Abstract: A lock assembly comprises a plunger reciprocally mounted in a support means, a spring for biasing the plunger in an unlock direction and for holding the plunger in an unlock position, the plunger being movable against the spring bias into a lock position, and link members for holding the plunger in the lock position. The assembly further includes a solenoid having a shaft adapted to operate the link members to release the plunger from the lock position to permit the plunger to be moved by the spring to the unlock position, and an entry console in electrical communication with the solenoid and operable to send an unlock signal to the solenoid upon entry of a selected entry signal.

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.
