Patent attributes
The present invention provides an improved electric lock that allows for electrically controlled retraction of latch bolt to allow for opening of the door in which the lock is installed. The components that allow for retraction are primarily internal to the lock and have means for conducting electrical signals to the lock to allow for remote control of the latch retraction. In some embodiments, the locks comprise an electrically controllable actuator and at least one retraction lever configured to retract the latch bolt against an applied bias. The actuator can be configured with various other internal components such that movement of the other internal components in one direction, such as toward the actuator, causes movement of the latch bolt in the opposite direction, such as away from the actuator. This opposing movement can allow for different electrical arrangements within different locks having relatively small internal spaces.
