Abstract
A lock apparatus including a cylinder lock and an actuation member configured to operate the cylinder lock via rotation of the actuation member with respect to a part of the cylinder lock, wherein: the cylinder lock includes a magnet, and the actuation member includes a smart actuation member circuit, the smart actuation member circuit including: one or more sensors (including one or more magnetic field sensors) configured to sense an action of the smart actuation member circuit with respect to the cylinder lock; and a processor or controller configured to receive information indicative of the sensed action from the or each sensor for use in determining a status of the cylinder lock. Furthermore, smart actuation member circuit, cylinder lock and method of fitting such a cylinder lock are claimed.
Claims23
A lock apparatus including a cylinder lock and an actuation member configured to operate the cylinder lock via rotation of the actuation member with respect to a part of the cylinder lock, wherein:
- the lock apparatus includes a magnet, and
- the actuation member includes a smart actuation member circuit, the smart actuation member circuit including:
- one or more sensors configured to sense an action of the smart actuation member circuit with respect to the cylinder lock, the one or more sensors including one or more magnetic field sensors;
- and
- a processor or controller configured to receive information indicative of the sensed action from the or each sensor for use in determining a status of the cylinder lock,
- wherein the or each magnetic field sensor and the magnet are configured such that rotation of the actuation member to operate the cylinder lock moves the or each magnetic field sensor through a magnetic field of the magnet and the magnet is configured such that this movement changes a sensed polarity of the magnetic field as the or each magnetic field sensor passes the magnet.
A smart key circuit for use with a key which is keyed for a cylinder lock, the smart key circuit including:
- two magnetic field sensors configured to sense an action of the smart key circuit with respect to the cylinder lock;
- and
- a processor or controller configured to receive information indicative of the sensed action from the sensor, including a change in a sensed polarity of a magnetic field for use in determining a status of the cylinder lock,
- wherein a first magnetic field sensor is configured to be located on a first side of a shaft of the key and a second magnetic field sensor is configured to be located on a second side of the shaft.
A cylinder lock including:
- a body;
- a plug configured for rotation with respect to the body, about an axis of rotation, to operate the cylinder lock;
- and
- a magnet, wherein a magnetic axis of the magnet is substantially perpendicular to the axis of rotation.
