Abstract: An air conditioner of a track system vehicle includes two air conditioning units disposed in parallel in a horizontal direction and mounted on the roof of a vehicle, a plurality of outlets of two air conditioning units facing a vehicle center side, a first duct connecting two air conditioning units, and a second duct which bypasses to the vehicle ends.

Abstract: Described is an emergency door of a vehicle. An interior of the door and side part of front face of leading car are connected pivotally by an upper arm, lower arm, and first link bar so that a parallel linkage is composed, thereby enabling horizontal movement of the door. A stopper mechanism is composed such that an end of a second link bar is connecting pivotally to the first link bar, the bracket having an oblong hole is attached to a frame of a carbody, a pin fixed to the other end of the second link bar is received in the oblong hole, and the door can be stopped at its full open position when the pin contacts an end of the oblong hole.

Abstract: An emergency staircase includes a plurality of step forming members that are housed in a casing. A podium and a railing are fitted to the casing so that the podium and the railing can be unfolded against the casing. Each of the step forming members includes a pair of guiding parts which are arranged in parallel, and a step plate that is sandwiched between the guiding parts of each pair and fastened to each of the guiding parts, so that left and right pairs of resulting squarish U-shapes face each other. Inner guiding parts and outer guiding parts are mutually of a similar configuration, so that each inner one is relatively smaller than each outer one by the thickness of the part. The protrusions act as sliding contacts between adjacent guiding parts.

Abstract: An emergency door of a vehicle composed such that a large space is not required outside the vehicle to open the door, ingress of rainwater is prevented even in a case the emergency door is mounted at curved profile of front face of leading car, the door can be opened easily with small force, and the door is supported rigidly and steadily with compact configuration. The interior of the door 14 and side part of front face of leading car 10b are connected pivotally by an upper arm 36, lower arm 31, and first link bar 40 so that a parallel linkage is composed, thereby enabling horizontal movement of the door. A stopper mechanism 43 is composed such that an end of a second link bar 48 is connecting pivotally to the first link bar 40, the bracket 46 having an oblong hole 44 is attached to a frame 26 of the carbody, a pin 50 fixed to the other end of the second link bar 48 is received in the oblong hole 44, and the door can be stopped at its full open position when the pin 50 contacts an end of the oblong hole 44.

Abstract: The present invention aims at providing an emergency staircase, whereby an operator can promptly and easily arrange the preparation of detrainment with the staircase in an emergency, and the passengers can detrain with a feeling of security. An emergency staircase 40 includes a plurality of step forming members 44a to 44f that are housed in a casing 42, a podium 50 and a railing 46 that are fitted to the casing 42 so that the podium and the railing can be unfolded against the casing.

Abstract: An air conditioner is realized which allows an interior space of a track system vehicle to be felt to be wide by maintaining a ceiling of the vehicle high, allows the protrusion amount from a roof to be kept low, and is able to uniformly air-condition the atmosphere in the interior of the vehicle. Two air conditioning units 20, in which constituent devices are disposed in parallel in a horizontal direction, are mounted on the roof 10c adjacent to vehicle end sides of the track system vehicle 10, a plurality of outlets 44 of two air conditioning units 20 face a vehicle center side, the outlets 44 on an inner side in a vehicle width direction are connected to the first ducts 50 disposed on the ceiling face, and the outlets 44 on end sides are connected to the second ducts 52 which bypass to the vehicle ends, thereby being disposed up to the vehicle ends.
