Abstract
A framework structure for an inclined passenger conveyor has a pair of horizontal framework portions and an inclined framework, each being a truss with a rectangular cross-section, the horizontal framework portions being at opposite ends of the framework structure and at a different height from each other with the inclined framework being connected between them. The horizontal framework portions each having an external shape in the form of a substantially rectangular parallelepiped and have one end surface angled at an angle to the horizontal axis thereof which is part of the angle between the horizontal framework portion and the inclined framework. The inclined framework has an external shape in the form of a substantially rectangular parallelepiped and has both end surfaces angled at an angle to the longitudinal axis thereof at angles which are respectively the remainder of the angles between the inclined framework and the horizontal framework portions, the angled end surfaces of the respective horizontal framework portions and the inclined framework abutting each other, and joint devices connecting the inclined framework and the lower and upper horizontal framework portions into a rigid framework structure.
