ABSTRACT:
The guiding apparatus comprises substantially rectangular rail holders and L-shaped rail holders. Main and follower travel rails or tracks are supported by such rail holders and there are provided side plates at which there are mounted the rail holders, the side plates being supported upon a carrier frame. These rail holders are provided at their attachment or fastening side with at least two respective centering protuberances or nubs or the like which engage into corresponding centering openings provided in the side plates to which the rail holders are fastened. The rail holders possess, at their rail contact side, a dovetail clamping device which, in cooperation with a dovetail profile or section extending along the underside of the travel rail or track, to reliably and easily releasably holds the travel rails and the rail holders by virtue of a clamping action which is exerted at all sides of the dovetail profile. The side plates, and, in particular, the position of their centering openings are produced true or exact to size and with narrow tolerances so that in cooperation with the related centering protuberances and the rigid dovetail clamping there is automatically ensured parallelism and alignment of the travel rails or tracks required for a quiet escalator or stair running. The guiding apparatus can be assembled without the need to resort to assembly fixtures or jigs and without subsequent adjustment from individual mass-produced parts.
