Abstract
This invention pertains to a mechanism for securing a container. The container includes at least one wall, which is comprised of at least a first door. The mechanism includes a first rod, which is attached with the outer surface of the first door. The first rod is capable of being rotated from an openable position, when the first door is capable of being opened, to a closed position, when the first door is engaged with the container to be closed. The mechanism further includes a channel member, which is attached with the inner surface of the first door, and a sliding member, which is slidably received within the channel member. The sliding member is engageable with the first rod. As the first rod is rotated from the openable position to the closed position, engagement of the first rod with the sliding member causes the sliding member to slide to secure the first door. In one embodiment, a second door is provided, which is secured by inserting a pin attached with a bottom portion of the inner surface of the second door into a pin engaging hole defined in the floor of the container. In one embodiment, after the doors are secured, and a lock is inserted into padlock tabs of a locking device, the doors are prevented from being opened unless the lock is removed.
Description




DESCRIPTION OF THE INVENTION




Field of the Invention




This invention relates to a locking system for securing one or more doors of a container and, more particularly, to such a locking system including a sliding member securing mechanism.




BACKGROUND OF THE INVENTION




There are various types of containers that may be used to transport and/or store materials. One type of container is a cargo style shipping container. Cargo style shipping containers typically are rectangular in shape, and have four side walls, a top wall, and a bottom wall. While the size of cargo style containers may vary, there are two sizes of this type of container in general use: one size is about 8 feet in height, about 8 feet in width, and about 20 feet in length, and the other size is about 8 feet in height, about 8 feet in width, and about 40 feet in length.




Cargo style shipping containers may be used to transport large volumes of materials from location to location around the world. These large containers can store large quantities of materials and may be effectively transported on boats, trains, trucks, and the like in order to expeditiously arrive at their eventual destination. The detachability and adaptability of these containers is important because the containers will often changes hands from one carrier to another carrier, such as from a train to a trucking company or from a trucking company to a steamship line, during the transport.




Because of the great volume and often valuable nature of the materials transported within the container, security is an important consideration during the transport of the materials. Thus, these containers are usually sealed and/or locked in some manner to prevent an unauthorized person from gaining access into the container.




Another use of a cargo style shipping container is as a storage mechanism for additional storage space. For example, such a container could be used by a school, a hospital, a contractor, or the like to store materials on-site. Often, these containers are used only temporarily by such entities. As with the use of containers for transport, while in use for storage, the containers typically need to be securely locked to protect the materials within the container.




Generally, at least one wall of the container comprises a pair of doors, similar to doors on a barn, which may be opened or closed to gain or prevent access to the interior of the container, respectively. To close the container, a first door is swung closed, the second door is then swung closed, and the doors are locked. Each door is typically closed using an external latch rod having a handle. Movement of the handle in turn moves the external latch rod so that latches at the top and bottom of the latch rod engage with protrusions that protrude from the door frame at the top and bottom of the container. Then, after the doors are closed, at least one of the handles is locked in place, such as by using a padlock or other locking device, to lock the containers and prevent access to the interior of the container.




It is generally known in the art to protect the locking mechanism, such as a padlock, by the use of a protective cover. However, a person may sever the external latch rod, which would then allow access to the interior of the container and, thus, the materials within the container. More particularly, if the external latch rod is severed, an intruder may bypass the padlock and open the door by rotating the latch rod (which is then free of the handle) while the handle remains locked by the padlock. While protecting the locking mechanism prevents an intruder from gaining access to the container by tampering with the padlock, those types of improvements do not protect the securing mechanism (i.e., the external latch rod).




Thus, to better prevent unauthorized access to storage containers like those described above, a mechanism which protects the securing mechanism from tampering, as well as preventing tampering with the actual locking mechanism, is desired.




SUMMARY OF THE INVENTION




The present invention provides a mechanism for securing a container. The container includes at least one wall. The at least one wall includes at least a first door and a second door which has an inner surface and an outer surface.




The mechanism includes a first rod, which is attached with the outer surface of the first door. The first rod is capable of being rotated from an openable position, when the first door is capable of being opened, to a closed position, when the first door is engaged with the container to be closed. The mechanism includes a channel member, which is attached with the inner surface of the first door. The mechanism includes a sliding member slidably received within the channel member. The sliding member is also engageable with the first rod. As the first rod is rotated from the openable position to the closed position, engagement of the first rod with the sliding member causes the sliding member to slide to secure the first door.




In one embodiment, the at least one wall further comprises a second portion, and a portion of the sliding member slides behind an inner surface of the second portion to secure the first door. In one embodiment, the second portion is a second door.




In one embodiment, the container includes a first handle attached to the first rod. Movement of the first handle in turn rotates the first rod from the openable position to the closed position.




In one embodiment, the mechanism includes an engaging member for engaging the sliding member with the first rod. The engaging member is attached with the first rod when the first rod is in the closed position. In an exemplary embodiment, the engaging member is welded to the first rod.




In one embodiment, the mechanism includes a plate attached to the inner surface of the first door so that the channel member is attached to the plate to be attached with the inner surface of the first door. In an exemplary embodiment, the plate is attached to the inner surface of the first door using screws and the channel member is attached to the plate by welding.




In one embodiment, the mechanism includes a pair of tabs. One tab is attached with the outer surface of the first door and the other tab is attached with the first rod. Each tab defines an opening therein, and the openings defined in the tabs align with each other when the first rod is rotated to be in the closed position. A locking device may be inserted into the openings defined in the tabs to lock the first door in the closed position. In addition, a cover may be attached with the outer surface of the first door so as to cover the pair of tabs and the locking device.




In one embodiment, when the at least one wall comprises two doors, the mechanism includes a pin attached with a bottom portion of the inner surface of the second door and a pin engaging hole defined in a floor of the container. The pin is inserted into the pin engaging hole to lock the second door to the container.




The present invention also provides a method of securing a container. The container includes at least one wall that includes at least a first door. The first door includes an inner surface and an outer surface. The container includes a first rod. The first rod is attached with the outer surface of the first door. The first rod is capable of being rotated from an openable position, when the first door is capable of being opened, to a closed position, when the first door is engaged with the container to be closed. The container includes a channel member attached with the inner surface of the first door. The container also includes a sliding member slidably received within the channel member. The sliding member is engageable with the first rod.




The method comprises the step of rotating the first rod from the openable position to the closed position to slide the sliding member within the channel member to secure the first door.




In one embodiment, the at least one wall further comprises a second portion, and a portion of the sliding member slides behind an inner surface of the second portion to secure the first door. In one embodiment, the second portion is a second door.




In one embodiment, the container further includes an engaging member for engaging the sliding member with the first rod. The engaging member is attached with the first rod when the first rod is in the closed position. The step of rotating the first rod includes moving the engaging member to slide the sliding member within the channel member.




In one embodiment, when the at least one wall comprises two doors, the step of rotating the first rod is preceded by the step of locking the second door by inserting a pin attached with a bottom portion of the inner surface of the second door into a pin engaging hole defined in a floor of the container.




In one embodiment, the container further includes a pair of tabs. One tab is attached with the outer surface of the first door and the other tab is attached with the first rod. Each tab defines an opening therein, and the openings defined in the tabs align with each other when the first rod is rotated to be in the closed position. In this embodiment, the step of rotating the first rod is followed by the steps of inserting a locking device into openings defined in the pair of tabs; and locking the locking device. In one embodiment, the method then includes the step of placing a cover over the pair of tabs and the locking device.

. The container


10


may comprise a variety of shapes and sizes. In one embodiment, the container


10


generally has a rectangular shape. With respect to cargo style shipping containers, there are generally two different sizes in use: one being about 8 feet in width, 8 feet in height, and 20 feet in length, and the other being about 8 feet in width, 8 feet in height, and 40 feet in length.




At least one of the side walls of the container


10


is capable of being opened to allow a person to gain access to the interior of the container


10


. While, as shown in

FIG. 1

, it is side wall


12


that is openable to the interior, it should be noted that any one of the side walls


12


,


14


,


16


, or


18


, or even top wall


22


of the container


10


may be the wall that is capable of being opened to gain access to the interior of the container


10


.





FIG. 2

is a plan view of the outside of side wall


12

12


also includes a second portion


40


. The second portion


40


may comprise a portion of side wall


12


that is fixed with respect to the other walls of container


10


and, thus, is not openable and closeable. The portion


40


may be fixed by a variety of means, such as by welding the portion


40


to the other walls of the container


10


or by other attachment mechanisms, such as screws, bolts, and the like.




In an alternative embodiment, the second portion


40


comprises a second door


40


so that side wall


12


is comprised of at least two doors, the first door


30


and the second door


40


. While doors

30


,


40


are in a closed position. It should be appreciated that although doors


30


,


40


are not shown as opened in

FIGS. 4 and 6

, doors


30


,


40


are capable of being opened at this point. In addition, it should be appreciated that while the components of the present invention are shown as part of door


30


, which is the right door of wall


12


when viewed from outside the container


10


, in the alternative, the components could also be part of door


40

,


4


, and


5


, door


30


includes an outer surface


32


and door


40


includes an outer surface


42


. Similarly, as shown in

FIGS. 3

,


6


, and


7


, door


30


includes an inner surface


34


and door


40


includes an inner surface


44


. As shown in

FIGS. 1

,


2


,


4


, and


5


, door


30


also includes a opening


36


that extends through door


30


from inner surface


34


to outer surface


32


. While opening


36


is shown as rectangular in shape, opening


36


may comprise other shapes, such as square or oval.





FIGS. 1

,


2


,


4


, and


5


illustrate the components that are positioned on the outside of the container


10


. In a conventional manner, with respect to both doors


30


,


40


of side wall


12


of container


10


, a vertically extending rod


50


is attached with each door


30


,


40


such that rod


50


is rotatable relative to its respective door


30


,


40


using a handle


64


. As shown, door


30


is engageable with rod


50




a


and its handle


64




a,


while door


40


is engageable with rod


50




b


and its handle


64




b.


Each rod


50


may be attached with doors


30


,


40


in a variety of ways, including using attachment mechanisms, such as bolts, screws, and the like, to allow the rod


50


to rotate. In one embodiment, each rod


50


is connected with doors


30


,


40


using brackets


52


and attachment mechanisms


60


.




As best shown in

FIG. 1

, each bracket


52


includes a half-circular section


54


and straight sections


56


,


58


. It should be appreciated that any number of brackets


52


may be utilized to attach each rod


50


with its respective door


30


or


40


. As shown, four brackets


52


are utilized for each


50


. For convenience, the middle two brackets


52


are not numbered in

FIGS. 1 and 2

. Each rod


50


is capable of fitting within each half-circular section


54


. Each straight section


56


,


58


defines an opening (not shown) therein. Attachment mechanisms


60


, such as bolts or screws, fit into the openings of the sections


56


,


58


to secure brackets


52


to doors


30


,


40


. Thus, after rod


50




a


is positioned next to outer surface


32


of door


30


, brackets


52


are attached to door


30


such that rod


50




a


is positioned between brackets


52


and door


30


. Rod


50




b


is attached with outer surface


42


of door


40


in a similar manner. After being attached with doors


30


,


40


using brackets


52


, each rod


50


is able to rotate relative to its respective door


30


or


40


within half-circular sections


54


of brackets


52


.




By comparing

FIGS. 4 and 5

, it should be seen that at least handle


64




a


is movable in an arcuate manner, such that it is capable of swinging inward to and outward from outer surface


32


of door


30


. In an exemplary embodiment, handle


64




b


is also movable in such an arcuate manner toward and outward from outer surface


42


of door


40


. Because each handle


64


is fixed to its corresponding rod


50


, the arcuate movement of each handle


64


in turn rotates its corresponding rod


50


. In a conventional manner, rotation of each rod


50


allows the engagement of a cam mechanism positioned at the top and bottom of that rod


50


to secure each door


30


or


40


in the closed position relative to the container


10


. Referring to

FIGS. 1 and 2

, in one embodiment, when each handle


64


is rotated which in turn rotates its corresponding rod


50


, latches


66


that are positioned on the top and bottom of rods


50


engage with protrusions


68


that protrude outward from top door frame


46


and bottom door frame


48


of the container


10


. This engagement of latches


66


with protrusions


68


of door frames


46


,


48


of the container


10


closes doors


30


,


40


of the container


10


.




Referring to

FIGS. 3

,


6


and


7


, the components of the sliding member securing mechanism


70


, which are generally positioned on the inside of side wall


12


of container


10


, will now be discussed. As shown in

84


is attached near a bottom portion of door


40


and a pin engaging hole


86


is defined in floor


49


of container


10


. Once door


40


is closed after latches


66


engage with protrusions


68


of door frames


46


,


48


, door


40


may be secured by inserting the heavy duty pin


84


into the pin engaging hole


86


.

10


, the other door


30


may be closed and locked. In the same manner as done with door


40


, door


30


is closed by moving handle


64




a


toward door


30


from the openable position (

FIG. 4

) to the closed position (FIG.


5


). The rotation of handle


64




a

64




a


causes at least a portion of sliding member


74


, through engaging member


80


, to slide behind inner surface


44


of door


40


. More particularly, in the openable state shown in

FIG. 6

, sliding member


74


is only positioned behind door


30


and not door


40


. Hence, door


30


is capable of being opened to gain access to the interior of container


10

50




a


is rotated which in turn moves engaging member


80


attached with rod


50




a.


This movement of engaging member


80


in turn moves sliding member


74


because engaging member


80


engages sliding member


74


through opening


76


. Thus, as shown in

FIG. 7

, once rod


50




a


is rotated to the closed position, sliding member


74


is positioned behind both doors


30


,


40


.




Using the sliding member securing mechanism


70


of the present invention, door


40


may not be opened because door


40


is locked in place, by inserting pin


84


into pin engaging hole


86


. Then, because doors


30


,


40


swing out to open, after sliding member


74


slides behind inner surface


44


of door


40


, door


30


may also not be opened. In particular, if a would-be intruder tried to pull on door


30


from outside of container


10


to open door


30


, door


30


will not open because a portion of sliding member


74


is positioned behind inner surface


44


of door


40


, which again is locked.
