DESCRIPTION:
BRIEF SUMMARY
FIELD OF THE INVENTION
The present invention relates to a guide rail for passenger and material transportation systems and a method for assembling same.
BACKGROUND TO THE INVENTION
Guide rails of the aforementioned type, are disclosed, for example, in DE-OS 40 14 069, consist of flexible plastic pipes which, after having been bent along a turn, are stabilized by being filled with a casting compound.
The disadvantage of this is that the guide rail cannot be used again in the old form after having been used once.
SUMMARY OF THE INVENTION
It is an object of the invention to design the guide rails in such a way that they can be used again.
In accordance with an embodiment of the invention, a multi-dimensionally bendable guide rail for passenger and material transportation systems is comprised of sheet-metal plates stacked on a guy rope, the sheet-metal plates having a central bore for the guy rope, a slightly conically outward extending cylindrical part being centered on the central bore, a radially outwardly curved transition piece in the form of an arch adjoining the cylindrical part, the sheet-metal plates being stacked on the guy rope so that the cylindrical part of one sheet-metal plate partially protrudes into the cylindrical part of an adjacent plate, the guide rail being bendable in its flexible state when the sheet-metal plates are slightly pressed together and being fixed in its curved form when the sheet-metal plates are strongly pressed together.

DETAILED DESCRIPTION OF THE INVENTION
A sheet-metal plate 3 is constructed, for example, as a square stamped plate part. In its centre, it has a slightly conical annular cylinder part 4 with a cable bore 6 in the middle. The cable bore 6 has a protrusion 15 to protect the guy rope 2. The plate 3 is made flat in the shape of an annular disk between the protrusion 15 and the cylinder part 4. The transition between the flat part and the cylinder part 4 is rounded.
The conical cylinder part 4 is designed in such a way that it is stayed on all sides at the point of contact 7 with its adjacent sheet-metal plate 8. The sheet-metal plates 3 are constructed in such a way that, set on top of one another in a stack, they permit both curves and torsions of the guide rails. The cylinder part 4 of one plate 3 partially protrudes into the cylinder part 4 of the adjacent plate 8. A curve-shaped transition piece 1 adjoins the conical cylinder part 4. As can be seen in FIG. 2, the point of contact 7 is formed on the right by the line of contact between the cylinder parts 4 of the sheet-metal plates 3, 8, while on the left it is formed by the line of contact between the start of the transition piece 1 of plate 3 and the inside start of the cylinder part 4 of plate 8.
The periphery of the sheet-metal plate 3 is formed into corrugated teeth on the outside adjacent to the transition piece 1, whereby the corrugated teeth 5 also overlap in the curved state in longitudinal direction of the guide rail, as shown at 9. The corrugated teeth 5 are radially aligned.
The periphery of the sheet-metal plate 3 has an opening for conveying means 10 for inserting conveying means such as chains and tangentially extending grooves 11 for fastening the guide rails.
Pressure plates 12, plate spring stacks 13 and a clamping device 14 which brace a guy rope 2 and maintain the stack at a constant initial stress are located at the start and end of the guide rails.
If a curved guide track is to be constructed, then the preassembled, slightly prestressed guide track is laid as desired and attached by means of mounting supp
