Electronic lock with blocker and retainer for door security
A recently granted patent (Publication Number: US11920378B2) discloses a storage area with a unique lock system. The lock includes a blocker that can be moved between an extended position, locking the door, and a retracted position, unlocking the door. An electronic controller is coupled to the lock to selectively block the movement of the blocker actuator. Additionally, a retainer and retainer blocker are included in the lock system to maintain the retainer in a blocking position, preventing the actuation of the blocker. The retainer blocker comprises at least one stop that can be rotated into a stop position to prevent the rotation of the retainer, ensuring the security of the storage area.
Furthermore, the lock system includes a biasing element, such as a torsion spring, that can position the retainer between the blocking and unblocking positions. The interaction between the retainer, retainer blocker, and biasing element provides a robust and secure locking mechanism for the storage area. The patent also details the use of a worm wheel, motor, and worm screw to actuate the stop within the retainer blocker, adding an additional layer of complexity and security to the lock system. Overall, the innovative design of this lock system offers enhanced protection and control over access to the storage area, making it a valuable addition to the field of security technology.
