Abstract
The reentry port where an escalator handrail passes out of view at the exit newel of the escalator is provided with an elastomeric reentry guard in the form of a collar surrounding the handrail. The collar has an elastomeric bumper part which is accessible from the exterior of the assembly, and which is mounted on a holder assembly which is contained inside of the escalator skirt housing. The holder and bumper are mounted for limited lateral movement concurrently with the handrail, and such movement is controlled by rollers mounted on the holder assembly, which rollers contact the sides of the handrail. The result is that lateral movements of the handrail as it moves past the reentry guard cause like lateral movements of the housing assembly and bumper. The handrail thus will not rub on the bumper, thereby providing a safer and longer lasting reentry guard.
