Definitions

  • the invention is particularly useful as an emergency release mechanism for actuator driven doors which are positively latched in the closed position. Doors of this type may be found on vehicles, particularly railway vehicles, and most recently as safety doors along the edge of a platform in an underground railway or mass rapid transit railway system.
  • a latch arrangement for at least one door having an opening and closing mechanism comprising co-operating latch members arranged to mutually engage to latch a door in the closed position and, for unlatching the door manually, a handle in the door connected to a first unlatching member carried in the door which is arranged upon movement of the handle to unlatch the co-operating members, and in a door-frame a member disposed to abut the member in the door, in the closed postion, for movement therewith to effect de-energisation of a prime mover in the opening and closing mechanism.
  • the door-frame member is arranged to release pneumatic pressure from an actuator cylinder to permit movement of the door.
  • the headframe member may be arranged to effect electrical isolation of the actuator.
  • platform edge doors which according to latest safety thinking, are installed along a platform edge in an underground railway or mass transit station to provide an effective safety screen between waiting passengers on the platform and the railway track area and particularly a moving vehicle.
  • a continuous half-glazed screen along the platform edge with sliding doors spaced apart at intervals co-incident with the door spacing of the railway vehicles.
  • the screen doors are operated by actuators and normally latched in the closed position except when a train has come to rest in the correct position whereupon the screen doors are opened, together with the vehicle doors, to permit passengers to enter and exit the vehicle.
  • the screen doors maybe automatically or, at least, remotely operated and are not intentionally provided with any means of opening accessible to waiting passengers. ,
  • each door, or each set of doors is provided with a handle on the track side which may be operated by a passenger standing in the open doorway of a vehicle, and which unlatches the doors. Preferrably this also releases pneumatic pressure from the door actuator which maybe retained normally to positively hold the screen doors in the closed position. Thus in an emergency the screen doors can be opened manually.
  • Fig 1 there is shown a side view of part of a screen door carriage and latching mechanism for a pair of bi-parting doors.
  • the two doors are of the sliding type and are carried by roller carriages, two of which are shown at 3 and 4 respectively which run in roller tracks 5 and 6 extending longitudinally with respect to the screen (not shown) and positioned above the door opening and to either side thereof.
  • the inner edges of the doors are provided with lip seals la and 2a which abut each other when the doors are closed, as shown in the drawings.
  • the doors 1 and 2 are suspended from carriages 3 and 4 by brackets 7 and 8 which extend downwardly through elongate slots in the underside of a headframe cover.
  • the tracks 5 and 6 carriage, brackets and other parts of the mechanism are all concealed by the headframe cover, not shown in the drawing.
  • the actuator which powers the door closing/opening mechanism is generally indicated at 9 and comprises a long stroke, double-acting linear actuator in which a moving piston (not shown) located within the cylinder 10 of the actuator is connected to an actuator rod 11.
  • the motive power of the actuator 9 is provided by pneumatic pressure which maybe admitted through valve means to either end of the actuator cylinder 10.
  • the actuator rod 11 is connected to the drive bracket 13 of the left hand door 1 and the actuator force is transmitted to the right hand door 2 by an endless belt 30 connected to both brackets. In the drawing the door on the left is driven and that on the right is a slave door.
  • the mechanism for latching the doors in the closed position comprises a pivoted latch member 12 mounted on the bracket 13 of the driver door and which a hooked part 12a engages with a peg or block 14a fixed to the bracket 14 of the slave door.
  • the latch member 12 may be pivoted anti-clockwise to disengage the latch release the doors from the locked position.
  • the latch member 12 is operated by abutment with a flanged latch striker 15 carried towards the outer end of the actuator rod 11.
  • This remote end of rod 11 is provided with a resilient overtravel mechanism 16, by means of which the drive bracket 13 is connected to the actuator rod 11 for limited relative movement.
  • the rod 11 is permitted a limited amount of overtravel during which the latch striker 15.abuts a heal 17 on part of the latch member 12, and rotates the member 12 into locking engagement with latch block 14a on the brackets 14, providing that the slave door has not been obstructed and has also completely closed.
  • This position of the rod-11 and associated parts, reached through the overtravel movement is held while the doors are locked, by residual pressure in the actuator 9.
  • the emergency unlatching mechanism provided by the invention is intended inter alia to permit manual release of the trapped pressure in the actuator thereby unlatching the doors so that they may be pushed open.
  • the screen doors have an emergency release handle (not shown) for manual operation located on the track side of one of the doors.
  • the emergency release handle is connected to a push rod 18 mounted within the door 2 for vertical axial movement.
  • a further rod or member comprising two parts 19 (Fig. 2) and 19a (Fig. 3) which carry several fixed abutments or flanges, a first of these is a member 20 fixed to the rod 19 adjacent latch member 12 and in a position to abut a pin 20a secured in the latch member 12.
  • a second such member provides a shoulder 21 on the rod 19 adjacent an isolating valve 22 connected in the pneumatic system of actuator 9.
  • Isolating valve 22 comprises a pressure release valve having a valve operating member 23 which is depressed to open the valve 22 and release actuator pressure.
  • the emergency release arrangement of the described embodiment only isolates the pneumatic parts of the door actuator system and leaves the electrical control system uninterrupted.
  • the switch 24, in the embodiment, is a rocker type switch and the rocker operating member is disposed to be engaged by the shoulder 21 formed on rod 19 and preferably subsequent to said shoulder having deployed the valve operating member 23.
  • the member comprising shoulder 21 on rod 19 also provides two stepped shoulders 25 and 26, seen in Fig 2, which co-operate with a spring loaded plunger or detent mechanism to engage and hold the rod 19 in either of two deployed positions.
  • This mechanism comprises a plunger 27, sprung against the member 21a by a coil spring 28 in compression. The plunger may be withdrawn against the bias of spring 28 by means of a latch type arrangement operated by a square drive keyway 29, a co-operating key being normally issued to authorised personnel for the purpose of resetting the emergency door release mechanism.
  • the rod 19 may be raised further to obtain operation of the electrical isolation switch 24, in which position plunger 21 extends to a second step engaging with the second stepped shoulder 26. Again the electrical circuits can only be remade by resetting the mechanism by withdrawal of plunger 27. This second position cannot normally be achieved by operation of the passenger accessible door mounted emergency handle only, because the rod located in the door does not impart sufficient lift to the rod in the door-frame housing.
  • the additional lift required is provided in one embodiment by means of a straight forward lifting handle 34 attached to the member 21a, see Fig 2.
  • the door actuator may be isolated e.g. for maintenance by means of a lever 33 pivoted about a horizontal axis 31 and having at one end a handle 32 which may be pulled down on the platform side of the platform doors.
  • the other end of lever 33 is linked to the upper end of rod 19, so that by pulling down on the handle 32 the rod 19 is lifted and the actuator isolating valve 22 is operated.
