DETAILED DESCRIPTION OF SPECIFIC EMBODIMENTS

[0110] FIGS. 1a to 1e show various schematic views of an embodiment of a barrier body arrangement 100 according to the present application. FIG. 1a shows a perspective view, FIG. 1b shows a front view, FIG. 1c shows a side view, FIG. 1d shows a rear view, and FIG. 1e shows a further side view of the barrier body arrangement 100.

[0111] The barrier body arrangement 100 serves for use as a physical barrier element in a passage barrier of an access control system. In the present case, the barrier body arrangement comprises two transparent barrier bodies 102, 104 and a transparent (optical) separation layer 106, which is arranged between the barrier bodies 102, 104. In particular, the barrier bodies 102, 104 and the separation layer 106 form a barrier body composite 108. In particular, the barrier bodies 102, 104 and the separation layer 106 are firmly respectively permanently connected to one another and thus form the barrier body composite 108.

[0112] Preferably, a barrier body 102, 104 may be formed of acrylic and/or polymer carbonate. In particular, the separation layer 106 may be a polymeric separation film 106. In particular, the separation film 106 may be coated on both sides with an optically transparent adhesive. In a simple manner, the barrier bodies 102, 104 may be joined together by the separation film 106 in order to form the barrier body composite 108.

[0113] As can be seen from the Figures, the first barrier body 102 and the second barrier body 104 are formed in a plate-shaped and disk-shaped manner, respectively. In particular, the two barrier bodies 102, 104 may be formed identically. The outline of the barrier bodies 102, 104 may be substantially rectangular (as shown, corners may be rounded, for example).

[0114] In the present case, the separation layer 106 is arranged between two flat sides (which lie inside the barrier body composite 108) of the barrier bodies 102, 104. The outline of the separation layer 106 may substantially correspond to the outline of the barrier bodies 102, 104.

[0115] A barrier body 102, 104 may have a length 122 between preferably 30 cm and 120 cm. The width 124 of a barrier body 102, 104 can preferably be between 20 cm and 80 cm. The thickness 126 of a barrier body 102, 104 is in particular between 3 and 20 mm, preferably between 4 and 10 mm. The separation layer 106 may preferably have a thickness 128 of between 0.05 and 10 mm, more preferably between 0.15 and 0.5 mm.

[0116] It shall be understood that in variants of the application, the barrier bodies may also have different dimensions, at least in part.

[0117] The barrier body arrangement 100 comprises a light source device 110, exemplified herein by two light source strips 110. In the shown preferred embodiment, the light source device 110 comprises a plurality of first light sources 112, in particular in the form of LEDs 112, and a plurality of second light sources 114, in particular in the form of LEDs 114.

[0118] The light source device 110 is configured to couple light into the first light coupling surface 116 of the first barrier body 102 and/or the second light coupling surface 118 of the second barrier body 104. In particular, the plurality of first light sources 112 are configured to couple light into the first light coupling surface 116 and the plurality of second light sources 114 are configured to couple light into the second light coupling surface 118.

[0119] The first light sources 112 may be configured to generate light in a first light wavelength range (e.g., 500 nm to 570 nm). The second light sources 114 may be configured to generate light in a second light wavelength range (e.g., 610 nm to 760 nm) that is in particular different from the first light wavelength range.

[0120] Preferably, the light source device 110 is arranged on a narrow side respectively an edge of the first and, in particular, also of the second barrier body 102, 104. In particular, this respective narrow side substantially forms the respective light coupling surface 116, 118. As shown, the light source device 110 may extend along the entire length 122 of the respective narrow side.

[0121] According to the application, a separation layer refractive index n.sub.TS of the separation layer 106 is at least smaller than a first barrier body refractive index n.sub.SK1 of the first barrier body 102 and a second barrier body refractive index n.sub.SK2 of the second barrier body 104. This achieves that the barrier body composite 108 is optically transparent, but at the same time an optical separation between the first barrier body 102 and the second barrier body 104 is provided by the interface layer 106. Thus, the separation layer 106 according to the application can prevent light coupled via the first light coupling surface 116 from entering into the second barrier body 104, and light coupled via the second light coupling surface 118 from entering into the first barrier body 102.

[0122] As indicated in FIGS. 1a to 1e, the respective coupled light may be visible to users of the passage barrier (only) at the further narrow sides 130, 132 respectively edges 130, 132 of the respective barrier body 102, 104. For example, (only) edge 130 may illuminate green (while the remaining area appears only transparent and not colored) and edge 132 may illuminate red (while the remaining area appears only transparent and not colored). In particular, for a user located in front of the front side (cf. FIG. 1b), only the first (e.g. green) illumination is visible, while for a user located in front of the rear side (cf. FIG. 1d), only the second (e.g. red) illumination is visible.

[0123] FIG. 2 shows a schematic (sectional) view of a further embodiment of a barrier body arrangement 200 according to the present application. In order to avoid repetitions, essentially only the differences from the embodiment according to FIGS. 1a to 1e are described below and otherwise reference is made to the previous explanations. FIG. 2 serves in particular to explain in further detail the operation of a barrier body arrangement 200 according to the present application.

[0124] A light source device 210 having at least one first light source 212 and at least one second light source 214 is arranged on a narrow side of the barrier body composite 208. The illustrated light source device 210 comprises an optically non-transparent encapsulation 240 respectively housing. In other words, light cannot pass through the encapsulation 240. For example, the encapsulation may be made of metal or another opaque material.

[0125] The encapsulation 240 is preferably arranged in such a way that the light 242, 244 generated by the light source device 210, in particular the light sources 212, 214 (indicated by the arrows), is coupled only into the first light coupling surface 216 and the second light coupling surface 218. In other words, the at least one light source 212, 214 is in the present case completely surrounded respectively encapsulated by the encapsulation 240 and the barrier bodies 202, 204, i.e. in particular the narrow sides 216, 218 of the barrier bodies 202, 204. As can be seen, the encapsulation 240 has a U-shaped cross-section for this purpose.

[0126] Further, an optically non-transparent source separation layer 246 made of an opaque material (e.g., metal) is arranged in the light source device 210 between the at least one first light source 212 and the at least one second light source 214. The source separation layer 246 extends from an inner wall of the encapsulation 240 to at least the first barrier body 202 and second barrier body 204, respectively. Preferably, one end of the source separation layer 246 may extend into an intermediate space 248 between the first barrier body 202 and the second barrier body 204. This end of the source separation layer 246 may preferably be immediately followed by the optically transparent separation layer 206.

[0127] In particular, the source separation layer 246 may be part of the encapsulation 240 and preferably made of the same material. A first partial encapsulation 250 and a second partial encapsulation 252 are provided by the source separation layer 240 in the present embodiment.

[0128] The at least one first light source 212 is arranged in particular (only) in the first partial encapsulation 250 and the at least one second light source 214 is arranged (only) in the second partial encapsulation 252. A partial encapsulation 250, 252 of the first light source 212 and second light source 214, respectively, has the particular effect that scattered light and total reflection by critical angle exceeding can be prevented to propagate into the respective other barrier body 202, 204.

[0129] In particular, optical focusing orthogonal to the surface of the light input surface 216, 218 may be provided by a respective partial encapsulation 250, 252. Optionally, the light source device may comprise, in particular, not shown focusing modules (e.g., lenses) in front of each light source to further focus the generated light.

[0130] As further indicated in FIG. 2 by the arrows (different arrows shall symbolize in particular light of different wavelengths), the respectively coupled light propagates (in particular due to the described focusing) essentially orthogonally to the light coupling surface 216, 218.

[0131] Due to the separation layer 206 according to the application, this light is reflected by the separation layer. Since the barrier body arrangement 200 is generally surrounded by air and the refractive index of the air is less than the first barrier body refractive index of the first barrier body 202 and the second barrier body refractive index of the second barrier body 204, light also does not emerge from the outer flat surfaces 254, 256 of the barrier body arrangement 208 and the respective barrier body 202, 204, respectively. The light is also reflected at these boundary surfaces 254, 256. This will be explained in more detail below with the aid of FIG. 3.

[0132] Presently, the light may emerge from the narrow edges opposite the light coupling surfaces 216, 218.

[0133] FIG. 3 shows schematic views of an extract of a barrier body arrangement 300 according to the present application with different angles of incidence of light.

[0134] On the left side of FIG. 3 a (border) case (incidence of light at the critical angle) is shown where the angle of incidence φ.sub.E of the light is equal to the critical angle φ.sub.G. As can be seen, this results in the angle of reflection being φ.sub.A=90°. On the right side of FIG. 3, the (normal) case (total internal reflection) is shown, where the angle of incidence φ.sub.E of the light is larger than the critical angle φ.sub.G. In this case, the light is reflected. In particular, the angle of reflection φ.sub.A is equal to the angle of incidence φ.sub.E. As has already been described, the light source device (in particular the encapsulation with the source separation layer) can focus the coupled light in such a way that the angle of incidence φ.sub.E of the light at the separation layer 306 is (always) larger than the critical angle φ.sub.G.

[0135] FIG. 4 shows a schematic view of a further embodiment of a barrier body arrangement 400 according to the present application. In order to avoid repetitions, the differences from the previous embodiments (in particular in comparison with the embodiment according to FIG. 2) are essentially described below and otherwise reference is made to the previous explanations.

[0136] The shown barrier body arrangement 400 comprises at least one light decoupling surface 460, 462 respectively diffusion surface 460, 462. Presently, each barrier body 402, 404 comprises at least one light decoupling surface 460, 462. As indicated in FIG. 4 by the arrows 464, 466, the light impinging on the inside of the light decoupling surface 460, 462 emerges from the barrier body 402, 404 through the light decoupling surface 460, 462, i.e. it is decoupled.

[0137] As can be seen, the light emerges from an outer flat side 454, 456 (which extends in particular substantially parallel to the light propagation direction) only at the at least one light decoupling surface 460, 462 of a barrier body 402, 404. Only in this area of the outer surface 454, 456 a reflection of the light propagating in the barrier body 402, 404 is prevented. In the remaining area of the outer surface 454, 456, the light continues to be reflected.

[0138] At the surface area 460, 462, the light propagating in the barrier body 402, 404 is absorbed and, in particular, diffusely emitted into the environment. The light decoupling surface 460, 462 may preferably be luminous in color and therefore perceived by a user as being luminous in color (e.g., green or red, as has been described previously).

[0139] In the present embodiment, the surface of the light decoupling surface 460, 462 may be rougher than the surface of the surrounding surface of the light decoupling surface 460, 462. Preferably, the average roughness Ra.sub.LA of the surface of the at least one light decoupling surface 460, 462 may be greater than the average roughness Rau of the surface of the surrounding surface of the light decoupling surface 460, 462. A production of the at least one light decoupling surface 460, 462 may be performed by sandblasting.

[0140] In particular, the light decoupling surface 460, 462 may be formed in the shape of a specific symbol (e.g., circle, rectangle, arrow, letter, number, etc.) by sandblasting (or the like).

[0141] FIGS. 5a to 5c show various views of a further embodiment of a barrier body arrangement 500 according to the present application. FIG. 5a shows a top view, FIG. 5b shows a front view and FIG. 5c shows a rear view of the barrier body arrangement 500. In order to avoid repetitions, essentially the differences from the previous embodiments are described below and otherwise reference is made to the previous explanations. For the sake of clarity, a light source device is not explicitly shown in these figures, but only the respective at least one light source is shown by arrows.

[0142] In particular, a barrier body composite 508 is shown in these Figures in the form of a stacked arrangement. In the present case, the optically transparent separation layer 506 is arranged between a first flat side of the first barrier body 502 and a second flat side of the second barrier body 504. In this stacked arrangement, the first barrier body 502 can form the front side (cf. FIG. 5b) and the second barrier body 504 can form the rear side (cf. FIG. 5c) in the intended operation of the passage barrier. Each barrier body 502, 504 comprises a light decoupling surface 560, 562 exemplarily in the form of a circle.

[0143] Preferably, the first light sources 512 can generate light with a different wavelength than the second light sources 514 (indicated by the different arrows and hatching). This allows that the front side and the rear side can be illuminated in different colors at the same time. In this case, essentially only the respective light decoupling surface 560, 562 is illuminated, while the remaining area appears colorless and transparent to a user.

[0144] FIGS. 6a to 6e show various views of a further embodiment of a barrier body arrangement 600 according to the present application. FIG. 6a shows a top view, FIG. 6b shows a front view of the barrier body arrangement 600 in a first illumination state, FIG. 6c shows a front view of the barrier body arrangement 600 in a second illumination state, FIG. 6d shows a rear view of the barrier body arrangement 600 in the first illumination state, and FIG. 6e shows a rear view of the barrier body arrangement 600 in the second illumination state. In order to avoid repetitions, essentially the differences to the previous embodiments are described below, and otherwise reference is made to the previous embodiments. For the sake of clarity, a light source device is not explicitly shown in these Figures, but only the respective at least one light source is shown by arrows.

[0145] As can be seen, the first optically transparent barrier body 602 is presently arranged adjacent to the second optically transparent barrier body 604. In this barrier body composite 608, the optically transparent separation layer 606 is arranged between two narrow sides of the plate-shaped barrier bodies 602, 604.

[0146] From the front view (cf. FIGS. 6b and 6c), it can be seen that the front side of the barrier body arrangement 600 is formed by the front flat sides 668, 670 of the two barrier bodies 602, 604. The rear side (cf. FIGS. 6d and 6e) of the barrier body arrangement 600 is formed by the two rear flat sides 672, 674 of the two barrier bodies 602, 604. Each flat side 668 to 674 has at least one light decoupling surface 660, 662, 676, 678. Exemplarily, two light decoupling surfaces 660, 678 are presently shaped as an arrow, while the other two are shaped as a circle.

[0147] Preferably, the first light sources 612 can generate light with a different wavelength than the second light sources 614 (indicated by the different arrows and hatchings). As a result, in the first illumination state (cf. FIGS. 6b and 6d), when in particular only the first light sources 612 are activated while the second light sources 614 are deactivated, the light decoupling surfaces 662 and 676 illuminate in a first color (e.g., red). In this illumination state, in particular, the other two light decoupling surfaces 660, 678 of the second barrier body 604 are not illuminated. The second barrier body appears completely colorless and transparent.

[0148] This can, for example, indicate a failure state of the passage barrier and, in particular, signal to a user that it is not (currently) possible to pass through the passage barrier. It can also signal to the user that the passage barrier is (still) in a blocking state because, for example, a check of an access authorization of the user is not (yet) positive.

[0149] In particular, in the second illumination state (cf. FIGS. 6c and 6e), only the second light sources 614 may be activated, while the first light sources 612 are deactivated. In this illumination state, the light decoupling surfaces 660 and 678 may be illuminated in a different color (e.g., green) than the first color. This may indicate, for example, a fault-free operating state of the passage barrier and, in particular, indicate to a user that passage of the passage barrier is (currently) possible. In addition, the passage barrier may be in a bidirectional passage state. It can also signal to the user that a check of his access authorization was positive and in particular that the passage barrier is now released.

[0150] FIGS. 7a to 7e show various views of a further embodiment of a barrier body arrangement 700 according to the present application. FIG. 7a shows a top sectional view, FIG. 7b shows a front view of the barrier body arrangement 700 in a first illumination state, FIG. 7c shows a front view of the barrier body arrangement 700 in a second illumination state, FIG. 7d shows a rear view of the barrier body arrangement 600 in the first illumination state, and FIG. 7e shows a rear view of the barrier body arrangement 700 in the second illumination state. In order to avoid repetitions, essentially the differences to the previous embodiments are described below and otherwise reference is made to the previous embodiments. For the sake of clarity, a light source device is not explicitly shown in these Figures, but only the respective at least one light source is shown by arrows.

[0151] In particular, FIGS. 7a to 7e illustrate an interleaved barrier body arrangement 700. In the present embodiment, three separation layers 706.1 to 706.3 respectively separation layer regions 706.1 to 706.3 (wherein the separation layer regions 706.1 to 706.3 may be formed integrally) are arranged between narrow sides of the first barrier body 702 and the second barrier body 704, as an example. In particular, a recess 780 is provided in the first barrier body 704. The outline of the second barrier body 704 corresponds to the recess of the first barrier body 702. In particular, the second barrier body 704 can be inserted into the recess of the first barrier body 702 to form the barrier body composite 708.

[0152] From the front view (cf. FIGS. 7b and 7c), it can be seen that the front side of the barrier body arrangement 700 is formed by the two front flat sides 768, 770 of the two barrier bodies 702, 704. The rear side (cf. FIGS. 7d and 7e) of the barrier body arrangement 700 is formed by the two rear flat sides 772, 774 of the two barrier bodies 702, 704. Each flat side 768 to 774 has at least one light decoupling surface 760, 762, 776, 778. Exemplarily, in the present case, two light decoupling surfaces 760, 778 are shaped as an arrow, while the other two are shaped as a circle.

[0153] Preferably, the first light sources 712 can generate light with a different wavelength than the second light sources 714 (indicated by the different arrows and hatchings). As a result, in the first illumination state, when in particular only the first light sources 712 are activated while the second light sources 714 are deactivated, the light decoupling surfaces 760 and 778 illuminate in a first color (e.g., green). In this state, in particular, the other two light decoupling surfaces 760, 778 of the second barrier body 704 are not illuminated. The second barrier body 704 appears completely colorless and transparent.

[0154] This can, for example, indicate a fault-free operating state of the passage barrier and, in particular, signal to a user that it is (currently) possible to pass through the passage barrier. In addition, the passage barrier may be in a bidirectional passage state. It can also signal to the user that a check of his access authorization was positive and, in particular, that the passage barrier is released.

[0155] In particular, in the second illumination state, only the second light sources 714 may be activated, while the first light sources 712 are deactivated. In this illumination state, the light decoupling surfaces 762 and 776 may illuminate in a different color (e.g., red) than the first color. This may, for example, indicate a failure state of the passage barrier and, in particular, signal to a user that passage of the passage barrier is (currently) not possible. It can also signal to the user that the passage barrier is (still) in a blocking state, for example because a check of an access authorization of the user is not (yet) positive.

[0156] FIG. 8 shows a schematic view of a further embodiment of a barrier body arrangement 800 according to the present application. In order to avoid repetitions, the differences to the previous embodiments (in particular in comparison to the embodiment according to FIG. 4) are essentially described below and otherwise reference is made to the previous explanations.

[0157] In addition to the at least one first light source 812 and the at least one second light source 814, the light source device 810 comprises at least one third light source 882 and at least one fourth light source 884. The at least one first light source 812 and the at least one third light source 882 are in particular integrated in a first partial encapsulation 850. The at least one second light source 814 and the at least one fourth light source 884 are in particular integrated in a second partial encapsulation 852.

[0158] By means of a communication connection 886, the light sources 812, 814, 882, 884 can be controlled, in particular activated and deactivated. Optionally, the brightness can be changed.

[0159] The at least one third light source 882 is presently configured to generate light in a third light wavelength range that differs in particular from the first light wavelength range of the first light source. This makes it possible to illuminate the first barrier body 802 with two different colors (e.g., red and green).

[0160] In particular, the first and third light sources 812, 882 may be controllable such that either only the at least one first light source 812 is activated (while the at least one third light source 882 is deactivated) or only the at least one third light source 882 is activated (while the at least one first light source 812 is deactivated).

[0161] The at least one fourth light source 884 is presently configured to generate light in a fourth light wavelength range that differs in particular from the second light wavelength range of the second light source 814. This makes it possible to illuminate the second barrier body 804 with two different colors (e.g., red and green). In particular, the second and fourth light sources 814, 884 may be controllable such that either only the at least one second light source 814 is activated (while the at least one fourth light source 884 is deactivated) or only the at least one fourth light source 884 is activated (while the at least one second light source 814 is deactivated).

[0162] FIG. 9 shows a schematic view of an embodiment of an access control system 988 according to the present application with an embodiment of a passage barrier 990 according to the present application. The passage barrier 990 in the present application comprises a barrier body arrangement 900, which may be formed, for example, in accordance with one of the previously described embodiments. For the sake of a better overview, the details of the barrier body arrangement 900 are not shown in FIG. 9.

[0163] In the present embodiment, the access control system 988 comprises a backend system 991 and at least one passage barrier 990. In particular, a plurality of passage barriers 990 may be provided, for example, at least one passage barrier array (also referred to as a gate array) having a plurality of passage barriers.

[0164] In addition to the barrier body arrangement 900, the passage barrier 988 comprises a base 992. In the present case, the base 992 is formed by two base bodies 992 respectively stand bodies 992. The barrier body arrangement 900 is movably attached to the base 992. By means of at least one actuator 999 (for example an electric motor 999), the barrier body arrangement 900 can be moved respectively displaced between a closed position (as shown in FIG. 9) and an open position. This is indicated by the arrow.

[0165] In particular, the actuator 999 is integrated in the base 992. In the present embodiment, a detection module 994, a light source controller 996, a release equipment 998, a communication module 995, and an interface equipment 989 are further integrated in the base 992. It shall be understood that in other variations of the application, fewer elements may be provided or additional elements may be provided, such as another interface equipment (based on a different transmission technology).

[0166] In particular, the communication module 995 is configured to communicate with a communication module 987 of the backend system 991 via a (wireless and/or wired) distance communication network 997.

[0167] In particular, the at least one interface equipment 989 (e.g., a barcode scanner, a Bluetooth interface, NFC interface, a magnetic stripe reader, etc.) is configured to receive an access authorization (ticket code, user ID, etc.) of the user from a (pre-described) access medium of the user. In particular, a valid access identifier allows passage through the passage barrier 990.

[0168] Upon receipt of an access authorization by the interface equipment 989, the access authorization may be forwarded to the backend system 991 by the communication module 997. An evaluation module 993 of the backend system 991 may check the forwarded access authorization (in a conventional manner), for example, by comparing it to stored permissible access identifiers. In other variants, an evaluation module may also be integrated in the passage barrier.

[0169] The check result may be transmitted to the passage barrier 990 by the communication module 987. For example, if it is determined that the forwarded access authorization is identical to a stored permissible access identifier and the forwarded access authorization is therefore a valid access authorization, a corresponding positive check result may be transmitted. If, for example, it is determined that the forwarded access authorization is not identical to a stored permissible access identifier and the forwarded access authorization is therefore an invalid access authorization, a corresponding negative check result can be transmitted.

[0170] The check result may be provided to the release equipment 998. For example, a release signal may be transmitted when the check result is positive. Based on the check result, the release equipment 998 may control the actuator 999. For example, the actuator 999 may be controlled to cause the barrier body arrangement 900 to move from the closed position to the open position (upon a positive check result).

[0171] The detection module 994 may be configured to detect the current operating state of the passage barrier 990, in particular as previously described. Preferably, at least one of a positive check result and a state control signal may be provided to the detection module 994.

[0172] The detected operating state may be provided to the light source controller 996. Based on the detected operating state and, in particular, an assignment table described above, the light source controller 996 may control the light sources of the light source device of the barrier body arrangement 900, as described in particular above.

[0173] In another embodiment, the light source controller 996 may be configured to illuminate the two barrier bodies of the barrier body arrangement 900 in different colors (for example, red and green) depending on an operating state of the passage barrier device 990, so that a user can recognize whether or not the passage barrier device 900 is usable in the desired direction of passage based on the color of the light decoupling surface 960 as soon as the passage barrier device 900 is approached.

[0174] FIG. 10 shows a diagram of an embodiment of a method according to the present application for operating a passage barrier, such as the passage barrier shown in FIG. 9.

[0175] In a step 1001, a detecting, by a detection module, of the current operating state of the passage barrier may be performed, as described in particular previously.

[0176] In step 1002, controlling, by a light source control, of the light source device of the barrier body arrangement is performed based on an operating state of the passage barrier device, in particular the previously detected operating state of the passage barrier device.

[0177] After a specific period of time has elapsed and/or upon detection of a changed operating state, the light source device of the barrier body arrangement can be controlled again by the light source control, based on a predefined control rule and/or the operating state that is now present. In particular, the control rule can also be integrated in an assignment table.
