Abstract

An adjustable height corner fitting for a shipping container including a substantially hollow rectangularly shaped block having a bottom wall, end walls and side walls is disclosed. An elongated aperture is located in the bottom wall and is adapted to cooperate with a locking mechanism in order to lock the shipping container to the platform of a vehicle. Also provided is a substantially rectangularly shaped plate that is complementary to the bottom wall and is adapted to be temporarily attached thereto in order to increase the height of the block. The plate also has an elongated aperture therein which is complementary to the aperture in the bottom wall. When the plate is attached, the apertures in the plate and in the bottom wall are in alignment, but the plate causes the corner fitting to extend downwardly approximately a half an inch below the container for shipment on a truck, boat or rail car. With the plate removed, the bottom of the corner fitting is essentially flush with the bottom of the container thereby allowing the container to be transported by cargo plane.

Claims

1. An improved corner fitting for a shipping container comprising:

a hollow rectangular block having a bottom wall, at least one end wall and at least one side wall;

an elongated aperture located in said bottom wall adapted to cooperate with a locking mechanism in order to lock said shipping container to a platform of a vehicle, and

a substantially rectangularly shaped plate complementary to said bottom wall and adapted to be attached thereto in order to increase the height of said block, said plate having a single elongated aperture therein complementary to said aperture in said bottom wall, said apertures being in alignment with each other when said plate is attached to said bottom wall, and means for temporarily attaching said plate to said bottom wall of said block.

2. The improved corner fitting as claimed in claim 1 wherein said means for temporarily attaching said plate to said bottom wall of said block includes said plate having a plurality of vertically extending projections and said bottom wall having a plurality of complementary holes adapted to receive said projections.

3. The improved corner fitting as claimed in claim 2 wherein said projections are in the form of upstanding pins.

4. The improved corner fitting as claimed in claim 3 further including means for temporarily preventing said pins from being removed from said holes when said plate is properly positioned on said bottom wall.

5. The improved corner fitting as claimed in claim 1 wherein said bottom wall and said end wall intersect each other and include a chamfered area at the intersection.

6. The improved corner fitting as claimed in claim 5 wherein said plate has an upper surface and includes a portion that is complementary to and is adapted to mate with said chamfered area of said bottom wall.

7. The improved corner fitting as claimed in claim 5 wherein said bottom wall and said side wall intersect each other and include a chamfered area at the intersection.

8. The improved corner fitting as claimed in claim 7 wherein said plate includes portions that are complementary to and are adapted to mate with both of said chamfered areas of said bottom wall.

9. An improved corner fitting for a shipping container comprising:

a hollow rectangular block having a bottom wall, at least one end wall and at least one side wall;

an elongated aperture located in said bottom wall adapted to cooperate with a locking mechanism in order to lock said shipping container to a platform of a vehicle, and

a substantially rectangularly shaped plate complementary to said bottom wall and adapted to be attached thereto in order to increase the height of said block, said plate having an elongated aperture therein complementary to said aperture in said bottom wall, said apertures being in alignment with each other when said plate is attached to said bottom wall, and means for temporarily attaching said plate to said bottom wall of said block, said attaching means including said plate having a plurality of vertically extending projections and said bottom wall having a plurality of complementary holes adapted to receive said projections.

10. The improved corner fitting as claimed in claim 9 wherein said projections are in the form of upstanding pins.

11. The improved corner fitting as claimed in claim 10 further including means for temporarily preventing said pins from being removed from said holes when said plate is properly positioned on said bottom wall.

12. An improved corner fitting for a shipping container comprising:

a hollow rectangular block having a bottom wall, at least one end wall and at least one side wall, said bottom wall and said end wall intersecting each other and including a chamfered area at the intersection;

an elongated aperture located in said bottom wall adapted to cooperate with a locking mechanism in order to lock said shipping container to a platform of a vehicle, and

a substantially rectangularly shaped plate complementary to said bottom wall and adapted to be attached thereto in order to increase the height of said block, said plate having an elongated aperture therein complementary to said aperture in said bottom wall, said apertures being in alignment with each other when said plate is attached to said bottom wall, and means for temporarily attaching said plate to said bottom wall of said block.

13. The improved corner fitting as claimed in claim 12 wherein said plate has an upper surface and includes a portion that is complementary to and is adapted to mate with said chamfered area of said bottom wall.

14. The improved corner fitting as claimed in claim 12 wherein said bottom wall and said side wall intersect each other and include a chamfered area at the intersection.

15. The improved corner fitting as claimed in claim 14 wherein said plate includes portions that are complementary to and are adapted to mate with both of said chamfered areas of said bottom wall.
