Definitions

  • the present invention relates to a folding door system.
  • the invention also relates to a method for actuating a folding door system.
  • the main closing edge must be secured in accordance with legal regulations and for general safety reasons in such a way that a danger, in particular with regard to fingers being crushed, is largely avoided for walkers and users of the door in the area of the main closing edges.
  • folding door systems Due to the kinematics of the folding wing doors, folding door systems have the problem that if the main closing edge is protected directly by sensors on the folding side of the door wings, for example by means of light buttons, the folding door can fold into the sensor field when opening and closing Sensor swings in. This leads to self-detection, in which the corresponding sensor detects the opening or closing movement of the folding door within the sensor field and produces a corresponding control signal which, for example, in particular when the door closes, would trigger an unwanted repeated reversing.
  • the main closing edge on the folding side of the folding door system is therefore secured exclusively by means of motor current detection, an increase in the motor current being used when the door hits an obstacle, for example on the hand of a user, in order to correspondingly reverse or stop the door cause.
  • this detection is relatively slow and inaccurate, particularly in the last phase of the closing movement of a folding wing door, so that when a user intervenes in the area of the main closing edge or when a child stays in the area in the last phase of the closing movement, an obstacle is detected by means of the motor current detection cannot be guaranteed. In this way, due to the comparatively high closing forces that are kinematically caused in folding wing doors, there is still a considerable potential for injury.
  • the object is achieved by a folding door system according to claim 1 and a method according to claim 3 or 6.
  • the subclaims relate to advantageous developments of the invention.
  • the object is thus achieved by a folding door system comprising at least one folding door and at least one drive unit for moving the folding door.
  • the drive unit can be controlled by a control unit of the folding door system.
  • the drive unit is designed to move the folding door between the open position and the closed position.
  • the folding door system comprises at least one position sensor for determining the position of the folding door and at least one obstacle sensor for detecting obstacles in a travel area of the folding door.
  • the folding wing door has a monitoring unit, the monitoring unit being set up to receive signals from the position sensor and / or the obstacle sensor.
  • the position sensor is an incremental encoder, which is arranged in particular on a motor shaft of the drive unit.
  • the incremental encoder can be a linear incremental encoder or a rotary incremental encoder, with the rotary incremental encoder being preferred.
  • the rotary incremental encoder has the advantage that it can be designed to be self-calibrating, so that very precise measurement results are available.
  • the incremental encoder preferably has a resolution between 3000 and 35000, in particular between 5000 and 30000, particularly preferably between 7500 and 20,000 pulses per travel path of the folding door between the open and closed positions. This means that there is an optimal resolution to reliably and reliably identify a position of the folding door.
  • the control unit is preferably set up so that a deviation of the folding wing door from the closed position can be detected.
  • a deviation of the folding wing door from the closed position is caused in particular by the influence of wind or by a manual force that a user applies to the folding wing doors. In both cases, however, the folding wing door should remain in the closed position.
  • the fully closed position is thus a target position from which a deviation can be detected by the control unit. If such a deviation is detected, the control unit is set up to control the drive unit such that the drive unit applies an increasing force to the folding wing door in the direction of the closed position as the deviation increases. There is thus a regulation with which the described deviation of the folding door from the closed position is to be minimized.
  • the force to be applied by the drive unit to the folding wing door can be controlled by an electrical power that is output to the drive unit.
  • the aforementioned force is applied to the folding door.
  • a drive unit with a small maximum nominal power can be used, since an electrical energy necessary for locking the folding wing door is only applied when required. In particular, no permanent locking current is required.
  • the monitoring unit is set up to deactivate the obstacle sensor or to disregard the signal from the obstacle sensor if the position of the folding wing door lies outside a predefined activation range.
  • the activation area is in particular a measure of the risk of self-detection of the folding wing door.
  • the folding wing door recognizes itself when the folding wing door projects into a sensor area of the obstacle sensor, so that the obstacle sensor incorrectly considers the folding wing door to be an obstacle.
  • the obstacle sensor is not taken into account or deactivated if there is a risk of self-detection of the folding wing door, ie if the door is outside the activation area.
  • the activation area can be a single area or can comprise several partial areas. In particular, it is provided that the activation area covers a section of the travel path of the Folding wing door corresponds to that which the folding wing door moves to move between the closed position and the open position.
  • the invention also relates to a method for actuating a folding door system.
  • the folding door system corresponds in particular to the folding door system described above.
  • the method comprises the following steps: First, a deviation of a folding door of the folding door system from the closed position is detected. This is done in particular by the position sensor. Again, deviation is to be understood to mean that the folding wing door should remain in the closed position, but is moved out of the closed position by an external influence, such as in particular by wind or by a user. The closed position is therefore a target position from which the folding door deviates. Then, with increasing deviation, an increasing force is applied to the folding door in the direction of the closed position.
  • the invention further relates to a method for actuating a folding door system.
  • the folding door system is in particular a previously described folding door system.
  • the method according to the invention comprises the following steps: First, a position of a folding door of the folding door system is recorded. This is done by the position sensor. In addition, the position of the folding wing door is detected during a movement of the folding wing door, in particular during a closing of the folding wing door. The movement of the folding door is stopped and / or reversed if an obstacle is detected by an obstacle sensor of the folding door system within a sensor field of the obstacle sensor and the position of the folding door is simultaneously within a predefined activation range.
  • the position of the folding wing door preferably corresponds to the position of the main closing edge or the movable end of the folding wing door relative to the guide rail.
  • the main closing edge or the movable end of the folding door is that end of the folding door which is movable along the guide rail for moving the folding door between the closed position and the open position.
  • the sensor signal of the obstacle sensor is only observed when the door is within the activation area.
  • the activation area ensures that the folding wing door does not protrude into the sensor area of the obstacle sensor when the folding wing door lies within the activation area. A false detection of the folding door as an obstacle is therefore excluded.
  • the aforementioned method is advantageously carried out in such a way that the movement of the folding door is continued when an obstacle within the sensor field of the obstacle sensor is detected by the obstacle sensor of the folding door system and the position of the folding door lies outside the predefined activation range.
  • the obstacle sensor would thus output a false obstacle signal, since the obstacle sensor incorrectly recognizes the folding door as an obstacle.
  • the obstacle sensor is therefore ignored if the position of the folding wing door lies outside the predefined activation range.
  • the invention relates to a method for actuating a folding door system.
  • the folding door system corresponds in particular to the folding door system described above.
  • the method comprises the following steps: First, a position of a folding door of the folding door system is recorded. This is done by the position sensor. In addition, the position of the folding wing door is detected during a movement of the folding wing door, in particular during a closing of the folding wing door. An obstacle sensor of the folding door system is then activated if the position of the folding door lies within a predefined activation range. In addition, the movement of the folding wing door is stopped and / or reversed when the obstacle sensor detects an obstacle within the sensor field of the obstacle.
  • the obstacle sensor is only activated if the door is within the activation area. Only in this case can the obstacle sensor work reliably, i. H. only in this case are obstacles that have been detected by the obstacle sensor actually considered as obstacles. An incorrect detection of the folding door as an obstacle is then excluded. In contrast to the previously described method, energy savings are possible because the obstacle sensor can be deactivated when it is not needed. By activating the obstacle sensor as soon as the folding door reaches the predefined activation area, it is nevertheless ensured that the folding door system is monitored.
  • the aforementioned method is preferably carried out in such a way that the obstacle sensor is deactivated when the position of the folding wing door lies outside the predefined activation range.
  • the energy consumption of the obstacle sensor is thus reduced since the obstacle sensor is deactivated when it cannot provide reliable values.
  • this ensures safe and reliable monitoring of the folding door system, on the other hand, the energy consumption that is necessary for monitoring is minimized.
  • control unit increases a power to be output to the drive unit linearly with increasing deviation.
  • the power to be output is, in particular, electrical power, the electrical voltage being particularly advantageously constant.
  • the electrical power can thus be set via the current that is delivered to the drive unit.
  • the control unit reduces the power to the maximum power within a predefined period.
  • a brief overload of the motor is possible in order to generate a necessary locking force, which is why there is no need to provide an oversized motor for the pure drive of the folding wing door.
  • the drive unit which comprises the motor, can be designed to be very compact.
  • the predefined time period is particularly preferably between 5 seconds and 25 seconds, in particular between 5 seconds and 15 seconds, particularly preferably 10 seconds. This is an ideal balance between applying the necessary locking force and avoiding damage to the drive unit. Through the selected periods, it is ensured in particular that a possible overload of the drive unit only has a short-term effect, so that damage is avoided.
  • the control unit detects a deviation over a predefined limit value within a predefined time window. If this is the case, the control unit increases the power by a predetermined increase value. If the predefined limit value is exceeded within the predefined time window, this is due to a strong gust of wind. In order to avoid repeated opening by several gusts of wind, which usually follow the first strong gust of wind, the power is increased by the specified increase value.
  • the specified increase value is, in particular, an increase in the current supplied by 500 mA with a constant electrical voltage.
  • the predefined time window is in particular a maximum of a throughput time of the described method by the control unit, and thus a clock frequency of the control unit. In particular, the predefined time window is a maximum of 10 milliseconds.
  • the predefined limit value is at least 20, in particular 43, pulses from the incremental encoder.
  • the control unit particularly preferably repeatedly reduces the power to be output after a predefined time grid by a predefined reduction value. This takes place in particular until the previously set increase value is balanced. In this way, a middle path is available, so that on the one hand the required locking force for holding the folding door in the closed position is given even in the event of repeated gusts of wind, on the other hand overloading or permanent loading of the drive unit is avoided.
  • the predefined time grid is in particular three minutes, the predefined reduction value being 100 mA. Thus, the current to be delivered to the drive unit is reduced by 100 mA every three minutes within 15 minutes, so that after these 15 minutes the previously used increase value is completely balanced.
  • the reduction value is particularly advantageously smaller than the increase value, the control unit reducing the output to be emitted by the reduction value until the increase by the increase value is canceled.
  • the obstacle sensor is an optical sensor.
  • the optical sensor has, in particular, a transmission frequency between 500 Hz and 5000 Hz, preferably between 750 Hz and 3500 Hz, in particular between 1000 Hz and 2500 Hz.
  • the optical sensor can be an active sensor or a passive sensor, the optical sensor in particular not visible area works.
  • the obstacle sensor preferably generates a sensor field, the projection of which is elliptical or rectangular on a floor surrounding the folding door system. It is provided that a dimension in the direction of a main axis of the projection is between 2 cm and 250 cm, preferably between 5 cm and 100 cm, particularly preferably between 10 cm and 50 cm. A dimension in the direction of the minor axis is preferably between 10% and 95%, preferably between 25% and 75%, particularly preferably between 40% and 60% of the dimension in the direction of the main axis.
  • the main axis is in particular oriented parallel to the passage plane, the secondary axis advantageously being oriented perpendicular to the main axis. In both cases, angular deviations of up to 10% are possible in both directions. In this way, reliable detection of obstacles is achieved, as a result of which contact between the folding door system and the obstacle, in particular the walker, can be avoided.
  • the activation region advantageously extends from a position of a movable end of the folding wing door in the completely closed position to a position of the movable end of the folding wing door in a predefined, partially closed position.
  • the predefined, partially closed position corresponds to a position in which the folding door remains just outside the sensor field described above, in particular the projection described above. If the folding wing door was opened further, it would move into the sensor field, in particular into the projection.
  • One advantage of this definition is a. that the folding door system can determine the predefined, partially closed position itself by opening the folding door from the fully closed position until the obstacle sensor detects the folding door. The fully closed position of the folding door system is particularly present when the folding door is fully unfolded.
  • a further activation area can also be defined in that it extends from the fully open position of the folding wing door to a predefined, partially opened position of the folding wing door.
  • the predefined, partially open position corresponds to the position in which the folding wing door just remains outside the sensor field, in particular the projection. If the folding wing door were opened further from this position, the folding wing door would move into the sensor field, in particular into the projection of the obstacle sensor.
  • the folding wing door remains outside the sensor field of the obstacle sensor during a movement between the predefined, partially closed position and the completely closed position. This prevents erroneous detection of the folding door as an obstacle.
  • the invention relates to a computer program product with a program code stored on machine-readable storage medium for carrying out the method described above when the computer program product runs on a computer.
  • Computer here means in particular the monitoring device or control unit described above.
  • a computer is to be understood as any computing device, in particular also a microcontroller.
  • the folding wing door has in particular a closing force of at most 170 N, preferably at most 165 N, in particular at most 150 N. This closing force is generated in particular by the drive unit. The closing force selected in this way ensures that the folding door system closes safely and reliably.
  • the obstacle sensor advantageously has a response time between 1 millisecond and 200 milliseconds, preferably between 10 milliseconds and 150 milliseconds, particularly preferably between 30 milliseconds and 120 milliseconds. This provides an optimal response time for the obstacle sensor so that an obstacle can be recognized in good time before contact is made with a wing of the folding door system. The contact between the folding door system and the walker, which is usually perceived as very unpleasant by the walker, is thus effectively avoided.
  • the sensor field lies outside a passage plane of the folding wing door.
  • the folding wing door performs a folding-in process or a folding-out process during the opening or closing, the folding-wing door in particular being retracted into the sensor field during the folding-in process or the folding-out process.
  • the monitoring unit advantageously has a clock rate between 10 Hz and 10 kHz, preferably between 20 Hz and 1000 Hz, particularly preferably between 50 Hz and 200 Hz. This means that the aforementioned Method steps are repeated with a clock rate between 10 Hz and 10 kHz, preferably between 20 Hz and 1000 Hz, particularly preferably between 50 Hz and 200 Hz.
  • a clock frequency ensures that the obstacle detection and a possibly necessary reversal of the door movement or a stopping of the door movement can take place sufficiently quickly, so that contact between the folding door and the obstacle is avoided.

  • the first hinge element 20 and the second hinge element 21 have the advantage that they are only attached to an outer region of the first frame 10 and the second frame 11.

This ensures safe and reliable thermal separation. At the same time, a secure and rigid connection of the first hinge element 20 to the first frame 10 and the second hinge element 21 to the second frame 11 is made possible.

Alternatively, this can also be done by a manually applied force on the folding door system 1. In both cases, however, it is undesirable for the folding wing doors 2, 3 to open.
  • the wind load control is thus implemented in such a way that it tries to minimize a deviation of the door position of the folding wing doors 2, 3 from the target position, that is to say from the closed position.

With Such a resolution ensures that the positions of the first folding wing door 2 and the second folding wing door 3 can be reliably detected.
  • the wind load regulation as in Figure 18 essentially comprises three control complexes, which are initialized by a first step S21, a fourth step S24 and a sixth step S26.
  • These rule complexes have different tasks, which are described in detail below:
  • the first step S21 asks whether the folding door system 1 has opened by more than a predefined limit value within a predefined period of time.
  • the predefined time period is in particular the throughput time, thus preferably ten milliseconds.
  • the predefined limit value is advantageously 20, particularly advantageously 43, pulses of the incremental encoder. If such an opening is recognized, the process continues with the second step S22.

  • the power is thus regulated via the current. It is therefore particularly preferably provided that the current delivered to the drive unit 4 is increased in the second step S22.
  • the increase is advantageously 500 mA.
  • the drive unit 4 With the increased current, the drive unit 4 generates an increased closing force, which acts on the first folding wing door 2 and on the second folding wing door 3.
  • This closing force on the one hand causes a locking force when the folding door system 1 is in the fully closed position, on the other hand the closing force causes the doors 24, 25 of the folding door system 1 opened by gusts of wind to close.
  • a time counter is finally started, which is in particular 15 minutes.
  • the first control complex which is initiated by the first step S21, ensures that the repeated folding gates 1 are not opened again in the event of repeated gusts. It is thus determined in the first step S21 whether there is a strong gust of wind, since only a strong gust of wind enables the large opening within the short time. If a strong gust of wind is detected, it can be assumed that this strong gust of wind is followed by further gusts of wind, which mostly have the same strength as the initially detected gust of wind. Thus, by increasing the current that is delivered to the drive unit 4, the folding wing door system 1 can remain in a closed position, even if subsequent gusts of wind act on the folding wing doors 2, 3. Starting the counter in the third step S23 enables the current increased in the second step S22 to be gradually reduced. This reduction is the subject of the second control complex, which is initiated with the fourth step S24.
  • the fourth step S24 asks whether the time counter has been started. If this is the case, the fifth step S25 is carried out at regular intervals. The regular intervals are in particular every three minutes. In the fifth step S25, the current increased in the second step S22 is finally reduced, in particular by 100 mA in each case. The process then continues with the sixth step S26. This is preferably repeated five times, so that after 15 minutes that the time counter is running, the increased current is reduced five times by 100 mA. After the 15 minutes have elapsed, the current increased in the second step S22 is completely reduced again. In this way, overloading of the drive unit 4 is avoided in particular.
  • the third control complex is initiated with the sixth step S26.
  • the sixth step S26 it is determined whether the folding wing doors 2, 3 have a deviation from the fully closed position. As already described, such a deviation is generated in particular by a wind load or by a manual force on the leaves 24, 25 of the folding door system 1. Since the folding door system 1 is to remain in the fully closed position, such a deviation is undesirable.
  • the process continues with the seventh step S27.
  • the current that is output to the drive unit 4 is increased.
  • the increase is particularly linear to the deflection of the folding doors 2, 3 from the fully closed position.
  • a p-controller is thus implemented.
  • the regulation in the seventh step S27 can cause a power output to the drive unit 4 to exceed a nominal power of the drive unit 4.
  • the current delivered then exceeds a predetermined maximum nominal current. This is checked in an eighth step S28. If the maximum rated current is exceeded, the process continues with the ninth step S29. If, on the other hand, there is no exceedance, the process is ended with the termination step S30.
  • the current applied to the drive unit in the seventh step S27 is reduced to the maximum rated current. This takes place in particular within a predetermined period of time, which is advantageously ten seconds.
  • the brief overloading of the drive unit ensures that the folding wing door system 1 remains in the closed position even when there are strong wind gusts.
  • a filigree folding door system 1 can be realized, which nevertheless has a sufficiently powerful wind load control so that the folding door system 1 remains in the closed position even when strong gusts of wind occur.

  • the lower diagram shows a profile of the acceleration.

This means that the folding wing door system 1 is completely closed at a left limit value, while the folding wing door system 1 is closed at one right limit on the axis of abscissa is fully open.
  • the coordinate axes of the diagrams show a speed in the upper diagram and an acceleration of the folding wing doors 2, 3 in the lower diagram.
  • the folding doors 2, 3 behave according to the upper curve of the diagrams. However, if the folding wing door system 1 is closed, the folding wing doors 2, 3 behave according to the lower curves of the diagrams.
  • the shown profiles of speed and acceleration allow the folding door to be opened quickly, while at the same time vibrations within the folding door system 1 can be avoided when opening and closing. Due to the reduction in vibrations, a lowering of the leaves 24, 25 of the folding door system 1 is minimized, which is why they can be at a short distance from a floor. Thermal insulation is thus increased. At the same time, the reduction of vibrations and the resulting minimal lowering of the folding wing doors 2, 3 allow a large opening width to be realized. In particular, this enables a maximum opening width of 2,400 millimeters. This means that when using four wings 24, 25 as shown in Figure 1 was shown, each wing has a width of 60 millimeters.
  • the leaves 24, 25 are braked within the last quarter or within the last third of the travel path of the folding wing doors 2, 3.

  • the folding wing doors 2, 3 have a maximum heat transfer coefficient U D of 3.0 W / (m 2 K).
  • the maximum heat transfer coefficient U D is a maximum of 1.7 W / (m 2 K).
  • the frame 10, 11 of the folding wing doors 2, 3 is in particular made of a material that has a heat transfer coefficient U D between 2.0 W / (m 2 K) and 4.0 W / (m 2 K).
  • the filling element 22 of the folding wing doors 2, 3 comprises a material with a heat transfer coefficient U D between 0.5 W / (m 2 K) and 1.5 W / (m 2 K), preferably of 1.0 W / (m 2 K) ). With these values, the aforementioned low heat transfer through the folding wing door system 1 is made possible.
  • both the first frame 10 and the second frame 11 in the vertical profile elements 12 have thermal separations 31.
  • the thermal separations 31 are, in particular, insulation webs, the thermal separations 31 made of a material with a thermal conductivity coefficient between 0.1 W / (m 2 K) and 0.3 W / (m 2 K), preferably of 0.2 W / ( m 2 K).
  • a modulus of elasticity of the thermal separation 31 is between 400 MPa and 3,000 MPa at 20 ° C., the modulus of elasticity being measured in particular in accordance with DIN 53457.
  • the thermal separation 31 is a material with a coefficient of linear expansion between 0.10 mm / (m K) and 0.25 mm / (m K), preferably between 0.15 mm / (m K) and 0.20 mm / (m K). Sufficient thermal insulation is thus ensured by the thermal separation 31, as a result of which the heat transport through the first frame 10 and the second frame 11 is minimized.
  • the filling element 22 comprises a material with a thermal conductivity coefficient between 0.60 W / (m 2 K) and 0.90 W / (m 2 K), preferably of 0.76 W / (m 2 K).
  • a modulus of elasticity of the filling element 22 at 20 ° C. is between 50 GPa and 90 GPa, preferably 70 GPa.
  • the filling element 22 comprises a material with a coefficient of linear expansion of 0.01 mm / (m K). The heat transport through the filling element 22 is thus also minimized.
  • the filling element 22 is connected to the first frame 10 and the second frame 11 via an adhesive.
  • the adhesive has a tensile strength between 1.0 N / mm 2 and 2.5 N / mm 2 , preferably 1.8 N / mm 2 .
  • the tensile strength can be determined in particular according to ISO 527.
  • the folding wing door system 1 has seals in the form of brushes. These brushes seal the gap between folding door 2, 3 and floor or guide rail 8.
  • the seals in the form of brushes have a trim that has a bristle length between 12 mm and 20 mm, preferably 15.9 mm.
  • a base body of the brushes comprises a round base body, which in particular has a diameter between 2.0 mm and 4.0 mm, preferably of 2.9 mm. In this way, a safe and sufficient sealing of a gap between folding door 2, 3 and floor or guide rail 8 is made possible. Heat transport through this gap is therefore almost prevented.
  • a thermal bridge surcharge between the filling element 22 and the first frame 10 or the second frame 11 is between 0.050 W / (m 2 K) and 0.060 W / (m 2 K), preferably 0.056 W / (m 2 K).
  • a thermal bridge surcharge between the first frame 10 and the second frame 11 and a wall receiving the frame is between 0.050 W / (m 2 K) and 0.060 W / (m 2 K), preferably 0.056 W / (m 2 K).
