Definitions

  • the invention relates to a handrail for a passenger transport device in the form of an escalator or a moving walk.
  • a handrail means a device on (one or) both sides of the escalator or the moving walk arranged balustrade. At this balustrade, a handrail or handrail is guided along at the same speed as the escalator or moving walkway moves. As a result, the handle bar for a person on the conveyor or ascending or descending person provides a support or a handhold.
  • a handrail As an integral part of a passenger transport device - think of public facilities such as train stations or department stores - a handrail has to meet high safety requirements in addition to a high degree of functionality.
  • a handrail on a traction means by means of which it is pulled by a drive through a guide.
  • the guide runs along a balustrade located on (one or) both sides of the escalator or moving walkway.
  • the traction means, but also the handrail itself, must be flexible or consist of links so that a staircase-like circulation around the balustrade can be described. This circulation, consists of various arcs and semicircles or semi-ellipses and wraps of the drive wheels.
  • the publication DE 2 203 178 discloses a handrail consisting of four main items.
  • the first main item would be a traction means. It exists preferably made of a steel strip.
  • a cross-sectionally C-shaped profile which consists of individual segments in its longitudinal direction. The segments are solid but have gaps to describe the curved circulation. These interspaces are formed by a convex end face, which faces in each case a concave (back) side of an adjacent segment.
  • the handrail disclosed in this publication has another, approximately rectangular, small profile. This very short profile in turn has a toothing, in addition, connection receptacles are attached.
  • the tension member between the C-shaped and the approximately rectangular, small profile is clamped.
  • the handrail disclosed in this publication has a gripping strip which encases the C-shaped carrier profile or profile.
  • the leadership of the handrail is thereby inventively integrated into the handle.
  • the handrail can - viewed in cross section - can be reduced in this way to only two parts: A handle and a traction device.
  • the handle bar is injection-molded or cast or injection-molded during production or else extruded in such a way that it encloses the traction means in a form-fitting manner.
  • This form-fitting enclosing can be designed so that the traction means has projections and depressions, which are positively enclosed by the (for example injection-molded) gripping strip and corresponding recesses. But even the pure surface fusion - without the projections and recesses just described - during spraying and / or molding or extrusion or Pultrudieren itself should be understood here as a form-fitting enclosing.
  • the handle bar can be injection-molded, for example.
  • it can be injection molded or cast from a plastic material, which allows a production - in its longitudinal direction - not only from individual segments, but also from a single piece.
  • the traction means must be extremely flexible and allow easy diversion.
  • a preparation into consideration which is already factory-connected at its interface and is delivered as a finished handle strip ring to the installation site.
  • it is also from the outset a production of a ring and not an open handle strip tape into consideration, which must be closed later to a handle strip ring.
  • an assembly on site in question for example by means of an overlapping connection that does not apply and ensures a smooth connection point. The latter is particularly required on the handle bar top, so there is no risk of injury to the transported persons.
  • the handle bar can - seen in its cross section - be made of a single material as a full or whatsoeverquo or hollow or even partially hollow, braced with webs, profile.
  • the material selected here will represent a consensus or a merger of advantageous properties in order at the same time to fulfill the required or desired or desired material requirements as well as possible.
  • the material In the case of a one-piece longitudinal design variant, the material must be flexible in order to be able to describe the curves and curves of the circulation. At the same time, however, it must also be so supple that the bends and the alternating bending stress cause no cracks. In the case of a roller drive, the material must have sufficient resistance to friction, which increases the thrust of the driving Roll / rolls endures.
  • the guide surfaces must be wear-resistant, abrasion-resistant and hard and have good sliding properties.
  • the grip surface must be pleasant to the touch and allow a secure grip.
  • a preferred embodiment variant of a handle according to the invention thus provides better to meet the partially conflicting material requirements by a handle bar was created, which is still integrally formed in its cross section, but consists of a material compound with two, three or more materials .
  • This can be, for example, two or three different types of plastic or plastic variants that are injected in a common injection molding so that, for example, the guide surfaces made of a very abrasion resistant, very good sliding plastic and the remaining cross-sectional profile of the handle made of a flexible and haptic pleasant plastic is.
  • PAS ® -LXY Faigle from Hard / Austria is well suited among other things.
  • a material whose friction coefficient is in a range of 0.05 to 0.35, preferably at 0.10 to 0.15 preference is to be given to using Teflon plastics or polytetrafluoroethylene plastics and / or NANO bonded coatings or NANO sliding plastics or NANO sliding parts or NANO sliding particles.
  • a further preferred embodiment variant of a handle according to the invention provides a material compound of three or more different materials.
  • the guide surfaces may consist of a Teflon sliding material as described above, the base body portion of the handle, however, from one that optimally meets the structural requirements (bending change properties, tensile strength) and the mantle area or deck area of the handle again from a soft and haptic pleasant material.
  • the handle strip body region is preferably formed of a plastic whose flexural strength is in a range of 30 to 185 N / mm 2 , preferably 50 to 95 N / mm 2 , also values of 15 to 30 N / mm 2 are conceivable.
  • haptically pleasant materials are selected.
  • soft-touch surfaces and / or foam skin surface material Preferably soft-touch surfaces and / or foam skin surface material.
  • the deck area of the handle must meet the safety requirements. In particular, consider the flame retardancy and fire protection properties and the slip characteristics of the material. If the material is too slippery, then there is little support in the sloping part of the escalator.
  • the handle strip cover layer is preferably formed of another plastic whose roughness is in a range of 0.4 to 8 microns, preferably 2 microns and / or its specific thermal conductivity ⁇ in a range of 0.05 to 0.5 W / mK, preferably 0.2 to 0.3 W / mK.
  • plastics such as: PA (polyamide), PA6 (Perlon®), POM (polyoxymethylene, eg Delrin®), PEEK (polyether ether ketone), PAS (polyarylene sulfide), PE (polyethene), PUR (polyurethane), PP (polypropene), PVDF (polyvinylidene fluoride), PTFE (polytetrafluoroethylene); Natural fibers or fiber composites or GRP (glass fiber reinforced plastic) or CFRP (carbon fiber reinforced plastic) or compression cement or fiber matrix or Polytron or prepregs (preimpregnated fibers) or injection ceramics or hemp cement or recycled material or combinations of the enumerated materials.

  • a gripping strip according to the invention whether consisting of only one material or of a material compound, of refractory or "self-extinguishing" materials.
  • PAS-PVDF from Faigle from Hard / Austria or, in particular, a plastic called Wytex® from Monahan Filaments from Middlebury, Vermont, USA, are suitable.
  • the International Patent Publication WO-A2-2006 / 010181 discloses an improvement in the fire resistance of a handle bar of a handrail for an escalator or a moving walkway by the application of a coating on the handle bar, and not the preparation of the handle bar itself from a refractory or self-extinguishing material. Which materials or materials give an improved fire-resistant coating is not disclosed.
  • the cross-sectional profile of a handle strip according to the invention can be shaped ergonomically improved, for example by curvatures and recesses better adapt to a resting palm and, for example, the enclosing thumb.
  • a preferred embodiment provides to provide an improved gripping opportunity for children by a diameter smaller and better integrated from below deeper bar in the handle bar.
  • the surface of the handle bar can be rough, smooth, fluted or knurled. Further, it may be coated, painted or colored, or as a physical vapor deposition (PVD) surface, as a metallized (eg, chromium vapor-deposited) surface, or as a DLC (Diamondlike Carbon) Protective layer of carbon) or plasma or nano-surface configured.

  • a passenger conveyor according to the invention has a handrail circulation, which is connected to the balustrade upper side by the form-fitting Intermeshing is guided by mutually complementary guide surfaces, but at the bottom of the balustrade, the handrail is supported with rollers. At least one of these rollers is designed as a track roller.
  • the handrail can be driven by one or more wheels.
  • a friction wheel is particularly preferred when the traction device is cast into the handrail strip and thus serves only as a reinforcement, or it is a design variant of a handrail without separate traction means.
  • track rollers or rollers but other returns are conceivable, and not only, as just described, on the balustrade bottom itself, but in a base area of the balustrade or below, sunk in the area of the structure or truss of the escalator or moving walk ,
  • the guidance of the handrail / grip strip on the balustrade upper side is formed in a form-fitting manner by interlocking and complementary guide surfaces on the balustrade top side and on the grip strips.
  • This means that the balustrade top is formed even in a minimal version as a rectangle having three guide surfaces.
  • the then correspondingly only three complementary guide surfaces of the handle surround the balustrade so that the handle bar comes to rest on the upper surface of the balustrade and give the lateral surfaces a lateral guide support.
  • an inventive handrail guide provides that the handle bar by means of a force application (against the wheel flanges of the track roller or roller) can not be moved laterally.
  • further guide surfaces are provided, which mesh like a tongue-and-groove connection.
  • a handrail guide which has only on the side surfaces of the balustrade - also vertically supporting - guide surfaces.
  • This embodiment variant has the particular advantage that a gap can be left between the handle bar bottom and the balustrade top, so that the rotational speed of the handrail can not be reduced, for example, if a person is firmly supported or a heavy piece of luggagerochrome.
  • a further preferred embodiment variant of a handrail guide according to the invention provides for preventing speed reductions due to increased friction values - small rollers or needle roller bearings or needle roller flat belts or cylindrical roller flat belts in the guide surfaces.
