Description

The invention relates to a system for a door, in particular an emergency exit door or escape door, with a door lock that can be brought between normal operation and emergency operation, an unlocking device that can be attached to the door and has an actuating element, wherein when the actuating element is actuated, the Unlocking device can be brought from a position locking the door into a position releasing the door, in normal operation the door lock is in a locked state and an opening operation of the door is prevented despite actuation of the actuating element, in emergency operation the door lock is in an unlocked state and via a Actuation of the actuating element, an opening operation of the door can be carried out.

In the DE 10 2009 047 852 B4 describes a door guard who counteracts improper opening of an emergency exit door and at the same time ensures that the emergency exit door can be opened in an emergency. The door guard can be brought into three operating states, namely the monitoring state, pre-alarm state and alarm state. In the monitored state, the emergency exit door is closed and locked, and the door guard monitors whether an attempt is made to open the emergency exit door. The pre-alarm state is characterized in that the emergency exit door is still locked and locked and a sensor-perceptible pre-alarm is activated, for example acoustically and / or optically. The pre-alarm signals to the user that the door is an emergency exit door that is not intended for routine through traffic. This is intended in particular to open or misuse the

Emergency exit door can be prevented. If the user interrupts the opening attempt in the pre-alarm state, the door guard returns to the monitoring state. However, if the user continues to swivel the door monitor beyond the pre-alarm state, the door monitor switches from the pre-alarm to the alarm state. The emergency exit door can now be opened and is therefore accessible. However, this device known from the prior art has the disadvantage that it has increased structural requirements, which ultimately results in cost-intensive manufacture of these devices. This is due, among other things, to the fact that the device known from the prior art can be brought into three operating states, monitoring state, pre-alarm state and alarm state, which complicates the mode of operation.

The DE 100 64 956 A1 discloses an emergency button that is attached to a wall next to a door. A lock with a door handle is on the door.

The object of the present invention is to provide a system for a door which is functionally reliable, enables simple actuation of the door in an emergency operation, but is locked in normal operation, the invention simultaneously providing an inexpensive assembly.

To solve this problem, a system with all the features of claim 1 is proposed. Preferred further developments are set out in the dependent claims.

It is provided according to the invention that an externally accessible emergency button is integrated in the unlocking device and is in communication with the door lock in such a way that when the emergency button is activated, the door lock changes from normal operation to emergency operation. The essential essence of the invention is that the user only has to activate the emergency button in order to bring the door lock, which is usually in its locked state and thus locks the door, into the unlocked state. The door lock can be electrical, be electromechanical, electromagnetic. The door can only be opened by activating the actuating element of the unlocking device after the emergency button has been activated. If the actuating element is not actuated, the unlocking device is in its locking position, in which the door is locked. The locking position of the unlocking device is released when the actuating element is actuated, and at the same time the unlocking device assumes a releasing position in which the door can be opened. According to the present invention, it is not possible to trigger an emergency operation for unlocking the door lock simply by actuating the actuating element. Emergency operation can be achieved by pressing the emergency button. The user thus has two actions to take to get through the locked door in an emergency. The first action is the actuation of the emergency button and the second action is the actuation of the actuating element of the unlocking device. Surprisingly, it has been shown that a simple and compact component of the unlocking device with the actuating element and emergency button is created that is user-friendly to handle. The mechanics of the unlocking device can also be designed to be structurally simple and compact. There is no operative connection between the actuating element and the door lock, which means that the actuating element is decoupled from the self-locking door lock. Only the emergency button is in communication with the self-locking door lock, and in a preferred embodiment there can be an electrical and / or wired connection between the emergency button and the door lock. Of course, it is conceivable that in an alternative embodiment the emergency button can be connected to the self-locking door lock via a radio link.

It can also be provided that a further person-specific push button, which is accessible from the outside, is integrated in the unlocking device and is in communication with the door lock, in particular when the person-related button is activated, the door lock can be brought between the locked state and the unlocked state. The system can enable a limited number of people to intervene in the functionality of the system. By activating the personal button, the emergency mode can be deactivated or the normal operation of the self-locking door lock can be modified in such a way that the door lock is brought into the unlocked state. In defined applications, it may be desirable that the system according to the invention can be switched to a "deactivated mode". The “deactivated mode” is to be understood as an operating state of the locking system according to the invention in which the self-locking mechanism of the door locking is continuously and / or permanently prevented or the door locking is in a permanently unlocked state when the door is closed and the door is thus opened from both sides can be. Such a function is e.g. B. for doors in areas with relatively high passage frequencies, but also for doors with a day-night function, where access should be possible during the day and the door is locked at night. The deactivated mode can therefore be activated by activating it on the person-specific button.

Furthermore, it may be conceivable that an emergency state is present in emergency operation, in which an optical alarm and / or an acoustic alarm is emitted. The optical alarm can be emitted, for example, via a light element. The acoustic alarm can be transmitted via a loudspeaker. The light element can be designed such that the light element always emits light of at least one defined color, regardless of normal operation and emergency operation. It is also conceivable that light is only emitted via the light element in emergency operation. The light element can, for example Include OLEDs and / or LEDs. It is also conceivable that, in the alarm state, the light element emits flashes of light that are immediately recognized by the user.

The emergency mode can advantageously be reached when the emergency button is activated and / or when the person-related button is activated, the alarm state is absent, in particular when the door lock is in the unlocked state, the alarm state is absent. This is particularly advantageous if the user wants to temporarily gain access through the door via the person-related button without triggering an alarm state of the system.

According to the invention, the unlocking device has a housing on which the actuating element and the emergency button are arranged. In a possible embodiment of the invention, the person-related button and / or the door lock are arranged on the housing. This embodiment of the invention creates a compact system which can be easily installed on the door in a short time. It is also conceivable that the actuating element is located between the emergency button and the person-related button. This means that the actuating element is arranged in the center of the emergency button and the personal button. The emergency button and the person-related button are spaced apart, with the actuating element lying between them. In an alternative of the invention, it can be advantageous for the emergency button and the person-related button to lie next to one another or one above the other, whereby the emergency button and person-related button can be almost adjacent to one another. In the latter embodiment, the unlocking device can be further improved in its compactness. The unlocking device can advantageously have a locking element which is operatively connected to the actuating element. The locking element can, for. B. be designed as a trap and / or as a bolt. If the unlocking device is not actuated, the locking element is found in the blocking position, in which the door is blocked for opening. In addition, the door lock assumes its locked state, so that the door is blocked at two separate locations for opening or the door is locked at two locations.

It can also be designed that the door lock is monostable, so that the locked state is designed as a stable state. The monostable state can be canceled by activating the emergency button and / or the personal button.

In order to create a satisfactory handle for the user, the actuating element can be an essentially horizontally running pressure bar or panic bar, the emergency button and / or the person-related button essentially lying on an air line to the fastening element, in particular the actuating element being approximately in hand and / or chest and / or eye level is arranged on the door. When the pressure bar is activated, it is moved linearly and / or translationally on the door, at the same time addressing and moving a mechanism within the housing of the unlocking device that is operatively connected to the locking element. The same applies to the panic bar, which also interacts with a mechanism arranged inside the housing, which is simultaneously in operative connection with the locking element of the unlocking device. The panic bar can for example be pivotable about an axis on the door. The arrangement of the emergency button and / or the personal button essentially on the line to the actuating element increases the user-friendly operability.

In order to expand the applicability of the system, it can be provided that the door lock has a communication interface with which communication with a security unit can be carried out, with the security unit converting the door lock into normal operation and / or emergency operation is possible. The security unit can e.g. B. be part of a building security system that detects an emergency, such as fire, power failure, etc. The security unit can be connected to the system according to the invention, in particular to the door lock, via a wired line. It is also conceivable that the communication between the security unit and the door lock can take place via a radio link. Both of the alternatives mentioned last use at least one communication interface which is arranged in the door lock in order to ensure a satisfactory connection between the security unit and the door lock. The communication interface can also be used for the connection, in particular the signal connection with the emergency button and / or the personal button. For example, it is conceivable that the communication interface is a transmitting and / or receiving unit that communicates with transmitting and / or receiving units outside the door lock. The door lock of the system according to the invention can also be in communication with further door locks or with other systems according to the invention.

In order to increase the security and / or the functionality of the system according to the invention, a smoke detector and / or smoke detector can be arranged in the housing of the unlocking device, which is in operative connection and / or in communication with the door lock and / or with the security unit. A simple retrofit kit can thus be created, which can additionally detect smoke detection and trigger an emergency operation of the self-locking door lock via a corresponding signal which is sent to the door lock and / or the security unit.

It can also be provided that the door lock and / or the unlocking device has at least one energy store, in particular has at least two or three energy stores. The integration of at least one energy store within the housing of the unlocking device and for the door locking creates an autonomous system which can at least partially or entirely dispense with an external power supply.

It can also be provided that the door lock and / or the unlocking device, in particular the emergency button and / or the person-related button, can be operated by an external power supply.

The alarm state can preferably be deactivated by activating the personal button. The person-related button can be a key button and / or the person-related button can be a button that carries out an authentication query and / or the person-related button works without contact and / or the person-related button is a switch that can be operated manually. The authentication query can take place, for example, via nearfield communication and / or via an RFID sensor. The authentication query can advantageously be carried out codified. It can also be provided that the person-related button is designed in such a way that it works without contact, for example the person-related button can have a capacitance sensor that detects proximity of the user. An authentication query checks to what extent the user is the authorized person to activate the personal button. With positive authentication, the self-locking door lock can be switched from normal operation to emergency operation, or the person-specific button can deactivate or switch off an alarm state that was previously triggered. The person-related push button can also be designed as a piezo sensor, in particular a appropriate touch by the user is required. An authentication query, which can also be coded, is also conceivable here.

It is also conceivable that a sensor device is integrated within the housing of the unlocking device, which detects an activation of the actuating element and stores it, for example, and / or notifies the safety unit. In a further embodiment of the invention, the system can be connected to a hazard alarm system or fire alarm system (BMA) and / or a smoke and heat extraction system (RWA system) and / or to the fire service.

In Figure 1 a system for a door 1 is schematically shown, which has a self-locking door lock 10 and an unlocking device 20. The self-locking door lock 10 can be brought between normal operation and emergency operation. The door 1 is in the closed state, as in Figure 1 shown, the door lock is in normal operation. The normal operation of the self-locking door lock 10 means that the door lock 10 is in a locked state, so that the door 1 cannot be opened. Here, the door lock 10 is designed to be monostable, so that the locked state is designed as a stable state. In the present case, this means that when the door 1 is brought into the closed state from an open state, which is not explicitly shown, the door lock 10 is automatically brought into its locked state.

The door lock 10 has at least one movable locking element 12, which can be moved out of the door lock 10 as a function of normal operation or emergency operation (locked state) or can be drawn into the door lock 10 (unlocked state). In an emergency mode, the door lock 10 changes to the unlocked state. The emergency operation can be triggered, for example, by fire, fire, power failure, etc., so that the possibility is created within the system according to the invention that the door 1 is released for opening by the user.

The unlocking device 20 has an actuating element 28 which runs horizontally along the door leaf. The actuator 28 may, for. B. be designed as a pressure bar or panic bar, which are to be operated by the user in an emergency, as already described above. In an emergency or panic situation, the fleeing user can simply push or pivot the actuating element 28, so that the door 1 can be opened. The peculiarity of this system is that for the emergency situation of the user, first an emergency button 30, which in the Figures 2 to 10 is shown, to actuate the housing 22 of the unlocking device 20. The emergency button 30 is integrated within the housing 22 of the unlocking device 20 and is at the same time in communication with the door lock 10. This means that when the emergency button 30 is actuated, the unlocking device 20 switches from its normal operation to the emergency mode, and it switches to the unlocked state issues. The user can now move the unlocking device 20 from the position blocking the door 1 into a position releasing the door 1 by actuating the actuating element 28, the locking element 21 simultaneously moving out of the door frame 2 and moving into the retracted position within the unlocking device 20 . The door 1 can now be pivoted into an open position by the user.

As in the Figures 2 to 9 can be seen, the unlocking device 20 can be designed such that an externally accessible, person-specific button 40 is provided on the housing 22, which is only allows a certain group of people to operate the self-locking door lock 10. This means that the door lock 10 can be brought between the locked state and the unlocked state via the personal button 40. The personal button 40 can be a key button, a non-contact button or a manually operated button. It is also conceivable that when the personal button 40 is activated, there is a simultaneous authentication query between the user and the button 40. The button 40 can be connected wirelessly to the door lock 10. A wired connection between the two components 10, 40 is also conceivable.

In Figure 2 the actuating element 28 is located between the emergency button 30 and the person-related button 40. This exemplary embodiment has proven to be particularly user-friendly. In some applications, it may also be advantageous to arrange the emergency button 30 and the personal button 40 directly next to one another on the housing 22 of the unlocking device 20, which is shown in FIG Figure 3 is shown.

It can be provided that the system according to the invention, in particular the unlocking device 20 and / or the door lock 10, is designed with at least one energy store 11, 27 (see Figure 4 ). In addition, it can be provided that the door lock 10 and / or the unlocking device 20 are connected to an external power network. The energy store 11 can, for. B. be provided to drive the electric motor, which is not explicitly shown in the exemplary embodiments and which ensures the change between the locked state and the unlocked state of the self-locking door lock 10.

The energy store 27 within the housing 22 can, for example, be connected to the emergency button 30 and / or the person-related button 40 and supply them electrically. Both buttons 30, 40 can be supplied in normal operation as well as in emergency operation.

If there is an emergency operation, it is conceivable that the system according to the invention changes to an alarm state in which an optical alarm and / or an acoustic alarm can be emitted, which is shown schematically in FIG. The unlocking device 20 can have a light element 23 on the housing 22, which optically emits a corresponding alarm signal. Alternatively or additionally, a loudspeaker 24, which is integrated in the housing 22, can emit an acoustic signal.

In a further alternative, the housing 22 of the unlocking device 20 can have a smoke detector / smoke detector 25 which can detect an emergency, in particular can detect a fire in the vicinity of the system according to the invention. The smoke detector / smoke detector 25 is in operative connection or in communication with the door lock 10 or with a security unit 4 arranged inside the building. The self-locking door lock 10 can be switched to emergency operation on the basis of the signal transmitted by the smoke detector / smoke detector 25.

In Figure 7 is shown schematically that a sensor device 26 can be arranged inside the housing 22 of the unlocking device 20, which detects to what extent the actuating element 28 has actually been actuated by a user. The sensor device 26 can be in data communication with the unlocking device 20 and with the security unit 4.

Communication between the door lock 10, the unlocking device 20 and / or with the security unit 4 can be wireless, for example via radio. Here, the door lock 10, the unlocking device 20 have corresponding communication interfaces 3. The communication interfaces 3 can be transmitting and / or receiving units that can communicate with one another. It is also conceivable that there is a wired connection between the door lock 10, the unlocking device 20 and / or the security unit 4.

In Figure 9 it is shown that the door lock 10 can also be integrated within the housing 22 of the unlocking device 20. In this way, a particularly compact structural unit can be created, as a result of which the assembly outlay of the system according to the invention on the door 1 can be reduced.

At this point, it should be pointed out that all of the exemplary embodiments that are shown in Figure 2 to Figure 9 are shown, can of course be combined with each other.

The emergency button 30 according to all the exemplary embodiments can be designed as a touch button, proximity button, manually operated button or switch. The emergency button 30 can be designed with its own light element that can be easily recognized by the user. The color of the light element can vary depending on normal operation and emergency operation. The emergency button 30 can, for. B. be covered by a cover from the outside world. In order to actually activate the emergency button 30, it is necessary for the user to remove the cover, to pivot it, to push it away, etc., in order to access the emergency button 30 located below the cover. The cover is advantageously light-transparent so that the user reliably recognizes the emergency button 30 from the outside.

In a further alternative of the invention, which is not explicitly shown, it is conceivable that the person-related button 40 also has the locking cylinder of the door 1, which is used for locking and / or unlocking the door 1.

According to Figure 5 it is also conceivable that, alternatively or additionally, the door lock 10 has a loudspeaker 14 and / or a light element 15 in order to make the emergency operation recognizable for the user.

According to Figure 6 it is also conceivable that, alternatively and / or additionally, the door lock 10 is equipped with a smoke detector / smoke detector 13.

According to the embodiments Figure 2 to Figure 9 it is conceivable that all components within the door lock 10 and the unlocking device 20 can be connected to the security unit 4. The connection can be wired or wireless, for example via radio. For example, the communication interfaces 3 according to FIG Figure 8 ensure that there is a connection with the safety unit 4.
