Abstract

Türschloss mit einer Schlossnuss (2), die mit einem Durchbruch (4) zur drehfesten Aufnahme eines Schlossstiftes (1) versehen ist, wobei bei Verdrehung des Schlossstifts (1) um dessen axiale Achse eine Falle des Türschlosses in Öffnungsstellung bewegbar ist, und eine spiralförmig gewickelte Schlossnussfeder (5) vorgesehen ist, deren Wicklungen (11) den lichten Querschnitt des Durchbruchs (4) umgeben. Erfindungsgemäß wird vorgeschlagen, ein erstes freies Ende (6) der Schlossnussfeder (5) mit dem Gehäuse des Türschlosses verbunden ist, und ein zweites freies Ende (7) den lichten Querschnitt des Durchbruchs (4) zumindest abschnittsweise quert.

Figure imgaf001
Door lock with a lock nut (2), which is provided with a breakthrough (4) for non-rotatably receiving a lock pin (1), wherein upon rotation of the lock pin (1) about its axial axis a case of the door lock in the open position is movable, and a spiral wound lock nut spring (5) is provided, whose windings (11) surround the clear cross-section of the opening (4). According to the invention, a first free end (6) of the lock nut spring (5) is connected to the housing of the door lock, and a second free end (7) transverses the clear cross section of the opening (4) at least in sections.
