A carriage arrangement has a driving bar arrangement and a carriage. The carriage has a roller part with a plurality of running rollers. The roller part is displaceable transversely to the longitudinal extent of the carriage with respect to a wing part which can be mounted immovably on a wing. A driving bar of the driving bar arrangement has a control projection which engages in a control slot which is formed obliquely to the longitudinal extent of the carriage. To guide the roller part on the wing part is provided a first roller bearing guide which extends transversely to the longitudinal extent of the carriage. The first roller bearing guide has rolling bodies which are supported both on the wing and roller part so forces acting in the direction of the longitudinal extent of the carriage are channelled away from the wing part into the roller part with low friction.
