Definitions
- the present invention relates to an escalator step or a moving walk pallet according to the preamble of claim 1.
- Such an escalator step or moving walk pallet is known for example from EP-A2-945 391.
- This escalator step or moving walk pallet essentially consists of Plastic, namely from a glass fiber reinforced plastic.
- suitable structural measures like that Realization of a lattice structure can be the strength in Ratio to the weight of the escalator step compared to before increase known solutions significantly.
- the generation Such a lattice structure from the manufacturing form quite complex. It is particularly suitable for the use of the Injection molding technology and less for the realization of a corresponding die casting mold.
- plastic steps cannot be used in all Use use cases equally well.
- Lifetime of plastic steps in the case of strong temperature fluctuations limited so preferred outdoors metallic steps are used.
- metallic steps a construction according to EP-0 945 391 does not come or only considered in special exceptional cases.
- the above mentioned solution used to stiffen the plastic existing step or pallet a hollow metal profile that in the plastic step or pallet is integrated.
- plastic and metal on the other hand, have a different one Coefficient of thermal expansion, so that the operation at changing temperatures the risk can arise that releases the metal profile in the recess in question, so that special measures must be taken that it is not shifted sideways.
- elastomer for example or other suitable, more elastic materials
- To such a solution is not particularly weatherproof.
- the invention has for its object a Escalator step and a moving walk pallet according to the Generic preamble of claim 1 to provide the Strength / weight ratio without limitation Lifetime or usability and also without high costs is improved.
- the base body made of foam metal in proportion to its weight has particularly good strength, but still none elaborate truss structure must be generated in order to To be able to cast the base body. Rather, it is preferred that Pour the base body so that it is in the melt gas evolution is sustained while the The melt solidifies.
- Metal powder such as Aluminum powder and a gas-releasing blowing agent be compacted.
- the foam metal is also quite pressure stable, so that it is particularly good as Support body especially suitable for changing support loads is. Escalator steps and moving pallets are in subject to changing support loads.
- the tread surface and possibly also the riser of the escalator step is kept foam-free.
- the step plate itself be prefabricated as a solid piece of aluminum, namely in a thickness of for example 1 to 5 mm and in particular about 2 to 3 mm, and the foam metal body can these are cast on. It is understood that any other types of connection between body and Step plate, also for example via an intermediate plate possible are.
- the advantage of such a solution is that the crush resistance of solid aluminum with the Weight and stiffness advantages of foam aluminum can be combined.
- the attachment of the base body on the tread plate, which as intimate Connection is formed in a kind of sandwich construction strength increases. This behavior makes itself felt particularly noticeable, although in the area of Riser an intermediate plate is formed.
- the bottom The step or moving walkway pallet can be advantageous by the axles carried on the drive chains are stiffened be, so that there is an overall box-shaped border for gives the basic body.
- stiffening ribs can be according to the invention be designed in a simple form, so that the Corresponding tendency to dirt accumulation in inside corners is less.
- a covering with rib contour in the extrusion process is produced and rolled onto the intermediate plate. hereby results in a particularly simple production, because the tread surface can be extruded into Generate any length inexpensively, it only is required, the light metal strips produced in this way cut to length as needed, and then more appropriate Way to fix on the intermediate plate. Even if the Fastening by rolling is preferred, it is understood that any suitable other measures for attachment too are suitable.
- the riser could also be used in the same way be produced and applied.
- the training the arch shape is the training the arch shape, however, essential.
- the melting point of the alloy used to produce the foam metal slightly lower than the melting point of the tread plate and if necessary, the intermediate plate. This ensures that by foaming with suitable temperature selection the tread plate and / or the base plate are not deformed.
- the escalator step 10 shown in the figure has in the illustrated embodiment a tread plate 12 and Riser 14, which extend in a manner known per se.
- the tread plate 12 is like the riser 14 with Provide ribs 16 which extend outward / forward.
- On a surface 18 is formed on its underside. Adjacent An inventive one extends to the surface 18
- Base body 20 made of foam metal. According to the invention for this an aluminum / magnesium alloy used that is powder metallurgical is made by using a compacted mixture of metal powder and gas-releasing Propellant.
- the base body 20 extends in a wall thickness 22 from 10mm, it being understood that the wall thickness in wide Areas can be adapted to the requirements.
- ribs 24 As part of the base body, there are also ribs 24 as a support structure trained in a conventional manner. The ribs 24 extend over the extension at fairly large intervals the escalator step.
- the underside of the essentially triangular base body 20 are adjacent fastening eyes 26 and 28th trained, depending on the application, also with full metal can be reinforced.
- the outer rings of are preferred here rather wide bearings with foam.
- Through eyes 26 and 28 extend in a conventional manner axes 30 and 32 connected to the two drive chains of the escalator are.
- the wall thickness in the area of the eye 28 is for the Base body 20 made of foam metal so chosen that the base body there extends up to axis 32 and in this respect one Support over the entire length of the escalator step guaranteed.
- any suitable one according to the invention Adaptation to special design features is possible. So can for example the area of riser 14 without solid material be designed. This area is less polluted, and created by the contact of the metal foam on the casting mold a closed surface. In this respect, the foaming can on a tread plate or intermediate plate only in some areas be made, especially in heavily loaded Some areas.
