Abstract:
A dual locking padlock having a code locking mechanism and an overriding mechanism is disclosed. The housing has a top body as its top portion, a stack of dials and a stack of clutches mounted on a middle portion and a bottom portion having holes to receive screws from the top body for securing the housing. Dials are engagingly mounted on the clutches and only rotatable relative to the clutch when the lock is in the opened mode for changing the combination code. The housing has a spindle having a channel to store the heel of a shackle. The spindle's upward movement allows the shackle to be pulled upward to unlock the padlock. The spindle is allowed to move upward either when a correct combination code is used or when a key activates the overriding mechanism. With the overriding mechanism, the padlock can also be opened with a key.
