Latest Patents
One of his latest patents is the "Inline motorized lock drive for solenoid replacement." This invention features an inline motorized lock drive that can be mounted within a lock housing to drive a sliding locking element between locked and unlocked positions. The design includes a reversible motor with a shaft that has an auger to drive a lock spring, which in turn drives the locking element. The sliding motion of the locking element is axially aligned with the motor axis, significantly reducing friction. The lock drive is modular and emulates a solenoid lock drive with a control circuit. This control circuit is designed to switch between default locked and unlocked positions, emulating both 'fail safe' and 'fail secure' types of solenoid lock drives. It operates on either 12 or 24 volts, allowing it to replace solenoid locks of both voltages. Additionally, it stores power when applied and uses that stored power to return the lock drive to the selected default state when power is removed.
