Description

Technical Field

[0001] The present invention relates to a barrier that provides fall protection for users of a transport device, and to a transport device having such a barrier. Background Technology

[0002] In this document, the transport device is an escalator or moving walkway with a conveyor belt (which has a number of steps or platforms). The steps or platforms form a transport surface for transporting users and / or other loads, such as hand luggage or shopping carts.

[0003] Handrails are typically arranged on the sides of steps or platforms of a transport device. Below the handrail is a support structure to which the handrail is attached. The support structure is covered at the top by a cover assembly and laterally by side panels. The cover assembly and the side panels are typically attached to the support structure by means of attachments (which are also designed for this purpose).

[0004] For transport devices, the height of their railings or handrails (starting from their transport surface) is subject to building codes and standards (e.g., EN-115). These building codes are designed to ensure the safe use of escalators or moving walkways, and these building codes must be strictly observed by operators or building owners.

[0005] Because the railings on conventional transport devices only extend to the height of the handrails, certain risks associated with improper use exist. Therefore, users sometimes intentionally jump over the railings, or are unintentionally pushed over them. This occurs, for example, in football stadiums, when a hooligan jumps off the transport device or pushes other users off. Other deplorable customers include those "surfing" the handrails or using their hands to hold onto the handrails while their bodies are freely hanging outside the transport device. Users may also become trapped if the transport device passes through another intersecting transport device or through narrow floor openings. This situation is dangerous for both users of the transport device and those below it, and therefore must be avoided at all costs.

[0006] For example, WO 2020 / 114846 A1 discloses a handrail for an escalator, wherein a first panel is arranged below the handrail and, as an additional barrier, a second panel is arranged to be laterally offset from the handrail and project above it. This barrier effectively reduces the risk of falls. Furthermore, it extends along the entire length of the handrail to prevent users from "surfing" on the handrail or "pulling themselves" along the barrier. The barrier results in significantly higher manufacturing, transportation, and installation costs, and due to its higher weight, it imposes strain on the support structure of the escalator or moving walkway. Summary of the Invention

[0007] In this context, the object of the present invention is to provide a barrier that is as lightweight and inexpensive as possible. In particular, the objective is to create a barrier that is easy and quick to install, visually appealing, and functions as a fall protection device. Furthermore, it should be easy to modify transport devices incorporating such a barrier.

[0008] This objective is achieved by protecting users from falling out of a transport device configured as an escalator or moving walkway. The barrier is constructed to be mounted on the transport device as a circular, movable handrail near the handrail, wherein, in the installed state, the barrier extends parallel to the handrail and protrudes in height beyond the handrail or handrail. Furthermore, the barrier has a deflector and a panel area adjacent to the deflector, having at least one barrier panel. The deflector prevents people from pulling themselves past the point along the outside of the transport device to climb over the barrier and handrail in the ascending area and thus enter the escalator or moving walkway from the side. As disclosed in WO 2020 / 114846A1, the deflector allows the barrier to be kept shorter, and the deflector does not need to extend to the return bend of the handrail to prevent the aforementioned problems. Furthermore, the deflector serves as a post and attachment element for the adjacent panel area at the transport device.

[0009] In addition to the at least one barrier panel, the barrier also has a clamping profile with a V-shaped groove extending longitudinally into the clamping profile. The V-shaped groove is defined by a groove base and two groove surfaces, which are arranged at an angle to each other in a direction from the groove base toward the groove opening. The clamping profile may be made of an extruded profile bar or a pressed profile bar. The clamping profile may be made of extruded aluminum or extruded plastic. For example, its ends may be covered with end caps or lead to the deflector. Because the barrier panel is a plate-like structure, it includes at least two parallel side surfaces and a lower edge relative to its intended mounting position. The barrier panel is positioned such that its lower edge lies within the V-shaped groove.

[0010] Another component of the barrier is an L-shaped wedge insert with wedge-shaped legs and a base leg. The wedge-shaped legs have a wedge-shaped cross-section and are arranged between a first side surface of the barrier panel and the surface of the first groove. The base leg is arranged between the lower edge of the barrier panel and the base of the groove.

[0011] Additionally, the barrier has a clamping wedge with a wedge-shaped cross-section, which is disposed between the second side surface of the barrier panel and the second groove surface. In this case, the wedge insert and the clamping wedge do not necessarily extend continuously in the V-groove, or their lengths do not necessarily match the length of the barrier panel.

[0012] For cost, manufacturing, and installation reasons, the wedge inserts and clamping wedges are configured to be significantly shorter than the barrier panels, allowing them to be used in the bending sections of the clamping profile without having to bend in the longitudinal extension of the clamping profile. Preferably, the wedge inserts and clamping wedges are arranged opposite each other in the V-groove and not offset from each other in the longitudinal direction to avoid additional bending moments on the barrier panels due to the clamping force generated by the driven clamping wedges. Multiple wedge inserts and clamping wedges can be provided from each barrier panel, thereby providing a distance greater than the length of the wedge insert or clamping wedge between two pairs of wedge inserts / clamping wedges.

[0013] The L-shaped wedge insert provides components whose dimensions are sufficiently stable to withstand the forces exerted on the barrier panel when inserted into the V-shaped groove. Furthermore, the barrier panel is precisely positioned within the V-shaped groove by the wedge insert, allowing multiple barrier panels arranged adjacent to each other in series to be precisely positioned relative to each other without effort. Additionally, the wedge insert, preferably made of a polymer material such as acrylonitrile butadiene styrene copolymer (ABS), polyethylene terephthalate (PET), polyamide (PA), etc.), provides excellent vibration absorption, significantly reducing the risk of breakage of the barrier panel, thus allowing its thickness to remain relatively low.

[0014] In one embodiment of the barrier, the deflector includes a support plate having a foot attachment area and a panel connection area. The deflector is configured such that, when the barrier is mounted on the transport device, its support plate extends in the same vertical spatial plane as at least one barrier panel in the adjacent panel area. The deflector plate is arranged on the support plate in a plane parallel to the support plate and thus spaced apart from the support plate. The deflector plate has smooth edges and surfaces that do not provide gripping areas for hands or feet. Preferably, the distance to the support plate is selected such that, when the barrier is in the mounted state, the deflector plate is flush with the vertical side panel of the transport device. Furthermore, during climbing attempts, the edges of the deflector plate create pressure points on the body, resulting in an "unpleasant" sensation, causing climbing attempts to be aborted and abandoned in most cases.

[0015] In one embodiment, the deflector plate is attached to the support plate via a recessed connector. This prevents the formation of a horizontal surface that could be used as a climbing aid.

[0016] In another embodiment of the barrier, a connection point matching the panel connection area is formed on an edge region of at least one barrier panel. In other words, the connection point and the panel connection area match each other, allowing the support plate and the barrier panel to be securely connected with minimal effort using fasteners (such as screws, clamps, connecting strips, adhesives, etc.). The connection point and the panel connection area may be configured to overlap each other, include holes, have appropriately prepared adhesive surfaces, etc.

[0017] In another embodiment, a vertical deflector edge is formed on the at least one barrier panel relative to the intended installation location of the barrier. The deflector edge protrudes beyond the upper edge of the barrier panel and is equipped with a cylindrical deflector profile. A barrier panel equipped with a deflector profile is used where the transport device is near intersecting transport devices or passes through a narrow floor opening. Without the deflector edge, in the area of ​​the floor opening, a wedge-shaped gap is formed between the upper edge of the barrier panel and the lower side of the intersecting transport device or the lower side of the ceiling; for example, an extended arm can be trapped in this wedge-shaped gap. The vertical deflector profile effectively mitigates this danger zone.

[0018] The barrier panel (whether or not it has a deflector edge) is preferably made of a transparent material. This can be single-pane safety glass, laminated safety glass, PMMA sheet, polycarbonate sheet, etc. The barrier panel can also be made of opaque materials, such as wood, composite materials, metal, or opaque polymer materials.

[0019] In another embodiment, the connection point for the safety device of the structure is formed on the deflector, and / or the clamping profile, and / or the support of the barrier described below. The safety device may be a structural mesh railing, a barrier panel, etc.

[0020] In another embodiment, an attachment area for the end face of the clamping profile is formed in the panel connection area of ​​the deflector. This provides additional strength to the assembly of the deflector and the barrier plate.

[0021] In another example of the barrier, the V-shaped groove on the surface of the first groove of the wedge insert has a protrusion that narrows the opening of the groove. The protrusion, together with the groove base and the surface of the first groove, forms a lateral pocket in which the wedge-shaped legs of the wedge insert can be placed. During the installation and removal of the barrier panel, the protrusion secures the wedge insert in the V-shaped groove, holding it in the provided position within the groove. This significantly simplifies the installation process and allows it to be performed even by less qualified assemblers.

[0022] In another example of the barrier, an elastic element is arranged on the wedge-shaped legs of the wedge-shaped insert. When the wedge-shaped insert is inserted into the V-shaped groove, the elastic element clamps the wedge-shaped legs of the insert between the protrusion and the base of the groove. Therefore, the elastic element secures the wedge-shaped insert, even better, within the V-shaped groove, particularly resisting displacement in its longitudinal direction. This is particularly advantageous in inclined sections of escalators, preventing the wedge-shaped insert from sliding "downhill".

[0023] In another embodiment of the barrier, attachment structures for the resilient sealing profile are formed on both sides of the groove opening of the V-groove. The sealing profiles arranged on both sides prevent dust and water from penetrating the V-groove and give the transition (the transition from the clamping profile to the barrier panel) an aesthetic appearance.

[0024] In another example of the barrier, a T-shaped groove is formed on the side of the clamping profile opposite to the V-shaped groove and is configured to receive an attachment. This allows the clamping profile to be attached to a suitable structural component of the transport device, or to be attached to the transport device via an adapter. Furthermore, clamping profiles divided into multiple sections can be securely connected to each other at their end faces by means of connecting tongues (connecting tongues that insert into the T-shaped groove).

[0025] In another embodiment of the barrier, it has a support member with a foot attachment area at one end and a head attachment area at the other end. The head attachment area is connected to the clamping profile by means of an attachment member arranged in a T-groove of the clamping profile. The T-groove in the longitudinal direction of the clamping profile allows for free selection of the position of the support member on the clamping profile. The foot attachment area is configured to be attached to a bearing structure of the transport device, such as a supporting structure thereto.

[0026] In one possible embodiment of the support, a telescopic device is arranged between the head attachment area and the foot attachment area. This allows for a fixed adjustment of the support distance between the head attachment area and the foot attachment area.

[0027] In another example of the barrier, the barrier has a connecting element. The connecting element is connected at one end to a clamping profile or support, and at the other end is configured such that it can be attached to a handrail guide profile of the transport device. This connection between the railing and the barrier, which supports each other orthogonally to the longitudinal direction of the clamping profile, allows both the railing and the barrier to be constructed and built with reduced material thickness.

[0028] Depending on their location within the building, transport devices configured as escalators or moving walkways may be equipped with barriers on one or both sides. Such transport devices typically have a circulating conveyor belt with railings on both sides of the conveyor belt, the railings having circulating, movable handrails. According to the invention, the barrier is installed beside the circulating, movable handrail on the transport device, wherein the barrier is arranged on the side of the handrail facing away from the conveyor belt. In the installed state, the barrier extends parallel to the railing and protrudes in height beyond the railing or its handrail. Attached Figure Description

[0029] Preferred exemplary embodiments of the invention are explained in more detail in the following description with reference to the accompanying drawings; in all the drawings, the same reference numerals are used for the same elements. Neither the drawings nor the description should be construed as limiting the invention. In the drawings:

[0034] Figure 5 It shows crossing Figure 1 A cross-section of the entire barrier and glass railing of the transport device shown. Detailed Implementation

[0035] Figure 1 A three-dimensional view of a transport device 1 configured as an escalator is shown, as it is installed in structure 3 (indicated by dashed lines). The transport device 1 has a circulating, movable conveyor belt 5 with steps 7. Handrails 9 with glass panels 11 extend along each side of the conveyor belt 5. Transport devices 1 with such glass handrails are used, for example, in department stores and shopping malls. A handrail guide profile 13 with circulating, movable handrails 15 (see...) Figure 5 The handrails 15 are arranged at the edges of each railing 9. The handrails 15 move synchronously with the conveyor belt 5. The height H of the railings 9 is... B The handrail 15 has been adjusted so that it can be comfortably gripped by adults of average height, while also being easily accessible to shorter children. For example, EN-115 adjusts the handrail height H according to the location of use. B The specified range is 900cm to 1100cm.

[0036] Because there is no wall extending on either side of the transport device 1, during the aforementioned improper use, the user could fall over the railing 9 and tumble down the side of the transport device 1. To prevent this, barriers 31 are installed on both sides of the handrail 15 on the transport device 1. Figure 1 It can be seen that the barrier 31 extends parallel to the railing 9. Its barrier panel 45 protrudes beyond the railing height H. B Or handrail 15-height H A To allow the user to grip the handrail 15, a barrier 31 is arranged on the side of the handrail 15 facing away from the conveyor belt 5.

[0037] To illustrate various embodiments of the barrier 31, the barrier panel 45 mounted on the right barrier 31 is made in one piece. As shown in the left barrier 31, the barrier 31 may also have multiple barrier panels 45. In this case, the barrier 31 may have panel connectors 145 to connect the individual barrier panels 45 to each other.

[0038] In addition, each barrier 31 has at least one deflector 29, wherein one or two deflectors 29 are provided for each barrier 31 depending on the expected direction of travel L and the building structure. Figure 1The conveyor 1 shown can operate in both upward and downward conveying modes, as indicated by the double arrows in the direction of travel L. Therefore, two deflectors 29 are positioned at the ends of the barrier 31, wherein the deflectors 29 are arranged in the upper plane of the structure 3, in front of the safety device 4 of the structure 3 (e.g., the grid railing shown). A panel area 22 with a barrier panel 45 extends between the two deflectors 29, thus abutting them. The deflectors 29 prevent people from pulling themselves beyond the point along the outside of the conveyor 1 to climb the conveyor 1 in the ascending area. Figure 1 As can be seen, the connection point 28 of the safety device 4 in structure 3 is formed on the support member 75 of the barrier 31. The connection point 28 provides mutual support between the barrier 31 and the safety device 4 against lateral forces. Alternatively or additionally, the connection point 28 may also be formed on the deflector 29 (see...). Figure 2 () and / or formed on the clamping profile 33 described below.

[0039] Furthermore, the deflector 29 serves as a dimensionally stable post for attaching the barrier panel 45 adjacent to the panel region 22 to the transport device 1. For this purpose, the deflector 29 includes a support plate 25 having a foot attachment region 26 and a panel connection region 27. The support plate 25 extends in the same vertical spatial plane as at least one barrier panel 45 adjacent to the panel region 22. The foot attachment region 26 is configured such that it can be securely attached to the load-bearing member, for example, by means of clamps, screws, rivets, adhesives, etc. An example of such a load-bearing member is... Figure 5 The support structure 101 shown, or the railing clamp 103 attached to the bearing component.

[0040] In this exemplary embodiment, the adjacent barrier panel 45 is securely connected to the support plate 25 via a panel connector 145. A deflector plate 23 is arranged on the support plate 25 in a plane parallel to the support plate 25 and thus spaced apart from the support plate 25 by a distance X. The deflector plate 23 has smooth edges and surfaces that do not provide gripping portions for hands or feet. Preferably, the distance X from the support plate 25 is selected such that the deflector plate 23 is arranged flush with the vertical side panel 6 of the transport device 1. The deflector plate 23 is attached to the support plate 25 via a recessed connector 24. This prevents the formation of a horizontal surface that could be used as a climbing aid.

[0041] Figure 2A side view shows two closely adjacent intersecting transport devices 1 with a fixed direction of travel L. Both transport devices 1 also have a barrier 31, whose deflectors 29 are arranged according to the direction of travel L. To limit the fall height of a denied user, the height Y of the foot attachment area 26 relative to the floor 2 of the structure 3 is specified by a "standard". This height Y also determines how much shorter the barrier 31 can be compared to a conventional barrier. Furthermore, the barrier 31 of the upward-moving transport device 1 has a barrier panel 45A with a vertical deflector edge 44. This deflector edge 44 protrudes beyond the upper edge 88 of the barrier panel 45A and is provided with a cylindrical deflector profile 42 so that, for example, the user's clothing will not get caught at the deflector edge 44.

[0042] from Figure 2 As can be seen, if the deflector edge 44 is missing, the upper edge 88 of the barrier panel 45 forms a wedge-shaped gap in the area of ​​the floor opening 89 with the lower side 87 of the intersecting transport device 1 or the lower side of the ceiling 86 of the structure 3, where, for example, an extended arm can be caught in the wedge-shaped gap. By providing a vertical deflector edge 44, the wedge shape of the gap is effectively reduced, and the added cylindrical deflector profile 42 completely prevents clothing from getting stuck in the gap. Therefore, the barrier panel 45A equipped with the deflector profile 42 is used when the transport device 1 is near the intersecting transport device 1 and / or passes through the narrow floor opening 89 relative to its intended direction of travel L.

[0043] Figure 3 It shows Figure 2 The enlarged cross-sectional view of the barrier panel 45A shown in the designated section AA illustrates the cylindrical structure of the deflector profile 42. Furthermore, the barrier panel 45A, with its deflector edge 44, has a molded attachment flange 84 with a hole 83 for additional attachment to the underside 87 of the intersecting transport device 1. The barrier panels 45, 45A are preferably made of a transparent material. This could be single-pane safety glass, laminated safety glass, PMMA sheet, polycarbonate sheet, etc. However, the barrier panels 45, 45A can also be made of opaque materials, such as wood, composite materials, metal, or opaque polymer materials.

[0044] Figure 4 Schematic illustration of crossing Figure 1 An enlarged view of the cross-section of the barrier 31 is shown. The barrier 31 has a clamping profile 33 with a V-groove 35, wherein, when the barrier 31 is in the installed state, the clamping profile 33 is positioned in the travel direction L of the transport device 1 (see [reference]). Figure 1The V-shaped groove 35 extends upwards. It is defined by a groove base 37 and two groove surfaces 39, 41. In this case, the groove surfaces 39, 41 are arranged at an angle relative to each other, extending from the groove base 37 to the groove opening 43. In other words, the width of the V-shaped groove 35 increases in the direction toward the groove opening 43. The clamping profile 33 can be made, for example, of an aluminum extrusion profile or an extruded plastic profile, and its end can be securely connected, for example, to an adjacent deflector 29 (see...). Figure 1 and Figure 2 For this purpose, an attachment area 54 for clamping the end face of the profile 33 is provided in the panel connection area 27 of the deflector 29.

[0045] The barrier 31 also has barrier panels 45, 45A, which have two parallel side surfaces 47, 49 and are arranged in a V-shaped groove 35 in the region of their lower edge 51. As mentioned above, the barrier panel 45 can be made of a transparent material, such as single-pane safety glass, laminated safety glass, PMMA sheet, polycarbonate sheet, etc. The barrier panel 45 can also be made of an opaque material, such as wood, composite material, metal, or opaque polymer material.

[0046] Another component of the barrier 31 is an L-shaped wedge insert 53 having a wedge-shaped leg 55 and a base leg 57. The wedge-shaped leg 55 has a wedge-shaped cross-section and is arranged between the first side surface 47 of the barrier panel 45 and the first groove surface 39. The base leg 57 of the wedge insert 53 is arranged between the lower edge 51 of the barrier panels 45, 45A and the groove base 37. Additionally, a channel 58 is formed in the base leg 57 and extends parallel to the V-shaped groove 35. Forming the channel 58 in the base leg 57 has the following advantages: for example, a light-emitting device 151 can be placed in the V-shaped groove 35 with a constant cross-section or within the clamping profile 31 without interruption. All known light-emitting devices (such as light-emitting diodes, fluorescent tubes, OLED films, etc.) can be used as the light-emitting device 151. The channel 58 also allows for easy placement of electrical conductors (such as signal lines 157 and power lines 155) in the V-shaped groove 35. In order to connect the electrical conductors, they can be guided through the cavity (not shown) of the deflector 29 into the interior of the transport device 1.

[0047] To securely anchor the wedge insert 53 and the barrier panel 45 within the clamping profile 33, the barrier 31 has a clamping wedge 59 with a wedge-shaped cross-section, which is inserted between the second side surface 49 and the second groove surface 41 of the barrier panel 45. To ensure the barrier panel 45 is securely and permanently clamped within the V-groove 35, the wedge angle α of the wedge leg 55 and the wedge angle β of the clamping wedge 59 must be less than the friction cone angle, which exists between the first groove surface 39 and the wedge leg 55 or between the second groove surface 41 and the clamping wedge 59. The friction cone angle is another way of describing the coefficient of friction between these components, which depends on the surface roughness and the materials of the clamping profile 33, the wedge insert 53, and the clamping wedge 59. In the case of a barrier 31 having multiple barrier panels 45, the wedge insert 53 and the clamping wedge 59 are preferably arranged in the clamping profile 33 so as to overlap with two adjacent barrier panels 45.

[0048] The V-groove 35 also has a protrusion 61 on the first groove surface 39 (which is provided for the wedge insert 53) that narrows the groove opening 43. This protrusion 61 allows the wedge insert 53 to be better held in the V-groove 35, preventing it from slipping when the barrier panel 45 is inserted. To further improve this retention, an elastic element 63 can be arranged on the wedge-shaped legs 55 of the wedge insert 53, clamping its wedge-shaped legs 55 between the protrusion 61 and the groove base 37 when the wedge insert 53 is inserted into the V-groove 35.

[0049] To prevent the V-groove 35 from becoming filled with water and dust, sealing profiles 65 and 67 of an elastomeric material (such as rubber, nitrile rubber, etc.) are arranged at the groove openings 43 on both sides of the barrier panel 45. To allow the sealing profiles 65 and 67 to be installed, attachment structures 69 are formed on both sides of the groove openings 43 of the V-groove 35. These attachment structures 69 (shown as tongue-groove connectors) correspond to the corresponding structures on the sealing profiles 65 and 67. Figure 4 The tongue-groove attachment structure 69 shown is only one of many possible designs for attaching sealing profiles 65, 67 to the groove opening 43, and therefore should not be construed as a simplification of this representation.

[0050] To allow the barrier 31 to be attached to the transport device 1, a T-groove 71 is formed on the side of the clamping profile 33 facing away from the V-groove 35. An attachment 73 (e.g., a square or hexagonal screw head) can be arranged therein, wherein its position in the longitudinal direction L of the clamping profile 33 is freely selectable. This simple and robust construction allows the clamping profile 33 to be attached to, for example, a support 75 and / or a deflector 29, such as... Figure 1 and Figure 2 As shown. Of course, other structures (such as holes with internal threads, clamping protrusions, etc.) can also be formed on the clamping profile 33 so as to connect it to the transport device 1.

[0051] Figure 5 It shows crossing Figure 1 The diagram shows a cross-section of the entire barrier 31 and railing 9 of the transport device 1. In addition to the clamping profile 33, barrier panel 45, wedge insert 53, and clamping wedge 59, the barrier 31 also has a support 75 with a foot attachment area 77 at one end and a head attachment area 79 at the other end. The head attachment area 79 is connected to the clamping profile 33 by means of an attachment element 73 arranged in a T-groove 71 of the clamping profile 33. The foot attachment area 77 of the support 75 is screwed to the railing clamp 103 of the transport device 1, and the railing clamp 103 is attached to the support structure 101 of the transport device 1 (only its upper chord is shown). The support structure 101 is a load-bearing structure that houses all components of the transport device 1 and supports its mass and its own mass within structure 3. The glass panel 11 of the railing 9 is clamped in the clamping device 103 of the railing clamp.

[0052] To enable mass production of the support 75 rather than for specific contracts, a telescopic device 81 is arranged between the head attachment region 79 and the foot attachment region 77. The telescopic device 81 is formed of a two-part support tube, wherein the two parts of the support tube are connected to each other by threads 82, allowing adjustment in the axial direction B. With the aid of this telescopic device 81, the support distance Z between the head attachment region 79 and the foot attachment region 77 can be fixedly adjusted, thereby compensating for manufacturing tolerances of the support structure 101 and, on the other hand, ensuring the desired height H of the barrier panel 45 is achieved. A It can be adjusted according to deflector 29 (see Figure 1 ).

[0053] The barrier 31 also has a connecting element 85, which is connected at one end to the support 75. The other end of the connecting element 85 is attached to the handrail guide profile 13 of the transport device 1. This stabilizes the support 75 and the railing 9 of the transport device 1 against transverse longitudinal directions L (see also) of the barrier 31. Figure 1 The force acting on the railing 9 and the barrier 31.

[0054] Although Figure 1 and Figure 2 The diagram shows a transport device 1 clearly configured as an escalator, but it is obvious that the barrier 31 can also be used for a moving walkway.

[0055] Finally, it should be noted that terms such as "having" or "containing" do not exclude other elements, components, or steps, and terms such as "a" or "an" do not exclude multiple. Furthermore, it should be noted that features or steps already described with reference to one of the exemplary embodiments described above may also be used in combination with other features or steps of the other exemplary embodiments described above. Reference numerals in the claims should not be considered limiting.
