Definitions

  • the invention relates to a safety device for lifting the gap between the tread and the front part of a moving step and a stationary base plate of an escalator arranged on both sides along the step band that can be entered, an insert piece that can be screwed onto the side edges of the step one between the tread and the front part the step and the base plate arranged plastic lip, which rests under external load, sliding against the base plate and covers the gap between the step and the base plate.
  • Such a safety device which has become known from US Pat. No. 4,519,490, has plastic parts which are clamped on the outermost or on the second lateral rib of the treads of the steps and cover the clearance between each step and the base plate with a protruding flap sliding on the base plate and / or close completely with a side insert. It is a plastic with a low coefficient of friction compared to the base plates.
  • the plastic parts clamped onto the ribs of the tread plates additionally require a relatively large lateral play in the upper and lower horizontal running area of the step belt when the steps pass through the combs.
  • a disadvantage of this device is that the clamped plastic parts in the direction of travel of the steps can be moved or even torn out of the clamped bracket. In addition to the increased lateral clearance with an increased risk of pinching when there is no or displaced plastic part, there is then the increased risk of pinching in the area of the entry of the step into the comb due to the increased lateral clearance.
  • a disadvantage of this design is that the outermost rib must be of the same hardness as the other, accessible ribs of the screw-on plastic part, and that a wedge-shaped longitudinal groove is necessary so that the outermost rib becomes so flexible that it only requires effort slides against the rib on the base plate.
  • the wedge-shaped longitudinal groove can also fill with dirt over time, whereby the effectiveness of the flexible outermost rib is partially lost. If the slide lip wears, the entire screw-on plastic part must be replaced.
  • the present invention is based on the object of proposing a protective device arranged on both sides of the step, which is firmly and immovably connected to the step, has a plastic lip which always closes the gap between the step edge and the base plate and which can be replaced individually when worn and in the area of the step entry into the comb does not require a substantial increase in the entry clearance.
  • Another advantage is that the plastic lip always closes off the clearance between the step edge and the base plate and the plastic lip only slightly projects beyond the outermost rib on the side, so that the clearance for the passage of the step through the one at the top and the bottom of the accessible area Conveyor line arranged comb, in the area of the left and right base plate, only need to be enlarged very little.
  • 1 denotes the step of an escalator.
  • the step consists of a step surface 1.1 and a front part 1.2.
  • straight plastic inserts 2; 3 and in the area of the front part 1.2 arched plastic inserts 4; 5 fastened in corresponding recesses of level 1 by screws 11.
  • a plastic connecting insert 13 is screwed onto the rear edge of the step surface 1.1 in a corresponding recess on the body of step 1.
  • the straight and the curved plastic inserts 2; 3; 4; 5 have corresponding elastic plastic lips 6; 7; 8th; 9, which slide against the base plates 10 arranged on both sides of the endless step belt which can be entered.
  • plastic lip 7 is part of a plastic piece 15 screwed together with the insert 3.
  • a comb 12 which is arranged in the upper and in the lower entry area of the escalator, where the endless step belt disappears under a step plate depending on the direction of travel or emerges from it.
  • the slightly increased lateral margin for the passage of the plastic lip through the comb 12 is designated 12.1.
  • the plastic lip 7 shown in section in FIG. 2, for the area of the treads 1.1 of stage 1, is also basically the same in the area of the end parts 1.2.
  • These plastic lips 8; 9 are adapted accordingly to the arched inserts 4; 5 and also arched.
  • the safety device described above is installed in escalators with an endlessly extending step belt in a supporting body.
  • the endless revolving step belt has a larger number of steps 1, preferably in die-cast aluminum, which are articulated on both sides with an endless step chain.
  • the step belt is deflected via upper drive sprockets and lower deflecting sprockets and has a walkable advance with a lower and an upper horizontal and an inclined running area and a return arranged concealed in the supporting body.
  • the lead of the step belt is arranged between two side handrail balustrades and is guided past fixed base plates 10 on both sides with minimal play.
  • the plastic lip 6; 7; 8th; 9 is on the inserts 2; 3; 4; 5 attached so that they do not have any of the outer ribs of the insert pieces 2; 3; 4; 5 encompasses and the outer rib projects only minimally beyond the side, so that only a minimally increased lateral clearance 12.1 is required for the passage of stage 1 by a comb 12 arranged during the transition from the accessible feed to the covered return of the step belt.
  • the plastic lip 6; 7; 8th; 9 can at any time together with the insert 2; 3; 4; 5 can be screwed or unscrewed from step 1 without having to remove step 1 from the step belt itself.
  • the invention is not limited to the illustrated embodiment. It is within the scope of the invention, for example, to equip escalators with base-less balustrades with the safety device, the plastic lips instead of on base plates directly sliding against vertically arranged balustrade panels and thus covering the gap between the step and the balustrade panels.
