Definitions

  • the invention relates to a step of an escalator with a step surface, an end face and two each with a drag roller and a fastening device for connection to an endless means of transport provided side plates, a step belt consisting of a plurality of steps and two endless means of transport between two fixed base plates is guided and wherein between the body of the step and the base plate two segments are movably mounted on the side plate of the step and can be brought into a predetermined position relative to the step surface of the step.
  • the resulting friction against the direction of travel is then dependent on the direction of travel of the escalator at the upper or at the lower transition point, where the step heels decrease or form, a relative movement with friction transverse to the direction of travel, through which mainly light footwear can be drawn between the moving step and the fixed base plate.
  • a step for escalators with such a protective device has become known from European Patent 0 087 692.
  • two-part side walls are provided, which can be pivoted apart in a fan-like manner about a common pivot point arranged above the drag roller on the side plate.
  • the two side wall parts lie against the step body and rest together side by side on the axis connecting the step with the means of transport.
  • the one side wall part carried along by the neighboring, leading step first rises and then in turn takes the second side wall part with it in a fan-shaped manner in order to cover the distance between the tread plate of one and the other Completely cover the front part of the leading step in the area of the sloping track against the base plate.
  • the relative movement that previously took place between the moving step and the fixed base plate is thereby converted into a relative movement between the moving step and the side wall moving at the same speed, which greatly reduces the risk of lateral pulling in, but is not completely impossible.
  • a further step for escalators with a protective device mentioned above is disclosed in German Patent No. 2 161 442.
  • the lateral edge strips and the edge strip of the step plate directed towards the front part of the adjacent step are formed with differently colored insert pieces.
  • the side inserts can also exceed the step height of the rest of the step plate.
  • the colored edge strips have the task of visually marking those places on the step plate that should not be entered.
  • the possibly raised side inserts should also result in an uncomfortable foot position for the passenger when entering and prompt him to put his foot away from this area.
  • a disadvantage of this invention lies in the fact that the colored edge areas are not observed or are not visible at all when there is a high frequency of people, and the side edge raised edge area of the tread plate is not so for structural reasons (greater space requirement in the area of the upper and lower reversal points covered by the tread plates) high that the passenger has a really uncomfortable foot position when entering.
  • the invention has for its object to propose a step for an escalator, by means of which the passenger is warned by an acoustic and / or physically perceptible signal when entering the danger zone of the step plate.
  • the advantages achieved by the invention are essentially to be seen in the fact that the passenger, when entering the lateral danger zone of the step surface of the step, or when pressing a foot into a corner formed by the step surface of the step, the base plate and the end face of the adjacent step , is warned by the vibrating step. Depending on the design of the lower edge of the base plate and the transfer medium In addition to vibrating, an acoustic signal generated by rattling can also be heard.
  • a further advantage lies in the fact that the step according to the invention manages with the previously available space area and does not require serious changes in the comb plate area, as is the case with the steps with a greatly increased side area.
  • a drag roller 2 is rotatably mounted on a side plate 1.1 of stage 1, which has a grooved tread 1.2 and a grooved end face 1.3.
  • a pivot pin 5 for the pivotable mounting of a first segment 3 and a pivot pin 6 for the pivotable mounting of a second segment 4 are arranged on the same side plate 1.1.
  • the first segment 3 has a grooved tread 3.1 and a grooved end face 3.2.
  • the second segment 4 has a grooved tread surface 4.1.
  • the two segments 3, 4 are connected to one another by a pin 7 arranged on the first segment 3, which engages in a guide slot 8 arranged on the second segment 4, and are pressed apart into a ready position by a common spring 10.
  • a pin 9 provided at the most distant point of the first segment 3 works together with a profiled guide edge 11.1 of the base plate 11.
  • a loading force acting on the tread surface 3.1.4.1 is designated by 20, a loading force acting on the end face 3.2 is designated by 21.
  • a force pressing the pin 9 against the profiled guide edge 11.1 of the base plate 11 is designated by 22.
  • An arrow 23 indicates the direction of the pivoting movement of the segments 3, 4 occurring at least in one of the loads 20, 21 mentioned above.
  • the lower edge of the base plate 11 is equipped with a wavy guide edge 11.2.
  • the transmission means engaging in the wavy guide edge 11.2 is a rotatably mounted roller 12.
  • the drag roller 2 is rotatably mounted on the side plate 1.1 of stage 1, which has a grooved tread 1.2 and a grooved end face 1.3.
  • a pin 15 for the pivotable mounting of a first segment 13 is arranged on the same side plate 1.1.
  • a support point 13.3 is provided on the upper edge of the first segment 13, on which a second segment 14 guided in parallel in vertically arranged guide slots 16 is supported.
  • the first segment 13 has a grooved face 13.2, while the second segment 14 has a grooved tread 14.1 and a grooved face 14.2.
  • the common compression spring 10 inevitably distances the two segments 13, 14 and holds them in a standby position at least partially protruding from the tread surface and the front surface of the step.
  • the most distant point of the segment 13 arranged pin 9 engages in the profiled guide edge 11.1 of the base plate 11 when the tread or end faces are flush.
  • the loading force acting on the grooved tread surface 14.1 is designated by 20, the loading force acting on the end face 13.2 by 21.
  • the force pressing the pin 9 against the profiled guide edge 11.1 of the base plate 11 is again designated 22.
  • the arrow 23 indicates the direction of the pivoting movement of the segment 13 which occurs at at least one of the loads 20, 21 acting on the segments 13 or 14.
  • the devices described above work as follows:
  • the segments 3, 4, 13, 14 which are arranged to the side next to the side plate 1.1 of the step 1 are pivoted or pushed by the force of the compression spring 10 in the at least partially protruding from the step surface and the end face of the step Stand by position. If the passenger steps too close to the base plate on the grooved tread of the segments 3, 4, 14 and / or presses a foot into a corner formed by the base plate 11, the tread 1.2 and the end face 1.3 of the adjacent step 1, the segments become 3, 4, 13, 14 pressed into the flush position, in which at least the first segment 3, 13 executes a pivoting movement indicated in the direction of arrow 23.
  • the pin 9 is pressed with a force 22 corresponding to the load force 20, 21 against the profiled guide edge 11.1 of the base plate 11.
  • the two pivotably mounted segments 3, 4 are connected to one another by the pin 7 engaging in the guide slot 8.
  • the rotary movement according to arrow 23 that occurs when entering or actuating at least one of the two segments 3, 4 is thereby always transmitted to the first segment 3, which is thereby connected by the pin 9 to the profiled guide edge 11.1 of the base plate 11.
  • only the first segment 13 is pivotally mounted, while the second segment 14 is guided in parallel in vertically arranged guide slots 16.
  • the support point 13.3 arranged on the first segment 13 ensures that here as well, when the second segment 14 is entered or the first segment 13 is actuated, a rotary movement according to arrow 23 acts on the first segment 13, which is also caused by the pin 9 is brought into connection with the profiled guide edge 11.1 of the base plate 11.
  • the pin 9 slides over the profiled guide edge 11.1 of the base plate 11 and sets the step in vibration.
  • an acoustic signal generated by rattling can be added to the vibration of the step.
  • the escalator user is warned by a physically perceptible signal and possibly also by an acoustic signal to leave the entering danger area of the step and not to enter it again.
  • a rotatably mounted roller 12 could also be provided.
  • another spring for example a torsion spring, could achieve the same effect.
