Abstract:
A crossing arm assembly that pivotally attaches to a support at the front end of a bus to block pedestrian traffic from crossing immediately in front of the bus when the bus is stopped, the crossing arm assembly comprising:a combined pivot/bracket pivotally attachable to the support, the combined pivot/bracket including a beam mounting portion; an elongated cantilevered beam having a length extending between a beam inner end and a beam outer end, the beam supported at the beam inner end on the beam mounting portion of the combined pivot/bracket; the beam being generally mass tapered along the beam length from the beam inner end to the beam outer end to concentrate beam mass closer to the support to reduce the tendency of the beam to sag under its own weight and/or to swing forward as the bus decelerates, and the beam including a flexible elongated rod having a rod length extending between a rod butt end adjacent the beam inner end and a rod tip end adjacent the beam outer end, the butt end of the rod connected to the beam mounting portion of the combined pivot/bracket without any additional structure being provided to prevent sagging.
