  • the doors are laterally offset relative to one another when the doors are closed whereby to provide a distance B between respective closing edges 19, 21 to enable a person to easily withdraw a limb, for example an arm, caught between the closing edges 19, 21 when the ombibus is set into forward motion, the direction of forward motion being indicated by arrow A.
  • each door 12, 13 is conventional and each door 12, 13 is mounted on the omnibus in the same manner, the operating mechanism and mounting being described below with respect to the leading door 12 of FIG. 1 for reasons of clarity.
  • the trailing door 12 is pivotably attached to a rotatable rod 14 by way of pivot arms 16, 18 each of which has one end secured to the rod 14 and its other end pivotally attached to an upper edge 20 and a lower edge 22 respectively of the door 12.
  • the pivot arms 16 and 18 maintain the door 12 in a substantially vertical attitude during pivoting of the door between its closed position and an open position.
  • the operating mechanism of the door 12 comprises a pneumatically operated double acting piston cylinder assembly or door engine 15 secured adjacent the upper.
  • a pneumatically adjustable member 17 of the piston cylinder assembly 15 is coupled to the rod 14 by way of a linkage 19 so as to rotatably drive the rod 14 when the piston cylinder assembly 15 is actuated.
  • the door is guided during pivoting by means of an upper guide track or runner 24 engaging between two rollers 26 which are mounted on a plate 28.
  • the plate 28 is mounted on a bracket 30 secured to the upper edge 20 of the door and is pivotable about a substantially vertical axis relative to the bracket 30 to allow free engagement of the rollers 26 with the track 24 during pivoting of the door 12.
  • the track 24 of the trailing door 13 has its end portion adjacent the leading door horizontally offset towards the interior of the omnibus.
  • a respective sealing member 32, 34 is attached to each closing edge 19, 21 by way of a respective elongate mounting bracket 36, 38, each sealing member 32, 34 extending along substantially the whole length of the respective closing edge 19, 21 and being made of a resiliently deformable material such as rubber.
  • the interior of each sealing member is preferably hollow to improve the flexibility of the sealing member.
  • the sealing members 32, 34 are laterally inclined to the respective doors l3, 12 such that when the doors 13, 12 are in their illustrated closed positions the sealing members 32, 34 extend towards one another to bridge the separation B existing between the respective closing edges 19, 21 of the doors.
  • This assembly has the advantage that if the doors close on, for example, the arm of a person who is about to board the vehicle and the driver puts the vehicle into forward motion, the force which normally would tend to drag the person forward and pinch his or her arm between the closing edges of the doors thus preventing his freeing the arm, will, instead, act to aid his freeing the arm.
