ABSTRACT:
A guide for supporting a moving handrail or an escalator or moving walk is formed from a sheet of rolled spring steel or the like. The guide fits onto the top edge of a glass balustrade on the escalator or walk. The guide is secured to the glass balustrade solely by means of a spring clamping action which results from stressing the guide when it is forced down over the glass. The guide is formed with opposed planar clamping surfaces which flank the glass balustrade and are biased inwardly thereagainst by outer radiused edges of the guide which are stressed when the guide is pressed onto the glass. The radiused edges, when stressed, act as hairpin or torsion springs to force the clamp surfaces toward the glass. A gasket of paper or plastic is mounted directly on the glass for engagement by the clamping surfaces to provide increased protection for the glass.
