DETAILED DESCRIPTION OF THE INVENTION

[0050] The disclosed invention makes it possible for the end user to move the shelf to another shelf position, changing the available space in a compartment, without the use of tools, to better utilize the space inside for what they intend to store. The need to comply with negative G-forces is not only required by the MIL-STD 209K, but is also important for any user who has our storage device on a vehicle driving down a bumpy road. The MIL-STD 209K is concurrently filed in an IDS, and the MIL-STD 209K is fully incorporated by reference herein. It is an advantage to be able to adjust the shelves without the need for tools. It is also advantageous for the mechanism which secures the shelf in its position to not take up storage space inside the cage when this position is not in use. Applicants have recently prepared a document entitled “TACTICAL LOCKER CWM OPERATING MANUAL” with a product code of SC-CW-MD-2D-03. This document is concurrently filed in an IDS, and the TACTICAL LOCKER CWM OPERATING MANUAL is fully incorporated by reference herein.

[0051] A storage device securing weapons must comply with several regulations to be considered secure, of which OPNAV INSTRUCTION 5530.13C (p. 3-2) is an important regulation with respect to this invention. This regulation dictates, among several other requirements, that a storage device securing weapons must weigh 500 lbs. or more to prevent theft of the storage device. The OPNAV INSTRUCTION 5530.13C is concurrently filed in an IDS, and the OPNAV INSTRUCTION 5530.13C is fully incorporated by reference herein. For storage devices weighing less than 500 lbs., the storage device should be secured without permanently fixing the device to its surroundings. Our solution does not require a separate lock or locking device and the solution cannot be separated from the device and will therefore always be available when needed. Our brake can be opened and secured by closing the door without a need for a separate lock.

[0052] FIG. 1 shows a partial view of a transportation cage 10 that comprises a first corner post 14, second corner post 18, third corner post 22, and fourth corner post 26. The transportation cage 10 also comprises a first door 30 and a second door 34. Each of the corner posts 14, 18, 22, 26 may have a first plurality of holes 38. In one embodiment the holes 38 may be oval or oblong shaped. Each of the corner posts 14, 18, 22, 26 may also have a second plurality of holes 40.

Insert the book of SHELF SUPPORT into oval hole on the CORNERPOST. Turn the SHELF SUPPORT to locking position. Do the same for opposite SHELF SUPPORT. The instructions for FIG. 10C are: Insert SHELF at an angle and push into the cage. The instructions for FIG. 10D are: Secure SHELF using hole for locking.

[0062] FIG. 11 shows a view of the intercage locking system. The cage 10 has a top, either solid, wire mesh, or other suitable top. The top is not visible in these views in order to show the intercage locking system. The cage 10 may have a plurality of top bars 70 along the perimeter of the top of the cage. One or more of the top bars 70 may have a horizontal through slot 74. The through slot goes through the top bars, from the interior of the cage 10 to the exterior of the cage. The cage may have one or more cross-top bars 78, that generally connect with the top bars 70, or other cross-top bars 78, or connect a top bar 70 with a cross-top bar 78. The cross-top bars 78 are not located along the perimeter of the cage 10, but rather are located above the interior of the cage 10. Inside one or more of the cross-top bars is a rod 82 with two right angle handles 86. In one embodiment, the right angle handles 86 of the same rod 82, are parallel to each other. The rods 82 are configured to be moved by a user inside the cage, please note the rods 82 are not going to be reachable from above the cage due to the top of the cage being in the way. The user will be able to slide the rod through the through slots 74 into adjacent cages through slots 74, and then rotate the rod so that the handles 86 are generally pointing down, so that the rod is locked into the top bar 70 of an adjacent cage 10. Please note that that the cross-top bar 78 has slots and openings to permit the sliding and rotating of the rod 82 and handle 86.

[0063] FIG. 12 shows a first cage 10A locked to a second cage 10B. First rod 82A extends from first cage 10A through a top bar 70A of the first cage 10A, via a horizontal through slot 74A of the top bar 70A and into a top bar 70B of the second cage 10B and a horizontal through slot 74B of the top bar 70B. The rod 82A has been rotated so that the right angle handles 86A prevent the rod 82A from disconnecting from the slot 74B, thereby locking cage 10A to cage Rod 82A is mostly inside of cross-top bar 78A. Similarly, second rod 82B extends from second cage 10B through a top bar 70B of the second cage 10BA, via a horizontal through slot 74C of the top bar 70B and into a top bar 70A of the first cage 10A and a horizontal through slot 74D of the top bar 70A. The rod 82B has been rotated so that the right angle handles 86B prevent the rod 82B from disconnecting from the slot 74D, thereby also locking cage 10B to cage 10A. Rod 82B is mostly inside of cross-top bar 78B. A third rod 82C is shown in the first cage 10A. This third rod 82C is not currently be used to connect an adjacent cage, but is available to connect another cage that could be adjacent to the width dimension of the first cage 10A. The third rod 82C is shown generally inside a cross-top bar 78C. Third rod 82C does not extend through horizontal through slot 74E of top bar 70D, because there is no other cage adjacent to the width dimension of cage 10A, and it is not necessary therefore to use rod 82C to lock cage 10A to an adjacent cage. Cross-top bar 78C and top bar 70D have slots or holes on the underside of the bars to allow the right angle handles 86C to point generally downward. Similarly, a fourth rod 82D is shown in the second cage 10B. This fourth rod 82D is not currently be used to connect an adjacent cage, but is available to connect another cage that could be adjacent to the width dimension of the second cage 10B. The fourth rod 82D is shown generally inside a cross-top bar 78D. Fourth rod 82D does not extend through horizontal through slot 74F of top bar 70E, because there is no other cage adjacent to the width dimension of cage 10B, and it is not necessary therefore to use rod 82D to lock cage 10B to an adjacent cage. Cross-top bar 78D and top bar 70E have slots or holes on the underside of the bars to allow the right angle handles 86D to point generally downward. Please note, in one embodiment, only one rod 82 is necessary to lock adjacent cages. So in FIG. 12, only rod 82A (or rod 82B) is required to lock cages 10A and 10B together.

[0064] FIG. 13 is a cross-sectional view of cages 10A and 10B. In this view, it can be seen how rod 82A is locked into top bar 70B, and rod 82B is locked into top bar 70A. Also shown in this view is a right angle handle slot 90A in cross-top bar 78A, that allows one to slide rod 82A right and left in order to lock into adjacent cages, and/or retract back into cage 10A. Slot 90A also has a hole or right angle slot to allow the right angle handle 86A to rotate into the down position shown in FIG. 13. Also shown in this view is a right angle handle slot 90B in cross-top bar 78B, that allows one to slide rod 82B right and left in order to lock into adjacent cages, and/or retract back into cage 10B. Slot 90B also has a hole or right angle slot to allow the right angle handle 86B to rotate into the down position shown in FIG. 13.

However, the brake and lock system 98 is made visible in this view so the reader can understand how the brake and lock system operates. The brake and lock system 98 comprise a foot pedal 102 that engages the brake. When the foot pedal 102 is depressed, it rotates a brake mechanism 106 that engages the brake and prevents one or more wheels 94 from freely rotating. In one embodiment the brake mechanism 106 is in communication with a brake rod 110 that can engage a brake on an adjacent wheel 94. The brake and lock system 98 comprises a lock lever 114. When the lock lever 114 is engaged, the brake is locked in an engaged configuration, and the braked wheels cannot be unbraked until the lock lever 114 is disengaged. The lock lever 114 is generally visible from behind the third post 26 and door 34, unless it is pushed in the direction of arrow 118 (see FIGS. 26 and 27).

[0076] FIG. 25 is a view of the brake and lock system 98 from FIG. 24, but with the foot pedal 102 in a down and braked position. In this view, one can see that the brake mechanism has rotated counter-clockwise about 35°.

[0077] FIG. 26 is a view of the brake and lock system 98 from FIGS. 24 and 25 but with the door 34 opened. With the door open, the lock lever 114 can be pushed in in the direction of the arrow 118. When pushed in, the lock lever 114 will block the brake mechanism 106 from rotating to an unbraked position. FIG. 26 shows the lock lever 114 in an unlocked position.

[0078] FIG. 27 shows the lock lever 114 pushed in (in the direction of the arrow 118), such that a portion of the lock lever 114 blocks the brake mechanism 106 from being able to rotate to an unbraked position. A portion of the lock lever 114 is unable to be seen due to the door 34 being in the line of sight of the lock lever 114 now that it is pushed into the locked position. However, the blocking portion 122 of the lock lever 114 can be seen blocking the brake mechanism 106.

[0079] FIG. 28 shows the lock lever 114 pushed in (in the direction of the arrow 118), such that a portion of the lock lever 114 blocks the brake mechanism 106 from being able to rotate to an unbraked position and the door 34 closed. In this view, most of the brake and lock system (except for the pedal 102) would be blocked from view due to the fourth post 26 and door 34. However, the parts of the brake and lock system 98 that would be blocked from view are made visible in this view in order that the reader can understand how the system operates. The door 34, in a closed position, makes it impossible to pull the lock lever 114 out, in a direction opposite arrow 118, in order to unlock the brake mechanism, and allow the brake mechanism to be put in an unbraked position.

[0080] FIG. 29 shows a close up view of the wheel 94 and brake and lock system 98. In this view the lock lever 114 is in an unlocked position and the brake pedal 102 is in an unbraked orientation.

[0081] FIG. 30 shows a close up view of the wheel 94 and brake and lock system 98. In this view the lock lever 114 is in a locked position and the brake pedal 102 is in a braked orientation.

[0082] FIG. 31 is a top view of the brake and lock system 98. In this view the lock lever 114 is in an unlocked position and the brake pedal 102 is in an unbraked orientation.

[0083] FIG. 32 is a top view of the brake and lock system 98. In this view the lock lever 114 is in a locked position and the brake pedal 102 is in a braked orientation.

[0084] FIG. 33 is a side view of the wheel 94 and brake and lock system 98. In this view the lock lever 114 is in an unlocked position and the brake pedal 102 is in an unbraked position.

[0085] FIG. 34 is a side view of the wheel 94 and brake and lock system 98. In this view the lock lever 114 is in a locked position and the brake pedal 102 is in a braked orientation.

[0086] The disclosed improvements to transportation cages have many advantages. The shelf system provides for a shelf that will not shift or come attached to the cage even if the cage is turned upside down, if the cage doors are closed. The intercage locking system will allow one to easily connect and lock one cage to another, thereby preventing theft of the cages and better securing the cages. Further the intercage locking system can be configured to lock the cage to an adjacent wall, column, or pillar. Once the cages are locked together, or to a wall, they cannot be unlocked unless someone opens the cage doors. The brake and lock system will lock the brakes on the wheels into an on position, and the brakes cannot be unbraked until the doors of the cage are opened.
