A double deck bus has a wide front entrance door and two rear exit doors, one from each deck. The upper deck is at selected standing headroom height from the lower deck, and at selected sitting headroom height from the vehicle roof. A channel passageway with selected standing headroom is provided lengthwise of the upper deck. A curved front stairway leads from the front entrance door to the front end of the upper deck passageway, and a descending stairway leads from the rear end of said passageway to one of the rear exit doors. The fare box is located within the curve of the front stairway to be visible to the driver, whose seat is well above the lower deck. An engine compartment is provided at the rear end of the bus, and a wall separates it from the lower deck passenger compartment. A passageway also is provided along the lower deck from the area of the fare box to the other rear exit door, and is offset laterally from the upper deck passageway so as to provide selected, standing headroom throughout its length. |

DETAILED DESCRIPTION The present invention provides a double deck bus having the upper deck spaced from the lower deck to provide selected, standing headroom on the lower deck, and from the roof to provide selected sitting headroom only on the upper deck.
An upwardly open channel passageway extends lengthwise of the upper deck, the front end of such passageway opening onto the upper end of a curved front stairway ascending from the lower deck, and the rear end thereof opening onto the upper end of a rear stairway descending to an exit door at the rear end of the bus.
A wide front entrance door is provided adjacent the lower end of the front, curved stairway, and the fare box is located in the curve of this stairway for monitoring by the driver of the bus, whose seat is elevated above the lower deck.
A passageway also is provided along the lower deck of the bus, and is offset laterally from the channel passageway of the upper deck.
This lower deck passageway terminates at its rear end adjacent a second rear exit door.
A propulsion engine and mechanical accessories, including air conditioning equipment, are mounted in an engine compartment provided rearwardly of the lower deck passenger compartment, and is sealed from the passenger compartment by a wall.
Thus, the passengers for both decks enter at a single, wide, front entrance door, and, in passing the fare box, drop their fares therein under the monitoring eye of the elevated driver, and move rearwardly along the passageways of both decks with standing headroom.
All of the seats of both decks are easily accessible from their respective passageways, and provide full sitting headroom for all passengers seated therein.
In exiting, the passengers, after leaving their seats, continue their rearward movement along their respective passageways to the separate exits provided, one for each of the decks.
The termination of the lower deck passenger compartment ahead of the engine compartment tends to equalize the total loaded weight of the bus on both front and rear wheels, and thus allows the use of only four so-called super single tires without exceeding the usual legislated maximum loading of 18,000 lbs
