Laufwagen für einen verfahrbaren Gegenstand, insbesondere für eine automatische Schiebetür oder ein automatisches Schiebetor mit zumindest einer Schiebetür oder einem Schiebetor

摘要

The carriage has a running roller (15) rolling on a running rail (13) for supporting the object (1) and a counter rail (25) on which a counter roller (27) rolls, whereby the running and counter rollers have an associated rocker-shaped running mechanism bearer. The wt. of the object bears at least partly on an engagement point on the bearer offset wrt. the roller axis. The counter roller axis is arranged on the opposite side of the running roller axis from the engagement point. The load wt. forces the counter roller onto the counter rail. An Independent claim is also included for a sliding door or gate.
