Claim:
A high security padlock constructed for ease-of-use as well as for substantially eliminating the ability of unauthorized persons from opening the padlock, said padlock comprising: a housing incorporating a combination section incorporating a first, central elongated bore longitudinally extending through the center of the housing, and a second elongated bore formed in juxtaposed, spaced, substantially parallel relationship to the first central bore; a plurality of dial receiving zones formed in the housing, each of said receiving zones extending substantially perpendicularly to the axis of the first central bore, and defined by two juxtaposed, spaced, parallel facing surfaces, each of said surfaces extending perpendicularly to the central axis of the central bore; and at least one elongated release channel formed in the first central bore and axially extending therewith, said elongated release channel defining a zone for enabling the opening of the padlock; an elongated shaft mounted in the first central bore and constructed for axial, longitudinal movement therein, said shaft comprising a first end and a second end; a shackle comprising a generally J-shape, incorporating a short leg having a terminating end constructed for cooperative locking and unlocking engagement with the housing, and also incorporating a notched zone formed in said short leg adjacent to the terminating end, and a long leg cooperatively mounted in the second elongated bore of the housing for axial movement and pivoting movement relative thereto, and incorporating a notched zone formed therein and positioned in cooperating alignment with the notched zone of the short leg; a plurality of tumbler sleeves, each of said tumbler sleeves being rotationally mounted to the elongated shaft for rotational movement about the central axis thereof, and incorporating at least one radially extending fin formed on the outside surface thereof and constructed for cooperative association with at least one of the elongated release channels for preventing axial movement of the shaft as well as enabling the axial movement thereof when each of said radial fins are positioned in one of the elongated release channels; a plurality of dials, each of said dials mounted in a dial receiving zone of the housing, peripherally surrounding a tumbler sleeve for cooperating therewith; and two shackle locking members mounted in the housing in cooperating relationship with the notched zones of the shackle; and a cam member mounted to the first terminating end of the shaft and positioned in cooperating relationship with the notched zones of the shackle and the shackle locking members for controllably guiding and moving the locking members between a first locked position wherein a portion of each locking member is engaged in one notched zone of the shackle, and a second unlocked position wherein the locking members are disengaged from the notched.
