Exterior locking module for a lock

摘要

The invention relates to a module for locking a motor vehicle lock. The aim of the invention is to design an easy-to-make and compact locking module for a lock. Said aim is achieved by a locking module comprising a housing, a switching nut that can be connected to a locking cylinder so as to rotate the switching nut by means of a key, and mechanism for converting a rotary movement of the switching nut into a linear movement to lock and unlock a lock. The mechanism comprises a dog which is linearly moved by a rotary movement of the switching nut. In the mounted state of the locking module, the linear movement of the dog actuates a mechanism that causes the lock to unlock or lock. In order to minimize the number of parts, the switching nut is rotatably mounted by the module housing.

主权项

1. Locking module comprising a housing, a switching nut that can be connected to a locking cylinder so as to rotate the switching nut by means of a key and a mechanism for converting a rotary movement of the switching nut into a linear movement of a dog for locking and unlocking a lock, characterized in that the switching nut is rotatably mounted by the housing and a leg spring is provided, which after a rotation of the switching nut returns a transmission lever, moveable by the switching nut, to an interim position and, wherein the leg spring includes a first leg that abuts the housing and a second leg that can be deflected by pivoting of the transmission lever to bias the spring between the housing and the transmission lever, wherein one of the switching nut or the housing include a first protuberance that extends into a mating first groove defined in the other of the housing or the switching nut, and wherein the mating first protuberance and first groove permit the switching nut to rotate relative to the housing while securing the switching nut from moving relative to the housing.
