A recently granted patent (Publication Number: US11946596B2) discloses a self-contained breathing apparatus (SCBA) with a unique locking mechanism for securing the air tank and regulator to a wearable harness. The apparatus includes a back plate with a tank engagement surface and a receiving cradle for the regulator. The locking mechanism consists of two locking members that can move independently between a locked position, where they engage the regulator and cradle, and an unlocked position, allowing for the removal of the air tank only when both members are unlocked. The mechanism also includes biasing members, such as springs, to keep the locking members in the locked position, ensuring secure attachment of the air tank and regulator to the back plate.

Furthermore, the patent also covers a back plate designed to receive the air tank and regulator, featuring the same locking mechanism with two locking members and biasing members. The locking members have latching ends with sloped surfaces that automatically move them to the unlocked position during the insertion of the air tank or regulator. This design allows for easy removal of the air tank when needed while maintaining a secure attachment during use. The locking mechanism's controlling end facilitates the movement of the latching end, ensuring a smooth transition between the locked and unlocked positions. Overall, the patented SCBA and back plate offer a reliable and efficient solution for securing the air tank and regulator in place, enhancing user safety and convenience in critical environments.
