Abstract: A carriage has a wing part which can be fastened to a wing and a roller part which is displaceable on a running rail. The wing part is displaceable in a positively controlled manner transversely to the running rail. The roller part has a height-adjustable roller upper part. The vertical adjustability of the roller upper part with respect to a roller holder of the roller part is achieved by means of an adjusting element which is displaceable by means of an adjusting screw. The adjusting element is preferably supported with at least one adjusting element bevel on a pendulum axle of the running roller holder and/or on an upper part bevel of the roller upper part.

Abstract: A door including a barrier-free sill is disclosed. A reliable seal or transverse support of the leaf in the event of wind pressure or an attempted break-in is achieved by at least one projection of a carriage, which extends into a guide groove. The projection extends further down than a running roller of the carriage. This enables the design of a particularly stable and yet barrier-free door.

Abstract: A door including a barrier-free sill is disclosed. The sill preferably has recesses on its upper side, the width of the recesses being less than 50 mm and/or the depth of the recesses being less than 3 mm. A leaf can penetrate the upper side in a leaf recess. The leaf may fall below the vertically uppermost dimension of a running rail. Using at least one projection of a carriage that extends into a guide groove, it is possible to reliably seal or transversely support the leaf in the event of wind pressure or a break-in attempt. The projection preferably extends further down than a running roller of the carriage. This enables the design of a particularly stable and yet barrier-free door.

Abstract: 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.

Abstract: A pressing device has a roller part, a control part and a fastening part. The pressing device can be mounted to a leaf of a window or door. The roller part is movable in the mounted state of the pressing device, in particular, vertically relative to the control part. The control part is movable horizontally to the fastening part in a positively controlled manner. A spring element is provided between the control part and the roller part in order to subject the roller part, in addition to the force of gravity, to a downwardly directed spring force, i.e., towards the running rail.

Abstract: A fitting arrangement for a window or a door has a drive bar with a through-hole. A control pin and/or a counter element of the fitting arrangement is/are passed through the through-hole and connected to one another such that the control pin is captively retained on the drive bar. The control pin is preferably connected to the counter element without the use of tools. Particularly preferably, a spring element is provided which latches the control pin by pressing the control pin and the counter element axially together. The spring element can be designed in the form of a circlip which, in the not yet assembled state, is arranged on the control pin or the counter element.
