ABSTRACT:
The handrail reentry housing on an escalator or moving walkway is provided with a set of journaled rollers which are disposed adjacent to each of the exposed surfaces of the handrail. The rollers are spaced apart slightly from the handrail, and are formed from a low coefficient of friction material such as ultra high molecular weight polyethylene. The rollers are freely rotatable and do not contact the moving handrail, therefore objects that may enter the space between the handrail and the reentry housing can be quickly and easily withdrawn without becoming entrapped therein.
