Definitions

  • the invention relates to an escalator step Receiving openings for storage on a step chain attached connecting axis.
  • the invention is based on the object Specify escalator step of the type mentioned at the beginning, the improved running properties with high load capacity owns and easily and inexpensively in large quantities can be produced.
  • the essence of the invention lies in a constructive Redesign of the escalator / moving walk step in such a way that sufficient load-bearing capacity of the step by production-oriented design can be represented without that the total weight of the step is increased.
  • one or more discrete support bearings provided, which is in the area between the bearings for the connecting axis in the step side walls on the Support the connection axis.
  • connection axis in conjunction with the Connection axis recordings and the inventive Support bearings used to reduce the deflection can be.
  • inventive local additional support without deflection other measures, such as ribbing, additional profiles, or similar.
  • additional support bearings which in correspond to their function as connecting axis receptacles, is the step above these points on the connecting axis fixed.
  • connection axis as Stabilizing element, the or the positive additional support bearing, the riser and the step part and the side parts work together to be rigid Step box or frame construction.
  • This larger Bending resistance moment of the escalator step makes it possible in addition, to be able to largely dispense with ribbing and to show thinner wall thicknesses.
  • escalator steps according to the invention is also possible simple die casting molds and tools possible and it can Material can be saved. Especially in larger ones Number of manufactured escalator steps / moving walk pallets this has an advantageous effect on the total costs.
  • an escalator step referred to, which consists of a tread part 2, a Riser part 3 and two side walls 5.1.5.2.
  • the Step part 2 and riser part 3 have, as usual grooves 2.1.3.1 running in the direction of travel.
  • the side walls 5.1.5.2 also have Receiving openings 7 for the storage of the escalator step on a connecting axis 8. Storage can over Bearing bushings 9 take place, which by means of clamping elements 10 the connecting axis 8 are secured against displacement.
  • the Connection axis 8 is via axis lugs 8.1 on step chains 11 stored on both sides of the escalator steps 1 run. On the step chains 11 are also over Ball bearings 13 mounted chain rollers 12 are arranged.
  • the escalator step 1 Under the step part 2 between the side walls 5.1 and 5.2, support bearings 14 provided, via which the escalator step 1 form-fitting is connected to the connecting axis 8. Under pressure the escalator step 1 is supported via the support bearing 14 on the connecting axis 8, the Bending stress in the rear area of the Step part 2 is greatly reduced.
  • This Measure is said to be the stability of die-casting, plastic or from several, permanently connected elements, preferably made of fiber-reinforced plastic Escalator level 1 will be improved.
  • the support bearings 14 have for inclusion the connecting axis 8 bearing holes, in which Bearing bushes 9 inserted and by means of clamping elements 10 are secured.
  • bearing openings 7 Similar bearing openings 15, in which also bushings 9 used and by means Clamping elements 10 are secured, may be provided.
  • the Bearing openings 15 are semicircular and opened like a fork, the opening angle smaller than Is 180 °.
  • connection axis 8 It is within the scope of the invention more than that in FIG shown two support bearings 14 or just one Provide support bearing 14. It is also possible Connections of the support bearings 14 to the connection axis 8 also run without bearing bushes 9. It is also in the Framework of the invention that the design of the positive connection from the shown Embodiment may differ.
  • the invention can not only be from one Pieces of escalator steps or moving walk pallets, but also for those that consist of several parts are composed and / or of other materials exist, be applied.
