Definitions

  • the invention relates to a step of an escalator in which a step belt consisting of a plurality of steps and two endless transport means is guided between two fixed base plates and the w steps have step edges protruding beyond the tread on their two outer sides.
  • both inventions have the disadvantage that the raised side parts of the step tread plates laterally require more space when passing through the upper and lower comb plates, and the risk of being pinched when entering a comb is significantly increased if a pinched plastic part becomes detached or out of any in the course of time Grounds on the step plate are missing.
  • the invention has for its object to propose a step for an escalator in which the risk of pinching between the steps and de, n base plates is reduced, which requires no additional space when passing through the comb plates and in which there is no additional risk of pinching when entering a comb can arise.
  • the advantages achieved by the invention are essentially to be seen in the fact that for each step in the area of the lateral danger zone, that is to say from the transition from the lower or from the upper horizontal path the inclined path and along the inclined path, between the step body and the base plate, at least one step plate rib movably mounted on the step body is raised and lowered again before entering the comb.
  • a shoe that is already sliding along the base plate in the area of the horizontal path is pushed up along the base plate, the frictional force on the base plate simultaneously decreasing. But it is more likely that the passenger will put their foot away from the danger zone as soon as they feel that they are being pushed up by the side edge.
  • a drag roller 2 is rotatably mounted on a side plate 1.1 of the step body 1.
  • a bearing journal 3 for the rotatable mounting of a rocker arm 4 is arranged on the same side plate 1.1.
  • One end of the rocker arm 4 has a guide slot 4.1 open on one side and the other end a closed guide slot 4.2.
  • a driver pin 5.1 arranged on a cam 5 engages in the open guide slot 4.1.
  • the cam 5 is direct or via a step axis 6 firmly connected to a hinge pin 7 of the traction element 8.
  • chain rollers 9 are rotatably supported, which support the step body 1 on guide rails 10.
  • a driver pin 11.1 arranged on the protruding tread edge 11 engages in the closed guide slot 4.2 of the rocker arm 4.
  • the protruding tread edge 11 is pressed down by the force of a spring 12 and is held outside a danger zone in a flush position with a tread surface 1.2 of the step body 1.
  • the spring 12 is supported on a support 1.3 arranged on the step body 1 and acts on a support 11.2 arranged on the protruding tread edge 11.
  • the protruding tread 11 is guided parallel to the tread 1.2 in a parallel guide 1.4 arranged perpendicular to the tread 1.2 on the step body 1.
  • 21 is another step body of an escalator.
  • a drag roller 22 is rotatably mounted on a side plate 21.1 of the step body 21 and horizontal sliding guides 21.5 and vertical sliding guides 21.4 are provided.
  • a link 24 is slidably guided in the horizontal slide guides 21.5, a protruding tread edge 23 in the vertical slide guides 21.4.
  • the link 24 has an open 24.1 and two closed guide slots 24.2.
  • a cam engages in the open guide slot 24.1 25 arranged driver pin 25.1.
  • the cam 25 is connected directly, or via a stepped axis, not shown, to a hinge pin 26 of a traction element 28.
  • Two driver pins 23.1 arranged on the protruding tread edge 23 engage in the closed guide slots 24.2 of the link 24.
  • the protruding tread edge 23 is pressed down by the force of a spring 29 and is held outside a danger zone in a flush position with a tread surface 21.2 of the step body 21.
  • the spring 29 is supported on a support 21.3 arranged on the step body 21 and acts on a support 23.2 provided on the protruding tread 23.
  • a chain roller 27 running on a guide rail 30 is rotatably mounted on the hinge pin 26 of the tension member 28 .
  • 31 denotes a further step body of an escalator, which has a side plate 31.1, a tread surface 31.2 and a pivot 31.3.
  • a protruding tread 38 is tiltably mounted on the pivot 31.3. Due to the force of a torsion spring 39 arranged on the protruding step edge 38, the protruding step edge 38 is held outside a danger zone in a flush position with respect to the step surface 31.2.
  • a bearing journal 33 is provided on the side plate 31.1, on which a rocker arm 34 is rotatably mounted. One end of the rocker arm 34 has an open guide tion slot 34.1 and the other end of a closed guide slot 34.2.
  • a driver pin 35.1 arranged on a cam 35 engages in the open guide slot 34.1.
  • the cam 35 is again connected directly or via a stepped axis, not shown, to a hinge pin 36 of a pulling element 40.
  • a chain roller 37 is rotatably mounted on the hinge pin 36 and supports the step body 31 together with a trailing roller 32 which is also rotatably arranged on the step body 31 on guide rails 41, 42, 43.
  • a driver pin 38.1 arranged on the protruding tread 38 engages.
  • 51 is the forward and 52 the return of a step belt 50.
  • the lead 51 extends between a lower comb plate 53 and an upper comb plate 54 and consists of a lower horizontal running area 55, a lower transition arch 56, an inclined running region 57, an upper transition arch 58 and an upper horizontal running region 59.
  • the step belt 50 turns into a lower reversal point 60 and in an upper reversal point 61.
  • the steps 1, 21, 31 always move with a horizontally running tread surface.
  • the hinge pins 7, 26, 36 of the traction element 8, 28, 40 are non-rotatably connected to the tabs of the traction element.
  • the cam 5, 25, 35 is connected directly or non-rotatably to the hinge pin 7, 26, 36 via the stepped axis 6.
  • the angle of attack of the cam 5, 25, 35 to the longitudinal axis of the traction element 8, 28, 40 is thus the same set.
  • the relative movement of the step body 1, 21, 31 with respect to the longitudinal axis of the traction element 8, 28, 40 which serves to form the step surface 1.2, 21.2, 31.2 of the step that always runs horizontally in the lead of the step band, also causes an angular displacement between the step body 1, 21, 31 and the cam 5, 25, 35.
  • This shift takes place in the area of the transition arches 56, 58 between the horizontal and the inclined step running up and down, it begins in the horizontal running area 55, 58 and reaches the largest in the oblique running area 57 Value.
  • the driver pin 5.1, 35.1 attached to the cam 5, 35 slides, according to FIGS. 1 and 4, in the open guide slot 4.1, 34.1 of the rocker arm 5, 34 arranged on the step body 1, 31, the rocker arm 5, 34 about the bearing pin 3, 33 rotates and tilts down on one side and upwards on the other side, and the protruding tread edge 11, 38 is inevitably moved upwards or downwards by the driver pin 11.1, 38.1 relative to the tread surface 1.2, 31.2 of the step body 1, 31.
  • each step emerges from the lower comb plate 53 with the tread edge drawn in flush with the tread surface and thus rolls over the lower horizontal running area 55.
  • the lateral tread edges also gradually rise until they pass into the oblique running area 57 at the top at the end of the lower transition arch 56.
  • the steps move along the inclined running area 57 and in the upper transition arch 58 the height of the protruding tread edges decreases again until the steps at the transition to the upper horizontal running area 59 and along the upper horizontal running area 59 with step edges placed flush with the tread surface run into the upper comb plate 54.
  • a link 24 shown in FIG. 3 can also be used. Due to the relative displacement of the cam 25 to the step body 21, the link 24 is moved back and forth, which in turn moves the protruding tread edge 23 up and down through the guide slots 24.2 and the driver pins 23.1.
  • an increasing inclined displacement of the protruding tread edge, as shown in FIG. 4, or a not inclined inclined displacement of the protruding tread edge can also be provided.
