Definitions

  • the invention relates to a heavy-duty cargo container door lock for securing doors of intermodal containers, such as those which may be used on ships, rail lines and trucks, against theft.
  • An intermodal container is a large, standardized shipping container, which is designed and built for intermodal freight transport, which means that these containers can be used across different modes of transport - from ship to rail to truck - without unloading and reloading their cargo.
  • Intermodal containers are primarily used to store and transport materials and products efficiently and securely in a global containerised intermodal freight transport system.
  • Intermodal containers exist in many types and a number of standardized sizes, but ninety percent of the global container fleet are so-called “dry freight” or “general purpose” containers, which are durable closed steel boxes, mostly of either 6m or 1 2m standard length (although lengths of containers can vary from 2.4m to 17.1 m), and typically between 2.6m and 2.9m in height.
  • the containers are known by different names, such as cargo or freight containers, ISO containers, shipping, sea or ocean containers, container vans or container boxes.
  • intermodal container is used to designate all these various types of containers used across different modes of transport, as well as containers that are integrally formed with and form part of a truck body.
  • These intermodal containers are typically rectangular, closed box models, with steel doors fitted at one end of the container within a door frame and made of corrugated weathering steel.
  • Each container typically includes two steel door leaves that are hingedly connected to rear corner posts of the container with drop forged steel hinge blades. The blades allow 270-degree opening, which allow the doors to swing back against a container side wall.
  • a lock box which is a steel box, typically welded to the right-hand door, overlaps a staple welded to the left-hand door.
  • a padlock can be attached inside the lock box through the staple to protect the lock box from direct attack, hindering attempts to gain entry into the container.
  • Each door is fitted with two vertically extending, elongate lock rods which extend between the bottom and the top of the doors and which are used to enable opening, closing and locking of the doors.
  • Each lock rod terminates at opposite ends thereof (i.e., top and bottom) in a cam, which is welded in place.
  • Cam keepers also known as knuckles, are welded to a frame of the container and are configured such that the cams releasably engage the cam keepers. The action of engaging the cams to the keepers forms an anti-racking function.
  • a door handle rotates the lock rods to initiate a door opening process by forcing the cams out of their keepers.
  • Intermodal containers are often the target of break-ins and burglary, and cargo theft results in millions of dollars of losses annually.
  • the doors of such containers have always been the most vulnerable area for illegal entry into a cargo space.
  • Several interlocking devices have been developed to protect the doors of trailers and/or containers against unauthorised opening. These include, for example, lock rod clamps and crossbar locks of heavy-duty steel tubing, that clamp over the lock rods and that prevent the primary doors’ handle from turning. They are designed so that even if someone succeeds in cutting the padlock, they cannot turn the lock rods.
  • Container bolts protect the doors of trailers and/or containers against forcible opening and may be placed around the door handles and locked sideways with an integrated lock cylinder.
  • the existing prior art solutions suffer from one or a number of disadvantages.
  • the main disadvantage is that the existing interlocking devices that protect the doors against unauthorised opening generally engage the lock rods.
  • perpetrators have become so sophisticated and well-equipped that they often use power tools to cut the lock rods above and below the locking device, effectively removing a portion of the lock rods and bypassing the locking device entirely.
  • Another method used includes cutting the top and bottom cam of a lock rod, effectively disengaging the lock rod from the container.
  • Another disadvantage is that some locking devices require modifications to the container itself, which is not only a cost factor, but also require skilled labour.
  • a door lock for an intermodal container is described in WO2019064192, which was filed by the same applicant as in this application, and which incorporates an electronic mechanism to actuate a lock between a locked and unlocked condition.
  • This door lock is placed over the external lock rods of the container door and locking the electronic mechanism causes the lock rods and the associated lock rods’ cam keepers to be captured by the door lock, thus making it impossible to disengage the lock rod cams from the cam keepers.
  • the electronic mechanism is actuated by means of a battery powered electric motor, which moves between a locked and unlocked position upon receiving a predetermined electronic signal from an electronic receiver.
  • the battery of the electric motor is recharged through solar panels.
  • the receiver relies on satellite track and GPS equipment to function. Upon receiving a correct electronic signal, the receiver energises the motor to move the locking mechanism between the locked and unlocked positions.
  • the door lock described in WO2019064192 provides significant advantages over the prior art, the applicant has identified a number of shortcomings as it applies to specific territories within which this technology is implemented.
  • the battery relies on solar power to recharge, which means that an adequate amount of sunshine is required to operate the door lock. In countries and/or seasons with low amounts of sunshine, the solar power recharging functionality may be compromised, and the battery may run out, causing difficulties with locking / unlocking the door lock.
  • the battery itself may become worn down due to successive charge- discharge cycles, until it becomes incapable of providing sufficient power to move the locking mechanism between a locked and unlocked position.
  • the receiver is depended on an adequate satellite signal to energise the motor to unlock the door.
  • a heavy-duty door lock adapted for locking a door of an intermodal container, wherein the door includes at least one elongate lock rod which terminates at least at one end thereof in a cam, which is dimensioned releasably to engage a complimentarily configured cam keeper that is secured to the container such that rotation of the lock rod alternately forces the cam into and out of the keeper, the door lock comprising - a first laterally displaceable sliding carriage that is displaceable between a locked position, in which it engages the cam and the cam keeper so as to prevent movement of the cam, and an unlocked position in which it is disengaged from the cam and the cam keeper; actuating means for displacing the sliding carriage between the locked and unlocked positions; and a locking arrangement for locking the actuating means, including - a manual locking arrangement which mechanically engages the actuating means and which is displaceable between a locked position, in which it prevents displacement of the actuating means, and an unlocked position,
  • the door lock also comprises a second laterally displaceable sliding carriage that is displaceable between a locked position, in which it engages the lock rod, and an unlocked position in which it is disengaged from the lock rod.
  • the first and second sliding carriages are displaceable simultaneously by the actuating means between the locked and unlocked positions.
  • the door lock comprises a first set of two laterally displaceable sliding carriages that are displaceable in opposite directions to each other so as alternately to engage and disengage the cams and the cam keepers of two neighbouring lock rods; and a second set of two laterally displaceable sliding carriages that are displaceable in opposite directions to each other so as alternately to engage and disengage two neighbouring lock rods.
  • the door lock may include a housing which is configured to house the first and second sets of sliding carriages, the actuating means and the locking arrangement, the housing comprising a base plate, two opposing side walls extending from opposite sides of the base plate, and two opposing end walls extending from opposite ends of the base plate, with at least one of the end walls including lock rod accommodating profiles which are dimensioned to accommodate the lock rods.
  • the door lock may releasably be secured to two neighbouring doors of an intermodal container as an add-on assembly by being fitted over neighbouring lock rods of the doors from outside of the container such that the cams and cam keepers of neighbouring lock rods, as well as a portion of the rods itself, are encased within the housing.
  • the arrangement may be such that the base plate of the housing covers the cams and the cam keepers of neighbouring lock rods, as well as a portion of the rods itself; the side walls of the housing abut the container doors and door frame such that the cams, cam keepers and a portion of the lock rods are housed between the side walls; one end wall of the housing abuts the door frame; and an opposite end wall of the housing, which includes the rod accommodating profiles, abuts the doors.
  • the first laterally displaceable sliding carriages which are dimensioned to engage the cams and cam keepers, each includes a rear locking plate, which slides in between the cam and the cam keeper; and a front locking plate, which slides in between the cam at the base plate of the housing, thereby effectively trapping the cam between the rear and front locking plates of the first set of sliding carriages, making it impossible for the cam to rotate.
  • the rear locking plate may be profiled to fit over the cam keeper.
  • the second laterally displaceable sliding carriages which are dimensioned to engage the lock rods, each includes a rear locking plate, which slides in between the lock rod and the container door when the sliding carriages are in the locked position, thus preventing removal of the door lock from the lock rods.
  • the actuating means may be a mechanically operable actuating means.
  • the actuating means may include an elongate, threaded, axially displaceable shaft which is connected to the base plate of the housing and which is rotatable to effect axial displacement of the shaft.
  • the threaded shaft may be received at one end thereof in a complimentarily threaded securing sleeve which is secured to the base plate of the housing such that the threaded shaft is axially displaceable relative to the securing sleeve.
  • the threaded shaft may protrude through an end wall of the housing and terminate in a handle for mechanically rotating the shaft.
  • the shaft may be connected to the first and second sets of sliding carriages respectively through a series of intermittent, pivotally inter-connected actuating cams such that back-and-forth rotation of the shaft alternately displaces the first and second sets of sliding carriages between the locked and unlocked positions.
  • the actuating means further may include a displaceable threaded actuating sleeve through which the shaft protrudes, and which is axially displaceable on the shaft such that back-and-forth rotation of the shaft alternately displaces the actuating sleeve up and down the shaft.
  • the actuating means further may include a set of two, first actuating cams that are pivotally connected to the baseplate of the housing at radially opposite positions relative to the shaft.
  • the first actuating cams may be substantially T-shaped cams with one arm of each cam also being pivotally connected to the actuating sleeve on the shaft such that linear displacement of the actuating sleeve up or down the shaft imparts reciprocal rotational motion on the first actuating cams.
  • the first actuating cams are rotatable in opposite directions to each other, such that when one first actuating cam rotates clockwise, the other first actuating cam rotates counter clockwise.
  • each of the two T-shaped first actuating cams may pivotally be connected to each of the second set of sliding carriages respectively, such that rotation of the first actuating cams imparts linear displacement of the second set of sliding carriages between the engaged and disengaged positions.
  • the actuating means further may include two spring-loaded stabiliser arms which are pivotally connected respectively to the remaining arms of each of the T-shaped first actuating cams.
  • Each stabiliser arm may comprise a shaft and a spring-loaded rod which is co-axially displaceable within the shaft, the arrangement being such that rotation of the first actuating cams imparts linear displacement of the rods within the shafts of the stabiliser arms.
  • the stabiliser arms may be spring-loaded to accommodate spatial variations between neighbouring lock rods and their associated respective cams and cam keepers.
  • the actuating means further may include a set of two, second actuating cams that are pivotally connected to the baseplate of the housing.
  • the second actuating cams are also pivotally connected to the free ends of the stabiliser arms such that linear displacement of the stabiliser arms imparts reciprocal rotational motion on the second actuating cams.
  • the second actuating cams are rotatable in opposite directions to each other, such that when one second actuating cam rotates clockwise, the other second actuating cam rotates counter-clockwise.
  • the second actuating cams may pivotally be connected to each of the first set of sliding carriages respectively, such that rotation of the second actuating cams imparts linear displacement of the first set of sliding carriages between the engaged and disengaged positions.
  • the manual locking arrangement may comprise a linear gear which is connected to the shaft; a circular gear which rotatably engages the linear gear; a tapered locking pawl which cooperates with the circular gear; a manually displaceable locking rod for displacing the locking pawl; and a cam locker, the manual locking arrangement being mechanically displaceable between a locked position, in which it prevents the actuating means from displacing the sliding carriages, and an unlocked position, in which it allows the actuating means to displace the sliding carriages.
  • the linear gear of the manual locking arrangement may be connected to the shaft through a second, threaded actuating sleeve through which the shaft protrudes, with the second actuating sleeve being axially aligned with, but displaced from, the first actuating sleeve, such that back-and-forth rotation of the shaft displaces the second actuating sleeve up or down the shaft.
  • the locking pawl may pivotally be secured to the base plate of the housing and may be tapered to be wide at its pivoting end and narrow at its engaging end.
  • the locking pawl may be biased towards the locked position in which it engages the circular gear through a spring, which is secured at one end thereof to the base plate of the housing and at an opposite end thereof to the locking pawl.
  • the locking rod may be orientated substantially parallel to the shaft and may protrude through an end wall of the housing, terminating at its one end in a manually operable handle and at its opposite end in the cam locker.
  • the locking rod may axially be displaceable between a first position where it engages the locking pawl and a second position where it disengages from the locking pawl, the arrangement being such that in the first position the locking rod disengages the locking pawl from the circular gear, releasing the shaft to be rotated; and in the second position release of the locking rod from the locking pawl engages the locking pawl with the circular gear, which prevents the shaft from being rotated.
  • the cam locker may provide an actuating surface at a position where the locking rod and the cam locker connects.
  • the locking pawl may include a second engagement formation located between the locking rod and the base plate and which may substantially abut the actuating surface of the cam locker when the locking rod is in a disengaged position.
  • the locking rod may be displaceable between a resting position, in which the second engagement formation of the locking pawl is biased towards engaging the actuating surface, due to the spring, which biases the first engagement formation to engage with the gear teeth of the circular gear; and an extended position, in which the locking rod causes the actuating surface to push against the second engagement formation, which in turn forces the locking pawl to pivot around its own central axis, disengaging the first engagement formation from the gear teeth of the circular gear. Displacement towards the extended position may overcome the force of bias of the spring, such that the locking arrangement is momentarily unlocked.
  • the shaft may now be rotated to either lock or unlock the door lock.
  • Displacement of the locking rod back towards the resting position may happen under the bias force of the spring.
  • Disengagement of the pawl from the circular gear releases the shaft such that the shaft may be rotated to allow the sliding carriages to engage or disengage their associated respective lock rods, cams, and cam keepers.
  • the cam locker may provide a locking cam accommodating profile which captures the locking cam when the locking rod is in the resting position.
  • the electronic locking arrangement comprises a locking cam for cooperating with the cam locker; an electric motor for actuating the locking cam; and an electronic receiver for actuating the electric motor, the electronic locking arrangement being displaceable between an engaged position in which it engages the manual locking arrangement in the locked position, and a disengaged position, in which it disengages the manual locking arrangement such that the manual locking arrangement is displaceable towards the unlocked position.
  • the locking cam may be connected to the electric motor which turns the locking cam between a locked position, in which the locking cam is trapped in the locking cam accommodating profile of the cam locker, and an unlocked position, in which the locking cam is disengaged from the locking cam accommodating profile.
  • the electric motor may receive electronic communication from a receiver, which in turn may receive an electronic command from a transmitter to signal the motor to actuate the locking cam between the engaged and disengaged positions.
  • the receiver may be connected to the motor via electric cables.
  • the receiver may be secured to the base plate of the housing.

  • the locking rod [84] terminates in a handle [96] at its one end, which extends beyond the housing [24] through wall [30], such that the handle [96] is used to displace the locking rod [84] between an extended position, where it engages the locking pawl [86], and a resting position, where it disengages from the locking pawl [86].
  • Engagement of the locking pawl [86] by the locking rod [84] disengages the locking pawl [86] from the circular gear [80], and disengagement of the locking pawl [86] by the locking rod [84] engages the locking pawl [86] with the circular gear [80].
  • Disengagement of the locking pawl [86] from the circular gear [80] releases the shaft [40] such that the shaft [40] may be rotated to allow the sliding carriages [18, 20] to engage or disengage their associated respective lock rods [12], cams [14] and cam keepers [16].
  • the locking rod [84] is connected to the cam locker [98].
  • the cam locker [98] provides an actuating surface [100] where the locking rod [84] and the cam locker [98] connects.
  • a second engagement formation [97] of the locking pawl [86] is positioned between the locking rod [84] and the base plate [26] and abuts actuating surface [100] of cam locker [98] when the locking rod [84] is in the resting position.
  • the locking rod [84] is normally in the resting position, wherein the second engagement formation [97] of the locking pawl [86] is biased towards abutting the actuating surface [100], due to spring [92], which biases the first engagement formation [90] to engage with gear teeth [82]
  • the locking rod [84] is displaced towards the extended position, as shown in Figure 4, the locking rod [84] causes actuating surface [100] to push against the second engagement formation [97], which in turn forces pawl [86] to pivot around bolt [88] and which disengages engagement formation [90] from gear teeth [82]
  • the displacement towards the extended position overcomes the force of bias of spring [92], such that the locking arrangement [72] is momentarily unlocked.
  • the shaft [40] can now be rotated to either lock (as shown in Figure 1) or unlock (as shown in Figure 5) the door lock [10]. Displacement of the locking rod [84] back towards the resting position happens under the force of bias of spring [92] Before the manual locking arrangement [74, 80, 86, 84, 98] can be unlocked to allow rotation of the shaft [40] and disengagement of the sliding carriages [18, 20] from their associated respective lock rods [12], cams [14] and cam keepers [16], the electronic locking arrangement [104, 106, 112] must first be unlocked.
  • the electronic locking arrangement [104, 106, 112] includes the locking cam [104], the electric motor [106] and the electronic receiver [112] with a protective cap [114] which covers the receiver [112] where the receiver [112] protrudes beyond the housing [24]
  • the cam locker [98], which forms part of the manual locking arrangement [74, 80, 86, 84, 98], further provides a cam accommodating profile [102] which, when the locking rod [84] is in the resting position, is capable of receiving the locking cam [104], wherein the cam accommodating profile [102] is complimentarily dimensioned to capture the locking cam [104] therein.
  • the locking cam [104] is connected to the electric motor [106] which turns the locking cam [104] between a locked position, as shown in Figure 3, wherein a rounded surface [108] of the locking cam [104] is operatively engaged by the cam accommodating profile [102]; and an unlocked position, as shown in Figure 4, wherein a flat surface [110] of the locking cam [104] is orientated towards the cam accommodating profile [102], thereby causing the locking cam [104] to disengage from the cam accommodating profile [102] of the cam locker [98].
  • the locking cam [104] Once the locking cam [104] has been disengaged from the cam locker [98], the locking rod [84] is free to be displaced from the resting position to the extended position, as shown in Figure 4. After the locking rod [84] is displaced back to the resting position, the locking cam [104] must be rotated such that the circular surface [108] of the locking cam [104] is once again engaged by the cam accommodating profile [102] of the cam locker [98], as shown in Figure 3.
  • the electric motor [106] which actuates the cam [104] between the engaged and disengaged positions, receives electronic communication from a receiver [112].
  • the receiver [112] receives an electronic command from a transmitter (not shown) to signal the motor [106] to actuate the cam [104] between the engaged and disengaged positions.
  • the receiver [112] is connected to the motor [106] via electric cables (not shown).
  • the receiver [112] is secured to the base plate [26] of the housing [24]
  • the cap [114] must be removed before the receiver [112] will pick up the electronic signal sent by the transmitter.
  • the receiver [112] may be selected from a group of receivers capable of receiving electronic signals from a digital key, an NFC-enabled iOS or Android mobile phone key, a fob, a tag or a PIN code.
