Description

CARGO SECURITY DEVICESCROSS-REFERENCE TO RELATED APPLICATIONS

[0001] The present application claims priority to U.S. Provisional Patent Application Serial No.63 / 720,176, filed November 13, 2024, and titled “SYSTEMS AND METHODS FOR SECURING A TRAILER,” U.S. Provisional Patent Application Serial No. 63 / 725,533, filed November 26, 2024, and titled “SYSTEMS AND METHODS FOR SECURING PNEUMATIC GLADHANDS,” U.S. Provisional Patent Application Serial No. 63 / 725,537, filed November 26, 2024, and titled “SYSTEMS AND METHODS FOR SECURING THE LANDING GEAR OF A TRAILER,” and U.S. Provisional Patent Application Serial No. 63 / 725,860, filed November 27, 2024, and titled “SYSTEMS AND METHODS FOR SECURING A CARGO CONTAINER DOOR,” the entire disclosures of which are hereby expressly incorporated by reference herein.BACKGROUND

[0002] In examples, a cargo-carrying container includes one or more features that may be access-controlled to immobilize the cargo-carrying container and / or deter theft or unauthorized usage of the cargo-carrying container. For example, a cargo-carrying container may be configured with one or more doors that facilitate access to an interior, for example for loading and unloading of cargo and / or securing the interior cargo area. As another example, landing gear may be extended to support a portion of a cargo-carrying container when parked. Accordingly, when connected to a tractor / truck or other vehicle, the landing gears are retracted for transport of the cargo-carrying container. As a further example, a cargo-carrying container may lack a means for propulsion and may instead rely on another vehicle for locomotion. One common configuration of a trailer-vehicle combination is a trailer with a kingpin utilized to engage a fifth wheel of a vehicle. Finally, gladhands may be used to connect one or more pneumatic lines of a cargo-carrying container to a tractor / truck or other vehicle for the tractor to provide compressed air to the cargo-carrying container for use with its braking system and / or other pneumatic components (e.g., suspension, tire inflation, etc ).

[0003] Thus, restricting access to and / or use of one or more such features may thus limit mobility and / or utility of the cargo-carrying container, thereby deterring theft (e.g., of cargo within the cargo-carrying container and / or of the cargo-carrying container itself).

[0004] It is with respect to these and other general considerations that embodiments have been described. Also, although relatively specific problems have been discussed, it should be understood that the embodiments should not be limited to solving the specific problems identified in the background.SUMMARY

[0005] In one aspect, a door lock for a cargo-carrying container is provided. The door lock comprises: a housing; a hollow member extending from the housing, the hollow member sized and shaped to receive a pin therethrough; a flag coupled to the pin within the housing, thereby forming a locking assembly, wherein the housing includes an aperture through which the flag extends; and a linear actuator coupled to the locking assembly, wherein the linear actuator is configured to actuate the locking assembly along an axis.

[0006] In another aspect, a kingpin lock for a cargo-carrying container is provided. The kingpin lock comprises: a locking portion sized and shaped to at least partially shield a kingpin of the cargo-carrying container when in a locked position, wherein the locking portion prevents interfacing between the kingpin and a fifth wheel of a tractor in the locked position; and a linear motion element coupled to the locking portion of the kingpin lock, the linear motion element configured to move the locking portion between an unlocked position and the locked position.

[0007] In a further aspect, a cargo-carrying container is provided. The cargo-carrying container comprises: a floor; a plurality of walls extending upward from the floor along a vertical axis, thereby defining a cargo space therebetween; a first door and a second door each rotatably coupled to a wall of the plurality of walls; a catch plate coupled to the first door; and a door lock coupled to the second door. The door lock comprises: a housing; a hollow member extending from the housing, the hollow member sized and shaped to receive a pin therethrough; a flag coupled to the pin within the housing, thereby forming a locking assembly, wherein the housing includes an aperture through which the flag extends; and a linear actuator coupled to the locking assembly, wherein the linear actuator is configured to actuate the locking assembly along the vertical axis.

[0034] In the following detailed description, references are made to the accompanying drawings that form a part hereof, and in which are shown by way of illustrations specific embodiments or examples. These aspects may be combined, other aspects may be utilized, and structural changes may be made without departing from the present disclosure. Embodiments may be practiced as methods, systems or devices. The following detailed description is therefore not to be taken in a limiting sense, and the scope of the present disclosure is defined by the appended claims and their equivalents.

[0035] Fig. 1 illustrates a conceptual overview 100 of an example cargo-carrying container 104 according to aspects described herein. As illustrated, Fig. 1 includes tractor 102, cargo-carrying container 104, and remote computing device 106.

[0036] Cargo-carrying container 104 (also referred to herein as a “trailer”) may be any of a variety of cargo-carrying containers, including, but not limited to, a dry van, a refrigerated van, a box truck, a closed trailer, an open trailer (e.g., a flatbed, “low boy,” or a chassis), a shipping container, and / or a mounted box, among other examples. Thus, it will be appreciated that cargo-carrying container 104 may or may not be temperature controlled. As a further option, embodiments may apply to an open trailer, which is utilized to transport cargo comprising one or more intermodal shipping containers.

[0037] As illustrated, cargo-carrying container 104 includes gladhand 118, landing gear 120, kingpin 122, and door 124. While cargo-carrying container 104 is illustrated as including one of each such features, it will be appreciated that, in other examples, additional or fewer such features may be included. For example, cargo-carrying container 104 may be a van, thereby omitting landing gear 120, gladhand 118, and kingpin 122. As another example, cargo-carrying container 104 is a trailer, such that gladhand 118, landing gear 120, and kingpin 122 are each included accordingly. As a further example, cargo-carrying container 104 may be an open trailer, such that door 124 is omitted or is instead a gate, among other examples. Example aspects of gladhand 118, landing gear 120, kingpin 122, and door 124 are discussed below with respect to Figs. 14-19, Figs.8-13, Figs. 20A-24B, and Figs. 2-7C, respectively, and are therefore not necessarily redescribed in detail with respect to Fig. 1.

[0038] Fig. 1 includes a dashed box surrounding gladhand 118, landing gear 120, kingpin 122, and door 124 to indicate that one or more such features may be secured using locking device(s) 108. In examples, a single locking device is associated with multiple features of cargo-carrying container 104, thereby contemporaneously locking / unlocking a plurality of features of cargocarrying container 104 according to aspects described herein. In other examples, one or more features each has a corresponding locking device 108, which may thus be individually actuatable according to aspects of the present disclosure. It will therefore be appreciated that any of a variety of locking devices may be used. Example locking devices are described in more detail below with reference to Figs. 2-24B. As a result of restricting one or more of features 118, 120, 122, and / or124, theft of the cargo-carrying container and / or cargo therein may be deterred according to aspects of the present disclosure.

[0039] Cargo-carrying container 104 includes controller 126, which may control locking device(s) 108. In examples, locking device(s) 108 are electronically, pneumatically, and / or hydraulically actuatable (e.g., linearly and / or rotatable actuatable), such that controller 126 actuates locking device(s) 108 accordingly, for example to lock or unlock a given locking device accordingly. In examples, cargo-carrying container 104 includes an electrical source, a pneumatic source, and / or a hydraulic source for actuating locking device(s) 108 accordingly, though, in the depicted example, tractor 102 includes electrical source 112 and pneumatic source 114 (e.g., which cargocarrying container 104 may thus couple thereto, in examples). Thus, it will be appreciated that tractor 102 and / or cargo-carrying container 104 may include one or more such sources. While example sources are described, it will be appreciated that additional or alternative sources may be used or, in other examples, one or more such sources may be omitted.

[0040] According to the examples noted above, cargo-carrying container 104 may provide its own propulsion (e.g., such that cargo-carrying container 104 may include a prime mover, such as prime mover 110) or may be instead moved by a vehicle (e.g., tractor 102). Thus, tractor 102 is illustrated using a dashed box to indicate that, in some examples, such aspects may be omitted. Examples of tractor 102 include, but are not limited to, a semi-truck or a semi-tractor, among other examples.

[0041] As illustrated, tractor 102 includes prime mover 110, electrical source 112, pneumatic source 114, and controller 116. In examples, electrical source 112 and / or pneumatic source 114 provide electricity and / or air, respectively, for use by tractor 102 and / or by cargo-carrying container 104. For instance, a pneumatic connection between tractor 102 and cargo-carrying container 104 may be established by gladhand 118 according to aspects described herein.

[0042] Tractor 102 is further illustrated as comprising controller 116, which may communicate with controller 126 and / or directly actuate locking device(s) 108, among other examples. It will therefore be appreciated that control of locking device(s) 108 may be local to cargo-carrying container 104 (e.g., by controller 126) and / or remote (e g., by application 128, via controller 126). Arrow 130 is included to illustrate such communication, which may be wired (e.g., via a controller area network (CAN) bus or Ethernet) and / or wireless (e.g., via Bluetooth Low Energy and / or WiFi), among other examples.

[0043] System 100 is further illustrated as including remote computing device 106. Remote computing device 106 is illustrated using a dashed box to indicate that, in some examples, remote computing device 106 may be omitted. As illustrated, remote computing device 106 includes application 128, which may be operative to control locking device(s) 108. Thus, remote computing device 106 may communicate with tractor 102 (e.g., as illustrated by arrow 132) and / or cargocarrying container 104 (e.g., as illustrated by arrow 134) to lock and / or unlock locking device(s) 108. Similar to the above-discussed communication between tractor 102 and cargo-carrying container 104, communication by remote computing device 106 may be wired and / or wireless. While example locking devices are described herein with respect to controller-based actuation, it will be appreciated that, in other examples, the disclosed aspects may additionally, or alternatively, be manually actuatable.

[0044] Example Door Locks

[0045] In order to deter or prevent unauthorized access to the cargo area, and thereby deter or prevent theft of the cargo, the one or more lockable doors may be used. For multi-door structures, generally a first door is secured with a lockable structure while a second door is absent a lockable structure but is mechanically limited, such as with a flange, to be unopenable unless the first door is open.

[0046] Example door locks described herein are generally directed to a lock and associated linkage on one or more interior surfaces of a cargo-carrying container. In examples, the interior of a cargocarrying container offers additional protection to the lock and linkage from attack by a potential thief as well as from the elements. However, in other embodiments, some or all of a lock and linkage may be disposed on the exterior of a cargo-carrying container. For example, a cargocarrying container may be configured to haul unpackaged bulk materials (e.g., wood chips, scrap metal, etc.) that may interfere with the operation of the lock or associated linkage if disposed on an interior surface. In examples, an electronically actuated door lock is used, where at least one door will remain locked until a signal is received (e.g., from a controller) to unlock the doors. As noted above, power may be obtained from a tractor (e.g., tractor 102 in Fig. 1) and / or from an onboard rechargeable battery. In some examples, the on-board battery may be recharged when coupled with the tractor.

[0047] Fig. 2 illustrates an example of a door lock 200 in accordance with aspects of the present disclosure. In one embodiment, door lock 200 comprises rotary actuator 202 that providesrotational movement to linkage 204, which is pivotally attached thereto. Rotary actuator 202 may utilize electrical or pneumatic power, such as from trailer 216, and may be triggered by a control unit (not shown).

[0048] Door lock 200 may be disposed in housing 206 or a similar protective and / or supportive structure, such as to mount to door 210 of trailer 216 (e.g., aspects of which may be similar to those discussed above with respect to cargo-carrying container 104 of Fig. 1). Operation of rotary actuator 202 selectively maintains slider 208 in a locked or unlocked position and transitions therebetween. In an unlocked position, rotary actuator 202A is rotated to be in a first position and operate linkage 204A to retract slider 208. As a result, slider 208 disengages bracket 218 or another latching component and door 210 is unlocked. In a locked position, rotary actuator 202B is rotated to be in a second position and operate linkage 204B to extend slider 208. As a result, slider 208 engages with bracket 218 and / or another latching component, and door 210 is locked.

[0049] Trailer 216 is illustrated as trailer 216A (top view) and trailer 216B (elevation view) and comprises door 210 and door 212. One or more bars 214 may be utilized to prevent door 212 from opening until door 210 is unlocked and opened. Door 212 is locked via a mechanical linkage (e.g., a flange) that requires door 210 to be open. Bracket 218, as illustrated and in one embodiment, comprises a pair of brackets 218, each engaging a pair of sliders 208. In another embodiment, a single bracket 218 is utilized to engage a single slider 208. Bracket 218 may be a single bracket 218, such as in one of the floor or roof of trailer 218. Additionally, or alternatively, sliders 208 may be deployed to engage in one or more brackets 218 disposed on / in the side of trailer 216. Bracket 218 may be embodied as a latching component affixed to the floor, roof, and / or other surface of trailer 218 or embodied as a recess within the floor, roof, and / or other surface of trailer 218.

[0050] Fig. 3 illustrates an example of another door lock 300 in accordance with aspects of the present disclosure. Insert 302 illustrates one embodiment of door lock 300 comprising rotary actuator 304, which comprises a pinion gear that engages with rack 306. Rotary actuator 304 is operated by electrical or pneumatic power, such as from trailer 308 (e g., aspects of which may be similar to those discussed above with respect to cargo-carrying container 104 of Fig. 1), which is triggered by a control unit (not shown).

[0051] Rotary actuator 304 rotates to cause rack 306 to selectively extend, retract, or be maintained in a current position. When rotary actuator 304 is rotated to a first position, rack 306 extends toengage with bracket 310. Rack 306 may be slidably housed in housing 316. As a result, door 312 is locked by door lock 300. Door 314 is locked via a mechanical linkage (e.g., a flange) that requires door 312 to be open. When rotary actuator 304 is rotated to a second position, rack 306 is retracted and disengaged from bracket 310. As a result, door 312 is unlocked by door lock 300.

[0052] In one embodiment, and as illustrated, rotary actuator 304 engages with two racks 306, each of which engages respective brackets 310. In another embodiment, only one rack 306 and one bracket 310 are utilized. Additional racks 306 and brackets 310 may be utilized, such as in the side of trailer 308.

[0053] Fig. 4 illustrates an example of another door lock 400 in accordance with aspects of the present disclosure. Door lock 400 comprises a rotary actuator 412 mounted inside the bottom of door 404. Rotary actuator 412 is operated by electrical or pneumatic power, such as from trailer 402 (e.g., aspects of which may be similar to those discussed above with respect to cargo-carrying container 104 of Fig. 1), which is triggered by a control unit (not shown). In another embodiment, rotary actuator 412 comprises a solenoid.

[0054] Locked door 404A is locked by door lock 400A by rotary actuator 412 rotating hook 414 to engage latching component 416. In one embodiment, door lock 400A and hook 414 are attached to door 404 and hook 414 engages latching component 416 integrated into floor 410 of trailer 402. In another embodiment, door lock 400 A causes hook 414 to engage latching component 416 integrated into a side wall of trailer 402 (not shown). In another embodiment, latching component 416 is integrated into door 404 and door lock 400 attached to, or integrated into, the floor and / or side wall of trailer 402 (not shown).

[0055] In one embodiment, door lock 400A is operated in a first position to engage a pin, lip, flange, etc. of latching component 416 to maintain door 404A as locked. In another embodiment, door lock 400B is operated into a second position to disengage latching component 416 and unlock door 404B. It should be appreciated that, while two of door locks 400 are illustrated, in other embodiments, more than or fewer than two door locks 400 and corresponding latching components 416 are utilized.

[0056] Figs. 5A-4C illustrate an example of another door lock 500 in accordance with aspects of the present disclosure. In one embodiment, lock 500 comprises actuator 502 to operate pin 504 and selectively engage recess 506 or a bracket. Actuator 502 may be embodied, in whole or in part, as a solenoid or linear actuator, which may be operated by electrical or pneumatic power (e.g.,such as from trailer 508, which may be similar to cargo-carrying container 104 of Fig. 1), among other examples, which may thus be controlled by a control unit (not shown).

[0057] In one embodiment, lock 500 is installed on the inside of door 510 of trailer 508, and pin 504 selectively engages recess 506 in or on the sidewall of trailer 508. In another embodiment, lock 500 is installed in or on the sidewall of trailer 508, and pin 504 selectively engages recess 506 in or on door 510. It should be appreciated that one or more of lock 500, and corresponding recess 506, may be implemented to selectively lock door 510. Fig. 5B illustrates lock 500 and recess 506 in a first, lower, portion of door 510.

[0058] When lock 500 is in a first position, pin 504 of lock 500 engages recess 506 to maintain door 510A in a locked configuration, such as when door 510 is a rolling door. When lock 500 is operated in a second position, pin 504 of lock 500 disengages recess 506 to maintain door 510B in an unlocked configuration. Fig. 4C illustrates lock 500 and recess 506 in a second, higher, portion of door 510. It will therefore be appreciated that any number of locks 500 may be used, at any of a variety of locations.

[0059] Figs. 6A and 6B illustrate an example of another door lock 600 in accordance with aspects of the present disclosure. In one embodiment, lock 600 comprises pin 608 to selectively engage recess 604 or, alternatively, a bracket. Lock 600 may be embodied, in whole or in part, as a solenoid or linear actuator, which may thus be operated using electrical or pneumatic power (e.g., from trailer 602), which is controlled by a control unit (not shown). In examples, it may be preferable, but not required, for lock 600 to engage recess 604 located near the top of door 606, for example to avoid interfering with loading and unloading of cargo in the trailer 602 (e.g., aspects of which may be similar to those discussed above with respect to cargo-carrying container 104 of Fig- I)-

[0060] When lock 600 is in a first position, pin 608 of lock 600 engages recess 604 to maintain door 606A in a locked configuration, such as when door 606 is a rolling door. When lock 600 is operated in a second position, pin 608 of lock 600 disengages recess 604 to maintain door 606B in an unlocked configuration.

[0061] Figs. 7A-7C illustrate an example of another door lock 700 in accordance with aspects of the present disclosure. As illustrated, door lock 700 is coupled to door 712 of cargo-carrying container 710 (e.g., aspects of which may be similar to those discussed above with respect to cargocarrying container 104 of Fig. 1). In examples, cargo-carrying container 710 includes a floor anda plurality of walls extending upward from the floor. Tn some instances, cargo-carrying container 710 includes a roof or may be an open cargo-carrying container, among other examples. Doors 712 and 714 may each be rotatably coupled to a respective wall (e.g., by one or more hinges). Thus, when unlocked, doors 712 and 714 may each rotate about a vertical axis.

[0062] It will be appreciated that door lock 700 may be coupled to an inside portion of door 712 or an outside portion of door 712. Thus, flag 702 may engage with catch plate 706 (e.g., which is coupled to or formed within door 714) on the inside or on the outside of trailer 710 accordingly. When locked, catch plate 706 may contact flag 702 and / or may restrict movement of flag 702, among other examples. Similarly, pin 704B (Figs. 7B and 7C), which is disposed within hollow member 704 A, may engage with aperture 708 (e.g., which may be formed in a floor of trailer 710 or may comprise a feature affixed thereto) on the interior or at the exterior of trailer 710. Thus, door lock 700 is a two-point lock that engages with both catch plate 706 and aperture 708 to secure doors 712 and 714. While Fig. 7A is depicted in an example where door lock 700 engages with another door (e.g., door 714), it will be appreciated that similar aspects may be used to secure a single door (e.g., where catch plate 706 is instead affixed to a wall of cargo-carrying container 710) and / or a gate (e.g., that rotates about a lateral axis instead of about a vertical axis) or roll door.

[0063] Fig. 7A depicts an example in which door lock 700 is in an unlocked position, whereas Fig.7B depicts an example in which door lock 700 is in a locked position. As illustrated in Fig. 7B, flag 702 and pin 704B have moved downward (e.g., as illustrated by arrow 720), thereby engaging with catch plate 706 of door 714 and aperture 708, respectively. It will be appreciated that, in other configurations, flag 702 and pin 704B may move in any of a variety of other directions. For example, flag 702 and pin 704B may move upward (e.g., in an instance where pin 704B instead engages with an aperture of a roof of cargo-carrying container 710) or laterally (e.g., in an instance where door lock 700 locks a gate, among other examples.

[0064] Fig. 7C depicts an exposed perspective view of door lock 700 (e.g., where a cover of door lock 700 has been removed). As illustrated, flag 702 and pin 704B are coupled together within housing 701, thereby forming a locking assembly that is actuated (e.g., vertically, as illustrated by arrow 720) by linear actuator 716. Hollow member 704A extends downward (see Figs. 7A and 7B) from housing 701, thereby shielding pin 704B as it extends from housing 701 to engage with an aperture (e.g., aperture 708 in Figs. 7A and 7B). Housing 701 further comprises an aperture 703through which flag 702 extends. As illustrated, aperture 703 is sized and shaped to permit movement of flag 702 along vertical axis 720.

[0065] Door lock 700 further comprises compliant mechanism 718 (e.g., including a spring), thereby providing a two-stage mechanism with which flag 702 and pin 704B are actuated. In examples, compliant mechanism 718 drives flag 702 and pin 704B a first distance and linear actuator 716 drives flag 702 and pin 704B a second distance. In the depicted example, linear actuator 716 comprises an electric motor. It will be appreciated that additional or alternative actuators and / or compliant mechanisms may be used. Additionally, in other examples, compliant mechanism 718 or linear actuator 716 may be omitted, thereby providing a door lock that includes only a single travel stage.

[0066] Example Landing Gear Locks

[0067] In examples, a tractor (e g., tractor 102 in Fig. 1) provides support when a cargo-carrying container (e.g., cargo-carrying container 104) is coupled with the trailer, such as via a kingpin that is retained in the lockjaw of the tractor's fifth wheel. In such examples, legs of the landing gear of the cargo-carrying container may be minimally raised or may still be in contact with the ground. As a result, failure to retract the landing gear may thus effectively immobilize the cargo-carrying container, since operating / moving the cargo-carrying container with the landing gear extended may cause the landing gear to strike or continually remain in contact with the roadway. Such contact with the ground may negatively affect control and / or may be readily apparent by others, including law enforcement, due to the noise and sparks from the landing gear scraping the roadway. As a result, an attempt to steal a cargo-carrying container may be deterred or prevented if an unauthorized party were prevented from retracting the landing gear. Similarly, a cargocarrying container attached to a tractor would be difficult to detach, and very difficult to reattach, if the landing gear remained retracted. Additionally, a detached cargo-carrying container resting on raised landing gear would be pitched at an angle that would be readily recognized as an abnormality by others.

[0068] According to aspects described herein, a remotely actuated locking device is provided to selectively allow or prevent operation of landing gear, for example thereby permitting landing gear retraction to enable usage of the cargo-carrying container or denying landing gear retraction to disable usage of the cargo-carrying container. In examples, the lock is electrically powered by an internal battery and / or a connection to an external power source (e.g., of a tractor). Power and / oroperation signals may be provided by circuitry and communication components within the locking device and / or via signals from a controller in communication with the lock (e.g., of a cargocarrying container and / or of a tractor). In another embodiment, the locking device comprises a pneumatically powered actuator powered by compressed air, such as via a connection to an air line of a tractor.

[0069] Fig. 8 illustrates an example landing gear lock 800 in accordance with aspects of the present disclosure. Landing gear lock 800, when affixed to trailer 816 (e.g., on a portion of outer housing 808 of the landing gear structure), selectively prevents leg 806 from retracting into outer housing 808. In examples, aspects of trailer 816 are similar to those discussed above with respect to cargocarrying container 104 of Fig. 1.

[0070] In one embodiment, landing gear lock 800 comprises actuator 802 to extend and retract pin 804. In one embodiment, actuator 802 comprises a solenoid. In another embodiment, actuator 802 comprises a linear actuator. When landing gear lock 800 is locked, a rotational force applied to crankshaft 810, such as by handle 812, would be resisted by pin 804 engaging opening 814 of leg 806 and, additionally or alternatively, engaging opening 814.

[0071] In one embodiment, actuator 802 extends pin 804A into a first position to engage opening 814 and thereby prevent leg 806 from retracting. In another embodiment, actuator 802 retracts pin 804B into a second position to disengage opening 814, thereby permitting leg 806 to be retracted. Additionally, or alternatively, actuator 802 extends pin 804A into a first position to engage opening 814, thereby preventing leg 806 from being extended. As another example, actuator 802 retracts pin 804B into the second position to disengage opening 814, thereby enabling leg 806 to be extended.

[0072] Landing gear lock 800 may be operated in the first (locked) position when power is applied and in a second (unlocked) position with no power applied or, alternatively, operated in the first (locked) position with no power applied and in a second (unlocked) position when power is applied.

[0073] Fig. 9 illustrates an example of another landing gear lock 900 in accordance with aspects of the present disclosure. Landing gear lock 900, when affixed to trailer 816, selectively prevents leg 806 from retracting into outer housing 808 and / or extending therefrom.

[0074] In one embodiment, landing gear lock 900 comprises actuator 902 to extend and retract pin 904. In one embodiment, actuator 902 comprises a solenoid. In another embodiment, actuator 902comprises a linear actuator. When landing gear lock 900 is locked, a rotational force applied to crankshaft 810, such as by handle 812, would be resisted by face gear 906 A engaging fixed element 908. In the depicted example, face gear 906A is not mechanically tied to crankshaft 810, except when engaged with fixed element 908, with fixed element 908 being fixed to crankshaft 810.

[0075] In one embodiment, actuator 902 extends pin 904A into a first position to press face gear 906A into fixed element 908 and thereby prevent crankshaft 810 from rotating and, in turn, preventing leg 806 from retracting and / or extending. In another embodiment, actuator 902 retracts pin 904B into a second position to disengage face gear 906B from fixed element 908 and thereby allow crankshaft 810 to rotate and leg 806 to be retracted and / or extended.

[0076] Landing gear lock 900 may thus be operated in the first (locked) position when power is applied and in a second (unlocked) position with no power applied or, alternatively, operated in the first (locked) position with no power applied and in a second (unlocked) position when power is applied.

[0077] Fig. 10 illustrates landing gear lock 1000 in accordance with aspects of the present disclosure. Landing gear lock 1000, when affixed to trailer 816, selectively prevents leg 806 from retracting into outer housing 808 and / or extending therefrom.

[0078] In one embodiment, landing gear lock 1000 comprises actuator 1002 to extend and retract pin 1004. In one embodiment, actuator 1002 comprises a solenoid. In another embodiment, actuator 1002 comprises a linear actuator. When landing gear lock 1000 is locked, a rotational force applied to crankshaft 810, such as by handle 812, would be resisted by linkage 1008B being extended away from crankshaft 810 and engaging with the undercarriage of trailer 816.

[0079] In one embodiment, actuator 1002 extends pin 1004B into a first position, placing translating lock 1006B in a first, closer, position towards fixed element 1010 and thereby extending linkage 1008B. In another embodiment, actuator 1002 retracts pin 1004A into a second position, placing translating lock 1006A in a second, farther position from fixed element 1010 and thereby retracting linkage 1008A. As a result, leg 806 extends or retracts solely when operated by landing gear lock 1000.

[0080] Fig. 11 illustrates an example of another landing gear lock 1100 in accordance with aspects of the present disclosure. In one embodiment, a handle, such as handle 812, is omitted, such that the sole means of applying a rotational force to crankshaft 810 is provided by motor 1102 oflanding gear lock 1100.

[0082] In one embodiment, landing gear lock 1200 comprises actuator 1202 to extend and retract pin 1204. In one embodiment, actuator 1202 comprises a solenoid. In another embodiment, actuator 1202 comprises a linear actuator. When landing gear lock 1200 is locked, pin 1204 A is extended to retain handle 812, which is mechanically linked to crankshaft 810, which in turn operates leg 806.

[0083] In one embodiment, actuator 1202 extends pin 1204 A into a first position to retain handle 812 and thereby prevent leg 806 from retracting. In another embodiment, actuator 1202 retracts pin 1204B into a second position to release handle 812 and thereby permit leg 806 to be retracted.

[0084] Landing gear 1200 may be operated in the first (locked) position when power is applied and in a second (unlocked) position with no power applied or, alternatively, operated in the first (locked) position with no power applied and in a second (unlocked) position when power is applied.

[0085] Fig. 13 illustrates an example of another landing gear lock 1300 in accordance with aspects of the present disclosure. Landing gear lock 1300, when affixed to trailer 816, such as on a portion of the landing gear structure, selectively prevents leg 806 from retracting into outer housing 808.

[0086] In one embodiment, landing gear lock 1300 comprises actuator 1302 to extend and retract pin 1304. In one embodiment, actuator 1302 comprises a solenoid. In another embodiment, actuator 1302 comprises a linear actuator. When landing gear lock 1300 is locked, pin 1304A is extended to engage a tool of gear 1308 fixed to crankshaft 810. As a result, landing gear lock 1300, when locked, prevents leg 806 from being extended or retracted.

[0087] In one embodiment, actuator 1302 extends pin 1304A into a first position to engage gear 1308 and thereby preventing crankshaft 810 from rotating and, in turn, preventing leg 806 from retracting or extending. In another embodiment, actuator 1302 retracts pin 1304B into a second position to disengage gear 1308 and thereby allow crankshaft 810 to rotate and, in turn, allowing leg 806 to be retracted or extended.

[0088] Landing gear lock 1300 may be operated in the first (locked) position when power is applied and in a second (unlocked) position with no power applied or, alternatively, operated in the first (locked) position with no power applied and in a second (unlocked) position when power is applied.

[0103] Example Kingpin Locks

[0104] In examples, a kingpin of a cargo-carrying container (e.g., cargo-carrying container 104 in Fig. 1) engages a fifth wheel of a vehicle (e.g., a tractor, such as tractor 102). Once engaged, the vehicle provides locomotion to the trailer via the mechanical linkage between the fifth wheel and the kingpin. Typically, the fifth wheel-kingpin linkage allows the cargo-carrying container to pivot and / or supports a portion of the cargo-carrying container. Thus, in some examples, theft of a trailer and / or cargo therein, may entail the attachment of an unauthorized vehicle, via the kingpin, to a fifth wheel of the vehicle. Accordingly, deterring or preventing the unauthorized engagement of a kingpin of a cargo-carrying container may deter or prevent the theft of the trailer and / or the trailer’ s cargo.

[0105] According to aspects disclosed herein, mechanical shielding may be provided to selectively shield a kingpin and, as a result, prevent or deter engagement of the kingpin by an unauthorized vehicle. The disclosed aspects may selectively allow engagement of the kingpin, such as by a fifth wheel of a vehicle associated with an authorized user. In examples, a fifth wheel of a tractor engages a kingpin via the top plate. The top plate has a lock jaw or other locking mechanism in approximately the center of the top plate to retain the kingpin until released. The top plate may comprise a V-shaped opening to facilitate engagement with a kingpin, such as by backing a truck towards the trailer, to allow the moving vehicle to direct the kingpin, via the V-shaped opening, into the locking position.

[0106] In accordance with the disclosed aspects, the shielding, when in a locked position, may prevent unauthorized access by engaging the top plate of the fifth wheel and, in doing so, thereby preventing the kingpin from engaging with the fifth wheel. Such a shield may be held in place by an actuator and / or other component to resist the top plate. Thus, an attempt to attach anunauthorized vehicle to the cargo-carrying container may stop the vehicle or may cause the vehicle to push the entire cargo-carrying container, such that the kingpin of the cargo-carrying container remains away from the fifth wheel. Additionally, or alternatively, a shield according to aspects described herein may be sized and / or shaped to block the fifth wheel (e.g., the fifth wheel’s lock jaw) vertically, thereby preventing the kingpin from being lowered directly into the lockjaw from above or the lockjaw from being raised directly onto the kingpin from below.

[0107] In other examples, a shield according to aspects described herein may be mechanically linked to an actuator (e.g., a hydraulic motor, a pneumatic motor, an electrical motor, a linear motor, a solenoid, a spring, etc.) to selectively extend (or otherwise lock) and retract (or otherwise unlock) the shield. Thus, when retracted, a vehicle’s fifth wheel may freely approach the kingpin, such that the kingpin may engage the lockjaw and be retained therein. As a result, authorized attachment of the vehicle to the cargo-carrying container may be unencumbered by the shield.

[0108] Figs. 20A-20D illustrate kingpin lock 2000 in accordance with aspects of the present disclosure. Fig. 20A illustrates kingpin lock 2000 as viewed from the underside of a trailer (e.g., aspects of which may be similar to those discussed above with respect to cargo-carrying container 104 of Fig. 1). Fig. 20B illustrates an elevation view of a semi -tractor-trailer comprising kingpin lock 2000. Fig. 20C illustrates a top view of kingpin lock 2000 in a first (locked) position. Fig.20D illustrates a top view of kingpin lock 2000 in a second (unlocked) position.

[0109] In one embodiment, kingpin lock 2000 allows kingpin 2004 to engage fifth wheel 2006 when in the second position (see Fig. 20A and Fig. 20D). Actuator 2002 may be electrically, hydraulically, or pneumatically operated to extend kingpin lock 2000 to place kingpin lock 2000 in the first position and shield kingpin 2004 from engagement by fifth wheel 2006 (see Fig. 20C). The operation of actuator 2002 to maintain the first position and / or the second position or transition therebetween may be provided by energy source 2010 (e.g., battery, generator / alternator, pump, reservoir, retained spring, etc.). Kingpin lock 2000, when in the first position (see Fig. 20C) shields kingpin 2004 from engagement by fifth wheel 2006. Actuator 2002 may be operated to retract kingpin lock 2000 to the second position to allow kingpin 2004 to engage with fifth wheel 2006. The operation of actuator 2002 may be controlled by an access control component 2008.

[0110] Figs. 21A-21D illustrate an example of another kingpin lock 2100 in accordance with aspects of the present disclosure. Fig. 21A illustrates kingpin lock 2100 as viewed from the underside of a trailer. Fig. 2 IB illustrates an elevation view of a semi-tractor-trailer comprisingkingpin lock 2100. Fig. 21 C illustrates a top view of kingpin lock 2100 in a first (locked) position. Fig. 21D illustrates a top view of kingpin lock 2100 in a second (unlocked) position.

[0111] In one embodiment, kingpin lock 2100 allows kingpin 2004 to engage fifth wheel 2006 when in the second position (see Figs. 21A and 21D). Kingpin lock 2100 comprises rack 2102, which engages pinion 2104. Pinion 2104 may be operated by an electrical, hydraulic, or pneumatic motor or other source of rotational force and apply the rotational force to rack 2102. The operation of pinion 2104 (or a motor operating pinion 2104) to maintain the first position and / or second position or transition therebetween may be provided by energy source 2010 (e.g., battery, generator / alternator, retained spring, pump, reservoir, etc.). Pinion 2104 may be operated to extend kingpin lock 2100, thereby shielding kingpin 2004 from fifth wheel 2006 in the first position (see Fig. 21C). In another embodiment, pinion 2104 may be operated to retract kingpin lock 2100 to the second position, thereby allowing kingpin 2004 to engage with fifth wheel 2006 (see Fig. 2 ID). The operation of pinion 2104 may be controlled by access control component 2008.

[0112] Figs. 22A-22D illustrate kingpin lock 2200 in accordance with aspects of the present disclosure. Fig. 22A illustrates kingpin lock 2200 as viewed from the underside of a trailer. Fig. 22B illustrates an elevation view of a semi-tractor-trailer comprising kingpin lock 2200. Fig. 22C illustrates a top view of kingpin lock 2200 in a first (locked) position. Fig. 22D illustrates a top view of kingpin lock 2200 in a second (unlocked) position.

[0113] In one embodiment, kingpin lock 2200 allows kingpin 2004 to engage fifth wheel 2006 when in the second position (see Fig. 22D). Kingpin lock 2200 comprises spring 2210 that applies a force to kingpin lock 2200 to maintain kingpin lock 2200 in the first position. Spring 2210 alone may be insufficient to maintain kingpin lock 2200 in the first position when a sufficient force is applied to kingpin lock 2200, such as the force applied by fifth wheel 2006 when attempting to engage kingpin 2004.

[0114] In another embodiment, solenoid 2208 extends to engage keeper 2204 and thereby maintain kingpin lock 2200 in the second position. As a benefit, kingpin lock 2200 may not engage with fifth wheel 2006 when fifth wheel 2006 has engaged kingpin 2004, which may thus reduce wear.

[0115] In another embodiment, solenoid 2208 extends to instead engage keeper 2206, thereby maintaining kingpin lock 2200 in the first position (see Fig. 3C). As a benefit, kingpin lock 2200 deters or prevents fifth wheel 2006 from engaging kingpin 2004.

[0116] Solenoid 2208 may be in a first energy state or a second energy state. Tn one embodiment, the first energy state is an energized state (e.g., solenoid 2208 requires energy to maintain the first energy state) and the second energy state is a non-energized state (e.g., solenoid 2208 does not require energy to maintain the second energy state). In another embodiment, the first energy state is a non-energized state (e.g., solenoid 2208 does not require energy to maintain the first energy state) and the second energy state is an energized state (e.g., solenoid 2208 requires energy to maintain the second energy state). Solenoid 2208 may be operated by an electrical, hydraulic, or pneumatic motor. The operation of solenoid 2208 may be provided by energy source 2010 (e.g., battery, generator / altemator, pump, reservoir, etc.) and controlled by access control component 108.

[0117] Figs. 23A-23C illustrate kingpin lock 2300 in accordance with aspects of the present disclosure. Fig. 23A illustrates an elevation view of a semi-tractor-trailer comprising kingpin lock 2300.

Fig. 23 C illustrates a top (or bottom), semi-transparent view of kingpin lock 2300 in a second (unlocked) position.

[0118] In one embodiment, hook 2302 is rotated into the first position (see Fig. 23B) to shield kingpin 2004 from fifth wheel 2006 and thereby deter or prevent fifth wheel 2006 from engaging kingpin 2004. Hook 2302 is rotationally operated by actuator2304 to maintain hook 2302 in either the first position or second position, or to transition therebetween. Actuator 2304 may be a rotary actuator, a solenoid, or other source of rotational force that is applied to hook 2302. The operation of hook 2302 (or actuator 2304) to maintain the first position and / or second position or transition therebetween may be provided by an energy source (e.g., a battery, generator / altemator, retained spring, pump, reservoir, etc.) as controlled by control component 2008. In the first position, hook 2302 contacts fifth wheel 2006 to prevent fifth wheel 2006 from engaging kingpin 2004. In another embodiment, kingpin lock 2300 is rotated by actuator 2304 to the second position to allow kingpin 2004 to engage fifth wheel 2006.

[0119] Figs. 24A and 24B illustrate an example of another kingpin lock 2400 in accordance with aspects of the present disclosure. Fig. 24A illustrates kingpin lock 2400 as viewed from the underside of a trailer. Fig. 24B, in insert 2406, illustrates an elevation view of a semi-tractor-trailer comprising kingpin lock 2400, whereas the remainder of Fig. 24B illustrates a top view of kingpin lock 2400. Figs. 24A and 24B (see insert 2406) illustrate kingpin lock 2400 in a first (locked)position. Kingpin lock 2400 in a second (unlocked) position occurs when blocker 2404 is retracted into kingpin lock body 2402 (not shown).

[0120] In one embodiment, kingpin lock 2400 allows kingpin 2004 to engage fifth wheel 2006 when in the second position (i.e., blocker 2404 retracted into kingpin lock body 2402 or otherwise moved so as to not obscure kingpin 2004). Kingpin lock 2400 comprises blocker 2404, which may be operated via a motor or other actuator operated by an electrical, hydraulic, or pneumatic motor or other source of longitudinal and / or rotational force that is applied to blocker 2404. The operation of blocker 2404 (or a motor operating blocker 2404) to maintain the first position and / or second position or transition therebetween may be provided by energy source 2010 (e.g., battery, generator / altemator, retained spring, pump, reservoir, etc.). Blocker 2404 may be operated to extend blocker 2404 to shield kingpin 2004 from fifth wheel 2006 in the second position (see Figs.24A and 24B).
