Secondly, the action of the door apparatus of present embodiment and the manual unlocking operation when urgent etc. are described.
Under normal conditions, when door- plate 12,13 is closed, be located at solenoid on the driver part 25 by demagnetization.Therefore, Lock Part 24 becomes the latched position of falling, by the sticking department 24b of snap lock parts 24 and the holding section 27,28 of door-plate upper end, with 12,13 lockings of two door-plates.And, at the vehicle in-track platform, to open correspondingly with its side door, controller 22 makes the solenoid excitation of driver part 25 to door switch unit 21d output control signal.Thus, Lock Part 24 is raised and keeps out of the way unlocked position (non-locked position), thereby this Lock Part 24 is disengaged with the engaging of holding section 27,28 of door-plate 12,13.On the other hand, drive sprocket 21a rotates and makes synchronous belt 21c walking, and door- plate 12,13 is opened.At this moment, solenoid is kept the state of excitation.
And when the side door with vehicle was closed that the control signal of self-controller 22 transfers to door switch unit 21d accordingly, the current reverse rotation of drive sprocket 21a made synchronous belt 21c walking and door- plate 12,13 cuts out.At this moment, receive the control signal of self-controller 22, solenoid is by demagnetization.Thus, Lock Part 24 is fallen, and returns latched position, and the sticking department 24b of Lock Part 24 engages with the holding section 27,28 of door- plate 12,13, and two door- plates 12,13 are locked in the lump.
Such manual unlocking operation when urgent describes when secondly, big deviation being appearred in the stop position of vehicle etc.Usually, when door- plate 12,13 is closed, because two door- plates 12,13 are locked, so door- plate 12,13 can't be opened.Therefore, for the passenger who makes rail side when urgent waits and can break away to platform side, so with the manually locking of releasing door-plate 12,13.The release of this door- plate 12,13 can be operated from the platform side operation with from rail side.
At first, the unlocking operation that carries out from platform side is described the key of the regulation that use had such as terminal attendant in this operation.When terminal attendant's grade of platform side was inserted this key the keyhole 50 of the side position in front of the door that is positioned at door-plate 13 and carried out rotating operation, meanwhile, key axial region 45 rotated.Before this rotating operation, shown in Fig. 6 (a) and Fig. 6 (b), the bond sites of second web 62 is in the bottom of second rotor plate 61.Therefore, second bar 46 and push rod 48 are placed in upper/lower positions.Shown in Fig. 7 (a) and Fig. 7 (b), when the rotating operation by key axial region 45 made second rotor plate 61 with key axial region 45 unitary rotation, second linking part 62 was followed this rising.Thus, second bar 46 rises and pushing push rod 48, makes the upper end (parts 48c) of push rod 48 outstanding to the top of door-plate 13.Thus, the sticking department 24b of Lock Part 24 is boosted, with the engage releasing of sticking department 24b with holding section 27,28.Like this, owing to insert the locking that keys in the keyhole 59 of door-plate 13 are removed door-plate 13 by rotating operation, therefore the opening operation that this directly carries out door-plate 13 in key operated can carried out.Then, after door-plate 12,13 is opened, when with hand from key leave or with key when keyhole 59 is extracted, second bar 46 is owing to the elastic force of second spring members 69 and the 3rd spring members 76 is fallen, key axial region 45 recovers original state naturally.
