BACKGROUND OF THE INVENTION

The present invention generally relates to shipping containers.

Shipping containers today have their doors “locked” by using an ISO standard mechanical bolt seal. In this arrangement, a bolt with a unique (to the manufacturer) serial numbered bolt is inserted into the right hand container door lock hasp and is secured in-place with a bolt housing containing the same serial number. The bolt needs to be cut with bolt cutters to be removed. Although there is an ISO standard for these bolts, they are not necessarily identical from one manufacturer to another. Variations include the length and diameter of the bolt and the mechanical locking mechanism that secures the bolt to its mated housing.

The abovementioned products and concepts have been universally accepted by industry. Although far from fool proof, the technique does provide a simple method of keeping the doors on shipping containers closed unless deliberate action is taken to cut the bolt. It is quite common for bolts to be cut and containers opened and then re-sealed as the containers travel from origin to destination. Unfortunately, there is no means readily available for determining when or where bolts were cut and replaced. Without this knowledge, an end shipper has no recourse to determine when a container bolt has been removed and replaced. Theft or loss assignment, therefore, can be difficult at best.

A need exists for improvement in securing, monitoring, and tracking shipping containers. This, and other needs, are addressed by one or more aspects of the present invention.

DETAILED DESCRIPTION

As a preliminary matter, it will readily be understood by one having ordinary skill in the relevant art (“Ordinary Artisan”) that the present invention has broad utility and application. Furthermore, any embodiment discussed and identified as being “preferred” is considered to be part of a best mode contemplated for carrying out the present invention. Other embodiments also may be discussed for additional illustrative purposes in providing a full and enabling disclosure of the present invention. Moreover, many embodiments, such as adaptations, variations, modifications, and equivalent arrangements, will be implicitly disclosed by the embodiments described herein and fall within the scope of the present invention.

Accordingly, while the present invention is described herein detail in relation to one or more embodiments, it is to be understood that this disclosure is illustrative and exemplary of the present invention, and is made merely for the purposes of providing a full and enabling disclosure of the present invention. The detailed disclosure herein of one or more embodiments is not intended, nor is to be construed, to limit the scope of patent protection afforded the present invention, which scope is to be defined by the claims and the equivalents thereof. It is not intended that the scope of patent protection afforded the present invention be defined by reading into any claim a limitation found herein that does not explicitly appear in the claim itself.

Thus, for example, any sequence(s) and/or temporal order of steps of various processes or methods that are described herein are illustrative and not restrictive. Accordingly, it should be understood that, although steps of various processes or methods may be shown and described as being in a sequence or temporal order, the steps of any such processes or methods are not limited to being carried out in any particular sequence or order, absent an indication otherwise. Indeed, the steps in such processes or methods generally may be carried out in various different sequences and orders while still falling within the scope of the present invention. Accordingly, it is intended that the scope of patent protection afforded the present invention is to be defined by the appended claims rather than the description set forth herein.

Additionally, it is important to note that each term used herein refers to that which the Ordinary Artisan would understand such term to mean based on the contextual use of such term herein. To the extent that the meaning of a term used herein—as understood by the Ordinary Artisan based on the contextual use of such term—differs in any way from any particular dictionary definition of such term, it is intended that the meaning of the term as understood by the Ordinary Artisan should prevail.

Furthermore, it is important to note that, as used herein, “a” and “an” each generally denotes “at least one,” but does not exclude a plurality unless the contextual use dictates otherwise. Thus, reference to “a picnic basket having an apple” describes “a picnic basket having at least one apple” as well as “a picnic basket having apples.” In contrast, reference to “a picnic basket having a single apple” describes “a picnic basket having only one apple.”

When used herein to join a list of items, “or” denotes “at least one of the items,” but does not exclude a plurality of items of the list. Thus, reference to “a picnic basket having cheese or crackers” describes “a picnic basket having cheese without crackers”, “a picnic basket having crackers without cheese”, and “a picnic basket having both cheese and crackers.” Finally, when used herein to join a list of items, “and” denotes “all of the items of the list.” Thus, reference to “a picnic basket having cheese and crackers” describes “a picnic basket having cheese, wherein the picnic basket further has crackers,” as well as describes “a picnic basket having crackers, wherein the picnic basket further has cheese.”

Referring now to the drawings, one or more preferred embodiments of the present invention are next described. The following description of one or more preferred embodiments is merely exemplary in nature and is in no way intended to limit the invention, its implementations, or uses.

FIG. 1 is an illustration of a conventional shipping container 6 having an electronic locking system 10 installed thereon, for securing the container 6, in accordance with one or more aspects of the present invention. Such shipping containers conventionally utilize a latching assembly to maintain the container door or doors 8 in a closed state, and such latching assembly frequently includes a hasp mechanism 16. A bolt seal 14 commonly used to lock shipping container doors 8 is shown in FIG. 1A, and includes a bolt 15 and locking housing assembly 17.

FIG. 2 is a schematic perspective illustration of a first variation of the electronic locking system 10 of FIG. 1. The system 10 includes an electronic locking device 12; a bolt seal 14; and a container hasp 16.

The container hasp 16 is found in the latching assemblies of conventional shipping containers. The bolt seal 14 also is conventional and preferably includes a mechanical bolt 15 and locking housing assembly 17, which are shown in FIG. 1A. Furthermore, a serial number may be printed on the bolt and on the locking housing. However, an electronic bolt seal may be used in conjunction with the invention, too.

The electronic locking device 12 includes a rugged mechanical housing 18 supporting an upper pivot arm 22 and a lower pivot arm 24. Each of these will be described in greater detail hereinbelow.

FIGS. 3 and 4 are more detailed schematic illustrations of the electronic locking system 10 of FIG. 1, shown in a locked configuration and an unlocked configuration, respectively. As shown therein, the housing 18 of the electronic locking device 12 includes a pivot arm support carriage 20, which is preferably enclosed except for the pivot arms 22,24 extending therefrom; a sealed compartment 26 containing sensor electronics (not shown, but schematically indicated in FIG. 3-4) and one or more batteries (not shown, but schematically indicated in FIG. 3-4); and a barrier 28 to prevent access to the electronics compartment 26 from the pivot arm support carriage 20. The housing 18 may be attached to the container 6 by any conventional means, such as by magnets, adhesive, bolts, or the like, and is preferably attached in a way so as not to damage the integrity of the container wall to which it is attached. Preferably, the housing 18 is attached to the container door 8 rare earth magnets that are mounted in the housing 18.

The upper pivot arm 22 has a proximal end, which is located within the pivot arm support carriage 20, and a distal end. The upper pivot arm 22 pivots about a point located on or near its proximal end. In the first variation of the system 10, the upper pivot arm 22 includes the following features along its length, from proximal end to distal end: a pivot or swivel 46; a sensing contact 30, preferably disposed within the pivot arm support carriage 20, that closes a circuit when the electronic locking device 12 is in the locked configuration (as shown in FIGS. 2 and 3) and opens the circuit when the electronic locking device 12 is in the unlocked configuration (as shown in FIG. 4); a bolt or pin (hereinafter pin or bolt 32) that is inserted through the container hasp 16 to secure the container 6; and an opening 34 adapted to receive the bolt 15 of the bolt seal 14 therethrough.

The lower pivot arm 24 has a proximal end, which is located within the pivot arm support carriage 20, and a distal end. Like the upper pivot arm 22, the lower pivot arm 24 pivots about a point located on or near its proximal end. In the first variation of the system 10, the lower pivot arm 24 includes the following features along its length, from proximal end to distal end: a pivot or swivel 47; a sensing contact 31, preferably disposed within the pivot arm support carriage 20, that closes the pivot arm circuit, by making contact or coming in close proximity with the sensing contact 30 on the upper pivot arm 22, when the electronic locking device 12 is in the locked configuration (as shown in FIGS. 2 and 3) and opens the circuit when the electronic locking device 12 is in the unlocked configuration (as shown in FIG. 4), a bolt receptacle 36 that receives therein the bolt 32 inserted through the container hasp 16; and an opening 34 adapted to receive the bolt 15 of the bolt seal 14 therethrough.

In the locked configuration, shown in FIGS. 2 and 3, the bolt 15 of the bolt seal 14 has been inserted through the openings 34,35 of the pivot arms 22,24 and received in locking engagement within the locking housing assembly 17 of the bolt seal 14. Furthermore, because the pivot arms 22,24 have been rotated toward each other, the security bolt 32 has been inserted through the container hasp 16 and received within the bolt receptacle 36, and the sensing contacts 30 are placed in contact or sufficiently close disposition with each other so as to close the pivot arm circuit, thereby indicating that the locking arms 22,24 are closed. It further will be appreciated that the bolt 32 and bolt receptacle 36 function as a stop limiting the further closing of the arms 22,24. Moreover, the receipt of the bolt 32 through the hasp and within the bolt receptacle 36 precludes removal of the locking device from the hasp with the arms 22,24 are in the locked configuration.

In the unlocked configuration of the electronic locking device 12, shown in FIG. 4, the pivot arms 22,24 have been rotated away from each other; the security bolt 32 has been removed from the bolt receptacle 36 and the container hasp 16; and the sensing contacts 30 are out of contact or sufficiently far apart so as to open the pivot arm circuit, thereby indicating that the locking arms 22,24 are open. The locking arms 22,24 being open may, in turn, be interpreted by the sensor electronics 42, or by a human operator, to mean that the bolt seal 14 has been removed and that the container door 8 may have been opened.

The pivot arm circuit, of which the contacts 30 form a part, may be any circuitry adapted to detect, via the sensing contacts 30, an “open” state and a “closed” state. The sensing contacts 30 may be or include electrical contacts, optoelectronic contacts or sensors, magnetic reed switch contacts, proximity sensor or any other suitable electrical, mechanical, electromechanical, optoelectrical sensor or contact. The circuitry for detecting the binary (“open” or “closed”) state may vary according to the sensor or contact design, based on power, space or circuit technology, or the like, so long as a binary input (representing “open” or “closed”) is passed along to the sensor electronics 42.

The sensor electronics 42 may be any electronics adapted to relay or pass along state information about the pivot arm circuit to an external recipient, whether through digital or analog, wired or wireless signal or transmission, by audio or visual signal for perception by appropriate personnel, or the like, such as by electrical, optical or magnetic data link. The state information may include the existence of an “open” state in the pivot arm circuit, the existence of a “closed” state in the pivot arm circuit, or both; the transition from a “closed” state to an “open” state in the pivot arm circuit, an “open” state to a “closed” state in the pivot arm circuit, or both; or the like. In at least some embodiments, the state information alternatively or additionally includes information related to any of the foregoing, and may include information about multiple occurrences of any of the foregoing.

Such state information further may include, but is not limited to, the time of such transition, the duration of a state, the location of the device 12 at the time, or other conditions at the device 12 or within or without the container 6. Such information and conditions may be determined, detected, or the like using built-in or integrated circuitry or technology or may be relayed or reported to the sensor electronics 42 from separate components. In at least some embodiments, such information and conditions may be relayed through one or more communication devices, such as by “hopping.” Various aspects of sensor electronics, sensors, and the like, suitable for use in the present invention, are disclosed in the aforementioned U.S. patent application Ser. No. 11/460,976, published as US 2008-0315596 A1, as well as other of the incorporated references.

In particular, the device may be used to detect any opening or closing of the pivot arms 22,24, thus providing a strong indication as to whether the container door hasp 16 is secure. In particular, if the pivot arms 22,24 are opened (or are no longer closed), there is an excellent likelihood (although not conclusive in and of itself) that the container door 8 has been opened. This, in turn, may indicate to an operator that contents have been added to or removed from the container 6. The sensor electronics 42 preferably sense every opening and closing of the pivot arms 22,24; record the time of the event; and if within wireless transmission range of an applicable communication device (e.g., a reader), then report the event, else store the information until such communications are available and the information can be reported.

Optionally, or alternatively, the information may not be wireless communicated from the electronic locking device 12 and, instead, acquired by download via a USB port or other interface. A locking housing assembly of a bolt seal, including a USB port, is disclosed, for example, in U.S. patent application Ser. No. 11/460,976, published as US 2008-0315596 A1, as well as other of the incorporated references.

In an exemplary method of use, a human operator installs the electronic locking device 12 by opening the pivot arms 22,24 of the device 12 and positioning them above and below the staple portion of the hasp mechanism such that the bolt 32 may be inserted through the hasp 16. Once the bolt 32 is aligned with the hasp 16, the pivot arms 22,24 may be rotated toward each other such that the bolt 32 is guided through the hasp 16. The rotation of the pivot arms 22,24 also brings the contacts 30 together, placing them in contact or close disposition with each other and closing the pivot arm circuit, as described previously. The bolt 15 of a bolt seal 14 may then be installed through the openings 34 in the distal ends of the pivot arms 22,24, and conventional procedures for such installations are carried out.

When the container is to be opened, conventional procedures may be carried out with regard to the removal of the bolt seal 14. Once the bolt seal is removed, the pivot arms 22,24 of the device 12 may be opened once again, thereby retracted the bolt 32 from the hasp and permitting the device 12 to be removed therefrom. With the device 12 removed, the latching assembly of the shipping container 6 may be manipulated normally to permit opening of the door 8.s

It will be appreciated that, in order to prevent tampering, the bolt 32 and the receptacle 36 may be designed so as to minimize the possibility that the bolt 32 is cut, broken, destroyed or its integrity is otherwise damaged, which would permit the device 12 from being removed from the hasp 16 without opening the pivot arms 22,24. The design may include particular geometries, materials, and the like to make it very difficult for an individual to gain access in this way.

Optionally or alternatively to the contacts 30,31, in a feature of the electronic locking device 12, the security bolt 32 and the bolt receptacle 36 may include contacts and serve to close the pivot arm circuit when the arms are in the closed position, and open the pivot arm circuit when the arms are in the open position. In this variation, contacts 30,31 as shown in FIGS. 2-4. This is somewhat disadvantageous, as the contacts are not enclosed and protected by the housing 18. However, this is somewhat advantageous because cutting of the bolt 32 for removal of the electronic locking device 12 (without removing the bolt seal 14) would then be detected, in that the cutting of the bolt or pine 32 would break the pivot arm circuit.

FIG. 5 is a schematic illustration of a second variation of an electronic locking system 110 for securing a shipping container 6 in a locked configuration in accordance with one or more aspects of the present invention. The system 110 includes an electronic locking device 112; bolt seal 14; and container hasp 16. The electronic locking device 112 includes a rugged mechanical housing 118 supporting an upper pivot arm 122 and a lower pivot arm 124. The rugged mechanical housing 118 includes: a pivot arm support carriage 120, which is preferably enclosed except for the pivot arms 122,124 extending therefrom; a sealed compartment 126 containing sensor electronics (not shown, but schematically indicated in FIG. 3-4) and one or more batteries (not shown, but schematically indicated in FIG. 3-4); and a barrier 128 to prevent access to the electronics compartment 126 from the pivot arm support carriage 120.

The upper pivot arm 122 has a proximal end, which is located within the pivot arm support carriage 120, and a distal end. The upper pivot arm 122 pivots about a point located on or near its proximal end. In the second variation of the system 110, the upper pivot arm 122 includes the following features along its length, from proximal end to distal end: a pivot or swivel 146; a sensing contact 130, preferably disposed within the pivot arm support carriage 120, that closes a circuit when the electronic locking device 112 is in a locked configuration (as shown in FIG. 5) and opens the circuit when the electronic locking device 112 is in an unlocked configuration (not shown); an opening 134 adapted to receive the bolt of a bolt seal 14 therethrough; and a bolt or pin 132 that is inserted through the container hasp 16 to secure the container 6.

The lower pivot arm 124 has a proximal end, which is located within the pivot arm support carriage 120, and a distal end. Like the upper pivot arm 122, the lower pivot arm 124 pivots about a point located on or near its proximal end. In the second variation of the system 110, the lower pivot arm 124 includes the following features along its length, from proximal end to distal end: a pivot or swivel 146; a sensing contact 130, preferably disposed within the pivot arm support carriage 120, that closes the pivot arm circuit, by making contact or coming in close proximity with the sensing contact 131 on the upper pivot arm 122, when the electronic locking device 112 is in a locked configuration (as shown in FIG. 5) and opens the circuit when the electronic locking device 112 is in an unlocked configuration (not shown); an opening 1345 adapted to receive the bolt 15 of a bolt seal 14 therethrough; and a bolt receptacle 136 that receives the bolt or pin 132 inserted through the container hasp 16.

In the locked configuration, shown in FIG. 5, the bolt 15 of the bolt seal 14 has been inserted through the openings 34,35 of the pivot arms 122,124 and received in locking engagement within the locking housing assembly 17 of the bolt seal 14. Furthermore, because the pivot arms 122,124 have been rotated toward each other, the security bolt or pin 132 has been inserted through the container hasp 16 and engaged with the bolt receptacle 136, and the sensing contacts 130 are placed in contact or close disposition with each other, thereby closing the pivot arm circuit and indicating that the locking arms 122, 124 are closed.

FIG. 6 is a schematic illustration of a third variation of an electronic locking system 210 for securing a shipping container 6 in a locked configuration in accordance with one or more aspects of the present invention. The system 210 includes an: electronic locking device 212; a bolt seal 14; and a container hasp 16. The electronic locking device 212 includes a rugged mechanical housing 218 supporting an upper pivot arm 222 and a lower pivot arm 224. The rugged mechanical housing 218 includes: a pivot arm support carriage 220, which is preferably enclosed except for the pivot arms 222,224 extending therefrom; a sealed compartment 226 containing sensor electronics (not shown, but schematically indicated in FIG. 3-4) and one or more batteries (not shown, but schematically indicated in FIG. 3-4); and a barrier 228 to prevent access to the electronics compartment 226 from the pivot arm support carriage 220.

The upper pivot arm 222 has a proximal end, which is located within the pivot arm support carriage 220, and a distal end. The upper pivot arm 222 pivots about a point located on or near its proximal end. In the third variation of the system 210, the upper pivot arm 222 includes the following features along its length, from proximal end to distal end: a sensing contact 230 within the pivot arm support carriage 220 that closes a circuit when the electronic locking device 212 is in a locked configuration (as shown in FIG. 6) and opens the circuit when the electronic locking device 212 is in an unlocked configuration (not shown); a pivot or swivel 246; a bolt or pin 232 that is inserted through the container hasp 16 to secure the container 6; and an opening 234 adapted to receive the bolt of a bolt seal 14 therethrough.

The lower pivot arm 224 has a proximal end, which is located within the pivot arm support carriage 220, and a distal end. Like the upper pivot arm 222, the lower pivot arm 224 pivots about a point located on or near its proximal end. In the third variation of the system 210, the lower pivot arm 224 includes the following features along its length, from proximal end to distal end: a sensing contact 230 within the pivot arm support carriage 220 that closes the pivot arm circuit, by making contact or coming in close proximity with the sensing contact 231 on the upper pivot arm 222, when the electronic locking device 212 is in a locked configuration (as shown in FIG. 6) and opens the circuit when the electronic locking device 212 is in an unlocked configuration (not shown); a pivot or swivel 247, a bolt receptacle 236 that receives the bolt or pin 232 inserted through the container hasp 16; and an opening 234 adapted to receive the bolt of a bolt seal 14 therethrough.

In the locked configuration, shown in FIG. 6, the bolt 15 of the bolt seal 14 has been inserted through the openings 234,235 of the pivot arms 222,224 and received in locking engagement within the locking housing assembly 17 of the bolt seal 14. Furthermore, because the pivot arms 222,224 have been rotated toward each other, the security bolt or pin 232 has been inserted through the container hasp 16 and engaged with the bolt receptacle 236, and the sensing contacts 230 are placed in contact or close disposition with each other, thereby closing the pivot arm circuit and indicating that the locking arms 222, 224 are closed.

In order to make it possible to open the pivot arms 222,224 a sufficient distance to permit the bolt or pin 232 to be inserted through the hasp 16, it will be understood that the respective contacts 230 are offset from one another such that rotation of the pivot arms 222,224 into the closed position causes adjacent sides of the contacts 230, rather than ends thereof, to be placed in abutment or proximity with each other, in a motion that in some ways may be similar to the closing of a pair of scissors. Suitable geometry for such an arrangement will be apparent to the Ordinary Artisan.

FIG. 7 is a schematic illustration of a fourth variation of an electronic locking system 310 for securing a shipping container 6 in a locked configuration in accordance with one or more aspects of the present invention. The system 310 includes: an electronic locking device 312; a bolt seal 14; and a container hasp 16. The electronic locking device 312 includes: a rugged mechanical housing 318 supporting an upper pivot arm 322; and a lower fixed arm 324. The rugged mechanical housing 318 include: a pivot arm support carriage 320, which is preferably enclosed except for the upper pivot arm 322, and lower fixed arm 324 extending therefrom; a sealed compartment 326 containing sensor electronics (not shown, but schematically indicated in FIG. 3-4) and one or more batteries (not shown, but schematically indicated in FIG. 3-4); and a barrier 328 to prevent access to the electronics compartment 326 from the pivot arm support carriage 320.

The upper pivot arm 322 has a proximal end, which is located within the pivot arm support carriage 320, and a distal end. The upper pivot arm 322 pivots about a point located on or near its proximal end. In the fourth variation of the system 310, the upper pivot arm 322 includes the following features along its length, from proximal end to distal end: a pivot or swivel 346; a sensing contact 330, preferably disposed within the pivot arm support carriage 320, that closes a circuit when the electronic locking device 312 is in a locked configuration (as shown in FIG. 7) and opens the circuit when the electronic locking device 312 is in an unlocked configuration (not shown); a bolt or pin 332 that is inserted through the container hasp 16 to secure the container 6; and an opening 334 adapted to receive the bolt of a bolt seal 14 therethrough.

The lower fixed arm 324 has a proximal end, which is located within the pivot arm support carriage 320, and a distal end. Unlike the upper pivot arm 322, the lower pivot arm 324 does not pivots about a point located on or near its proximal end, but rather, is fixed in place. In the fourth variation of the system 310, the lower fixed arm 324 includes the following features along its length, from proximal end to distal end: a sensing contact 331; preferably disposed within the pivot arm support carriage 320, that closes the pivot arm circuit, by making contact or coming in close proximity with the sensing contact 330 on the upper pivot arm 322, when the electronic locking device 312 is in a locked configuration (as shown in FIG. 7) and opens the circuit when the electronic locking device 312 is in an unlocked configuration (not shown); a bolt receptacle 336 that receives the bolt or pin 332 inserted through the container hasp 16; and an opening 335 adapted to receive the bolt 15 of the bolt seal 14 therethrough.

In the locked configuration, shown in FIG. 7, the bolt 15 of the bolt seal 14 has been inserted through the opening 334 of the pivot arm 322, inserted through the opening 335 of the fixed arm 324, and received in locking engagement within the locking housing assembly 17 of the bolt seal 14. Furthermore, when the upper pivot arm 322 has been rotated toward the lower fixed arm 324, the security bolt or pin 332 has been inserted through the container hasp 16 and engaged with the bolt receptacle 336, and the sensing contacts 330 are placed in contact with or sufficiently close proximity to each other so as to close the pivot arm circuit, thereby indicating that the locking arms 322,324 are closed.

In an alternative embodiment to that of the electronic locking device 312, the upper arm is fixed and the lower arm rotates in otherwise similar manner and enabled by similar structure to that of the electronic locking device 312.

FIG. 8 is a schematic illustration of a fifth variation of an electronic locking system 410 for securing a shipping container 6 in a locked configuration in accordance with one or more aspects of the present invention. The system 410 includes an electronic locking device 412; a bolt seal 14; and container hasp 16. The electronic locking device 412 includes a removable pivot arm assembly 421 supporting an upper pivot arm 422 and a lower pivot arm 424, and a rugged mechanical housing 418. The rugged mechanical housing 418 includes: a pivot arm support carriage 420, into which the removable pivot arm assembly 421 can be inserted; a compartment 426 containing sensor electronics (not shown, but schematically indicated in FIG. 3-4) and one or more batteries (not shown, but schematically indicated in FIG. 3-4); an upper pivoting member 450; a lower pivoting member 452; and and a barrier 428 that partially limits access to the electronics compartment 426 from the pivot arm support carriage 420. The upper and lower pivoting members 450,452 are anchored within the compartment 426 and extend across the barrier 428 into the pivot arm support carriage 420, where they engage the pivot arms when the system 410 is in a locked configuration, as shown in FIG. 8.

In the fifth variation of the system 410, the upper pivot arm 422 is supported by the removable pivot arm assembly 421; has two arm segments 423,425 both of which extend from the pivot arm assembly 421; and pivots about a point located within the pivot arm assembly 421. The shorter of the arm segments 423,425 ends extends into the pivot arm support carriage 420 when the pivot arm assembly 421 is inserted into the housing 418 and engages with the upper pivoting member 450 to secure the removable pivot arm assembly 421 within the pivot arm support carriage 420. The longer arm segment 425 of the upper pivot arm 422 includes the following features along its length, extending away from the pivot arm assembly 421: a bolt or pin 432 that is inserted through the container hasp 16 to secure the container 6; and an opening 434 adapted to receive the bolt 15 of a bolt seal 14 therethrough.

The lower pivot arm 424 also is supported by the removable pivot arm assembly 421; has two arm segments 427,429 both of which extend from the pivot arm assembly 421; and, like the upper pivot arm 422, pivots about a point located within the pivot arm assembly 421. The shorter of the arm segments 427 extends into the pivot arm support carriage 420 when the pivot arm assembly 421 is inserted into the housing 418 and engages with the lower pivoting member 452 to secure the removable pivot arm assembly 421 within the pivot arm support carriage 420. The longer arm segment 429 of the lower pivot arm 424 includes the following features along its length, extending away from the pivot arm assembly 421: a bolt receptacle 436 that receives the bolt or pin 432 inserted through the container hasp 16; and an opening 434 adapted to receive the bolt 15 of the bolt seal 14 therethrough.

Within the electronics compartment 426, the upper and lower pivoting members 450,452 are located near sensing contacts 430. When the electronic locking device 412 is in a locked configuration (as shown in FIG. 8), engagement by the ends of the arm segments 423,427 cause the pivoting members 450,452 to pivot such that contact is made with the sensing contacts 430, whereby the pivot arm circuit of the electronic locking device 410 is closed.

FIGS. 9-11 are schematic illustrations of a further variation of an electronic locking device 512 for securing a shipping container 6 in a locked configuration in accordance with one or more aspects of the present invention. The structure of the device 512 is similar to the device 12 of FIGS. 2-4, and for brevity, only differences in the two devices 12,512 are described and shown in FIGS. 9-10.

In particular, the electronic locking device 512 includes a compression spring 560 that biases the pivot arms 522,524 apart, toward the open position. The compression spring 560 is schematically shown encompassing the contacts 530,531; however, it is contemplated that the compression spring may not encompass the contacts 530,531 while still serving to bias the pivot arms 522,524 toward the open position. When the electronic locking device 512 is in the closed configuration, the bolt seal 14 holds the arms in the closed position against the force of the compressed spring 512, as represented by the opposed arrows 562 shown in FIG. 9. The electronic locking device 512 is schematically shown in a closed or locked configuration in FIG. 9 and in an open or unlocked configuration in FIG. 10. Furthermore, it will be understood and appreciated that any of the foregoing embodiments of the electronic locking device may include a spring for tensioning of the device into an open or unlocked configuration.

Finally, FIG. 11 illustrates a specific variant of the electronic locking device having a compression spring 660, wherein the bolt or pin 664 is received within the bolt receptacle in locking engagement therewith, whereby a bolt seal 14 is unnecessary. In this case, the bolt or pin 664 holds the pivot arms closed against the force of the spring 660 when in the closed configuration. The bolt or pin 664 also is cut in order to return the electronic locking device 612 to the open or unlocked configuration. Moreover, the cut remnants of the bolt or pin 664 preferably are readily removed and replaced with a new bolt or pin for relocking of the device 612. For instance, the upper end of the bolt or pin 664 may be received in threaded engagement within the subcomponent 690 and readily unscrewed after cutting of the bolt or pin.

Finally, it will be noted that one or more of the foregoing embodiments may be utilized not only with hasps of door latching assemblies of shipping containers, but in other ways, such as in combination with a lid or other element of a shipping conveyance.

It will be apparent to the Ordinary Artisan that the various features, variations, methods of use, implementations, sensor electronics functionality, and the like, described previously with regard to FIGS. 2-4, are equally applicable, except where by their nature such applicability is inappropriate, to the other variations described herein with reference to FIGS. 5-11.

Based on the foregoing description, it will be readily understood by those persons skilled in the art that the present invention is susceptible of broad utility and application. Many embodiments and adaptations of the present invention other than those specifically described herein, as well as many variations, modifications, and equivalent arrangements, will be apparent from or reasonably suggested by the present invention and the foregoing descriptions thereof, without departing from the substance or scope of the present invention.

Accordingly, while the present invention has been described herein detail in relation to one or more preferred embodiments, it is to be understood that this disclosure is only illustrative and exemplary of the present invention and is made merely for the purpose of providing a full and enabling disclosure of the invention. The foregoing disclosure is not intended to be construed to limit the present invention or otherwise exclude any such other embodiments, adaptations, variations, modifications or equivalent arrangements, the present invention being limited only by the claims appended hereto and the equivalents thereof
