UNDERELOOR-ENG1NED singledeck buses now -being -titillt in this country commonly have their entrances ahead of the front axle. A wide, low step is provided, but jackLknife doors, where fitted, tend to take up space at the sides and require a cut-out in the lower step to allow the doOr panels
to turn. , To overcome these disadvantages, Park Royal Vehicles, Ltd., Loridon. N.W.10., has incorporated in, the lower part of the door a Small, vertically hinged panel. as ,high as the step.
the door is pushed open,the main panels turn to lie against the entrance partition, Whilst. the lap, lie. a'gainst-the step riser at right angles to the main panels.Thus the Cut-out usually provided in thersrep tsiti this case, taken out of the door itself.
Only a single panel is used in each half of INS door design, thus reducing the space occupied by the door in the open position. ManuaL or automatic operation can be arranged. The design is covered by patent applications.
