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.
Claims15
A door, wherein the door comprises:
- a) a sill with a running rail;
- b) a leaf configured to 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 recesses on the upper side whose respective maximum horizontal width perpendicular to the running rail does not exceed 50 mm and/or whose respective maximum vertical depth does not exceed 3 mm.
