Abstract

A tamper evident cargo seal to securely close a cargo container having a pair of doors and at least two spaced apart lock rods, the tamper evident cargo seal including a pair of retention assemblies disposed in engaging relation with the lock rods on opposite sides of a perimeter edge of the door and a cross brace including a generally elongate, rigid construction which is cooperatively associated with the retention assemblies so as to maintain the seal in engagement with the lock rods and prevent removal therefrom, and so as to secure the cross brace in closing relation across the perimeter edge of the door. A lock assembly is provided to secure the cross brace with the retention assemblies, to the container, and at least the cross brace includes a continuous surface pattern defined thereon which is structured to visibly indicate a severing of the cross brace therethrough and a subsequent re-attachment.

Claims

1. To securely close a cargo container having at least one door, a tamper evident cargo seal comprising:

a cross brace structured to span at least one perimeter edge of the door;

a pair of retention assemblies disposed a spaced apart distance from one another on opposite sides of the perimeter edge of the door and structured to engage the cargo container;

said retention assemblies cooperatively disposed with said cross brace and structured to maintain said cross brace in said spanning position across the perimeter edge of the door of the cargo container, thereby securing the door in a closed orientation;

a lock assembly structured to secure said retention assemblies in engaging relation with the cargo container;

said cross brace including a continuous surface pattern defined at least partially thereon, said surface pattern etched into said cross brace and structured to visibly indicate a severing of said cross brace therethrough and a subsequent re-attachment.

2. A tamper evident cargo seal as recited in claim 1 wherein said retention assemblies include said continuous surface pattern thereon.

3. A tamper evident cargo seal as recited in claim 1 further including a surface texturing disposed on said cross brace, said surface texturing including said continuous pattern defined therein.

4. A tamper evident cargo seal as recited in claim 1 wherein said retention assemblies include a pair of retention brackets.

5. A tamper evident cargo seal as recited in claim 4 wherein said lock assembly includes a seal structured to extend through said cross brace and at least one of said retention brackets so as to secure said retention bracket and said cross brace with one another and in secure engagement with the cargo container.

6. A tamper evident cargo seal as recited in claim 1 wherein said retention assemblies are disposed in at least partially surrounding relation to a corresponding lock rod.

7. A tamper evident cargo seal as recited in claim 1 wherein at least one of said retention assemblies is integrally formed with said cross brace.

8. A tamper evident cargo seal as recited in claim 7 wherein said retention assembly includes a generally U-shaped configuration structured to at least partially surround a corresponding lock rod.

9. To securely close a cargo container having at least one door, a tamper evident cargo seal comprising:

a cross brace structured to span at least one perimeter edge of the door;

a pair of retention assemblies disposed a spaced apart distance from one another on opposite sides of the perimeter edge of the door and structured to engage the cargo container;

said retention assemblies cooperatively disposed with said cross brace and structured to maintain said cross brace in said spanning position across the perimeter edge of the door of the cargo container, thereby securing the door in a closed orientation;

a lock assembly structured to secure said retention assemblies in engaging relation with the cargo container;

said cross brace including a continuous surface pattern defined at least partially thereon, said surface pattern engraved into said cross brace and structured to visibly indicate a severing of said cross brace therethrough and a subsequent re-attachment.

10. To securely close a cargo container having at least one door, a tamper evident cargo seal comprising:

a cross brace structured to span at least one perimeter edge of the door;

a pair of retention assemblies disposed a spaced apart distance from one another on opposite sides of the perimeter edge of the door and structured to engage the cargo container;

said retention assemblies cooperatively disposed with said cross brace and structured to maintain said cross brace in said spanning position across the perimeter edge of the door of the cargo container, thereby securing the door in a closed orientation;

a lock assembly structured to secure said retention assemblies in engaging relation with the cargo container;

said cross brace including a continuous surface pattern defined at least partially thereon, said surface pattern including a cross hatched pattern and structured to visibly indicate a severing of said cross brace therethrough and a subsequent re-attachment.

11. To securely close a cargo container having at least one door, a tamper evident cargo seal comprising:

a cross brace structured to span at least one perimeter edge of the door;

a pair of retention assemblies disposed a spaced apart distance from one another on opposite sides of the perimeter edge of the door and structured to engage the cargo container;

said retention assemblies cooperatively disposed with said cross brace and structured to maintain said cross brace in said spanning position across the perimeter edge of the door of the cargo container, thereby securing the door in a closed orientation;

a lock assembly structured to secure said retention assemblies in engaging relation with the cargo container;

said cross brace including a continuous surface pattern defined at least partially thereon, said surface pattern including a diamond pattern and structured to visibly indicate a severing of said cross brace therethrough and a subsequent re-attachment.
