Definitions
- Escalators and moving walkways have handrails arranged all around their balustrades, which move synchronously with the step belt of the escalator or the pallet belt of the moving walkway.
- These handrails are usually wire strand-reinforced profile belts made of elastomer material and are guided by handrail guide profiles, often also referred to as handrail guide rails.
- the handrail guide profiles are usually sheet metal profiles made of steel or stainless steel or extruded profiles made of polymer material or aluminum, which have an approximately hat-shaped cross section.
- the handrail guide profiles are not provided with a wear-reducing, low-friction structure. This means that the handrail is in direct contact with the handrail guide profile.
- the areas of the locking element provided for contact with the walls of the groove can have an embossed edge.
- the clamping element and/or the locking element can be designed in such a way that a locking element once clamped between walls of the groove can no longer be released.
- the clamping element and/or the locking element can have interlocking structures, plastically deformable areas, latching elements or securing means such as anaerobic adhesives, securing elements and the like.
- Figure 2 enlarged, the cross section A - A indicated in Figure 1 through the handrail and the handrail guide profile with two roller arrangements arranged next to one another in a first embodiment
- Figure 3 a three-dimensional view of a roller arrangement shown in Figure 2;
- Figure 4 enlarged, the cross section A - A indicated in Figure 1 through the handrail and the handrail guide profile, with a roller arrangement in a second embodiment and with a roller arrangement in a third embodiment.
- Figure 2 shows an enlarged view of the cross section A - A indicated in Figure 1 through the handrail 23 and the handrail guide profile 19.
- the handrail 23 has a C-shaped cross section and is made of an elastic polymer material.
- a roller arrangement 25 is embedded next to one another in each of the two outer grooves 61, 63.
- Such a pairwise arrangement is advantageous so that the width of the handrail 23 (orthogonal to the guide path S) is supported by the roller arrangements 25.
- roller axis 81 does not rotate in the receptacles 77
- complementary structures 91, 92 are formed in the form of surfaces on the roller axis 81 and on the recesses 77. Together, these result in a positive connection with respect to a rotational movement about the axis of rotation R and thus form an anti-rotation device between the roller axis 81 and at least one recess 77.
- FIG. 4 shows an enlarged view of the cross section A - A indicated in FIG. 1 through the handrail 23 and the handrail guide profile 19 as well as a roller arrangement 25 in a second embodiment and a roller arrangement 25 in a third embodiment.
- the basic structure of the second and third embodiments essentially corresponds to the first embodiment.
- the two differ from the first version only in differently designed locking elements 93, 96.
- the roller arrangement 25 of the second embodiment has a wedge-shaped locking element 96. Instead of a support surface 79, a wedge surface 97 is formed on the bearing block 71, on which the wedge-shaped locking element 96 is arranged in a linearly displaceable manner.
- a wedge angle a of the locking element 96 and the wedge surface 97 complement each other, so that the threaded nut 87 of the clamping element 85 can act flatly on the wedge-shaped locking element 96.
- the wedge angle a should be larger than a resulting solid friction angle, which depends on the coefficient of friction between the threaded nut 87, the locking element 96 and the wedge surface 97.
- the areas of the locking elements 83, 93, 96 described above which are intended to rest against the walls 65, 67 of the groove 61, 63 can have an embossed edge 99 (see FIG. 3).
- this embossed edge 99 partially digs into the material of the handrail guide profile 19 and thereby creates a positive connection, which protects the roller arrangement 25 even better against being released from the groove 61, 63 and/or against being moved in the groove 61. 63 along the guide path S, secures.
- a screw is always shown as a clamping element 85 in Figures 2 to 4, it is obvious that further clamping elements 85 such as toggle lever clamping devices, eccentric clamping devices and the like are suitable for the present invention can be used to apply a force to the locking element 83, 93, 96 and to brace it in the groove of the handrail guide profile 19.
- a roller arrangement 25 can also have more than one roller 31, which are rotatably mounted next to each other on the same roller axis 81 or one behind the other on several roller axes 81 in the same bearing block 71.
