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. Furthermore, the installation of at least one intrinsically safe, ie redundant and self-monitoring motion detector is required in the direction of escape.

By this arrangement, the escape direction is fixed. In some applications, the sliding door system, this may be sufficient, for example, if the sliding door system limits a building exterior wall and thus leads the escape direction to the outside. In many applications, however, a sliding door system can also be arranged inside buildings, especially in large public buildings, such as shopping centers, railway stations or airports. In such buildings, it may happen that a clear escape direction in the passage area of the sliding door system can not be fixed, but - depending on the specific danger situation - a reversal of the direction of escape may be required to ensure evacuation of the specific area of danger. The sliding door system described must be elaborately rebuilt or retrofitted.

From the DE 196 51 947 C1 is another automatic, in an escape and rescue route usable sliding door system known. Since this system is to form a smoke-tight closure in case of fire, additional rotary blades are provided, which must be manually pivoted by the persons passing the escape route persons against the force of a return device in the direction of escape. By the rotary wing a single escape direction is fixed.

From the US 5,142,152 and the WO 01/23816 A1 Sliding door systems are known in each case, which - in a conventional manner - in the operating modes "one-way operation" or "Closed" are operable.

The EP 0 803 632 A1 shows a sliding door system with self-monitoring sensors.

The invention has for its object to further develop a generic sliding door system such that it is universally applicable.

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

The fact that the control device has a switching device for switching the direction of escape, the sliding door system is universally applicable. Even subsequent changes to the desired direction of escape, which can be permanent (eg in a conversion of the building) or short term (at different conceivable hazard scenarios), can be easily with the sliding door system according to the invention, ie without conversion or retrofitting the sliding door system, as all for the universal Availability required components are already standard in or on the sliding door system are available.

For each direction of escape at least one sensor is present which monitors a detection area in front of the door system in the direction of escape and cooperates with the control device. The sensor can be designed as a motion detector.

A high reliability of the sensor is achieved by this is designed to be redundant and / or self-monitoring. 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. With self-monitoring, malfunctions of components can be automatically detected and reactions to these malfunctions can be triggered automatically.

The control device can cooperate with a device for setting and changing operating states of the sliding door system. This device can be designed as a program switch, which is arranged in the vicinity of the sliding door system. In order to avoid incorrect operation of the sliding door system, the operation of the program switch or at least certain settings only by authorized persons is possible, for example via a key switch and / or a code input device.

The switching device for switching the direction of escape can be controlled manually, for example by the described device for setting and changing operating states of the sliding door system, i. the program switch. However, this may only be done by authorized persons, so that appropriate measures such as key switch or code input device are required.

Alternatively or additionally, the switching device for switching the direction of escape can be controlled automatically. For example, this can be done via at least one further sensor which automatically recognizes certain dangerous situations that require activation of an emergency opening of the sliding door system and / or a changeover of the escape direction and emits a corresponding signal to the control of the sliding door system. Advantageously, this further sensor is designed to be redundant and / or self-monitoring.

The control of the switching device for switching the direction of escape can alternatively or additionally be carried out via a further control device, which may be arranged for example in another door system. The control device of this door system may also include a switching device for switching the direction of escape and take over the role of a higher-level control device to ensure optimum interaction of several door systems.

Alternatively or additionally, a further control device, which automatically controls the switching device for switching the direction of escape, be arranged in a higher-level control center, for example in a building management center. In this building control center, measured variables and / or messages which indicate the presence of a dangerous situation can be collected and corresponding signals sent to the control device (s) of the sliding door system (s). be issued to trigger an emergency opening of the sliding door system (s) and / or a changeover of the escape direction (s).

In the following an embodiment in the drawing with reference to the figures will be explained in more detail.
