  • TIMS train information management system
  • the present invention is configured such that, to avoid the opening of a door 21 during travel of a train 120, an emergency brake is applied, upon the operation of the unlock switch 41 during the travel of the train 120, thereby causing the train 120 to suspend after a while. After that, the TIMS confirms velocity zero, and unlocks the door 21.
  • a lock mechanism 22 is shown in two ways, i.e., lock and unlock.
  • Fig. 2 shows a condition in which the passenger has pushed the door 21 outside the car 130.
  • the door 21 is moved to be more distant from the car body of the car 130 by an operation of the opening and closing mechanism 23.
  • the passenger pushes the door 21 in the lateral direction in which the door 21 moves, thereby allowing the door 21 to be fully opened.
  • Fig. 3 shows a condition in which the passenger is going to lift up and rotate an apron 33 on a ladder cover 32 (see Fig. 6) covering a ladder 31 (see Fig. 6) installed on the floor to extend out the apron 33 outside the car 130.
  • Fig. 4 shows a condition in which the passenger walks on the extended-out apron 33 outside the car 130 and sees the door 21 of the opposite car 130 in front. Since the door 21 of the opposite car 130 is slightly distant from the car body as described above, the passenger draws the door 21 and moves the door 21 in the lateral direction to fully open the door 21.
  • the passenger After fully opening the door 21, the passenger extends out the apron 33 in the opposite car 130 toward the passenger, to allow the aprons 33 to be positioned between the cars 130.
  • Figs. 5 and 6 shows the train 120 in which the cars 130 are coupled to each other.
  • the emergency exit apparatuses 1 are equipped at the end portions of the cars 130. Between the coupled cars 130, the passenger can move to the next car 130. More specifically, the doors 21 of the cars 130 are both fully opened and the aprons 33 are both extended out. The doors 21 move outward from the car bodies of the cars 130 and in the lateral direction to be opened. Under this condition, the passengers start to sequentially move to the opposite car 130.
  • Fig. 5 shows that the emergency exits 150 are positioned to conform to each other in the lateral direction. This is because, opposite passages 190 are desirably arranged to extend in straight line shape to facilitate the evacuation of the passengers.
  • the emergency exits of this type are biased relative to the center of car bodies.
  • the passengers can escape from the cars through such emergency exits but cannot walk straight to move between cars because the opposite passages 190 are not arranged to extend in straight line shape.
  • the cars 130 of this embodiment are more advantageous in terms of safety and time than the cars equipped with the biased emergency exits.
  • Figs. 7 through 10 show a condition in which the passenger exits from the car.

  • the operation procedure in this case is as follows.
  • Fig. 7 shows that the passenger has operated the unlock switch 41 at the emergency exit 150.
  • the TIMS detects and recognizes an unlock signal and causes either one or both of the public address equipment and the indication equipment to announce and display an operation method and an evacuation method for passengers.
  • the present invention is configured such that, the emergency brake is applied, upon the operation of the unlock switch 41 during travel of the train 120, thereby causing the train 120 to suspend after a while, for the reason described previously. After that, the TIMS confirms velocity zero, and unlocks the door 21. On the other hand, if the unlock switch 41 is operated in a stopped state of the train 120, the door 21 is immediately unlocked under the zero velocity. In Fig. 7, operation of the lock mechanism 22 is shown in two ways, i.e., lock and unlock.
  • Fig. 8 shows a condition in which the passenger has pushed the door 21 outside the car 130.
  • the door 21 is moved to be more distant from the car body the car 130 by the operation of the opening and closing mechanism 23. Since the door 21 moves distant from the car body and in the lateral direction, the passenger pushes the door 21 in the lateral direction in which the door 21 moves, thereby allowing the door 21 to be fully opened.
  • Fig. 9 shows a condition in which the passenger is going to kick a near side of the ladder cover 32 covering the ladder 31 installed on the floor outside the car with the door 21 fully opened.
  • Fig. 10 shows a condition in which the ladder 31 and the ladder cover 32 kicked out by the passenger from the car 130 are automatically set by a gravitational force.
  • the ladder cover 32 is separated from the ladder 31 and the ladder 31 which is retractable is extended and set between the emergency exit 150 and the track 110.
  • Figs. 11 and 12 show a condition in which the passenger can escape from the car 130 of the train 120 with the doors 21 fully open and the ladders 31 extended out. Under this condition, the passengers sequentially step down the ladders 31 outside the car 130.
  • the ladders 31 for use in escape are set between rails of straight track.
  • the passengers may escape from the car 130 on curved track. So, if the end portion of the car 130 is biased relative to the track 110 and an end portion of the ladder 31 contacts the rail or a fastening device thereof, this may negatively affect the evacuation of the passengers. Therefore, it is desirable to position the emergency exits 150 as close to the center of the car body as possible and arrange them to be laterally symmetric.

  • Figs. 35 and 36 show examples which can solve such a problem, in which one ends of cables 47C are connected to fix-side end portions of output shaft of solenoid reciprocation mechanism 34C3 or 34C, and opposite ends of the cable 47C are configured to be pulled together inside and outside the car 130.
  • the cables 47C which are the backup fix mechanism 47 and the associated auxiliary equipment are structured such that the opposite ends thereof are located inside and outside the car 130 and the one ends thereof are connected to the output shafts of the solenoid 34C3 or 34C4. By pulling any of the opposite ends of the cable 44C, the output shafts of all the solenoids are fixed at the fix position by fixing members (not shown).
  • the fix detection mechanism 48 is configured such that a limit switch (not shown) attached to an appropriate position of the fix mechanism, for example, a position at the tip end of the air cylinder 34C1 which is opposite to the wedge 34B detects the presence/absence of the wedge 34B which may contact the limit switch.
  • a limit switch (not shown) attached to an appropriate position of the fix mechanism, for example, a position at the tip end of the air cylinder 34C1 which is opposite to the wedge 34B detects the presence/absence of the wedge 34B which may contact the limit switch.
  • the ladder 31 is fixed when the wedge 34B presses the press member 34A and the fix pin 34A1 is inserted into the ladder 31. So, it is appropriate to detect the fixed state and the unfixed state in such a manner that the ladder 31 is fixed when the wedge 34B pushes back the contact of the limit switch and the ladder 31 is unfixed when the contact of the limit switch is at a free position.
  • the emergency exit apparatus 1 of the present invention is considered as follows.
  • the TIMS 49 Upon the unlock switch 41 being operated, the TIMS 49 immediately causes the train 120 to apply the emergency brake. Wen the unlock switch 41 is operated during travel of the train 120, the TIMS 49 waits to transmit the unlock signal ULS, to keep the door 21 locked.
  • This function is achieved by a function of the TIMS 49 to check velocity information VEI.
  • the TIMS 49 sends the unlock signal ULS to the unlock control mechanism 43.
  • the lock force is kept by the lock spring mounted in the drive mechanism 22C or by the weight of the piston and the piston rod.
  • the door 21 is locked when the contact of the contactor of the electricity control circuit falls.
  • the TIMS49 is configured to detect the location where the door 21 should be opened is both end portions of the train 120, or an intermediate portion of the train 120. When detecting that the location is the intermediate portion, the TIMS 49 sends the fix signal FXS to the fix mechanism 34 before the door 21 is opened, to allow the passengers to move between the cars without any troubles.
  • the return spring of the press member 34A usually keeps the ladder 31 unfixed.
  • the door open keeping mechanism 23F is added to keep the door 21 fully opened.
  • the TIMS 49 plays an important role. If the TIMS 49 is not functioning, "the door system 2 is opened from inside or outside the car 130" is required at minimum. To this end, the following function is added to the emergency exit apparatus 1:
  • the backup fix mechanism 47 is equipped to allow the fix mechanism 34 of the ladder 31 to operate. These are located in the vicinity of the floor of the passage inside the car 130 or under the floor outside the car 130. By operating any of them, “fix state” is accomplished, and by returning it to its original state, “unfix state” is accomplished.
