Definitions

  • HANDRAIL SYSTEM FOR A PASSENGER TRANSPORTATION DEVICE, COMPRISING AT LEAST ONE ELECTRIC FIELD GENERATION DEVICE AND AT LEAST ONE ELECTRIC FIELD DETECTION DEVICE, AND METHOD FOR CONTROLLING THE HANDRAIL SYSTEM
  • the present invention relates to a handrail system for a passenger transport device, in particular an escalator or a moving walkway.
  • the present invention relates to a passenger transport device, in particular an escalator or a moving walkway.
  • the present invention relates to a method for controlling a handrail system for a passenger transport device, in particular an escalator or a moving walkway.
  • the present invention relates to a method for controlling a passenger transport device, in particular an escalator or a moving walk.
  • An escalator is a means of transporting people 25 to cover a distance. If a height distance is overcome, steps are formed in the device by moving segments, for example metal segments.
  • Escalators are primarily known from public facilities with high levels of public traffic, such as department stores, train stations and airports. Although they have a slower conveying speed than elevators, for example, they offer the advantage that they can accommodate significantly more people.
  • moving walkways 2 can be designed in a horizontal or inclined design.
  • the surface of a moving walkway can also be inclined and/or curved.
  • escalators and moving walks The purpose of escalators and moving walks is to transport one or more people at a higher speed than walking speed and/or with less muscle power.
  • An accelerated "transport" of people from or to a location can, for example, save time and space.
  • a handrail is therefore an essential component for the safety of escalators and moving walks.
  • Handrails are typically located on a balustrade located on one or both sides of the escalator or moving walk.
  • a handrail is run along this balustrade, usually at the top of the balustrade, at the same speed as the escalator or moving walk is moving.
  • the handrail offers a secure grip in a position that is comfortable and easily accessible for the passenger.
  • An ordinary escalator requires an average of 2-5 kW of electrical power. The need depends on the speed and the length of the stairs. The power consumption increases only slightly due to the load of people. To avoid idle times, more modern systems have sensors, for example in the form of radar sensors, footplates or light sensors.
  • Such systems can be equipped with a time switch logic. If the sensors have not been triggered for a while and there are probably no longer any people on the escalator, the electronics turn it off and only start up again when a person triggers the sensor. Newer passenger transport devices are often no longer switched off completely, but continue to be operated at a greatly reduced speed. Power consumption and wear and tear are reduced less than with switching off, but approaching passengers can be signaled in this way that they are ready for operation and the direction of travel, and also a 3
  • radar sensors are installed in the end areas of the escalator, i. H. installed at the beginning and end of escalators and moving walks, as well as numerous light sensors in the area of the step band.
  • the use of a combination of radar and light sensors is also prescribed by DIN EN 115-1:2018-01.
  • the high number of sensors used is a significant cost factor and also increases the maintenance intensity of escalators.
  • Radar sensors are usually installed in the balustrade. Balustrades often contain or consist of metal, which significantly limits the function of the radar sensors. Recesses in the balustrade are therefore necessary for radar sensors installed in this way in order to ensure the function of the radar sensor at all.
  • a major disadvantage is that the detection range of the radar sensors in the recesses is severely restricted.
  • Radar sensors are usually arranged in the end areas of the escalators and moving walks below the handrail in the floor area.
  • the radar sensors are usually covered with an optical cover that does not have any metal.
  • These optical panels are referred to as a "dome”. These panels are often designed as a projection on the balustrade and thus offer a safety risk for passengers, especially children, since they represent an increased potential for injury.
  • the object is that a safer passenger transport system is provided and that the aforementioned disadvantages are overcome.
  • the object is accordingly achieved by a handrail system for a passenger transport device, in particular an escalator or a moving walkway.

  • the object is also achieved by a passenger transport device having at least one step band, at least one handrail system, and at least one balustrade.
  • the at least one handrail system is connected to the at least one balustrade via the guide device, with the control device being configured to output a control signal for actuating the guide device to move the step band in the longitudinal direction of the handrail when the electric field detection device detects a change in the electric field detecting the approach of a person.
  • the object is also achieved by a balustrade with the handrail system, the handrail system being connected to the balustrade via the guide device.
  • the object is also achieved by a method for controlling a handrail system for a passenger transport device, in particular an escalator or a moving walkway.

Component X only obtains its full functionality through one or more parts of component Y. Conversely, component Y obtains its complete functionality from one or more parts of component X. It is also conceivable that only one of the two components obtains its full functionality from the other component.

Abstract

La présente invention concerne un système de main courante (12) pour un dispositif de transport de passagers (10), comprenant une main courante (14), un dispositif de guidage (18) destiné à guider de manière mobile la main courante (14) dans une direction longitudinale de la main courante, un dispositif de génération de champ électrique destiné à générer un champ électromagnétique pour détecter une personne qui s'approche du dispositif de génération de champ électrique, un dispositif de détection de champ électrique destiné à détecter un changement dans le champ électromagnétique généré par le dispositif de génération de champ électrique, provoqué par l'approche d'une personne, et pour délivrer en sortie un signal de confirmation à un dispositif de commande, et le dispositif de commande destiné à délivrer en sortie un signal de commande pour déclencher le dispositif de guidage (18) en vue de déplacer la main courante (14) dans la direction longitudinale de la main courante lorsque le dispositif de détection de champ électrique a détecté un changement dans le champ électrique, provoqué par l'approche d'une personne, et le dispositif de commande a reçu un signal de confirmation provenant du dispositif de détection de champ électrique. La présente invention concerne également une balustrade (16) équipée d'un système de main courante (12), un dispositif de transport de passagers (10) équipé d'un système de main courante (12), et un procédé de commande d'un système de main courante (12) et/ou d'un dispositif de transport de passagers (10).
