive coupling of the drive device with the fitting system is possible. For provided for a manual operation window handle is simply replaced by the provided for an electromotive actuator drive device, wherein the drive torque is introduced unchanged at the same location, in particular via the same gear of the fitting system in the fitting system. typical scherweise a window handle is drivingly coupled via a square as a power transmission element with the gear of the fitting system. In this respect, it is advantageous if the output element of the transmission of the gear unit is designed to be coupled with a corresponding square.

In order to use the drive device as universally as possible, the drive device is preferably designed according to DIN 18267 for window handles. In this respect, it is preferred that the gear unit has two guides for threaded screws, in particular at a distance of 43 mm, and / or is adapted to be coupled via a square, in particular of 7 mm thickness, with the gear of the fitting system.

By the underside of the gear housing 21 facing surface of each first stage of the two webs 29, a support edge 31 is formed, with which the transmission unit 13 may rest on the front side of a frame of the respective window or the respective door (see Fig .. 5) , The support edge 31 is provided with a damping device in the form of a Weichgummiauflage by which the transmission of Vib rations and structure-borne noise from the transmission unit 13 to the respective window or door is prevented or at least damped. In the gear housing 21, which is formed for example of plastic, printed conductors are poured over which the arranged in the transmission housing 21 electrical or electronic components of the gear unit are electrically connected miteinan, so that no additional wiring within the gearbox begehäuses 21 is required. On its outer side, the gear housing 21, not shown connections for an electrical connection of said tracks to the electronics unit 15, which has corresponding terminals.

The electronic unit 15 is adapted to be simply plugged onto the gear unit 13 and thereby both mechanically stable to the Getriebeein unit 13 attached as well as to be electrically connected via the said connections electrically connected to the transmission unit 13. In this case, the electronic unit 15 substantially, as shown in simplified form in Fig. 1, be formed out as a simple board or have an electronics housing which surrounds the electronics of the electronics unit 15 and protects to the outside. The electronic unit 15 preferably has the shape of a flat plate, as shown.

The cover unit 17 comprises a drive housing 33, which is at least substantially cuboid-shaped, wherein the lower parallelepiped side is open, so that the elec tronic unit 15 and the gear unit 13 Kings are at least partially taken up by this side of the cuboid shape in the drive housing 33 NEN. For this purpose, the drive housing 33 can be mounted on the gear unit 13 in a simple manner, ie in particular without tools. In order to hold the drive housing 33 on the gear unit 13 in the mounted state, 33 locking projections are provided at the lower edges of the side surfaces of the drive housing, which engage behind the webs 29 respectively formed further stage (second stage from below) (see FIG .. 5) , In this respect, a latching edge 35 for securing the cover unit 17 placed on the gear unit 13 is formed on the webs 29 by these second steps. On its upper side, the cover 17 has an operating electronics 37, which is embedded in the top of the drive housing 33. The control electronics 37 is connected to terminals which are arranged on an inner side of the drive housing 33 such that they are electrically connected when mounting the drive unit 17 to the transmission unit 13 with corresponding terminals on the electronics unit 15. In this way, inputs from a user to the control electronics 37 can be transmitted to the electronics unit 15, so that they can be taken into account by the electronic unit 15 for controlling the motor of the transmission unit 13.

The modular design of the drive device 1 1 according to the invention makes it possible to attach said units 13, 15, 17 in succession to a frame of a window or door and, if desired or necessary, to replace them independently of one another. In Figs. 2 to 5, the wing 39 and the frame 41 of a window are shown, on which the drive device 1 1 can be mounted. For this purpose, the sash 43 of the wing 39, the in Fig.

3 already shown, or it must first be formed in the sash 43 as a cutout. Since the modular drive device to 1 1 is formed to a only partially concealed mounting, the receptacle 45 needs, as can be seen in particular in Fig. 5, not to be so deep that the steel reinforcement of the sash 43 is adversely affected by the milling.

In the receptacle 45 then only the gear unit 13 may initially be used such that it is driven via the power transmission element 19 to the chamber gear of a fitting system not shown ge coupled, and for example by screws, nuts or other Flebel and / or clamping mechanisms are attached. In two subsequent steps, the electronics unit 15 can then be plugged onto the gear unit 13 and the latching unit 17 from the electronic unit 15 to the gear unit 13 latching (see sectional view in Fig. 5). From the outside thus results in the image shown in Fig. 2, wherein the drive device 1 1 Although visible, but only slightly above and therefore not disturbing the sash frame 43 is arranged. In this case, the control electronics 37 to the outside for inputs of a user to accessible.

This modular type of assembly, which can preferably be performed without tools or with simp chen tools, such as a screwdriver, also simplifies the maintenance, repair and replacement of individual com ponents. If, for example, the electronic unit 15 is to be exchanged, it is only necessary to remove the cover unit 17 and to detach the electronic unit 15 from the gear unit 13. For replacement or repair of the gear unit 13, the cover unit 17 must be removed and the electronics unit 15 released. However, the transmission unit 13 due to the modularity of the drive device 1 1 then independently of the cover unit 17 and the electronic unit 13 can be repaired or replaced. Thus, the assembly and replacement are considerably simplified by the modular drive device 1 1 according to the invention.
