Abstract

In an automated process to operate an emergency exit with a sliding door, the door drive has an electronic control unit linked to downward directed sensors that monitor the last fifth of the door travel. In normal operation the presence of an obstacle in this last sector results in immediate arrest or reversal of the door operation. The drive system is coupled to a house emergency system which if activated allows for the doors to open, but disallows closure in the event of an obstruction in the last one fifth of travel.

Description

The invention relates to a method for operating an automatic sliding door system according to the preamble of patent claim 1.

From the DE 196 53 026 A1 is a method for operating an automatic sliding door system with at least one sliding leaf, which is drivable by means of a driven by an electronic control device drive means, known. A monitoring area, which is passed by a vertical side closing edge of the sash when opening the sash, is monitored by a sensor device by the sensor device in the presence of an obstacle in this monitoring area outputs an obstacle signal indicating this state to the controller, whereby in normal operation, an immediate deceleration and Stopping or reversing the sliding sash is effected. The sliding door system can be used in an escape and rescue route by the drive device is designed so that in emergency operation of the escape and rescue route after activation of the control device with an emergency signal is released by the sliding leaf moves by the control device from its closed position in the direction of its open position becomes. The obstacle signal is superior to the emergency signal, ie the immediate braking of the sliding leaf also takes place in the presence of the emergency signal. However, this may mean that reaching a required minimum opening width of the door within a predetermined maximum time is not guaranteed in all cases.

From the DE 10 2004 031 897 A1 Another method for operating an automatic sliding door system is known. In the presence of a presence of an obstacle in the monitoring area, which at opening the Sliding wing is passed from a vertical Nebenschließkante the sash, indicating signal, the sliding sash is decelerated by the controller after passing through the acceleration phase and a shortened high-speed phase in a braking phase to a lower low speed and moves at this low speed in its full open position. Although this method ensures the achievement of a required minimum opening width of the door within a predetermined maximum time, there is the residual risk that obstacles are caught by the secondary closing edge of the moving at low speed door and possibly trapped.

The invention has for its object to provide a method for operating an automatic sliding door system, which ensures both a reliable release of the escape route and a minimization of the outgoing of the minor closing edge of the sliding panel opening danger.

The object is solved by the features of patent claim 1. The subclaims form advantageous embodiments of the invention.

When the obstacle signal occurs during the emergence of the emergency signal, the sliding leaf is braked selectively to a standstill in a stop point, the stop point exclusively at 80% of a minimum opening width or between 80% of the minimum opening width and for a sliding door system that can be used in an escape and rescue route fully disclosed. The sliding leaf is not braked immediately when the obstacle signal occurs, but first operated further in the opening direction until one of the aforementioned criteria is met.

This ensures both reliable release of the escape route and minimization of the danger emanating from the secondary closing edge of the sliding panel opening, since the opening movement, ie the release of the escape route, is continued despite an optionally present obstacle signal, the stopping at the stop point jamming the obstacle avoided and clearing the danger area of the minor closing edge is possible. The stop point is reached until the end of a predetermined for a deployable in an escape and rescue route sliding door system maximum time in which the sliding sash must have reached at least the minimum opening width.

In order to make it possible to clear the area to be passed by the secondary closing edge, the sliding panel can only be moved into its full open position at a lower low speed after the expiry of a predefinable downtime, for example after a standstill of 15 seconds.

If the stop point is already between the predetermined minimum opening width and the full open position, this final complete opening may possibly be dispensed with.

In the event that the sliding leaf stops at a stop point between 80% and 100% of the predetermined minimum opening width, the sliding leaf must be moved at least to its minimum opening width after the end of the downtime, but may remain here, ie. he does not have to be driven to his full disclosure.

In the following, exemplary embodiments are explained in more detail in the drawing with reference to FIGS.

FIG. 1 shows an automatic sliding door system 1 with two sliding leaves 2 and two fixed fields 3. The sliding leaves 2 can be driven by a drive device 4 arranged above the sliding leaves 2 and the fixed fields 3, for example driven by a sensor (not shown) which is an approaching person detected. The sliding sash 2 have approximately the same width as the adjacent fixed fields 3. The sliding door system 1 is suitable for use in an escape and rescue route by the drive device 4 is formed so that the sliding sash 2 after activation of the control device with an emergency signal which be generated, for example, by a smoke or fire alarm or by a manually operated emergency button, be opened so that the sliding sash 2 within a predetermined maximum time (eg 3 seconds) reach a predetermined minimum opening width X _M (eg 80% of the full opening width).

2 to 5 , the speed V of the sliding sash 2 over the opening width x (FIGS. 2 to 4) or over the time t (FIG. 4) for its opening movement in the case of an emergency opening of the sliding door system 1 is shown. The closed position of the sliding sash 2 is designated by the opening width X ₀ , and the complete open position of the sliding sash 2 is designated by the opening width X ₂ . The maximum achieved speed of the sliding sash 2 is designated by v ₂ . In the first exemplary embodiment according to FIG. 2 , the minimum opening width X _{M of} the sliding leaves 2 is equal to the complete opening width X ₂ , while in the second embodiment according to FIGS . 3 and 4 the minimum opening width X _{M is} smaller than the complete opening width X ₂ .

In the event that there is no obstacle in the surveillance area of the sensor devices 5 monitoring the secondary closing edges of the sliding sashes 2, the sliding sashes 5 pass through the speed profile indicated by the reference numeral 7, ie in the acceleration phase s ₁ the sliding sashes 2 are moved within the acceleration time t ₁ to Time T ₁ accelerates from standstill to the high speed v ₂ , which they maintain in the high-speed phase S ₂ for the high-speed time t ₂ to time T ₂ . This is followed by a braking phase S ₃ , in which the sliding sash 2 are braked to their standstill within the braking time t ₃ until their time T ₃ from their maximum speed v ₂ and then have reached the maximum opening width X ₂ . This ensures the fastest possible opening of the sliding sash 2 in the event of an emergency opening of the sliding door system 1, wherein the specification that the sliding sash 2 reach the required minimum opening width X _M within a predetermined maximum time is reliably fulfilled.

In the event, however, that there is an obstacle, in particular a person in the monitoring area of the sensor device 5 monitoring the secondary closing edges of the sliding leaves 2, the sensor device 5 generates an obstacle signal and the sliding leaves 2 pass through, while an emergency signal is present, designated by the reference numeral 8 speed curve. With regard to the acceleration phase s _1, this corresponds to the velocity course 7 of the obstacle-free movement. However, the phase covered by the maximum speed v ₂ is limited to a shortened one of the high-speed phase s ₄ , which is traversed in the shortened high-speed time t ₄ until the time T ₄ , to which - within the past the braking time t ₅ up to the time T ₅ continuous braking phase s _{5 followed} . After passing through the braking phase s ₅ , the speed of the sliding sash 2 is reduced to zero in a stop point X ₁ . The position of the stop point X ₁ must be at least 80% of the minimum opening width X _M. It is essential here that the acceleration phase s ₁ , the shortened high-speed phase s ₄ and the braking phase s ₅ are traversed within the predetermined maximum time, for example 3 seconds, so that the required minimum opening width X _{M of} the sliding sash 2 is then at least safely reached. The sliding leaves 2 remain for a predeterminable standstill time t ₆ in the stop point X ₁ . Within this time, an evacuation of the area to be passed by the secondary closing edge of the sliding sash 2 is possible.

In the embodiment according to FIG. 2 , the minimum opening width X _M corresponds to the complete open position X ₂ , ie the stop point X ₁ is 80% of the minimum opening width X _M. Following the described stop, the sliding sashes 2 must continue after the end of the downtime t ₆ until their full open position X _{2 are} moved to reach the minimum opening width X _M. This movement can be performed with the low speed v ₁ in a low speed phase s ₆ in the low speed time t ₇ . Shortly before reaching the full open position X ₂ , a deceleration takes place from the low speed v ₁ along the speed curve 7 of the obstacle-free movement, so that the sliding sashes 2 are decelerated to a standstill when the maximum opening width X ₂ is reached.

In the embodiment according to FIGS . 3 and 4 , the minimum opening width X _{M is} smaller than the complete open position X ₂ .

3 , the braking of the sliding sash 2 is such that the stop point X _{1 is} at 80% of the minimum opening width X _M , ie after expiry of the downtime t ₆ , the sliding sash 2 must continue at least until the end of the downtime t ₆ Minimum opening width X _{M to be} moved. Here, the sliding sash can be stopped again to reduce the risk of trapping obstacles, but alternatively also be spent along the dashed lines shown speed profile 8 'in its full open position X ₂ .

4 , the braking of the sliding sash 2 takes place so that the stop point X _{1 is} at the complete minimum opening width X _M , ie after expiry of the idle time t ₆ , the sliding sash 2 need not move further at least to its full open position X ₂ ie, during the low speed time in FIG. 5. Alternatively, however, the sliding sashes 2 can also be brought here along the speed profile 8 'shown in dashed lines into its complete open position X ₂ .

Also in normal operation, the opening movement of the sliding sash 2 of the sliding door system 1, that is, in the case of an approaching person controlled opening of the door, are monitored by the sensor device 5 and at the same speeds, as described above, take place.
