Patent Images
1. A lock cylinder assembly comprising:
- a cylinder housing;
a cylinder rotatable in said cylinder housing;
a first electromagnetic coil and a key;
a pair of spaced apart locking members movable along an axis parallel to a rotational axis of the cylinder, each locking member being urged by a first magnetic field towards a locked position in which rotation of the cylinder is prevented by engagement between the locking members and the cylinder housing;
wherein, in use, when the first electromagnetic coil is energized upon the use of the key, a second magnetic field created thereby causes the locking members to move out of said locked position so as to allow said cylinder to be rotated in said cylinder housing.

Abstract
The present invention relates to a lock cylinder assembly (10) comprising a cylinder housing (12); a cylinder (14); a first electromagnetic coil (48); a first locking member (52); and a key. The cylinder (14) is rotatable in the cylinder housing (12) and the first locking member (52) is urged by a first magnetic field towards a locked position in which rotation of the cylinder (14) is prevented. In use, when the first electromagnetic coil (48) is energised upon the use of the key, a second magnetic field created thereby causes the at least one locking member (52) to move out of the locked position so as to allow said cylinder (14) to be rotated in the cylinder housing (12).
