Abstract: For mounting a folding/sliding door, a support is connected to a hinge arm of a hinger mounted in the upper outer end area of an outer door leaf in a position in which the side of the retaining part that attaches to the hinge arm is located in the extension of the bearing part. The folding/sliding door can then be joined by its inner leaf via hinges, preferentially standard double-link hinges, to a side panel of the body. The pre-fitted support, already connected to the hinge arm of the outer door leaf, can then be introduced and locked into the guide channel together with its carriage part. First, the carriage part is swiveled through 90 degrees around the retaining part so as to position the carriage part within the longitudinal slot of the guide channel. The carriage part is then locked in place by turning the hammer-shaped head through 90 degrees by means of its supporting pin.
