Definitions

  • the invention relates to a step element for moving walk or stairs, with a step plate for receiving the people to be transported, this step plate being provided with an edge strip attached to it in the area of at least one of its longitudinal edges.
  • tread elements with edge strips, either their attachment by means of a few screws to the tread element, seen over a longer period of use, which is sometimes not able to cope with the extremely harsh operating conditions and / or relatively complex mechanical processing of the tread elements produced in the die-casting process are required .
  • the object of the present invention is to provide a step element which does not have the disadvantages mentioned above and is extremely simple to assemble and simple Way allows a good fixation of the sidebar over its entire length.
  • the tread element including the grooves intended for receiving the edge strip springs and provided in the tread plate, is produced by the die-casting process, and that the direction of insertion of these grooves and preferably the longitudinal axis of the locking bolts and the associated passage openings in the tread plate runs parallel to the direction of extension of the tread element from the die casting mold during its manufacture. It is expedient if the direction of insertion of the grooves and tongues is at an angle of 25 to 50 °, preferably 38 °, with respect to a perpendicular to the step plate plane.
  • the present invention also relates to an edge strip for a tread element according to one of claims 1 to 16.
  • the tread element 1 (hereinafter called escalator step) of an escalator is provided with a tread plate 2 for receiving the person to be transported.
  • the tread plate 2 has edge strips 3, 4 and 5 inserted into it and fastened to it.
  • the rear edge strip 3 has a spring 6 and 7 on its underside along its two longitudinal edges, the cross sections of which have the shape of a parallelogram with angles identical to one another, and in the manner of a Engage the tongue and groove connection in the corresponding grooves 8 and 9 in the tread plate 2.
  • This rear edge strip 3 furthermore has on its underside two guide and locking bolts 10, which are distributed over its length, downwards and through and through the adjoining tread plate 2, which form a piece with the edge strip 3, and at the edge of which Step plate 2 protruding downward free ends each a clamping ring 11 which is supported under spring pressure on the underside of the step plate 2 is clamped.
  • the tread element 1, including the grooves 8 and 9 provided in the tread plate 2 for receiving the edge strip springs 6 and 7, is produced by the die-casting process, the direction of insertion of these springs 6, 7 and grooves 8, 9 and the longitudinal axis of the guide and locking bolts 10 and the associated guide and passage openings 12 in the tread plate 2 run parallel to the extension direction Z of the tread element 1 from the die casting mold during its manufacture, so that the simplest possible die casting die can be produced.
  • this extension direction Z runs at an angle ⁇ of 38 ° with respect to a perpendicular to the step plate plane 13.
  • the edge strip 3 is provided with the same rib division as the tread plate 2, with mutual locking the ribs 14 of the edge strip 3 with the ribs 15 of the tread plate 2, part of the ribs 14 of the edge strip 3 are provided on their sides adjacent to the ribs 15 of the tread plate 2 with guide grooves 16, into each of which a front-arranged guide ridge 17 of the adjacent ribs of the Step plate 2 engages.
  • the guide combs 17 are open on their lower end faces 18.
  • the two lateral edge strips 4 and 5 are provided on their underside with a plurality of springs 19 which are distributed over their length and extend in their transverse direction, the cross sections of which are analogous to the springs 6 and 7 of the rear edge strip 3 have the shape of a parallelogram with mutually identical angles and engage in corresponding grooves 20 in the step plate 2 in the manner of a tongue and groove connection.
  • the guide and locking bolts 10, the guide and passage openings 12 assigned to them and the tongue and groove connections 19, 20 are coordinated with one another analogously to the rear edge strip 3 in such a way that they unimpeded retraction of the springs 19 of the two edge strips 4 and 5 in allow the grooves 20 associated with these springs 19 in the tread plate 2.
  • the insertion direction Z of the tongue and groove connection 19, 20 and the guide and locking bolt 10 is the same as for the rear edge strip 3 already described above for the simplest possible production.
  • edge strips 3, 4 and 5 are extremely simple, since they are simply inserted obliquely into the tread plate 2 and then the clamping rings 11 onto the free ends of the guide and locking bolts inserted into the tread plate 2 that protrude from the underside of the tread plate 2 10 can be pressed.
  • the clamping rings 11 are made of spring steel and are shaped so that they can be pressed onto the slightly conical locking bolts 10 in a simple manner up to the resilient contact on the underside of the tread plate 2 and then there automatically on the latter clamp. Slightly cambered spring washers or disc springs as well as so-called Schnorr rib washers can also be used as clamping rings 11.
  • edge strip 3, 4 or 5 In order to be able to easily replace such an attached edge strip 3, 4 or 5 in the event of any damage during operation, e.g. 11 can be seen in the longitudinal axis of the guide and locking bolts 10 on the top of the edge strips 3, 4 and 5 and on the downward free end face of the guide and locking bolts 10 centering countersinks 22 and 23 for centering a drill for drilling out the relevant guide - And locking bolt 10 are provided so that the latter can be eliminated in a simple manner and the defective edge strips can be removed without the subsequent attachment of a new edge strip causing any additional problems.
  • the grooves 19 'and the springs 20' are provided with a dovetail cross section.
  • edge strips 4 ', 5' can be pushed into each other because of the shape of the grooves 19 'and the springs 19' only in the lateral direction of these edge strips 4 ', 5'.
  • the two lateral edge strips 4 and 5 on their longitudinal edge, which is directed outward with respect to the tread plate 2, with a first side skirt that extends downward and forms a piece with the edge strip 4 and 5, respectively 26, and the arch-shaped front wall 27 (see FIG. 14) of the step element 1 with two lateral side skirts 28 which extend from the front wall 27 to the rear.
  • the common dividing line 29 between the partially abutting respective two side skirts 26 and 28 runs at the same or a larger angle ⁇ than the insertion direction Z of the tongue and groove connection 19, 20.
  • the side skirts 26 of the edge strips 5 ⁇ or 4 ⁇ (not shown) are provided with a guide groove 16 ⁇ in their area adjacent to the associated side skirt 28, into which a guide comb 17 ⁇ of the associated side skirt 28 is provided for mutual lateral fixing and centering of the tread element 1 engages.
  • the escalator steps consist of a magnesium alloy and the edge strips 3, 4 and 5 together with the locking bolts 10 provided on them from weatherproof, impact-resistant and aging-resistant plastic.
