Description

The invention relates to a passenger transport device with an endless conveyor belt and an endless handrail. Laterally of the conveyor belt, a transparent balustrade is arranged, which comprises at least a first glass sheet, which supports the handrail. It is known to provide such transparent balustrades with lighting devices, for example, to illuminate the conveyor belt for the passengers. Furthermore, such lighting also serve purely aesthetic purposes or promotional purposes.

For the purposes of this application, a passenger transport device is understood as meaning both escalators and horizontal or oblique treadmills. Likewise, the term "transparent pane" summarizes both glass panes and plastic panes.

From the EP 1 814 815 is a passenger transport device with a transparent balustrade known. In this case, the transparent balustrade comprises a transparent pane which cooperates with a profile, wherein a plurality of LEDs for illuminating the balustrade is arranged between the profile and the pane.

This arrangement has the disadvantage that to repair the lighting device, the profile must be removed. However, since typically the profile in the base area supports the balustrade panel or ensures the support of the handrail on the balustrade panel in the handrail area, this means that complete disassembly of the balustrade is required.

Object of the present invention is to develop the transparent balustrade such that the transparent balustrade can be illuminated by means of a lighting device and at the same time a simple replacement of the lighting device is possible.

This object is achieved by a passenger transport device comprising an endless conveyor belt, an endless handrail and a transparent balustrade, which is arranged laterally of the conveyor belt and comprises at least a first transparent disc, which supports the handrail. According to the invention, the transparent balustrade further comprises at least one second transparent pane, which is provided in front of the first transparent pane, wherein the second transparent pane is connected to a lighting device for generating illumination radiation. In addition, the second transparent pane has a structuring for coupling out illumination radiation from the second transparent pane.

This arrangement has the advantage that the lighting device can be mounted without affecting the support of the handrail. The invention is based on the idea of making a division according to different functions. The first transparent pane serves mainly to support the handrail while the second transparent pane is designed to illuminate the transparent balustrade. Thus, both discs can be configured according to their function. This arrangement has the further advantage that existing passenger transport facilities can be retrofitted. Existing passenger conveyors typically already include a first transparent panel supporting a handrail. By subsequent Vorsetzen a second transparent pane with connected lighting device thus the passenger transport device can be retrofitted in a simple way with a modern lighting.

In an advantageous embodiment variant, the first transparent pane and the second transparent pane have different types of glass. The use of glass for the transparent panes has the advantage that glass is inexpensive to produce and is particularly insensitive to scratching. Furthermore, glass has the advantage over plastic that it is long-term stable and significantly less degraded due to irradiation. The use of different types of glass has the further advantage that the type of glass can be selected specifically for the respective main function of the disc. Since the first transparent pane supports the handrail, it is advantageous for this pane to use a type of glass which can withstand greater loads.

For example, the first transparent pane has a safety glass and the second transparent pane has a simple float glass. A simple float glass is understood to mean a flat glass which has been produced by the float process and which does not meet the standards for a single-pane safety glass ( DIN EN 12150-1 ) nor the standards for a semi-tempered glass ( DIN EN 1863-1 ) Fulfills. This results in a laminated safety glass. This combination provides a robust and cost-effective balustrade. Thanks to the safety glass, the balustrade can withstand even high loads, while the use of simple float glass means that the costs for the balustrade are kept low.

The glass material of the first transparent pane is particularly preferred and / or the second transparent pane around a white glass. This allows a particularly efficient illumination, since there is only low absorption of the illumination radiation in the glass material. In addition, no color distortions occur.

During operation of the illumination device, illumination radiation is coupled into the second transparent pane. The coupled-in illumination radiation now propagates within the second transparent pane and the first transparent pane. When the illumination radiation impinges on the boundary surfaces of the second transparent pane or the first transparent pane, at least part of the illumination radiation is reflected back into the first or second transparent pane. Only a small part of the illumination radiation emerges when hitting an outer surface of the transparent balustrade and thereby illuminates the transparent balustrade. Optionally, this division into reflected and transmitted portion of the illumination radiation is deliberately set by a surface coating of the first transparent pane and / or the second transparent pane. The fact that the second transparent pane has a structuring for coupling out illumination radiation from the second transparent pane results in special lighting effects for the external viewer. The structuring can be achieved for example by means of sand blasting or by acid treatment. Particularly preferably, the structuring comprises an outer engraving, which has been produced for example by means of laser engraving. Illumination radiation impinging on the structuring is scattered on the structuring and thus decoupled from the disks. As a result of the scattering, the angles of incidence on the outer surfaces of the two panes change, so that the scattered illuminating radiation is for the most part not reflected back into the panes but emerges from the panes. Thus, for observers on both sides of the transparent balustrade brightly illuminated areas arise on the panes, which have the form of structuring. For example, the areas may be in the form of characters or logos. Alternatively, abstract patterns and embellishments can be highlighted.

An embodiment of the second disc made of simple float glass has the further advantage that also inside engravings can be made in this disc. This happens, for example, by laser engraving process. An appropriate interior engraving of safety glass is not possible. Safety glass is thermally treated during production, so that a tension builds up in the material. When attempting an interior engraving, these stresses lead to the shattering of the safety glass.

However, interior engravings have the advantage that three-dimensional structures can also be incorporated into glass, resulting in a wider range of creative possibilities. The combination of the two types of glass therefore allows the advantages of safety glass to be retained while at the same time opening up new creative possibilities.

In a further embodiment of the passenger transport device, the second transparent pane is connected to the first transparent pane by lamination. As a result, the two discs can be firmly connected to each other over the entire surface. In addition, it is possible to dispense with additional connecting elements which have a shading effect and therefore impair the design of the transparent balustrade.

Preferably, the passenger transport device is further configured such that the second transparent pane has at least one coupling-in region, at which the illumination radiation generated by the lighting device is coupled into the second transparent pane. This allows a well-defined entry of the illumination radiation into the second transparent pane. This coupling-in area is arranged, in particular, on the end face adjacent to the handrail and / or on the end face of the second transparent pane opposite the handrail. The arrangement on an end face has the advantage that the coupled illumination light automatically strikes the side surfaces substantially in grazing incidence (i.e., at angles to the side surface which are smaller than 45 °). This leads to a high reflectivity, so that the disc acts as a kind of optical waveguide.

The underlying object of the invention, the transparent balustrade such that the transparent balustrade can be illuminated by a lighting device and at the same time a simple replacement of the lighting device is possible is also solved by a passenger transport device comprising an endless conveyor belt, an endless handrail and a transparent balustrade , The balustrade is arranged laterally from the conveyor belt and comprises at least a first transparent disc, which supports the handrail. In this case, the first transparent pane has a structuring for coupling out illumination radiation from the first transparent pane. Furthermore, the transparent balustrade comprises a separately mountable lighting device which is connected to the first transparent pane. In contrast to the prior art, such lighting devices can be replaced without dismantling the handrail or even the entire balustrade is required.

The structuring of the first transparent pane, just as in the described structuring of the second transparent pane, leads to special lighting effects for the external viewer. The structuring can be achieved for example by means of sand blasting or by acid treatment. Particularly preferably, the structuring comprises an outer engraving, which has been produced for example by means of laser engraving. Illumination radiation impinging on the structuring is scattered at the structuring and thus decoupled from the pane.

Preferably, the passenger transport device is further configured such that the first transparent pane has at least one coupling-in region, at which the illumination radiation generated by the lighting device is coupled into the first transparent pane. This allows a well-defined entry of the illumination radiation into the first transparent pane. This coupling region is arranged, in particular, on the front side adjacent to the handrail and / or on the end side of the first transparent pane opposite the handrail. The arrangement on an end face has the advantage that the coupled illumination light automatically strikes the side surfaces substantially in grazing incidence (i.e., at angles to the side surface which are smaller than 45 °). This leads to a high reflectivity, so that the disc acts as a kind of optical waveguide.

Alternatively, the coupling-in region can also be arranged on a side surface of the first transparent pane. This has the advantage that the lighting device for assembly and for any replacement is easier to achieve.

In all embodiments, it is advantageous if the coupling-in area is polished or provided with an antireflection coating. As a result, a particularly efficient coupling of the illumination radiation is achieved.

In some of the embodiments described, it may happen that the first transparent pane and / or the second transparent pane (if present) are partially provided with an opaque trim. In these cases, a reflective layer is advantageously arranged at least in regions between the non-transparent lining and the adjacent transparent pane. This causes the proportion of illumination radiation emerging from the disc to be reduced at these points. As a result, absorption of the emerging illumination radiation can be suppressed by the non-transparent cladding. Thus, a larger part of the illumination radiation is available for the illumination of the transparent balustrade.

Particularly preferably, the described illumination devices comprise a plurality of LEDs. The use of LEDs has the advantage that a high light output can be achieved by a low energy input. Furthermore, LEDs are so miniaturized that the lighting devices can be gracefully executed and thus do not affect the appearance of the balustrade. In addition, only a small proportion of waste heat is generated, so that no excessive cooling elements must be provided.

In the embodiments with a first transparent pane and a second transparent pane, it is also possible to provide both panes with a structuring for coupling out illumination radiation. In this way, even with the use of surface structuring methods, three-dimensional effects can be produced by applying different structurings to the surfaces of the various panes. For the beholder, the luminous structures then lie in different depths of the balustrade.

The invention will be described in more detail with reference to the figures. Hereby show:

1 a passenger transport device in a side view;

2 a first embodiment of the Glasbalustrade invention;

3 a second embodiment of the Glasbalustrade invention.

In 1 is a side view of a passenger transport device 1 shown. It is in this case an escalator. However, the invention can also be designed as a horizontal or oblique treadmill. The passenger transport device comprises an endless conveyor belt 3 and an endless handrail 5 , Side of the conveyor belt 3 is a transparent balustrade 7 arranged. The transparent balustrade 7 includes a first transparent pane 9 that the handrail 5 supported. To do this, put on the transparent disc 9 a profile 11 on that the handrail 5 during operation of the passenger transport facility 1 leads. The handrail is driven by means of the drive 13 , which is below the conveyor belt 3 is arranged. Around the transparent balustrade 7 to illuminate, is also below the conveyor belt 3 an energy source 15 intended.

2 shows a first embodiment of a Glasbalustrade invention 7 , It is in the right part of 2 a side view of a detail of the transparent balustrade 7 shown and in the left part of the 2 a section through the transparent balustrade 7 along the line AA.

The transparent balustrade 7 includes a first transparent pane 9 , This is in the lower part with brackets 17 attached. The first transparent pane may comprise a glass pane, in particular made of safety glass, or else a plastic pane. In the upper area sets a U-shaped profile 11 on the first transparent pane 9 on. This profile 9 leads the handrail 5 during operation of the passenger transport facility 1 , The first transparent pane 9 thus supports the handrail 5 from. Furthermore, the transparent balustrade comprises lighting devices 19a and 19b , The lighting device 19a is below the profile 11 laterally with the first transparent pane 9 connected. This connection can be made, for example, by screwing with the first transparent pane 9 or by means of an adhesive connection to the transparent pane 9 be formed. Alternatively, it is also possible, the lighting device 19a on the profile 11 to attach and in this way with the disc 9 connect to. To ensure interchangeability, it is important that the lighting device 19a can be mounted separately and thus independent of profile 11 can be assembled and disassembled.

The lighting device 19a includes an enclosure 21 and a light source 23 , The light source is preferably a plurality of LEDs (Light Emitting Diodes). Adjacent to the illumination device 19a has the first transparent pane 9 a coupling area 25 on which the illumination radiation generated by the illumination device 27 in the first transparent pane 9 is coupled. At the lighting device 19a is the coupling area 25 arranged on the side surface of the first transparent pane. In order to increase the efficiency of the coupling, the coupling-in region is preferably polished. Alternatively, the coupling-in region can also be provided with an antireflection coating (for example in the form of an adhesive film).

The coupled illumination radiation 27 propagates now within the transparent pane 9 , When the illumination radiation hits 27 on the interfaces of the disc 9 At least part of the illumination radiation is returned to the disc 9 reflected. Only a minor part of the illumination radiation occurs when the illumination radiation hits 27 on the interfaces of the disc 9 thus illuminating the transparent balustrade 7 , Optionally, this division into reflected and transmitted portion of the illumination radiation 27 specifically by a surface coating of the first transparent pane 9 set. In the places where the first transparent pane 9 is anyway provided with an opaque cladding, at least partially a reflective layer between the non-transparent cladding and the adjacent disc 29 arranged. This is applied, for example, in the form of a reflective adhesive film. This causes the proportion of illumination radiation 27 which exits the disc, is reduced at these points. As a result, an absorption of the exiting illumination radiation 27 be suppressed by the non-transparent cladding. So it is a major part of the illumination radiation for the illumination of the transparent balustrade 7 to disposal. Examples of the non-transparent cladding are in particular the profile 11 and the brackets 17 ,

In order to create special lighting effects in addition to the basic illumination, the first transparent pane is visible 9 a structuring 31 for coupling out of illumination radiation 27 on. The structuring 31 can be achieved, for example, by sandblasting or by acid treatment. Particularly preferably, the structuring comprises 31 an exterior engraving made by laser engraving. On the structuring 31 incident illumination radiation 27 will be at the structuring 31 scattered and thus out of the disk 9 decoupled. As a result of the scattering, the angles of incidence change to the interfaces of the first transparent pane, so that the scattered illuminating radiation 27 mostly not in the first transparent pane 9 is reflected back, but from the first transparent pane 9 exit. Thus, for observers on both sides of the transparent balustrade arise 7 brightly lit areas on the first transparent pane 9 that the form of structuring 31 exhibit. For example, the areas may be in the form of characters or logos. Alternatively, abstract patterns and embellishments can be highlighted.

Alternatively or additionally, the transparent balustrade 7 a lighting device 19b on, which is also an enclosure 21 and a light source 23 includes. In contrast to the lighting device 19a is the lighting device 19b in the lower part of the transparent balustrade 7 between the brackets 17 arranged. The lighting device 19b is with the lower face of the first transparent disc 9 connected. For this purpose, the lighting device 19b for example, with the first transparent pane 9 screwed or glued. Alternatively, the lighting device 19b also about the brackets 17 with the disc 9 be connected. To ensure interchangeability, it is important that the lighting device 19b can be mounted separately and thus independent of the brackets 17 can be assembled and disassembled. Adjacent to the illumination device 19b has the first transparent pane 9 also a coupling area 25 on which the illumination radiation generated by the illumination device 27 in the first transparent pane 9 is coupled. In order to increase the efficiency of the coupling, the coupling-in region is preferably polished. Alternatively, the coupling-in region can also be provided with an antireflection coating (for example in the form of an adhesive film).

3 shows a further embodiment of a Glasbalustrade invention 7 , It is in the right part of 3 a side view of a detail of the transparent balustrade 7 shown and in the left part of the 3 a section through the transparent balustrade 7 along the line BB.

The transparent balustrade 7 includes a first transparent pane 9 , This is in the lower part with brackets 17 attached. The transparent pane may comprise a glass pane, in particular made of safety glass, or else a plastic pane. In the upper area sets a U-shaped profile 11 on the first transparent pane 9 on. This profile 9 leads the handrail 5 during operation of the passenger transport facility. The first transparent pane 9 thus supports the handrail 5 from. Furthermore, the transparent balustrade includes 7 a second transparent pane 33 , the first transparent pane 9 is set. In the present case is the second transparent pane 33 with the first transparent pane 9 firmly connected by lamination. Alternatively, the discs can also be glued. It is also possible the second transparent disc 33 with the help of a mechanical holder with the first transparent disc 9 to connect or keep separate. Optionally, a gap is arranged between the first transparent pane and the second transparent pane. Preferably, however, the two discs are flush with each other to prevent unwanted reflections.

The first transparent pane 9 and the second transparent disc 33 may comprise a glass pane, in particular made of safety glass, or even a plastic pane. In a particularly preferred embodiment, the first transparent pane has a safety glass and the second transparent pane 33 a simple float glass. The advantages of this variant will be explained later in relation to the structuring.

Furthermore, the transparent balustrade comprises lighting devices 35a and 35b , Also possible are variants in which only one of the lighting devices 35a or 35b is available.

The lighting device 35a is below the profile 11 with the second transparent pane 33 connected. This connection can be made for example by a screwed or glued connection to the first transparent pane 9 or to the second transparent pane 33 be formed. Alternatively, it is also possible, the lighting device 35a on the profile 11 attach and in this way with the second transparent pane 35a connect to. To ensure interchangeability, it is important that the lighting device 35a can be mounted separately and thus independent of profile 11 can be assembled and disassembled.

The lighting device 35a includes an enclosure 21 and a light source 23 , The light source is preferably a plurality of LEDs (Light Emitting Diodes). Adjacent to the illumination device 35a has the second transparent pane 33 a coupling area 25 on which the illumination radiation generated by the illumination device 27 in the first transparent pane 9 is coupled. To increase the efficiency of the coupling, the coupling-in area 25 preferably polished. Alternatively, the coupling-in area 25 also be provided with an antireflection coating (eg in the form of an adhesive film).

The lighting device 35a is so with the second transparent pane 33 connected to that the coupling-in area 25 at the handrail 5 adjacent end side of the second transparent pane 33 is arranged. This allows a particularly slim design of the transparent balustrade 7 ,

The analog lighting device 35b is arranged so that the associated coupling area 25 on the opposite side of the handrail of the second transparent disc 33 lies.

Alternatively, the lighting devices 35a and 36b be arranged so that the coupling region 25 on a side surface of the second transparent disc comes to rest, such as in the lighting device 19a the first embodiment.

To the two lighting devices 35a and 35b To protect against external influences, these are with covers 37 Mistake.

The coupled illumination radiation 27 now propagates within the second transparent pane 33 and the first transparent pane 9 , When the illumination radiation hits 27 on the interfaces of the second transparent disc 33 or the first transparent pane at least a portion of the illumination radiation back into the first or second transparent pane 9 . 33 reflected. Only a minor portion of the illumination radiation impinges upon impacting an outer surface of the transparent balustrade 7 and illuminates the transparent balustrade 7 , Optionally, this division into reflected and transmitted portion of the illumination radiation 27 specifically by a surface coating of the first transparent pane 9 and / or the second transparent pane 33 set. In the places where the first transparent pane 9 or second transparent pane 33 is anyway provided with an opaque cladding, at least partially a reflective layer between the non-transparent cladding and the adjacent disc 29 arranged. This is applied, for example, in the form of a reflective adhesive film. This causes the proportion of illumination radiation 27 which exits the disc, is reduced at these points. As a result, an absorption of the exiting illumination radiation 27 be suppressed by the non-transparent cladding. So it is a major part of the illumination radiation for the illumination of the transparent balustrade 7 to disposal. Examples of the non-transparent cladding are in particular the profile 11 , the brackets 17 and the covers 37 ,

In order to effect special lighting effects in addition to the basic illumination, the second transparent pane has 33 a structuring 31 for coupling out of illumination radiation 27 on. The structuring 31 can be achieved, for example, by sandblasting or by acid treatment. Particularly preferably, the structuring comprises 31 an exterior engraving made by laser engraving. On the structuring 31 incident illumination radiation 27 will be at the structuring 31 scattered and thus from the slices 9 and 33 decoupled. As a result of the scattering, the angles of incidence on the boundary surfaces of the disks change 9 and 33 so that the scattered illumination radiation 27 mostly not in the panes 9 and 33 is reflected back, but from the slices 9 and 33 exit. Thus, for observers on both sides of the transparent balustrade arise 7 brightly lit areas on the disc, showing the shape of the structuring 31 exhibit. For example, the areas may be in the form of characters or logos. Alternatively, abstract patterns and embellishments can be highlighted.

At the in 3 illustrated embodiment, the first transparent disc 9 and the second transparent disc 33 different types of glass. The first transparent pane 9 has a safety glass and the second transparent pane 33 a simple float glass. This combination allows for a stable transparent balustrade 7 because the safety glass for the handrail 5 supporting first transparent pane 9 is particularly stable and withstands enormous loads. On the other hand allows the superior second transparent disc 33 from simple float glass, the introduction of structuring 31 inside the second transparent pane 33 , Such structuring 33 inside the second transparent pane 33 can be made for example with laser engraving. An appropriate interior engraving of safety glass is not possible. Safety glass is thermally treated during production, so that a tension builds up in the material. When attempting an interior engraving, these stresses lead to the shattering of the safety glass.

However, interior engravings have the advantage that three-dimensional structures can also be incorporated into glass, resulting in a wider range of creative possibilities. The combination of the two types of glass therefore allows the advantages of safety glass to be retained while at the same time opening up new creative possibilities.
