1. Field of the Invention
The present invention relates to security systems and more particularly, to security bar seals for shipping containers.
2. Description of the Related Art
Millions of shipping containers flow through ports all over the world on a daily basis. It is imperative to keep the contents of those shipping containers secure and not have them compromised. In addition to theft of contents, there is a need to ensure that shipping containers are not used as vehicles to transport illegal narcotics, illegal weapons, and otherwise unauthorized matter.
Several designs for bar seals have been designed in the past. Applicant, however, is not aware of any bar seal that includes a single-use security bar seal system comprising identification matching codes on all individual parts and electrical means for determining severance of the bar assembly.
A single-use security bar seal assembly for shipping containers, comprising an elongated bar member having first and second ends, wherein the first end has a protrusion. The elongated bar member has a first aperture of a predetermined depth between the first and second ends and a second aperture of the predetermined depth between the first aperture and the second end. The elongated bar member further has at least one through hole in between the second aperture and the second end and electrical means for detecting severance of the elongated bar member.
A support assembly has a first U-shaped member that has first and second slots to receive the second end therethrough. A receiving bracket has a second U-shaped member connected to a housing. The second U-shaped member has third and fourth slots to receive the second end. The housing comprises locking means to lock the elongated bar member to the support assembly and the receiving bracket.
The locking means comprises the receiving bracket having a third aperture with a snap ring to receive a locking pin. The locking pin has at least one groove to receive the snap ring when the locking pin is aligned with the at least one through hole and presented into the third aperture with sufficient force to overcome the snap ring.
The electrical means comprises the first and second apertures connected to each other by an element capable of an uninterrupted succession or flow of electrical current. The first and second apertures may be tested with a continuity testing assembly to detect if the elongated bar member has been severed. The element is a metallic strip embedded within the elongated bar member between the first and second apertures.
The elongated bar member, the support assembly, and the receiving bracket have matching identification codes and secret codes.
The continuity testing assembly comprises a wand and an insert connected to one another by a wire. The continuity testing assembly is used to detect if the metallic strip has been severed.
The continuity testing assembly comprises a light emitting or sound producing alarm for negative electrical continuity and/or light emitting or sound producing alarm for positive electrical continuity.
The first and second U-shaped members snugly fit around door bars of a container and in the preferred embodiment the container is a shipping container.
It is one of the main objects of the present invention to provide a bar seal for shipping containers that is effective against tampering.
It is another object of this invention to provide a bar seal for shipping containers that is durable.
It is yet another object of this invention to provide such a device that is inexpensive to manufacture and maintain while retaining its effectiveness.
Further objects of the invention will be brought out in the following part of the specification, wherein detailed description is for the purpose of fully disclosing the invention without placing limitations thereon.
With the above and other related objects in view, the invention consists in the details of construction and combination of parts as will be more fully understood from the following description, when read in conjunction with the accompanying drawings in which:
a shows the first perspective view of the receiving bracket with the bar member in position to be locked with the pin.
b shows the first perspective view of the receiving bracket locking the bar member with the pin.
c is a cut view of the receiving bracket locking the bar member with the pin taken along the lines 3c—3c, as seen in
a is a cut view of the bar member taken along the line 6a—6a, as seen in
a represents a close-up perspective view of the instant invention mounted onto the shipping container bars.
b represents a perspective view of the instant invention mounted on a shipping container bars and being tested for severance of the bar member.
Referring now to the drawings, where the present invention is generally referred to with numeral 10, it can be observed that it basically includes receiving bracket 20, support assembly 60, and bar member 80.

It is noted that the receiving bracket 20, support assembly 60, and bar member 80 have matching identification codes, wherein each of the components have matching codes. The receiver may inspect each of receiving bracket 20, support assembly 60, and bar member 80 to ensure that they do in fact have matching codes. In the event the receiver determines that the matching identification codes do not match, the receiver is on notice that the contents of the shipping container 150 may have been disturbed or otherwise tampered with.
Furthermore, in addition to the matching identification codes, instant invention 10 may comprise random secret codes made up of number(s), word(s), and/or any symbol that may be stamped on receiving bracket 20, support assembly 60, and bar member 80. The secret codes are stamped on any of receiving bracket 20, support assembly 60, and bar member 80 and are known only by the sender and receiver in the preferred embodiment. Before severing bar member 80 to open the shipping container 150, the receiver, knowing the secret codes, can determine if any of receiving bracket 20, support assembly 60, and/or bar member 80 were replaced after being sent by the sender. In the event the receiver determines that the secret codes do not match those originating from the sender, the receiver is on notice that the contents of the shipping container 150 may have been disturbed or otherwise tampered with.
The foregoing description conveys the best understanding of the objectives and advantages of the present invention. Different embodiments may be made of the inventive concept of this invention. It is to be understood that all matter disclosed herein is to be interpreted merely as illustrative, and not in a limiting sense.
