Escalator solid side truss construction

Abstract

A side truss assembly for escalators and moving walkways is formed of a corrugated main panel bounded by upper and lower stiffeners. The corrugation fold lines preferably extend perpendicular to the rise angle of the assembly and to the length of the stiffeners. End panels may be joined to the main panel to form a parallelogram construction with vertical end walls.

1 . An escalator side truss assembly, comprising a corrugated panel and top and bottom stiffeners extending substantially the length of the corrugated panel fastened to the corrugated panel.  
   
   
       2 . The side truss assembly of  claim 1 , wherein the corrugated panel has corrugation fold lines extending perpendicular to a length of the stiffeners.  
   
   
       3 . The side truss assembly of  claim 1  or  2 , wherein the corrugated panel is of stainless steel.  
   
   
       4 . The side truss assembly of  claim 3  further including at least one intermediate bracket affixed to the corrugated panel for supporting a roller assembly of the escalator.  
   
   
       5 . The side truss assembly of  claim 3 , wherein the stiffeners are fastened to the corrugated panel by welds.  
   
   
       6 . The side truss assembly of  claim 3  wherein the truss assembly is of a parallelogram shape, with a rectangular corrugated panel and an end panel located adjacent an end of the corrugated panel and between the stiffeners.  
   
   
       7 . The side truss assembly of  claim 6 , wherein the end panel is fastened to the stiffeners and corrugated panel by welds.  
   
   
       8 . The side truss assembly of  claim 6 , wherein the end panel is of triangular or trapezoidal shape.
