Abstract

A tubular hasp for padlocks having U-shaped shackles comprising two tubular elements that attach separately to each side of a closure structure. With the closure in the closed position and the padlock shackle in the unlocked, open position, and rotated away from the closure structure the padlock will fit into the larger tubular element until stopped by the shackle coming into contact with the front wall. The padlock is moved toward the smaller tubular element and the shackle rotated through an opening provided in the front wall of the smaller tubular element until it reaches alignment with the mating hole in the padlock. The shackle is then closed, latched and locked within the padlock body. The combination of these elements provides a secure arrangement of tubular hasp and padlock with the shackle protected from the commonly used methods of forced attack.

A protective tubular hasp for use in connection with a shackle padlock of the type having a lock body and a U-shaped shackle member being movable longitudinally relative to the lock body between a closed, locked position and an open, unlocked position, the U-shaped shackle member having a first leg pivotally carried by the lock body and a second leg freely swingable about the first leg when the shackle member is in the open, unlocked position, said protective hasp comprising:

a first hollow tubular member adapted to receive at least a portion of the shackle padlock within the interior thereof, the longitudinal dimension of said first tubular member being greater than the longitudinal length of the shackle member when the shackle member is in the closed, locked position;
said first tubular member having a first lock body opening and a first shackle member opening in a first wall thereof, said first lock body opening being sized and arranged in said first wall so that the lock body can at least partially pass through said first lock body opening when the shackle member is in the open, unlocked position and rotated to allow such passage, said first shackle member opening being sized and arranged in said first wall to receive at least a portion of the shackle member when the lock body is in said first lock body opening and the shackle member is in the closed, locked position;
a second hollow tubular member being adapted to be arranged adjacent to said first tubular member such that a second wall thereof is opposite said first wall of said first tubular member, and being adapted to receive at least a portion of the shackle padlock within the interior thereof;
said second tubular member having a second lock body opening being sized and arranged in said second wall so that at least a portion of the lock body can at least partially pass through said second lock body opening after passing through said first lock body opening of said first tubular member and a second shackle member opening being sized and arranged in said second wall to receive at least a portion of the shackle member when the lock body is in said first and second lock body openings and the shackle member is in the closed, locked position;
said second tubular member having a front wall, said front wall of said second tubular member having a second leg opening sized and arranged therein so that the second leg of the shackle member can freely swing therethrough when the lock body is in said first and second lock body openings and the shackle member is in the open, unlocked position;
and
said first and second lock body openings and said first and second shackle member openings being sized and arranged so that when the second leg of the shackle member is swung through said second leg opening of said second tubular member, said shackle member may close, latch and lock within the lock body.
