Patent ID: 7946142

Claim:
A padlock hasp assembly comprising: a first hasp member and a second hasp member comprising interface contours including complimentary shaped protrusions and recesses that mate with one another; and a locking assembly housed in said first hasp member, said locking assembly comprising a cylinder lock including a tumbler adapted to bring a locking element into locking engagement with a first notch formed in a locking bolt, said locking bolt comprising a generally cylindrical shank with said first notch and a second notch formed therein, said locking bolt being arranged for sliding motion through a first bore formed in said first hasp member, and when said second hasp member is aligned with said first hasp member, said locking bolt is slidable into a second bore formed in said second hasp member so as to lock said first and second hasp members together; wherein said cylinder lock also moves said locking element out of locking engagement with said first notch, so as to permit sliding said locking bolt in a direction outwards of said first hasp member, and wherein as long as a portion of said shank between said first and second notches slides past said locking element, a thickness of said shank prevents said locking element from moving back inwards and when said second notch moves in alignment with said locking element, said second notch permits said locking element to move back inwards, thereby locking against said second notch and preventing said locking bolt from being pulled completely out of said first hasp member.
