Definitions

  • the invention relates to a safety device for Passenger conveyors, especially for escalators and Moving walks with at least one comb plate, which a permissible level of excessive force in horizontal or vertical direction via corresponding Activated by a safety switch.
  • This regulation means that existing Security devices must be supplemented accordingly and that new designs of safety devices have already been carried out in accordance with regulations.
  • EP Application No. 0 621 226 describes and shows one Safety device by means of which the actuation of a Safety switch in horizontal and vertical directions is possible.
  • a permanently installed horizontally Release device with pressure spring, pressure pin and subsequent safety switch is made by one on rollers mounted comb plate for horizontal and vertical Comb plate movement actuated.
  • As an intermediate link between Comb plate and release device is a movable one Angle lever available. When the comb plate moves in in the horizontal direction, it is triggered without any co-function of the angle lever, although its vertical leg as Liner joins the movement. With a vertical Movement of the comb plate is the function of the angle lever in converting this vertical movement into a horizontal movement to implement.
  • the release paths are by means of set screws and the release force is by means of variable spring tension adjustable.
  • the ratio of the horizontal to the vertical The release force is due to the geometric dimensions alone or by the lever arm lengths of the vertical and given horizontal leg of the angle lever.
  • the front part of the Comb plate is somewhat flexible and can be used corresponding force in the vertical direction Actuate pressure generating hose.
  • the unchangeable fixed ratio of horizontal to vertical release force is perceived as restrictive.
  • the indirect transmission of the vertical comb plate movement for Tripping device via an angle lever is included additional friction connected and can, also as a result of Wear, the reproducibility of the release force in vertical, but also disadvantageous in the horizontal direction influence.
  • a Safety device for an escalator or one To create a moving walkway which does not have the disadvantages mentioned has and in particular an individual determination of allows horizontal and vertical release force.
  • the invention is characterized inter alia by in that the Ratio of horizontal to vertical release force without constructive intervention is changeable.
  • An adjustable position of the triggering force Spring is used to choose the ratio of horizontal to vertical release force.
  • the selected spring position is through a locking device secured.
  • the release force transmission from the comb plate to the Tripping device is immediate.
  • a shift lever 6 can also be pivoted on the axle pin 8 stored.
  • the shift lever 6 has one to the left one firmly connected to the support plate 2 Safety switch 10 extending leg on the end of which is bent slightly upwards as a switching curve is and with a downward movement the roller lever of the Safety switch 10 actuated.
  • Over the center of the Axle pin 8, the shift lever 6 has a short to the right continuing thighs that over at its end a driving pin 16 with an inclined surface of the Stop part 4 is connected.
  • the driving pin 16 has a compression spring 7, the one under the action of force Reduction of the distance between the short leg of the Switch lever 6 and the stop part 4 allows.
  • the main purpose of the spring 7 and the nut 22 is, however in the fact that when an external force is released a reset of the shift lever 6 in his Starting position can take place.
  • Stop screws 9 are on either side of the comb plate 1 arranged and limit their vertical path upwards Raised by vertical force.
  • the static force F can be divided into the horizontal component Fh and be broken down into the vertical component Fv.
  • In the set position of the axis of action of the spring 5 is Alpha angle approx. 60 ° to the horizontal.
  • Location of the spring 5 is in a graphical evaluation of the Force parallelogram shows that for an actuation of the safety switch 10 approximately in the horizontal direction Half of the force F, which corresponds to Fh, has to be overcome, and that for operating the safety switch 10 in vertical direction a much greater force, almost 90% of F, what corresponds to the force Fv has to be overcome.
  • the adjustment of the spring 5 in small angular steps on the Locking notches 12 allows any adjustment of the Ratio Fh: Fv.
  • the driving pin 16 also has Adjustment devices on. With the mother above the Stop part 4 becomes the starting position of the shift lever 6 adjusted by changing the length. With a second nut on the underside of the stop part 4 is a spring 7 biased.
  • the safety device is limited to constructive details not on the example shown.
  • the locking of the spring 5 in a certain position can also by means of fine perforation on the lower thrust washer 14 and on the circular arc-shaped edge of the leg 11 become.
  • Another adjustment construction would consist of the side of the two legs 11 each have an arcuate shape Except slot and the spring pin 15 by means of one Cross bolt with thread and nut continuously on any To fix the situation.
