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, with 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 above-mentioned disadvantages and is extremely simple to assemble and simple Way allows a good fixation of the edge 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 tread element 1 (hereinafter referred to as the 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 Tongue and groove connection engage in 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 and which extend downwards and through and through the adjacent tread plate 2, which form a piece with the edge strip 3 and at the end 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 intended for receiving the edge strip springs 6 and 7 and provided in the tread plate 2, 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 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 allow the springs 19 of the two edge strips 4 and 5 in to be retracted freely 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 which are inserted in the tread plate 2 and protrude from the underside of the tread plate 2 10 can be pressed.
- the clamping rings 11 are made of spring steel and have a cambered design, 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.
- the grooves 19 'and the springs 20' are provided with a dovetail cross section.
