Definitions

  • the invention relates to an escalator step and to a method for the production thereof.
  • Escalators are well-known and efficient means of transporting people. Escalator stages are designed as one-piece or multi-part components and usually produced by a casting, extrusion or forging process, but also from deep-drawn parts. Furthermore, mixed forms are known which have both castings and sheet metal parts. Escalator steps of the aforementioned type are disclosed for example in WO2015 / 032674 AI.
  • the top of the escalator step has a tread pattern in the form of a series of parallel ribs or ridges extending from the front to the back. The ribs thus extend in the intended direction of movement of the escalator step.
  • Its setting element also has ribs, which usually connect to the ribs of the top. Furthermore, the ribs are dimensioned for engagement with the comb structures arranged at the entrance areas of the escalator or the moving walkway.
  • An escalator usually has a supporting structure or framework with two deflection areas, between which the step belt is guided circumferentially.
  • Forming tools for escalator stages are very expensive. Furthermore, the size of these moldings, in particular in the region of the ribs and grooves, can lead to casting-technical problems, namely to voids formation, so that to avoid them an elaborate tempering of the molds is required.
  • WO2015 / 032674 AI proposes escalator steps, the have separate tread plates, wherein the tread plates are arranged by means of subordinate hooks on a step skeleton made of sheet steel or on an extruded tubular body.
  • Escalator steps of the aforementioned type, or their step skeleton or tubular body convert transversely to the ribs and grooves of their tread elements a largely trapezoidal cross-section, the escalator steps are formed of thin walls and straps. As a result, they have a very large volume at low mass. This complicates the transport from the place of manufacture of the escalator stage to the installation site where the escalator step is installed in an escalator. In a standard container thus comparatively only a few escalator stages can be transported in relation to the maximum permitted transport weight.
  • the object of the present invention is therefore to provide for the transport from the place of manufacture to the assembly optimized escalator stages.
  • an escalator step which has a one-piece foot body with a tread element section and a setting element section, wherein the tread element section and the setting element section an L-shaped
  • the escalator stage has two side cheeks, which can be arranged on both sides of the one-piece tread body. Furthermore, the escalator stage includes at least one support profile, which can be arranged between the side cheeks.
  • the invention is based on the finding that the connectors
  • the stabilizing property of the L-shaped cross section of the one-piece tread body is utilized. That means that for stability reasons the Setting element portion and the tread element portion integrally connected to each other and therefore formed as a one-piece tread body.
  • the escalator step can be transported in disassembled parts to save space. Although the escalator stage still has to be assembled at the installation site, this is easily possible due to the connectors with the least possible effort.
  • the assembly of these parts can be done by the conception as plug-in parts fully automatically by means of robots or automatic assembly machines.
  • the connectors also allow a very stable, in particular dimensionally stable connection of the one-piece Tritt stresses with the side cheeks and the support profile. Preferably, there is no excessive play in the connectors.
  • the connector may even have a sliding fit or slight interference fit. If the connector is assembled only in a single mounting direction, this has a high degree of positioning function with only a single degree of freedom. This helps prevent assembly errors.
  • the mounting direction of the individual connectors may be arranged orthogonal to a main load direction of the respective connector, so that the largest force acting in the connector force by the positive connection of
  • Plug connection is receivable.
  • securing means which are used to secure the connector, largely relieved and can be very small dimensions.
  • the mounting direction may be arcuate, so that the connector is connected by means of a pivoting movement.
  • Assembly direction also be linear, so that the connector by means of a
  • Each of the plug-in connections has at least one projection and at least one recess that is matched in a form-fitting manner to this projection.
  • Plug connections is always divided into two plug-in parts, wherein the recess is formed on a plug-in part of the escalator step and the projection to be inserted in this recess is formed on a further, in the assembled state, the plug-in part with the recess adjacent plug-in part.
  • At least one of the connectors is secured by a securing means.
  • a securing means such as a polymer adhesive, by soldering or by welding.
  • the at least one plug-in connection can also be secured in a form-fitting manner by, for example, orthogonal to the mounting direction, a split pin, a rivet, a pin or a screw, which project through the material forming the recess and the projection.
  • snap connections are possible parallel to the
  • Plug connection are formed.
  • Other possible form-locking securing means are caulking or clinch connections.
  • the securing means prevents the secured plug connection from coming off.
  • a combination of cohesive and positive locking means can be used at the same escalator level or even on the same connector. Since the connectors are preferably designed so that the largest in the
  • the securing means can be very small dimensions or hardly configured load-transmitting.
  • the plug-in parts can basically be made of different materials and by means of different manufacturing methods. However, to avoid reworking of the projections and recesses, the male parts are preferably light metal die castings. As cast materials are particularly suitable aluminum alloys. Of course, at least two plug connections can be provided between two adjoining plug-in parts to be joined together.
  • an emergency guide hook may be formed on at least one of the side cheeks.
  • This emergency guide hook can underlay an emergency guide rail or a running rail of an escalator, in which the escalator step is used, and thus prevent lifting of the escalator step from the running track.
  • attachment areas listed below may be formed on the side cheeks or on the one-piece foot body for attachment of attachment parts:
