Cargo security seal

A cargo security seal comprising a lock body having an elongated bore of uniform diametral size, a groove in said bore, and an elongated bolt having opposite ends and a diametral size smaller than said bore, said bolt having a groove therein and an expandable ring in said bolt groove, said bolt groove having two generally planar spaced apart lock surfaces extending generally perpendicular of said bolt, said bore groove having two generally planar spaced apart lock surfaces extending generally perpendicular to said bore, said expandable ring in said bolt groove, said ring being collapsible from a diameter larger than the diameter of said bolt to a diameter smaller than the diameter of said bolt, said bolt having a diameter substantially filling said bore, said bolt being locked in said bore by inserting one of said ends of said bolt into said bore and moving said lock body toward the other of said ends of said bolt, whereby said expandable ring expands into said bore groove to position said expandable ring between said lock surfaces of said bore groove and said lock surfaces of said bolt groove thereby preventing said bolt from being removed from said bore by the engagement of said lock surfaces with said expandable ring, said bolt and said bore preventing access to said expandable ring without the destruction of said lock body or said bolt.

A cargo security seal comprising an elongated bolt having opposite ends, a lock retainer on said bolt adjacent at least one of said opposite ends, and an anti-tampering device on said bolt between the other of said opposite ends and said lock retainer, and a lock body with a lock therein removably securable to said bolt at said one end by said lock retainer, said anti-tamper device being adjacent to said lock body, said lock retainer and said anti-tampering device preventing access to said lock, whereby said lock body cannot be removed from said bolt without destruction of said bolt or lock body, said bolt having lock retainers and anti-tampering devices adjacent to both of said ends, and two lock bodies, one for each end.

A cargo security seal comprising an elongated bolt having opposite ends, a lock retainer on said bolt adjacent at least one of said opposite ends, and an anti-tampering device on said bolt between the other of said opposite ends and said lock retainer, a lock body with a lock therein removably securable to said bolt at one of said opposite bolt ends by said lock retainer and said anti-tampering device adjacent to said lock body, said lock retainer and said anti-tampering device preventing access to said lock, whereby said lock body cannot be removed from said bolt without destruction of said bolt or lock body, said bolt being tubular having an interior passageway extending therethrough and has a global positioning system being positioned within said passageway.

A cargo security seal comprising an elongated bolt having opposite ends, a lock retainer on said bolt adjacent at least one of said opposite ends, and an anti-tampering device on said bolt between the other of said opposite ends and said lock retainer, and a lock body with a lock therein removably securable to said bolt at said one end by said lock retainer and said anti-tampering device adjacent to said lock body, said lock retainer and said anti-tampering device preventing access to said lock, whereby said lock body cannot be removed from said bolt without destruction of said bolt or lock body, said bolt being tubular having an interior passageway extending therethrough and has an electronic tamper evident device begin positioned within said passageway.

A cargo security seal comprising an elongated bolt having opposite ends, a lock retainer on said bolt adjacent at least one of said opposite ends, and a anti-tampering device on said bolt between the other of said opposite ends and said lock retainer, and a lock body with a lock therein removably securable to said bolt at said one end by said lock retainer and said anti-tampering device adjacent to said lock body, said lock retainer and said anti-tampering device preventing access to said lock, whereby said lock body cannot be removed from said bolt without destruction of said bolt or lock body, said bolt being step diametered and said lock body is a step diametered cap having a closed end and an open end, said step diametered cap having a larger step diametered portion adjacent said open end and a smaller step diametered portion adjacent said closed end, said cap having a groove in said smaller step diametered portion, said bolt having a smaller step diametered portion adjacent said one end, and a groove in said smaller step diametered portion of said bolt, both said grooves having a bottom and upstanding side wall generally perpendicular of said bolt and cap, respectively, said step diametered portions of said bolt and cap being generally complementary when said grooves are aligned.

A cargo security seal comprising a lock body having an elongated bore of uniform diametral size extending into said body, a groove in said bore, an expandable ring in said groove, said ring being expandable from a diameter smaller than the diameter of said bore to a diameter larger than the diameter of said bore, an elongated bolt having opposite ends and a diametral size smaller than said bore, said bore and bolt having diametral sizes chosen to provide sliding tolerances, said bolt having a groove therein into which said expandable ring may expand whereby said bolt may be positioned within said bore and locked therein by said expandable ring expanding into said groove of said bolt, said bolt substantially filling said bore on both sides of said expandable ring and essentially closing said bore to access to said expandable ring said bolt groove having two generally planar spaced apart lock surfaces extending generally perpendicular of said bolt, said bore groove having two generally planar spaced lock surfaces extending generally perpendicular to said bore whereby said lock body cannot be removed from said bolt without destruction of said bolt or said lock body.
