Definitions

  • the invention relates to a handrail guide for escalators and moving walks, according to the preamble of claim 1.
  • the handrail of the escalator or moving walk must be well guided.
  • the tension to be introduced into the handrail should be applied evenly.
  • the flexing work of the handrail specified by the handrail guidance should not be increased further if possible by the rollers.
  • Such a handrail guide is quite complex to manufacture. Nevertheless, repairs to the individual rollers are required on a case-by-case basis, and these are also difficult to carry out.
  • the invention has for its object to provide a handrail guide according to the preamble of claim 1, which combines less susceptibility to repair with less repair effort, although the heating of the handrail does not increase at least.
  • a particular advantage of the handrail guide according to the invention is the easy assembly and interchangeability of the rollers.
  • the support strip according to the invention allows two rollers to be supported on an axle with sufficient stability, the fact that the guide profile is essentially U-shaped or W-shaped anyway due to the system can be used to advantage.
  • the axis or the support strip is automatically held laterally in the guide profile and supports the handrail in the vertical direction, resting on the central web.
  • the symmetrical support of the handrail by the rollers is particularly favorable; in this way, a transverse walk, as could occur due to excessive handrail tension in the proposed solution, is reliably avoided.
  • rollers in the symmetrical arrangement according to the invention essentially only have to absorb radial loads, while in the asymmetrical arrangement with rollers arranged alternately in the left and right U-shaped grooves, shear forces are also obviously introduced, for the absorption of which the usual Ball bearings used are less suitable.
  • roller bearings can also be used as roller bearings.
  • the support strip is made from a flat band, which can consist, for example, of flat steel, deep-drawn sheet metal or similar material.
  • cuts or punchings running in the longitudinal direction of the band are made to be aligned parallel to one another and then the middle, web band thus formed is bent downward to the lower round link and the two outer band webs thus formed are bent upward to the two lateral round plates .
  • the support strip according to the invention is set somewhat under tension during assembly in the guide profile, so that the round link bearings each clamp the axes.
  • the support strip is angled in a U-shape and has corresponding bores on its side legs for receiving the roller axles.
  • the lateral support of the axle for the rollers is carried out on the inside on the outer legs of the W-shaped guide profile.
  • the inner bearing shells of the roller bearings used then in turn support them laterally on their side facing the support strip.
  • the support strip if desired, always centered on the guide profile with centering devices can be held.
  • fastening means such as screw connections can be used, for example, or the central web of the guide profile can be provided with punched-out and erectable tabs which can enter corresponding centering openings in the support strip.
  • the support strip according to the invention is provided to attach the support strip according to the invention only in the area of the balustrade head and to fasten it there at the end, for example by means of corresponding screw connections. It is also advantageous here to provide the arrangement of the rollers essentially uniformly and to thin out the number of rollers per unit length towards the end of the balustrade head. This enables a particularly favorable adaptation to the load conditions that occur.
  • the handrail guide 10 shown in FIG. 1 has a guide profile 12 over which a handrail 14 is guided is.
  • the guide profile 12 is supported on a balustrade glass pane 16, which is part of a balustrade, not otherwise shown.
  • a support strip 18 is received in the space between the guide profile 12 and the handrail 14, which supports rollers 20 and 22 via an axis 24.
  • the essentially conventionally designed handrail 14 thus rolls on the rollers 20 and 22.
  • the handrail 14 is also bent inwards at the end in a known manner.
  • the axis 24 is - as can be seen more clearly from FIGS. 2 and 3 - centrally received in a round link bearing 34 which is formed in the guide profile 12 by a corresponding deformation, expediently a cold deformation.
  • the round plate bearing 34 has a central plate 36 which lies flush on a central web 37 of the guide profile 12. Furthermore, the round plate bearing 34 has two lateral round plates 38 and 40 which overlap the axis 24 and are likewise formed in the support strip 18.
  • the rollers 20 and 22 each have inner bearing shells 50 and outer bearing shells 52.
  • the inner bearing shells 50 have a somewhat larger width, so that they can be supported laterally on the guide profile 12 and the support strip 18 on both sides of the grooves 42 and 44, respectively.
  • the outer bearing shells 52 can run freely with ball bearings and allow the handrail 14 to roll off.
  • a round link plate bearing 34 consists of the two side round links 38 and 40 and the central round link 36.
  • the side round link 38 is separated from the central round link 36 by a punch 54
  • the lateral round link 40 is separated from the central round link 36 a punch 56 separated.
  • a correspondingly cut strip of deep-drawn sheet metal is first provided with the equally spaced punchings 54 and 56 and then the desired round profile is formed with a deep-drawing tool or a small press.
  • the thermoformed sheet is shortened in length, but without creating any particular internal stresses. Accordingly stress relief annealing is not required.
  • the round link bearings 34 designed in this way are then equipped with axles 24, on which a roller 20 or 22 is possibly already attached on one side.
  • the inner bearing shells 50 have only a very slight oversize with respect to the axis 24, so that the roller 20 and 22 which has been plugged in once does not fall off, but can be pulled off with the appropriate effort.
  • FIG 3 shows the manner in which the round plates 36 on the one hand and 38 and 40 on the other hand each form a round plate bearing 34. It can be seen that the surface covered by the round tabs in the lateral projection is almost circular and is well suited for accommodating the cylindrical axes.
  • the invention is not limited to the illustrated embodiment.
  • This configuration enables the use of narrow inner bearing shells 50, so that standard ball bearings are used as rollers 20, 22.
  • a support strip according to the invention 18 not limited to balustrade heads.
  • corresponding support strips can be used over the entire course of the escalator or the moving walk - with customized roller distribution - and can even be used on curved escalators.
