Description

TECHNICAL FIELD

[0001] The invention relates to a handrail treatment device comprising at least one housing, a rotating cleaning attachment and a radiation source capable of emitting germicidal electromagnetic radiation, to a personnel transportation equipment comprising at least one handrail treatment device and to a method for controlling a handrail treatment device. BACKGROUND

[0002] Personnel transportation equipment designed as escalators or moving walkways usually have a rotating handrail which moves at the same speed as the conveyor belt on which the users can stand. The users thus grasp the handrail during their journey. The area of the handrail which can be grasped by the users is called the forward run, while its return run is usually covered for the users of the personnel transportation equipment, returning against the transportation direction.

[0003] Through the contact of the hands of the users with the surface of the handrail, bacteria, spores and viruses reach the handrail. The pathogenic agents thus deposited multiply on the handrail and are passed on to subsequent users. The handrail of such a personnel transportation equipment thus represents an unhygienic place in public areas in which infectious diseases can be spread.

[0004] WO 2019 / 164256 A1 shows a handrail treatment device according to the prior art. In this patent document, the handrail is irradiated with ultraviolet light by means of a radiation source. This germicidal electromagnetic radiation destroys the deoxyribonucleic acid of these germs, so that a significant reduction of microorganisms can be found on the surface of the handrail starting from the exit side of the handrail treatment device. However, dirt adhering to the handrail can provide sufficient protection for bacteria and viruses so that they can survive the radiation treatment unscathed.

[0005] In order to be able to achieve an even more thorough disinfection, for example JP 08188369 A provides a comprehensive pre-cleaning using a rotating brush and a cleaning device using a germicidal fluid, so that the cleaned surface of the handrail can then be disinfected by radiation of a UV lamp. However, such a handrail treatment device is very expensive and generates great operating costs, in particular due to the fluid required. SUMMARY

[0006] It is therefore an object of the present invention to render pathogenic agents adhering to the handrail less harmful with a simple handrail treatment device in a cost-effective and safe manner.

[0007] This object is achieved by a handrail treatment device comprising at least one housing and a cylindrical base body arranged in the housing in a manner rotatable about a rotation axis. On the cylindrical outer face of the cylindrical base body, a cleaning attachment is provided, through which the rotating handrail of an escalator or moving walkway can be guided in order to remove dirt particles. Furthermore, at least one radiation source is arranged in the housing, which can emit germicidal electromagnetic radiation. The radiation source is aimed at the base body such that, when the base body is rotated, the cleaning attachment moving past the radiation source is continuously exposed to the germicidal electromagnetic radiation of the radiation source.

[0008] The germicidal electromagnetic radiation to be used preferably has a wavelength range of 200 nm to 280 nm, particularly preferably 250 nm to 260 nm, and can be generated, for example, by means of UV-C tubes or UV-C light-emitting diodes. The cleaning attachment can be a bristle attachment, a foil attachment composed of an elastic material, etc.

[0009] By the continuous exposure of the cleaning attachment to the electromagnetic germicidal radiation, bacteria and viruses adhering to the cleaning attachment are killed before they come into contact with the handrail again in the contaminated area of the cleaning attachment. In other words, what is avoided by irradiating the cleaning attachment is that these germs are brought into the fine cracks and recesses of the handrail, for example, by the non-sterile cleaning attachment and can then still be transmitted to the users of the escalator or moving walkway. By mechanically cleaning the handrail with the disinfected, rotating cleaning attachment according to the subject matter of the application, dirt adhering to the surface of the handrail, which is contaminated with bacteria, can be cleaned, so that the bacterial pressure (the number of bacteria present on the surface) is generally reduced.

[0010] In terms of the shape of the base body, cylindrical merely means that what is involved here is an elongated, rotatably supported body. The base body is preferably constructed rotationally symmetrical, so that imbalances and vibrations induced on the handrail guided through the base body are as small as possible. The base body does not have to be a roll that is necessarily shape-rigid, for example made of steel, but can also be made of a more elastic material, for example a fiber-reinforced plastic or even a soft-elastic material, for example an elastomer, as long as the material can be well rotatably supported in the housing. Logically, a composite of different materials is also possible in order to construct the base body and to equip it with advantageous properties, such as shape rigidity in the bearing points and higher elastic properties in the area of the cleaning attachment.

[0011] In the housing of the handrail treatment device there can be at least one scraping element, whose scraping edge cooperates with the cleaning tips of the cleaning attachment. These cleaning tips are bristle tips for a bristle attachment, lamella tips for a lamella attachment and, for other materials, for example a foam material ring used as cleaning attachment, the porous surface thereof which comes into contact with the handrail. Thereby, dirt which is removed from the handrail and possibly caught in the cleaning attachment is continuously removed from the handrail, so that the area of the cleaning attachment which is mainly cleaned in this mechanical way reaches the handrail again.

[0012] In one design, the scraping element can have a lip or lamella made of a flexurally resilient material. On this lip the scraping edge is configured. Thereby, the cleaning tips which come into contact with the lip are subjected to less mechanical force and thereby their service life is increased. Furthermore, the cleaning tips which pass next to the lip generate vibrations which, although they contribute to the shaking out of dirt from the cleaning attachment, are only weakly transmitted to the housing by the flexurally resiliently configured lip. This makes it possible to significantly reduce the noise generated by the handrail treatment device during operation.

[0013] In an alternative design, the scraping element can have a scraping brush, the bristle tips of which form the scraping edge. The properties of the scraping brush which are relevant for its action are essentially the same as in the above-described design with a lip. Depending on the design of the cleaning attachment (bristle strength, bristle density, arrangement of the bristles or bristle bundles, shape and rigidity of the lamella, etc.), the design with a lip or the design with a scraping brush better cleans the attachment, so that here the selection is preferably made by experiment.

[0014] In one design of the handrail treatment device, the cylindrical base body can be driven by the movement of the handrail guided thereon. However, in order to achieve a sufficient cleaning effect, a speed difference between the surface of the handrail and the cleaning tips of the cleaning attachment is necessary. Such a speed difference can be achieved by continuously braking the rotational movement of the base body or the cleaning attachment, but not completely preventing the rotational movement of the base body or the cleaning attachment. The scraping element which cooperates with the cleaning tips of the cleaning attachment is particularly suitable for this, so that when the handrail moves, a braking effect is thereby generated on the cylindrical base body and a speed difference exists between the surface of the handrail and the cleaning tips which come into contact therewith.

[0015] Alternatively, the cylindrical base body can also be driven by a motor. This makes it possible to match the rotational speed of the cylindrical base body to the speed of the handrail, so that when the handrail moves, a speed difference exists between the surface of the handrail and the cleaning tips which come into contact therewith. The advantage of this alternative is that the rotational speed of the base body can also be significantly higher than the speed of the handrail guided thereon, so that the higher centrifugal forces acting on the dirt particles can be fully utilized for the removal of dirt from the cleaning attachment. In this alternative design, the opposite direction of movement is also possible.

[0016] In another embodiment of the application, the cleaning attachment can be shaped orthogonally to the axis of rotation, such that the running surface profile of the cleaning attachment corresponds to the outer surface profile of the handrail to be guided or cleaned thereon. In this way, not only the wide main surface, on which the user's thenar eminence usually lies, but also both side surfaces, which are usually grasped by the user's fingers, are reached and cleaned by the cleaning attachment.

[0017] In another embodiment of the application, the cylindrical base body can be configured in the shape of a cup and its cylindrical shell surface can have perforations. The cleaning attachment is arranged here on the existing or remaining cylindrical outer surface of the cylindrical shell surface. Furthermore, the interior of the cup-shaped configured base body can be illuminated by a radiation source or another radiation source, such that the germicidal electromagnetic radiation of the radiation source reaches the cleaning attachment through the perforations. With this improvement of the application, the cleaning attachment can also be reached and disinfected to a certain depth by germicidal electromagnetic radiation.

[0018] In another embodiment of the handrail treatment device, a dirt protection device for the at least one radiation source is arranged in the housing, in order to prevent dirt particles that are circulating in the vortex from sticking directly on the radiation source in the housing. Such a dirt protection device can be, for example, a transparent cover for the radiation source or a conductor of various types, which keeps the dirt particles away from the radiation source. However, the dirt protection device can also be, for example, a suction device similar to a vacuum cleaner, which directly sucks the dirt particles that are circulating in the vortex and thereby removes them from the area of the radiation source and the cylindrical base body before they can be deposited and accumulate in the housing.

[0019] In another embodiment of the handrail treatment device, a cleaning device for the at least one radiation source can also be arranged in the housing. Different possibilities exist for this, such as compressed air nozzles directed at the radiation source, a rain wiper system that is operated electromechanically or manually, and the like.

[0020] In another embodiment of the handrail treatment device, a radiation source is provided in the area behind the cylindrical base body with the cleaning attachment in relation to the direction of travel of the handrail. By means of its germicidal electromagnetic radiation, at least a portion of the handrail surface can be illuminated. The handrail that has been treated in this way leaves the handrail treatment device almost sterile. If two possible directions of travel or movement are provided for the personnel transport device, there can also be two areas with radiation sources for illuminating the handrail surface, wherein the cylindrical base body is arranged between these two areas. In order to save energy, the two areas can be activated, for example, in accordance with the direction of movement, so that only the area arranged behind the cylindrical base body and thus in the rear emits germicidal electromagnetic radiation at all times.

[0021] Because the rotating cylindrical base can rotate the cleaned dirt particles through its cleaning attachment, the handrail treatment device preferably has a substantially enclosed housing through which the handrail passes via an inlet and an outlet. To facilitate easier handrail replacement, the housing is preferably designed in two pieces and has a U-shaped main housing portion and a cover spanning the open side of the main housing portion.

[0022] Personnel transport equipment designed as escalators or moving walkways has at least one guardrail including at least one wraparound handrail that a user can hold onto during movement. Typically, two guardrails are present, extending on either side of the conveyor belt of the personnel transport equipment. Preferably, at least one handrail handling device according to the invention is provided for each wraparound handrail.

[0023] In most cases, guardrails include a guardrail base in which the return section of the handrail is concealed from the user within the personnel transport equipment. Therefore, the guardrail base provides the feasibility of concealing the handrail handling device from the user's view by mounting it inside the guardrail base.

[0024] It is known that personnel transport equipment constructed as moving walkways or escalators has a drive motor for driving the handrail and a drive control device for controlling the drive motor. At least one radiation source in a design variation of the handrail handling device described above can be manipulated according to speed and / or direction of movement signals sent to the drive motor by the drive control device. Thus, for example, it is achieved that the at least one radiation source emits sterilizing electromagnetic radiation only when the handrail is in motion. Of course, if the cylindrical substrate is driven by a motor, the rotational speed and / or direction of rotation of the cylindrical substrate can also be controlled according to these signals.

[0025] The embodiments of the present invention will now be described with reference to the accompanying drawings, which should not be construed as limiting the invention. Furthermore, the same reference numerals are used for the same or equivalent elements. Wherein:

[0031] Figure 6 shows Figure 5 cross section of the handrail handling device shown in DETAILED DESCRIPTION

[0032] Figure 1 shows a simplified view of a passenger conveyor 1 with a load bearing structure 11 configured as a frame structure. The passenger conveyor 1, which is designed as an escalator, connects a lower level E1 with an upper level E2 of a building 5. The passenger conveyor 1 can be entered by a user by entering an entry area 3 and leaving it again. In the load bearing structure 11 a rotating step belt 9 is arranged, which is turned in the upper level E2 and in the lower level E1 and thereby has a forward running section and a return running section. For a better overview a detailed illustration of the return section is omitted, as well as a detailed illustration of the slabs, guide rails and track blocks.

[0033] The passenger conveyor 1 also has two balustrades 15, which extend along each longitudinal side of the step belt 9, wherein at Figure 1 only the balustrade 15, which is arranged in the foreground in the viewing plane, is visible in the

[0034] The step belt 9 and the handrail 17 are drivable by a drive unit 7 of the passenger conveyor 1, which has a drive motor 21. The direction of movement and the speed of the handrail 17 and the step belt 9 are predefined by a controller 19, which operates the drive motor 21 by means of control signals, for example by means of a frequency converter, which is not shown.

[0035] Furthermore, the passenger conveyor 1 has at least one handrail handling device 41, 141 for each rotating handrail 17. The handrail handling device is likewise mounted in the balustrade base 13 of the balustrade 15 and is therefore concealed for the user of the passenger conveyor 1.

[0036] In Figure 2 is shown a handrail handling device according to Figure 1Cross section of the personnel transportation device 1 along the straight line A-A. In this cross section, the advancing section and the returning section of the step belt 9 can be seen. The step belt 9 is guided on the guide rails 23 within the load bearing structure 11. On the left and right of the advancing section of the step belt 9, which is arranged above in the normal installation of the personnel transportation device 1, there are arranged the guardrail 15 and the guardrail base 13, respectively. Within the guardrail base 13, there are clamping devices 29 as clamping receptacles for individual guardrail panels 33, which are covered by the cover plates 25, 27. Here, the guardrail panels 33 are clamped position- fixedly on their lower end in at least one of the clamping devices 29. The clamping devices 29 are arranged within the guardrail base 13 on the load bearing structure 11 along the longitudinal extension of the personnel transportation device 1. Below the clamping devices 29, there are provided handrail handling devices 41, 141 for each handrail 17, which is arranged in a loop on the guardrail 15.

[0037] Since the return section of the handrail 17 is also guided in the guardrail base 13, it is advantageous if the handrail handling devices 41, 141 are arranged in the guardrail base 13 and the return section is guided there above or through the handrail handling devices 41, 141 according to the design concept. Thereby, it can be ensured that a user of the personnel transportation device 1 does not come into contact with the handrail handling devices 41, 141.

[0038] Figure 3 Front view showing the first embodiment of the handrail handling device 41 shown in Figure 1 and Figure 2 . Figure 4 Cross section of the handrail handling device 41 shown in Figure 3 along the straight line B-B. The Figure 3 and Figure 4 will be described together below.

[0039] This embodiment comprises a housing 51 and a cylindrical base body 55 which is arranged rotatably about an axis of rotation 53 in the housing 51. On the cylindrical outer face 57 of the base body 55, there is arranged a cleaning attachment 59, through which the cleaning attachment 59 of the handrail 17 can be guided in order to be able to remove dirt particles 61 from the handrail surface 18 of the handrail. Due to the friction between the cleaning attachment 59 and the handrail surface 18, the cylindrical base body 55 is driven by the movement of the handrail 17.

[0040] Furthermore, two radiation sources 43 are arranged within the housing 51, which can emit germicidal electromagnetic radiation. Preferably, for this purpose light tubes or light diodes are used, which can emit, for example, ultraviolet light in the wavelength range of 200 nm to 280 nm, so-called UV-C light, but it is also possible that other radiation sources 43 can emit germicidal radiation. Logically, in order to radiate sufficiently, a row of UV-C LEDs with a slight overlap of a slight cone is required respectively, in order to obtain a germicidal effect over the same width of the housing 51, as one of the UV-C light tubes shown.

[0041] The two radiation sources 43 are aligned to the base body 55 in such a way that the cleaning attachment 59, which continuously passes by the radiation sources 43 when the base body 55 is turned, is exposed to the germicidal electromagnetic radiation of these radiation sources 43. Thereby, the cleaning attachment 59 as well as the dirt removed from the handrail by the cleaning attachment 59 is disinfected, so that the handrail 17 is continuously cleaned by the cleaning area of the cleaning attachment 59 without bacteria and viruses being applied again to the handrail surface 18 by the turning cleaning attachment 59.

[0042] Furthermore, three scraping elements 63, 65 are arranged in the housing 51, the scraping edges 67 of which cooperate with the cleaning tips 69 of the cleaning attachment 59. Thereby, for example the bristles or lamellas of the cleaning attachment 59 are partially spread apart from one another, so that dirt 61 can fall better from the interspaces located therebetween and on the other hand the electromagnetic radiation can penetrate deeper between the bristles or lamellas. Furthermore, the scraping elements 63, 65 brake the rotational speed of the cylindrical base body 55, so that a speed difference occurs between the handrail surface 18 and the cleaning tips 69. This case is symbolically shown in Figure 4 by the non-equal arrows 71, 72 of the handrail speed of the handrail 17 and the rotational speed of the cylindrical base body 55.

[0043] The scraping element 65 can have a lip made of a flexurally resilient material, wherein the scraping edge 67 is configured on the lip. But the scraping element 63 can also be a scraping brush, the bristle tips of which form the scraping edge 67. In principle, all scraping elements 63, 65 of the handrail treatment device 41 can have the same configuration. As is clearly visible in Figure 4 a combination of the two design variants of the scraping elements 63, 65 can also be used in the same device.

[0044] In order to be able to remove the dirt particles 61 accumulated in the housing 51, a dirt removal device 75 can be present. In the present embodiment, this is a simple drawer element, which can be emptied from time to time by a service person. Of course, as a dirt removal device 75 on the housing 55 a connection for a suction device can also be present, in order to be able to automate the continuous or periodic suction of the accumulated dirt 61.

[0045] Figure 5 as a second embodiment in a front view Figure 1 and Figure 2 the handrail treatment device 141 shown. Figure 6 is shown Figure 5 a cross section of the handrail treatment device 141 along the straight line C-C. The following will be described together Figure 5 and Figure 6 .

[0046] The second embodiment has, like the first embodiment, a plurality of components with the same function, such as the housing 151 and the cylindrical base body 155 arranged rotatably about the rotation axis 53 in the housing. The wiping element 65 for the germicidal electromagnetic radiation, for example UV-C light, and the radiation source 43 are also arranged in the housing 151.

[0047] The main difference to the first embodiment is that the cylindrical base body 155 can be driven by a motor 177. Here, the rotational speed of the cylindrical base body 155 is preferably coordinated with the speed of the handrail 17, so that there is a speed difference between the handrail surface 18 and the cleaning tip 69 contacting this handrail surface when the handrail 17 is moving. If necessary, the rotational direction of the base body 155 opposite to the handrail surface 18 can also be selected, as is shown by the arrows 71, 72, 73, 74 shown in solid or dashed lines.

[0048] Another difference is that the cylindrical base body 155 is configured cup-shaped and that its cylindrical shell surface 181 has perforations 183. The cleaning attachment 59, in this embodiment bristles, is arranged on the cylindrical outer face 57 of the existing cylindrical shell surface 181. The interior 185 of the cup-shaped configured base body 155 is illuminated by the radiation source 43 arranged therein in such a way that its germicidal electromagnetic radiation reaches the cleaning attachment 59 through the perforations 183.

[0049] In order not to allow dirt 61 to collect on the upper side of the radiation source 43 due to gravity, a dirt protection device 187 for the radiation source 43 is arranged in the housing 151. In addition, the base body can be provided with a reflection surface 189 facing the radiation source 43, so that radiation hitting the reflection surface 189 is reflected into other regions of the interior 185 of the base body 155.

[0050] In addition, as shown in Figure 5 , there can be a cleaning device 191 for at least one radiation source 43. The cleaning device is exemplarily configured as a brush ring 193 which is movable over the radiation source 43 by means of a lever 195. Preferably, there is a cleaning device 191 and / or a dirt protection device 187 arranged in the housing 151 for each radiation source 43.

[0051] As can be seen from Figure 6It can be seen that the second embodiment of the handrail treatment device 141 has a region 197, 199 arranged behind the cylindrical base body 155 with the cleaning attachment 59, which region has the radiation source 43. This region 197, 199 arranged behind is coordinated with the direction of movement of the handrail 17, that is to say, it is arranged in such a way that the sterilizing electromagnetic radiation radiated from its radiation source 43 cleans the handrail 17 cleaned by means of the cleaning attachment 59. If the personnel transportation device 1 is able to run in two conveying directions, then such a region 197, 199 arranged behind can also exist on both sides of the base body 155, as shown by the dashed lines. The radiation source 43 can then be operated depending on the conveying direction of the personnel transportation device 1, for example.

[0052] In order to protect the cleaning attachment 59 from environmental influences and, if present, to cover the radiation source 43 of the region 197, 199 arranged behind for safety reasons, the housing 151 can be implemented in two parts and have a main housing part 149 with an open side and a cover 147 spanning the open side of the main housing part 149.

[0053] In both of the aforementioned embodiments of the handrail treatment device 41, 141, the cleaning attachment 59 is also shaped orthogonally to the rotation axis 53, so that the running face contour of the cleaning attachment 49 corresponds to the outer face contour of the handrail 17 to be guided. By this means, the side edges 16 of the handrail 17 can also be cleaned and disinfected.

[0054] Although Figures 1 to 6 The different aspects of the application are shown by means of a personnel transportation device 1 designed as an escalator, which connects floors E1, E2 vertically spaced apart from one another, but it is immediately apparent that the handrail treatment devices 41, 141 presented can also be used in a moving sidewalk arranged obliquely or in a moving sidewalk arranged horizontally. Furthermore, the region 197, 199 behind can also have a plurality of radiation sources 43 each and be arranged in different planes, so that the entire handrail surface 18 accessible to the user of the personnel transportation device can be directly illuminated by the radiation sources. Furthermore, instead of the motor 177, a friction wheel, which acquires the movement of the handrail 17, can also be used, which can drive the base body 155 by means of a reduction or a variable transmission.

[0055] Finally, it is to be noted that expressions like "having", "including", etc. do not exclude other elements or steps and expressions like "one" or "said" do not exclude pluralities. Furthermore, it is to be noted that features or steps described with reference to one of the above described embodiments can also be used in combination with other features or steps of other embodiments described above. Reference signs in the claims shall not be considered as limiting the scope.
