Abstract
Abstract A rail-suspended carriage for movable partition walls has a carriage body provided with an axle on which a pair of wheels are mounted which can engage a rail along which the carriage is to travel. Turnable guide rollers are provided, each being adapted to roll along a rail in lateral engagement therewith and each being turnable about a first vertical axis and the latter in turn being pivotable about a second vertical axis paralleling it. A track roller is turnable about another vertical axis laterally offset from and paralleling the first and second axis, and a motion-transmitting arrangement is provided which enforces pivotal movement of the first axis of one guide roller about the second axis thereof in one direction, if the first axis of the other guide roller is pivoted about its second axis in an opposite direction, and vice versa.
