Cylinder lock
First Claim
1. A cylinder lock comprising a cylinder plug (3) which is mounted for rotation around an axially extending axis in a lock cylinder (2) and which includes one or more lock elements, the lock elements including at least one of a row of pins, tumblers and a side bar (7) which are activated directly or indirectly by means of a key (4), the cylinder plug (3) and lock cylinder (2) defining a boundary surface therebetween, and further comprising a latching element (10) which is mounted in the lock cylinder (2) and which in an active position prevents turning of the plug (3) and in a release position permits the plug to be turned, the latching element being urged radially by spring means (15) towards its latching position and coacts with an electrically activated blocking element (11), wherein in one position the blocking element (11) permits the latching element (10) to move radially to its release position, and in another position blocks the latching element in its locking position, wherein the latching element (10) has an axial length which is substantially greater than its thickness or diameter, further wherein the latching element extends axially in parallel with the axially extending axis of the cylinder plug (3) and in a region of the boundary surface between the lock cylinder (2) and the cylinder plug (3), engages in an axially extending groove (3c) or recess in the plug, and moves radially outwardly to its release position, when the blocking element (11), which is mounted in the lock cylinder and has a part with an axial extension extending in a direction parallel to the axially extending axis of the cylinder plug (3), is in its release position and the plug is turned by the key.

Abstract
A cylinder lock (1) comprises a lock cylinder (2) and a key-operated cylinder plug (3). A latching element (10) is located in the region of the boundary surface between the lock cylinder and the plug and is activated by an electrically actuable blocking element (11) which is movable between a release position and a blocking position. The plug cannot be turned by means of the key when the blocking element is in its blocking position. The latching element (10) has a length which is slightly shorter than the axial length of the plug (3).
