Abstract:
A solenoid actuated door lock wherein a locking mechanism retains a latch keeper in a locking position to prevent opening of a door, comprising:a locking means for the latch keepera cylindrical solenoid having a co-axial plunger;spring means biasing said solenoid plunger to a rest position, said spring means being compressed when said solenoid is electrically energized to move said plunger axially in the solenoid; means connected to said solenoid for converting linear motion of said plunger to rotary motion of a locking means actuator for maintaining the latch keeper in locked position;said locking means being moveable from a resting, locked position to an unlocked position on energization of the solenoid, said locking means being biased by spring means to its locked position;the latch keeper being normally biased by a spring means in position to engage a door latch;said latch keeper being shaped to permit closing of the latch when the keeper is in biased and locked position, while preventing passage of the latch to open the door unless the latch is activated or the solenoid is activated to move the locking means to its unlocked position,wherein said means for converting linear motion to rotary motion comprises:an actuator having a long axis spaced from and parallel with said plunger;means connecting said plunger and actuator so that said plunger and actuator move together as a unit;linear gear teeth carried by the actuator for engaging circumferential teeth on gear means having an axis of rotation transverse to the actuator long axis;said gear means engaging a locking means which is moveable from a resting, locked position to an unlocked position on energization of the solenoid, said locking means being biased by spring means to its locked positiona latch keeper normally biased by a spring means in position to engage a door latch, said latch keeper permitting closing of the latch when the keeper is in biased and locked position, while preventing passage of the latch to open the door unless the latch is activated or the solenoid is activated to move the locking means to its unlocked position.
