Abstract

The commercial or domestic entry (10) has a fixed part (14) and a sliding part (16) which is attached to a support mounting (22) in the fixed head (18). The door may be set in motion automatically by a sensor or by a push button. A handle (24) governs the door action.

Description

The invention relates to a fitting for a sliding door with a stationary first fitting part and a fixed to the movable wing of the door second fitting part and a drive device for the second fitting part.

From DE-U-203 12 683 a lifting-sliding fitting for a window or a door is known. This lift-slide fitting has several fittings, one of which is fixed to the frame of the door and the other on the sliding Wing of the door is attached. By means of a drive device which is connected via a toothed belt with the fitting part attached to the wing, the wing is moved between a closed position and an open position. In the closed position, the wing is in its lowered position and is first raised from this and then moved into the open position.

Further fittings are known from DE-C-36 43 326, DE-A-199 49 453, DD-A-116 885 and EP-B-548 505.

The invention has for its object to provide a comfortable to operate and above all operated by disabled persons sliding door. In addition, the door should be equally well usable for the commercial and for the domestic area.

This object is achieved with a fitting for a sliding door having the features of claim 1.

The fitting according to the invention is provided with a programmable controller for the drive device, so that not only a simple opening and / or closing movement can be completed, but that the wing with different speeds, with different opening widths and / or automatically, ie sensor-controlled, semi-automatic or fully automatic can be moved. In the following, different modes of operation are described which relate to a preferred embodiment and which are exemplary for the invention.

The control is according to the invention by means of manually operable buttons, by manually pushing the sash on the casement or door handle in the open and / or closing direction (push and go), controlled by radio or by means of at least one sensor. The sensor is a light barrier, a light curtain, a radar sensor, an infrared sensor, an ultrasonic sensor, a pressure-sensitive floor mat or a touch sensor.

The light barrier and / or the light curtain is active when closing, where are active against the radar sensor, the ultrasonic sensor, the infrared sensor and / or the floor mat during opening and closing the wing.

Fully automatic operation

In fully automatic operation (when opening and closing by means of an infrared, ultrasonic or radar sensor), the opening travel is started via the input of the infrared, ultrasonic or radar sensor signal at the control. First, the wing moves at a preset reduced release speed as it is raised. After unlocking, the wing is accelerated to the opening speed. Before the wing reaches the opening end position, it is braked and stopped. The sash lingers in the open position for the duration of the set hold-open time. If input pulses reappear during the hold-open time, the time is set again (triggered). After expiry of the hold-open time, the closing drive is automatically initiated. If an opening pulse occurs during the closing drive, the sequence of motions is reversed, ie the sash is opened again. A maximum of three complete cycles (opening and closing) per minute are permitted. If no opening pulse is received during the closing drive, the door is only closed but not locked. After expiration of an adjustable waiting time, the locking process is executed. This is to prevent that at high frequency, the locking mechanism unnecessarily burdened or the electronics and control is overloaded and increase the opening times unnecessarily, since the wing before opening each time must be raised. The minimum allowable time between two subsidence is eg 15 minutes.

The infrared, ultrasonic or radar sensor detects whether a person is approaching or removing the door or walking past the door. The sensor activates the control only when a person approaches the door. This is particularly important in the commercial sector, for example in restaurants or retail establishments of particular importance, since the door is not close to the public is not of interest.

obstacle detection

An obstacle is detected by the fact that the drive current of the drive device when hitting the obstacle over a threshold, which is preset selectable via the setting parameters preset opening and closing forces increases. The wing is then slowed down considerably. If the wing is in a closing drive, it is fully driven to the open position. If the wing is in an opening travel, it is moved by approx. 15 cm in the closing direction.

The position of the wing when hitting the obstacle is cached. For this purpose, the controller has a Data storage on. Before the next opening or closing operation, the speed of the wing is then reduced in front of the obstacle, for example to the unlocking or locking speed. The obstacle cache is cleared when there is no obstacle. However, if several times, for example three times in succession, the end position is not reached due to the obstacle, the controller goes into the interference mode, since there is a permanent obstacle in the track of the wing. In the end positions and in interference mode, the drive device is de-energized and without resistance. The door can be easily operated manually via the handle.

If, during the opening or closing movement, a drive signal is detected by a sensor other than the infrared or radar sensor, the wing is stopped immediately. A restart is possible via each drive signal.

Semi-automatic operation

In semi-automatic operation, ie during the opening or closing travel via push-button or radio remote control, the opening travel is started via the push-button position "OPEN". After reaching the opening width of the wing is stopped. Becomes during the opening travel, the button position "CLOSED" is selected, the braking process is initiated and the wing stopped. A renewed selection of the button position "CLOSED" initiates the closing movement. The wing is closed and locked. Before the end positions, the wing is braked automatically.

When the opening and closing forces are exceeded, the drive current of the drive device rises above the respective threshold values preset by means of the adjustment parameters. As a result, as already mentioned above, an obstacle is detected. The wing is braked hard. If the sash is in closing, it is fully retracted and if the sash is in opening travel, it is moved by approx. 15 cm in the closing direction. The position of the wing when hitting the obstacle is cached, and it is, as already mentioned above, proceed.

If a drive signal from the infrared or radar sensor is received during the opening or closing movement, this signal has priority. All other control signals cause the wing to stop immediately. A restart of the wing is possible via each drive signal.

servo operation

In servo mode, where the vane is pushed over the hand lever or handle or on the frame, the evaluation of the incremental encoder input of the control is activated when the vane is at rest. When the wing is operated by the hand lever, a series of signals that are in short succession are detected as drive pulses in the opening direction or closing direction, and the vane is driven in the opening direction or the closing direction. The sash moves with preset and possibly reduced opening or closing speed. If the sash is stopped during the opening or closing process by pressing a button, it stops and must be pushed again.

The semi-automatic opening process and the opening in servo operation is aborted after reaching the opening width. If the sash is to be closed, it must be pushed in the closing direction. However, the wing is only closed or almost closed, but not locked and lowered. The drive device detects in this position of the wing, whether this is moved in the closing direction or in the opening direction. If it is moved or triggered in the closing direction, pulses are sent to the incremental encoder in the closing direction is generated, whereby the drive device is caused to be driven in the opposite direction, ie in the opening direction, so that a counterforce is generated. If the wing is triggered in the opening direction, then this is also detected via the incremental encoder and the drive device supports the opening movement. This means, in effect, that the locking stroke is not executed. This way you can prevent yourself from locking yourself out on the balcony, for example (lock-out protection). So that the wing can be easily pushed, the drive control is de-energized in the rest positions. This servo operation can be switched on and off.

If another activation signal (automatic or semi-automatic mode) is detected during the opening or closing movement, the sash is stopped immediately. A restart is possible via each drive signal.

Furthermore, a parallel operation of the modes servo, semi-automatic or fully automatic operation is possible. Depending on which input the drive signal is received, the respectively described corresponding opening and closing behavior is stored.

dead man's

Furthermore, a deadman mode can be activated, in which the drive device can be controlled only via the button inputs on the inside and outside. The drive device is active only as long as long as the button is pressed. A fully automatic or semi-automatic operation is also not possible as a servo operation. The set speeds are maintained. When the button position is "OPEN", the sash moves in the opening direction, with the sash stopping immediately when the button is released. The same applies to the button position "CLOSED". If both buttons are pressed simultaneously, the sash stops. In the end positions and intermediate layers, the drive device is de-energized. The wing can be moved by hand at any time without additional resistance. This operating mode is used, for example, in the private sector, although additional protection via light barriers can be dispensed with.

If the wing is driven several times from an intermediate layer into the fully opened position, this is detected by the controller and the intermediate layer is skipped during the next opening process.

Failure mode

In the fault mode, the fault condition is indicated by a signal tone and / or a light indicator. The drive device is de-energized, so that the wing can be moved manually. A learn trip is triggered by a signal at one of the inputs for semi-automatic operation, servo control or via a learn button. After a successful learning run, the fault mode is canceled again. The course of a learning trip is described below.

After a power failure, a learn run is always performed when a drive signal is present at one of the semi-automatic, servo, or teach-in inputs in the controller. Control signals from the radio, infrared or radar sensor trigger no learn run.

If, for example, the door is locked by means of a profile cylinder and the control device for the wing is nevertheless actuated in this locked state, it is recognized that the drive current exceeds a limit value since the wing can not be moved. The controller then issues an alarm message with a signal tone, for example. With multiple activation, the system can switch to the fault mode. This way will through the controller found that the door is locked.

If photocells are connected, the closing process is monitored. If the light pulse is interrupted, immediately a braking process is initiated, and moves the wing in the open direction. This applies to all operating modes except for deadman operation.

Furthermore, an on / off button is provided, via which the drive device is switched off secondarily. The drive device is then de-energized and without resistance. However, the incremental encoder input and the counter remain active. After switching on, therefore, no learning run must be carried out. The signal inputs servo, sensor and button for inside are deactivated. However, the exterior of the push-button input remains active, so that the wing can be controlled from the outside at any time via a key switch, key-operated switch or an electronic switching device.

learning trip

The learn run is always started in the closing direction when the voltage returns and the signal input pulse or from the fault mode. She serves the wing in Initialize the closed position and determine the opening width of the door. The learning journey is preferably carried out with an accompanying signal tone. In this case, the wing moves at a speed of, for example, 0.075 m / s. The current limit is preset to a shut-off force of eg 192 N on the drive device, which corresponds to a force of 150 N on the wing. The initialization for the closed position takes place when no pulses from the incremental encoder are received and the current consumption exceeds a preset threshold value, ie when the blade has reached the closed position. After a waiting time of approx. 2 seconds, the learn run is started in the opening direction. In order to lift the wing, the disconnection force for the Entriegelungsweg is set to a higher value, for example, 300 N. The opening force is reset after unlocking to the above value of 192 N.

The minimum opening width is approx. 800 mm, whereby the maximum opening width is approx. 3500 mm. The determined opening width is monitored and must be between these two values. If this is not achieved, the learn run is started again in the closing direction. In the case of three negative attempts, the controller enters the fault mode with a signal tone and switches the drive device off.

With a positive learning run, the determined value of the opening width is read into the data memory.

To determine the weight of the wing, the drive current is measured after the unlocking of about 100 mm and read this value into the data memory. From this, the braking distance is determined. With a displacement of approx. 500 mm, the drive current is measured again and read into the data memory. This value is needed to adjust the shut-off force, if necessary, for heavy-duty blades. The values read into the data memory are assigned to one of several, in particular six weight classes, thereby classifying the wing. These weight classes are assigned different parameters for the speed, load shedding, braking behavior, starting behavior, etc. The required braking distance depends on the wing mass and wing speed. After the learning run, the braking distance is calculated from the parameters for the door speed and the determined opening width and set.

The braking distance in the opening direction is calculated as: $$\mathrm{f}\times \ddot{\mathrm{O}}\mathrm{opening\; width}\times {\left(\mathrm{Speed\; in}\ddot{\mathrm{O}}\mathrm{opening\; direction}\right)}^2\mathrm{,}$$

The braking distance in the closing direction is calculated as: $$\begin{array}{l}\mathrm{f}\times \ddot{\mathrm{O}}\mathrm{opening\; width}\times ({\left(\mathrm{Speed\; in\; the\; closing\; direction}\right)}^2-\\ {\begin{array}{c}\left(\mathrm{Speed\; when\; locking}\right)\end{array}}^2)\end{array}$$

The braking operation in the closing direction is initiated before the locking path. It is only decelerated up to the locking speed.

As already mentioned, the control has a learning program with which the end positions in the closed position and in the open position, ie a first and a second reference point determined and with which also the weight of the wing can be detected. For this purpose, when the door is raised, the drive current of the drive device is measured and compared with defined threshold values. The determined values are used to assign the wing to a weight class in which all parameters for speed, acceleration, deceleration, etc. are stored. In addition, a plausibility check is performed in the learning mode, with the can be determined whether the wing for a door with a certain opening width within a designated weight class, whether the door has the desired opening width, whether the wing meets the desired smooth running, ie not the door is distorted installed, and / or if the wing repeatedly approaches the determined reference points.

As already mentioned, by slight operation of the handle, the drive device is moved, whereby the incremental counter receives some pulses. This triggers the control, so that the wing is moved either in the open or in the closed position. An activation by radio, for example by means of ultrasound, infrared or other media, is also conceivable.

In order to prevent, for example, children from playing with the automatic devices of the door, the control can be restricted in that the wing can be actuated from the inside only by manually operating a handle and / or from outside by a key switch. As a result, the entire device loses its appeal, but can easily be changed back to its original function. For this purpose, the deadman operation is conceivable.

If errors occur, they are stored in a fault memory in the data memory of the controller, and can be read out during maintenance work. In addition, new programs and new limits or parameters can be imported into the data memory.

In a variant, it is provided that the controller permanently performs a measurement of the drive current of the drive device and generates an upper limit value for the next movement of the blade from this. This upper limit is above a fixed amount above the measured drive current or is a predetermined percentage above it. This avoids that the drive current creeping approaching the limit, which may well be the case, for example, due to contamination of the guide rails, by weather or temperature influences, by movements in the building, etc.

A locking of the door takes place in that the movable fitting part is blocked in the wing, e.g. by means of a profile cylinder, a bolt or the like. The controller detects a blockage of this movable fitting part via the measured working current and can generate a corresponding signal. This can be a shutdown signal, a warning signal or an information signal.

According to a preferred embodiment, the wing is movable over the controller in an intermediate position. The wing is then in a partial opening width, whereby a ventilation position, cat opening, Apothekerstellung, a winter opening or the like can be adjusted. At the winter opening, the sash only partially opens, for example, 800 mm, whereby the effect is achieved that the complete opening and closing operation is faster and thus the heat loss in the room is smaller. It can still be adjusted that the driving speed is slightly increased. In addition, it can be set that the intermediate opening is taken only when driving in the opening direction or when driving in the closing direction.

To avoid overloading the drive device, this is provided with a temperature sensor and a turn-off device, so that in case of overload, the drive device is switched off for a predetermined time, so that it can cool down again.

The controller may be provided according to the invention with a signal generator for different control states, wherein the signal generator has optical and / or acoustic display means. Furthermore, the control states, in particular deviations from normal states, can be stored in a fault memory, which can then be used as part of service or maintenance work is read out. Based on the data read malfunctions can be prevented.

Finally, a reset device is provided, in particular a reset button, with which the controller can be brought into a state so that it can then perform a learning journey. The reset button is usually operated when the controller indicates a fault or after a power failure.

Further advantages, features and details of the invention will become apparent from the following description in which, with reference to the drawing, a particularly preferred embodiment is described in detail. The features shown in the drawing and mentioned in the description and in the claims may each be essential to the invention individually or in any combination.

In FIG. 1, the reference numeral 10 designates a lifting-sliding door as a whole, which has a frame 12, a fixed wing 14 and a displaceable wing 16. In the area of the upper transverse spar 18 of the fixed wing 14 is a box 20, in which a stationary fitting part (not visible) and a drive device are housed. In and on the displaceable wing 16 is a movable fitting part 22 which is connected, for example via a belt drive with the drive device and the fixed fitting part. In addition, the drive device is provided with a programmable controller.

On the movable wing 16 is a handle 24, which occupies the closed position in Figure 1 and is oriented vertically upwards. In the figure 2 takes the handle 24, the open position and extends in a horizontal direction. In addition, it can be seen in FIG. 2 that a sensor 26 is attached to the upper cross member 18 or to the underside of the upper transverse member 18, which sensor is designed, for example, as a light curtain, radar sensor or infrared sensor. It monitors the entrance of door 10 and provides signals to the controller. In addition, located on the left vertical beam 28 of the frame 12, a button 30 for the manual control of the wing 16th

FIG. 3 shows the manual operating mode of the door 10 by means of the pushbutton 30. The button 30 has two sensing elements with which the opening travel and the closing travel can be initiated. For semi-automatic operation it is sufficient when the button 30 is pressed once. Then the wing 16 automatically completes its opening or closing drive. When Totmannbetrieb the button 30 must be maintained during the entire ride of the wing 16.

In the operating mode "Push and Go" the wing 16 is triggered at its rear vertical spar 32 and he completes the closing automatically. He can either move completely into its closed position or at a short distance to its closed position, for example, 50th mm before, stop (lock-out). If the wing 16 is triggered at its front vertical spar 34, it automatically completes the opening drive to the open position. All closing trips can be stopped by means of the button 30, by abutment of the vertical beam 34, by means of the handle 24, by radio or by activating the sensor 26.

FIG. 5 shows a speed-distance diagram for the wing 16. In the first movement section 36, the displaceable wing 16 is raised and displaced at a low release speed V1. In the second movement section 38, the displaceable wing 16 is in the raised position and is moved at a higher speed V2. In position S8, the wing 16 has its open position. From there it is first moved to close with a high return speed V4 to position S3 in the closing direction and is moved and lowered at reduced speed V3 to the closed position.

During the learning run, the end position for the closed position is detected and the maximum opening width S9 is determined. The distance between the open position S8 and the maximum opening width S9 is the safety clearance required for pinch and pinch protection. Thereby not only pinching between the rear vertical beam 32 of the wing 16 and the rear vertical spar 40 of the frame 12 is avoided, but also a pinching between the front vertical spar 34 of the sliding wing 16 and the front vertical spar 42 of the fixed wing 14th
