Definitions

  • the invention relates to an escalator step and a method for its production.
  • Escalators are well known and efficient means of transporting people. Escalator steps are designed as one-piece or multi-part components and are usually made by a casting, extrusion or forging process, but also from deep-drawn parts. Mixed forms are also known which have both cast parts and sheet metal parts. Escalator steps of the aforementioned type are, for example, in the WO2015 / 032674 A1 disclosed.
  • the top of the escalator step has a tread pattern in the form of a series of parallel ribs or webs running from the front to the rear. The ribs thus extend in the intended direction of movement of the escalator step.
  • Their setting element also has ribs which usually connect to the ribs on the top. Furthermore, the ribs are dimensioned for engagement in the comb structures arranged at the entry areas of the escalator or moving walk.
  • An escalator generally has a structure or truss with two deflection areas, between which the step belt is guided all around.
  • WO2015 / 032674 A1 Escalator steps that have separate tread plates, the tread plates being arranged by means of projecting hooks on a step skeleton made of sheet steel or on an extruded tubular body.
  • WO 2009047146 A1 discloses a similar escalator steps.
  • Escalator steps of the aforementioned type or their step skeleton or tubular body convert a largely trapezoidal cross section transversely to the ribs and grooves of their tread elements, the escalator steps being formed from thin walls and beams. As a result, they have a very large volume with a small mass. This complicates the transportation from the place of manufacture of the escalator step to the assembly location where the escalator step is installed in an escalator. Only a few escalator steps can therefore be transported in a standard container in relation to the maximum permitted transport weight.
  • the object of the present invention is therefore to provide escalator steps that are optimized for transport from the manufacturing site to the assembly site.
  • an escalator step which has a one-piece step body with a step element section and a setting element section, the step element section and the setting element section forming an L-shaped cross section of the one-piece step body. Furthermore, the escalator step has two side walls which can be arranged on both sides of the one-piece tread body. Furthermore, the escalator step contains at least one support profile which can be arranged between the side walls.
  • the one-piece tread body, the side cheeks and the support profile are designed as plug-in parts and therefore have plug connections. By means of these plug-in connections, the support profile with the side cheeks and the one-piece tread body can be plugged together at least with the side cheeks to form an escalator step.
  • the invention is based on the finding that, for manufacturing reasons, the plug connections can have play in them and thus have a narrowly limited freedom of movement.
  • the stabilizing property of the L-shaped cross section of the one-piece tread body is used in particular. That means that for reasons of stability the Setting element section and the tread element section are integrally connected to one another and are therefore designed as a one-piece tread body.
  • the plug connections are preferably plug-in connections between the one-piece step body and the side cheeks, between the side cheeks and the support profile and between the one-piece step body and the support profile.
  • the plug connections also limit each other in their freedom of movement as a result of play, so that an entirely rigid escalator step can be produced by simply plugging the plug parts together.
  • the escalator step can be disassembled into individual parts in a space-saving manner.
  • the escalator step still has to be put together at the installation site, because of the plug connections this can be done with little effort.
  • the assembly of these parts can also be done fully automatically by means of robots or automatic assembly machines due to the concept of plug-in parts.
  • the plug connections also enable an extremely stable, in particular stable connection of the one-piece tread body to the side cheeks and the support profile. There is preferably no excessive play in the plug connections.
  • the plug connection can even have a sliding fit or a slight press fit. If the plug connection can only be plugged together in a single mounting direction, it has a high positioning function with only a single degree of freedom. This helps to avoid assembly errors.
  • the mounting direction of the individual plug connections can be arranged orthogonally to a main loading direction of the respective plug connection, so that the greatest force acting in the plug connection can be absorbed by the positive connection of the plug connection.
  • securing means which are used to secure the plug connection are largely relieved and can be of very small dimensions. If necessary, a securing means can be dispensed with for individual plug connections.
  • the mounting direction can be arcuate, so that the plug connection can be assembled by means of a pivoting movement.
  • the mounting direction can also be linear, so that the plug connection can be joined together by means of a linear movement.
  • Each of the plug-in connections has at least one projection and at least one recess which is form-fittingly matched to this projection.
  • Each of the plug-in connections is always divided into two plug-in parts, the recess being formed on a plug-in part of the escalator step and the projection to be inserted into this recess being formed on a further plug-in part adjacent to the recess in the assembled state.
  • At least one of the plug connections is preferably secured by a securing means.
  • a material locking means such as a polymer adhesive, by soldering or by welding.
  • the at least one plug connection can also be secured in a form-fitting manner by, for example, a split pin, a rivet, a pin or a screw, which protrude through the material forming the recess and the projection, orthogonal to the mounting direction.
  • snap connections are also possible, which are formed parallel to the plug connection.
  • Other possible positive locking means are caulking or clinch connections.
  • the securing means prevents the secured plug connection from becoming loose.
  • a combination of cohesive and positive locking means can be used on the same escalator step or even on the same connector. Since the plug connections are preferably designed in such a way that the greatest force acting in the plug connection is absorbed by the positive connection of the plug connection, the securing means can be dimensioned very small or can hardly be designed to transmit loads.
  • the plug-in parts can basically be made of different materials and using different manufacturing methods. To avoid reworking the projections and recesses, however, the plug-in parts are preferably light metal die-cast parts. Aluminum alloys are particularly suitable as casting materials. Of course, at least two plug connections can be provided between two adjacent plug parts to be joined. Several plug connections increase the mechanical stability between the two joined parts.
  • an emergency guide hook can be formed on at least one of the side walls. This emergency guide hook can project underneath an emergency guide rail or a running rail of an escalator in which the escalator step is used and thus prevent the escalator step from being lifted off the running rail.
  • the first and second traction means are usually link chains provided with rollers.
  • the step belt is arranged in a known manner all around in an escalator.
  • the escalator step described above is manufactured and assembled at least with the following steps: First, the one-piece tread body, the side cheeks and the support profiles required for the production of the escalator step are produced as plug-in parts, for example by means of a light metal die-casting process, recesses and projections of the plug connections being formed on the plug-in parts. Then the plug-in parts of the escalator step are plugged together to form an escalator step by means of the plug-in connections formed thereon, by first carrying the support profile between two Sidewalls arranged, plugged together and then the one-piece tread body with the sidewalls and the support profile arranged between them is plugged together.
  • plug connections After plugging together, at least one of the plug connections is secured by means of a positive or material locking means. If necessary, additional attachments such as drag rollers, emergency guide hooks, sliding guide elements and the like are attached to the escalator step to complete the escalator step.
  • escalator steps are manufactured in large numbers in a manufacturing plant and then shipped to escalator assembly plants worldwide. Since, according to the present invention, the main components of the escalator step are plug-in parts, these plug-in parts can be packaged and transported in a very space-saving manner. This results in an excellent utilization of the existing transport volume, for example a transport container as defined in the ISO standard 678 and can be transported by container ships, the train and trucks.
  • the escalator steps are produced according to the invention in the form of plug-in parts, the plug-in parts of an escalator step comprising at least one integral, L-shaped step body, two side walls and a support profile.
  • the one-piece tread bodies are stacked one inside the other and packed in transport boxes in such a way that their tread element sections and each of their setting element sections rest against one another.
  • Existing cavities in the transport boxes with the one-piece step bodies can be filled with support profiles and side panels. If necessary, additional transport boxes must be filled with support profiles and side panels.
  • the one-piece step body, the side panels and the support profiles can also be packed separately in transport boxes.
  • the transport boxes are preferably matched to the loading mass of the ISO containers, so that as little transport volume as possible is lost.
  • the plug-in parts are unpacked at the installation location and then used to connect them to the escalator steps using the plug-in connections.
  • the escalator step is assembled by first placing a support profile between two side walls, plugging them together and then an integral step body with the side walls and the one in between arranged support profile is plugged together. Then at least one of the plug connections of the assembled escalator step is secured.
