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 from 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,the beam including, a first 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 first rod connected to the beam mounting portion of the combined pivot/bracket,the first rod comprising a hollow flexible elongated frusto-conical tube,a second elongated rod having a length extending between a butt end and a tip end of the second rod, the butt end of the second rod attached to the beam-mounting portion of the combined pivot/bracket, the second rod disposed generally parallel to and spaced below the first rod, anda cross piece having a first end connected adjacent the tip end of the first rod and a second end connected adjacent the tip end of the second rod.
