Definitions

  • Escalators and moving walks are increasingly using plastic steps or pallets.
  • plastic steps or pallets are comparatively light in weight on, their strength by adding a Glass fiber proportion in relation to weight be particularly good can.
  • Plastic pallets are therefore fundamentally suitable especially for long moving walks, such as at airports and plastic steps for escalators particularly large delivery heights.
  • a plastic stage According to the preamble of claim 1, e.g. known from US-A-5 358 089.
  • Step suspension usually via a mounting eye penetrating hollow axis takes place, the mounting eye clamped via a nut on the hollow axle could loosen up by crawling the material.
  • the invention has for its object a plastic stage for escalators and / or a pallet for moving walks according to the preamble of claim 1 to create the has improved durability, the cost advantages of Maintains plastic levels compared to metallic levels and nonetheless, there is a risk of accident when using Excludes plastic steps.
  • the fastening eye embedded pressure elements the fastening eye is relieved of pressure itself.
  • the continuous load is periodic changing alternating load transferred.
  • Plastic has regularly though no problems withstand alternating loads, especially these are significantly less than the pressure load on the between Clamping elements clamped fastening screws from Plastic escalator steps.
  • the alternating load results practically automatically from the fact that the escalator step when circulating on that of the drive chain worn hollow axle rests when the step is on the upper run located while hanging on the hollow axis when the one under consideration Step is in the area of the lower run.
  • Steel pins or the like are preferred as pressure elements used between the two sides of the Extend eye and thus the initiated tension or Take up the compressive forces of the clamping elements for the fastening eye.
  • the steel pins can be made entirely of plastic be surrounded, the end faces of the pins can also exposed. The contact surface of the plastic on the Steel pins are therefore comparatively large.
  • the production of such a fastening eye according to the invention either so that appropriate holes are drilled at the points where the steel pins extend and that these are then driven in at these points be, or such that the steel pins in the injection mold introduced for the plastic stage and then molded become.
  • the anchoring is in the latter alternative better, which is only possible if the shape division the injection mold is provided at a suitable location.
  • any other suitable printing elements are also used can be.
  • an embedded partial annulus which extends across the eye, too can be used well as a pressure element.
  • the pressure elements are preferred designed metallic, according to a modified Design ceramic pressure elements provided are. Ceramic is particularly pressure-resistant but not very elastic, which, however, is not a problem for this application.
  • the configuration of the tensioning elements can also vary widely Areas to be adapted to the requirements.
  • Prefers forms a shoulder on the hollow axis a clamping element, and the tension is exerted by a tension nut via pressure-resistant holding elements evenly distributed on the dowel pins.
  • the Use of nuts, which may also be unsecured is not critical here, because of the extremely firm and rigid connection between the contact shoulder, the dowel pins, the counter-holding elements and the clamping nut is a Working of the storage generated in this way practically impossible.
  • the plastic step 10 shown in Fig. 1 has in itself known manner on a tread 12 and a riser 14.
  • the tread 12 is on the opposite of the riser Side of a support profile not visible in detail supported.
  • With regard to the detailed structure of the plastic stage be the full content of the parallel German patent application P 197 22 819.4.
  • the plastic stage 10 is guided in a manner known per se Way over a four-point hitch.
  • the plastic step 10 has a receptacle 18 for a guide pin 16.
  • the guide pin 16 supports one Towing roller, not shown, on which the plastic stage 10 is performed.
  • FIG. 2 Hollow axis 22 can be seen.
  • the hollow axis 22 serves the transmission of the driving force of a not shown Drive chain that runs on both sides of plastic level 10, to this.
  • the use of a hollow axis 22 enables one good rigidity in relation to the material used, so that the Tread surface 12 via a corresponding profile on the hollow axis can be supported.
  • the hollow axis 22 is from a bearing axis or a bearing pin step through, or the leadership roles for the Plastic steps 10 and each with the drive chain connected is.
  • the fastening eye 20 is for receiving the hollow axis 22 formed essentially U-shaped, the U-shape of a Mushroom shape is approximated.
  • An insertion slot 24 is accordingly somewhat tapered so that the round one there is preferred Hollow axis 22 using the spring properties of the Plastic stage 10 can be pressed into the fastening eye 20.
  • the fastening eye 20 has pressure elements 26 on, which are preferably designed as steel pins. she extend across the mounting eye 20 and are adjacent to the inner edge of the mounting eye 20, however completely encased in plastic material. The location and Arrangement of the pressure elements 26 in the clamping edge of the Attachment eye 20 can be seen well from Fig. 1.
  • clamping elements 30 on the hollow axis 22 provided with the pressure elements 26 of the mounting eye (20) interact.
  • the clamping elements 30 have a Axis shoulder 32 on the hollow axis 22 on the outside points and their radial extension up to the pressure elements 26 is enough.
  • the tensioning elements are on the opposite outside 30 a pressure profile 34, the fastening eye 20 on one side overlaps and in this respect at the same time as an anti-rotation device acts, as well as a clamping nut 36 with a washer 38 acts on the pressure profile 34.
  • the hollow axis 22 has a taper at its outer end on which an external thread 40 is applied, which for Internal thread of the clamping nut 36 fits.
  • a plurality of pressure elements 26 are provided, whereby from Fig. 1 five evenly around the circumference of the mounting eye 20 distributed steel pins can be seen. It understands yourself that the number of steel pins, but also theirs Design in a wide range of requirements is customizable; instead of steel pins 28 can also any other, intimately anchored with the mounting eye 20 Pressure elements 26 are used.
  • the clamping nut 36 as unsecured clamping nut is screwed on, it goes without saying that a known screw lock is used if necessary can be.
  • the taper the hollow axis 22 at its outer end and the length of the External thread 40 is selected so that the required Voltage can be applied to the pressure elements 26. If necessary, the length of the taper can also be so be chosen so that they have a stop for screwing forms, which is set so that the clamping nut 36 is not can be tightened so much that the mounting eye 20 too Damage comes.
  • Fig. 3 is a possible embodiment of the front Bolt clamping of a plastic step according to the invention shown.
  • the guide pin 16 is in the receptacle 18 of the Plastic level 10 added.
  • a socket 42 With plastic level 10 anchored is a socket 42, be it by pressing in, by Glue in or by injection.
  • Guide pin 16 With its clamping nut 36, the bushing is designed as a pressure element, and between the clamping nut 36 and bolt head 44 generated pressure via a washer 46 is introduced into the socket serving as a pressure element.
