ABSTRACT:
This device for locking the door of an enclosure notably for housing safety equipments on aircraft or the like comprises means permitting of opening notwithstanding the additional load resulting from the use of a stronger opening spring than in hitherto known devices of this character, without modifying the external shape and dimensions of the device nor increasing the consumption of electric current for energizing the means provided for releasing the device to its open condition, whereby the device remains completely interchangeable with prior art devices not provided with the complemental features of this invention, consisting essentially in the use of a coil spring having several arms and possibly also of an intermediate lever for increasing the lever advantage of hitherto known single-lever devices.
