- the measure according to the invention can also be advantageously implemented in the entire area of the escalator used by users/passengers, in particular along the entire route.
- the respective step roller axis is implemented as a force transmission means to counteract an undesirable upward vertical movement, in particular in that the respective step roller axis projects laterally beyond the respective step roller (unit).
- the respective step roller axis extends in such a way that the respective step roller axis projects beyond the corresponding step roller with a protruding axis section, i.e. protrudes from the corresponding step roller or other components provided for its storage, the height limiting device being at least partially between one/the stair step of the Stair step unit, in particular a stair step base body, and the step roller axis extends and thereby defines the height limit stop in relation to the step roller axis.
- This arrangement also delivers in terms of construction In terms of advantages, especially with regard to easy implementation of the height limitation measure.
- the respective step roller axis extends inwards, i.e. towards a central region of the respective stair step units, in such a way that the respective step roller axis projects inwards beyond the corresponding step roller and protrudes inwards from the corresponding step roller or other components provided for their storage, whereby the height limiting device extends at least partially between one of the steps of the stair step unit and the step roller axis and thereby defines the height limiting stop.
- This arrangement also enables particularly lean integration in a simple manner, for example into existing systems.
- the height limiting device has a section encompassing a free (in particular inner) end of the respective step roller axis, in particular a section which has an L-shaped cross-section and which encompasses the respective step roller axis, in particular with the encompassing section in (if the respective stair step unit is arranged as intended) Contactless arrangement relative to the respective step roller axis. Last but not least, this also enables location/position variations or adjustments for specific arrangements in a particularly simple and cost-effective manner.
- the height limiting device extends continuously along the displacement path at least in the region of one/the lead of the displacement path, in particular in that the height limiting device provides a guide rail section at least along the lead of the displacement path, in particular a guide rail section with an L-shaped cross section in an overlapping arrangement above the respective one Step roller axis.
- the height limiting device can be designed at least partially or in sections as an (additional) guide rail (or individual guide rail elements arranged in a row), which when used as intended (i.e. without vertical movement) are contactless relative to the Step rollers and stair step unit is stored or arranged. This also promotes application-specific implementation without significant additional effort.
- the height limiting device is connected at points or at least in sections to a rail for the step rollers, or to a support structure on which at least one guide rail for the step rollers is arranged.
- the height limiting device is arranged relative to the step roller axes (or the step roller axes are arranged and/or aligned in such a way) that the step roller axes come into contact with the height limiting device from a predefinable threshold value of 2mm or 3mm or 4mm of the upward vertical movement .
- the maximum permissible or maximum tolerated displacement tolerance in the height direction can also be specifically predefined, for example depending on a longitudinal position on the displacement path.
- the respective step roller axis is provided by means of a screw, in particular by means of a screw fixing the corresponding step roller.
- the respective stair step unit has at least one first step roller and at least one second step roller, in particular laterally on each side of the respective stair step unit, the first step roller being arranged in a front region (on the bow side in the direction of displacement) of the stair step unit, the second step roller is arranged in a rear (rear side in the direction of displacement) area of the stair step unit, the height limiting device being arranged in such a way that a/the Height limit stop is provided for an upward vertical movement of at least the step roller axis of the second (rear-side) step roller.
- the implementation at least on the rear step roller delivers a good effect with minimized technical effort in such escalators.
- a height limit can also be provided on the respective bow-side step roller.
- the aforementioned object is also achieved by using a height limiting device in an escalator device for limiting a vertical movement of a respective stair step unit of the escalator device, in particular in an escalator device previously described above, the height limiting device having a height limiting stop to avoid an upward vertical movement of at least one step roller of the respective Stair step unit is defined, in particular for the purpose of limiting any (undesirable, non-intended) vertical movement of the corresponding step roller to a maximum of 1mm to 4mm, by using the height limiting device to provide a surrounding section which encompasses a/the free end of a/the step roller axis of the respective step roller, in particular an encompassing section with an L-shaped cross section, in particular with an L-profile that is rotated by 180° compared to an L letter and is upside down.

- 2 shows a detailed view of the arrangement according to a preferred exemplary embodiment of the invention
- FIG. 3 shows a further schematic side view of the arrangement according to a preferred embodiment of the invention.
- An escalator device 10 comprises at least one escalator 11 with a plurality of stair step units 12, each of which is guided and supported on step rollers or step roller units 13, in particular laterally on both sides, for example with two step rollers (units) on each side of a respective stair step unit.
- the step rollers (units) 13 are guided over a rail or similar support structure (in particular guide rail) 14, in particular on one or two rails laterally on both sides.
- the present invention is now based on the concept of extending one/the axis XI 3 of the respective step roller (unit) laterally, in an arrangement laterally protruding from the step roller, so that a protruding axle section 13.1 is formed on the respective step roller, which has a free end 13.2.
- a height limiting device 15 with a height limiting stop 15.1 can be advantageously implemented in that a surrounding section 15.2 is/is guided around the free end 13.2 of the respective step roller axis X13.
- a guide rail section 15.3 with a comparatively large longitudinal extent (in the direction of displacement) can optionally be provided; individual brackets can also optionally be provided.
- a height difference Az is provided between the height limit stop 15.1 defined by the encompassing section 15.2 and the free end 13.2, namely between the intended height position of the step roller (axis) and the stop 15.1, the height difference Az depending on the design of the escalator and / or depending on desired movement tolerance in the height direction can be a few millimeters, for example 1mm to 3mm.
- an extended screw 13.5 can particularly advantageously fulfill the function of a protruding, extended step roller axis XI 3.
- the escalator device can also have the components known from the prior art for driving and controlling the displacement in the direction of travel, in particular a motor, a control unit, actuators, sensors, and the like (not explicitly described in the figures).
- Figure 1 shows an extended step roller axle X13 with a protruding section
- the protruding section 13.1 is separated from the surrounding one Section 15.2 of a height limit stop is included, so that a stop is provided in the upward direction of movement.
- a further step roller is also visible, which is arranged laterally offset and offset in the direction of travel to the step roller 13 described here (in particular in a front, bow-side area of the stair step unit).
- Figure 2 shows an axis XI 3 provided by a screw 13.5.
- the screw can be secured with a nut or nut 13.4, and a washer 13.3 can be provided to optimize the transmission of force.
- the axis XI 3 or the screw 13.5 sits in a base body of the respective step roller unit 13, on which a (ball/roller) bearing of the step roller can also be supported.
- the (undesirable) height movement of the step roller can be assigned a tolerance range by providing a height difference Az between the axis XI 3 and the stop 15.1, depending on the area of application.
- Fig. 2 The view shown in Fig. 2 is reversed to the view shown in Fig. 1.
- the implementation according to the invention can be provided on both sides of a respective stair step unit.
