Patent ID: 7765840

Claim:
A dual mode locking padlock constructed for providing two separate and independent locking means in a single, integrated construction, said padlock comprising: A. a housing incorporating a key controlled locking assembly formed therein and a combination controlled locking assembly formed therein and positioned adjacent to the key controlled locking assembly, with each of said locking assemblies being operable independently of the each other; B. a locking member in the form of a shackle constructed for being movable between a locked position and an unlocked position, said unlocked position being controlled by the activation of either the key controlled locking assembly or the combination controlled locking assembly, and comprising a base a) formed at one and of the shackle, b) pivotally mounted to the housing, and c) incorporating a first curved zone and a second curved zone formed along a side edge of the base and positioned adjacent to each other, said first curved zone comprising a concave shape and said second curved zone comprising a convex shape; and C. a trigger member a) pivotally mounted to the housing in cooperating relationship with the base of the locking member, b) incorporating a first curved zone and a second curved zone formed along a side edge of the trigger member and positioned adjacent to each other, said first curved zone comprising a concave shape and said second curved zone comprising any convex shape, c) said first curved zone and second curved zone of the trigger member being positioned in controlling, cooperating, aligned relationship with the first curved zone and second curved zone of the base of the locking member for controlling the articulate pivoting movement of said base, and d) comprising a movement control arm formed thereon and constructed for controllably moving the trigger member relative to the housing in response to the activation of the combination controlled locking assembly or the key controlled locking assembly for positioning the first curved zone and second curved zone thereof in a desired position relative to the first curved zone and second curved zone of the base of the locking member, whereby activation of either the key controlled locking section or the combination controlled locking section causes the trigger member to move between a shackle locking position and a shackle releasing position.
