Definitions
- the present disclosure generally relates to a passenger conveyor for transporting passengers and/or goods comprising a frame receiving a moving staircase comprising a number of steps or receiving a moving walk comprising a number of pallets, wherein a skirt extending above the steps or pallets is formed on or connected to the frame on at least one side of the staircase or moving walk, wherein the skirt comprises at least one recess having an opening on an inner side of the skirt, and wherein the opening of the recess is covered by a skirt cover panel.
- the present disclosure further relates to a skirt cover panel for such a passenger conveyor and a method to manufacture the same.
- Such passenger conveyors which are moving staircases or walks for carrying people and/or goods e.g. between floors or along a floor of a building or structure, are well known from the state of the art and typically comprise transition areas at their ends and a transportation area in between the transition areas. Steps or pallets of the passenger conveyor are running through those areas, forming stairs or a walk on an upper side of the transportation area and are turned around in the transition areas. The steps or pallets are typically guided on rails by a chain and/or rollers. Usually, all components of the conveyor are mounted in or on a frame.
- skirts extend upwards above the steps or pallets limiting the passenger area in side direction and on top of the skirt, balustrades extend to avoid the passengers from falling of the conveyor.
- These skirts may house lighting means, e.g. for design reasons and/or to provide lighting of the staircase or walk, and may also house sensor elements, e.g. for detecting a person or good entering or leaving the staircase or walk.
- skirts are of complicated construction when housing several components like lighting and sensor elements at the same time.
- the different components require separate housing with separate covers at an inner side of the skirt, wherein each cover is designs for the specific optical needs of the component.
- a passenger conveyor for transporting passengers and/or goods comprising a frame receiving a moving staircase comprising a number of steps or receiving a moving walk comprising a number of pallets, wherein a skirt extending above the steps or pallets is formed on or connected to the frame on at least one side of the staircase or moving walk, wherein the skirt comprises at least one recess having an opening on an inner side of the skirt, wherein the opening of the recess is covered by a skirt cover panel, wherein the skirt cover panel is formed from at least a first material and a second material;, and wherein the first material and the second material are integrally connected to each other and are forming a continuous panel with each other.
- first element As far as elements are designated with the aid of numbering, for example "first element”, “second element” and “third element”, this numbering is provided purely for differentiation in the designation and does not represent any dependence of the elements on one another or any mandatory sequence of the elements.
- the device or method may have a "first element”, as well as a “third element”, but without necessarily having a “second element”.
- a passenger conveyor generally refers to a device for transporting people or goods from one area to another area of a building, structure, or public area or vice versa.
- a passenger conveyor is an escalator having steps forming the staircase, wherein the areas are on different height levels or the passenger conveyor is a moving walk having pallets forming the walk, wherein the areas are on different or the same height levels.
- Such passenger conveyors are used e.g. in highly frequented buildings like office buildings, administration buildings or in public transport, e.g. at a subway station.
- a passenger conveyor has a first transition area at a first end, a second transition area at a second end and a transportation area in between the first transition area and the second transition area.
- the steps or pallets of the passenger conveyor are running through those areas, form a staircase or walk on an upper side of the transportation area, in case of an escalator are transformed into a flat arrangement with each other in the transition areas and are turned around in the transition areas.
- a frame which is the basic load-bearing element of the passenger conveyor, is preferably formed by opposing side units and cross members (also referred to as transverse beams) connecting them, a respective side unit being formed by at least one side wall and, in particular, by an upper beam and/or a lower beam.
- the frame can also include a floor unit connected to the side units, wherein such a floor unit does not necessarily have to fulfill a load-bearing function, but is designed, for example, with regard to the function of collecting and, if necessary, draining off oil from a drive, or is optimized with regard to covering and/or accessing the passenger conveyors structure and/or components thereof.
- a skirt is understood to extend upwards from the side unit, in particular from the beam and may cover a part of the frame structure or structure elements of a balustrade to an inner side of the conveyor in an area above the steps or pallets.
- An inner side of the skirt is understood to be a side facing the steps or pallets.
- Such a skirt also serves to protect the frame or any other components against the intrusion of objects and/or persons. Since the skirt is arranged in a fixed position directly next to the steps or pallets, is as close as possible to the steps/pallets and is also in the immediate vicinity of a person standing on the guideway device, the skirt is required not to have any potential danger points such as unevenness, open recesses, edges, ridges or the like. Therefore, the skirt cover panel preferably forms an even surface with the skirt respectively forms an even surface of the skirt.
- the skirt cover panel is received in a receptacle at the recess, e.g. a groove extending along an edge of the recess or is clamped or otherwise form fitted in the recess.

- Such a signal may be an infrared signal or may be of any other kind that can penetrate an according second material, such as an ultrasonic signal.
- the sensor element is a photocell, which is activated when an according (infrared) light signal falls on a cell surface.
- a photocell may interact with a sensor element for emitting such a light signal, which may be located on a opposite skirt of the passenger conveyor.
- the photocell and the light emitting element may both be received in a respective recess at opposite skirts of the passenger conveyor, wherein both recesses may be formed and covered according to the invention.
- the passenger passing the sensor elements e.g. by entering or leaving the passenger conveyor, is then detected due to interrupting the light signal.
- the recess is formed as a channel extending parallel to the movement direction of the steps or pallets, in particular the recess is formed by a profile.
