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.

DESCRIPTION OF THE EMBODIMENTS
Reference will now be made in detail to the present embodiments of the invention, an example of which is illustrated in the accompanying drawings.
FIG. 1
illustrates a perspective view of a container
10
, such as a cargo style shipping container. The container
10
generally includes four side walls
12
,
14
,
16
,
18
, a bottom wall
20
, and a top wall
22
. 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
of the container
10
, while
FIG. 3
is a plan view of the inside of side wall
12
. Side wall
12
includes at least one door
30
that is openable and closeable to gain and prevent, respectively, access to the interior of the container
10
. In one embodiment, side wall
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
as shown are generally the same size, it should be appreciated that one of the doors may be larger in width and/or height than the other of the pair of doors. Doors
30
,
40
are typically about 4 feet in width and 8 feet in height. Doors
30
,
40
typically swing to the outside to gain access to the interior of the container
10
, similar to doors on a barn.
As shown in more detail in
FIGS. 4-7
, a sliding member securing mechanism
70
includes various components to allow doors
30
,
40
to be secured together and then, using a locking mechanism, to securely lock container

. In addition,
FIGS. 4 and 6
illustrate when doors
30
,
40
are in an openable position, while
FIGS. 5 and 7
illustrate when 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
, the left door of wall
12
.
As shown in
FIGS. 1
,
2
,
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
FIG. 3
, in one embodiment, a heavy duty bolt or pin
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
.
Referring to
FIGS. 3
,
6
, and
7
, sliding member securing mechanism
70

and bottom door frame
48
. Referring to
FIG. 3
, after door
40
is closed, door
40
is locked by inserting heavy duty pin
84
into pin engaging hole
86
into floor
49
of container
10
. Generally, an operator inserts heavy duty pin
84
into pin engaging hole
86
while he or she is inside the container
10
. Once this is accomplished, the operator exits the container
10
.
Once the operator exits the container
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
toward door
30
rotates rod
50
a
so as to engage latches
66
that are positioned on the top and bottom of rod
50
a
with protrusions
68
protruding from top door frame
46
and bottom door frame
48
.
In addition, the rotation of handle
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
. As handle
64
a
is moved toward door
30
to the closed state shown in
FIG. 7
, rod
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.
The present invention may be retrofitted to an existing container. Such a retrofit would require minimal modification to the existing doors of the container. Referring to
FIGS. 1-7
, the modifications to door
30
would include cutting opening
36
for engaging member
80
and may include cutting an opening for tab
92
when tab
92
is fixed to plate
78
. On inner surface
32
of door
30
, the modifications may include attaching reinforcing plate
78
to inner surface
32
, such as by screws or bolts; attaching channel member
72
to plate
78
, if present, or inner surface
32
, such as by welding; and positioning sliding member
74
within channel member
72
. To complete the installation, engaging member
80
and tab
90
would be attached to rod
50
a,
such as by welding. Additionally, in one embodiment, a cover box
110
(see
