ABSTRACT:
A locking device is used to lock a closure, such as a garage or metal door and includes a housing to receive a padlock. The housing is configured to obstruct access to the padlock shackle so that it cannot be cut with bolt cutters. The housing also includes a pair of aligned openings which allow a shackle of a second padlock to be passed through the housing to prevent unlocking movement of the first padlock. In one embodiment of the invention, the locking device includes a bolt mechanism on the inside of the housing which is generally hook-shaped and positioned to abut a locked padlock supported on the inside of the housing. When the padlock is unlocked, the padlock body moves out of the way of one end of the hook-shaped structure thereby allowing the bolt to be retracted to an unlocked position. In a second embodiment of the invention, the padlock body is suspended in the housing so that, in an unlocked position thereof, a tongue is capable of passing through the opening between the shackle and the padlock body. In a locked position of the padlock, the tongue is encapable of being withdrawn.
