[Detailed description of the invention] Adjustment drive device for window or door fittings The present invention is an adjustment drive device for window or door fittings, and the window or door fittings are controlled by a planetary gear system. is an electric motor that drives an output mechanism that can be connected to a door fitting, and an electric motor that drives an output mechanism that can be connected to a door fitting. Humanly actuable operating parts, electric motors, and planetary gears that are driven independently of the motor. It has a holder that combines the device, output mechanism, and operation part into one component unit, and has a The star gear system consists of the following components: a sun gear with external teeth; Rotatably supported on a coaxial hollow gear with internal teeth and a planetary gear holder. In addition, there is a type that has a small number of planetary gears (both have one planetary gear) that mesh with the sun gear and the hollow gear. Regarding the ceremony.

According to DE-A-3223808, windows with pivoting and tilting fittings are manually operated. Integrating an additional electric motor adjustment drive into the handgrip provided for This is well known. The adjusting drive can be, for example, a geared motor with a planetary gearing. The output shaft of the geared motor also forms the rotation axis of the hand grip, and the output shaft of the geared motor simultaneously forms the rotation axis of the hand grip Connected to the drive rod system of the tilting bracket. The reaction moment of an electric motor is It is guided through a hand grip to a fixed plate fixed to the window shoji frame. Swivel tilting metal In order to manually operate the tool, first, the hand grip is connected to the fixed plate in a non-rotatable manner. The pin joint that is attached to the must be removed at the same time.

Separate adjusting drive for actuating the window with pivoting and tilting fittings integrated in the window grip A variation of is known from DE-A-3915569. This adjustment In the drive, the electric motor is connected via a spindle drive and a rack transmission. to rotate the output mandrel of the window grip. Output for manually operating window fittings The window grip coaxial to the mandrel is disabled using a locking key for motor operation. It is locked in the child frame.

The locking key must be activated before the handgrip can be manually rotated. Must be.

What is common in both of the aforementioned adjustment drives is that they are provided for human actuation. The handgrip must be unlocked before it can be activated. be. The unlocking process does not give the correct result from the normal operation type of the handgrip. I can't do it. This makes operation difficult. In addition, electric The motor is integrated into the hand grip, and the hand grip is relatively large. . Electric motor operation is common and human operation is required, e.g. in emergency situations or with adjusting drives. In many use cases, the exception being in the case of machine failure, fixed mounting on a window or door An adjusting drive that can be adjusted is advantageous. In contrast, human-operable controls The working part should be as small as possible and placed on the shoji of a window or door where you want to make it inconspicuous. An adjusting drive according to the present invention is known from DE-A-3824531. This adjustment drive In the drive system, a high-speed, low-voltage electric motor drives the window through a multi-stage cylindrical gear transmission. Or drive the drive rod binion of the door fitting. Multi-stage for manual operation of metal fittings A pawl clutch is provided between the cylindrical gear transmission and the drive rod pinion. the nail The drive rod pinion is disconnected from the multi-stage cylindrical gear transmission through the clutch and Connected to the driver. In this case as well, in order to switch the pawl clutch, the hand lever must be Before applying the pivoting movement of the bar to the drive rod pinion, the hand lever is first pressed. There must be.

The object of the invention is that it can be fixedly connected to a window or a door and is nevertheless extremely simple. It is an object of the present invention to provide an adjustment drive for a window or door fitting that is simply operable.

Starting from the above-mentioned adjusting drive, the object of the invention is to provide a component, a sun gear. and the entire planetary gear holder is common relative to each other and relative to the holder part. The component is rotatably supported around an axis of rotation, and an electric motor connects the component. in permanent driving connection with a first component of the component, the operating part being a second component of said component; a third component of the output mechanism is in constant driving connection with the output mechanism; the component is connected to a self-locking device, and the self-locking device is A first drive coupling between the motor and the first component for the swing drive. locks away from the component and the second component is in the inactive position of the operating part. The solution is that it is lockable relative to the holding part.

Such adjustment drives are in particular typically electrical motor actuation of window or door fittings. , suitable for use cases where human interaction is the exception. Holds the electric motor of the regulating drive The holding part can be fixedly connected to the window or door, and the operating part can be attached to it. It can be constructed accordingly to be small and possibly unobtrusive.

Between the output mechanism connected to the window or door fitting and the electric motor, and between the output mechanism and the operation A mechanical latch, such as a pawl clutch or similar, is provided between the parts. It is provided. This is advantageous for the operational safety of the adjusting drive and also Facilitates detection of the end position of the adjusting drive. This type of switching is possible in the drive path. The absence of a latch simplifies the configuration and allows the use of a transmission with a large reduction ratio. Even in this case, it is possible to construct the adjusting drive compactly.

Planetary gearing advantageously has at least a small electric motor, so that a relatively small electric motor is sufficient. It is also configured as a reduction gear for the drive path leading from the electric motor to the output mechanism. It is. However, it is of further advantage that the drive coupling of electric motors can also be It is a planetary gear device that also exhibits a deceleration effect in the driving connection of the operating parts. in this case The output mechanism is drivingly coupled to the planetary gear carrier. This configuration uses an electric motor If the operating part is drivingly connected to the hollow gear and the operating part is drivingly connected to the sun gear, then This becomes particularly simple in the configuration of .

A self-locking device acting on the drive coupling of the electric motor in the adjusting drive according to the invention. The position is the component connected to the electric motor of the planetary gear transmission during human operation. component automatically absorbs the reaction moment of the planetary gear transmission. Ru. A self-locking device is a self-locking device for electric motors in the form of a brake motor. It can be a brake that is automatically released upon connection. What is easy is Electric motor self-locking transmissions, especially self-locking worm transmissions It is configured to be drivingly coupled to a planetary gear transmission via a position. This kind of transmission The device can also be used to reduce the motor rotation speed.

In an advantageous embodiment, the operating part is lockable to the holding part. This club Specifically, the crank is held coaxial with the axis of rotation of the planetary gear transmission component. of planetary gear transmissions without additional intermediate gearing. act on a component assigned to the drive path of a planetary gear transmission. Can be used to drive directly.

In an advantageous embodiment, the crank has a base part which is rotatably mounted on the holding part. and a grip portion pivotably supported on the base portion. The grip part In the inactive position, the base part is non-rotatably locked to the holding part. The grip part When the motor is swiveled about the pivot axis from the inactive position to the operative position, the motor During operation, the lock that absorbs the reaction moment of the planetary gear transmission is released. . This considerably simplifies the human operation of the adjusting drive.

The incorrect operation is caused by a crank whose grip part is pivotally attached to the base part via a swivel hinge. The crank arm is configured as an arm, and the crank arm is connected to the pivot shaft at the end remote from the pivot hinge. The grip pin protrudes laterally from the crankshaft. protrudes toward the casing in the inactive position of the system and engages with the locking notch in the retaining part. This is particularly true if the In the inactive position, the grip pin hidden. The grip bin has a crank arm for manual actuation of the adjustable drive. It is only exposed when it is rotated. At the same time and forcibly, this locks the The use will also be cancelled.

Alternatively, the second component of the planetary gear transmission can be kept in the inactive position of the operating part. Relative to the holding part, the second component is It can be locked by being combined with the holding part. For example, the locking clamp rotational moment, which can be a clutch or a slipping clutch or similar A limiting device is a device in which the reaction moment generated by an electric motor is supported by a holding part. It is designed to be used. On the other hand, in the case of manual operation, the If so, a rotational moment exceeding the limit value of the rotational moment limiter is generated. , whereby the second component of the planetary gear transmission is manually rotated. Ru. The variation mentioned above is said to be operated without any special operation of the operating part. This is not the only advantage (in some cases, the grip member on the operating part can be removed). , thus preventing manual actuation of the adjusting drive by unauthorized persons. It also has advantages.

The planetary gear transmission can be a single-stage transmission, but advantageously two stages drive each other. A plurality of dynamically coupled planetary gear transmission stages are provided, each of the planetary gear transmission stages The components include a sun gear with external teeth, a hollow gear with internal teeth and the aforementioned at least one planetary gear in mesh with the sun gear and the hollow gear is rotatably supported; It is possible to have a planetary gear holder. In this case, electric motor and operation The part is drivingly connected to the first planetary gear stage. In this configuration as well, the first The planetary gear holder of the planetary gear stage forms the transmission output of the gear stage. this place In this case, the planetary gear carrier is preferably directly connected to the sun gear of the subsequent second planetary gear stage. is connected to. This second planetary gear transmission stage also advantageously has its planetary gear carrier. If it is directly connected to the output mechanism, it acts with a deceleration effect.

The two-stage planetary gear transmission having the above-mentioned configuration has a structure for receiving the planetary gear transmission. the retaining portion having an axially confined chamber in the end wall, the interior of which is generally cylindrical; It's especially easy to configure if you have one. In this case, the first planetary gear transmission stage is mounted on the first end wall. A sun gear and an operating part non-rotatably coupled to the sun gear are rotatably supported. It will be done. On the other hand, the second end wall has an idler of the planetary gear transmission stage of the second planetary gear transmission stage. A star gear holder and an output mechanism non-rotatably coupled are rotatably supported.

The hollow gear of the first planetary gear stage is advantageously fitted for the drive connection to the electric motor. additionally having external teeth projecting inwardly from the first end wall at a distance from the first end wall; A chamber is provided in the axial direction between the ring shoulder and the ring shoulder.

In contrast, the hollow gear of the second planetary gear stage is non-rotatably arranged in the chamber. It is. In the configuration described later, the sun gear of the second planetary gear transmission stage is connected to the first planetary gear. It is non-rotatably connected to the planetary gear holder of the gear transmission stage. In this case, the first The planetary gear holder of the moving gear stage is rotatably supported on the stationary intermediate wall of the chamber. Can be done. On the other hand, the planetary gear holder of the first planetary gear transmission stage is connected to the second planetary gear. The first end wall and the second planetary gear transmission are loosely connected in the axial direction, including the sun gear of the gear transmission stage. The construction is particularly simple if it is arranged between the planetary gear holder of the moving stage. Either In order to reduce wear even in the case of planetary gears and planetary gear holders or end walls, A sliding disc can be inserted between them.

According to the abovementioned concept of the invention, the electric motor and the operating part can be used in various ways of the planetary gear transmission. Act on components. The second concept of the invention is for electric motors and emergency operation. The actuating parts located on the same component of the planetary gear It concerns an adjusting drive of the type mentioned above. Even under this second concept, the aim of the present invention is The target can be fixed and attached to the window or door and nevertheless very easily The purpose of the invention is to produce an adjustment drive for an operable window or door fitting. Later? The second concept of the invention allows for a particularly simple adjusting drive, as will be explained in the following.

For this purpose, the electric motor and the operating part are the first components of the planetary gear transmission. The electric motor is connected to a self-locking device.

The self-locking device is the first component for the electric motor and the swing drive. from the first component side. planetary gear transmission The second component of the is non-rotatably locked relative to the retaining part and A third component of the star gear transmission is in permanent driving connection with the output mechanism.

Drive path between the self-locking device and the first component of the planetary gear transmission In addition, a torque limiting device is arranged. Even in this case, the locking clamp Rotating moment, which can be a clutch or slipping clutch or similar The limiter limits the driving rotational moment of the electric motor to the first controller of the planetary gear transmission. components, especially its sun gear. This sun gear has a central location. Particularly suitable for motor drive. On the other hand, when operating manually, it starts from the operating part. The rotational moment developed in the sun gear exceeds the limit value, so the sun gear is It is rotated manually against the self-locking action of the locking device. This invention In this case, the limit moment of the rotational moment limiter is It is only necessary to generate a locking moment, and it is configured to completely lock. It is clear that there is no need.

In the adjusting drive according to the second concept of the invention, it is also advantageous if the planetary gear carrier is , forming the third component of the planetary gear transmission, drivingly coupled to the output mechanism. do. The first component can be a hollow gear, but advantageously the sun gear It can be a car.

The self-locking device is also preferably a self-locking transmission, especially a cell. It can be a flocking worm transmission.

The electric motor of the regulating drive of the type mentioned at the beginning is usually equipped with a limit switch. The electric motor is held in the end position via this limit switch. It has become so. This limit switch is operated by a regulating drive. It is conceivable that the system could be activated by a connecting rod on a window or door fitting. But this Such limit switches must be specially installed and The precision with which electric motors can be controlled via switches is often not sufficient.

In a third concept, the object of the invention is an adjustment drive for a window or door fitting, which is relatively Controls electric motors, especially those with a small number of components and small space requirements In order to do this, it is possible to detect the position of the adjusting drive.

This purpose is to provide the holding part with at least one, in particular a gear coupling, coaxially with respect to the output mechanism. A control disc is rotatably connected to the output mechanism through the , the outer periphery of which forms a cam surface, and at least one control disk in the holding part; This is achieved by placing a control switch that scans the cam surface. It was. The holding part, the control disk and the control switch form one structural unit and the The component unit can also be precisely adjusted to intermediate positions between the end positions of the output mechanism.

This means that the adjusting motor is positioned not only in the closed and swivel-open positions but also in the tilt-open position. This is particularly useful in the case of pivoting and tilting fittings. Gear between output mechanism and control disc The coupling is designed to reduce speed and provide large control over a relatively small output mechanism rotation angle. Disk rotation angles can be assigned.

The control disc can be arranged coaxially to the output mechanism, but advantageously it can be arranged on the axis of rotation of the output mechanism. In particular, multiple arranged coaxially in the form of a pile, non-rotatable but removable. It is advantageous if control discs are provided which are connected to one another. For example, each other In this way, the indexable and adjustable control disc can be adjusted individually depending on the application. Adjusted in steps. For gear coupling the output component of the planetary transmission For example, external teeth are provided directly on the planetary gear holder, and in some cases intermediate teeth are provided with external teeth. Through the gear, it can mesh with a gear non-rotatably installed on the control disc pile. Ru.
