Description

Safety device for securing a door in escape and

escape routes

The invention relates to a securing device for securing a door according to the features of the preamble of claim 1.

In practice, such security devices are used to secure a door in escape and rescue routes of buildings to secure doors in their closed position, in particular to lock and thus protect against burglary. At the same time, safety devices should make it easy and comfortable for the door to be accessed by an authorized person or in the event of an emergency. Especially in a panic case, it must be possible to safely open the door for anyone to escape from a building. EP 2 192 562 A1 shows such a security device.

From EP 1 473 431 A1 a door closing device for a fire door with a freewheel normal operation is known. It is a Door closer whose closing mechanism has an overrunning clutch to open the door during normal operation with the least possible use of force. For this purpose, the freewheeling function is switched on and uncouples the locking mechanism, so that the door can be opened and closed without being influenced by the door closer. This is an electrically actuated valve

provided, which influences a damper oil flow of the door closer. In the event of a fire alarm, the one-way clutch is automatically deactivated and thus the closing mechanism of the door closer becomes effective in order to automatically move the door into the closed position.

From DE 10 2010 022 049 A1 a door closer with free-running function is known. Also, this door closer can be used to protect fire doors, with a comfortable walking the door is made possible in normal operation on the freewheeling function, without having to work against the force of the door closer when opening the door. In case of fire, the door closer is automatically activated and spends the door in the closed position.

It is an object of the present invention to provide a security device for a door that can be used in escape and rescue routes and is also suitable for smoke protection or fire protection applications. Here, a high ease of use and at the same time a high level of security should be ensured.

In particular, the backup device should be compact and easy to assemble.

This object is achieved by a securing device with the features of claim 1. According to the invention it is provided that the securing device a

Locking device and a door closer with an electric

having switchable freewheel device, which is a power transmission of the

Closing spring on the linkage switchably prevents and / or releases at least in a closing direction and / or an opening direction. It further comprises a safety device, a control device which is connected to the switchable locking device and the switchable freewheel device and is designed so that it switches the locking device and the switchable freewheel device separately. The safety device thus has a door closer with electrically switchable freewheel device and additionally a switchable locking device, which has a

Control device can be switched separately. This makes it possible that the securing device not only safely spends a door in the event of a fire in the closed position, but also locks in the closed position. This achieves good fire protection or smoke protection. Nevertheless, one is

Emergency opening function provided, which allows the door in case of panic always safe to open and commit.

About the switchable freewheel device can be activated freewheel

Door leaves are manually operated without a counter force of the door closer. This means that to open and / or close the door no through a

Door closer increased resistance must be overcome. The door or the door can with activated freewheel device with relatively little

Force are moved. When the freewheel device is deactivated, the door closer acts in the closing direction on the door leaf in order to spend it in the closed position. Opening the door leaf is possible at any time with deactivated freewheel device against the force of the door closer. When opening the

Door leaf while the shutter spring of the door closer is charged. It is envisaged that the securing device for securing a door, preferably a fire door or escape door in escape and

Rescue routes can be used. It has at least one designed as a stop swing wing or rotary wing door, which is rotatably supported by bands on a fixed door frame. In addition, the securing device has a door closer, which is designed as a door drive and in a door closer housing or drive housing has a closing spring and a drive shaft which cooperates with a arranged between the door and the fixed frame of the door force-transmitting linkage, preferably Scherenarmgestänge or Gleitarmgestänge to pressurize the door in the direction of its closed position. Of the

Door drive of the door closer is designed as a spring drive. It has a closing spring acting on a door closer shaft. In particular, the door drive does not have an electric motor.

In order to be able to safely open the safety device in the event of an emergency or in the event of a panic, it is provided that in the region of the door a control panel or an RWS terminal, i. a rescue route security terminal with an emergency button

is arranged. Next, the securing device has a switchable

Locking device, which electrically locks the door in its closed position and / or unlocked. It is envisaged that in case of emergency or panic case via the RWS terminal or via the emergency button at any time

Unlocking the locking device and thus the door leaf

can be made. This ensures that the door can be opened safely at any time and can thus serve as a safe escape route. The advantage is that the control device with the switchable

Lock and the switchable freewheel device is connected and can switch both the locking device and the switchable freewheel device separately. This allows a universal use of the security device. The switching of the locking device and / or the

Freewheel device can be done for example by the

Control device has two different switching outputs. Depending on a switching output is connected to the locking device and the other switching output to the freewheel device. In particular, the control device, for example, in case of fire, the freewheel device for closing the door switch and / or in case of panic

Switch locking device to unlock the door leaf.

In particular, the safety device for escape doors and

Fire doors are used equally. It is not necessary to change the mechanical design or the electronic control. The control device can be configured so that it deactivates or switches off the freewheel device in a fire alarm or fire alarm to spend the door on the shutter spring in its closed position. Optionally, the control device can lock the door leaf in its closed position via the locking device.

In a panic alarm, the controller can the

Release the locking device and / or activate or switch on the freewheel device in order to hold the door leaf in an open position or to allow opening of the door leaf with little effort. It is advantageous that the securing device according to the invention enables a mechanical securing of a door, which serves as a fire door and escape route door of a building and at the same time ensures accessibility, since an opening of the secured door can be done with a relatively small amount of force.

In one embodiment, it can be provided that the control device has a bus interface and both the locking device and the freewheel device are connected to the control device via a bus system and the bus interface. It is intended that the

Control device via switching commands the locking device addressed directly and controls to lock and or unlock the door.

In one embodiment, it may be provided that the control device has a first input for connecting a smoke detector and / or

Fire detector and / or a fire alarm panel and / or a

Building control center and a second input for connecting the emergency button and / or the RWS terminal has. Thus, the controller has separate inputs, preferably the first input as

Fire alarm or fire alarm input is formed and the second input is designed as a panic or emergency alarm. One or more sensors or detectors can be connected to the inputs.

In one embodiment it can be provided that the control device is arranged in the RWS terminal, preferably in a space enclosed by a housing of the RWS terminal. Alternatively, it can also be provided that the control device within the Drive housing of the door closer arranged or mechanically fixed to the drive housing of the door closer.

A particularly simple installation results from the fact that the control device has a bus interface for a digital bus,

Preferably, CAN bus or LIN bus, and the emergency button and / or the RWS terminal and / or the switchable freewheel device and / or a smoke or fire alarm and / or a fire alarm panel and / or a

Building control center is connected via the bus interface with the control device or are. In particular, the bus interface can be designed as a serial bus interface, preferably designed as a bidirectional serial bus interface. The design of the bus interface as a serial bus interface results in a simple installation of the components, since they can be connected to the bus interface or the control device via a simple wire connection with two to four wires.

In one embodiment, it can also be provided that the

Control device and / or the locking device and / or the freewheel device and / or the door closer have a known per se TCP / IP protocol (Transmission Control Protocol / Internet Protocol), preferably implemented and communicates via the respective bus interface with a TCP / IP protocol or communicate. In particular, the control device and / or the locking device and / or the freewheel device and / or the door closer may be connected to the Internet. In particular, the control device and / or the

Locking device and / or the freewheel device and / or the

Door closer via the bus interface according to an IPv4 (Internet Protocol Version 4) and / or IPv6 (Internet Protocol Version 6) standard

communicate.

In particular, it is provided that the bus interface of

Control device and / or the locking device and / or the freewheel device and / or the door closer have a preferably adjustable IP address. Via the IP address, the respective bus interface and thus the respective component, i. H. the control device and / or the locking device and / or the freewheel device and / or the door closer are clearly identified in the network and thus addressed directly via the Internet. It is provided that the bus interface of the control device and / or the locking device and / or the freewheel device and / or the door closer each have or have an input device to manually enter or configure an IP address to the bus interface. It can also be provided to automatically assign the IP address generated, for example by DHCP protocol (Dynamic Host Configuration Protocol). The input device can also be designed as a web client to be operated via the bus interface. Preferably, the bus interface of the control device and / or the locking device and / or the freewheel device and / or the door closer can be designed as a client of a DHCP server.

In one embodiment, it may also be provided that the bus interface of the control device and / or the locking device and / or the freewheel device and / or the door closer is designed as a CANopen interface, that means the control device or at least individual components of the control device can via a CANopen bus be connected to each other. The CANopen communication protocol is standardized in the EN 50325-4 standard.

By connecting the control device and / or the

Locking device and / or the freewheel device and / or the

Door closer to the Internet, a particularly flexible control and or monitoring of the security device can be realized.

In particular, it can be provided that the control device is designed such that it deactivates or switches off the freewheel device when a connected smoke detector and / or fire alarm and / or a connected fire alarm panel and / or building control center sends a fire alarm to the control device, so that the door closer the Spaces the door in closed position. A further increase in the safety of the safety device is obtained by providing that the

Control device is connected to a closing position sensor or has a closing position sensor and is preferably designed so that it can open the door in case of fire after deactivating or switching off the

Freewheel device locked by the switchable locking device as soon as the door leaf has reached its closed position. This can be controlled in time or via the closing position sensor.

A safe use of the safety device in escape routes of a building is made possible by the fact that the control device is designed so that it controls the locking device for unlocking the door leaf when a connected emergency button or a

connected RWS terminal or a connected

Building control sends a panic alarm to the control device, so that the door leaf can be brought into an open position after a panic alarm. The panic alarm can either be from an emergency button mounted in the door area or from a remote location, such as a

Building control center come.

In particular, it can be provided that the control device is designed so that it switches on the freewheel device or leaves on when a connected emergency button or a connected RWS terminal or a connected building control center sends a panic alarm to the controller, so that the door without being acted upon by the Closing spring can be brought into an open position and / or the activated freewheel device holds the door in an open position. As a result, a facilitated opening of the door allows and thus also for disabled or children in case of danger, a simple walk the escape route allows. The door closer function is deactivated when the emergency button is pressed via the control device, so that the door can be opened without being forced by the door closer.

It can be provided that the activated freewheel device holds the door in an open position, so that the door or the door leaves after the first opening in the open position and the door is easily accessible by other escaping persons without the door must be opened or one of the opening counteracting force of the door closer must be overcome. Only when a fire alarm or a fire alarm is reported to the control device, a

Deactivation of the freewheel function, so that then the door is moved back into the closed position. This ensures that even in case of panic the function the door remains as a fire door and the door serves as a smoke seal.

In one embodiment, it is provided that the control device has an optical and / or acoustic alarm or is connected to such and is designed so that it emits an optical and / or audible alarm when a connected emergency button or a connected RWS terminal or a connected

Building control sends a panic alarm to the control device. As a result, the opening of the door can be reported, for example, in a locked room to prevent unnoticed opening of the door. Thus, the security device can also be used to secure escape routes in sensitive buildings, such as warehouses or department stores, as when opening the door on the alarm corresponding

Operating personnel are made aware of the opening of the door.

In one embodiment it can be provided that the control device has an input for connecting an authorization device or an access signal and is designed such that the

Control device upon receipt of an access signal or a

Authorization signals the locking device to unlock the door controls and turns on the freewheel device or leaves on and generates no optical and / or audible alarm or emits. Thus, it is possible to commit the door even without triggering an alarm, if an access authorization exists. The

Authorization device can be configured, for example, as a key switch or as a keypad, so that an authorized person with a key or, knowing the correct access code, can close the door without triggering an alarm.

It can further be provided that the control device has a

preferably adjustable timer and is adapted to receive the timer upon receipt of an access signal or a

Authorization signal triggers and after expiration of the timer the

Locking device for locking the door leaf controls. This ensures that after the door has been closed by an authorized person, the door is automatically moved back into the closed position or locked and thus the security device reliably secures the door even if the person in question forgets to manually arm the security device.

Furthermore, it can be provided in one embodiment that the

Control device has an input for connection of a motion detector which monitors the Begehungsbereich range of the door and the

Control device is designed so that it is the switchable

Free-wheeling device only switches off when the motion detector does not signal any movement. By means of the motion detector, the access area of the door can be monitored, so that the door is prevented from being closed by the door closer when there are still persons in the door

Stop the walk-in area of the door. The motion detector can as

Infrared detector or be designed as a radar detector and depending on the setting monitor the walk-in area or a certain safety zone before and after the access area of the door.

In one embodiment, it may be provided that the emergency button as

electromechanical emergency button or as arranged in the RWS terminal is formed touch-sensitive and / or displaceable mounted display. The electromechanical emergency button can be configured as a known emergency button, for example, as an emergency button with a red actuating mushroom, which locks after actuation, so that even after an operation is done, the triggering detector can be identified.

In an alternative embodiment, the emergency button can also as

touch-sensitive display, in particular touchscreen be formed and trigger a distress alarm or panic alarm when touching a marked as emergency button sensor surface and the control device

control accordingly. It is envisaged that the touch screen or the touch-sensitive display is arranged in a display-supporting housing of a control panel or RWS terminal, which in

Begehungsbereich the door is arranged. To an accidental

To prevent alarm triggering can be further provided that the

Control device is designed such that a touch of the

Touch-sensitive displays or touch screens first

Pre-alarm triggers and only after a certain period of time

Main alarm or panic alarm is generated. The pre-alarm may be configured as an audible and / or visual alert signal to alert an operator to the imminent main alarm.

In a further embodiment, the emergency button can also be designed as a displaceably mounted display, which is arranged in a housing of a RWS terminal. The sliding display can be used as

Touchscreen be configured to make switching inputs and / or send commands to the controller. To trigger a distress alarm, the display or the display surface is pressed by an operator and thus pushed into the housing of the RWS terminal to trigger a distress panic alarm. The displaceably mounted display can switch an electromechanical contact when moving. It may also be provided a position sensor which detects the position of the display and generates a panic or distress alarm when moving.

In order to enable intrinsically safe operation of the safety device, it can be provided that the switchable freewheel device releases the power transmission of the closing spring to the linkage in the de-energized state, and that the locking device unlocks the door leaf when de-energized.

In a structural design can be provided that the

Freewheel device has a switchable coupling element that is arranged between the drive shaft and the force-transmitting linkage to switch the drive shaft rotatably coupled to the linkage or disengage. The switchable coupling element can in particular be designed as an electrically switchable coupling element and, for example, comprise an electromagnet.

In a constructive embodiment can also be provided that the freewheel device comprises a switchable holding element, which is designed and / or arranged so that it is activated or

switched state prevents discharge of the shutter spring. The switchable holding element can, for example, as electrically switchable

Pawl or holding magnet be formed and cooperate with an output of the closing spring to hold this and / or to form a stop for this. In particular, it can be provided that the switchable Holding element is designed and / or arranged so that it allows in activated or on state, a charge of the closing spring, preferably a manual opening of the door leaf under charging the

Closing spring allows. Thus it is possible to open when opening the

Door leaf, the closing spring is loaded, without that after releasing the door leaf again discharging the closing spring. Advantageously, it can be provided that the freewheel device is a switchable

Holding element which is formed self-holding by putting it in

activated or on state prevents discharge of the shutter spring in any position, so that the switchable holding element in activated or on state allows manual opening of the door wing to charge the shutter spring and prevents closing of the door leaf under discharge of the shutter spring. As a result, virtually a continuous opening and holding function of the door leaf is made possible by the door manually by charging the shutter spring in a certain

Opening position can be spent and the holding element the

Closing spring automatically stops in this position. Will the door

subsequently moved back into the closed position, the closing spring remains in the charged position, so that the door leaf is movable up to this opening angle without influence of the opposing force of the door closer. If the door leaf is subsequently opened beyond this position, the closing spring is charged further without the need for a control intervention. Also in the renewed, this time further open position of the door leaf, the holding element holds the closing spring automatically, so that then a committing the door is made possible without the opposing force of the door closer. In order to achieve a comfortable opening operation of the door leaf, a door closer can be used, which when opening a sloping

Has opening moment. This ensures that even if the opening takes place against the force of the door closer, the door opening is comfortable by only by spending an increased force at the beginning of the opening process and against opening of the process, the opening force decreases.

In one embodiment, it can also be provided that the freewheel device has a switchable holding element which is designed and / or arranged such that it is in an activated or switched-on state for blocking the closing spring in a compressed or charged state

Position is formed and preferably detects the door in an open position. Thus, a determination of the door in a specific opening position can be made possible and thus, for example, for children or the disabled free passage of the door can be realized.

In a structural design can be provided that the

Closing spring is disposed within the drive housing in a filled with hydraulic fluid hydraulic chamber and the holding element is designed as an electrically switchable valve, which in an overflow channel of the

Door closer is arranged and prevents or releases a flow of hydraulic fluid out of the hydraulic chamber and / or into the hydraulic chamber. In particular, it can be provided that the electrically switchable valve in a blocked position prevents a flow of hydraulic fluid in one direction only and releases in the opposite direction and is arranged in an overflow that the electrically switchable valve prevents a discharge of the shutter spring in the on or blocked position and allows charging of the shutter spring. In another constructive embodiment can also be provided that the switchable holding element is designed as acting on the drive shaft brake element which is arranged so that it turns off a rotation of the drive shaft and turned on a rotation of the drive shaft blocked. The brake element may for example be designed as a friction brake, which prevents activated rotation of the drive shaft. Alternatively, the brake element may for example also be formed as a detent or pin which engages activated in a recess or toothing of the drive shaft to prevent rotation of the drive shaft.

Advantageously, it can be provided that the linkage with the

Drive shaft is connected via a driving device which rotatably coupled to the drive shaft in a rotational direction, preferably in the opening direction of the door, the linkage and allows in the opposite direction, preferably in the closing direction of the door, a separation of the rotationally fixed coupling between linkage and drive shaft. The

Carrier device forms, so to speak, a freewheel for the linkage and allows the door leaf is freely movable even when fixed locking device between a certain opening position on the locking device and the closed position.

In particular, it can be provided that the driver device rotatably connected to the drive shaft and rotatably connected to the linkage

Has drive plate with a stop, wherein the stop is arranged so that the stop comes in a manual opening of the door in contact with the linkage or an arm of the linkage and the drive plate or the drive shaft for loading the shutter spring entrains, and that in a driven closing of the door, the drive shaft rotates the drive plate in the closing direction until the stop comes into contact with the linkage or arm of the linkage and this entrains in the closing direction to spend the door in the closed position.

In one embodiment, the control device may be designed so that a permanent release of the door is possible. For example, via the RWS terminal or an authorization switch, in particular a

Key switch a permanent release be switched so that the door during the switching phase of the permanent release is freely accessible without restriction. Even during this permanent release, the safety against fire safety is ensured by the triggering of a fire alarm the

Control device off the freewheeling function and the

Door closer function activated.

Alternatively, via a timer, the duration release can also be configured as a short-term release by the release of the door when switching on

Control device activates a timer and automatically after closing the timer brings the door in the closed position and controls the locking device for locking the door leaf.

In the embodiment shown in Figures 1 to 6 of

Securing device 1 according to the invention is a

Embodiment of the security device according to the invention on a door in a building.

As can be seen from the illustration of Figure 1, the door 1 1 has a door leaf 12 which is rotatably mounted in a stationary frame 14 via bands 13 about a vertically extending axis of rotation A. The door leaf 12 is formed as a stop pivot wing. In the upper region of the door leaf 12, a door closer 2 is arranged, which is designed as Gleitarmtürschließer. The door closer 2 drives the door leaf 12 in the closing direction. On the wall next to the door 1 1, a RWS terminal 5 is mounted in the area next to the closing edge, which has a key switch 52 and an emergency button 51 for controlling the securing device. The door closer 2 is in the upper region of the door leaf 12 via a

Mounting plate 15 mounted overhead. 4, the door closer 2 of the securing device 1 is shown in sectional view. The Gleitarmtürschließer 2 has a drive housing or door closer housing 26 in which a drive shaft 21 is rotatably mounted. In the door closer housing 26 a filled with hydraulic fluid hydraulic chamber 25 is arranged, wherein in the

Hydraulic chamber 25, a door closer spring 23 is arranged. The

Door closer spring 23 cooperates with the drive shaft 21 via a piston and a cam gear. The drive shaft 21 is over a

Carrier 7 connected to the sliding arm 22. The free end of the slide arm 22 is guided over a designed as a roller or sliding block slider 28 in a slide rail 24 mounted on the door frame. The door closer 2 is designed as a mechanical or hydraulic door closer 2. Ie. the door closer 2 has no electric drive. He moves the door without external energy, so only based on the energy stored in the door closer spring 23.

As shown in Figures 1 and 3, together with the door closer 2 on the mounting plate 15, a resilient, so-called shooting latch 41 is mounted. The mounting plate 15 is thus formed as a common mounting plate 15 for the door closer and the latch. The lock latch 41 is part of the switchable locking device 4, which is shown in Fig. 3 in sectional view. The switchable locking device 4 has an escape door opener 42 mounted in the region of the slide rail, ie in the region of the door frame. The escape door opener 42 includes a trap receiving space into which the latch 41 engages in the closed position of the door. The trap receiving space of the escape door opener 42 is limited by a pivotable door opener trap which is electrically releasable and / or lockable. For switching on or locking the Vernegelungsvornchtung 4 this pivotable door latch latch is locked so that the door leaf 12 in its closed position on the

Locking device 4 is detected. To switch off or release the locking device, the door opener latch is unlocked so that it is pivotable about a parallel to the upper edge of the rotary wing 12 extending pivot axis, so that the lock latch 41 when opening the door leaf 12 can be brought out of engagement with the door opener latch.

In the figure 5 is an embodiment of the door closer 2 with a

Sectional view in the region of the solenoid valve 27 shown.

The door closer 2 has a switchable freewheel device 3, which comprises a switchable solenoid valve 27 as a holding element 31, which is arranged in the door closer housing 26 in an overflow channel of the hydraulic fluid. By switching on or activating the solenoid valve 27, the locking device is turned on and / or activated and prevented flow of the hydraulic fluid in the hydraulic channel in the direction corresponding to the closing direction of the door closer. The valve 27 is designed such that the flow of hydraulic fluid in only one

Direction prevents and allows in the opposite direction, ie in the opening direction. Thus, when switching on the valve 27 is achieved that the

Closing spring 23 can not discharge, since a flow of the

Hydraulic fluid is prevented in the hydraulic chamber 25 through the valve 27. If the door closer is switched on with valve 27 in

Opening sense pressed, so is a further charging or a

Compression of the closing spring possible because the switched valve 27 allows the outflow of hydraulic fluid from the hydraulic chamber 25 out. When the valve 27 is on the freewheel device 3 a

allows largely force-free operation of the door leaf 12 by the freewheel device comprises a driving device 7. This has a drive plate 71 with a fixed stop 72. The

Carrier 7 connects the sliding arm 22 with the drive shaft 21st The drive plate 71 is rotatably connected to the drive shaft 21. The sliding arm 22 is freely rotatably mounted on the drive plate. If the door closer 2 is actuated by opening the door leaf 12 in the opening direction, then the stop 72 comes into abutment with the sliding arm 22, so that the sliding arm 22 entrains the driver 72 while rotating the drive shaft 21 and thereby compresses the closing spring 23. When closing the door leaf 12 under the action of the door closer 2, the closing spring 23 discharges and thereby rotates the drive shaft 21 in the closing direction. The driver 72 in turn comes into abutment with the sliding arm 22 and takes it in the closing direction, so that the door leaf 12 is moved to its closed position.

When the holding element 31 or solenoid valve 27 is the

Door closer spring 23 is detected in its charged position so that it can not discharge and the output shaft 21 is not driven in the closing direction. By the driver 7, it is still possible to operate the door 12 in the closing direction by the sliding arm is moved in the closing direction and thereby stands out from the stop 72 and thus is freely rotatable. The door leaf can thus be moved without influence by the force of the door closer 2 between the detected opening position and the closed position. Now, if the door open wider than the previously set by the locking device locking position, the sliding arm 22 comes again into contact with the stop 72 and takes this under rotation of the Drive shaft 21 in the opening direction and under compression of the

Closing spring 23 with. The switched-on solenoid valve 27 allows in

Opening direction an escape of hydraulic fluid from the

Hydraulic chamber 25, so that the charging of the closer spring is easily possible. If closing of the door takes place again in the renewed further opening position, then this is again by the entrainment device 7 without

Force by the door closer allows.
