Definitions

  • the invention relates to a step for an escalator, wherein the step is formed as a one-piece light metal die-cast part comprising a tread plate, an apron, at least one transverse rib, guide eyes, wherein the guide eyes are fastened exclusively to the apron and drive eyes.
  • WO 2009/047144 A1 discloses a step assembled from deep-drawn sheets. This has the disadvantage of a complex assembly which has high costs.
  • the DE 299 09 808 U1 discloses a step made of glass fiber reinforced plastic having a plurality of ribs and reinforcements for stiffening.
  • the EP 2 173 652 B1 discloses a tread element which is made of die-cast aluminum and which is integrally formed except for the strips.
  • the JP 2012 201485 A discloses a step for an escalator, wherein the step is formed as a light metal die casting, including a tread plate, an apron, guide eyes, the guide eyes are fastened exclusively to the apron and drive eyes, the drive eyes in each case exclusively with a connecting web attached to the step or are arranged.
  • the disadvantage of the above-mentioned tread element is that a high cost of materials due to the present bracing to achieve the required strength and rigidity is necessary.
  • the drive eyes are fastened or arranged exclusively with a connecting web on the step.
  • the present invention is characterized in that material or casting material can be saved in the production of the stage by can be dispensed with connecting or stiffening struts.
  • the previously known stages usually have a connecting web between drive eye and guide eye in order to obtain the required rigidity as well as strength of the stage.
  • the inventive step is achtmetalldruckgussteil which is formed from one piece.
  • the step includes a tread plate, an apron, at least one transverse rib, the transverse rib preferably located at the bottom of the tread plate and intended to provide the required stability and strength of the tread plate.
  • the transverse rib preferably extends between the two connecting webs of the drive eyes or up to the edge regions of the step.
  • the step includes guide eyes, which are arranged or molded exclusively on the apron. The guide eyes are arranged in the two edge regions of the step.
  • the inventive step has in each case on both sides of the step, seen in the direction of travel, a drive and guide eye on or in the edge regions of the step.
  • the drive eye is connected to the drive chain of the escalator.
  • the guide eye is used with a role attached to the leadership of the stage and so the escalator.
  • the drive eye or the two drive eyes, which includes a stage, are connected to the stage exclusively via a respective connecting web.
  • the drive eyes are stabilized by any other web, they are each arranged and fixed only by means of a connecting web to the stage.
  • the drive eye can be designed as a closed ring as well as unilaterally open ring segment.
  • the connecting web is arranged to the drive eye on the tread plate of the step, especially preferably on the underside of the tread plate.
  • the stage is symmetrical, which is why it is not always mentioned specifically that the stage has two drive eyes and guide eyes as well as connecting webs.
  • the drive eye and the guide eye of the respective edge region of the step are preferably in alignment with the escape running in the direction of travel of the step.
  • the guide eyes are attached to the apron on the step or formed on it. Due to the fact that the eyes are connected to the step in one orientation only and have no further braces and none Strut between tread plate and apron, the step is open towards the bottom across the entire width.
  • This open design of the stage allows a shortening of the cycle times during casting, as a result of which, the mold or the casting tool can be made simpler and in the best case can even be formed by only two half-shells to form the stage after the casting process. This means that additional slides on the casting tool can be dispensed with, which results in a shortening of the cycle time.
  • the step preferably has reinforcing ribs in the edge regions.
  • the reinforcing ribs are intended to serve the rigidity and strength of the step. It is advantageous if the reinforcing ribs lie in the same alignment with the drive and guide eye.
  • the reinforcing ribs run along the inside of the skirt and the underside of the tread plate and serve to increase the stability of the step and make it impossible for the tread plate to buckle with respect to the skirt.
  • the reinforcing ribs formed on the skirt and tread plate have a radius in the transition from the area of the skirt to the area of the tread plate. It has proven advantageous that the reinforcing rib should have a minimum height of 8 mm.
  • the reinforcing rib may also have different heights in the different regions, that is, for example, the height of the reinforcing rib along the underside of the tread plate may be 10 mm and in the Area of the inside of the apron only 8 mm, of course, other combinations are possible.
  • Fig. 1 shows a three-dimensional view of an inventive step 1 for an escalator.
  • Stage 1 is designed as a one-piece light-alloy die-cast part, whereby high completion costs for the individual stages can be avoided.
  • the step 1 includes a tread plate 2, a skirt 3, at least one transverse rib 4 for stiffening the tread plate 2, wherein the transverse rib 4 is preferably arranged on the underside of the tread plate 2, guide eyes 5, wherein the guide eyes 5 are arranged exclusively on the skirt 3 ,
  • the stage 1 also includes drive eyes 6, which are driven by means of the chain of an escalator, wherein the drive eyes 6 of the stage 1 are respectively arranged in the two edge regions 9 of the stage 1.
  • the drive eyes 6 are connected by means of a respective connecting web 7 with the stage 1 or formed on the tread plate.
  • Fig. 2-4 is the Anformung of the eyes 5, 6 clearly visible by the rotated representation of level 1.
  • the drive eyes 6 are preferably integrally formed on the underside of the tread plate 2.
  • the drive eyes 6 and guide eyes 5 at the respective edge region 9 of the stage 1 are preferably in alignment.
  • the drive and guide eyes 5, 6 point but no connecting struts to each other. Since otherwise also no connecting struts between skirt 3 and tread plate 2 is the level 1 is open over the entire width down.
  • This design of stage 1 allows a simpler structure of the casting tool for the production of the stage 1. This can be dispensed with further slide on the casting tool. This shortens the times for forming the stage 1.
  • each reinforcing ribs 8 are arranged in the two edge regions.
  • the reinforcing ribs 8 preferably extend in alignment with the drive and guide eyes 5, 6 of the respective edge region 9.
  • the reinforcing ribs 8 extend along the inside of the skirt 3 and the underside of the tread plate 2.
  • the reinforcing ribs 8 are parallel to the driving device of the stage 1 or an escalator.
  • the reinforcing ribs 8 extend along the skirt 3 and have a radius in the transition to the tread plate 2.
  • the height of the reinforcing rib 8 at least 8 mm.
  • the height of the reinforcing ribs 8 may also be different in the region of the skirt 3 and in the region of the tread plate 2.
  • the skirt 3, the reinforcing ribs 8, the transverse rib 4 and the connecting struts 6 arranged between the transverse rib 4 and the reinforcing ribs 8 form a closed frame, preferably on the underside of the step plate 2, whereby the required stability and strength of the step is achieved.
