1. A pivot sliding door guiding device for a public transport vehicle, comprising
a longitudinal profile formed from a first material for attachment to a door portal, which forms a guiding track, which is U-shaped in cross section, with a bottom surface and two side walls extending therefrom,
a slider, which at least partially reaches directly into the guiding track and is supported on support rollers in a linearly movable manner in the guiding track, with an attachment region for an attachment of a door leaf, wherein a downward load is transferred via the attachment region onto the slider,
wherein
a convex bearing member extending in the longitudinal direction is in each case arranged in the guiding track on the inner faces of the side walls, namely an upper convex bearing member and a lower convex bearing member, wherein the bearing members are arranged such that they extend parallel to each other and are opposite each other,
the support rollers supporting the slider each have a peripherally extending concave guiding groove, by means of which they roll in each case on one of the convex bearing members and are retained in the transverse direction in operation during a linear movement of the slider in the running direction,
the longitudinal profile is formed from a first material which is softer than a second material from which the bearing members are formed,
the attachment region is arranged on the slider such that the center of gravity of the door leaf acts off-center on the slider in the running direction and in the transverse direction,
the slider exclusively has support rollers which, together, serve for the load transfer of the load introduced via the attachment region and acting on the slider,
in operation, at least one support roller rolls on the upper convex bearing member and the other support roller rolls on the lower convex bearing member, wherein both support rollers transfer load of the door leaf via the convex bearing members, wherein all the support rollers arranged on the slider are configured to transfer the load by gravity of the door acting on each slider whereby all support rollers have the same geometry.
