Abstract
The handrail reentry guard housing on a moving walkway or an escalator is provided with a retrofittable shield which is attached to the underside of the guard housing, and which fills the space between the moving handrail and the guard housing. The shield is formed from complimentary halves which are made from formed plastic sheets. The shield halves are somewhat flexible so as not to form a rigid counterpart to the moving handrail. Hook and loop components are secured to the guard housing and to the shield halves to allow for retrofit securement of the shield to the guard housing.
