Description
- The present invention relates to a door lock of a cargo container, and more particularly, to an improved door lock of a cargo container having a burglarproof function and to easily check a tamper-evident of the container during the transportation of cargo containers.
- In general, a cargo container is widely used as a device to transport cargos, and particularly, cargos are accommodated in a container and the container is transported by a ship when the cargos are imported from foreign countries or exported to foreign countries. When the cargos are transported by a ship, since the containers have to wait for the shipping in a container port for a long time and it takes a long time for the transportation of the containers after the shipping, there is a considerable risk of the cargos accommodated in the containers to be robbed during the transportation and robbery cases frequently occur actually.
- Furthermore, since burglars ingeniously disguise a door lock of the container after robbing the cargos in the container such that an evidence of robbery is so hardly found with the naked eye that the fact of robbery is not perceived for a long time after the robbery of the cargos.
- For this reason, there are continuous efforts to prevent burglar accidents and to easily check tamper-evident of the door lock caused by the robbery. As an example of the efforts, there is
Korean Patent No. 10-0425540 WO 2004/014764 A1 , filed based on the Korean Patent Application claiming a conventional priority and published in 2004 entitled "Cargo Container Door Lock With Theft Prevention Means." - According to the cargo container door lock disclosed in
Korean Patent No. 10-0425540 WO 2004/014764 A1 , since a theft must cut a sealed fastening strap (container seal) in order to open a container door, the tamper-evident can be directly confirmed when the container door is opened by force. - However, according to the cargo container door lock, since a handle and a handle hub are coupled by a rivet, if a theft cuts the rivet off with a grinder or makes a hole with a drilling machine, the cargos in the cargo container may be robbed. The theft may rob the cargos and may ingeniously disguise the rivet after robbery. In a state of being innocent of the fact that the broken door lock is disguised with a new rivet, a person in charge at the time when the cargos are robed does not bear the responsibility for the robbery but a person who release the sealed door lock when the sealed fastening strap (container seal) is released. Therefore, due to this, it may give rise to a trouble of making clear where the responsibility lies.
- If the door lock of a cargo container were implemented such that a theft cannot cut the door lock off with a grinder or make a hole with a drilling machine and it is hard to disguise the door lock, it may be effective to prevent the robbery.
- Therefore, the present invention has been made in view of the above and/or other problems, and it is an aspect of the present invention to provide a door lock of a cargo container having an improved burglarproof function available for preventing robbery of cargos accommodated in the cargo container.
- It is another aspect of the present invention to provide a door lock of a cargo container having a burglarproof function of preventing of a theft from cutting the door lock off with a grinder or from making a hole with a drilling machine and of making the door lock be disguised by the theft.
- In accordance with the present invention, the above and other objects can be accomplished by the provision of a door lock of a cargo container having a burglarproof function comprising: a handle hub, in which a pair of supporting pieces is integrally formed, welded to a side of a locking rod; a rear supporting piece of the supporting pieces having a fastening hole; a front supporting piece of the supporting pieces integrally formed with an inward locking protrusion having a screw coupling groove; a handle including a connecting part formed at a side thereof and having a locking recess with a fastening hole such that the inward locking protrusion of the front supporting piece is inserted into and locked in the fastening hole due to pivot of the handle; and a bolt fastened into the screw coupling groove through the fastening hole of the rear supporting piece.

FIGS. 2 to 6 , thedoor lock 14 according to the embodiment of the present invention, as illustrated inFIG. 2 , includes thehandle hub 20 welded to a side of thelocking rod 12. Thehandle 22 is coupled with thehandle hub 20 such a way that a connectingpart 50 provided at a side of thehandle 22 is coupled with thehandle hub 20. A central portion of thehandle 22 is locked by alocking piece 62 and acatch 64 of afixing plate 60 that is fixed to an outer surface of adoor 10 of the cargo container 2 and coupled with thefixing plate 60. - The
handle hub 20 has a material characteristic and a structural property such that a fasteningbolt 42 cannot be perforated or cut off by a grinder or a drilling machine. Moreover, thehandle hub 20 has a configuration such that, even if a main body is perforated or cut off, it is hard for a theft to disguise the main body due to the robbery trace. The coupling between thehandle hub 20 and thehandle 22 has a structural property such that, even if thebolt 42 of thehandle hub 20 is cut off, thehandle 22 is unable to be released from thehandle hub 20 without releasing acontainer seal 70. - In more detail, the
handle hub 20 of the present invention, as illustrated inFIGS. 3 and4 , is configured in a way that a tungsten carbide plate of high carbon steel having a predetermined thickness is bent to have a U-shape by a forging press such that a pair of supportingpieces insertion portion 32 is defined therebetween. - A rear supporting
piece 30b of the pair of supportingpieces handle hub 20 has afastening hole 34 formed in the central portion thereof, and a front supportingpiece 30a includes aninward locking protrusion 38 having ascrew coupling groove 36 formed at the rear central portion. Aprotrusion 40 is integrally with the front portion of the front supportingpiece 30a. - On the other hand, the
handle 22 coupled with thehandle hub 20, as illustrated inFIG. 5 , has alocking recess 51 formed in the connectingpart 50 and having afastening hole 52 such that theinner locking protrusion 38 of the front supportingpiece 30a of thehandle hub 20 is inserted into thelocking recess 51. - The
fastening hole 34 and thescrew coupling groove 36 of the supportingpieces handle hub 20 are provided for the fastening of thebolt 42 when thehandle 22 is coupled with thehandle hub 20. Theinner locking protrusion 38, as illustrated inFIG. 5 , is provided to serve as a lock when theinner locking protrusion 38 is inserted into thelocking recess 51 of the connectingpart 50 of thehandle 22 and thehandle 22 is pivoted. - When the
handle 22 is inserted into thehandle hub 20 and is pivoted, thehandle 22 is locked and fixed by thehandle hub 20 and thebolts 42 fastened at the rear side of thehandle hub 20 is not exposed over the front side of thehandle hub 20 after thebolt 42 is fastened. Particularly, theprotrusion 40 formed at the front central portion of thefront supporting piece 30a is provided such that a theft cannot perforate the front supportingpiece 30a with a cutting machine such as a drilling machine and thehandle hub 20 is made of a tungsten carbide plate of high carbon steel so that it is next to impossible for the theft to perforate with the cutting machine such as the drilling machine. - In the embodiment of the present invention, the
protrusion 40 integrally formed with the front central portion of thefront supporting piece 30a of the handle hub 30, as illustrated inFIG. 3 , may be formed on the front supportingpiece 30a in the form of a dome shape, or, as illustrated inFIG. 9 , on thefront supporting piece 30a in the form of a curved cone shape. Moreover, theprotrusion 40 may be protruded from the front supportingpiece 30a in the form of a plate having the same size as the front supportingpiece 30a as illustrated inFIG. 10 . - The
protrusion 40 having the above-mentioned shapes makes a drill bit be slid or has a thickness as impossible as perforating with the drill bit. - The coupling of the
handle 22 to thehandle hub 20 will be described in detail with reference toFIGS. 5 to 7 as follows. - When coupling the
handle 22 with thehandle hub 20, firstly thehandle 22 is vertically erected, the connectingpart 50 of the side of thehandle 22 is inserted into theinsertion portion 32 of thehandle hub 20 such that theinner locking protrusion 38 of the front supportingpiece 30a is inserted into thelocking recess 51 of the connectingpart 50. By doing so, thefastening hole 52 of the connectingpart 50 is naturally aligned with thefastening hole 34 of the rear supportingpiece 30a. In this state, as illustrated inFIG. 5 , thebolt 42 is inserted into thefastening hole 34 of the rear supportingpiece 30b from the rear side of thehandle hub 20 and is fastened into thescrew coupling groove 36 of the front supportingpiece 30a. Moreover, if necessary, a head of thebolt 42 is welded in a recess in which the head of thebolt 42 is placed such that thebolt 42 is welded to the rear supportingpiece 30b. - As described above, after the
handle 22 is coupled, thehandle 22 is pivoted toward thedoor 10 about thelocking rod 12 to contact thedoor 10 and thehandle 22 vertically hung is pivoted up counterclockwise, as illustrated inFIG. 7 , to be locked by thelocking piece 62 of thefixing plate 60 fixed to the outer surface of thedoor 10. Next, thecatch 64 is so pivoted that the central portion of thehandle 22 is locked by thelocking piece 62 and thecatch 64 of thefixing plate 60. - The fastened and locked state of the
handle 22 to thehandle hub 20 and by thefixing plate 60 can be clearly understood with reference toFIGS. 6 to 8 . In other words, since thelocking recess 51 formed at the connectingpart 50 of thehandle 22 is downwardly opened, although thebolt 42 of thehandle hub 20 is perforated or cut off, theinward locking protrusion 38 of the front supportingpiece 30a is still locked by thelocking recess 51. Thus, a theft cannot detach thehandle 22 from thehandle hub 20 without releasing thecontainer seal 70. - According to this embodiment of the present invention, since a theft may cut the
catch 64 off with a cutting tool, it is preferable that thecatch 64, like the case of thehandle hub 20, is made of tungsten carbide of high carbon steel and has a thickness of 5 mm to 10 mm. - After the
handle 22 is locked by the lockingpiece 62 and thecatch 64 of the fixingplate 60, a user welds thecontainer seal 70 penetrating thecatch 64 and thehandle 22 to seal thehandle 22. There are various types of container seals 70 such as a bolt, a nut, a fastening strap, and other known types. It is preferable that thecontainer seal 70 is made of high carbon steel, like the case of thehandle hub 20. - In this configuration, it is difficult for the theft to perforate or cut the
handle hub 20 and to cut thecatch 64 and thecontainer seal 70 too. - As described above, according to the present invention, since a theft cannot cut or perforate the door lock of a cargo container with a grinder or a drilling machine, the cargos in the cargo container can be prevented from robbing. Moreover, in addition to the function of preventing robbery, the tamper-evident is easily checked during the transportation of the cargo container so that a measure against the tamper-evident can be easily taken.
- Although, in the preferred embodiment of the present invention, the
inward locking protrusion 38 is formed in thehandle hub 20 in which a pair of supportingpieces recess 51 is formed in the connectingpart 50 of thehandle 22 such that thehandle 22 is inserted into thehandle hub 20 and pivots to be locked by thehandle hub 20, on the contrary, it is possible that the lockingrecess 51 is formed in thehandle hub 20 and the inward locking protrusion is formed in the connectingpart 50 of thehandle 22. Moreover, although thefastening hole 34 and thescrew coupling grove 36 are formed in thehandle hub 20 to couple thebolt 42, those skilled in the art appreciate that thehandle hub 20 can be configured without thebolt 42, thefastening hole 34, and thescrew coupling groove 36. - Although the preferred embodiments of the present invention have been disclosed for illustrative purposes, those skilled in the art will appreciate that various modifications, additions and substitutions are possible, without departing from the scope and spirit of the invention as disclosed in the accompanying claims.
