Definitions

  • the present invention relates to a handrail drive system for an escalator or moving walkway.
  • This has a handrail drive with drive elements and a band-shaped, circumferentially movable handrail.
  • the WO 200435451 A1 discloses a linear drive system for handrails with a multi-spline profile.
  • An essential element of the drive system is a drive belt which has a toothed belt profile on its inside facing away from the handrail. On its outside facing the multi-wedge profile, the drive belt has a counter-profile corresponding to the multi-wedge profile. The drive power is transferred to the handrail by means of this counter profile. Disadvantages of this solution are considerable signs of wear on the wedge profile flanks and the need for pressure rollers that press the multi-wedge profile of the handrail against the multi-wedge profile of the drive belt.
  • a handrail drive system of an escalator or a moving walk which has at least one handrail drive with drive elements and a band-shaped handrail that can be moved around the circumference.
  • the handrail is delimited by an outer contour designed as a gripping surface and by an inner contour which leaves a cavity in the handrail, the cavity being open to the surroundings of the handrail.
  • the handrail drive system is preferably designed as a linear handrail drive system, that is, the handrail in the area the drive elements is essentially guided past them and the drive elements which are in direct contact with the handrail are arranged in one plane.
  • the driving force can be transmitted from the drive elements to the handrail on two opposite side surfaces of the inner contour, with all other forces caused by the transmission of the driving force and acting on the side surfaces being mutually compensated by a complementary design of the side surfaces with the exception of the driving force.
  • the handrail is made from a soft elastic elastomer material and has sliding elements made from a polymer material which is harder than the soft elastic elastomer material.
  • the sliding elements are arranged in sections at discrete intervals along the longitudinal extension of the handrail, with guide elements and / or tooth profiles being formed on the sliding elements.
  • a complementary configuration of the side surfaces is understood to mean a configuration that mutually compensates for all forces acting in the area of the driving force transmission on side surfaces, with the exception of the driving force, so that no additional components such as pressure rollers are required.
  • the two complementary side surfaces are preferably configured mirror-symmetrically to one another. In the case of an operationally circumferentially arranged handrail, this can be, for example, side surfaces arranged in two parallel, vertical planes which mutually support the contact pressure between the handrail and the drive elements necessary to transmit the driving force.
  • the handrail can have a U-shaped or C-shaped cross section along its length.
  • the side surfaces do not necessarily have to be flat surfaces. They can also be concave, convex or prism-shaped, provided they have the complementary design specified above.
  • tooth profiles to which the driving force can be transmitted are preferably formed on the two opposite sides of the inner contour.
  • the inner contour is provided with sliding elements on which guide elements and / or tooth profiles are formed.
  • the guide elements interact with handrail guide means, such as a handrail guide profile or guide rollers, which are stationarily arranged on a balustrade of the escalator or the moving walk.
  • the guide elements can, for example, be guide grooves matched to the handrail guide profile.
  • fabric inlays, sliding friction-reducing surface coatings or sliding elements for example made of a suitable polymer material such as PTFE (polytetrafluoroethylene) or POM (polyoxymethylene) or of a metal such as brass or bronze and the like, can be used as sliding elements.
  • the guide elements are preferably combined with the sliding elements.
  • the handrail or handrail strap is usually made of a soft elastic elastomer material such as SBR (styrene-butadiene rubber), EPM (ethylene-propylene rubber), EPDM (ethylene-propylene-terpolymer rubber), NBR (acrylonitrile-butadiene rubber), which is constant over its length ) and the like, with tension members such as steel wire strands, carbon fibers or aramid fiber strands being embedded in the elastomer material for reinforcement.
  • SBR styrene-butadiene rubber
  • EPM ethylene-propylene rubber
  • EPDM ethylene-propylene-terpolymer rubber
  • NBR acrylonitrile-butadiene rubber
  • the handrail is made of a soft elastic elastomer material and the sliding elements are made of a polymer material that is harder than the soft elastic elastomer material.
  • the harder sliding elements are arranged in sections at discrete intervals along the longitudinal extension of the handrail and are preferably partially embedded in the elastomer material.
  • the guide elements and / or tooth profiles are formed on the sliding elements.
  • the handrail strap or handrail designed in this way has a spine-like structure so that it has alternating hard and soft elastic areas. As a result, the handrail can be bent without any problems and highly stressed areas such as sliding surfaces or guide grooves can be formed on the sliding elements.
  • the sliding elements can be connected to the tension members embedded in the flexible elastomer material.
  • the drive elements of the handrail drive system can comprise at least one circumferentially movable toothed belt.
  • the toothed belt can be in contact with the handrail in order to transmit the driving force to the handrail.
  • the driving force can be transmitted in a purely force-fitting manner, but it is preferably mainly transmitted in a form-fitting manner, in that a tooth profile that is complementary to the toothed belt is formed on at least one of the two side surfaces of the inner contour. Since, as described above, the handrail is provided with sliding elements, the two side surfaces with the tooth profiles can also be formed on these.
  • the drive elements can also comprise at least one transmission gear which engages in a corresponding tooth profile of the side surfaces of the inner contour.
  • a large number of arrangements of the drive elements are conceivable, for example pure toothed belt solutions, pure toothed wheel solutions and combinations of toothed wheels and toothed belts.
  • the toothed belt can be in engagement with its first strand with the first opposite side of the inner contour and with its second strand it can be in engagement with the at least one transmission gear.
  • This arrangement allows the direction of movement or rotation of the second strand to be implemented, so that the direction of rotation of the toothed belt is opposite to the Direction of rotation of the transmission gear is.
  • the transmission gear can be in engagement with the second opposite side of the inner contour.
  • the toothed belt can be guided between at least two gears and be in operative connection with them, so that the two gears have opposite directions of rotation and the first of the two gears is in engagement with the first opposite side of the inner contour and the second of the two gears is in engagement with the second opposite side of the inner contour.
  • At least one balustrade with a handrail guide means or handrail guide profile. At least some of the drive elements can be integrated in the handrail guide means.
  • the drive elements described above can be driven by an angular gear arranged in the handrail guide means and a motor and together form a handrail drive.
  • angular gear arranged in the handrail guide means and a motor and together form a handrail drive.
  • several such handrail drives are used to drive a single handrail, the speeds of which must then be precisely coordinated with one another.
  • the toothed belt can be guided by the handrail guide means through the balustrade, through a balustrade base connecting the balustrade to a supporting structure of the moving walk or the escalator, and around a drive wheel arranged in the supporting structure.
  • the drive wheel can be driven by the step belt or by a motor arranged in the supporting structure.
  • the handrail drive system can be used in an escalator as well as in a moving walkway. These usually have two balustrades, which are arranged on both sides of a step band or pallet band and each have a circumferential handrail. Accordingly, per escalator or moving walk are at least provide two handrail drive systems.
  • the present invention has the particular advantage that the handrail drive system is very small and can therefore be installed at any point on the balustrade.
  • the circumferential arrangement of the handrail means that there is a handrail forwards and a handrail return, whereby the user can hold on to the handrail in the area of the handrail forwards.
  • very different tensile forces act on the handrail, depending on the section. Since the handrail drive system is not tied to the available installation space, it can be installed where the ideal installation location is due to the expected load.
  • the tensile forces in the upper level in the handrail flow are highest when the escalator conveys from the lower level to the upper level.
  • the drive elements are therefore preferably arranged there.
  • FIG. 1 shows a schematic side view of an escalator 1 according to the prior art, with the aid of which people can be transported, for example, between two levels E1, E2.
  • the escalator 1 has a load-bearing structure 2 in the form of a framework, which, for the sake of clarity, is only shown in its outlines.
  • the supporting structure 2 accommodates components of the escalator 1 and supports them within a building. These components include, for example, balustrades 3 (only one is visible due to the side view) which have a handrail 5 arranged around the circumference.
  • the balustrades 3 are connected to the supporting structure 2 via balustrade bases 4.
