Definitions

  • the invention relates to a gate system adapted to control passenger access to a passenger moving system said moving system having a reversible travelling direction; a passenger moving system comprising such a gate system; and a method for controlling passenger access to a passenger moving system.
  • Barriers positioned about the entrance of a passenger moving system are commonly used to control and regulate passenger flow when entering said moving system. More particularly, they are positioned at the entrance to prevent shopping and/or baggage trolleys from entering the moving system thereby mitigating a serious safety risk.
  • Passenger moving systems preferably comprise moving walks and escalators.
  • a fixed barrier positioned at the entrance of an escalator or moving walk allows passengers to pass through a first landing area to travel on the escalator or moving walk whilst obstructing trolleys from doing the same. Having reached a second landing area, the passenger exits the system.
  • an unrestricted area is available to accommodate passengers exiting the escalator or moving walk. In this area, a barrier installation is not permitted.
  • the travelling direction cannot be changed, thus the entrance and exit area of the escalator or moving walk never changes nor does the position of the barrier.
  • An escalator or moving walk having an alternating direction of travel requires a barrier at the relevant entrance area.
  • a fixed barrier is not suitable in this situation thus a removable barrier is used.
  • the removable barrier must be located according to the entrance area matching the travelling direction of the escalator or moving walk. This is cumbersome and requires a significant amount of "manpower" in removing a barrier at one end of an escalator or moving walk and relocating it another end when the direction of travel is changed.
  • there are specific requirements in the regulations EN 115-1:2017 pertaining to how a removable barrier is to be placed thus if a removable barrier is positioned incorrectly during relocation, the escalator or moving walk will not pass a safety inspection. In some escalators or moving walks, it may not even be possible to reposition a barrier in a way that complies with regulations.
  • a further disadvantage associated with removable barriers is that a time lag exists between the opening and/or the closing of the relevant barrier or barriers at an exit or an entrance of an escalator or moving walk. This can pose a safety risk since in the time it takes to change the travelling direction of the escalator or moving walk and re-position the barrier or barriers accordingly, a passenger with a trolley could enter the escalator or moving walk during this transition period, thereby jeopardizing their safety as well as the safety of other passengers on the escalator or moving walk.
  • EP 2778337 A1 A recently developed removable barrier is disclosed in EP 2778337 A1 .
  • This barrier is designed to be operated manually or remotely to control access to an escalator or moving walk or a similar installation wherein when the barrier is in a "closed” position, an emergency passage is permitted via retraction of the "closed” position by applying an abnormal force to it.
  • Another barrier system is disclosed in EP 510522 A2 wherein the system is adapted to permit entrance to a passenger moving system of a specific type of trolley and to prevent all other trolley types from entering the passenger moving system.
  • inventive gate system a passenger moving system comprising the inventive gate system and a method for controlling passenger access to a passenger moving system, are the subject of the appended claims and are described in further detail in the following embodiments and figure description.

  • the inventive gate system comprises:
  • the interface device can be adapted to replace the control center of the gate system (option A).
  • the control unit may be adapted to be more "intelligent".
  • the control unit can undertake the task to execute the characteristics of the control center thus providing for any necessary connections (e.g., via electrical, wireless or other means) and thereby allowing for control of the gate system, in particular, the barrier or barriers.
  • the interface device can also be employed as an auxiliary to the control center (option B), or to both the control unit and the control center (option C). This would preferably depend on the requirements of the passenger moving system and the gate system.
  • the barrier or barriers at the first landing area has a different position to the barrier or barriers at the second landing area.
  • each barrier is adapted to alternate between the first and second position according to the travelling direction of the passenger moving system.
  • alternation occurs, preferably automatically via cooperation between the control unit and the control center.
  • alternation occurs, preferably automatically, via cooperation between the control unit and the interface device.
  • alternation occurs, preferably automatically, via co-operation between the control unit, the control center and the interface device.
  • control center and optionally the interface device preferably comprise
  • the rotating element is preferably adjustable in height or in length, or both. This advantageously accommodates various safety requirements for various passenger moving systems.
  • the first position preferably relates to the barrier being configured preferably via rotation, to provide an unrestricted exit for a passenger when disembarking from the passenger moving system.
  • the gate system is described as "open”. This advantageously ensures that only passengers who are permitted to travel on a passenger moving system can embark and disembark such a moving system, thus improving passenger safety.
  • the second position preferably relates to the barrier being configured, preferably via rotation, to block access to the passenger moving system of a prohibited passenger, and permit access to a passenger, wherein a prohibited passenger preferably relates to a passenger pushing a trolley or a pram or a passenger in possession of other non-permitted items on a passenger moving system. In such a configuration, the gate system is described as "closed”.
  • each post comprises a first trigger and a second trigger, wherein the second trigger is preferably at a different location to the first trigger.
  • Each rotating element preferably comprises an activator for activating the first trigger or the second trigger.
  • Two triggers are preferred to ensure a stronger signal. This advantageously provides that each individual post, in particular the barrier is controllable.
  • a preferred form of trigger includes sensor devices, e.g., magnetic sensors; IR sensors; light sensors; heat sensors; mechanical switches, e.g., safety switches.
  • the barrier is preferably adapted to be
  • each post When the first trigger has the logic state of 0 and the second trigger has the logic state of 0, this is interpreted as a "barrier error” and no movement of the barrier 12 occurs. When the first trigger has the logic state of 1 and the second trigger has the logic state of 1, this is interpreted as a "barrier error” and no movement of the barrier 12 occurs. When either the first or second trigger is faulty, this is also interpreted as a "barrier error”.
  • This logic applies to each post within the gate system. For example, when the inventive gate system comprises a first post positioned at the first landing area and a second post positioned at the second landing area, each post operates according to this logic system.
  • each post within each pair of posts operates according to this logic system.
  • activation occurs upon alignment of the trigger with the activator.
  • alignment occurs via a rotation of the rotation element upon an instruction signal transmitted via the control center and the control unit, or upon an instruction signal transmitted via the interface device and the control unit, or upon an instruction signal transmitted via the interface device, control center and the control unit.
  • alignment occurs in the vertical plane. This advantageously ensures that each individual post can be independently operated.

  • the elevated surface comprises other devices normally installed in an escalator or a moving walk which can be used as key switches or activators, for example; speakers (to transmit audio signals).
  • switches or activators are also activated upon a vertical upwards rotation of the barrier. This advantageously allows for an easier management of an escalator or a moving due to the location of such devices.

  • the rolling element 1421 is released thus activating the second mechanical switch and giving it the logic state of 1.
  • the barrier 12 and consequently the indent 140 is no longer aligned with the first mechanical switch 141 and it deactivates.
  • the first rolling element 1411 rests under pressure upon the outer surface of the rotating element 111 and the first mechanical switch has the logic state of 0.
  • This logic state configuration (0, 1) represents the barrier in the "closed" position.
  • inventive gate system can also comprise a single post at each end.
