Description

The invention relates to a sliding door system according to the preamble of patent claim 1.

From the DE 39 40 762 A1 an automatic sliding door system that can be used in an escape and rescue route is known with at least one sliding panel which can be driven by a drive device. The drive device is controlled by an electronic control device. In such sliding door systems, it is necessary that the sliding leaf after activation of the control device with an emergency signal and / or failure of the mains power supply to release an escape route as soon as possible and fully opened, but at least within a predetermined maximum time also a predetermined minimum opening width, for example, 80% of the full Opening width reached. In order to prevent unauthorized passing of the sliding door system, it can be locked in at least one operating state, for example the so-called night mode, by a locking device. The actuation of the locking device via a device for switching operating states of the sliding door system, here specifically via a program switch.

Such program switches are characterized by the fact that certain switching operations, often even all switching operations, can be made only by authorized persons, for example by key operation or via a code input device. This means that the sliding door system locked in at least one operating state can not be unlocked by persons who are not authorized to operate the program switch. This in turn could mean that these are for operating the program switch unauthorized persons in a hazardous situation could not leave the danger location, for example the building interior, through the sliding door system. Automatic sliding doors for use in escape routes may only be locked if there are no emergency requirements for the escape door as an escape and rescue route. This is usually the case when there are no more persons in the building or when a different escape route has been identified for these persons. In turn, if other, the leaving the building enabling operating conditions are set by means of the program switch, while the exit of the building by all, ie by unauthorized for operating the program switch persons is possible, but there is no protection when setting these operating conditions by the lack of locking unauthorized passage.

The invention has for its object to provide a sliding door system, which meets both the requirements of escape and rescue routes as well as ensures protection against unauthorized passage.

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

The sliding door system can be securely locked in certain operating states so that protection against unauthorized access is available. Characterized in that a release device is provided, which is used to unlock the locking device and the opening of the sliding leaf, if necessary, especially in an emergency, each person who must pass through the leading through the locked sliding door escape route, make an unlocking of the sliding door system and make an opening of the sliding sash.

By a redundant, in particular failsafe training of the release device reliable unlocking and opening the sliding door system even when an error in the enabling device are still possible. Redundancy can be achieved by the multiple holding of components, in case of failure of a component whose function is taken over by another, similar component.

Devices for self-monitoring of the enabling device and / or the control device can be provided. As a result, additional security is achieved since faults in the enabling device and / or the control device are automatically detected and reactions to these faults are triggered automatically.

The unlocking device may have a manually operable actuating device, which may be formed, for example, as emergency button.

Alternatively or additionally, the enabling device may have an electrically controllable actuating device, which may have, for example, an electrical signal input. As a result, a transmission of an electrical emergency signal from an external device, such as an emergency or a central monitoring device is possible.

The locking device is advantageous according to the working current principle operable to arrive at the fall in the supply voltage in any case in the unlocked state. The locking device may be arranged in a locking circuit, to which a supply voltage is applied. For unlocking the locking circuit can be interrupted by a switching contact, for example by a switch designed as an opener. One-fault safety can be achieved, for example, by virtue of the locking circuit being multipolarly interruptible by the disconnecting device, wherein at least two switching contacts designed as openers which can be actuated by the disconnecting device can be arranged in the locking circuit, so that even if one of these switching contacts fails there is the possibility of interrupting the interlocking circuit.

The control device has at least one input for a drive signal, for example a drive voltage. The control device is designed so that the activation or deactivation of the drive voltage at the input causes an unlocking and opening of the sliding leaf by the drive device. The drive voltage is via at least one drive voltage circuit connectable to the entrance. In the Ansteuerspannungsstromkreis at least one actuatable by the enabling device switching contact can be arranged.

The switching contacts of the locking circuit and the switching contact of the Ansteuerspannungsstromkreises can be actuated together by the enabling device, so that an actuation of the enabling device can cause both an activation of the locking device as well as a control Mi least one of the inputs.

As with the operation of the release device, an opening of the previously locked sliding sash is connected, this should be displayed. For this purpose, the enabling device can have at least one display device for indicating the actuation of the enabling device, which can be designed as an optical and / or acoustic display. Alternatively or additionally, the enabling device may have at least one signal output for outputting a signal indicating actuation of the enabling device, which signal may be transmitted, for example, to a higher-level monitoring device, e.g. in a building control center. The signal output can be designed as an interface, for example for a bus system. The display device and / or the signal output may also be located at another suitable position in or on the sliding door system, e.g. in the control device, arranged, in particular be integrated.

There may be an activatable by an output signal release relay, with which a temporary activation of the locking device and a temporary control of at least one of the inputs is effected. The release relay can be designed as a time relay, ie cause a limited to a predeterminable time activation of the locking device. For this purpose, at least one further switching contact which is designed as an opener and can be actuated by the release relay and at least one further switching contact designed as a make contact and likewise actuatable by the release relay can be arranged in the locking circuit. The output signal, which may be connectable to the release relay for a predetermined period of time may be generated by a switch device. The switch device can be designed as a key switch, code input device or the like. The described, temporary activation may be useful if the sliding door system is already closed and locked, but still has to be passed by authorized persons.

In Fig. 1 a sliding door system 1 is shown in front view. The sliding door system 1 has two sliding sashes 2, which are displaceably guided in a stationary rail in the region of a drive device 5 and can be driven by the drive device 5. Side of the sliding sash 2 two fixed fields 3 are arranged, which limit a passage area 4 of the sliding door system 1. In the opened state, the sliding leaves 2 release the passage area 4, which lies between a region 11 arranged in front of the sliding door system 1 and an area 12 arranged behind the sliding door system 1.

The various operating states of the sliding door system 1 are adjustable by means of a program switch 6, which is arranged in the vicinity of the sliding door system 1 stationary. It can be provided that this setting possibility exists only for authorized persons, for example by key operation or via a code input device in order to avoid unwanted instability of operating states of the sliding door system 1.

Above the passage area 4 of the sliding door system 1 at least one sensor 7 is arranged, which can be designed as a motion detector. The sensor 7 detects a detection area located in front of the sliding door system 1, wherein on the other side of the sliding door system 1, a further sensor can be arranged, which detects in a corresponding manner a detection area located behind the sliding door system 1.

The arranged in front of the sliding door system 1 area 11 may be formed as a potential danger area, such as the interior of a building and arranged behind the sliding door 1 area 12 as Fluc htbereich so that an escape route with an escape direction 10 through the passage area 4 of the sliding door system 1 can lead , The sliding door system 1 must be designed for this purpose so that the sliding sash 2 after activation of the control device (SE) with an emergency signal and / or failure of the mains power supply to release the escape route as soon as possible and fully opened, but at least within a predetermined maximum time also a predetermined minimum opening width , For example, 80% of the full opening width.

In order to achieve a secure locking of the sliding door system 1 in certain operating states, for example, in the event that the sliding door system 1 can not be permanently supervised, it is provided that the sliding sash 2 of the sliding door system 1 via a (not shown in FIG. 1) Locking device VE are locked in their closed position. The locking device VE can be actuated via the program switch 6, so that it is effective in at least one operating state of the sliding door system 1 in the locked state. In order to ensure unlocking of the locking device VE in case of failure of the electrical energy supply network to which the sliding door system 1 is connected and to release the escape route leading through the passage 4 of the sliding door system 1, it is provided that the locking device VE can be operated with the working flow principle, ie the locking device VE is energized in its locking position and in the absence of energization automatically in their unlocking Position arrived. The operable with the working current principle locking device VE may have as an electric actuator, an electromagnet or an electric motor, which acts upon energization of the locking element of the locking device VE, for example, a locking bolt in its locking position. Furthermore, the operable with the working current principle locking device VE may have a return device for the locking element, which acts in the absence of energization of the electric actuator, the locking element in its unlocking position and may be formed, for example, as a mechanical energy storage.

In the vicinity of the sliding door system 1, in this embodiment, on a post arranged adjacent to the fixed field 3, an enabling device 8 is arranged, by means of which the locking device VE can be unlocked. In addition, the release device 8 can also cause an opening of the sliding sash 2 by the drive means 5. The enabling device 8 has a manually operable actuating device 9, which is designed, for example, as emergency button. The activation of the enabling device 8 can be displayed in various ways: firstly by optical and / or acoustic signal transmitters in the area of the sliding door system 1 and / or on the other hand from the sliding door system 1 remote location via a signal output, which in the enabling device 8 or elsewhere the sliding door system 1 is arranged and formed, for example, as an interface for a bus system. Thus, a signal indicating the actuation of the enabling device 8 can be output to a central monitoring device via the signal output.

2 , a first embodiment of the release circuit of the sliding door system 1 according to the invention is shown schematically. The control device SE has an electrical connection, which leads to a switchable output A _SKV , which can be at ground potential, for example, a supply voltage U ₂ . At these two terminals, a locking circuit SK _{V is switched} , in which the electrical actuator of the locking device VE is located. When the interlock circuit SK _V is closed, the electric actuator of the locking device VE is thus the one Supply voltage U ₂ , whereby the actuator acts on the locking element of the locking device VE in its locking position. By switching the switchable output A _SKV , for example, separation from the ground potential, leads by the then no longer present energization of the electrical actuator of the locking device VE to trigger the locking device VE. The switching of the switchable output A _SKV can be triggered, for example, by pressing the program switch 6 or by a program sequence of the control device SE.

To interrupt the energization of the locking device VE is in the locking circuit SK _V also designed as an opener switching contact S _{3 is} arranged, which is actuated via the actuating device 9 of the enabling device 8.

The example designed as a motion sensor sensor 7 is shown only schematically in this embodiment, since only its function in Ansteuerspannungsstromkreis SK _{A should be} displayed here. About the Anste u-erspannungsstromkreis SK _A is a drive voltage U ₁ over several subcircuits SK _A1 , SK _A2 , SK _A3 on several inputs E ₁ , E ₂ , E _{3 of} the control device SE aufschaltbar. The sensor 7 has a arranged in the subcircuit SK _A1 , designed as a normally closed switch contact S ₄ , which opens upon activation of the sensor 7 and thus interrupts the subcircuit SK _A1 . When this causes disconnection of the control voltage U ₁ from the drive E of the drive device 5 serving input E ₁ , the opening of the sliding sash 2 by the drive device 5 is triggered by the control device SE. Upon closing of the switching contact S ₄ , ie in the absence of Anste u-erung the sensor 7 and thus recurrent control voltage U ₁ at the input E ₁ is closed by the control device SE, possibly after the expiration of a predetermined, in the control device SE storable hold time, a closure of the sliding sash 2 effected by the drive means 5.

In addition, via the actuating device 9 of the enabling device 8, together with the above-described switching contact S ₃ , two more, each formed as an opener switch contacts S ₁ , S _{2 can be} actuated, which are arranged in the Ansteuerspannungsstromkreis SK _A. The opening of the switching contact S _{1 of} the disconnecting device 8 effected via the actuating device 9 of the disconnecting device 8, which likewise lies in the partial circuit SK _A1 in series with the switching contact S4 of the sensor, thus also causes an opening of the sliding sash 2 by the drive device 5.

The free inputs E ₂ , E _{3 of} the control device are used for error safety, specifically the verification of the sensor 7, the enabling device 8 and the associated wiring:

When driving the sensor 7 - in addition to the already described switching contact S ₄ in the subcircuit SK _A1 - also located in the other subcircuit SK _A3 , designed as a normally closed switch contact S5 of the sensor 7 is opened and thus the drive voltage U ₁ of the input E ₃ of Control device SE switched off. The signals applied to the inputs E ₁ , E ₃ (voltages) are compared. A deviation of the signals applied to the inputs E ₁ , E ₃ from each other means a fault, for example, one of the switching contact S ₄ , S _{5 of} the sensor 7. The control device SE can then with a safety reaction, for example with an emergency opening of the sliding sash 2 and optionally with an error message, respond to this error.

Upon actuation of the actuating device 9 of the enabling device 8, the already described switching contact S ₁ in the partial circuit SK _{A1 is opened} - and the switching contact S ₂ located in the further partial circuit SK _A2 , and thus the drive voltage U _{1 is} switched off from the input E _{2 of} the control device SE. The signals applied to the inputs E ₁ , E ₂ signals (voltages) are compared. A deviation of the signals applied to the inputs E ₁ , E ₂ from one another means a fault, for example one of the switching contacts S ₁ , S ₂ . The control device SE can then react to this fault with a safety reaction.

3 , a further embodiment of the release circuit of the sliding door system 1 according to the invention is shown schematically. The control device SE has an electrical connection, which leads to a connection to ground potential GND a supply voltage U ₃ . At these two terminals, a locking circuit SK _{V is switched} , in which the electrical actuator of the locking device VE is located. When the locking circuit SK _V is closed, the supply voltage U ₃ is applied to the electrical actuator of the locking device VE, as a result of which the actuator acts on the locking element of the locking device VE in its locking position. For multi-pole interruption of the energization of the locking device VE two formed as normally closed contacts S ₉ , S ₁₀ are arranged in the locking circuit SK _V , which are actuated together via the actuator 9 of the enabling device 8. The multi-pole interruption of the locking circuit SK _V is used to ensure the single-fault, since in an assumed defect (non-opening) of the switching contacts S ₉ , S _10, an interruption of the locking circuit SK _V by the other switching contact S ₁₀ , S ₉ takes place.

In addition, via the actuating device 9 of the enabling device 8, together with the above-described switching contacts S ₉ , S ₁₀ , two further, each designed as NO contact switches S ₁₁ , S ₁₂ operable, which are each arranged in a Ansteuerspannungsstromkreis SK _A4 , SK _A5 . A drive voltage U _{4 is} applied to an input E _{4 of} the control device SE via the drive voltage circuit SK _A4 , ie when the drive voltage U _{4 is applied to} the input E ₄ , the control device SE triggers opening of the sliding leaves 2 by the drive device 5. The same applies to the input E _{5 of} the control device SE, to which a drive voltage U _{5 can be} applied via the drive voltage circuit SK _{A5 in} order to trigger an opening of the sliding leaves 2 by the drive device ₅ via the control device SE. The drive voltage U ₄ , U ₅ can be the same, but advantageously come from different voltage sources, so that always a failure of a voltage source still a control of the control device from the other voltage source is possible. The actuation of the release device 8 leads to a closing of the switch contacts S ₁₁ , S ₁₂ and thus to apply the drive voltages U ₄ , U ₅ to the inputs E ₄ , E _{5 of} the control device SE. The multiple presence of the inputs E ₄ , E ₅ and the switching of the control voltages U ₄ , U ₅ over several switching contacts S ₁₁ , S ₁₂ is used to ensure the single-fault, since the defect (non-closing) of the switch contacts S ₁₁ , S _12th an activation of a drive voltage U ₅ , U ₄ via the other switching contact S ₁₂ , S ₁₁ takes place.

The activation of the release device 8 thus leads to unlocking the locking device VE and triggered via the control device SE opening the sliding sash 2 by the drive means 5. The release device 8 is provided for emergency situations in which the passage area 4 of the sliding door system 1 is used as an escape route, i. After actuation of the release device 8, the sliding leaves 2 remain after their opening in the open state until an authorized person resets the enabling device 8. For this purpose, the actuator 9 of the enabling device 8, a protective device, e.g. having a sealed cover, although an actuation, but not a reset of the actuator 9 allows.

However, in order to allow a temporary opening possibility of the locked sliding door system 1, ie with subsequent closure and locking of the sliding sash 2, in addition to the enabling device 8 in addition a short-term release device is provided. This has a release relay KF, which can be controlled by a trigger signal A _KF . The trigger signal A _KF can be issued by a (not shown) switch means, which may be formed as a key switch, code input device or the like. The release relay KF can be designed as a time relay, that is, after its activation, the relay remains in the triggered by the control switching state for a predetermined time and automatically switches back to its original switching state after this time.

In the locking circuit SK _{V designed} as an opener, actuated by the release relay KF switching contact S _{6 is} arranged, which interrupts the locking circuit SK _V when driving the release relay KF and thus causes a cancellation of the energization of the locking device VE. Furthermore, by the release relay KF two each arranged in the Ansteuerspannungsstromkreisen SK _A4 , SK _A5 , designed as normally open switch contacts S ₇ , S _{8 can be} actuated, which close when driving the release relay KF the Ansteuerspannungsstromkreise SK _A4 , SK _A5 and thus via the control device SE an opening of the sliding sash 2 by the drive device 5 trigger. After the activation of the release relay KF, the switching contacts S ₆ , S ₇ , S _{8 reach} their starting position. As a result, the A n-control voltage circuits SK _A4 , SK _{A5 are} interrupted, which, optionally after expiration of a predetermined, in the control device SE can be deposited open-holding time, a closure of the sliding sash 2 by the drive means 5 causes. Furthermore, the locking circuit SK _{V is} closed, whereby the sliding sash 2 can be locked again after reaching their closed position.
