Lock cylinder
First Claim
1. A lock cylinder comprising:
- a housing having a lock member rotatably mounted therein;
a driving shaft for selectively driving the lock member;
a coupling having a pivot member supported in the housing which is positionable to take up a radial coupling position with respect to the driving shaft such that the pivot member couples the driving shaft to the lock member for co-rotation; and
a central element extending through the driving shaft and the lock member, the central element being operatively connected between an outer side and an inner side of the lock cylinder independent of operation of the lock member, the central element further being operatively connected to the coupling for positioning the pivot member in the radial coupling position.

Abstract
A lock cylinder having a housing (2) and mounted rotatably therein a lock member (4), and having a driving shaft (9) for driving the lock member (4) includes a central element (17) which in turn includes electrical conductors passing right through the driving shaft (9) and the lock member (4) in the form of an operative connection from one side of the cylinder to the other existing independently of operation of the lock member. The central element (17) in the form of a rigid body is connected non-rotatably at each end (17'"'"', 17") to a respective unit carrier (12, 18), especially for electronic units. The driving shaft (9) is arranged to be coupled via a coupling (K) with the lock member (4) in a position so that they rotate together.
