Definitions

  • the invention relates to an escalator, which is guided in the manner of a spiral staircase, with a plurality of movable stair steps which are designed in the shape of a sector of a circle and run on at least one stationary, helical guide, a vertical center column which is arranged in the center of the stair area, a coupling device arranged in the circumferential area of the center column for holding and guiding the narrow inner side ends of the steps, and a drive for moving the steps, with which at least the coupling device of the center column can be driven in the direction of rotation about the vertical column axis.
  • the center column is rotatably mounted and provided with longitudinally extending guides with which the radially inner ends of the steps are constantly in clutch engagement.
  • a stationary guide is provided at a distance from it, on which the radially outer ends of the steps run.
  • the endless guide is circular and has a helically rising part and a helically falling part, that is to say that the guide is self-contained.
  • the invention has for its object to provide an escalator that can be accommodated in a confined space without losing any of the advantages of the known escalators.
  • this object is achieved in that the steps are connected to one another in an endless chain, in that only the wide, outer side ends of the steps are coupled with the respective adjacent side ends of the adjacent steps via connecting elements which pivot the steps relative to one another approximately vertical axis and also allow an approximately vertical displacement of the steps relative to one another, and that the steps are detachable from the coupling device with which the inner side ends of the steps are held.
  • the spiral escalator according to the invention can be carried out in a confined space over any height by running the stair steps around the respective central column as often as desired.
  • the spiral escalator according to the invention can be designed as a simple step up or as a simple step down. In this case, the empty run is guided through the correspondingly designed interior of the center column in a space-saving manner.
  • An upstairs staircase is preferably combined with a downstairs staircase, the staircase steps of both Stairs form the endless chain. Only one drive is required for both stairs, each with a separate center column.
  • the two center pillars of the up and down stairs are suitably arranged close together, so that the the chain formed by the individual steps can be kept relatively short.
  • Such a double staircase can be designed as a compact unit that can be attached to buildings as a tower on the outside. Subsequent installation of such a unit is easily possible.
  • Such tower-like units can also be easily guided over several floors.
  • spiral escalator according to the invention is particularly suitable for single-family houses, for road overpasses or underpasses, which are to be created in particular in the area of narrow sidewalks, on exhibition stands etc., in particular in view of their small space requirement and low price.
  • the spiral escalator can be adapted to any floor height.
  • the steps expediently have a box-shaped structure, so that on the one hand they are self-supporting and on the other hand they cover the vertical area between the steps in order to avoid a risk of pinching for the user.
  • the connecting elements provided on the wide side ends of the stair treads can each consist of a vertical guide pin provided on one stair step and a sliding claw arranged on the other stair step and encompassing the guide pin by more than 180 °. Such a connection offers both the possibility of a rotation and a vertical displacement of the steps relative to one another.
  • support rollers with about very wide stairs are preferred horizontal axes of rotation provided, which run on the stationary helical guide. With the help of these support rollers, the steps in the lifting area are kept horizontal.
  • additional guide rollers with approximately vertical axes can be provided on the outer, wide side ends of the steps, which rest on at least one side guide. These guide rollers are used in particular to guide the stairs in the plane.
  • further support rollers can be provided under the middle area of the steps, which rest on corresponding guideways at least in the acceleration and deceleration areas and in horizontal areas.
  • a comb toothing is expediently provided on the vertical step walls between adjacent stair steps, as a result of which the orientation of the steps is positively influenced relative to one another, as a result of which the safety against possible pinching is positively influenced.
  • an additional circular comb toothing can be provided on the treads of the steps.
  • extendable support bars are preferably provided for very wide stairs a little below the treads, on which the underside of the higher step is supported in the stair area during the upward or downward movement. This construction results in a stable staircase.
  • the coupling device which serves to hold and guide the inner side ends of the steps can be fastened to the central column, the central column being drivable and thereby simultaneously forming the drive for the spiral escalator.
  • the drive of the center column can attack at its upper or lower end.
  • the column coupling device can be formed by vertical guide rods or other corresponding guides which are arranged evenly around the circumference of the column at intervals of the steps, the steps having an open claw at their narrow side ends, which in the case of the upward stairs from below and can be threaded onto the associated guide rod or guide from the top of the down stairs.
  • the center column can also be arranged in a stationary manner and have a helical guide slot corresponding to the slope of the stairs, a rotatable drive spindle with worm threads or helical drive rails running counter to the guide slot being arranged in the interior of the center column.
  • a driver that extends through the guide slot and interacts with the respective worm gear or the respective drive rail can be arranged.
  • a hydraulically or pneumatically operating crawl lifting mechanism acting directly on the individual stages can also be used as the drive Foot of the center column may be provided.
  • the steps can be divided in two across their width, with only the outer parts of the steps in the entry and exit areas being provided with acceleration and deceleration sections with the aid of corresponding lifting curves.
  • People who want to be transported over several floors choose the inner staircase area, which carries out a continuous lifting movement between the individual floors.
  • To exit the stairs switch to the outer area of the stairs and leave it in its delay area.
  • the spiral escalator according to the invention can also be made at least partially in plastic, so that a variety of design and color options are available. Tubes or double tubes made of metal or plastic can be used as the outer boundary of the stairs. To attach the spiral escalator to an outer or inner facade, Plexiglas is suitable as the material for the outer tube, so that the user can look outside.
  • the right spindle is assigned to an upstairs step 5 and the left spindle to a downstairs step 6.
  • a common drive motor 7 is provided, which is installed below the level of the lower platform 4.
  • the spindles 2 consist of rotatable tubes 9, which are mounted on stationary guides and are driven by chain drives 8 by the common motor 7.
  • tread surface or the floor plan are approximately in the shape of a sector of a circle, although the tip is recessed with respect to the central tube 9.
  • a coupling device formed from round rods 12a serves as the inner holder and guide for the stair steps 13.
  • the round bars 12a which are arranged vertically, are fixed to the tube 9.
  • the inner side ends of the steps 13 have open ball bushings 12b which overlap the round bars 12a. In the entry areas, the ball bushings 12b are threaded onto the respective upper or lower ends of the round bars 12a and are separated from the round bars in the exit areas.
  • Radially arranged guide rollers 17 are provided on the outer, broad side ends of each step 13, which engage in corresponding guide grooves of the side walls or run on helical cam tracks. These horizontal guide rollers are used to keep the step horizontally.
