Definitions

  • the invention relates to an escalator or moving walk, according to the preamble of claim 1.
  • Such escalators or moving walks are known from EP-A2-1 088 783, but also, for example, already known from DE-OS 14 56 402. While in massive balustrades regularly deflecting wheels are used for the deflection of the handrail on the balustrade heads, in transparent balustrades, ie balustrades with a balustrade glass pane, a construction has prevailed in which deflecting rollers replace the deflecting wheels.
  • the pulleys are distributed essentially semicircular and lead and store the handrail in the area of the balustrade head.
  • wedge handrail In the area of so-called traffic systems in railway stations and in the outdoor area, a wedge handrail is increasingly being used. If the wedge handrail was initially used in conjunction with handrail drives in the balustrade head, it is increasingly being used in escalators with underfloor drives.
  • the invention has the object, an escalator or moving walk according to the preamble of claim 1, which are further improved in terms of the durability of the wedge handrail without the possibility of using transparent balustrades would be prevented.
  • the realization of wedge rollers instead of ball bearings results in a large number of advantages.
  • the significantly larger diameter of the wedge rollers relative to the ball bearings has a positive effect, so that the flexing work on the system between the outer surfaces of the ball bearings and the inner surfaces of the handrail is avoided.
  • the curvature of the outer peripheral surfaces of the wedge rollers is more closely approximated to the course of the handrail when passing over the balustrade head.
  • they are provided on the side edges of the outer peripheral surfaces both inside, ie towards the keyway, as well as outwardly, with a chamfer or a small radius. This measure also serves to reduce the notch effect against the elastomer of the wedge handrail.
  • the wedge handrail runs on an axis extending between the inner and outer Balustradenhcade.
  • the bearing surfaces of the wedge rollers are quite far outside.
  • the lever arm is best intercepted in the lateral force application and the tilting tendency of the wedge handrail is eliminated.
  • the inventive design also benefits from the advantage that the wedge surface of each wedge roller serves as a backup system or security system. According to the invention, it is advantageous if there is no plant in normal operation to keep the friction low. If, however, the user is strongly supported on the side of the handrail, there is a short-term investment, which also allows a large-area support, so that the wedge handrail is not overcharged.
  • the end face of the wedge of the wedge handrail remains out of engagement with the inner peripheral surface of the wedge roller. This ensures that not by the different relative velocities inner peripheral surface - outer bearing surface - inner surface of the wedge handrail and end face of the wedge forcibly generated friction arises.
  • the inner peripheral surface of the wedge also has a very small diameter, so that the wedge can be accommodated in its full height in the keyway of the wedge roller.
  • an escalator 10 has a wedge handrail 12, which has a wedge 14 at a central location.
  • the wedge 14 is guided over inventive Be wedge rollers 16 at the head of a balustrade 19, wherein in Fig. 1, only the guide section 20 for the handrail of the balustrade 18 is Darge presents.
  • the balustrade has a glass pane, not shown, which is received in a groove 22 of the guide profile 20.
  • the wedge rollers 16 act as pulleys to guide the wedge handrail over the balustrade head.
  • the wedge rollers 16 have on their outer periphery bearing surfaces 24 and 26, the inner surfaces 28 and 30 of the handrail 12, the wedge 14 adjacent support and guide. Between the bearing surfaces 24 and 26, the keyway 32 of the wedge roller 16 extends.
  • the keyway 32 has wedge inclined surfaces 34 and 36 and an inner peripheral surface 38. These surfaces remain in normal operation out of engagement with the wedge 14, so that each a uniform gap remains. Only with a particular lateral load the lateral inclined surfaces of the wedge 14 come into contact with the keyway inclined surfaces 34 and 36th
  • the wedge roller 16 is mounted on a fairly small double ball bearing 40.
  • the axis 42 extends between webs 44 and 46 of the guide profile 20.
  • the guide plates 48 and 50 may be in one piece or separately, wherein the wedge rollers 16 are each received in apertures in the barrel of the one-piece.
  • the running height of the wedge handrail 12 results practically by the radius of each wedge roller 16, but not by their diameter. This already ensures that a slender appearance can be achieved with a comparatively large diameter for the wedge roller 16. Below the wedge roller 16, a non-illustrated cover is attached, which covers the wedge roller 16.
  • bearing surfaces 24 and 26 each have either a slight radial rounding or chamfer at their edges. It is understood that instead of the solution presented here, modifications are conceivable without departing from the scope of the invention.
  • an additional support may be provided in the guide profile below the wedge rollers 16.
  • the webs 44 and 46 practically a kind of U-shaped Form channel in which another U-profile for forming the guide plates 48 and 50 is added.
