Definitions

  • the present invention relates to an escalator step provided with a resin-made and translucent riser, and an escalator fitted with this step.
  • a step tread on which a passenger gets and a riser corresponding to the riser of a staircase are formed by aluminum die casting, and the surfaces thereof are painted and colored.
  • Such a step has a problem in that the cleat portions of the step tread and riser are worn out by the long-term use, and the paint on the surfaces peels away.
  • the resin-made step tread has an advantage that color loss and marred appearance do not take place even if it is used for a long period of time because the resin material itself can be colored and relatively free coloring can be performed. Also, the resin-made step tread has an advantage that various features such as soft ride comfort (tread comfort) and lightweight, which have not been offered by the step tread made by aluminum die casting, can be offered by making the step tread of a resin.
  • an escalator step has been proposed in which after a central portion of a riser, for example, formed by aluminum die casting has been removed by machining, a metallic support plate is fixed so as to close the opening from the back surface side of riser, and a sign indicating means and a translucent cover plate are provided on this support plate (for example, refer to Patent Document 1).

Also, in the above-described assembled state, the substantially rectangularly shaped opening 32 rimmed with the reinforcements 28 to 31 is formed.
  • the riser 19 since the surface 26 side of the riser 19 is manufactured of translucent FRP, a good appearance can be given to the riser 19. Therefore, the riser 19 itself serves as an indicating means. For example, an advertisement such as a guidance in a shop and a logo is displayed by the indicating element 38.
  • the riser 19 can be used for various applications: for example, the riser 19 can play a role as a part of interior so as to match the escalator with the building, or the riser 19 can be used as an attention exciting means for the safety of escalator by lightening the passenger's feet. Also, comparing with the conventional example, since the whole of the surface 26 of the riser 19 is formed of FRP, there is offered an advantage that there is no fear of color loss and marred appearance when the riser 19 is used for many years.
  • the riser portion requires predetermined strength and rigidity, so that if the whole thereof is attempted to be manufactured of FRP, the need for greatly increasing the thickness thereof arises and the cost increases, and also it becomes difficult to achieve the stability of dimensional accuracy.
  • the metallic reinforcing member 20 is provided between and beyond the brackets 18 arranged in the right and left direction, and the FRP-made riser 19 is fixed to the metallic reinforcing member 20, so that the riser 19 can be formed by a thin sheet member, and hence the production efficiency can be improved and the cost can be reduced.
  • the predetermined strength and rigidity can be secured by a simple construction. Also, as described above, by fixing the parts by using fasteners such as screws and bolts and an adhesive, the reliability of the step 12 can be secured.
  • the riser 19 does not require high wear resistance unlike the tread 23 of the step tread 17, which is always treaded down by the passenger. Further, since the riser 19 does not correspond to a portion on which the passenger gets, the performance of preventing slip, which is required by the tread 23 of the step tread 17, is also not required. Inversely, from the viewpoint of preventing the passenger's foot from being caught between the steps 12, a low friction coefficient is required. Therefore, the surface of FRP material for the riser 19 need not be coated to obtain improved wear resistance and high friction coefficient. Therefore, if only the riser 19 is formed of FRP, the lightweight and improved appearance can be attained without waste.
  • step 12 having the above-described construction is used for an escalator
  • all of the steps may be the steps 12 having the above-described construction.
  • some of the steps may be the steps 12 having the above-described construction, and other steps may be steps provided with the conventional aluminum die-cast riser.
  • any configuration can be provided: for example, by affixing the indicating elements 38 having no translucency to the back surfaces of the risers 19 of some steps, only some steps are provided with any indication.
  • the riser can be provided with a unique appearance, whereby the riser can be used for various applications. Also, by supporting the FRP-made riser on the brackets at both sides via the metallic reinforcing member, the predetermined strength and rigidity can be secured, and also by constructing the riser into a thin plate shape, improved production efficiency and low cost can be achieved.
