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.
Claims8
A door, wherein the door comprises:
- a) a sill with a running rail;
- b) a leaf that can be displaced in parallel with the running rail;
- c) a carriage via which the leaf is supported downward on the running rail;
- wherein the carriage comprises a roller part with a running roller rolling on the running rail and a control cam running at least in sections at an angle to the main plane of the leaf, wherein the roller part is designed to be movable transversely to the main plane of the leaf;
- and the leaf comprises a driving bar with a control pin which is arranged or formed on the driving bar and protrudes into the control cam wherein a movement of the driving bar in the direction of its longitudinal axis causes a movement of the roller part transverse to the main plane of the leaf in order to move the leaf transversely to the running rail;
- wherein the sill comprises a first guide groove extending in parallel with the running rail, wherein a first projection of the carriage extends down beyond the running roller into the first guide groove wherein the carriage can be supported via the first projection on the side wall of the first guide groove and/or the side of the running rail when the leaf is loaded transversely to the extension of the running rail.
