High security, dual-mode padlock construction

A padlock constructed for providing two separate and independent locking means in a single integrated construction, said padlock comprising:

• A. a housing constructed for retaining a combination controlled locking assembly and a key controlled locking assembly in cooperating, controlling relationship with a deadbolt locking member;
• B. a combination controlled locking assembly and a key controlled locking assembly mounted in the housing in coaxial, aligned relationship with each other, thereby establishing a dual mode locking construction configured and contained in a small, compact area;
• C. a shackle member mounted in the housing and movable between a first, housing engaged and locked position and a second, housing disengaged and unlocked position, each of said positions being controlled by activation of the combination controlled locking assembly or the key controlled locking assembly;
• D. said deadbolt locking member mounted in the housing in cooperating relationship with a control member and at least one end of a leg of the shackle member;
• and
• E. a control member
• a) mounted in the housing for movement therein,
• b) positioned in cooperative association with the deadbolt locking member for controlling the movement of the deadbolt locking member between a first shackle engaged position and a second shackle released position for causing such shackle member to move between its first housing engaged and locked position and its second, housing disengaged and unlocked position, and
• c) responsive to the activation of the combination controlled locking assembly and the key controlled locking assembly for causing the movement thereof and the controlled movement of the deadbolt locking member with the shackle member;
• wherein said control member is configured for movement along a first axis and said leg of the shackle member is configured for movement along a second axis parallel to said first axis;
• whereby a padlock construction is attained which achieves a compact construction having a coaxially aligned combination controlled locking assembly and key controlled locking assembly, with both assemblies controlling the movement of the deadbolt locking member for locking and releasing a cooperating shackle member.
