Description

[0001] The invention relates to a device for singling out persons in a singling out zone, comprising a stationary holding device, a rotary receptacle rotatable relative to the holding device in a rotational plane about a rotational axis, and at least two blocking beams, wherein the at least two blocking beams are received in respective blocking beam receptacles of the rotary receptacle corresponding to the respective blocking beam, such that upon rotation of the rotary receptacle in the rotational plane about the rotational axis, one of the blocking beams is pivoted out of the singling out zone and another of the blocking beams is pivoted into the singling out zone, thus enabling a person to be singulated from the persons upon passage through the singling out zone. The invention further relates to a person singling out device comprising a base body, a passage, and a device of the type mentioned.

[0002] Known devices for singling out people or also person singling systems are usually designed in such a way that a turnstile is mounted on an axis arranged at an angle in space and is designed to rotate about the corresponding axis. Such a turnstile has different barrier bars, which each swing in and out of a singling area when the turnstile is rotated. The arrangement of different barrier bars relative to one another is determined by the rigid design of corresponding turnstile systems, so that individual barrier bars not used in the singling area for singling out people, particularly in the foot area of a person walking through the turnstile, get in the way and hit their knees and / or shins, for example. In addition, bringing luggage, such as a backpack, through these rigid turnstile systems is correspondingly difficult.

[0003] Furthermore, turnstile systems are known in which, for example, as part of an emergency function or a service function, individual barrier bars can be released by means of a tool and swung out of the separation area.

[0004] DE 198 19 901 A1 describes a turnstile system for a pedestrian passage, in which the respective locking arms can be unlocked by means of a pin-shaped release for emergency release and can then be pivoted about an axis out of the separation area.

[0005] DE 20 2005 012 659 U1 discloses a turnstile. In the event of a power failure, the locking arms can be released in a rotating motion. The locking arms are spring-loaded and can be unlocked using a solenoid.

[0006] DE 27 58 971 A1 describes a turnstile in which a mechanical turnstile control has spring-loaded locking points and an additional anti-return device.

[0007] CH 646 755 A5 discloses a turnstile in which the respective locking bars can be mechanically unlocked and pivoted about an axis relative to a rotary holder.

[0008] EP 1 609 942 A1 relates to a turnstile with a single obliquely arranged barrier bar, which is rotated by 360° around a pivot point to separate people.

[0009] WO 97 / 18379 A1 discloses a turnstile with a single bar mounted on a rotating support on an inclined plane. Furthermore, a system for detecting authorized persons is described.

[0010] EP 3 239 451 also relates to a turnstile with two locking bars which are mounted at an angle to each other on a common rotating mount.

[0011] The object of the invention is to improve the state of the art.

[0012] The object is achieved by a device for isolating persons in a isolating area with a stationary mounting device, a rotary receiver which is rotatable relative to the mounting device in a rotational plane about a rotational axis, and at least two barrier beams, wherein the at least two barrier beams are received in respective barrier beam receivers of the rotary receiver corresponding to the respective barrier beam, so that when the rotary receiver is rotated in the rotational plane about the rotational axis, one of the barrier beams is pivoted out of the isolating area and another of the barrier beams is pivoted in the isolating area and thus a person can be separated from the persons when passing through the isolating area, wherein at least one of the barrier beams has a respective coupling device on the rotary receiver side,the at least one locking bar is movably received relative to the rotary receptacle in the respective locking bar receptacle, and the holding device has a control guide for guiding the respective coupling device, wherein the control guide mechanically corresponds to the respective coupling device and receives the respective coupling device, and the control guide imparts an additional movement to the respective coupling device upon rotation of the rotary receptacle, so that an additional movement relative to the rotary receptacle is imparted to the respective locking bar by means of the control guide and the respective locking bar is pivoted into the separation area with a delay and / or pivoted out of the separation area with an acceleration.

[0013] This arrangement makes it possible to design a device according to the invention such that the separation area is kept as clear as possible when the rotary mount is rotated, by pivoting corresponding barrier bars that are not directly used to separate a person as far as possible out of the separation area at this time. Depending on the design of the control guide and the respective coupling device, it can be achieved that only one of the barrier bars is arranged in the separation area, while other barrier bars not currently in use are pivoted completely out of the separation area.

[0014] The following terms are explained here:

[0015] A "person separation device" is a device that allows people in a separation zone to be separated from other people, for example, from a group of people. An example of such a device is a turnstile, which is located at a separation zone and, with corresponding barrier bars, serves to separate a particular person from a group. Such devices are also known as turnstile systems. Such a separation device can also be a retrofit device, for example, to supplement a passage or access to a corresponding functional area with a separation zone equipped with a corresponding device.

[0016] A "separation zone" is the area along, for example, a passageway or the passageway itself, in which the separation of people is physically carried out. For example, such a separation zone is located in a narrow passageway, so that the device for separating people extends into the passageway, thus transforming the passageway into a separation zone. For example, such a separation zone is an entrance to a swimming pool, an event, or a company or factory premises, so that the device for separating people regulates access to these very facilities.

[0017] A "holding device" is the component of the device for isolating people, which is mounted, for example, at a holding point, a wall, or a support, in order to align the device for isolating people in the correct position and at the correct angular orientation according to its intended function. "Stationarily mountable" describes that such a holding device is mounted, for example, using screws and dowels in a wall or a support column in such a way that a stationary position of the device for isolating people relative to the surroundings, for example, relative to the building structure, is achieved. For example, such a holding device is a base plate that rotatably accommodates a rotating support.

[0018] A "rotary mount" describes the component of the device for separating people that is rotatably mounted relative to the holding device, namely in a rotational plane around a rotational axis. Such a rotary mount also serves to accommodate corresponding locking bars and is, for example, a hub rotatably mounted on a base plate. A "rotational plane" is the plane in which the rotary mount rotates relative to the holding device. In contrast, the "rotational axis" is orthogonal to the rotational plane, so that the geometric allocation of the six degrees of freedom of the rotary mount is achieved by means of the rotational plane and the rotational axis. In practice, only a few of the six available degrees of freedom are used, for example, rotation around the rotary mount and, in particular, a corresponding, usually coupled, movement of one or more locking bars.The corresponding rotation plane and also the rotation axis are mathematically idealized and can exhibit technical deviations in both their alignment and straightness, so that, for example, a rotation axis is defined by the fact that the rotary mount can rotate around a bearing and thereby has a certain tolerance compared to the mathematically exact axis.

[0019] A "barrier beam" can be a rod-shaped or bow-shaped arrangement on the device for singling out people, which is mounted on the rotary mount. Typically, such a device for singling out people has two or more barrier beams; for example, a corresponding turnstile has three barrier beams. For correspondingly larger devices or correspondingly larger systems with such devices, four, five, or six barrier beams can also be provided. Such a barrier beam is formed, for example, from a tube or a round or other shaped, usually prismatic, base material. Such a barrier beam does not have to consist of a single strand, but can also be designed, for example, as a U-shaped bracket, in order to provide a larger projected area for a person to be singulated.

[0020] A "blocking beam holder" is, for example, a bearing or a differently designed holder for a respective blocking beam on the rotary holder, so that the blocking beam is arranged fixedly with respect to the rotary holder in some degrees of freedom by means of the blocking beam holder, but retains at least one degree of freedom, so that, for example, a respective blocking beam is designed to be rotatable or pivotable with respect to the rotary holder.

[0021] "Corresponding" describes that a corresponding end region of a barrier beam and a barrier beam receptacle assigned to the respective barrier beam are geometrically designed to match each other so that the barrier beam can be physically received in the barrier beam receptacle.

[0022] A "rotation" of the rotary holder describes the process in which the device for isolating people is put into operation, namely the rotary holder and thus also the corresponding locking bars are moved in a rotational manner around the rotation axis.

[0023] The process of one of the barrier beams being "swiped out" of the singling area and another of the barrier beams being "swiped in" into the singling area describes that a respective barrier beam is physically led out of the singling area and another of the barrier beams is physically introduced into the singling area, so that the respective barrier beam swung into the singling area serves to isolate a person, whereby a respective barrier beam swung out of the singling area, for example, clears another path for a person who has just been separated.

[0024] A person's "passage" describes the person's physical activity of moving through the isolation area or a physically existing passage, for example on foot.

[0025] A "coupling device" is, for example, a mechanical, in particular multi-part, device arranged in the extension of the respective barrier beam, which serves, for example, to mechanically couple the barrier beam to the holding device and to drive the barrier beams in such a way that a mechanically desired movement is transmitted to the respective barrier beam and / or initiated for the respective barrier beam.

[0026] "Movable" describes the fact that a respective locking bar retains at least one degree of freedom relative to the rotary holder, so that the locking bar can change its position and / or angular position relative to the rotary holder, in particular when the rotary holder is rotated.

[0027] A "control guide" is a guide associated with the holding device, which mechanically acts on the coupling device and can impart a corresponding movement to the coupling device and thus to the respective locking beam. Such a control guide is, for example, a slotted guide, a control groove, or another type of guide that performs its function, for example, via a positive locking mechanism.

[0028] The fact that the control guide "mechanically corresponds with the respective coupling device" describes, for example, that the control guide and the coupling device are coordinated with each other in such a way that, for example, there is a positive connection with a necessary play and / or a necessary tolerance, but this tolerance is set so tightly that the locking bar is guided with as little play as possible.

[0029] An "additional movement" describes a movement of the respective locking beam according to the degree of freedom still provided for the locking beam relative to the rotary mount, whereby this additional movement can be both translational and rotational and / or rotational in different axes.

[0030] If a respective barrier beam is pivoted into the separation area with a "delay", the movement of the respective barrier beam is changed by means of the additional movement in such a way that when the rotary holder is rotated, the respective barrier beam remains outside the separation area for a longer period of time with respect to and / or in relation to a full rotation of the rotary holder and only pivots into the separation area at a time when, for example, another barrier beam, by means of which a person has just been separated, is already pivoting out of the separation area.In contrast, the fact that the respective barrier beam is swung out of the singling area in an "accelerated" manner describes that the movement of the respective barrier beam is accelerated and / or increased in speed by means of the additional movement so that a corresponding barrier beam leaves the singling area as early as possible, for example as early as possible after a person has been singled, so that the singling area can be released as early as possible when the person leaves the singling area, for example, and can be used in the largest possible cross-section.

[0031] In order to be able to design the device for isolating persons as simply as possible and, for example, to equip the holding device with the necessary functionalities by means of known manufacturing processes, the control guide is embossed into the holding device, in particular essentially in the direction of the axis of rotation, in particular designed as a groove-shaped depression in the holding device and / or protruding from the holding device, in particular designed as a web-shaped projection from the holding device.

[0032] Thus, for example, if the holding device is manufactured as a cast component, a corresponding indentation, recess, or even a corresponding projection can be provided in a mold for the casting process. Likewise, when machining the holding device by means of machining, a corresponding groove-shaped recess can be milled, for example, or a corresponding projection can be produced by removing excess material. In this case, the control guide is arranged essentially in the direction of the rotation axis, thus further simplifying the machining of the holding device.

[0033] "Essentially in the direction of the axis of rotation" describes not only a direction which runs mathematically exactly along the axis of rotation, but also, for example, a technically induced deviation of in particular -10° to +10° or a desired deviation of, for example, -45° to +45°, so that, for example, by means of the corresponding angular alignment with respect to the axis of rotation, the control guide can be designed in such a way that it follows, for example, the additional movement of a corresponding locking beam without triggering tilting or mechanical blocking.

[0034] "Imprinted" describes a recess of the corresponding control guide relative to, for example, a surface of the holding device, so that the control guide is defined as a material removal and / or volume removal from the holding device, whereby a "groove-shaped depression" describes a concrete design of the control guide as, for example, a milled groove or pressed-in groove or control groove.

[0035] In contrast, "protruding" describes that such a protruding control guide has more material than, for example, a surface of the holding device, and therefore also more volume than the holding device.

[0036] A "web-shaped projection" is, for example, a concrete design of such a protruding control guide, which is designed, for example, as a web cast onto the holding device or as a web machined onto the holding device by means of milling.

[0037] In one embodiment, the control guide has a changing curvature along a control guide path, wherein the control guide is in particular assigned an auxiliary guide for supporting the guidance of the coupling device, the auxiliary guide is in supporting engagement with the coupling device at singularities, at curvature jumps and / or in regions of low curvature of the control guide path and guides the coupling device in a supporting manner.

[0038] By means of the changing curvature of the control guide along a control guide path, in cooperation with the respective coupling device of the respective locking bar, the respective locking bar can be mechanically influenced in such a way that an alternating additional movement is impressed on the respective locking bar around a full extent of rotation of the rotary holder, so that, for example, a respective locking bar is impressed with a respective additional movement in a respective angular position around the axis of rotation.

[0039] With such a changing curvature, movements or correlations between the coupling device and the control guide that tend to tilt or self-lock may occur, so that the coupling device can be guided accordingly by means of an auxiliary guide.

[0040] A "control guide path" describes the geometric progression of the control guide along, for example, a length of the control guide, whereby this control guide path is by no means straight, but is designed according to a changing curvature, so that, for example, a control guide has a meandering, heart-shaped or arched shape along certain areas of the control guide path.

[0041] A "varying curvature" describes precisely these different courses, which in any case do not have to be straight, but rather have, for example, straight areas, slightly curved areas, strongly curved areas and very strongly curved areas.

[0042] An "auxiliary guide" is, for example, a further depression or a further projection which is arranged at a distance from the control guide path and thus at a distance from the control guide, wherein the auxiliary guide is also designed mechanically to correspond to the coupling device and, for example, prevents tilting of the coupling device and thus tilting of the respective locking beam by, for example, a distance of the auxiliary guide from the control guide at a respective point serving as a lever arm in order to be able to apply a corresponding force against tilting.

[0043] "Supportive guidance" describes precisely this process, namely that the coupling device is "supported" in such a way that tilting in the control guidance at, for example, singularities, curvature jumps and / or in areas of low curvature is effectively prevented.

[0044] "Singularities" describe leaps or gaps in mathematical definition. For example, in a heart-shaped control guide, a strong curvature exists in the upper region of the imaginary heart, which then flows into a reversal point and merges into a second strong curvature arranged in a mirror image of the first strong curvature. For example, in a geometrically formed heart, an angular change of approximately 90° occurs. The point of the angular change describes the singularity, although the curvature of the guide is not clearly defined at this point. At such a singularity, corresponding disruptions to the mechanical movement of the coupling device in or on the control guide can occur, so that, for example, a respective locking bar could jam or the device itself could completely block.

[0045] Similar to such singularities, a "curvature jump" can lead to the same technical restrictions, namely when, for example, a weak curvature merges into a strong curvature and there is a transition that is continuous but not mathematically differentiable.

[0046] In contrast, a "low curvature area" describes an area of the control guide along the control guide path where the curvature is so slight that, for example, a locking bar and / or the respective coupling device can become jammed due to an undefined state of the coupling device to the control guide. In this case, it can also be said that the coupling device "tilts" in the control guide, so that no clear and unambiguous guidance is provided. In this case, the auxiliary guide serves to safely overcome such areas of the control guide, for example, when a low curvature is necessary for the desired additional movement of the respective control bar.

[0047] In order to securely yet movably receive the respective locking bar on the rotary mount, the locking bar mount has a joint for movably receiving the respective locking bar, wherein the joint is in particular a rotary joint, wherein a locking bar rotation axis is arranged substantially parallel to the rotation axis and / or the joint is a pivot joint, wherein a locking bar pivot axis is arranged substantially parallel to the rotation plane and / or substantially orthogonal to the rotation axis.

[0048] Such a joint ensures a mathematically correct and precise assignment of the respective locking bar to the rotary mount. A rotary joint serves to mount the locking bar so that it can rotate relative to the rotary mount, in particular parallel to the rotation axis. Thus, the respective locking bar can, for example, perform an additional movement such that a rotational movement, i.e., a rotary movement, is imparted to the locking bar parallel to the rotation axis.

[0049] In contrast, a pivot joint allows each locking beam to perform a pivoting movement about a locking beam pivot axis relative to the rotary mount as an additional movement, with the locking beam pivot axis being arranged substantially parallel to the plane of rotation and / or substantially orthogonal to the axis of rotation. Likewise, a coupled movement consisting of, for example, a locking beam rotational movement and a locking beam pivoting movement can also be performed if, for example, a joint with both mechanical degrees of freedom is used.

[0050] A "joint" is a mechanical connection in which, for example, one or more degrees of freedom are defined and released, while others are locked or blocked. Examples of such a joint include a hinge, a ball joint, or a swivel joint.

[0051] A "swivel joint" is a joint which, for example, enables a rotational movement of the barrier beam parallel to the axis of rotation, whereby the swivel joint can in particular also be designed as a functional unit with the respective barrier beam holder in the rotary holder, for example as a simple plain bearing.

[0052] A "bar beam rotation axis" describes the axis around which the bar beam is rotatably mounted relative to the rotary mount, whereby "essentially parallel" to the rotation axis describes that the bar beam rotation axis can have a technically necessary or technically caused deviation of, for example, -15° to +15° relative to the rotation axis, so "parallel" is not a mathematically precise term.

[0053] A "swivel joint" describes a joint that allows additional movement of the respective locking bar relative to the rotary mount in such a way that a degree of freedom is provided so that the respective locking bar can change its angle relative to the plane of rotation.

[0054] A "bar beam pivot axis" describes the joint axis of the pivot joint analogous to the bar beam rotation axis described above, but with a different reference axis.

[0055] In a further embodiment, the coupling device has a rotary coupling guide arranged eccentrically to the locking bar rotation axis, so that when the rotary holder is rotated and when the eccentrically arranged rotary coupling guide of the coupling device is guided in the control guide, an additional rotary movement about the locking bar rotation axis is imposed on the respective locking bar.

[0056] A coupling device designed in this way, in conjunction with the respective control guide, enables a defined guidance of the respective locking bar around the locking bar rotation axis, so that a reliable function of the device is ensured, particularly with this embodiment in conjunction with a rotary joint.

[0057] "Eccentric to the locking beam rotation axis" describes that the rotary coupling guide has a reference axis that is essentially parallel to the locking beam rotation axis, but spaced apart from it. Thus, a lever arm is created between the locking beam rotation axis and a corresponding reference axis of the rotary coupling guide. A movement of the reference axis relative to the locking beam rotation axis results in a rotary movement of the coupling device, enabling a rotary drive of the respective locking beam via the control guide, similar to a crank mechanism.

[0058] A "rotary coupling guide" is, for example, a pronounced end region of the coupling device, which serves as a drive lever relative to the locking beam rotation axis, so that a rotary coupling guide guided in the control guide triggers a rotation of the locking beam around the locking beam rotation axis.

[0059] In order to enable, in particular, an additional movement of the respective locking bar around the locking bar pivot axis in a technically reliable manner, the coupling device has an extension of the locking bar on the rotary support side, so that when the rotary support is rotated and when the extension of the coupling device on the rotary support side is guided in the control guide, an additional rotational movement around the locking bar pivot axis is imposed on the respective locking bar.

[0060] An "extension" of the barrier beam describes, for example, a pin, a shoulder or another mechanical extension of the respective barrier beam, whereby this extension is assigned to a side facing away from the rest of the barrier beam and in particular is located on an opposite side in relation to the barrier beam pivot axis opposite the barrier beam, so that a lever relationship arises between the extension and the barrier beam about the barrier beam pivot axis, i.e. a movement of the extension in one direction triggers a rotation of the barrier beam about the barrier beam pivot axis, whereby the barrier beam is moved in the other direction.The pin, the shoulder or the other mechanical extension can have additional means, for example for reducing friction and / or for reducing play, for example rollers, springs or spring-loaded rollers and / or combinations of these means, for example also with a corresponding roller guide.

[0061] In one embodiment, the barrier beam has a first barrier beam section and a second barrier beam section, wherein the first barrier beam section is received in the barrier beam receptacle and the second barrier beam section is designed to be offset relative to the first barrier beam section along a barrier beam longitudinal axis.

[0062] Such a cranked blocking beam enables further geometric adjustment of the movements of the device, so that, for example, a blocking beam that is rotatably mounted around the blocking beam rotation axis can be equipped with an additional crank and thus, by means of the rotary movement of the blocking beam around the blocking beam rotation axis, i.e. the additional rotary movement around the blocking beam rotation axis, a correspondingly delayed pivoting into the separation area and / or an accelerated pivoting out of the separation area can be additionally designed, namely by means of the geometry of the respective blocking beam itself.

[0063] In a further aspect, the object is achieved by a pedestrian isolation device comprising a base body, a passage, and a device according to one of the previously described embodiments, wherein the holding unit is mounted on the base body in such a way that, upon rotation of the rotary mount in the plane of rotation about the axis of rotation, one of the barrier beams is pivoted out of the passage and another of the barrier beams is pivoted into the passage, so that a isolation zone is formed in the passage. Such a pedestrian isolation device utilizes all the advantages of a device for isolating people, for example, by forming a complete pedestrian isolation device in the sense of a gate system and / or passage system.

[0064] A "person separation device" describes an entire system for separating people, which may, for example, include additional components or additional functional elements. Such a person separation device may have corresponding lateral barriers, such as walls, or other corresponding components of a gate system or even a fence system. For example, such a person separation device is a turnstile system used to regulate and restrict access to a factory premises.

[0065] A "base body" is, for example, a column, a wall or even a part of the system to which the holding device can be firmly, i.e. stationary, attached.

[0066] A "passage" describes the area in which the isolation of persons is to be carried out, namely in which the isolation area is located.

[0067] The arrangement of the holding device on the base body is selected such that corresponding locking bars interact with the passage in such a way that the separation area is arranged and formed in the passage, whereby, for example, the respective locking bars pivot into the passage or pivot out of the passage, depending on the rotation of the rotary holder in the rotation plane about the rotation axis.

[0068] In one embodiment, the rotation plane is arranged at an angle relative to a vertical plane, in particular at an angle of 20° to 70°, at an angle of 30° to 60° or at an angle of 45° relative to a vertical, wherein in particular the holding device is arranged on a fastening plane on the base body which is inclined according to the angle relative to the vertical plane.

[0069] An "angle" describes the angular relationship between the plane of rotation and a vertical plane, for example a vertical wall surface or a vertical, imaginary reference plane that runs parallel to a gravitational axis.

[0070] In order to functionally design the person separation device, a drive, in particular an electric drive, is assigned to the rotary holder, wherein the drive, in particular an electric drive, is controllable in particular by means of a control device for driving and / or locking the rotary holder about the axis of rotation.

[0071] The drive can be used to actively control and drive the rotary holder, so that, for example, the rotary holder can be blocked or locked if access is denied to a person to be separated, or the rotary holder can be driven if, for example, a person is to be guided through the separation area without resistance or with reduced resistance from a barrier bar.

[0072] The control device can also enable a so-called emergency function or evacuation function. For example, the control device controls the drive in such a way that, in such an emergency triggering an emergency function or an evacuation event triggering an evacuation function, free passage through the separation area is possible, for example, by allowing the rotary mount to remain freely rotatable or to be freely rotatable. Likewise, a corresponding locking bar can be unlocked by means of an actuator, for example, by releasing its pivot axis and / or another degree of freedom.

[0073] A "drive" describes an active mechanical intervention on the rotary mount, whereby, for example, a forced movement is imposed on the rotary mount so that a defined rotational behavior of the rotary mount can be achieved by means of the drive. Such a drive is typically electrical, for example, an electric motor or a brushless electric motor. Such a drive can also have a gear so that the speed or torque of the drive is or are reduced or increased.

[0074] A "control device" is, for example, a motor controller, a computer or a programmable logic controller, whereby the control device can receive and process electrical and / or electronic signals and convert them into signals for the drive in accordance with an instruction, in particular a software, previously stored in the control device.

[0075] For example, "driving" the rotary mount describes actively accelerating the rotary mount, resulting in increased movement of the rotary mount. In contrast, "locking" the rotary mount around the rotation axis describes a reduction of the corresponding rotation up to a complete blockage, i.e., a state of the rotary mount in which no rotational movement, especially no rotation, is possible. Such a "locking" occurs, for example, when a person passing through the pedestrian isolation device is to be denied access to an area monitored by the pedestrian isolation device.

[0076] In one embodiment, one, several, or all barrier beams have an indicator device for indicating a passage status. Such an indicator device can comprise lighting, a light-guiding device such as optical fibers or prisms, or even a reflection device such as reflectors, by means of which a light signal can be sent to a user. In the case of the reflection device or the light-guiding device, the necessary light source can be arranged outside the barrier beams, for example in a column. For example, each barrier beam is provided with an LED strip that can illuminate in different colors. For example, a green light indicates a free or released passage, a yellow light indicates that the person is waiting for permission, and a red light indicates a blocked passage, for example if identification has been rejected.Likewise, appropriate light can be directed and displayed to a user using reflectors on the barrier beams, light guides and / or prisms.

[0077] In a further embodiment, the rotary mount and / or one, multiple, or all of the beams are height-adjustable by means of a height-adjustment device, so that the height of the beams can be adjusted, for example, above a floor or above a reference plane. Thus, a height-adjustment device can be implemented in a simple form as a telescopic device for the rotary mount, which acts in the vertical direction. This telescopic device can be implemented, for example, in a height-adjustable column.

[0079] A turnstile system 101 is installed on a floor 103 near a wall 105. The turnstile system 101 has a column 107 that defines a passage 109 formed between the column 107 and the wall 105. The column 107 has a mounting surface 121 that is inclined by an angle 123 relative to a vertical. In the example shown, the angle 123 is an angle of 45°. The mounting surface 121 is inclined such that an upper region of the mounting surface 121 is closer to the wall 105 than a lower region, i.e., the mounting surface 121 is formed as an undercut in the column 107. The column 107 can be height-adjustable, for example, telescopic, for variably setting the height of a turnstile 111 in the passage 109.

[0080] The turnstile 111 is fixedly mounted on a mounting surface 121. For this purpose, a base plate 301 of the turnstile 111 is firmly screwed to the mounting surface 121. A hub 501 is rotatably mounted on the base plate 301, wherein the hub 501 carries several locking bars 203. In the example shown, three locking bars 203 are arranged evenly distributed around a circumference of the hub 501, in such a way that one locking bar 203 is arranged in the passage 109 and when the hub 501 is rotated relative to the base plate 301, another locking bar 203 is pivoted into the passage 109 and the locking bar 203 previously located in the passage 109 is pivoted out of the passage 109. By rotating the turnstile 111, persons can be separated in the passage 109 using the barrier bars 203.

[0081] Each barrier beam 203 has a round cross-section 281 and is provided with a locking section 204, a crank 205, and a pin 206 arranged on the section of the barrier beam 203 opposite the locking section 204. The cross-section of the barrier beams 203 is mentioned here as an example; oval, rectangular, or other shaped cross-sections can also be selected according to technical and / or aesthetic considerations. The barrier beams can also be interchangeable. A longitudinal axis 211 of the barrier beam 203 runs along the barrier beam and is provided with a change of direction around a bending point 207 and has a crank around the bending point 207 of approximately 45°. Thus, the longitudinal axis 211 runs completely along a longitudinal axis of the locking bar 203, in parallel to the locking section 204 and the pin 206. Furthermore, a groove 209 is provided on the pin 206, which serves for the rotationally fixed mounting of the locking bar 203.The locking beam is mounted with the pin 206 in the direction of the hub 501.

[0082] For this purpose, in the example described here, each barrier is equipped with an LED strip (not shown) that can illuminate in different colors. Such an LED strip can be optional, i.e., only present in certain alternatives. For example, a green light indicates a free or authorized passage through the turnstile system 101, a yellow light indicates, for example, waiting for clearance, or a red light indicates a blocked passage, for example, if identification has been rejected. Corresponding light can also be directed and displayed to a user using reflectors on the barriers, light guides, and / or prisms.

[0083] The holding plate 301 has a flange 305 on a rear side 303, wherein the flange 305 protrudes from the flat rear side 303 and is arranged concentrically to the round base plate 301. Mounting holes 307 are arranged in the flange 305, by means of which the base plate 301 is screwed to the column 107, namely by means of through-bolts (not shown). Alternatively, a welded connection or another connection can also be selected. Furthermore, a guide hole 309 is arranged concentrically in the base plate 301, which serves to accommodate the hub 501.

[0084] On a front side 311, which is opposite the rear side 303, the base plate 301 is geometrically designed to control the functions of the turnstile 111. For this purpose, the base plate 301 has a control groove 321, which is approximately heart-shaped and symmetrical to a central axis (along section AA in Figure 3c). The control groove 321 has a strongly curved region 323, a slightly curved region 325 and a tilting zone 327, wherein the control groove 321 has a singularity in the tilting zone, namely a jump in the (mathematical) differentiability, wherein the control groove 321 performs a change of direction of approximately 90°. The control groove 321 is embossed into the front side 311 of the base plate 301, namely as a milled control groove. Furthermore, the control groove 321 has a flat region 329, which is arranged along a course 341 of the control groove 321 opposite the tilting zone 327. This flat region 329 has almost no curvature, and is therefore very slightly curved compared to the strongly curved region 323 or the slightly curved region 325.

[0085] Furthermore, on the front side 311, namely protruding from the front side 311, there is an auxiliary guide 331 and an auxiliary guide 332 arranged symmetrically with respect to the central axis, which are arranged near the tilting zone 327. Along the flat area 329 there are an auxiliary guide 333 and an auxiliary guide 334, which are also designed as guides projecting from the front side 311. Each of the auxiliary guides facing the control groove 321 has corresponding guide surfaces, namely the auxiliary guide 331 has a guide surface 354, the auxiliary guide 332 has a guide surface 353, the auxiliary guide 333 has a guide surface 351, and the auxiliary guide 334 has a guide surface 352. These guide surfaces are arranged approximately perpendicular to the front side 311, i.e. in the direction of protrusion of the respective auxiliary guide.Furthermore, a fold 361 is formed circumferentially around the front side 311 on the round base plate 301.

[0086] A coupling piece 401 has a base body 403 to which a pin 405 is attached. The pin 405 has a web 461 on one end face, which is shaped to correspond to the groove 209 in the respective locking bar 203. This allows the locking bar 203 to be attached to the pin 405 of the coupling piece 401, for example, by means of a spot weld or an axial screw connection. For this purpose, the respective pin 206 of the respective locking bar 203 is placed onto the pin 405 along a rotation axis 481.

[0087] The coupling piece 401 further comprises a cross piece 411, which has an arm 413 with a head 414, an arm 415 with a head 416, and an arm 417. The arm 413 is arranged opposite the arm 415, and the arm 417 is arranged orthogonally to the arm 413 and the arm 415. The head 414 has a contact surface 451, and the head 416 has a contact surface 452. The arm 417 has a contact surface 453 and an opposite contact surface 454, with the respective contact surfaces being arranged laterally on the respective arms. The arm 417 further carries a pin 421 inserted into the arm 417 parallel to the rotation axis 481.

[0088] The hub 501 is also round and has a collar 561 on a rear side 503, which is geometrically designed such that the collar 561 engages over the fold 361 of the base plate 301 and thus ensures a smooth transition between the hub 501 and the base plate 301 without leaving a gap.

[0089] Furthermore, a shaft journal 531 is arranged concentrically on the rear side 503, which shaft journal engages in the guide bore 309 of the base plate 301 and is rotationally guided in the guide bore 309, wherein a fit is selected here which allows rotation of the hub 501 and reduces the tilting play of the hub 501 relative to the base plate 301 to a necessary minimum.

[0090] Within the shaft journal 531, a bore with a key 521 is inserted so that a torque from a drive (not shown) can be transmitted to the hub 501 via the key and the hub 501 is thus positioned relative to the base plate 301 which is firmly connected to the column 107.

[0091] Furthermore, the hub has three receiving bores 505 arranged symmetrically around a rotation axis 581, which correspond to the diameter of the pin 405 of the coupling piece 401. Thus, by means of the pin 405 of the coupling piece 401, a respective locking bar 203 can be rotatably received in the hub 501 around the rotation axis 481.

[0092] In a fully assembled state (compare Figure 6 ) the base plate 301 is firmly screwed to the column 107, three locking bars 203 are connected by means of the respective coupling pieces 401 (in Figure 6(each shown simply), wherein each coupling piece 401 is received in the corresponding receiving bore 505 of the hub 501 and thus each locking bar 203 is rotatable about the rotation axis 481 relative to the hub 501.

[0093] The hub 501, as a closing cover, is inserted with the shaft journal 531 into the guide bore 309 of the base plate 301 and secured relative to the base plate 301, for example, by means of a central screw connection (not shown). The respective pin 421 of the coupling piece 401 is received in the control groove 321 of the base plate 301, so that the pin 421 is guided by the control groove when the hub 501 is rotated relative to the base plate 301 by means of the drive. The assembly is held together by a screw 601 (only the screw axis is indicated).

[0094] If the hub 501 is now rotated relative to the base plate 301, the respective locking bar 203 is imparted an additional movement relative to the hub 501 by the coupling piece 401 and the guidance of the pin 421 in the control groove 321, whereby the additional movement depends on the geometric design of the control groove 321. In the present example, a locking bar 203 arranged in the passage 109 is held exactly horizontally and projecting widely relative to the hub 501 in the direction of the wall 105. In this state, the pin 421 of the respective locking beam 203 lies in the tilting zone 327 of the control groove 321. In order to prevent the coupling piece 401 from tilting at this point, the coupling piece is guided by the guide surfaces 453 and 454 in such a way that the contact surface 453 rests against the guide surface 354 and the contact surface 454 rests against the guide surface 353 and thus the coupling piece cannot tilt.

[0095] Upon further rotation of the hub 501, the pin 421 is initially held in the tilting zone 327, and the locking bar 203 undergoes an accelerated additional movement to the rotational movement of the hub 501, so that the locking bar 203 pivots out of the passage 109 at an accelerated rate. Subsequently, the pin is then guided through the strongly curved region 321 into the slightly curved region 325, whereby the accelerated movement is slowly converted back into a uniform movement to the rotational movement of the hub 501. If the pin 421 then dips into the slightly curved area 325 and is transferred into the flat area 329, there is a risk of the coupling piece 401 tilting relative to the base plate 301, wherein the coupling piece 401 is guided by means of the arms 413 and 415 and the contact surfaces 451 and 452 located thereon on the guide surfaces 351 and 352, so that no tilting of the coupling piece 401 is possible.In this area, the barrier beam 203 is guided as vertically as possible or essentially vertically, so that the then downwardly hanging barrier beam 203 is removed from the passage 109 for as long as possible. If the area opposite the control groove 321 just described is then transferred, an inverse process is carried out and by means of the pin 421, the coupling piece undergoes an additional movement, which enables a delayed pivoting of the barrier beam 203 into the passage 109. Thus, the passage 109 is passable for one person for as long as possible, and yet a safe separation of persons is possible by means of the barrier beam 203, which stands horizontally in the passage 109.

[0096] In an alternative embodiment, a turnstile system 701 comprises a turnstile 711, which is attached to a column 707 (only partially shown) and defines a passage 709 opposite a wall 705. The basic structure of the turnstile system 701 is analogous to the turnstile system 101, so only the different parts will be described. For this purpose, the turnstile system is equipped with the turnstile 711, which is fixedly mounted on a mounting surface 721 of the column 707. The column 707 can also be designed to be height-adjustable, for example, telescopic.

[0097] A base plate 801 is firmly screwed to the mounting surface 721. On a front side 811, the base plate has a control groove 821, which is embossed into the overall shape of the base plate. The control groove 821 is designed with round sections in the circumferential direction and partially flattened in the circumferential direction. For this purpose, the control groove 821 has respective regions 823 and respective regions 825, wherein the regions 823 are round and the regions 825 are flattened compared to the round regions. The shape of the control groove 821 follows a mathematical function that ensures a smooth transition, i.e., is continuous and, in particular, differentiable in the corresponding regions. This function can, for example, have sinusoidal sections, parabolic sections, or higher-order sections.The control groove is formed by means of a control ring 1101 placed on the base plate 801, but can alternatively also be formed as an integral part of the base plate, for example by milling.

[0098] A hub 901 arranged on the base plate 801, which is designed to be rotatable relative to the base plate 801 analogously to the hub 501 of the previous example, has on a front side 911 joint plates 921 which are arranged tangentially to a rotation axis 981. Two joint plates 921 each serve to form a pivot axis 923, wherein one of three locking bars 1001 is received on each pivot axis 923 by means of respective joint plates 921. The hub 901 further has a centrally and concentrically arranged, protruding pin 982, by means of which the hub 901, in an assembled state, is rotatably guided in a central and concentric bore 882 in the base plate 801 about an axis of rotation 881, which in the assembled state is arranged congruent with the axis of rotation 981.

[0099] Each locking bar 1001 has a locking section 1003, which can pivot into the passage 709, as well as a crank 1005 and a bore 1007, which serves as a pivot point for the respective locking bar 1001. Opposite the locking section 1003 in relation to the bore 1007, each locking bar 1001 has a coupling pin 1009, which in a normal state is arranged at an angle of approximately 45° to the locking section 1003. A longitudinal axis 1011 runs analogously to the longitudinal axis 211 of each locking bar 1001, cranked around the bore 1007, i.e., parallel to the locking section 1003 and to the coupling pin 1009. Each locking bar 1001 also has a round cross-section 1081. Each barrier beam 1001 is formed in two parts and has the locking section 1003 of the barrier beam 1001 with a connecting piece 1021 and a corresponding receiving piece 1041.

[0100] The connecting piece 1021 has a connecting flange 1023, which can be inserted into a slot 1043 of the receiving piece 1041. The common bore 1007 is thus formed in both the connecting piece 1021 and the receiving piece 1041, so that a bolt or an axis (not shown) connects both parts pivotably about the bore 1007. In the assembled state, the receiving piece 1041 is received in the region of openings 922 in the hub 901, so that in the assembled state, the arrangement of the bars 1001 with the locking section 1003 is received at an angle of approximately 45° to the hub 901 and thus to the base plate 801.

[0101] A bearing block 1301 with a base body 1303 and a circular groove 1307 is arranged on both sides of each bore 1007 of each receiving piece 1041 and stabilizes the bolt (not shown) located in the bore 1007 relative to the hub 901. Each bearing block 1301 is screwed to the hub 901 in order to fix the respective bearing block 1301 (not shown).

[0102] In an assembled state, the respective bore 1007 is aligned with the respective pivot axis 923, so that each locking beam 1001 is pivotally received in the hub 901. In the assembled state, each coupling pin 1009 is received in the control groove 821 by means of a roller 1201 slipped onto the coupling pin to reduce friction in the control groove 821, so that when the hub 901 rotates relative to the base plate 801, the locking beams 1001 are given a respective additional movement by means of the coupling pin 1009 guided in the control groove 821 by the roller 1201. Each roller 1201 is additionally provided with a spring (not shown) to compensate for play and prevent impact noises. Alternatively or additionally, a system comprising several springs or several springs in parallel can be used to achieve corresponding spring properties.Each barrier beam 1001 is guided in such a way that, analogous to the previous example, when the hub 901 is rotated, it is pivoted out of the passage 709 at an accelerated rate and re-enters the passage 709 at a delayed rate, so that a comfortable separation of persons is possible.

[0103] The function of a barrier beam 1001 in conjunction with the connecting piece 1021 and the connecting flange 1023 is explained in detail as follows:

[0104] As described, the connecting piece 1021 with its connecting flange 1023 is received in a slot 1043 in the receiving piece 1041 and is pivotably arranged about the common bore 1007. Furthermore, a lever 1401 is arranged in the receiving piece 1041 in a receptacle 1045, pivotably arranged about a bore 1047, such that a bore 1447 of the lever 1401 is aligned with the bore 1047 in the receiving piece 1041. Thus, the lever 1401 is pivotable about the bore 1047 of the receptacle 1045. For this purpose, a bolt (not shown) is inserted into the bore 1047 and into the bore 1447. The lever 1401 engages in a groove 1025 of the respective connecting flange 1023 and, when the lever 1401 is in engagement with the groove 1025, prevents the connecting flange 1023 and thus the connecting piece 1021 from pivoting relative to the receiving piece 1041.This is the normal operating state of the turnstile system 701, in which an angle of approximately 45° is set between each blocking section 1003 of the barrier beam 1001 and the base plate 801 as well as the hub 901. In this state, the turnstile system 701 functions effectively and serves to separate people by means of the individual barrier beams 1001.

[0105] A pin 1455 of a guide bracket 1451 is received in an opening 855 in the base plate 801, which is arranged axially parallel to the bore 882 and thus parallel to the pivot axis 881. The guide bracket 1451 also has a slide rail 1453 which runs approximately parallel to an end face of the base plate 801 and which is of wave-shaped design. This wave shape effectively prevents wedging or tilting, so that, particularly in the event of a technical failure, the system can continue to rotate and, in particular, an emergency release is still possible. When the hub 901 rotates relative to the base plate 801, the lever 1401 of each locking bar 1001 slides on the slide rail 1453, so that the slide rail 1453 represents a control cam for the lever 1401. At correspondingly protruding areas of the slide rail 1453, the lever 1401 is pivoted about the bore 1447 and thus disengaged from a respective groove 1025 on the connecting flange 1023.The respective barrier beam 1001, in particular the respective barrier section 1003, can then be pivoted out of the passage 709 of the turnstile system 701 by pivoting the barrier beam 1001 about the bore 1007. Overall, by pushing the guide bracket 1451 forward relative to the base plate 801, a so-called emergency release can be performed, thus deactivating the turnstile system 701, for example, in an evacuation situation.

[0106] A normal state 1501 with the lever 1401 arranged along a vertical 1503 and engaging with the groove 1025 (cf. Figure 15 ) and an emergency release state 1601 with lever 1401 rotated by an angle of rotation 1603 (cf. Figure 16 ) once again illustrate the two different states of turnstile system 701.
