High security, dual-mode padlock construction
First Claim
1. 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 the shackle member; and
(e) the control member(i) mounted in the housing for arcuate, pivoting movement therein,(ii) 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(iii) responsive to the activation of the combination controlled locking assembly for causing the arcuate, pivoting movement thereof and the controlled movement of the deadbolt locking member with the shackle member and responsive to the activation of the key controlled locking assembly for causing the arcuate, pivoting movement thereof and the controlled movement of the deadbolt locking member with the shackle member;
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 said deadbolt locking member for locking and releasing a cooperating shackle member.

Abstract
By employing a deadbolt construction for virtually eliminating the ability of the shackle to be removed from the housing by the application of excessive force, an effective, easily produced, padlock is achieved which also incorporates two separate and independent locking systems formed in a single padlock. In the present invention, a single housing and a single shackle assembly are employed and are constructed for enabling the shackle to be released from locked engagement with the housing using either a rotatable dial combination construction or a key activated tumbler construction. Furthermore, the rotatable combination defining dials, which controls the release of the shackle using the preset combination, are coaxially aligned, peripherally surrounding the key controlled tumbler/cylinder. As a result, a compact construction is realized, as well as an efficient and effective release construction which is shared by both the combination controlled section as well as the key controlled section.

18. 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 the shackle member; and (e) the control member (i) mounted in the housing for arcuate, pivoting movement therein, (ii) 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 (iii) responsive to the activation of the combination controlled locking assembly for causing the arcuate pivoting movement thereof and the controlled movement of the deadbolt locking member with the shackle member and responsive to the activation of the key controlled locking assembly for causing the arcuate, pivoting movement thereof and the controlled movement of the deadbolt locking member with the shackle member; wherein said combination controlled locking assembly further comprises a plurality of dials, each of said dials peripherally surrounding a tumbler sleeve for cooperating therewith and establishing a pre-designated combination for enabling activation of said control member, and wherein said pre-designated combination can be changed to a new combination by rotating said dials to said new combination when a key is inserted into said key controlled locking assembly, 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 said deadbolt locking member for locking and releasing a cooperating shackle member.
