Definitions

  • the invention relates to an escalator or moving walk, according to the preamble of claim 1.
  • Escalators and moving walks have become known, at one Escalator the speed of the step belt in the middle part increase in order to increase the conveying capacity. This solution however, only causes the Escalator in the middle part of a smaller number of people stands or goes.
  • the throughput of the escalator is determined by the Accessibility of the entry and exit area determined, and of course the nominal speed of the escalator. In Tests carried out in this connection have shown that the speed for safety reasons a predetermined Dimension should not exceed. These attempts have become norms performed the maximum speed of a step belt specify exactly.
  • Escalators regularly consist of horizontal entry and Exit areas and an extending between them sloping middle section. Between the middle section and the Entry and exit areas are each transition arches intended. Such transitions are basically disadvantageous because they increase the length of the escalator without promote their utility. However, they are required to the multiple acceleration caused by the drive chain of the Step band introduced to the passengers over the steps will limit. The passenger is in the transition arch between entrance area and middle section in vertical Accelerated direction and slowed down in the horizontal direction. It is also in the transition between the middle section and Exit area braked in vertical direction and in accelerated in the horizontal direction. This multiple acceleration is not only perceived as disturbing, but poses also an essential point of view that prevents that the escalator's rated speed continues to increase especially with a horizontal speed change not necessarily counting.
  • the invention is therefore based on the object of an escalator or a moving walk according to the preamble of claim 1 to create an increase in comfort for passengers enabled despite at least the same throughput, whereby nevertheless the overall length of the escalator or moving walk is shortened.
  • one can be achieved with the solution according to the invention Provide escalator or moving walk, the one without horizontal acceleration of passengers gets along.
  • the multiple acceleration of the transition arches is reduced in a single acceleration, which the passengers anyway with the Expect the beginning and end of the sloping middle section.
  • the Security but also the feeling of security becomes clear elevated.
  • the length of the escalator is reduced, after the transition arches can be omitted.
  • the carriers according to the invention allow a release and thereby shifting the step belt while the Drive chain as a revolving chain with one upper and one lower run between a pulley and a Drive wheel is tensioned, kept simple and only under the Middle part is provided.
  • this Solution automatically results in an acceleration in the middle part, namely by cos ⁇ if the escalator angle is ⁇ .
  • this acceleration does not lead to a horizontal one Acceleration; the horizontal speed remains rather constant, whereby the carriers ensure that that the distance between the steps in the Vertical projection onto the floor remains the same.
  • a escalator according to the invention a drive with less Effort requires after the drive chain only in the middle part circulates and loaded bypasses for the drive chain can be omitted.
  • the wear for the drive chain is lower after the limb movements become clear for example by about half, so that the Maintenance intervals can therefore be extended.
  • the principle underlying the invention also for moving walks deploy. This is particularly convenient if long Moving walks are used.
  • the middle part of such escalators is then appropriately inflated according to the invention. hereby
  • the moving walk user saves the effort, the moving walk completely sink.
  • transition areas provided that the level increase without loss of speed enable, in the inventive manner no horizontal acceleration is initiated.
  • the only solution then is the horizontal middle part of a main drive chain driven, and it is convenient short additional drive chains in the transition areas provided the transition area, also called a Kind of short middle section can be seen, drive.
  • the Invention is provided in the middle part of the escalator to use several drives. Due to the straight structure of the In the middle there is no one over the course changing, therefore constant speed. This makes it possible to combine several drives that over appropriate chains drive the step belts. Optional every drive with the appropriate chain can do this be short, or a common chain length can be used be, so that theoretically an almost unlimited amount of funding is achievable.
  • the escalator 10 shown in Fig. 1 has a central part 12 and an entry area and an exit area that extend horizontally. It goes without saying that Entry and exit area depending on the direction of travel Change escalator. For the sake of simplicity, here is that lower horizontal area as entry area 14 and the upper horizontal exit area as exit area 16 designated.
  • the drive is the Escalator provided above.
  • the drive motor of the escalator is accordingly adjacent to the exit area 16. He drives a drive sprocket 18 that drives a drive chain 20 leads and redirects.
  • the drive chain is between the Drive sprocket 18 and a deflection arc 22 out.
  • the Deflection bend 22 is resilient in a manner known per se preloaded to keep the drive chain 20 in tension. It goes without saying that instead of the deflection bend 22 in one modified embodiment also a deflection wheel can be provided.
  • the drive chain 20 has an upper chain center 24 and lower chain center 26. Both chain strands extend straight between deflection bend 22 and drive sprocket 18, see above that the only redirections of the chain at the beginning and end dreams 24 and 26 take place. In contrast to the previous ones well-known escalators is accordingly the entry area 14 and the exit area 16 free of a drive chain 20th
  • the drive chain 20 has a plurality of drivers 28, which with drive chain 20 and a plurality of stages 30th drive, which form a step belt 32, which is only partially is shown.
  • the drivers 28 are designed in a suitable manner, so that they act in both directions, so the escalator can also work in two-way operation. additionally they have lead-in chamfers, which a possible game at the Approach of the pushed step to the driving driver to facilitate the intervention.
  • stage 30 spacing design selected from each other so that they are in the horizontal area have a certain gap, that of a mutual Gearing is bridged in a manner known per se.
  • FIG. 2 A modified embodiment of the solution according to the invention can be seen from Fig. 2.
  • a moving walk there shown, which is inflated in the central part 12 and itself for example, can extend above a floor 40.
  • This Solution allows no sinking of the middle part 12 To make moving walks. Accordingly, moving walks can also be installed in buildings that do not have a particular floor thickness have after only the entry and Exit area 14 and 16 must be lowered.
  • the Middle part 12 is upstream and between middle part 12 and entry area 14 extends. It is understood that a corresponding additional middle part 42 also on the exit side is provided.
  • the additional middle section has an additional one Drive chain 44 on the same scheme as that Drive chain has 20 drivers and the moving walk pallets 30 pushes in the entry area 14.
  • FIG. 3 shows the manner in which the stages according to the invention can be connected to each other to ensure the desired leadership.
  • Each stage points to its rear end of a connecting claw 50, which over a Guide pin 52 engages in an elongated hole 54, which extends vertically, that is perpendicular to the tread of step 30.
  • the combination of connecting claw 50, guide pin 52 and slot 54 forms a driver 28 of the steps together.
