designed by Michael Schmidt and Markus Michalski. In high-quality civic/commercial and residential construction, the trend is towards minimalism. Cases in point are non-rebated flush doors with concealed hinges or lever sets that do without a key rose.
Michael Schmidt and FSB have rethought the locking of a door and integrated it directly into the door handle rose. Based on the “ballpoint pen principle”, the door handle is locked when the push-button is pressed once and released again when it is pressed again. In keeping with the spirit of universal design, the lockable lever handle can be conveniently operated with one hand.
The privacy button is located on the inside of the door of a bathroom, WC or other private rooms. An emergency opening function integrated on the outside ensures safety in the event of an emergency.
