Definitions

  • a power-operated door operating gear in which a door position sensor applies power to open the door or doors when the door is or doors are moved manually away from the fully closed position.
  • the sensor may provide a door closed signal to a remote operator, and may be nterlocked with vehicle operatin-g gear.
  • the preferred sensor comprises a reed switch and a magnet for changing the state of the switch when the door is fully closed.
  • a further development of this practice is to arrange that the doors close in the manner described above, but the doors are tted with a handle, which when operated, actuates a switch mounted above the doorway.
  • This switch in turn operates an electropneumatic valve which allows compressed air into the double acting cylinder assemblage in such a way as to cause the doors to open.
  • the door-closing force is maintained until the train has stopped or almost stopped, and is then removed entirely, i.e. the driver or other attendant releases air from the door-closing ends of the door-actuating cylinders, to permit rapid opening when desired by a passenger.
  • the manual opening of a door actuates sensing means which, in addition to initiating powered opening of that door, signals to the driver or other attendant that a door is open, and/ or prevents starting.
  • the sensing means is a reed switch arranged to be held in one state, preferably closed, by an associated magnet except when shielded by a ferrous or ferromagnetic member only when the door is fully closed.
  • the switch may be stationary and the magnet mounted on the door, or vice versa, so that the switch will change its state only when the door is fully closed; preferably the switch is open when the door is fully closed.
  • other sensors e.g. camoperated microswitches, could be used.
  • FIG. 1 is a fragmentary view in elevation illustrating the left sliding door and the door-operating means
  • FIG. 1A is a view similar to FIG. 1 illustrating the right door and door-operating means
  • FIGS. 2 and 3 show a door sensing arrangement
  • FIG. 2A is a cross-section on line A-A of FIG. 2;
  • FIG. 2B is a fragmentary view illustrating a further door sensing arrangement
  • FIG. 4 is a schematic diagram of one possible form of control circuit.
  • doors 1 hang from carriages 11 which run on a track 12, and the normal practice is to construct the edges of the doors in rubber, so as not to harm any passengers caught therebetween.
  • a shield 2 mounted on top of each door leaf is a shield 2 constructed in mild steel or other ferrous metal. These shields 2, when the door is closed, enter a reed switch assembly 3, shown in more detail in FIGS. 2 and 3.
  • a double acting air cylinder assemblage 4 through a rack an pinion, causes a pulley 5 to rotate.
  • the driver from his controls at 15 causes an electrical signal from a source 20 to pass along the length of the train, which operates an electropneumatic valve 16 at each doorway and causes air to pass from reservoir 17 into one side of the cylinder assemblage 4. This rotates the pulley and causes the doors to be brought together. When the two door leaves abut,
  • the shields 2 enter the reed switch assembly and cause the reed switch to change its state, thus causing an electrical signal which indicates to the driver, e.g. by colored lamps 19, that the doors are closed.
  • a second reed switch assembly may be arranged at the extermity of the door opening.
  • a shield on the outer edge of a doorleaf can be arranged to enter the switch and operate same in the door open position.
  • the resulting electrical signal can then be used to indicate to the driver that the door or doors are open; the same signal can be arranged to operate an electropneumatic valve to exhaust the opening air pressure in the cylinder assemblage and thus allow the doors to be manually closed by a passenger.
  • this same switch having had its state changed by the initial manual closing movement, i.e. the first increment of movement, withdraws the shield from the reed switch causing a signal which can be arranged to operate the closing electropneumatic valve thus admitting air to the closing side of the cylinder piston and thereby completing the door closing under power.
  • FIG. 2 illustrates the reed switch assembly 3.
  • FIG. 2A shows that this switch assembly consists of a permanent magnet and a reed switch 9 with a space 14 therebetween. It will be seen if nothing is interposed between the reed switch and the magnet then the full force of the magnetic flux will act upon the reed switch causing its contact to be closed.
  • These components are contained in the ange parts of a channel-switch body 13 of a nonmagnetic material, e.g. plastics, so that their supporting means does not infiuence the magnetic field.
  • FIG. 2B is illustrated a modified sensing means which includes a stationary reed switch 9 and a magnet 10 mounted on the door.
  • a speedometer can be used to give permission to each door operating device that the doors can be safely opened, when the speed of the train is so low as not to be hazardous to passengers entering or leaving.
  • an automatic interlock can be provided, eg. instead of or in addition to the lamp 19, so that the train cannot be started until a signal indicating that all the doors are closed has been received.
  • the signal received from the reed switches following the opening or closing manual initiation by the passenger can be transformed, from its inherent comparative low power, by the utilization of relays to amplify the switching capacity for the .various duties required.
  • the signals can be fed into transistorized units known as solid state or logic modules whereby a programmed response can be obtained from a specific sequence of input signals from the switches. For instance, following the door open sequence it could be arranged to close the doors after a set period of time, or give an audible or visual signal that the doors are about to close.
  • the invention is not confined to doors of railway vehicles, or to biparting doors, but can be used with single doors, on road vehicles, or even on stationary installations.
  • a power-operated sliding door gear for doors adapted to be moved between closed and opened positions including power-operated door-actuating means operably related to the door, sensing means responsive to the door position for energizing the door-actuating means to move the door to the opened position in response to a manual door opening movement, the sensing means comprising at least one reed switch and an associated magnet for changing the state of the switch upon complete door closure.
  • the power-operated sliding door according to claim 1 including signalling means controlled by the sensing means for indicating the door closure to a remote operator.
  • the sensing means comprises a stationary reed switch and a magnet mounted on a door.
  • the sensing means comprises a reed switch and magnet in fixed relative positions, and a shielding member for shielding the switch from the magnet.
  • the power-operated door-actuating means is a double-acting fiuid-pressure cylinder, and including valve means under the control of a remote operator for admitting fluid to the cylinder for moving the door to the opened position and for exhausting said fiuid, and
