  • Patent number: 5181595
    Abstract: An escalator or moving walkway handrail is guided along its path of travel over the curved newels of the escalator or walkway balustrades by a series of guide rollers mounted on a channel member which is fitted onto the balustrade newels. The channel member is generally U-shaped in cross section, and includes a bottom wall from which depend opposed side walls. The side walls are provided with a plurality of spaced slits which impart flexibility to the channel member. Sheet metal formed roller-mounting yokes are spot welded to the outside of the bottom wall, and the handrail guide rollers are mounted in the yokes. The channel member has straps on each end for fastening to handrail guides which lead to and from the balustrade newels. The guide assembly can be preassembled and bent around the newels on site when the escalator or walkway is installed.

  • Patent number: 4896759
    Abstract: A deflector is mounted on an escalator balustrade immediately below the moving handrail at the newel, or turnaround ends of the escalator. The deflector smooths the line between the handrail and balustrade and protects against clothing, packages, or the like, contacting the handrail in the exit newel end of the escalator. The deflector may be internally illuminated to heighten its awareness and design impact.
