Description

The present invention relates to an access control system having at least one rotating door, in particular an access control system having at least one rotating door with an improved panic function and / or emergency function.Access control systems are already known from the prior art. Access control systems of the present type are found in many fields of application in which specially secured areas are intended to be accessible to persons, but this access is intended to take place in a controlled manner, for example in retail retail retail outlets (in particular in the entry and / or exit areas and / or at the cash registers). Further areas of application include, inter alia, railway stations, airports, ports, sports stadia, sports halls, recreational parks, concert halls, office facilities, shopping centers or trades. Generally, access control systems are known in differently configured passageways which are closed by movable structures such as gates and the like.Access control systems are normally configured to open when a person wants to enter a delimited area (e.g. a shopping area) to enable entry. On the other hand, they remain closed when a person attempts to leave the delimited area through the entrance. In this way, persons are prevented from leaving a delimited area (through the entrance) in an uncontrolled manner, as a result of which fraud and theft are to be prevented, for example.An access control system with an emergency function enables persons in an emergency and / or panic situation to escape from a delimited area in a more efficient manner through the access control system.For example, EP3571370A1 discloses an automatic passage gate which has an emergency function. The pass-through gate is configured to be drivable in a first operating mode and a second operating mode (emergency mode). In the first mode of operation, the passageway gate in a first open position allows persons to pass under control. In a second, closed position, it prevents persons from passing through the passage gate. In the second operating mode, a larger pass-through range is achieved than in the first operating mode. This enables rapid and safe evacuation from the passage area in an emergency.EP2458123A1 discloses an access control system with combined rotational and sliding movement which is intended to provide a high level of protection against accidents.WO2021013474A1 discloses an access control system having a person lock comprising a locking element, wherein the locking element is pivotable about a vertical axis of rotation.Furthermore, from KR20140147249A a gate system is known which comprises a combination of a rotatable opening and closing structure and a sliding opening and closing structure.CN209510204U discloses a swing door device that opens rapidly in an emergency.It is the object of the present invention to advantageously develop an access control system having at least one rotating door of the type mentioned at the beginning, in particular to the effect 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 having the features of claim 1. According to this, an access control system having at least one rotating door is provided, wherein the rotating door has a base frame and a pane that can be extended and retracted into the base frame for releasing access, wherein the base frame in the mounted state is rotatably pivotable about a vertical axis and wherein a panic function is realized by means of at least one reset element in that the base frame and / or pane release access at least partially on account of actuation of the reset element.The invention is based on the basic idea of providing a simple construction for an access control system having a panic function.In particular, it can be provided 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 resetting can be realized by means of at least one mechanical spring means of the resetting element.This makes it possible, in particular, for the rotating door to be automatically transferable from the panic position back to the basic position after the panic situation has ended, without a manual resetting being necessary in the process. As a result, no personnel are required to return the access control system to normal operation, e.g. manually by hand, i.e. to transfer it from the panic position to the basic position. This embodiment facilitates the handling of the access control system according to the invention, improves its reliability and increases overall its operational reliability and its clear operational sequence. The panic resistor can be designed such that a latching bolt is fastened to the base frame, in particular in a base region, which in the mounted state can engage in at least one latching groove arranged correspondingly. This at least one latching groove can be introduced, in particular in a base region, 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 mounted state.A panic situation can be any kind of emergency situation, for example a fire, strong smoke development, a strike, an alarm signal, a threat of bombardment, a mass panic, water entry into 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 compression springs have the advantage that, due to their design as a pneumatic spring, their spring characteristic curve is virtually independent of the spring travel, so that large spring forces can be transmitted even with relatively small spring travel. In addition, gas springs have a high power density and therefore require little installation space. Furthermore, the gas pressure spring can have defined damping properties, since its spring principle is based on a compressible gas. Since the mechanical spring means, which can be designed as a gas pressure spring, can cooperate with the resetting mechanism, its damping properties are so-called for low-wear actuation of the resetting mechanism.The restoring element can furthermore have 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 thereby actuate the rotary joint.By actuating the pivot joint, which can function as a rotational interface between the base frame and the pivot column, the pivot door can be pivoted from the panic position back into the basic position in response to the actuation. The actuation of the pivot joint via the mechanical spring means can bring about a temporary mechanical decoupling between the rotating door or base frame and the rotating column, so that an automatic return pivoting from the panic position into the basic position can be realized with a lower mechanical resistance. In this context, the strap can be fastened with its two ends to the mechanical spring means. In the case of a spring element configured as a gas spring, its two ends can be fastened to the end of the gas spring piston. Starting from the spring means, the belt extends through its two belt legs in the direction of the pivot joint, wherein the belt can encircle the pivot joint circumferentially. Consequently, an actuating force generated by means of the spring element can be transmitted to the rotary joint. For axial guidance of the guide belt (with respect to the vertical axis), the swivel joint can have two guide collars.The rotating door can be designed to be latchable in at least one first position and in at least one second position.In this case, the first position can be assigned to the basic position, wherein the at least second position can be assigned to a panic position. The latching can be formed in particular via the latching bolt. By means of the latching, a respectively defined and locally precise position is provided for the rotating 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 adjusted in a defined manner such that the rotating door can only be pivoted from the basic position starting from a resulting compressive force, which presses the latching bolt out of the latching groove. In particular, it can be provided that the rotating column has at least four of these latching grooves, which are each offset relative to one another by 90° with respect to the vertical axis, so that the rotating door can be latched in a defined basic position and three panic positions defined with respect to the basic position. The restoring element can have at least one helical leg spring. The mechanical spring means can be designed and configured such that it interacts with the latching bolt and / or the resetting element in such a way that, after the panic situation has ended, a so-called breakout unlocking of the latching bolt can be realized, such that the resetting element can transfer the rotary door from the panic position into the basic position. The control pulse required for this unlocking can be automatically transmitted to the mechanical spring means by a corresponding electrical or electromechanical trigger element or trigger element.In particular, it can be provided that the rotating door comprises, for example on the top side or on the front side, a card reading device and / or card recognition device or chip reading device or chip reading recognition device. The card reading device and / or card recognition device or chip reading device or chip read recognition device may allow only persons equipped with a corresponding card or chip to access via the rotating door. For this purpose, the card or the chip can be held to the card reading device and / or card recognition device or chip reading device or chip reading recognition device or in the vicinity thereof. Alternatively or additionally, it is conceivable that the function of the rotating door can only be set and / or changed by persons who have a corresponding card or a corresponding chip.Furthermore, it can be provided that a lighting device is incorporated into the rotating door, for example on the top side or on the front side, e.g. in the top side of the basic structure. Such a lighting device makes it possible, in a panic situation (e.g. in the case of strong smoke development or in darkness), to indicate to persons wishing to pass through the passage the correct direction of travel, for example to an emergency exit or a collecting point. A lighting device may comprise, for example, one or more LED lamps, lasers or the like.Furthermore, it can be provided that the base frame of the rotating door is designed to be variable. In particular, the base frame of the rotating door can be designed to be variable in its size (height and / or width). This has the advantage that the size (height and / or width) of the rotating door is adapted to the size of the persons and / or animals and / or objects that are to pass / wish to be transported through the rotating door and / or to the height and / or width of the passage, for example.In addition, it can be provided that the access control system comprises at least two rotating doors.By providing two rotating doors, both can be pivoted into a panic position, so that the usable area of passage through the access control system is quasi doubled. Accordingly, in a panic situation, significantly more persons can be guided through the access control system compared to a single rotating door. In this respect, the operational reliability of the access control system can be significantly increased.The at least two rotating doors can be assigned to a through-channel, wherein in the panic position the two rotating doors are placed parallel to one another in order to release the through-channel.By providing the pivotable rotating doors, both can be pivotable parallel into the panic position, so that the area of passage of the passage channel is not reduced by the width of the door. In other words, the rotating doors maximize the area of passage in the panic position due to their parallel orientation, so that in a panic situation, significantly more persons can be guided through the access control system and the operational safety of the access control system can be further significantly increased.It is also conceivable for the reset element to comprise at least one panic button, by means of which the access control system can be actuated in such a way that the base frame and / or pane at least partially release the access.The panic button can unlock the access control system in such a way that the base frame and / or pane can be moved or moved, so that access through the access control system is enabled.The panic button may be an actuation element that is mounted on the access system in a well visible manner.A plurality of actuating elements can be provided, in particular at different points on the access system. This serves, for example, for the purpose that the actuating element or the panic button can be reached by persons of a wide variety of body sizes or statures.It is conceivable, for example, to attach this to the access system in a prominent and readily accessible manner, so that it can be easily actuated in an emergency.It is in particular conceivable for the panic button to allow a purely mechanical actuation and release of the base frame and / or pane. This is advantageous, for example, when scenarios in which a power failure is to be expected are to be covered.However, it is also possible for the panic button to trigger an electromechanical actuation and / or an electrical actuation and / or another suitable type of actuation, which causes the base frame and / or pane to at least partially release the access.Furthermore, it can be provided that the access control system has a rotational angle limitation.The angle of rotation limitation can be electromechanical or mechanical or purely electrical.The angle of rotation limitation is designed such that the base frame and / or pane can be pivoted only up to a predetermined angle. For example, angles in the range of up to 60% from the "zero position" are conceivable. This allows an optimized, lower swivel range to be achieved in panic mode.In addition, it can be provided that the access control system has a one-sided panic opening, in particular a one-sided panic opening with rotation restriction. One side of the access control system, i.e. one side with base frame and pane, can remain rigid, while the other side is opened in panic mode and allows access or passage through the access control system.Furthermore, it is conceivable that the access control system has at least one base element per base frame, which base element forms a raised floor. The original passage width can thus be obtained by the base element in the panic case and thereby further prevents e.g. the passage of large objects or the passage of larger logistics devices such as stackers and the like.In this connection, it is also conceivable that a pivotable post or a column is further integrated in the base element.In addition, it can be provided that the access control system has a panic sensor, by means of which a pane reset can be activated. In particular, in the case of a first triggering or actuation of the access control system or an intensified contact of the access control system by an angle sensor and / or a displacement sensor and / or an acceleration sensor and / or a force sensor and / or a contact sensor (or the like), a mechanical and / or motor-driven window pull-in can be activated. This can then allow passage. After a panic mode end, the pane can then be reset into the position for the operating mode.The panic mode can be terminated, for example, via a time limit or a button.It is furthermore conceivable that the access control system has at least one column anchored in the ground per base frame. It is conceivable, for example, for the access control system to have two base frames each with a pane and a column assigned to a base frame. The column is anchored in the ground. The column can be optically integrated in a recess of the base frame, for example, in the operating mode, i.e., it can be accommodated at least partially in the recess. The two columns result in three defined passage regions or zones for the panic mode. In the panic case, the flying persons are thereby distributed to three zones, which enables an improved guidance of escape movement. The passage of large objects or the passage of larger logistics devices such as stackers and the like is also prevented. For the column fastening to the floor, a quick-action clamping system (positive fit or the like) can be used. However, other types of fastening, such as a screw connection or a fixed inlet in the ground, are also conceivable.It is furthermore conceivable for the access control system to have at least one guide rail, by means of which at least one base frame can be moved in a guided manner.It is possible in particular for the guide rail to be partially L-shaped. The L-shaped rail allows it to be pushed on and then moved aside.Further details and advantages of the invention will now be explained with reference to an exemplary embodiment shown in more detail in the drawingsThe following are shown: FIG. 1 shows an exemplary embodiment of a rotating door of an access control system according to the invention in front view; FIG. 2 shows an exemplary embodiment according to the invention of a rotating door of an access control system in plan view; FIG. 3 shows a perspective illustration of the rotating door according to FIGS. 1 and 2 and details of the panic resistor; FIG. 4a is a further perspective view of the rotary door according to FIGS. 1 to 3; and; FIG. 4b shows a perspective illustration of a base-side part of a base frame of the rotating door according to FIGS. 1 to 4a and a more detailed illustration of a restoring element; FIG. 5 ashows an access control system according to the invention in a panic situation in a perspective illustration; FIG. 5 bshows a rotating door with an incorporated light signal; FIG. 5 cshows a rotating door with a variable base frame; FIG. 5d shows a rotating door with an integrated card reading device; FIG. 6 shows a further exemplary embodiment of an access control system according to.

FIG. 1, which has a sliding gate on the bottom side.FIG. 1 shows a rotating door 12 of an access control system 10 according to the invention in a front view.The access control system 10 can have in particular two rotating doors 12.The rotating door 12 has a base frame 14.The rotating door 12 also has a pane 16 which can be extended and retracted from and into the base frame 14.In this exemplary embodiment, the access control system 10 is in normal operation.The disc 16 is configured to release access.The disk 16 is axially displaceable, wherein in the extended state no access is released and in the retracted state the access is released.It is not shown in FIG. 1 that the base frame 14 of the rotating door 12 is pivotable about a vertical axis when the rotating door 12 is mounted in the access control system 10.It is not shown in FIG. 1 that the access control system 10 according to the invention comprises two rotating doors 12.Alternatively, however, more than two rotating doors 12 may be provided.Alternatively, only one rotating door 12 can be provided.FIG. 2 shows a top view of the rotating door 12 according to FIG. 1.The rotating door 12 is mounted in the access control system 10 and is pivotable about a vertical axis.In this exemplary embodiment, the access control system 10 is in a panic situation.It is not explicitly shown that the access control system 10 comprises two rotating doors 12 which are assigned to a through channel.Furthermore, it is not explicitly shown that in panic position the two rotating doors 12 are placed parallel to each other in order to clear the through channel.It is not shown in FIG. 2 that the rotating door 12 further comprises a restoring element 18, cf. FIG. 4 b.The restoring element 18 comprises at least one mechanical spring means 20, cf. FIG. 4 b.The reset element 18 is configured such that it can realize 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 resetting can be realized by means of the at least one mechanical spring means 20 of the resetting element 18.In this exemplary embodiment, the mechanical spring means 20 is a gas pressure spring.In particular, the mechanical spring means 20 in this exemplary embodiment is an adjustable gas pressure spring.In this embodiment, the rotating door 12 is rotatable in both directions by up to 90° about the vertical axis. In other words, the rotating door 12 has a 180° panic function.It is also conceivable for the rotary door 12 to be rotatable in both directions by up to 180° about the vertical axis.Alternatively, it is possible for the rotating door 12 to be rotatable in both directions by up to 360° about the vertical axis.FIG. 3 shows a perspective illustration of the rotating door 12 according to FIGS. 1 and 2 and details of the panic resistor.The rotating door 12 has a base frame 14, by means of which it is rotatable and / or pivotable about a vertical axis in the mounted state.The vertical axis is defined here by a pivot column about which the base frame 14 can be rotated and / or pivoted in the mounted state.The panic resistor can be designed such that in the mounted state a latching bolt 28 is fastened to the base frame 14 in a base region, which in the mounted state can engage in at least one latching groove of the rotating column arranged correspondingly.According to FIG. 3, this at least one latching groove is introduced into a circular-plate-shaped base region of the rotary column.Accordingly, according to the lower detailed illustration in FIG. 3, the rotating door 12 can be locked in at least one first position and in at least one second position.In this case, the first position can be assigned to the basic position, wherein the at least second position can be assigned to a panic position.Consequently, the base region of the rotary column has at least one first and at least one second latching groove, which, according to FIG. 3, are introduced in the base region on the basis of the positions of the "open" and "closed" positions.According to FIG. 3, the latching is furthermore formed by a latching bolt 28 which engages in the two latching grooves depending on the first or second position.According to the detailed illustration in FIG. 3, the latching bolt 28 has a bolt housing in which the latching bolt 28 is guided so as to be axially displaceable with respect to the bolt central axis.The latching bolt 28 is furthermore adjustable (for example with an adjusting screw) by a bolt spring element (for example a helical compression spring), so that the panic resistance already described above is thus adjustable in a defined manner such that the rotary door 12 can only be pivoted from the basic position starting from a tangential pressure force resulting therefrom, which presses the latching bolt 28 out of the latching groove.Furthermore, the latching bolt 28 has two symmetrically angled slopes at its free end, wherein the angles of the slopes provide a further possibility of setting the panic resistance (the latching grooves have slopes with corresponding angles).Furthermore, it can be provided that the rotating column has at least four of these latching grooves described above (not shown in FIG. 3 ), which are each offset relative to one another by 90° with respect to the vertical axis, so that the rotating door 14 can be latched by 90° or 180° in a defined basic position and three panic positions defined with respect to the basic position.Alternatively, it is also possible that these four latching grooves described above can form two basic positions and two panic positions.The restoring spring 26, which is also illustrated in FIG. 3 and which is one of a plurality of components of the restoring element 18 from FIG. 4 b, has a helical leg spring according to FIG. 3, as a result of which the required rotational energy is provided in order to pivot the rotary door 12 back from the panic position ("open") into the basic position ("closed").The restoring spring 26 engages both in the rotary column and in the base frame 14.FIG. 4 ashows a further perspective illustration of the rotating door 12 according to FIGS. 1 to 3 and the detail A illustrated by means of the ellipse in the form of the restoring element 18.FIG. 4 bshows a perspective illustration of a base-side part of the base frame 14 of the rotating door 12 according to FIGS. 1 to 4 aand a more detailed illustration of the restoring element 18.The mechanical spring means 20, the pivot joint 22 and the guide belt 24 are accommodated in this part of the base frame 14, wherein the pivot joint 22 forms the bottom-side rotational interface between the base frame 14 and the pivot column.The restoring element 18 in turn has the pivot joint 22 and the guide belt 24 (the restoring spring 26 and the latching bolt 28 from FIG. 3 are not illustrated in FIG. 4 b).The pivot joint 22 is connected via the guide belt 24 to the mechanical spring means in the form of the gas compression spring 20, wherein the spring means 20 can actuate the pivot joint 22 via this.The guide belt 24 is fastened at its two ends to the mechanical spring means 20.In the case according to FIG. 4 b, in which the spring means 20 is designed as a gas compression spring, its two ends are fastened to the end of the gas compression spring piston.Starting from the spring means 20, the belt 24 extends through its two belt legs in the direction of the pivot joint 22, wherein the belt 24 wraps around the pivot joint 22 partially circumferentially on the basis of a defined wrap angle.Consequently, an operating force generated by the spring means 20 can be transmitted to the pivot joint 22.For the axial guidance of the guide belt 24 (with respect to the vertical axis of the rotary column), the rotary joint 22 can have two guide collars.The actuation of the pivot joint 22 via the mechanical spring means 20 can bring about a temporary mechanical decoupling of the latching between the rotating door or base frame 12 and the rotating column (not shown in FIG. 4 b), so that an automatic return pivoting from the panic position into the basic position can be realized with a lower mechanical resistance.The mechanical spring means 20 is designed and configured such that it interacts at least partially with the latching bolt 28 and / or the restoring element 18 via the guide belt 24 in such a way that, after completion of the panic estimation, what is known as a breakout unlocking of the latching bolt 28 can be realized, such that the restoring element 18 can transfer the rotary door 12 from the panic position into the basic position.The control pulse necessary for this unlocking can be automatically transmitted by a corresponding electrical or electromechanical triggering element or trigger element (not shown in FIG. 4 b ) to the mechanical spring means 20 in the form of the adjustable gas pressure spring.By the above-described actuation of the pivot joint 22, which can function as a rotational interface between the base frame 14 of the rotating door 12 and the rotating column, the rotating door 12 can be automatically pivoted in response to the actuation from the panic position back into the basic position without a person being necessary for this purpose.In addition, this type of pivoting can also be possible by a person, however.FIG. 5 ashows an access control system 10 according to the invention in a panic situation in a perspective illustration.The access control system 10 here comprises two rotating doors 12 according to FIG. 1 or 2, each comprising a base frame 14 and a pane 16.In this exemplary embodiment, the access control system 10 is in a panic situation, cf. FIG. 2.In this exemplary embodiment, the panes 16 of the base frames 14 are each inserted into the corresponding base frame 14.In this embodiment, both rotating doors 12 are rotated about the vertical axis.The through channel is thus opened.FIG. 5 bshows the perspective illustration of a rotating door 12. FIG. 1 or 2 with a lighting device 30.In this exemplary embodiment, a lighting device 30 is incorporated into the upper side of the base frame 16 of the rotating door 12.In this exemplary embodiment, the lighting device 30 is a running light 30, which indicates in a panic situation in which direction the through channel is to be passed or left.FIG. 5 cshows a rotating door 12 according to. FIG. 1 or FIG. 2 with variable base frame 14.In this exemplary embodiment, the base frame 14 is designed to be flexible upwards and to the side.In other words, the height or side profile of the rotating door 12 may be made variable.FIG. 5 d shows a rotating door 12 according to. FIG. 1 or FIG. 2 with an integrated card reading device 32 in a perspective illustration.In this exemplary embodiment, a card reading device 32 is integrated into the base frame 14 of the rotating door 12, in particular into the upper side of the base frame 14 of the rotating door 12.The card reading device 32 permits the opening of the rotating door 12 when using a corresponding card.FIG. 6 shows an access control system 10 which comprises at least one panic button 34 as the reset element 18.The access control system 10 according to the exemplary embodiment according to FIG. 6 has here all structural and functional features such as the access control system 10 as described above and shown in FIGS. 1 to 5 d.Identical or comparable features are provided with identical reference numerals.However, the differences described below exist:The access control system 10 can be actuated by means of the panic button 34 in such a way that base frame 14 and / or pane 16 of the access control system 10 can be actuated, namely in such a way that they at least partially enable access. In the exemplary embodiment shown, the pane 16 can be retracted into the base frame 14 when the panic head 34 is actuated.The panic button 34 can unlock the access control system 10 such that base frame 14 and / or pane 16 become movable or are moved such that access through the access control system 10 is enabled.In the exemplary embodiment shown, a plurality of panic buttons 34 are provided.These are mounted in different places on the access system 10 in a readily visible manner. A panic button 34 is mounted on the top side of the base frame 14. Another panic button 34 is laterally attached. This serves to allow panic buttons 34 to be reached by persons of a wide variety of body sizes or statures.Panic button 34 may be formed in warning colors, e.g., with a housing in orange and a button element in red.It is conceivable in particular for the panic button 34 to allow purely mechanical actuation and release of the base frame and / or pane. This is advantageous, for example, when scenarios in which a power failure is to be expected are to be covered.However, it is also possible for the panic button 34 to enable electromechanical actuation (as in the exemplary embodiment shown) of only the panes 16, which then enable passage through the access control system 10.Alternatively, it is also possible for the panic button to trigger an electrical actuation and / or another suitable type of actuation, which causes the base frame and / or pane to at least partially release the access.FIG. 7 shows an access control system 10 with a rotation angle limitation 36.The access control system 10 according to the exemplary embodiment according to FIG. 7 has here all structural and functional features such as the access control system 10 as described above and shown in FIGS. 1 to 5 d.Identical or comparable features are provided with identical reference numerals.However, the differences described below exist:The rotational angle limitation 36 can be electromechanical or mechanical or purely electrical.The rotation angle limitation 36 in the exemplary embodiment shown is designed as an electromechanical rotation angle limitation 36 in such a way that the base frame and / or pane can be pivoted only up to a predetermined angle. For example, angles in the range of up to 60% from the "zero position" are conceivable. This allows an optimized, lower swivel range to be achieved in panic mode.It is shown in FIG. 7 that the angle of rotation limitation 36 causes the passage width d (indicated by the two parallel lines L that contact the end edge of the pane) to be limited.FIG. 8 shows an exemplary embodiment of an access control system having a one-sided panic opening 38 and a rotation angle limitation 36.The access control system 10 according to the exemplary embodiment according to FIG. 8 has here all structural and functional features such as the access control system 10 as described above and shown in FIGS. 1 to 5 dand FIG. 7.Identical or comparable features are provided with identical reference numerals.However, the differences described below exist:The one-sided panic opening is a one-sided panic opening 38 with a rotation boundary 36 (as shown in FIG. 7, but there on both wings or base frame 14).One side of the access control system 10, i.e. one side with base frame 14 and pane 16, can remain rigid, while the other side is opened in panic mode and allows access or passage (with the passage width d) through the access control system 10.FIGS. 9 aand 9 b show an exemplary embodiment of an access control system 10 which has at least one base element 40 for each base frame, which base element forms a floor elevation.FIG. 9 ashows the maximum movement possibility of the base frames 14 from above, FIG. 9 bshows the access control system 10 from the front.The access control system 10 according to the exemplary embodiment according to FIGS. 9 aand 9 b has here all structural and functional features such as the access control system 10 as described above and shown in FIGS. 1 to 5 d.Identical or comparable features are provided with identical reference numerals.However, the differences described below exist:Each base frame 14 is assigned a base element 40.The base elements 40 are anchored in the ground or fastened to the ground.The height of the base elements 40 is selected such that it is not easily possible to pass over.In the panic case, the base element 40 can be used to obtain the original passage width d and thereby further prevents e.g. the passage of large objects or the passage of larger logistics devices such as stackers and the like.FIGS. 10 aand 10 b show a further modification of the exemplary embodiment of the access control system 10 according to FIG. 9.FIG. 10 ashows the maximum movement possibility of the base frames 14 from above, FIG. 10 bshows the access control system 10 from the front.Here, it is shown that a pivotable post 42 or a column is furthermore integrated in the base element 40.The access control system 10 according to the exemplary embodiment according to FIG. 10 has here all structural and functional features such as the access control system 10 as described above and shown in FIGS. 1 to 5 dand in FIG. 9.Identical or comparable features are provided with identical reference numerals.However, the differences described below exist:The pivotable post 42 remains in the region of the base element 40 and cannot be pivoted out of the passage.The base frames 14 with the pane 16 retracted, however, are pivoted out of the way.FIG. 11 shows a further modification of the exemplary embodiment of the access control system 10.The access control system 10 according to the exemplary embodiment according to FIG. 11 has here all structural and functional features such as the access control system 10 as described above and shown in FIGS. 1 to 5 d.Identical or comparable features are provided with identical reference numerals.However, the differences described below exist:It is provided here that the access control system 10 has a panic sensor 44, by means of which a pane reset can be activated.In particular, in the case of an intensive contact, for example by counter-pressing or shaking, shown here as force F in the direction of the pane 16 of the access control system 10, a motor-driven pane retraction is activated by an acceleration sensor.In principle, it is conceivable that alternatively or additionally an angle sensor and / or a displacement sensor and / or a force sensor and / or a contact sensor (or the like) activates a mechanical and / or motor-driven window glass retraction. After a panic mode end, the pane 16 can then return to the position for the operating mode.The panic mode can be terminated, for example, by means of a time limit or a (separate) button.FIGS. 12 aand 12 b show a further modification of the exemplary embodiment of the access control system 10.Here, it is shown that the access control system 10 has at least one column 46 anchored in the ground per base frame 14.The access control system 10 according to the exemplary embodiment according to FIG. 12 has here all structural and functional features such as the access control system 10 as described above and shown in FIGS. 1 to 5 d.Identical or comparable features are provided with identical reference numerals.However, the differences described below exist:It is conceivable, for example, for the access control system 10 to have two base frames 14 each with a pane 16 and a column 46 assigned to a base frame 16. The two columns 46 are anchored in the ground. The column 46 can be optically integrated in a recess of the base frame, for example, in the operating mode, i.e., can be at least partially accommodated in the recess. The two columns 46 result in three defined passage regions or zones for the panic mode. In the panic case, the flying persons are thereby distributed to three zones, which enables an improved guidance of escape movement. The passage of large objects or the passage of larger logistics devices such as stackers and the like is also prevented. For the column fastening to the floor, a quick-action clamping system (positive fit or the like) can be used. However, other types of fastening, such as a screw connection or a fixed inlet in the ground, are also conceivable.FIG. 13 shows a further exemplary embodiment of an access control system 10.The access control system 10 according to the exemplary embodiment according to FIG. 13 has here all structural and functional features such as the access control system 10 as described above and shown in FIGS. 1 to 5 dand FIG. 11.In principle, the panic sensor 44, as shown in the exemplary embodiment, can also be dispensed with.Identical or comparable features are provided with identical reference numerals.However, the differences described below exist:It is provided here that the access control system 10 has at least one guide rail 48, by means of which at least one base frame 16 can be moved in a guided manner. It is possible in particular for the guide rail 48 to be partially L-shaped. The L-shaped rail 48 allows it to be pushed on and then moved aside.List of reference characters10 Access control system 12 Rotary door 14 Base frame 16 Pane 18 Restoring element 20 Spring means 22 Rotary joint 24 Guide belt 26 Restoring spring 28 Latching bolt 30 Lighting device, moving light 32 Card reading device 34 Panic button 36 Angle-of-rotation limitation 38 One-sided panic opening 40 Base element 42 Posts 44 Panic sensor 46 Column 48 Guide rail L Line F ForceReferences included in the specificationThis list of documents cited by the applicant has been produced in an automated manner and is only included for the better information of the reader.
