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 The invention relates to a fitting for a lift-slide door with a fixed first Fitting part and attached to the movable wing of the door second fitting part and a drive device for the second fitting part.

From the DE 203 12 683 U1 is a lifting-sliding hardware for a window or a door known. This lift and slide fitting has several fittings, one of which is fixed to the frame of the door and the other is fixed to the sliding wing of the door. By means of a drive device which is connected via a toothed belt with the fitting 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.

Of the Invention is based on the object, a comfortable to use and especially by disabled persons operable lift-slide door to create. Furthermore should the door for the commercial and for the domestic ones Area equally good be usable.

These Task is solved with a fitting for a lift-slide door, which has the characteristics of the claim 1 has.

Of the Fitting according to the invention is provided with a programmable controller for the drive device, so not just a simple opening and / or closing movement can be accomplished, but that the wing also with different Speeds, with different opening widths and / or automatically, i. be moved sensor-controlled, semi-automatic or fully automatic can. In the following, different operating modes are shown, the one preferred embodiment concern and for the invention is exemplary.

The Control is according to the invention by means of manual actuated Buttons, by manually pushing the sash on the sash or door handle in the open and / or closed direction (Push and Go), by radio or by means of at least one sensor controllable. 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 Photocell and / or the light curtain is active during closing, where against the radar sensor, the ultrasonic sensor, the infrared sensor and / or the floor mat on opening trip and at closing of the grand piano are active.

fully automatic business

at fully automatic operation (at opening and closing drive by means of an infrared, ultrasonic or radar sensor), the opening drive on the Input of infrared, ultrasonic or radar sensor signal to the controller started. First he drives wing with pre-set reduced release speed, because he is raised. After unlocking, the wing opens the opening speed accelerated. Before the wing the opening end position is reached, it is slowed down and stopped. The wing lingers over the duration the set hold-open time in the open position. Coming during the Hold open time again input pulses, the time is set again (Triggered).

To Expiry of the hold-open time, the closing drive is automatically initiated. Comes during the closing cycle an opening pulse, so the movement is reversed, i. the wing becomes opened again. There are a maximum of three complete cycles (opening and closing) per Minute allowed. Will while the closing drive no opening pulse receive, the door will only closed but not locked. After expiry of an adjustable Waiting time, the locking process is executed. This is to prevent be that at high traffic the locking mechanism unnecessary loaded or the electronics and control is overloaded and the opening times unnecessary increase, there the wing before opening has to be raised every time. The minimum allowable time between two subsidence is e.g. 15 minutes.

On the Infrared, ultrasonic or radar sensor is detected, whether a Person of the door approaching or away or at the door passes. The sensor activates the control only when a Person of the door approaches. This is especially in the commercial sector, for example in restaurants or sales facilities of particular importance since the the door not approximate Audience is not of interest.

obstacle detection

One Obstacle is detected by the fact that the drive current of the drive device when hitting the obstacle over a threshold that exceeds the Setting parameters pre-set opening and closing forces selectable specified is, rises. The wing is then braked heavily. Is the wing in a closing drive, he becomes complete in the open position ascended. Is the wing in an opening trip, he is about 15 cm in the closing direction method.

The Position of the wing when hitting the obstacle is cached. For this purpose points the controller on a data storage. Before the next opening or closing process is then reduced before the obstacle, the speed of the wing, for example, on the unlocking or locking speed. The cache for the obstacle is deleted, if there is no obstacle left. However, if repeated, e.g. three times in a row, the end position due to the obstacle not reached, the controller goes into the interference mode, since a permanent Obstacle in the track of the wing located. In the end positions and in the fault mode is the drive device de-energized and without resistance. The door can be moved easily over the handle manually to be served.

Becomes while the opening or closing movement a drive signal from a sensor other than the infrared or radar sensor recognized, so will the wing stopped immediately. A restart is possible via each drive signal.

Semiautomatic business

in the semi-automatic operation, i. during opening or closing travel via push button or radio remote control, the opening drive is over the Button position "OPEN" started. To reach the opening width becomes the wing stopped. Will during the opening trip the button position "CLOSED" is selected, then becomes the braking process initiated and the wing stopped. Another one Selection of the button position "CLOSED" initiates the closing movement. The wing is closed and locked. Before the end positions, the wing becomes automatic braked.

When crossing the opening and closing forces is increasing the drive current of the drive device via the respective means the setting parameter preset thresholds. This will as mentioned above, an obstacle detected. The wing is braked hard. Is the wing in closing, it is fully rebooted and is the wing in opening trip, he is about 15 cm in the closing direction emotional. The position of the grand piano when hitting the obstacle is cached, and it is as mentioned above, method.

Becomes while the opening or closing movement has received a drive signal from the infrared or radar sensor, so has this signal priority. All other control signals lead to that the wing immediately is stopped. A restart of the wing is possible via each drive signal.

servo operation

At the Servo mode, in which the wing over the Hand lever or handle or pushed on the frame is the Evaluation of the incremental encoder input of the control activated, when the wing in a quiet location. If the wing is operated via the hand lever, Thus, a series of short consecutive signals as drive pulses in the opening direction or closing direction captured and the wing is in the opening direction or closing direction driven. The wing moves with pre-set and possibly reduced opening or closing speed. Will the wing during the opening or closing process stopped by pressing a button, it stops and must be triggered again.

Of the semi-automatic opening process and opening in servo operation, it is aborted after reaching the opening width. Should the wing closed, it must be triggered in the closing direction. This is the wing but only closed or almost closed, but not locked and lowered. The drive device recognizes in this position of the grand piano, whether this in the closing direction or in the opening direction is moved. If it is moved or triggered in the closing direction, then At the incremental encoder pulses are generated in the closing direction, whereby the drive device is caused to rotate in the opposite direction, i.e. in the opening direction is controlled, so that a counterforce is generated. The wing is in the opening direction initiated, then this too will happen recognized 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, for example, from getting up the balcony locks out (lock-out). So that the wing is light initiated can be, the drive control is de-energized in the rest positions. This servo operation can be switched on and off.

Becomes while the opening or closing movement another activation signal (automatic or semi-automatic operation) recognized, so will the wing stopped immediately. A restart is possible via each drive signal.

Further is a parallel operation of the modes servo, semi-automatic or fully automatic operation possible. Dependent of it, about which input the drive signal received, is the respectively described appropriate opening and closing behavior deposited.

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. Here is the Antriebsvorrich Only active 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.

Becomes the wing from an intermediate layer several times in the fully open position driven this is detected by the controller and the intermediate layer is skipped during the next opening process.

Failure mode

in the Failure mode is with a signal tone and / or a light indicator of the fault condition displayed. The drive device is de-energized, so that the wing moves manually can be. By a signal at one of the inputs for semi-automatic operation, Servo control or over a learn button triggers a learn trip. After successful learning journey is the interference mode lifted again. The course of a learning trip will be explained below described.

To A power failure is always carried out a learning trip, if a drive signal at one of the inputs for semi-automatic operation, Servo control or over the learn button is in the controller. Control signals from radio, infrared or solve the radar sensor no learning trip off.

is the door for example about a profile cylinder locks and is locked in this State the control device for the wing nevertheless activated, it is recognized that the drive current is a Exceeds limit, because the wing is not lets move. The controller then gives an alarm signal, for example, with a signal tone out. With multiple activation, the system can switch to the fault mode. This way is about the Control found that the door is locked.

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

Further There is an on / off button over which the drive device secondary is switched off. The drive device is then de-energized and without resistance. The incremental encoder input and the counter remain however active. After switching on, therefore, no learning run must be carried out. The signal inputs Servo, sensor and button for Inside are disabled. The push button input for outside remains however, active, hence the wing at any time from outside via a Key switch, key switch or an electronic switching device can be controlled.

learning trip

The The learning run will be on voltage return and signal input pulse or from the fault mode always in the closing direction started. It serves to close the wing in the closed position initialize and the opening width the door to investigate. The learning trip is preferably done with an accompanying Beep. The wing moves at a speed for example, 0.075 m / s. The current limit is a shutdown force from e.g. 192 N preset on the drive device, which is a Force of 150 N on the wing equivalent. The initialization for the closed position takes place if no pulses from the incremental encoder are received and the current consumption exceeds a preset threshold, i.e. if the wing the closed position has reached. After a waiting time of approx. 2 seconds, the learning journey will start in the opening direction started. To the wing to be able to raise the shutdown force for the Unlocking path to a higher Value, for example, of 300 N superscript. The opening force is after the Unlock again to the above value of 192 N withdrawn.

The Minimum opening width is about 800 mm, with the maximum opening width about 3500 mm. The determined opening width is monitored and must be between these two values. If not achieved will the learning trip again in the closing direction started. With three negative attempts, the controller goes with a Beep in the fault mode and switches the drive device de-energized. With positive learning journey becomes the determined value of the opening width 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 become one of several, in particular six weight classes ordered and classified by 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:
f × opening width × (speed in opening direction) ² .

The braking distance in the closing direction is calculated as:
f × opening width × ((closing speed) ² - (locking speed) ² ).

Of the Braking in the closing direction is initiated before the locking path. It will only be up slowed down to the locking speed.

As already mentioned, the controller has a tutorial that shows the end positions in the closed position and in the open position, i. a first and a second reference point determined and with which also the weight of the wing can be detected. This is the case Lifting the door the drive current of the drive device measured and defined Thresholds compared. about the determined values are assigned to the wing of a weight class, in which all parameters for Speed, acceleration, deceleration etc. are stored. Furthermore In the learning mode, a plausibility check is carried out with which can be determined if the wing is for a door with a certain opening width within a designated weight class, whether the door is the desired opening width owns if the wing the wished Smooth running meets, i.e. the door not warped is installed, and / or whether the wing the reference points determined Repeatable anfährt.

As already mentioned, is due to slight actuation of the Handle moves the drive device, whereby the incremental counter some Receives impulses. This triggers the control, so that the wing is either in the open or in the closed position is moved. A control via radio, for example by means Ultrasound, infrared or other media is also conceivable.

Around to prevent, for example, children with the automatic devices the door the control can be restricted to the fact that the wing of inside only by manual pressing a handle and / or from the outside by a key switch actuated is. As a result, the entire device loses its appeal, can but easily converted back to its original function become. For this purpose, the deadman operation is conceivable.

To step Errors, these are stored in a fault memory in the data store stored the control, and can be read out during maintenance work. Also, new ones can be added to the data store Programs and new limits or parameters are recorded.

at a variant is provided that the control permanently a Measurement of the drive current of the drive device performs and From this an upper limit for the next Movement of the grand piano generated. This upper limit is above a fixed amount above that measured drive current or is a predetermined percentage about that. This avoids that the drive current creeping approaching the limit, for example due to contamination of the guide rails, due to weather conditions or temperature influences, through movements in the building etc. may well be the case.

A Locking 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 recognizes over the measured working current blocking this movable Fitting part and can generate a corresponding signal. This may be a shutdown signal, a warning signal or an information signal.

According to one preferred embodiment is the wing over the Control movable in an intermediate position. The wing is located then in a partial opening width, whereby a ventilation position, Cats opening Apothecary standing, a winter opening or the like can be adjusted. At the winter opening of the opens wing only partially, for example 800 mm, which achieves the effect that the complete opening and closing process faster and thereby the heat loss in the room smaller is. Here you can still set the driving speed slight elevated is. Furthermore can be set, that the intermediate opening only when driving in the opening direction or when driving in the closing direction is taken.

Around an overload To avoid the drive device, this is a temperature sensor and a shutdown device provided so that in case of overload, the drive device a predetermined time is turned off, so that it can cool down again.

The Control can according to the invention with a Signal transmitter for different control states be provided, the signal transmitter optical and / or acoustic Display means comprises. Furthermore, can the control states, in particular deviations from normal states in a fault memory be stored, then in the context of service or maintenance is read out. Based on the data read malfunction be prevented.

Finally is still a reset device provided, in particular a reset button, with which the controller can be brought into a state, so that her afterwards can carry out a learning journey. The reset button is usually operated when the controller has a disorder indicating or after a power failure.

Further Advantages, features and details of the invention will become apparent the following description, with reference to the drawing a particularly preferred embodiment is described in detail. The illustrated in the drawing as well as in the description and in the claims mentioned features individually for themselves or be essential to the invention in any combination.

In the area of the upper crossbar 18 of the fixed wing 14 there is a box 20 , in which a stationary fitting (not visible) and a drive device are housed. In and on the sliding wing 16 there 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 there is a handle 24 , the Indian 1 takes the closed position and is oriented vertically upwards. In the 2 the handle takes 24 the open position and extends in a horizontal direction. In the 2 is also recognizable that the upper cross member 18 or at the bottom of the upper cross member 18 a sensor 26 is attached, which is designed for example as a light curtain, radar sensor or infrared sensor. He monitors the entrance of the door 10 and provides signals for control. Also located on the left vertical spar 28 of the frame 12 a button 30 for manual control of the sash 16 ,

In the 3 is the manual mode of the door 10 by means of the button 30 shown. The button 30 has two feeler elements with which the opening travel and the closing travel can be initiated. For semi-automatic operation, it is sufficient if the button 30 is pressed once. Then the wing completes 16 automatically his opening or closing drive. Deadman operation requires the button 30 during the entire journey of the grand piano 16 being held.

In the operating mode "Push and Go" the wing becomes 16 at its rear vertical spar 32 initiated 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, 50 mm in front, remain standing (lock-out). Will the wing 16 on its front vertical rail 34 triggered, he automatically performs the opening trip to the open position. All closing trips can be made using the button 30 , by abutment of the vertical spar 34 , by means of the handle 24 , by radio or by activating the sensor 26 being stopped.
