Door locking mechanism for a sterilizer to prevent jamming
A recently granted patent (Publication Number: US11759538B2) describes a door locking mechanism for a sterilizer. The mechanism is designed to secure the door of the sterilizer and ensure it remains locked during operation.
The door locking mechanism includes a locking arm that is hingedly connected to a frame, allowing it to move between a locked position and an unlocked position. The locking arm has a cutaway portion that allows an extendible portion of the door to pass through. A sensor arm is positioned adjacent to the locking arm and is flexible to be displaced by pressure from the extendible portion of the door.
The mechanism also includes a motor that is connected to the operating system of the sterilizer. A camshaft, actuated by the motor, is attached to a cam that is in contact with the locking arm. The cam moves the locking arm between the locked and unlocked positions.
To detect the position of the door, the mechanism includes a closing switch and a locking switch. The closing switch detects displacement of the sensor arm and signals to the operating system that the door is in a latched position. This actuates the cam to move the locking arm into the locked position. The locking switch detects the movement of the locking arm into the locked position and signals to the operating system that the door is securely locked, ceasing the operation of the motor.
The mechanism also features a resilient member that biases the locking arm into the locked position and a manual release lever that allows for manual unlocking of the door.
Overall, this door locking mechanism provides a secure and reliable way to lock the door of a sterilizer during operation. The combination of the locking arm, sensor arm, motor, and switches ensures that the door remains locked and prevents any accidental opening. The inclusion of a manual release lever allows for easy unlocking of the door when necessary.
