Abstract (en)
[origin: US4494586A] The invention relates to a safety device for an interlocking mechanism between two sealed enclosures such as found in biological or nuclear environments and which prevents accidental opening of one or the other of two doors closing off the enclosures, which prevents leakage from the enclosures and which may be readily retrofitted to an existing locking system. The locking system comprises a locking ring (36) rotatable between an inoperative position and a locking position for locking the two enclosures and an operating lever for locking the two doors. The safety device includes two locking mechanisms electrically controlled by four prepositioned detection means on the form of microswitches for locking and unlocking the two locking mechanisms.
