Abstract

A lock device comprises a cylinder house (10) and a substantially cylindrical cylinder core (20), which is rotatably accommodated in the cylinder house and fixed against axial displacement relative thereto. A tailpiece (40) is rotatably accommodated in the cylinder house and fixed against axial displacement relative thereto. An interconnection means, such as a pin (26), is radially moveable between a disconnecting position, wherein it engages only the cylinder core, and an interconnecting position, wherein it engages both the cylinder core and the tailpiece. By providing an interconnection means that is movable radially to engage a tailpiece, a simple and yet flexible design is achieved.

Claims

1. A lock device comprising:

a cylinder house;

a substantially cylindrical cylinder core which is rotatably accommodated in said cylinder house and fixed against axial displacement relative to the cylinder house;

a tailpiece which is rotatably accommodated in said cylinder house and fixed against axial displacement relative to the cylinder house;

characterized by

an interconnection means which is radially moveable between a disconnecting position, wherein it engages only the cylinder core, and an interconnecting position, wherein it engages both the cylinder core and the tailpiece.

2. The lock device according to claim 1, wherein the tailpiece is cup shaped and comprises a cylindrical portion and an essentially planar bottom.

3. The lock device according to claim 2, wherein the inner diameter of the cylindrical portion of the cup shaped tailpiece is slightly larger than the outer diameter of the cylinder core, and wherein the cylinder core and the tailpiece are so arranged in the cavity that they overlap axially.

4. The lock device according to claim 1, wherein a radial hole in the cylinder core and a hole in the tailpiece are axially aligned to each other.

5. The lock device according to claim 1, wherein the interconnection means comprises a radially movable pin provided in a radial hole in the cylinder core.

6. The lock device according to claim 1, wherein at least one of the cylinder core and the tailpiece is fixated axially by means of a lock pin in the cylinder house engaging a circumferential groove in the cylinder core and the tailpiece, respectively.

7. The lock device according to claim 1, wherein at least one of the cylinder core and the tailpiece is fixated axially by means of a clip provided in a groove in the cylinder house engaging a circumferential groove in the cylinder core and the tailpiece, respectively.

8. The lock device according to claim 1, comprising an actuating means and an electronic authorization means, wherein the actuating means is arranged to move the interconnection means under control of the electronic authorization means.

9. The lock device according to claim 8, wherein the actuating means comprises an electric motor.
