Abstract
Mechanically or electromechanically positioning a deadbolt used to lock or unlock a door is disclosed. An electromechanical lock can include a deadbolt to be positioned to lock or unlock a door. The deadbolt can be mechanically positioned based on the rotation of a paddle of the electromechanical lock or electromechanically positioned via a motor being turned on to position the deadbolt. A disengagement mechanism can disengage an engagement cog from a worm gear hub of a gear train of the motor upon the mechanical positioning, but remain engaged upon the electromechanical positioning.
Claims13
An apparatus for disengaging a gear train of a motor of an electromechanical lock, comprising:
- a first gear including engagement teeth;
- a release cam positioned upon a tail insert and sheathed within the first gear, the release cam including one or more projections in abutment with the first gear;
- and
- a second gear including engagement pockets, the engagement teeth of the first gear detachably coupled with the engagement pockets of the second gear, with the second gear being directly coupled to the motor;
- wherein the first gear retracts and disconnects from the second gear via rotation of the one or more projections on the release cam in a mechanical mode of operation thereby disengaging the motor from the first gear.
