Definitions

  • the invention relates to moving walking systems, also known as moving walkways, such as those used in all manner of large-scale premises, for example, in airports and/or stations in which there is an aim to facilitate passenger movement.
  • the invention refers to a moving walking system comprising at least one walking platform, at least a first and second handrail and a bridging system comprising at least one moveable part and at least one fixed part, wherein the bridging system is positioned in the vicinity of the handrail and is capable of affecting the operation of the moving walking system.
  • EP 0 837 026 A1 discloses a handrail mechanism for a moving sidewalk, wherein the handrail includes a plurality of independent moving handrail portions. All portions are arranged without overlapping with one another, each being driven at a speed close to the driving speed of nearby treadboards.
  • a plurality of bridging systems are disposed at jointing portions between adjoining moving handrail portions to guide passenger hands from one moving handrail portion to the next.
  • An electric indicator is provided in the vicinity of the bridging system to alert passengers of its existence. This system attempts to alert passengers and users of the handrail system to any upcoming changes or variations in speed along the handrail path.
  • the inventive walking system comprises at least one walking platform comprising a plurality of pallets and a handrail system with at least two handrails in single line configuration, particularly without overlapping with one another.
  • a first handrail of the at least two handrails comprises a first end and a second end.
  • a second handrail of the at least two handrails also comprises a first end and a second end.
  • the inventive walking system also comprises a bridging system, wherein said bridging system forms a bridge between the second end of the first handrail and the first end of the second handrail.
  • the bridging system of the inventive walking system comprises a movable part and a fixed part. The movable part and the fixed part are themselves contactable to form the bridge between the first handrail and the second handrail.
  • the movable part is arranged in front of the fixed part with respect to a moving direction of the handrail system.
  • the movable part is adapted to work as an anti-trap protection for users of the handrail system. Without the movable part, entrapment, e.g. of a user's hand or the user's clothes may occur when a user's hand or a piece of clothing becomes stuck between the handrail and the bridging system at the entry of the belt into the bridging system. When this happens, the handrail belt does not stop and continues to operate as normal. Such entrapment can advantageously be prevented according to the invention by the movable part of the handrail system.
  • the anti-trap protection is advantageously achieved by moving the movable part out of the entrapment zone, i.e., the area where entrapment may occur, especially the area where the handrail belt enters the bridging system.
  • the movable part is rotatably moved out of said zone when a force, which exceeds a predetermined threshold, e.g. the force from a user's hand or a piece of clothing upon becoming stuck between the handrail belt and the moving part, is applied to the movable part in the direction of the moving direction of the moving part.
  • the threshold can particularly be defined as a value between 1 N and 20 N, preferably between 5 N and 12 N (N: Newton).
  • the moving direction of the movable part preferably follows the guidance of the handrail belt.
  • the gap is smaller than 3 mm, preferably the gap is smaller than 1 mm (mm: Millimeter). It is also preferred that the movable part and the handrail belt of the walking system do not contact each other since this would increase the friction within the system.
  • the walking system according to the invention has at least the advantage over the prior art in that it allows several handrails in a single line configuration to be easily connected. It also provides for improved passenger safety through the presence of the movable part, which advantageously helps to protect users or their clothes from entrapment when the handrail or the handrail belt respectively enters into the bridging system.
  • the moveable part is mounted to the first handrail at the second end of the first handrail and the fixed part is to the second handrail at the first end of the second handrail.
  • the movable part of the bridging system is adapted to move along a guiding surface of the fixed part when a force, particularly a force which exceeds a predetermined threshold, is applied on the movable part in the direction of the moving direction of the moving part.
  • the guiding surface is essentially parallel to the belt of the first handrail covered by the bridging system. This provides for a smooth operation of parts of the bridging system, thus augmenting its lifespan and reducing maintenance costs.
  • the resulting freed space advantageously prevents user entrapment.
  • the movable part is configured or mounted, respectively, in such a way that it is moved, preferably rotatably moved with the same speed as the driven handrail belt.
  • the movable part is moved, preferably rotatably moved, faster than the driven handrail, particularly at least 1,5 times faster than the driven handrail. This advantageously further reduces the risk of entrapment.
  • the movable part of the bridging system is adapted to move, preferably rotatably move, as a single part when a force, particularly a force which exceeds a predetermined threshold, is applied to the movable part in the direction of the moving direction of the moving part.
  • a force particularly a force which exceeds a predetermined threshold
  • the movable part of the bridging system is adapted to move as a single part, this particularly means that the whole movable part is moved, preferably rotatably moved, relative to the fixed part.
  • the lower part of the movable part is at least partially covered by housing, preferably at the lower sides of the movable part in order to prevent entrapment or injury by the movable part.
  • the movable part of said bridging system can comprise several parts wherein the movable part is adapted to move, preferably rotatably move, as several parts when a force, particularly a force which exceeds a predetermined threshold, is applied on the movable part in the direction of the moving direction of the moving part.
  • the movable part comprises a lower fixed part and at least one movable part, wherein said at least one movable part moves towards the fixed part if a force, particularly a force which exceeds a predetermined threshold, acts on the movable part.
  • the movable part is collapsible, preferably in an accordion manner or in a telescopic manner.
  • the walking system according to the invention can advantageously comprise a further system, wherein said further system is adapted to guide a handrail, in particular, a handrail belt.
  • Said further system can comprise for example a balustrade, at least one friction wheel, or any other support mechanism which supports the handrail, preferably the handrail belt.
  • the further system supports the handrail/handrail belt at the newel.
  • the movable part of the bridging system can be mounted to the further system.
  • the movable part of the bridging system may also be in communication with the pallets of the moving walking system.
  • the term communication as used herein and throughout can refer to physical communication, i.e., in actual physical contact, or electronic communication, i.e., not in physical contact, but electronically contacted, or both, i.e., physically contacted and in electronic communication.
  • a first handrail of the walking system according to the invention comprising a handrail belt, is preferably comprised within the further system, preferably within a first balustrade and a second handrail comprising a handrail belt, is preferably comprised within a second balustrade.
  • One balustrade can also comprise at least both a first and second handrail.
  • the bridging system can also comprise a sensor which is adapted to sense any movement of the moveable part. This can be achieved by applying a force to the movable part, preferably, the movable part acts on the sensor when moving.
  • the walking system comprises a control unit for controlling the movement of the pallets, wherein the sensor is in communication with the control unit of the walking system.
  • the moving walking system comprises at least one control unit for controlling the moving walking system, wherein the sensor is in communication with the control unit, and wherein the control unit is adapted to stop the moving walking system if the sensor detects a movement, preferably a rotatable movement, of the movable part.
  • the control unit can instruct at least a part or section of the moving walking system to stop, particularly the handrail of the moving walking system. Preferably this is at the section of moving walkway where the movable part has been activated. It is also preferred that when the sensor is activated, the pallets decelerate before stopping therefore avoiding any possible injury which could be caused to users by a sudden stop of the walking platform.
  • the movable part of the bridging system works against a spring tension system when it is moved, preferably rotatably moved, by a force applied thereto, wherein said force exceeds a predetermined threshold.
  • the movable part can also work against a roller system, wherein said rollers are preferably positioned between the movable part and the fixed part and can be in communication with a sensor and/or control unit of the moving walking system.
  • the movable part does not decompress at normal touch, i.e., when a passenger is holding onto the handrail. This advantageously controls the sensitivity of the movable part and prevents the handrail and walking system from being accidentally stopped and started.
  • a force may be provided via a human hand, elbow, or any body part that may be in contact with a handrail which is sufficient to cause the movable part to move, preferably rotatably move, and preferably activate the sensor and consequently the control unit.
  • any object e.g., item of clothing, which can come into contact with the handrail, together with a force, can also be capable of causing the movable part to move, preferably rotatably move, and thus activate the sensor.
  • the movable part is adapted to be moved back to its initial position when a force is no longer applied to the movable part in the moving direction of the movable part.
  • the movable part moves back via a spring tension system, or via a roller system. This movement can cause the control unit to deactivate and thus the walking system to re-start.
  • the movable part can also be adapted to be move back to its initial position by reducing the force to less than that of the predetermined threshold, e.g., to less than 1 N.
  • the moving walking system according to the invention thus advantageously facilitates a passenger on the walking system in a case of emergency. It advantageously also provides the user with a means of communicating with the control unit and indeed the moving walking system as a whole, thereby significantly improving user safety.
  • the movable part and the fixed part of the bridging system of the moving walkway represent a touchable surface wherein the ratio of the touchable surface provided by the movable part and by the fixed part is less than 1:4 respectively preferably less than 1:10.
  • the width of the movable part that means the distance between the beginning of the bridging system and the beginning of the fixed part, is advantageously less than 200 mm, more preferably less than 150 mm, more preferably between 40 mm and 120 mm.
  • the width of the fixed part is preferably at least four times larger than the width of the movable part, more preferably at least ten times larger.
  • the width of the movable part may be 60 mm and the width of the fixed part 600 mm.
  • the bridging system of the moving walkway can further comprise a second movable part, wherein the two movable parts, i.e. the first movable part and the second movable part, are arranged at opposite ends of the bridging system, i.e., wherein the fixed part is positioned between both of these movable parts, i.e. the first movable part and the second movable part. It is preferred that these two ends can be adapted to work in opposite directions. This provides anti-trap protection independent of the direction in which the moving walking system is going.
  • the handrails of the handrail system of the moving walkway are adapted to be moved with different speeds. This provides a handrail of a moving walkway which can be tailored to match the speed of the pallets of the walkway should this be required or desired.
