Description

The present invention relates to an access control system with at least one revolving door, in particular an access control system with at least one revolving door with an improved panic function and/or emergency function.

Access control systems are already known from the state of the art. Access control systems of this type can be found in many areas of application in which specially secured areas are to be accessible to people, but this access is to be controlled, e.g. in retail (particularly in the entrance and/or exit area and/or at the cash registers). Other areas of application include train stations, airports, ports, sports stadiums, sports halls, amusement parks, concert halls, office facilities, shopping centers or trade fairs. Access control systems are generally known in variously designed passageways that are closed by movable structures such as gates and the like.

Access control systems are usually configured to open when a person attempts to enter a restricted area (e.g. a shopping area) to allow an entrance, but remain closed when a person attempts to leave the restricted area through the entrance. This prevents people from leaving a restricted area (through the entrance) uncontrolled, thus preventing fraud and theft, for example.

An access control system with an emergency function enables people in an emergency and/or panic situation to escape from a restricted area in a more efficient manner through the access control system.

For example, the EP3571370A1 an automatic passage gate is known which has an emergency function. The passage gate is configured so that it can be driven in a first operating mode and a second operating mode (emergency mode). In the first operating mode, the passage gate in a first, open position allows people to pass through in a controlled manner. In a second, closed position, it prevents people from passing through the passage gate. In the second operating mode, a larger passage area is achieved than in the first operating mode. This enables a quick and safe evacuation from the passage area in an emergency.

The EP2458123A1 discloses an access control system or passage system with combined turning and sliding movement, which is intended to offer a high level of protection against accidents.

The WO2021013474A1 discloses an access control system with a pedestrian barrier comprising a locking element, wherein the locking element is pivotable about a vertical axis of rotation.

In addition, the KR20140147249A A gate system is known which has a combination of a rotatable opening and closing structure and a sliding opening and closing structure.

The CN209510204U reveals a swing gate device that opens quickly in an emergency.

It is the object of the present invention to further develop an access control system with at least one revolving door of the type mentioned above in an advantageous manner, in particular to the extent that handling in an emergency situation is facilitated and operational safety is increased.

This object is achieved according to the invention by an access control system with the features of claim 1. According to this, an access control system with at least one revolving door is provided, wherein the revolving door has a base frame and a pane that can be extended and retracted into and out of the base frame to allow access, wherein the base frame can be rotated about a vertical axis in the assembled state and wherein a panic function is implemented by means of at least one reset element in that the base frame can be brought from a basic position into a panic position in a panic situation by rotating and overcoming a panic resistance and an automatic reset can be implemented via at least one mechanical spring means of the reset element.

The invention is based on the basic idea that the revolving door can be automatically moved from the panic position back to the home position after the panic situation has ended, without manual resetting being necessary. This means that no personnel is required to return the access control system to normal operation, e.g. manually by hand, i.e. to move it from the panic position to the home position. This design makes the access control system according to the invention easier to handle, improves its reliability and overall increases its operational safety and its clear operating sequence. The panic resistance can be designed in such a way that a locking bolt is attached to the base frame, in particular in a floor area, which, when mounted, engages in at least one correspondingly arranged This at least one locking groove can be introduced, in particular in a base area, of a rotating column, wherein the rotating column defines the vertical axis about which the base frame can be rotated and/or pivoted in the assembled state.

A panic situation can be any type of emergency situation, such as a fire, heavy smoke, an attack, an alarm signal, a bomb threat, a mass panic, water entering a building, etc.

In particular, it can further be provided that the mechanical spring means is a gas pressure spring, in particular an adjustable gas pressure spring.

Gas pressure springs have the advantage that their spring characteristic is virtually independent of the spring travel due to their design as a pneumatic spring, so that large spring forces can be transmitted even with relatively small spring travels. Gas springs also have a high power density and therefore require little installation space. Furthermore, the gas pressure spring can have defined damping properties because its spring principle is based on a compressible gas. Since the mechanical spring medium, which can be designed as a gas pressure spring, can work together with the return mechanism, its damping properties ensure that the return mechanism is operated with little wear.

The return element can further comprise at least one rotary joint and at least one guide belt, wherein the rotary joint is connected to the mechanical spring means via the guide belt and the spring means can actuate the rotary joint via this.

By operating the swivel joint, which can act as a rotation interface between the base frame and the rotating column, the revolving door can be pivoted from the panic position back to the home position in response to the operation. The operation of the swivel joint via the mechanical spring means can bring about a temporary mechanical decoupling between the revolving door or base frame and the rotating column, so that an automatic pivoting back from the panic position to the home position can be achieved with less mechanical resistance. In this context, the belt can be attached to the mechanical spring means with its two ends. In the case of a spring element designed as a gas pressure spring, its two ends can be attached to the end of the gas pressure spring piston. Starting from the spring means, the belt extends through its two belt legs in the direction of the swivel joint, whereby the belt can wrap around the swivel joint circumferentially. Consequently, an actuation force generated by means of the spring element can be transmitted to the swivel joint. For axial guidance of the guide belt (relative to the vertical axis), the swivel joint can have two guide collars.

The revolving door can be designed to be lockable in at least one first position and in at least one second position.

The first position can be assigned to the basic position, and the at least second position can be assigned to a panic position. The locking can be formed in particular via the locking bolt. The locking provides a respectively defined and locally precise position for the revolving door in the basic position and in the panic position. The locking bolt can be guided axially displaceably in a bolt housing and can be adjusted by a bolt spring element (e.g. with an adjusting screw). The panic resistance can thus be set in a defined manner such that the revolving door can only be pivoted from the basic position when there is a resulting pressure force that pushes the locking bolt out of the locking groove. In particular, it can be provided that the rotating column has at least four of these locking grooves, each of which is offset by 90° relative to the vertical axis, so that the revolving door can be locked in a defined basic position and three panic positions defined relative to the basic position. The return element can have at least one helical leg spring. The mechanical spring means can be designed and set up in such a way that it interacts with the locking bolt and/or the reset element in such a way that a so-called breakout release of the locking bolt can be achieved after the panic situation has ended, so that the reset element can move the revolving door from the panic position to the basic position. The control impulse required for this release can be automatically transmitted to the mechanical spring means by a corresponding electrical or electromechanical release element or trigger element.

In particular, it can be provided that the revolving door, for example on the top or on the front, comprises a card reading device and/or card recognition device or chip reading device or chip recognition device. The card reading device and/or card recognition device or chip reading device or chip recognition device can make it possible for only persons who are equipped with a corresponding card or chip to be granted access via the revolving door. For this purpose, the card or chip can be connected to the card reading device and/or card recognition device. device or chip reader or chip recognition device or in their vicinity. Alternatively or additionally, it is conceivable that the function of the revolving door can only be set and/or changed by persons who have a corresponding card or chip.

Furthermore, it can be provided that a lighting device is incorporated into the revolving door, for example on the top or on the front, e.g. in the top of the basic frame. Such a lighting device makes it possible to show people who want to pass through the passage the correct direction to go, for example to an emergency exit or a collection point, in a panic situation (e.g. in the event of heavy smoke development or in the dark). A lighting device can, for example, comprise one or more LED lamps, lasers or similar.

Furthermore, it can be provided that the base frame of the revolving door is designed to be variable. In particular, the base frame of the revolving door can be designed to be variable in size (height and/or width). This has the advantage that the size (height and/or width) of the revolving door can be adapted, for example, to the size of the people and/or animals and/or objects that are to/wish to pass through the revolving door or are to be transported and/or to the height and/or width of the passage.

Furthermore, the access control system may comprise at least two revolving doors.

By providing two revolving doors, both can be swiveled into a panic position, so that the usable passage area through the access control system is virtually doubled. This means that in a panic situation, significantly more people can be led through the access control system compared to a single revolving door. In this respect, the operational reliability of the access control system can be significantly increased.

The at least two revolving doors can be assigned to a passage channel, whereby in the panic position the two revolving doors are placed parallel to each other in order to clear the passage channel.

By providing the pivoting revolving doors, both can be pivoted in parallel into the panic position, so that the passage area of the passage channel is not reduced by the width of the door. In other words, the revolving doors in the panic position maximize the passage area due to their parallel alignment, so that in a panic situation, significantly more people can be led through the access control system and the operational reliability of the access control system can be significantly increased.

1 shows a revolving door 12 of an access control system 10 according to the invention in front view.

The revolving door 12 has a base frame 14.

Furthermore, the revolving door 12 has a pane 16 that can be extended and retracted into the base frame 14.

In this embodiment, the access control system 10 is in normal operation.

Disc 16 is designed to allow access.

The disc 16 is axially displaceable, whereby in the extended state access is not permitted and in the retracted state access is permitted.

Not shown in 1 is that the base frame 14 of the revolving door 12, when the revolving door 12 is mounted in the access control system 10, is rotatable about a vertical axis.

Not shown in 1 is that the access control system 10 according to the invention comprises two revolving doors 12.

Alternatively, however, more than two revolving doors 12 may be provided.

Alternatively, only one revolving door 12 may be provided.

2 shows a plan view of the revolving door 12 according to 1 .

The revolving door 12 is mounted in the access control system 10 and can be rotated about a vertical axis.

In this embodiment, the access control system 10 is in a panic situation.

What is not explicitly shown is that the access control system 10 comprises two revolving doors 12, which are assigned to a passage channel.

Furthermore, it is not explicitly shown that in the panic position the two revolving doors 12 are positioned parallel to each other in order to clear the passage channel.

Not shown in 2 is that the revolving door 12 further comprises a return element 18, cf. 4b .

The return element 18 comprises at least one mechanical spring means 20, cf. 4b .

The reset element 18 is designed in such a way that it can implement a panic function.

The base frame 14 can be brought from a basic position into a panic position by rotating and overcoming a panic resistance.

An automatic reset can be realized via the at least one mechanical spring means 20 of the reset element 18.

In this embodiment, the mechanical spring means 20 is a gas pressure spring.

In particular, the mechanical spring means 20 in this embodiment is an adjustable gas pressure spring.

In this embodiment, the revolving door 12 can be rotated in both directions by up to 90° around the vertical axis. In other words: the revolving door 12 has a 180° panic function.

It is also conceivable that the revolving door 12 can rotate in both directions by up to 180° around the vertical axis.

Alternatively, it is possible for the revolving door 12 to be rotatable in both directions by up to 360° around the vertical axis.

3 shows a perspective view of the revolving door 12 according to 1 and 2 as well as details of panic resistance.

The revolving door 12 has a base frame 14, by means of which it can be rotated and/or pivoted about a vertical axis in the assembled state.

The vertical axis is defined by a rotating column around which the base frame 14 can be rotated and/or pivoted in the assembled state.

The panic resistance can be designed such that, in the assembled state, a locking bolt 28 is fastened to a floor area on the base frame 14, which can engage in at least one correspondingly arranged locking groove of the rotating column in the assembled state.

This at least one locking groove is in accordance with 3 in a circular plate-shaped base area of the rotating column.

Accordingly, according to the detailed illustration below, 3 the revolving door 12 can be locked in at least a first position and in at least a second position.

In this case, the first position can be assigned to the basic position, whereby at least the second position can be assigned to a panic position.

Consequently, the bottom portion of the rotary column has at least one first and at least one second locking groove, which according to 3 based on the positions of the “open” and “closed” positions in the floor area.

The locking is in accordance with 3 Furthermore, it is designed with a locking pin 28 which engages in the two locking grooves depending on the first or second position.

The locking bolt 28 has, as shown in detail in 3 a bolt housing in which the locking bolt 28 is guided axially displaceably relative to the bolt center axis.

The locking bolt 28 is further adjustable by a bolt spring element (e.g. a helical compression spring) (e.g. with an adjusting screw), so that the panic resistance already described above can be adjusted in a defined manner such that the revolving door 12 can only be pivoted from the basic position when a resulting tangential pressure force is applied, which presses the locking bolt 28 out of the locking groove.

Furthermore, the locking bolt 28 has two symmetrical angled bevels at its free end, whereby the angles of the bevels provide a further possibility of adjusting the panic resistance (the locking grooves have bevels with corresponding angles).

Furthermore, it can be provided that the rotary column has at least four of these locking grooves described above (not in 3 shown), which are each offset from each other by 90° with respect to the vertical axis, so that the revolving door 14 can be locked in a defined basic position and three panic positions defined with respect to the basic position by 90° or 180°.

Alternatively, it is also possible for two basic positions and two panic positions to be formed using these four locking grooves described above.

The return spring 26, which is also in 3 and which is one of several components of the return element 18 from 4b is, according to 3 a helical leg spring, which provides the required rotational energy to swing the revolving door 12 back from the panic position (“open”) to the basic position (“closed”).

The return spring 26 engages both in the rotary column and in the base frame 14.

4a shows a further perspective view of the revolving door 12 according to 1 to 3 and the detail A shown by the ellipse in the form of the return element 18.

4b shows a perspective view of a bottom part of the base frame 14 of the revolving door 12 according to 1 to 4a and a more detailed representation of the return element 18.

In this part of the base frame 14, the mechanical spring means 20, the swivel joint 22 and the guide belt 24 are accommodated, wherein the swivel joint 22 forms the bottom-side rotary interface between the base frame 14 and the rotary column.

The return element 18 in turn has the swivel joint 22 and the guide belt 24 (the return spring 26 and the locking bolt 28 from 3 are in 4b not shown).

The swivel joint 22 is connected to the mechanical spring means in the form of the gas pressure spring or gas tension spring 20 via the guide belt 24, whereby the spring means 20 can actuate the swivel joint 22.

The guide belt 24 is attached at both ends to the mechanical spring means 20.

In the case of 4b , in which the spring means 20 is designed as a gas pressure spring or gas tension spring, its two ends are attached to the end of the gas pressure spring piston or gas tension spring piston.

Starting from the spring means 20, the belt 24 extends through its two belt legs in the direction of the swivel joint 22, wherein the belt 24 partially wraps around the swivel joint 22 based on a defined wrap angle.

Consequently, an actuating force generated by the spring means 20 can be transmitted to the rotary joint 22.

For axial guidance of the guide belt 24 (relative to the vertical axis of the rotary column), the rotary joint 22 can have two guide collars.

The actuation of the rotary joint 22 via the mechanical spring means 20 can cause a temporary mechanical decoupling of the locking between the revolving door or base frame 12 and the rotary column (not in 4b shown), so that an automatic return from the panic position to the basic position can be realized with less mechanical resistance.

The mechanical spring means 20 is designed and arranged such that it at least partially interacts with the locking bolt 28 and/or the reset element 18 via the guide belt 24 such that after the end of the panic situation, a so-called breakout release of the locking bolt 28 can be realized, so that the reset element 18 can transfer the revolving door 12 from the panic position to the basic position.

The control impulse required for this release can be automatically generated by a corresponding electrical or electromechanical release element or trigger element (not included in 4b shown) to the mechanical spring means 20 in the form of the adjustable gas pressure spring.

By the above-described actuation of the rotary joint 22, which can act as a rotary interface between the base frame 14 of the revolving door 12 and the rotary column, the revolving door 12 can be automatically pivoted from the panic position back to the basic position in response to the actuation, without the need for a person to do so.

In addition, this type of swiveling can also be done by one person.

5a shows an access control system 10 according to the invention in a panic situation in perspective.

The access control system 10 comprises two revolving doors 12 according to 1 or 2 , each comprising a base frame 14 and a disc 16.

In this embodiment, the access control system 10 is in a panic situation, see. 2 .

In this embodiment, the disks 16 of the base frames 14 are each retracted into the corresponding base frame 14.

In this embodiment, both revolving doors 12 are rotated around the vertical axis.

The passage channel is thus opened.

5b shows the perspective view of a revolving door 12 according to. 1 or 2 with a lighting device 30.

In this embodiment, a lighting device 30 is incorporated into the upper side of the base frame 16 of the revolving door 12.
