Claims
- 1. (canceled)
- 2. A security device for a kingpin, comprising:
a vertically-oriented tube having upper and lower ends and an inner diameter sufficient to slidably receive a kingpin of predetermined dimensions therein: a conical shaped shell mounted on the tube and tapering from a large diameter at an upper end to a small diameter at a lower end, the shell having a central axis coaxial with a central axis of the tube; and an operable lock mounted on said tube, said lock operable between a locked position securing a horizontal pin in a first position projecting within an interior cavity of the tube, and an unlocked position permitting movement of the pin to a second position withdrawn from the interior cavity of the tube; wherein said shell is formed of a plurality of gussets projecting radially outwardly from the tube.
- 3. The security device of claim 2, wherein said gussets are generally triangular in shape.
- 4. The security device of claim 2, further comprising a lock housing substantially enclosing said lock on the tube, said housing having a horizontal bore formed therethrough and communicating with the interior cavity of the tube, and wherein:
said lock is a plunger-type lock with a cylindrical plug coaxially mounted to an outward end of the pin; said plug is operably mounted within a cylinder for movement between a locked position within the cylinder and an unlocked position projected at least partially out of the cylinder; and said lock cylinder is mounted within the bore and coaxial therewith.
- 5. (Canceled)
- 6. In combination:
a cargo container having a kingpin depending from a bottom surface thereof; said kingpin being substantially cylindrical in shape, with an annular notch around the circumference thereof, space above a lower end; and a security device removably connected to the kingpin to Prevent connection of the kingpin to a fifth wheel plate on a tractor, said security device comprising:
a vertically-oriented tube having upper and lower ends and an inner diameter sufficient to slidably receive said kingpin therein; a conical shaped shell mounted on the tube and tapering from a large diameter at an upper end to a small diameter at a lower end, the shell having a central axis coaxial with a central axis of the tube; and an operable lock mounted on said tube, said lock operable between a locked position securing a horizontal pin in a first position projecting into the kingpin notch within the tube, and an unlocked position withdrawn from the kingpin notch; wherein said shell is formed of a plurality of gussets projecting radially outwardly from the tube.
- 7. The combination of claim 6, wherein said gussets are generally triangular in shape.
- 8. The combination of claim 6, further comprising a lock housing substantially enclosing said lock on the tube, said housing having a horizontal bore formed therethrough and communicating with the interior cavity of the tube, and wherein:
said lock is a plunger-type lock with a cylindrical plug coaxially mounted to an outward end of the pin; said plug is operably mounted within a cylinder for movement between a locked position within the cylinder and an unlocked position projected at least partially out of the cylinder; and said lock cylinder is mounted within the bore and coaxial therewith.
- 9. A security device for a kingpin, comprising:
a vertically-oriented tube having upper and lower ends and an inner diameter sufficient to slidably receive a kingpin of predetermined dimensions therein; a conical shaped shell mounted on the tube and tapering from a large diameter at an upper end to a small diameter at a lower end; said shell having a central axis coaxial with a central axis of the tube, and including a plurality of gussets projecting outwardly from the tube; and an operable lock mounted on said tube, said lock operable between a locked position securing a horizontal pin in a first position projecting within an interior cavity of the tube, and an unlocked position permitting movement of the pin to a second position withdrawn from the interior cavity of the tube.
