Definitions

  • the invention refers to an anti-entrapment safety system, in particular to an anti-entrapment safety system for a passenger moving system 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 an anti-entrapment safety system for a passenger moving system comprising preferably a first endless handrail belt and preferably a second endless handrail belt, wherein the safety system comprises a plurality of movable parts wherein a first movable part is adapted to respond to an entrapment force (F e ) applied thereto and wherein the response comprises an upwards rotation or a downwards rotation of the first movable part.
  • the upwards rotation or the downwards rotation of the first movable part preferably activates the anti-entrapment safety system when the rotation exceeds a pre-determined threshold value.
  • the threshold value is preferably defined as a rotation in the range of 0.5 to 20.0 degrees.
  • Handrails and handrail systems for moving walking systems including variable speed moving walking systems are already known in the art.
  • JP H11 301857 discloses a device for a handrail of a variable speed moving walkway wherein the device is adapted to initiate an emergency stop of the moving walkway in the event of an entrapment about the handrail belt.
  • the device comprises brushes which are arranged without gaps from the surface portion of the handrail to alert passengers about the approaching changeover of handrails and a separate detecting means provided therebelow for detecting an entrapment.
  • the detecting means comprises a shielding plate, which is forced in the upwards direction via a spring positioned underneath so that any downward force will cause the shielding plate to rotate downwards and cause an emergency stop of the moving walkway.
  • any downward force be it intentional i.e., an entrapment, or unintentional i.e. no entrapment but accidental contact with the shielding plate, will cause the moving walkway to come to an emergency stop. This can be both inconvenient and dangerous for the passengers travelling on the moving walkway
  • JP2001106464 discloses a variable speed moving walkway having a foreign matter detection means positioned on the handrail at the point where a first handrail ends and a second handrail begins, wherein said detection means is comprised of a sliding mechanism which slides backwards upon an entrapment and activates a limit switch causing the moving walkway to stop.
  • said detection means is comprised of a sliding mechanism which slides backwards upon an entrapment and activates a limit switch causing the moving walkway to stop.
  • any force be it intentional i.e., an entrapment, or unintentional i.e., no entrapment but accidental contact with the sliding mechanism, will cause the moving walkway to come to an emergency stop. This can be both inconvenient and dangerous for the passengers travelling on the moving walkway
  • inventive anti-entrapment system and a passenger moving system comprising the inventive anti-entrapment system are the subject of the appended claims and are described in further detail in the following embodiments and figure description.
  • the invention relates to:
  • the invention also relates to:
  • the invention also relates to:
  • the further anti-entrapment safety system is adapted to differentiate between a force of impact (F i ) and a force of entrapment (F e ), wherein the further anti-entrapment safety system is adapted to respond to a force of entrapment only.
  • this advantageously ensures that inadvertent or accidental rotations of any entrapment trigger which may occur during normal operation, do not cause unnecessary shutdowns of the passenger moving system i.e., "false alarms". Furthermore, this advantageously provides a passenger moving system that comprises a plurality of inventive anti-entrapment safety systems around the handrail belt at the points where entrapment is most likely to occur, wherein the safety systems are independent of each other and capable of simultaneously stopping the passenger moving system whilst also facilitating the release of any trapped material or item at any point about the handrail belt which can be contacted by a passenger. Thus, should one safety system fail, the other system is still able to detect entrapments and respond accordingly.
  • the passenger moving system comprises a variable speed passenger moving system or a constant speed passenger moving system.
  • an anti-entrapment safety system 10 according to a first embodiment of the invention and an anti-entrapment safety system 20 according to a second embodiment of the invention are positioned about a first handrail belt 1 and a second handrail belt 2 wherein each system 10, 20 are shown to be at rest, i.e., the passenger moving system is in normal operation mode and no entrapments have occurred.
  • the safety system 10 is positioned between a first handrail belt 1 and a second handrail belt 2 whereas the safety system 20 is positioned about handrail belt 2 only.

  • the movement of the entrapment trigger 103, in particular the rotation of the entrapment trigger 103 from the position shown in fig. 1a to the position shown in fig. 1b is caused by the entrapment force F e .
  • the upwards rotation of the entrapment trigger 103 exposes a larger surface area of the handrail belt 2 and causes the passenger moving system to stop. It also may help to relieve the entrapment.
  • the upwards rotation of the entrapment trigger 103 also causes the deflector 102 to slide across the outer surface of the fixed part 101 (as shown by the straight dotted arrow). Fig.
  • FIG. 1b also shows the presence of a rolling element 1033 on the underside of the entrapment trigger 103.
  • two rolling elements 1033 are comprised within the entrapment trigger 103 wherein the rolling element 1033 is a wheel.
  • the safety system 20 may also be activated via the same entrapment that activates the safety system 10.
  • the mechanism by which the safety system 10 operates is explained further in figs. 2a to 3d .

  • the safety system 10 further comprises an actuator 104, wherein the actuator 104 comprises a spring 1041 in a spring housing 1042; a movable part 105 and a sensor 106. It is possible to use a pre-loaded sensor 106 in order to reduce the reaction time when an entrapment occurs In this particular example the sensor 106 is a limit switch.
  • the deflector 102 facilitates the holding of the movable part 105 in place and vice versa.
  • the actuator 104 is comprised within the movable part 105 wherein said actuator 104 is in communication with the entrapment trigger 103.
  • the actuator 104 and the entrapment trigger 103 are connected at a joint X, wherein the joint X is preferably a pin (shown in fig. 2b ).
  • the actuator 104 exerts a force, e.g., a biasing force, upon the entrapment trigger 103 via the spring 1041.
  • the movable part 105 shares an interface I with the limit switch 106, as shown by a dashed line. At the interface I, the movable part 105 and limit switch 106 are in contact.
  • the entrapment trigger 103 shown in this particular example comprises a groove G which complements a surface S of the actuator 104.
  • Fig 2b shows a magnified representation P of the groove G and surface S.
  • the entrapment trigger 103 rotates about point A when an entrapment occurs causing the groove G to move around the surface S of the actuator 104. This is shown more clearly in figs 3a to 3d .
  • Figs. 3a to 3c describe in detail how the safety system 10 according to the invention operates.
  • Fig. 3a shows the safety system 10 in its "rest" position during normal operation of the passenger moving system (not shown);
  • fig 3b shows the safety system 10 just before an entrapment force F e causes the entrapment trigger 103 to fully rotate upwards and move from a vertical forwards position V f to a vertical backwards position V b , and thereby activating the safety system;
  • fig. 3c shows the safety system 10 when activated and
  • fig. 3d shows an exploded view of a cam 1032 in relation to a movable part 105.
  • Fig. 3a shows the safety system 10 as shown in fig 2a , with the exception of the fixed part 101.
  • Fig 3a shows the points of rotation A, B of the entrapment trigger 103 and the actuator 104 respectively.
  • the spring 1041 causes the actuator 104 to exert a force F upon the entrapment trigger 103, i.e., exerts a biasing force on the entrapment trigger. This establishes the rotation threshold.
  • the entrapment trigger 103 leans towards the handrail belt (not shown) in a vertical forward direction V f providing a gap of a distance of 1.5 mm between the contactable surface of the entrapment trigger 103 and the handrail belt.
  • the entrapment trigger 103 leans towards the handrail belt at an angle that allows the wheels 1033 of the entrapment trigger 103, to contact the handrail belt (not shown) at all times.
  • the wheels 1033 rotate according to the moving direction and moving speed of the handrail belt.
  • the wheels 1033 are preferably positioned away from the edge of the entrapment trigger on the surface facing the handrail belt (this is shown more clearly in fig. 1b )
  • the deflector 102 is held in position via the movable part 105 and vice versa during normal operation of the passenger moving system.
  • the safety system 10 is adapted to distinguish between a force caused by entrapment F e and a force caused by impact F i .
  • a force of the latter type is shown by the downwards arrow F i , whilst a force of the former type is shown in fig. 3b by the curved arrow F e .
  • the safety system 10 will only respond to an entrapment force F e , since this force will rotate the entrapment trigger 103 in the upwards direction in an amount sufficient to exceed the rotation threshold, which then activates the limit switch 106.
  • Fig. 3b shows the safety system 10 upon application of an entrapment force F e .
  • the entrapment trigger 103 rotates upwards about point A in an anti-clockwise direction, which causes a simultaneous rotation of the actuator 104 about point B in a downwards anti-clockwise direction.
  • the downward rotational movement of the actuator 104 pulls the movable part 105 downwards via a rotation about point C in an anti-clockwise direction.
  • the entrapment force F e is lower than the rotation threshold established by the force F supplied by the actuator 104 on the entrapment trigger 103 via the spring 1041, the entrapment trigger 103 will not rotate any further upwards, the movable part 105 will not move further downwards thus the deflector 102 will not be released. This ensures that the passenger moving system is not unnecessarily stopped.
  • the safety system 10 will continue to react according to fig. 3c .
  • Fig. 3c shows how the actuator 104 rotates further about point B in an anti-clockwise direction such that rotation point B is moved to a position below that of rotation point A.

  • the shape of the cam 1032 is such that a rotation of 8.0 degrees causes it to contact and rotate the movable part 105 thereby stopping the passenger moving system.
  • Fig. 4a shows an inventive anti-entrapment safety system 20 according to a second embodiment of the invention when in its "rest position" i.e., the passenger moving system is in normal operation mode.
  • the safety system 20 according to this embodiment comprises an entrapment trigger 203, a deflector 202, a sensor 206 - in this particular example the sensor is a limit switch 206.
  • the deflector 202 and entrapment trigger 203 are connected such that they form a single movable part; however, only manipulation of the entrapment trigger 203 will cause a manipulation of the deflector 202.
  • the entrapment trigger 203 is adapted to be manipulated by an external force, in particular an entrapment force F e .

This renders the deflector 202 and consequently, the entrapment trigger 203 under a downward force F, i.e., they are biased.
  • the cam 204 comprises a groove G and is located at each lengthwise end of the entrapment trigger 203 such that at least a length of the lateral edges of the deflector 202 rests upon a vertical top surface of the cam 204 (shown more clearly in figs. 5a to 5d ).
  • the lateral edges of the deflector 202 refer to the edges of the shortest sides of the deflector 202, i.e., those which lie perpendicular to the direction of the handrail belt (not shown).
  • the cams 204 are preferably identical and are positioned such that they form mirror-images of each other. Each cam 204 is rotatable about a point D. This is explained in further detail in figs. 5a to 5e .

  • the limit switch 206 is shown to be positioned opposite the cam 204 located at the opposite end of the deflector 202 compared to the position shown in fig. 4a .
  • An entrapment force F e (not shown) causes the entrapment trigger 203 to rotate downwards from its resting horizontal position H 0 to an activated vertical position V a which serves to create a gap around the handrail belt (not shown). Rotation of the entrapment trigger 203 causes the deflector 202 to rotate also.
  • the simultaneous downward rotation of the deflector 202 and the entrapment trigger 203 occurs along rod 208 which allows for a rotation with respect to the balustrade (not shown) of the passenger moving system.
