ABSTRACT:
A padlock concept consisting of a novel shackle comprised of two tapered shackle elements arranged so that they overlay each other to enclose and opening sufficient to accept the staple of a hasp or attachment device. The shackle elements are connected at one end and when unlocked and unlatched are free to move apart, in a motion causing the two shackle elements to separate, providing a clearance between them, at the unconnected end. Each shackle element includes an opening to allow the staple of the hasp to pass to the common opening. This clearance occurs in opposing elements so that when the elements are brought together or closed the staple of the hasp is completely enclosed by the two shackle elements which substantially fill the space available within the hasp staple. The elements are then latched and locked to provide the security function of a padlock engaged with the staple of a hasp or attachment device.
